Abstract

An electrical connector and the buckle assembly thereof. The buckle assembly includes a stiffener provided with a frame opening for receiving an insulating body of the electrical connector, and a load plate with a rear end pivoted to the stiffener. The stiffener has a reinforce rib in front of the frame opening. The reinforce rib has a raised portion protruding upward from an upper surface of the stiffener, and an extending portion is formed by horizontally extending from the raised portion. The load plate has a through hole for receiving the chip module, a receiving hole in front of the through hole, and two receiving holes behind the through hole. Each receiving hole allows a locking member to pass therethrough to fix the load plate onto the stiffener.

First claim

What is claimed is:

1. A buckle assembly for fixing a chip module to a socket, comprising:
a stiffener provided with a frame opening for receiving the socket, wherein the stiffener has a reinforce rib in front of the frame opening, the reinforce rib has a raised portion protruding upward from an upper surface of the stiffener, and an extending portion is formed by horizontally extending from the raised portion; and
a load plate with a rear end pivoted to the stiffener, the load plate being provided with a through hole for receiving the chip module, a receiving hole in front of the through hole, and two receiving holes behind the through hole, wherein each receiving hole allows a locking member to pass therethrough to fix the load plate onto the stiffener, wherein:
the socket comprises: an insulating body and a plurality of terminals received in the insulating body;
the stiffener is provided with a first pivoting portion and a second pivoting portion which are located on a same side of the insulating body, the first pivoting portion is located between the second pivoting portion and the insulating body;
a rear end of the load plate is pivoted to the second pivoting portion;
a guide frame is pivoted to the first pivoting portion, the guide frame has four edges defining an opening for receiving the chip module;
two sliding rails are respectively provided on two opposite sides of the opening, for carrying two side plates of a clamping member, and the two side plates are slidable along the two sliding rails; and
the clamping member is used for fixing the chip module.

2. The buckle assembly of claim 1 , wherein when the clamping member is assembled on the guide frame and the guide frame moves towards a closing direction to be installed on the insulating body, the sliding rails are located on two opposite sides of the insulating body and located between the stiffener and the side plates, and an upper surface of each of the sliding rails is not higher than an upper surface of the insulating body.

3. The buckle assembly of claim 1 , wherein a first stopping portion is formed by extending upward from each of the sliding rails to be stopped to a side edge of corresponding one of the side plates, a second stopping portion is formed by extending horizontally from each of the first stopping portion, a front end of each of the first stopping portion is flush with a front end of corresponding one of the sliding rails, a groove is concavely disposed from an upper surface of the side plate, the second stopping portion is stopped above the groove, and the second stopping portion is not higher than the upper surface of the side plate.

4. The buckle assembly of claim 3 , wherein the front end of each of the second stopping portion is not flush with the front end of corresponding one of the sliding rails.

5. The buckle assembly of claim 3 , wherein a front end of each of the second stopping portions has a guide surface for guiding the clamping member to be assembled to the guide frame.

6. The buckle assembly of claim 1 , wherein the insulating body has a concave portion, the guide frame has a hook portion corresponding to the concave portion, and the hook portion cooperates with the concave portion to buckle the guide frame to the insulating body.

7. The buckle assembly of claim 6 , wherein the insulating body has a positioning slot, the concave portion is located in front of the positioning slot, the clamping member has a positioning portion corresponding to the positioning slot, and when the clamping member is assembled on the guide frame and the guide frame moves towards a closing direction to be installed on the insulating body, the positioning portion first cooperates with the positioning slot to position the clamping member and then the hook portion cooperates with the concave portion to buckle the guide frame to the insulating body.

8. The buckle assembly of claim 1 , wherein the guide member comprises a plastic member and a metal member insert molded to the plastic member, the plastic member has two opposite side arms and a rear arm connected to the two side arms, the side arms are provided with the sliding rails.

9. The buckle assembly of claim 8 , wherein the rear arm is pivoted to the first pivoting portion.

10. The buckle assembly of claim 8 , wherein the metal member is provided with two opposite first arms, and a second arm and a third arm connected to the two first arms, the first arms are insert molded into the side arms and the first arms go beyond the side arms along their length directions, the second arm is insert molded into the rear arm, and the third arm bends downward from the first arms to reserve the clamping member when the clamping member is installed to the guide member.

11. The buckle assembly of claim 10 , wherein the stiffener is provided with a reserved slot to receive the third arm.

12. The buckle assembly of claim 1 , wherein the load plate is provided with a bending portion pivoted to the stiffener, and a projection protruding backward at each of the two opposite sides of the bending portion, wherein each of the two projections is provided with the receiving hole.

13. The buckle assembly of claim 1 , wherein a grasping portion protrudes forward from the clamping member, and the grasping portion is provided with a perforation located below the receiving hole for the locking member to pass through.

14. The buckle assembly of claim 1 , wherein the stiffener comprises a bottom plate and a metal sheet fixed onto the bottom plate, the metal sheet is provided with a pivoting portion pivoted to the load plate, and the reinforce rib is disposed on the bottom plate.

15. An electrical connector for electrically connecting a chip module, comprising:
an insulating body;
a plurality of terminals received in the insulating body, for electrically connecting the chip module;
a stiffener provided with a frame opening for receiving the insulating body and a reinforce rib in front of the frame opening, wherein the reinforce rib has a raised portion protruding upward from an upper surface of the stiffener, and an extending portion formed by extending horizontally from the raised portion; and
a load plate with a rear end pivoted to the stiffener, the load plate being provided with a through hole for receiving the chip module, a receiving hole in front of the through hole, and two receiving holes behind the through hole, wherein each receiving hole allows a locking member to pass therethrough to fix the load plate onto the stiffener, wherein:
the stiffener is provided with a first pivoting portion and a second pivoting portion which are located on a same side of the insulating body, the first pivoting portion is located between the second pivoting portion and the insulating body;
a rear end of the load plate is pivoted to the second pivoting portion;
a guide frame is pivoted to the first pivoting portion, the guide frame has four edges defining an opening for receiving the chip module;
