Description

Technical Field

[0001] This utility model relates to the field of fuses, and specifically to a fuse resistance detection device. Background Technology

[0002] During the operation of electrical equipment, fuses, as important overcurrent protection devices, directly affect the safe and stable operation of the entire circuit system. Resistance is one of the key indicators for evaluating fuse performance, and accurately measuring fuse resistance is crucial for ensuring the normal operation of the circuit system.

[0003] Currently, the common method for testing fuse resistance is to use a multimeter to test each fuse individually. In practice, technicians hold the multimeter, connect the probes to the two terminals of the fuse, and read the resistance value to determine if the fuse is functioning correctly. If the resistance is infinite, the fuse is faulty and cannot conduct current; if the resistance is very low, the fuse is functioning normally. However, this traditional testing method has significant limitations. For testing a large number of fuses, this method is time-consuming, labor-intensive, and extremely inefficient. Therefore, there is an urgent need for a device that can quickly test fuse resistance. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solution: A fuse resistance testing device includes: a testing platform, a testing base, a display platform, and a lifting assembly. The testing platform is provided with positioning bases, and the testing base is positioned between the positioning bases. The testing base is provided with several sets of fuse placement slots spaced apart. The lifting assembly is located at the upper end of the testing platform. The display platform is lifted and lowered on the testing platform via the lifting assembly. Several sets of conductive contact groups are fixed at intervals at the lower end of the display platform. Each conductive contact group includes two contacts arranged front and rear, and the front and rear contacts correspond to the two terminals of one fuse core in each set of fuses. The display platform is provided with several sets of indicator lights. Each set of indicator lights forms a circuit by electrically connecting the two contacts of the corresponding set of conductive contact groups. Each circuit also includes an electrically connected resistor and a battery.

[0006] As a further improvement, the bottom of the display platform is provided with a plug rod, and the positioning seat is provided with a plug hole for matching the plug rod.

[0007] As a further improvement, the inner side of the positioning seat is provided with a notch groove for matching the detection seat.

[0018] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A fuse resistance testing device includes: a testing platform 1, a testing base 2, a display platform 3, and a lifting assembly 4. The testing platform 1 is provided with positioning bases 11, and the testing bases 2 are positioned between the positioning bases 11. The testing bases 2 are provided with a plurality of placement slots 21 for fuses 5 at intervals. The lifting assembly 4 is disposed on the upper end of the testing platform 1. The display platform 3 is lifted and lowered on the testing platform 1 by the lifting assembly 4. A plurality of conductive contact groups 31 are fixedly fixed at intervals on the lower end of the display platform 3. Each conductive contact group 31 includes two contacts 311 arranged in a front-to-back manner. The contacts 311 arranged in a front-to-back manner correspond to the two terminals 52 of one fuse core 51 in each fuse group. The display platform 3 is provided with a plurality of indicator lights 31. Each indicator light 31 forms a circuit by electrically connecting the two contacts 311 of the corresponding conductive contact group 31. Each circuit also includes an electrically connected resistor 33 and a battery 34.

[0021] like Figures 1-4 As shown, firstly, several fuses to be tested are placed in the placement slots of the test stand. The design of the test stand allows the fuses to be stably positioned, providing a foundation for subsequent testing. Next, the test stand containing the fuses is placed between the positioning seats of the test platform, completing the positioning and installation of the test stand. Subsequently, the display platform is moved downwards by controlling the lifting assembly. The cylinder in the lifting assembly pushes the support plate, causing the display platform to slide downwards along the guide post, so that the contacts in the conductive contact group at the lower end of the display platform make tight contact with the wiring terminals of the fuse core.

[0022] At this point, the indicator lights, resistors, and batteries on the display stand form a closed circuit with the conductive contact group. If the fuse resistance is normal, meaning it can conduct current normally, the circuit is complete, current flows in the circuit, and the indicator light will illuminate. If the fuse resistance is damaged, the circuit cannot conduct, no current flows, and the indicator light will not illuminate. By observing the on / off state of the indicator lights, one can intuitively determine whether the resistance of all fuses placed on the test stand is normal, achieving simultaneous detection of the resistance of multiple fuses.

[0023] This testing device significantly improves the efficiency of fuse resistance testing. Compared to the traditional method of testing each fuse individually with a multimeter, it eliminates the need for technicians to operate each fuse individually, allowing multiple fuses to be tested at once, saving considerable time and labor costs. Furthermore, the indicator lights visually display the test results, reducing the chances of missed detections or misjudgments caused by subjective judgment during manual testing. This effectively improves the accuracy and reliability of the test results, meeting the needs of rapid and accurate fuse testing in actual production and maintenance.

[0024] As a further preferred embodiment, the display platform 3 has a plug 36 at its bottom, and the positioning seat 11 has a matching socket 111 for the plug 36. When the display platform moves downward via the lifting assembly, the plug at the bottom of the display platform can be accurately inserted into the socket on the positioning seat, thereby further positioning and stabilizing the display platform. The matching design of the plug and socket restricts the horizontal movement of the display platform, ensuring that the contacts in the conductive contact group can accurately contact the terminals of the fuse core, thus guaranteeing the accuracy and stability of the circuit connection.

[0025] As a further preferred embodiment, the inner side of the positioning seat 11 is provided with a notch 112 that matches the detection seat 2. The shape of the notch matches the detection seat, so that when the detection seat is placed between the positioning seats, the edge of the detection seat can be embedded in the notch, achieving precise positioning of the detection seat. This design utilizes the cooperation of mechanical structures to limit the range of movement of the detection seat on the positioning seat, keeping it in a fixed position during the detection process.

[0026] As a further preferred embodiment, the placement slot 21 of the detection seat 2 is provided through at the front, while the rear side of the placement slot 21 does not extend to the rear end face of the detection seat 2. The through-slot design at the front facilitates the insertion of the fuse into the placement slot from the front, making the operation simple and convenient; while the design that the rear side does not extend to the rear end face of the detection seat provides a limiting support for the fuse after it is inserted into the placement slot, preventing the fuse from sliding out or shifting from the rear, and ensuring the stability of the fuse in the placement slot.

[0027] In a further preferred embodiment, the lifting assembly 4 includes a guide column 41 and a cylinder 42. Two sets of lifting assemblies 4 are symmetrically arranged. Support plates 35 are fixed to both ends of the display platform 3. The lower ends of the guide columns 41 and 42 are fixed to the detection platform 1, and the upper ends of the guide columns 41 are slidably disposed within the support plates 35. The piston rod of the cylinder 42 is connected to the outer side of the support plate 35. The two symmetrically arranged lifting assemblies are located at both ends of the display platform. The guide columns provide guidance for the vertical movement of the display platform, ensuring that the display platform can move smoothly along the vertical direction. The piston rod of the cylinder provides power for the lifting of the display platform by connecting to the support plates. When the cylinder operates, the extension and retraction of the piston rod drives the support plates, thereby causing the display platform to slide up and down along the guide columns, realizing the lifting movement of the display platform.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
