Title:
PRESSURE-ACTIVATED SWITCH AND JOINT UNIT
Document Type and Number:
WIPO Patent Application WO/2013/035365
Kind Code:
A1
Abstract:
The present invention allows a joint, bellows, and an actuation section to be easily combined with the main body of a pressure-activated switch, and the pressure-activated switch to be made small by eliminating the use of a cap or the like at the part where the joint is attached. The bellows (12) is connected with the joint (11) in order to construct a joint unit (1). A slit section (112a) is formed on the base of a hexagonal section (112) of the joint (11), said base part being positioned on a junction section's (111) side. A hexagonal insertion hole (21a) is created on the bottom plate (21) of a reinforcement plate (2), and the hexagonal section (112) is fitted into the insertion hole (21a). An actuation section (4) is combined with the reinforcement plate (2) in order to construct an assembly (10). Fixation claws (22a, 23a) are formed on the reinforcement plate (2). An insertion hole (31a) and a notch section (31b) are formed on the bottom plate (31) of a support case (3). Fixation holes (32a) are created on the back plate (32). The joint (11) is inserted through the insertion hole (31a), and a slit press-fitting section (31c) is press-fitted to the slit section (112a). The fixation claws (22a, 23a) are inserted through the fixation holes (32a) and bent. The corners of the hexagonal section (112) of the joint (11) are swaged toward the support case (3).
