Pressure sensor device having breakable mounting member
First Claim
1. A pressure sensor device comprising:
- a sensor portion having a pressure-responsive element for measuring pressure;
an inlet port for introducing pressure to be measured into the sensor portion, the inlet port being connected to the sensor portion; and
a mounting member for mounting the sensor device on a vehicle, the mounting member including a connecting member for connecting the sensor portion to the mounting member and being disposed apart from the inlet port, the connecting member having a structure constructed and arranged to break before the inlet port breaks to separate the sensor portion from the mounting member when a predetermined level of impact is imposed on the sensor portion, thereby protecting the inlet port from being damaged by the impact.

Abstract
A pressure sensor portion having a pressure-responsive element for detecting gas pressure in reference to the atmospheric pressure is connected to a mounting body such as a canister mounted on a vehicle by means of a fragile connecting member. The connecting member breaks off to dismount the sensor device from the mounting body when a high impact due to an accidental collision or crash is imposed on the sensor device, and thereby an inlet port connected to the sensor portion for introducing gas pressure thereinto is prevented from being broken or damaged by such a collision impact. The fragile connecting member may include a tubular pipe formed integrally with a cover that hermetically closes an inner cavity of the sensor portion. A mounting bracket connected to the sensor portion via the fragile connecting member may be used to mount the sensor device on the mounting body.

9. A pressure sensor device, comprising;
-
a sensor portion having a pressure-responsive element for measuring pressure comprising a housing having a cavity in which the pressure-responsive element is disposed and a cover hermetically closing the cavity; an inlet port for introducing pressure to be measured into the sensor portion, the inlet port being connected to the sensor portion, wherein the inlet port is connected to one end surface of the housing, and the cover is fixed to the other end surface of the housing; and a mounting member for mounting the sensor device on a vehicle including a connecting member having a structure constructed and arranged to break before the inlet port breaks to separate the sensor portion from the mounting member when a predetermined level of impact is imposed on the sensor portion, thereby protecting the inlet port from being damaged by the impact, and further including a bracket for mounting the sensor device on the mounting body, the connecting member being integrally formed with the cover, wherein the connecting member comprises an upper plate and bridging portions that connect the upper plate to the cover at both sides of the upper plate, so that the upper plate is disposed with a space between the upper plate and the cover, wherein the bracket is inserted in the space of the connecting member and fixed thereto, and wherein the bridging portions break off when the predetermined level of impact is imposed on the sensor portion. - View Dependent Claims (10, 14)
