Description

The relay Connection Block of improvement

The utility model relates to the relay Connection Block, refers to a kind of have independently needle plate and general bottom especially, can reduce the fraction defective of formed product, and can promote the new-type structure of assembling mobility.

Advanced relay Connection Block commonly used, as shown in Figure 6, adopt metal connecting sheet to link to each other between its terminal base and relay jack, the bottom 3 of butt joint is provided with the cruciate cylinder 313 of equivalent and strengthens the holding capacity that it is inserted with the bottom of bracketing brace 2, assembling is comparatively convenient in the design, can save artificial, and distribution planning can be tending towards orderliness in the seat, and brace 2 is had establish thin advantage relatively, so help the functional need of following Connection Block miniaturization, only there is following shortcoming on its structural design: 1, its bottom 3 is except that the centre is provided with the protruded stigma body 313 of equivalent, need respectively be provided with two row's terminal cross square cylinders 313 in both sides, 312, two row's cross square cylinders 313,312 need establish hole slot 4 than long and top supplies pre-reason nut 41, so whole bottom 3 present one long take out do not wait body, cylinder is easy to generate contraction distortion when making ejection formation, causes the raising of fraction defective.2, cross square cylinder 313 quantity set on the bottom 3 of moulding are certain, can only be applicable to single specification product, can't be suitable in other kind of specification, so can all need special in addition configuration one bottom 3 for use to each different pins purpose Connection Block, the integral production mould expends quite huge and adds handling of goods and materials again and store people's trouble.

The purpose of this utility model is to provide a kind of being convenient to manufacture, and can reduce die cost, improves acceptance rate, and the new-type relay Connection Block that assembling again can the various different size of general replacement.

For reaching above-mentioned purpose, the utility model mainly comprises: a housing.One needle plate and a bottom are characterized in:

One upper shell, which is provided with the relay jack, two side ends is provided with the terminal Connection Block of step shape, and be divided into the several terminals position with baffle region, each terminal position is provided with the indent perforation with an embedding nut, shell wall place, class turnover position in the phase contraposition establishes one runs through the slit, for a metal contact pin is set, is provided with hole clipping at the upper shell downside between each terminal position and jack;

One needle plate, be independently individual movable being inserted in the upper shell, which is provided with the jack of several long columns with corresponding upper shell relay, the long column front end is provided with the footpath of the inserting metal connecting sheet bottom prominent point that contracts, with the front end of the long column bottom support as each jack metal connecting sheet;

One bottom, for being suitable for the hollow plate body of upper shell bottom opening, its side is provided with the card post and buckles mutually with the hole clipping of upper shell and combine, and when covering mutually needle plate is pushed against to place in the upper shell.

Can in upper shell, be provided with in the said structure design and establish the contraposition post on registration holes and the needle plate, make both in conjunction with the time can guarantee accurate contraposition.

The utility model has the advantages that: be provided with hole clipping and bottom opposite side position at upper shell and be provided with the card post and give and docking, mounting or dismounting are convenient; Needle plate is a small-sized separate component Connection Block, and the product of different size as long as replace to the Connection Block of different size, is promptly replaced suitable needle plate and can be finished, and bottom all can be general, helps making producing motor-driven allotment, reduces production costs.Be provided with registration holes in upper shell, needle plate is provided with the contraposition post, makes both in conjunction with guaranteeing accurate contraposition.

Form and technical characterictic for further introducing structure of the present utility model, the conjunction with figs. introduction, describe in detail as after.

At first see also shown in Figure 1ly, the relay Connection Block of the utility model improvement mainly is made up of a upper shell 1, a needle plate 2 and a bottom 3; Be characterized in:

One upper shell 1, below be provided with the hollow shell of opening 11, its housing is provided with relay jack 12, both sides are provided with the terminal Connection Block 13 of step shape, separate out several terminals position 132 therebetween and with dividing plate 131, each terminal position 132 is provided with indent perforation 133 with an embedding nut 134, is provided with one at relative place, class turnover position and runs through slit 14, metal connecting sheet 4 can be passed thus, and side is provided with hole clipping 15 and covers butt joint for bottom 3 under upper shell 1 again.

One needle plate 2, be movable being inserted in the upper shell 1 of separate component that is equipped with several long columns 22 on the flat board 21, the quantity of long column 22 is counted corresponding to the jack 12 of upper shell 1, and with the bottom support of long column 22 front ends as each jack metal connecting sheet 4, to increase the holding capacity that metal connecting sheet 4 is inserted.

One bottom 3 is one to be suitable for the hollow plate body of upper shell 1 bottom opening 11, and its side is provided with card post 31 and can buckles mutually with the hole clipping 15 of upper shell and combine, and just needle plate 2 can be pushed against when both cover mutually to place in the upper shell 1.

During combination as shown in Figure 2, imbed nut 134 in each terminal position 132 indents perforation 133 earlier, again in terminal position 132 and jack 12 metal connecting sheet 4 is set, metal connecting sheet 4 is for being different many folding shapes of dodging mutually, being provided with perforation 41 square end 42 can be by 14 passing through the slit in the upper shell, be fixed on the terminal position 132 with pad and screw, other holds one curves intermediate plate 43 is filled in the position of leaving a blank of jack 12.Treat to establish one by one appropriate after as shown in Figure 3, room under needle plate 2 alignment receptacles 12 is inserted, contract with set footpath, long column 22 tops and prominent select 23 and insert the square frame 44 that intermediate plate 43 bottoms are surrounded and locate, tentatively prop up each metal connecting sheet 4, again bonnet 3 is covered as shown in Figure 4 at last, make the needle plate of keeping somewhere in the upper shell 12 further prop up brace 4 and be close to good firm effect to obtain.In addition, can in upper shell 1, be provided with on registration holes 16 and the needle plate 2 in the said structure design and establish contraposition post 24, make both in conjunction with the time can guarantee that contraposition accurately is unexpected and fall partially.

As shown in Figure 5, the application examples that the utility model helps manufacturing, to replace to the Connection Block of different size from opening 11 when upper shell 1 of the present utility model, only will replace suitable inside needle plate 2 can simply finish, bottom 3 parts needn't be replaced fully all can be general, owing in assembling, have convenient practical characteristic of replacing, can obtain more motor-driven allotment on producing.

In sum, its effective design of novel structure of the present utility model, really make the relay Connection Block on making, more become motor-driven easy, can reduce cost significantly, remove this, needle plate also easily penetrates variable problem with the long distortion of formula in the moulding and produce, and the universal design of bottom also makes the molding expense greatly reduce because of being a small-sized separate component.
