## Abstract

An electrical connector includes an insulating body having a plurality of receiving slots and a plurality of terminals respectively fixed in the insulating body. Each of the terminals has a base at least partially disposed in the receiving slot, at least one contact arm, a first fixing portion and an extending arm extending laterally from the base, and a second fixing portion. The first fixing portion fastens the insulating body. A soldering portion is disposed on the extending arm. The second fixing portion selectively extends from the extending arm or the soldering portion and fastens the insulating body. A distance between the second fixing portion and the soldering portion is shorter than that between the first fixing portion and the soldering portion.

## Claims

### Claim 1

An electrical connector, comprising:
(a) an insulating body, provided with a plurality of receiving slots; and
(b) a plurality of terminals, respectively fixed in the insulating body, each of the terminals having a base at least partially disposed in the receiving slot, at least one contact arm, a first fixing portion and an extending arm extending laterally from the base, and a second fixing portion, wherein the first fixing portion fastens the insulating body, a soldering portion is disposed on the extending arm, the second fixing portion selectively extends from the extending arm or the soldering portion and fastens the insulating body, and a distance between the second fixing portion and the soldering portion is shorter than that between the first fixing portion and the soldering portion.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, wherein a guide groove connected with the receiving slot is formed at a bottom of the insulating body corresponding to the extending arm, and the extending arm is received in the guide groove.

### Claim 3 (depends on 2)

The electrical connector according to claim 2, wherein a first fixing hole is formed from the receiving slot from back to front to match and fix the first fixing portion, and a second fixing hole is formed from the guide groove from back to front to match and fix the second fixing portion.

### Claim 4 (depends on 3)

The electrical connector according to claim 3, wherein an inner wall of the second fixing hole is formed with at least one first chamfer gradually shrinking from an opening towards the inside of the second fixing hole, and the first chamfer correspondingly matches a second chamfer disposed on the second fixing portion.

### Claim 5 (depends on 4)

The electrical connector according to claim 4, wherein an acute angle exists between the second fixing portion and the soldering portion, the second chamfer is located on an upper surface of the second fixing portion, and the first chamfer is disposed in the second fixing hole corresponding to the second chamfer.

### Claim 6 (depends on 4)

The electrical connector according to claim 4, wherein the first chamfer and the second chamfer conform to and contact each other.

### Claim 7 (depends on 1)

The electrical connector according to claim 1, wherein the second fixing portion is located above the soldering portion and parallel to the soldering portion.

### Claim 8 (depends on 1)

The electrical connector according to claim 1, wherein the first fixing portion and the extending arm extend in the same direction.

### Claim 9 (depends on 1)

The electrical connector according to claim 1, wherein the insulating body has a protruding block located between and contacting the second fixing portion and the soldering portion.

### Claim 10 (depends on 1)

The electrical connector according to claim 1, wherein the second fixing portion is disposed to extend from an extending direction of the extending arm, and the soldering portion is bent and extends downwards from the extending arm.
