PROBLEM TO BE SOLVED: To share a connector housing for an enclosure using a cover or a base to which molding processing or plating processing is applied.SOLUTION: While exposing a part of a connector housing 330A which is mounted on a circuit board 300A, the circuit board 300A is encapsulated and accommodated in the enclosure that is formed from a base 200A and a cover 400A. A seal gap between the cover 400A and the connector housing 330A is formed from a composition plane of a first recessed line 453 and a first projected line 353, and a waterproof sealant 501 is applied. A seal gap between the base 200A and the connector housing 330A is formed from a composition plane of a second projected line 202 and a second recessed line 302 and a waterproof sealant 502 is applied. The seal gaps extend insides and outsides with an inner boundary surface 335 of a partition wall 333 of the connector housing 330A as a border, and the composition plane is made smooth by enlarging a seal width. Planar movement of the seal gap is regulated by a side face projected line 352A and a side face recessed line (452A).SELECTED DRAWING: Figure 4A
【課題】成形加工或いは板金加工されるカバー又はベースを用いた筐体に対して、コネクタハウジングを共用可能にする。【解決手段】回路基板300Aに搭載されたコネクタハウジング330Aの一部を露出させて、回路基板300Aをベース200Aとカバー400Aで構成された筐体に密閉収納するものにおいて、カバー400Aとコネクタハウジング330Aとのシール間隙は、第一凹条453と第一凸条353との嵌合面によって構成して防水シール材501を塗布し、ベース200Aとコネクタハウジング330Aとのシール間隙は、第二凸条202と第二凹条302との嵌合面によって構成して防水シール材502を塗布し、各シール間隙はコネクタハウジング330Aの仕切壁333の内側境界面335を境として内外に延在して、シール幅を広げて嵌合斜面をなだらかにする。シール間隙の平面移動は側面凸条352Aと側面凹条(452A)によって規制されている。【選択図】図4A
