Abstract

The utility model relates to a contact plate, in particular to a contact plate of an arch appliance socket outlet which utilizes a forming die to be processed and leads the contact plate and an electric-conducting plate to be one body, and a plug jack is an arc shape; the contact plate comprises the electric-conducting plate and the contact plate; wherein, the plug jack composed by the contact plate is an arc shape, and the size of the plug jack is matched with the type model of the socket, the contact plate and the electric-conducting plate are integrated into one body by a connecting part; after the socket is formed, the other end of the contact plate is punctured into a flare opening, thus not only being beneficial to the plugging-in of the plug, but also greatly improving the rigidity of the plug jack.

Description

Arc appliance socket contact chip

Technical field

The utility model relates to a kind of contact chip, relates to especially that to utilize shaping mould processing, socket be arc, the arc appliance socket contact chip that contact chip and conducting strip are become one.

Background technology

In the appliance socket contact chip, contact chip and conducting strip generally all separate, and when socket plug service time is longer, form the distortion of contact chip and conducting strip easily separately, produce the bad situation of contact, also can produce electric spark when serious, cause potential safety hazard.

As the patent No. is 03823054.2 1 kinds of electric contact terminals, obtain by cutting and folding little conductive metal sheet, it comprises the rear portion and a front portion that can connect an electric wire, the front portion has one first pleated sheet, form a contact chip, has complementarity, contact chip comprises that at least one is positioned at the pressing part of the folding region of contact chip, this product has strengthened the elasticity of socket, relatively be fit to the use of two-phase socket, but in three phase mains, the locus of one of them plug can be restricted in manufacturing process.

And for example the patent No. is 200420048257.6 1 kinds of architecture advances to contact chip in the electric connector and switch plate, it all is made of one the formula structure with contact chip in all jacks and switch plate, there is not the contact resistance when making up between two, improved the electric property of electric connector, the whole punch forming of contact chip and switch plate, it is primarily aimed at the statement of the connector of the signal of telecommunication conducting between the different electronic installations, not to this statement of the appliance socket contact chip of utility model newly.

And for example the patent No. is the dichotomous contact chip of 200620065857.2 1 kinds of appliance sockets, this dichotomous contact chip comprises the sheet-insert body that connects lead, this sheet-insert body connects a plurality of little elastic contact chips, it is improved to single contact chip with the whole contact chip in the conventional socket and is divided into the form of a plurality of little elastic contact chips, again with it by the shaped design squarely that is usually used in appliance plug, the contact chip of shape such as rectangle and circle, it from local improvement the contact performance of contact chip, use also more on the domestic market, but its contact chip elastic force is always undesirable, along with the increase of access times and time, monolateral contact or the probability that does not reach because of distortion are bigger.

Summary of the invention

The purpose of this utility model is to be made up of a plurality of parts in order to solve contact chip and conducting strip, causes contact engaging and separating force poor, the contact-making surface instability, and provide a kind of contact engaging and separating force strong, and contact chip is stable, and processing technology is simple, at the bottom of the cost, appliance socket contact chip easy to assembly.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: arc appliance socket contact chip of the present utility model comprises conducting strip, contact chip, wherein the socket formed of contact chip is an arc, the socket size matches with the socket model, conducting strip and contact chip are formed one by the coupling part, in development size, conducting strip, contact chip and coupling part are one, after the socket moulding, contact chip strikes out horn mouth at the other end of coupling part, so not only be beneficial to the insertion of plug, and the rigidity of socket improves greatly.

As preferably, described bell-mouthed height is 1/5～1/3 of a contact chip height, it is main that what consider is the guide effect that plug rises when inserting, after bell-mouthed opening size is made arc by contact chip, the suitable angle of punching press gets final product, and as 5 degree or 10 degree, horn mouth does not have scar, the main area of contact chip short transverse is in order to contact with plug, to reduce resistance.

As preferably, a place is respectively established in the socket both sides that described coupling part is formed at each contact chip, and its intensity is more satisfactory like this, and the coupling part exceeds at least 2 sheet thicknesses in plane on the socket that conducting strip and contact chip form, in forming process, need certain bending size to guarantee.

As preferably, the height of described contact chip, the height of conducting strip and socket model match, the height of contact chip will match with the plug of socket, the height of conducting strip mainly is at this socket model, can be by much electric currents, so can making with the height of contact chip, conducting strip equates, or wideer or narrow than it.

As preferably, the arc socket that described contact chip is formed is provided with several, and its quantity and socket model match, as single-phase socket, porous socket etc.

As preferably, blanking of the present utility model, moulding all are disposable die stamping moulding, and material adopts dislocation to arrange, basic not waste, and its processing cost is lower.

Therefore, a kind of appliance socket contact chip of the utility model, existing contact engaging and separating force is strong, and contact-making surface is stable, have processing technology simple again, at the bottom of the cost, and has cancelled the advantage that contact chip and conducting strip in the original product need assembly technology.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is that the A of the utility model Fig. 1 is to view.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Referring to Fig. 1,2, present embodiment comprises conducting strip 1 and contact chip 2, the socket that contact chip 2 is formed is an arc, its size is pressed the socket model and is set, conducting strip 1 and contact chip 3 are formed one by coupling part 3, the coupling part is distributed in contact chip 2 both sides and respectively establishes one, in development size, conducting strip 1, contact chip 3 and coupling part 3 are same block of material, blanking, disposable die stamping moulding is adopted in moulding, when row sets material technology, material adopts dislocation to arrange, basically not waste, processing cost is also lower, behind the socket camber, the other end relative with the coupling part suppressed a horn mouth 21, the about 2mm of the height of horn mouth 21, the monolateral opening angle of horn mouth are 15 degree, thus, the rigidity of socket improves greatly, in the finished product assembling, do not worry because of conducting strip 1 yet, contact chip 2 is split type, need assemble and the dislocation deviation that produces.

The foregoing description is to explanation of the present invention, is not limitation of the invention, any structure after the simple transformation of the present invention is all belonged to protection scope of the present invention.
