Description
Technical Field
[0001] This utility model relates to the field of lighting control technology, and in particular to a waterproof structure for a lighting controller. Background Technology
[0002] A lighting controller is used to control lighting fixtures, such as controlling the switching on and off of the lights and adjusting their lighting effects. A lighting controller typically consists of a housing and a circuit board mounted inside the housing. The circuit board contains appropriate electrical components according to usage requirements. Moisture and humidity are common causes of malfunctions in the circuit board and its components. To prevent moisture from penetrating the circuit board and components and to prevent short circuits, the housing is a necessary design element to protect the circuit board.
[0003] like Figure 1 The lighting controller shown includes a circuit board 1, a main housing 2, a connector 6, an output connector 7, a connecting wire 7a, and a wire clip 9. The circuit board 1 has a control unit. This type of controller does not have a power supply circuit on the circuit board 1; the power supply is provided by an external independent power source (not shown). This type of controller without a power supply circuit is also called an independent controller. The main housing 2 consists of an upper housing 10 and a lower housing 11, each with a cavity 12. When the upper housing 10 and lower housing 11 are closed, a receiving cavity is formed between them. The circuit board 1 is located within this receiving cavity and is connected to the connector. One end of the base 6 is provided with a snap-fit part 8. The upper housing 10 and the lower housing 11 are respectively provided with first snap-fit slots 13. After the snap-fit part 8 is engaged with the first snap-fit slot 13, a part of the snap-fit part 8 is located in the cavity 12. The output plug-in component 7 is fixed on the plug-in base 6. One end of the output plug-in component 7 is connected to one end of the connecting wire 7a. The other end of the connecting wire 7a is electrically connected to the circuit board 1. The upper housing 10 and the lower housing 11 are respectively provided with second snap-fit slots 14. The wire clip 9 is engaged with the second snap-fit slot 14. One end of the wire clip 9 is electrically connected to the circuit board 1. The other end of the wire clip 9 is used to connect to an external independent power supply.
[0004] For the second type of LED light controller mentioned above, the installation sequence is as follows: First, place the circuit board in the cavity of the upper housing 10. Then, insert the snap-fit part 8 on the connector 6 into the first slot 13 on the upper housing 10. Next, engage the wire clip 9 with the second slot 14 on the upper housing 10. Finally, solder the connecting wire 7a to the circuit board 1 and solder one end of the wire clip 9 to the circuit board 1. After closing the upper housing 10 and the lower housing 11, weld the joint between the upper housing 10 and the lower housing 11 using ultrasonic welding.
[0005] For the above structure, since the material of the upper shell 10 and the lower shell 11 is usually PVC, and the material of the clamping part 8 and the wire clamp 9 is usually rubber, when ultrasonic welding is used due to the different materials of these parts, the clamping part 8 cannot be welded with the upper shell 10 and the lower shell 11, and the wire clamp 9 cannot be welded with the upper shell 10 and the lower shell 11. The sealing performance between the clamping part 8 and the upper shell 10 and the lower shell 11 relies on the cooperation between the clamping part 8 and the upper shell 10 and the lower shell 11. Similarly, the sealing performance between the wire clamp 9 and the upper shell 10 and the lower shell 11 relies on the cooperation between the wire clamp 9 and the upper shell 10 and the lower shell 11. However, as the clamping part 8 or the wire clamp 9 gradually ages, the sealing performance will eventually decrease, which poses a risk of short circuit to the circuit board 1 and the electrical elements. Technical scheme
[0006] The utility model provides a waterproof structure of lamp controller which has improved sealing performance.
[0007] The technical scheme for solving the above technical problem is as follows:
[0008] The waterproof structure of the lamp controller comprises a first shell, a second shell and a first wire clamp, the first shell has a first cavity, the first shell is provided with a first clamping part, the second shell has a second cavity, the second shell is provided with a second clamping part, a part of the first wire clamp is located in the first cavity and the second cavity, the first wire clamp is clamped between the first shell and the second shell after cooperating with the first clamping part and the second clamping part, and the waterproof structure further comprises a second wire clamp, the second wire clamp is located between the first shell and the second shell, and the second wire clamp is fixed to the first shell and the second shell.
[0009] In the utility model, the first wire clamp and the second wire clamp are fixed to the first shell and the second shell, respectively, so that a first seal is formed between the first wire clamp and the first shell and the second shell, and a second seal is formed between the second wire clamp and the first shell and the second shell. Through multiple seals, the sealing performance is improved, and the stability of the wire is increased through the combination of the first wire clamp and the second wire clamp with the first shell and the second shell.
[0010] In addition, the gap between the first wire clamp and the first clamping part and the second clamping part is sealed by the sealing glue, and the first cavity and the second cavity are sealed, so that liquid cannot enter the first cavity and the second cavity through the gap between the first wire clamp and the first clamping part and the second clamping part, and liquid cannot enter the first cavity and the second cavity through the gap between the cover plate and the opening, thereby avoiding the entry of liquid into the first cavity and the second cavity. Therefore, the sealing performance of the utility model is improved. BRIEF DESCRIPTION OF DRAWINGS

[0029] First embodiment
[0030] As shown in Figures 2 to 10 The waterproof structure of the lamp controller of the present embodiment comprises a first shell 100, a second shell 101, a first wire clamp 102, and a second wire clamp 109. The first shell 100 has a first cavity 103 therein, and the second shell 101 has a second cavity 105 therein. In the present embodiment, a first partition component 100a is arranged in the first shell 100, and the first cavity 103 is formed between the first partition component 100a and the end of the first shell 100. A second partition component 101c is arranged in the second shell 101, and the second cavity 105 is formed between the second partition component 101c and the end of the second shell 101.
[0031] The second wire clamp 109 is located between the first shell 100 and the second shell 101, and cooperates with the first partition component 100a and the second partition component 101c respectively. The wire 300 passes through the second wire clamp 109, and is fixed with the second wire clamp 109. In this way, the welding between the wire 300 and the circuit board 200 can be further prevented from being damaged by tension.
[0032] In the present embodiment, the first partition component 100a and the second partition component 101c are both two. A first accommodating cavity 100b is formed between the two first partition components 100a and the first shell 100, and a second accommodating cavity 101e is formed between the two second partition components 101c and the second shell 101. The first accommodating cavity 100b and the second accommodating cavity 101e are used to accommodate the circuit board 200 and electronic components (such as resistors, capacitors, etc.) mounted on the circuit board 200.
[0033] The first shell 100 is provided with a first clamping portion 104, which is a groove matching the peripheral surface of the first wire clamp 102. The second shell 101 is provided with a second clamping portion 106, which is a groove matching the peripheral surface of the first wire clamp 102. The material of the first wire clamp 102 is preferably rubber. The wire 300 passes through the first wire clamp 102 and is fixed with the first wire clamp 102. The wire 300 is welded with the circuit board 200.
[0034] When the first shell 100 and the second shell 101 are combined, a part of the first line card 102 and the second line card 109 is located in the first cavity 103 and the second cavity 105, another part of the first line card 102 is located outside the first shell 100 and the second shell 101, and the first line card 102 is clamped between the first shell 100 and the second shell 101 after the first line card 102 cooperates with the first card joint 104 and the second card joint 106. The clamping effect of the first shell 100 and the second shell 101 on the first line card 102 prevents the first line card 102 from moving axially, thereby avoiding that the lead wire 300 welded with the circuit board 200 is pulled to cause welding failure.
[0035] Further, the second shell 101 is provided with an opening 108 penetrating the second cavity 105, and the opening 108 is used for injecting sealant into the first cavity 103 and / or the second cavity 105 after the first shell 100 and the second shell 101 are combined, and the sealant is preferably epoxy glue. The cover plate 107 cooperates with the opening 108, and the cover plate 107 is fixed to the second shell 101.
[0036] In the embodiment, the sealant is used to seal the gap between the first line card 102 and the first card joint 104 and the second card joint 106, and to seal the first cavity 103 and the second cavity 105, thereby avoiding that liquid enters the first cavity 103 and the second cavity 105 through the gap between the first line card 102 and the first card joint 104 and the second card joint 106, and avoiding that liquid enters the first cavity 103 and the second cavity 105 through the gap between the cover plate 107 and the opening 108, and further avoiding that liquid enters the first accommodating cavity 100b and the second accommodating cavity 101e.
[0037] The utility model also includes cover plate 107, cover plate 107 includes cover plate body 107a, elastic buckle 107b, elastic buckle 107b is a plurality of, cover plate body 107a and elastic buckle 107b are through injection molding integrated, the second shell 101 is equipped with support 101a in, and the inner wall of second shell 101 is equipped with buckle joint 101b, and after cover plate 107 cooperates with opening 108, support 101a forms the support to cover plate body 107a, and elastic buckle 107b cooperates with buckle joint 101b.
[0038] The buckle part 101b is a groove, and the buckle part 101b corresponds to the support 101a, and an assembly space 101d for inserting the elastic buckle 107b is formed between the buckle part 101b and the support 101a. During installation, the elastic buckle 107b is deformed by extrusion between the support 101a and the inner wall of the second shell 101 when passing through the assembly space 101d, and when the elastic buckle 107b is fed to correspond to the buckle part 101b, the elastic buckle 107b is no longer extruded due to the accommodation of the buckle part 101b to the elastic buckle 107b, and the elastic buckle 107b is reset, so that the elastic buckle 107b and the buckle part 101b form a buckling effect. This buckling structure makes the assembly of the cover plate 107 and the second shell 101 convenient, saves time and cost.
[0039] The cover plate 107 further comprises a plug-in part 107c fixed with the cover plate body 107a, and the plug-in part 107c enters the second cavity 105 through the opening 108 and cooperates with the inner wall of the second shell 101. In the embodiment, the number of elastic buckles 107b is preferably two, and the number of plug-in parts 107c is preferably one. During installation, the plug-in part 107c is first inserted into the second shell 101 through the opening 108, and then the elastic buckle 107b passes through the assembly space 101d to form a buckle with the buckle part 101b.
[0040] The embodiment further comprises a touch button 110 and an indicator light 111, and the first shell 100 is provided with a first mounting hole 112, a second mounting hole 113 and a sound pickup hole 114. The touch button 110 cooperates with the first mounting hole 112, and the indicator light 111 cooperates with the second mounting hole 113. The touch button 110 cooperates with the circuit board 200, and the indicator light 111 is electrically connected with the circuit board 200. The circuit board 200 is provided with a sound pickup device corresponding to the sound pickup hole 114.
[0041] Second embodiment
[0042] The utility model is not limited to the above-mentioned embodiments, for example, the fixing of the cover plate 107 and the second shell 101 can also adopt the following structure: further comprising a screw, the second shell 101 is provided with a support 101a, and the cover plate 107 cooperates with the opening 108, and the cover plate 107 is fixed with the support 101a by the screw. The screw is used to fix the two, and since the process of screwing the screw needs to be added, the convenience is relatively lower than the buckling mode in the first embodiment.
