Problems solved by technology

[0004] Light-emitting / light-receiving components are usually formed by embedded (DIP) or surface-mounted (SMD). The embedded light-emitting / receiving components must be placed on the substrate first, and then placed manually The components are welded and fixed, which is prone to human error, resulting in loss of production capacity; the surface-mounted light emitting / receiving component is to place the chip directly on the substrate in a surface-mounted manner, and place the light emitting component and the light receiving component separately. In two different shells, the two shells are finally bonded, and the manufacturing process is quite complicated
[0005] Therefore, how to improve the combination of the photointerrupter and the housing, avoid the problem of operator error, simplify the process and reduce the probability of damaged products is the goal that manufacturers still need to work hard to solve.

Embodiment Construction

[0030] figure 1 and figure 2 It is a schematic diagram of the photointerrupter of the present invention, see figure 1 and figure 2 , The photointerrupter 1 includes a housing 10 and a light emitting / receiving unit.

[0031] The housing 10 is integrally formed and has a groove portion 11 and a first engaging portion 12 . The casing 10 includes a first casing 101 and a second casing 102, the first casing 101 and the second casing 102 respectively define a first groove 111 and a second groove 112, and the first groove 111 and the second groove 112 both include a first surface 113 and a second surface 114 opposite to the first surface 113, and the first engaging portion 12 includes a first sub-attachment 121 and a second sub-attachment The component 122 is respectively disposed on the second surface 114 of the first groove 111 and the second surface 114 of the second groove 112 .

[0032] The light emitting / receiving unit includes a light emitting component 13 , a light rec...

Abstract

The invention discloses a photo interrupter. The photo interrupter comprises a shell and a light emitting / receiving unit, the shell defines a groove part and is provided with a first clamping part arranged in the groove part, the light emitting / receiving unit is provided with a second clamping part, and when the light emitting / receiving unit is arranged in the groove part, the first clamping part and the second clamping part are clamped. Through the photo interrupter, the problem of the combining mode of the photo interrupter and an outer shell can be solved effectively.

Description

[0001] This application is a divisional application of the Chinese invention patent application 200910132561.6 filed on April 2, 2009 technical field [0002] The present invention relates to a photo-interrupter, and more specifically, relates to a photo-interrupter which can improve the convenience of assembly. Background technique [0003] The photointerrupter is composed of a light-emitting component and a light-receiving component. The light is emitted through the light-emitting component, and the light is received by the light-receiving component to generate a collector current. When an object passes between the light-emitting component and the light-receiving component , because the object blocks the passage of light, the collector current becomes smaller, and it can be known that there is an object passing through by detecting the change of the collector current. [0004] Light-emitting / light-receiving components are usually formed by embedded (DIP) or surface-mounted...
