Description

Technical Field

[0001] This utility model belongs to the field of surge protector technology, specifically relating to an external connection structure for a surge protector short-circuit structure. Background Technology

[0002] Existing surge protector short-circuit structure and external connection structure, such as Figures 1-2 As shown, during assembly, the grounding outer conductor and the grounding inner conductor are first installed together, and then the assembly is installed onto the main housing. The outer conductor and the inner conductor of the assembly must be aligned with the main housing and the main body at the same time, which brings inconvenience to the installation. It is difficult to ensure that the outer conductor and the inner conductor are aligned at the same time. If they are not aligned, it cannot be detected by visual inspection. Once they are pressed tightly, the main housing will be scrapped when rework is required due to poor performance, making it impossible to rework and repair when performance is poor. Therefore, based on the shortcomings of the existing structure, we designed and proposed an external connection structure for the short circuit structure of the surge protector. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as inconvenient installation and inability to rework for repair, by proposing an external connection structure for the short-circuit structure of a surge protector. This external connection structure for the short-circuit structure of a surge protector is quick and convenient to install, easy to debug, convenient to inspect and repair, and will not cause damage to the structure during repair.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an external connection structure for a surge protector short-circuit structure, including a main housing, a main guide body inserted into the main housing, a grounding outer conductor fixedly connected to one side of the main housing, a short-circuit interface penetrating the main guide body corresponding to the axial position of the grounding outer conductor, a through hole penetrating the end of the grounding outer conductor away from the main housing, an inner ground conductor inserted through the through hole, one end of the inner ground conductor inserted into the short-circuit interface, and the other end movably connected to the through hole.

[0006] Furthermore, the grounding inner conductor is movably connected to the through hole of the grounding outer conductor by means of a thread.

[0007] Furthermore, the through hole is provided with an internal thread portion, and the end of the grounding inner conductor is provided with an external thread portion that is adapted to the internal thread portion.

[0008] Furthermore, the through hole is a countersunk hole, and the internal thread portion is located at the bottom of the countersunk hole.

[0009] Furthermore, a countersunk nut is fixed at one end of the grounding inner conductor located on the external thread, and the nut is located inside the through hole.

[0010] The advantages of the external connection structure for the short-circuit structure of the surge protector proposed in this utility model are as follows: The grounding inner conductor of this utility model is detachably installed on the grounding outer conductor, which can be installed or removed from the outside. This makes the installation of the grounding inner conductor convenient and quick, easy to debug and maintain. When the external connection structure for the short-circuit structure of the surge protector malfunctions, the grounding inner conductor can be unscrewed first, and then the main body can be removed without damaging the main shell, ensuring that rework and maintenance can be carried out smoothly.

[0020] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] See Figures 3-4 An external connection structure for a surge protector short-circuit structure includes a main housing 1. A main guide body 2 is inserted into the main housing 1 and is coaxially arranged with the main housing 1. A grounding outer conductor 3 is centrally located on the main housing 1 and is situated on one side of the main housing 1. A short-circuit interface 21 is provided through the main guide body 2 corresponding to the axial position of the grounding outer conductor 3. The short-circuit interface 21 is used to connect a grounding inner conductor 4. A through hole 31 is provided through the end of the grounding outer conductor 3 away from the main housing 1. The through hole 31 is located at the center of the end of the grounding outer conductor 3 and is directly opposite the short-circuit interface 21. A grounding inner conductor 4 is inserted into the grounding outer conductor 3 through the through hole 31. One end of the grounding inner conductor 4 is inserted into the short-circuit interface 21, and the other end is movably connected to the through hole 31.

[0022] To improve the ease of connection of the inner grounding conductor 4, the inner grounding conductor 4 is movably connected to the through hole 31 of the outer grounding conductor 3 by means of threads. The through hole 31 is provided with an internal thread 32, and the end of the inner grounding conductor 4 is provided with an external thread 42 that matches the internal thread 32. To ensure the aesthetics of the outer grounding conductor 3, the through hole 31 is a countersunk hole, and the internal thread 32 is located at the bottom of the countersunk hole. The end of the inner grounding conductor 4 located at the external thread 42 is fixed with a countersunk nut 41, which is located in the through hole 31. After the inner grounding conductor 4 is connected, the nut 41 at its end is completely inserted into the through hole 31, ensuring the flatness of the end of the outer grounding conductor 3.

If the external connection structure malfunctions, the inner grounding conductor 4 can be unscrewed first, followed by removal of the main body 2, without damaging the main housing 1, ensuring smooth rework and repair. Specifically, during assembly, the outer grounding conductor 3 is first pressed into the main housing 1, and the inner grounding conductor 4 is screwed into the main body 1 via external threads. After tightening, the inner grounding conductor 4 is short-circuited. If malfunction occurs, the inner grounding conductor 4 is unscrewed first, followed by removal of the main body 2.
