Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, specifically a leakage current switch tester. Background Technology
[0002] A leakage current circuit breaker tester is an instrument used to detect leakage current. It can detect the operating current of current-type electric shock circuit breakers and unbalanced leakage currents below the operating current of current-type electric shock circuit breakers. It can also distinguish between harmful leakage voltages and harmless induced voltages. It is an external, enclosed, independent component connected to the outside of the tester. A worker wearing insulated boots and gloves takes the tester to the danger zone, first using the high-sensitivity setting. After confirming the location of the power source and hearing a high-frequency alarm, the high-sensitivity setting should be switched to the low-sensitivity setting before finally confirming the exact location of the power source.
[0003] The current leakage current circuit breaker tester's computer testing device is integrated with the test head. When testing the leakage current circuit breaker tester, the testing device needs to be placed in a proper position so that the leakage current circuit breaker tester can perform the test. At the same time, during use, if the device is not held securely, it is easy for the device to fall to the ground and damage the internal components. When the device is installed in a brightly lit environment, it is not convenient to observe its panel. Utility Model Content
[0004] The purpose of this invention is to provide a leakage current switch tester to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a leakage current switch tester, including a leakage current switch tester body, an auxiliary component installed on the outside of the leakage current switch tester body, a second protective cotton plate installed on the outside of the auxiliary component, a first protective cotton plate installed above the second protective cotton plate, a side rubber protective plate provided on the outer side of the auxiliary component, a shrink seat installed on the top of the leakage current switch tester body, and a shrink plate slidably connected inside the shrink seat.
[0006] Through the above technical solution: during the use of the leakage current switch tester, when the device is carried to the testing location, the first and second protective cotton plates can protect the device during use. If the device is not held securely and the front of the device falls, the first and second protective cotton plates will press and shrink against the ground to prevent the front of the device from directly contacting the ground.
[0007] Furthermore, the above technical solution also includes:
[0008] A light-shielding base is fixedly installed on the top of the shrink plate, and a fixing component is installed at the rear end of the main body of the leakage current switch tester.
[0009] Through the above technical solution: at the same time, the protective cotton plate installed can fit the outer wall of the device, and the side rubber protective plate on the outer side of the device protects the device when it comes into contact with the ground on the side. At the same time, when the device is observed in bright light, the shrink plate can slide out from inside the shrink seat, so that the light shield can block the light on the detection panel to facilitate observation.
[0010] The above technical solution further includes:
[0011] A fixing seat is installed below the fixing component, a base is fixedly installed inside the fixing seat, a fixing groove is opened above the base, an adhesive plate is slidably connected above the fixing groove, and an installation plate is installed above the adhesive plate.
[0012] The above technical solution involves installing an adhesive plate on the back of the base, then sliding the base into the fixing groove and locking it with the fixing seat. This allows the device to be attached to the wall, preventing the main body of the testing device from taking up too much space on the table and causing inconvenience during use.
[0013] In the above technical solution, the mounting plate has mounting holes on its side and ventilation holes are provided above the mounting holes.
[0014] The above technical solution involves a mounting hole that serves as a side-mounted interface for external data adjustment, forming the basic component of the device. Ventilation holes facilitate the dissipation of internal heat during use.
[0015] In the above technical solution, a connection end is provided below the vent hole, and an input port is installed at the rear end of the connection end.
[0016] The above technical solution involves: the connection end being the port where the test cable is fixed, which restricts the cable and prevents it from being pulled out; and the input port being the power supply component of the main body of the leakage current switch tester.
[0017] Furthermore, in the above technical solution, a fixing post is installed on the side of the input port.
[0018] The above technical solution involves using a fixing column as a side protective element of the main body of the leakage current switch tester, which is connected to the protective plate on its outer wall.
[0019] Furthermore, in the above technical solution, a support seat is installed on the side of the fixed column.
[0020] The above technical solution involves a support base, which forms the top structure of the leakage current switch tester. When the device is testing the switch, it can be laid down and supported by the support base.
[0021] The beneficial effects of this utility model are:
[0022] 1. In the process of using the leakage current switch tester, when the device is carried to the testing location, the first and second protective cotton plates can protect the device during use. If the device is not held securely and falls face down, the first and second protective cotton plates will press and shrink against the ground to prevent the front of the device from directly contacting the ground. At the same time, the protective cotton plates can fit against the outer wall of the device, and the side rubber protective plates on the outer side of the device will protect the device when it contacts the ground from the side. In addition, when observing the device in bright light, the shrink plate can slide out from inside the shrink base to block the light on the test panel, so as to facilitate observation.
[0023] 2. This utility model has a fixing base installed below the fixing component, and a base is fixedly installed inside the fixing base. A fixing groove is opened on the top of the base, and an adhesive plate is slidably connected above the fixing groove. An installation plate is installed above the adhesive plate. By installing the adhesive plate on the back of the base and then sliding the base into the fixing groove, it can be locked by the fixing base and can be stuck to the wall. This avoids the main body of the testing device occupying a large area of the table and causing inconvenience to use. Attached Figure Description

When the device is not held securely and the front of the device falls, the protective cotton plate 1 22 and the protective cotton plate 234 will press and shrink against the ground to prevent the front of the device from directly contacting the ground. The protective cotton plate can fit the outer wall of the device, and the side rubber protective plate 21 on the outer side of the device will protect the device when the side contacts the ground.
[0036] This embodiment provides a leakage current switch tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:
[0037] A light-shielding seat 25 is fixedly installed on the top of the shrink plate 26, and a fixing component 3 is installed at the rear end of the main body 1 of the leakage current switch tester.
[0038] When the device is used for observation in bright light, the shrink plate 26 can be slid out from inside the shrink base 27 so that its light shield 25 can block the light from the detection panel to facilitate observation.
[0039] This embodiment provides a leakage current switch tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a fixing base 31 is installed below the fixing component 3, a base 34 is fixedly installed inside the fixing base 31, a fixing groove 33 is opened above the base 34, an adhesive plate 32 is slidably connected above the fixing groove 33, and an mounting plate 12 is installed above the adhesive plate 32.
[0040] By installing the adhesive plate 32 on the back of the base and then sliding the base into the fixing groove 33, which is then locked by the fixing seat 31, it can be stuck to the wall, thus avoiding the main body of the test device occupying too much of the table surface and causing inconvenience to use.
[0041] This embodiment provides a leakage current switch tester, which, in addition to the technical solution of the above embodiment, also has the following technical features: a mounting hole 13 is installed on the side of the mounting plate 12, and a vent hole 11 is opened above the mounting hole 13.
[0042] Among them, the mounting hole 12 is the interface for adjusting the internal data of the device by connecting to the outside from the side, and it is the basic component of the device. The vent hole 11 is to facilitate the dissipation of internal heat when the device is in use.
[0043] This embodiment provides a leakage current switch tester, which, in addition to the technical solution of the above embodiment, also has the following technical features: a connection end 14 is provided below the vent 11, and an input port 15 is installed at the rear end of the connection end 14.

[0045] This embodiment provides a leakage current switch tester, which, in addition to the technical solution of the above embodiment, also has the following technical features: a fixing post 16 is installed on the side of the input port 15.
[0046] Among them, the fixing column 16 is the side protection element of the main body 1 of the leakage current switch tester, and it is connected to the protective plate on its outer wall.
[0047] This embodiment provides a leakage current switch tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a support base 18 is installed on the side of the fixing column 16.
[0048] Among them, the support base 18 is the top structure of the main body 1 of the leakage current switch tester. When the device tests the switch, the device can be laid down and supported by the support base 18.
[0049] Working Principle: During use, when the leakage current switch tester body 1 is carried to the testing location, the protective cotton plates 22 and 23 provide protection. If the device is not held securely and falls face-first, the protective cotton plates 22 and 23 compress and shrink upon contact with the ground, preventing direct contact between the device's front and the ground. The protective cotton plates fit snugly against the outer wall of the device, and the side rubber protective plates 21 on the outer side of the device protect it when the side contacts the ground.
[0050] When the device is being observed in bright light, the shrink plate 26 can be slid out from inside the shrink base 27 so that its light shield 25 can block the light from the detection panel to facilitate observation.
[0051] In the use of the device, by installing the adhesive plate 32 on the back of the base and then sliding the base into the fixing groove 33, it can be locked by the fixing seat 31, thus sticking it to the wall and avoiding the main body of the test device occupying too much of the table surface, which would cause inconvenience to use.
