Abstract: An electrical connector is provided including a housing supporting an electrical device and for receiving an electrical cord or cable. A cap having internal threads and an axial passage for receiving the electrical cord and clamping the electrical cord to the housing to form a waterproof connection. The cap includes a conical shaped seal member for forming a waterproof seal with the outer surface of the electrical cord. A conical shaped bushing is received in a frustoconical shaped bore of the housing and is axially and radially compressed by the threaded cap onto the housing. The bushing has an axial bore for receiving the electrical cable and an outer surface with at least one annular recess to facilitate the axial and radial compression of the bushing. The bottom end of the cap has a chamfered edge which mates with a frustoconical shaped outer surface of the housing to form a waterproof seal.

Abstract: An electrical box assembly includes a cover assembly, a gasket and an electrical box coupled together by mounting screws. The cover includes a base with a plurality of screw holes for receiving the mounting screws. A support member having an axial passage extends from the bottom face of the cover around each of the screw holes. The gasket includes a cylindrical shaped sleeve that passes through the support member and has an axial length to extend from the screw hole in the cover. The mounting screws are inserted through the axial passage of the sleeve and the screw holes in the cover to axially compress the sleeve to form a watertight seal between the screw shaft and the support member.

Abstract: A male plug of a single-pole electrical connector assembly includes a non-conductive housing and a conductive contact having first and second ends disposed in the housing. The first end is adapted to receive an electrical cable and the second end is adapted to engage a corresponding female contact. An axially extending slot is formed in the contact and extends toward the first end of the contact from the second end. The slot forms first and second slotted portions of the contact. A spring disposed proximal the second end of the contact substantially prevents yielding of the first and second slotted portions of the contact and biases the first and second slotted portions radially outwardly.

Abstract: A resectoscope with a working element and an electrode. The working element has a movable actuator assembly with a receiving area for receiving a proximal end of the electrode. The receiving area has an entrance, a plug area, and a curved section between the entrance and the plug area. The electrode has a proximal end with a connection section for connection to an electrical plug connector in the plug area. The proximal end also has a flexible section next to the connection section. The flexible section resiliently deforms along the curved section of the receiving area in the actuator assembly.

Abstract: A disconnectable electrical plug for use with a urological endscope comprising a housing; a conductor; a connector; and an extension block keyed for insertion into a guide block of the endoscope. The extension blocks extends from the housing at a substantially right angle to the entry of the conductor into the housing and is insertable into the guide block in either a first or second position. A urological endoscope is provided comprising a guide block with an electrical plug channel with a first entry on a first lateral side and a second entry on a second lateral side such that an electrical plug can be connected directly to an electrode by mounting the plug in the channel in either the first or second side of the guide block.
