SMC Secure Lock Connectors
Double safe connections
The SMC family with a 1.27 mm pitch is also recommended for demanding, often spatially confined applications in the automotive sector. And the development continues – as the SMC Secure Lock shows. The SMC connector family has thus been extended to include versions with Secure Lock interlocking. The highly reliable electrical contact of the Secure Lock versions is provided when mated by the proven double-shank spring contact. The wire-to-board solution (connector system with IDC female connector and SMT male connector) was modified and optimized to meet, for example, the increased requirements of the automotive industry as well as modern automation technology for the safe mechanical connection of two assemblies. This means that even the most demanding applications, such as in inverters of electric/hybrid vehicles, can be addressed. Reliability in the locked state (e.g. under vibration and shock loads) is just as important as the precise and error-free mating process.
The geometry of the angled IDC female connector and the straight SMT male connector requires a defined force to lock the wire-to-board connection. The user thus receives a clear acknowledgement (audible, tactile) that the connection has been securely made. With additional guides and widened locking levers, contact damage when mating is ruled out. The connection is released using a cost-effective unlocking tool. With the 50-pin SMC Secure Lock connectors, compact and reliable ribbon cable assemblies can be realized.
