Embodiment
For better understanding spirit of the present utility model, it is described further below in conjunction with a preferred embodiment of the present utility model.
As shown in Figure 2, one is to be used for the socket connector planted for a cpu chip according to socket connector 1 of the present utility model.This socket connector 1 comprises an insulating body 2, a shielding casing 3, and plurality of conductive terminals 4.This insulating body 2 is provided with plurality of terminals accepting groove 5, and each conducting terminal 4 promptly is contained in the corresponding terminal containing slot 5 and sets up electrical connection to dock with CPU (not shown).
Shown in Fig. 3,4, with insulating body 2 towards a side of circuit board (not shown) for down, each terminal containing slot 5 is the rectangular poroid of pass through openings 50,51 up and down, has the relative the first side wall 52 and second sidewall 53.Connect this first side wall 52 and second sidewall, 53 formation one the 3rd sidewall 54 and the 4th sidewalls 55.Between this first and the 3rd sidewall 52,54, the second and the 3rd sidewall 53,54 extends one first limiting section 56, second limiting section 57 and draw-in groove 58 in opposite directions.In the present embodiment, this first and second limiting section 56,57 links together, and first limiting section 56 is for being formed at the first side wall 52 of terminal containing slot 5 and the limited step on second sidewall 53, the diapire of second limiting section, 57 formation draw-in grooves 58.
As shown in Figure 5, each conducting terminal 4 has two weld parts 40, a base portion 41, connects this two weld part 40 and the connecting portion 42 of base portion 41, the elastic arm 43 that is connected with base portion 41 other ends, reaches the contact site 44 that extends from this elastic arm 43.Concrete, it is tabular that this two weld part 40 is roughly gone up in vertical direction, and extend relatively the free end both sides of connecting portion 42 naturally respectively.Define one between the two and hold the welding space 45 (with reference to figure 8) that soldered ball S enters, to be used for that conducting terminal 4 is connected to circuit board.Two first holding sections 46 respectively from each weld part 40 upside mutually away from extension.Connecting portion 42 extends earlier vertically upward from an end that extends weld part 40, and the level bending extends welding 45 tops, space again.It is irregular tabular that base portion 41 is, and it extends upward from connecting portion 42 bendings, is extended with second holding section 47 from its relative both sides of about center.Elastic arm 43 repeatedly bends from base portion 41 upper ends earlier and extends upward, and contact site 44 promptly continues bending from this elastic arm 43 and extends.
Further combined with Fig. 6,7 (a), 7 (b), each conducting terminal 4 is with three sidewall 54 (promptly towards four sidewall 55) of base portion 41 by terminal containing slot 5, goes into for 50 groups from corresponding terminal containing slot 5 upper sheds.Weld part 40 is contained under shed 51 places, and elastic arm 43 is stretched on outside the upper shed 50 of terminal containing slot 5 with contact site 44.Base portion 41 both sides are stuck in the draw-in groove 58.First holding section 46 is crossed first, second limiting section 56,57 and is contained in below first limiting section 56 in organizing process, second holding section 47 is contained in second limiting section, 57 tops.In the present embodiment, second holding section, 47 lower edges and second limiting section, 57 upper surfaces all are designed to the chamfering shape, cooperate and the minimizing collision with convenient.So first, second holding section 46,47 of limiting conducting terminal 4 respectively by first, second limiting section 56,57 in the terminal containing slot 5 upwards, move down, make terminal 4 metastablely be immobilizated in the terminal containing slot 5 can not deviate from.
As Fig. 8, in actual the use, because when being soldered to conducting terminal 4 on the circuit board, soldered ball S enters welding space 45 and two weld parts 40 can be passed to both sides.Thereby leave certain clearance at two weld parts 40 and 52,53 of first, second sidewalls usually, avoid extruding to make terminal containing slot 5 distortion.
Socket connector of the present utility model is contained in the limiting section below that the terminal containing slot inwall is provided with by first holding section that is provided with on the conducting terminal, and second holding section is contained in the limiting section top, can prevent respectively that terminal from deviating from from terminal containing slot top, below.Than holding parts such as the protruding thorn cooperates with the terminal containing slot destruction interference, projection are set on the terminal in the prior art, can not cause that the stress on the insulating body is concentrated because of the destruction interference cooperation, can not influence the welding quality between socket connector and circuit board.Improve the stability that is electrically connected on the one hand, guarantee properties of product; Also improved the life-span of product on the other hand greatly.
Technology contents of the present utility model and technical characterstic disclose as above, yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and done all replacement and modifications that does not deviate from the utility model spirit.Therefore, protection range of the present utility model should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present utility model and modifications, and is contained by the present patent application claim.
