Connector
In a connector, a tapered portion is formed at a corner portion between a housing and a flange portion so as to be formed in parallel to a chamfered portion formed on an edge of a mounting hole in a casing. An annular seal member of the connector is mounted on an outer peripheral surface of the housing at a front side of the flange portion in an insertion direction of the housing, and is brought into close contact with an outer peripheral surface of the housing and an inner peripheral surface of the mounting hole so as to seal therebetween. A lip portion abutting on the flange portion is provided on a rear side of the seal member in the insertion direction. An outer peripheral surface and an inner peripheral surface of the lip portion are formed in parallel to the tapered portion.
Insulation termination assembly
An insulation termination assembly comprises an insulation tube, an annular bottom plate, and a tail assembly. The insulation tube has an inlet end, an outlet end opposite to the inlet end, and an inner space filled with an insulation liquid. The annular bottom plate is mounted at the inlet end of the insulation tube. The tail assembly comprises an insulation connection tube mounted on the annular bottom plate and a shield tail tube connected to the insulation connection tube. A cable joint of a cable is introduced into the inner space of the insulation tube from the inlet end of the insulation tube after passing through the shield tail tube and the insulation connection tube.

Method of manufacturing a cold shrinkable termination and assembly
A method of manufacturing a cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. An electric power cable is provided having an exposed end including: a conductor core having an exposed portion and an unexposed portion; an insulation layer having an exposed portion and an unexposed portion covering the unexposed portion of conductor core; a semi-conductive shield layer having an exposed portion and an unexposed portion covering the unexposed portion of the insulation layer; a metal shield layer having an exposed portion and an unexposed portion covering the unexposed portion of the semi-conductive shield layer; and an outer protection layer covering the unexposed portion of the metal shield layer. A cold shrinkable termination is provided including: an insulation tube; a stress control glue; and, a support tube. The stress control glue is coated along a selected segment of an inner wall of the insulation tube. The insulation tube of the cold shrinkable termination is expanded on the support tube. The exposed end of the electric power cable is inserted into the support tube, and the support tube is removed from the insulation tube such that the insulation tube shrinks on the exposed end of the electric power cable. Thereby, the structure of the cold shrinkable termination is simplified and the cost thereof is reduced.
Electromagnetic Shielding
A cable bushing is disclosed for placement into a control housing surrounding a printed circuit board that is provided with a bushing housing, comprising a locating surface, fasteners for fastening the bushing housing to the control housing, and retainers for at least two cables that are to be electrically connected to the printed circuit board. To facilitate the assembly of the cable bushing, a shielding plate is provided which embodies a shielding surface for contacting a shielding on the control housing side. The shielding surface is connected to a contact surface in an electrically conductive manner, and is exposed at a back of the bushing housing facing away from the locating surface to be connected to a shielding

Electric field control device for high power cable and method for manufacturing thereof
An electric field control device for a high voltage cable includes a stress cone and a field grading adapter, wherein the stress cone and the field grading adapter are chemically bonded by vulcanization. An electric installation includes a power cable and the electric field control device. A method for producing the electric field control device is also disclosed.

Cold shrinkable termination, cold shrinkable termination assembly and method for manufacturing the same
A cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. When the cold shrinkable termination is mounted on the electric power cable, the stress control glue fills a gap between the electric power cable and the insulation tube so as to prevent local electric field concentration from occurring at an exposed end of the electric power cable. The stress control glue has a dielectric constant within a range of 5 to 100. In this cold shrinkable termination, a stress control glue with high dielectric constant is provided to optimize the electric-field distribution on an insulation surface of the electric power cable. Thereby, the structure of the cold shrinkable termination is simplified and the cost thereof is reduced. The cold shrinkable termination may be adapted to an electric power cable used to transmit voltage less than 26/35 kV.
Terminal fitting fixing structure and wire harness
A terminal fitting includes a cylindrical portion having a first crimping region and a second crimping region. A crimped state of a braided body extending through the terminal fitting is formed between the terminal fitting and a cable at the first crimping region such that relative movements of the terminal fitting and the braided body are prevented, and an end of the braided body is then folded back and positioned to face an outer surface of the cylindrical portion in a radial direction. The crimped state of the braided body is then formed between a sleeve and the terminal fitting at the second crimping region, so that the terminal fitting is fixed to the braided body.
