Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, specifically a surge protector. Background Technology

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing damage to other equipment in the circuit.

[0003] However, existing surge protectors have the following problems during use: 1. Surge protectors typically use a terminal and screw mating structure to drive the terminals inside the connector. During screw rotation, the position after rotation is unknown, which can easily damage the enameled wire in contact with the terminal, leading to poor contact; 2. Surge protectors are usually installed via a guide rail bracket. Frequent disassembly and reassembly can easily damage the guide rail bracket, requiring replacement of the surge protector and thus increasing its service life. Summary of the Invention

[0004] The purpose of this utility model is to provide a surge protector to solve the following problems mentioned in the background art during the use of existing surge protectors: 1. Surge protectors typically use a terminal and screw mating structure design to drive the terminals in the wiring port. During screw rotation, the position after rotation cannot be known, which can easily damage the enameled wire in contact with the terminal, resulting in poor contact; 2. Surge protectors are usually installed through a guide rail bracket. Frequent disassembly and assembly can easily damage the guide rail bracket, requiring replacement of the surge protector and thus increasing its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surge protector, comprising a base, wherein wiring ports are provided on the front and rear end faces of the base, and a tightening hole is provided on the top surface of the base at a position opposite to the wiring ports, and the tightening hole communicates with the wiring ports; an observation port is provided on the front and rear end faces of the base at a position opposite to the tightening hole, and the observation port communicates with the tightening hole, the observation port being located above the wiring ports; and a mounting base for installation and fixation is snapped onto the bottom of the base.

[0006] Preferably, the base has a connecting cavity, and multiple card interfaces are provided below the surface of the base. A guide groove is provided in the connecting cavity below the card interfaces, and the guide groove communicates with the card interfaces.

[0007] Preferably, a connecting plate is fixedly connected to the top surface of the mounting base, and a snap-fit ​​block is fixedly connected to the surface of the connecting plate at a position opposite to the snap-fit ​​interface, and the snap-fit ​​block snaps into the snap-fit ​​interface.

[0008] Preferably, the snap-fit ​​block is adapted to the snap-fit ​​interface and the guide groove.

[0009] Preferably, a guide rail type connecting seat is fixedly installed at the bottom of the mounting base.

[0010] Beneficial effects

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model allows observation of the approximate position of the screw being tightened downwards within the tightening hole through the observation port, preventing over-tightening during the tightening process, ensuring the safety of the enameled wire, and thus improving electrical contact capability.

[0013] 2. This utility model adopts a modular design for the base and the mounting base, allowing the mounting base to be replaced as needed. If the mounting base is damaged during use, only the mounting base needs to be replaced, thereby reducing the practical cost and improving compatibility. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figure 1-2 This is a schematic diagram of a surge protector according to a preferred embodiment of the present invention. In this embodiment, the surge protector includes a base 1. Wiring ports 2 are provided at both ends of the base 1. A tightening hole 3 is provided on the top surface of the base 1 at a position opposite to the wiring ports 2, and the tightening hole 3 communicates with the wiring ports 2. Observation ports 4 are provided on both ends of the base 1 at a position opposite to the tightening holes 3, and the observation ports 4 communicate with the tightening holes 3. The observation ports 4 are located above the wiring ports 2, and through the observation ports 4, the approximate position of the screw tightened downwards within the tightening holes 3 can be observed. The determination is based on whether the screw is completely tightened downwards within the observation ports 4. The screw is considered not tightened properly if the tightening head is higher than the observation port 4, and over-tightened if the tightening head is lower than the observation port 4. This method prevents over-tightening of the screw during the tightening process, ensuring the safety of the enameled wire and improving electrical contact capability. At the same time, a mounting base 5 for installation and fixation is snapped into the bottom of the base 1. By adopting a modular design for the base 1 and the mounting base 5, the mounting base can be replaced as needed. If the mounting base 5 is damaged during use, only the mounting base 5 needs to be replaced, thereby reducing the practical cost and improving compatibility.

[0022] In this embodiment, the base 1 has a connecting cavity 7, and multiple card interfaces 6 are provided below the surface of the base 1. A guide groove 11 is provided in the connecting cavity 7 below the card interfaces 6, and the guide groove 11 communicates with the card interfaces 6. A connecting plate 8 is fixedly connected to the top surface of the mounting base 5. A snap-fit ​​block 9 is fixed to the surface of the connecting plate 8 at a position opposite to the card interfaces 6, and the snap-fit ​​block 9 snaps into the card interfaces 6, thereby realizing the fixed connection between the mounting base 5 and the base 1.

[0023] In this embodiment, the snap-fit ​​block 9 is adapted to the card interface 6 and the guide groove 11. This structural design reduces the generation of gaps during the engagement of the snap-fit ​​block 9 with the card interface 6 and the guide groove 11.

[0024] In this embodiment, a guide rail type connecting seat 10 is fixedly installed at the bottom of the mounting base 5, and the surge protector is installed through the connecting seat 10.

[0025] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
