Description

.8004232-8 10 15 20 25 30 35 2 facing downwards U, whose flanges 14, 15 form a right angle with the rail 10 and whose web 16 forms a right angle with the flanges 14, 15. From the end portions 11, 12 a leg protrudes 17 and 19, respectively, which extends in the same plane as the portions 11, 12 and has an outwardly curved end 18 and 20, respectively.

From the legs 14, 15 of the U-shaped portions 13 also protrude legs 21 and 23, respectively, the legs 21, 23 belonging to each portion 13 diverging in the direction from the portion 13 and having curved ends towards each other. The legs 21, 23 are, as shown at 25, 26, knocked out of the material of the rail 10 and the legs 14, 15, respectively. From the above it appears that all the parts of the earthenware are made of one piece and that the end portions 11, 12 and the portions 13 located therebetween divide the rail 10 into three equal parts, each of which is assigned its own outlet at the branch socket. The legs 17, 21 and 23, 21 and 23, 19, respectively, associated with each socket with mutually curved ends 18, 22 and 24, 22 and 24, 20, respectively, form the ground rails, with which the ground rails on a grounded socket are intended to engage when inserting the plug in the branch socket. The rail 10 is of course made of conductive material and the legs 17, 21; 23, 21; 23, 19 are arranged to spring slightly apart during the engagement with the ground rails of the plug, when this is inserted into the socket. The portions 13 have the advantage that the legs 21, 23 can be knocked out of the rail material despite the limited length of the rail 10. The height of the portions 13 above the rail 10 also enables so-called peg protection to be placed between adjacent legs 18, 21; 23, 21; 23, 19 to prevent accidental contact with live parts through the branch socket openings. In this way, the earthenware can also be mounted in a very simple way in a socket-protected branch socket.

The invention has been described with reference to a branch socket with three sockets, but it will be understood that the principle of the invention is also applicable to wall or branch sockets with more or fewer sockets. The grounding device can be manufactured 8004232-8 3 in a very simple manner by a punching and bending operation and although it is much cheaper than hitherto existing grounding devices of this type, it is much safer due to the fact that play cannot occur and enables 5 in addition, easy assembly.

800l | 232 ~ 8 10 15 20 4 PATENTKRAV Grounding devices, in particular for so-called socket-protective wall and branch sockets, with spaced apart, unobstructed legs (17, 21), which are of conductive material and resiliently separable for engagement with ground rails on opposite sides of a socket and which are connected to a holding rail (10), also of conductive material, which in turn is connected to a ground wire, characterized in that the legs (17, 21) and the holding rail (10) are formed in one piece , that the holding rail has upwardly bent portions (11, 14), from which the legs (17, 21) originate, and that at least one leg (21) is knocked out of the material of the holding rail (10) and associated upwardly bent portion (14). Grounding device according to Claim 1 for wall or branch sockets down several sockets, characterized in that the holding rail (10) has at least one part (13) bent upwards and downwards, the U-flanges (14, 15) forms said upwardly bent portion for the adjacent legs (21, 23) of or the branch socket. 4 Grounding device according to claim 1 or 2, characterized in that the space between said upwardly bent portions (ll, 14) is dimensioned for receiving a so-called protection. two adjacent sockets in the wall
