Description

Technical Field

[0001] This utility model relates to the field of varistor technology, and in particular to a varistor overload rapid detection fixture. Background Technology

[0002] Varistors, as key components for overvoltage protection, are widely used in electronic equipment, power systems, and other fields. Their performance stability under overload conditions directly affects the overall circuit safety; therefore, testing their overload performance is a necessary step in production quality inspection and R&D testing. With the rapid development of the electronics industry, the production scale of varistors is constantly expanding, placing higher demands on the efficiency, accuracy, and ease of operation of batch testing.

[0003] The existing integrated negative pressure clamping structure of the testing fixture has limitations in terms of rapid fixation and stable contact, and the ease of handling and compatibility with specifications also need to be improved.

[0004] To address this, a rapid overload detection fixture for varistor is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a varistor overload rapid detection fixture to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: A varistor overload rapid detection fixture includes a main body mechanism and a clamping mechanism disposed on the top of the main body mechanism. The main body mechanism includes: a placement plate, pipes disposed on both sides of the bottom of the placement plate, an air pump disposed at one end of the pipes, a hollow groove disposed inside the placement plate, an opening disposed on the top of the placement plate, a silicone ring disposed on the top of the placement plate, and a slot disposed on one side of the silicone ring.

[0007] In some embodiments, support frames are provided on both sides of the bottom of the placement plate, and a fixing bolt is provided on one side of the top of the support frame.

[0008] In some embodiments, a base plate is provided on one side of the support frame, and an anti-slip plate is provided on the bottom of the base plate.

[0009] In some embodiments, the clamping mechanism includes a hydraulic cylinder disposed on one side of the support frame, a mounting plate disposed on the top of the hydraulic cylinder, and a lower pressure plate disposed on one side of the mounting plate.

[0010] In some embodiments, a silicone plate is provided at the bottom of the lower pressure plate, and a rubber ring is provided at the bottom of the silicone plate.

[0011] In some embodiments, a fixing plate is provided at the bottom of the hydraulic cylinder, and a reinforcing plate is provided at the bottom of the fixing plate.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] A rapid overload detection fixture for varistors utilizes a negative pressure adsorption structure formed by an air pump, a hollow groove, and an opening to quickly fix the varistor during use. A silicone ring enhances sealing and cushioning, ensuring stable contact during testing. The slotted design facilitates quick placement and removal.

[0024] Example 1:

[0025] like Figure 1-3 As shown, a varistor overload rapid detection fixture includes a main body 100 and a clamping mechanism 200 installed on the top of the main body 100. The main body 100 includes: a placement plate 101, pipes 102 installed on both sides of the bottom of the placement plate 101, an air pump 103 installed at one end of the pipes 102, a hollow groove 104 opened inside the placement plate 101, and an opening 105 opened on the top of the placement plate 101. The air pump 103 draws air from the bottom of the varistor at the top of the placement plate 101 through the pipes 102 for adsorption and fixation. A silicone ring 106 is bonded to the top of the placement plate 101, and a groove 107 is opened on one side of the silicone ring 106 to keep the varistor inside the silicone ring 106.

[0026] In this embodiment, support frames 108 are installed on both sides of the bottom of the placement plate 101. A fixing bolt 109 is threadedly connected to the top side of the support frame 108.
