## Abstract

An electrical connector includes an insulating housing, a shell retained on the insulating housing, a plurality of terminals retained on the mating portion of the insulating housing, and a spacer engaging with the insulating housing. The insulating housing includes a base portion and a mating portion protruding from the base portion, the base portion has a top wall, a bottom wall, a pair of sidewalls connecting with the top wall and bottom wall, a front wall connecting with the mating portion and a rear wall. The front wall of the base portion has a pair of slanted portions formed on two sides of the mating portion, the rear wall of the base portion has a plurality of barriers for retaining the terminals and a pair of flange portions on two sides of the barriers, each flange portion has a groove on an inner side surface to engage with the spacer.

## Claims

### Claim 1

An electrical connector, comprising:
an insulating housing including a base portion and a mating portion protruding from said base portion, said base portion including a top wall, a bottom wall, a pair of sidewalls connecting with said top wall and bottom wall, a front wall connecting with said mating portion and a rear wall;
a shell retained on said insulating housing;
a spacer engaging with said rear wall of the insulating housing;
a plurality of terminals retained on said mating portion of said insulating housing;
wherein said front wall of the base portion has a pair of slanted portions formed on two sides of said mating portion, said rear wall of the base portion has a plurality of barriers for retaining said terminals and a pair of flange portions on two sides of said barriers, each flange portion has a groove on an inner side surface to engage with said spacer;
wherein said bottom wall of the base portion defines a pair of inserting slots for retaining said shell, said rear wall of the base portion has a pair of step portions engaging with said shell; and
wherein said base portion has a pair of engaging slots formed on said top wall and a protruding portion formed on an end of said engaging slots, said engaging slots extend into said protruding portion.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, wherein said protruding portion extends perpendicular to the engaging slots and protrudes upwardly from said top wall, said protruding portion is formed on a rear side edge of said top wall.

### Claim 3 (depends on 2)

The electrical connector according to claim 2, wherein said shell has a top plate which includes a pair of elastic tabs and a pair of locking tabs formed on a backside of said elastic tabs, said locking tabs engage into said protruding portion along said engaging slots.

### Claim 4 (depends on 3)

The electrical connector according to claim 3, wherein said shell has a side plate and a retaining portion bended backwardly from a front edge of the side plate, said retaining portion has a vertical portion and a horizontal portion bended from a bottom edge of said vertical portion, said vertical portion is parallel to an outer surface of said side plate and includes an opening.

### Claim 5 (depends on 4)

The electrical connector according to claim 4, wherein said side plate of the shell has a hole corresponding to said opening of the side plate and a bending tab inside the hole.

### Claim 6 (depends on 5)

The electrical connector according to claim 5, wherein said shell has a pair of bending legs retained on said step portions of the insulating housing.

### Claim 7 (depends on 6)

The electrical connector according to claim 6, wherein said bottom wall further has a pair of locking posts.
