The influence of processing accuracy on the performance of pogopin connector! The needle tube and needle of the pogopin connector are made of copper rods by turning and milling. The traditional processing method is to use a knife machine for processing. Although the cost of this processing method is low, the processing accuracy is very low, and it is suitable for applications in areas where the accuracy of pogopin products is not high.
Due to the continuous development of smart phones and smart wearable devices, current electronic products are gradually becoming lighter, thinner, and compact. In order to meet the needs of the market, the size of the pogopin connector is getting smaller and smaller, and the accuracy requirements for the pogopin are getting higher and higher.
The accuracy of pogopin products processed by different processing equipment will definitely be different. The influence of processing accuracy on the performance of pogopin products is manifested in the following two aspects.
First of all, the surface finish of high-precision pogopin products is very high. The surface finish of the outer wall of the needle tube will not have a great influence. The most affected is the inner wall. If the surface is rough, pogopin will rub when stretched elastically. The coefficient will be very large, which will cause lag. In addition, if the friction coefficient is too large during work, it will cause serious damage to the outer wall of the needle of the pogopin and the inner wall of the needle tube, thereby greatly reducing the service life of the pogopin.
Secondly, the size error of pogopin products. Products processed with low-precision equipment will definitely have large dimensional deviations, which will bring great troubles to later assembly and application, which will lead to cooperation. Unsatisfactory results.
