Abstract

An electrical connector comprises a housing assembly and an outer shell surrounding the housing assembly, the housing assembly comprises a first terminal module and a second terminal module; the first terminal module comprises a first body and a group of first terminals fixed to the first body, the first body has a first tongue; the second terminal module comprises a second body and a group of second terminals fixed to the second body, the second body has a second tongue; the first body and the second body oppose each other and are fixed together by at least one engagement column in the first tongue that is locked to at least one locking hole in the second tongue.

First claim

What is claimed is:

1. An electrical connector, comprising;
a housing assembly;
an outer shell surrounding the housing assembly and forming a mating cavity, wherein the housing assembly comprises a first terminal module and a second terminal module, the first terminal module comprising a first body and a group of first terminals fixed to the first body, the first body having a first main body and a first tongue extending forwardly from the first main body, the group of first terminals being exposed to a first mating surface of the first tongue;
the second terminal module comprising a second body and a group of second terminals fixed to the second body, the second body having a second main body and a second tongue extending forwardly from the second main body, the group of second terminals being exposed to a second mating surface of the second tongue;
a grounding plate supported by the first body and the second body and positioned between the group of first terminals and the group of second terminals, wherein the first body and the second body oppose each other and are fixed together and the first tongue is provided with at least one engagement column protruding from the first tongue toward the second tongue and the second tongue being provided with at least one locking hole passing through along a thickness direction of the second tongue, wherein the at least one engagement column is positioned in the at least one locking hole and is stamped so that the first tongue and the second tongue are engaged together.

2. The electrical connector according to claim 1 , wherein the at least one engagement column is provided at a position close to a front end of the first tongue, the grounding plate is formed with a receiving void at a position corresponding to the at least one engagement column.

3. The electrical connector according to claim 1 , wherein after the at least one engagement column is positioned in the at least one locking hole.

4. The electrical connector according to claim 3 , wherein the locking hole is formed with an expanded portion at a side end close to the second mating surface, the expanded portion is used to receive a locking flange formed by an end of the engagement column.

5. The electrical connector according to claim 4 , wherein these second terminals are divided into a plurality of anterior position second terminals and a plurality of posterior position second terminals according to arrangement of these second terminals on the second tongue and the locking holes are positioned in front of these posterior position second terminals and positioned between these anterior position second terminals.

6. The electrical connector according to claims 4 , wherein each engagement column comprises a body portion which is cylindrical and a plurality of protruding ribs protruding from an outer periphery of the body portion, these protruding ribs and the locking hole are tightly engaged with each other.

7. The electrical connector according to claim 1 , wherein the second body is formed with a plurality of positioning columns protruding from an engagement surface opposing the first body and the grounding plate is formed with a receiving channel at a position corresponding to these positioning columns, these positioning columns pass through the receiving channel so as to assure a position of the grounding plate, these positioning columns respectively are further formed with a plurality of dot-like protrusions at top ends of these positioning columns for engaging with the first body with ultrasonic welding.

8. The electrical connector according to claim 1 , wherein each side of the outer shell is formed with a first grounding leg extending downwardly therefrom, each side of the grounding plate is formed with a second grounding leg extending downwardly therefrom, two second grounding legs respectively abut against two inner sides of two first grounding legs.

9. The electrical connector according to claim 1 , wherein the first main body is further provided with at least one insertion column protruding toward the second main body, the insertion column comprises a body portion and at least one protruding rib protruding from an outer periphery of the body portion and the second main body is correspondingly provided with at least one positioning hole, the at least one insertion column is inserted into the at least one positioning hole.

10. The electrical connector according to claim 1 , wherein the grounding plate is a separate member interposed between the first terminal module and the second terminal module, the grounding plate comprises a base plate positioned between the first tongue and the second tongue and at least one grounding leg bent outwardly from the base plate.
