- the present invention relates to an electrical connection element. More specifically, this electrical connection element makes it possible to connect the end of at least one electrical wire having an electrical insulation sheath to a flexible sheet having parallel electric tracks.
- a first solution consists in welding ends of the electrical wires to the tracks of the flexible sheet.
- the welding is extremely delicate and such a connection does not ensure good mechanical strength, for example in the case where sheathed son and the web are stressed.
- a second known solution is to provide the flexible sheet with a male or female connector and to connect the jacketed son at a male or female conjugate electrical connector.
- the present invention aims to provide a less expensive electrical connection element and requiring a reduced number of assembly steps.
- the subject of the invention is an electrical connection element for connecting the end of at least one electrical wire having an electrical insulation sheath to a flexible sheet having parallel electrical tracks, characterized in that it comprises a holding portion having a bottom intended to be in contact with a stripped portion of the electric wire configured to be in direct contact with the sheet flexible, and at least one pin connected to the bottom and for piercing an associated electrical track and to be crimped to provide both an electrical connection and a mechanical holding between the electrical wire and the flexible ply, and a mechanical holding of the stripped portion of the electric wire against the flexible ply.
- the connection element may further comprise one or more of the following features, alone or in combination:
- the holding portion comprises at least one pair of lateral pins
- the pins of each pair are arranged in staggered rows
- the bottom of the holding portion comprises at least one resilient lamella; the lamella is produced by stamping in one piece with the bottom,
- the holding portion comprises two pairs of pins and a pair of crimping tongues of the stripped portion of the electrical wire disposed between the two pairs of pins,
- said connecting element comprises an additional portion of crimping of the sheath, made in one piece with the holding portion, and
- the additional crimping portion has in the unassembled state a U-shaped cross section whose legs are closed during crimping on the sheath of the electric wire.
- the invention also relates to a method of electrically connecting the end of at least one electrical wire having an electrical insulation sheath to a flexible sheet having parallel electrical tracks through a connection element as described above, characterized in that it comprises the following steps:
- An associated electrical track of the web is pierced by at least one pin of the connecting element and - the crimp is folded by crimping in the direction of the flexible sheet.
- This method may further comprise a crimping step of the pair of tongues around the stripped portion of the electrical wire.
- This method may also include a step of crimping the additional crimping portion around the sheath.
