Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, and in particular to a protective device for high-voltage connectors. Background Technology

[0002] With the vigorous promotion and application of new energy vehicles, the usage scenarios of these vehicles are becoming increasingly diverse. During long-term use, high-voltage connectors, due to prolonged exposure, are prone to problems such as being covered in mud and sand, which seriously affects connector maintenance and overall vehicle safety. Specifically, as a key component for power transmission in new energy vehicles, high-voltage connectors must be safe and reliable during use. However, the connector ends of existing new energy commercial vehicles are almost exposed at the bottom of the vehicle frame without any safety protection measures. This leads to phenomena such as mud and sand accumulation and even aging of high-voltage connectors after a certain period of use. As a result, the connectors become difficult to plug and unplug, and long-term use accelerates the corrosion of the plating on the connector body. In severe cases, it can even lead to insulation failure inside the connector.

[0003] For example, a high-voltage connector protection device disclosed in Chinese patent literature (publication number: CN218783280U) reduces the impact of external mud and dust on the high-voltage connector by setting a simple protective device, while also reducing the corrosion from external water sources (rainwater, muddy water) and other factors, thereby improving the service life of the connector and reducing safety hazards caused by insulation and corrosion. At the same time, the protective cover and the housing are easy to install and disassemble, which is conducive to the later maintenance and replacement of the connector. The cover adopts a corrugated cylinder structure design, which is convenient to operate. The cover, the high-voltage connector, and the equipment mounting panel can all be easily sealed and disassembled. The overall protective device is also applicable to similar multi-core connectors, elbow connectors, or low-voltage connectors.

[0004] However, before plugging or unplugging the high-voltage connector, the cover and the limiting ring are fixed by the second ring elastic cable tie. The cable tie needs to be inserted into the recessed area to lock it. When disassembling or assembling, the connecting short strap needs to be pulled manually to make the cable tie deform elastically and then detach from the recess. However, the high-voltage connectors of new energy commercial vehicles are mostly located in narrow spaces such as the bottom of the frame and the side of the chassis. Workers need to bend over or crawl to operate, which limits their range of hand movement. It is difficult to apply force accurately when pulling the connecting short strap, resulting in a cumbersome disassembly and assembly process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of disassembling and assembling the protective cover used for high-voltage connectors, which leads to cumbersome operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A protective device for a high-voltage connector includes a panel body, and a convenient disassembly and assembly mechanism is provided on the top of the panel body. The convenient disassembly and assembly mechanism includes an annular mounting block. The lower end of the annular mounting block is fixedly connected to the upper end of the panel body. The outer side of the annular mounting block is provided with symmetrically distributed guide grooves. An arc-shaped guide slider is slidably connected to the inner wall of the guide groove. A first return spring is fixedly connected to the upper end of the arc-shaped guide slider. One end of the first return spring is fixedly connected to the inner top wall of the guide groove. A gripping ring is fixedly connected to the outer side of each of the two arc-shaped guide sliders. A protective mechanism is provided on the top of the panel body.

[0007] Preferably, the inner wall of the gripping ring is slidably sleeved with the outer side of the annular mounting block, the upper end of the gripping ring is fixedly connected with an annular inclined block, and the outer side of the annular mounting block is provided with symmetrically distributed locking holes.

[0008] Preferably, the inner side of the annular mounting block has symmetrically distributed slots, and inserts are slidably inserted into the inner wall of the slots. Each of the two inserts has a connecting ring fixedly connected to one end opposite to the other, and the outer side of the connecting ring is movably sleeved with the inner wall of the annular mounting block.

[0009] Preferably, the inner side of the connecting ring is fixedly connected with symmetrically distributed mounting sleeves, and the inner wall of the mounting sleeve is slidably fitted with a round-headed locking block. One end of the round-headed locking block extends through to the outer side of the connecting ring and is movably engaged with the inner wall of the locking hole.

[0010] Preferably, a second return spring is fixedly connected to the other end of the round-headed locking block, and one end of the second return spring is fixedly connected to the inner wall of one side of the mounting sleeve.

[0011] Preferably, the protective mechanism includes a corrugated telescopic protective cover, the lower end of which is fixedly connected to the upper end of the connecting ring, a fixing ring fixedly connected to the upper end of the corrugated telescopic protective cover, a high-voltage connector body fixedly installed on the inner wall of the fixing ring, and a fixing plate fixedly connected to the upper end of the panel body.

[0012] Preferably, a high-voltage socket body is fixedly installed on the upper end of the fixing plate, the upper inner wall of the high-voltage socket body is movably inserted into the lower end of the high-voltage connector body, the lower end of the high-voltage socket body passes through the fixing plate and extends to the bottom of the panel body, and a device end socket is fixedly installed on the lower end of the high-voltage socket body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a convenient disassembly and assembly mechanism composed of annular inclined blocks and round-headed locking blocks allows workers to quickly release the connection between the connecting ring and the annular mounting block simply by lifting the gripping ring and using the annular inclined blocks to press the round-headed locking blocks. This eliminates the need for complex operations and greatly improves the efficiency of plugging and unplugging the high-voltage connector body. It is especially suitable for the operation requirements of narrow spaces such as the chassis of new energy commercial vehicles. The guiding cooperation between the insert and the slot ensures that the connecting ring is accurately inserted into the annular mounting block, greatly simplifying the operation steps and improving the efficiency of disassembly and assembly.

[0014] The corrugated telescopic protective cover is stably locked by the round-headed locking block under the action of the second return spring, effectively resisting the bumps and vibrations during vehicle operation and preventing the protective device from loosening. In terms of protective performance, the corrugated telescopic protective cover can be flexibly extended and retracted to tightly wrap the high-voltage connector, blocking the intrusion of mud, sand, rainwater, etc. It is also made of durable material and can cope with complex working conditions. In addition, the setting of the first and second return springs allows the components to automatically reset after operation, simplifying subsequent operations. The overall structural design takes into account convenience, stability and protection, ensuring the long-term safe and reliable operation of the high-voltage connector body.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Example like Figures 1-5 As shown, this utility model provides a technical solution: a protective device for a high-voltage connector, including a panel body 1, with a convenient disassembly and assembly mechanism provided on the top of the panel body 1. The convenient disassembly and assembly mechanism includes an annular mounting block 2, the lower end of which is fixedly connected to the upper end of the panel body 1, providing a stable mounting base for the entire convenient disassembly and assembly mechanism.

[0022] Symmetrically distributed guide grooves 21 are provided on the outer side of the annular mounting block 2. An arc-shaped guide slider 22 is slidably connected to the inner wall of the guide groove 21. The arc-shaped guide slider 22 can slide stably along the guide groove 21, playing the role of guiding and limiting.

[0023] A first return spring 23 is fixedly connected to the upper end of the arc-shaped guide slider 22. One end of the first return spring 23 is fixedly connected to the inner top wall of the guide groove 21. When the arc-shaped guide slider 22 moves upward, the first return spring 23 will be compressed. After the external force disappears, the elastic force of the first return spring 23 can drive the arc-shaped guide slider 22 to return to its original position.

[0024] A gripping ring 24 is fixedly connected to the outer side of each of the two arc-shaped guide sliders 22. The operator can apply force through the gripping ring 24 to drive the arc-shaped guide slider 22 to move. The inner wall of the gripping ring 24 is slidably sleeved with the outer side of the annular mounting block 2 to ensure the smooth movement of the gripping ring 24.

[0025] An annular inclined block 25 is fixedly connected to the upper end of the gripping ring 24. The outer side of the annular mounting block 2 has symmetrically distributed locking holes 26. When the annular inclined block 25 rises, it can use the inclined surface to press the round head locking block 211, causing it to disengage from the locking hole 26.

[0026] A symmetrically distributed slot 27 is provided on the inner side of the annular mounting block 2. A strip 28 is slidably inserted into the inner wall of the slot 27. The cooperation between the strip 28 and the slot 27 provides guidance for the insertion of the connecting ring 29, ensuring that the connecting ring 29 is accurately inserted into the annular mounting block 2.

[0027] Each of the two inserts 28 has a connecting ring 29 fixedly connected to one end. The outer side of the connecting ring 29 is movably sleeved with the inner wall of the annular mounting block 2. A symmetrically distributed mounting sleeve 210 is fixedly connected to the inner side of the connecting ring 29. A round-headed locking block 211 is slidably sleeved on the inner wall of the mounting sleeve 210. One end of the round-headed locking block 211 extends through to the outer side of the connecting ring 29 and is movably locked with the inner wall of the locking hole 26. The connection between the round-headed locking block 211 and the locking hole 26 can be used to fix the connecting ring 29 and the annular mounting block 2.

[0028] The other end of the round-headed locking block 211 is fixedly connected to a second return spring 212. One end of the second return spring 212 is fixedly connected to the inner wall of one side of the mounting sleeve 210. When the round-headed locking block 211 is squeezed, the second return spring 212 will be compressed. After the external force disappears, the elastic force of the second return spring 212 can push the round-headed locking block 211 to reset and lock into the locking hole 26.

[0029] A protective mechanism is provided above the panel body 1. The protective mechanism includes a corrugated telescopic protective cover 3. The lower end of the corrugated telescopic protective cover 3 is fixedly connected to the upper end of the connecting ring 29, and can be unfolded or retracted as the connecting ring 29 is disassembled or assembled.

[0030] A fixing ring 31 is fixedly connected to the upper end of the corrugated telescopic protective cover 3. A high-voltage connector body 32 is fixedly installed on the inner wall of the fixing ring 31 for fixing the high-voltage connector body 32.

[0031] A fixing plate 33 is fixedly connected to the upper end of the panel body 1. A high-voltage socket body 34 is fixedly installed on the upper end of the fixing plate 33. The upper inner wall of the high-voltage socket body 34 is movably inserted into the lower end of the high-voltage connector body 32 to realize the electrical connection between the high-voltage connector body 32 and the high-voltage socket body 34.

[0032] The lower end of the high-voltage socket body 34 passes through the fixing plate 33 and extends to the bottom of the panel body 1. The lower end of the high-voltage socket body 34 is fixedly installed with an equipment end socket 35 for connection with the equipment end.

[0033] With the above structural design, the protective device can quickly complete the protective installation of the high-voltage connector during use, and is easy to install and remove. At the same time, it can effectively block the invasion of mud, sand, rainwater and other substances into the high-voltage connector, ensuring the long-term safe and reliable operation of the high-voltage connector. It is especially suitable for scenarios such as new energy commercial vehicles.

[0034] The working process of this utility model: Step one: First, perform the initial connection of the high-voltage connector body 32. Precisely insert the lower end of the high-voltage connector body 32 into the upper end of the high-voltage socket body 34 to complete the electrical connection, laying the foundation for subsequent installation of the protective device. Next, install the protective mechanism. The worker holds the connecting ring 29 and aligns the inserts 28 on both sides of the connecting ring 29 with the symmetrically distributed slots 27 on the inner side of the annular mounting block 2. Insert the connecting ring 29 along the direction of the slots 27. During insertion, the connecting ring 29 drives the round-headed locking block 211 to move. The round end of the round-headed locking block 211 is squeezed by the inner wall of the annular mounting block 2, causing the round... The head locking block 211 moves into the mounting sleeve 210, while compressing the second return spring 212. When the connecting ring 29 is fully inserted into the annular mounting block 2, the round head locking block 211 reaches the locking hole 26. At this time, the elastic force of the second return spring 212 is released, pushing the round head locking block 211 to move outward. One end of the round head locking block 211 is precisely inserted into the corresponding locking hole 26, realizing the locking and fixing of the connecting ring 29 and the annular mounting block 2, thereby completing the fixing of the lower end of the corrugated telescopic protective cover 3. The corrugated telescopic protective cover 3 can form a protective enclosure for the high voltage connector body 32, blocking external mud, rainwater and other intrusions. Step two: When it is necessary to remove the high-voltage connector body 32 for maintenance or repair, first operate the convenient disassembly and assembly mechanism. The operator holds the grip ring 24 and pulls it upward. The grip ring 24 drives the annular inclined block 25 to rise synchronously. At the same time, the grip ring 24 slides in the guide groove 21 through the arc-shaped guide slider 22, causing the first return spring 23 to be compressed and contract. As the annular inclined block 25 rises, its inclined surface continuously compresses the round end of the round head block 211, forcing the round head block 211 to move into the mounting sleeve 210, compressing the second return spring 212. The round-headed locking block 211 gradually disengages from the locking hole 26. Then, the operator lifts the connecting ring 29, which drives the insert 28 to be pulled out of the slot 27, thereby disengaging the connecting ring 29 from the annular mounting block 2. After releasing the gripping ring 24, the elastic force of the first return spring 23 is released, causing the gripping ring 24, the annular inclined block 25, and the arc-shaped guide slider 22 to return to their initial positions. Finally, the high-voltage connector body 32 is removed from the high-voltage socket body 34, completing the disassembly operation of the high-voltage connector body 32 for subsequent maintenance and other work.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
