Abstract
The utility model discloses an electric connector which comprises an insulating body and conductive bodies, wherein the insulating body is provided with a plurality of containing holes, each containing hole comprises two opposite openings and a containing part for connecting the two openings, the area of the cross section of the containing part is smaller than that of each opening, and each conductive body is positioned outside one opening of the each containing hole and comprises conductive particles and elastic colloid for positioning the conductive particles. The electric connector has strong conductivity and low cost.
Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of compression contact-type electric connector especially.
[background technology]
Compression contact-type electric connector of the prior art generally comprises the insulating body with some accepting holes and is arranged at conductive component in the accepting hole, and conductive component comprises some conductive particles and is arranged at the outer elastomer of conductive particle.Conductive component is by compressing the electric connection that contact realizes two butt joint electronic building bricks mutually with two butt joint electronic building bricks.As the electric connector that the United States Patent (USP) bulletin discloses for US5624268 number, its conductive component is arranged in the accepting hole and partly protrudes from the upper and lower surface of insulating body, and the accepting hole of this electric connector is the cylinder of rule.The conductive particle of this kind conductive component needs higher concentration, and electrically contact is good can to guarantee two butt joint electronic building bricks, and the cost of electric connector increases along with the raising of conductive particle concentration.
So, be necessary to design a kind of electric connector, to overcome above-mentioned defective of the prior art.
[utility model content]
The technical problems to be solved in the utility model is: the electric connector cheaply that provides a kind of low concentration conductive particle well to electrically connect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electric connector, it comprises insulating body and electric conductor, insulating body is provided with some accepting holes, accepting hole comprises two relative openings and connects the incorporating section of two openings that electric conductor comprises the elastic gel of conductive particle and location conductive particle, wherein, the cross-sectional area of incorporating section is little than the cross-sectional area of opening, and electric conductor is positioned at outside the opening of accepting hole.
Compared with prior art, the cross-sectional area of the incorporating section of the accepting hole of the utility model electric connector is little than the cross-sectional area of opening, and electric conductor is positioned at outside the opening of accepting hole, enter in the accepting hole behind the electric conductor pressurized, thinner because of the incorporating section, can push conductive particle, make conductive particle comparatively dense in the incorporating section, thereby the electric conductor that guarantees the low concentration conductive particle also can well electrically connect the butt joint electronic building brick, reduces cost thereby reduce conductive particle.

[embodiment]
See also Fig. 1 to Fig. 3, the utility model electric connector 100 (is chip module 400 and circuit board 500 in order to connect two butt joint electronic building bricks in the present embodiment, certainly also can be other butt joint electronic building brick), this electric connector 100 comprises insulating body 2 and electric conductor 3.Insulating body 2 is provided with some accepting holes 21 that run through insulating body 2 upper and lower surfaces, and accepting hole 21 comprises relative first opening 211, second opening 213 and connects the incorporating section 212 of two openings 211,213.
Please in conjunction with consulting Fig. 4 to Fig. 6, first opening 211 is provided with inside chamfering, and incorporating section 212 is positioned at insulating body 2 and is cylindric, and the cross-sectional area of incorporating section 212 is little than the cross-sectional area of first opening 211 and second opening 213.Insulating body 2 is provided with some projections 22 and forms groove 23 in the periphery of first opening 211 of accepting electric conductor 3 of accepting hole 21, and projection 22 is arranged, and is circular-arc near a side of first opening 211, and projection 22 is around electric conductor 3 peripheries.
When chip module 400 and circuit board 500 connect, projection 22 supporting chip modules 400, electric conductor 3 pressurizeds, and by in first opening, the 211 inflow accepting holes 21, elastic gel 32 is more liquid, it flows to accepting hole 21 two ends, and the elastic gel 32 that overflows is incorporated in the groove 23 and second opening 213.The degree of depth of second opening 213 is less than the diameter (consulting Fig. 6 especially) of conductive particle 31, can prevent that conductive particle 213 from dispersing to second opening, 213 peripheries.Conductive particle 31 also is squeezed and draws close to accepting hole 21 middle parts, because of incorporating section 212 thinner, so conductive particle 31 comparatively denses in the incorporating section 212, the electric conductor 2 that can guarantee low concentration conductive particle 212 also can be realized the excellent electrical property conducting, so cost is also along with the quantity of conductive particle reduces and reduces.
In sum, it below only is preferred embodiment of the present utility model, should not limit scope of the present utility model with this, be that every simple equivalent of being done according to the utility model claims and utility model description changes and modifies, all should still belong in the scope that the utility model patent contains.
