Abstract

An electrical connector includes an insulating housing, a plurality of electrical terminals, an inner shield housing and an outer shield housing, the outer shielding is designed in a two-piece type and has a first shield member and a second shield member. The first shield member has a first resilient tab forwardly extending therefrom and the second shield member has a wing tab disposed therein, so as to the first resilient tab and the wing tab will not interfere with each other for the wing tab going with the outer shield housing, the electrical connector can be disposed in a recess on an edge of the PCB such that the electrical connector includes a portion thereof that is located above an outer surface of the PCB and another portion that is located below the outer surface of the PCB.

Claims

1. An electrical connector capable of being applied to a PCB for engaging with a mating connector, the electrical connector comprising:

an insulating housing;

a plurality of electrical terminals within the insulating housing, each of the electrical terminals including a contact portion for electrically engaging with the mating connector and a tail portion extending from the insulating housing for electrically engaging with the PCB;

an inner shield housing including a first cavity formed therein and covering the insulating housing; and

an outer shield housing having a first shield member, the first shield member having a top wall and side walls extending from opposing sides of the top wall, a second shield member combining with the first shield member integrally, the second shield member having a top wall and side walls extending from opposing sides of the top wall, the outer shield housing forming a second cavity between the first shield member and the second shield member, wherein the first shield member has a first resilient tab forwardly extending from and connecting with each of two sidewalls thereof, the second shield member has a recess formed on each of two sidewalls thereof and relating to the first resilient tab for containing the first resilient tab into the recess, and a wing tab folded from a rim around the recess.

2. The electrical connector of claim 1, wherein the PCB includes a recess at an edge thereof, the connector being received within the recess of the PCB in such a manner that the electrical connector includes a portion that is both above an outer surface of the PCB and another portion that is below the outer surface of the PCB.

3. The electrical connector of claim 1, wherein the wing tab is received within an aperture located in the PCB at a location other than the edge of the PCB.

4. The electrical connector of claim 1, wherein the insulating housing includes a base, a first mating plate and a second mating plate parallel arranged and both extending forwardly from the base, electrical terminals being located on both the first mating plate and the second mating plate.

5. The electrical connector of claim 1, wherein the contact portions of the electrical terminals are located on a bottom surface of the first mating plate and a top surface of the second mating plate.

6. The electrical connector of claim 1, wherein the inner shield housing includes two opposing sidewalls arranged straight vertically and parallel, and a top wall and a bottom wall both disposed horizontally and connecting the two opposing sidewalls;

the top wall defines a rear wall downwardly extending and connecting a 5 rear end thereof, the two opposing sidewalls each has a second resilient tabs disposed thereon.

7. The electrical connector of claim 1, wherein the first shield member has a clamping slot formed in a front end thereof, the second shield member has a clamping tab disposed on an end portion thereof, which the clamping tab relates to and engages with the clamping slot.

8. The electrical connector of claim 1, wherein the first shield member has a buckling protrusion arranged thereon, the second shield member has a buckling slot formed thereon, which the buckling slot relates to and engages with the buckling protrusion.

9. The electrical connector of claim 1, wherein the wing tab is folded from an upper portion or a lower portion of the rim around the recess.

10. The electrical connector of claim 1, wherein the wing tab has an insertion portion, which is downwardly or upwardly extended from thereof, connecting on an end thereof, the PCB has an insertion aperture relating to the insertion portion of the wing tab and formed thereon for the insertion portion engaging with the insertion aperture.

11. The electrical connector of claim 1, wherein the wing tab connectively solders on the PCB.
