Abstract

The invention relates to an electric connector used for connecting a chip module to a printed circuit board electrically. The electric connector comprises an insulation body accommodating a plurality of conductive terminals, a driver arranged on the insulation body and capable of moving up and down relative to the insulation body, and a press claw arranged on the insulation body and capable of pressing and fixing a chip in a preset position under the driving of a driving claw, wherein the press claw is provided with a plurality of bulges in a protruding way, and the chip module is pressed and connected by the bulges in a point contact mode. Since the press claw contacts with the chip module in a point contact mode, burrs at the edges of the press claw can be effectively prevented from scratching the chip module during the molding of the press claw.

[background technology]

Existing a kind of electric connector that is used for the test chip module; The driving body that comprises the insulating body that is installed with plurality of conductive terminals (not shown) substantially, is located on the insulating body and can moves up and down with respect to insulating body and be installed on the insulating body can open and make position between the crimping claw that moves; Crimping claw can be crimped on the chip module, guarantees that excellent electrical property is connected between chip module and conducting terminal.The edge of paw is that face contacts or the line way of contact with the chip module, when the levelness at edge is not high enough, its can not with the pressing closely of chip module, directly have influence on the quality that contacts between chip module and conducting terminal; In addition, the easy scratch chip of the burr module of paw edge generation.

[summary of the invention]

Technical problem to be solved by this invention is: a kind of electric connector is provided, and it has the paw structure of protection chip module.

For solving the problems of the technologies described above; The present invention provides a kind of electric connector; Be used to electrically connect the chip module to printed circuit board (PCB); The driving body that comprises the insulating body that contains plurality of conductive terminals, is located on the insulating body and can moves at above-below direction with respect to insulating body and be installed on insulating body and can be driven aforementioned chip is pushed the crimping claw that is fixed in the precalculated position by driving claw; Said crimping claw protrudes out and is provided with some convexities, between protruding and the chip module with a mode crimping chip module that contacts.

Compared to prior art, the present invention's crimping claw edge protrudes out the bulge-structure that is provided with, and makes crimping claw with the mode and the dies groups of contact of a contact, thereby has effectively avoided when the crimping claw moulding, the burr scratch chip module that its edge produces.

[embodiment]

See also Fig. 1 to Fig. 4; A kind of electric connector 200; It can be used for chip module 40 is tested, the driving body 20 that comprises the insulating body 10 that is installed with plurality of conductive terminals (not shown), is located on the insulating body 10 and can moves up and down with respect to insulating body 10 and be installed on insulating body 10 both sides respectively and can open and make position between the crimping claw 30 that moves.

Insulating body 10 is square substantially, and it is enclosed by four sidewalls 11 and forms, and the outside of sidewall 11 is provided with some guide channels 14.Insulating body respectively is provided with one first cylinder 12 on 10 4 corners, and these first cylinders 12 can be inserted in the corresponding fixing hole (not shown) of printed circuit board (PCB) (not shown), so that this electric connector 200 is fixed on the printed circuit board (PCB).Be provided with mating holes 13 with first cylinder, 12 opposite sides on the insulating body 10, be provided with spring (not shown) in the mating holes 13.Insulating body 10 bottoms also are provided with insulation board 16, and insulation board 16 is provided with some terminal holes that run through 18 and is used to accommodate conducting terminal.

Driving body 20 also is square, and it can move up and down with respect to insulating body 10.Driving body respectively is provided with second cylinder 22 on 20 4 corners, and this second cylinder 22 can be inserted in the mating holes 13 of insulating body 10.Driving body 20 overhangs towards insulating body 10 and is provided with the guide element 24 corresponding with guide channel 14, and guide element 24 guide channel 14 relatively slides, the two cooperation can guarantee driving body 20 relatively insulating body 10 accurate moving and do not produce deflection.

See also Fig. 3-5, the opposite side of insulating body 10 is pivoted with a crimping claw 30 respectively, and this crimping claw 30 is provided with an

arc edge

31, and 31 protrudes out and be provided with some protrudingly 311 from the edge, and crimping claw 30 is through protruding 311 crimping chip modules 40.Said protruding 311 is curved semicircle shape, and it coats the arc edge 31 of crimping claw 30, crimping claw 31 protruding 311 protrude out the bearing of trend of direction perpendicular to crimping claw 30 edges 31.In the present embodiment, the edge 31 of crimping claw 30 is continuous curved surface.In another embodiment, the edge 31 ' of crimping claw 30 ' is discontinuous curved surface, and it is provided with a middle opening 300 ' the edge is divided into discontinuous first and second portion, and aforementioned protruding 311 ' protrudes out from first, second part respectively.

See also illustrated in figures 1 and 2ly, when driving body 20 being applied a downward pressure and make second cylinder 22 be inserted in the mating holes 13 fully, spring is in compressive state, and this moment, crimping claw 30 was in opening, can chip module 40 be placed on the insulation board 16.Please consult shown in Figure 4 simultaneously; After driving body 20 applied pressures were eliminated, driving body 20 can receive the elastic force of spring and move up, when moving to the extreme higher position; Crimping claw 30 is in closure state; At this moment, its two convexities 31 are pressed on the chip module 40, guarantee that excellent electrical property is connected between chip module 40 and conducting terminal.
