Abstract

A support unit for a circuit board in a sensor unit comprises a main body that defines an outer contour and includes a first joining geometry and a second joining geometry. The first joining geometry is configured to at least one of guide and electrically contact external contact elements, and includes contact receiving pockets configured to guide the external contact elements, and at least one reinforcement web that separates two adjacent contact receiving pockets. The second joining geometry is configured to join the support unit to the circuit board. The first joining geometry defines at least in part an external interface via which at least one electrical output signal of the circuit board is tapped.

First claim

The invention claimed is:

1. A support unit for a circuit board in a sensor unit for electrical connection to a separate external device having external contact elements comprising:
an elongated main body defining an outer contour and including: (i) a first joining geometry configured to guide the external contact elements into electrical contact with the circuit board; and (ii) a second joining geometry defined in the main body and configured to join the support unit to the circuit board,
wherein the first joining geometry has: (i) elongated contact receiving pockets configured to guide the external contact elements by which the separate external device is engaged to the support unit; and (ii) at least one elongated reinforcement web which separates two adjacent contact receiving pockets;
wherein the first joining geometry defines at least in part an external interface via which at least one electrical output signal of the circuit board is tapped,
wherein said receiving pockets open at a top surface of one end of said elongated main body and said second joining geometry is configured as a receiving opening open at an opposite end of said elongated main body.

2. The support unit as claimed in claim 1 , wherein:
the main body is configured as a cylinder with the second joining geometry;
the receiving opening is arranged to intersect said contact receiving pockets and adapted to an outer contour of the circuit board; and
the second joining geometry is configured to receive the circuit board at least in part.

3. The support unit as claimed in claim 2 , wherein the second joining geometry is defined as a continuous opening in the main body.

4. The support unit as claimed in claim 2 , wherein the second joining geometry is defined on a length of the main body and includes a stop for the circuit board.

5. The support unit as claimed in claim 1 , wherein the main body includes a protruding edge.

6. A support unit for a circuit board in a sensor unit for electrical connection to a separate external device having external contact elements comprising:
a main body defining an outer contour and including: (i) a first joining geometry configured to guide the external contact elements into electrical contact with the circuit board; and (ii) a second joining geometry defined in the main body and configured to join the support unit to the circuit board,
wherein the first joining geometry has: (i) elongated contact receiving pockets configured to guide the external contact elements by which the separate external device is engaged to the support unit; and (ii) at least one elongated reinforcement web which separates two adjacent contact receiving pockets;
wherein the first joining geometry defines at least in part an external interface via which at least one electrical output signal of the circuit board is tapped; and
wherein the outer contour of the main body has an electrically conductive coating, at least in part.

7. The support unit as claimed in claim 1 , wherein the main body carries at least one of: (i) at least one electrical component part; (ii) at least one electronic component part; (iii) at least one conductor track; and (iv) at least one contact face.

8. A sensor unit comprising:
a protective sleeve defining an inner contour, a first end, and a second end;
at least one measuring cell configured to measure a pressure of a hydraulic block and including at least one connection point via which at least one electrical output signal of the measuring cell is tapped;
an electronic circuit having at least one of an electronic and electrical component part;
a circuit carrier including an internal interface configured to tap the at least one electrical output signal of the measuring cell and apply the at least one electrical output signal to the electronic circuit;
a vertically disposed circuit board,
wherein the at least one measuring cell, the circuit carrier, and the circuit board are positioned in the protective sleeve; and
a support unit including an elongated main body defining an outer contour and having: (i) a first joining geometry configured to guide-external contact elements of a separate external device into electrical contact with the circuit board; and (ii) a second joining geometry defined in the main body and joining the support unit to the circuit board,
wherein the first joining geometry has: (i) elongated contact receiving pockets configured to guide the external contact elements by which the separate external device is engaged to the support unit; and (ii) at least one elongated reinforcement web which separates two adjacent contact receiving pockets;
wherein the first joining geometry defines at least in part an external interface via which the at least one electrical output signal of the circuit board is tapped;
wherein said receiving pockets open at a top surface of one end of said elongated main body and said second joining geometry is configured as a receiving opening open at an opposite end of said elongated main body,
wherein the internal interface is positioned at a first end of the protective sleeve and the external interface is positioned at the second end of the protective sleeve; and
wherein the outer contour of the support unit supports the circuit board against the inner contour of the protective sleeve.

9. The sensor unit as claimed in claim 8 , wherein the main body has a protruding edge which terminates the protective sleeve in an inserted state.

10. The sensor unit as claimed in claim 8 , wherein the outer contour of the main body has an electrically conductive coating, at least in part, configured to electrically contact the inner contour of the protective sleeve.
