Abstract
ABSTRACT
An electrical connector for terminating a flat multi-conductor electrical cable (100), comprises a body member (1) carrying on each of two opposite surfaces a row of terminals (2) and a bus member (5), and two cover members (7, 8) covering the two surfaces respectively. The surfaces of the body member (1) are formed with grooves (9) which receive conductors (101) of the cable (100) and guide them from mouths (11) of the grooves (9) at an edge of the body member (1), to the terminals (2) and bus member (5). The mouths (11) are formed to guide the conductors (101) over the two surfaces of the body member (1) as required.

Description
S
`~
This invention relates to an electrical connector for terminating a flat multi-conductor electrical cable.
In French Patent Specification FR-A-2066671 which issued on July 12, 1971 to AMP Incorporated, there is described such a connector comprising a body member of electrically insulating material carrying on each of two OppOSite surfaces a row of electrical terminals each having a mating portion adjacent one edge of the body member and a conductor-connection portion adapted to establish an electrical connection to a conductor of a flat multi-conductor cable, surfaces of the body member being formed with grooves to receive the conductors of the cable and direct the conductors to the conductor-connection portions of the terminals.
This known connector suffers from the disadvantage that since the grooves are in two distinct groups on opposite sides of a projecting plate member of the connector body, and since the conductors in a flat multi-conductor cable are generally in a spaced parallel co-planar array, it is necessary to prepare an end of a cable to be connected to the connector by baring end portions of the conductors of the cable and then separating the conductors into two arrays in parallel planes for receipt on the grooves in the two sides of the plate member of the connector ~0 body, respectively. Such preparation of the cable end is a time consuming and costly operation.
In the connector disclosed in German Patent Specification V~5 DE-A-1947355 which was published on April 23, 1970, in the na~e of AMP
Incorporated the difficulty of cable end preparation is overcome by the provision of two clamping members which when clamped about the exposed conductors at an end of a cable urge the conductors from their initial planar array into two arrays in spaced parallel planes as required, the two clamping members being received in a further body member to complete the connector.
This known connector suffers from the disadvantage that the body is formed from a plurality of separate parts which must be separately manufactured, and must be assembled on a cable end, both these operations being time consuming and costly.
According to the present invention there is provided an electrical connector for terminating a flat multi-conductor electrical cable, com-prising a body member of electrically insulating material carrying on each of two opposite surfaces a row of electrical terminals each having a mating portion adjacent one edge of the body member surface and a conductor-connection portion adapted to establish an electrical connection to a conductor of a flat multi-conductor electrical cable, surfaces of the body member being formed with grooves to receive the conductors of the ~0 cable and direct the conductors of the conductor-connection portions to the terminals, characterised in that the conductor-receiving grooves open to an edge of the body member by way of a straight row of funnel entry mouths each defined by three converging walls, the base walls of the mouths being arranged with some on each side of the central longi-tudinal plane of the body member such that conductors inserted into the mouths as a planar array will be guided to one or the other surface of the body member.
The connector of ~his invention has the advantage that the only single piece body member serves both to carry the terminals~ and also to locate the conductors of a cable in the ccnductor-receiving grooves as required, without any separation of the conductors into two groups prior to application of the connector being necessary.
Further, only the body member is a relatively complex structure, it being possible for the cover members to have smooth surfaces and thus be easy to manufacture.
This invention will now be described by way of example with reference to the drawings, in which:
Figure 1 is a perspective view of an assembled connector accor-ding to the invention with a cable connected thereto and positioned over ~0 a contact-post-carrying substrate with which the connector is to be mnted;

Claims (7)
1. An electrical connector for terminating a flat multi-conductor electrical cable, comprising a body member of electrically insulating material carrying on each of two opposite surfaces a row of electrical terminals each having a mating portion adjacent one edge of the body member surface and a conductor-connection portion adapted to establish an electrical connection to a conductor of a flat multi-conductor electrical cable, surfaces of the body member being formed with grooves to receive the conductors of the cable and direct the conductors of the conductor-connection portions to the terminals, characterised in that the conductor-receiving grooves open to an edge of the body member by way of a straight row of funnel entry mouths each defined by three converging walls, the base walls of the mouths being arranged with some on each side of the central longitudinal plane of the body member such that conductors inserted into the mouths as a planar array will be guided to one or the other surface of the body member.
2. A connector as claimed in claim 1, characterised in that adjacent the position where it opens into the mouth each groove is formed at each edge with an upstanding ridge which, after insertion of a conductor into the groove, is turned in over the conductor to retain the conductor in the groove.
3. A connector as claimed in claim 1, including two cover members adapted to be positioned over respective body member surfaces, thereby to close the grooves therein characterised in that the cover members are each formed at the mating end of the connector with a row of projecting teeth arranged and adapted to engage in apertures in the body member to secure the cover members to the body member at that end.
4. A connector as claimed in claim 3, characterised in that at the cable exit end of the connector each cover member is formed at one side with a latch arm having at its free end an inwardly directed projection arranged and adapted to engage in a recess in the other cover member thereby to latch the cover members together over the body member.
5. A connector as claimed in claim 3, characterised in that each cover member carries on its inner surface a row of stop members which after latching of the cover members to the body member are located behind the mating portions of the terminals.
6. A connector as claimed in claim 1, including two cover members adapted to be positioned over respective body member surfaces, thereby to close the grooves therein, characterised in that at the cable exit end of the connector each cover member is formed at one side with a projection and at the other side with a correspondingly shaped recess arranged and adapted to receive the projection of the other cover member with a cable located between the projec-tions and recesses whereby on latching of the cover members to the body mem-ber the cable is distorted in two directions.
7. A connector as claimed in claim 6, characterised in that the projections are of tapered V-shape.
