Description

Technical Field

[0001] This utility model relates to the field of resistor technology, and in particular to a high-voltage thick-film ceramic resistor. Background Technology

[0002] A high-voltage thick-film ceramic resistor is an electronic component used to limit current or generate resistance. It is made of ceramic material and typically has high voltage withstand capability and large power dissipation capability.

[0003] When installing resistors, the traditional method is to first move the resistor to the desired position and then fix the brackets on both sides of the resistor in the desired position with bolts. However, resistors may malfunction after long-term use. When a resistor malfunctions, it needs to be removed for repair or replacement. However, after removing the resistor, if the bolts are lost, new bolts need to be found to fix the replaced or repaired resistor in the desired position, which increases the workload of the staff.

[0018] 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.

[0019] This utility model provides, for example Figure 1-3The high-voltage thick-film ceramic resistor shown includes a resistor 1. A fixing frame 2 is symmetrically fixedly connected to both ends of the resistor 1. A positioning hole 3 is provided on one side of the fixing frame 2. Fixing components for fixing the position of the fixing frame 2 are symmetrically arranged on both sides of the resistor 1. The fixing components include a mounting base 4 provided at the bottom of the fixing frame 2. A limiting block 5 is inserted and connected inside the positioning hole 3. A positioning block 6 is fixedly connected to the top of the limiting block 5. A fixing member for limiting the movement direction of the limiting block 5 is provided on one side of the limiting block 5. A moving member for moving the position of the limiting block 5 is provided on another side of the limiting block 5.

[0020] It should be noted that the resistor 1 is an RHP type non-inductive high-voltage high-power resistor, and the mounting bracket 2 is L-shaped. The resistor 1 is fixed to the mounting bracket 2 with bolts, thereby fixing the position of the resistor 1 through the mounting bracket 2. The limiting block 5 is adapted to the positioning hole 3 opened on the mounting bracket 2. The width of the positioning block 6 is greater than the width of the positioning hole 3. The position of the mounting bracket 2 is fixed through the positioning block 6 that cannot be used upwards. The mounting base 4 is a cube with a square groove opened on the top. When in use, the mounting bracket 2 is placed on the inner wall of the bottom end of the square groove.

[0021] Specifically, the top of the mounting base 4 is provided with a positioning groove, and the inner wall of the bottom of the positioning groove is threaded with a positioning bolt 7 for fixing the position of the mounting base 4.

[0022] It should be noted that the positioning bolt 7 is used to fix the position of the mounting base 4.

[0023] Specifically, the fastener includes a sliding cavity 8 opened on one side of the mounting base 4, a sliding block 9 is inserted and connected inside the sliding cavity 8, and a limiting block 5 is fixedly connected to one side of the sliding block 9.

[0024] It should be noted that the sliding block 9 is adapted to the sliding cavity 8 to prevent the sliding block 9 from shaking inside the sliding cavity 8 during use, so that the sliding block 9 slides inside the sliding cavity 8 and drives the limiting block 5 to move in the horizontal direction.

[0025] Specifically, the inner wall of one side of the sliding cavity 8 is provided with an insertion hole 10 for the limiting block 5 and the positioning block 6 to pass through the sliding cavity 8, and the limiting block 5 is inserted and connected inside the insertion hole 10.

[0026] Furthermore, when it is necessary to fix the position of the fixing frame 2, the sliding block 9 is moved by the moving part first, and the limiting block 5 and the positioning block 6 are moved through the through hole 10 by the sliding block 9, so that the limiting block 5 and the positioning block 6 are moved into the through hole 10. Then the fixing frame 2 is placed on the top of the mounting base 4. Finally, the sliding block 9 is moved by the moving part, so that the limiting block 5 is moved into the positioning hole 3 opened on one side of the fixing frame 2, and the positioning block 6 is moved to the top of the fixing frame 2.

[0027] Specifically, the moving part includes a spring 11 fixedly connected to the other side of the sliding block 9, and the spring 11 is fixedly connected to the inside of the other side of the sliding cavity 8.

[0028] Specifically, the movable component also includes a movable block 12 fixedly connected to the top of the sliding block 9, and a push block 13 fixedly connected to the top of the movable block 12. The top of the push block 13 is provided with an arc-shaped pressing groove 14.

[0029] It should be noted that the push groove 14 is used for the finger to push the push block 13, which drives the moving block 12 to move. The moving block 12 drives the sliding block 9 to move. The spring 11 is used to push the sliding block 9 towards the side of the limiting block 5. When the sliding block 9 moves towards the side of the spring 11, the spring 11 is compressed and deformed. When the sliding block 9 loses the pushing force towards the side of the spring 11, the spring 11 returns to its original deformation and pushes the sliding block 9 towards the side of the limiting block 5.

[0030] Specifically, a sliding hole 15 is provided on the inner wall of the top of the sliding cavity 8, and the moving block 12 is slidably inserted into the interior of the sliding hole 15.

[0031] It should be noted that the sliding hole 15 is provided to allow the moving block 12 to pass through the sliding cavity 8, thereby enabling the sliding block 9 located inside the sliding cavity 8 to move through the pushing block 13 located outside the sliding cavity 8.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
