## Abstract

An electrical connector for electrically connecting a mating element to a motherboard includes an insulating body having two side surfaces disposed symmetrically, at least one rotating shaft protruding from the side surface, a casing including at least one side portion corresponding to the side surface, and at least one protruding block. The side portion of the casing extends backward to form a rotating portion. The rotating portion is disposed with an elongated hole. A distance between an edge of the elongated hole and an edge of the rotating portion is substantially a fixed value. A distance between the protruding block and the rotating shaft is equal to or slightly larger than the fixed value. The rotating shaft urges against the edge of the elongated hole of the casing, and the protruding block urges against the edge of the rotating portion of the casing.

## Claims

### Claim 1

An electrical connector, for electrically connecting a mating element to a motherboard, comprising:
(a) an insulating body, having two side surfaces disposed symmetrically;
(b) at least one rotating shaft, protruding from the side surface and located at a rear end of the side surface;
(c) a casing, comprising at least one side portion corresponding to the side surface, wherein the side portion extends backward to form a rotating portion, the rotating portion is disposed with an elongated hole, and a distance between an edge of the elongated hole and an edge of the rotating portion is substantially a fixed value; and
(d) at least one protruding block, wherein a distance between the protruding block and the rotating shaft is equal to or slightly larger than the fixed value, the rotating shaft urges against the edge of the elongated hole, and the protruding block urges against the edge of the rotating portion, so that the rotating shaft and the protruding block jointly limit a trajectory of movement or rotation of the casing.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, wherein the insulating body and the protruding block are integrally formed.

### Claim 3 (depends on 1)

The electrical connector according to claim 1, wherein at least one stopping portion is disposed to limit an angle of rotation of the casing.

### Claim 4 (depends on 1)

The electrical connector according to claim 1, wherein the rotating shaft is formed by stamping a plate, and the plate has a catch portion for being fixed to the insulating body.

### Claim 5 (depends on 1)

The electrical connector according to claim 1, wherein two sides of the insulating body are disposed with at least one narrow slot formed through an upper surface and a bottom surface of the insulating body.

### Claim 6 (depends on 5)

The electrical connector according to claim 5, wherein at least one iron sheet is fixed in the narrow slot by an interference fit, and the iron sheet is fixed to the motherboard.

### Claim 7 (depends on 6)

The electrical connector according to claim 6, wherein the iron sheet is disposed with a soldering portion, and the soldering portion is fixed to the motherboard by soldering.

### Claim 8 (depends on 1)

The electrical connector according to claim 1, wherein a rear end of at least one side of the insulating body is disposed with a boss corresponding to the rotating portion.

### Claim 9 (depends on 8)

The electrical connector according to claim 8, wherein a front end of the boss is disposed with a first chamfer.

### Claim 10 (depends on 8)

The electrical connector according to claim 8, wherein a rear end of the boss is disposed with a second chamfer.
