Abstract

A flexible circuit (200) configured to electrically couple circuit boards (104, 106) is provided. The flexible circuit includes opposite circuit board mating ends (202, 204) and a flexible body (206) extending therebetween. Conductive pathways (212) extend along the body of the flexible circuit to electrically couple the circuit boards. The flexible circuit also includes a temperature sensing circuit (216) including leads (230) having a distal end coupled to a temperature sensor (218) and a temperature contact (232) located proximate to one of circuit board mating ends. The temperature sensor is located at an intermediate position along the body between the circuit board mating ends. The temperature contact is configured to deliver temperature signals from the temperature sensor representative of a local flexible circuit temperature.

Description

technical field [0001] The present invention relates to a flexible circuit with a temperature sensor. Background technique [0002] Connector assemblies are used in many applications, such as servers, routers, and data storage systems for transmitting signals and / or power through electrical systems. Connector assemblies typically include a backplane or midplane circuit board, a motherboard, and multiple daughter cards. The connector assembly also includes one or more electrical connectors attached to the circuit board for interconnecting the daughter card and the circuit board when the daughter card is inserted into the electrical system. The flex circuit can be electrically coupled to the daughter card and the circuit board to transfer power and data signals therebetween. The electrical system includes components coupled to the circuit board. Flexible circuits carry signals and / or power between components of an electrical system. Electrical systems have been proposed th...
