Description

Technical Field

[0001] This utility model belongs to the technical field of cable installation joints, specifically relating to a multi-core cable installation joint. Background Technology

[0002] In the field of power transmission and distribution, cables, as key carriers of electrical energy, directly affect the stability and reliability of the entire power system through the performance of their installation joints. However, existing cable installation joints typically consist of at least five components: a round nut, a joint body, a sealing bushing, and a waterproof ring. If installed on a sheet metal surface, a corresponding nut is also required, making production and assembly cumbersome and installation inconvenient. Installation involves first passing the threaded end of the joint body through the through hole, then tightening the nut onto the other side of the joint body, followed by using a wrench to secure the nut. Next, the cable is passed through the round nut, inserted into the hole of the sealing bushing according to its diameter, and extended into the equipment. Finally, the round nut is tightened, causing the joint body's petals to inward, thus causing the sealing bushing to grip the cable, achieving both waterproofing and cable securing. This process is quite cumbersome, and existing cable installation joints can only install individual cables, limiting their application. Therefore, a multi-core cable installation joint is urgently needed to solve these problems. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a multi-core cable installation connector.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A multi-core cable installation connector includes a sealing ring with a plurality of core holes. A threaded connector body is installed inside the sealing ring. The threaded connector body includes an assembly slot. The inner top of the sealing ring has an assembly slot corresponding to the assembly slot. The assembly slot is installed in the assembly slot. A straight body is connected to the bottom of the assembly slot. The outer surface of the straight body is threaded. Notches are provided on both sides of the straight body. Elastic buckles are installed on both sides of the notches. A buckle step is provided on the upper side of the elastic buckle.

[0006] Furthermore, a sealing film is provided on the top inner side of the core hole. This structural design can seal the core hole when no cable is installed.

[0007] Furthermore, the sealing ring and the threaded connector body are manufactured as a single injection molded unit. This structural design facilitates manufacturing and simplifies assembly.

[0008] Furthermore, the sealing ring has a waterproof groove on its inner bottom. This structural design improves the sealing effect after installation.

[0009] Furthermore, the thread is a metric thread design, and the threaded connector body is also connected to an auxiliary nut at the thread. This structural design makes the cable installation more secure in special applications.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model adopts integrated molding, and the production is a finished product. Compared with the existing waterproof connectors with four or five parts, each of which requires mold opening, not only is the production cost high, but the entire production and manufacturing process is also long and the corresponding management cost is also high. The integrated design can greatly save labor and management costs. The snap-on installation prevents the possibility of detachment, is not easy to peel off, reduces installation deformation, and makes installation more convenient. By setting multiple core holes, it is easy to install and fix multiple cables at the same time, improving the use effect. Attached Figure Description

[0016] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2 As shown, this utility model discloses a multi-core cable installation connector. A sealing ring 1 has several core holes 2. A threaded connector body 3 is installed inside the sealing ring 1. The threaded connector body 3 includes an assembly seat 4. The top inner side of the sealing ring 1 has an assembly slot 5 corresponding to the assembly seat 4. The assembly seat 4 is installed in the assembly slot 5. The bottom of the assembly seat 4 is connected to a straight body 6. The outer surface of the straight body 6 is provided with threads 7. The two sides of the straight body 6 are provided with notches 8. The two sides of the notches 8 are provided with elastic buckles 9. The upper side of the elastic buckles 9 is provided with a buckle step 10.

[0018] Preferably, a sealing film 11 is provided on the top inner side of the core hole 2. This structural design can seal the core hole 2 when no cable is installed. In practice, other sealing structure shapes for the core hole 2 when no cable is installed can also be considered depending on the specific circumstances.

[0019] Preferably, the sealing ring 1 and the threaded connector body 3 are manufactured as a single injection molded unit. This structural design facilitates manufacturing and simplifies assembly. However, other manufacturing connection structures for the sealing ring 1 and the threaded connector body 3 can also be considered depending on the specific circumstances.

[0020] Preferably, the inner bottom of the sealing ring 1 is provided with a waterproof groove 12. This structural design improves the sealing effect after installation. In practice, other sealing structure shapes of the sealing ring 1 can also be considered depending on the specific circumstances.

[0021] Preferably, thread 7 is a metric thread, and an auxiliary nut is connected to the threaded connector body 3 at thread 7. This structural design makes the cable installation more secure in special applications. In practice, other connection and installation structures with thread 7 can also be considered depending on the specific circumstances.

[0022] In this embodiment, during installation, the threaded connector body 3 is inserted into the mounting hole on the cabinet wall. The elastic buckle 9 first passes inward through the mounting hole, and then the buckle step 10 is locked onto the side wall of the mounting hole. At this time, the waterproof groove 12 on the sealing ring 1 and the cabinet wall are mutually squeezed. Through compression deformation, a sealing space is formed, which can effectively prevent water vapor from entering the equipment through the gap, thus completing the overall end face sealing. By directly inserting the threaded connector body 3 into the cabinet opening, the assembly time is greatly reduced. Finally, a small hole is punched in the sealing film 11, and the cable is introduced into the core hole 2. Multiple cables can be installed according to actual usage requirements.

[0023] In certain special cases, after installing the threaded connector body, an auxiliary nut can be locked at thread 7 for reinforcement to prevent the sealing ring 1 and the threaded connector body 3 from rotating, thus expanding the application range.

[0024] Among them, the elastic buckle 9 may be pulled off during installation due to radial force. The design of adding buckle step 10 perfectly solves the possibility of the sealing ring 1 coming off.

[0025] The sealing ring 1 is made of TPE soft rubber material, and the threaded connector body 3 is made of PA6 hard rubber material. The sealing ring 1 and the threaded connector body 3 are made by double injection molding, which has high production efficiency and does not require manual assembly in the later stage, thus ensuring production capacity and facilitating production.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
