Abstract

An electrical connector (1) is adapted for mounting to a circuit substrate having a metallic shell (2) assembled onto an insulated housing (3). The metallic shell (2) has a base portion with two side-walls (23) and a pair of arms (24) extending from the side-walls (23). Some interferential tabs (243) are introverted on both of the arms (24) and corresponding slots (311) are formed on the insulated housing (3). When assembling, the interferential tabs (243) are engaged with corresponding slots (311) to firmly fit the metallic shell (2) and insulated housing (3) together.

Claims

1. An electrical connector, comprising:

a metallic shell having a base portion defining a first receiving space therein, and a pair of arms extending from the base portion and defining a second receiving space therebeween;

a insulated housing assembled in the second receiving space;

a plurality of terminals received in said insulated housing; and

interferential arrangement between the metallic shell and the insulated housing, and including a tab extending from the arm and a slot defined in the insulated housing and in which the tab interferential engaged with the slot.

2. The electrical connector as claimed in claim 1, wherein said interference tab is introverted from said arms.

3. The electrical connector as claimed in claim 2, wherein said insulated housing defines a side-face, said slot is a vertical slot hollowed from the top-face and opening with the side-face.

4. The electrical connector as claimed in claim 3, wherein said interference tab is on the free end of said arm.

5. The electrical connector as claimed in claim 4, wherein each of said arms near the base portion defines a through hole and a projection defined on said side-face to lock with said through hole.

6. The electrical connector as claimed in claim 5, wherein a protruding bar is formed between the interference tab and the through hole.

7. The electrical connector as claimed in claim 5, wherein and a elastic board lock is formed on the first receiving space.

8. An electrical connector adapted for mounting to a circuit substrate, comprising:

an insulated housing comprising a top-face and a pair of side-faces, vertical slots defined on said side-faces;

a plurality of terminals received in said insulated housing;

a metal shell assembled onto said insulated housing, comprising a top-wall, a pair of side-walls linked by the top-wall and a pair of arms extending rearward from said side-walls, interference tab introverted from each of said arms, and vertical slot formed on the insulated housing to hold the tab.

9. The electrical connector as claimed in claim 8, wherein said vertical slot is hollowed from the top-face and opening with corresponding side-face.

10. The electrical connector as claimed in claim 9, wherein said interference tab is on the free end of the arm.

11. The electrical connector as claimed in claim 10, wherein said top-wall and two side-walls defining a base portion, each of said arms near the base portion defines a through hole and a projection defined on said side-face to lock with said through hole.

12. The electrical connector as claimed in claim 11, wherein a protruding bar is formed between the interference tab and the through hole.

13. An electrical connector comprising:

an insulative housing defining a mating port exposed to an exterior through a front mating face, and two side faces rearwardly extending from two opposite sides of the front mating face;

a metallic shell assembled to the housing and including an upside down U-shaped main body including a top wall and two side walls and located in front of the front mating face of the housing under a condition that said top wall of said main body is higher than the housing;

a spring member unitarily extending rearwardly from a rear edge of the top wall toward the housing; and

a pair of extension arms unitarily extending rearwardly from rear edges of said two opposite side walls of the main body;

wherein

fastening means is formed on the extension arm and the corresponding side face for fastening the extension arm and the corresponding side face together under a condition that said fastening means is configured to only allow assembling between the shell and the housing in a vertical direction.
