Description

Cable coupling for manual or automatic operation, especially on rail vehicles

Field of application of the invention

The invention relates to a cable coupling for manual or automatic operation in particular on rail vehicles with main contacts for switching through the lines and switch contacts for auxiliary switching purposes, the main and / or switch contacts are housed in frontal bores of the front insulating contact support plate each cable coupling half ·

Characteristic of the known technical solutions

Switching contacts for electrical cable couplings are required for various special purposes. As opener, closer or switch so that the control lines are durchgekuppelt or adjacent lines within the own coupling half connected or disconnected · It dependencies of control circuits of contactors are provided by the coupling process · For example, in this way Zugschloßschleifen, lock or indicator lights are switched Switching contacts are generally mechanical contacts and usually designed as auxiliary switching contacts of the main contacts · A snap action of the auxiliary switch contacts, especially in automatic couplings, not necessary because the coupling process occurs abruptly · On the other hand, there is nothing wrong with a snap behavior ·

In the process, the pressure contact against the spring force is pushed back during the coupling process. Sr thereby moves a contact arm, which is perpendicular to the coupling axis, which corresponds to a contact arm of a fixed contact next to it. h · acts as an opener or closer with this (DE-OS 2,941,482).

While the main contacts, such as pressure, fixed or plug contacts, are accessible from the front and allow a contact surface cleaning, the switching or auxiliary contacts are further back, but also unprotected inside the coupling head · They are practically inaccessible for Xeinigungsarbeiten · The occurring in railway operations very Heavy soiling often causes failures, especially at low operating voltages and low currents.

Aim of the Ξ £ £ ind ind

This object is achieved in that are used as switching contacts so-called Heedkontakte use that these form fit the main contact dimensions accommodated in the holes of the contact carrier plate and switchable by associated magnetic fields, which are applied or influenced by the counter-coupling half during the coupling process.

Effects of contamination of any kind on the function of the switching contacts are completely avoided in this way · Magnetic premodern influences of the contacts have not been observed so far.

Each Reed contact, possibly also several together, a Setätigungsmagnet is assigned to the mating coupling half.

As actuation magnets, permanent magnets are preferably provided ·

The associated permanent magnets and Eeedkontakte are each housed in special corresponding main contacts ·

It is advantageous that the permanent magnet annularly surrounds one or more reed contacts, and that the shielding plates of the gene genkupplungshälf te engage in grooves between the permanent magnets and the reed contact.

The Heed contact can be useful actuated by a arranged on the cover of the own Kupplungshälcfte permanent magnet in their movement during the coupling process.

3s is also possible that the reed contact can be actuated by a shielding plate arranged on the cover flap of its own coupling half during its movement during the coupling process.
