Description

Turntable POGOPIN power and electricity tester

Technical Field

The invention relates to a tester, in particular to a turntable POGOPIN force and electricity tester.

Background

POGOPIN CONNECTORs, i.e., POGOPIN CONNECTORs, also called header CONNECTORs, pogo pin CONNECTORs, probe CONNECTORs, etc. The spring type probe is mainly formed by riveting and prepressing three basic components of a sliding needle, a spring and a needle tube through a precision instrument, and a precise spring structure is arranged in the spring type probe. In the use, the product passes through the thrust of spring and is ejecting with the sliding needle to guarantee the switching on of electrical layer face.

In the past, the application field of POGOPIN mainly focuses on the conduction level, such as power supply to the corresponding components, transmission of switching value signals, and the like. Nowadays, as more and more product designs are developed toward miniaturization and refinement, more and more POGOPIN connectors are used to transmit high frequency signals and partially replace conventional coaxial connectors.

Experiments prove that among numerous parameter indexes of POGOPIN, the elasticity and the impedance of the spring are the most important performance indexes and have direct correlation, and the excessive elasticity or the insufficient elasticity can cause the impedance to exceed the standard. If the impedance is too large, communication abnormality of high-frequency signals can be caused, even signals are lost, and finally the performance of the connector cannot reach the standard. Therefore, the elasticity and resistance test of the finished POGOPIN product is a very important part.

The existing equipment module for testing the elasticity and the impedance of a POGOPIN finished product can only meet the testing requirement of a product with a larger size, and the miniature POGOPIN product with the total length of less than 8mm and the diameter of less than 3mm cannot be well loaded and tested. And the quantity of products which can be tested by the equipment at one time is relatively small, and the requirement of the beat cannot be met in the face of the shipment quantity of miniature POGOPIN products which are hundreds of thousands of goods per week. Most importantly, the existing equipment for testing the POGOPIN product generally adopts two testing processes to respectively test the elasticity and the resistance of the POGOPIN product, and the total processes are more in the testing process, so that the testing efficiency of the equipment is lower, and the testing requirement is difficult to meet. In addition, the sealing performance and the data exporting function of the resistance tester in the device are lacked, and the requirement of a customer on the acquisition and storage of product test data cannot be met.
