Crimp connections enjoy popularity in several applications, such as automotive, electrical, and construction. In both types of this connection, a contact is crimped on to a prepared wire prior to the connection being made. In the case of standard crimp connections, this contact is inserted into a housing which mates to another connector. In contrast, the crimped fast-on contact is connected to a mating contact which may or may not be inside a housing. Fast-on style contacts are also widely used in household electrical and electronic applications. Both crimp connection styles have the advantage of providing a secure, long lasting connection due to their inherent temperature stability as well as a secure gas tight contact with the wire being terminated. Standard crimp configurations offer a great deal of flexibility in contact design for highly specialized applications such as the harsh environment found under the hood of car. The fast-on configuration excels at ease of wiring, capable of rapid connection and disconnection. Several suppliers offer highly automated crimping equipment, dramatically reducing the cost of wire preparation in higher volume applications. However, for lower volumes, the cost of wire preparation climbs as these same steps must be done manually. The other disadvantage of crimp connections is that repair requires the appropriate tools and replacement contacts, which may or may not be readily available.
