Embodiment 1

[0021] Refer to attached Figure 1a , Figure 1b , Figure 1c , The present invention provides Referring to the accompanying drawings, the present invention includes a towline 1, a towline guide rail 2, a relatively fixed end 3, a relatively movable end 4, a towline free area 5, a rotating component 6, and a fixed component 7.

[0022] The drag chain 1 is a finished product in the present invention, and its specifications and models are determined according to the internal cable specifications. The drag chain guide rail 2 has a circular structure with a U-shaped cross-section, and the material is not limited. The drag chain guide rail 2 is provided with a drag chain inlet and outlet, where the drag chain 1 enters the drag chain guide rail 2, and the drag chain 1 completes the rotation and reversing here. ( Figure 1b ).

[0023] One end of the drag chain 1 is fixed on the relative movable end 4, and the relative movable end 4 is fixed on the rotating part 6. The other end o...

Embodiment 2

[0027] combine figure 2 As shown, all the other structures are the same as in Embodiment 1, the difference is that the relative movable end 4 connected with one end of the drag chain 1 is fixed on the fixed part 7, and the free movable area 5 of the guide rail 2 and the bottom surface coplanar with the guide rail 2, and The opposite fixed end 3 connected to the other end of the towline 1 is all arranged on the rotating part 6, and the guide rail 2 rotates with the rotating part 6. Although the relative movable end 4 is fixed, its relative rotating part 6 completes the movement range of ± α angle. That is, the rotating part 6 rotates 2α, and the drag chain 1 can ensure that the cables will not be entangled or knotted. It can also be realized in a reciprocating circular motion greater than 360° and less than 720°.

Abstract

The invention discloses a cable connection device used in a rotary structure. The cable connection device comprises a fixed component and a rotary component connected with the fixed component through a shaft, and further comprises a tow chain and a guide rail, wherein the tow chain slides in the guide rail; an inlet allowing the tow chain to enter is formed outside the guide rail; two ends of the tow chain are respectively connected with a relatively fixed end and a relatively movable end; the relatively movable end is arranged in the guide rail and adopts a hollow rotatable structure; and a cable directly enters the central hole of the relatively movable end after penetrating the tow chain. Owing to the above structure, the movable end of the tow chain rotates by + / - Alpha when the rotary structure needs to rotate by the degree of 2 Alpha (2 Alpha is larger than 360 DEG and smaller than 720 DEG) as required to achieve rotation of the total angle required by the rotary structure.

Description

technical field [0001] The present invention relates to the technical field of machinery, in particular, the present invention relates to a cable connection device for transmitting signals and power between dynamic and static components during mechanical rotation through cables. Background technique [0002] In the design of rotating machinery, when the rotation angle is greater than 360 degrees, the slip ring structure is usually used to realize the signal and power transmission between the dynamic and static. However, the slip ring structure has disadvantages such as difficult processing, high cost, limited digital signal transmission rate and regular replacement of contacts. [0003] In view of the deficiencies in the prior art, the present invention is proposed. Contents of the invention [0004] In order to solve the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a simple and reliable connection structure between the ...
