Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a button-type locking connector. Background Technology

[0002] Traditional connectors generally use direct plug-in or threaded locking methods. The former has the risk of loosening, while the latter is cumbersome and time-consuming. Although existing button-locking connectors improve convenience, most of them have the following problems: the buttons are relatively small, and the locking and unlocking status is not obvious, sometimes requiring repeated pressing for confirmation; the number of configurable pins is limited; operation is laborious, requiring considerable pressing force; there is insufficient protection against accidental touches, and the exposed buttons are prone to accidental activation. In addition, accidental unlocking may still occur in vibration environments, affecting the reliability of the connector and making it difficult to meet the needs of industrial scenarios for efficient, stable, and long-life connections. Utility Model Content

[0003] The main purpose of this invention is to provide a button-type locking connector, which aims to improve the reliability of the connector and the user experience.

[0004] To achieve the above objectives, this utility model proposes a button-type locking connector, comprising:

[0005] A socket assembly, wherein the socket assembly has a first connecting portion protruding;

[0006] A plug assembly includes a housing with an internal mounting cavity. A fixing plate and a second connecting portion are disposed adjacent to each other within the mounting cavity. An elastic element is connected to the wall of the mounting cavity of the second connecting portion. The elastic element can push the second connecting portion to form a mating gap with the fixing plate. The first connecting portion can be inserted into the mating gap. A control element is connected to the side of the second connecting portion away from the fixing plate. The control element extends partially outside the housing. Moving the control element can press / release the second connecting portion to lock / release the first connecting portion.

[0007] In one possible implementation, a plurality of guide posts are provided around the second connecting portion within the mounting cavity, and a connecting ring is provided on the second connecting portion corresponding to the guide posts. The connecting ring and the elastic element are both sleeved on the guide posts, and the elastic element abuts against the connecting ring.

[0008] In one possible implementation, the fixing plate is bent on both sides to form a protective portion, the protective portion abutting against the edge of the second connecting portion, and the protective portion having a clearance groove corresponding to the connecting ring.

[0009] In one possible implementation, a rotating column is connected to the top of the protective part, and the control element is rotatably connected to the rotating column.

[0010] In one possible implementation, the control element includes a vertically connected pressing section and a toggle section, the pressing section abutting against the second connecting portion, and the toggle section extending outside the housing, wherein toggling the toggle section causes the pressing section to press / release the second connecting portion.

[0011] In one possible implementation, a recess is provided on the surface of the housing corresponding to the actuating section.

[0012] This utility model's technical solution employs an L-shaped control component. The pressing section abuts against the second connecting part, while the toggle section extends out of the housing. Combined with a rotating column, it achieves effortless operation. The locking and unlocking states of the toggle section are clearly visible, eliminating the need for repeated pressing for confirmation. The first and second connecting parts are connected via planar contact. Compared to traditional plug-in connectors, planar connections allow for more spring pins on the plane, significantly increasing the configurable pin count. The guide column and connecting ring ensure linear movement of the second connecting part. The fixed plate protects against offset and provides a clearance groove to prevent interference. The recessed part of the housing conceals the toggle section, preventing accidental activation. Under normal conditions, the elastic element keeps the insertion gap open for easy insertion and removal. When the lever is pressed down, the lever principle amplifies the force, allowing the second connecting part to stably clamp the plug. This design offers comprehensive advantages such as effortless operation, reliable connection, and long service life, making it particularly suitable for industrial scenarios requiring frequent insertion and removal and high reliability.

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Reference Figures 1 to 4 This utility model proposes a button-type locking connector, including a socket assembly 1 and a plug assembly 2. The socket assembly 1 has a first connecting part 11 protruding from it. The plug assembly 2 includes a housing 21, and a mounting cavity 3 is formed inside the housing 21. A fixing plate 4 and a second connecting part 31 are arranged adjacent to each other in the mounting cavity 3. An elastic member 5 is connected to the wall of the mounting cavity 3 of the second connecting part 31. The elastic member 5 can push the second connecting part 31 to form a mating gap 6 between it and the fixing plate 4. The first connecting part 11 can be inserted into the mating gap 6. A control member 7 is connected to the side of the second connecting part 31 away from the fixing plate 4. The control member 7 extends out of the housing 21. Moving the control member 7 can press / release the second connecting part 31 to lock / release the first connecting part 11.

[0023] Understandably, the socket assembly 1 has a first connecting portion 11, which in this example is a raised flexible PCB insert for inserting into the plug assembly 2. The housing 21 of the plug assembly 2 has an internal mounting cavity 3 that accommodates a fixing plate 4, a second connecting portion 31, an elastic element 5, and a control element 7. The fixing plate 4 is fixed in the mounting cavity 3 as a static support. The second connecting portion 31 is adjacent to the fixing plate 4, forming a mating gap 6 between them. Initially, the gap is relatively wide, facilitating the insertion of the first connecting portion 11. The elastic element 5 is a spring. In the normal state, the elastic element 5 pushes the second connecting portion 31 away from the fixing plate 4, keeping the mating gap 6 open, i.e., in the unlocked state. When locked, the control element 7 presses against the second connecting portion 31, compressing the elastic element 5, forcing the second connecting portion 31 closer to the fixing plate 4, clamping the first connecting portion 11.

[0024] The control element 7 abuts against the second connecting part 31, with a portion extending outside the housing 21. When moved, it can press the second connecting part 31 to move towards the fixing plate 4, compressing the elastic element 5 and narrowing the insertion gap 6 to clamp the first connecting part 11 to achieve locking; or it can release the second connecting part 31, the elastic element 5 returns to its original position, pushes the second connecting part 31 away from the fixing plate 4, and the insertion gap 6 opens to achieve unlocking. At this time, the first connecting part 11 of the socket can be freely inserted or removed.

[0025] In this example, the second connecting part 31 is a sheet-like structure composed of a PCB board and an insulating board, and it is connected to multiple spring pins 8. When the first and second connecting parts 31 are attached, the spring pins 8 will contact the first connecting part 11 to achieve electrical connection. Since the first and second connecting parts 31 are connected by planar contact, compared with traditional plug-in connectors, planar connection can set more spring pins 8 on the plane, greatly increasing the number of configurable pins; and the use of retractable spring pins 8 improves service life while providing soft protection for the contact points, preventing scratches on the contact points after repeated use. In addition, the housing 21 of the socket assembly 1 and the plug assembly 2 is made of electromagnetic shielding material, realizing EMC function.

[0026] Reference Figures 3 to 4 In one embodiment of the present invention, a plurality of guide posts 32 are provided around the second connecting part 31 in the mounting cavity 3. The second connecting part 31 is provided with a connecting ring 311 corresponding to the guide post 32. The connecting ring 311 and the elastic member 5 are both sleeved on the guide post 32, and the elastic member 5 abuts against the connecting ring 311.

[0027] Understandably, the mounting cavity 3 has multiple guide posts 32 around its perimeter. These are cylindrical metal or plastic posts, fixed to the wall of the mounting cavity 3. The second connecting part 31 is a movable component that forms an insertion gap 6 with the fixing plate 4. Its edge has an annular structure that fits onto the guide posts 32. The elastic element 5 is also fitted onto the guide posts 32, with one end abutting against the connecting ring 311 and the other end abutting against the wall of the mounting cavity 3 or the base of the guide post 32. Under normal conditions, the elastic element 5 pushes the connecting ring 311 and the second connecting part 31 away from the fixing plate 4, opening the insertion gap 6.

[0028] The primary function of the guide post 32 and the connecting ring 311 is to provide guidance. The guide post 32 passes through the connecting ring 311, ensuring that the second connecting part 31 can only move axially, avoiding skewing or jamming. It also positions the elastic element 5. The spring is sleeved on the guide post 32 and transmits the elastic force through the connecting ring 311, making the movement of the second connecting part 31 more stable. In addition, multiple guide posts 32 are distributed around the second connecting part 31. In this example, there are four, which can balance the pressure and prevent one-sided wear. The second connecting part 31 is raised and lowered by multiple springs, which makes it more stable.

[0029] Reference Figure 3In one embodiment of the present invention, the fixing plate 4 is bent on both sides to form a protective part 41, the protective part 41 abuts against the edge of the second connecting part 31, and the protective part 41 has a clearance groove 42 corresponding to the connecting ring 311.

[0030] Understandably, the protective part 41 is formed by bending the two sides of the fixing plate 4, abutting against the edge of the second connecting part 31, and restricting its lateral displacement. The clearance groove 42 is slotted at the position of the protective part 41 corresponding to the connecting ring 311, avoiding interference with the axial movement of the connecting ring 311. The main functions of the protective part 41 and the clearance groove 42 are as follows: restricting the lateral displacement of the second connecting part 31, the protective part 41 abuts against the edge of the second connecting part 31 to prevent it from tilting due to vibration or external force, ensuring smooth insertion and removal; avoiding interference with the movement of the connecting ring 311, the clearance groove 42 provides movement space for the connecting ring 311, allowing it to slide freely along the guide post 32 without being blocked by the protective part 41; and enhancing structural strength, the protective part 41 formed by bending the fixing plate 4 can improve the overall rigidity and prevent deformation.

[0031] Reference Figure 3 In one embodiment of this utility model, a rotating column 43 is connected to the top of the protective part 41, and the control component 7 is rotatably connected to the rotating column 43.

[0032] Understandably, the top of the protective part 41 of the fixed plate 4 is provided with a rotating column 43. The control member 7 rotates through this rotating column 43, thereby controlling the locking and unlocking of the second connecting part 31 with less effort. The control member 7 is hinged to the protective part 41 through the rotating column 43, forming a lever structure. When the control member 7 is pressed down, it pushes the second connecting part 31 to move towards the fixed plate 4 to lock it. When the control member 7 is pushed up, the elastic member 5 resets, and the second connecting part 31 rises to unlock it. The lever principle amplifies the force, reduces the operating intensity, and saves more effort.

[0033] Reference Figures 2 to 4 In one embodiment of the present invention, the control member 7 includes a pressing section 71 and a toggle section 72 connected vertically. The pressing section 71 abuts against the second connecting part 31, and the toggle section 72 extends to the outside of the housing 21. Toggle the toggle section 72 can cause the pressing section 71 to press / release the second connecting part 31.

[0034] Understandably, the control element 7 is an L-shaped lever structure. The pressing section 71 is a vertical part that directly abuts against the upper surface of the second connecting part 31. Its shorter length ensures sufficient pressure transmission. The actuating section 72 is a horizontal part that extends from the side of the housing 21. Its length is many times that of the pressing section 71, forming a force-saving lever. When the actuating section 72 extending from the housing 21 is actuated downwards, the lever rotates around the rotating column 43 as the fulcrum. The pressing section 71 presses down on the second connecting part 31, compressing the elastic element 5, reducing the insertion gap 6, and locking the first connecting part 11. When the actuating section 72 is actuated upwards, the pressing section 71 releases the second connecting part 31, the elastic element 5 rebounds, pushing the second connecting part 31 upwards, and the insertion gap 6 reopens.

[0035] In addition to saving effort, compared to traditional button connectors, the locking and unlocking status of the toggle segment 72 is more noticeable, eliminating the need for repeated pressing for confirmation.

[0036] Reference Figures 2 to 3 In one embodiment of this utility model, a recessed portion 22 is provided on the surface of the housing 21 corresponding to the actuating section 72.

[0037] Understandably, the recess 22 is located on the surface of the housing 21 in the area directly opposite the movement trajectory of the toggle segment 72. It serves to accommodate the toggle segment 72, allowing it to retract completely into the recess 22 in the locked state, resulting in a smoother connector appearance; it also prevents accidental collisions with the toggle segment 72 by external objects, thus avoiding misoperation; the edge of the recess 22 forms a natural finger positioning groove, facilitating quick location of the operating position; and it limits the range of motion of the toggle segment 72, preventing excessive toggle movement from damaging the internal structure.

[0038] This utility model's technical solution employs an L-shaped control component 7, with a pressing section 71 abutting against the second connecting part 31 and a toggle section 72 extending out of the housing 21. This, combined with a rotating column 43, enables effortless operation. The locking and unlocking states of the toggle section 72 are clearly visible, eliminating the need for repeated pressing for confirmation. The first and second connecting parts 31 are connected via planar contact. Compared to traditional plug-in connectors, planar connections allow for more spring pins 8 on the plane, significantly increasing the configurable pin count. The guide column 32 and connecting ring 311 ensure linear movement of the second connecting part 31. The fixing plate 4 protects the part 41, limiting offset and providing a clearance groove 42 to prevent interference. The recessed part 22 of the housing 21 conceals the toggle section 72, preventing accidental activation. Under normal conditions, the elastic element 5 keeps the insertion gap 6 open for easy insertion and removal. When the lever is pressed down, the lever principle amplifies the force, allowing the second connecting part 31 to stably clamp the plug. This design offers comprehensive advantages such as effortless operation, reliable connection, and long service life, making it particularly suitable for industrial scenarios requiring frequent insertion and removal and high reliability.
