DE2608129A1 - Keying for correct fitting of subunits - has keys which may be repositioned to allow fitting of differing units - Google Patents

Abstract

Keying system preventing the fitting of incorrect units or to ensure the exact positioning of a unit or sub-unit with respect to some other unit. The design allows the key to be altered such that a different unit may be installed if required. The keying arrangement is based on the fitting of two or more keys (2) into the platform of the main unit (1) or chassis, each key having a short spindle (3) locating with holes in the base of the unit (5) to be fitted. Each such key is square or hexagonal in section with the spindle offset from its center. The key is a permanent magnet and the base (6) of its socket is of some ferromagnetic material.

Description

klschluss - plug-in base with pre-settable device for device allocation The invention relates to a connector socket, in particular for use in small distributors, for connecting various devices with a pre-adjustable device for a one-to-one assignment of the plug-in base to the device.

Due to the separation options, connection plug-in bases offer between Base and device to be plugged in, great advantages for wiring, assembly, maintenance, Troubleshooting and repair.

In addition, the use of plug-in bases enables very universal modular construction Constructions. Standard plug-in bases for various devices, individual plug-in bases for only one specific device at a time, as well as standard sockets that are used for the respective Device adaptable are known in various embodiments. For adaptable Connection sockets are systems with empty sockets, with full sockets and with mating pins known. It is evident that it is disadvantageous that in most cases under tension standing system must be manipulated and through wrong wiring or wrong Plugged full sockets or mating pins pose a risk from contact voltages may exist.

The invention is based on the object of a connector socket to find a reversible unique assignment between the respective socket and associated device made possible by a simple adjustable device, wherein on the electrical plug-in part, i.e. on sockets and plug pins or blades No changes may be made for security reasons.

According to the invention, this object is achieved by eating prisms Pins eccentrically arranged in the direction of the prism axis for various devices different positions in prism-shaped recesses in the socket can be plugged in and fixed there, with the associated devices in the rear Recesses are provided for inserting the pins.

According to a further feature of the invention, the prisms are square or hexagon.

Another feature of the invention is that a prism or several pins are arranged.

According to an additional embodiment of the invention, the to Prisms arranged pins formed as cylinders or prisms.

Another inventive feature is that the prisms from permanent magnetic material.

As an inventive feature is also provided that in the base of the prismatic recess of the base is permanent-magnetic Insert is embedded.

An embodiment of the invention is shown in the drawing and is described in more detail below.

The figures show: FIG. 1 a cross section through a connection plug-in base with device.

Fig. 2 shows two examples of a socket pin.

In Fig. 1 is the cross section leading through the socket pins represented by a connection plug-in base with attached associated device. Two recesses let into the socket 1 are used to receive the socket pins 2, the eccentric pins 3 in corresponding recesses in the bottom plate 4 of the inserted device 5 protrude. The socket pins 2 are replaced by an in the recesses of the Socket 1 inserted magnetic plate 6 held.

Due to the eccentricity of the pins 3 and the various options for inserting them of the prismatic part of the socket pin 2 in the socket 1 and through the number of socket pins used is a wide range of Allocation options of devices to the connection sockets are given.

In Fig. 2 is a socket pin 2 with a square and a hexagonal body shown.

The advantages achieved with the invention are in particular: that, for example in small distributors, connection sockets are fully wired can, with the assignment of the devices to be plugged in through the socket pins can be done by assembly. Since the blocking is purely mechanical, it is electrotechnical Optimal security.

It is also advantageous that the solution according to the invention with simple Means a very wide variable range of combinations between bases and assignable Devices.
