» This example of overmolding demonstrates its ability to manage different angles for an easier installation of the link while ensuring its protection.
Managing changes in direction typically involves cable assemblies or round cables, which can be oriented in any direction. Flat cables with flat conductors, called flat flexible cables (FFCs), which are often utilized in applications with restricted spaces, can naturally be oriented only in one direction. However, folding techniques are possible and even recommended for FFCs, for example, a 90° direction change. Several folds can then be made consecutively without damage. In some applications, it may be useful to hold them in position and protect them mechanically with an overmold. High-pressure injected thermoplastics are particularly suitable for mass production.
» Folding of an FFC before overmolding
This is the case, for example, with FFCs designed for airbag cassettes on the driver’s side of a car, where the space available in the steering wheel is reduced. In addition, an overmolded form such as a clip can be provided to help secure the cable in the system. The overmold is extended to the mobile connector external to the cassette to protect
