A grommet assembly includes a wire harness and a grommet including a hollow channel configured to receive the wire harness therein. At least one rib extends inwards from and substantially annularly about the interior surface of the hollow channel. At least one port configured to fluidly couple the hollow channel with an exterior environment is defined by the grommet. Material is injected into the channel through the port to secure the grommet relative to the wire harness. The material injected into the channel flows through interstices located between adjacent wires that define the wire harness so as to encapsulate the wires. The injected material also flows into other voids and openings located within the hollow channel. Upon setting, the injected material is configured to prevent movement of the grommet relative to the wire harness and to prevent the passage of contaminants through the grommet assembly.

An electrical bushing is provided that includes a conductor, a conductive polymer screen, and an insulating body. The conductive polymer screen has a first region and a second region. The insulating body is molded over at least a portion of the conductor and is molded over the first region of the screen. The second region of the screen extends outward from the insulating body to define an exterior flange.

A wire harness assembly and a method of forming such a wire harness assembly is presented. The wire harness assembly includes a plurality of wire cables and a wire support defining elongate slots having open and closed ends. The cables are disposed within the slots. Retaining teeth are defined by side walls of the slots and are configured to separate one wire cable from another wire cable in the same slot. The wire harness assembly also includes a slug formed of a moldable material that encases the wire support. The slug also encases a portion of each of the wire cables. The wire harness assembly further includes a grommet encircling the slug. The slug may be formed by disposing the cables within the slots of the wire support, arranging the wire support and the cables in a mold, injecting a moldable material into the mold, and curing the moldable material.

A cable exit cover for sealing a portion of a cable includes a first cover member and a second cover member matable with the first cover member to define a housing having an inlet receiving the cable. The inlet has a sealing seat accommodating the cable. The sealing seat has a plurality of gripping devices uniformly distributing a dispensed sealing material along the sealing seat to seal a gap between the sealing seat and the cable.

A method of manufacturing a cable seal is provided, the method including the steps of providing a cable having a protective outer jacket of a non-PVC material; preparation of the protective outer jacket of the cable such as to promote adhesion with a sealant; and overmolding the outer jacket with a sealant. As a result, a sealing interface is formed between the jacket and the sealant.

An explosion-proof structure includes a partition wall that partitions a sealed space in a container and wiring that connects the interior and the exterior of the sealed space. The partition wall includes a filling portion through which the wiring passes. The filling portion includes an inner peripheral wall surface that defines an opening having a central axis that passes through the partition wall, a filler that seals a gap between the inner peripheral wall surface and the wiring, a first peripheral groove provided on the inner peripheral wall surface and filled with the filler, and a second peripheral groove provided on the inner peripheral wall surface and filled with the filler. This explosion-proof structure is capable of improving the seal of the filling portion.

A feed-through for high external pressure applications and methods of producing are provided. The feed-through includes a base body, a through-hole extending through the base body, and a functional element. The functional element is arranged inside the through-hole. The functional element is connected to the base body in fluid-tight manner with a pressure compensator and an insulating material that at least partially surrounds the functional element and establishes the fluid-tight connection. The pressure compensator increases pressure resistance of the fluid-tight connection of the functional element to the base body against pressure.
