ABSTRACT:
A connector for windshield wipers of low silhouette type has a sideways-extending pin that is inserted into a cooperating transverse aperture in the wiper superstructure and is retained therein by a spring latch member engaging a circumferential groove. The latch member is of spring wire and has two spaced parallel arms joined at one end by a cross-member. Each arm consists of at least a connecting portion, a pin-engaging portion, a spring portion and a reaction or anchor portion in the order stated, the last two having a loop portion between them. The latch is inserted into a recess formed in the underside of the superstructure primary yoke, the loop portion passing between two columns until they can snap apart over the top of the columns. Each pin-engaging portion moves against two longitudinally-spaced side columns which control the engagement with the pin retaining shoulders, and both portions engage a transverse projection that controls the latch portion when the pin is absent. These columns facilitate the final proving required to match the wiper superstructure to the latch. The cross-member moves in a topside counter-recess connected to the main recess by a narrow aperture through which the connecting portions pass, so that the material of the spring latch cannot be over-stressed.
