Connection device and electrical tunnel installation
First Claim
1. A connection device for connecting a multicore branch line to a flat cable, comprising:
- a connection device housing that allows the flat cable to pass through;
penetration contacts for contacting the flat cable without stripping of the insulation, the penetration contacts being situated in the connection device housing;
an electrical disconnection point between the branch line and the flat cable;
at least one seal in an area of at least one opening of the connection device housing for protection from penetration of dust and/or water,wherein the connection device housing is made, at least partially, of plastic that includes polyethylene, andwherein the connection device housing on an outer side or an inner side is coated with a diffusion barrier layer, andwherein the diffusion barrier layer includes one or more layers, one of which is a metallic layer, wherein the metallic layer of the diffusion barrier layer comprises a vapor deposition of an aluminum film onto the outer side or the inner side of the housing of the connection device, wherein the layer thickness of the vapor deposition is a few nanometers to several hundred nanometers, and wherein the vapor deposition of the aluminum film is configured to prevent diffusion of vapor or liquid water molecules through the connection device housing.

Abstract
A connection device for connecting a multicore branch line to a flat cable has a connection device housing that allows the flat cable to pass through, and penetration contacts for contacting the flat cable without stripping of the insulation. The penetration contacts are situated in the connection device housing. The connection device also has an electrical disconnection point between the branch line and the flat cable, and at least one seal in the area of at least one opening of the connection device housing for protection from penetration of dust and/or water. The connection device housing is made, at least partially, of plastic, and on its outer side or inner side is coated with a diffusion barrier layer, wherein the diffusion barrier layer includes one or more layers, one of which is a metallic layer.
