Description

Technical Field

[0001] This utility model relates to the field of sensor testing equipment technology, and in particular to a high-temperature detection system for fuse current. Background Technology

[0002] Currently, products equipped with large-capacity battery packs are widely used. Furthermore, in some applications, such as battery packs for new energy vehicles, the high-temperature resistance requirements for fuses are extremely high. When high-temperature resistance is required for fuses, testing must also be conducted in a high-temperature environment to assess parameters such as the fuse's stability under high-temperature conditions.

[0003] However, high-temperature environments not only affect fuses but also test fixtures. Test fixtures need to be tested in high-temperature environments, and after testing, they need to be returned to room temperature. Only after cooling to a normal operating temperature can the fuses be removed and reinstalled, and then they are returned to the high-temperature environment. Therefore, test fixtures need to repeatedly switch between high-temperature and room-temperature environments, and their own temperature also fluctuates between high and low temperatures. Consequently, during long-term use, test fixtures are prone to thermal deformation, leading to lower durability. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature detection system for fuse current, thereby solving the technical problem of low durability of existing fuse test fixtures under high-temperature testing environments.

[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] This utility model embodiment provides a high-temperature detection system for fuse current, such as... Figure 1 and Figure 2 As shown, it includes: The base 100 has a support assembly 110 on it, which is used to receive the fuse 400. The crimping assembly 200 includes a support frame fixedly mounted on the base 100. The support frame includes two support plates 210 perpendicular to the base 100. The bottom of the support plates 210 is connected to the base 100. The front end of the bottom of the support plates 210 extends toward the support assembly 110 to form a transverse support portion 211. The transverse support portion 211 is provided with mounting holes. The rear end of the lower part of the support plate 210 is provided with a clearance groove 212. A mounting connection portion 213 is formed below the clearance groove 212. The mounting connection portion 213 is provided with mounting holes. The crimping assembly 200 also includes a crimp connector 220, which is movably connected to the support frame. The test assembly 300 includes a test connector 310 for electrical connection with the communication port 410 of the fuse 400.

[0027] In this embodiment, the fuse 400 also includes a current sensor, a communication port 410, and a circuit board, forming an intelligent fuse or electronic fuse system. It can use the current sensor to detect the current in real time and accurately, use the control unit of the circuit board to analyze and judge the data, and use the semiconductor switch and other structures of the circuit board to achieve rapid melting. It combines the advantages of the sensor's speed and accuracy with the repeatable action of the semiconductor switch, and can achieve rapid power-off at the microsecond or even nanosecond level. It is particularly suitable for protecting advanced equipment that is very sensitive to overcurrent, such as power components and battery packs of electric vehicles.

[0028] in, Figure 1 This is one of the overall structural schematic diagrams of a high-temperature detection system for fuse current provided in an embodiment of this utility model. Figure 2 This is the second schematic diagram of the overall structure of the high-temperature detection system for fuse current provided in this embodiment of the utility model. Figure 1 and Figure 2 The test fixture was observed from both the front and rear three-dimensional perspectives.

[0029] The support structure in the crimping assembly 200 is a part of the test fixture that is prone to thermal deformation. This invention provides a transverse support part 211 and a clearance groove 212 on the support plate 210, so that the mounting holes are exposed from the transverse support part 211 and the clearance groove 212 respectively. In this way, the mounting parts can be operated through the mounting holes. Thus, when the support plate 210 undergoes thermal deformation, the mounting structure of the support plate 210 and the base 100 can be easily adjusted to solve the problem of thermal deformation that occurs during long-term use.

[0030] In some embodiments, the height of the clearance groove 212 is not less than 5 cm to provide sufficient operating space for easy operation of the mounting component.

[0031] Specifically, in some embodiments, the support plate 210 and the base 100 are fixed together by bolts. The bolts screw into the mounting connection portion 213 from the base 100 and partially protrude from the clearance groove 212. The support plate 210 and the base 100 are fixed together by bolts. The bolts screw into the transverse support portion 211 from the base 100 and partially protrude from the upper surface of the transverse support portion 211. In this case, when the bolts or the support plate 210 are deformed, the bolts can be manipulated from above the clearance groove 212 and the transverse support portion 211. For example, the bolts can be rotated, cut off, or welded to assist in their removal. Glue can also be applied to the mounting holes to improve the stability of the connection.

[0032] Figure 1 and Figure 2 Specific connectors are not shown, but obviously, in addition to bolted connectors, other connection methods such as riveting are also applicable.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, the crimping assembly 200 also includes a crimping drive mechanism, which includes a crimping mounting plate 230. Both ends of the crimping mounting plate 230 are respectively connected to the upper parts of two support plates 210. The upper part of the support plate 210 is provided with a clearance hole 214. The crimping mounting plate 230 and the support plate 210 are fixed together by bolts. The bolts are screwed from the crimping mounting plate 230 toward the support plate 210 and partially exposed in the clearance hole 214.

[0034] The structural design of the clearance hole 214 also facilitates the adjustment of the press-fit mounting plate 230. When high-temperature deformation affects the press-fit mounting plate 230, bolts, and support plate 210, the bolts can be easily operated through the clearance hole 214. Figure 1 and Figure 2 Specific connectors are not shown, but obviously, in addition to bolted connectors, other connection methods such as riveting are also applicable.

[0035] like Figure 2 As shown, the press-fit mounting plate 230 has a relatively long dimension, and the support plate 210 includes two clearance holes 214. Each clearance hole 214 can be designed to be a small size to meet the installation requirements of the press-fit mounting plate 230, avoid the clearance hole 214 being too large and affecting the structural strength of the support plate 210, and ensure the structural stability of the support plate 210.

[0036] In some embodiments, such as Figure 1 As shown, the crimping assembly 200 also includes a crimping handle 240. The crimping handle 240 is made of high-temperature resistant glass fiber material. This material allows the crimping handle 240 to have a lower surface temperature, especially when returning from a high-temperature testing environment to a normal temperature environment. The crimping handle 240 can reach a temperature that is easy to operate in a relatively short time, which can improve testing efficiency.

[0037] like Figure 1As shown, in some embodiments, the test assembly 300 further includes a movable test connector 320. A test connector 310 is disposed on a test limiting plate 330, which has an oval connecting hole 331. The test limiting plate 330 is mounted to the test connector 320 through the oval connecting hole 331. The test connector 320 moves towards or away from the support assembly 110, thereby allowing the test connector 310 to connect to or be removed from the communication port 410 of the fuse 400. The oval connecting hole 331 of the test limiting plate 330 facilitates adjustment of its left and right position, whereas the test connector 320 requires a guide rail or other guiding mechanism, making it less convenient to adjust its installation position. By adjusting the position of the test limit plate 330, the position of the test connector 310 can be adjusted, thereby offsetting the influence of thermal deformation on the test limit plate 330 and other structures, ensuring that the test connector 310 and the communication port 410 can always maintain accurate alignment, and avoiding damage to the communication port 410 of the probe fuse 400 of the test connector 310.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, the crimp connector 220 is provided with a heat shield 250, which is used to cover the PCB board portion of the fuse 400. Wherein, Figure 3 This is one of the partial structural schematic diagrams of the crimping assembly 200 in a high-temperature detection system for fuse current provided by an embodiment of this utility model. Figure 4 This is the second partial structural schematic diagram of the crimping assembly 200 in a high-temperature detection system for fuse current provided in this embodiment of the present invention. Figure 3 The circuit breaker 400 is shown in the figure. Figure 4 The fuse 400 is concealed. In high-temperature environments, the heat shield 250 covers the PCB portion of the fuse 400, which can prevent the high-temperature environment from affecting the PCB board, avoid temperature drift, and ensure the accuracy of test results.

[0039] Specifically, the heat shield 250 can adopt a contoured shape, such as... Figure 4 As shown, the communication port 410 is exposed while completely covering the PCB board.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
