[0016] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.
[0017] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0018] See Figures 1-8 The diagram shown is a preferred embodiment of the present invention. The present invention relates to a quick-connect self-locking connector, particularly suitable for board-to-wire connections. In implementation, the present invention can be fixed on a circuit board to form a circuit connection, used for insertion into a male connector for connection to the wire end, realizing power or signal transmission. The quick-connect self-locking connector of the present invention has: an insulating base 1 and terminals 2. This embodiment exemplifies a two-terminal configuration, but is not limited to only two terminals.
[0019] The insulating base 1 is horizontal and has a socket 11. The terminal 2 is assembled on the insulating base and has a slot 21 that mates with the socket, so that the male terminal 31 of the male connector 3 can be inserted into the socket 11 and the slot 21 in sequence. The side wall of the slot 21 is provided with a contact part 22, a locking part 23 and an unlocking part 24. The contact part 22 makes contact and conduction with the male terminal 31, and the locking part 23 prevents the male terminal 31 from being removed, keeping the male terminal 31 in an inserted and conduction position and preventing it from easily coming loose. The unlocking part 24 is used to drive the locking part 23, so that the locking part 23 is released from the blocking state, allowing the male terminal 31 to be pulled out freely, which can realize self-locking and quick insertion after the connector is mated.
[0020] In this embodiment, terminal 2 is a U-shaped structure extending along the insertion direction of the male terminal. Slot 21 is a U-shape with both ends through, providing good structural strength. Contact portion 22 and locking portion 23 are respectively disposed on the left and right side walls of slot 21, and the contact portion 22 and locking portion 23 protrude and approach each other so that the contact portion 22 and locking portion 23 can clamp the male terminal 31 from the left and right sides. The contact portion 22 and locking portion 23 are integrally manufactured with the terminal, which can be stamped, making manufacturing convenient and providing good structural integrity. The contact portion 22 and locking portion 23 clamping the male terminal 31 not only achieves self-locking but also further increases contact conductivity, which is beneficial for power or signal transmission.
[0021] Furthermore, the locking part 23 is an elastic claw protruding into the slot 21 and inclined towards the insertion direction of the male terminal 31. The male terminal 31 has a ring platform 311 adapted to engage with the locking part 23, increasing the engagement force. In this embodiment, the insertion end of the male terminal 31 is tapered for easy insertion, and the locking part 23 is an elastic claw inclined towards the insertion direction of the male terminal 31. When the male terminal 31 is inserted, the locking part 23 can be automatically pushed open to achieve quick insertion. After the male terminal 31 is inserted into place, the locking part 23 uses elasticity to engage with the ring platform 311, forming a support, thereby achieving self-locking, preventing the male terminal 31 from exiting, and keeping the male terminal 31 in an inserted and conductive posture. In this embodiment, in order to satisfy the insertion and removal and contact conductivity of the male terminal 31, the contact part 22 is designed in the shape of an arched bridge. The two ends of the contact part 22 are connected to the corresponding side walls of the slot 21, which has good structural integrity, satisfies elastic contact, and also has better fatigue resistance, improving service life. The unlocking part 24 is a protrusion extending from the locking part 23. It is an integral structure that is easy to manufacture. In this embodiment, the unlocking part 24 is located on the upper side of the locking part 23 and close to the end of the locking part. A portion of the unlocking part 24 extends from the pre-set clearance hole 12 of the insulating base 1 so that the unlocking part 24 can be manually operated to pry open the locking part 23, thereby releasing the locking part 23 from the blocking state and allowing the male terminal 31 to be pulled out freely.
[0022] In this embodiment, the terminal 2 is embedded in a pre-set receiving groove 13 in the insulating base 1. The receiving groove 13 communicates with the socket 11. The shape and size of the receiving groove 13 match the terminal 2, facilitating accurate insertion and assembly, and improving structural stability. The terminal 2 is provided with a buckle 26, which engages with a pre-set mounting bracket 16 inside the receiving groove, ensuring a stable connection between the terminal and the insulating base, preventing loosening and improving insertion and removal performance. The terminal 2 has two welding feet 25 extending from the insulating base 1, respectively located at both ends of the terminal 2. The welding feet 25 are used for soldering onto the circuit board to form a conductive circuit. Both ends of the terminal 2 are also soldered for fixation, increasing stability and conductivity.
[0023] To further facilitate manufacturing and assembly, the insulating base 1 in this embodiment is designed to be formed by combining an upper shell 14 and a bottom cover 15. A receiving groove 13 is disposed in the upper shell 14 with its opening facing downwards. The terminal 2 is embedded in the receiving groove from bottom to top. The bottom cover 15 covers the upper shell 14 and supports the U-shaped bottom surface of the terminal 2. The bottom cover 15 is provided with an upwardly protruding hook 151. The hook is inserted into the upper shell 14 to form a hook connection, which facilitates the combination of snap fasteners. In order to further meet the needs of disassembly and maintenance, corresponding process holes are opened on the upper shell 14 so that the hook 151 can be unhooked with tools, thereby separating the upper shell 14 and the bottom cover 15.
[0024] In this embodiment, the upper side of the bottom cover 15 has an upwardly protruding rib 152, which corresponds to the U-shaped bottom surface of the support terminal 2, increasing support and stabilizing the terminal 2 in the insulating seat. The buckle 26 is provided on the ends of the left and right side walls of the slot, and an expandable and retractable elastic hole 27 is opened on the side wall of the slot. The elastic hole 27 is close to the buckle 26, so that the buckle 26 has expansion and retraction elasticity, which facilitates disassembly and maintenance.
[0025] The bottom cover 15 of this embodiment has a downwardly protruding anti-foolproof positioning post 153 on its lower side, which is used for assembling the upper plate. There are two anti-foolproof positioning posts 153, which are integrally manufactured with the bottom cover 15. The two anti-foolproof positioning posts 153 have different outer diameters, which have the function of preventing fooling and facilitate accurate assembly.
[0026] This utility model's terminal has a slot that mates with the socket on the insulating base, allowing the male terminal of the male connector to be inserted into the socket and slot sequentially. The side wall of the slot is provided with a contact part, a locking part, and an unlocking part. The contact part makes contact with the male terminal for conductive connection, while the locking part prevents the male terminal from retracting, maintaining its inserted conductive position. The unlocking part drives the locking part, releasing it from its blocking state and allowing the male terminal to be freely pulled out. This structure ensures conductive connection when the male terminal is inserted and utilizes the locking part for self-locking, preventing the male terminal from falling out on its own, improving connection stability and durability, and preventing accidental pull-out. It is suitable for various applications, especially industrial production and medical equipment. When the male terminal is pulled out, the unlocking part releases the locking part, allowing the male terminal to be freely pulled out. The structure is simple, assembly is convenient, and it can achieve self-locking and quick-connection after connector mating, offering excellent practicality.
