Problems solved by technology

[0004] However, when the flexible multi-sleeve included in the existing cable protection device is applied to moving bodies such as working machines, electronic equipment, industrial robots, transportation machines, etc., due to repeated bending movements, the flexible multi-sleeve that constitutes the structure may be damaged. The junction of the upper flexible member and the lower flexible member of the multi-sleeve is partially damaged, a gap may be formed between the upper flexible member and the lower flexible member of the damaged junction, and dust etc. inside the pod pass through Such gaps flow out to the outside, resulting in process errors during the production of high-precision and high-purity products, or adjacent cables may be damaged due to mutual friction

Embodiment

[0088] After manufacturing the multi-sleeve whose specifications are shown in Table 1 below, one end thereof is sealed with a clamp, and air is simultaneously injected into all grooves through the other end, thereby measuring the due to The air pressure at the point of partial rupture due to failure to withstand. The measurement results are shown in Table 1 below.

[0089] [Table 1]

[0090]

[0091] As shown in the above-mentioned Table 1, in the multi-sleeve for a cable-type protective device according to the present invention, it has been confirmed that the joint portion of the upper flexible member and the lower flexible member has excellent durability, so that even under high internal pressure The above-mentioned joint part is also not damaged, thereby, even during the repeated bending movement of more than 10 million times, the above-mentioned joint part will not be damaged, so it is possible to prevent the gap caused by the dust inside the groove passing through the...

Abstract

The invention relates to a multiple sleeve for a cable protection device and a cable protection device including the same. Specifically, the present invention relates to a multi-sleeve for a cable-type protection device and a cable-type protection device including the same, wherein the sleeve not only protects moving bodies such as working machines, electronic equipment, industrial robots, and transportation machines that repeatedly move The cables used in are protected and further stably supported to suppress breakage of the cables, and also have excellent durability so that they are not broken even by repeated bending movements, so they have high reliability, and as a result suppress the damage caused by Process error and cable damage caused by dust, so it is suitable for the production process of high-precision and high-purity products such as semiconductor wafers.

Description

technical field [0001] The invention relates to a multiple sleeve for a cable protection device and a cable protection device including the same. In particular, the present invention relates to a multi-sleeve for a cable-type protection device and a cable-type protection device including the same, wherein the sleeve not only protects against movement of working machines, electronic equipment, industrial robots, transportation machines, etc. The cables used in the body are protected and further stably supported to suppress breakage of the cables, and also have excellent durability so that they will not be broken even by repeated bending movements, so they have high reliability, and as a result suppress Due to process errors and cable damage caused by dust, it is suitable for the production process of high-precision and high-purity products such as semiconductor wafers. Background technique [0002] In electric wire cables, optical fiber cables, fluid supply hoses, flexible c...
