Abstract: Disclosed are a locking device and an assembly of conjugated electric connectors equipped with the locking device. The device includes: at least one latch presenting a first locking relief, at least one bolt that can be inserted into the latch, and a flexible tongue received in a casing of the bold, the tongue being provided with a second locking relief forming a fitting with the first locking relief. Application includes the implementation of connectors and in particular of high-power connectors for vehicles and electric pieces of equipment.

Abstract: Disclosed is a sleeve for a female contact, its method of manufacture, and also a connector using the sleeve. The sleeve is provided with a first end and a second end presenting, respectively, a rotary symmetry around a common axis, the ends being inter-connected by a plurality of contact blades. Each contact blade presents connecting sections linking the median part of the blade to the first and the second end respectively. The connecting sections describe at least one truncated surface. Applications include the implementation of connectors for high intensity currents, usable especially for electric vehicles.
