  • Patent number: 11942233
    Abstract: A fire resistant corrugated coaxial cable is described that employs a high-temperature, insulating alkaline earth silicate (AES) wool dielectric. The AES wool dielectric is devoid of water as a constituent. The AES wool may be survivable under conditions of high heat, such as temperatures specified by common fire test standards (e.g., 1850° F./1010° C. for two hours). The cable is configured to maintain a relatively coaxial relation between a center conductor and an outer conductor even under aforementioned fire tests. A layer of ceramifiable silicone rubber or refractory fiber wrap can surround the outer conductor and continues to insulate it from the outside if a low-smoke zero-halogen (LSZH) jacket burns away.

  • Patent number: 11936152
    Abstract: A method is provided for electrically conductively connecting a contact part to a conductor having a multiplicity of individual wires includes inserting the conductor into a cavity in the contact part and lowering a tool for friction stir welding onto the contact part. The tool for friction stir welding is moved on the contact part in a plane, thus giving rise to a planar cohesive connection between the contact part and the conductor. In this way, a direct cohesive connection of a stranded conductor and a contact part is produced without the need for an additional part such as a sleeve, for example, to prevent the stranded conductor from “sticking out”.

  • Patent number: 11909153
    Abstract: A safety cap device includes a flexible cylindrical cap formed of material of low conductivity such as rubber. Additionally, the device includes a spring biased clip is integrated on the open end of the cap such that the clip is used to clip about a wire and hold the cap over the end of said wire. In one embodiment, the clip retains the cap in a closed position by the tension of the spring in its relaxed stated. The clip is then compressed which then in turn compresses the spring to engage the cap in an open position. The cap is then mounted onto exposed electrical wiring which will provide protection to a user working with the exposed wiring. A user utilizes the cap as a handle which prevents direct contact with the exposed wiring.
