[embodiment]

Please together consult Fig. 1 to Fig. 5, the utility model electric coupler component 1 comprises electric connector 2 that electrically connects CPU module 4 and circuit board (not shown) and the sucking plate 3 that is mounted on electric connector 2.The pressing plate 24 that electric connector 2 mainly is located at the reinforced sheet 22 in connector body 21 outsides by the connector body 21 that is equipped with plurality of conductive terminals 212, bag and is connected to 21 liang of opposite ends of connector body is respectively formed with shifting part 25.

Connector body 21 is lengthwise tabular structure, its middle part is provided with conduction region 211, offer plurality of terminals accepting groove (not label) in conduction region 211, contain a corresponding conducting terminal 212 in each terminal containing slot, the surface that conducting terminal 212 protrudes in conduction region 211 connects in the mode of pushing with the conducting strip (not shown) with CPU module 4.

Connector body 21 away from the surface of circuit board in order to supporting CPU module 4, connector body 21 is electrically connected to circuit board by conducting terminal 212 and realizes electrically connecting with circuit board, finally realizes being electrically conducted of CPU module 4 and circuit board with being electrically conducted of conducting strip of CPU module 4 by conducting terminal 212 again.

Pressing plate 24 is a hollow framework, its central authorities form an opening 244, its two opposed side edges is first side 241 and second side 242, the middle part of first side 241 is protruded and has been extended to form

auxiliary section

2411,242 symmetries extend the holding part 2421 that two cross sections are the semicircle arcuation in the second side, extend the location division 2422 that roughly is strip between two holding parts 2421.

Sucking plate 3 is provided with substrate 31 and is roughly parallel to the smooth smooth flat board 33 of substrate 31, the two is connected by the sidewall facing each other 32 that upwards extends from substrate 31, be provided with fillet 321 simultaneously between each sidewall 32 to realize smooth connection, dull and stereotyped 33 with sidewall 32 between formation one receiving space 34 of back cover not, after sucking plate 3 was installed in electric connector 1, this receiving space 34 was towards electric connector 1.Substrate 31 is respectively equipped with first end 35 and the second end 36 corresponding to the first side 241 and the second side 242 of pressing plate 24, and when combined, substrate 31 is bottom surface (a not label) near the face of pressing plates 24 with pressing plate 24.First end 35 vertically protrudes out respectively in the bottom surface of its two opposite end and is provided with first trip 351, outwards the level extension is formed with trapezoidal extension 352 in its middle part, the second end 36 vertically protrudes out in the bottom surface at its middle part and is provided with a pair of second trip 361, is vertically installed with projection 362 respectively in the bottom surface of its two side ends.
