[embodiment]

Below in conjunction with accompanying drawing this use novel electric connector is described further.

See also Fig. 1 to Fig. 3, the utility model electric connector 1 comprises insulating body 10 and electric conductor 11 in order to chip module 2 is connected on the circuit board 3.

Insulating body 10 is provided with some accepting holes 101 that run through insulating body 10 upper and lower surfaces, electric conductor 11 is contained in wherein, but accepting hole 101 inwalls are provided with the detent mechanism of locating electric conductor 11, this detent mechanism is to be separately positioned on the protuberance 102 that accepting hole 101 inwall both sides and in the vertical direction stagger mutually in the present embodiment, 103, can in accepting hole 101, swing during electric conductor 11 pressurizeds, accepting hole 101 inwalls up and down correspondence position are arranged with to form on the direction of electric conductor 11 swings and allow bit space 104, and this allows on the inwall of bit space 104 respectively at the inwall of a protuberance 102 tops of staggering mutually on the vertical direction and another protuberance 103 belows.Be provided with the protruding wall 105 in location around the insulating body 10, locate protruding wall 105 and be provided with the elastomer 106 that can collude the core of the card sheet module 2 upper surfaces, be provided with at least two reference columns 107 by the extension downwards of insulating body 10 bottoms, and this two reference column 107 differs in size, when electric connector being installed on the circuit board 3, can play foolproof function, can increase work efficiency.

Electric conductor 11 both sides are concaved with the auxiliary section 12 that can match with detent mechanism, and electric conductor 11 comprises elastomer 110 and is arranged on elastomer 110 multiple layer metal layer outward.This elastomer 110 is an electron opaque material, wherein the multiple layer metal layer is respectively with physical coating mode (as physical coating modes such as vacuum evaporation or vacuum sputterings) or other plated film mode and is plated in elastomer 110 the first metal layer 111 outward, this the first metal layer 111 is a metallic copper, reach with plating mode and be plated in the first metal layer 111 second metal level 112 outward, this second metal level 112 is with thickening the first metal layer 111, so it also is a metallic copper, and second metal level 112 is thick than the first metal layer 111, outside second metal level 112, be coated with one deck nickel dam 113, outside nickel dam 113, be coated with outer layer metal 114, outer layer metal 114 is a gold, nickel dam 113 can improve the resistance to wear and the corrosion resistance of electric conductor 11, and outer layer metal 114 reduces impedance simultaneously for the conductance that gold can improve electric conductor.In order to keep electric conductor 11 to have elasticity preferably, each metal level can be plated on elastomer 110 part surface outward and (be the annular around its part outer surface as the metal level outside elastomer, if implement in this mode, the cutaway view Amplified image of this electric conductor as shown in Figure 3, it is along the cutaway view of analysing and observe the perpendicular direction of direction with Fig. 3 then as shown in Figure 4), and form continuous conductive path (metal level also can be other shape certainly, as long as can be formed into continuous conductive path).Simultaneously, for being plated in outside the elastomer preferably, first conductive layer can before first conductive layer is plated, apply one deck medium (not shown) in outer elastomeric surface earlier, to increase the adhesive force of first conductive layer.(because of this multiple layer metal layer is all thinner except that second metal level, in order obviously to pick out its lines and profile hatching not in cutaway view)

After electric conductor 11 being attached in the accepting hole 101 of insulating body 10, the location of matching with two protuberances 102,103, auxiliary section 12, what at this moment electric conductor tilted is housed in the accepting hole 101, and two ends are protruded insulating body 10 upper and lower surfaces and are formed contact point 116, the line of two contact points 116 and insulating body 10 upper surfaces form an acute angle, and promptly contact point 116 is not on same vertical straight line.When electric connector 1 is connected with chip module 2 and circuit board 3, corresponding contact point 116 and the conducting strip 20 on the chip module 2 and the conducting strip 30 on the circuit board 3 connect, electric conductor 11 pressurizeds are to allowing the swing of bit space 104 directions, because protuberance 102,103 in the vertical directions do not stagger mutually at sustained height, and electric conductor 11 is inclined to be fixed on two protuberances 102 more reliably, between 103, simultaneously, two contact points 116 on one electric conductor are not on same vertical straight line, and allow bit space 104 be arranged so that electric conductor 11 pressurizeds the time can be in the certain space internal strain, can avoid contact point 116 because of the stressed metal level be full of cracks that makes greatly on the conduction topic 11.

The electric conductor of the utility model electric connector is provided with elastomer and multilayer is arranged on its outer conductive layer, both can guarantee that electric conductor had elasticity preferably, its outer metal level also can be realized electrically conducting of chip module and circuit board, can guarantee effectively to be connected between chip module and circuit board, avoid the existing problem of conducting terminal of using metal stamping to form as stated in the Background Art.

Please refer to Fig. 5 implements electric conductor for the utility model electric connector second schematic diagram, the electric conductor 11 ' of present embodiment is with the electric conductor difference of the foregoing description, elastomer 110 ' the outer the first metal layer 111 ' of electric conductor 11 ' is to be wrapped in the thin copper sheet 111 ' of its outer one deck in the present embodiment, copper sheet 111 ' outer surface is coated with one deck nickel 113 ', be coated with outer layer metal 114 ' outside nickel dam 113 ', outer layer metal 114 is a gold.It also can reach the described purpose of the foregoing description in implementation process.
