Electric connector

[technical field]

The utility model relates to a kind of connector, refers in particular to a kind of electric connector that prevents terminal elastic contact arm generation permanent deformation.

[background technology]

A kind of LGA (Land Grid Array has appearred on some electronic product (as computer) now, plane coral lattice array) chip module of type, 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. 1, shown in Figure 2, 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 positive force of this terminal elastic arm end is less, and that the chip template is pressed on the power of contact of conducting terminal is bigger, so just be easy to make the elastic arm generation permanent deformation of conducting terminal, thereby radiography rings the normal use 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 electric connector that prevents terminal elastic contact arm generation permanent deformation.

The purpose of this utility model is, the utility model electric connector comprises, insulating body and be contained in conducting terminal in the insulating body, the elastic contact arm that this conducting terminal is provided with body and can contacts with external electronic building brick elastic compression, the elastic contact arm back side is provided with the elastic gel that can prevent terminal elastic contact arm generation permanent deformation when the conducting terminal pressurized.

Compared with prior art, the utlity model has following advantage: on the elastic contact arm back side of conducting terminal, be provided with elastic gel, can prevent the elastic contact arm generation permanent deformation of conducting terminal like this, guarantee that conducting terminal effectively contacts with external electronic building brick.
