BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates to an electrical connector, and particularly to a CPU (Central Processing Unit) socket with rotation mechanism which can be easily and conveniently assembled to the seat.

2. Description of Related Arts

China Utility Patent No. CN205452718 claiming the priority of a US Provisional Application No. 62/185,036 filed on Jun. 26, 2015m discloses a CPU socket with a rotation mechanism at either end. Anyhow, such a rotation mechanism, which is used to urge either the CPU carrier or the pressing load plate to be in an vertical open state, includes plural parts requiring to be individually assembled to the corresponding tiny holding section of the seat inconveniently and disadvantageously.

An improved structure for assembling the rotation mechanism in an easy way, is desired.

SUMMARY OF THE DISCLOSURE

An object of the invention is to provide an electrical connector for receiving a CPU, having a rotation mechanism which has a simplified structure and is easy to be assembled to the seat frame. The electrical connector includes a connection main part surrounded by the seat frame, and a CPU carrier for carrying the CPU and a load plate for downwardly pressing the CPU respectively pivotally located at two opposite ends of the seat frame in the front-to-back direction. A set of rotation mechanism is rotatably assembled upon one end to receive the CPU carrier. A pair of supporting arms are unitarily formed with one end of the seat frame, forming a pair of locking recesses having one open side. The rotation mechanism includes a main body, a pivot assembled upon the main body, and a torsion spring assembled upon the pivot. The seat frame includes a stopper opposite to the pair of locking recesses in the lengthwise direction. The rotation mechanism is pre-assembled as one piece and successively assembled upon the seat frame along the lengthwise direction with the pivot engaged within the pair of locking recesses and a middle section of the torsion spring engaged with the stopper.

The main body of the rotation mechanism is insulative, and two ends of the torsion spring are retained within the main body. The torsion spring urges the rotation mechanism toward an upstanding position

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
