DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-6 As shown, the anti-breakage insulating terminal provided in this embodiment includes a sliding disk metal sheet 1 and an elastic contact 2. The sliding disk metal sheet 1 includes a sliding disk sheet 3, a sliding disk sheet 4 and a sliding disk sheet 5. The sliding disk sheet 3, the sliding disk sheet 4 and the sliding disk sheet 5 are circular rings, and the sliding disk sheet 3, the sliding disk sheet 4 and the sliding disk sheet 5 are concentric. A plurality of elastic contacts 2 are respectively connected to one end surface of the sliding disk sheet 3, the sliding disk sheet 4 and the sliding disk sheet 5. The other end surface of the sliding disk metal sheet 1 is fixedly connected to a right wiring metal sheet 6. The end of the plurality of elastic contacts 2 away from the sliding disk metal sheet 1 is fixedly connected to a metal interlayer 7. The metal interlayer 7 A left wiring metal sheet 8 is fixedly connected to the side away from the elastic contact 2. The connectors of a multi-strand cable are respectively welded to multiple left wiring metal sheets 8, and the connectors of another multi-strand cable are respectively welded to the right wiring metal sheet 6. The left connector is connected to the metal contact through the left wiring metal sheet 8 and the metal interlayer 7, and the right connector is connected to the sliding disk metal sheet 1 through the right wiring metal sheet 6. The sliding disk metal sheet 1 is a concentric circle structure, and multiple elastic contacts 2 are in contact with the sliding disk metal sheet 1. When the left or right line is twisted, the multiple elastic contacts 2 rotate around the center of the sliding disk metal sheet 1, so that the line no longer twists, thereby preventing the line joint from loosening due to line distortion.

[0025] Further, such as Figure 6 As shown, a spring 9 is provided between the elastic contact 2 and the metal interlayer 7. One end of the spring 9 is fixedly connected to the elastic contact 2, and the other end of the spring 9 contacts the surface of the metal interlayer 7. The elasticity of the elastic contact 2 itself makes the elastic contact 2 contact with the sliding disk metal sheet 1. The spring 9 applies pressure between the metal interlayer 7 and the elastic contact 2 to make the elastic contact 2 and the sliding disk metal sheet 1 contact more closely, thereby preventing poor contact from occurring.

[0026] Furthermore, Figure 6 As shown, the sliding disk metal sheet 1 and the elastic contact 2 are both made of silver alloy, which makes the sliding disk metal sheet 1 and the elastic contact 2 more durable.

[0027] Among them, such as Figure 4 As shown, the side of the sliding disk metal sheet 1 is fixedly connected to the right shell 10, and the sliding disk metal sheet 1 is embedded in the surface of one end of the right shell 10. The right shell 10 is made of high-temperature resistant insulating plastic. The sliding disk sheet No. 1 3, the sliding disk sheet No. 2 4 and the sliding disk sheet No. 3 5 are made of high-temperature resistant insulating plastic to prevent discharge and short circuit in adjacent circuits.

[0028] Among them, such as Figure 2 as well as Figure 4 As shown, the outer surface of the right shell 10 is fixedly connected to the bearing 11, the outer ring of the bearing 11 is fixedly connected to the left shell 12, the metal interlayer 7 is embedded in the bottom surface of the left shell 12 and is fixedly connected to the left shell 12, the left shell 12 and the right shell 10 are connected through the bearing 11, and the left shell 12 and the right shell 10 rotate relative to each other.

[0029] Among them, such as Figure 1 as well as Figure 6 As shown, the left shell 12 and the right shell 10 are fixedly connected with a sealing cover 13, and a wire hole 14 is provided at the end of the sealing cover 13 away from the bearing 11. A sealing ring 15 is provided in the wire hole 14, and the sealing ring 15 is made of insulating rubber. A glue injection hole 16 is provided near the wire hole 14 of the sealing cover 13. The cables at both ends pass through the two wire holes 14 respectively and are then welded to the left wiring metal sheet 8 and the right wiring metal sheet 6. Then the sealing cover 13 is fixedly connected to the left shell 12 and the right shell 10, and finally insulating sealant is injected from the glue injection hole 16.

[0030] Among them, such as Figure 6As shown, the left wiring metal sheet 8 includes a left metal sheet No. 1 801, a left metal sheet No. 2 802 and a left metal sheet No. 3 803, and the right wiring metal sheet 6 includes a right metal sheet No. 1 601, a right metal sheet No. 2 602 and a right metal sheet No. 3 603. The left metal sheet No. 1 801 is connected to the right metal sheet No. 1 601 through the sliding disk No. 1 3, the left metal sheet No. 2 802 is connected to the right metal sheet No. 2 602 through the sliding disk No. 2 4, and the left metal sheet No. 3 803 is connected to the right metal sheet No. 3 603 through the sliding disk No. 3 5. The corresponding metal sheets need to be connected when wiring.

[0031] like Figures 1-6 As shown, the principle of the anti-breakage insulating terminal provided in this embodiment is as follows: the cables at both ends pass through the two wire holes 14 respectively, the connectors of one multi-strand cable are respectively welded to the multiple left wiring metal sheets 8, and the connectors of the other multi-strand cable are respectively welded to the right wiring metal sheets 6, and then the sealing cover 13 is fixedly connected to the left shell 12 and the right shell 10, and finally, the insulating sealant is injected from the injection hole 16. After the insulating sealant solidifies, the left shell 12 and the right shell 10 are connected through the bearing 11, so that the left shell 12 and the right shell 10 rotate relative to each other, and the sliding disk metal sheet 1 is embedded in the surface of one end of the right shell 10. The body 10 is made of high-temperature resistant insulating plastic, so the No. 1 sliding disk 3, the No. 2 sliding disk 4 and the No. 3 sliding disk 5 are made of high-temperature resistant insulating plastic to prevent discharge in adjacent circuits from causing short circuits. The elasticity of the elastic contact 2 itself makes the elastic contact 2 contact with the sliding disk metal sheet 1. The spring 9 applies pressure between the metal interlayer 7 and the elastic contact 2 to make the elastic contact 2 and the sliding disk metal sheet 1 contact more closely, preventing poor contact from occurring. When the line on the left or right side is twisted, multiple elastic contacts 2 rotate around the center of the sliding disk metal sheet 1, so that the line is no longer twisted, preventing the line joint from loosening due to line distortion.
