Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an elastic self-locking anti-detachment connector. Background Technology

[0002] Terminal blocks are basic components used for electrical connections, typically made of an insulating shell and a metal conductor. They achieve circuit continuity by tightening screws to crimp wires, and are widely used in distribution boxes, circuit boards, and other similar applications. Their core drawback lies in their reliance on screws to mechanically fix wires. This requires tools, and the tightening force is difficult to standardize, potentially leading to poor contact or stripped threads. They also lack quick-plugging and self-locking features, are prone to loosening in vibrating environments, and repeated tightening accelerates metal fatigue, resulting in poor long-term reliability. Utility Model Content

[0003] The main purpose of this utility model is to provide a flexible self-locking anti-dislodgement connection terminal, which aims to achieve quick insertion and removal, and the flexible self-locking after wiring greatly improves the ease of use.

[0004] To achieve the above objectives, this utility model proposes an elastic self-locking anti-detachment connection terminal, comprising:

[0005] The housing has multiple wiring channels linearly formed on its surface. The housing has movable cavities corresponding to the wiring channels inside its interior. A guide plate is provided at the bottom of the movable cavity. The edge of the guide plate is bent to form a connecting part, and the connecting part fits into the wiring channel. A connection port is provided on the side of the wiring channel near the connecting part, and an abutment port is provided on the side of the wiring channel away from the connecting part.

[0006] The control component includes an abutment rod, a pressing rod, and an elastic element. One end of the abutment rod is movably inserted into the abutment interface and can extend into the wiring channel, while the other end abuts against the elastic element. An adjustment groove is provided on the surface of the abutment rod, and the end of the pressing rod can press against the side wall of the adjustment groove to drive the abutment rod to move away from the connection interface.

[0007] In one possible implementation, the wall of the adjustment groove is sloped, and the end of the pressing rod is provided with a pressing head that can fit into the adjustment groove.

[0008] In one possible implementation, the surface of the housing is provided with a pressing hole, and one end of the pressing rod away from the pressing head extends from the pressing hole to the outside of the housing.

[0009] In one possible implementation, the wall of the movable cavity is provided with a spring cylinder, and the elastic element is disposed inside the spring cylinder.

[0010] In one possible implementation, a stop ring is provided circumferentially on the surface of the pressing rod, and the stop ring can abut against the edge of the pressing hole.

[0011] This utility model's technical solution achieves automatic wire clamping by employing a press-type elastic self-locking mechanism, allowing for single-handed operation without tools and significantly improving wiring efficiency. The wedge-shaped structure with a pressing head on the beveled surface converts vertical pressing force into horizontal displacement, and the precise limiting of the stop ring ensures effortless operation. The design of continuous pressing by the contact of the conductive plate and the elastic element makes the connection more reliable and eliminates the risk of screw loosening. All moving parts are precisely guided by the housing, ensuring long-term stable operation in vibration environments. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1 to 2This utility model proposes an elastic self-locking anti-detachment connection terminal, characterized in that it includes a housing 1 and a control component. The surface of the housing 1 has multiple wiring channels 2 linearly opened. The interior of the housing 1 has a movable cavity 3 corresponding to the wiring channels 2. A guide plate 4 is provided at the bottom of the movable cavity 3. The edge of the guide plate 4 is bent to form a connecting part 41, and the connecting part 41 fits into the wiring channel 2. A connection port 21 is opened on the side of the wiring channel 2 near the connecting part 41, and an abutment port 22 is opened on the side of the wiring channel 2 away from the connecting part 41. The control component includes an abutment rod 5, a pressing rod 6, and an elastic element 7. One end of the abutment rod 5 is movably inserted into the abutment port 22 and can extend into the wiring channel 2. The other end abuts against the elastic element 7. An adjustment groove 51 is opened on the surface of the abutment rod 5. The end of the pressing rod 6 can press the side wall of the adjustment groove 51 to drive the abutment rod 5 to move away from the connection port 21.

[0020] Understandably, the surface of the housing 1 has multiple wiring channels 2 for inserting wires, and the interior has a movable cavity 3 corresponding to each wiring channel 2. A conductive plate 4 is installed at the bottom for conducting electricity, and its edge is bent to form a connecting part 41, which contacts the wire. There are openings on both sides of the wiring channel 2. The connecting port 21 is used for the wire to make contact with the connecting part 41 after insertion and conduction; the abutment port 22 is used for the abutment rod 5 of the control component to extend into.

[0021] The control component is a self-locking mechanism, consisting of an abutment rod 5, a pressing rod 6, and an elastic element 7, which enables the clamping and releasing of the wire. One end of the abutment rod 5 is inserted into the abutment interface 22, extending into the wiring channel 2 to press the wire, while the other end is held in place by the elastic element 7 (such as a spring) to provide clamping force. The rod body has an adjustment groove 51 for linkage with the pressing rod 6. When the pressing rod 6 is pressed down, its end pushes against the side wall of the adjustment groove 51, forcing the abutment rod 5 to retract and move away from the connection port 21, thereby releasing the wire. In the normal state, the elastic element 7 pushes the abutment rod 5 forward, clamping the wire between the abutment rod 5 and the connection part 41, achieving self-locking and preventing it from falling off.

[0022] During wiring, the wire is inserted into the wiring channel 2, and the abutment rod 5 automatically clamps the wire under the action of the elastic element 7, forming a stable conductor. To disconnect, press the pressing rod 6; the abutment rod 5 retracts to release the wire, allowing for quick operation without tools. Compared to traditional screw terminals, no screws are needed; the internal elastic structure automatically clamps the wire, preventing vibration and loosening. It allows for quick insertion and removal; simply press to disconnect, improving maintenance efficiency.

[0023] Reference Figures 1 to 2 In one embodiment of the present invention, the wall surface of the adjusting groove 51 is formed with a slope 52, and the end of the pressing rod 6 is provided with a pressing head 61, which can fit into the adjusting groove 51.

[0024] Understandably, at least one side wall of the adjusting groove 51 of the abutment rod 5 is designed as an inclined slope, similar to a wedge structure. The function of the slope is to convert the vertical downward pressure of the pressing rod 6 into the horizontal displacement of the abutment rod 5, thereby controlling the clamping or releasing of the wire. The end of the pressing rod 6 is provided with a pressing head 61, which also has an inclined structure. Its shape fits tightly against the slope 52 of the adjusting groove 51, ensuring that when the pressing rod 6 is pressed down, the pressing head 61 can slide smoothly along the slope, avoiding jamming or wear.

[0025] When the pressing rod 6 is pressed down, the pressing head 61 contacts the slope 52 of the adjusting groove 51. Due to the inclination angle of the slope, the vertical pressure is decomposed into a horizontal component and a vertical component. The horizontal component pushes the abutment rod 5 to move away from the connection port 21, while the vertical component is borne by the structure of the housing 1 and does not affect the movement of the abutment rod 5. After the pressing rod 6 is released, the elastic element 7 pushes the abutment rod 5 back to its original position, the slope 52 separates from the pressing head 61 again, and the wire is clamped again.

[0026] Reference Figures 1 to 2 In one embodiment of the present invention, a pressing hole 11 is provided on the surface of the housing 1, and the end of the pressing rod 6 away from the pressing head 61 extends out of the pressing hole 11 to the outside of the housing 1.

[0027] Understandably, a pressing hole 11 is provided on the surface of the housing 1, aligned with the internal pressing rod 6, to ensure that the pressing rod 6 can pass through smoothly. The pressing hole 11 is a circular through hole, slightly larger than the diameter of the pressing rod 6, to avoid friction and jamming.

[0028] One end of the pressing lever 6 is connected to the pressing head 61, and the other end extends from the pressing hole 11 to the outside of the housing 1, forming an operable pressing end. The end of the pressing lever 6 extending to the outside can be designed as a flat button, a raised columnar structure, etc., for easy finger pressing. Users can directly press the exposed end of the pressing lever 6 with their fingers to trigger the internal mechanism without tools, achieving rapid release of the wire. After pressing, the abutment rod 5 retracts, and the wire is released; when the pressing lever 6 is released, the elastic element 7 springs back, and the wire is re-clamped.

[0029] Furthermore, the pressing hole 11 can be designed to be recessed to prevent accidental contact that could cause the terminal to come loose.

[0030] Reference Figures 1 to 2 In one embodiment of this utility model, a spring cylinder 31 is provided on the wall of the movable cavity 3, and the spring is disposed inside the spring cylinder 31.

[0031] Understandably, a spring sleeve 31 is provided on the wall of the movable cavity 3 near the end of the abutment rod 5 to accommodate and fix the elastic element 7. Its function is to ensure that the spring extends and contracts in a fixed direction, preventing skewing or jamming; and to prevent excessive compression or stretching of the spring, protecting its elastic properties. The end of the abutment rod 5 is in direct contact with the spring, while the other end of the spring rests against the bottom of the spring sleeve 31.

[0032] Reference Figures 1 to 2 In one embodiment of this utility model, a stop ring 62 is provided circumferentially on the surface of the pressing rod 6, and the stop ring 62 can abut against the edge of the pressing hole 11.

[0033] Understandably, a raised stop ring 62 is provided around the end of the pressing rod 6 near the pressing hole 11, with its outer diameter slightly larger than the diameter of the pressing hole 11. When the pressing rod 6 is raised, the stop ring 62 abuts against the edge of the pressing hole 11, preventing the pressing rod 6 from extending excessively outside the housing 1 and preventing the pressing rod 6 from completely disengaging from the pressing hole 11. This ensures that the pressing head 61 always remains in contact with the adjusting groove 51, limiting the range of motion of the pressing rod 6 and reducing long-term wear.

[0034] This utility model's technical solution achieves automatic wire clamping by employing a press-type elastic self-locking mechanism, allowing for single-handed operation without tools and significantly improving wiring efficiency. The wedge-shaped structure of the beveled surface 52 and the pressing head 61 converts vertical pressing force into horizontal displacement, and with the precise limiting of the stop ring 62, it ensures effortless operation. The design of the conductive plate 4 contacting the elastic element 7 for continuous pressing makes the connection more reliable and eliminates the risk of screw loosening. All moving parts are precisely guided by the housing 1 to ensure long-term stable operation in vibration environments.
