MHF^® Series Locking Function

The MHF^® micro RF connector series has an LK type equipped with a locking function. Its patented mechanical locking feature greatly improves the plug retention force compared to common micro RF connectors in the same category in the market.

Compared to the MHF^® 4L Connector, which is a general friction lock type micro RF connector that does not have an additional mechanical lock function, the initial plug mating retention force of the MHF^® 4L LK with mechanical lock applied is doubled. In addition, after mating and unmating the MHF^® 4L LK Plug 30 times without applying mechanical lock, the mating retention force with mechanical lock is about three times that of the MHF^® 4L Connector. This high retention force makes it possible for the MHF^® 4L LK to ensure high signal connection reliability even under the continuous impact and vibration from road conditions.

The high mating retention force helps to improve assembly efficiency on the production line and helps reduce product manufacturing costs by reducing the additional banding tape or adhesive application process to ensure that the connector stays mated in the production line. It also reduces fixture material removal process during maintenance or inspections.

Locking / Unlocking Method and Locking Status Check

​In addition, the connector’s simple and easy-to-understand one action locking and unlocking mechanism (sliding the lock cover back and forth) and the “check window” function that allows the user to visually check the lock status enhance the reliability of the lock during handling.

With the development of communication technologies such as IoT and 5G, the digitization and networking in the automotive market will continue to grow. Further development of integrated intelligent cockpits and head units equipped with wireless communication functions is happening more frequently.
The MHF^® 4L LK Connector won wide acclaim from customers' production line Supplier Quality engineer as an ideal product for such wireless communication devices that need to ensure stable connectivity.
