Physical quantity measuring device

摘要

A plate-shaped circuit board configured to receive a detection signal from a detector is housed in a case and is held by a holder with a flat substrate surface thereof intersecting with a bottom surface of a cover member. The holder is attached to the cover member. The cover member includes a cover body, and elongated supporting portions projecting from the bottom surface of the cover body into the case. The supporting portions each include a pair of support projections that support one of opposite side surfaces of the circuit board along a projecting direction of the supporting portions. The holder includes a flat portion provided with engagement pieces engageable with a second substrate.

主权项

1. A physical quantity measuring device comprising:
a cylindrical case having a first open end and a second open end; a cover member attached to the first open end of the case, the cover member having a bottom surface; a detector provided to the second open end of the case to detect a physical quantity; a joint provided with the detector and attached near the second open end of the case; a plate-shaped circuit board configured to receive a detection signal from the detector; and a holder attached to the cover member to hold the circuit board in a manner that a flat surface of the circuit board intersects with the bottom surface, the holder comprising an engagement piece engageable with the circuit board, the cover member comprising: a cover body defining the bottom surface; and a supporting portion projecting from the bottom surface toward the joint, the supporting portion comprising a pair of support projections configured to support opposite side surfaces of the circuit board along a projecting direction of the supporting portion.
