Cavities capable of housing terminal fittings connected with the ends of electric wires W are provided inside of a housing. A rear assembly is assembled at the rear of the housing. The rear assembly includes a cover formed of a quality of material having no elasticity and a waterproof member formed of a quality of material having elasticity. The waterproof member further includes a wire seal part that surrounds and waterproofs electric wires, and a housing seal part that seals between the two housings. A clearance is provided about a periphery between the outer peripheral face of the wire seal part and the housing seal part. Even if the material of the wire seal part is deformed during the insertion operation of the electric wires, the insertion operation of the electric wires can be smoothly carried out to the last wire because the clearance absorbs the deformation of the entire wire seal part.

Waterproof connector

A connector is provided with a short longitudinal direction. The connector includes a housing ( ) with a cavity ( ). an electric wire ( ) extends to a position rearwardly of the cavity ( ), and is bent downwardly. A cover ( ) then is pressed against the housing ( ), with the electric wire ( ) sandwiched between sealing members ( ), ( ) made of a jelly-like material. As a result, the sealing member ( ) penetrates into the gap between confronting portions on of the housing ( ) and the cover ( ). The sealing members ( ), ( ) also are pressed against both sides of the electric wire ( ). As a result, the periphery of the electric wire ( ) is filled with the cover-side sealing members ( ), ( ).

To effect water-proofing using a non-water-proof type of female connector, a non-water-proof female connector (20) is fitted with a concave fitting member (12) of a male connector (10), a cover assembly (30) fitting with both the female connector (20) and the concave fitting member (12). The cover assembly (30) is provided with a ring-shaped seal (40) which fits tightly with the rim of the circumference of the fitting member (12), thereby sealing the portions of the two connectors (10) and (20) that fit together. A gel seal (45) is compressed between the cover assembly (30) and the rear face of the female connector (20), this preventing water from entering via terminal attachment holes (21) on the rear face of the female connector (20).

Connector

A connector is provided to prevent gelatinous seal members from being adhered to terminal fittings and improve the insertion operability of the terminal fittings. The connector includes a housing 11 with a rear surface that is held watertight since clearances between a cover 23 and the housing 11 and between the cover 23 and wires 15 are sealed by gelatinous seal members 40. Thus, female terminal fittings 14 are not brought into contact with the gelatinous seal members 40 while being inserted. Therefore, there is no likelihood that the gelatinous seal members 40 are adhered to the female terminal fittings 40 and that the viscosity resistance thereof acts on the female terminal fittings 14.

Connector with sealing members

An anti-skid device for use on pneumatic tires of an automotive vehicle includes a supporting ring rotatably provided on the outer circumferential periphery of a mounting plate that is detachably mounted on the wheel portion of the automotive vehicle, a plurality of ribs formed from a material having elasticity and toughness that are provided on the supporting ring in a radial fashion and are bent so as to extend from the outer side of a pneumatic tire to a tread thereof, first and second endless bands provided on the leading-end portion of each of the ribs in such a manner as to be located within the width of the tread of said pneumatic tire, rivets secured at portions where the first and second bands intersect the ribs, and a counter-measure provided on either of the first and second bands for preventing an imbalance in the degree of stretch between the first and second bands. Insertion and fixation holes each including a large diameter portion and a small diameter portion are formed in the mounting plate with the large diameter portions being designed to be opened and/or closed by stoppers after the leading-end portions of wheel nuts of the automotive vehicle have been put through the large diameter portions so as to be then moved to the small diameter portions to be secured in place therein.
