Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, a schematic diagram of an embodiment of a waterproof sensor housing according to the present invention is shown. The utility model discloses a sensor housing includes casing 1, 1 one side of casing is detection mouth 2, 1 opposite side of casing is provided with cable cover 3, and circuit board 13 sets up in casing 1, and emitting diode connecting line board 13 is from detecting 2 external emission infrared light in the mouth, and cable 14 passes cable cover 3 and stretches into 1 in-connection circuit board 13 of casing. Refer to fig. 2 and show, do the utility model discloses an embodiment schematic diagram, because there is the clearance between cable 14 and the cable cover 3, consequently the sensor can't be sealed, if directly fill sealed glue to cable cover 3, then sealed glue spills over easily and causes the influence to emitting diode, scrap the sensor. Therefore, in this embodiment, a partition plate 4 is further provided, and the partition plate 4, the circuit board 13 and the metal sleeve 17 outside the circuit board 13 cooperate to surround the cable sleeve 3, so as to divide the housing 1 into the detection cavity 5 and the sealing cavity 6. Light emitting diode and circuit board 13 etc. all set up in detecting the chamber 5, and the cable 14 stretches out the position that cable cover 3 and is located sealed chamber 6, pours sealed glue into in sealed chamber 6, overlaps 3 totally sealings with the cable, and because the blockking of baffle 4, sealed glue can not spill over and cause the influence to light emitting diode etc.. The utility model discloses an in the embodiment one, the baffle is the shape of falling L board, the baffle sets up casing bottom surface just points to detect the offside of mouth. Thereby baffle and detection mouth form a space between the offside, and baffle and shell are further connected to circuit board 13 to baffle and circuit board divide into with the shell and detect chamber 5 and seal chamber 6, and the metal covering 17 of cover outside the circuit board further wraps up the protection with the circuit part of circuit board, can not influence the work of circuit board when guaranteeing to seal chamber injecting glue. In order to ensure the sealing between the partition plate and the shell, the partition plate and the shell are integrally formed by injection molding.

Referring to fig. 3, it is a schematic diagram of a second embodiment of the present invention, in this embodiment, in order to further prevent the influence of the sealant on the circuit board, the partition board is a flat plate, and in this way, the partition board and the housing cooperate to form a sealed cavity 6. In order to conveniently arrange a circuit board, a circuit board slot 7 is arranged on the partition board 4. The width of slot 7 is unanimous with circuit board 13's thickness, guarantees when the injecting glue in sealed chamber 6, and sealed glue can not reveal, and because circuit board 13 stretches into sealed chamber 6 in, cable 14 can be at sealed chamber 6 internal connection circuit board 13 to when sealed, 14 inner cores of cable 15 and overcoat 16's junction is sealed gluey parcel equally, further prevents that steam from getting into in 14 overcoat 16 of cable, influences 14's of cable life. In order to facilitate the insertion of the circuit board 13 into the slot 7, the open end of the slot 7 of the circuit board 13 is provided with a chamfer, and when the connection position of the cable 14 and the circuit board 13 is not in the sealed cavity 6, the cable 14 can also extend out of the chamfer to connect the corresponding position of the circuit board 13. If the length of the detection cavity 5 is enough to place the circuit board 13, in order to make the cable 14 extend out of the cable sleeve 3 and then be connected with the circuit board 13, a core wire hole is arranged on the partition board 4. Furthermore, the clapboard is provided with a core wire hole.

Referring to fig. 3, in the present embodiment, in order to adjust the sensitivity of the photosensor, an adjustment hole 8 is provided on one side of the housing 1, and an adjustment knob 9 is inserted into the adjustment hole 8 and abuts against the wiring board 13. Because there is the clearance in the junction of adjusting button 9 and regulation hole 8, the phenomenon of infiltration takes place easily, for solving this problem, in this embodiment, adjusting button 9 with be provided with sealing washer 10 between the regulation hole 8, 8 a week in regulation hole is provided with waterproof groove 11, the button cap of adjusting button 9 is down along being provided with to the bulge loop 12 that extends in the waterproof groove 11. When rainwater exists, the rainwater falls into the waterproof groove 11, and the height of the waterproof groove 11 is lower than that of the joint of the adjusting button 9 and the adjusting hole 8, so that the rainwater cannot enter the shell 1. In addition, rainwater is filled between the waterproof groove 11 and the convex ring 12, namely, a gap between the convex ring 12 and the waterproof groove 11 is filled with rainwater, at this time, a sealing space is formed among the water surface, the adjusting button 9, the shell 1 and the sealing ring 10, and due to the space sealing, along with the rising of the water surface, the sealing space formed by the adjusting button 9 and the shell 1 is extruded, the pressure intensity of the sealing space is increased, and the rainwater is further prevented from permeating.

Refer to fig. 4, be the utility model relates to an use sensor of above-mentioned waterproof sensor shell, the utility model discloses a sensor is still including detecting diode, circuit board 13 and cable 14 except above-mentioned shell, diode and circuit board 13 set up in detect in the chamber 5, the overcoat 16 of cable 14 penetrates cable cover 3, inner core 15 of cable 14 stretches into sealed chamber 6 is connected circuit board 13, sealed 6 intussuseption in chamber are filled with sealed glue. The detection diode connecting circuit board 13 is used for emitting light and receiving light, the cable 14 connecting circuit board is used for supplying power and the like, and due to the blocking of the partition plate 4, the sealant is only filled in the sealing cavity 6, so that the detection diode is not influenced. Because the outer sleeve 16 penetrates into the cable sleeve 3, the connection part of the inner core 15 and the outer sleeve 16 can be ensured not to be positioned outside the shell 1, and the possibility that rainwater and the like enter the cable 14 from the connection part of the inner core and the outer sleeve 16 is reduced. Further, in this embodiment, the sealant covers the joint between the inner core 15 and the outer sheath 16. Therefore, the connection part of the inner core 15 and the outer sleeve 16 is isolated from the outside, so that no water vapor enters the cable 14 from the connection part, the service life of the cable 14 is prolonged, and the service life of the sensor is prolonged.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
