Description

GERMAN

In many cases it is required to be exposed as well thus accessible wire ends, which are fixed by screws, to prevent unauthorized loosening protection. In the known types of fastening by screws, the end of the wire is bent into an eyelet and guided through the resulting opening of the shaft of a screw, which is inserted into a thread of a washer intervenes. The wire eyelet is thus located between this pad and the screw head and is thereby stuck. The end of the wire can also be loosened by loosening the screw. The end of the wire but can also be loosened without loosening the screw by removing the end of the wire eyelet is simply bent open with suitable tools and out of the clamp seat between the base and Screw head is pulled out. The end of the wire can then also be removed without operating the screw simply place it around the screw shaft between the screw head and the base and insert it into the pinch the previous position.

Means are already known for relative rotation of the nut in nuts provided with bolts to prevent screw. The mother has a special training and works with you Wire ring that is anchored in the pad. These known means are used as a safety device Unsuitable for wire ends fixed by screws to prevent unauthorized loosening.

The invention relates to a safety device for wire ends fixed by screws, which prevents unauthorized loosening of the wire ends. The invention consists in that a with the Screw fastened angle is used, the leg resting on the base in itself is provided in a known manner with a hole for a sealing screw and its perpendicular thereto standing leg has at least one bore that the elongated ends of the resulting Wire eyelet takes up, while a sealing wire through the same or another hole in this eye leg connected to the screw and sealed.

In the drawing, an embodiment according to the invention is shown in three views and is explained in more detail below. The same elements have the same reference symbols.

The wire end to be protected against unauthorized loosening is denoted by 1. This is by one Screw 2 clamped on the base 3. A washer 4 can also be installed in front of the safety device for secure clamping
