Embodiment Construction

[0023] The plug connector arrangements 10 and 110 shown in the figures are used in submersible pumps as power and / or control cables 11, and for design and assembly purposes they are configured so that when submerged, i.e. underwater, Even if the cable 11 connected to the cable side plug connector part 12 , 112 of the pump side plug connector part 13 , 113 is damaged, moisture from the outside cannot penetrate into the submersible pump 15 , 115 .

[0024] 1 to 4 show a three-pole plug connector device 10 according to a first exemplary embodiment of the present invention.

[0025] FIG. 1 shows a cable-side plug connector part 12 comprising an insulating housing 16 for three plug connectors 17, which are arranged in the configuration shown in FIG. Configured as pin connectors rolled into a single piece. For this purpose, the insulating housing 16 for each plug connector 17 has a stepped axial through bore 18, in the front region of the bore 18, in the central region of the bore ...

Abstract

A device (10) for supplying electrical power and signals to a submersible pump (15) in such a way that it is sealed from liquids via an external electrical cable (11) extending through a opening (49) within the head (48) of a pump housing (50). The device comprises a plug connector device (10), whose pump-side plug connector part (13) is arranged within the through opening (49) of the housing head (48) so as to be axially movable and whose cable-side plug connector part (12) is provided with an insulation coating (25), which extends from an area of the cable jacket (20) down to its plug connector contacts (17), and about which, behind its free end, a coupling part (27) is provided which can be connected in a mechanically fixed manner to a counterpart coupling part (54) on the exterior endof the through opening (49) within the head (48) of the pump housing (50).

Description

technical field [0001] According to the preamble of claim 1 , the invention relates to a device for supplying electrical power and / or control signals to a submersible pump in a liquid-tight manner by sealing. Background technique [0002] In submersible pumps, all cables such as voltage supply cables, cables to the float switch, etc. are usually routed directly to the inside of the pump housing through feedthroughs filled with sealant, and the cables are connected to the relevant electrical components . According to current thinking, this represents the most cost-effective and simplest provision of power and / or control signals sealed from liquid. [0003] However, submersible pumps of this type are generally handled roughly, whether in the private sector, industry, etc. underground, by fire brigades or other aid organizations. Consequently, upstream or in the area where the cable exits towards the housing head of the pump housing, it repeatedly occurs that the cable or wir...
