Abstract: Aspects of the disclosure relate to a mantle terminal for establishing conducting contact, including a threaded stud for inserting a cable; a cap nut to be screwed onto the threaded stud; an insulating element inside which the cap nut is rotatably mounted and which includes a lateral plug portion; and a base plate on which the threaded stud is mounted and which includes a lateral receptacle for securely accommodating the lateral plug portion of the insulating element.

Abstract: A connector which can absorb thermal expansion and contraction of a substrate, or positional deviation of the substrate, and which enables the male and female connectors thereof to be fitted to each other where the male and female connectors are inclined to each other. A male terminal of a male connector, and a female terminal of a female connector are slidable relative to each other when in contact with each other. The male terminal and the female terminal are rotatable relative to each other about a contact point when in contact with each other, and hence the male terminal and the female terminal can be attached and detached to and from each other at an arbitrary rotating position.

Abstract: A connector comprises a sleeve and a rod, the threaded interfacing surface of one of the parts being provided with a longitudinal recess for the input of conductors. The recess has a concave surface facing the longitudinal axis of the connector and the depth thereof increases in the direction where the two parts are joined.
