Abstract

The invention relates to a cable lug for connecting a cable end to a screw type terminal. The cable lug comprises a flat, u-shaped contact fork which is open toward the front and which merges into a fork shaft toward the rear. The fork shaft is provided with connection means for a cable end. At least one base plate configured as a signal conductor, at least one damping disk made of elastic material, and at least one cover plate are assembled in a stacked, sandwich-like manner in the area of the contact fork. In order to improve functional characteristics and durability, and more particularly to obtain an improved vibration-damping action, the invention provides that the cover plate extends over the sides of the damping disk.

Claims

1. A cable lug for connecting an end of a cable to a screw-type terminal, comprising a flat contact fork which is open in the form of a “

U”

toward a front end, and which changes into a fork shaft toward a rear end, said fork shaft comprising a connecting means for connecting the end of the cable, at least one base plate configured as a signal conductor, at least one damping disk made of elastically deformable material, and at least one cover plate are stacked within the area of the contact fork, wherein the cover plate (7) extends over the sides of the damping disk (8).

2. The cable lug according to claim 1, wherein within the area of the contact fork (2) the cover plate (7) has a downwardly projecting side wall (7a) extending all around along its outer contour and reaching over the damping disk (8) up to the base plate (6).

3. The cable lug according to claim 2, wherein the base plate (6) comprises a piston, immersible from below in the space limited laterally and at the top by the cover plate (7).

4. The cable lug according to claim 2, wherein within the area of the contact fork (2), the base plate (6) is provided with a step along the upper edge.

5. The cable lug according to claim 1, wherein the cover plate (7) comprises a spring-elastic material and is permanently joined with the fork shaft (3) behind the U-shaped contact surfaces.

6. The cable lug according to claim 1, wherein the cover plate (7) comprises a hardened, heat-treated steel sheet material.

7. The cable lug according to claim 1, wherein the cover plate (7) comprises plastic.

8. The cable lug according to claim 1, wherein the cover plate (7) further comprises stop elements being supportable against the base plate (6).

9. The cable lug according to claim 1, wherein the damping disk (8) comprises elastomer material.

10. The cable lug according to claim 1, wherein one of the following cover plate (7) and the damping disk (8) and the base plate (6) have hydraulic compensation cavities (9) for the elastic material of the damping disk (8).

11. The cable lug according to claim 1, wherein the cover plate (7) has form-locked elements engaging the damping disk (8).

12. The cable lug according to claim 1, wherein the base plate (6) and the fork shaft (3) forming one single piece comprise highly conductive material.
