Definitions

• the present invention relates to waterproof electrical connectors of the type where the seal is obtained by compression of a joint by the Imoyen of a movable element.
• the invention is particularly applicable in the field of automotive connectors, for which the connectors are wired on bundles and for which the sealing of the cable-side connector is ensured by an int crossed by several cables of variable diameter. .
• the gasket must have sufficient passageways for the passage of the electrical contacts and compression of the gasket by the movable element makes it possible to obtain a seal even for small diameter cables.
• a contact locking device having a position of n'hsertion contabts ei a locking position of the contacts ensuring that the contacts are not likely to move back when coupling the housing connector with a complementary connector housing carrying complementary contacts.
• US 4,998,896 describes in particular a three-part connector housing, a front coupling part with a housing of complementary connector, an intermediate contact retention portion, and a rear retaining portion of a rear sealing member provided with latching means with a complementary connector housing.
• the retention of the contacts is achieved by spring latches, carried by the intermediate part, which snap into a groove provided in the contacts.
• the nose of the contacts protrudes between the latches and, if a contact is slightly off-axis, it may interfere with the rear walls of the cell of the front part to receive it which must destroy the latch or bring out the pawl and lock the connector. ;
• a second problem is that it is possible to lock the contacts while the grommet is not properly applied to the cables and, in particular in the case of sealed connectors for automotive applications.
