Description

Technical Field

[0001] This utility model belongs to the technical field of busbar connectors, specifically relating to an elastic pressure contact structure for a busbar connector. Background Technology

[0002] Busbar trunking is an important power distribution device in modern buildings and industrial facilities, and the reliability and safety of its connections are of paramount importance. Connectors are the core components of the busbar trunking system, responsible for the electrical connection between sections. The performance of their internal elastic pressure contact structure directly affects contact resistance, temperature rise, and long-term operational stability.

[0003] In existing technologies, busbar connectors have an internal elastic pressure contact structure. However, this elastic pressure contact structure is not convenient for adjustment based on the location of the wiring points, which affects the wiring effect. Therefore, it is necessary to design an elastic pressure contact structure for busbar connectors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an elastic pressure contact structure for a busbar connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic pressure contact structure for a busbar connector, comprising a platform, wherein a countersunk through hole is provided at the center of the surface of the platform, and terminal blocks are symmetrically installed at the bottom of the platform;

[0006] An elastic traction assembly is installed on the lower surface of the platform. The elastic traction assembly includes a guide rod fixedly connected to the bottom of the platform, a guide cylinder sleeved outside the guide rod and slidably disposed, a spring installed outside the guide cylinder, and a base fixedly connected to the bottom of the guide cylinder.

[0007] Preferably, the top end of the spring is fixedly connected to the platform, and the bottom end of the spring is fixedly connected to the base.

[0008] Preferably, both the guide cylinder and the guide rod are hollow, and the guide rod and the countersunk hole of the platform are connected.

[0009] Preferably, the base and the guide cylinder are connected, and the surface of the base has mounting holes.

[0010] Preferably, a protective sleeve is fixedly connected to the surface of the platform, and the protective sleeve has an external threaded groove on its outside.

[0011] Preferably, a sealing ring is fitted on the outer part of the protective sleeve, and the protective sleeve and the countersunk through hole are connected.

[0012] Preferably, the platform is fitted with a protective frame that is fixedly connected, and anti-collision pads are symmetrically installed on the surface of the protective frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. An elastic traction component is installed on the lower surface of the platform. Depending on the application, the base of the elastic traction component is placed on the support surface, and a locking device is used to press and fix the base through the mounting hole. When connecting the terminals, the electrician holds the platform and pulls it longitudinally. The guide rod slides relative to the guide cylinder, and the spring undergoes elastic deformation within its elastic limit, moving the busbar terminal to the lower position of the platform. The traction force on the platform is then removed. Under the spring's elastic force, the guide rod slides down relative to the guide cylinder until the platform's terminal block is in contact with the busbar terminal, achieving elastic pressure contact. An extended bolt is used to penetrate the countersunk hole of the platform, as well as the center hole of the guide cylinder and guide rod, extending the insertion end of the extended bolt into the pre-reserved threaded groove on the support surface of the mounting base. The assembly process is simple and has good stability.

[0015] 2. A protective sleeve is fixedly connected to the surface of the platform. The protective sleeve has an external threaded groove. After the wiring is completed, an insulating protective cap can be used to cover the outside of the protective sleeve to protect the extended bolts installed inside the protective sleeve. A protective frame is fixedly connected to the outside of the platform. Anti-collision pads are symmetrically installed on the surface of the protective frame to improve the protective performance.

Under the elastic force of the spring 8, the guide rod 6 slides down relative to the guide cylinder 7 until the terminal block 11 of the platform 1 is in contact with the terminal of the busbar, realizing elastic pressure contact. An extended bolt is used to penetrate the countersunk through hole 10 of the platform 1, as well as the center hole of the guide cylinder 7 and the guide rod 6, extending the insertion end of the extended bolt into the reserved threaded groove of the support surface of the mounting base 9. The assembly process is simple and has good stability.
