The rise of smart wearable, cell phones do more and more thin and light, fast charging prompted by the increase in demand for high-current connectors, making the antenna thimble connector (POGO PIN spring needle connector) is more frequently used, now on the market for smart digital products basically use to the antenna thimble connector, only part of the low-end products may still be used shrapnel type connector; Next, please follow the Dongguan connector PIN pin Manufacturers group birch precision together to understand the antenna thimble connector in the selection and application to the product, should pay attention to what matters?

1. Antenna thimble connector working stroke selection

Selection of antenna thimble connector must be based on the space of the product used, select the range of working stroke; space is too small will be on the antenna thimble connector spring over-compression, affecting the life of the space is too large, may cause the contact is not in place, there is an unstable impedance, instantaneous breakage of the phenomenon.

2. Selection of plating materials

Plating material in the antenna thimble connector has to increase the conductivity, prevent oxidation, anti-wear and other roles, different materials, its role is not the same, like gold has good electrical conductivity, for high-current connectors, high impedance requirements of the product will generally choose to electroplated gold.

3. plating film thickness has those effects

Antenna thimble connector in the work of the antenna must be contacted due to a certain amount of friction will produce a long time there will be wear and tear, the thickness of the plating film will have a great impact on the service life of the product, when used to a certain limit of the plating layer is worn off, there may be excessive resistance, impedance and other phenomena such as instability. 100,000 times of the antenna thimble plating layer is thicker than 10,000 times of the surely some, so in the selection of the product, please be sure to So when selecting the product, please make sure to choose the plating requirement according to the demand.

4. The effect of elasticity

The contact force of the antenna thimble connector originates from the internal spring, the size of the spring elasticity can directly affect the antenna thimble impedance size, stability; elasticity is too large, it will increase the coefficient of friction, which has an impact on the service life of the antenna thimble.

Through the above 4 elements simply on the antenna thimble in different products, different use of the environment to choose the corresponding products, as well as price and other factors.

For antenna thimble connector demand for such a large number of a product, there must be a lot of manufacturers, the domestic antenna thimble environment competition is also very fierce; there is a low price to get customers, this kind of spring customized manufacturers produce most of the products poor quality and low price, generally used in the requirements of the product is not high; there are also quality to win, the price is high, generally used in the requirements of a very high level of products, the output will be Restricted; there is a class that is, price and quality are in the middle, not like the quality-oriented factories as high as the price is high, of course, product quality is also higher than the price to win a lot, can be described as cost-effective.
