Abstract
A cable connection is described. It is particularly suitable for a piezoelectric cable which has a low melting point conductor. The connection is made by inserting a conductive piercing member such as a wire (14) into the conductor (4), so as to leave a portion of the piercing member extending from the cable. The piercing member (14) is then heated to the softening temperature of the cable conductor (4) to allow local softening of the conductor. The result, on cooling, is a solder joint between the piercing member and the cable conductor.
Claims11
A method of forming an electrical connection, comprising:
- (i) providing an electric cable having a conductor with a softening temperature surrounded by electrical insulation material, and a conductive piercing member,
- (ii) inserting the piercing member into the conductor of the cable so as to leave a portion of the piercing member extending from the cable,
- (iii) heating the piercing member to at least the softening temperature of the conductor so as to produce local softening of the conductor, and
- (iv) allowing the piercing member and the conductor to cool so as to form a solder joint therebetween.
An electrical connection between an electric cable and at least one other cable, the electric cable comprising a conductor having a softening temperature surrounded by electrical insulation material, and having a piercing member with a softening temperature retained within the conductor and extending from the electric cable, wherein the softening temperature of the conductor is below that of the piercing member, and the piercing member is soldered at one end thereof to the said conductor and is connected towards another end thereof to a conductor of the said at least one other cable.
