Description

Technical Field

[0001] This utility model relates to the field of connector mating technology, specifically a board-to-board precision pitch connector with guide and stud locking. Background Technology

[0002] Board-to-board connectors are the most powerful type of connector, used to connect PCBs (Printed Circuit Boards). They play a crucial role in transmitting electrical signals, power, and data, and are primarily used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, and military manufacturing.

[0003] The existing Chinese utility model patent with publication number CN109638523 B relates to a board-to-board connector, comprising an insulating body extending longitudinally, terminals fixed to the insulating body, and protective brackets located at both ends of the insulating body in the longitudinal direction. The protective brackets are fixed to an end wall and have an end wall shielding plate covering the end wall and a side wall shielding plate at least partially covering the side wall. The side wall shielding plates are connected to the lateral ends of the end wall shielding plates. Each end wall shielding plate includes an end wall shielding portion covering the top surface of the end wall and an outer wall shielding portion bent from the side of the end wall shielding portion and covering the outer wall surface of the end wall. The outer wall shielding portion has elastic arms extending from its lateral ends along the inner wall surface of the side wall. The elastic arms of the protective bracket have a relatively long lever arm, which ensures stable assembly of the board-to-board connector while solving the problem of excessive elastic arm drop after insertion and removal of the board-to-board connector.

[0004] Existing conventional board-to-board connectors have pin pitches that cannot meet specific customer requirements. Furthermore, the lack of guide posts between the connector heads and sockets can lead to misalignment and incorrect insertion, making mating difficult. The absence of a locking mechanism between the printed circuit board and the connector also makes them unsuitable for harsh environments or devices with extremely high reliability requirements.

[0005] Therefore, those skilled in the art have provided a board-to-board precision pitch connector with guide and stud locking to solve the problems mentioned in the background art. Utility Model Content

The added guide structure enables better and more accurate positioning of the connector during connection, ensuring accurate mating of the plug and socket, preventing misalignment and misinsertion, improving the reliability and stability of the connector, and reducing problems such as poor contact caused by inaccurate mating. It also helps to improve installation efficiency. The stud locking structure between the printed circuit board and the connector increases the stability and durability of the entire connection system, making it suitable for use in harsh environments or equipment with extremely high requirements for connection reliability. In addition, in this device, a fixing structure is added to the upper end of the stud. The clamping plate is moved and installed into the fixed box by a spring, so that the hook is fixed to the back plate, thus fixing the stud. The above settings fix the stud by connecting the hook and the back plate, preventing the stud from falling off after long-term use. Attached Figure Description
