Description

Technical Field

[0001] The utility model is applied to the field of connectors, and particularly relates to a Pogo pin needle-membrane balancing structure. Background Art

[0002] Connectors, as core components of consumer electronics modules, play an indispensable role in the smooth transmission of signals within electronic products, and their market demand remains strong. As electronic product designs trend toward thinner, lighter, and more sophisticated designs, internal circuit layouts have become increasingly complex and detailed, leading to a significant increase in the use of connectors and their accompanying cables. To address the challenges posed by this trend, particularly the significantly increased precision required for connector pin testing, Pogo pin membrane technology has emerged. Currently, common Pogo pin membrane designs typically integrate an adapter PCB behind the tail pin block, which primarily handles signal transfer. However, this design also presents a problem: when the adapter PCB is connected to the tester via a cable or wiring harness, these connecting wires may generate pulling force during the dynamic movement of the Pogo pin, causing the floating block at the pin membrane head to tilt. This tilting phenomenon can hinder the smooth insertion of the connector, ultimately leading to connection test failure. Based on the above problems, if a special pogo pin connection structure can be designed, which uses a soft flat cable pair to balance the two sides of the pogo pin needle membrane, and at the same time transfers the signal to a PCB board, the soft flat cable harness can pull the transfer PCB, but will not affect the overall balance of the pogo pin; thereby achieving the pogo pin needle membrane to balance the connector during movement and thus achieve precise connection. The connection structure guides the connector in through the floating block at the head of the pogo pin needle membrane; then compresses the head of the floating needle block to make the probe head leak out and contact the connector pin until it stops after reaching the limit surface. The structure is simple, the movement is smooth, and the control is convenient. It is very convenient to achieve precise signal connection and can well solve the above problems.
