[0002] In fields such as industrial automation, power transmission, and high-power electronic equipment, high-current strip probes are important connection components used to conduct high load currents. However, traditional high-current probes have many problems, such as the lack of effective short-circuit protection mechanisms, relying heavily on external fuses or circuit breakers, long response times, difficulty in accurately locating fault points, and the potential for equipment burnout or even fires when short circuits generate high temperatures; the mechanical structure is prone to wear, and the rigid contact design can cause contact point wear, increased resistance, and localized heating after long-term insertion and removal or vibration; reset and maintenance are difficult, with some probes with protection functions requiring manual reset or complete replacement, affecting equipment operating efficiency; and heat dissipation and insulation performance are poor, as the heat generated by high current is difficult to dissipate, and the insulating material is prone to aging and failure at high temperatures.

[0003] This utility model's high-current-resistant sheet probe, through its innovative fusible protection mechanism and mechanical linkage structure, can achieve rapid short-circuit disconnection, improving structural durability and ease of maintenance, and meeting the industrial demand for high safety and high reliability.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a high-current sheet probe with wear resistance, comprising a sheet probe and a fuse protection mechanism, wherein the sheet probe is fixedly connected to the fuse protection mechanism, and the fuse protection mechanism is used to drive the sheet probe to move upward and disconnect the connection when the sheet probe is short-circuited and generates high temperature;

[0006] The fuse protection mechanism includes a sleeve, and the sleeve contains a fuse assembly for moving the plate probe upward and disconnecting the connection.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1

[0024] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a high-current sheet probe that is resistant to loss.

[0025] Specifically, to solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-current sheet probe with wear resistance, including a sheet probe 100 and a fuse protection mechanism 200, wherein the sheet probe 100 is fixedly connected to the fuse protection mechanism 200, and the fuse protection mechanism 200 is used to drive the sheet probe 100 to move upward and disconnect the connection when the sheet probe 100 is short-circuited and generates high temperature;

[0026] The fuse protection mechanism 200 includes a sleeve 201, and the sleeve 201 is provided with a fuse assembly for moving the plate probe 100 upward and disconnecting the connection.

[0027] A through hole 1 is provided at the bottom axis of the sleeve 201, and a mounting base 206 is fixedly provided at the bottom axis of the sleeve 201. A through hole 2 is provided on the mounting base 206. The through hole 1 and the through hole 2 are coaxially distributed and are both longitudinally distributed.

[0028] A slide rod 204 is slidably provided inside the mounting base 206. The bottom of the slide rod 204 is fixedly connected to one end of the plate probe 100. A horizontal through groove 1 is provided on the outer side of the slide rod 204. A horizontal through groove 208 is provided on the mounting base 206. The first through groove and the second through groove 208 are coaxially distributed.

[0029] The fuse assembly includes a second sleeve 202 slidably disposed within the first sleeve 201. The first sleeve 201 and the second sleeve 202 respectively contain a first cavity and a second cavity, which are interconnected to form a movable cavity.

[0030] The movable cavity is provided with abutting components, which include abutting blocks 205 symmetrically fixed to the inner wall of the sleeve 202. The abutting blocks 205 are all wedge-shaped blocks with the distance between them gradually increasing from high to low.

[0031] The abutting component preferably includes an abutting rod 207 fixedly disposed in the through groove of the slide rod 204. There are two abutting rods 207, which are distributed opposite to each other, and the two ends of the two abutting rods 207 respectively abut against the inclined surfaces of the two abutting blocks 205.

[0032] The movable cavity is also provided with a fuse element, which includes a spring 209 fixedly disposed on the top of the slide rod 204, and a fuse block 203 fixedly disposed on the other end of the spring 209. The other end of the fuse block 203 is fixedly connected to the inner wall of the top end of the sleeve 202.

[0033] The high-current, loss-resistant sheet probe mainly consists of a sheet probe 100 and a fuse protection mechanism 200. During normal operation, the sheet probe 100 is in the connected state, allowing current to flow smoothly and meeting the requirements for high-current applications.

[0034] When the plate probe 100 experiences a short circuit, it generates high temperatures. At this time, the fuse block 203 in the fuse protection mechanism 200 melts under the influence of the high temperature. Since one end of the fuse block 203 is connected to the inner wall of the top of the sleeve 202, and the other end is connected to the top of the slide rod 204 through the spring 209, after the fuse block 203 melts, the tension of the spring 209 disappears, and the spring 209 begins to contract.

[0035] The slide rod 204 is installed inside the mounting base 206, which is fixed to the bottom axis of the sleeve 201. The through groove 1 on the outer side of the slide rod 204 is coaxially distributed with the through groove 208 on the mounting base 206, which provides guidance for the sliding of the slide rod 204. As the spring 209 contracts, the slide rod 204 slides upward within the mounting base 206.

[0036] A connecting rod 207 is fixed on the sliding rod 204. The two ends of the connecting rod 207 abut against the inclined surfaces of the connecting blocks 205 on the inner wall of the second sleeve 202. The connecting blocks 205 are wedge-shaped blocks, and the distance between them gradually increases from high to low. When the sliding rod 204 moves upward, the connecting rod 207 slides along the inclined surfaces of the connecting blocks 205, thereby pushing the second sleeve 202 to slide within the first sleeve 201.

[0037] Since the bottom of the slide bar 204 is fixedly connected to one end of the chip probe 100, the slide bar 204 moves upward, causing the chip probe 100 to move upward, which eventually disconnects the chip probe 100, thereby preventing the short circuit from worsening and protecting the entire circuit system.

[0038] In summary, this high-current-resistant, loss-resistant sheet probe conducts high current through the sheet probe 100, while the fuse protection mechanism 200 ensures circuit safety. In the fuse protection mechanism 200, sleeve 1 201 provides mounting space and support for other components; mounting base 206 is fixed at the bottom axis of sleeve 1 201, providing guidance for the sliding of slide rod 204; slide rod 204 slides within mounting base 206, its bottom connected to sheet probe 100; sleeve 202 slides within sleeve 1 201, and is linked to slide rod 204 via abutment block 205; when fuse block 203 melts at high temperature, spring 209 contracts, causing slide rod 204 to move upwards, ultimately disconnecting sheet probe 100, effectively preventing safety accidents caused by short circuits and ensuring stable operation of the circuit system.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
