The PCB socket blocks available from Weidmuller are with integrated lock and release lever.
Practical detail with two functions: interlocking with the pin headers provides additional safety as well as precise, force-free separation of the plugged connection.
There is a natural limit to the constant miniaturisation of electronic components and concurring high density of components, the user’s hand.
To get around this limitation, Weidmuller has equipped its 5.08mm pitch socket blocks BLZ, BLZF and BLT, left and right, with a lock and release lever.
This practical detail fulfills two functions: on the one hand, it interlocks the socket block and the pin headers; thus guaranteeing a secure connection.
On the other hand, when the release lever is operated the specially curved design separates the socket block from the pin header completely, precisely and without force.
Engineers talk of defined ejection characteristics. Of course, locking and unlocking requires no tools. So in order for the user to be able to take advantage of these socket blocks, the pin headers had to be fitted with a flange on either side.
The reason is, that the lock and release lever requires a bracing surface for leverage and interlocking functions; thus the design engineers had to take this constructive detail into consideration when designing this section of the module housings.
The new socket blocks are fully compatible with SL-SMT (surface mount technology) pin headers. Weidmuller is extending the Omnimate range by adding these modules to its programme.
The socket blocks are made from the insulating material PBT; flammability class UL 94 V-0. PBT is thermoplastic polyester, thus providing good dimensional stability, so it will not shrink away from continuous high operating temperatures.
