[0004] The purpose of the present invention is to provide a photosensitive sensor and its preparation process for the safety protection device of the switchgear. The clamping knife installed plays the role of limiting the thrust of the threaded rod. The outward thrust effectively protects the condenser lens, and solves the problem of damage to the condenser lens caused by excessive pressure due to incorrect estimation during manual operation

Embodiment 1
[0037] see Figure 1-4 Shown, the present invention is the photosensitive sensor that is used for switchgear safety protection device, comprises base 2, threaded rod 4, mount 5 and housing 10, and the upper end surface of base 2 is provided with a boss 201; One end of boss 201 A block 1 is provided, and the other end of the boss 201 is provided with a mounting seat 5; it is characterized in that:
[0038] One side of the mounting base 5 is provided with a through hole 501; the other side of the mounting base 5 is provided with a slot 502; the through hole 501 and the slot 502 are perpendicular to each other;
[0039] Among them such as image 3 As shown, the slot 502 includes a left slot and a right slot, and the internal features of the left slot and the internal features of the right slot are symmetrically distributed; the left slot is sequentially provided with studs from left to right 7. Elastic element 8, card knife 9;
[0040] One end of the threaded rod 4 passes thro...
Embodiment 2
[0048] Photosensitive sensor preparation process, its steps are as follows:
[0049] Step 1, adjust the screw-in depth of the studs 7 installed on the left and right sides of the mounting seat 5, so that the pressure of the elastic element 8 is in the range of 3MPa-5MPa;
[0050] Step 2, the housing 10 is placed on one side of the block 1, and the condensing lens 11 and the ultraviolet filter 12 coated with adhesive are sequentially bonded to the stepped hole 1001 provided on the housing 10. inside the opening;
[0051] Step 3 Place the lower port of the housing 10 on one side of the block 1, turn the handle 6, so that the push block 3 exerts a thrust on the top of the condenser lens 11, helping the adhesion of the condenser lens 11 and the ultraviolet filter 12 catch.
[0052] A specific application of this embodiment is: .

Abstract
The invention discloses a photosensitive sensor for a switch cabinet security protection device and a preparation technology thereof, and relates to the technical field of photosensitive sensor processing. The photosensitive sensor for a switch cabinet security protection device includes a base, a threaded rod, a mounting seat and a shell, a through hole is formed in one side face of the mountingseat, the other side face of the mounting seat is provided with a groove hole, the groove hole includes a left side groove hole and a right side groove hole, the left side groove hole is successivelyprovided with a stud, elastic elements and a clamping knife from left to right, one end of the threaded rod passes through the through hole and is installed in the middle position on one side face ofa pushing block, the other end of the threaded rod is provided with a handle through a pin shaft, the shell is installed between a retaining block and the pushing block, the shell is internally provided with a stepped hole, a condensing lens and an ultraviolet light filter are installed at the opening of the stepped hole, and the ultraviolet light filter is located on the inner side. According tothe photosensitive sensor for a switch cabinet security protection device and the preparation technology thereof, the action of limiting thrust of the threaded rod is played by installing the clampingknife, and the problem that excessive pressure causes damage to the condensing lens due to false estimation errors in the process of manual operation is solved.
Description
technical field [0001] The invention belongs to the technical field of photosensitive sensor processing, in particular to a photosensitive sensor used for a safety protection device of a switch cabinet and a preparation process thereof. Background technique [0002] Photosensitive sensor is one of the most common sensors. It has a wide variety, mainly including: photocell, photomultiplier tube, photoresistor, phototransistor, solar cell, infrared sensor, ultraviolet sensor, fiber optic photoelectric sensor, color sensor, CCD and CMOS image sensor, etc. [0003] The existing photosensitive sensors used for switchgear safety protection devices often increase the defective rate of products due to deliberate operations during the installation process, which cannot meet the existing use requirements. Contents of the invention [0004] The purpose of the present invention is to provide a photosensitive sensor and its preparation process for the safety protection device of the s...
