Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a high-precision miniature board-to-board connector socket. Background Technology

[0002] Board-to-board connectors are connectors that directly connect two or more circuit boards together, enabling signal transmission and power supply between different circuit boards. Typically, board-to-board connectors have the highest transmission capacity of all connector types and are mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, and military manufacturing industries. Existing board-to-board connectors usually consist of a longitudinally elongated insulating body and two rows of conductive terminals mounted on the insulating base. The insulating body has slots and two rows of terminal slots that penetrate the slots. The conductive terminals are inserted one by one into the corresponding terminal slots. The conductive terminals have elastic contact arms extending into the slots and solder feet extending out of the insulating body. Due to the close arrangement of the conductive terminals, the assembly operation is cumbersome, increasing production costs. The complex assembly process may require more manpower, time, and tools, leading to increased production costs and error rates. The complex operation steps may increase the probability of operational errors, resulting in more scrap and rework. Therefore, we propose a high-precision miniature board-to-board connection socket.
