Abstract

The utility model relates to a pin of an electric plug. The unfolded piece body of the novel pin of the utility model is a long rectangle with one end forming three end feet which have proper length and can be cut and separate and with the other end provided with a notch at the center part, and both sides are provided with two end feet. At the beginning, the unfolded piece is folded and attached together causing two side end feet in the three end feet to be bended outward and the end foot at the center part to be bended and extend into the notch between two end feet at the other end, and the three staggered end feet are used for clamping a wire. The utility model saves material, and keeps the functions of the existing pin to clamp the wire and to be mutually connected and fixed with the plug.

Description

The pin of plug

The utility model is a kind of pin of plug, and You Zhike reduces waste material, reduces production costs and assembles firm pin.

In the cost of plug, the pin lamellar body of metal material accounts for significant proportion, i.e. in the slice shape design, if can more lack by waste material when punching out, and then its cost is lower; Commonly using aspect the product, the expansion shape of pin lamellar body, non-is rectangular-shaped, and be " I " word shape just like, all designs of position are protruded at the two ends up and down of right its " I " word shape, make that waste material remnants are a lot of, and it is shown in the 5th figure, when desiring the expansion lamellar body A of a plurality of pins of punching out arranged side by side on stock, this two pin launches to enclose between the lamellar body A area and is waste material B partly, and generally speaking, the waste material B that the product of commonly using form accounts for the gross area sizable ratio, form waste, improve manufacturing cost relatively.

Again, the pin configuration of general existing plug is how made above-mentioned " I " word shape, it mainly is to make pin C form three parts, shown in the 6th figure, be pin body C1, thread tension disc C2 and support chip C3, wherein thread tension disc C2 is in order to direct clamping electric wire, and support chip C3 is used to provide to pin body C1 and plug to be mutually the required cross-brace structure of vertical card fixed bit; So, launch lamellar body A side and be set as " I " word shape, to make its upper and lower protrusion position form or fixing required extension centre line sheet C2 of pin and support chip C3 are provided in order to the clamping electric wire; Yet this design is always attended to one thing and lose sight of another, can't take into account material-saving (as above-mentioned) and function (establishing) with the plug group both, be still must take as the leading factor at last, and make it be difficult to adopt the low-cost suitable pin made from function.

In addition, at present being seen above-mentioned pin C design, it generally is to apply to flat and thin plug D (as joining the 7th figure), mainly makes its pin C stand in plug D flat wide, this also makes the support chip C3 of pin C be embedded in the plug D body; Precisely because the form of " I " word shape makes support chip stretch out, and generally speaking, can't fit on the leptoprosopy of being located at long rectangular insert, cooperates it and need give the suitable person of moulding in addition, lack versatility.

The utility model purpose is promptly providing a kind of pin of plug, and purport is the disappearance of the existing plug of improvement, and the design that utilizes rectangle to launch lamellar body replaces used " I " word shape and launches lamellar body, makes to reach material-saving, also possesses each cage structure of existing usefulness and function simultaneously.

The utility model purpose is to realize like this, the long rectangle that constitutes pin launches lamellar body and forms the three suitable long end pin of separation that cut off in the one end, end then forms notch in central authorities in addition, tool end pin is established in both sides, use long rectangle expansion lamellar body and be able to the punching out arranged side by side of little spacing to save stock, and launching lamellar body fits to Zhe, fitting makes its two sides pin of three end pin to bending, can be the mated plug positioning supports, its central authorities' end pin bendable is stretched in the notch of holding in addition between two end pin, and the beginning utilizes these three staggered end pin just can give the clamping electric wire.

The utility model has kept existing pin centre to hold electric wire, and the function that engages one another and set firmly with plug, has saved material, has reduced cost.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a punching out expanded view of the present utility model;

Fig. 2 is the structural representation of the utility model planar shaping;

Fig. 3 is the structural representation of the utility model stereo shaping;

Fig. 4 is the enforcement illustration of the utility model mated plug;

Fig. 5 is the expanded view of existing pin punching out;

Fig. 6 is the structural representation of existing stereo shaping;

Fig. 7 is the enforcement illustration of existing mated plug.

Please refer to shown in Figure 1, be the expanded view of the utility model during with the punching out of stock one volume, at first with regard to this creation launches lamellar body 1, its be set as one long rectangular-shaped, because profile is all flat side, and does not have the restriction of protuberance, can reduce to minimum so respectively launch the arrangement pitches of lamellar body 1 on stock, itself and aforementioned existing pin are compared, and see that promptly making the residue waste material that launches behind the lamellar body 1 can reduce to minimum; In addition, the utility model launches the shaped design of lamellar body 1, as shown in Figure 2, is to make the one end form the three suitable long end pin 11,12,13 of separation that cut off, and end then forms notch 14 in central authorities in addition, and tool end pin 15,16 is established in both sides.

Continuous with reference to shown in Figure 3, when desiring to be processed into pin with above-mentioned expansion lamellar body 1, be that order launches 1 couple of Zhe of lamellar body, and its two sides pin 11,13 of three end pin 11,12,13 is outwards laterally bent, and central authorities' end pin 12 curved stretching in the notch 14 of holding 15,16 of two ends in addition, and order two end pin 15,16 herein slightly give curved two end pin, 11,13 curved end in addition of closing in horizontal bending; Constituting by this, as shown in Figure 4, when with the moulding of the utility model pin mated plug, is directly to utilize three staggered end pin 12,15,16 clamping electric wire 2 in opposite directions, and the also suitable lamellar body that can limit Zhe of the form of this clamping electric wire 2 opens; After the pin mated plug 3 of clamping electric wire 2 is molded and shaped, this outwards laterally two end pin 11,13 of bending more can be a support positioning architecture, the beginning makes pin be consolidated on the plug 3; And, can cooperate general flat thin type plug or long rectangular insert to use under end pin 11, the 13 form certain specifications design of this two supports location, applicability is extensive.

Again, above-mentioned central authorities are notch 14, and the sheet end of both sides tool end pin 15,16 is the relative inner edge punching out grinding tooth 17 (ginseng Fig. 3) that can make its two ends pin 15,16, suitable make that denticle is protruding to be prolonged on 15,16 on end pin, and using more can the clamping electric wire, unexpected coming off; In addition, also can take up an official post and establish raised line 18, with reaching the effect that increases the clamping electric wire in the relative inner face of three staggered end pin 12,15,16.

Moreover 1 couple of Zhe of expansion lamellar body of the present utility model fits and can be to become in addition the curved hollow cylindrical that coats of arc, thinks a round pin, and forms above-mentioned function with giving the bending end pin that utilizes the end.
