It can be seen that existing connectors do not adequately protect the connector ports when not in use, do not assist in securing the connecting wires during wiring, and cannot properly secure multiple connectors together, significantly reducing efficiency. Summary of the Invention

[0004] In view of the technical problems existing in the prior art, the purpose of this invention is to provide a high-voltage, high-current shielded connector, which solves the problems that existing connectors cannot effectively protect the connection port when not in use, cannot assist in fixing the connection wire during wiring, and cannot be well fixed together when multiple connectors are used in combination, which greatly reduces the efficiency of use.

[0005] The auxiliary hole can help fix the connector, and the connecting post is placed in the auxiliary hole. When fixing through the auxiliary hole, the sliding plate will naturally move through the connecting post, which is convenient for transmission. The setting of the plug plate and the connecting cover allows the connectors to be combined and used one by one, which is convenient for blocking multiple connectors as needed. The first connecting block on the connecting cover, the second connecting block on the plug plate, and the slot are all fixed during assembly, making assembly and installation convenient.

The vertical plate and the push plate coincide in the vertical projection direction. A sliding groove is provided on the sliding frame, and a limit rod is fixedly installed in the sliding groove. A first support rod is slidably installed on the limit rod. The first support rod is fixedly connected to the connector body. Compression springs are fixedly installed in the sliding groove to ensure the stable movement of the sliding frame. The compression springs can provide a certain support force.

A fixing plate 35 is fixedly installed on the second fixing block 34. A support mechanism is slidably installed on the fixing plate 35. The base plate 1 can be installed in a suitable position through the mounting hole 2. After installation, it is fixed by auxiliary hole 3.

[0031] Reference Figure 2 The sectional view shows the positional relationship between the auxiliary hole 3 and the connecting post 7.

[0032] Reference Figure 3 Each of the two sliding frames 15 has a sliding groove 16, and each of the two sliding grooves 16 has a limit rod 17 fixedly installed in it. Each of the two limit rods 17 has a first support rod 18 slidably installed on it. Each of the two first support rods 18 is fixedly connected to the connector body 8. Each of the two sliding grooves 16 has a compression spring 19 fixedly installed in it, which ensures the stable movement of the two sliding frames 15 and allows the two sliding frames 15 to be smoothly reset when there is no pushing force.

[0033] Reference Figure 4 The support mechanism includes a second support rod 38 and a support plate 39. The second support rod 38 is slidably mounted on a fixed plate 35, and the support plate 39 is fixedly mounted on the second support rod 38.

The second support rod 38 is fixedly mounted on the slider 37, and a spring 40 is fixedly mounted in the groove 36. This ensures the stable movement of the support plate 39 and gives the support plate 39 a certain thrust, which plays a certain buffering role and prevents the support device from being crushed by the bracket.

[0034] Reference Figure 5 The fixing device includes a side plate 10 and several clamping plates 11. The side plate 10 is slidably mounted on the connector body 8, and the clamping plates 11 are all fixedly mounted on the top of the side plate 10. The driving mechanism includes a mounting block 12, a screw 13 and a knob 14. The mounting block 12 is fixedly mounted on the connector body 8, the screw 13 is rotatably mounted on the mounting block 12, and the knob 14 is fixedly mounted on the top of the screw 13. The screw 13 is threadedly connected to the side plate 10, so that rotating the screw 13 can drive the side plate 10 to move, and the side plate 10 can drive the clamping plates 11 to move to fix the connecting wire.

[0035] Reference Figure 6 The blocking mechanism includes a clamping plate 26, a second sliding hole 25 is opened on the connecting cover 23, the clamping plate 26 is slidably installed in the second sliding hole 25, a baffle 27 is fixedly installed on the top of the clamping plate 26, and a tension spring 28 is fixedly installed on the bottom of the baffle 27. The tension spring 28 is fixedly connected to the connecting cover 23, ensuring the stable movement of the clamping plate 26, and allowing the clamping plate 26 to smoothly reset when there is no tension after movement, thus ensuring the stability of the clamping plate 26.

[0036] In this embodiment, when using the device, the corresponding plug plate 29 is inserted into the connecting cover 23 on another corresponding connector body 8 according to the number of connector bodies 8 to be used. When the plug plate 29 is inserted into the connecting cover 23, the baffle 27 pulls the locking plate 26 to move. After the plug plate 29 is fully inserted into the connecting cover 23, the baffle 27 is released. Under the elastic force of the tension spring 28, the locking plate 26 can be smoothly reset and inserted into the connecting groove 30 on the corresponding plug plate 29, thus achieving initial fixation. The assembled connector body 8 is installed and fixed through the mounting hole 2. After installation, it is reinforced through the auxiliary hole 3. During reinforcement, the connecting post 7 is pushed upward, the connecting post 7 drives the sliding plate 5 to move, the sliding plate 5 drives the second fixing block 34 to move, and the second fixing block 34... 4. The fixed plate 35 moves, which in turn moves the support plate 39. The support plate 39 presses against the corresponding insert plate 29 for auxiliary fixation. At the same time, the slide plate 5 moves the two first fixed blocks 32, which in turn moves the two push plates 33. The two push plates 33 move the two sliding frames 15, which in turn moves the top plate 20. The top plate 20 moves several fixed rods 21, which in turn moves several protective plates 22. This allows the wiring port 9 to be exposed for wiring. After the connecting wire is connected, the screw 13 can be rotated. The screw 13 moves the side plate 10, which in turn moves several clamping plates 11. The clamping plates 11 and the protective plates 22 work together to fix the connecting wire, making it convenient to use.

[0037] Example 2

[0038] The difference between this embodiment and embodiment one is that an indicator light can be added to the connector body 8 to indicate the connection status, and a protective cover can be added to the connector body 8 to prevent oil leakage and dripping onto the connector body 8 during connection.
