Abstract

The utility model relates to a contact piece, in particular to a socket contact piece which is used for an electric appliance and can cause a contact piece and a conducting strip to be formed into integration by adopting forming die processing. The socket contact piece used for an electric appliance comprises the conducting strip and the contact piece, wherein the conducting strip and the contact piece are formed into integration by a connecting part, and the rigidity of a faucet is greatly enhanced after the faucet is punched and formed. The utility model has the advantages of large insertion force, stable contact surface, simple processing technique and low cost, and cancels assembly technology required by the contact piece and the conducting strip.

Description

The appliance socket contact chip

Technical field

The utility model relates to a kind of contact chip, especially relates to utilizing shaping mould to process the 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: appliance socket contact chip of the present utility model is made up of conducting strip and contact chip, the socket size that conducting strip and contact chip are formed is suitable with the socket model, the square size of the formed socket of conducting strip and contact chip respectively accounts for half of its width, 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, the rigidity of socket improves greatly, former conducting strip, the split type technology of assembling of contact chip has also been cancelled.

As preferably, described conducting strip length is suitable with the socket model, and according to the different model requirement, socket quantity has different requirements with conducting strip length.

As preferably, the socket size that the length of described contact chip is formed with conducting strip is suitable, and the length after the contact chip moulding generally at long three times of socket, had both guaranteed plug position, strengthened the elasticity of socket again.

As preferably, the height of described contact chip is identical with the height of conducting strip, and the socket that contact chip and conducting strip are formed is a cuboid, and the end of whole piece contact chip is a plane, the width of coupling part after the contact chip moulding length dimension 1/6.

As preferably, described coupling part exceeds at least 2 sheet thicknesses in plane on the socket that conducting strip and contact chip form, and in forming process, needs certain bending size to guarantee.

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 by conducting strip 1 and contact chip 2 and forming, conducting strip 1 configures by different socket models with the socket size that contact chip 2 is formed, conducting strip 1 and the square size of contact chip 2 formed sockets respectively account for half of its width, be symmetric figure, conducting strip 1 and contact chip 3 are formed one by coupling part 3, 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, after the socket moulding, 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.
