Auto Key Spring Metal Stamping Part Good Elasticity

Auto key spring metal stamping part

With the development of automobile technology, car remote key is more and more widely used in the car, its remote key

There are more and more kinds of functions and shapes. The different shapes of the keys also put forward higher requirements for the shrapnel structure on the PCB board used to contact the battery to realize circuit conduction. At present, the disclosed car key projetiles structure has the following problems: low tensile カ, bands are easy to fatigue deformation, which makes the rebound effect poor, affecting the use effect of shrapnel; The poor elasticity of the spring, small contact pressure カ and large contact resistance lead to oxidation of the contact points between protiles and batteries, and the service life is greatly reduced. In order to solve the problem of contact resistance, the existing technology adopts the method of increasing current flow, but this method is not practical. The battery is generally 3V button battery, and the replacement of high current battery requires the replacement of electronic components, which directly leads to the increase of cost.

The technical problem to be solved by the utility model is to provide a car key shrapnel structure with good elasticity and high tensile カ, so as to achieve good contact with the battery contact point and not easy to produce oxidation. In order to solve the above technical problems, the projetiles piece structure of the utility model comprises a projetiles piece body between a battery and a PCB board. The projetiles piece body comprises a vertical plate and a horizontal plate between the same end of two vertical plates. At the other end of the vertical plate is provided with a welding foot for welding on the PCB board. A first warping plate and a second warping plate are arranged between the vertical plates on opposite sides of the horizontal plate. The warping direction of the first warping plate is opposite to that of the second warping plate. The ends of the first and second warping plates are provided with sharp convex. The projetiles body surface is provided with a layer of nickel through electroplating. The utility model adopts the structure of projetiles, which has good projetiles structure and can enhance the contact pressure between the shrapel and the battery. Good projetiles make the contact point between the projetiles and the battery better, so that the contact resistance becomes smaller.

Advantages of Acid bright tin plating:

1. Tin is reduced by bivalent, saving electricity consumption;

2. Plating bath has high conductivity, low bath current and high current efficiency;

3. The operating temperature is close to room temperature, without heating equipment;

4. Gloss coating can be obtained by using appropriate additives;

5. Less damaging to the substrate.
