Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a modular expandable high-voltage connector, including a protective shell 1 to protect the internal structure.

A protection mechanism 2 is provided on the upper and lower sides of the protective shell 1. The protection mechanism 2 is used to protect the internal structure of the protective shell 1.

[0032] Specifically, the protective shell 1 provides all-around protection for the internal precision structure. A mounting sleeve 3 is fixed to the rear side of the inside of the protective shell 1, and an insulator 4 is fixedly connected to the rear side of the inside of the mounting sleeve 3. The insulator 4, with its excellent insulation performance, effectively prevents circuit interference and ensures stable operation of the connector.

[0033] Reference Figure 2 and Figure 5 The protective mechanism 2 includes multiple hinges 201. The rear sides of the multiple hinges 201 are fixedly connected to the upper and lower front sides of the protective shell 1. The multiple hinges 201 are fixedly connected to the adjacent sides of the protective plates 202. The protective plates 202 can be opened and closed through the hinges 201. The left and right front ends of the top protective plate 202 are fixedly connected to slide rails 203. The bottom front sides of the two slide rails 203 are slidably connected to sliding sleeves 204. The sliding sleeves 204 can slide on the slide rails 203. The left and right front ends of the bottom protective plate 202 are fixedly connected to support blocks 205. The top of the two support blocks 205 are fixedly connected to fixing rods 206. When the sliding sleeves 204 slide down, they will cover the fixing rods 206 on the top of the support blocks 205 to prevent the protective plate 202 from opening accidentally.

[0034] Specifically, the rear sides of adjacent hinges 201 are fixed to the upper and lower front ends of the protective shell 1, respectively. Protective plates 202 are connected between the hinges 201, allowing the protective plates 202 to open and close flexibly with the help of the hinges 201, providing additional protection for the inside of the connector. The left and right ends of the front side of the top protective plate 202 are each fixed with a slide rail 203. A sliding sleeve 204 is installed at the bottom front side of the two slide rails 203. The left and right ends of the front side of the bottom protective plate 202 are fixed with support blocks 205. A fixing rod 206 is connected to the top of each support block 205. When the sliding sleeve 204 slides down along the slide rail 203, it fits the fixing rod 206, thus forming a stable locking structure, effectively preventing the protective plate 202 from opening accidentally and ensuring the safety of the connector.

[0035] Reference Figure 1 and Figure 2 Multiple friction pads 11 are fixedly connected to the outer wall of the protective shell 1. Connecting rods 12 are fixedly connected between adjacent friction pads 11 to increase friction with the hand. Two diagonal braces 13 are fixedly connected to the bottom of the two support blocks 205. The bottom of the multiple diagonal braces 13 is fixedly connected to the bottom front side of the bottom support block 205 to increase the support of the support block 205. Top plates 14 are fixedly connected to the upper and lower sides of the two slide rails 203. The multiple top plates 14 are all rounded to prevent the sliding sleeve 204 from sliding out of the slide rail 203.

[0036] Specifically, multiple friction pads 11 are fixed to the outer wall of the protective shell 1. Adjacent friction pads 11 are connected by connecting rods 12, which increases the friction when in contact with the hand, making it easier to pick up and install the connector. The support block 205 on the front side of the bottom protective plate 202 has two diagonal braces 13 fixed to the bottom. The bottom of the multiple diagonal braces 13 is connected to the bottom front side of the bottom support block 205, which significantly enhances the support performance of the support block 205. On the upper and lower sides of the slide rail 203 of the top protective plate 202, there are rounded top plates 14, which effectively prevent the slide sleeve 204 from accidentally sliding out of the slide rail 203 and ensure the stable operation of the entire protective structure.

[0037] Reference Figure 3 , Figure 4 and Figure 5 The protective shell 1 has a semi-circular groove 15 on the front side. The rear sides of the two protective plates 202 are fixedly connected to sealing tubes 16 to prevent water from entering when the protective plates 202 are closed. The bottoms of multiple hinges 201 are fixedly connected to the upper and lower left and right ends of the protective shell 1 at equal intervals. The rear sides of multiple plugs 5 are fixedly connected to the front side of the insulator 4 at equal intervals. The sealing gasket 10 matches the groove 9. Multiple friction pads 11 are set at equal intervals.

[0038] Specifically, a semi-circular groove 15 is opened on the front side of the protective shell 1, which cooperates with the sealing tube 16 fixed on the rear side of the protective plate 202. When the protective plate 202 is closed, it can effectively prevent water from entering the interior and play a good waterproof sealing role. Multiple hinges 201 are evenly distributed at the bottom of the upper, lower and left and right ends of the protective shell 1 to ensure the stable opening and closing of the protective plate 202. Multiple plugs 5 are evenly fixed on the front side of the insulator 4 to ensure electrical connection. The sealing gasket 10 matches the groove 9 to further enhance the seal. Multiple friction pads 11 on the outer wall of the protective shell 1 are evenly arranged to improve the handheld operation experience.

[0039] Working principle: The protective shell 1 acts as an external protective barrier, providing all-round protection for the internal precision structure. The mounting sleeve 3 provides stable support for the insulator 4. The insulator 4 utilizes its excellent insulation properties to effectively isolate conductive parts at different potentials under high voltage conditions, preventing electromagnetic interference between circuits and ensuring stable current transmission along a predetermined path, thus guaranteeing stable connector operation. The plug 5 connects to the front of the insulator 4, responsible for establishing an electrical connection with external equipment, enabling the input and output of high-voltage power. The heat dissipation pipes 6 are evenly distributed around the inside of the protective shell 1. During operation, external cool air flows from the front of the heat dissipation pipes 6. The air flows in through the side inlet 7 and absorbs the heat generated by the current transmission during the flow through the internal structure. Then it flows out through the exhaust port 8 between the adjacent heat dissipation pipes 6, thereby efficiently carrying the heat out of the connector and maintaining the internal structure at a suitable temperature. This prevents performance degradation or component damage due to overheating. The sealing gasket 10 fixed in the front groove 9 inside the protective shell 1 fits against the external mating parts during the use of the connector, further improving the sealing performance and effectively blocking the intrusion of external impurities such as dust and moisture. This prevents short circuits or corrosion caused by the entry of impurities and ensures long-term reliable operation of the connector.

[0040] The protective plate 202 connected between the hinges 201 allows the protective plate 202 to tightly cover the inside of the connector under normal conditions, effectively resisting external interference factors such as collisions, dust, and moisture. When it is necessary to lock the protective plate 202, simply push the sliding sleeve 204 so that it slides smoothly down along the slide rail 203. As the sliding sleeve 204 moves down, it can accurately lock the fixing rod 206, and a stable locking state is formed between the top protective plate 202 and the bottom protective plate 202. Even if the equipment suffers accidental vibration, strong impact, or other complex working conditions that may cause the protective plate 202 to shake, this locking structure can effectively prevent the protective plate 202 from opening accidentally due to its stability, thus providing a reliable guarantee for the safe operation of the high-voltage connector.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
