Abstract

An electrical connector (10) (e.g. a D.C. power plug) comprises a tubular electrical contact (12) and a connecting member (14) for electrically connecting the electrical contact (12) to an electric wire (16). The connecting member (14) is in use disposed substantially around the electrical contact (12) and an electrical contact therewith. A further connecting member (15) is used to connect a wire (17) to contact (13). <IMAGE>

Description

ELECTRICAL CONNECTOR The present invention relates to an electrical connector.
In known electrical connectors, such as jack-plugs, electric wires are connected directly to the corresponding contacts by soldering or crimping. Such soldering or crimping process involves handling of the electrical contacts which are relatively bulky, and could therefore be inconvenient and/or inefficient.
It is an object of the present invention to provide an electrical connector for which the soldering or crimping process can be carried out without handling the relatively bulky electrical contacts.
According to a first aspect of the invention, there is provided an electrical connector which comprises a tubular electrical contact and a connecting member for electrically connecting said electrical contact to an electric wire, said connecting member being in use disposed substantially around the electrical contact and in electrical contact therewith.
Preferably, the connecting member includes a tubular portion having a longitudinal slit.
It is preferred that the connecting member has at one end of the tubular portion a tang which is arranged to be electrically connected to a said electric wire by crimping.
In a preferred embodiment, the electrical connector further comprises a second tubular electrical contact and a second connecting member for electrically connecting said second electrical contact to another electric wire, said second connecting member being in use disposed substantially around the second electrical contact and in electrical contact therewith.
Other preferred and/or optional features of the first aspect of the invention will be apparent from the accompanying claims 5 to 7.
According to a second aspect of the invention, there is provided an electrical connector which comprises two elongate electrical contacts which are arranged to lie along substantially the same axis, and at least one connecting member for electrically connecting an electric wire to a said electrical contact, said connecting member being in use disposed substantially around the said electrical contact and in electrical contact therewith.
The invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a side elevation of an embodiment of an electrical connector in accordance with the invention; and Figure 2 shows the electrical connector of Figure 1 with parts thereof separated.
Referring to the drawings, there is shown an embodiment of an electrical connector in the form of a D.C. power plug 10 which comprises an electrically insulating tubular plastics support 11, and two electrical contacts 12 and 13 disposed on, respectively, the external and internal surfaces of the support 11. The external contact 12 is tubular and the internal contact 13 has a tubular front end 13a and a solid rear end forming a post 13b.
Two resilient, electrically conducting members 14 and 15 are provided for electrically connecting two electric wires 16 and 17 to the electrical contacts 12 and 13, respectively. The connecting member 14 includes a tubular portion 18 and a tang 19 for in use connecting with the contact 12 and the wire 16, respectively. The tubular portion 18 has a longitudinal slit 18a, and is adapted to clip co-axially onto the rear end of the contact 12. The tang 19 includes two pairs 19a and 19b of opposed lugs which are adapted to crimp the exposed metal core and the sheath end of the wire 16. The lugs 19a serve to provide the electrical connection, whereas the lugs 19D serve to provide a mechanically stronger connection.
The connecting member 15 includes a tubular portion 20, having a smaller diameter than that of the tubular portion 18 of the connecting member 14, for in use connecting with the post 13b, and a tang 21 for in use connecting with the wire 17. The tubular portion 20 has a longitudinal slit 20a, and is adapted to clip co-axially onto the post 13b. The tang 21 includes two pairs 21a and 2-lb of lugs which are to be connected with the wire 17 in the same manner as described above in relation to lugs 19a and 19b.
As shown in Figure 1, the connecting members 14 and 15 are located at the rear end of the plug 10. This end of the plug 10 is enclosed by moulding a plastics material therearound so as to provide a hand grip and to protect the connections, as shown by the dotted lines. In a modified embodiment, not shown in the drawings, a plastics end cap is used to enclose this plug end, and the two are connected together by screw-threading.
It is conceived that the plug could have only one, or more than two, electrical contacts.
The electrical connectors in accordance with the invention can be connected to electric wires in a more convenient way than those in the prior art.
The invention is described by way of example only, and various other modifications and/or alternations would be apparent to persons skilled in the art without departing from the scope of the invention.

5. An electrical connector as claimed in claim 4, wherein the two electrical contacts are co-axially located with respect to each other, and are electrically insulated from each other.
6. An electrical connector as claimed in claim 5, wherein each connecting member is electrically connected to a proximal end of the corresponding electrical contact.
7. An electrical connector as claimed in claim 6, wherein the end of the connector including said ends of the electrical contacts is enclosed in plastics material.
8. An electrical connector comprising two elongate electrical contacts which are arranged to lie along substantially the same axis, and at least one connecting member for electrically connecting an electric wire to a said electrical contact, said connecting member being in use disposed substantially around the said electrical contact and in electrical contact therewith.
9. An electrical connector substantially as hereinbefore described with reference to the accompanying drawings.
