Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, and in particular to a quick-connect connector for a surge arrester. Background Technology
[0002] A surge arrester is connected between the cable and the ground, usually in parallel with the protected equipment. Surge arresters effectively protect communication equipment; they activate in the event of abnormal voltage to provide protection. When the communication cable or equipment is operating under normal operating voltage, the surge arrester does not function and is considered an open circuit to the ground. However, if a high voltage occurs that threatens the insulation of the protected equipment, the surge arrester immediately activates, diverting the high-voltage surge current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. Once the overvoltage dissipates, the surge arrester quickly returns to its original state, allowing the communication line to operate normally.
[0003] However, existing surge arresters are inconvenient to install, mainly because fixing the surge arrester to the insulator is difficult and inefficient. Utility Model Content
[0004] The purpose of this invention is to provide a quick-connector for surge arresters to solve the technical problem of how to quickly install surge arresters and insulators.
[0005] This utility model is achieved by the following technical solution: a surge arrester quick connector, including a connecting plate, one end of which is provided with a surge arrester fastening assembly for installing the surge arrester body; the other end of which is provided with an insulator mounting assembly for installing an insulator; wherein, the surge arrester fastening assembly is fixed by a snap-fit structure, and the insulator mounting assembly is fixed by a bolt structure.
[0006] Furthermore, the surge arrester fastening assembly includes a frustum-shaped connector, the lower end of which is provided with a guide opening facing the surge arrester body, and a guide post is provided inside the guide opening.
[0007] Furthermore, the connector is also provided with a double helical buckle structure for fixing the surge arrester body.
[0008] Furthermore, the connector is also provided with a sensing conductor, which is connected to the indicator light.
[0009] Furthermore, the insulator mounting assembly includes a first mounting bolt and a second mounting bolt, which are used to mount the insulator.
[0010] Furthermore, the connecting plate is also provided with a bird spike quick spiral interface, and the bird spike quick spiral interface is provided with bird spikes.
[0011] Furthermore, the bird spike quick-connect spiral interface is located between the first mounting bolt and the second mounting bolt.
[0012] Furthermore, the connecting plate is also provided with a compartment for placing the counter.
[0013] Furthermore, the connecting plate is also provided with reinforcing ribs, which extend into the guide column and are connected to the spring inside the surge arrester body.
[0014] The advantages of this utility model are as follows: This utility model uses a connecting plate to fix the surge arrester body at one end and the insulator at the other end, which allows for arbitrary adjustment of the distance between the surge arrester body and the conductor; and the connecting plate facilitates the installation and fixing of the surge arrester and the insulator, improving installation efficiency.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of 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 some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0022] See Figure 1 , Figure 2 A surge arrester quick connector includes a connecting plate 1. One end of the connecting plate 1 is provided with a surge arrester fastening assembly for mounting the surge arrester body 14. The other end of the connecting plate 1 is provided with an insulator mounting assembly for mounting an insulator 13. The surge arrester fastening assembly is fixed by a snap-fit structure, and the insulator mounting assembly is fixed by a bolt structure.
[0023] In this embodiment, the surge arrester fastening assembly includes a frustum-shaped connector 2. The lower end of the connector 2 has a guide opening 10 facing the surge arrester body 14, facilitating the connection of the surge arrester body 14. A guide post 7 is provided within the guide opening 10. Furthermore, the connector 2 is also provided with a double-helix snap-fit structure 8 for fixing the surge arrester body 14. This double-helix snap-fit structure 8 can cooperate with a protrusion on the surge arrester body 14, thereby achieving fastening of the surge arrester body 14 by rotating it.
[0024] In this embodiment, the connector 2 is also provided with an induction conductor 9, which is connected to an indicator light (not shown in the figure). When the upper end of the surge arrester body 6 reaches the designated installation position, it will touch the induction conductor 9 at the installation position, so that the externally visible indicator light will stay on, indicating to the staff below that the surge arrester has been successfully installed.
[0025] In this embodiment, the insulator mounting assembly includes a first mounting bolt 4 and a second mounting bolt 5. The insulator 13 is mounted using the first mounting bolt 4 and the second mounting bolt 5. The connecting plate 1 is also equipped with a bird-proof quick-connect spiral interface 6, which is provided with bird-proof spikes. This bird-proof quick-connect spiral interface 6 is located between the first mounting bolt 4 and the second mounting bolt 5. The insulator 13 is mounted using the first mounting bolt 4 and the second mounting bolt 5, and the surge arrester body 14 is mounted using the double spiral snap-fit structure 8. This not only improves installation efficiency but also allows for a certain gap between the surge arrester body 14 and the insulator 13 at the other end of the connecting plate 1, thus meeting the requirements for use in high-altitude areas.
[0026] In this embodiment, the connecting plate 1 is also provided with a compartment 3 for placing a counter, which can monitor the number of lightning strikes and observe the entire life cycle of the surge arrester.
[0027] In this embodiment, the connecting plate 1 is also provided with a reinforcing rib 12, which extends into the guide post 7 and is connected to the spring 11 in the surge arrester body 14. When the upper end of the surge arrester body 14 reaches the designated position, it will automatically spring down under the action of the spring 11 and cooperate with the double helix buckle structure 8 to fix it stably in this position.
