Abstract

An electrical connector (100) includes a connector member (1) providing a plurality of conductive terminals (10) therein, an insulative coat (3) defining a receiving cavity (30) with an opening and a pair of through holes (32) provided at opposite sides of the receiving cavity, a pair of latching members received in the receiving cavity with a front hook portion extending out of the opening, and a pair of press members (4). The connector member includes a base portion (18) received in the receiving cavity (30) and a mating portion (14) extending forward from the base portion and out of the opening. The press members are assembled into the through hole and are retained with a back portion of the latching member.

Claims

1. An electrical connector, comprising:

a connector member providing a plurality of conductive terminals therein, comprising a base portion and a mating portion extending forward from the base portion;

an insulative coat defining a receiving cavity with an opening and a pair of through holes provided at opposite sides of the receiving cavity, the base portion of the connector member being received in the receiving cavity and the mating portion extending out of the opening;

a pair of latching members received in the receiving cavity with a front hook portion extending out of the opening; and

a pair of press members;

wherein the press members are assembled into the through holes and retained with a back portion of the latching member.

2. The electrical connector as described in claim 1, wherein the insulative coat is one single-piece.

3. The electrical connector as described in claim 1, wherein the electrical connector further comprises a retaining member retained between the insulative coat and the connector member, the base portion is retained in the retaining member and the mating portion extends out of the opening.

4. The electrical connector as described in claim 1, wherein the electrical connector further comprises a cable connecting with the connector member, the insulative coat comprises a cable outlet to let the cable pass through.

5. The electrical connector as described in claim 1, wherein the connector member comprises a shell with two sidewalls, each sidewall defines a latching arm extending forward from a front end thereof and a retaining portion to retain with the press member.

6. The electrical connector as described in claim 1, wherein the connector member comprises a shell with two sidewall, each sidewall defines a latching arm extending forward from a front end thereof and a bend portion extending outwards from the bottom edge to retain with the press member.

7. The electrical connector as described in claim 5, wherein each through hole defines a stopper engaging with the inside edge of the press member to preventing the press member from further entering into the cavity.

8. The electrical connector as described in claim 5, wherein the retaining portion is provided with a hole, the press member comprises two locking portions retained into the hole.

9. The electrical connector as described in claim 6, wherein the press member defines a slot corresponding the bend portion, the press member retained in the sidewall by the bend portion engaging with the slot.

10. The electrical connector as described in claim 8, wherein the press member defines two contacting portions beside the locking portions, which can jundied the sidewall.

11. An electrical connector comprising:

an insulative housing;

a plurality of contacts disposed in the housing;

a metallic shell covering at least one face of the housing and unitarily forming a pair of deflectable latches on two sides thereof; and

a coat overmolded upon a rear portion of the housing;

wherein

the coat defines a pair of through holes on two sides thereof, and a pair of pressing member are laterally inwardly attached to the corresponding latches, respectively, after the coat is applied to the housing.

12. The electrical connector as claimed in claim 11, wherein a retaining member encloses a front portion of the housing so as to limit outward lateral movement of the latches, and said retaining member is assembled to the coat.
