Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an anti-loosening and vibration-resistant connector. Background Technology

[0002] Connectors are devices that connect two active devices to transmit current or signals, and are indispensable components in electronic equipment. They are widely used in various electronic devices, primarily serving the function of transmitting current or signals. In high-intensity, continuous production environments, due to the high physical demands of the equipment, connectors used for connection may loosen due to vibration and other factors, leading to interruptions in current or signal transmission and affecting normal operation.

[0003] Because the connector's internal insulator is made of plastic, while the external connecting parts are made of metal, in existing technology, the plastic and metal materials are generally bonded together. In environments with high vibration loads, if ordinary threaded connectors are used, the bonded plastic and metal materials can easily loosen due to frequent vibration, affecting normal use. Therefore, an anti-loosening structure needs to be added to the connector to prevent it from loosening. Existing anti-loosening connectors use limiting and locking structures to prevent loosening and vibration, but these structures are complex, difficult to install, and their effectiveness in preventing loosening and vibration is limited, with the risk of loosening still present in high-vibration environments.

[0004] Therefore, it is necessary to provide a simple, easy-to-operate, and effective anti-loosening and anti-vibration connector. Utility Model Content

[0005] The purpose of this invention is to provide a simple, easy-to-operate, and effective anti-loosening and anti-vibration connector.

[0006] To achieve the above objectives, this utility model provides an anti-loosening and vibration-damping connector, comprising:

The toothed sleeve is fitted onto the insulating body and slides along the guide groove by the boss until the end of the toothed sleeve away from the first ratchet assembly abuts against the limiting part, and the boss is positioned within the stop groove. The insulating body is made of plastic, while the toothed sleeve and screw can be made of metal. The cooperation between the toothed sleeve and the limiting part, and the cooperation between the boss and the stop groove, ensures a stable connection between the toothed sleeve and the insulating body. On the other hand, the screw has a hollow receiving cavity, and one end of the screw is provided with a second ratchet assembly. The screw is sleeved on the insulating body and slides until the second ratchet assembly engages with the first ratchet assembly, so that the connection between the sleeve and the screw is secure. When this anti-loosening and vibration-damping connector is connected to equipment or other connectors, the terminal assembly is connected to the equipment for signal connection. At the same time, the screw is threaded to the equipment or other connector to wrap around the first and second ratchet assemblies, making the connection between the first and second ratchet assemblies more secure. The engagement between the first and second ratchet assemblies ensures that the screw and nut can only rotate in the locking direction, resulting in good anti-loosening and vibration-damping effects. The anti-loosening and vibration-damping connector of this utility model has a stable and reliable overall structure, is suitable for high-intensity, continuous production vibration environments, and has good anti-loosening and vibration-damping effects.

[0040] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0041] Please see Figures 1 to 4 Please see Figures 1 to 4This utility model provides an anti-loosening and vibration-resistant connector 100, including an insulating body 10, a terminal assembly 20, a toothed sleeve 30, and a screw 40. The insulating body 10 has a hollow mounting cavity 110 for accommodating the terminal assembly 20. The insulating body 10 has a guide groove 11 for guiding, and a limiting part 12 for limiting positioning at one end. A stop groove 13 is also provided between the guide groove 11 and the limiting part 12. The terminal assembly 20 includes multiple terminal pieces 21, which are installed within the mounting cavity 110. The toothed sleeve 30 has a hollow cavity 301, through which it can be mounted on the insulating body 10. A boss 33 protrudes from the cavity 301, and a first ratchet assembly 31 is provided at one end of the toothed sleeve 30. When installing the toothed sleeve 30, the toothed sleeve 30 is fitted onto the insulating body 10 and slid along the guide groove 11 by the boss 33 until the end of the toothed sleeve 30 away from the first ratchet assembly 31 abuts against the limiting part 12, and the boss 33 is positioned within the stop groove 13. The boss 33 being positioned within the stop groove 13 allows the toothed sleeve 30 to be securely placed on the insulating body 10, enabling better engagement with the screw 40. The screw 40 is provided with a hollow receiving cavity 401, which allows the screw 40 to be installed on the insulating body 10. A second ratchet assembly 41 is provided at one end of the screw 40. When installing the screw 40, the screw 40 is fitted onto the insulating body 10, with the end of the screw 40 with the second ratchet assembly 41 facing the first ratchet assembly 31. Then, the screw 40 is slid until the second ratchet assembly 41 engages with the first ratchet assembly 31 to form a first connecting end for connection. The first connecting end includes one end of the terminal assembly 20 within the mounting cavity 110, and also includes a threaded portion 42 on the screw 40, which is used for threaded connection with other connectors. It is understood that the insulating body 10 used to mount the terminal assembly 20 is made of an insulating material, such as plastic. For better and more secure connection with other connectors, the connection structure is preferably made of metal. Therefore, a metal screw 40 is provided on the insulator. To ensure a more secure connection between the screw 40 and the insulating body 10, a toothed sleeve 30 is provided on the insulating body 10. The toothed sleeve 30 and the screw 40 are connected by a first ratchet assembly 31 and a second ratchet assembly 41, resulting in a secure connection and allowing the screw 40 to better connect with other connectors. In this embodiment, the toothed sleeve 30 is also made of metal. For example, one end of the mounting cavity 110 and the terminal assembly 20 are connected to other connectors and are threaded together by nuts and screws 40 on other connectors. The nuts and screws 40 cooperate to make the connection between the first ratchet assembly 31 and the second ratchet assembly 41 more stable. The structure of the entire anti-loosening and anti-vibration connector 100 is more stable and reliable, so as to effectively prevent loosening and vibration.At the same time, the engagement of the first ratchet assembly 31 and the second ratchet assembly 41 allows the screw 40 to rotate only in one direction, that is, in the direction in which the screw 40 is locked with the nut. This makes it difficult for the screw 40 to loosen and separate from the nut, and even tends to make the connection more stable with more vibration, thus making the overall structure more stable and the connection more reliable.

[0042] With the above technical solution, the anti-loosening and vibration-resistant connector 100 of this utility model includes an insulating body 10, a terminal assembly 20, a toothed sleeve 30, and a screw 40. The insulating body 10 has a hollow mounting cavity 110, and a guide groove 11 for guiding the toothed sleeve 30 is formed on the insulating body 10. A limiting part 12 for limiting the position of the toothed sleeve 30 is provided at one end of the insulating body 10. A stop groove 13 is provided between the guide groove 11 and the limiting part 12, and the stop groove 13 is used to cooperate with the toothed sleeve 30 to reinforce the installation of the toothed sleeve 30 on the insulating body 10. The terminal assembly 20 includes multiple terminal pieces 21, which are installed in the mounting cavity 110. The toothed sleeve 30 has a hollow cavity 301, and a boss 33 is protrudingly provided inside the cavity 301. A first ratchet assembly 31 is provided at one end of the toothed sleeve 30. The toothed sleeve 30 is fitted onto the insulating body 10 and slides along the guide groove 11 via the boss 33 until the end of the toothed sleeve 30 away from the first ratchet assembly 31 abuts against the limiting part 12, and the boss 33 is positioned within the stop groove 13. The insulating body 10 is made of plastic, while the toothed sleeve 30 and screw 40 are made of metal. The toothed sleeve 30 engages with the limiting part 12 and also with the stop groove 13 via the boss 33, ensuring a secure connection between the toothed sleeve 30 and the insulating body 10. On the other hand, the screw 40 has a hollow receiving cavity 401, and one end of the screw 40 is provided with a second ratchet assembly 41. The screw 40 is fitted onto the insulating body 10 and slides until the second ratchet assembly 41 engages with the first ratchet assembly 31, ensuring a secure connection between the toothed sleeve 30 and the screw 40, and forming a first connection end for connection. When the first connection end is connected to a device or other connector, the terminal assembly 20 is connected to the device signal. A mating block 18 is provided inside the first connecting end, allowing the first connecting end to better connect to other equipment or other connectors. Simultaneously, the screw 40 is threadedly connected to the equipment or other connector to enclose the first ratchet assembly 31 and the second ratchet assembly 41, making the connection between the first ratchet assembly 31 and the second ratchet assembly 41 more secure. The meshing between the first ratchet assembly 31 and the second ratchet assembly 41 ensures that the screw 40 and the nut can only rotate in the locking direction, providing good anti-loosening and vibration-damping effects. The anti-loosening and vibration-damping connector 100 of this utility model has a stable and reliable overall structure, is suitable for high-intensity, continuous production vibration environments, and has good anti-loosening and vibration-damping effects.

[0043] Please see Figures 2 to 6 and Figure 9 and Figure 10 In some optional embodiments, a protrusion 32 is provided at the end of the toothed sleeve 30 away from the first ratchet assembly 31, protruding in a direction away from the first ratchet assembly 31, and a boss 33 is disposed on the inner surface of the protrusion 32. That is, the boss 33 is disposed on the protrusion 32 and located within the cavity 301. On the other hand, a recess 121 that mates with the protrusion 32 is provided on the limiting part 12. The toothed sleeve 30 abuts against the limiting part 12 and the protrusion 32 is located within the recess 121. The engagement of the protrusion 32 and the recess 121 makes the connection between the entire toothed sleeve 30 and the insulating body 10 more stable. The insulating body 10 also has an inwardly recessed annular groove 14 along its circumference, and a guide block 15 that mates with the protrusion 32 is provided in the annular groove 14. The protrusion 32 slides along the guide block 15 so that the boss 33 slides into the guide groove 11 and slides along the guide groove 11. In this embodiment, the insulating body 10 is generally cylindrical, and the annular groove 14 is formed circumferentially on the outer surface of the insulating body 10. It is understood that the protrusion 32 engages with the guide block 15 so that the boss 33 within the protrusion 32 can better align and slide with the guide groove 11, thereby facilitating better installation. The protrusion 32 can also engage with the recess 121 to restrict the movement of the toothed sleeve 30 circumferentially.

[0044] Please see Figure 5 and Figure 9 In some optional embodiments, the guide groove 11 has a first inclined surface 111 at one end near the stop groove 13. On the other hand, the boss 33 has a second inclined surface 331 at the end away from the first ratchet assembly 31. When the toothed sleeve 30 is installed, the toothed sleeve 30 slides on the insulating body 10 along a certain trajectory through the engagement of the boss 33 and the guide groove 11. When the toothed sleeve 30 slides close to the limiting part 12, the boss 33 slides out of the guide groove 11 to engage with the stop groove 13. The first inclined surface 111 is provided in the guide groove 11, and the second inclined surface 331 is provided on the boss 33. The engagement of the second inclined surface 331 with the first inclined surface 111 allows the boss 33 to slide smoothly out of the guide groove 11.

[0045] Please see Figure 1 , Figure 5 and Figure 6In some optional embodiments, a housing 50 is also included. One end of the insulating body 10 with an annular groove 14 is located inside the housing 50, and the annular groove 14 reinforces the connection between the insulating body 10 and the housing 50. It is understood that the housing 50 is in-mold injection molded with the entire connection structure 102, and the housing 50 encloses the annular groove 14 to better integrate with the insulating body 10, resulting in a more stable and reliable overall structure. Simultaneously, the housing 50 can also limit the operating portion 43 on the screw 40, thereby making the entire anti-loosening and anti-vibration connector 100 structure more compact and robust. Furthermore, a second connection end for connection is formed at the housing 50, which can be used for connecting cables or other connectors.

[0046] Please see Figures 3 to 6 and Figures 9 to 11 In some optional embodiments, the first ratchet assembly 31 includes a plurality of first steep ramps 312 and a plurality of first gentle ramps 311, which are spaced apart and connected end-to-end. Conversely, the second ratchet assembly 41 includes a plurality of second steep ramps 412 and a plurality of second gentle ramps 411, which are spaced apart and connected end-to-end. Specifically, when the second ratchet assembly 41 engages with the first ratchet assembly 31, the first steep ramps 312 engage with the second steep ramps 412, and the first gentle ramps 311 engage with the second gentle ramps 411. The first steep ramps 312 limit the second steep ramps 412, so that the screw 40 can only slide unidirectionally along the first gentle ramps 311 via the second gentle ramps 411. When the connecting assembly 101 and the screw 40 rotate relative to each other, the rotational resistance in the direction where the first gentle ramps 311 and the second gentle ramps 411 engage is small, and rotation is easy. The first steep slope 312 and the second steep slope 412 have high rotational resistance in the direction of their engagement, making rotation difficult. This achieves a unidirectional orientation effect, making it difficult for the connector nut connected to the screw 40 to detach from each other, and ensuring a stable and reliable overall structure.

[0047] Please see Figures 5 to 7 In some optional embodiments, a fixing part 16 for fixing the terminal assembly 20 is provided in the mounting cavity 110, and the fixing part 16 has a plurality of mounting holes 17 for mounting the terminal pieces 21. The terminal pieces 21 are provided with a stop part 211 and a rib 212. A stop platform 171 that mates with the stop part 211 is provided in the mounting hole 17, and an inner hole 172 that mates with the rib 212 is provided at one end of the mounting hole 17. Specifically, the terminal piece 21 is installed in the mounting hole 17, with the stop part 211 located within the stop platform 171, and the rib 212 and the inner hole 172 are press-fitted. Thus, the terminal assembly 20 is formed in the mounting cavity 110. The rib 212 has a gradually increasing cross-sectional area in the mounting direction, allowing the rib 212 to be more securely connected to the inner hole 172.

[0048] like Figures 1 to 11 As shown, the anti-loosening and vibration-resistant connector 100 of this utility model includes an insulating body 10, a terminal assembly 20, a toothed sleeve 30, a screw 40, and a housing 50. The insulating body 10 has a hollow mounting cavity 110, and a guide groove 11 is formed on the insulating body 10 for guiding the toothed sleeve 30. A limiting part 12 is provided at one end of the insulating body 10 for limiting and fixing the mounting position of the toothed sleeve 30. A stop groove 13 is provided between the guide groove 11 and the limiting part 12, and the stop groove 13 is used to cooperate with the toothed sleeve 30 to reinforce the mounting of the toothed sleeve 30 on the insulating body 10. The terminal assembly 20 includes multiple terminal pieces 21, which are installed within the mounting cavity 110. The toothed sleeve 30 has a hollow cavity 301, and a boss 33 is protruding from the cavity 301. A first ratchet assembly 31 is provided at one end of the toothed sleeve 30. The toothed sleeve 30 is fitted onto the insulating body 10 and slides along the guide groove 11 via the boss 33 until the end of the toothed sleeve 30 away from the first ratchet assembly 31 abuts against the limiting part 12, and the boss 33 is located in the stop groove 13. The insulating body 10 is made of plastic, while the toothed sleeve 30 and screw 40 are made of metal. The toothed sleeve 30 engages with the limiting part 12, and also engages with the recess 121 via the protrusion 32, and with the stop groove 13 via the boss 33, making the connection between the toothed sleeve 30 and the insulating body 10 secure. On the other hand, the screw 40 is provided with a hollow receiving cavity 401, and one end of the screw 40 is provided with a second ratchet assembly 41. The screw 40 is fitted onto the insulating body 10 and slides until the second ratchet assembly 41 engages with the first ratchet assembly 31, making the connection between the toothed sleeve 30 and the screw 40 secure and forming a first connection end for connection. When the first connection end is connected to a device or other connector, the terminal assembly 20 is connected to the device signal. Meanwhile, the screw 40 is threaded into the equipment or other connector to enclose the first ratchet assembly 31 and the second ratchet assembly 41, making the connection between the first ratchet assembly 31 and the second ratchet assembly 41 more secure. The meshing between the first ratchet assembly 31 and the second ratchet assembly 41 ensures that the screw 40 and the nut can only rotate in the tightening direction, providing good anti-loosening and vibration-damping effects. The outer shell 50 and the insulating body 10 are in-mold injection molded, resulting in a stable structure and reliable connection. The anti-loosening and vibration-damping connector 100 of this invention has a stable and reliable overall structure, is suitable for high-intensity, continuous production vibration environments, and provides excellent anti-loosening and vibration-damping effects.
