Abstract

The assembly has a stator connecting element (48) and a network connecting element (62) formed as molded plastic parts, and arranged on or in an electronics housing. The connecting elements include electrical plug-in connectors (52, 66) that are connected to a corresponding electrical plug-in coupling on a printed circuit board. The connecting elements include other electrical plug-in connectors (54, 68), which are connected to the former electrical plug-in connectors via cast conductor tracks (56) and serves as an electrical connection of a component that is located outside of the housing.

Description

Technical field

[0001] The invention relates to a pump unit having the characteristics described in the preamble of claim 1. Background technique

[0002] A pump unit, such as a heating circulating pump unit, usually constitutes a structural unit, which includes an electric drive motor and a pump, such as a centrifugal pump. The electric drive motor is arranged in a motor housing or a stator housing, and the motor housing or the stator housing is connected with the actual pump, that is, the pump housing. The electrical and electronic devices required to control or regulate the electric drive motor are usually arranged in a junction box or an electronic device housing, and the electronic device housing is connected to the stator housing.

[0003] In order to connect the coil in the stator housing to the power connection wire, and to connect other electronic devices as required, it is necessary to provide plug contacts or cable channels on the electronic device housing. For this re...
