[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electronic component is described further.

Extremely shown in Figure 6 as Fig. 1, electronic component is electric connector 1 (also can be other electron components such as circuit board certainly) in the present embodiment, be used for connecting butt joint electronic component 2 (being chip module in the present embodiment) and circuit board 3, it comprises that insulating body 11 and at least one are contained in the electric conductor in the insulating body 11, this electric conductor includes low-impedance liquid metal 12 and (is mercury in the present embodiment, certainly also can be other low-impedance liquid metal), liquid metal 12 two ends are connected with metallic object 13.

This insulating body 11 comprises interfix two-layer up and down 14,15, and two-layer up and down insulating body forms accommodation hole 16 jointly.These accommodation hole 16 volumes are a bit larger tham liquid metal 12 volumes, can flow toward the gap when making liquid metal 12 pressurizeds; Accommodation hole 16 two ends have smaller opening 17, and two openings 17 are equipped with outside chamfering 18, two opening parts up and down at accommodation hole 16 respectively are provided with a movable and curved metallic object 13, its two end portions is arranged in accommodation hole 16, mid portion then protrudes in the surface of insulating body 11, can contact with circuit board 3 and chip module 2 respectively (welding manner or the compression way of contact), thereby make circuit board 3 plates and chip module 2 reach electric connection (as shown in Figure 6).In addition, these insulating body 11 upper and lower surfaces are equipped with location structure, and this location structure is respectively positioning frame body 19 and reference column 20 in upper and lower surface, but these positioning frame body 19 frames are lived chip module 2 peripheries to be located, and this reference column 20 can insert in the corresponding perforations on the circuit board 3 (not drawing among the figure) and be located.

Certainly the utility model electronic component also can be used for connecting two circuit boards, and this moment, insulating body 11 upper and lower surfaces were equipped with reference column, inserts respectively in the hole of corresponding circuits plate (as Fig. 7, shown in Figure 8).

With reference to Fig. 9, be the 3rd embodiment of the utility model electronic component.In the present embodiment, insulating body 11 is as a whole, which is provided with accommodation hole 16, the upper shed of accommodation hole 16 is less, and under shed is bigger, opening part is provided with mobilizable first metallic object 13 ' thereon, and first metallic object 13 ' is provided with a projection, can give prominence to insulating body 11 and contact with the butt joint electronic component.Its lower opening is installed with second metallic object, 13, the second metallic objects 13 and does not stretch out insulating body 11, can weld together mutually with the butt joint electronic component.Liquid metal 12 is positioned at the spatial accommodation that accommodation hole 16 and first metallic object 13 ', second metallic object 13 form, and spatial accommodation is greater than the volume of liquid metal 12.
