Embodiment Construction

[0019] Shown here is a junction box 1, a junction box opening 2, a threaded hole 3, a front panel 1a partially realized by the surface of the junction box, and an intermediate piece 4 with a terminal strip 1b inside, the intermediate piece 4 having an intermediate piece opening 5 and a thread 5a provided in the opening 5 of the intermediate piece and a hole 5b for accommodating a fastening bolt and a plurality of fastening bolts 6. The figure also shows two cables 7 with threaded fasteners 8 and cable bundles 9. When the equipment is delivered, the junction box 1 is usually screwed onto the equipment 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 housing.

[0020] In order to reinforce the outer wall of the junction box, the plate 1a is cast on the side of the junction box. The plate 1a includes at least four threaded holes...

Abstract

The present invention relates to a terminal board used for terminal box. The terminal box used for electric machine electric machine according to the invention is provided with at least one opening for the terminal box. The terminal box comprises an intermediate piece comprising an opening and detachably arranged on the outer wall of the terminal box via fixing mechanisms, so that a terminal box inner space is accessible from outside the terminal box by the opening of the intermediate piece. The intermediate piece comprises a mechanism used for fastening a cable to the intermediate piece in order to cause the cable to pass through the opening of the intermediate piece. The invention also relates to a method, wherein the cable is guided into the opening of the intermediate piece released by the terminal box in a first step, and the intermediate piece and the cable fixed on the intermediate piece are arranged on the terminal box in a second step, preferably by means of a thread fastener or rail type guiding mechanism. The invention can assemble prefab cable on the terminal box or disassemble the cable from the terminal box without any problem at any moment.

Description

Technical field [0001] The invention relates to a junction box for electrical system wiring and a method for establishing wiring. Background technique [0002] The junction box in the prior art is well known, and this junction box usually includes a cable connection terminal, and the cable is introduced from the outside of the junction box to the terminal. The function of the terminal block is the interface with the electrical system. Since the junction box is usually installed directly on an electrical machine, such as a motor, it is in a very unfavorable working environment in most cases. Therefore, the junction box usually must be protected from splashing water, and even needs to be waterproof and sealed. In addition, it is usually required to have an oil-proof, acid-proof and so-called explosion-proof structure. [0003] For example, German Patent DE 4225148 A1 describes a junction box similar to Japanese Patent Publication JP 04364338 A. There are some features in the latest...
