Description

Light sensor switch structure {LIGHT SENSING SWITCH STRUCTURE}

The present invention relates to an optical sensor, and more particularly, to an optical sensor switch structure installed on a circuit board or a flexible cable.

In the conventional photosensor device, since the connection pin is fixed, the circuit board has to be designed according to the position of the fixed connection pin. In addition, the length of the connection pin is limited, so that it is generally only installed at the proximal end of the circuit board and difficult to mount at the distal end.

Therefore, the circuit arrangement of the designer or the assembly of the assembler is hindered due to the fixed arrangement method, and when the optical sensor element is damaged, easy replacement or maintenance becomes difficult.

The present invention provides an optical sensor switch structure that can achieve the above object.

A first object of the present invention is to provide an optical sensor switch structure that can be installed on a circuit board or a flexible cable.

A second object of the present invention is to provide an optical sensor switch structure that can be easily installed on a circuit board or a flexible cable by changing the positions of connection pins (upper part, main body, and lower part) through the structure of the base body.

A third object of the present invention is to provide an optical sensor switch structure usable by being connected to the distal end by clamping the flexible cable with the recess and the packaging member and electrically connecting to the optical sensor module.

In order to achieve the above object and other objects, the present invention provides an optical sensor switch structure that is installed on a circuit board or a flexible cable. The photosensor switch structure includes a photosensor module, a base body, and a housing. The photosensor module includes a photodiode and a light emitting diode. The light emitting diode makes the light ray incident on the photodiode, and the photosensor module generates a first signal. The photosensor module generates a second signal when the light beam is blocked between the light emitting diode and the photodiode. The photosensor module further includes a first upper end, a first main body, a first lower end, a second upper end, a second main body, and a second lower end. A first upper end and a first lower end are connected to the first body. A photodiode is connected to the first upper end. The first lower end is connected to the circuit board or the flexible cable. The first upper end, the first body, and the first lower end are integrally formed. A second upper end and a second lower end are connected to the second body. A light emitting diode is connected to the second upper end. The second lower end is connected to the circuit board or the flexible cable. The second upper end, the second body, and the second lower end are integrally formed. An optical sensor module is provided on the base body. A first groove and a second groove are formed in the base body, and the first groove and the second groove are formed to correspond to each other. The first groove is for exit of the light beam, and the second groove is for incidence of the light beam. The housing is configured to package the photosensor module and the base body.

Compared with the prior art, the optical sensor switch structure provided by the present invention can implement a circuit design at the proximal end by changing the installation of the base body and the position of the connection pins through the arrangement of the circuit board. In addition, the present invention can implement a circuit design at the distal end by using a flexible cable through the arrangement of the groove and the packaging member.
