Definitions
- the present invention relates to a method for connecting an electrical cable to an electrical equip ⁇ ment, the electrical cable being run to and mechani ⁇ cally connected to a cable attachment separable from the electrical equipment.
- the equipment which may comprise, for example, one or more circuit cards, is placed in a housing or box of insulating material or metal, the terminal block constituting the lid or the bottom of the box.
- the terminal block constituting the lid or the bottom of the box.
- bared cable parts can be inserted between two plates, whereupon a screw is tightened such that the upper plate is pressed against the bared cable part and the lower plate.
- This type of connection has the ad ⁇ vantage that a high and exact contact pressure can be achieved, and furthermore the same contact pressure is obtainable for all connections if the screws are tightened by means of a torque wrench.
- the terminal block and the electrical equipment separable in some simple manner.
- the block may constitute a bottom part to which the cables are permanently attached.
- the electrical equipment is then mechani ⁇ cally and electrically connected to the terminal block by means of plugs.
- connection technique has many advantages and, in fact, combines the advantages of the two above- mentioned connection techniques.
- a sufficiently high and exact contact pressure can be obtained since the electrical connection is established directly between the bared cable part and the electrical equip ⁇ ment.
- the equipment is readily accessible and replaceable since the mechanical separation also occurs directly between the bared cable parts and the electri ⁇ cal equipment.
- this connection technique is advantageous from the viewpoint of production en ⁇ gineering since the customer can acquire the standard attachments before the electrical equipment and there- fore can wire the entire cable system prior to installa ⁇ tion of the equipment.
- Fig. 1 is a cross-sectional view illustrating a method of making the connection according to the invention.
- Fig. 2 illustrates another method of making the connection according to the invention.
- FIG. 1 illustrates how a cable 1 is connected to an electrical equipment 2 identified hereinafter as the apparatus.
- the bared end 3 of the cable 1 is secured in an attachment member 4 on the upper side of an attachment 5.
- the apparatus 2 is mounted mechanically on the upper side of the attachment 5.
- Mounting is carried out in such a manner that an electri ⁇ cally conductive member 6, for example a plate, which is secured to the underside of the apparatus 2, is contacted with the bared end 3 of the cable 1.
- a screw 7 is used for urging " the plate 6 against the bared part 3 of the cable, whereby the desired contact pressure is established.
- the screw 7 may either extend through the plate 6 and down into the cable attachment 5 , thus contributing to the mechanical mounting of the apparatus 2 on the attachment 5, or it may only act upon the plate 6 from above, in which case the mechanical mounting must be accomplished for example by means of other screws (not shown).
- the Figure merely shows the connection of one cable to the electrical equipment, and it will be appreciated that in most practical instances a plurality of cables are connected in parallel to the illustrated cable 1 and on the opposite side of the cable attach ⁇ ment 5.
- FIG. 2 Another embodiment of the connection according to the invention is shown in Fig. 2 in which the com ⁇ ponent parts illustrated in Fig. 1 are identified by like numerals.
- the cable 1 is placed in a slit 9 and its end is introduced into an attachment member 4.
- the electrically conductive member 6 has a bulge which, when the appa ⁇ ratus 2 is mounted on the attachment 5 , extends down into the slit 9 and urges a bared part 3 of the cable against a plate 8.
- this may be provided with an electrically conductive contact safety device (not shown) which may consist of, for example, a U-shaped part which is secured over the bared part and against which the electrically conductive member 6 is urged when the apparatus is mounted on the attach- ment.
- an electrically conductive contact safety device (not shown) which may consist of, for example, a U-shaped part which is secured over the bared part and against which the electrically conductive member 6 is urged when the apparatus is mounted on the attach- ment.
- the attachment 5 may constitute instead a lid, to the underside of which the cable 1 is attached and the apparatus is mounted.
- the electri ⁇ cally conductive member 6 of the apparatus, as well as the attachment member 4 may be designed in different ways, and the cable can be attached by pushing it down into and at right angles to the upper side of the attachment.

Abstract
Un procédé permet de connecter un câble électrique (1) à un équipement électrique (2). Le câble électrique s'étend jusqu'à une fixation de câble (5) et y est mécaniquement connecté. L'équipement électrique (2) et la fixation de câble (5) sont mécaniquement interconnectés, de sorte qu'un organe électriquement conducteur (6), qui fait partie de l'équipement électrique, exerce une force sur la partie dénudée (3) du câble (1) qui s'étend jusqu'à la fixation, en établissant ainsi un contact électrique entre l'organe électriquement conducteur (6) et la partie dénudée (3).A method makes it possible to connect an electrical cable (1) to electrical equipment (2). The electric cable extends to a cable fixing (5) and is mechanically connected to it. The electrical equipment (2) and the cable fixing (5) are mechanically interconnected, so that an electrically conductive member (6), which is part of the electrical equipment, exerts a force on the stripped part (3) of the cable (1) which extends to the fixing, thereby establishing an electrical contact between the electrically conductive member (6) and the stripped part (3).
