摘要:
An in-line heating device (1,2,3,4) for a liquid food or beverage preparation machine in which liquid is circulated through the heating device and then guided into a brewing chamber. This heating device comprises: a thermoblock with a metal mass (1) that incorporates an inlet, an outlet and a heating chamber extending therebetween to form a passage for guiding said liquid circulating through said mass, the mass being arranged to accumulate heat and to supply heat to the liquid; and one or more electric components (60,70,75) that are rigidly secured onto or into the thermoblock and that are connected to a printed circuit board (4) and/or a flex-print (4') arranged to control the thermoblock. The electric components are rigidly connected to the printed circuit board and/or flex-print, in particular via rigid connector pins or blades or rigid plug and socket members.

An electronic circuit with low inductance connections is disclosed. The electronic circuit includes a ground plane and a flex circuit. The flex circuit having a first surface generally facing the ground plane and a second surface opposite to the first surface. The flex circuit also having a flexible bridge defined thereof. The electronic circuit further includes a first electronic device communicatively coupled to the second surface of the flex circuit, a second electronic device communicatively coupled to the second surface of the flex circuit, and at least one conductive trace defined on the second surface of the flex circuit and extending along the flexible bridge. One end of the at least one conductive trace is configured for receiving an outbound current from the first electronic device and another end of the at least one conductive trace is communicatively coupled to the second electronic device through a vertical interconnect access.

A circuit board system comprises a first circuit board (201) furnished with SMD components (202) and conductive patterns (203). There are one or more surface-mounted support elements (206) on the first circuit board. Each of them comprises an electrically conductive bottom surface (207) soldered to a respective conductive pattern (203) of the first circuit board (201). A second circuit board (208) is mechanically connected to the one or more support elements (206). At least one electronic component (209) is mounted to the second circuit board (208) and electrically coupled to at least one conductive pattern (203) of the first circuit board (201) through at least one of said support elements (206).

A circuit board system comprising mechanical protection of electrical components is presented. The circuit board system comprises a circuit board (101) furnished with electrical components (103-111) and a protection element (102) attached to areas of the circuit board which are free from the electrical components. The protection element has thickness in the direction perpendicular to the circuit board and it is shaped to leave the electrical components unscreened in the direction perpendicular to the circuit board. Thus, the protection element constitutes barriers protecting the electrical components but still allows the electrical components to be accessed from the direction perpendicular to the circuit board for example in a flying probe testing. The body of the protection element can be made of same material as the electrically insulating body of the circuit board. Thus, the thermal expansion coefficient of the protection element can be substantially the same as that of the circuit board.

摘要:
To reduce the number of a base for terminals which protrude from and are soldered on a printed board and to lower a cost in production of the base. A printed board including an electrical junction unit provided with a set of terminals soldered on printed boards 5 and 7. The set of terminals comprise first type terminals 20 each having a small sectional area and second type terminals 21 each having a sectional area greater than that of each of the first type terminals 20. The electrical junction unit is any one of only the first type terminals 20, only the second type terminals 21a, and a combination of the first and second type terminals 20 and 21. The first type terminals 20 are inserted into and protrude from through-holes in a base 30 and are soldered on the printed boards. The second type terminals 21 are soldered on the printed boards without using the base.

The invention relates to an electric switch (1) with a housing (2). A contact system (3) is located in the housing (2). An actuation element (6) projects beyond a first side (4) of the housing (2) for activating the switching operation in the contact system (3). Electrical connections (7) project on a second side of the housing (2) for the contact system (3). The electrical connections (7) can be fastened to a printed circuit board (8). At least one support element (10) is located on the second side (5) of the housing (2) so that the switch (1) is fixed substantially to the printed circuit board (8) in the region of the electrical connections (7) after being mounted onto the printed circuit board (8).
