DE3406385A1 - Mechanical security connection for electrical apparatuses - Google Patents

Abstract

In order to prevent undesired access to the power network, said network has previously been sealed using "blanking plugs". In consequence, simultaneous operation of electrical apparatuses on this network connection was precluded. The operation of an electrical apparatus with simultaneous protection against theft of the electrical apparatus being operated is ensured using a closed and mechanically secured plug connection which has a cable input supply whose size prevents withdrawal of the apparatus plug located in the plug connection. In order to make an attempt at theft more discernible, the security connection can be provided with an audible and/or visual signal which is triggered by the short-circuit current arising when the input supply mains cable is separated. Simple theft protection is thus achieved in that two mutually supplementary, mechanically connected and secured rigid parts have a network cable bushing for the apparatuses to be secured, whose size prevents separation of the electrical apparatus from the security connection.

Description

Mechanical safety connection for electrical devices

The invention relates to a mechanical safety association for Electrical devices according to the preamble of claim 1.

It is unknown to what extent these requirements have been met the technology is.

The invention is based on the object; on the one hand, the security connection should protect against unlanot removal of the electrical device to be secured and / or on the other hand the unwanted and unacceptable access to the power grid -in particular during the Operational or operational readiness - decrease.

These tasks are defined by the characterizing features of the claim 1 solved.

In order to prevent the theft of the electronic devices to be secured to counteract, with the features of claim 2, a further embodiment of the invention.

In order to easily secure theft protection of the To obtain electrical appliances, the safety connection is identified according to the part of the subclaims 3 formed.

Two embodiments are shown in the drawing and will be hereinafter referred to briefly.

As shows: Fig. 1 after the work paintings of the characterizing part of the Claims 1, pug. 1 a cable feed in the closed - with the dash-dot line -State shown and with the characterizing part of subclaim 2 pos. 2 the emergency switch, as well as pos. 3 the acoustic signal opening slots.

Fig. 2 according to the features of subclaim 5 pos. 4, the cable bushing.

The bore shown in Fig. 1 and Fig. 2 is used to receive a mechanical security (e.g. a cylinder lock).

Claims (3)

P a t e n t a n s p r ü c h e 1. Mechanical safety connection for electrical devices whose power cords are firmly anchored to the device, in particular for child and / or theft protection of the in operation or operational readiness (through network connection) located electrical devices. Characterized in that the socket (s) in the closed and secured state has a cable feed for the device to be secured whose Dimensions of pulling the device plug in the socket prevented. 2. Mechanical safety connection for electrical devices according to claim 1, d a d u r c h e k e n n n z e i c h n e t that on the one hand a network disconnection on the Cable - controlled by the short-circuit current generated for this disconnection process - and on the other hand, pressing the possibly built-in emergency switch (for interruption of the circuit) triggers an acoustic and / or optical signal. 3. Mechanical safety connection for electrical devices and their power cords are firmly anchored to the device, especially to prevent theft. Characterized in that at least two mechanically complementary connected and secured rigid parts a power cable bushing for the to be secured Has devices whose dimensions allow the electrical device to be disconnected from the safety connection prevented.
