Abstract
An electronic device includes a housing, a circuit substrate, a connector, and a seal obtained by a sealant having fluidity being hardened. The housing includes a lower case and an upper case that covers the lower case. The connector is disposed between the upper case and the lower case. The lower case has a case groove. A connector projection disposed on the connector and a case projection disposed on the upper case are fitted into the case groove. The connector includes a connector groove, and the case projection is fitted into the connector groove. An obstructor for inhibiting flow of the sealant is disposed in the case groove or the connector groove.

An electronic device comprising:
- a box-shaped housing;
- a circuit substrate housed in the housing;
- a connector that is mounted to the circuit substrate and that has a portion exposed to outside of the housing;
- and
- a seal obtained by a sealant having fluidity being hardened,
- wherein the housing includes a lower case and an upper case that covers the lower case,
- wherein the connector is disposed between the upper case and the lower case,
- wherein the lower case has, in a surface on the upper case side of the lower case, a case groove that extends along a peripheral edge portion of the surface,
- wherein the upper case has, on a surface on the lower case side of the upper case, a case projection that extends along a peripheral edge portion of the surface,
- wherein the connector has a connector groove in a surface on the upper case side, and has a connector projection on a surface on the lower case side,
- wherein the connector projection is fitted into the case groove and the case projection is fitted into the connector groove at a position at which the connector is disposed between the upper case and the lower case,
- wherein the case projection is fitted into the case groove at a position at which the connector is not disposed between the upper case and the lower case,
- wherein the seal is filled in a gap between the case groove and each of the case projection and the connector projection, and in a gap between the connector groove and the case projection,
- wherein an obstructor for inhibiting flow of the sealant is disposed in the case groove or the connector groove,
- wherein each of the case groove and connector groove has an inner wall and an outer wall, a width between the inner wall and the outer wall, a depth and a length, and
- wherein the obstructor is a projection disposed on a side wall of the case groove or the connector groove, the obstructor having a height, a depth extending into the case groove or the connector groove, and a width that is less than a length of the case groove or the connector groove.
