Problems solved by technology

In particular, the housing 72 used as a part of the electronic unit 70 restricts the direction of assembly, thereby placing restrictions on the design of the electronic unit 70
In the electronic unit 60 and the electronic unit of the above-mentioned publication, the connector is directly mounted to the housing, and the vibration transmitted to the housing is directly transmitted to the connector, thereby possibly causing damage to the connector.
Also, since the housing and connector have different coefficients of thermal expansion, the connector may be damaged by the heat transferred to the housing

Abstract

An electronic unit includes a circuit board, a connector and a housing. The connector is electrically connected to the circuit board through a lead wire. The housing accommodates therein the circuit board having an opening through which a part of the connector is exposed outside the housing, and a clearance is formed between an edge portion of the opening of the housing and the connector. The electronic unit further includes an outer rib, an inner rib and a projection. The inner rib is formed on the inner side of the housing than the outer rib. The projection is inserted between the outer rib and the inner rib.

Description

technical field [0001] The present invention relates to electronic units, and more particularly to an electronic unit provided with a housing in which a circuit board is accommodated and a connector having leads electrically connecting the connector to the circuit board . Background technique [0002] An electronic unit provided with a connector mounted on a printed circuit board arranged in a housing has a structure that prevents wires from entering the housing to prevent electric shock. in such as Figure 8 In a conventional electronic unit 50 shown in , a connector 53 is connected to one end of a wire harness 52 , and the other end of the wire harness 52 is connected to a circuit board (not shown) disposed in a housing 51 of the electronic unit 50 . The wire harness 52 has therein a plurality of electric wires each connected to a circuit board, and the housing 51 has therein a grommet 54 through which a plurality of holes are formed and through which the electric wires a...
