Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a connector with a secondary locking structure. Background Technology
[0002] Connectors, also known as joints and sockets in China, generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals.
[0003] Existing connectors consist of four basic components: contacts, insulators, housings, and accessories. Contacts are the conductive core, enabling circuit connections through terminals, pins, or sockets. Insulators, mostly made of plastic, are used to position and isolate the contacts, ensuring insulation performance. The housing (metal or plastic) provides mechanical protection, guides mating, and provides fixation, adapting to different installation scenarios. Accessories are configured as needed, including locking mechanisms, seals, cable fasteners, etc. Through the coordinated efforts of all components, a stable and secure circuit connection is achieved.
[0004] Connectors on the market achieve high-speed connections by inserting a plug into a socket. However, most connectors, while having a locking mechanism after the plug is inserted into the socket, lack a secondary locking mechanism, which makes the plug prone to loosening and the connection unstable. To address this issue, a connector with a secondary locking mechanism is proposed. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a connector with a secondary locking structure, aiming to improve the problem that the prior art does not have a secondary locking structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A connector with a secondary locking structure includes a first housing and a second housing. The first housing has a notch inside, and the second housing has a plug rotatably connected inside. A connecting mechanism is installed between the first housing and the second housing, and a quick-release assembly is installed on the outside of the first housing. The connecting mechanism includes a plug-in component and a snap-fit component. The plug-in component includes a semi-circular block, which is fixedly connected to the inner side of the first outer shell. The top of the second outer shell has a sliding groove, and the semi-circular block is slidably connected to the middle of the sliding groove. The top of the second outer shell has a sliding groove. As a further description of the above technical solution: The quick-release assembly includes a long rod that is threaded to the outside of the outer casing. One end of the long rod is fixedly connected to a knob, and the other end of the long rod is fixedly connected to a fixing block. As a further description of the above technical solution: The snap-fit assembly includes a snap-fit block, which is slidably connected inside the outer casing. The insert block has a snap-fit groove inside, and the snap-fit block and the snap-fit groove snap-fit into each other. As a further description of the above technical solution: The card block is internally fixedly connected to a retaining ring, and the fixed block is rotatably connected to the inner side of the retaining ring; As a further description of the above technical solution: The outer side of the second outer shell is threaded with a protective shell, and the first outer shell is threaded with the inner side of the protective shell.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figures 1-4 This utility model provides an embodiment of a connector with a secondary locking structure, comprising a first outer shell 1 and a second outer shell 9. The first outer shell 1 and the second outer shell 9 are used to protect the internal structure. The inside of the first outer shell 1 is provided with a notch 18. The inside of the second outer shell 9 is rotatably connected with a plug 15. The first outer shell 1 and the second outer shell 9 are connected to each other by the cooperation of the plug 15 and the notch 18. The notch 18 also provides a limiting function for the plug 15. A connecting mechanism is installed between the first outer shell 1 and the second outer shell 9. The connecting mechanism enables the connector to achieve a secondary locking structure. A quick-release assembly is installed on the outside of the first outer shell 1. The quick-release assembly can prevent accidental dislodgement or accidental contact.
[0013] The connecting mechanism includes a plug-in component and a snap-fit component. The plug-in component includes a semi-circular block 12, which is fixedly connected to the inner side of the outer shell 1. The top of the outer shell 9 has a sliding groove 13, and the semi-circular block 12 is slidably connected to the middle of the sliding groove 13. The semi-circular block 12 is annular in shape to hold the outer shell 1 and the outer shell 9 in place. The cooperation between the sliding groove 13 and the semi-circular block 12 makes the outer shell 1 and the outer shell 9 more secure. The top of the outer shell 9 has a sliding groove 17. When the semi-circular block 12 is slid into the sliding groove 13... When the connector is internal, rotating the outer shell 1 causes it to rotate along with the semi-circular block 12 on the sliding groove 17, making the outer shell 11 and the outer shell 2 more secure. The locking assembly includes a locking block 4, which is slidably connected inside the outer shell 1. The insert block 15 has a slot 16 inside, and the locking block 4 and the slot 16 engage with each other. The sizes of the locking block 4 and the slot 16 match, and the cooperation of the locking block 4 and the slot 16 achieves a secondary locking effect for the connector, forming a double insurance to prevent vibration and ensure stable and safe connection. Reference Figure 5 The quick-release assembly includes a long rod 3, which is threaded to the outside of the outer casing 1. One end of the long rod 3 is fixedly connected to a knob 2, and the other end of the long rod 3 is fixedly connected to a fixing block 5. A retaining ring 6 is fixedly connected inside the retaining block 4. The fixing block 5 is rotatably connected to the inside of the retaining ring 6. The long rod 3 is used to connect the knob 2 and the fixing block 5, and the fixing block 5 is used to connect the long rod 3 and the retaining block 4. A groove is opened inside the retaining block 4, and the size of the groove matches the size of the fixing block 5. A retaining ring 6 is fixedly connected inside the groove. The retaining ring 6 is used to lock the movement range of the fixing block 5. When the knob 2 is rotated, the knob 2 drives the long rod 3, and the long rod 3 controls the fixing block 5 to rotate inside the retaining ring 6, thereby causing the retaining block 4 to separate and fix from the retaining groove 16.
[0014] Reference Figure 1 and Figure 2 The outer side of outer shell 2 9 is threadedly connected to a protective shell 7, and outer shell 1 is threadedly connected to the inner side of the protective shell 7. The protective shell 7 is used to prevent other impurities from entering between outer shell 1 1 and outer shell 2 9, and also serves as an auxiliary connection between outer shell 1 1 and outer shell 2 9. Both sides of outer shell 1 1 are provided with scale lines 10, and both sides of outer shell 2 9 are provided with scale lines 11. When scale lines 10 and 11 are aligned, the semicircular block 12 inside outer shell 1 1 is aligned with the sliding groove 13 on outer shell 2 9. The scale lines are set... This provides operators with clear and intuitive visual guidance, greatly reducing the difficulty and error of alignment operations. A baffle 8 is fixedly connected to the outer periphery of the second outer shell 9, and the protective shell 7 is located above the baffle 8. The baffle 8 is used to prevent the protective shell 7 from falling off. A sealing gasket 14 is installed on the outer periphery of the insert block 15. The sealing gasket 14 is an elastic sealing gasket, which is also used to strengthen the sealing between the first outer shell 1 and the second outer shell 9. Under the action of the elastic sealing gasket, the connection between the first outer shell 1 and the second outer shell 9 will be tightened, making the first outer shell 1 and the second outer shell 9 more secure.
[0015] Working principle: First, align the scale line 10 on outer shell 1 with the scale line 11 on outer shell 9. Simultaneously, the semicircular block 12 inside outer shell 1 will align with the sliding groove 13 on the insert block 15 inside outer shell 9. Then, rotate outer shell 1 by 90°. At this time, the semicircular block 12 will rotate in the sliding groove 17 on the insert block 15. Then, rotate knob 2. Knob 2 controls long rod 3, which will drive the locking block 4 forward, causing it to engage in the locking groove 16 of outer shell 9. This achieves a secondary locking effect on the connector. When outer shell 1... After the first shell 1 and the second shell 9 are snapped together, the protective shell 7 on the second shell 9 can be rotated. The protective shell 7 will play an auxiliary role in the connection between the first shell 1 and the second shell 9, and at the same time protect the gap between the first shell 1 and the second shell 9 from dust. It provides continuous pre-tightening force to ensure stable connection, and can also finely adjust the engagement depth to adapt to installation errors. It requires active force operation to prevent accidental dislodgement and avoid problems such as poor contact and corrosion caused by foreign object intrusion, thereby extending the service life of the connector and ensuring stable operation in various complex environments.
[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
