Description

Technical Field

[0001] This utility model belongs to the field of diode technology, specifically relating to a novel surface mount diode. Background Technology

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes: a positive terminal, also called the anode, and a negative terminal, also called the cathode. When a forward voltage is applied between the two terminals, the diode conducts; when a reverse voltage is applied, the diode is cut off. The conduction and cutoff of a diode are equivalent to the on and off states of a switch. Surface mount diodes are crystal diodes manufactured using surface mount technology (SMT). They have unidirectional conductivity and are widely used in electronic equipment for functions such as current control, rectification, and protection.

[0003] The existing protective cover is connected to the substrate by a locking block. Repeatedly pressing the protective cover and moving the locking block out of the slot can easily cause deformation and damage to the protective cover and the locking block, resulting in poor device practicality. In addition, the light-transmitting port on the existing protective cover is far away from the light-emitting part of the component. When the light-emitting part of the component emits light, the light transmission effect of the light-transmitting port is poor, which is not conducive to observation. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a novel surface mount diode, which features good fixation between the protective cover and the substrate, and facilitates quick assembly and disassembly of the protective cover.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel surface mount diode, comprising a substrate, an element mounted on the upper end of the substrate, a plurality of openings in the substrate, a protective cover on the upper side of the substrate, a light-transmitting opening in the protective cover corresponding to the element, a light-concentrating component at the lower end of the protective cover corresponding to the light-transmitting opening, and the protective cover and the substrate being connected by a connecting component.

[0006] The connecting assembly includes insert plates. Insert plates are fixed on both sides of the lower end of the protective cover. Slots are opened on both sides of the upper end of the base plate at positions corresponding to the insert plates. A cavity is opened in the base plate at a position corresponding to the slot. A sliding plate slides in the cavity. A locking rod is fixed at one end of the sliding plate near the slot. A spring is provided at the other end of the sliding plate. A protruding rod is fixed at the upper end of the sliding plate. A sliding groove corresponding to the protruding rod is opened at the upper end of the base plate. A connecting rod is fixed between the two protruding rods. A locking hole corresponding to the locking rod is opened at one end of the insert plate. Limiting components are provided on both sides of the upper end of the base plate at positions corresponding to the connecting rod.

[0007] Preferably, the limiting component includes a vertical plate, and vertical plates are fixed on both sides of the upper end of the base plate at positions corresponding to the connecting rod. A rotating shaft is rotatably connected to the upper side of one end of the vertical plate, and a baffle is fixed to the other end of the rotating shaft. A rubber pad is fixed to one end of the baffle at a position corresponding to the connecting rod.

[0008] Preferably, the side of the lever away from the slide plate is configured as an arc-shaped structure, and the side of the protruding lever is tangent to the inner wall of the slide groove, as is the side of the slide plate and the inner wall of the cavity.

[0009] Preferably, after the insert plate enters the slot, the side of the insert plate is in close contact with the inner wall of the slot, and the base plate has a sliding hole corresponding to the lever.

[0010] Preferably, the rotating shaft and the vertical plate are connected by a damped rotation, and the rubber pad and the baffle are fixed together by adhesive.

[0011] Preferably, the light-concentrating component includes a threaded cylinder, and a threaded cylinder is fixed at the lower end of the protective cover at a position corresponding to the light-transmitting opening. A vertical tube is threadedly connected to the threaded cylinder, and an external thread corresponding to the vertical tube is opened on the upper side of the surface of the vertical tube. A fixed bucket is fixed at the lower end of the vertical tube, and a reflective film is fixed on both the fixed bucket and the inner wall of the vertical tube.

[0012] Preferably, the reflective film is glued to both the fixed bucket and the vertical pipe, and the fixed bucket and the vertical pipe are a welded integral structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting a connecting component, allows the protective cover to slide in the groove via a connecting rod during installation. The protrusion drives the slide plate to move in the cavity, compressing the spring. Then, the protective cover is placed on the base plate, and the insert plates on both sides of the lower end of the protective cover are inserted into the slots. The connecting rod is released, and the spring extends to push one end of the locking rod at one end of the slide plate into the locking hole at one end of the insert plate, achieving the effect of limiting and fixing the insert plate and the protective cover. The connecting component provides a better fixing effect between the protective cover and the base plate and facilitates quick assembly and disassembly of the protective cover.

[0015] 2. This utility model, by setting a light-concentrating component, screws the vertical tube into the threaded cylinder. When light shines through the light-transmitting opening, the fixed bucket concentrates the light emitted from the light-transmitting opening. The fixed bucket and the vertical tube reflect the light back to the light-transmitting opening and then through. At the same time, a reflective film is fixed on the inner wall of the fixed bucket and the vertical tube to improve the light reflection effect. By setting a light-concentrating component, the light emitted from the light-transmitting opening can be concentrated and then passed through the light-transmitting opening, thereby improving the light transmission effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-6 The present invention provides the following technical solution: a novel surface mount diode, comprising a substrate 1, an element 5 mounted on the upper end of the substrate 1, a plurality of openings 6 in the substrate 1, a protective cover 3 on the upper side of the substrate 1, a light-transmitting opening 4 in the protective cover 3 corresponding to the element 5, a light-concentrating component 7 at the lower end of the protective cover 3 corresponding to the light-transmitting opening 4, and the protective cover 3 and the substrate 1 being connected by a connecting component 2.

[0026] The connecting component 2 includes a plug plate 22. The plug plate 22 is fixed on both sides of the lower end of the protective cover 3. The upper side of the substrate 1 has slots 23 at positions corresponding to the plug plate 22. The substrate 1 has cavities 26 at positions corresponding to the slots 23. A sliding plate 27 slides in the cavity 26. A locking rod 28 is fixed at one end of the sliding plate 27 near the slot 23. A spring 210 is provided at the other end of the sliding plate 27. A protruding rod 21 is fixed at the upper end of the sliding plate 27. A sliding groove 211 corresponding to the protruding rod 21 is provided at the upper end of the substrate 1. A connecting rod 25 is fixed between the two protruding rods 21. A locking hole 24 corresponding to the locking rod 28 is provided at one end of the plug plate 22. Limiting components 29 are provided at positions corresponding to the connecting rod 25 on both sides of the upper end of the substrate 1.

[0027] Specifically, the limiting component 29 includes a vertical plate 291. The vertical plate 291 is fixed on both sides of the upper end of the base plate 1 at positions corresponding to the connecting rod 25. A rotating shaft 292 is rotatably connected to the upper side of one end of the vertical plate 291. A baffle 293 is fixed to the other end of the rotating shaft 292. A rubber pad 294 is fixed to one end of the baffle 293 at a position corresponding to the connecting rod 25.

[0028] By adopting the above technical solution, it is not necessary to move the baffle 293 when pushing the connecting rod 25. The baffle 293 rotates on the vertical plate 291 through the rotating shaft 292. After the baffle 293 rotates to the side of the connecting rod 25, it can limit and block the connecting rod 25, thus avoiding accidental pushing of the connecting rod 25. The rubber pad 294 is fixed at one end of the baffle 293 at the position corresponding to the connecting rod 25 to play a buffering role.

[0029] Specifically, the side of the lever 28 away from the slide plate 27 is set as an arc structure, and the side of the protruding rod 21 is tangent to the inner wall of the slide groove 211 and the side of the slide plate 27 is tangent to the inner wall of the cavity 26.

[0030] By adopting the above technical solution, the side of the locking rod 28 away from the slide plate 27 is set with an arc structure to facilitate the insertion of one end of the locking rod 28 into the locking hole 24 at one end of the insert plate 22, and the sliding of the protruding rod 21 and the slide plate 27 in the slide groove 211 and the cavity 26 is more stable.

[0031] Specifically, after the insert plate 22 enters the slot 23, the side of the insert plate 22 is in close contact with the inner wall of the slot 23, and the base plate 1 has a sliding hole corresponding to the lever 28.

[0032] By adopting the above technical solution, after the insert plate 22 enters the slot 23, the insert plate 22 is more stable in the slot 23, and the locking rod 28 can slide in the base plate 1.

[0033] Specifically, the rotating shaft 292 and the vertical plate 291 are connected by damping rotation, and the rubber pad 294 and the baffle 293 are fixed by adhesive.

[0034] By adopting the above technical solution, the rotating shaft 292 is less likely to rotate on the vertical plate 291, and the glue bonding makes the rubber pad 294 more secure and less likely to fall off.

[0035] In this embodiment, when using the surface-mount diode, the device is installed in a suitable position. The protective cover 3 can protect the component 5 on the substrate 1. When the surface-mount diode is connected to the circuit, the component 5 will emit light, which is transmitted through the light-transmitting port 4. When installing the protective cover 3, the connecting rod 25 pushes the protruding rod 21 to slide in the slide groove 211. The protruding rod 21 drives the sliding plate 27 to move in the cavity 26, and the spring 210 is compressed. Then, the protective cover 3 is placed on the substrate 1, and the insert plates 22 on both sides of the lower end of the protective cover 3 are inserted into the slots 23. The connecting rod 25 is released, and the spring 210 extends to push one end of the locking rod 28 at one end of the sliding plate 27 into the slot. The insertion plate 22 and the protective cover 3 are fixed in the locking hole 24 at one end. The connection component 2 is set to fix the protective cover 3 and the base plate 1 better and facilitates quick disassembly and assembly of the protective cover 3. By setting the limiting component 29, the baffle 293 does not need to be moved when the connecting rod 25 is pushed. The baffle 293 rotates on the vertical plate 291 through the rotating shaft 292. After the baffle 293 rotates to the side of the connecting rod 25, it can limit and block the connecting rod 25 to avoid accidental pushing of the connecting rod 25. The rubber pad 294 is fixed at the position corresponding to the connecting rod 25 at one end of the baffle 293 to play a buffering role.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that: the light-concentrating component 7 includes a threaded cylinder 71, the lower end of the protective cover 3 is fixed with the threaded cylinder 71 at the position corresponding to the light-transmitting opening 4, the threaded cylinder 71 is threadedly connected to the vertical tube 72, the upper surface of the vertical tube 72 is provided with an external thread 75 corresponding to the vertical tube 72, the lower end of the vertical tube 72 is fixed with a fixed bucket 73, and the inner wall of both the fixed bucket 73 and the vertical tube 72 is fixed with a reflective film 74.

[0038] By adopting the above technical solution, the vertical tube 72 is screwed into the threaded cylinder 71. When the light-transmitting hole 4 is bright, the fixed bucket 73 focuses the light emitted from the light-transmitting hole 4. The fixed bucket 73 and the vertical tube 72 reflect the light to the light-transmitting hole 4 and let it pass through. At the same time, a reflective film 74 is fixed on the inner wall of the fixed bucket 73 and the vertical tube 72 to improve the light reflection effect. By setting the light-concentrating component 7, the light emitted from the light-transmitting hole 4 can be focused and let it pass through the light-transmitting hole 4, thereby improving the light transmission effect.

[0039] Specifically, the reflective film 74 is glued to the fixed bucket 73 and the vertical tube 72, and the fixed bucket 73 and the vertical tube 72 are welded as a whole.

[0040] By adopting the above technical solution, the adhesive bonding makes the reflective film 74 more firmly connected to the fixed bucket 73 and the vertical tube 72, and the fixed bucket 73 and the vertical tube 72 are welded into a whole structure, which is more robust and durable.

[0041] In this embodiment, the vertical tube 72 is screwed into the threaded cylinder 71. When light shines through the light-transmitting port 4, the fixed bucket 73 focuses the light emitted from the light-transmitting port 4. The fixed bucket 73 and the vertical tube 72 reflect the light back to the light-transmitting port 4 and allow it to pass through. At the same time, a reflective film 74 is fixed to the inner wall of the fixed bucket 73 and the vertical tube 72 to improve the light reflection effect. By setting the light-concentrating component 7, the light emitted from the light-transmitting port 4 can be focused and allowed to pass through the light-transmitting port 4, thereby improving the light transmission effect.

[0042] The structure and working principle of the substrate 1, protective cover 3, light-transmitting opening 4, element 5 and opening 6 in this utility model have been disclosed in a novel LED chip diode disclosed in Chinese patent application number 2024200767046.

[0043] The working principle and usage process of this utility model: When using the surface mount diode, the device is installed in a suitable position. The protective cover 3 can protect the component 5 on the substrate 1. When the surface mount diode is connected to the circuit, the component 5 will emit light, which is transmitted through the light-transmitting port 4. When installing the protective cover 3, the connecting rod 25 pushes the protruding rod 21 to slide in the sliding groove 211. The protruding rod 21 drives the sliding plate 27 to move in the cavity 26, and the spring 210 is compressed. Then, the protective cover 3 is placed on the substrate 1. The insert plates 22 on both sides of the lower end of the protective cover 3 are inserted into the slots 23. The connecting rod 25 is released, and the spring 210 extends and pushes the locking rod 28 at one end of the sliding plate 27 into the locking hole 24 at one end of the insert plate 22, thereby achieving the effect of limiting and fixing the insert plate 22 and the protective cover 3. The fixing effect between the protective cover 3 and the substrate 1 is better by setting the connecting component 2. To facilitate quick assembly and disassembly of the protective cover 3, a limiting component 29 is provided. When pushing the connecting rod 25, the baffle 293 is not required. The baffle 293 rotates on the vertical plate 291 via a pivot 292. After rotating to the side of the connecting rod 25, the baffle 293 can limit and block the connecting rod 25, preventing accidental pushing. A rubber pad 294 is fixed at one end of the baffle 293 corresponding to the connecting rod 25 to provide cushioning. The vertical tube 72 is screwed into the threaded cylinder 71. When light shines through the light-transmitting opening 4, the fixed bucket 73 focuses the light emitted from the light-transmitting opening 4. The fixed bucket 73 and the vertical tube 72 reflect the light back to the light-transmitting opening 4. Simultaneously, a reflective film 74 is fixed to the inner walls of the fixed bucket 73 and the vertical tube 72 to improve light reflection. By setting a light-concentrating component 7, the light emitted from the light-transmitting opening 4 can be focused and passed through the opening, improving light transmission.
