Abstract
ABSTRACT
"A MAGAZINE FOR PLUG-IN ELECTRICAL ASSEMBLIES"
In a magazine for plug-in electrical assemblies having rear wall wiring, at the exposed ends of the contact pins (4) of the rear wall, cable plugs are attached to corresponding centering bodies (5) which serve to guide the ends of the contact pins (4) and are attached to support strips (7) spaced from the circuit board (3) forming the rear wall of the magazine.
The support strips (7) are provided with rows of closely adjacent support holes (12) through which the centering bodies (5) are screwed. In this way, it is possible to arrange the centering bodies (5) in a widely variable manner, so as to be closely adjacent to the magazine rear wall.

Description
1 1 7~7~
The present invention relates to a magazine for plug-in electrical assemblies which are connected to one another in the magazine by a rear wall wiring which comprises a printed circuit board snd contact pins which are connected by jumper wires.
It is known from German Patent Specification No. 27 43 428 as open to inspection, to attach a cable plug to the exposed ends of the contact pins for externally connecting the magazineO A centering , . . .
10 body for each particular plug is arranged between the exposed ends of the contact pins and the wiring space for the jumper wires. This centering body is placed over the contact pins and fixes the free ends thereof in the correct position. It is held at a 15 distance from the circuit board by means of spacing members. Ths centering body is attached by the spacing members to frame elements of the maga~ine which also carry the rear wall plug strips for the insertable C . assemblies. This means that each centering body is 2U assigned to a respective rear wall plug.
A magazine for electrical assemblies generally comprises at least-one printed circuit board which serves for the supply of a potential. This circuit board extends over and forms the whole of the rear wall.
25 In order for it to be possible to arrange a centering body at any desired position, the circuit board must possess a corresponding number of holes, in order , ~ ~767~
-- 3 ~
that the centering bodies may be screwed to the magazine frame. Since several rows of plugs can be arranged one above another in a magazine~ these holes throuyh which the securing screws are passed, are arranged not only in the edge zones but also in the centre of the circuit board. The large number of holes required limits the freedom of design of the circuit board with respect to the arrangement of the conductor - paths.
It is an object of the present invention to provide a magazine in which the attachment of the centering bodies is simplified and the number of through-holes required in the rear wall board for the passage of the securing screws is reduced.
According to the invention there is provided a magazine for plug-in electrical assemblies which are connected to one another by rear wall wiring which comprises a printed circuit board forming the rear `-~ wall of the magazine and contact pins connected by jumper wires ? onto the exposed ends of which pins at the rear face of the circuit board, one or more cable plugs can be attached for external connection purposes, wherein one or more centering bodies assigned to said plug or respective ones of said plugs is or are arranged between the exposed ends of the contact pins and the wiring space of the-jumper wires, the or each said centering body being positioned over the contact pin ends so as to hold the latter in ~ ~7~ ;0 the correct positinn and being attached to the magazine so as to be spaced from the rear face of the circuit board by means of one or more support strips attached to the magazine, the or each said support strip being provided with a series of holes into which the centering body or bodies is or are screwed.
The perforated strips require far fewer support points on the rear wall than would be needed if the centering bodies were directly attached thereto. The support strips are provided with support holes which may be arranged close to oné another in rows, the number of such holes considerably exceeding that of the suppor`t points. This means that the rear wall circuit board requires a considerably smaller number of openings for the attachmant of a support strip.
The support strips, which are attached so as to be spaced from the circuit board, are provided with closely adjacent holes, the spacing of which may correspond, for example, to one grid division of the rear wall contact pins. In this way, it is possible to arrange the centering body so as to be laterally offset relative to the rear wall plugs for the assemblies.
Installation of the centering bodies is also simplified since fewer spacing sleeves are needed and the centering bodies can be directly screwed to the support strips.
It is possible to use the same screws simultaneously to attach the support strip and the circuit board.

Consequently, no additional bores nePd to be provided in the circuit board for the attachment of the support strips.
It is further possible for a plurality of centering bodies, arranged one above another, to be attached by their adjacent ends to a common support strip. This reduces the number of support strips required and likewise the corresponding number of bores required in ~- the circuit boardO
The invention will now be further described with reference to the drawing, which is a schematic perspective view of one embodiment of the invention, The drawing shows a magazine for plug-in electrical assemblies 1 immediately prior to final assembly. The assemblies 1 can be connected by way of rear wall plugs 2 by rear wall wiring, the pins of the rear wall plugs being connected by jumper wires. This rear wall wiring comprises a printed circuit board 3 which - extends over and forms the whole of the rear wall of the magazine. Contact pins 4 of the rear wall plugs 2 project from the rear side of the printed circuit board 3. These contact pins can likewise be connected to one another by means of jumper wires. However, their length is such that cable plugs (not shown) can be attached to their exposed ends for the external connection of the assemblies. A centering body 5 can be positioned onto the exposed ends of the contact pins 4, ~ ~7~7~0 -- 6 ~
its function being to fix precisely the ends of the contact pins and mechanically secure the cable plug which is to be attached thereto. This centerlng body 5 can be secured to support strips 7 by means of screws 6.
These support strips 7 extend over the entire length of the rear wall of the magazine and can be attached thereto so as to be spaced from the circuit board 3, by means of further screws 8, which pass through securing holes 9 in the support strips 7 and through corresponding free bores l~ in the circuit board 3 and can be screwed to horizontal carriers ll of the magazine. Between the circuit board 3 and the support strips 7 spacer sleeves are arranged which ensure the spacing required for the wiring of the rear wall. The securing screws B thus serve simultaneously for attaching the circuit board 3 and the support strips 7.
The support strips 7 are each provided with a double row of closely adjacent support holes 12. By means of these holes, it is possible to attach ths centering bodies 5 variably and/or closely adjacent to the support strips 7. The securing screws S are preferably provided with self-tapping threads so that, - particularly when the number of centering bodies is small, relatively few support holes 12 need be provided with a thread.
