[background technology]

Since CNT (carbon nano-tube) be Japanese physicist's Sumio Iijima after 1991 observe and report, every field produces unprecedented interest to CNT (carbon nano-tube), and then drops into more resources and study nanometer technology.Because material shows very outstanding physics and chemical characteristic under nano-scale, therefore the nanosecond science and technology institute that the become every field Holy grail pursuing and develop, every field is there's no one who doesn't or isn't fallen over each other and is dropped into the exploitation and the application of CNT (carbon nano-tube), in the hope of giving existing product innovation life.

United States Patent (USP) bulletin US6,626,684 have disclosed a kind of CNT (carbon nano-tube) that adopts is contained among the connector body electric connector with transmitting signals, this kind electric connector thinner thickness.Right this CNT (carbon nano-tube) contact jaw directly contacts with chip module and circuit board, because of CNT (carbon nano-tube) does not have elasticity and traditional CNT (carbon nano-tube) surface irregularity, causes easily to electrically contact instability.

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: a kind of stable electric connector that electrically contacts is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electric connector, comprise insulating body and some conductive paths, insulating body is provided with upper and lower surface and the some accepting grooves that runs through upper and lower surface that is oppositely arranged, conductive path is contained in the accepting groove, and conductive path comprises first electrode, second electrode that is arranged at upper and lower surface respectively and connects first electrode and the CNT (carbon nano-tube) of second electrode.

Further first electrode and second electrode are in the projection dislocation of lower surface.

Further first electrode is identical with the shape of second electrode.

Further first, second electrode all is that resilient metal member and each electrode are provided with the outer contact-making surface of at least one outstanding insulating body.

Further insulating body comprises the side perpendicular to upper surface, and first, second electrode is provided with to the connecting portion of insulating body side extension in order to the splicing ear strip.

Further first, second electrode is respectively equipped with to insulating body upper surface and lower surface and extends connecting portion in order to the splicing ear strip.

Further first, second electrode is arranged along the diagonal on the upper and lower surface of insulating body respectively.

Further first electrode and the second electrode plug-in type are overmolded in the insulating body.

Compared with prior art, first electrode of the utility model electric connector is connected with external module as electrically contacting end with second electrode, can avoid CNT (carbon nano-tube) to electrically contact problem of unstable as contact jaw.

[embodiment]

Fig. 1 to Fig. 4 is first preferred embodiment of the present utility model, this embodiment electric connector 100 comprise be provided be oppositely arranged upper and

lower surperficial

11,12 and somely run through the insulating body 1 of upper and

lower surperficial

11,12 accepting groove 13 and be contained in conductive path 2 in the accepting groove 13.

Conductive path 2 comprises first electrode 21, second electrode 22 that is arranged at upper and lower surperficial 11,12 respectively and the CNT (carbon nano-tube) 23 that connects first electrode 21 and second electrode 22.First electrode 21 and second electrode, 22 plug-in types are overmolded in the insulating body 1, and its shape is identical and all are resilient metal member.Each

electrode

21,22 is wavy and is provided with at least one outstanding insulating body 1 contact-making surface 210,220 outward.Wherein the contact-making surface 210 of first electrode 21 projects upwards upper surface 11, in order to electrically contact chip module (not shown); The contact-making surface 220 of second electrode 22 is outstanding lower surface 12 downwards, in order to electrically contact circuit board (not shown).Because of first,

second electrode

21,22 has elasticity, it can contact better with chip module (not shown) and circuit board (not shown).Insulating body 1 also comprises the side 14 perpendicular to upper surface 11, and first,

second electrode

21,22 is provided with the connecting portion 211,221 that extends in order to splicing ear strip 3 to the side 14 of insulating body 1, joins shown in Figure 4.

The forming method of electric connector 100 is as follows: at first be ready to connecting first electrode 21 and second electrode 22 of terminal material belt 3, in the Overmolded mode of plug-in type with first,

second electrode

21,22 and insulating body 1 ejection formation simultaneously; In the accepting groove 13 of insulating body 1, inject the dispersion liquid that contains the CNT (carbon nano-tube) powder then; Between the terminal material belt 3 that first,

second electrode

21,22 connects, apply a predetermined voltage afterwards, make CNT (carbon nano-tube) powder swimming in the dispersion liquid, and then formation CNT (carbon nano-tube) 23 between first electrode 21 in accepting groove 13 and second electrode 22, CNT (carbon nano-tube) 23 two ends are attached to first,

second electrode
