Embodiment
In order better to understand 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, be to be used for it being electrically connected to circuit board P according to socket connector 1 of the present utility model for cpu chip C (seeing Fig. 4,6) plants.This socket connector 1 comprises insulating body 2, some conducting terminals 3 that is contained in this insulating body 2, be used for firmly compressing the press box 4 of the chip of insertion, and is installed on the base 5 that the circuit board P back side articulates press box 4.And in the present embodiment, this insulating body 2 is soldered on this circuit board P.
Shown in Fig. 3,4, this insulating body 2 is cuboid, and its middle part is provided with rectangular conductive district 20 to be used to accept the chip C of insertion.Be penetrated with plurality of terminals accepting groove 21 in this conduction region 20, accommodate corresponding conducting terminal 3.
This press box 4 further comprises framework 40 and depression bar 41.This framework 40 is corresponding with insulating body 2 shapes, has relative first side 42 and second side 43, and one group of the 3rd relative side 44 of two these first sides 42 of connection and second side 43.The outer rim centre position of this first side 42 is to the articulated section 421 of an arc of this second side 43 directions bending.The outer rim of this second side 43 is interval with the holding section 430 of a pair of tab-like, and distolateral to being convexly equipped with stopper section 431 with one the 3rd side 44 adjacency.Two the 3rd sides 44 have first support arm 440 that connects first side 42 respectively, with second support arm 441 that is connected second side 43.These first support arm, 440 positions are low than second support arm 441, and length is than the length of second support arm 441; Thereby forming a ladder-type structure 442 near 43 places, second side, i.e. the plane, two first support arms, 440 place that joins with it, this first side 42, yet reach plane, two second support arms, 441 place that this second side 43 joins with it not coplane be parallel to each other.This depression bar 41 articulates to be located on the framework 40, comprises drive-connecting shaft 410, vertically bends the power transmission shaft 411 of extension from drive-connecting shaft 410 1 ends, and bend the L shaped lever 412 of extension from these power transmission shaft 441 other ends.The one section bending in these drive-connecting shaft 410 middle parts is protruding in a side, is one to be contained in the portion that exerts pressure 413 of the articulated section 421 of framework 40.This power transmission shaft 411 is to extend the side that framework 40 is provided with stopper section 431 with lever 412.
This base 5 is a plate-like structure, and corresponding first end 50 of the first side 42 of its corresponding framework 40, second side 43, second end 51 are respectively equipped with a pair of pin joint seat 52 and a pair of trip seat 53 with bayonet socket 530 that articulates mouth 520 that have.Wherein this pin joint seat 52 can match with the drive-connecting shaft 410 of this depression bar 41, and this drive-connecting shaft 410 can articulate in mouthfuls 520 at this and rotate, thereby reaches this portion's 413 pressings or separate the effect of this press box 4 of exerting pressure; This trip seat 53 then can articulate with this holding section 430.In the present embodiment, to should pin joint seat 52 with trip seat 53, offer corresponding installing port P0, P1 on the circuit board P.Can on this base 5, offer other fixing hole 54 according to the needs of other elements (not shown) such as installation radiator in addition, make this base 5 play the effect of backboard.
As shown in Figure 5, during assembling, at first conducting terminal 3 is inserted in the terminal containing slot 21 of this insulating body 2, the weld part of this conducting terminal 3 (not shown) can directly be soldered on the circuit board P, so corresponding insulation body 2 also is assembled on the circuit board P.Pin joint seat 52 with base 5 passes corresponding installing port P0, P1 with trip seat 53 then, then 410 groups of the drive-connecting shafts of this depression bar 41 are gone in the pivot joint mouth 520 of pin joint seat 52, rotate this depression bar 41 and make 411 one-tenth vertical states of this power transmission shaft this moment, and the bayonet socket 530 of trip seat 53 can just in time be aimed in the holding section 430 of this press box 4.Then the power transmission shaft 411 of this depression bar 41 is stirred to horizontal level, this framework 40 produces under the effect of depression bar 41 and moves horizontally, and these holding section 430 levels are advanced in the buckle 530 of this snap seats 53, finishes the assembling process of this press box 4 and base 5; Thereby this socket connector 1 is fixed on the circuit board P.
When reality is used, only chip C need be positioned in the conduction region 20 of this insulating body 2 in advance, and then the installation of carrying out base 5 and press box 4 cooperates and gets final product.As Fig. 6, the chip C of butt joint is inserted the conduction region 20 of insulating body 2, rotating operation handle 412 is pushed to circuit board P direction, drives drive-connecting shafts 410 pivot in the pin joint seat 52 of the articulated section 421 of framework 40 and base 5 by power transmission shaft 411; The portion 413 that exerts pressure turns to articulated section 421 gradually and exerts pressure to it in the pivot process, and then makes framework 40 push chip C gradually.As shown in the above, on this first support arm 440 height and position different, therefore have only first support arm 440 of the 3rd side 44 can compress chip C, it is firmly docked with conducting terminal 3 with second support arm, 441 offices; Promptly this moment, second support arm 441 did not compress with chip C, but because the length of this first support arm 440 is greater than the length of this second support arm 441, in conjunction with the acting in conjunction of this first side 42, consider simultaneously, can reach the purpose of this chip of held stationary C from the stress balance angle; Continue the application of force and cross the stopper section 431 of framework 40 until the lever 412 of depression bar 41.Stop the application of force this moment, and power transmission shaft 411 remains on this location because of the backstop of stopper section 431, thereby realizes covering of this chip C and socket connector 1.In the present embodiment, because the existence of base 5 makes that the subsequent installation radiator is more convenient, can reach the radiator fixation by load radiator and the fixing effect by the fixing hole 54 that is provided with on the base 5 at chip surface.
Socket connector 1 of the present utility model, its base 5 is the back side that is installed on circuit board P, when having firm mounting receptacle connector 1 effect, this base 5 can make full use of the backboard fixation of this base 5 when the subsequent installation heat abstractor; The saving element reduces cost, and has avoided in the welding process warpage influence to insulating body 2.In addition, the framework 40 of press box 4 is provided with stopper section 431, with depression bar 41 interlockings, has guaranteed that butt joint chip C docks with the firm of conducting terminal 3.
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.
