Abstract

An electrical connector is used for being connected with a chip module and comprises a base, a bearing plate, a driving part and a fastening part. A plurality of conducting terminals are assembled on the base, the bearing plate is assembled on the base and used for bearing the chip module, the driving part is assembled on the base and can move up and down, and the fastening part is driven by the driving part and can be clamped on the chip module. The conducting terminals penetrate through the bearing plate to be connected with the chip module, and the base is provided with an abutted block which is located below the fastening part and can prevent the fastening part from being pressed excessively.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that is used for connecting a chip module on the circuit board that is installed on.

[technical background]

Chip module is connected to printed circuit board (PCB) through electric connector usually, and wherein electric connector is soldered on the circuit board.United States Patent (USP) the 6th, 768, disclosed a kind of electric connector that is used for connecting chip module for No. 563, it comprises that one is used for carrying the pedestal of chip module, the drive plate that can move up and down in the pedestal top, but the motion of drive plate driver card fastener makes its pinning or discharges chip module.When pressing down drive plate, fastener upwarps, and can be placed into chip module on the pedestal or with chip module this moment takes out from connector.When discharging drive plate, drive plate pops up under spring action, and fastener presses down simultaneously, chip module can be pinned.In addition, drive plate is provided with the fairlead that extends in all around downwards, offers guide channel on the guiding block, and pedestal is provided with the projection that is arranged in guide channel.

In the electric connector of prior art described above, for preventing that drive plate from excessively upwarping and then the fastener that causes excessively presses down, the projection of pedestal and the guide channel of drive plate cooperatively interact and carry out spacing to drive plate.Though this design can suppress fastener to a certain extent to excessively the pressing down of chip module, the fairlead intensity of drive plate is lower, when stressed big or may cause the damage of product or cause drive plate to come off from pedestal when being subjected to force unbalance.

Therefore, necessary existing electric connector is improved to overcome the defective of prior art.

[utility model content]

The purpose of this utility model is to provide a kind of can effectively prevent the electric connector that fastener excessively presses down.

The utility model electric connector is achieved through the following technical solutions: a kind of electric connector, be used to connect a chip module, it comprises the pedestal that is assembled with plurality of conductive terminals, is assembled in the loading plate that is used to accept chip module on the pedestal, the actuator that is assembled in the pedestal top and can moves up and down, and be subjected to the driving of actuator and can be fastened in fastener on the chip module, conducting terminal passes loading plate and is connected with chip module, wherein pedestal is provided with the holding block that is positioned at the fastener below, can prevent that fastener from excessively pressing down.

Compared to prior art, the utility model electric connector is provided with holding block in the fastener below, can prevent that fastener from excessively pressing down.

[embodiment]

Fig. 1 and Fig. 2 are respectively the stereogram of the utility model electric connector 1 when being in closed and opening.In the lump with reference to the exploded view of electric connector among Fig. 31, the utility model electric connector 1 is used to connect a chip module 9, it comprises a pedestal 2, be assembled in the loading plate 5 that is used to accept chip module 9 on the pedestal 2, the actuator 3 that is assembled in pedestal 2 tops and can moves up and down, and is subjected to the driving of actuator 3 and can be fastened in fastener 6 on the chip module 9.Plurality of conductive terminals 4 is assembled in the pedestal 2 and passes loading plate 5 and be connected with chip module 9.

Be provided with spring 7 between actuator 3 and the pedestal 2, the recovery campaign after being used for actuator 3 and pressing down.Actuator 3 respectively passes a bolt 8 in its place, four angles, and an end of bolt 8 is locked to pedestal 2.The guide function that moved up and down of 8 pairs of actuators 3 of bolt also can prevent excessively upward bullets of actuator 3.When actuator 3 was in pressed status, it compressed spring 7, and the head of bolt 8 is protruding to the top of the upper surface of actuator 3.

Fastener 6 is connected respectively to pedestal 2 and actuator 3 by two rotating shafts 60,61.When actuator 3 presses down, upwards upset of fastener 6, can put into chip module 9 on the loading plate 5 or with chip module 9 and remove from loading plate 5 this moment; And when actuator 3 moved upward, fastener 6 upset downwards also can be pressed on the chip module 9.Fastener 6 is provided with and protrudes out with the contact site 62 of crimping chip module 9 downwards and be positioned at the bottom surface 63 at contact site 62 rears.

Pedestal 2 respectively is provided with a holding block 20 in the below of fastener 6.With reference to Fig. 4 and Fig. 5, holding block 20 is shaped on the pedestal 2 in the lump, also is assembled on the pedestal 2 after the moulding separately.Loading plate 5 respectively is provided with a breach 50 corresponding to holding block 20 places, passes for holding block 20.Emphasis is with reference to Fig. 5, and when fastener 6 was in normal pressed status, its contact site 62 was crimped on the chip module 9.Holding block 20 is positioned at 63 belows, bottom surface of fastener 6, but does not contact with bottom surface 63, has certain clearance between the two.When electric connector 1 something unexpected happened such as spring 7 elasticity excessive and when actuator 3 pushed away on excessively, may cause fastener 6 excessively to press down chip module 9, this moment, holding block 20 can be butted on the bottom surface 63 of fastener 6, thereby alleviated the downforce of 6 pairs of chip modules 9 of fastener.And for example, when part deforms, also may cause fastener 6 excessively to press down, this moment, holding block 20 can be butted on the fastener 6 equally.
