[0002] A thickness gauge is an instrument used to measure the thickness of materials and objects. In industrial production, it is often used to continuously or sample the thickness of products, such as steel plates, steel strips, films, paper, metal foils and other materials. The thickness of the surface copper layer and the hole wall copper layer in the circuit board will directly affect the signal integrity of the high-frequency and high-speed circuit board. Therefore, a tester is needed to test the thickness of the surface copper to ensure that it can be used well.

[0003] For example, the utility model with application number CN202020299020.4 discloses a hole copper thickness gauge. The utility model uses a connection line, a test probe and a probe to detect different thicknesses, and can display and record the measured values ​​through the main circuit board and the LCD liquid crystal display for easy observation and data statistics. The set function keys make the hole copper thickness gauge more comprehensive, and the main circuit board driven by the lithium battery can facilitate the portability of the hole copper thickness gauge, so that it is convenient to use. However, the utility model lacks a protective mechanism for the thickness gauge. If the thickness gauge is accidentally dropped during use, it is easy to cause damage, which increases the economic cost of repair or replacement.

[0024] According to the above technical scheme, when in use, the plug end of the connecting line 2 is inserted into the interface at the top of the tester body 1, and then the detection probe 3 at the head end of the connecting line 2 is aimed at the copper surface to perform thickness detection. The detection result is fed back on the display screen on the tester body 1. By bonding protective strips 7 at equal intervals on both sides of the tester body 1, both sides of the tester body 1 are protected. By fixing a fixed ejector pin 4 on the top of the front of the tester body 1, and elastic ejector pin 5 is elastically installed on the bottom of the front of the tester body 1 through a spring 6, the front protection of the tester body 1 is achieved, the control panel and the display screen are protected, and the elastic setting of the elastic ejector pin 5 can not hinder the operation of the staff.

[0025] A heat dissipation fan 14 is installed on the back of the tester body 1, and connecting strips 16 are connected to the two sides of the heat dissipation fan 14 through output pipes 15. The inner side of the connecting strip 16 is connected to the tester body 1, so as to facilitate the heat dissipation of the internal components of the tester body 1. By opening a through hole connected to the outside at the bottom of the tester body 1 and installing a dustproof mesh plate 17 at the through hole, the heat dissipation of the tester body 1 can be achieved while the interior of the tester body 1 can be dust-proofed.
