Technical Field
[0001] This utility model belongs to the technical field of PIN pin positioning devices, and in particular relates to a positioning device that prevents PIN pins on PCB boards from tilting. Background Technology
[0002] Pins are metallic materials in connectors used to conduct electrical (signal) electricity (transmission). They are key conductors in male and female connectors, affecting the transmission of current and information.
[0003] In the assembly of electronic devices, the mating of pins with connectors is a crucial step. However, pins are prone to misalignment or insertion difficulties on connectors, which not only significantly reduces production efficiency but may also lead to unstable equipment performance or even damage.
[0004] When the pins are tilted, they may collide or rub against other components of the connector, generating additional stress and wear, affecting its conductivity and mechanical stability. Furthermore, difficulty in insertion increases assembly time, and operators may damage the pins or connector due to excessive force, leading to product rework or even scrap. These issues not only increase production costs but may also affect product quality and reliability, ultimately impacting the user experience. Utility Model Content
