[embodiment]
See also Fig. 1 to Fig. 6, electric connector 1 of the present invention, in order to electrically connect chip module (not shown) and circuit board (not shown), it comprises matrix 10, be contained in plurality of conductive terminals 20 in the matrix, be connected to the lid 30 on the matrix 10 and be mounted on matrix 10 and lid 30 between elastic component, in the present embodiment, this elastic component is a spring 40.
Conducting terminal 20 is contained in the matrix 10 corresponding terminal containing slots 103 by matrix-style, the elastic arm 202 that each conducting terminal 20 comprises holding parts 201, extend obliquely from holding parts 201 upper ends and connect afterbody 203 from what the bending of holding parts 201 lower ends was extended, end in elastic arm 202 is provided with contact site 2021, this contact site 2021 stretches out the upper surface 100 outer certain altitudes of matrix 10, to be electrically conducted in chip module; Be contained in the elastic arm 202 of the conducting terminal in delegation's terminal containing slot 103 20 parallel to each otherly, and the projection of elastic arm 202 on the plane that is parallel to matrix 10 upper surfaces 100 of any two adjacent conducting terminals 20 overlapped each other.
Lid 30 floats and is connected on the matrix 10, and this lid 30 be the rectangular plate shape structure similar to matrix 10, but its be provided with the carries chips module continuing surface 300 and and the interface 301 that is connected with group of matrix 10; Lid 30 is respectively equipped with the grab 302 that extends to matrix 10 directions in the opposite end of its interface 301, and these grabs 302 have certain elasticity, and its location hole 105 with matrix 10 two ends is corresponding and can cooperatively interact; Lid 30 outwards is provided with projection 303 in the middle part of one lengthwise side corresponding to the raised position place in the middle part of matrix 10 respective side edge, this projection 303 can cooperate in the holding hole 106 that is contained on matrix 10 projectioies, lid 30 is respectively equipped with a pair of accepting hole 304 in its opposite end corresponding to blind hole 104 positions at matrix 10 two ends, these accepting holes 304 extend to certain depth and do not connect to continuing surface 300 directions from lid 30 interfaces 301, to accommodate the other end of spring 40.
During assembling; earlier conducting terminal 20 is inserted in the terminal containing slot 103 of matrix 10; again spring 40 is inserted in the matrix 10 corresponding blind holes 104; and an end that makes spring 40 is resisted against the bottom surface of blind hole 104; then lid 30 and matrix 10 are connected with group; even match in the positioning hole corresponding 105 of the grab of lid 30 302 insertion matrixes 10 and with it; the other end of spring 40 inserts in the corresponding accepting hole 304 of lid 30; this moment, lid 30 was in primary importance by means of the supporting role of spring 40; each interval certain distance between the interface 301 of lid 30 and the upper surface 100 of matrix 10; the contact site 2021 of conducting terminal 20 protrudes in the upper surface 100 of matrix 10 and is contained in the perforate 305 of lid 30; and be not exposed to the continuing surface 300 of lid 30; because perforate 305 is provided with the corresponding extension of each row conducting terminal respectively; event all can be contained in the same corresponding perforate 305 with the contact site 2021 of the conducting terminal 20 that delegation's being hit by a bullet property arm 202 overlaps each other; like this; conducting terminal 20 promptly can be effectively protected in transportation; avoided damaging, thereby guaranteed to electrically connect reliably between electric connector and chip module because of improper external force effect makes its contact site 2021.
During use, chip module is placed on the continuing surface 300 of lid 30, apply external force effect to chip module this moment, under this external force effect, spring 40 is out of shape pressurized generation elastic shrinkage, owing to exist between lid 30 and the matrix 10 at interval, lid 30 generals move to the direction of matrix 10 under pressure, and the contact site 2021 of conducting terminal 20 also will relatively move to its continuing surface 300 directions along the perforate 305 of lid 30, continue to force on the chip module, spring 40 further contraction distortions contact with the upper surface 100 of matrix 10 until the composition surface 301 of lid 30, this moment, lid 30 was in the second place, projection 303 on the lid 30 is contained in the holding hole 106 on the matrix, the contact site 2021 of conducting terminal 20 passes the perforate 305 of lid 30 and protrudes in outside its continuing surface 300, and contact with the conductive spacer (not shown) of chip module to form and electrically conduct, thereby part is electrically connected to circuit board with chip module.
