Abstract
A kind of electric connector, comprise the insulating body, plurality of conductive terminals and the corresponding scolder that is attached at conducting terminal that are provided with the terminal accommodation hole, the zone that terminal and scolder attach is provided with scaling powder, compared with prior art, the utility model electric connector, firm being retained in the insulating body of its tin ball energy, and can not cause loose contact, can realize the better electric connection of electronic component and circuit board.
Description
[technical field]
The utility model relates to a kind of electric connector, and especially a kind of being used for compressed the electric connector that contacts mutually with chip module.
[background technology]
Occurred a kind of chip module of LGA type now on some electronic product (as computer), the guiding access of this chip module is a washer-shaped, and the electric connector that is attached thereto is provided with the terminal that contacts with the conducting end compression.The electric connector of prior art, comprise insulating body and conducting terminal, insulating body is provided with the terminal containing slot of accommodating conducting terminal, conducting terminal is to be made of one piece, comprise and be immobilizated in intrinsic holding parts, holding parts extension downwards is provided with the weld part that welds mutually with circuit board, extend upward and be provided with the contact site that compresses contact with chip module mutually, this electric connector is provided with a tin ball to weld mutually with circuit board below weld part, general tin ball is by in the tin ball accommodation hole that is clamped in the setting of insulating body below, but the tin ball fixing of this structure is insecure, and tin ball and weld part loose contact, can influence the normal electric connection of electric connector.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[utility model content]
The purpose of this utility model is to provide a kind of novel electric connector, can realize the better electric connection of electronic component and circuit board.
For achieving the above object, the utility model electric connector comprises the insulating body, plurality of conductive terminals and the corresponding scolder that is attached at conducting terminal that are provided with the terminal accommodation hole, and the zone that terminal and scolder attach is provided with scaling powder.
Compared with prior art, the utility model electric connector, firm being retained in the insulating body of its tin ball energy, and can not cause loose contact, can realize the better electric connection of electronic component and circuit board.

[embodiment]
See also illustrated in figures 1 and 2ly, the utility model electric connector comprises insulating body 1, plurality of conductive terminals 2 and the corresponding scolder (being tin ball 3 in the present embodiment) that is attached at conducting terminal 2.
Wherein, insulating body 1 is provided with dented space 10, can hold chip module (certainly, also can be other butt joint electronic component), be provided with plurality of terminals accommodation hole 11 in the dented space, conducting terminal 2 is contained in this terminal accommodation hole 11, the terminal accommodation hole below of insulating body 1 also is provided with scolder accommodation hole 12, scolder accommodation hole 12 part sizes are less than tin ball 3, fix the tin ball is pressed into produce, these tin ball 3 parts protrude from insulating body 1 lower surface, to weld mutually with circuit board (not icon), the zone that described terminal and tin ball are attached is provided with scaling powder 4, can make the tin ball tightr with contacting of terminal.In addition, in described terminal 2 and the zone that tin ball 3 attaches nickel plating (not shown) is arranged, it can promote resistance to corrosion, so that welding, and described terminal 2 and the zone gold-plated in addition (not shown) that tin ball 3 attaches, can improve the conduction contact impedance, promote the signal transmission.
Conducting terminal 2 is to be made of one piece, comprise the holding parts 20 that is immobilizated in the insulating body, holding parts extension downwards is provided with the weld part 21 that welds mutually with circuit board, extend upward and be provided with the contact site 22 that compresses contact with chip module (not icon) mutually, described tin ball 3 is fixed by terminal 2 tail end weld part clampings.
The utility model electric connector loose contact can not occur because the setting of scaling powder makes the tin ball tightr with contacting of terminal, can realize the better electric connection of chip module and circuit board.
Please refer to second embodiment that Figure 3 shows that the utility model electric connector, itself and the foregoing description difference are: weld part 21 is formed by holding parts 20 bending extensions, and tin ball 3 grips by scolder accepting hole 12, also can reach same effect.
Please refer to the 3rd embodiment that Figure 4 shows that the utility model electric connector, itself and the first embodiment difference are: terminal tails weld part 21 is positioned at a side of scolder accommodation hole 12, this terminal tails and accommodation hole opposite side grip tin ball 3 jointly, also can reach same effect.
Please refer to Fig. 5 and Figure 6 shows that the 4th embodiment of the utility model electric connector, itself and the first embodiment difference are: terminal tails weld part 21 is provided with a hook part 23, and this hook part 23 can be colluded tin ball 3 and be held fixingly, also can reach same effect.
