Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of in order to connect the electric connector of planar grid array chip module especially.
[background technology]
Along with the integrated application of systems technologies such as multimedia, communication and computer, no matter be desktop computer or mobile computer at present, its function from strength to strength, the circuit design of main frame is also more complicated.
At present, industry generally adopts electric connector to remove to electrically connect chip module to circuit board.It comprises insulating body and is located in plurality of terminals in the body and tin ball and the metal upper casing and the metal lower shell that can flexibly connect mutually, and be used for rocking bar that metal upper casing and metal lower shell are fixed together, wherein insulating body is between metal upper casing and metal lower shell.Can be by the tin ball bonding being connected to the mode of pad on the circuit board, insulating body is fixed on the circuit board, insulating body pressed metal lower casing also is fixed on the circuit board metal lower shell simultaneously, by rocking bar pressed metal upper casing, chip module is fixed in the electric connector again.Like this, just realized being connected of chip module and circuit board.But, because this electric connector is when welding, certain flexural deformation can take place in insulating body and metal lower shell, and insulating body is different with the heat distortion amount of metal lower shell, and it is again to be installed together closely, can cause moving of metal lower shell, appearance can not accurate in locating, thereby can cause bad phenomenon such as not prison welding is solid, thereby make electric connector and the circuit board can not excellent contact, influence its normal electric connection.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[summary of the invention]
The purpose of this utility model is to provide a kind of electric connector, and its welding is good, can realize normal the electric connection.
In order to reach above-mentioned creation purpose, the utility model electric connector, can be installed on the circuit board, comprise insulating body and can accommodate the metal lower shell of insulating body, and be located in plurality of terminals in the insulating body, be provided with the gap between described insulating body and metal lower shell, but move freely in described insulating body and the metal lower shell small range.
Compared with prior art, the utility model electric connector, owing between insulating body and metal lower shell, be provided with the gap, insulating body metal lower shell relatively moves freely, even insulating body diastrophic phenomenon occurs when welding, also can not influence the location of metal lower shell, can make firm welding, guarantee excellent contact between electric connector and the circuit board, realized its normal electric connection.

Fig. 5 is the three-dimensional exploded view of another angle of the utility model electric connector.
[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.
Extremely shown in Figure 5 as Fig. 1, the utility model electric connector 1, can be installed on the circuit board (not icon), be used to accept LGA chip (not icon) (certainly, also can be other chip module or other electron component), it comprises insulating body 10 and is located in plurality of conductive terminals (not shown) and tin ball (not shown), the metal upper casing 12 that can flexibly connect mutually and metal lower shell 13 in the insulating body 10, and is used for rocking bar 14 that metal upper casing 12 and metal lower shell 13 are fixed together.Wherein insulating body 10 is contained between metal upper casing 12 and the metal lower shell 13, and terminal protrudes out insulating body 10 upper surfaces.Rocking bar 14 comprises axle center part 140, and the operating portion 141 that is approximately perpendicular to axle center part 140 reaches from axle center part to projecting inward pressing part 142.But rocking bar 14 pressed metal upper casings 12 are firmly to be fixed on the LGA chip in the electric connector 1.
Insulating body 10 is made up of the insulating material that slightly is square, the LGA chip is placed in wherein, insulating body 10 is provided with some terminal containing slots 11 (the part terminal containing slot only is shown among the figure) of accommodating conducting terminal, and the gulde edge piece 100 above terminal containing slot is arranged around it.Conducting terminal is arranged in this terminal containing slot, and the upper surface by tin ball and circuit board welds together.Six direction is provided with gap 15 to described insulating body 10 reaching up and down all around with metal lower shell 13, described insulating body 10 and metal lower shell 13 all around and up and down six direction can move freely, like this, in the process of welding, even diastrophic phenomenon appears in insulating body 10, also can not influence the location of metal lower shell 13, can make firm welding.In addition, be provided with at least two (in the present embodiment in described metal lower shell 13 with the installing hole 16 of fixing this metal lower shell 13, described metal lower shell is provided with four installing holes), on described metal lower shell 13, also be provided with and pass installing hole 16 (in the present embodiment with the fixture (not shown) of fixing this metal lower shell 13, described fixture is a screw), described fixture passes installing hole l6 and is fixed on the circuit board, so that metal lower shell 13 and circuit board are fixed together, can prevent from the process of motion, to cause the problem of solder joint solder crack like this because of impact shock.
After welding is finished, insulating body 10 just firmly is fixed on the circuit board, insulating body 10 pressed metal lower casings 13 make metal lower shell 13 also be fixed on the circuit board simultaneously, again by rocking bar pressed metal upper casing 12, the LGA chip is fixed in the electric connector 1, like this, just realized the electric connection of LGA chip and circuit board.
The utility model electric connector, owing to be provided with the gap at fore-and-aft direction at insulating body and metal lower shell, insulating body metal lower shell relatively moves freely, even diastrophic phenomenon appears in insulating body when welding, also can not influence the location of metal lower shell, can make firm welding, guarantee excellent contact between electric connector and the circuit board, realize its normal electric connection.
