Abstract

An electronic device includes a shell, a contact member, a temperature sensor, and a circuit board. The shell has an accommodating space. The contact member is arranged on the shell, and at least part of a surface of the contact member forms an outer surface of the electronic device. The temperature sensor is arranged in the accommodating space and has a positive electrode and a negative electrode. The circuit board is arranged in the accommodating space and provided with a positive wire and a negative wire. The positive wire is connected to the positive electrode of the temperature sensor. The negative wire is connected to the negative electrode of the temperature sensor. At least one of the positive wire and the negative wire is thermally conductively connected to the contact member.

Core Innovation

An electronic device comprises a shell having an accommodating space, a contact member arranged on the shell in which at least part of a surface of the contact member forms an outer surface of the electronic device, and a temperature sensor arranged in the accommodating space and having a positive electrode and a negative electrode. The temperature sensor performs temperature measurement according to a temperature transferred from the positive electrode and the negative electrode via conductors connected to the sensor.

A circuit board is arranged in the accommodating space and provided with a positive wire and a negative wire, where the positive wire is connected to the positive electrode of the temperature sensor and the negative wire is connected to the negative electrode of the temperature sensor. At least one of the positive wire and the negative wire is thermally conductively connected to the contact member so that the contact member provides a heat-transfer path to the temperature sensor through the at least one thermally conductively connected wire.

The contact member and the temperature sensor are arranged on two opposite sides of the circuit board, and the circuit board comprises a multi-layer wire structure formed by a metal layer and insulating dielectric layers alternately arranged in sequence. The positive wire comprises a positive wire body and a first metallized via extending through surfaces on the two opposite sides of the circuit board, with the positive wire body electrically connected to the first metallized via, and the negative wire comprises a negative wire body and a second metallized via likewise extending through the two opposite sides with the negative wire body electrically connected to the second metallized via.

Claims Coverage

The independent claim is a single electronic device claim defining a shell-mounted contact member forming part of the outer surface and a temperature sensor connected to positive and negative electrodes via a multilayer circuit board with thermally conductive wiring to the contact member. It further specifies two-opposite-side placement across the circuit board and a multi-layer wire structure with metal and insulating dielectric layers, including metallized vias extending through opposite sides.

Thermally conductive contact-member heat-transfer path to a temperature sensor via positive and negative wires

An electronic device having a shell with an accommodating space, a contact member whose surface forms an outer surface, a temperature sensor with a positive electrode and a negative electrode, and a circuit board with a positive wire and a negative wire connected to the respective electrodes, wherein at least one of the positive wire and the negative wire is thermally conductively connected to the contact member and the temperature sensor measures temperature according to temperature transferred from the at least one thermally thermally conductively connected wire.

Two-opposite-side arrangement using multilayer circuit board and metallized vias

The contact member and the temperature sensor are arranged on two opposite sides of the circuit board, wherein the circuit board comprises a multi-layer wire structure formed by a metal layer and insulating dielectric layers alternately arranged in sequence; the positive wire includes a positive wire body and a first metallized via extending through surfaces on the two opposite sides with electrical connection between the positive wire body and the first metallized via; and the negative wire includes a negative wire body and a second metallized via extending through surfaces on the two opposite sides with electrical connection between the negative wire body and the second metallized via.

The claim coverage centers on a wearable electronic device in which a contact member forming part of the outer surface is thermally coupled to a temperature sensor through positive and/or negative wires on a multilayer circuit board, with the contact member and sensor placed on opposite sides and electrical/structural conduction through metallized vias.
