Embodiment Construction

[0019] Shown here is a terminal box 1 with an internal terminal strip 1b, a terminal box opening 2, a threaded hole 3, a front panel 1a partially realized by the surface of the terminal box, and a middle part 4 with a middle part opening 5 and the thread 5a provided in the opening 5 of the middle piece and the hole 5b for receiving the fastening bolt and the plurality of fastening bolts 6 . The figure also shows two cables 7 with threaded fasteners 8 and cable harness 9 . When the device is delivered, the terminal box 1 is usually already screwed onto the device to be electrically connected. If you want to remove the junction box from the device, you must first remove the bolts. There are also some junction boxes 1 that are not detachably connected to the equipment casing.

[0020] To reinforce the outer walls of the junction box, plates 1a are cast onto the side of the junction box. The plate 1a comprises at least four threaded holes for bolts 6 in order to be able to scre...

Abstract

The box (1) has an intermediate piece (4) comprising an opening (5), and detachably arranged on the box by a retaining unit (6), so that a terminal box inner space is accessible from outside the box by the opening of the intermediate piece. The intermediate piece comprises a screw thread (5a) in order to fasten a cable (7) to the piece, so that the cable is guided through the opening. The piece forms a part of a terminal box surface, and is realized as a plug-in board, which is moved parallel to the surface. An independent claim is also included for a method for connecting a cable to a terminal box.

Description

technical field [0001] The present invention relates to a junction box for electrical system connections and a method of establishing connections. Background technique [0002] Junction boxes are well known in the prior art, and such junction boxes generally comprise cable terminals to which cables are led from the outside of the box. The role of the terminal block is to interface with the electrical system. Since the junction box is usually installed directly on the electrical machine, such as an electric motor, it is in a very unfavorable working environment in most cases. Therefore, the junction box usually must be protected against splashing water, and even needs to be sealed against water. Furthermore, an oil-proof, acid-proof and so-called explosion-proof construction is often required. [0003] For example, German Patent DE 4225148A1 describes a junction box similar to Japanese Patent Publication JP 04364338A. There are some features in the latest proposed patent ...
