DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5The utility model provides a technical solution: a waterproof diode, including a diode body 1, a pin 2 is fixedly connected to the bottom of the diode body 1, a waterproof component 3 is connected to the outside of the diode body 1, and the waterproof component 3 includes a fixed column 301, the fixed column 301 is fixedly connected to the diode body 1, and a sleeve 302 is slidably connected to the outside of the fixed column 301, a storage cavity 303 is opened in the sleeve 302, and a film 304 is overlapped in the storage cavity 303, the film 304 is filled with sealant 308, and the material of the sealant 308 is epoxy AB glue, a pointed cone 305 is fixedly connected in the storage cavity 303, a slide rail 306 is opened on the inner wall of the sleeve 302, and a slider 307 is slidably connected in the slide rail 306, and the slider 307 moves along the sleeve 30 2 is symmetrically arranged at the center, the slider is fixedly connected to the fixed column 301 on the outside, and the film 304 is overlapped with the pin 2. By setting the slide rail 306 and the slider 307, the sleeve 302 is ensured to move along the slide rail 306. By setting the sleeve 302 and the fixed column 301, the sleeve 302 is slid along the slide rail 306, so as to facilitate the contraction of the fixed column 301 into the sleeve 302. By setting the pointed cone 305, a force is applied to the film 304, so that the pointed cone 305 pierces the film 304. By setting the sealant 308, the pin 2 is coated with the sealant 308, so as to achieve a waterproof effect and have a heat conductive function. By setting the film 304 and the storage cavity 303, the sealant 308 is conveniently stored.

[0026] A sealing strip 4 is bonded inside the fixing column 301 , and the outside of the sealing strip 4 overlaps with the diode body 1 . A groove 5 is provided inside the sleeve 302 . The sealing strip 4 facilitates sealing between the fixing column 301 and the diode body 1 .

[0027] Water-absorbent cotton 6 is bonded in the groove 5, and a waterproof rubber pad 7 is bonded under the water-absorbent cotton 6. The waterproof rubber pad 7 is bonded to the groove 5 on the outside. By arranging the water-absorbent cotton 6 and the waterproof rubber pad 7, it is convenient to seal between the sleeve 302 and the fixed column 301. At the same time, the water-absorbent cotton 6 is convenient for absorbing water to prevent water from contacting the pin 2.

[0028] A slide groove 8 is provided in the fixed column 301, and a limiting column 9 is slidably connected in the slide groove 8. Two limiting columns 9 are symmetrically arranged along the center of the fixed column 301. A reset spring 10 and the limiting column 9 are provided. When the reset spring 10 maintains the original length, the reset spring 10 pushes the limiting column 9 to extend, thereby limiting the sleeve 302. When the reset spring 10 is compressed, the limiting column 9 shrinks into the slide groove 8, thereby releasing the limitation on the sleeve 302.

[0029] One end of the limiting column 9 is fixedly connected with a return spring 10, and one end of the return spring 10 is fixedly connected with the inside of the slide groove 8, and the shape of one end of the limiting column 9 is arc-shaped.

[0030] The cleaning component 11 is connected to the outside of the sleeve 302, and the cleaning component 11 includes a second slide groove 1102, which is opened outside the sleeve 302, and two second slide grooves 1102 are symmetrically arranged along the outside of the sleeve 302. By setting the second slide groove 1102, it is convenient to slide the baffle 1101 along the second slide groove 1102.

[0031] A baffle 1101 is slidably connected to the inside of the slide groove 1102, and a cross bar 1103 is fixedly connected to the inside of the baffle 1101, a cleaning cotton 1104 is bonded to the inside of the cross bar 1103, and the cross bar 1103 is sleeved with the pin 2, the outside of the cleaning cotton 1104 is an inclined surface, and a slider 2 1105 is fixedly connected to the outside of the cross bar 1103. By setting the cross bar 1103 and the cleaning cotton 1104, when the cross bar 1103 drives the cleaning cotton 1104 to move, the cleaning cotton 1104 moves along the pin 2, thereby cleaning the pin 2.

[0032] The slide rail 306 is slidably connected to the slider 1105, the slide groove 1102 is connected to the waterproof pad 12, and the sleeve 302 is snap-connected with a waterproof rubber ring 13. By providing the waterproof pad 12 and the waterproof rubber ring 13, the sealing between the baffle 1101 and the sleeve 302 is ensured.

[0033] Working principle: when the diode is used, firstly, the baffle 1101 is slid along the second slide groove 1102 to drive the baffle 1101 to move, and at the same time drive the cross bar 1103 to move, so that the cross bar 1103 drives the cleaning cotton 1104 to clean the pin 2, thereby ensuring the cleanliness of the pin 2, thereby facilitating the welding of the pin 2, preventing the pin 2 from loosening, and ensuring the use of the diode. Secondly, the pin 2 is welded by the welding gun. When the reset spring 10 maintains its original length, the reset spring 10 pushes the limit column 9 to extend, so that the limit column 9 overlaps the sleeve 302, thereby achieving the limit of the sleeve 302, preventing the fixed column 301 from applying force to the film 304, thereby ensuring the use of the film 304, and then releasing the limit column 9 on the sleeve 302, and sliding the sleeve 302 along the direction of the slide rail 306, so that the fixed column 301 applies pressure to the film 304, so that the film 304 is pressed by the sharp cone 305. The sealant 308 in the film 304 is punctured, so that the sealant 308 flows out, and the sealant 308 flows out along the card hole, and the card hole is sleeved with the pin 2, and the sleeve 302 is continuously pushed to continuously extrude the sealant 308 in the film 304, so that the sealant 308 covers the pin 2, thereby isolating the pin 2, thereby achieving a waterproof effect, ensuring the use of the diode body 1, and at the same time making the slider 1 307 overlap with the slider 2 1105, when the sleeve 302 moves, the slider 1 307 pushes the slider 2 1105 to move along the slide rail 306, so that the baffle 1101 overlaps with the circuit board, and at the same time prevents the sealant 308 from flowing out of the baffle 1101, when the limiting column 9 moves to the slide rail 306, the elasticity of the reset spring 10 is restored, and the limiting column 9 is pushed to engage with the slide rail 306, so as to limit the sleeve 302 and prevent the sleeve 302 from moving, thereby completing the use of the diode.

[0034] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
