Abstract

The utility model relates to a socket connector terminal mainly used for the zero insertion force socket of the central processing unit. The terminal comprises a base, two symmetrical contact parts obliquely extending from one lateral side of the base and a welding part oppositely extending from the other lateral side of the base, wherein, the terminal is provided with at least two bending lines in different directions and when the terminal is spread along the bending line to form a plane raw product of the terminal, the shape of the terminal is approximate to the word ''Y''. The contact part of the terminal comprises a head, an elastic arm and a contact edge. Compared with the current terminals of the same kind, the elastic arm of the socket connector terminal of the utility model has a longer extended length, thereby increasing the elasticity of the contact part to improve the mechanical property of the terminal.

Description

The socket connector terminal

[technical field]

The utility model is a kind of socket connector terminal, refers to that especially a kind of mechanical performance is strengthened and is applied to the Zero plug-in force socket terminal of CPU.

[background technology]

The socket connector terminal relevant with the utility model is mainly used in the CPU socket, and the one end is welded in circuit board, other end grafting CPU stitch.In use, the stitch of CPU is inserted in the socket connector terminal with zero insertion force, this moment, terminal can not produce distortion, after insertion puts in place, utilize push rod that the socket connector terminal is closely contacted with the CPU stitch, thereby circuit is able to conducting, and in this process, the socket connector terminal is out of shape generation owing to being squeezed.Because the existing socket connector terminal arm of force is shorter, stress is bigger, and this distortion may be plastic deformation, can not reply.In follow-up use, after stitch inserted and puts in place, because the socket connector terminal produces plastic deformation, stitch and socket connector termination contact position produced loosening, influence conduction stationarity.And CPU is to electrically having relatively high expectations, in addition its stitches are close, if it is improper to peg graft, then can damage stitch.

The main method that addresses this problem reduces the stress of termination contact arm for reduce the rigidity of termination contact portion as far as possible.Fig. 1 is a kind of existing Zero plug-in force socket terminal, elastic arm 94 and weld part 92 that it comprises base portion 90, is extended to both sides by base portion 90, wherein elastic arm 94 forms two spaces, be respectively free space 96 in order to ccontaining butt connector stitch of going into (not icon) with the zero insertion force group thereby and grasping part 98 guarantee good electrical the contact in order to closely contact with stitch.Stitch is introduced into free space 96, is then entered grasping part 98 and contact formation with the contact-making surface 940 of elastic arm 94 by the external force extruding to electrically conduct, and simultaneously, elastic arm 94 will produce distortion.Designed according to this electric connector terminal, elastic arm 94 arm of forces are shorter, clamp-on in grasping part 98 processes in stitch, and the stress that its root 941 bears is bigger, and the distortion that it produced may be plastic deformation, will influence terminal conduction stationarity.

[summary of the invention]

The purpose of this utility model is to provide a kind of to be had firm chucking power, guarantee the reliable contact of CPU stitch and is difficult for producing the CPU socket connector terminal of plastic deformation.

The purpose of this utility model is achieved in that the utility model provides a kind of socket connector terminal, and it is mainly used in the zero insertion force CPU socket.This terminal is one time punching molded by strip, comprise base portion, by base portion outward extending two symmetrical contact sites, with the tin ball weld part of circuit board welding, and the contact site of this terminal comprises head, elastic arm and contact edge.After this socket connector terminal punch forming, its semi-finished product shape approximation is in " Y " shape.Then, around the bending line bending that is parallel to the terminal center line, make two contact sites form an ambient its contact site, simultaneously the head of contact site is wound another bending line bending, make two heads form a grasping part perpendicular to above-mentioned bending line.She Ji contact site according to this, under the situation that does not increase width, length rises appreciably, improve termination contact portion mechanical performance thus, reduce stress, reduce the terminal rigidity, make termination contact portion be difficult for producing plastic deformation, guarantee that CPU stitch and socket connector termination contact are good, preferable electric connection is provided.

Compared with prior art, the utlity model has following advantage: because this terminal elastic arm is longer, make the suffered in the course of the work stress of termination contact portion less, make termination contact portion be difficult for producing plastic deformation, guarantee the excellent electrical property contact.

Fig. 3 is the utility model socket connector terminal and schematic perspective view after the CPU stitch cooperates.

Fig. 4 is the vertical view of Fig. 3.

Fig. 5, Fig. 6 are the schematic diagrames that the utility model socket connector terminal cooperates with the CPU stitch.

[embodiment]

See also Fig. 2, the utility model socket connector terminal 1 is by strip 2 punching press one-shot formings, comprises a base portion 10, by base portion 10 outward extending contact site 11 and weld parts 12.Wherein, contact site 11 comprises head 111, connects the elastic arm 112 of head 111 and base portion 10, and the profile side of head 111 is the contact edges 113 with chamfering.Between contact site 11 and weld part 12, by base portion 10 some protruding thorns 100 that stretch out, location when doing to install.

Please in the lump with reference to Fig. 3, with first bending line 41 bendings of contact site 11 around icon, make 112 of the elastic arms of contact site 11 form a free space 20, stitch 30 in order to ccontaining CPU of going into the zero insertion force insert group, second bending line 42 that the head 111 of contact site 11 winds approximately perpendicular to above-mentioned first folding line 41 bends to close weld part 12 directions, simultaneously its weld part 12 bendings is made it to be in base portion 10 the same sides perpendicular to base portion 10 and with contact site 11.By this kind design, under the situation that does not increase contact site 11 width, obviously increase the length of contact site 11, reduce contact site 11 rigidity, contact site 11 mechanical performances are improved, be difficult for producing permanent deformation.

Please refer to shown in Figure 4, when CPU stitch 30 is pegged graft with the utility model socket connector terminal 1, CPU stitch 30 is at first gone into the space of being encircled by contact site 11 20 with the zero insertion force group, at this moment, stitch 30 and termination contact portion 11 no any contacts promptly do not produce extruding force to contact site 11.

See also Fig. 5, CPU stitch 30 moves to head 111 directions near contact site 11 under external force, because the diameter of stitch 30 is greater than the distance of two heads 111 of contact site 11, so will pushing the head 111 of contact site 11, stitch 30 make elastic arm 112 produce strain, head 111 drives elastic arm 112 and opens to both sides, is the trend of holding CPU stitch 30.Because contact site 11 is longer, the stress that this moment, contact site 11 was born is less, and CPU stitch 30 more easily enters the clamping contact condition by free space 20.

See also Fig. 6, further organize with the stitch 30 of CPU, contact site 11 continues to open to both sides, and the stitch 30 of CPU connects with the contact edge 113 of contact site 11, and this moment, contact put in place.Because two heads 111 of contact site 11 constitute around the shape structure, it is loosening that this kind structure makes that the stitch 30 of CPU is difficult for, and guarantees its excellent electrical property contact.
