Abstract

An improved plug connector including a housing and a housing cover engaged to each other in a length direction i.e. axial direction of the plug. Since the engaging portion is not provided in the width direction of the plug, the dimension in the width direction of the plug connector can be reduced. The improved plug collector may include a plurality of grooves for fitting terminals formed in the axial direction of the housing, the terminals being covered by portion of the housing cover such that the plurality of grooves are closed at each end. As such, the resin used to overmold the housing/housing cover is prevented from flowing to the front end of the plug connector by way of the grooves. The improved plug connector may also include a shield case having a clamp portion that is made eccentric from the axis core of the shield case. Since the clamp portion is not provided in the axial direction of the shield case, the clamp portion does not prevent and/or hinder the housing from being easily inserted into the shield case. As such, the integration of the housing with the shield case is simplified.

Claims

1. A plug connector, comprising:

a housing;

a plurality of grooves formed in an axial direction of the housing;

a plurality of terminals fitted in the grooves, the terminals being capable of being terminated to a cable;

a housing cover for covering a portion of the cable and the terminals;

an intersecting portion formed at the housing and orthogonal to the grooves; and

an engaging projection formed at the housing cover for engaging with the intersecting portion in the axial direction.

2. The plug connector of claim 1, wherein the intersecting portion includes a rectangular bridge member extending from the housing to form a bridge over the plurality of grooves, and the engaging projection is fitted in a space formed between the plurality of grooves and the rectangular bridge member.

3. The plug connector of claim 2, wherein the space portion is a through hole extending through both ends of the bridge member, the through hole being open in the axial direction.

4. The plug connector of claims 3, wherein the engaging projection is at least a pair of projections formed at positions respectively substantially closing the openings at both ends of the bridge member.

5. The plug connector of claim 2, wherein the rectangular bridge member includes a plurality of walls partitioning the space portion in accordance with the number of the grooves;

and

wherein the engaging projection is a plurality of small projections respectively fitted in openings of small gaps formed by the plurality of partition walls.

6. The plug connector of claim 2, wherein the rectangular bridge member includes a plurality of walls partitioning the space portion in accordance with the number of the grooves.

7. The plug connector of claim 1, including a shield case, the shield case including a main body for shielding the housing.

8. The plug connector of claim 7, wherein the shield case includes a clamp portion provided eccentrically from the shield case main body and having a clamp portion capable of clamping a cable terminated to the terminals.

9. A plug connector and cable assembly, comprising:

a housing;

a plurality of grooves formed in an axial direction of the housing;

a plurality of terminals fitted in the grooves, the terminals being terminated to a cable;

a housing cover for covering a portion of the cable and the terminals;

an intersecting portion formed at the housing and orthogonal to the grooves; and

an engaging projection formed at the housing cover for engaging with the intersecting portion in the axial direction.

10. The plug connector and cable assembly of claim 9, including a shield case, the shield case including a main body for shielding the housing.

11. The plug connector and cable assembly of claim 10, wherein the shield case includes a clamp portion provided eccentrically from the shield case main body and having a clamp portion capable of clamping a cable terminated to the terminals.

12. A connector shield case, the shield case comprising:

a shield case main body for shielding a housing having a plurality of terminals; and

a clamp portion provided eccentrically from the shield case main body and having a clamp portion capable of clamping a cable terminated to the terminals.
