A thick-film sheet member producing method including: (a) a support-body preparing step of preparing a support body having a film formation surface provided by a particle layer constituted by high-melting-point particles which are held together with a resin and which have a melting point higher than a predetermined temperature; (b) a paste-film forming step of forming a paste film on the film formation surface, by applying a paste onto the film formation surface; and (c) a firing step of subjecting the support body on which the paste film has been formed, to a heat treatment effected at the predetermined temperature, so as to burn the resin included in the particle layer, whereby the high-melting-point particles become unbound from each other in absence of the resin that has been burned. The paste film is sintered in the firing step, whereby a thick film is formed of the sintered paste film.

A waterproof structure is provided for a connector wherein a terminal 3 to which a power line 4 is attached is retained in a connector housing 2 and a waterproof sealing member 9 is disposed between the connector housing 2 and the power line 4; wherein a front end 11 of the waterproof sealing member 9 is secured to the power line 4 and a rear end 12 of the waterproof sealing member 9 is secured to the connector housing 2; and wherein a stretch portion 14 is formed between the front end 11 and the rear end 12 of the waterproof sealing member 9. Reinforcement portions 19 and 20 are internally formed between the front end 11 and the rear end 12 of the waterproof sealing member 9. When the stretch portion 14 is extended, the front end 11 of the waterproof sealing member 9 abuts against a wall 24 of the connector housing 2, and the rear end 12 abuts against a rear holder 10 attached to the connector housing 2. This waterproof structure for a connector is applied for a power feed connector.

An insulator including an insulator body, a metal fitting secured to the insulator body via cement material, a conductive layer provided on the insulator body, the conductive layer including a first exposed portion and a second portion embedded in the cement material, and a conductive covering film provided on the second portion of the conductive layer. A conductive grain layer is on the second portion of the conductive layer and is covered by the conductive covering film. According to the present invention, the conductive covering film is more flexible than the second portion of the conductive layer. The present insulator has a simple construction, is easy to produce, and assures continued electrical conduction through the cement material over time.

A connecting structure in which a male connector can be fitted into a female connector by operating a joint lever is provided. The joint lever is rotatably attached to either the male connector or the female connector. The connecting structure further includes projections to be inserted into the guide grooves and a fit detecting member for detecting the fitting condition between the male connector and the female connector. In fitting the male connector into the female connector, the fit detecting member is released from its engaged condition in the temporary engagement position by rotation of the joint lever. In the case where the fit detecting member is engaged in the formal engagement position, the fit detecting member operates to prevent the joint lever from being rotated.
