Description

The terminal of zero insertion force Connection Block

The utility model relates to a kind of terminal of zero insertion force Connection Block, particularly a kind of terminal of simply constructed zero insertion force Connection Block.

As shown in Figure 1, it is the stereogram of the terminal of Taiwan application case number No. 83214436 patent case zero insertion force Connection Block, this terminal comprises a butting section 11, a pitch of the laps portion 12 and a pin portion 13, this pitch of the laps portion 12 be from the butting section 11 lower ends to a side pitch of the laps, this pin portion 13 bends downwards from the 12 leading portion punching presses of pitch of the laps portion, make pitch of the laps portion 12 leading portions form a patchhole 122, a folder hole 123 and a perforate 124, the width of this patchhole 122 and perforate 124 is 0.8mm, the width 0.5mm of big what CPU pin, the width of this folder hole 123 is width of the little what CPU of 0.35mm pin, so this CPU pin can be gone into by these patchhole 122 0 intercalations, push folder hole 123 again and come the clamping location.

In the terminal of above-mentioned zero insertion force Connection Block, this pitch of the laps portion 12 is following direction one side and the top pitch of the laps by butting section 11, and pin portion 13 presses downwards from pitch of the laps portion 12, so, more complicated all in structure and manufacturing.

Main purpose of the present utility model is to provide a kind of terminal of zero insertion force Connection Block, has the good clamping effect of elasticity, and textural simpler.

For achieving the above object, the terminal that the zero insertion force that the utility model proposes connects is with a drawing of sheet metal, comprise a butting section, a pitch of the laps portion and a pin portion, broad is compared in this butting section, can be used as positioning action, this pitch of the laps portion by upper end, this butting section to a side pitch of the laps, be provided with the opening that equidirectional extends above, to before the patchhole of one section big what CPU pin width and the folder hole of one section little what CPU pin width being set, this pin portion extends in the below of this butting section to this opening by the back.

The terminal that the utility model proposes can be assembled in the slot below the Connection Block, and this CPU pin can be entered by the patchhole of pitch of the laps portion, when being passed toward the folder hole place, and can be by the folder hole resilient clamp.

That is to say, the utility model proposes a kind of terminal of zero insertion force Connection Block, be to be shaped by the sheet metal integrated punching, comprise the butting section of a shape than broad, one from the pitch of the laps portion of this upper end, butting section to a side pitch of the laps, a pin portion that extends in below, this butting section, its feature is at what: this is provided with the opening of equidirectional extension above butting section, this opening by the back to before being provided with the patchhole of one section big what CPU pin width and the folder hole of one section little what CPU pin width.

This pitch of the laps portion tail end is open, and the both sides of this opening are highly different high and low.

The patchhole place of this pitch of the laps portion is provided with twice formula beveled edge.

This direct punching press in folder hole both sides does not have vertical folder edge.

This opening is at the big what CPU of width of the front end of this folder hole pin width.

The upper end punching press of this butting section forms one and pushes against sheet.

In sum, the pitch of the laps portion of the terminal of the utility model zero insertion force Connection Block extends upward from the butting section, and pin portion directly extended downwards by the butting section, not only rubber-like clamping effect, and structure and make simple.

Be elaborated below by most preferred embodiment and accompanying drawing terminal to the utility model zero insertion force Connection Block, in the accompanying drawing:

The stereogram of Fig. 9 the utility model the 5th embodiment.

The Li Bentu of Figure 10 the utility model the 6th embodiment.

Shown in Fig. 2,3, present embodiment is the terminal of the zero insertion force Connection Block of slab pattern, utilizes the drawing of sheet metal of the about 0.35mm of thickness, comprises a butting section 21, a pitch of the laps portion 22, and a pin portion 23, and its feature is at what:

There is 1.92mm at the wideest position of this butting section 21, and is bigger than the slot width of Connection Block, can closely cooperate with the slot of this Connection Block when packing slot into, and the location.

This pitch of the laps portion 22, by the upper end of this butting section 21 to a side pitch of the laps, roughly be vertical configuration, be provided with the opening of equidirectional extension above, this open back end is open, be provided with the patchhole 221 of one section big what CPU pin width and the folder hole 222 of one section little what CPU pin width to the front by the back, this folder hole 222 extends to the lengthwise position of butting section 21, and this butting section 21 is provided with perforate 223.In addition, there is a folder edge 224 both sides of this folder hole 222, and this folder edge 224 is that direct punching press is come out, to avoid crushing the pin of CPU.The width of general CPU pin is 0.5mm, so this patchhole is 0.8mm, this folder hole is 0.35-0.4mm, and this perforate 223 is 0.6mm.This pin portion 23 is the belows that directly extend to this butting section 21, and width is 0.6mm.

The utility model embodiment is that whole row's terminal center distance 2.54mm is connected on the strip 4 on making, and behind the slot of the Connection Block of packing into, fractures from broken line 41, so the once row's of putting in order assembling in the combination.

Shown in Fig. 4,5, the utility model is assembled in the slot 421 of following of Connection Block, this butting section 21 can with slot 421 driving fits, when CPU is connected Connection Block, CPU pin 51 can be inserted by the patchhole 221 of pitch of the laps portion 22, when being passed by past folder hole place 222, and just can be by flexibly clamping of folder hole 222.

As shown in Figure 6, be second embodiment of the present utility model, this pitch of the laps portion 22 forms highly different high and low 225,226 when bending, can make folder hole 222 can fill part when the pin of clamping CPU and reach the contact effect, making in the electronic component connection of high precision to have good connection effect.

As shown in Figure 7, be the 3rd embodiment of the present utility model, the patchhole of this pitch of the laps portion 22 221 is provided with the beveled edge 227 and 228 in first and second road toward folder hole 222 places, and the pin that makes CPU can segmentation when entering folder hole 222 enters and more smooth and easy.

As shown in Figure 8, the 4th embodiment of the present utility model, it is a kind of pattern of thin plate, adopt the sheet metal integrated punching of the about 0.2mm of thickness to be shaped, wherein these pitch of the laps portion 22 pitch of the laps are to the lower end, and being against butting section 21, the rear end of this patchhole 221 can extend to the tail end of perforate 229 up to pitch of the laps portion 22.

Big with the metallic elastic of slab pattern by what, so pitch of the laps length does not need oversizely just have chucking power, and the metallic elastic of thin plate pattern is little, thus need long pitch of the laps length, and have the long opening could flexible good clamping effect.

As shown in Figure 9, be the 5th embodiment of the present utility model, it is a kind of thin plate pattern, this pitch of the laps portion 22 is when stamping out opening, fold a slice in the reservation of connection 21 places, butting section to pitch of the laps portion 22 1 sides and push against sheet 201, when the pin of clamping CPU, this pushes against the pin that sheet 201 can touch CPU, is used for the contact-enhancing effect.

As shown in figure 10, be the 6th embodiment of the present utility model, it is a kind of thin plate pattern, can cooperate the Connection Block of high density of terminals, shape is narrower and small, around pars convoluta 32 from tail end around 31 patchholes 321 that are respectively equipped with one section big what CPU pin width to the butting section, the wide 0.65mm of patchhole, the folder hole 322 that one section little what CPU pin is arranged, width are the perforate 323 of a 0.35mm and a big what CPU pin width, and width is 0.65mm.
