[0042] Such as 1A to Figure 3BAs shown in the illustrated embodiment, the housing 10 includes a front cover 102 and a rear cover 104 connected to the front cover 102. The lead frame 50 is disposed in the cavity 116 formed by the front cover 102 and the rear cover 104, and the rear port 114 is disposed on the side of the rear cover 104 opposite to the cavity 116.
