The control box includes openings that are sized and shaped to allow attachment of different sized pipes and conduits to the control box.

Provided is an electronic control device that can reduce a usage amount of an adhesive constituting a seal member, by relieving a stress caused in the seal member disposed in a gap between a first housing part and a second housing part in a high-temperature environment. In an electronic control device including: a component mounting board mounted with an electronic component; and a first housing part and a second housing part that are fixed to each other via a seal member and define a first space that accommodates the component mounting board, at least one predetermined housing part of the first or second housing part has a recess formed on a surface facing the seal member, and a second space is formed between the recess and the seal member.

A plate-shaped conductor is placed on an upper surface of a plate-shaped heat dissipation member with an insulation member interposed therebetween. A heat insulation member is placed at a location that is different from a location where the conductor is placed, on the upper surface of the heat dissipation member. An FET is electrically connected to the conductor. When current flows through the FET, the FET generates heat. A microcomputer that outputs a control signal for controlling operation of the FET is connected to an upper surface of the circuit board and is located opposite to the heat insulation member with the circuit board interposed therebetween.

The sensor includes a PCB, a sensing portion and at least one adjusting portion. The PCB is electrically connected to the sensing portion and the adjusting portion, respectively, and the at least one adjusting portion is configured to adjust output signals of the PCB. The at least one adjusting member is inserted into the adjusting portion for adjusting the output signals of the PCB. The structure of the present disclosure can control external lamps to light or extinguish so as to realize the functions of dimming light brightness, setting light duration, adjusting energy-saving parameters and proportion. So, such structure can be easily operated with a wide range of applications.

An example apparatus includes a connection module. The example connection module includes a connection interface and a connection matrix having a root transmission line to conduct signals to and from the connection interface. The connection matrix also includes branch transmission lines that are connectable electrically to the root transmission line to conduct the signals to and from the root transmission line. Each of the branch transmission lines is part of an electrical pathway between a device and the root transmission line. A housing encloses the connection matrix and enables access to the connection interface. The root transmission line and the branch transmission lines are each multi-conductor transmission lines that conduct the signals in transverse electromagnetic (TEM) mode.
