Abstract
Abstract This electric cable connector for printed wiring cards has an insert spacer at the location where the contacts of the connector are joined to the conductors of the cable and between the upper and lower layers of contacts when the connector is for a doublefaced printed wiring card. The spacer has channels for the individual contacts with the sides of the channels forming barriers between adjacent contacts and providing for convenient soldering of the conductors to the contacts of the connector. The use of shrink tubes is no longer necessary. The connector assembly has a shell or housing that houses the connector body, the spacer and the wires of the electrical cable; and there is a polarizing tongue extending from the housing in position to cooperate with a depression in the handle of a printed wiring card.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
185 words
An electrical cable connector for connecting a generally circular cable, containing a multiplicity of separately insulated conductors, to the edge contacts of printed wiring cards, including in combination a connector body which houses parallel rows of electrical connectors that touch the edge contacts of the wiring card, the connectors having portions that contact with surfaces of the connector body for holding the connectors against displacement with respect to the connector body in the direction of the longitudinal length of said connectors, the ends of the connectors extending beyond the connector body on the side thereof remote from the card, and a spacer with rows of passages in different planes and in which the conductors and the extending ends of the connectors are located and in which the ends of the conductors overlap and connect with the connectors, the spacer having at least a portion of thE length of said passages open at the top, but with side barriers between the passages and substantially narrower than the passages, for access to the extending connectors and the overlapping conductors to connect each connector with its overlapping conductor.
Claim 2
Dependent Claim
185 words

Claim 5
Dependent Claim
79 words
The electrical cable connector described in claim 3 characterized by the openings being in the rearward face of the spacer and being of enlarged diameter at the rearward ends and of reduced diameter toward their forward ends, and the change in diameter is an abutment for insulation on each conductor to limit the extent to which the conductor is inserted into the opening and the resulting overlap of the connector and the end of the conductor beyond said insulation.
Claim 6
Dependent Claim
66 words
The electrical cable connector described in claim 2 characterized by the passages in the spacer being open channels throughout their length with the sides of the channels forming the side barriers between the passages, said side channels being wide enough to receive insulated end portions of the conductors with bare portions of the conductors beyond the insulation for contact with the extending ends of the connectors.
Claim 7
Dependent Claim
35 words
The electrical cable connector described in claim 2 characterized by the spacer being of one piece construction and being held against displacement normal to the planes of said layers of connectors by the connectors themselves.
Claim 8
Dependent Claim
48 words
The electrical cable connector described in claim 2 characterized by the spacer being held against the forward displacement by the connector body and being held against displacement in all other directions by a surrounding shell and by the connectors and the conductors that are connected to said connectors.
Claim 9
Dependent Claim
68 words
The electrical cable connector described in claim 1 characterized by the spacer including the barriers thereof being made of plastic material that can withstand the heat of molten solder used to join the connectors to the conductors, and the depth of the passages being greater than the combined heights of a bare end portion of one of the conductors and an extending end of one of the connectors.
Claim 10
Dependent Claim
25 words
The electrical cable connector described in claim 8 characterized by the spacer being made of white polytetrafluoroethylene for reflecting heat of an infra-red soldering operation.
Claim 11
Dependent Claim
79 words
The electrical cable connector described in claim 1 characterized by the connector assembly comprising sections that connect together to form a shell that houses the connector body, the spacer and the end portions of the conductors, and that clamps the cable which includes said conductors, one section of the shell having a tongue that extends through a cutout section in a handle of the wiring card, with which the connector is intended to be used, for polarizing the connector.
