Abstract

An electrical connector includes an insulative housing defining a mating slot, an inner metallic shield covering the insulative housing, and an outer metallic shield enclosing the insulative housing. The insulative housing includes a first wall, a second wall and two side walls. The inner metallic shield includes a main plate attached to the first wall and two side portions attached to the two side walls. The outer metallic shield includes a main plate located on the outer side of the main plate and two plates attached to the side portions respectively. The insulative housing is provided with grooves on the second walls. The plate is provided with a hook portion fixed in the groove. The two side portions engage the two plates.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative housing comprising a first wall and a second wall spaced from and parallel with each other and two side walls connecting with opposite ends of the first wall and the second wall and defining a mating slot between the first wall and the second wall and opening forwards;
a plurality of contacts arranged on the insulative housing and comprising contacting sections extending into the mating slot; and
an outer metallic shield enclosing the insulative housing and comprising a main plate located on an outer side of the first wall while separated from the first wall by a distance and a pair of side plates fittingly attached to outer sides of the side walls, respectively;
wherein the insulative housing has a groove extending forwardly at each end of the second wall proximal to a corresponding side wall, and each of the side plates comprises a first hook portion bending inward and fittingly retained in the corresponding groove on the second wall;
wherein the first hook portion comprises a bent portion bending inward from a bottom edge of the side plate and a vertical portion bending from the bent portion towards the first wall, the bent portion straddles the second wall, and the vertical portion is fixed in the groove;
wherein a part of the second wall between the groove and the outer side of a corresponding side wall is cut off partially to accommodate the bent portion; and
wherein each of the side plates comprises a second hook portion behind the first hook portion, and the second hook portions are fittingly retained in the groove and backwardly abut against the insulative housing.

2. The electrical connector as claimed in claim 1 , wherein the main plate comprises a partitioning plate and an abutting plate behind the partitioning plate, the partitioning plate is separated from the first wall, the abutting plate comprises an inclined portion extending rearwards from the partitioning plate and a limiting portion extending rearward from the inclined portion, and the limiting portion is attached to an outer side of the first wall and limits a movement of the main plate in a front and rear direction.

3. The electrical connector as claimed in claim 2 , wherein the first wall is recessed from the outer side thereof to form a first stepped surface facing forwards and a second stepped surface facing rearwards, the limiting portion is accommodated in the recess and abuts against the first stepped surface backward, and the limiting portion defines protruding tabs extending forward and forwardly abutting against the second stepped surface.

4. The electrical connector as claimed in claim 3 , wherein the first wall defines a hole penetrating through the first wall in a thickness direction of the first wall, the contacts are fixed to an insulative block, the insulative block defines a holding protrusion protruding into the hole, and the holding protrusion backwardly abuts against an inner surface of the hole.

5. The electrical connector as claimed in claim 4 , wherein the second stepped surface is formed on the inner surface of the hole.

6. The electrical connector as claimed in claim 1 , further comprising an inner metallic shield, and wherein the inner metallic shield comprises a main portion fittingly attached to the outer side of the first wall and side portions at two opposite ends of the main portion, the outer metallic shield comprises a resistant tab bending inwards from the side plate and pressing forward against a notch defined on the main portion of the inner metallic shield.

7. An electrical connector comprising:
an insulative housing comprising a first wall and a second wall extending in a longitudinal direction and two side walls connecting opposite longitudinal ends of the first wall and second wall and defining a longitudinal mating slot opening forward between the first wall and second wall;
a plurality of contacts arranged on the insulative housing;
an inner metallic shield comprising a main portion fittingly attached to an outer surface of the first wall and two side portions bending from the main portion and attached to an outer surface of the side walls;
an outer metallic shield comprising a main plate located on an outer side of the first wall and defining a gap between the main portion of the inner metallic shield and the main plate, two side plates bending from the main plate and attached to the outer surface of the side wall respectively, the side portions of the inner metallic shield sandwiched between the side walls and the side plate of the outer metallic shield;
wherein one of the side portion of the inner metallic shield and the side plate of the outer metallic shield is provided with a protrusion, and the other is provided with a recess to receive and hold the protrusion.

8. The electrical connector as claimed in claim 7 , wherein the side portion comprises an arm extending from two opposite longitudinal ends of the main portion and a clamping end bending from the arm towards the mating slot, and the clamping end is fittingly retained in a cutout defined on the side wall.

9. The electrical connector as claimed in claim 8 , wherein the cutout penetrates the side wall and communicates with the mating slot along the longitudinal direction.

10. The electrical connector as claimed in claim 7 , wherein the outer metallic shield comprises a longitudinal plate attached to the outer surface of the second wall.

11. An electrical connector comprising:
an insulative housing comprising a first wall and a second wall spaced from and parallel with each other and two side walls connecting with opposite ends of the first wall and the second wall and defining a mating slot between the first wall and the second wall and opening forwards;
a plurality of contacts arranged on the insulative housing and comprising contacting sections extending into the mating slot; and
an outer metallic shield enclosing the insulative housing and comprising a main plate located on an outer side of the first wall while separated from the first wall by a distance and a pair of side plates fittingly attached to outer sides of the side walls, respectively;
wherein the insulative housing has a groove extending forwardly at each end of the second wall proximal to a corresponding side wall, and each of the side plates comprises a first hook portion bending inward and fittingly retained in the corresponding groove on the second wall;
wherein the main plate comprises a partitioning plate and an abutting plate behind the partitioning plate, the partitioning plate is separated from the first wall, the abutting plate comprises an inclined portion extending rearwards from the partitioning plate and a limiting portion extending rearward from the inclined portion, and the limiting portion is attached to an outer side of the first wall to limit a movement of the main plate in a front and rear direction; and
wherein the first wall is recessed from the outer side thereof to form a first stepped surface facing forwards and a second stepped surface facing rearwards, the limiting portion is accommodated in the recess and abuts against the first stepped surface backward, and the limiting portion defines protruding tabs extending forward and forwardly to abut against the second stepped surface.

12. The electrical connector as claimed in claim 11 , wherein the first hook portion comprises a bent portion bending inward from a bottom edge of the side plate and a vertical portion bending from the bent portion towards the first wall, the bent portion straddles the second wall, and the vertical portion is fixed in the groove.
