Problems solved by technology

[0004] However, casting of a cover with a through hole as disclosed in JP2013-165107A requires a movable mold that moves in a direction perpendicular to the mold opening direction in addition to a movable mold that moves in the mold opening direction, resulting in the overall mold complex structure of
Although it is possible to perform drilling after casting without forming through-holes during casting, this inevitably requires a step of removing burrs that occur during drilling, resulting in an increased number of steps

Embodiment Construction

[0017] An electronic control unit according to an embodiment will now be described with reference to the drawings. The electronic control unit of the embodiment is applied to, for example, an electric power steering system of a vehicle, and can control a control operation of a motor that generates assist torque that assists a driver's steering.

[0018] now refer to Figures 1 to 6 The configuration of the electronic control unit 1 is described. The electronic control unit 1 includes a substrate 10, a first cover 30, a second cover 40, and the like. figure 1 and 2 Both omit the first cover 30 . Figure 6 The substrate 10 is omitted.

[0019] The substrate 10 is a printed circuit board formed into a substantially rectangular shape by an insulating material. Hereinafter, one surface of the substrate 10 is referred to as a first surface 11 , and the other surface is referred to as a second surface 12 . Various electronic components are mounted on the substrate 10 . For exa...

Abstract

The invention relates to an electronic control unit (1, 2), which includes a substrate (10), a first cover (30) and a second cover (40). The electronic components (21, 25) are mounted on the substrate (10). The first cover (30) arranged in a substrate (10) and a surface (11) relative and includes a first side wall portion (32), the substrate (10) perpendicular to the direction of extension; and the clamp part (34, 35), from the first side wall portion (32) transverse projection. The second cover (40) is arranged to be opposite to the other surface (12) of the substrate (10) and comprises second side walls (45) and a groove (47, 49). Second side walls (45) facing the first side wall portion (32). The slot (47, 49) in the second side wall portion (45) formed from the perpendicular to the substrate (10) in the direction of observation, each slot (47, 49) is the shape of the corresponding clamp part (34, 35) concave shaped convex shape consistent. Each groove portion (47, 49) is fitted to the corresponding clamping part of at least one clamping part (34, 35).

Description

technical field [0001] The present disclosure relates to an electronic control unit having a cover arranged on either side of a substrate. Background technique [0002] There is known an electronic control unit having covers respectively arranged on both faces of a substrate so as to constitute a case accommodating the substrate for protecting the substrate from dust, water, and the like. For example, JP2013-165107A discloses an electronic control unit in which covers are arranged on both faces of a base plate and fixed to each other by snap fitting. [0003] In the electronic control unit of JP2013-165107A, the first cover is arranged on one surface of the substrate and has a clamp portion on its side wall, and the second cover is arranged on the other surface of the substrate and has a through hole on its side wall. hole. Each jaw of the first cover fits in each through hole of the second cover, so that the two covers are fixed to each other. [0004] However, casting o...
