[0002] A connector is a device that connects two active devices and is used to transmit current or signals. It is an indispensable component in electronic devices. Connectors are widely used in various electronic devices, mainly for transmitting current or signals and taking on the task of current or signal transmission. In some environments with high-intensity and continuous production, due to the high labor intensity of the equipment, the connectors used for connection may become loose due to vibration or other reasons, resulting in the interruption of current or signals and affecting normal use.

[0003] Since the inside of the connector uses an insulator made of plastic material and the outside part for connection uses a metal material. In the prior art, the plastic material and the metal material are generally bonded and fixed together. For a use environment with a large vibration load, if an ordinary threaded connector is used, due to frequent vibration, the bonded plastic material and metal material are very likely to become loose, affecting normal use. Therefore, it is necessary to add a loosening-preventing structure in the connector to prevent the threaded connector from loosening. The existing loosening-preventing connectors use structures such as limit clamping to prevent loosening and resist vibration, but the structures are complex, the installation is troublesome, and the effect of preventing loosening and resisting vibration is also limited. There is still a risk of loosening in a high-vibration environment.

[0004] Therefore, it is necessary to provide a loosening-preventing and vibration-resistant connector with a simple and stable structure, convenient operation, and effective loosening prevention and vibration resistance. Summary of the Invention

[0047] In order to elaborate on the technical content and structural features of the present invention in detail, the following further description is provided in conjunction with the implementation manners and with reference to the drawings.

[0048] Please refer to Figures 1 to 4, the present invention provides a loosening-preventing and vibration-resistant connector 100, which includes an insulating body 10, a terminal assembly 20, a tooth sleeve 30, a screw 40 and a housing 50. Among them, the insulating body 10 is provided with a hollow mounting cavity 110 for accommodating the terminal assembly 20. A guiding groove 11 for guiding is formed on the insulating body 10, a limiting portion 12 for limiting is provided at one end of the insulating body 10, and a stop groove 13 is also provided between the guiding groove 11 and the limiting portion 12. The terminal assembly 20 includes a plurality of terminal pieces 21, and the plurality of terminal pieces 21 are installed in the mounting cavity 110. The tooth sleeve 30 is provided with a hollow cavity 301, and the tooth sleeve 30 can be installed on the insulating body 10 through the cavity 301. A boss 33 is protrudingly provided in the cavity 301, and a first ratchet assembly 31 is provided at one end of the tooth sleeve 30. When installing the tooth sleeve 30, the tooth sleeve 30 is sleeved on the insulating body 10 and slides along the guiding groove 11 by means of the boss 33 until the end of the tooth sleeve 30 away from the first ratchet assembly 31 abuts against the limiting portion 12, and the boss 33 is located in the stop groove 13. The boss 33 being located in the stop groove 13 can make the tooth sleeve 30 stably placed on the insulating body 10 to better cooperate with the screw 40. The screw 40 is provided with a hollow accommodating cavity 401, and the accommodating cavity 401 enables 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 sleeved on the insulating body 10, and the end provided with the second ratchet assembly 41 faces the first ratchet assembly 31.

It can be understood that the insulating body 10 for installing the terminal assembly 20 is made of insulator material, and the insulating body 10 can be made of materials such as plastic. In order to better and more stably connect with other connectors, the connecting structure is preferably made of metal material. Therefore, a screw 40 made of metal material is provided on the insulator.

The tooth sleeve 30 and the screw 40 are meshed and connected through the first ratchet assembly 31 and the second ratchet assembly 41, so that the connection is stable, and further the screw 40 can better connect with other connectors. In this embodiment, the tooth sleeve 30 is also made of a structure made of metal material. Exemplarily, one end of the mounting cavity 110 and the terminal assembly 20 are connected to other connectors, and are threadedly connected to the screw 40 through a nut on the other connector.

Even with vibration, there is a tendency for the connection to be more stable, thereby making the overall structure more stable and the connection more reliable. On the other hand, the housing 50 is connected to the end of the insulating body 10 away from the gear sleeve 30 and forms a second connection end for connection. The second connection end can be used for connecting cables or other connectors, etc.

[0049] After adopting the above technical solution, the anti-loosening and anti-vibration connector 100 of the present invention includes an insulating body 10, a terminal assembly 20, a tooth sleeve 30, a screw 40, and a housing 50. The insulating body 10 is provided with a hollow installation cavity 110, and a guiding groove 11 for guiding is formed on the insulating body 10. The guiding groove 11 is used to guide the tooth sleeve 30. One end of the insulating body 10 is provided with a limiting portion 12 for limiting, and the limiting portion 12 is used to limit and fix the installation position of the tooth sleeve 30. A stop groove 13 is provided between the guiding groove 11 and the limiting portion 12, and the stop groove 13 is used to cooperate with the tooth sleeve 30 to strengthen the installation of the tooth sleeve 30 on the insulating body 10.

The tooth sleeve 30 is provided with a hollow cavity 301, a boss 33 protrudes inside the cavity 301, and a first ratchet assembly 31 is provided at one end of the tooth sleeve 30. The tooth sleeve 30 is sleeved on the insulating body 10 and slides along the guiding groove 11 by means of the boss 33 until one end of the tooth sleeve 30 away from the first ratchet assembly 31 abuts against the limiting portion 12, and the boss 33 is located in the stop groove 13. The insulating body 10 is made of plastic material, and the tooth sleeve 30 and the screw 40 are made of metal material. The cooperation between the tooth sleeve 30 and the limiting portion 12, and the cooperation between the boss 33 and the stop groove 13 make the connection between the tooth sleeve 30 and the insulating body 10 firm. On the other hand, the screw 40 is provided with a hollow accommodation cavity 401, and a second ratchet assembly 41 is provided at one end of the screw 40. The screw 40 is sleeved on the insulating body 10 and slides until the second ratchet assembly 41 meshes with the first ratchet assembly 31, so that the connection between the tooth sleeve 30 and the screw 40 is firm, and a first connection end for connection is formed. When the first connection end is connected to a device or other connector, the terminal assembly 20 is signal-connected to the device. A fitting block 18 is provided inside the first connection end, so that the first connection end can be better connected to other devices or other connectors. At the same time, the screw 40 is threadedly connected to the device or other connectors to wrap 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 firm, and the meshing between the first ratchet assembly 31 and the second ratchet assembly 41 makes the screw 40 and the nut can only rotate in the locking direction, with good anti-loosening and anti-vibration effects. The housing 50 is connected to one end of the insulating body 10 away from the tooth sleeve 30 and forms a second connection end for connection. The anti-loosening and anti-vibration connector 100 of the present invention has a stable and reliable overall structure, can be applied to a vibration environment of high-strength and continuous production, and has good anti-loosening and anti-vibration effects.

[0050] Please refer to Figures 2 to 6 and Figure 9 and Figure 10, in some alternative embodiments, a protrusion 32 is provided at one end of the gear sleeve 30 away from the first ratchet assembly 31 and protrudes in a direction away from the first ratchet assembly 31. A boss 33 is provided on the inner surface of the protrusion 32. That is, the boss 33 is provided on the protrusion 32 and is located within the cavity 301. On the other hand, a recess 121 is provided on the limiting portion 12 for mating with the protrusion 32. The gear sleeve 30 abuts against the limiting portion 12 and the protrusion 32 is located within the recess 121. The cooperation between the protrusion 32 and the recess 121 makes the connection between the entire gear sleeve 30 and the insulating body 10 more stable. Among them, a circumferentially inwardly recessed annular groove 14 is further provided on the insulating body 10, and a guiding block 15 for mating with the protrusion 32 is retained within the annular groove 14. The protrusion 32 slides along the guiding block 15 so that the boss 33 slides into the guiding groove 11 and slides along the guiding groove 11. In this embodiment, the insulating body 10 is generally in a cylindrical structure, and the annular groove 14 is provided circumferentially on the outer surface of the insulating body 10. It can be understood that the protrusion 32 is used to cooperate with the guiding block 15 so that the boss 33 within the protrusion 32 can be better aligned and slide with the guiding groove 11, thereby enabling better installation. The protrusion 32 can also cooperate with the recess 121 to restrict the movement of the gear sleeve 30 in the circumferential direction.

[0051] Please refer to Figure 5 and Figure 9 , in some alternative embodiments, a first inclined surface 111 is provided at one end of the guiding groove 11 close to the stop recess 13. On the other hand, a second inclined surface 331 is provided at one end of the boss 33 away from the first ratchet assembly 31. When installing the gear sleeve 30, the gear sleeve 30 slides on the insulating body 10 along a certain trajectory through the cooperation between the boss 33 and the guiding groove 11. When the gear sleeve 30 slides close to the limiting portion 12, the boss 33 has to slide out of the guiding groove 11 to engage with the stop recess 13 for clamping cooperation. The first inclined surface 111 is provided in the guiding groove 11, and the second inclined surface 331 is provided on the boss 33. Through the cooperation between the second inclined surface 331 and the first inclined surface 111, the boss 33 can smoothly slide out of the guiding groove 11.

[0052] Please refer to Figure 1 , Figure 5 and Figure 6 , in some alternative embodiments, one end of the insulating body 10 provided with the annular groove 14 is located within the outer shell 50 and the connection between the insulating body 10 and the outer shell 50 is strengthened by means of the annular groove 14. It can be understood that the outer shell 50 and the entire connection structure 102 are injection molded in the mold. The outer shell 50 wraps the annular groove 14 to better combine with the insulating body 10, and the overall structure is more stable and reliable. At the same time, the outer shell 50 can also limit the operating portion 43 on the limiting screw 40, thereby making the structure of the entire anti-loosening and anti-vibration connector 100 more compact and reliable.

[0053] Please refer to Figures 3 to 6 andFigures 9 to 11 , in some alternative embodiments, the first ratchet component 31 includes a plurality of first steep inclined surfaces 312 and a plurality of first gentle inclined surfaces 311, and the plurality of first steep inclined surfaces 312 and the plurality of first gentle inclined surfaces 311 are arranged at intervals and connected end to end. On the other hand, the second ratchet component 41 includes a plurality of second steep inclined surfaces 412 and a plurality of second gentle inclined surfaces 411, and the plurality of second steep inclined surfaces 412 and the plurality of second gentle inclined surfaces 411 are arranged at intervals and connected end to end. Specifically, when the second ratchet component 41 engages with the first ratchet component 31, the first steep inclined surface 312 cooperates with the second steep inclined surface 412, and the first gentle inclined surface 311 cooperates with the second gentle inclined surface 411. The first steep inclined surface 312 is used to limit the second steep inclined surface 412 so that the screw 40 can only slide unidirectionally along the first gentle inclined surface 311 by means of the second gentle inclined surface 411. When the connecting component 101 and the screw 40 rotate relative to each other, the rotation resistance in the direction of the cooperation between the first gentle inclined surface 311 and the second gentle inclined surface 411 is small and the rotation is easy to perform. However, the rotation resistance in the direction of the cooperation between the first steep inclined surface 312 and the second steep inclined surface 412 is large and the rotation is not easy to perform, so as to achieve a unidirectional orientation effect, making the connector nuts connected to the screw 40 not easily separated from each other, and the overall structure is stable and reliable.

[0054] Please refer to Figures 5 to 7 , in some alternative embodiments, a fixing portion 16 for fixing the terminal component 20 is provided in the installation cavity 110, and a plurality of installation holes 17 for installing the terminal members 21 are provided in the fixing portion 16.

A stop platform 171 that cooperates with the stop portion 211 is provided in the installation hole 17, and an inner hole 172 that cooperates with the rib 212 is provided at one end of the installation hole 17. Specifically, the terminal member 21 is installed in the installation hole 17, and the stop portion 211 is located in the stop platform 171, and the rib 212 is in interference fit with the inner hole 172. Furthermore, the terminal component 20 is formed in the installation cavity 110.
