Abstract

An electrical connector includes an insulative housing (2), a plurality of terminals (3) received in the insulative housing (2) and a shielding shell (4) covering the insulative housing. The insulative housing (2) includes a mating opening (24) extending along a longitudinal direction and a pair of grooves (231) extending with an angle to the mating opening and opening to an exterior. The shielding shell is provided with two shielding shell (41), (42) attached to an outer periphery of the insulative housing (2), which their ends are received and retained in the grooves (231).

Claims

1. An electrical connector comprising:

an insulative housing comprising a pair of side walls and a pair of end walls connecting with the side wall and a mating opening defined between the side walls;

a groove defined at an each corner of one said side wall with the end walls;

a plurality of terminals, each the terminal defining a retaining arm secured in the insulative housing, an engaging portion protruding towards the mating opening and a soldering portion extending outwards from; and

a shielding shell covering the insulative housing, comprising a first shielding shell and a second shielding shell, the two shielding shells comprising a pair of bending portions at opposite ends thereof respectively;

wherein the bending portions of the two shielding shells at the same end of the shell are commonly received and retained in one corresponding groove.

2. The electrical connector as described in claim 1, wherein the grooves extend with an angle to the mating opening and communicate with an exterior surface.

3. The electrical connector as described in claim 1, wherein the grooves open upwards and downwards.

4. The electrical connector as described in claim 2, wherein the bending portions in one groove engage with each other, and each bending portion interfere with a corresponding inner face of the groove.

5. The electrical connector as described in claim 1, wherein the first shielding shell comprises a longitudinal first body portion and a pair of extending portions bending from ends of the first body portion and covering an outside of end walls, said bending portions bend inwards from ends of the extending portions with an predetermined angle for receiving in the grooves.

6. The electrical connector as described in claim 2, wherein the first shielding shell and the second shell comprise a plurality of retaining portions retained in the insulative housing and a plurality of secured tails extending outwards for soldering.

7. The electrical connector as described in claim 2, wherein the insulative housing comprises a pair of guiding holes communicating with the mating opening, one of the side walls adjacent to the guiding holes is thicker than the other side wall.

8. The electrical connector as described in claim 1, wherein the insulative housing comprises a pair of guiding holes communicating with the mating opening, and the guiding holes are larger than the mating opening in a traverse direction.

9. An electrical connector comprising:

an insulative housing having a mating opening extending along a longitudinal direction and a pair of grooves extending with an angle to the mating opening and opening to an exterior;

a plurality of terminals received in the insulative housing; and

a shielding shell comprising two shielding shell attached to an outer periphery of the insulative housing, ends of the two shielding shells being received and retained in two groove.

10. The electrical connector as described in claim 9, wherein the two shielding shells comprise a pair of bending portions at opposite ends thereof respectively, the bending portions at the same end is secured in one groove.

11. An electrical connector comprising:

an insulative housing defining a mating port exposed to an exterior in a first direction and surrounded by a circumferential wall;

a plurality of contacts disposed in the housing with contacting sections exposed in the mating port;

a retention slit formed in the circumferential wall and extending inwardly in an oblique direction from an exterior surface of the circumferential wall; and

at least one metallic shell covering at least a portion of said circumferential wall;

wherein

said shell defines an engagement tab received in said retention slit to hold said shell in position with regard to the housing.

12. The electrical connector as claimed in claim 11, wherein said retention slit is essentially located at a corner of the circumferential wall.

13. The electrical connector as claimed in claim 11, wherein another metallic shell covers other portions of the circumferential wall while with another engagement tab received in said retention slit.

14. The electrical connector as claimed in claim 13, wherein said another shell is longer than said shell.

15. The electrical connector as claimed in claim 14, wherein the longer shell has the corresponding shorter engagement tab than the shorter shell.

16. The electrical connector as claimed inc claim 11, wherein said circumferential wall defines two longitudinal exterior surfaces and two transverse exterior surfaces perpendicular to each other, and said retention slit is oblique to both said longitudinal exterior surfaces and said transverse surfaces.

17. The electrical connector as claimed in claim 11, wherein said engagement unitarily extends from the corresponding shell with an acute angle.
