Description

Technical Field

[0001] This utility model relates to the technical field of WTB connectors, and in particular to a self-locking WTB connector. Background Technology

[0002] As a core component in electronic devices for signal transmission between cables and circuit boards, existing WTB connectors generally consist of two main structures: a socket and a plug. The socket is soldered to the circuit board via pins, and the plug connects to the cable. The two are fixedly connected by a locking structure. Currently, the mainstream locking methods are mainly divided into snap-fit ​​and threaded types. The snap-fit ​​structure relies on the engagement of the protrusion on the side wall of the plug with the recess in the slot of the socket to achieve fixation. The threaded structure uses the threaded sleeve on the outside of the plug to rotate and lock with the threaded interface of the socket. Both types of structures can meet basic electrical connection requirements and are widely used in various electronic engineering scenarios.

[0003] When in use, the snap-on structure requires the design of multiple sets of convex and concave mating parts, and the assembly requires strict precision. The threaded structure requires additional parts such as threaded sleeves and washers, which makes the overall disassembly process more cumbersome when the plug needs to be removed. Unlocking the threaded structure requires rotating it multiple times, which takes a long time. Unlocking the snap-on structure requires the use of tools to pry the protrusions, which can easily cause deformation of the parts. As a result, if it is reused in the future, its locking and fixing effect will be greatly reduced, affecting the stability of the plug when it is plugged into the socket.

[0004] To address this issue, we propose a self-locking WTB connector. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-locking WTB connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A self-locking WTB connector includes a socket and a plug. Contacts are provided on the inner wall of the socket and the side wall of the plug for electrical connection between a cable and a circuit board. The connector also includes: The device consists of an L-shaped limiting rod and a hemispherical limiting block. The limiting rod is located on the side wall of the plug. The vertical section of the limiting rod has a cavity, and a spring pin is connected to the inner wall of the cavity. The outer end of the spring pin extends to the outer side of the cavity. A slot is located on the side wall of the socket, and the limiting block is located in the slot. The spring pin and the limiting block are in a limiting fit. A double-sided inclined block is used to release the limiting relationship between the spring pin and the limiting block. A guide rod is connected to the side wall of the limiting block. The double-sided inclined block adopts a hollow structure and is sleeved on the outside of the guide rod. The limiting pin is used to fix the limiting rod to the side wall of the plug. The limiting pin is composed of two symmetrical fan-shaped blades fixedly connected. The side wall of the plug has a through slot on both sides. Limiting grooves are opened on the inner walls of both sides of the slot. The limiting grooves cooperate with the limiting pin to fix the position of the limiting rod.

[0007] Preferably, the side of the limiting block closest to the slot opening is an arc surface, and the side away from the opening is a flat sidewall. The side of the spring pin away from the plug is an inclined surface. The inclined surface and the arc surface cooperate to allow the spring pin to move to the other side of the limiting block.

[0008] Preferably, the planar sidewall of the limiting block is concave, and its size matches that of the double-sided inclined block.

[0009] Preferably, the sidewall surface of the guide rod is covered with a smooth layer to improve smoothness and enable the double-sided tilting block to move smoothly.

[0010] Preferably, the limiting rod passes through the slot and extends to the other side of the plug, and the inner wall surface of the slot is covered with a rubber pad to increase friction and ensure the stability of the limiting rod in the slot.

[0011] Preferably, a rotating groove is provided on the side wall of the limiting rod, the size of the rotating groove is matched with the size of the trajectory range formed by the rotation of the limiting pin, the limiting pin is rotatably connected to the inner wall of the rotating groove, and a knob is connected to the rotating end of the limiting pin.

[0012] Preferably, the limiting groove and the limiting pin are matched in specifications, and the groove formed after the limiting groove and the rotating groove are connected presents a complete circular structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention reduces the number of parts by using an L-shaped limiting rod, a hemispherical limiting block, and a spring pin in a self-locking structure, making the fit simpler. The additional double-sided inclined block and guide rod allow for easy disassembly by simply turning a knob, pushing the limiting rod, or pulling the limiting rod, eliminating the need for additional tools. This simplified operation reduces assembly and disassembly time. Furthermore, compared to existing snap-fit ​​connections, the adjacent sidewalls of the limiting block, spring pin, and double-sided inclined block are curved and inclined surfaces. Disassembly is performed using these surfaces, preventing damage to the locking structure. Therefore, it can be disassembled and reused multiple times without affecting the subsequent locking and securing effect. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-2A self-locking WTB connector includes a socket 1 and a plug 2. The socket 1 has multiple sets of pins connected to it, which are soldered to a circuit board. The plug 2 has a cable connected to it for signal transmission. During use, the plug 2 is inserted into the socket 1 to establish signal transmission. Contacts are designed on the inner wall of the socket 1 and the side wall of the plug 2. After the plug 2 is inserted into the socket 1, the contacts align, establishing an electrical connection between the cable and the circuit board, thus ensuring stable signal transmission. The connector also includes: Limiting rod 3 and limiting block 4 are provided. Limiting rod 3 is set on the side wall of plug 2. It is L-shaped and has a cavity in the vertical section. A spring pin 5 is connected to the inner wall of the cavity and the outer end of the spring pin 5 extends to the outside of the cavity. A slot is opened on the side wall of socket 1. Limiting block 4 is set in the slot. The outer end of the spring pin 5 extends into the slot and cooperates with limiting block 4. Limiting block 4 is hemispherical. The side near the slot opening is arc surface and the side of the spring pin 5 away from plug 2 is inclined surface. After pushing limiting rod 3 and spring pin 5 into the slot, the spring pin 5 can move to the other side of limiting block 4 by utilizing the cooperation of the arc surface of limiting block 4 and the inclined surface of spring pin 5. Then, the spring pin 5 pops out under the action of elasticity, so that the planes between spring pin 5 and limiting block 4 fit together, thereby forming a limiting relationship and fixing the relative position between plug 2 and socket 1. Reference Figure 3 A double-sided inclined block 6 is used to release the limiting relationship between the spring pin 5 and the limiting block 4. A guide rod 7 is connected to the side wall of the limiting block 4. The double-sided inclined block 6 adopts a hollow structure and is sleeved on the outside of the guide rod 7. The side wall of the guide rod 7 is covered with a smooth layer, which allows the double-sided inclined block 6 to move smoothly. The smooth layer is made of polytetrafluoroethylene. When it is necessary to disassemble the plug 2, push the limiting rod 3 inward into the slot. Utilizing the inclined surface cooperation between the spring pin 5 and the double-sided inclined block 6, the spring pin 5 can move smoothly to the other side of the double-sided inclined block 6. Then, pull the limiting rod 3 outward. At this time, the plane of the spring pin 5 and the double-sided inclined block 6 are aligned. When block 6 is in place, the spring pin 5 provides a certain force due to the lack of support for the double-sided inclined block 6 at this time, driving the double-sided inclined block 6 to move along the guide rod 7. The planar side wall of the limiting block 4 is designed to be concave, and its size matches that of the double-sided inclined block 6. As the double-sided inclined block 6 is driven into the concave surface, the gap between it and the limiting block 4 gradually narrows until the double-sided inclined block 6 is completely inside the concave surface and can no longer move. At this time, the spring pin 5 is lifted by the inclined surface of the double-sided inclined block 6, and then smoothly moves out of the slot from the upper side of the double-sided inclined block 6 and the limiting block 4, thereby releasing the fixed relationship between the socket 1 and the plug 2.

[0021] Reference Figure 4A limiting pin 8 is used to fix the position of the limiting rod 3. The limiting pin 8 is composed of two symmetrical fan-shaped blades fixedly connected. A rotating groove 81 is opened on the side wall of the limiting rod 3. The shape and size of the rotating groove 81 match the trajectory range formed by the limiting pin 8 during rotation, ensuring that the limiting pin 8 can rotate smoothly in the rotating groove 81. The limiting pin 8 is fixed to the inner wall of the rotating groove 81 by a rotating connection. A knob 82 is connected to the rotating end of the limiting pin 8. The knob 82 is cross-shaped and its outer wall is provided with anti-slip texture to increase friction and facilitate the user to turn it. The rotation of the limiting pin 8 can be controlled by rotating the knob 82. A through slot 9 is opened on the side wall of the plug 2. The limiting rod 3 passes through the slot 9 and extends to the other side of the side wall of the plug 2. Both sides of the inner wall of the slot 9 are provided with... There are limiting grooves 10 on both sides, which match the specifications of the limiting pins 8. After the limiting grooves 10 and the rotating grooves 81 are connected, the groove formed presents a complete circular structure. The circular structure coincides with the trajectory range formed by the limiting pins 8 during rotation, ensuring a tight fit between the limiting pins 8 and the limiting grooves 10. In use, by turning the knob 82, the limiting pins 8 can smoothly enter the limiting grooves 10. The two work together seamlessly to fix the limiting rod 3 in the slot 9, ensuring the stability of the connection between the plug 2 and the socket 1. When it is necessary to remove the plug 2, simply turn the knob 82 to rotate the limiting pins 8 out of the limiting grooves 10, which can easily release the position restriction of the limiting rod 3 in the slot 9. At this time, the limiting rod 3 can be pushed smoothly to complete the disassembly operation of the other end from the slot.

[0022] Reference Figure 5 The disassembly steps of the device are as follows: The spring pin 5 initially engages with the limiting block 4, restricting the limiting rod 3 within the slot, thereby achieving the connection and fixation of the socket 1 and the plug 2. When it is necessary to disassemble the two, the limiting rod 3 is pushed inward. Under the action of the inclined plane, the spring pin 5 can pass over the upper side of the double-sided inclined block 6 and move to the other side. Then, the limiting rod 3 is pulled outward. At this time, the plane of the spring pin 5 is in contact with the double-sided inclined block 6, which can provide a certain force to push the double-sided inclined block 6 to move along the guide rod 7. The double-sided inclined block 6 moves into the concave surface of the limiting block 4. When the double-sided inclined block 6 can no longer move, the spring pin 5 is lifted under the action of the inclined plane, and then moves out of the slot from the upper side of the double-sided inclined block 6 and the limiting block 4, releasing the limiting relationship between the spring pin 5 and the limiting block 4, so that the limiting rod 3 can be moved out of the slot, thereby completing the quick disassembly between the socket 1 and the plug 2.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
