Description

Description:

The invention relates to an electrical connection and distribution device, in particular for installation in or on moving machines, units and

Vehicles.

So far, as electrical connection and distribution devices, especially in vehicle construction, the well-known junction boxes

used, which are mostly made of plastic and essentially box-shaped with flat lid are formed. The lid is mostly on the box by means of arranged in the corners Screws fastened, with between cover

and box a seal is inserted. Often, however, this inserted seal cannot be complete Ensure that the interior of the box is sealed because of the low inherent rigidity of the flat lid and the tension caused by the tightened screws often warps them, the seal However, this is only possible with a completely flat cover.

A contact strip is regularly attached to the floor inside the distribution box, to which a plurality of contact tabs or bridges

are arranged and to which the individual cable ends are screwed. The individual in the Lines ending in distribution boxes are led through passages provided in the box side walls and sealed within it.

The correct installation of the lines and line connections within the switch box requires the use of a specialist, ¹ under no circumstances can a layperson who is not trained in this field carry out the corresponding work.

The object of the invention is to create an electrical connection and distribution device which is structurally much more compact than the conventional junction boxes, with one Complete electrical isolation of the individual electrical components from one another and protection offers against penetrating dirt and the associated corrosion and is particularly suitable that Record the desired electrical connections pre-programmed and during final assembly the machines, units and vehicles in question from not in the electrical field trained persons can be installed and connected.

This object is achieved in that an electrical

see connection and distribution device of the introduction mentioned type essentially electrical connection devices for external lines, these Connection devices electrically interconnecting conductor devices, the electrical conductor devices mutually shielding insulators and one, the connection devices, the Conductor devices and the insulators physically connecting to one another without substantial gaps summarizing as well as electrical

having insulating and protective surrounding envelope.

Compared to the known distribution boxes, this device according to the invention is much more compact Construction method, in particular it does not offer any air-filled spaces into which through poorly Seated or incompletely sealing seals Dirt penetration and corrosion on the metal parts Hervoi- "can be called.

Each connection device advantageously consists essentially of a cylindrical one Socket with a base bottom, through which contact pins are axially passed.

The socket-shaped design of the connection devices allows easy plugging and insertion

the end parts of the external lines to be connected. Due to the special arrangement of the contact pins or Arrangement of centering devices can provide unchangeable positioning within each connecting device can be set in a simple manner.

The contact pins are advantageously fastened on or on the conductor devices in an electrically conductive manner. This ensures that between the contact pins on the one hand and the conductor devices on the other

on the other hand, no additional, conductive connecting means need to be arranged, which special electrical Make installation work necessary.

According to the invention, the conductor devices are as formed thin metal plates in which recesses are partially provided through which parts of the Connection devices, in particular contact pins, are passed through in an isolated manner.

This formation of the conductor devices enables the desired circuits to be finalized and the individual contact pins can be assigned to the respective metal plates.

The conductor devices are advantageously designed as stamped circuits. In other more advantageous These ladder devices can also be trained as

printed circuits can be formed on printed circuit boards.

In a further training according to the invention are the Iso arranged between the ladder devices

lators designed as plates made of insulating material and their external dimensions are smaller than those of the ladder devices, but no more than the same size.

The aforementioned plate-shaped design of the Isola

gates allows a parallel and alternating arrangement of conductor devices and insulators, so that several Head devices used insulated from each other and on these the respective necessary contact pins can be arranged, with the conductor

Devices should not protrude beyond the dimensions of the isolators.

The sockets advantageously have their cylindrical ones Outer walls on guides, which in the manner of a

Bayonet lock are formed and the correspondingly formed locking caps external Include connecting cables.

This design of the sockets allows a sealing and the connection lines in the connection devices firmly holding connection of the external electrical lines, whereby the assembly itself in one

can be carried out in the most professional manner by untrained personnel.

According to the invention, the casing is a one-piece Housing formed, which at the same time the book

sen and forms their base floors.

This training enables the conductor devices, contact pins and insulators to be complete and seamless and thus protected against corrosion, can be encapsulated with plastic.

In an advantageous embodiment, the envelope can be designed as a two-part housing, its dividing joint is arranged in a plane perpendicular to the contact pins, each housing

seteil forms the respective sockets and their base bases on one side of the housing.

In another advantageous embodiment, the envelope can be designed as a two-shell housing, which are the conductor devices and the insulators

encloses and wherein, recesses in each shell half are provided, in which the connection devices designed as individual components can be used are.

An exemplary embodiment which does not limit the invention is shown in the drawings.

Devices and isolators 17, 18 and 19, respectively embraces and holds them together without substantial gaps.

Both the conductor devices 14, 15 and 16 as well as the insulators 17, 18 and 19 are essentially designed as rectangular plates of different thicknesses and arranged alternately one behind the other. Here, the insulators protrude beyond the individual conductor devices within their dimensions,

wherein the conductor devices in, their dimensions and thicknesses corresponding recesses of the insulators are inserted.

On the ladder devices 14, 15 and 16 are each

according to the intended circuit and assignment, individual contact pins 20 of the individual connection devices 4, 5, 6, 7, 8, 9 or 10 arranged, the contact pins are aligned perpendicular to the plane of the individual conductor devices. In case that a contact pin 20 'is attached to a conductor device 15, which is from another conductor device 14 is covered, there is a corresponding recess in the covering conductor device 14 provided for the contact pin 20 '.

The ladder devices illustrated in Figure 4 are
