Cable bundle sheath

Abstract

The invention discloses a cable bundle sheath which comprises a joint end located at the tail end of a cable bundle, M fixing plates located in the middle of the cable bundle and connecting springs wound on the outer side of the cable bundle. The joint end comprises N joint through holes, and the fixing plates comprise N fixing through holes corresponding to the joint through holes; the joint endand the M fixing plates are connected through the connecting springs; and at least one cable penetrates through the joint through holes and the fixing through holes in the corresponding positions to form the cable bundle. According to the cable bundle sheath provided by the invention, the stress caused by the relative movement of the joint ends is uniformly dispersed, so that the cable is prevented from being broken due to stress concentration in the moving process.

Description

technical field [0001] The invention belongs to the field of semiconductor equipment, and in particular relates to a cable bundle sheath. Background technique [0002] In the process of assembling cables, it is necessary to use protective sleeves to protect the cable bundles. The use of protective materials with different materials and characteristics will make the assembled cable components in environmental resistance, mechanical wear resistance, softness and bending degree, etc. Aspects have different properties, and without a sheath, individual cables can become entangled, get caught and there is a danger of breaking. [0003] In the prior art, the length of the cable bundles is generally extended or the cable bundles are arranged in a flat shape to avoid the breakage of the cable bundles due to local stress concentration caused by pulling. as attached figure 1 As shown, by extending the length between the joint ends in the cable harness, the local stress on the cable h...

Problems solved by technology

[0004] However, when the cable bundle needs to move at a relatively large and high frequency, the above two structures still cannot avoid local stress concentration caused by pulling

This is because the cable is fixed relative to the sheath at every point in the length direction of the sheath. figure 1 The broken surface is hexagonal close-packed, with figure 2 The broken surface is rectangular, and the stress at the bend of the cable is relatively concentrated, which cannot be distributed to the entire length of the cable bundle; that is, the local stress generated is still difficult to distribute evenly
