Abstract

The utility model of an electric connector terminal contained in an insulator is characterized in that the terminal is consisted of an elastic object and a conductive object. Compared with the current technology, the utility model has the advantages that the utility model of the electric connector terminal is a joint of the elastic object and the conductive object, which effectively prevents the conductive object from elastic fatigue and elastic deformation, and is helpful to the effective contact with the externally connected electronic elements.

Description

Electric connector terminal

[technical field]

The utility model relates to a kind of electric connector terminal.

[background technology]

Development along with computer industry, CPU (Central Processing Unit, CPU), the structure of assemblies such as chip template and electric connector itself becomes increasingly complex, its function also from strength to strength, so it is also more and more higher to interconnective accuracy of each assembly and reliability requirement.Be the needs of coupling central processing unit, chip template and circuit board performance, the electric connector terminal that docks with it mostly is highdensity array telecommunication terminal.Be the typical case of pad grid array type terminal structure as depicted in figs. 1 and 2, this terminal is provided with the contact site 10 that contacts with central processing unit or chip template etc., be provided with the weld part 30 that welds with tin ball 40 in the end of this terminal, this terminal sidepiece also is provided with can be against the stop section 30 of contact site 10, the overall structure more complicated, and because contact site is set in the pressure of central processing unit or chip template for a long time, be easy to make termination contact portion 10 that elastic fatigue takes place, influence conducting terminal and contact with the effective of chip template.

Therefore, be necessary to design a kind of novel electric connector terminal, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector terminal that can effectively prevent electric conductor generation elastic fatigue or strain.

To achieve these goals, a kind of electric connector terminal is placed in the insulating body, it is characterized in that: described terminal is by elastomer and electric conductor be combined into.

Compared with prior art, the utlity model has following advantage: the utility model electric connector terminal is owing to be to be engaged by elastomer and electric conductor to form, elastomer can effectively prevent electric conductor generation elastic fatigue or strain, helps contacting with the effective of external connected electronic element.

[embodiment]

Below in conjunction with accompanying drawing the utility model electric connector terminal is described further.

See also Fig. 3 and shown in Figure 4, this real novel electric connector terminal 10 is placed in the electric connector insulating body 50 of (figure does not show), this terminal 10 is semicircular arc and by electric conductor 11 and elastomer 12 be combined intos, and electric conductor 11 is located at terminal 10 skins, and elastomer 12 is located at terminal 10 internal layers, this electric conductor 11 has high conductivity material to make (as red metal), and elastomer 12 is made by the metal material of good springiness, and electric conductor 11 is bonded together by chemical substance 13 with elastomer 12.On described electric conductor 11, be provided with and dock the contact site 111 that electronic component 60,70 contacts.During assembling,, can effectively prevent owing to contacting the strain that takes place with 50,60 compressions of butt joint electronic component because elastomer 12 is positioned at the internal layer of terminal 10.

Shown in Figure 5 is the schematic diagram of second embodiment of the utility model electric connector terminal 20, different with the foregoing description is: electric conductor 21 with elastomer 22 by being crimped on, other structure of this embodiment and function are all same as the previously described embodiments, below repeated description not just.

Fig. 6 and Fig. 7 are the schematic diagrames of the 3rd embodiment of the utility model electric connector terminal 30, different with first embodiment is: electric conductor 31 snaps together with elastomer 32, and electric conductor 31 all roughly is the opposite arc of direction with elastomer 32, two recesses 311 have been bent to form at the both ends of electric conductor 31, and being provided with two projections 321 in elastomer 32 corresponding positions, this projection 321 is buckled in corresponding 11 so that electric conductor 31 snaps together with elastomer 32.

Fig. 8 to Figure 10 is the schematic diagram of the 4th embodiment of the utility model electric connector terminal 40, though electric conductor 41 also is fastened togather with elastomer 42, but different with above-mentioned the 3rd embodiment is: be provided with two trips 411 at the both ends of electric conductor 41, and be provided with two through holes 421 in elastomer 42 corresponding positions, described trip 411 is fastened in the corresponding through hole 421, so that electric conductor 41 and elastomer 42 are fastened togather.

Four embodiment of the utility model electric connector terminal, though have nothing in common with each other, but terminal all is to be formed by electric conductor and elastomer-bonded, and electric conductor can both well prevent elastomer generation elastic fatigue or strain, helps contacting with butt joint the effective of electronic component.
