Abstract

The utility model relates to an elastic clamp of a connecting seat. The utility model is used for connecting circuits of a central processing unit (CPU) of a computer. When the elastic clamp is unfolded, the upper end of a basal part of the elastic clamp is extended upwards to form an auxiliary part, and the lower part of the basal part is extended to form an inserting pin; the upper end (or the lower end) of the basal part is extended upwards or downwards to form a bending part; the auxiliary part, the bending part and the inserting pin remain to be on the same plane with the basal part, wherein, the upper end of the bending part is transversely extended toward a clamping part at the upper end of the auxiliary part to form a clamping part, and the two clamping part remain on the same central line. The spacing between adjacent elastic clamps which are bent to be processed by the structure is approximately equal to the spacing between slot seats of a connecting seat. The elastic clamp of a connecting seat can reduce the procedure of assembly and combination and save materials.

Description

Resilient socket for electricity contact

The utility model relates to the Connection Block elastic clip that circuit connects usefulness, particularly a kind of Connection Block elastic clip that is used in the connection of computer CPU (CPU) circuit.

The Connection Block that computer CPU (CPU) circuit connects is to plug several fixing equidistant elastic clip in the Connection Block body, this kind elastic clip provides the stitch of clamping CPU, makes the circuit of CPU be able to be communicated with other element circuitry by the contact pin of elastic clip lower end.Existing Chang Yong column type elastic clip, because of its complex structure, processing are difficult for, cost is expensive and can not popularize (see figure 1); And sheet type elastic clip (see figure 2) commonly used, because when it is continuous metal sheet type, the spacing (D) of its adjacent metal sheet center line is all greater than the spacing (2.54mm) of CPU stitch, it must just can be combined into the elastic clip that is nested with of same ranks groove seat through the secondary assembly program, so take a lot of work, and during with continuous metal sheets such as stamped, waste material is many, and is very uneconomical; In addition as seen from Figure 2, because of its clamping part is a plane configuration, so itself and contacting to point contacts that the CPU stitch forms, it is not high to connect the connection quality certainly.

The purpose of this utility model is to improve sheet metal type elastic clip structure, and its assembling is simplified, and it is few to take material during making, thereby saves man-hour, improves work efficiency, saves cost.

The purpose of this utility model is achieved in that and includes base portion 3, assisted parts 1, the Connection Block elastic clip of kink 2 and contact pin 4, its base portion 3 upon deployment, assisted parts 1, kink 2, contact pin 4 all remains on same plane, and contact pin 4 is formed by the lower end extension downwards of base portion 3, feature of the present utility model is: its assisted parts 1 is extended upward by the upper end of base portion 3, its kink 2 by the upper end (or lower end) of base portion 3 upwards (or downwards) extend, the clamping part 11 that one horizontal expansion is arranged in the termination of assisted parts 1 and

kink

2,21, and this two clamping part remains on the same center line, both side edges at base portion 3 is provided with the standing shape tenon 31 of locating usefulness in Connection Block groove seat A2, and the width of base portion equates approximately with the seat groove of Connection Block.

After adopting said structure with the kink bending, tenon by base portion just can be placed and be positioned in the groove seat of Connection Block easily, make the correctly corresponding inserting hole below of Connection Block that is arranged at of clamping part (referring to Fig. 6,7), and because of rough equating of groove seat of width with the Connection Block of base portion, when therefore above-mentioned sheet metal forms the continuity sheet metal with impact style, the center distance of its adjacent metal sheet can be set with the spacing (2.54mm) of CPU (CPU) stitch and equate, when this just makes punch forming, its adjacent center spacing can keep less, so that the material consumption is little, economical, and plant the combination operation that elastic clip is assembled in same ranks groove seat thus, only need once assembling just can finish, want the saving of labor than existing secondary assembling, hour, so the efficient height.

With drawings and Examples the utility model structure is further narrated below.

Figure 12 is the exploded view of Figure 11.

Figure 13 is that the clamping part of elastic clip is implemented illustration.

Shown in Fig. 5,6, be provided with some corresponding CPU(B in the upper surface of Connection Block (A)) inserting hole (A1) of stitch, then form the groove seat (A2) of rectangular cylindricality in the below of this inserting hole (A1), therefore, this Connection Block (A) is just like the form as the honeycomb.

By Fig. 7 embodiment 1 as seen, elastic clip (C) is to be provided with assisted parts 1 and kink 2 in base portion 3 upper ends basically, and form the clamping part 11 that mutual correspondence plays clamping action in the upper end of above-mentioned assisted parts 1 and kink 2 simultaneously, 21, be provided with the tenon 31 of standing shape in the both side edges of base portion 3, the lower end of base portion 3 is extended with contact pin 4, when elastic clip C is assembled among the groove seat A2 of Connection Block A, as Fig. 9, shown in 10, elastic clip C can be positioned among the groove seat A2 according to tenon 31, and make

clamping part

11,21 inserting holes (A1) below corresponding to Connection Block (A), as CPU(B) stitch in inserting hole (A1) insertion groove seat (A2) time, its clamping

part

11,21 couples of CPU(B) clamping of stitch contact.

Among the embodiment 1 shown in Figure 7, its kink 2 is extended upward by the upper end of base portion 3, then kink 2 is extended by the lower ends downward of base portion 3 among the embodiment 2 shown in Figure 11,12, still the schematic perspective view with Fig. 7 is identical after its bending, and its action effect is also identical.

By Fig. 8,13 as seen, in order to make CPU(B) stitch contacts with elastic clip, peg graft conveniently, can be provided with at clamping

part

11,21 and insert guide part 111,211 and vertical arc groove 112,212, thereby the some contact of the clamping part in the prior art is improved and is the face contact of applying closely.

In sum, the elastic clip of this creation is a continuity sheet metal form before bending and forming, the center distance of its adjacent metal sheet can be made as with the stitch spacing of CPU and equate, and the both side edges of base portion is provided with tenon, so can be positioned over easily in the groove seat of CPU Connection Block after its bending, correctly to being positioned at the inserting hole below, and the elastic clip assembly program is simple, the sheet metal waste materials in stamping is few, thereby can improve work efficiency greatly, reduce cost, the improvement of clamping part in addition contacts more it and fits with the CPU stitch.
