Embodiment
About aforementioned and other technology contents, characteristics and effect of the present utility model, in the detailed description of a following cooperation preferred embodiment with reference to the accompanying drawings, can clearly present.
Consult Fig. 3 and Fig. 4, the utility model electric connector 1 offers the chip module with a plurality of stitch, and (figure does not show, central processing unit (CPU) as stitch) use, the preferred embodiment of the utility model electric connector 1 comprises an insulating base 2 and a plurality of terminal 3.
Consult Fig. 5, Fig. 6 and Fig. 7, each terminal 3 comprises that a body 31, is connected and is electrically connected at elastic arm that the weld part 32 of a circuit board (figure does not show), two extend with respect to two relative sides of the other end of weld part 32 in the same way by body 31 33, two outward extending location divisions 35 of two opposite side edges from body 31, and two two relative sides that extend described elastic arm 33 respectively in body 31 and extend to the assistant spring arm 34 in described elastic arm 33 outsides in the same way with described elastic arm 33 with an end of body 31.
In the present embodiment, each terminal 3 includes two elastic arms 33 and two assistant spring arms 34, but each terminal 3 also can only comprise an elastic arm 33 and one and elastic arm 33 be positioned at the assistant spring arm 34 of same side.
Weld part 32 generally is vertical with body 31.Described location division 35 is in the same plane with body 31, and each location division has two hangnails 351.
Two elastic arms 33 (refer to the I direction) forward from body 31 respectively and extend, and relatively near be extended with a guidance part 331, be positioned at elastic arm 33 free-ended contact site 332, and one from contact site 332 turnovers and along the bearing of trend (referring to vertically) of body 31 toward the extension 333 that extends near weld part 32 directions.Two guidance parts 331 all are the inside arcuation of opening, and the spacing of the two is from dwindling gradually away from body 31 places near body 31 places are past.
Each assistant spring arm 34 is connected in body 31 places between the elastic arm 33 and weld part 32 of the same side.Each assistant spring arm 34 have a connecting portion 341 that extends along the I direction from body 31, and one from the end turnover of connecting portion 341 and along the bearing of trend of body 31 toward the assisted parts 342 that extends away from the direction of weld part 32.The free end of the assisted parts 342 of each assistant spring arm 34 is positioned at the outside of extension 333 of the elastic arm 33 of the same side.The spacing of two assisted parts 342 is from dwindling gradually away from connecting portion 341 places near connecting portion 341 places are past.
Consult Fig. 4 and Fig. 5, when terminal 3 was assembled to terminal hole 211, two location divisions 35 of terminal 3 were placed in two location notchs 213 of terminal hole 211.Because the thickness of location division 35 equates with the width of location notch 213, thereby can limit terminal 3 in being assembled to terminal hole 211 backs moving along the I direction.In addition, each location division 35 is formed with two hangnails 351, forms destruction interference with the cell wall with location notch 213 and fixes, and can limit terminal 3 moving up and down after being assembled to terminal hole 211.
Consult Fig. 3, Fig. 4 and Fig. 5, after chip module was installed in slip lid 22 by the top, each stitch passed in the terminal 3 that jack 221 enters terminal hole 211.Because the aperture of jack 221 and the equal diameters of stitch, so chip module can move simultaneously with slip lid 22.
When rotating drive part 23, can make slip lid 22 with respect to pedestal 21 along the slippage between non-locked position and latched position of I direction, and the stitch that makes the chip module that is installed in slip lid 22 simultaneously is along the slippage of I direction.
When non-locked position, stitch is positioned at two spaces that elastic arm 33 is surrounded of terminal 3, and does not contact with terminal 3.At this moment, stitch and terminal 3 do not electrically connect.
When latched position, stitch is subjected to the guiding of two guidance parts 331, contact site 332 direction slippages along the I direction toward elastic arm 33, because of the diameter of stitch spacing greater than two contact sites 332, so can promote two elastic arms 33 of two contact sites, 332 interlocks outwards opens, the extension 333 of elastic arm 33 is connected to is positioned at the assisted parts 342 of the assistant spring arm 34 in its outside, and then promote two assistant spring arms 34 and outwards open.So, make two elastic arms 33 and two assistant spring arms 34 provide elastic force to stitch simultaneously, and make stitch and terminal 3 stable contacts, reach electric connection.
In sum, design by two elastic constructions (elastic arm 33 and assistant spring arm 34), when making contact site 332 slippages of stitch past elastic arm 33 in terminal 3, can promote elastic arm 33 and be positioned at elastic arm 33 outer assistant spring arms 34 outwards to open, make elastic arm 33 and assistant spring arm 34 provide elastic force to stitch simultaneously, to provide bigger contact positive force that stitch is firmly contacted with terminal 3, and then signal stabilization is transmitted, can solve when the size of terminal is dwindled, because of elastic arm is easier to skew or distortion, loose contact and signal transmit unsettled situation.
Yet the above only is preferred embodiment of the present utility model; can not limit the scope that the utility model is implemented with this; be that all simple equivalent of doing according to protection range of the present utility model and description change and modification, all still belong in the protection range of the present utility model.
