专利汇可以提供Apparatus for compression and coldwelding of stripped ends of multi-conductor cable专利检索，专利查询，专利分析的服务。并且This disclosure is directed to a method and means for compression and coldwelding of stripped ends of flat, insulated, multi-conductor cable, the conductors of which are usually, but not always, composed of stranded, soft, annealed copper. The stripped or bared ends of the resulting cable are spaced apart within very close tolerances of the order of 1/100 of an inch. These close tolerances are obtained by first stripping a small area of the cable along a designated stripping line to bare a given area of conductors, then confining the bare conductors within grooves or channels of a first metal die shoe having predetermined center-to-center spacings, and compressing the conductors under pressure exerted by means of a second metal die shoe carrying teeth interfitting into, or slidably engaging with, each of the grooves occupied by the conductors. After compression and coldwelding of the conductors this disclosure provides a simplified, and automatic, method and means of precisely cutting the compressed ends. The stripped, compressed conductor ends are then fluxed and tinned so that they are very rigidly fixed in place with respect to each other, and can be much more readily interconnected to various types of precisely spaced termination points and other electrical interconnect assemblies.，下面是Apparatus for compression and coldwelding of stripped ends of multi-conductor cable专利的具体信息内容。
1. An apparatus for the simultaneous compression of a plurality of stripped conductors aligned in generally parallel relationship, which comprises: a female die member having a plurality of grooves formed therein, each of said grooves having a predetermined spacing with respect to each other and having dimensions such that the walls of each of said grooves confine each of said stripped conductors to be compressed, when said stripped conductors to be compressed are viewed in cross-section; a male die member having a plurality of teeth affixed thereto, said teeth having a predetermined spacing and dimensions corresponding to that of said grooves whereby each of said teeth is adapted to substantially interfit within each of said grooves of said female die member; and compression means for forcibly moving the teeth of said male die member, along a fixed path relative to said female die member, and into the grooves of said female die member whereby to compress strIpped conductors confined within said grooves.
2. The apparatus of claim 1 which includes means for finely adjusting the position of said female die member relative to said male die member whereby to obtain accurate, interfitting of said teeth within said grooves.
3. The apparatus of claim 1 which includes means for finely adjusting the position of said male die member, relative to said female die member whereby to obtain accurate interfitting of said teeth within said grooves.
4. The apparatus of claim 1 wherein each of said grooves have entrances which are enlarged for easy entry of said teeth.
5. The apparatus of claim 1 which includes a die block having a top surface, said female die member being stably mounted to said die block so that the bottom of said grooves lie substantially flush with said top surface of said die block.
6. The apparatus of claim 1 wherein said compression means includes: an arm member; means for attaching said male die member to said arm member; a first adjustment means for finely adjusting the position of said male die member relative to said female die member whereby to obtain accurate interfitting of said teeth with said grooves; and a motion limiting means attached to said arm member and abutting said male die member preventing upward movement of said male die member as said teeth of said male die member interfit within the grooves of said female die member.
7. The apparatus of claim 6 which includes a second adjustment means for said motion limiting means.
8. The apparatus of claim 6 wherein said second adjustment means comprises a pair of adjustment screws.
9. The apparatus of claim 1 wherein said compression means includes an arm member, said male die member being removably attached to said arm member, and actuating means for moving said arm member and said attached male die member into engagement with said female die member.
10. The apparatus of claim 1 which includes: a cutting tool movably mounted adjacent the teeth of said male die member; and extension means on said cutting tool, said compression means engaging said extension means, and causing movement of said cutting tool from a rest position to a cutting position immediately after said teeth of said male die member have moved into said grooves of said female die member and compressed said stripped conductors confined within said grooves.
11. The apparatus of claim 10 wherein said extension means is finely adjustable with respect to said compression means.
12. The apparatus of claim 10 which includes a first spring means urging said cutting tool to a position immediately adjacent the teeth of said male die member.
13. The apparatus of claim 10 which includes a spring means urging said cutting tool to said rest position remote from said cutting position.
14. The apparatus of claim 5 which includes means for removably mounting said female die member to said die block.
15. The apparatus of claim 6 wherein said means for attaching said male die means to said arm member is readily removable.
16. An apparatus for the simultaneous compression of a plurality of stripped conductors aligned in generally parallel relationship, which comprises: a female die member having a plurality of grooves formed therein, each of said grooves having a predetermined spacing with respect to each other and having dimensions such that the walls of each of said grooves confine each of said stripped conductors to be compressed, when said stripped conductors to be compressed are viewed in cross-section; a die block having a top surface, said female die member being stably mounted to said die block so that the bottom of said grooves lie approximately level with said top surface of said die block; an arm member mounted for movement along a fixed path; a male die member having a plurality of teeth affixed thereto, said teeth having a predetermined spacing and dimensions corresponding to that of said grooves whereby each of saId teeth is adapted to substantially interfit within each of said grooves of said female die member; means for attaching said male die member to said arm member; and means for moving said arm member towards said female die member along said fixed path whereby said teeth of said male die member are forcibly moved into the grooves of said female die member to compress stripped conductors confined within said grooves.
17. The apparatus of claim 1 which includes means for finely adjusting the position of said female die member relative to said male die member whereby to obtain slidable engagement of said teeth within said grooves.
18. The apparatus of claim 16 which includes means for finely adjusting the position of said male die member, relative to said female die member whereby to obtain slidable engagement of said teeth within said grooves.
19. The apparatus of claim 16 which includes a first adjustment means for finely adjusting the position of said male die member relative to said female die member whereby to facilitate slidable engagement of said teeth within said grooves.
20. The apparatus of claim 19 which includes a motion limiting means attached to said arm member and abutting said male die member preventing upward movement of said male die member as said teeth of said male die member slidably engages within the grooves of said female die member.
21. The apparatus of claim 20 which includes a second adjustment means for said motion limiting means.
22. The apparatus of claim 16 which includes: a cutting tool movably mounted adjacent the teeth of said male die member; and extension means on said cutting tool, said compression means engaging said extension means and causing movement of said cutting tool from a rest position to a cutting position immediately after said teeth of said male die member have moved into said grooves of said female die member and compressed said stripped conductors confined within said grooves.
23. The apparatus of claim 22 wherein said extension means is finely adjustable with respect to said compression means.
24. The apparatus of claim 22 which includes a first spring means urging said cutting tool to a position immediately adjacent the teeth of said male die member.
25. The apparatus of claim 22 which includes a spring means urging said cutting tool to said rest position remote from said cutting position.
