Description

Technical Field

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

[0002] Existing overvoltage protectors are prone to damage to their internal ceramic components during transportation and use due to tipping or collisions, especially the connecting wires which are easily broken due to excessive bending.

[0003] Traditional protectors lack an effective buffer protection structure, and cannot effectively disperse the impact force when subjected to external impact, affecting the service life of the equipment; in addition, the protection measures at the connection points are insufficient, and long-term use can easily lead to loosening or wear, posing safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a combined overvoltage protector, which solves the problem of overvoltage protectors being unable to protect against tipping over during transportation and transfer. It protects the internal ceramic components through a support frame mechanism and also protects the bends in the connecting wires through a protective mechanism.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a combined overvoltage protector, including a mounting base, a resistor housing, and connecting wires. The resistor housing contains a metal oxide varistor. Support rods are fixed at the four corners of the upper surface of the mounting base. The upper end of the support rods is provided with protrusions. A support frame mechanism is provided above the mounting base. The support frame mechanism is matched and connected to the support rods through the protrusions. A protection mechanism is rotatably connected to the upper end of the support frame mechanism. The protection mechanism is provided at the connection point between the connecting wires and the resistor housing.

[0006] Furthermore: the support frame mechanism includes a fixed frame, and arc-shaped plates are fixed at the four corners of the fixed frame, with the outer arc-shaped end face of the arc plate extending beyond the two sides of the fixed base.

[0007] Furthermore: a connecting rod is rotatably connected to the lower end of the fixed frame, a threaded head is fixed to the upper end of the fixed seat, and the lower end of the connecting rod is threadedly connected to the threaded head.

[0008] Furthermore: Limiting holes are provided at the four corners of the upper end of the fixed frame, and the limiting holes are matched and inserted with the protrusions.

[0009] Furthermore: the protection mechanism includes a rotating rod, which is rotatably connected to both sides of the upper end of the fixed frame. A V-shaped connecting rod is rotatably connected to the upper end of the rotating rod. One end of the V-shaped connecting rod is fixed with a first elastic clamp with a notch, and the other end is fixed with a second elastic clamp with a semi-circular shape.

[0010] Furthermore, the first and second elastic clamps work together to clamp and protect the connecting line located in the middle.

[0011] This invention provides a combined overvoltage protector. Compared with the prior art, it has the following advantages:

[0012] Beneficial effects:

[0013] This combined overvoltage protector, through the coordinated design of the support frame and protection mechanism, can effectively buffer the impact force when it is tipped over during transportation or use, protecting the internal core components; the arc plate design prevents the equipment from directly hitting the ground; the elastic clamp structure can effectively fix and protect the connecting wires, preventing bending damage; the overall structure is stable and reliable, and easy to install and maintain, significantly improving the service life and safety of the overvoltage protector.

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

[0020] Please see Figure 1-4This utility model provides a technical solution: a combined overvoltage protector; specifically composed of a fixed base 1, a resistor housing 2, and a connecting wire 3. A metal oxide varistor and other protective structures are installed inside the resistor housing 2. By connecting the power supply wire of the device to the connecting wire 3, the overvoltage protector provides overvoltage protection for the electrical equipment. This is existing known technology and will not be described in detail here. Support rods 4 are fixed at the four corners of the upper surface of the fixed base 1, and protrusions 8 are fixed on the upper surface of the support rods 4. A support frame mechanism is installed above the fixed base 1. The support rods 4 are matched and connected to the support frame mechanism through the protrusions 8. The support frame mechanism includes a fixed frame 5, and a protective mechanism is rotatably connected to the upper end of the fixed frame 5. The protective mechanism is installed at the connection point between the connecting wire 3 and the resistor housing 2, and it bends and protects the connecting wire 3 and the resistor housing 2, thereby protecting the connecting wire 3.

[0021] The supporting frame mechanism also includes arc-shaped plates 6, which are fixed at the four corners of the fixed frame 5. The outer arc-shaped end face of the arc-shaped plates 6 extends beyond the two sides of the fixed base 1. A connecting rod 13 is rotatably connected to the lower end of the fixed frame 5, and a threaded head 14 is fixed at the upper end of the fixed base 1. The lower end of the connecting rod 13 is threadedly connected to the threaded head 14. At the same time, limit holes 7 are opened at the four corners of the upper end of the fixed frame 5. The limit holes 7 are matched and inserted with the protrusions 8, thus forming a stable support effect. When the overvoltage protector is tilted during transportation or transfer, it is supported by the arc-shaped plates 6 on both sides to prevent the whole from directly contacting the ground. The impact force is transmitted to the fixed frame 5, thereby transferring the force and protecting the important core components such as the internal ceramic parts.

The first elastic clamp 11 has a notch, through which the connecting line 3 can be placed inside the first elastic clamp 11. The second elastic clamp 12 is semi-circular, and the two second elastic clamps 12 can protect the connecting line 3 in the middle.
