Abstract

The utility model provides an improved terminal for high-density connectors with stable and reliable insertion and conduction. A plurality of terminals are arranged on a tablet by integration punch forming. The upper part of each terminal is connected by surplus tablet strips, and a wedge structure with a plurality of heads inserting in the slots of a foot seat integrally and simultaneously is formed. A broken incision is arranged between each terminal and the surplus strips. A vertical pin is arranged along the extension direction of each terminal. The utility model is characterized in that each terminal body arranged on the upper section of the vertical pins is punched with two symmetrical side guide vanes curved inwards, a U-shaped structure is formed by the terminal bodies and the side guide vanes, the side guide vanes of the terminal bodies are punched with spring vanes convex to the side convex direction of the side guide vanes within the length of the side guide vanes, each spring vane and two symmetrical side guide vanes are inserted with the pin of a CPU, and the conducting state of three-point contact is formed.

Description

The modified model terminal of high-density connector

The utility model relates to a kind of modified model terminal of grafting device, particularly a kind of high-density connector.

The structure of the terminal of high-density connector as shown in Figure 1 to Figure 3 at present.Upper end one skew back of this terminal 12 is to inwardly protruding out a guide card 124, and extend a vertical pin 123 on the terminal body vertically downward, terminal 12 is by a whole strip punch forming, form the sheet upper punch at strip and set out some intervals terminal 12, after the slot 2 with the runners of central processing unit inserts, then can fracture by the incision that fractures, strip is separated with terminal, when the pin 3 of CPU is inserted in the embedding slot 2 again, can form the contact conducting state.Referring to Fig. 2 and Fig. 3.Structure by above-mentioned terminal is not difficult to find out, its contact conducting is by pin 3 pushing and plugging and realize with contacting of oblique guide card 124 forward, and, this contact is unidirectional, the card wedge of asymmetric shape, so, its compactness is not enough, and easily makes pin loosening and influence the grafting effect and connect effect.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, and provides a kind of grafting with multiple spot contact tight, is difficult for loosening and has the modified model terminal of the high-density connector that well connects effect.

The purpose of this utility model is to realize by following technical scheme:

Integrated punching forms several terminals on a tablet, and link to each other by remaining strip between the top of each terminal and constitute the structure of the slot mutual wedge anchorage of holistic bull simultaneously and runners, each terminal and residue all have the otch that fractures between the tablet, the bearing of trend of each terminal has a vertical pin, it is characterized in that: the terminal body upper punch at vertical pin epimere is provided with the two symmetrical side guiding plates that bend inwards, then guide card and terminal body constitute the Qian structure, in the length of the side guiding plate of terminal body, dash and be provided with a shell fragment to side guiding plate side convex direction projection, the join embedding and constitute at 3 and contact conducting state of the elasticity side guiding plate of shell fragment and two symmetries and the pin of CPU.

Therefore remarkable result of the present utility model is as follows:

The the 1st: owing to dash bending side guiding plate and the shell fragment that is provided with two symmetries, make the pin of CPU closely plug together and to be 3 conductings and contact shape with the Qian shape portion of terminal, therefore, not only has bigger contact-making surface and friction clamping power, and, have the reliability in the connection of multiple spot conducting simultaneously contact,, have the fine effect that connects again after grafting so the CPU pin both had been difficult for getting loose.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing:

Fig. 1 is the structural perspective of existing terminal;

Fig. 2 is the generalized section of Fig. 1 when pegging graft;

Fig. 3 is the generalized section after Fig. 1 pegs graft;

Fig. 4 is user mode figure of the present utility model;

Fig. 7 is terminal shown in Figure 6 and the runners slot profile when plugging together;

Fig. 8 is the utility model and the CPU pin profile when inserting embedding;

Fig. 9 is the profile after the utility model and CPU pin are inserted embedding;

Be described in detail below in conjunction with 4 to 9 pairs of concrete structures of the present utility model of accompanying drawing:

One tablet is a matrix band 1 through punch forming, have on the matrix band 1 a plurality of separately, and the terminal 12 that protrudes out to a side that laterally links together by top residue strip 11, dash between each interval terminal 12 and the matrix band 1 and be provided with the broken otch 13 that fractures in back of pegging graft, the hypomere of each terminal 12 has the pin 123 that plugs together mutually with the runners slot, it is characterized in that: be provided with in the upper terminal body upper punch of the pin 123 of terminal 12 and be vertical with body and to the side guiding plate 121 of two symmetries of the same side bending, protrude out the direction shell fragment 122 identical with side guiding plate 121 overbending directions towards being provided with in having the terminal body length of side guiding plate 121, the side guiding plate 121 of shell fragment 122 and two symmetries constitutes multiple spots with the pin 3 of the CPU that inserts and contacts shape.Referring to Fig. 4 to Fig. 9

The side guiding plate 121 of two symmetries is with the body of terminal 12 The type bending, oblique introduction segment 1211 outside the leading portion of two side guiding plates, 121 projectioies has slightly, side guiding plate 121 is the slightly inward inclined of symmetry

The resilient clamp shape of shape, shell fragment 122 are to dash the inside perk in a lower end that sets out and the ligule plate that the upper end links to each other by the terminal body one, and the upper edge of side guiding plate 121 offers recessed gap 1212.Referring to Fig. 6 to Fig. 9

Shown in Figure 4 is that a plurality of slots of representing the runners of the utility model and central processing unit plug preceding position view, whole runners A is fastened by a pedestal A1, a drive stay A2 and a sliding panel A3 and forms, surface distributed at pedestal A1 has several slots 12, and at each slot 12 1 side block A12 that all raises up, and on sliding panel A3 surface, also be distributed with several jacks A31.These all belong to prior art, so do not describe in detail.And after the utility model and its grafting, just fracture and each terminal is separated.
