Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage fuse processing, in particular to a low-voltage fuse testing device. Background Art

[0002] A low-voltage fuse is a common low-voltage electrical appliance. It is often used in power systems or electrical components to provide protection. When the current exceeds the specified value and after a certain period of time, the low-voltage fuse generates heat to cause one or several specially designed fuses to melt to achieve the function of disconnecting the circuit. When low-voltage fuses are produced and prepared, they often need to be tested for fusing performance before leaving the factory. However, there are still some defects in the actual operation of the low-voltage fuse test device.

[0003] Low-voltage fuse testing devices usually require staff to connect the power terminals at both ends of the low-voltage fuse product to the test power supply and introduce current into the product before completing the fuse test. This has the disadvantages of being difficult to test in batches and difficult to adjust the threshold current and voltage of the fuse test, thus affecting the test processing efficiency and causing inconvenience in operation. Utility Model Content

[0004] The purpose of the utility model is to provide a low-voltage fuse testing device to solve the problems raised in the above background technology.

[0006] Preferably, the voltage and current regulators are installed at equal intervals in sequence at the top of the cabinet, and the electric telescopic rod is installed inside the cabinet on one side of the voltage and current regulator. The voltage and current regulator and the electric telescopic rod are both provided with three, so that the electric telescopic rod can be used to conveniently control the automatic lifting and lowering movement of the adjustment seat.

[0007] Preferably, the connecting wire is installed between the voltage and current regulator and the conductive plug rod, the assembly buckle is arranged at the output end of the electric telescopic rod, and screws are evenly arranged between the assembly buckle and the adjustment seat to facilitate the disassembly and installation of the electric telescopic rod and the adjustment seat.

[0008] Preferably, assembly pins are evenly welded on the bottom of the positioning tool, and assembly slots matching the assembly pins are provided on the loading plate, so that the positioning tool can be independently disassembled, assembled and maintained.

[0009] Preferably, the electric slide rail is internally slidably connected with an electric slider, and a disassembly and installation structure is formed between the electric slider and the loading plate by screws, so that it is convenient to drive the loading plate to move forward and backward, which makes it easy to realize the automatic movement of the test piece to the processing area or leave the processing area, thereby facilitating loading and unloading operations.

[0010] Preferably, a threaded connecting column is welded between the power-carrying contact and the conductive slot, and a threaded connecting hole matching the threaded connecting column is provided on the adapter kit, so that the position of the power-carrying contact can be adjusted, which facilitates the power-carrying contact to contact and press the power-carrying terminal, which facilitates the subsequent auxiliary power-on test of the low-voltage fuse product.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The low-voltage fuse test device is installed with a voltage and current regulator and a low-voltage fuse product, so that the device optimizes its own performance. On the one hand, the electric telescopic rod on the test power supply mechanism is started to drive the corresponding adjustment seat to descend, so that the conductive rods at both ends of the adjustment seat are inserted into the conductive slot to complete the electrical connection between the voltage and current regulator and the low-voltage fuse product. In this way, the current and voltage preset in the voltage and current regulator are input into the low-voltage fuse product to achieve the test of the melting threshold of the low-voltage fuse product. If the low-voltage fuse product melts and burns at the threshold current and voltage, it means that the low-voltage fuse product is unqualified, otherwise it will be qualified. This enables the device to achieve automatic testing of the melting performance of the low-voltage fuse product. On the other hand, by arranging three groups of test mechanisms on the device, the device can achieve batch testing of products and improve work efficiency. In addition, the test power supply mechanism can be used to adjust the test voltage and current to optimize the melting test effect.

[0013] (2) The low-voltage fuse test device is equipped with threaded connection columns and energized contacts, etc., so that when the device is actually operated, on the one hand, the controller uses a preset program to start the electric slide rail to cooperate with the electric slider to drive the loading plate to move toward the inside of the cabinet, which is convenient for product loading and unloading operations and has strong practicality. On the other hand, the user can pre-install three low-voltage fuse products to be tested in the positioning tool to achieve fixed limit, and then the user installs the adapter kit on the energized terminals at both ends of the low-voltage fuse product, and then rotates the threaded connection column on the conductive slot to make the energized contact at the bottom contact and press the energized terminal, which is convenient for subsequent auxiliary implementation of the energized test of the low-voltage fuse product and improves the convenience of operation;

[0014] (3) The low-voltage fuse test device optimizes its own structure by installing an assembly clip and an adjustment seat. On the one hand, the user can use the plug-in connection structure composed of the assembly column and the assembly slot to realize independent disassembly, assembly and maintenance of the positioning tooling. On the other hand, the user can use the snap connection between the assembly clip and the adjustment seat and the locking and fixing effect of the matching screws to realize the disassembly and installation of the electric telescopic rod and the adjustment seat, which makes it easy to disassemble, maintain or replace the components of the device.
