[0021] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0022] Example

[0023] According to the utility model, a safety protection and switch control structure of a rotary contact power supply with a fool-proof design is provided, including: Figure 1As shown, it includes contact 1, pad 2, upper part 3, lower part 4, foolproof claw 5, foolproof groove 6, rotation groove 7 and limit block 8. The foolproof claw 5 enters the rotation groove 7 from the corresponding foolproof groove 6. The foolproof claw 5 rotates in the rotation groove 7 so that the foolproof claw 5 contacts the limit block 8. Then the upper part 3 and the lower part 4 are axially rotated to the position, so that the contact 1 and the pad 2 are aligned, thereby achieving the effect of switching. The contact 1 and the pad 2 are both provided with a gold-plated layer, and the contact 1 is elastically retractable. The contact 1 and the pad 2 include a data pin and a power supply pin. The data pin is located near the center of the upper part 3 or / and the lower part 4, and the power supply pin is located at the outermost side of the contact 1 or / and the pad 2. During rotation, all contacts 1 are aligned from the middle to the periphery in sequence, and the power supply pin is the last to return to the position. When the power supply pin is returned to the position, all contacts 1 are in the correct position to achieve power-on.

[0024] The upper part 3 and the lower part 4 form a rotating part, and the foolproof claw 5, the foolproof groove 6, the rotating groove 7 and the limit block 8 form a foolproof part. The three foolproof claws 5 are evenly connected to the upper part 3, and the sizes of the three foolproof claws 5 are inconsistent. The rotating groove 7 is connected to the lower part 4, and three evenly distributed foolproof grooves 6 are opened on the outer wall of the rotating groove 7. The foolproof grooves 6 are connected to the foolproof claws 5 one by one. The foolproof claw 5 enters the rotating groove 7 through the foolproof groove 6. The limit block 8 is provided on the inner wall of the rotating groove 7, and the limit block 8 is staggered with the foolproof groove 6. The foolproof claw 5 is limited and rotated in the rotating groove 7 by the limit block 8, and the foolproof claw 5 contacts the limit block 8, and the contact 1 is aligned with the pad 2.

[0025] More specifically, the upper part 3 and the lower part 4 cooperate to form a rotating structure. When the rotation is in place, all the contacts 1 are aligned to power the device, which reduces the design of the switch and simplifies the operation steps of the device. The power supply pad 2 is left at the farthest end. When rotating, all the contacts 1 are aligned from the middle to the periphery in sequence, and the power supply pin is the last to return. When the power supply pin is returned, all the contacts 1 are in the correct position. This ensures the system integrity when powering on and improves the system safety.

[0026] The contact 1 part uses a gold-plated connector, and the pad 2 part uses a gold-plated pad, which improves the stability and life of the equipment in complex environments. Since gold is a very stable metal, it can ensure that the electrode will not be corroded when the power is on, and because gold is soft, it can reduce the wear of the contact part under conditions that require repeated installation, thereby increasing the service life.

[0027] The foolproof claws 5 and the foolproof grooves 6 are connected one by one to form a foolproof structure, so that the contact 1 and the pad 2 at the connection are accurately aligned. The problem of poor contact caused by inaccurate alignment of the contact structure is solved structurally, and the common problems of abnormal working of the contact connector such as equipment restart, data abnormality, etc. caused by unstable power supply due to poor contact are fundamentally solved.
