Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a self-locking electronic connector. Background Technology

[0002] Self-locking electronic connectors belong to the field of electronic component connection technology and are mainly used to achieve reliable and stable electrical and mechanical connections between devices. These connectors are widely used in industrial equipment, consumer electronics, automotive electronics, and other scenarios requiring frequent plugging and unplugging or exposure to vibration. Their core requirements are ensuring signal transmission stability, ease of operation, and long-term reliability. With increasing device integration and more complex usage scenarios, traditional connectors are gradually revealing their shortcomings in positioning accuracy, vibration resistance, and ease of maintenance.

[0003] Existing connectors of this type generally suffer from the following structural defects: They lack a precise guiding mechanism during mating, making them prone to terminal misalignment or contact surface wear due to human error, leading to increased contact resistance over long-term use; locking mechanisms often employ threaded tightening or snap-on designs, which are prone to loosening and falling off under vibration, and unlocking requires two hands or tools, making it difficult to complete quickly in confined spaces; internal spring elements are often independently distributed, occupying significant installation space and experiencing elastic decay due to long-term pressure, resulting in decreased locking force; insufficient modular design necessitates replacement of the entire connector if a single component fails, leading to high maintenance costs; and traditional structures do not adequately consider fatigue life under high-frequency mating conditions, failing to meet the comprehensive requirements of modern equipment for connector miniaturization, intelligence, and high reliability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a self-locking electronic connector to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking electronic connector, comprising:

[0006] The connecting part and the limiting seat provided on the back of the connecting part are provided with wires and inserts respectively on the surface of the connecting part, and the limiting seat is provided with a plug hole and a guide hole on the front side.

[0007] A guide post is provided on the back of the connecting part, and a limiting groove is formed on the surface of the guide post;

[0008] The locking and releasing module is located within the cavity of the limiting seat and includes a push-button module, a limiting block, a fixing rod, a locking tongue, and a return spring. After the connecting part is fitted into the limiting seat, the insert is inserted into the insertion hole, and the guide post is inserted into the guide hole. Pressing the push-button module lowers the fixing rod and its connecting structure, tightly fitting the locking tongue into the limiting groove, thus connecting the connecting part to the limiting seat. On one hand, the plug-in connection and self-locking mechanism between the connecting part and the limiting seat eliminates the need for complex fixing steps, enabling rapid installation and significantly saving installation time and costs. On the other hand, the self-locking mechanism locks the connecting part onto the limiting seat after installation, effectively preventing loosening due to vibration or external force, improving connection stability and security. The unlocking button design allows for easy disassembly of the connecting part, facilitating subsequent maintenance and replacement. It is suitable for various electronic devices requiring rapid installation and reliable connection, and has broad application prospects.

[0009] Preferably, the shape and position of the insert of the connecting part correspond to the insertion hole of the limiting seat. When the connecting part is connected to the limiting seat, the insert is inserted into the interior of the insertion hole.

[0010] Preferably, the guide post and the guide hole correspond in shape and position, and the front of the limiting seat has a connecting hole. When the connecting part is connected to the limiting seat, the guide post is inserted into the interior of the guide hole, and the limiting seat can be connected through the connecting hole. The guide post and the guide hole are used to guide the connecting part to be accurately installed on the limiting seat.

[0011] Preferably, the return spring is sleeved on the surface of the fixed rod, and the limiting block is connected to the fixed rod, with the limiting block and the return spring in close contact. The return spring can be used for reset operations, while the limiting block also limits the movement of the return spring.

[0012] Preferably, the locking tongue is located at the end of the fixing rod, and the shape and position of the locking tongue correspond to those of the limiting groove. The fixing rod can drive the locking tongue to fit tightly against the limiting groove.

[0013] Preferably, the pressing module extends from the outer surface of the limiting seat, and the pressing module is cylindrical in shape. The pressing module is movably connected to the limiting seat, and its interior includes a rotor, a ratchet, and a pressing component that pushes the rotor. The self-locking mechanism can be controlled via the pressing module.

[0014] Compared with the prior art, the present invention provides a self-locking electronic connector, which has the following advantages:

[0015] This self-locking electronic connector, through the matching structure of the guide post and the guide hole, ensures that the connecting part is automatically and accurately positioned when it mates with the limit seat, avoiding poor contact or component wear caused by insertion deviation;

[0016] The limiting groove on the surface of the guide post forms a mechanical interlock with the locking tongue, maintaining a stable connection without external force intervention, effectively preventing accidental detachment caused by vibration or pulling, and significantly improving connection reliability;

[0017] The locking and releasing module adopts a linkage design between the push module and the return spring. The bolt can be triggered to retract and unlock with a single press. It is convenient to operate and ergonomic, especially suitable for confined spaces or one-handed operation scenarios.

[0018] The integrated layout of the limit block and the fixing rod optimizes the utilization of the internal space of the limit seat, reduces the overall volume while ensuring the integrity of the function, and facilitates the miniaturization design of the equipment.

[0019] Each moving part is automatically reset by a return spring, which avoids functional failure due to fatigue of elastic elements after long-term use and extends the service life of the connector.

[0020] The overall structure adopts a modular assembly method, and each component can be replaced and maintained independently, reducing the later maintenance cost, while ensuring the stability of the connector under high-frequency plugging and unplugging conditions. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution, a self-locking electronic connector, including: (See details) Figure 1 , Figure 2 , Figure 3 The connecting part 1 and the limiting seat 2 provided on the back of the connecting part 1 are provided with a wire 3 and a plug 5 respectively, and the limiting seat 2 is provided with a plug hole 8 and a guide hole 10 on the front.

[0029] A guide post 6 is provided on the back of the connecting part 1, and a limiting groove 7 is formed on the surface of the guide post 6;

[0030] Please see Figure 4 The locking and releasing module 15 is located inside the cavity of the limiting seat 2 and includes a pressing module 4, a limiting block 11, a fixing rod 12, a locking tongue 13, and a return spring 14. After the connecting part 1 is attached to the limiting seat 2, the insert 5 is inserted into the insertion hole 8. Pressing the pressing module 4 lowers the fixing rod 12 and its connecting structure, tightly fitting the locking tongue 13 against the limiting groove 7, thus connecting the connecting part 1 to the limiting seat 2. On one hand, the plug-in connection and self-locking mechanism between the connecting part 1 and the limiting seat 2 eliminates the need for complex fixing steps, enabling rapid installation and significantly saving installation time and costs. On the other hand, the self-locking mechanism locks the connecting part 1 onto the limiting seat 2 after installation, effectively preventing loosening due to vibration or external force, improving connection stability and security. The unlocking button design allows for easy disassembly of the connecting part 1, facilitating subsequent maintenance and replacement. This system is suitable for various electronic devices requiring rapid installation and reliable connection, and has broad application prospects.

[0031] Please see Figure 2 The shape and position of the insert 5 of the connecting part 1 correspond to the insertion hole 8 of the limiting seat 2. When the connecting part 1 is connected to the limiting seat 2, the insert 5 is inserted into the insertion hole 8. The shape and position of the guide post 6 correspond to the guide hole 10, and the limiting seat 2 has a connecting hole 9 on its front side. When the connecting part 1 is connected to the limiting seat 2, the guide post 6 is inserted into the guide hole 10, and the limiting seat 2 can be connected through the connecting hole 9. The guide post 6 and the guide hole 10 are used to guide the connecting part 1 to be accurately installed on the limiting seat 2.

[0032] Please see Figure 5 A return spring 14 is sleeved on the surface of the fixed rod 12, and a limiting block 11 is connected to the fixed rod 12, with the limiting block 11 and the return spring 14 in close contact. The return spring 14 can be used for a reset operation, while the limiting block 11 also limits the return spring 14. A locking tongue 13 is located at the end of the fixed rod 12, and the shape and position of the locking tongue 13 correspond to those of the limiting groove 7. The fixed rod 12 can drive the locking tongue 13 to fit tightly against the limiting groove 7. A pressing module 4 extends from the outer surface of the limiting seat 2, and the pressing module 4 is cylindrical in shape. The pressing module 4 is movably connected to the limiting seat 2. The pressing module 4 includes a rotor, a ratchet, and a pressing component that pushes the rotor. The self-locking mechanism can be controlled through the pressing module 4.

[0033] In this design, the main function of the push-button module 4 is to work in conjunction with the return spring 14 to achieve the extension and retraction of the bottom extension end (fixed rod 12) through elastic deformation. It employs a mechanical component widely used in push-button pens, whose structural principle includes a rotor, a ratchet, and a push-button component that drives the rotor. When the push-button component is pressed, the teeth between the push-button component and the rotor mesh, causing the rotor to rotate. Under the action of the spring force, the rotor slides along a specific structure, thereby achieving the pop-out or retraction of the extension end (such as the pen tip). This is a common component in existing push-button ballpoint pens or fountain pens, manufactured using known technology; its internal structure will not be described in detail here.

[0034] This solution involves attaching the connecting part 1 to the limiting seat 2, allowing the insert 5 to be inserted into the insertion hole 8, and the guide post 6 to be inserted into the guide hole 10. Under the action of the return spring 14, the guide post 6 drives the limiting protrusion 13 to be inserted into the limiting groove 7 of the guide post 6 for connection. The guide post 6 can be rotated on the connecting part 1 via the rotating handle 4, causing the guide post 6 to move the limiting protrusion 13 and the fixing rod 12 upwards, thus compressing the return spring 14. The return spring 14, on the telescopic rod 15, causes the connecting plate 11 to descend, and the connecting plate 11 to move the telescopic end of the telescopic rod 15 in the same direction. Simultaneously, the return spring 14 causes the connecting plate 11 and the fixing rod 12 to perform a reset operation.
