Background
Pump assemblies, such as heating circulation pump assemblies, generally form a structural unit that includes an electric drive motor and a pump. The electric drive motor is arranged in a motor housing or stator housing, which is connected to the pump housing. The electrical and electronic components required for controlling and regulating the electric drive motor are usually provided in a junction box or electronics housing, which is connected to the motor housing or stator housing,
In order to connect the coils in the motor housing or stator housing with the power connection wires and to connect other electronics as required, plug contacts or cable channels need to be provided on the junction box or electronics housing. For this purpose, it is known to cast the electrical conductor circuits in the composite material of the finished junction box or electronics housing, but this makes the casting process of the junction box or electronics housing rather complicated. A further alternative is that cable channels can be provided in the motor housing or stator housing and the junction box or electronics housing, through which cables are led and then connected internally to a circuit board provided with electronics, which in turn leads to higher costs and is prone to errors in installation. A further problem is the need to seal the cable in the cable channel, which also increases the cost.
For this purpose, chinese patent application publication No. CN104904099a discloses a pump assembly having an electric drive motor arranged in a stator housing and an electronics housing connected to the stator housing, in which at least one circuit board with electronics is arranged, wherein at least one separate connecting element, which is formed as a molded part of synthetic material, is arranged on or in the electronics housing, which has a first electrical plug-in connection with a corresponding electrical plug-in coupling on the circuit board, and a second electrical plug-in connection with the first electrical plug-in connection via a conductor circuit and is used for electrical connection with a component located outside the electronics housing. This patent provides the connection elements on or in the electronics housing, but when it is used for electrical connection with the coils in the motor housing or stator housing, the electrical socket still needs to be cast on the motor housing or stator housing, the casting process is complicated and the cost is high.
