Embodiment Construction
[0037] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.
[0038] refer to figure 2 , image 3 and Figure 4 , a first embodiment of the photoelectric switch of the present invention includes a light emitting member 2, a light receiving member 3, a rolling member 4, a first housing 5, and a second housing 6.
[0039] The light emitting element 2 includes an emitting portion 21 and a terminal portion 22 .
[0040] The light receiving element 3 includes a receiving portion 31 opposite to the emitting portion 21 via an optical path, and a terminal portion 32 .
[0041] The rolling element 4 is disposed between the light emitting element 2 and the light receiving element 3, and rolls between a light-shielding position blocking the light path and a non-shading position not blocking the light path.
[0042] The first housing 5 forms a first groove 51, and has a first base...

A photoelectric switch includes a light emitting part, a light receiving part, a rolling part, a first casing forming a first groove, and a second casing forming a second groove. The second housing is matched with the first housing to define a rolling chamber for accommodating the rolling element, an emission accommodating chamber for accommodating the light emitting element, and a receiving accommodating chamber for accommodating the light receiving element , and two light through holes respectively located at the opposite sides of the rolling chamber, the first groove and the second groove are combined to define the rolling chamber, and one of the light through holes communicates the rolling chamber and the emission accommodation chamber , and another light through hole communicates with the rolling chamber and the receiving accommodating chamber, thereby forming the light path from the emitting part to the receiving part. By combining the first shell and the second shell to form the rolling chamber and the light through hole, the assembly process is simpler and the cost is lower.
Description
technical field [0001] The invention relates to a switch, in particular to a photoelectric switch with simple assembly procedure and low cost. Background technique [0002] refer to figure 1 , is a tilt switch disclosed in US Patent No. US 6800841B1, which includes a housing 11, an upper cover 12, an embedded module 13, a light emitter 14, a light receiver 15, and a rolling element 16. [0003] By arranging the built-in module 13 to provide a closed optical channel between the light transmitter 14 and the light receiver 15, light leakage can be prevented, and the sensitivity of the switch action can be improved. However, due to the addition of the built-in module 13, It also increases the assembly process and cost. Contents of the invention [0004] The object of the present invention is to provide a photoelectric switch with simple assembly procedure and low cost. [0005] The photoelectric switch of the present invention comprises a light emitting part, a light recei...
