A cap and connector device is provided having a great facility in assembly and disassembly for wiring. The rapid assembly is accomplished by separating two halves of the device, namely, a wire terminal portion and a cable clamping portion by removal of fastener members which extend through the wire clamp into the cable clamp portion. The fasteners employed in this device are essentially fastener type devices which have threads set at an acute angle to the fastener axis. The fasteners are also provided with a slotted head to permit use as screws. The separation or unscrewing of the fasteners is accomplished very rapidly because of the acute thread angle, and the parts are thus taken apart very quickly. After the attachment of the cable conductors to the connector terminals has been performed, the two parts are again assembled, and in this case, the fasteners permit a very rapid tightening of the two parts together. In addition, a problem of stripping the threads in the plastic portion of the connector is overcome. |

DETAILED DESCRIPTION I claim: 1.
A connector comprising a cable termination having a first insulating plastic housing having an outer wall portion and containing electrical contacts and wire terminals for connection of the wires of the cable which is held in a clamp part of said connector, a cable clamp including a second insulating plastic housing having a cable opening therethrough, said clamp including means for securing said second housing to a cable passing therethrough, said cable termination including a set of peripheral unthreaded fastener ports extending through the outer wall portion of said first insulating housing, and extending through the length of the first housing generally parallel to the axis of the first housing, said cable clamp having a set of unthreaded fastener sockets extending into the second insulated housing thereof at outer wall locations matching and aligned with the outer wall locations at which fastener ports are located in the first insulating cable terminal housing, and fasteners extending through said fastener ports of said first housing into said fastener sockets of said second housing and holding said cable termination housing and said cable clamp housing together, said fasteners having slotted heads to receive tools to apply torque to said fasteners and said fasteners having a non-threaded shank and a threaded end portion with the thread aligned at a lead angle which is steep relative to the lead angles of less than 10.
degree.
