Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a novel double-row male connector. Background Technology

[0002] In the field of circuit board connections for electronic devices, connectors are key components that enable electrical connections between circuit boards and external components or other circuit boards. Traditional double-row male connectors are widely used in various electronic devices, such as computers, communication equipment, and consumer electronics, to meet the needs of multi-line connections.

[0003] The shortcomings of existing technology:

[0004] 1. Connection stability: The terminal block fixing structure of traditional double-row male connectors may have defects, which may cause the conductive terminals to shift or loosen during long-term use, especially under conditions of frequent plugging and unplugging, vibration, or external interference, affecting the stability of the electrical connection and potentially leading to equipment failure or signal transmission interruption.

[0005] 2. Installation and Fixing: When traditional double-row male connectors are installed on circuit boards, the fixing structure of their insulators may not be secure enough, making them prone to loosening or warping during installation or use. This not only disrupts the overall layout of the circuit board but may also lead to electrical connection failure between the connector and the circuit board. Furthermore, the installation process can be complex, requiring additional fixing accessories and cumbersome procedures, increasing production costs and assembly time.

[0006] 3. Regarding the anti-mis-mating function: In practical applications, due to the similarities between connectors of different specifications and models, traditional double-row male connectors lack an effective anti-mis-mating marking structure, which can easily lead to mis-mating with female connectors or other incompatible connectors during the mating process. This may damage the connector itself and the connected circuit board, resulting in increased equipment maintenance costs and reduced production efficiency.

[0007] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0017] Furthermore, the conductive terminal is L-shaped overall, with a bending angle of 90°±5° between the fixing part and the welding part. The welding part is bent towards the mounting part of the insulator, and a stress-relieving rounded corner is provided at the bend. The welding part is used to weld onto the circuit board.

[0018] Furthermore, the end face of the insulator's insertion portion away from the mounting portion is provided with an anti-misinsertion marking groove.

[0019] Furthermore, the side of the mounting hole facing away from the mating groove is provided with a guide chamfer;

[0020] The guide chamfer is a 45° bevel or a rounded transition surface.

[0021] Furthermore, the mounting portion of the insulator includes three mounting bases;
