Description

*οΐ3'Λ ττ3« *^osm -tana Hermaphroditic electrical connector THE 3ENDIX GORPORATIOK C:-37000 In order to link the operating unite or components of an electrical installation, it is known to make use of multi-wire cables which are interconnected by means of terminal connectors. Such coupling devices are usually of the male and female type, the cable interconnections being made by properly mating male and female contacts of the connectors.

This implies the necessity of constructing and storing separately male and female contacts, and to keep in store, for maintenance sake, a double series of contacts.

In order to simplify the industrial production of such contacts and to make easier the watching of the contacts stored for maintenance, the present invention discloses a hermaphroditic type electrical connector each contact of which comprises several fine wires bundled together to form a brush contact. When the contacts are in mated relationship, their respective file wires are intermingled so as to provide a very good and reliable electrical circuit relationship therebetween.

The invention will be now described by way of example and with reference to the accompanying drawings wherein : Fig. 1 is a perspective view of a connector assembly; Fig. 2 is a sectional view of a first embodiment of a hermaphroditic contact according to the invention; Fig. 3 is a magnified view of a contact wire; Fig; 4 shows two contacts in mated relationship; and ' Fig. 5, 6, 7 are respectively sectional view of contacts according three other embodiments of the invention.

Referring now to the drawings , FIGURE 1 illustrates a connector assembly that is comprised of a first assembly 1 and a second aesembly 2, both of which embody the principles of the invention.

, The first ssembly 1 comprises a housing 8, having a plurality of passages 23, a plurality. of ducts 21. and 22 disposed in the passages 23, and an electrical connector contact 11 disposed in each of said ducts 21 and 22.

The housing 8 is generally comprised of a nonconducting material and ma y take any particular configuration.

The ducts 21 and 22 are disposed within the passages 23 in a predetermined manner so that some of the ducts 21 extend out of the pas sage 23 and other of the ducts 22 terminate within the passage 23. In this embodiment the position of the ducts 21 and 22 determine the male and female portion of the assembly 1.

Located within each duct 21 , 22 is an electrical contact 11 similar to that shown in FIGURE 2. The shoulder 17 of the electrical contact 11 assists in positioning the electrical contact 1 1 in its proper place within the duct 21 , 22. In the first assembly, the electrical contact 1 1 is located in the ducts 21 that extend out ± «.ne passage 23 so that neither the hous ing 10 nor the Wi res 12 ex-tend out of the duct 21. · The electrical conductor 5 that is to be connected to another conductor is in electrical circuit relationship with the electrical contact 1 1.

Similarly, the second assembly 2 comprises a housing 9 having a plurality of passages 23 therein, a plurality of ducts 21 and 22 located in each o the housing passages 23, and an electrical contact 11 located in each of the ducts 21 , 22. The shape of the housing 9 and the arrangement of the passages 23 a re identical to the first assembly housing and passage arrangement so that the duct 21 and 22 may enter the passage 23 in assemblies 8 and 9 in a predetermined relationship..

\ III the second assembly 2 there are a plurality of ducts 22 that terminate within the passage 23 of the second assembly 2. This is so the passages 23 may receive ducts 21 from the first as sembly 1. The re are also a plurality df ducts 21 that extend beyond the passage 23 for mating with the passages 23 in the first assembly 1.

Located in each duct 21 , 22 are electrical contacts 11. Extending beyond the duct 22 is a portion of the housing 10 and wires 12 of the electrical contact 11 that, will be inserted into the. duct 1 when duct 21 is inserted into passage 23 of the second assembly 2.

• A sepond conductor 6 is in circuit relationship with the electrical contact 1 1 so that when the first as sembly 1 is in mated relationship with the second assembly 2, the Wires 12 of the first and second assembly a re intermingled with and in cohtac .with each other whereby the first electrical conductor 5 is Although a plurality of ducts 21 and 22 and electrical contacts 11 arc shown; this connector may also be used for connectin as few as two wires in electrical circuit relationship. Further, the first assembly 1 could be arranged such that all the ducts .21 and 22 terminate within the passages 23 making it a receptacle while all the ducts 21 and 22 located in the second assembly 2 may extend beyond the housing making it a plug. However, the combination of male and female contacts in each as sembly makes it possible to key one assembly to another so that only one mating relationship is possible. Also, the ducts 21 and 22 could be eliminated from the assembly and the electrical contacts 1 1 placed directly into a housing. In this regard, resilient inserts, adapted to receive and locate the contacts 11 in a predetermined position would comprise the connector assembly. In the embodiment shown in FIGURE 1 , the passages 23 and ducts 21 and 22 are used to align and position the electrical contacts 11.

FIGURE 2 is a cross-sectional view of a preferred embodiment of an electrical connector contact 11 that embodies the principles of this invention. The elongated housing 10 , which is fabricated from an appropriate conducting mate rial, has an axial passage 14 in one end for receiving an electrical conductor (not shown). The other end of the housing 10 has an axial passage 13 of two different cross- sections', for receiving a plurality of wires 12. Generally, seven or more wires 12 fill the inner portion B of the passage 13 and. are crimped at one or more points 19 into place. However, they may be solde red or brazed into position so long as all of the wires 12 are in electrical circuit relationship with one another. The end portion A of the passage 1 3 has a larger axial cross- sectional area than the axial cross-sectional area of the interior portion A of the passage 13. This larger cross- sectional area provides a space between the wires 12 and the inner wall of the end portion of the passage 13 for s r in of wi es 12 in a radial direction. The o enin at the end ortion of the passage 13 is chamfe red inwa rdly to facilitate the passage of similar wires (not shown) into the end portion of the passage 1 3. When the wires of a similar assembly are axialfy in line with the wires 12 of this assembly, and an axial force is applied thereto, the wires of this assembly expand within the confines of the end portion A of the housing passage 13 as the wires of the other assembly enter the passage 13 and intermingle with the wires of this assembly. This action completes the electrical circuit relationship between the two assemblies.

Preferably, the distance D that the wires 12 extend beyond the housing 10 is less than the length of the end portion A of the housing passage 13. This will insure that when all wires 12 are in mated relationship with the wires of a similar contact they are surrounded by and supported by the housing 10. This confine 8 the wires 12 to a given space and helps to prevent radical bending of the wires that prevents a wire from entering the passage 13 in the housing 10 when the contacts are placed in mated relationship.

FIGURE 3 is a magnified view of one of the wires 12 that are mounted in a housing to accomplish the objects of this invention. In this embodiment, for ease of assembly, both ends of wire 12 have a tapered or an angled surface 3 to facilitate eliding movement upon contact with the wires of another connector. The wire shown may be of any conducting material depending upon the strength and conductivity requirements. An example of one preferred material is beryllium- copped wire having a silver coating thereon. When beryllium- copper is used, it is preferred that for a housing 1 1 , having, an outside diamete r of about '. 1 ^ 5 mm 1, that the wires 12 have a length of about . - 10 mm and a diameter of about . G» l5 mm . In this embodiment, wires having a diameter less than 0, 25 mm and greater than .0*025 mm are preferred. A s previously mentioned, for structural purposes, it may be desirable to limit the length of the wire 12 to FIGURE 4 illustrates hermaphroditic contacts , similar to the one shown in FIGURE 2, in mated relationship. In this prefer i ed embodiment, it is shown how the end portions A of the housing passages 13 confine the intermingled wires 12 to a specific space. Although it is , not necessary that the ends of each housing 1 0 contact each other, it is preferred that they do. Such an arrangement prevents the buckling of the wires should an unusually high amount of axial force be exerted on the housings 10. Each of the housings 10 include a second axial pas sage 14 for receiving an electrical conductor {not shown).

FIGURE 5 is a cross- sectional View of a preferred embodiment of a hermaphroditic electrical contact 11 which characterizes this invention. In this embodiment, the wires 12 are mounted in the axial passage 13 in the housing 10. However, the axial passage 13 is of uniform cross- section and there is no end portion which is spaced' from the wires mounted therein. This type of contact may be mated with the electrical contacts shown in FIGURES 2, 6 or 7 and with contacts identical to that shown in this figure.

FIGURE 6 is a cross-sectional view of still another preferred embodiment of a hermaphroditic -electrical contact which characterizes this invention. In this embodiment, the wires 12 do not extend beyond the end of the housing 10, but terminate at or within the housing 10. The end portion A of the passage 13 has a larger cross-section than the interior passage portion B for containing the wires 12 to a predetermined space when mated with the wires of another contact. This type of contact is especially adapted to receive the contact shown in FIG URES 5 and 7 but may also receive the contact shown in FIGURE 2.

FIGURE 7 is a cross -sectional view of a double ended hermaphroditic electrical contact which embodies the principles of this invention. In this embodiment, the wires 12 of either end of the contact 11 can be mated with the contact
