Abstract: A shrinkable protection element for covering filiform items, such as a joint between electrical cables. The element comprises a first (2) and second (3) sleeve, the second sleeve being coaxially superimposed upon the first one. Both sleeves are elastically expandable in a radial direction, i.e. shrinkable. The first sleeve is made up of a compound of cross-linked polymeric material including a peroxide curable hydrocarbon terpolyme of ethylene, propylene and a non conjugated dilene EPDM material, while the second sleeve is made of sulfur-cured EPDM material. As a result, the shrinking speed of the second sleeve (3) is higher than that of the first sleeve (2), especially at temperatures between 0.degree. C. and 40.degree. C. The cables may thereby be used about 30 minutes after the installation of the protection element thereon.

Abstract: A pre-assembled electrical splice component for splicing electrical cables of the type including a central conductor, an insulative layer, a conductive shield, and an outer protective jacket. The pre-assembled splice component includes a radially collapsible support core, upon which is positioned on a conductive sleeve. At least one spring is positioned over the conductive sleeve and compresses the sleeve against support core. When the support core is removed the spring constricts to a reduced diameter and thereby compress the conductive sleeve against a conductive shield of the cable. Additional layers of material may be placed on the support core for providing electrical insulation or shielding.

Abstract: An insulator (100) wherein a funnel portion (120) has a conical inner peripheral surface (121) of an inner diameter increasing in a direction away from a body (101). A male terminal (second terminal) (161) is inserted into the insulator (100) from the funnel portion (120) to mate with a female terminal (first terminal) (151) housed in the insulator (100), and a jig (170) is prevented from interfering with an edge of the funnel portion (120) of the insulator (100) as the male terminal (161) is securely pushed into the female terminal (151), thereby preventing connection failure between the first and second terminals.

Abstract: An electric power cable line is arranged in which the insulating layer is increased to a greater thickness at two end portions of each cable than a thickness at the other or center portion of the same. Since the insulating layer is increased in thickness at the end portions of the cable, thus an electrical stress exerted on the overall layer construction of the end portions is lowered. Hence, the dielectric strength of the end portions of the cable becomes high and the power cable line will thus be increased in the operational reliability.

Abstract: Electro-static discharge is a problem with high-speed data even when using coaxial cables. Primarily, this problem arises at the terminal ends of the circuit where connections are made using separate coaxial cables for connecting to various pieces of equipment thereby allowing voltages to be induced differently in each such cable. This problem can be overcome by combining a portion of each cable such that the shield around each signal carrying wire remains intact while also being solidly in contact with the shield from the other wire. The cable is constructed by removing the outer insulation from a section of two single coaxial cables, electrically connecting together the exposed shields of each cable at both ends of the exposed section and reinsulating the abutted cables so that the shields remain in contact along their entire length.
