Abstract: A cable connector includes a soft body. The soft body has at least one connecting portion. An outer wall surface of the connecting portion is provided with a hard casing. The soft body is made of a soft material, such as rubber and silicone rubber. The hard casing is made of a hard material, such as plastic, and has higher rigidity than the soft body. When a bushing of a cable is inserted into the connecting groove of the connecting portion, the hard casing is configured to resist deformation, so that the connecting portion will not be deformed by insertion of the bushing, thereby improving the electrical connection between the cable connector and the bushing.

Abstract: A connector assembly applied to a high-voltage interface includes a first connector and a second connector to be connected to each other. The first connector has an accommodating groove. A socket is provided in the accommodating groove. The socket has an electrical connection hole, an elastic holding portion, and a first engaging portion. The second connector has a plug-in portion corresponding to the accommodating groove. The plug-in portion is provided with a conductive probe corresponding to the electrical connection hole and a second engaging portion corresponding to the first engaging portion. The accommodating groove, the electrical connection hole, the plug-in portion and the conductive probe are all parallel to the same axis, so that the first connector and the second connector are connected to each other in a sliding manner.

Abstract: A pre-bracing tube of a cold shrinking sleeve includes a tubular body made integrally of plastic. The tubular body has its outer circumferential wall forming a spiral and successive tearing groove and a spiral and successive belt body between every two tearing grooves when the tubular body is shaped. Thus, when the tubular body is torn along the tearing grooves, the belt bodies can be drawn and takes advantage of an opportunity to draw the torn portion out of the tubular body. The tearing groove of the tubular body is formed when the tubular body is injection molded so it is needless to carry out any processing to the tubular body for obtaining a finished product, easy in manufacturing, convenient in production and able to lower cost. In addition, various molds can be made for matching with requirements of different diameters or lengths.
