Description

Technical Field

[0001] This utility model relates to the field of precision mechanical connection technology, and in particular to a heavy-duty connector with an anti-loosening locking structure. Background Technology

[0002] Heavy-duty connectors are key electrical connection components in industrial automation, machinery and transportation. Their main function is to provide a stable and reliable power or signal transmission channel in harsh environments. To ensure the effectiveness of the connection, existing heavy-duty connectors are usually designed with locking mechanisms, such as snap-fit ​​or lever structures, to quickly fix the connector to the mating parts. This design can meet basic connection requirements under normal working conditions.

[0003] However, in many heavy-duty applications, connectors inevitably endure mechanical vibrations or external impacts from equipment operation for extended periods. Under such continuous dynamic loads, the inherent defects of traditional snap-fit ​​locking mechanisms become apparent. Vibration causes minute relative displacements and gaps between locking components. Over time, this cumulative effect gradually wears down the locking points, reduces the locking force, and eventually leads to the locking mechanism becoming loose. Once the connection becomes loose, it can cause signal interruption or unstable power transmission, affecting the normal operation of the equipment. In some demanding applications, it may even lead to serious safety accidents. While existing technologies ensure convenient connections, they cannot guarantee long-term connection reliability under vibration environments.

[0004] Therefore, this utility model proposes a heavy-duty connector with an anti-loosening locking structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, such as the easy loosening of heavy-duty connectors under vibration environment due to the reliance on a single locking structure, low connection reliability, and lack of effective organization and protection of internal circuits, this utility model aims to provide a heavy-duty connector with an anti-loosening locking structure that has been improved in structure and can effectively solve the above problems.

[0006] This utility model provides a heavy-duty connector with an anti-loosening locking structure, including: a housing; a locking mechanism disposed on the housing; and an anti-loosening mechanism.

[0007] The anti-loosening mechanism includes an outer cover with threads.

[0008] Furthermore, the outer casing is equipped with a locking mechanism, which is suitable for engaging and locking with the mating component. The outer cover is threaded to connect with the corresponding connection structure of the mating component through its threads, so as to provide a fastening force to prevent loosening after the locking mechanism is engaged and locked. The outer casing is also equipped with a groove for accommodating the internal connection structure, a line inlet, a line outlet, and an installation port.

[0009] Preferably, the locking mechanism includes a rotating column fixed to the outer casing and a latch rotatably mounted on the rotating column.

[0010] Preferably, the locking mechanism further includes a locking pin, which is disposed on the outer shell and used to position the locking position of the latch.

[0011] Preferably, the locking mechanism further includes a rubber pad, which is disposed on the surface of the latch suitable for contacting the mating component, to enhance the sealing and cushioning effect.

[0012] Preferably, the locking mechanism further includes a protective cover that covers the outside of the latch.

[0013] Preferably, the anti-loosening mechanism further includes a gasket, which is disposed between the outer cover and the corresponding connecting structure to improve the sealing performance of the threaded connection.

[0014] Preferably, the anti-loosening mechanism further includes a conduit for providing a passage for the line, and a stabilizing block for fixing the conduit.

[0015] Preferably, the anti-loosening mechanism is further provided with a slot inside, which is used to accommodate and arrange the internal wiring.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of existing heavy-duty connectors being prone to loosening and having poor connection stability in vibration environments by setting up mutually independent locking mechanisms and anti-loosening mechanisms. It achieves the technical effect of double locking and stable and reliable connection.

[0018] 2. This utility model solves the problems of insufficient sealing leading to internal contamination and hard contact causing wear of locking components in existing connectors by setting a rubber pad at the locking mechanism and a gasket at the threaded connection of the anti-loosening mechanism. It achieves the technical effects of enhancing sealing and dustproof performance, providing buffer to protect components, and improving the product's environmental adaptability and durability.

[0019] 3. This utility model solves the problem that the internal wiring of the connector is easily worn, squeezed or pulled during vibration or plugging and unplugging due to irregular arrangement by setting a through pipe, a stabilizing block and a slot inside the anti-loosening mechanism. It achieves the technical effect of tidying up and protecting the internal wiring and ensuring long-term reliable electrical connection. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a heavy-duty connector with an anti-loosening locking structure, which aims to solve the problem of insufficient locking reliability and easy loosening of existing heavy-duty connectors under vibration environment.

[0029] like Figure 1 and Figure 2As shown, the heavy-duty connector with an anti-loosening locking structure includes a housing 1. The housing 1 is provided with a locking mechanism 3 and an anti-loosening mechanism 4. The housing 1 serves as an integral carrier, providing installation and operating space for the various components of the connector. The locking mechanism 3 is used to achieve initial locking between the connector and the mating component. The anti-loosening mechanism 4 is used to perform secondary tightening of the connection after locking to prevent loosening. The housing 1 has a groove 2 for accommodating the internal connection structure. The housing 1 also has an inlet 47 for external lines to enter and an outlet 36 for internal lines to exit. The housing 1 also has an installation port 37 for fixing related components.

[0030] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the locking mechanism 3 and the anti-loosening mechanism 4 form a structural cooperation and collaborative working relationship.

[0031] Please refer to the following carefully. Figure 3 The locking mechanism 3 will be described in detail below:

[0032] The locking mechanism 3 includes a rotating column 31 fixed to the outer shell 1 and a latch 32 rotatably mounted on the rotating column 31. The locking mechanism 3 also includes a locking post 34 disposed on the outer shell 1 and used to position the latch 32 in the locking position. The latch 32 engages with the docking component by rotating around the rotating column 31. The locking post 34 limits the latch 32 after engagement to ensure the stability of the locking. A rubber pad 35 is also provided on the surface of the latch 32 that is suitable for contact with the docking component. The rubber pad 35 is compressed during locking to enhance the sealing and buffering effect. The locking mechanism 3 is also covered with a protective cover 33, which provides protection for the latch 32 and the internal components such as the rotating column 31.

[0033] Please refer to the following carefully. Figure 4 The following is a detailed description of the anti-loosening mechanism 4:

[0034] The anti-loosening mechanism 4 includes an outer cover 41 with threads 42, which are adapted to be threadedly connected to the corresponding connection structure of the mating component. The outer cover 41 can be tightened by rotating it, thereby providing a strong anti-loosening capability. A gasket 43 is also provided between the outer cover 41 and the corresponding connection structure. The gasket 43 is used to improve the sealing of the threaded connection and further prevent loosening caused by vibration. This combination structure of locking and then tightening the threads ensures the high reliability of the connector under heavy load and vibration conditions.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, in order to organize and protect the internal wiring of the connector, please continue to refer to... Figure 4The anti-loosening mechanism 4 is also provided with a conduit 45 for providing a passage for the line, and a stabilizing block 46 for fixing the conduit 45. The stabilizing block 46 is fixedly connected to the inner wall of the anti-loosening mechanism 4 and clamps and fixes the conduit 45 to ensure the stability of the line passage. The anti-loosening mechanism 4 is also provided with a slot 44, which is used to accommodate and arrange the internal lines passing through the conduit 45 in an orderly manner to avoid the lines being messy or squeezed.

[0037] Working principle: When the heavy-duty connector with anti-loosening locking structure is working, the outer shell 1 serves as the overall carrier, providing installation and operating space for each component. The slot 2 is used to accommodate the internal connection structure. External lines enter the interior of the outer shell 1 through the inlet 47 to start the connection process.

[0038] The locking mechanism 3 enables reliable locking of the connector. The rotating column 31 provides a fulcrum for the locking buckle 32. When the connector is docked, the locking buckle 32 rotates around the rotating column 31 and engages with the docking part to complete the initial locking. The locking column 34 cooperates with the locking buckle 32 to position the locking position and ensure that the locking buckle 32 and the docking part are stably engaged. The rubber pad 35 is set at the locking part to enhance the sealing and buffering effect during locking and avoid damage to the parts caused by hard friction. The protective cover 33 protects the internal components of the locking mechanism 3 and prevents external factors from affecting its normal operation. The outlet 36 leads the wiring inside the housing 1 to the external device. The mounting port 37 facilitates the installation and fixing of related components on the housing 1.

[0039] The anti-loosening mechanism 4 prevents the connector from loosening after locking. The outer cover 41 is threaded to the corresponding connection structure through the screw thread 42. The thread engagement enhances the tightness of the connection. The gasket 43 is placed at the connection part of the screw thread 42 to improve the sealing of the threaded connection, reduce the loosening of the thread caused by vibration, and strengthen the connection stability. The slot 44 accommodates the internal related structures and circuits, so that the circuits are arranged in an orderly manner inside the anti-loosening mechanism 4. The through tube 45 provides a passage for the circuits to pass through, ensuring that the circuits pass smoothly through the anti-loosening mechanism 4 and at the same time, it organizes the circuits. The stabilizing block 46 fixes the through tube 45 and other components to ensure that the through tube 45 remains stable when working.

[0040] After the connector is fully docked, the groove 2 of the outer shell 1 accommodates the internal connection structure. The latch 32 of the locking mechanism 3 is stably engaged with the docking component. The rubber pad 35 helps to enhance the sealing and cushioning of the locking. The outer cover 41 of the anti-loosening mechanism 4 further strengthens the connection through the cooperation of the screw thread 42 and the washer 43 to prevent loosening after locking. The internal circuit enters through the inlet 47, is regulated and protected by the through tube 45, groove 44 and other structures of the anti-loosening mechanism 4, and is then discharged from the outlet 36, realizing a stable circuit connection and transmission. The cooperation of each component makes the heavy-duty connector both reliably locked and has an anti-loosening function, ensuring the connection stability during long-term use.
