[embodiment]

See also Fig. 3 to Fig. 5, the utility model electric connector 1 is used to electrically connect wafer module 60 and circuit board (not shown), and it comprises that the insulating body 10, the bag that are equipped with plurality of conductive terminals 12 be located at the reinforced sheet 20 in insulating body 10 outsides, the pressing plate 40 that is articulated in the shifting part 30 of reinforced sheet 20 1 sides and is articulated in reinforced sheet 20 opposite sides.

Insulating body 10 is the tabular structure, be provided with conduction region 14 in its middle part, the plane that this conduction region 14 makes progress is an interface 15, offer plurality of terminals in conduction region 14 and accommodate passage 16, each is accommodated and contains a corresponding conducting terminal 12 in the passage 16, the guiding access of conducting terminal 12 (not label) extend in outside the interface 15 with the conducting strip (not shown) of wafer module 60 bottom surfaces to push the mode butt, insulating body 10 is provided with some locating convex blocks 18 in its bottom surface.Electric connector 1 is electrically connected to circuit board by its conducting terminal 12 and realizes electrically connecting with circuit board, finally realizes being electrically conducted of wafer module 60 and circuit board with being electrically conducted of conducting strip of wafer module 60 by conducting terminal 12 again.

Shifting part 30 is formed by long and thin metal round bar bending several times, it comprises Actuator Division 32 and the holding parts 34 that links to each other with Actuator Division 32 approximate vertical, Actuator Division 32 is provided with the handle 33 of outside bending in its end, and holding parts 34 convexes with the portion 35 that exerts pressure in its middle part.

Pressing plate 40 is a hollow casing structure, its two opposed side edges is respectively first side 41 and second side 42, there is extension 411 at the middle part of first side 41 along the camber line bending extension, second side 42 symmetries extend the holding part 421 that a pair of cross section is the semicircle arcuation, extend the operating portion 422 that roughly is strip between two holding parts 421.Pressing plate 40 is heaved to insulating body 21 directions from the middle part that connects the limit, two opposite sides of first side 41 and second side 42, forms the compressed part of protruding towards insulating body 21 directions 43, and the bottom surface at its compressed part 43 edges is provided with level and smooth fillet 431.During use, the compressed part 43 of pressing plate 40 contacts with wafer module 60, and when pressing plate 40 pushed downwards in the portion that exerts pressure 35 of shifting part 30, pressing plate 40 was pushed the conducting terminal 12 tight butts that wafer module 60 makes its conducting strip and electric connector 1 downwards by its compressed part 43.

Reinforced sheet 20 is the setting of lengthwise shape, and it comprises the side that links to each other in twos and extend upward the sidewall of setting from side, and sidewall adjacent with the second side 42 of pressing plate 40 during its assembling is a first side wall 22, with the first side wall 22 opposed sidewalls be second sidewall 24.Holding part 421 corresponding to pressing plate 40 on the first side wall 22 offers a pair of bayonet socket 221, this bayonet socket 221 fastens so that pressing plate 40 is articulated in reinforced sheet 20 with the holding part 421 of pressing plate 40, second sidewall 24 is provided with the retaining sheet 241 that a pair of bending is provided with, and be extended with retaining sheet 242 in the bending of an end of a retaining sheet 241, this retaining sheet 241 and retaining sheet 242 make shifting part 30 be articulated in second sidewall 24 of reinforced sheet 20 in conjunction with the end of the other two side of reinforced sheet 20, and are provided with semicircle arcuation boss 243 with locking shifting part 30 on a sidewall between the first side wall 22 and second sidewall 24 in it.Reinforced sheet 20 locating convex block 18 corresponding to insulating body 10 on the side at its first side wall 22 and second sidewall, 24 places is provided with recess 26.

This electric connector 1 assembling process is as follows: elder generation is articulated in pressing plate 40 and shifting part 30 respectively the first side wall 22 and second sidewall 24 of reinforced sheet 20, again pressing plate 40 is placed open position, then insulating body 10 is inserted in the reinforced sheet 20, locating convex block 18 by insulating body 10 bottoms be sticked in reinforced sheet 20 bottoms recess 26 so that insulating body 10 be immobilizated among the reinforced sheet 20, simultaneously the sidewall of reinforced sheet 20 be coated on insulating body 10 around.
