Abstract

An electrical connector includes a housing and a terminal module mounted in the housing. The terminal module includes an insulative body, a fixed part mounted on the insulative body extending along a back-to-front direction, and a plurality of terminals. The fixed part defines a mounting hole through the fixed part along front-to-back direction. The insulative body has a connecting arm inserting into the mounting hole for position the fixed part on the insulative body. The fixed part defines a pilot hole extending to the mounting hole, and glue is disposed into the pilot hole to bond the fixed part with the insulative body.

Claims

1. An electrical connector comprising:

a housing;

a terminal module mounted in the housing, the terminal module comprising an insulative body, a fixed part mounted on the insulative body extending along a back-to-front direction, and a plurality of terminals, the fixed part defining a mounting hole through the fixed part along front-to-back direction, the insulative body having a connecting arm inserting into and engaging an edge of the mounting hole for positioning the fixed part, the connecting arm having a diversion tank;

wherein

the fixed part defines a pilot hole extending to the mounting hole, and glue is disposed through the pilot hole into the diversion tank to bond the fixed part with the connecting arm of the insulative body; and

the fixed part has a partition arranged around the edge of the mounting hole for preventing the glue from flowing out of the diversion tank.

2. The electrical connector as claimed in claim 1, wherein the connecting arm has a locking barb at an end thereof.

3. The electrical connector as claimed in claim 1, wherein the diversion tank is T-shaped.

4. The electrical connector as claimed in claim 1, wherein a cross section of the mounting hole is quadrilateral, and the partition is a U-shape surrounding three edges of the mounting hole.

5. The electrical connector as claimed in claim 1, wherein the fixed part has a plate extending rearwardly, the terminals mounted on two sides of the plate.

6. The electrical connector as claimed in claim 5, wherein the plate defines a plurality of receiving slots on the two sides, the terminals received in corresponding receiving slots.

7. The electrical connector as claimed in claim 1, wherein the terminal comprises a mating portion forwardly extending beyond the fixed part, a connecting portion received in the receiving slot, and a fixed portion inserted into the fixed part, the fixed portion defining a barb for preventing the terminal from rearwardly disengaging the fixed part.

8. The electrical connector as claimed in claim 1, wherein the insulative body defines a guide post, and the fixed part defines a guide passageway receiving the guide post.

9. An electrical connector comprising:

a terminal module including an insulative body defining therein a plurality of mating holes each extending along a front-to-back direction;

a plurality of contacts each having a mating portion disposed in the corresponding mating hole and a tail portion exposed outside of the corresponding mating hole;

a fixed part forwardly attached to a rear side of the insulative body in said front-to-back direction;

one of said insulative body and said fixed part forming a mounting hole therein in the front-to-back direction, and the other forming a deflectable connecting arm extending along the front-to-back direction to inserted into the mounting hole in the front-to-back direction with thereon a locking barb abutting against said one of said insulative body and said fixed part in said front-to-back direction for securement between the insulative body and the a fixed part in said front-to-back direction; and

a pilot hole formed in one of said insulative body and said fixed part around both said mounting hole and said deflectable connecting arm and exposed to an exterior;

wherein the deflectable connecting arm having a diversion tank;

wherein the fixed part defines the pilot hole extending to the mounting hole, and liquid glue is injected through the pilot hole into the diversion tank to bond the fixed part with the deflectable connecting arm of the insulative body so as to prohibit deflection of the deflectable connecting arm; and

the fixed part has partition arranged around the edge of the mounting hole for preventing the glue from flowing out of the diversion tank.

10. The electrical connector as claimed in claim 9, wherein said linkage extends along a transverse direction perpendicular to said front-to-back direction.

11. The electrical connector as claimed in claim 9, wherein the connecting arm is formed on the insulative body and the mounting hole is formed in the fixed part.

12. The electrical connector as claimed in claim 11, wherein said pilot hole is formed in the fixed part.

13. The electrical connector as claimed in claim 9, wherein said pilot hole extends and is exposed to the exterior in a transverse direction perpendicular to said front-to-back direction.

14. The electrical connector as claimed in claim 9, wherein the fixed part forms a plurality of through hole each dimensioned similar to a cross-section of the tail portion so as to allow the corresponding contact to be inserted therethrough and into the corresponding mating hole.

15. The electrical connector as claimed in claim 14, wherein the tail portion of each of said contacts forms a pair of side protrusions on two opposite side edges to be not only a stopper to abut against a rear face of the fixed part for preventing forward movement of the contact with regard to the fixed part but also a container to cooperate with the planar body of the tail portion for receiving a corresponding wire soldered on the tail portion.

16. The electrical connector as claimed in claim 15, wherein said fixed part forms a plurality of ribs to form corresponding receiving slots each between every adjacent two ribs, and the tail portion of each contacts is disposed in the corresponding receiving slot with said pair of side protrusions intimately located inside of the corresponding ribs.

17. The electrical connector as claimed in claim 9, wherein a partition is formed on said one of said insulative body and said fixed part around said mounting hole to cover the locking barb in a transverse direction perpendicular to said front-to-back direction.

18. The electrical connector as claimed in claim 9, wherein a glue escape slot is formed in the connecting arm facing said mounting hole in a transverse direction perpendicular to said front-to-back direction.
