Abstract: This invention is concerned with improvements in or relating to methods of mounting circuit components on flexible substrates and, in particular, surface mounting components to the conductors of printed circuits on flexible substrates having relatively low temperature heat resistance using soldering techniques. A carrier assembly and the assembled circuits are also part of the invention.

Abstract: An electrical connector (10) comprises a housing (12) housing electrical contacts (14). The housing (12) has securing means (16) which help secure the connector (12) to a printed circuit (18) (which may be flexible) comprising contacts (22) each including a back portion (24) having two sets of deformable spaced parallel legs (26). In an open position a contact (22) can be received between the legs (26) which can be crimped to a closed position to clamp them in contact with the contact (22).

Abstract: A connector (12) for flexible printed circuits comprises connector contacts (22) associated with a moulded plastics body (10) each having a first terminal (24) for connection to conductors of the printed circuit and a second terminal (28) e.g. providing part of a plug connector and a securing member (30) attached e.g. by ultrasonic welding retaining the contacts (22) in position and have moulded therein discharge contacts (36) each spaced from a respective one of the contacts (22) by a distance (which may be chosen according to the discharge voltage required) corresponding to a desired spark gap. Preferably the connector (12) has means (34) associated with the member (30) by which the connector is secured in a desired position e.g. on a car body. Preferably the contacts (36) are connected to a common conductor (38) which is earthed e.g. by contact with a screw used with the means (34) to secure the connector (12).

Abstract: An electrical contact to be made between an electrically insulated first conductive strip and a socket member having an electrical contact element therein in which a crimpable, electrically conducting, second strip is caused to pierce the first strip at two separate points after which the passed-through ends of the second strip are folded over into a region of the first strip between the two pierced points to pierce again the insulation of the first strip to effect a second electrical connection with the first strip, and the resultant crimped joint is then inserted into the socket member until at least two electrical connecting points are established between the crimped second strip and the contact element in the socket member.
