A seal assembly includes a circular resilient grommet-type seal having one or more through axial openings equal in number to the wires which pass through the seal and a rigid wire channel or guide which is received within a complementary pocket aligned with the seal between the seal and a reaction surface. The rigid wire channel or guide is retained in the pocket and carries any force exerted on the seal by pressure within the device to the aligned reaction surface. A method of installation includes the steps of mounting an electrical device within a component, routing the electrical wires leading from the device through an opening, routing the wires through corresponding openings in a grommet-type seal, pressing the seal into the opening, routing the wires through passageways in the rigid wire channel or guide and installing the guide in a complementary pocket which is aligned with the seal at one end and includes a reaction surface at the other end.

The invention relates to a method and to an apparatus for producing a plug-through connection arrangement of a plurality of electrical cables (1a-1d) and/or fluid-conducting hoses, having a sheathing (2) consisting of a plastic, which extend, arranged adjacently spaced apart from each other, through associated openings (3a-3d) of a plastic component (4), comprising the following steps: providing (A) the plastic part (4) with the pre-produced plurality of openings (3a-3d), installing (B) the electrical cables (1a-1d) and/or fluid-conducting hoses through the associated openings (3a-3d), such that the outer wall of the sheathing (2), which consists of plastic, comes into contact with the inner wall of the respective openings (3a-3d) of the plastic component (4), thermal welding (C) of the electrical cables (1a-1d) and/or fluid-conducting hoses to the plastic component (4) in the region of the respective opening (3a-3d), in order to produce an integrally sealing component bond, wherein at least two laser beam units (5a, 5b), positioned opposite each other, are aligned to an associated initial connection point, after which the oppositely positioned laser beam units (5a, 5b) are activated and caused to undergo a linear relative movement crosswise to the orientation of the openings (3a-3d), in order to create the integral bond by surface melting of the sheathing (2) together with the plastic component (4).

The invention relates to an assembly (14) of a cable-connecting device (10) and a multi-core cable (11), which form a mechanical, explosion-proof connection to each other. For this purpose, the cable-connecting device (10) has a plastically deformable outer sleeve (18) having a crimping section (23). A hollow cylindrical inner sleeve (19) made of elastically deformable material is arranged between a cable sheath (13) made of elastomer and the crimping section (23). An elastic deformation of the inner sleeve (19) and of the cable sheath (13) is caused by radially plastically deforming the crimping section (23). Any gaps (40) present within the cable sheath (13) are closed due to the radial forces in the crimping section (23) such that spark-gap-free contact between the cable sheath (13) and the cores (12) of the cable (11) and between the cable sheath (13) and the inner sleeve (19) is ensured.

It is an objective of the invention to provide a high-power supply cable characterized in that even when mounted in a narrow space where the cable undergoes a repetitive bending motion, any undesirable deformation out of the bending plane is small. There is provided a power-supply cable including: an electric wire including an electrical conductor and a resin sheath covering the electrical conductor, the electric wire having a tendency to generate a curl under a no-load condition, the curl having a curling direction, the curling direction being a normal to the curl, the electric wire having one or more longitudinal ends; a connecting terminal disposed at one of the longitudinal ends of the electric wire; and a curling tendency direction indicator showing the curling direction, the indicator being disposed along a normal line to the curl of the electric wire.

The invention relates to a cable clamping device, for example for an electrical connector, comprising at least one bushing and a clamping ring. The bushing and the clamping ring both comprise an opening for the passage of a cable. A bushing has a number of bushing portions which, joined together, form a sleeve about the cable. Two flanges bear the bushing portions and are articulated to a casing so as to pivot between an unclamped position of each bushing, in which the cable can be moved, and a clamped position, in which each bushing is kept clamped to the cable by the clamping ring. Locking means keep the clamping ring in the position in which the cable is clamped by the bushing.

An apparatus and method for preventing intrusion into a splice closure includes a pair of end wall plates, a first housing plate and a second housing plate affixed to an outer casing of the splice closure. Each end wall plate includes two or more end wall segments made of a formable metal and having a plurality of finger-shaped extensions that are bendable to conform to the contour of an end wall of the splice closure and around any cable(s) entering or exiting the splice closure. The first housing plate is made of a metal and pre-formed to conform to the contour of a first housing half of the outer casing of the splice closure. The second housing plate is made of a metal and pre-formed to conform to the contour of a second housing half of the outer casing of the splice closure. The first and second housing plates may be separable along a centerline of symmetry for use with an extended-length splice closure.
