Abstract

The invention relates to an electrical connector with an earth wire. Connector 1 has a first substantially U-shaped connector body 2 adapted to engage over the edge of a section of metal sheet, such as metal capping for cables (X, Fig 2), whereby opposing inner faces of the body abut opposing outer faces of the section of metal sheet. A wire 6 has a first end 6A bonded to the U-shaped connector body 2. There may be a similar connector on the other end of the wire. The connector may have slanted teeth 4A, 5A to prevent removal of the connector, and may be coated with plastic on the outer faces.

Description

Title: Electrical Connector With Earth Wire The present invention relates to an electrical connector with earth wire, especially for use with metal capping.
It is common practice to use metal capping to guide wires to an enclosure for an electrical accessory. Such metal capping needs however to be earthed electrically, e.g. connected to the "common earth" a circuit being protected by the capping. It can be very time consuming ensuring that all lengths of capping are electrically earthed.
The invention seeks to provide an electrical connector with an earth wire to facilitate earthing lengths of capping.
According to the present invention there is provided an electrical connector with earth wire comprising: a) a first substantially U-shaped connector body adapted to engage over the edge of a section of metal sheet, whereby opposing inner faces of the body abut opposing outer faces of section of metal sheet, and b) a wire having a first end bonded to the U-shaped connector.
A second substantially U-shaped connector body similar to said first substantially U-shaped connector body is connected to a second end of said wire.
Preferably one way movement means are provided on the or each substantially U-shaped connector body allowing the or each body to be pushed onto an edge of metal sheet but not pulled off Preferably the or each substantially U-shaped connector body has at least one inner opposing face with teeth thereon. Preferably both inner opposing faces have teeth thereon.
Preferably the teeth are slanted to provide said one way movement means.
Preferably the or each substantially U-shaped connector body is coated with plastic on its outer surface.
Preferably the or each U-shaped body is formed from a rectangular base with rectangular arms extending from opposing edges of the base.
The invention also relates to a method of earthing capping comprising applying the above defined connector with earth lead to a section of capping and electrically earthing the earth lead.
Embodiments of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a perspective view of a connector with earth lead, Figure 2 shows a perspective view of the connector of Figure 1 on the edge of a section of metal capping, and Figure 3 shows double connector.
Referring to Figure 1 there is shown an electrical connector with earth wire 1.
Connector 1 has a first substantially U-shaped connector metal body 2 adapted to engage over the edge of a section of metal sheet (see Figure 2). Body 2 has a rectangular base 3, with rectangular arms 4,5 extending from opposing edges of the base.
Rectangular arm 4 has an inner face formed by the ends of an array of teeth 4A in the form of elongate blades which slant towards the rectangular base 3. Rectangular arm 5 has an inner face formed by the ends of an array of teeth 5A in the form of elongate blades which also slant towards the rectangular base 3.
An earth wire in the form of a fly lead 6 is bonded at one end 6A to the outer face 4B of rectangular arm 4.
Preferably the U-shaped connector body 2 may be coated with plastic on its outer surface.
It is envisaged that the connector body 2 could be extruded as a continuous length and then cut into sections with each section forming a connector body.
As shown in Figure 2, connector with earth lead I can be pushed onto the edge of metal sheet such as the edge of capping "X" whereby opposing inner faces provided by the ends of teeth 4A,5A of the body 2 abut opposing outer faces of a section of capping "X". The slanted teeth 4A,5A provide one way movement means allowing the body 2 to be pushed onto the edge of capping X, but not pulled off. In this respect teeth 4A,5A may be flexible. The gap between the ends of the teeth may be slightly less than the thickness of the capping "X" so that the teeth are flexed when the body 2 is pushed onto the capping.
Also when the body 2 is pushed onto the capping, the teeth 4A,5A tend to scratch the surface of the capping so that the teeth make good electrical contact with the capping.
In use fly lead 6 can be connected to "earth" so earthing the capping "X", e.g. to the "common earth" of the circuit being protected by the capping.
As shown in Figure 3, there is shown a connector with earth lead 10 identical to connector with earth lead I shown in Figure 2, except that two substantially U-shaped connector bodies 1 2A, I 2B (similar to first substantially U-shaped connector body 2) are connected to first and second ends 16A,16B of a wire 16. The embodiment shown in Figure 3 can be used to earth two surfaces of metal together.
The invention may take a form different to that specifically described above. For example instead of elongate blades, the teeth could be individual spikes. Also teeth could be provided on just one arm 4A or 5A rather than both arms.
The invention also relates to a method of earthing capping comprising applying the connector with earth lead described above to a section of capping and electrically earthing the earth lead.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
