JPH01151295A - Packaging structure of movable cable - Google Patents

Abstract

PURPOSE:To make it possible to remove a line snap and increase a pulling stroke, by providing a guide such that a movable cable may not move from side to side and arranging a cable along the guide plate with one end of the guide rotatable. CONSTITUTION:A fixed point on the side of a unit 2 capable of pulling of a movable cable and a fixed point 32 on the side of a box are packaged such that a cable is along a guide 3 and a guide arm 10 in which one end of the guide 3 is rotatable. As a result, bending R of the cable can be increased until it is as large as the unit at the time of packaging. When the unit 2 is pulled, the shape of a semicircle of the plate guide 3 becomes a quarter circle and it is possible to pull the unit 2 in such a condition that the bending R of the cable 4 is large. When the unit 2 is housed, a rotation part of one end of the guide 3 rotates 90 deg. and the guide 3 changes its shape in contrast with the pulling, with the result that the cable 4 can be smoothly housed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to cable mounting to a pullout unit in a device equipped with a pullout unit, and is particularly suitable when the cable mounting area is small and the amount of pullout is large. It concerns a cable mounting structure.

[Conventional technology]

In the conventional mounting of a movable cable on a pull-out unit, as described in Special Publication No. 54-55721, the cable can move freely between the fixation on the pull-out unit side and the fixation on the housing side. was.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, since the cable is movable and depends on the sagging due to the cable's own weight, the cable tends to bend due to twisting of the cable when mounting the cable or pre-washing between the cables. There were problems such as cables protruding outside the mounting space, cables overlapping each other, and cables being caught between the drawable unit and the housing.In addition, the pull-out stroke was limited to twice the unit height. Because of this, it could not be used in devices that require a long pull-out stroke.

An object of the present invention is to solve the above problems.

[Means for solving problems]

The purpose is to provide a guide so that the movable cable does not move in the left-right direction, make one end of the guide rotatable, and route the cable along this guide plate. This eliminates smudges and allows for a larger pull-out stroke for the pull-out unit.

[Effect]

The movable cable can be pulled out.The fixing point on the unit side and the fixing point on the housing side are connected to a flat guide and one end of the guide is rotatable, and the cable is attached to the guide arm. The bending radius of the cable can be increased.

When pulling out the unit i+, the flat guide is semicircular. When you pull out the unit, it becomes 4 circles in one part, and the unit can be pulled out with a large bending radius of the cable. When storing the unit The rotating part at one end of the guide rotates 90 degrees and the guide deforms in the opposite direction of the drawer, allowing for smooth storage of cables.

〔Example〕

An embodiment of the present invention will be described below.

FIG. 1 is a cross-sectional view showing a state in which a drawable unit 9 2 is mounted on the device.
2, it is fixed to the cable guide 3 with a cable bundle band 20, passes through the fulcrum part provided at the bottom of the drawer unit 2,
It is connected to the drawer unit 2 through a connector 50.31 and is supplied with power.

FIG. 2 is a sectional view taken along the line I-I in FIG. 1. The drawable unit 2 is fixed to the unit base 5 with fixing screws 6, and is supported by slide rails 9 provided on both sides of the unit base 5 so that the drawer unit can be maintained. Therefore, it can be withdrawn.

The power supply cable is mounted in the minimum space between the drawer unit 2 and the housing 1.

As shown in FIG. 3, the fulcrum portion provided at the rear of the unit stand 5 is fixed to the cable guide 5 and the cable 4 to a U-shaped guide arm 10 with a bundle band 20.

The tip of the guide arm 10 is rotatable by 90° in one direction around a rotation shaft 12, and is fixed to the unit stand 5 via a guide arm holder 11. When pulling out the unit for maintenance inspection, The eight portions of the cable guide 3 move toward the skin as the unit 2 is pulled out, and when the amount of pull out is at its maximum, it is pulled by the cable guide 3 and the guide arm 10 is rotated upward by 90''.

When storing the unit, the guide arm 10 rotates until it becomes parallel to the unit stand 5.

As you store unit 2 further, cable guide 5
R gradually moves and becomes a mounted state.

Since the same volume as the unit space can be used for the cable bending radius, the bending radius can be increased, and cable breakage can be reduced even when the unit is frequently inserted and removed.

〔Effect of the invention〕

According to the present invention, the one-pullout unit can be stored and pulled out with a large pull-out stroke with a small mounting space, and the bending of the cable can be minimized, so that the cable can be moved stably.

Claims (1)

[Claims] 1. In cable mounting of a device in which a pullable unit is mounted, a rotatable guide arm is provided at a fixing point on the pullable unit side of the movable cable, and the guide arm and the fixing point on the housing side are made of a flat plate made of an elastic material such as plastic. A mounting structure for a movable cable, characterized in that by connecting the cable with a guide and wiring the cable along the guide, the elasticity of the guide is utilized to reduce bending, twisting, etc. of the cable.
