[embodiment]
See also Fig. 1, the present invention relates to a kind of low insertion force type socket connector 10, mainly in order to electrically connect chip module (not shown) and printed circuit board (PCB) (not shown), it comprises insulating body 20 and the plurality of conductive terminals 30 that is placed in the insulating body 20.
Describe each parts of low insertion force type socket connector 10 of the present invention in detail below in conjunction with accompanying drawing.See also Fig. 1 and Fig. 5 to Fig. 7, insulating body 20 is the rectangular plate shape structures by the insulating material moulding, and it is provided with the supporting surface 202 of supporting chip module and the installed surface 204 that is connected printed circuit board (PCB).Four drift angles of installed surface 204 are respectively equipped with contour back-up block 205, can prevent that socket connector 10 relative printed circuit board (PCB) when welding from producing the welding quality during with the assurance welding.
Run through terminal containing slot 206 and stitch guide channel 208 that supporting surface 202 and installed surface 204 are provided with some mutual conduction, guide channel 208 comprises and is the guidance part 210 of being inverted frustum and the connecting portion 212 that is connected guidance part 210 and terminal containing slot 206.It is poroid that connecting portion 212 is cylinder, its aperture be slightly larger than chip module stitch 50 diameter and less than the level interval D of 30 liang of contact sites 3080 of conducting terminal, can in the grafting process of chip module stitch 50, guide stitch 50, make things convenient for stitch 50 to insert in the terminal containing slot 206 smoothly.For improving 50 groups of fashionable normotopia degree of chip module stitch, the footpath needs less than footpath within the terminal containing slot 206 within the guide channel 208.
In conjunction with consulting Fig. 2, Fig. 3 and Fig. 4, conducting terminal 30 is to be formed through forging and pressing, punching out by metal sheet, it comprises base portion 302, a pair of arm 304 that extends relatively from base portion 302 both sides respectively, is arranged at the contact site 3080 on arm 304 tops, and the weld part 306 that is positioned at base portion 302 lower ends.
It is straight tabular and extend in vertical direction that base portion 302 is, and its upper end and middle part are respectively equipped with a pair of hangnail 3020, in order to conducting terminal 30 stably is immobilizated in the terminal containing slot 206 of insulating body 20.Weld part 306 is to be formed through bending by base portion 302 lower ends, and it is straight tabular and generally along perpendicular to base portion 302 direction horizontal-extendings.Be implanted with tin ball 40 on the weld part 306, in order to conducting terminal 30 corresponding being welded on the printed circuit board (PCB).
The development length that setting can increase arm 304 is extended in the bending of conducting terminal 30 arms 304, improves the elasticity of arm 304; The contact site 3080 of conducting terminal 30 is smooth cambered surface setting, can make things convenient for the plug of chip module stitch 50.
Describe the assembling process of low insertion force type socket connector 10 of the present invention in detail below in conjunction with accompanying drawing, see also Fig. 6 and shown in Figure 7, conducting terminal 30 inserts in the corresponding terminal containing slot 206 from bottom to top, the base portion 302 of conducting terminal 30 is resisted against on the cell wall of terminal containing slot 206, the hangnail 3020 that extends from conducting terminal 30 base portions 302 both sides and the sidewall interference engagement of terminal containing slot 206, thus conducting terminal 30 stably is immobilizated in the corresponding terminal containing slot 206.When conducting terminal 30 was located in the terminal containing slot 206 fully, there were a determining deviation in the top in the vertical direction of the contact site 3080 of conducting terminal 30 and connecting portion 212.
Describe use, the operating process of low insertion force type socket connector 10 of the present invention in detail below in conjunction with accompanying drawing, please in the lump with reference to figure 5 and shown in Figure 6, at first, by the tin ball 40 of planting on conducting terminal 30 weld parts 306 low insertion force type socket connector 10 is installed on the printed circuit board (PCB); Then, the chip module is placed on the low insertion force type socket connector 10, its stitch 50 respectively and corresponding guide channel 208 correspondences; At last, pressing down the chip module makes the stitch 50 of chip module borrow the guiding of guidance part 210 to enter connecting portion 212 and insert in the corresponding terminal containing slot 206.After contact site 3080 butt joints of the stitch 50 of chip module and conducting terminal 30, continue to move down along the arc smooth contact surface, and electrically conducting of finally between chip module and printed circuit board (PCB), forming.
In conjunction with above-mentioned use, operating process, when the stitch 50 of chip module produces deflection with respect to normal insertion position, borrow the guiding of guide channel 208 and the smooth cambered surface setting of conducting terminal 30 contact sites 3080, the deflection of chip module stitch 50 can be corrected, thereby can guarantee the smooth grafting of the stitch 50 and the conducting terminal 30 of chip module.
