Abstract
The utility model discloses an electric connector, comprising an isolation body and a conductive terminal. The conductive terminal comprises a current terminal and a signal terminal, and the cross-section of the current terminal is greater than that of the signal terminal. The isolation body is provided with a first accommodating groove and a second accommodating groove for accommodating the current terminal and the signal terminal. Compare with prior art, the electric connector can bear higher electric current when ambient electric voltage does not change, so as to meet the electric property requirement of a CPU chip.
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]
Now, the chip module that a kind of LGA type on some electronic product such as computer, occurred, the guiding access of this chip module is a washer-shaped, being attached thereto the electric connector that connects is provided with and the guiding access of the chip module terminal of elastic compression contact mutually, undertaking the effect of transmitting signal and electric current, and in the same electric connector in order to compress shape, size, the material of the terminal that contacts mutually all identical with chip module.Yet along with further developing of electronic information technology, require in the same electric connector to carry the terminal of electric current can bear bigger electric current, under the constant situation of input voltage, the resistance that hides the terminal that just requires to carry electric current reduces.Existing electric connector usually adopts the gold-plated resistance that reduces terminal itself on some terminal so that under the constant situation of external voltage, terminal can bear higher electric current.Yet the defective of the prior art is: along with cpu chip requires to bear electric current when more and more higher to the terminal of carrying electric current, because the size of resistance and the structure of terminal self have very big relation, therefore depending merely at the gold-plated resistance that reduces of terminal appearance is not satisfy needs, promptly depend merely on gold-plated, terminal can not bear high electric current, does not satisfy the electric property requirement of cpu chip.
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 with a kind of electric connector is provided, to satisfy the electric property requirement of cpu chip.
For achieving the above object, the utility model electric connector comprises insulating body and conducting terminal, and wherein conducting terminal comprises some current terminals and signal terminal, and the sectional area of current terminal is greater than the sectional area of signal terminal.
Compared with prior art, the utility model electric connector is by using the conducting terminal of varying cross-section area, so that different classes of conducting terminal has different resistance, because of the resistance of conducting terminal itself and the cross-sectional area of conducting terminal have inversely prroportional relationship, when increasing the sectional area of conducting terminal, its resistance just reduces a lot, thereby under the constant situation of external voltage, can bear higher electric current, satisfy the electric property requirement of cpu chip.

The cutaway view that Fig. 5 is fitted together for the utility model electric connector and chip module and circuit board group.
[embodiment]
With reference to the accompanying drawings the utility model electric connector is made and further specifying.
Referring to figs. 1 through Fig. 5, the utility model electric connector electrically connects planar lattice array chip module 40 to printed circuit board (PCB) 50 in the plane mode of pushing, and it comprises insulating body 10 and the tin ball 30 that is contained in the conducting terminal in the insulating body 10 and is welded in the conducting terminal bottom.
With reference to Fig. 1, insulating body 10 is rectangular-shaped, which is provided with a series of accepting groove, be divided into first accepting groove 11 and second accepting groove 12, wherein first accepting groove 11 is identical with the degree of depth of second accepting groove 12, the surface area difference, and the surface area of first accepting groove 11 is about 2 times of surface area of second accepting groove 12, and insulating body 10 upper ends are provided with projection 13, with positioning chip module 40 (as shown in Figure 5).
With reference to Fig. 2, Fig. 3 and Fig. 4, conducting terminal is roughly " U " shape, be contained in the insulating body 10, comprise current terminal 21 that is contained in first accepting groove 11 and the signal terminal 22 that is contained in second accepting groove 12, and the sectional area of current terminal 21 is greater than the sectional area of signal terminal 22, wherein current terminal 21 and signal terminal 22 are equipped with the last contact site 211 and 221 that compresses contact with the chip module (not shown) mutually, the following contact site 212 and 222 that is connected with circuit board; Tin ball 30 is welded in the following contact site 212 and 222 of current terminal 21 and signal terminal 22.
Fig. 5 connects planar lattice array chip module 40 to printed circuit board (PCB) 50 cutaway views for the utility model electric connector.On electric connector assembling and the circuit board, the reference column 14 on the insulating body 10 inserts in the corresponding aperture 51 of circuit boards 50, further is provided with Elastic buckle 15 on the insulating body, is used for predetermined fixed chip module 40.
Certainly, the free terminal of the reference column 14 on the insulating body 10 can also further be provided with the hook (not shown), so that insulating body is fixed on the circuit board, wherein hook can be come out with reference column is integrally manufactured, also can make (being preferably metal material makes) separately.
When electric connector is connected with the circuit board (not shown), can utilize solder technology, tin ball 30 is welded on the circuit board, realize being connected of electric connector and circuit board.
Certainly, the utility model electric connector can not wanted the tin ball yet, and the following contact site by conducting terminal directly is welded on the circuit board, perhaps descends contact site to compress mutually with circuit board and contacts, and realizes the electric connection of electric connector and circuit board.
By the utility model technological means, promptly, reduce the resistance of conducting terminal, thereby under the constant situation of voltage, conducting terminal can bear higher electric current, satisfies the electric property requirement of cpu chip by increasing the cross section of some conducting terminal.
