Abstract

The utility model discloses an electrical connector assembly which is used for the electrical connection between a CPU and a circuit board. The electrical connector assembly comprises a connector body storing a plurality of conductive terminals, and a clamping assembly. The clamping assembly comprises a frame for storing the connector body, a clamping member pivoted to one end of the frame and adapted to rotation, and a driver arranged on the frame. The driver is formed by a curved rod provided with a bent portion, and a pusher rod substantially vertical to the curved rod. A fixed block is arranged on one end of the frame and provided thereon with an elongated storage groove for storing the curved rod of the driver. Meanwhile, the frame is further provided with a tongue-like positioning elastic sheet. The elastic sheet is positioned near to the fixed block in a way that one end thereof is fixed on the frame and the free end thereof extends towards the curved rod of the driver and is suspended from the curved rod. When the electrical connector assembly is in opened state, the elastic sheet, under the elastic action, can allow the curved rod to locate in the lowest position of the storage groove, thereby ensuring effective connection of the electrical connector assembly.

[embodiment]

A kind of electrical connector module 1, be to be used to LGA central processing unit (not icon) is electrically connected and is retained on the circuit board (not icon), see also Fig. 3 and Fig. 4, it comprises the lamellar connector body 2 and the fastening assembly of accommodating plurality of conductive terminals (not icon).Fastening assembly comprise ccontaining connector 2 rectangle framework 3, be hinged on rectangle framework 3 one ends and the fastener 4 that can rotate relative to framework and the actuator 5 that is installed in the rectangle framework 3 relative other ends and can fastens with fastener 4 around hinged limit.

Actuator 5 is made up of with the push rod 52 vertical with curved bar 51 cardinal principles the curved bar 51 that is provided with kink 511.The residing position of axis runout curved bar 51 axis of this kink 511 and vertical substantially with push rod.

Fastener 4 away from hinged limit freely be provided with buckling parts 41, this buckling parts 41 extends to form and which is provided with groove 411 forward by the edge of free margins, this groove 411 can partly be accommodated the kink 511 of actuator 5.

The centre position of rectangle framework 3 forms the roughly hollow bulb of rectangular shaped, and it can be in order to ccontaining connector 2.One end of this rectangle framework 3 is provided with the structure that can be hinged with fastener 4, its corresponding other end then is provided with the fixed block 31 of two space certain distances, this fixed block 31 is provided with long and narrow bar shaped accepting groove 311, the curved bar 51 of actuator 5 can pass this accepting groove 311 places between two fixed blocks 31 its kink 511, at this moment, push rod 52 is in side outside the rectangle framework 3, and this push rod 52 can be by swinging in and vertical range parallel with rectangle framework 3 under the external force effect.In addition, this rectangle framework 3 is respectively equipped with the Location resilient piece 32 of ligule at the inner side near two fixed blocks 31, these shell fragment 32 1 ends are fixed on the rectangle framework 3 and the other end is suspended on actuator 5 curved bars 51, and this shell fragment 32 is smooth arc surface towards the surface 321 of curved bar 51.

Please cooperate and consult Fig. 5 and Fig. 6, when electrical connector module 1 is in opening, be in the extreme lower position of accepting groove 311 as curved bar 51, strain or elastic deformation amount's minimum do not take place in shell fragment 32; When being in other position as curved bar 51, bigger strain takes place for shell fragment 32 will produce one along the downward active force of accepting groove 311, this active force makes curved bar 51 slide along accepting groove 311 downwards and arrives the extreme lower position of this accepting groove 311, therefore can only be in the extreme lower position of accepting groove 311 by shell fragment 32 curved bars 51, thereby when promotion push rod 52 drive curved bars 51 continue to slide arrival accepting groove 311 extreme higher positions in accepting groove 311, thereby kink 511 can rotate to curved bar 51 under replace in the bottom surface of groove 411, just can finish that fastener 4 is fastened on the framework 3 and then the LGA central processing unit is retained on operation on the connector.
