Abstract

The utility model relates to an electric connector which comprises an insulating body and conductive terminals, wherein the insulating body is provided with a plurality of containing holes in which the conductive terminals are arranged. The conductive terminal is provided with an elastic arm protruding the upper surface of the insulating body and a contact point extended by the elastic arm. The electric connector is also provided with an elastic insulating body. The elastic arm can be bunted on the elastic insulating body when the elastic arm is stressed. Because the elastic arm is supported by the elastic insulating body, the positive force of the contact point of the conductive terminal is increased effectively. Therefore, the utility model can decrease the contact resistance and ensure the effective contact of the conductive terminal and the chip module.

Electric connector

[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 connected on the circuit board is provided with the conducting terminal that contacts with the guiding access compression.This of prior art kind of electric connector, please refer to Figure 10, shown in Figure 11, this electric connector comprises insulating body 50, conducting terminal 60 and is arranged at tin ball 70 under the conducting terminal, this conducting terminal 60 is provided with the elastic arm 601 of outstanding insulating body 50 upper surfaces, elastic arm 601 ends are provided with contact site 602, when assembling with chip module (not shown), chip module is pressed from top to bottom, thereby reach electric connection with the contact site 602 of elastic arm 601 ends, and realize chip module and dock being electrically conducted of circuit board (not shown).But there is following defective in this electric connector: the contact site strength of this terminal elastic portion end is less, causes the positive force of conducting terminal less, thereby causes contact resistance bigger, even may influence conducting terminal and contact with the effective of chip module.

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 novel electric connector, and it can reduce contact resistance, and can guarantee that conducting terminal effectively contacts with chip module.

For achieving the above object, the utility model electric connector, comprise insulating body and conducting terminal, insulating body is provided with some accommodation holes, conducting terminal is contained in wherein, conducting terminal is provided with the elastic arm of outstanding insulating body upper surface and the contact point that is extended to form by elastic arm, and this electric connector is provided with elastic insulator in addition, and elastic arm can be connected on the elastic insulator when stressed.

Compared with prior art, the utility model electric connector is provided with elastic insulator, when elastic arm is stressed, can be connected on the elastic insulator, obtain the support of elastic insulator because of elastic arm, can effectively increase the positive force of conducting terminal contact point, so can reduce contact resistance, and can guarantee that conducting terminal effectively contacts with chip module.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

See also Fig. 1 to Fig. 3, the utility model electric connector comprises insulating body 1 and plurality of conductive terminals 2 in order to connect chip module (not shown) and circuit board (not shown).

Insulating body 1 is provided with plurality of terminals accommodation hole 10, in order to accommodate conducting terminal 2, be provided with elastic insulator at insulating body 10 upper surfaces, this elastic insulator is that plug-in type takes shape on the insulating body 10 and protrudes in the projection (in the present embodiment should projection be the salient point 3 that is arranged at 10 of terminal accommodation holes) of insulating body 10 upper surfaces.

Conducting terminal 2 comprises body 20, be bent to form elastic arm 21 after extending upward by body 20, the upper surface of elastic arm 21 outstanding insulating bodies 20, and depart from certain angle at vertical direction and body 20, the contact point 22 that extends to form by elastic arm 21 ends, above-mentioned salient point 3 on the insulating body and be positioned at the elastic arm 21 of conducting terminal and contact point 22 below, when being subjected to downward power, can support conducting terminal the elastic arm 21 of conducting terminal, be provided with welding ends 23 by body 20 extension downwards, welding ends 23 is provided with scolder 4, in order to weld with circuit board (not shown).

When assembling with chip module (not shown), chip module can force elastic arm 21 to move down, when moving to the precalculated position, salient point 3 can be run into and butt is lived the elastic arm 21 of conducting terminal, need bigger power when elastic arm 21 is further moved down, make to have bigger positive force between conducting terminal 2 and the chip module, thereby reduce contact resistance, and can guarantee that conducting terminal effectively contacts with chip module, and this conducting terminal structure is simpler.

See also Fig. 4 to Fig. 6, implement illustration, be that with the foregoing description difference the elastic insulator that present embodiment is arranged at the insulating body upper surface is not a salient point, but be arranged at the strip bulge 5 between the terminal accommodation hole for second of the utility model electric connector.It also can reach the described purpose of first embodiment in implementation process.
