Embodiment Construction

[0043] The pump unit according to the invention shown in the example has a pump housing 2 which, in this example, is connected to a stator housing 6 via a clamping ring 4. However, other suitable connectors can also be provided. An electric drive motor is provided in the stator housing 6 and the electric drive motor includes a stator and a rotatable rotor 8 arranged in the stator. A slot tube 10 is provided between the rotor 8 and the stator. In other words, this is a wet running electric drive motor. The pump unit shown here is a heat pump unit. An electronic device housing or junction box 12 is placed on the axial end of the stator housing 6 facing away from the pump housing 2. In this example, the junction box 12 is composed of three parts, namely a first housing part in the form of a cover 14, a second housing part in the form of an intermediate part 16, and a third housing in the form of a lower part 18. Body parts. The cover 14, the middle part 16 and the lower part ...

Abstract

The invention relates to a pump unit having a terminal box (12) with at least a first housing part (14) and a second housing part (16), both of which can be connected via a hinge connection (20). are pivotably connected to each other, wherein the hinge connection (20) has an extension (a) in the direction of its pivot axis (S) which is correspondingly smaller than that of the terminal box (12) parallel to the pivot axis (S). Half of the maximum stretch (b) in direction S).

Description

Technical field [0001] The invention relates to a pump unit with a junction box, which has at least a first housing part and a second housing part, which are pivotally connected to each other by a hinge connection. Background technique [0002] Patent document EP1524752A1 discloses a junction box for a pump unit, which has a swingable cover. The swingable cover is connected with the lower part of the junction box through a hinge connector including two hinge segments arranged on the outer corners. In addition to the swingability, the cover can also be completely removed from the hinge receiving portion in the lower part of the junction box, which can be achieved by elastic deformation of the hinge receiving portion. Here, the removal is realized in such a way that the cover further swings outward through its normal opening position, whereby the hinge bolts mounted on the cover are removed from the hinge receiving part. This is of course impossible when there is not enough space...
