An electric connection box of the present invention comprises an upper case, a lower case fitting with the upper case, a connector housing connecting with a connector from the outside, one or a plurality of bus-bars each arranged sandwiched between the upper case and the lower case and having a terminal portion comprised of a plurality of terminal pieces positioned arranged in parallel inside the connector housing and a bus-bar body integrally formed with the terminal portion, and an insulator provided at least between the plurality of terminal pieces to connect and secure the terminal pieces to each other, by which insulator the narrow width terminal pieces are connected with each other and disturbance of the pitch or deformation is prevented.

Electric connection box

An electrical connection box has electronic components mounted therein and includes a heat pipe for radiating heat generated from the electronic components to the outside. The heat pipe has a heat absorbing portion inside the connection box and a heat radiating portion outside the connection box. The heat pipe is formed of an electrically conductive material, and an electrically conductive heat collecting member is provided for collecting the heat generated from the electronic components. The heat absorbing portion of the heat pipe is connected to the heat collecting member, and a grounding current is supplied to the heat pipe and the heat collecting member.

Electrical connection box

A female-type terminal unit provided with an insertion portion for insertion of a male-type terminal at one end and a conductor connection portion for connecting with a conductor at the other end. A male-type terminal insertion portion is formed by facing plate-shaped terminal pieces. At the base side of the plate-shaped terminal pieces is provided a stopper piece for stopping the spread of the two plate-shaped terminal pieces when a male-type terminal is press-fit there. The two facing plate-shaped terminal pieces will not plastically deform due to twisting by the male-type terminal. Further, the stopper piece prevents the plate-shaped terminal pieces from excessively spreading apart.
