Abstract

Usually the cover of a connector is delivered to harness maker with the lever assembled on it. This lever must be positioned on the cover, after wiring, in a fixed and correct position for the final assembly on the connector. To insure that the lever does not move from the delivery stage during the shipment operations (packaging, transportation, shocks) a known solution is to put a fix bump on the cover, which has interference with the lever arm. This concept does not insure the blocking position of lever especially in case of shock or drop. The obvious solution would be to increase the interference between the bump on cover and the lever, but thus leads to a higher force to release the lever prior the mating on pin header. To avoid any negative impact on the force to release the lever from delivery position, when the connector is in mating position, a new concept with a flexible latch has been designed. The cover housing comprises a flexible latch that is a part of the wall of the cover housing. The flexibility is given because the latch is a strip of material of the cover housing, remaining attached with one end at the cover housing. In the area where the strip is connected to the cover the strip can be bend a little. As far the strip is only bend in small limits the flexibility is given by the material itself. A bump is formed on the outer surface of the flexible latch. The latch has a sloped area on the free end. In delivery position the lever is blocked by the bump. The force that is needed to bend the flexible latch on the position of the bump, is high enough to prevent an accidently movement of the lever over the bump, while the connector is not connecting the counterpart. During assembly the cover housing to the counterpart (connector housing), the latch is easily pushed toward the housing. The sloped area glides along the counterpart (connector housing) and the latch is bend easy. The necessary force to bend the latch is low at the free end. When the latch is bend towards the connector, the bump is no longer limiting the lever and the lever can be operated to pull together the two parts. While disassembling the two parts the steps are done the other way round. After disassembling the lever is fixed in delivery position.
