Arrangement for connection of pipes
View Patent ↗An arrangement for connection of pipes includes a collar. In this case, the collar is provided for connection of the pipe ends of the pipes, and an earth connector is provided, by means of which the pipe ends can be electrically conductively connected. The earth connector is in this case in an integrated component of the collar, thus making it possible to make considerable savings in material and assembly effort, in comparison to known approaches. The arrangement results in a fluid-tight and electrically conductive connection of the pipes.
1. An arrangement for connection of pipes, having a collar for connection of associated pipe ends of the pipes and having an earth connector, by which the associated pipe ends can be electrically conductively connected to one another,
the earth connector being an integrated component of the collar,
the collar having at least two holding sections for fluid-tight holding of one each of the associated pipe ends,
the earth connector being arranged in one wall of the collar and being accessible only via cut-outs on the inside of the collar in the areas of the respective holding sections, the cut-outs exposing sections of the earth connector for making electrical contact with the respectively associated pipe end, in such a manner that plural edges of each cut-out area are sealed against outer circumferential surfaces of the pipe ends, in a fluid-tight manner, when the pipe ends are held in the holding sections.
2. The arrangement according to claim 1 , wherein the arrangement also has pipe clamping rings, by means of which the exposed sections of the earth connector can be pressed against the respective pipe outer walls of the associated pipe ends.
3. The arrangement according to claim 1 , wherein the associated pipe ends each have a circumferential bead, the exposed sections of the earth connector being arranged behind the respective bead relative to a transverse centre line of the collar.
4. The arrangement according to claim 1 , wherein end sections of the earth connector are looped around in the wall of the collar.
5. The arrangement according to claim 1 , wherein the earth connector is in the form of a strip.
6. The arrangement according to claim 1 , wherein the collar is made of an elastic plastic.
7. An arrangement for connection of pipes, comprising:
a collar for connection of associated pipe ends of the pipes, the collar having at least two holding sections for fluid-tight holding of one each of the associated pipe ends; and
an earth connector integrated into the collar, the earth connector arranged in a wall of the collar, and
wherein the wall of the collar includes cut out portions on the inside proximate to the respective holding sections, each cut out portion defining a channel, the cut out portions configured to expose sections of the earth connector for making electrical contact with the respectively associated pipe end, the exposed sections of the earth connector substantially completely occupying the channel, such that edges of each cut out portion are sealed against outer circumferential surfaces of the pipe ends in a fluid-tight manner when the pipe ends are disposed in the holding sections.
8. The arrangement according to claim 7 , further comprising a clamp that is isolated from the earth connector.
