Abstract

The utility model relates to a conductive terminal pack. The terminal pack consists of a first conductive terminal and a second conductive terminal. The utility model is characterized in that: the first conductive terminal is arranged with a first contact part and a pressure offsetting part, and the second conductive terminal with a elastic part that can offset the pressure part. When the first conductive electric terminal is pressurized, a pre-stressing will be produced between the pressure offsetting part and the elastic part. The frontal force of the conductive terminal can be effectively increased, thereby decreasing the contact resistance, and ensuring the effective contact of the contact terminal with the chip set.

Description

A kind of conducting terminal group

[technical field]

The utility model relates to a kind of conducting terminal group.

[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 Fig. 5, shown in Figure 6, 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 conductive terminal, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of novel conducting terminal group, 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 conducting terminal group, comprise first conducting terminal and second conducting terminal, described first conducting terminal is provided with first contact site and pressure section, described second conducting terminal is provided with the elastic portion that can compress described pressure section, when the first conducting terminal pressurized, produce precompression between pressure section and the elastic portion.

Compared with prior art, the utility model conducting terminal group, second conducting terminal is provided with the elastic portion that can compress the first conducting terminal pressure section, when the first conducting terminal pressurized, produce precompression between pressure section and the elastic portion, can effectively increase the positive force of conducting terminal, thereby reduce contact resistance, can guarantee that conducting terminal effectively contacts with chip module.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model conducting terminal group is described further.

See also Fig. 1 to Fig. 4, the utility model conducting terminal group, in order in the accepting hole 30 that is mounted on insulating body 3 to form electric connector, this terminal group comprises first conducting terminal 1 and second conducting terminal 2.

First conducting terminal 1 comprises first main part 10, extend upward by first main part, 10 upper ends and to be provided with first contact site 12, this first contact site 12 can compress contact mutually with external connected electronic assembly (being chip module 4 in the present embodiment), extended to the direction opposite with first contact site 12 by first main part, 10 lower ends and to be provided with pressure section 14, pressure section 14 ends are provided with projection 16.

Second conducting terminal 2 comprises second main part 20, extend upward inflection again by an end of second main part, 20 1 sides and extend to form elastic portion 24, these elastic portion 24 parts up, elasticity is better, extend upward with the other end of elastic portion 24 the same sides on second main part 20 and be provided with fixed part 25, fixed part 25 is provided with the depression 26 that can match with the projection 16 on first conducting terminal 1.Extended by opposite side opposite with being provided with elastic portion 24 on second main part 20 and to be provided with second contact site 22, this second contact site 22 also can compress contact mutually with another external module (being circuit board 5 in the present embodiment).

With first, second conducting terminal 1,2 are assemblied in the accepting hole 30 of insulating body 3, first,

second contact site

12,22 protrude insulating body 3 upper and lower surfaces, pressure section 14 is pressed on the elastic portion 24, pressure section 14 terminal with fixed part 25 corresponding walls between have and can limit the angle 6 that first conducting terminal is excessively swung, when the chip module 4 and the contact site 12 of first conducting terminal 1 compress contact mutually, produce precompression between pressure section 14 and the elastic portion 24, can effectively increase the positive force of first conducting terminal 1, thereby the reduction contact resistance can guarantee that first conducting terminal 1 effectively contacts with chip module 4.
