Abstract

An electrical connector includes an insulating body, a plurality of terminals integrated in the insulating body, a strengthening structure and a shell mounted around the insulating body. The insulating body has a base portion and a tongue portion extending forward from a front face of the base portion. A top face of the tongue portion is concaved downward to form a receiving groove passing through a front end of the tongue portion. The strengthening structure has a base plate and two holding arms which oppositely extend from two opposite side edges of a rear of the base plate. A front edge of the base plate is bent downward to form a protecting eave. The base plate is molded in the receiving groove of the tongue portion and the holding arms are embedded in the base portion. The front end of the tongue portion is wrapped by the protecting eave.

Claims

1. An electrical connector, comprising:

an insulating body having a base portion and a tongue portion extending forward from a front face of the base portion, a top face of the tongue portion being concaved downward to form a receiving groove passing through a front end of the tongue portion;

a plurality of terminals integrated in the insulating body;

a strengthening structure having a base plate and a pair of holding arms which oppositely extend from two opposite side edges of a rear of the base plate, a front edge of the base plate being bent downward to form a protecting eave, the base plate being molded in the receiving groove of the tongue portion of the insulating body and the holding arms being embedded in the base portion, the front end of the tongue portion being wrapped by the protecting eave; and

a shell being mounted around the insulating body.

2. The electrical connector as claimed in claim 1, wherein two opposite ends of the protecting eave of the strengthening structure further protrude sideward to form a pair of protecting ears, a pair of side walls is formed at two sides of the receiving groove of the insulating body, front ends of the side walls are wrapped by the protecting ears of the strengthening structure.

3. The electrical connector as claimed in claim 1, wherein a plurality of through holes is vertically opened in the tongue portion of the insulating body, a bottom side of the receiving groove protrudes upward to form a plurality of buckling frames encircling the through holes respectively, a plurality of buckling holes is apart opened in the base plate of the strengthening structure, the buckling frames are buckled in the buckling holes respectively.

4. The electrical connector as claimed in claim 3, wherein two opposite side edges of the base plate are concaved inward to form a pair of fixing gaps, a pair of side walls is formed at two sides of the receiving groove of the insulating body with a pair of fixing blocks protruding inward thereon, the fixing blocks are snapped in the corresponding fixing gaps.

5. The electrical connector as claimed in claim 3, wherein a front end of the bottom side of the receiving groove protrudes upward and then is bent rearward to from two buckling portions, two buckling apertures are apart opened across the front edge of the base plate, the buckling portions are buckled in the buckling apertures respectively.

6. The electrical connector as claimed in claim 1, wherein the shell has a top plate, two side plates and a bottom plate connected together, bottom edges of the side plates protrude downward to form two first fixing feet, two ends of a rear edge of the top plate are bent and extend downward to form two second fixing feet, two face-to-face edges of the second fixing feet extend towards each other to form a pair of blocking boards which are blocked behind the insulating body.
