Description

Terminal for series connecting wire in line

The utility model relates to the conducting terminal in a kind of connector, particularly a kind of wire rod terminal that is connected in series side by side.This terminal is formed a kind of having in a plurality of tenon seats side by side of bar chain that is become by the sheet material punching out by the terminal bar clip that the punching out of circle wire rod becomes.

Generally be used for the splicing ear in computor-keyboard or the Genius mouse joint, because of its quality directly influences the execution of output signal, so how to make high-quality and to take into account the terminal of cost requirement very important.The production method of terminal has two kinds approximately at present: the one, make with car system mode, and the one, be rolled into terminal by direct the dashing of sheet material.Repeat after the detailed structure of these two kinds of production methods and the good and bad appearance thereof, but generally speaking, it is too high bad with quality that its major defect is respectively cost, the two can't overcome simultaneously.

Fundamental purpose of the present utility model promptly is to provide a kind of wire rod terminal that is connected in series side by side, and it can reduce cost effectively.

A purpose more of the present utility model is to provide a kind of wire rod terminal that is connected in series side by side, and its quality is more good, thereby can promote result of use.

Another purpose of the present utility model is to provide a kind of wire rod terminal that is connected in series side by side, and this terminal is fit to carry out automated production.

Be further to understand formation of the present utility model, the accompanying drawing of special attached necessity and be described in more detail in after.

Fig. 5 is the stereographic map of single-piece of the present utility model;

Fig. 6 is a floor map of the present utility model;

Fig. 7 is that terminal of the present utility model is set in the sectional view in the set collar;

Fig. 8 is use embodiment of the present utility model.

The joint 1 that generally is used for computor-keyboard, Genius mouse as shown in Figure 1, but socket one set collar 2 in its front end, and the terminal 3 that the utility model refers to can be hubbed within the set collar 2.How the specification of this terminal 3 internationalizes, can not arbitrarily change.For example terminal 3 be used to the to peg graft minimum diameter of front end of usefulness is 0.6mm, promptly is a kind of standardized size, at this, also with this specification as data relatively are discussed in this case.Again because the front end of terminal 3 must peg graft with relative joint in the computer, the rear end then must and wire bonds, thereby terminal 3 needs just can become general joint finished product again through one electroplating process in making the back usually; And can infer, be quite very difficult at the 0.6MM line footpath tail end lead of burn-oning, have the tail end that is easier to weld and also can significantly increase work efficiency if terminal 3 can be made certainly.

Fig. 2 is a kind of common terminal 3A with the indivedual shapings of car system mode.In order it effectively to be embedded in the set collar 2 (as shown in Figure 3), must make the oblique ring 3A1 with a ring maximum gauge, its reference diameter is 1.25mm.The terminal 3A that makes in this way and its shortcoming of terminal comparison of the present utility model are:

One. cost is too high:

1. owing to form for loosing singly to make, so can only select the gold-plated mode favourable to inserted terminal when considering to electroplate, just whole Zhi Duanzi 3A is the plated with gold layer, can carry out the gold-plated electroplating cost of selectivity compared with the utility model, exceed quite a lot of;

2. car system mode must have the car bits loss of material, has improved cost virtually.

Two. effect is bad:

1. the car goods must form the car line, leave bigger space in the grafting contact interface, so contact resistance is bigger;

2. as shown in Figure 3, the insulation distance d near excessively (comparing) between the maximum tiltedly ring 3A1 of two terminals of adjacent 3A with the utility model, thereby the situation of electromagnetic interference (EMI) (sudden change ripple, clutter, conducted signal output weaken or the like) is comparatively serious;

3. accuracy tolerance is controlled to be ± 0.03mm.

Three. because it is indivedual systems of loosing, so production run can't reach the robotization requirement of batch process.

Another kind of commonly use terminal 3B, ask for an interview shown in Figure 4 by what the sheet material punching out became.Can find out that terminal 3B is connected with the rear end lath and punching out becomes singly side by side, and terminal 3B itself also be that a kind of hollow is dashed the structure 3B1 that rolls up, can partly improve the shortcoming of above-mentioned terminal 3A, but the mode of itself making still has following shortcoming:

One. the life-span is short:

1. because of its preceding inserted terminal also is a hollow structure, intensity is very poor, if butt joint inaccurate or overexert, askew connecing, often have the situation that wrecks and occur, therefore this terminal finished product all is reluctant to adopt by many manufacturers;

2. because of inserted terminal is that punching out is rolled into circle, its circularity is not good, so friction is big when pegging graft, the life-span shortens.

Two. effect is bad:

1. not good because of circularity, can be attended by the contact shortcoming that effect is bad, resistance value is bigger;

2. accuracy tolerance control also is ± 0.03mm.

Terminal of the present utility model constitutes asks foreknowledge shown in Figure 5.Terminal bar 3 is directly formed by the round wire rod punching out of line footpath 0.06mm, except that keep leading portion inserted terminal 31 lines footpath constant, the rear end then in passing punching out become U-shaped shape tail end 32, utilize this U-shaped groove can supply lead conveniently take attached welding.Certainly, if make semicircle, V-arrangement tail end, also can be used in the utility model with equal effect groove.There is simultaneously of becoming to have the adjacent tenon seat in many intervals 4 in addition by the light sheet punching out, this tenon seat has the side plate 41 a plurality of facing each other that has washed off with the sheet material both sides, and clamping slot 42 is arranged in this side plate upper punch, utilize the clamping slot 42 of two correspondences can a terminal bar 3 is fixing within it.Fig. 6 is a floor map of the present utility model, tenon seat 4 of the present utility model as can be seen from Figure is button center sections built in terminal bar 3, significantly terminal bar 3 is divided into regularly two sections of front and back, make the utility model when implementing plating, can adopt selectivity gold-plated, just gold-plated on the inserted terminal 31, zinc-plated on tail end 32, this is because inserted terminal 31 will be pegged graft with other joint, should adopt the high gold plate of electrical efficiency, and tail end 32 must and lead connect with soldering, so have a preferable welding effect in that tail end 32 is zinc-plated.

Fig. 7 is that terminal bar 3 of the present utility model is hubbed on the sectional view in the set collar 2.A kind of design of tail end 32 is provided among this figure in addition, is the flat pattern that its punching out is become to have circular hole 321, and the characteristics of easy welding electric wire can be arranged equally.In addition, terminal bar 3 of the present utility model becomes with the direct punching out of wire rod, the hypotenuse 33 that its posterior segment is made have a maximum gauge, its reference dimension only is 0.8mm, decide the retaining agency part as the embedding that terminal bar 3 is inserted in the set collar 2, minimum insulation between terminal bar 3A more shown in Figure 3 keeps fartherly apart from d, and interference of electromagnetic field situation is difficult to be taken place.

Formation of the present utility model is also uncomplicated, but the advantage that this kind structure is produced is quite a lot of, and division is as follows:

One. reduce cost:

1. because electing property of the utility model is gold-plated, and have a greater part of area to electroplate the lower tin of price, thus electroplating cost can reduce near half;

2. round wire rod, the board cost of making terminal bar 3, tenon seat 4 are quite cheap.

Two. the life-span is long, effect is good:

1. because of the circle wire rod generally is to make to take out the system mode, circularity is good, intensity good, and surface in contact is level and smooth, and it is little to rub, and resistance is lower;

At present the wire rod manufacturing technology make its tolerance can be controlled in ± 0.01mm in;

3. as shown in Figure 7, can comparatively not commonly use the person because of the minimum insulation of 3 on the terminal bar in the set collar 2 apart from d and keep fartherly, thereby insulativity is preferable.

Three. because its planform is the chain band shape of rule, the no matter manufacturing of its terminal bar 3 or be inserted in steps such as set collar 2 welds all is fit to be designed on the production line flow process of automatic batch production.

Fig. 8 illustrates the embodiment that the utility model is applied to the computor-keyboard joint.
