Therefore, the necessary defective that provides a kind of improved electric connector to exist with the electric connector that solves the above-mentioned type.

[summary of the invention]

The technical problem to be solved in the present invention provides a kind of lower-cost electric connector of insulating body.

For solving the problems of the technologies described above, the invention provides a kind of electric connector, can electrically connect chip module to circuit board, it comprises insulating body, wherein said insulating body comprises base portion, the upper surface of base portion is provided with some discontinuous keepers, described some keepers surround a receiving space to accommodate chip module, the part of the corresponding receiving space of base portion has been installed with plurality of conductive terminals, wherein base portion is provided with first, the second side, and difference the on the other side the 3rd, four side, described keeper comprise somely is located at first, projection on the second side, and somely be located at the 3rd, elastic arm on the four side.

Compare with correlation technique, the insulating body of electric connector of the present invention comprises base portion, and base portion is provided with a receiving space that is surrounded by some discontinuous keepers, and accommodating chip module, so materials are less, and then reduced production cost.

[embodiment]

See also Fig. 1 to shown in Figure 4, electric connector of the present invention (not label) can electrically connect chip module (not shown) to circuit board (not shown), and it comprises insulating body 2, some conducting terminals 3 that is contained in the insulating body 2.

Insulating body 2 is provided with a flat base portion 20, and the some discontinuous keeper of being located at base portion 20 upper surfaces 200, some keepers surround a receiving space (not label), to accommodate chip module, offer plurality of terminals accepting groove (not label) on the part of base portion 20 corresponding to receiving space, described conducting terminal 3 correspondences are contained among the above-mentioned terminal containing slot.

Base portion 20 is provided with first, second side 201,202, and relative with first, second side 201,202 respectively the 3rd, four side 203,204.Described keeper can be one-body molded with base portion 20, it also can be independent element, comprise the some projections (not label) on first, second side 201,202, and somely be located at the 3rd, the elastic arm 206 on the four side 203,204, wherein said projection all extends upward from the upper surface 200 of base portion 20, and its inboard towards receiving space is smooth setting to make things convenient for chip module embedding receiving space.The lower surface of base portion 20 (not label) convex with some reference columns (not label) with circuit board on the location hole (not shown) of corresponding setting cooperate.

Elastic arm 206 comprises the arm of force 2062 that extends along almost parallel base portion 20 directions from the upwardly extending connecting portion 2060 of base portion 20 upper surfaces, from connecting portion 2060, the end of the described arm of force 2062 convexes with projection 2064 towards receiving space, the part of the arm of force 2062 of corresponding elastic arm 206 offers opening 208 on the base portion 20, the shape of described opening 208, size and the shape of the arm of force 2062, big or small corresponding, thus, make the arm of force 2062 be hanging shape.The bottom of the above-mentioned arm of force 2062 can be set as the upper surface 200 a little more than base portion 20, can guarantee so can not interfere with base portion 20 when strain takes place the arm of force 2062; Also can be set as the upper surface that is lower than base portion 20, at this moment, the space of above-mentioned opening 208 should be provided with enough big, prevents that the arm of force 2062 from interfering with the inwall of opening 208 behind the compressive deformation when chip module embeds receiving space.

When chip module is assembled to electric connector, chip module is embedded in the receiving space that above-mentioned keeper surrounds, because the arm of force 2062 of elastic arm 206 is hanging shape, therefore, when chip module embeds, behind the arm of force 2062 pressurizeds enough strains can take place, make chip module be able to smooth embedding.After chip module embedded receiving space, the arm of force 2062 of elastic arm 206 pushed chip module under the effect of elastic restoring force, and described protruding 2064 are pressed on the chip module.Base portion 20 the 3rd, be equipped with plurality of elastic arm 206 on the four side 203,204, respectively with the 3rd, then be provided with some projections on corresponding first, second side 201,202 of four side 203,204, thus, the projection of plurality of elastic arm 206 and 206 settings of corresponding elastic arm is positioned at chip module in the receiving space together.The part of corresponding receiving space contains plurality of conductive terminals 3 on the base portion 20, and the conducting position of corresponding setting electrically contacts on an end of these terminals and the chip module, and the other end then electrically contacts with circuit board, thereby chip module is electrically connected to circuit board.

Obviously, discontinuous keeper on base portion 20 each sides of electric connector insulating body 2 of the present invention is not limited to concrete structure, shape and the distributing position described in the above-mentioned embodiment, in fact, they can be arranged to arbitrarily shape and be arranged in position arbitrarily, if can surround a receiving space with accommodate and the positioning chip module in wherein.
