Abstract

A method of installing a cable (16) at a spaced position from an apertured or slotted support (17) is distinguished by using a resilient spring clip (11) comprising two arms (12) which are jointed at one end and which have extensions (13) at their free ends at an angle to the arms. The arms have a shaped portion (14) at the joined ends within which the cable can be secured. The arms can move relative to one another against the resilience of the clip for passing each extension through an aperture (18) or slot in the support, and then released so they tend to spring back with each extension engaging a wall of the support to secure the clip to the support. <IMAGE>

Description

SPECIFICATION Cable installation This invention relates to a method of installing a cable, for example, a heat detector cable; a cable installation, and a clip for use in the installation.
According to the present invention a method of installing a cable at a spaced position from an apertured or slotted support is distinguished by using a resilient spring clip comprising two arms which are joined at one end and which have extensions at their free ends at an angle to the arms, the arms having a shaped portion at the joined ends within which the cable can be secured, so that the arms can be moved relative to one another against the resilience of the clip for passing each extension through an aperture or slot in the support, and then released so they tend to spring back with each extension engaging a wall of the support to secure the clip to the support, and the cable can be positioned in the shaped portion of the clip to secure the cable in the clip.
The cable may be positioned and secured in the shaped portion of the clip before or after the clip is secured to the support.
The invention also includes a resilient spring clip for use in an installation herein described, the clip comprising two arms which are joined at one end and which have extensions at their free ends at an angle to the arms, the arms having a shaped portion at the joined ends within which the cable can be secured.
Where the resilience of the clip tends to push the arms apart the extensions project outwardly, and vice versa.
The free ends of the arms of the clip may have two extensions, in this case the clip can be secured to the apertured or slotted support such that a wall of the support is positioned between the two extensions of each arm.
The shaped portion of the clip is preferably so shaped that it substantially surrounds the cable, the resilience of the material of the clip securing the cable in the shaped portion.
The invention further includes a cable installation as hereinbefore described.
An aperture support may comprise a cable ladder, cable tray, or a punched panel.
A slotted support may comprise a substantially U-shaped channel in which the free ends of the side walls of the channel are turned inwardly. In this case the free ends may project towards the base of the channel, the free ends either being smooth (in which case the extensions of the arms of the clip may be shaped to wedge against the side walls of the channel) as sold by BICC Vantrunk Limited, under the trade mark "Leprack", or toothed (in which case the extensions on the arms of the clips may be grooved to engage in the teeth) as sold by BICC Vantrunk Limited under the trade mark "Intelok".
The invention is further illustrated, by way of example, with reference to the accompanying drawings, in which:~ Figure 1 is an end view of a resilient spring clip in accordance with the invention; and Figures 2 and 3 are perspective and crosssectional views of a cable installation in accordance with the invention.
Clip 1 shown in Figure 1 comprises two arms 2 which are joined at one end and which have extensions 3 at their free end at an angle to arms.
The arms 2 have a shaped portion 4 at the joined end within which a cable can be secured.
Figures 2 and 3 show a cable installation 10 in which an alternative form of resilient spring clip 1 1 to that shown in Figure 1 , is used to install a heat detector cable 16 at a spaced postion from an apertured support in the form of a cable ladder 17. In this arangement the clip 1 1 comprises two arms 12 which are joined at one end and which have extensions 13 at their free end at an angle to the arms. The arms 12 have a shaped portion 14 at the joined ends within which the cable 16 is secured. Each arm 12 also has an additional extension 1 5 adjacent extension 13.
This arrangement is assembled by positioning the clips 1 1 on the cable 16, pushing the arms 12 of each clip towards one another, passing extensions 13 through an aperture 18 in the ladder 17 and releasing the arms so they spring back to leave the extension 1 5 of each arm on one side of the ladder, and extension 13 on the other side.
Although the installation 10 is shown with the cable 16 supported above the ladder 17, the invention is not so restricted. The cable may be suspended below the ladder or other support by the clips herein described.
The clips 1, 11 are made of sprung steel and have a plastics (eg PVC or epoxy resin) coating to avoid possible damage to the cable by the sharp edges of the steel. Other suitable materials may, of course, be used.
