Definitions

  • the present invention relates to an electronic device, in particular, to a positive temperature coefficient (PTC) thermistor device.
  • PTC positive temperature coefficient
  • Thermistor device has been widely used in current limiting circuit, including motor staring circuit in a refrigeration device such as a refrigerator. After being used for long time, the physical structure of the prior art PTC device may deteriorate, creating abnormal heat inside the device and breaking the PTC element into fragments. Since the fragments may still be connected with the terminal, issues such as arc discharging, overheating, over current, etc. may occur.
  • Current conducting contact elements are arranged offset relative to each other on the component.
  • At least one positioning element is arranged on the component.
  • At least one of the contact elements or the positioning element comprise a tensioned member which is electrically separated from the contact elements.
  • At least one contact element and position element pair is arranged on the component such that the principle of the short, i.e. high pressing force, asymmetrical stress on component, and the long, i.e. strong tilting of bridging members after destruction of the component, lever arm is guaranteed.
  • German patent application no. DE 19638631 A1 discloses a contact assembly for semiconductor resistors, consisting of a set of contact elements asymmetrically arranged so that they lean, staggered in relation to each other, against the opposite side surfaces of an electrical structural member.
  • European patent application no. EP-A-1511053 discloses a motor start relay comprising a positive temperature PTC thermistor, a PTC case of heat resistant resin for receiving the PTC thermistor horizontally, first and second contact/terminals each having contacts electrically engaged with a respective electrode surface of the PTC thermistor in the PTC case, a housing receiving the PTC case and a cover attached on the housing.
  • thermistor portion PTC1 is rotated by spring contact (510) with a force F1
  • thermistor portion PTC2 is pushed by spring contact (570) at the reverse direction and is dropped through an opening of the PTC case.

  • the elastic force of the third elastic support pushes the fragments of the electronic element away so that the fragments do not contact with one of the first support and the second support, disconnecting the electronic element with one of the terminals, disconnecting the circuit and eliminating the issues of arc discharging and overheating.

  11. Elektronische Einrichtung (100) nach Anspruch 10, wobei eine durch das zweite elastische Teil (62) auf das elektronische Bauelement (5) ausgeübte Federkraft größer ist als die Summe der durch die zwei Gabeln (61a, 61b) auf das elektronische Bauelement (5) ausgeübte Federkraft.
  12. Elektronische Einrichtung (100) nach Anspruch 1, wobei es sich bei dem elektronischen Bauelement (5) um eine Scheibe mit positivem Temperaturkoeffizienten (PTC) handelt.
  13. Elektronische Einrichtung (100) nach Anspruch 1, wobei die erste Stütze (7) mit dem ersten Anschluss (3) integral ausgebildet ist.
  14. Elektronische Einrichtung (100) nach Anspruch 1, wobei die zweite Stütze (8) mit dem zweiten Anschluss (4) integral ausgebildet ist.
  15. Verfahren zum Fertigen einer elektronischen Einrichtung (100), wobei das Verfahren Folgendes umfasst:
    Auswählen einer elektronischen Einrichtung, die ein elektronisches Bauelement (5) mit einer ersten Elektrode (51) und einer zweiten Elektrode (52), die auf dessen entgegengesetzten Seiten angeordnet sind, einen ersten Anschluss (3) und einen zweiten Anschluss (4), eine erste Stütze (7), die am ersten Anschluss (3) angebracht und elektrisch mit diesem verbunden ist, wobei die erste Stütze (7) ein erstes Kontaktteil (71) umfasst, das die erste Elektrode (51) kontaktiert und elektrisch mit dieser verbunden ist, eine zweite Stütze (8), die am zweiten Anschluss (52) angebracht und elektrisch mit diesem verbunden ist, wobei die zweite Stütze (8) ein zweites Kontaktteil (81) umfasst, das die zweite Elektrode (52) kontaktiert und elektrisch mit dieser verbunden ist, und eine dritte elastische Stütze (6) umfasst, die ein drittes Kontaktteil (63) umfasst, das die erste Elektrode (51) oder die zweite Elektrode (52) kontaktiert, und
    Anordnen der elektronischen Einrichtung innerhalb einer Abdeckung (1) und eines Sockels (2),
    dadurch gekennzeichnet, dass die dritte elastische Stütze (6) dafür vorgesehen ist, ein erstes und ein getrenntes zweites Bruchstück des elektronischen Bauelements (5) außer Kontakt mit entweder der ersten Stütze (7) oder der zweiten Stütze (8) zu schieben, wenn das elektronische Bauelement (5) in einem Ausfallzustand bricht.
