MULTIPLE WIRE ELECTRICAL CONNECTOR Filed March 21, 1963 FIGS INVENTOR A. C. AE L L ER k W WW/s A TTORNEV United States Patent 3,185,955 MULTIPLE WERE ELECTREAL QQNNECTOR Arthur C. Keller, Bronxville, N,Y., assignor to Bell Telephone Laboratories, Incorporated, New York, NAG, a corporation of New York Filed Mar. 21, 1963, Ser. No. 266,842 11 Claims. (61. 339-91) This invention relates to devices for making connections between electrical conductors and more specifically to electrical devices having mating terminals wherein the contact pressures therebetween are determined by torsional forces.
In general, multicircuit connectors comprise two mating insulating blocks having a plurality of complementary metallic terminals positioned within the blocks in a predetermined geometric pattern. The terminals usually make contact with each other during the process of mating the two blocks and depened upon some type of spring force to supply adequate contact pressure.
Such devices include inherent disadvantages. For example, during the process of mating the two blocks, the paired terminals are usually required to touch and slide over each other a considerable distance before the blocks mate with each other. Such a requirement is intended to insure a cleansing of contact surfaces or an adequate buildup of contact pressure but may result in excessive wear on the terminals and their subsequent damage. In addition, other connectors, in order to insure electrical continuity, include intricately shaped terminals having precious metal multiple spring contacts. These complex shapes require expensive manufacturing processes, not only to shape the terminals, but also to guarantee the dimensional tolerances required to give adequate spring pressures.
Further problems, in most cases, are encountered in endeavoring to insure that the terminals of one block will properly pair or come in contact with the terminals of the other block when the blocks are mated. Suggestions of the prior art include floating or mounting the contacts loosely or building in sufiicient play in the blocks to allow the contacts to find one another. Both ideas, and others similar to them, multiply the dimensional problems already mentioned. Also, when wired into circuits, the floating action may be reduced or lost with consequent loss of performance.
It is an object of this invention to simplify and improve the structure of these devices.
Another object of the invention is to obviate the necessity for requiring strict dimensional requirements in order to insure the proper mating of insulating blocks and terminals.
Another object is to reduce the contact force between the mating terminals without loss of reliable performance by minimizing Wear products due to the reduced sliding action of the mating contacts.
A further object of the invention is to obtain multiple point contact between the terminals of two mating insulating blocks.
A still further object of the invention is to supply adequate contact pressure through the incorporation of torsional forces.
The invention basically comprises two mating insulating blocks containing, in a predetermined geometric pattern, a plurality of securely mounted mating terminals. The latter are elongated and so mounted in the blocks and shaped on their contacting extremities that one induces a rotational displacement and a consequent torque in the other when the blocks are brought together. The extremities of the terminals in one block are V-shaped similar to a chisel while those of the other block are notch.
shaped approximating the complement of the chisel-shaped terminals. Because of the shape of the extremities and the induced torque, two contact areas and an adequate contact force are provided when the blocks are mated. In addition, the contact force can further be preset by changing the cross sections of the terminals and their relative placement in the blocks.
An advantage of the device is that a very small movement of one terminal with respect to its mating terminal is required to induce a torque of suificient magnitude to provide adequate contact force. A related advantage is that miniature connector designs of high reliability are possible.
Another advantage is that the chisel and notch-shaped extremities are simple and inexpensive to manufacture and such dimensional tolerances that are deemed necessary can be easily maintained by existing standard machine shop practices and equipment.
A feature of the invention is a connector wherein strict dimensional tolerances are minimized.
Another feature of the invention is that the interaction of the two mating terminals automatically provides two contact surfaces to insure electrical continuity between them.
Other objects, advantages, and features of the invention will be obvious and understood from the following detailed description when read in conjunction with the drawing, in which:
FIG. 1 is an exploded perspective View of one embodiment of the invention;
FIG. 2 is an enlarged perspective view of the extremities of the terminals contained in the mating blocks;
FIG. 3 is an enlarged section view taken generally along the lines 33 of FIG. 1;
FIG. 4 is an enlarged plan view illustrating the contacting extremity of the female terminal and shows the free position of the terminal in solid lines and the rotationally displaced position of the terminal in broken lines;
FIG. 5 is an enlarged elevation view of the contacting extremities of the terminals; and
FIG. 6 is an enlarged elevation view of the contacting extremities of the terminals when they are mated showing the two con-tact points a and b.
As shown in the various figures of the drawing, the invention comprises basically two mating insulating blocks 1% and 11 having a plurality of electrical terminals solidly mounted therein. The insulating block it) further comprises a mounting member 17 having projecting at right angles therefrom four continuous side walls 18. The male terminals 15 of the connector are solidly fixed in the ember I7 such that the terminals 15 extened through it a predetermined distance on each side of the member 17.
The insulating block 11 also includes a mounting member 1? and four side walls 20 but the side walls 20 are so located that the side walls 18 of the block 10 will fit inside the walls 2% of block 11. When the two blocks 10 and 11 are brought together, they form, generally, 3. rectangular block.
The fit between the side walls '13 and 2% must be dimensionally close enough to prevent the two blocks 10 and 11 from rotationally moving with respect to each other when the blocks are subjected to subsequent forces and torques.
Solidly fixed in the mounting member 19 of block 11, is a plurality of female terminals 16. The terminals 16 are so placed that they will pair with the geometrically patterned terminals 15 of block it when the two blocks 16 and 11 are mated with each other.
The male terminals 1d of block 1% are elongated, and rectangular cross section and terminate on the electrically contacting extremity in a cam, Wedge or V-shaped chisel minal.
.point 21. The other extremity 22 has an appropriately shaped wire receiving configuration for receiving the ining, crimping, wire wrapping, solderless quick clip connecting and other various well-known prior art connecting processes.
The terminals 16 of the block 11 have on their contacting extremity 24 a receiving, interfitting or V-shaped notch that is approximately the complement of the chiselshaped extremity 21 of terminals 15. However, the angle B shown in FIG. formed by the notch-shaped extremity 24 is slightly smaller than the angle or (also shown in FIG. 5) formed by the chisel-shaped extremity 21.- Thus, when the two terminals 15 and 16 are mated, two contact areas a "and b are assured as shown in FIG. 6.
The terminals 16, like the electricl terminals 15, have a rectangular cross section and are elongated, having an electrically contacting extremity 24 previously described and a cable wire receiving extremity 25. End 25, as is end 22 of terminal 15, is appropriately shaped according to the numerous known means for connecting the incoming wires 'of a cable or to provide for other types of elec- 'trical connections.
In contrast to the terminals 15, the cross section of the terminals 16 are reduced in a portion 26 near the contactingextremity 24. The reason or purpose for the cross sectional reduction will subsequently be apparent.
*Aspreviously mentioned, the terminals 15 of block it) are fixed solidly through the mounting plane 17 in a predetermined geometric pattern. The terminals 16 of the block 11 are also fixed solidly through the mounting member 19 and so positioned that they will mate with the appropriately paired terminals 15 of the other block '10 when the two blocks-1t) and 11 are mated. However,
two blocks and 11 are mated, the V-shaped chisel point 21 will tend to rotate or align the notch-shaped extremity 24 with it. This rotational displacement causes a resistive torque which tends to rotate the end 24 back to its free position. FIG. 4 shows the end 24 of terminal '16 in its free position in solid lines and shows its mated -rotationally displaced position in dashed lines.
The torque caused by the rotation of the end 24 furnishes the contact force required to insure adequate electrical contact pressure at the contact areas a and b shown in FIG. 6.
It now becomes apparent that the contact force can be controlled and preset by the amount of the reduction or" the cross sectional area portion 26 of the terminals 16.
The contact force is directly proportional to the torque required to'twist' the terminal shank. That torque is in turn proportional to the cross sectional area of the ter- Hence, the contact force generated at contact areas a and b is proportional to the cross sectional area 26 of the terminal 16.
The preferred embodiment of the invention has been shown in FIGS. 1, 2, and 3 With the terminals 16 having the reduced cross sectional area portion 26. This has been done merely to demonstrate theprinciple of the invention and it is contemplated by, the inventor that the terminals may also have a reduced cross sectional area portion in order to adequately preset the torque generated when the terminals 15 and 16 are mated. The amount of the cross sectional area reduction, if any, is determined by the'arnount of contact force desired.
Although the preferred embodiment of the invention contemplates that the electrical contacting extremities 21 and 24 will be V-shaped and complementary, it is obvious that if end 24 was generally concave or U-shaped and end 21 was generally convex or rounded in a relatively large radius, or was rectangular and fit within the U-shaped notch that similar results would be obtained. The V-.
shaped chisel and notched ends were used to simplify the disclosure of the principle used for obtaining the contact force. It is also obvious that the electrical properties of the contacting surfaces can be enhanced by plating or coating them with precious metal such as gold or silver.
Because of the shape of the contacting extremities 21 and 24 of the terminals 15 and 15, and the rotational displacement ofthe terminals 16 with respect to the other terminals 15, the same force that creates the contact torque has a component tending to separate the blocks 10 and 11. In order to prevent the separation, a snap clamp 14, in this instance, is used to hold the blocks 15 and 11 together. The clamp 14 snaps into-an appropriately located indentation 27 in the protective cover 12. The cover 12 has a fastener 28 that clamps onto the incoming cable 13 to prevent the individual wires from being torn from the wire receiving extremities 22, and is secured to block 16) by the screws 29.
Block 11 has not been shown with a cover 12 or incoming cable 13 as it is contemplated that the device might find application where the block 11 is made a part of another piece of apparatus. It is deemed to be well within the capabilities of those familiar with the art to make modifications wherein the device may be fitted with two covers, no covers, different clamps, and various ways of holding the blocks 10 and 11 to auxiliary structures without departing from the essence of the invention.
It will be obvious to those skilled in the art that vari- -ous changes or alterations of the preferred embodiment of the invention shown in the various figures of the drawing can be made, such as changing the means for keeping the blocks'together, using the contacts in structure other than for multiple wire connectors, or changing the physical configurations of the terminals and their mating extremities. However, such changes are obvious and do not depart from the scope of the invention disclosed above and the appended claims.
