Abstract

An electronic unit of a fluid sensor or fluid valve has a substantially cylindrical housing with a longitudinal axis and an open end face, which can be closed by a lid, several spacers formed as separate parts, which can be introduced into the housing in direction of the longitudinal axis and are directly stacked on top of each other. At least one spacer at least one electronic component is attached, which together with the spacer forms a premounted unit to be introduced into the housing.

First claim

The invention claimed is:

1. An electronic unit of one of a fluid sensor and fluid valve, the electronic unit comprising a substantially cylindrical housing with a longitudinal axis and a closable open end face, a plurality of spacers formed as separate parts, configured to be accepted into the housing in direction of the longitudinal axis and which are directly stacked on top of each other, wherein to at least one spacer at least one electronic component is attached, the at least one electronic component together with the spacer forming a premounted unit configured to be introduced into the housing, wherein at least one spacer forms a circumferential ring in which the region circumscribed carries the electronic component, and wherein the electronic component includes a circuit board forming a bottom of the premounted unit which contacts the ring.

2. The electronic unit according to claim 1 , wherein, as seen in direction of the longitudinal axis, the spacers have the same contour.

3. The electronic unit according to claim 1 , wherein the spacers have latching hooks which engage counter-contours at the adjacent spacers, forming a positive connection acting in the longitudinal axis.

4. The electronic unit according to claim 3 , wherein the latching hooks and counter-contours are formed at an axial edge of its associated ring.

5. The electronic unit according to claim 1 , wherein the spacers each are formed as circumferential rings.

6. The electronic unit according to claim 5 , wherein the spacers sit on each other at their axial edges.

7. The electronic unit according to claim 1 , wherein the circuit board fills the radial interior of the ring.

8. The electronic unit according to claim 1 , further comprising on at least one spacer a lateral electrical plug connection configured to receive an electrical plug with a cable.

9. The electronic unit according to claim 8 , wherein the spacers have an inwardly retracted portions in whose region the electrical plug connection is seated.

10. The electronic unit according to claim 1 , wherein the housing has a lateral opening beside the open end face and the opening geometries of the open end face and the lateral opening are the same, such that the same lid can be put onto the end face or the opening.

11. The electronic unit according to claim 1 , wherein the lid is electrically coupled with one of the electronic components.

12. The electronic unit according to claim 1 , wherein at least one of the sensor, the valve and the lid is coupled via a cable with an electronic component on the spacer which spacer is located nearest to the corresponding one of the sensor, the valve and the lid, respectively.

13. The electronic unit according to claim 1 , wherein the spacers form a premounted stack which is insertable into the housing.

14. An electronic unit of one of a fluid sensor and fluid valve, the electronic unit comprising a substantially cylindrical housing with a longitudinal axis and an open end face, closable with a lid, a plurality of spacers formed as separate parts introduced into the housing in a direction of the longitudinal axis and directly stacked on top of each other, wherein at least one electronic component is attached to at least one axially-open spacer, the at least one electronic component together with the spacer forming a premounted unit configured to be introduced into the housing, wherein on at least one spacer electrical contacts are mounted touching counter-contacts of adjoining spacers electrically coupling the electronic components with each other at different spacers, wherein the electronic unit further comprises guide elements at the spacers for at least one of aligning and securing the position of contact-forming, protruding pins, wherein at least one guide element is formed by a wall with openings through which the pins extend, and the wall protrudes radially inward from the spacer.

15. An electronic unit of one of a fluid sensor and fluid valve, the electronic unit comprising a substantially cylindrical housing with a longitudinal axis and an open end face, closable with a lid, a plurality of spacers forming separate parts that are configured to be accepted into the housing in a direction of the longitudinal axis and directly stacked on top of one another, wherein to at least one spacer at least one electronic component is attached, the at least one electronic component together with the spacer forming a premounted unit configured to be introduced into the housing, wherein in the housing at least some spacers without electronic components are provided, configured to create a spaceholder.

16. A fluid sensor or fluid valve unit with one of a fluid sensor and a fluid valve and an electronic unit put onto the fluid sensor and onto the fluid valve, respectively, wherein electronic unit comprises a substantially cylindrical housing with a longitudinal axis and an open end face configured to be closable with a lid, several spacers formed as separate parts, configured to be introduced into the housing in direction of the longitudinal axis and which are directly stacked on top of each other, wherein to at least one spacer at least one electronic component is attached, the at least one electronic component together with the spacer forms a premounted unit to be introduced into the housing, wherein the electronic unit forms a fluid sensor controller and a fluid valve controller, respectively.
