[embodiment]
See also Fig. 1 and Fig. 2, electric connector 1 of the present utility model is used for chip module (not shown) is connected to a circuit board (not shown), and it comprises a pedestal 8, be contained in the some electric installations 5 in the pedestal 8 and be positioned at the circuit board bottom is used for the fixture 6 of fixing pedestal 8.Pack into from pedestal 8 tops and be threaded into fixture 6 by bolt 7, thereby electric connector 1 is fixed on the circuit board.
Please be simultaneously with reference to Fig. 5 and Fig. 7, upper strata holding board 2 and lower floor's holding board 3 superpose up and down, and it is respectively equipped with corresponding through hole 20,30.Corresponding through hole 20,30 connects and forms the accommodation hole 21 that holds for electric installation 5 jointly.
With reference to Fig. 3 and Fig. 4, electric installation 5 comprises first electric conductor 50, second electric conductor 51 and the elastic rubber pipe 52 between first electric conductor 50 and second electric conductor 51.First electric conductor 50 and second electric conductor 51 are provided with base portion 500,510 respectively, outer conductive part 501,511 and interior conductive part 502,512.Wherein, base portion 500,510 extends to form outer conductive part 501,511 and interior conductive part 502,512 respectively in the opposite direction, and elastic rubber pipe 52 is provided with the passage 520 that supplies first electric conductor 50 and second electric conductor 51 to run through.Offering an interior conductive part 512 that has tube seat 503, the second electric conductors 51 of horn-like opening in the interior conductive part 502 of first electric conductor 50 is a conductive pole.When electric installation 5 is assembled to pedestal 8, the base portion 500,510 of first electric conductor 50 and second electric conductor 51 and interior conductive part 502,512 are arranged in accommodation hole 21, outer conductive part 501,511 protrudes outside the accommodation hole 21, to electrically connect chip module and circuit board respectively.In being inserted into, interior conductive part (conductive pole) 512 also electrically contacts in the tube seat 503 of conductive part 502 with the inwall of tube seat 503.First electric conductor 50 and second electric conductor 51 pass the passage 520 of elastic rubber pipe 52, be located between two base portions 500,510 and and apply elastic force, to keep the good electrically contact between electric installation 5 and external chip module and the circuit board to first electric conductor 50 and second electric conductor 51.When chip module is loaded to electric connector of the present utility model, can make by extra compression bonding apparatus in its host cavity that is fixed in framework 4 40.First electric conductor 50 relatively moves because of outer conductive part 501 is pushed with second electric conductor 51 by chip module, simultaneously elasticity of compression rubber tube 52.In this process, the inwall of the tube seat 503 of interior conductive part 502 keeps electrically contacting with conductive pole 512 all the time.
