Abstract
The invention relates to a metal switch grid 1 which normally mounts a switch or switches (not shown) which are normally connected to mains supply. The switch grid 1 has a terminal 2 whereby a flying earth lead 3 can be connected permanently, for subsequent connection with an earth point such as the box to give earth continuity. The terminal 2 comprises two U-shaped members 4 which are struck out of the plane of the switch grid 1, the ends of the limbs of the members being an integral part of the switch grid. Striking the members out of the plane of the grid provides two spaced generally rectangular slots 5 in the grid, under the respective 'U'-shaped members 4. A flying lead 3 is permanently connected with the grid 1 by stripping the insulation from one end 6 and feeding that end 6 through the U- shaped members 4 and then crimping them down onto the exposed end 6 to provide a firm, metal-to-metal and hence positive electrical connection between the grid 1 and the lead 3 which is thus permanently connected with the grid 1. <IMAGE>
Description
SPECIFICATION
Switch grid
The invention relates to a switch grid.
According to the invention there is provided a switch grid comprising a terminal whereby an earth lead may be connected permanently with the grid.
The terminal may comprise a part of the switch grid which is adapted to be crimped onto an earth lead whereby to provide the permanent connection therewith.
The part of the grid may comprise a 'U'shaped member struck out of the grid.
There may preferably be two U-shaped members. This provides a firmer connection when the members are in use crimped onto the earth lead.
The invention extends to a switch grid as hereinbefore defined to which an earth lead is permanently connected.
A switch grid embodying the invention is hereinafter described, by way of example, with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a schematic plan view of a switch grid according to the invention, without switches, and to which is permanently connected an earth lead; and
Figure 2 is a schematic perspective view of the switch grid of Fig. 1 with the flying lead omitted for clarity.
Referring to the drawings there is shown a metal switch grid 1 which normally mounts a switch or switches (not shown) which are normally connected to mains supply. The grid 1 is mounted in a metal box which is installed in a wall say and after finishing the wall as by decorating, a cover is placed thereover. The switch grid 1 has a terminal 2 whereby a flying earth lead 3 can be connected permanently, for subsequent connection with an earth point such as the box to give earth continuity. The terminal 2 comprises two Ushaped members 4 which are struck out of the plane of the switch grid 1, the ends of the limbs of the members being an integral part of the switch grid. Striking the members out of the plane of the grid provides two spaced generally rectangular slots 5 in the grid, under the respective 'U'-shaped members 4.A flying lead 3 is permanently connected with the grid 1 by stripping the insulation from one end 6 and feeding that end 6 through the Ushaped members 4 and then crimping them down onto the exposed end 6 to provide a firm, metal-to-metal and hence positive electrical connection between the grid 1 and the lead 3 which is thus permanently connected with the grid 1. The other end of the lead can then, after installation of the grid and box, be connected to the earth point to give earth continuity. Thus, in the event that any cable carrying current to a switch on the grid becomes loose or disconnected, the earth lead 3 provides that the whole box does not become "live" so obviating any risk of fire or personal injury.
Providing the flying lead on the switch grid means that installation is made easier.
