摘要

關(guān)鍵詞：插線板編程系統(tǒng)；并聯(lián)位置;電子連接器。
本發(fā)明涉及設(shè)備和流程的改進(jìn)插線板的編程系統(tǒng)，更特別的設(shè)備和注重孔加工工藝的插線板面板。
插線板，也被稱為一個(gè)跳線盤，是一個(gè)裝置的多個(gè)連接到多個(gè)第一電路的插頭可以選擇性地與多個(gè)連接到多個(gè)第二線路的連接器的連接。插線板被用來(lái)，例如，在電話交換系統(tǒng)和電子計(jì)算機(jī)。
接線板上的連線編程系統(tǒng)由兩個(gè)配合面板。一個(gè)被安裝到計(jì)算機(jī)上，而另一個(gè)被稱為便攜式面板，是可移動(dòng)的。便攜式面板上有孔，其中有大量的連接器插頭的可移動(dòng)地插入的矩陣。這是可能的計(jì)算機(jī)通過(guò)在選定的孔在來(lái)自計(jì)算機(jī)的遠(yuǎn)程位置插入適當(dāng)?shù)牟孱^進(jìn)行編程。在同一時(shí)間的計(jì)算機(jī)可以與布置另一便攜式面板上不同的程序操作，節(jié)省了昂貴的計(jì)算機(jī)時(shí)間。插線板編程系統(tǒng)的這種一般類型被進(jìn)一步在美國(guó)專利號(hào)2647244中 Dewky和Zatsky所述，發(fā)行于1953年7月28日。
在插線板的制造中的一個(gè)主要問(wèn)題是保持在觸點(diǎn)之間的每個(gè)接觸件和適當(dāng)?shù)拈g距的正確對(duì)準(zhǔn)。例如，一個(gè)簡(jiǎn)單的插線板可以由矩形矩陣接觸高和寬，為總共1800接觸。除非個(gè)別接點(diǎn)準(zhǔn)確對(duì)準(zhǔn)并間隔開，它們將不進(jìn)行電接觸。
關(guān)于以合理的成本多次接觸的準(zhǔn)確位置的問(wèn)題已經(jīng)解決了非屏蔽插線板編程系統(tǒng)。這樣的接觸，包括金屬?gòu)椈苫蚣忸^的，可以被定位在一個(gè)矩陣的形式，并放置在一個(gè)剛性的，模制的塑料框。然而，問(wèn)題是在插線板與屏蔽同軸電纜的使用更加困難。這樣的電纜包括一個(gè)內(nèi)導(dǎo)體，絕緣體和外導(dǎo)體。終止這種電纜是一個(gè)導(dǎo)電連接器，而導(dǎo)體周圍的絕緣層和接線板上的連線面板，這是導(dǎo)電的。
但一直未能。迄今為止，做出插線板用于與同軸電纜所要求的精度在合理的成本下。一種已知的方法是將鉆單個(gè)圓形孔的導(dǎo)電性金屬板在一個(gè)序列中，得到的一千個(gè)或更多的孔的矩陣。這個(gè)過(guò)程必然是緩慢和昂貴的，甚至是編程機(jī)床工具。定位在孔中的連接器包括由塑料絕緣的圓形柄部圍繞的金屬尖頭的。由于其圓形形狀時(shí)，往往會(huì)轉(zhuǎn)動(dòng)并變得不正確地對(duì)準(zhǔn)。
另一種已知的插線板是由大量單個(gè)元件組成。每個(gè)元件包括由矩形塑料絕緣包圍的彈簧接觸。這些元件被裝入由環(huán)環(huán)相扣的金屬網(wǎng)格形成開口，形成環(huán)環(huán)相扣就像一個(gè)雞蛋紙箱。由于元件和金屬網(wǎng)格部件裝配，他們可能會(huì)建立容差的變化。舉例來(lái)說(shuō)，如果有更多的單元格在一行中的第一部分是超大元件的話，那以后的行是矮小的，該行的總尺寸可能是正確的，但在中心附近的接觸可能會(huì)出狀況。此組件中，由于需要進(jìn)行手工制造和恒定公差檢查，是相對(duì)昂貴的制造。
本發(fā)明通過(guò)提供一種高度精確的和相對(duì)便宜的插線板面板克服了現(xiàn)有設(shè)備的困難。該面板被加工金屬的，最好是在一個(gè)高精確度的銑床上。加工形成一組具有凸起的肋上的面板和一角度運(yùn)行于第一組相似的平行凹槽的所述第一表面上運(yùn)行的一種方法，切成相對(duì)表面平行的槽。優(yōu)選地，所述槽在一個(gè)表面是垂直于所述凹槽中的另一個(gè)表面上。交叉或垂直的槽的總深度大于所述板的厚度。因此，劃線槽形成四邊多邊形的孔。多個(gè)導(dǎo)電彈簧指每個(gè)由絕緣性伴侶現(xiàn)實(shí)，優(yōu)選塑料絕緣包圍，是壓入配合到所述多邊形孔。這些彈簧的手指形成了一套固定的面板上不可移動(dòng)屏蔽觸點(diǎn)。它們合作提供一組插入配合，便攜式面板來(lái)完成多個(gè)接線板上的連線的編程系統(tǒng)的電路的可移動(dòng)的同軸插頭。
因此，它是本發(fā)明的主要目的在于提供一種相對(duì)便宜的插線板系統(tǒng)，其中的接觸是非常精確地對(duì)齊和定位。
本發(fā)明的另一個(gè)目的是在系統(tǒng)內(nèi)保護(hù)每個(gè)單獨(dú)的連接器，使連接器可以與同軸電纜使用。
本發(fā)明的另一個(gè)目的是提供正確取向的連接器，以便它們使與其配合插頭電接觸良好。

各個(gè)連接器的結(jié)構(gòu)，并且其絕緣性，示于圖6-9。如圖示6，絕緣塊18是由兩個(gè)相同的和互補(bǔ)的部分18a和18b，且它們具有19a和19b的插槽。所述連接器彈簧指20是一個(gè)導(dǎo)電彈性材料，例如鈹銅。彈簧指20包括一個(gè)彎28和29定位給的一個(gè)力，并讓與其交配插腳接觸。彈簧指20還包括設(shè)置為與對(duì)應(yīng)的部分33a和塊18的33b的凹槽31和32。
在彈簧指和其絕緣的組件，彈簧指20的電接觸第一裝配到一個(gè)時(shí)隙，假設(shè)19b上。然后第18A旁邊就是單元18和彈簧鉤爪20定位在槽19A?；蛘?，塊18可在一塊與彈簧鉤爪20成形到位，或模制成單件模制的塑料，然后將彈簧鉤爪20插入其開口。優(yōu)選方框18有一橫截面比孔11稍大并壓入從面板10的背面的孔11。將壓入料伸長(zhǎng)或扭曲塊18的塑料，使該塊被固定到位。塊18可替代地，可以代替由其它的方法，如粘接保持。步驟21a和21b上塊18防止其從板10向前拉。塊18可以由任何絕緣材料，優(yōu)選塑料，如己內(nèi)酰胺的聚合物，如尼龍能夠被壓入孔11和保持代替由面板的周圍的那些孔交叉的肋。從經(jīng)濟(jì)上考慮設(shè)計(jì)也建議做兩個(gè)成型和相同的半部分18a和1811各有面51在組裝雙段組合在一起的彈簧鉤爪20相互并列的交配塊18。該組件在孔11的壓裝在保持互鎖關(guān)系的部分。圖。2和3中，只顯示兩個(gè)塊18和彈簧指20，但是，通常會(huì)有一個(gè)塊18，并且彈簧指20對(duì)每個(gè)孔11。彈簧指20的后端伸出面板10，并且適合于被連接到一個(gè)配套連接器（未示出）。合適的配合連接器可以是其中被強(qiáng)制通過(guò)彈簧指20的后端部的部分通道構(gòu)件的形狀。

面板22是插頭24已經(jīng)插入其孔23。因此，當(dāng)面板22位于靠近面板10被偏置向下，然后向上滑動(dòng)，使齒尖26與彈簧鉤爪向上滑動(dòng)，使齒尖26與彈簧鉤爪20。
中間金屬屏蔽層30也可使用。最好是屏蔽30是由交錯(cuò)表與在雞蛋箱制成開放式加盟盒的形式。屏蔽層30接地到面板10。屏蔽30被定位周圍的每一個(gè)齒尖26和彈簧指20從其它屏蔽各電路。屏蔽30可以被刻凹痕放進(jìn)研磨槽17。外屏蔽層（未示出）類似，屏蔽30可用于包圍插頭的后端18后面的固定板10。這樣的外屏蔽層也將被接地到板10，并提供用于塊18的后端部的單個(gè)屏蔽。
盡可能多的變化可以作出在上述結(jié)構(gòu)中，并且可以做出本發(fā)明的許多不同實(shí)施例而不脫離其范圍，意圖是包含在以上描述中或在附圖中所示的所有內(nèi)容應(yīng)被解釋為說(shuō)明性的，而不具有限制意義。

PATCHBOARD PROGRAMMING SYSTEM
ABSTRACT OF THE DISCLOSURE
An electrical patch-board which includes a conductive plate having first and second arrays of parallel slots dis-posed on opposite sides of the conductive plate with the arrays of slots being mutually perpendicular to each other and recessed to a depth sufficient to form a matrix of holes through which are inserted electrical connectors having insulated sleeve portions shaped to form press fits between the parallel walls of at least one of the first or second arrays of slots.
Key Words: patch-board programming system; arrays of slots; electrical connectors.
This invention relates to apparatus and processes for an improved patch-board programming system and more particularly to apparatus and processes concerning holes in a patch-board panel.
A patch-board, also known as a patch bay, is a device where by a plurality of plugs connected to a first plurality of circuits may selectively connect with a plurality of connectors connected to a second plurality of circuts.Patch-boards are used, for example, in telephone switching systems and electronic computers.
The patch-board programming system consists of two mating panels. One is attached to the computer and the other, called the portable panel, is removable. The port-able panel has a matrix of holes in which a large number of connector plugs may be removably inserted. It is possible to program the computer by inserting the proper
plugs in selected holes at a location remote from the computer. At the same time the computer may be operated with a different program arranged panel, saving costly computer time.Patch-board programming system is on another portable.This general type of further described in U.S. Patent No. 2,647,244 to Dewey and Zatsky, issued 7.28. 1953.
The problem of accurate placement of many contacts at a reasonable cost has been solved in unshielded patch-board programming systems. Such contacts, consisting of metal springs or prongs, may be positioned in the form of a matrix and placed in a rigid, molded plastic frame.However, the problem is more difficult in patch-boards for use with shielded coaxial cable. Such cable consists of an inner conductor, an insulator, and an outer conductor. The termination for such cable consists of a conductive connector, insulation around the conductor, and the patch-board panel, which is conductive.
It has not been possible, heretofore, to maze a patch-board for use with coaxial cable which possesses the required accuracy at a reasonable cost. One known ;method is to drill individual round holes in a conductive metal panel in a sequence to obtain a matrix of a thousand or more holes. This process is necessarily slow and relatively costly even with programmed machine tools. The connectors positioned in the holes consist of a metal prong surrounded by a round shank of plastic insulation. Due to their round shape, they tend to rotate and become in-correctly aligned
Another known patch-board is made up of a large number of individual cells. Each cell consists of a spring con-tact surrounded by rectangular plastic insulation. The cells are fitted into openings formed by interlocking metal grids, the interlocking being formed like an "egg carton." As the cells and metal grid members are assembled, they may build up tolerance variations. For example, if more of the cells in the first part of one row are oversized and the cells later in the row undersized, the overall dimension of the row may be correct and yet contacts near the center may be out of position. This assembly, due to the need for hand fabrication and constant tolerance checking, is relatively expensive to manufacture.
The present invention overcomes the difficulties of the prior devices by providing a highly accurate and relatively inexpensive patch-board panel. The panel is machined of metal, preferably on a high-accuracy milling machine. The machining forms a set of parallel grooves having raised ribs running one way on the first surface of the panel and similar parallel grooves running at an angle to the first set and cut into the opposite surface. Preferably the grooves in one surface are perpendicular to the grooves in the other surface. The total depth of the crossing or perpendicular grooves is greater than the thickness of the panel. Accordingly, the crossed grooves form four-sided polygonal holes. A plurality of conductive spring fingers each surrounded by insulating material, preferably plastic insulation, are force-fitted into the polygonal holes. These spring fingers form a set of non-removable shielded contacts on the fixed panel. They cooperate with a set of removable coaxial plugs inserted into a mating, portable panel to complete a plurality of circuits of the patch-board programming system.
It is therefore a principal objective of the present invention to provide a relatively inexpensive patch-board system in which the contacts are very accurately aligned and positioned.
It is a further objective to shield each individual connector within the system so that the connectors may be used with coaxial cable.
It is a further objective to provide correct orientation for the connectors so that they make good electrical contact with their mating plugs.
It is an additional object to provide an improved method for the manufacture of patch-boards.
Other objects and features will become apparent from the description taken in conjunction with the drawings, in which:

FIGS. 1-5 show an electrically conductive fixed rear panel 10 with a plurality of polygonal rectangular holes 11. Holes 11 are produced by a novel and inexpensive process. Prior to machining, panel 10 may be a flat metal plate having flat surfaces 12 and 15. A first surface 12 machined or milled, for example, to a first depth 13 producing a first set of parallel slots 14 having upstanding ribs between the slots. The depth and position of the slots may be machined, or otherwise fabricated, to an accuracy of 0.005 inch using, for example, conventional milling machines. Opposing surface 15 is likewise machined to a second depth 16 producing a second set of parallel slots 17 and ribs which are, preferably, perpendicular to the slots 14 and ribs of the first surface.Holes 11 are produced by the sum of depths 13 and 16 being greater than the distances of depths 13 and between surfaces 12 and 15Preferably each of the slots exceeds in depth one-half the thickness of the panel 10. Alternatively, one set of slots on one surface may have greater depth than the other set, as long as the total depth of the two cuts exceeds the thickness of the plate so as to produce polygonal holes 11 at the intersections of slots 14 and 17.
Slots within a particular set 14 or 17 are preferably parallel to each other and of uniform cross-sectio..Holes 11 are rectangular because slot sets 14 and 17 are perpendicular to each other.If desired some other quadrilateral shape of suitable angle between slot sets 14 and 17 may be chosen.
The construction of the individual connectors, and their insulation, is shown in FIGS. 6-9. As is shown in FIG. 6, insulating block 18 is made up of two identical and complementary sections 18a and 18b having slots 19a and 19b, respectively. The connector spring finger 20 is of a conductive spring material; for example, beryllium copper.Spring finger 20 includes a bend 28 and a detent 29 to give a press force and to make contact with its mating prong. Spring finger 20 also includes protruding portions 31 and 32 provided for interlocking with the recessed shoulders of corresponding portions 33a and 33b of the block 18.
In the assembly of the spring finger and its insulation, the electrical contact of spring finger 20 is first fitted into one slot, say 19b.Then section 18a is positioned next to section 18b and spring finger 20 is positioned in slot 19a. Alternatively, block 18 may be molded of plastic in one piece with the spring finger 20 molded in place,or molded in one piece, and then the spring finger 20 inserted into its flat opening. Preferably block 18 has a cross-section slightly larger than holes 11 and is fitted into holes 11 from the back of panel 10. The press fitting extrudes or distorts the plastic of block 18 so that the bock is firmly held in place.Block 18 may, alternatively,be held in place by other methods,such as adhesive bonding. Steps 21a and 21b on block 18 prevent it from being pulled forwardly made of any insulating from panel 10. Block i8 may be made of any insulating material, preferably a plastic such as a polymer of caprolactam such as nylon capable of being press fitted into holes 11 and held firmly in place by the crossed ribs of the panel around those holes. Economy of design also suggests making block 18 of two molded and identical half sections 18a and 18b, each having faces 51 for mutual juxtaposed mating upon assembiling the pair of sections together on spring finger 20.The press fit of this assembly in hole 11 maintains the sections in interlocking relation. FIGS.2 and 3 show only two blocks 18 and fingers 20 in place;However,there will usually be a block 18 amd finger 20 for each of the holes 11.The rear end of spring finger 20 extends beyond panel 10 and is adapted to be connected to a mating connector (not shown). A suitable mating connector may be in shape of a partial channel member which is forced over the rear end of spring finger 20.
FIG. 1 shows a portable second panel 22 which has holes 23 corresponding to holes 11 and is removably positioned near panel 10.Some of the holes23 are removably filled with coaxial jack plugs 24.Each of the plugs 24 has an outer shell connected to the outer conductor of a coaxial cable (not shown). The conductive prong 26 of plug 24 is connected to the inner conductors of the coaxial cable. A suitable coaxial jack plug is described in U.S. Patent 2,983,895, to Pasik, issued May 9,1961. Preferably, panel 22 is conductive so that the surface defining hole 23 makes contact with outer conductive shell 25 of plug 24. Panel 22, in that case would be a grounded plate and would act to ground the outer conductive shell 25 of the plug 24.
Panel 22 may have plugs 24 already inserted into its holes 23. Therefore, when panel 22 is positioned near panel 10 it is offset downwardly and then slid up,allowing prongs 26 to contact spring fingers slid up, allowing prongs 26 to contact spring fingers 20. Blocks 18 properly orient spring fingers 20 in order to make this contact.
Intermediate metal shield 30 may be used. Preteranty the shield 30 is in the form of open-ended joined boxes made from interleaved sheets as in an "egg crate".Shield 30 is grounded to panel 10.Shield 30 is positioned around every prong 26 and spring finger 20 to shield each circuit from the other. The shield 30 may be notched to fit into the milled slots 17. An outer shield(not shown) similar to shield 30 may be used to surround the rear end of plugs 18 behind fixed panel 10. Such an outer shield would also be grounded to panel 10 and provide for individual shielding of the ends of blocks 18.
As many changes could be made in the above construction and many different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
What is claimed is:

(a) a conductive panel having first and second surfaces spaced apart a preselected distance.
(b) a first array of parallel lengthwise slots recessed into said panel a preselected depth from said first surface for forming a first array of ribs.
(c) a second array of lengthwise slots recessed into said panel a preselected depth from said second surface for forming a second array of ribs perpendicular to said first array of ribs, the sum of the depths of said first and second arrays of slots beine at least equal to the thickness between said first and second panel surface for forming receptacle holes at the intersections of said slots intermediate said panel faces.
(d) a plurality of electrical connectors inserted through said receptacle holes including each of said electrical connectors including a flat spring conducting member one end of which is surrounded by an insulated sleeve shaped to form a press fit within at least one slot of said first or second arrays of slots.
2. The patchboard as defined in claim 1 wherein saidinsulated sleeve is made up of a pair of similar insulators,each of said insulators having engaging means for interlocking the assembled insulators on said flat conducting member, the width of each insulated sleeve being slightly larger than the width of each slot of said first array of slots to press fit the inserted connector between one pair of said first array of ribs for captivating same in its receptacle hole and for maintaining the connector components in assembled interlocked status.
3. An insulated electrical connector designed for insertion through a receptacle hole in a conductive patchboard having parallel walls adjacent said receptacle hole, comprising in combination,
(a) a lengthwise electrical conducting member,
(b) a pair of similar lengthwise electrical non-conducting insulators each having faces designed for mutual juxtaposed mating upon assembling said pair together on said conducting member,
(c) means on said conducting ,member for interlocking said pair of insulators on said conducting member,
(d) means on said insulators for interlocking said conductor to said insulators, one of said interlocking means including serrations providing captivated engagement with the other of said interlocking means,where in said connector is firmly interlocked upon pressed fit insertion between the parallel walls adjacent said receptacle hole.
4. The connector as defined in claim 3 where in said insulator interlocking means includes lengthwise slots having spaced shoulders, said conducting member being flat and resilient, and the interlocking means thereof including said serrations spaced there along on opposite sides of said conducting member for straddling the shoulders of said assembled insulator members.
