Description

Technical Field

[0001] This utility model relates to the technical field of electrical equipment, and in particular to an anti-disconnection connector. Background Technology

[0002] Generally, in static environments, mating connectors can prevent loosening through friction between them. However, in dynamic or frequently vibrating environments, friction alone is insufficient to prevent loosening. Therefore, nuts and threads are often used to secure them together, providing a more reliable guarantee against separation. A related technology, disclosed in CN111952780A, describes an anti-loosening connector for mating with a corresponding connector. The connector comprises a tube body, a nut sleeve, and a resilient clamping ring. Multiple terminals are disposed within the tube body. The nut sleeve is fitted over the tube body and has a thread for screwing the corresponding connector. The resilient clamping ring surrounds the nut sleeve and is positioned between the tube body and the nut sleeve. One of the tube body and the nut sleeve has a polygonal annular surface. The resilient clamping ring is fixedly connected to the other end of the tube body and the nut sleeve, and presses against the polygonal annular surface. The polygonal annular surface provides multiple contact points for the resilient clamping ring to prevent loosening due to relative rotation between the tube body and the nut sleeve. While the anti-disengagement connectors in the aforementioned technologies improve the stability of the connectors, there are still some challenges in terms of self-locking of the terminals after mating, especially in situations where frequent wiring is required or the terminals may be subject to vibration. Utility Model Content

[0003] This invention solves the problems in related technologies and proposes an anti-detachment connector. It fixes the wiring terminals with a protective shell, maintains the tension connection with the external device with a tension component, and locks the wiring terminals with a self-locking component, thereby achieving a stable and non-detachable connection effect.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an anti-disconnection connector, comprising a junction box and an anti-disconnection connector electrically connected to the junction box; The anti-detachment connector includes a protective housing fixedly connected to the junction box, terminals slidably connected to the protective housing, a tension assembly connected to each of the terminals, and a self-locking assembly for self-locking the terminals.

[0005] By adopting the above technical solution, this anti-disconnect connector mainly comprises two parts: a junction box and the anti-disconnect connector electrically connected to it. The junction box is a fixed part, providing internal space for connecting power lines. The anti-disconnect connector consists of a protective housing, terminals, a tension assembly, and a self-locking assembly. The protective housing is fixed to the junction box, protecting the internal electronic components. The terminals slide within the protective housing, allowing connection to external devices. The tension assembly ensures appropriate tension between the terminals and the external device, guaranteeing a stable connection. The self-locking assembly locks the terminals during wiring, preventing accidental disengagement.

[0006] As a preferred embodiment, the tension assembly includes a sliding rod slidably connected to each of the terminals, a limiting baffle fixedly disposed at one end of the sliding rod, and a first tension spring disposed on the outer periphery of the sliding rod. One end of the sliding rod is electrically connected to the junction box, and the other end of the sliding rod is electrically connected to the terminal.

[0007] By adopting the above technical solution, the sliding rod can be slidably connected to the terminal block, ensuring both connection flexibility and providing a certain mechanical tension during power transmission. A limit baffle is fixedly installed at one end of the sliding rod to restrict excessive sliding of the terminal block, preventing damage or breakage of the power transmission line. A first tension spring is sleeved on the outer circumference of the sliding rod, providing a certain elastic force to the terminal block, ensuring a stable power connection and adaptability to certain mechanical stresses. One end of the sliding rod is electrically connected to the junction box, and the other end is electrically connected to the terminal block, enabling power transmission between the junction box and the terminal block.

[0008] As a preferred embodiment, the limiting baffle is made of insulating material, and the outer periphery of the limiting baffle is fixedly connected to the protective shell, so that the limiting baffle can facilitate the fixed installation of the sliding rod.

[0009] By adopting the above technical solution, the interaction between the sliding rod and the limit baffle ensures that the terminal block remains within a safe range during sliding, while also ensuring the normal operation of the tension spring, thereby stabilizing the tension of the power transmission line and preventing damage or breakage of the line.

[0010] As a preferred embodiment, one end of the first tension spring is fixedly connected to the upper end face of the limiting baffle, and the other end of the first tension spring is fixedly connected to the lower end face of the terminal block.

[0011] By adopting the above technical solution, the limiting baffle provides necessary positioning for the terminal block by fixing one end of the first tension spring. The other end of the first tension spring is connected to the terminal block, applying a certain elastic force to ensure the stability of the connection between the terminal block and the power supply, and to withstand certain mechanical stress. The sliding rod provides a sliding guide for the terminal block, allowing it to move freely along the sliding rod when subjected to tensile or compressive stress.

[0012] As a preferred embodiment, the self-locking assembly includes an adjusting screw connected to the protective housing, an adjusting section disposed at one end of the adjusting screw, a locking block fixedly disposed at the other end of the adjusting screw, a locking groove disposed on the outer periphery of the locking block and adapted to the terminal block, a second tension spring disposed on the outer periphery of the adjusting section, and a stepped hole disposed on the protective housing and communicating with the terminal block. The adjusting section and the stepped hole are connected by a threaded structure.

[0013] By employing the above technical solution, the adjusting screw is connected to the stepped hole via a thread, used to adjust and fix the position of the locking block. The adjusting section moves in or out of the stepped hole through the threaded structure, thereby adjusting the position of the locking block. The locking block has a locking groove that matches the terminal block, used to lock the terminal block and prevent it from loosening. A second tension spring provides a counter-pulling force, helping to firmly fix the locking block to the terminal block. The stepped hole is a hole with different diameters designed on the protective housing for the insertion and removal of the adjusting section.

[0014] As a preferred embodiment, the outer diameter of the locking block decreases sequentially with respect to its direction of penetration into the stepped hole, and the locking groove is circumferentially arranged with the center of the locking block as the center point.

[0015] By adopting the above technical solution and its unique decreasing outer diameter design, it can gradually penetrate into the stepped hole during installation, thus adapting to terminals of different sizes. The locking grooves on the locking block are evenly arranged circumferentially with its center as the center point.

[0016] As a preferred embodiment, one end of the second tension spring is fixedly connected to the inner cavity of the stepped hole, and the other end of the second tension spring is fixedly connected to the inner side of the locking block.

[0017] By adopting the above technical solution, one end of the second tension spring is fixed in the inner cavity of the stepped hole, and the other end is fixedly connected to the inner side of the locking block, thus providing a reverse pulling force. The stepped hole is fixed on the terminal block, providing reliable support and a suitable mounting position for the locking block.

[0027] like Figures 1 to 4 As shown, an anti-disconnect connector includes a junction box 100 and an anti-disconnect connector 200 electrically connected to the junction box 100; Please refer to details. Figure 2 , Figure 3 and Figure 4 The anti-disengagement connector 200 includes a protective housing 21 fixedly connected to a junction box 100, terminals 22 slidably connected to the protective housing 21, a tension assembly connected to each terminal 22, and a self-locking assembly for locking the terminals 22. This anti-disengagement connector 200 mainly comprises two parts: the junction box 100 and the anti-disengagement connector 200 electrically connected to it. The junction box 100 is the fixed part, providing internal space for connecting power lines. The anti-disengagement connector 200 consists of the protective housing 21, terminals 22, tension assembly, and self-locking assembly. The protective housing 21 is fixed to the junction box 100, protecting the internal electronic components. The terminals 22 slide within the protective housing 21 and can be connected to external devices. The tension assembly ensures that appropriate tension is maintained between the terminals 22 and the external device, guaranteeing a stable connection. The self-locking assembly locks the terminals 22 during wiring to prevent accidental disengagement. The working principle is to fix the terminal 22 with the protective shell 21, maintain the tension connection with the external equipment with the tension component, and then lock the terminal 22 with the self-locking component, so as to achieve a stable and non-detachable connection effect.

[0028] Please refer to details. Figure 2 , Figure 3 and Figure 4 The tension assembly includes a sliding rod 32 slidably connected to each terminal 22, a limiting baffle 31 fixedly disposed at one end of the sliding rod 32, and a first tension spring 321 disposed on the outer periphery of the sliding rod 32. One end of the sliding rod 32 is electrically connected to the junction box 100, and the other end of the sliding rod 32 is electrically connected to the terminal 22. The sliding rod 32 can slide onto the terminal 22, thus ensuring the flexibility of the connection and providing a certain mechanical tension during power transmission. The limiting baffle 31 is fixedly disposed at one end of the sliding rod 32 to limit the excessive sliding of the terminal 22 and prevent damage or breakage of the power transmission line. The first tension spring 321 is sleeved on the outer periphery of the sliding rod 32 to provide a certain elastic force to the terminal 22, ensuring stable power connection and adaptability to certain mechanical stress. One end of the sliding rod 32 is electrically connected to the junction box 100, and the other end is electrically connected to the terminal 22, realizing power transmission between the junction box 100 and the terminal 22 through the sliding rod 32. The overall working principle is that reliable power transmission between the junction box 100 and the junction terminal 22 is achieved through the sliding connection of the terminal 22 and the action of the limit baffle 31 and the tension spring, while maintaining the flexibility and stability of the connection and adapting to various mechanical stress environments.

[0029] Please refer to details. Figure 2 and Figure 3 The limiting baffle 31 is made of insulating material, and the outer periphery of the limiting baffle 31 is fixedly connected to the protective shell 21. The limiting baffle 31 facilitates the fixed installation of the sliding rod 32. The interaction between the sliding rod 32 and the limiting baffle 31 keeps the terminal 22 within a safe range during sliding, and also ensures the normal operation of the tension spring, thereby stabilizing the tension of the power transmission line and preventing the line from being damaged or broken.

[0030] Please refer to details. Figure 2 and Figure 3One end of the first tension spring 321 is fixedly connected to the upper end face of the limiting baffle 31, and the other end of the first tension spring 321 is fixedly connected to the lower end face of the terminal 22. The limiting baffle 31 provides necessary positioning for the terminal 22 by fixing one end of the first tension spring 321. The other end of the first tension spring 321 is connected to the terminal 22, applying a certain elastic force to ensure the stability of the connection between the terminal 22 and the power supply, and to withstand certain mechanical stress. The sliding rod 32 provides a sliding guide for the terminal 22, allowing it to move freely along the sliding rod 32 when subjected to tensile or compressive stress. In summary, when the terminal 22 is subjected to mechanical stress, the first tension spring 321, in cooperation with the limiting baffle 31 and the sliding rod 32, not only maintains the stability of the power connection, but also effectively alleviates the externally applied stress, preventing the terminal 22 from being damaged due to excessive stress.

[0031] Please refer to details. Figure 2 and Figure 4 The self-locking assembly includes an adjusting screw 41 connected to the protective housing 21, an adjusting section 411 disposed at one end of the adjusting screw 41, a locking block 42 fixedly disposed at the other end of the adjusting screw 41, a locking groove 421 disposed on the outer periphery of the locking block 42 and adapted to the terminal 22, a second tension spring 4211 disposed on the outer periphery of the adjusting section 411, and a stepped hole 210 disposed on the protective housing 21 and communicating with the terminal 22. The adjusting section 411 and the stepped hole 210 are connected by a threaded structure, and the adjusting screw 41 is connected to the stepped hole 210 by a thread for adjusting and fixing the position of the locking block 42. The adjusting section 411 moves into or out of the stepped hole 210 through the threaded structure, thereby adjusting the position of the locking block 42. The locking block 42 has a locking groove 421 that matches the terminal 22 for locking the terminal 22 and preventing it from loosening. The second tension spring 4211 provides a reverse pulling force, which helps to firmly fix the locking block 42 to the terminal 22. The stepped hole 210 is a hole with different diameters designed on the protective housing 21 for the insertion and removal of the adjustment section 411. The working principle is that rotating the adjusting screw 41 moves the adjustment section 411 within the stepped hole 210, thereby adjusting the position of the locking block 42. This allows the locking groove 421 to fit and lock the terminal 22, achieving stable fixation of the terminal 22. The second tension spring 4211 ensures tight contact and locking force between the locking block 42 and the terminal 22.

[0032] For details, please refer to Figure 2 and Figure 4The outer diameter of the locking block 42 decreases sequentially with its direction of penetration into the stepped hole 210, and the locking groove 421 is circumferentially arranged with the center of the locking block 42 as the center point. This unique design of decreasing outer diameter allows it to gradually penetrate into the stepped hole 210 during installation, thus adapting to terminals 22 of different sizes. The locking groove 421 on the locking block 42 is evenly arranged circumferentially with its center point. Its design aims to ensure that the locking groove 421 remains tangent to the outer circumference of the terminal 22 when the locking block 42 is rotated, effectively gripping the terminal 22 and preventing it from loosening.

[0033] Please refer to details. Figure 4 One end of the second tension spring 4211 is fixedly connected to the inner cavity of the stepped hole 210, and the other end of the second tension spring 4211 is fixedly connected to the inner side of the locking block 42. The fixed position of one end of the second tension spring 4211 within the stepped hole 210 and the fixed connection of the other end to the inner side of the locking block 42 provides a reverse pulling force. The stepped hole 210 is fixed to the terminal block 22, providing reliable support and a suitable mounting position for the locking block 42.

[0034] In this embodiment, when the terminal 22 is connected to an external device during use, the terminal 22 compresses the first tension spring 321, thereby facilitating the sliding of the terminal 22 around the sliding rod 32 as the central axis. When the terminal 22 is subjected to mechanical stress, the first tension spring 321, through its cooperation with the limiting baffle 31 and the sliding rod 32, can not only maintain the stability of the power connection, but also effectively alleviate the external stress and prevent the terminal 22 from being damaged due to excessive stress. By rotating the adjusting screw 41, the adjusting section 411 is moved within the stepped hole 210, thereby adjusting the position of the locking block 42. This allows the locking groove 421 to fit and lock the terminal 22, thus achieving stable fixation of the terminal 22. The second tension spring 4211 ensures tight contact and locking force between the locking block 42 and the terminal 22.

[0035] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
