This application claims priorities from the Chinese patent applications 2022222179589 filed Aug. 23, 2022, and 2022226149987 filed Sep. 30, 2022, the content of which are incorporated herein in the entirety by reference.
The present disclosure relates to a lamp controller.
Because of its various shapes and flashing lights, festive string lights have lighting decorative effects at night, and are also the first choice for people to add festive atmosphere in festivals. The above lighting decoration effect sends a control signal with a duty ratio to an LED lamp through a controller, and the control signal makes the LED lamp generate various flashing effects.
As shown in
The installation sequence of the first LED lamp controller described above is as follows: first, the circuit board 1 is inserted into the accommodating cavity of the main housing 2 along the axial direction X of the main housing 2, and then the end cap 3 is covered. When the end cap 3 covers the housing 2, the output plug-in component 7 is inserted into and passes through the output connecting terminal 5 along the axial direction X of the output connecting terminal 5, and finally the end cap 3 and the main housing 2 are sealed by ultrasonic waves.
In the first LED lamp controller described above, the main housing 2 and the conductive component 4 therein are integrally molded by injection molding, and the main housing 2 does not need to be divided into several parts. Moreover, the plug-in socket 6 is not on the main housing 2, but on the end cap 3, that is, the plug-in socket 6 is separated from the main housing. Therefore, it is easy for the output plug-in component 7 to be plugged with the output connecting terminal 5 during assembly.
As shown in
The installation sequence of the second LED lamp controller described above is as follows: first, the circuit board is placed in the cavity of the upper housing 10, the clamping part 8 of the plug-in socket 6 is clamped into the first neck 13 of the upper housing 10, the power connecting terminal 9 is fitted with the second neck 14 of the upper housing 10, the connecting wire 7a is welded with the circuit board 1, and one end of the power connecting terminal 9 is welded with the circuit board 1.
The second LED lamp controller described above needs to weld the connecting wire 7a with the circuit board 1 during assembly, which has the disadvantage of time-consuming assembly. Welding materials are also required for welding, so that the second LED lamp controller also has the disadvantage of high cost. In addition, the existing clamping part 8 is circular, and the first neck 13 is also circular. Therefore, after installation, the clamping part 8 rotates with respect to the housing under the circumferential force, which will easily damage the welding parts between the connecting wire 7a and the circuit board 1.
The present disclosure provides a lamp controller, which can improve the assembly efficiency.
A lamp controller, comprising a circuit board, a main housing, a plug-in socket and an output plug-in component, wherein the main housing consists of an upper housing and a lower housing, the upper housing and/or the lower housing are provided with cavities, after the upper housing and the lower housing are combined, an accommodating cavity for assembling the circuit board is formed between the upper housing and the lower housing, the axial direction of the plug-in socket is not parallel to the longitudinal direction of the main housing, and the output plug-in component is fixed with the plug-in socket, wherein the controller further comprises an output connecting terminal, the output connecting terminal is fixed on the circuit board, the circuit board is provided with a yielding opening, a part of the output plug-in component is located in the cavity of the upper housing or the lower housing, after the plug-in socket is fixed with the main housing, when the circuit board is assembled into the cavity of the upper housing or the lower housing, the output connecting terminal is connected with the output plug-in component again after the end of the output plug-in component passes through the yielding opening on the circuit board.
The present disclosure is an improvement based on the second lamp controller in the background, which is combined with the state of fixing the plug-in socket and the main housing. After the output connecting terminal is added on the circuit board, the output connecting terminal is connected with the output plug-in component during assembly. This structure avoids the welding of the output connecting terminal and the output plug-in component, thus improving the assembly efficiency.
As shown in
The upper housing 10 and/or the lower housing 11 are provided with cavities 12. In this embodiment, preferably, the upper housing 10 and the lower housing 11 are both provided with cavities 12. After the upper housing 10 and the lower housing 11 are combined, an accommodating cavity for assembling the circuit board 1 is formed between the upper housing 10 and the lower housing 11, that is, the accommodating cavity consists of the cavity 12 on the upper housing 10 and the cavity 12 on the lower housing 11.
The plug-in socket 6 is fixed with the main housing 2. In this embodiment, preferably, the plug-in socket 6 and the upper housing 10 or the lower housing 11 are integrally formed, and the plug-in socket 6 and the upper housing 10 or the lower housing 11 are preferably integrally molded by injection molding. This structure does not need to separately clamp the plug-in socket 6 with the upper housing 10 or the lower housing 11 during subsequent assembly, which has the advantage of time-saving assembly. Furthermore, the structure that the plug-in socket 6 and the upper housing 10 or the lower housing 11 are integrally formed also has the advantages of good strength and excellent water resistance, which also avoids the unfavorable factors that the plug-in socket 6 rotates with respect to the main housing 2 to damage the connection between the output plug-in component 7 and the output connecting terminal 5 at the same time.
The axial direction X of the plug-in socket 6 is not parallel to the longitudinal direction Y of the main housing 2. In this embodiment, an included angle is formed between the axial direction X of the plug-in socket 6 and the longitudinal direction Y of the main housing 2, and the included angle is preferably 90 degrees.
In this embodiment, there are two output plug-in components 7. The two output plug-in components 7 can be connected with two-wire and two-channel LED lamps, such as the two-wire and two-channel string lamps disclosed in CN203523098U.
The output plug-in component 7 is fixed to the plug-in socket 6. Preferably, the plug-in socket 6 is provided with an assembly hole. One end of the output plug-in component 7 passes through the assembly hole, and the other end of the output plug-in component 7 fits inside the assembly hole, so that the plug-in socket 6 wraps a part of the output plug-in socket 7, the output plug-in socket 7 has a Y-shaped structure, and the other end of the output plug-in component 7 has an opening into which the input end of the lamp is inserted.
The lamp controller of this embodiment further comprises an output connecting terminal 5. The output connecting terminal 5 is fixed at the output end of the circuit board 1. The output connecting terminal 5 is welded to the output end of the control unit on the circuit board 1. The circuit board 1 is provided with a yielding opening 1a. One end of the output plug-in component 7 is located in the cavity 12 of the upper housing 10 or the lower housing 11. After the plug-in socket 6 is fixed with the main housing 2, when the circuit board 1 is assembled into the cavity 12 of the upper housing 10 or the lower housing 11, the output connecting terminal 5 is connected with the output plug-in component 7 after one end of the output plug-in component 7 passes through the yielding opening 1a of the circuit board 1.
Since the second lamp controller in the background is welded with the circuit board 1 and the output plug-in component 7 through the connecting wires 7a, respectively, the lamp controller in this embodiment is an improvement based on the second lamp controller in the background. Therefore, in order to improve the assembly efficiency, in this embodiment, after the connecting wire 7a in the prior art is eliminated, an output connecting terminal 5 is added to the circuit board 1. However, in this embodiment, the plug-in socket 6 is improved into a structure integrally formed with the upper housing 10 or the lower housing 11, and the output plug-in component 7 is integrally formed with the plug-in socket 6 by injection molding. Therefore, the output plug-in component 7 will not move during assembly. At this time, if the circuit board 1 is assembled in the cavity 12 on the upper housing 10 or the lower housing 11, the output plug-in component 7 will inevitably hinder the circuit board 1. Therefore, this embodiment has been improved. That is, the circuit board 1 is provided with a yielding opening 1a. When the circuit board 1 moves along the longitudinal direction Y of the upper housing 10 or the lower housing 11, so that the circuit board 1 is assembled into the cavity 12 of the upper housing 10 or the lower housing 11, one end of the output plug-in component 7 applies an acting force F in the longitudinal direction Y to the circuit board 1 or the output connecting terminal 5 (as shown in
It can be seen from the above that, in this embodiment, in order to improve the assembly efficiency, on the basis of the main housing 2 consisting of the upper housing 10 and the lower housing 11, the circuit board 1 is provided with a yielding opening 1a to yield the end of the output plug-in component 7, so that the output connecting terminal 5 is connected with the output plug-in component 7 for transmitting electrical signals.
Compared with the first lamp controller in the background, although both lamp controllers in this embodiment have the output connecting terminal 5 and the output plug-in component 7, this embodiment is different from the first lamp controller in the background in the above structure, and the most important difference is that the output connecting terminal 5 moves along the longitudinal direction Y of the upper housing 10 or the lower housing 11 when the acting force F is applied, so that the output connecting terminal 5 and the output plug-in component 7 are plugged or clamped. However, the first lamp controller in the background allows the output plug-in component 7 to be inserted into and pass through the output connecting terminal 5 along the transverse direction of the output connecting terminal 5 during assembly. Therefore, this embodiment is different from the first lamp controller in the background in assembly due to their different structural designs.
In this embodiment, according to the length of the yielding opening 1a, the following two manners are selected so that the output plug-in component 7 passes through the yielding opening 1a.
In this embodiment, the output connecting terminal 5 comprises a first clip 5a, a second clip 5b, and a connecting part 5c. One end of the first clip 5a is connected with one end of the connecting part 5c, and the other end of the connecting part 5c is connected with one end of the second clip 5b. A clearance space 5d fitted with the output plug-in component 7 is formed between the first clip 5a and the second clip 5b. The other end of the first clip 5a is fixed with the circuit board 1 and located at one side of the yielding opening 1a. The other end of the second clip 5b is fixed with the circuit board 1 and located at the other side of the yielding opening 1a. The clearance space 5d corresponds to the yielding opening 1a. The output plug-in component 7 generates expansion force on the first clip 5a and the second clip 5b after being inserted into the clearance space 5d.
Preferably, the other ends of the first clip 5a and the second clip 5b are bent to the outside of the clearance space 5d, so that the opening of the output connecting terminal 5 is tapered or splayed, which is beneficial for the output plug-in component 7 to enter the clearance space 5d. In addition, the output connecting terminal 5 may also use a U-shaped structure.
The output connecting terminal 5 with the above structure has the characteristics of simple structure, low cost and convenient assembly.
The lamp controller of this embodiment further comprises a power connecting terminal 9. The upper housing 10 and/or the lower housing 11 are provided with a clamping component 15 located outside the cavity 12. The clamping component 15 is provided with a neck 16, and a part of the power connecting terminal 9 is fitted with the neck 16.
In this embodiment, there is no power circuit on the circuit board 1, and the power supply is provided by an external independent power supply (not shown). Therefore, the lamp controller of this embodiment is an independent controller by configuring the power connecting terminal 9 to connect the external power supply.
In this embodiment, for the first side 1b of the circuit board 1 adjacent to the power connecting terminal 9, the distance H between the first side 1b and the adjacent inner walls of the upper housing 10 or the lower housing 11 is less than 3 mm.
Because the clamping component 15 is located outside the cavity 12, the clamping component 15 does not occupy the clearance space of the cavity 12, so that the space in the cavity 12 is used for installing the circuit board 1. Therefore, the size of the circuit board 1 can be made larger than that of the circuit board in the second lamp controller in the background, which is beneficial to expanding the circuit structure and avoiding the crowding of electronic components on the circuit board 1.
In this embodiment, the upper housing 10 is integrally formed with a first convex part 10a located outside the cavity 12. The lower housing 11 is formed with a first fitting groove 11a. The first convex part 10a is located on the end face covering the lower housing 11. The first fitting groove 11a is located on the end face covering the upper housing 10. The first fitting groove 11a is fitted with the first convex part 10a, and the plug socket 6 is integrally formed with the convex part 10a.
The convex part 10a is integrally formed with the upper housing 10, and the plug-in socket 6 is integrally formed with the convex part 10a, which prevents a part of the plug-in socket 6 from being arranged in the cavity 12. In this way, the plug-in socket 6 in this embodiment does not need to be provided with a clamping part, which prevents the plug-in socket 6 from occupying the space of the cavity 12, and is beneficial to expanding the size of the circuit board 1.
In this embodiment, the circuit board 1 is provided with a voice control mode input unit 17 for receiving external ambient sound. The upper housing 10 or the lower housing 11 is provided with a channel 18 through which external ambient sound reaches the voice control mode input unit 17. The channel 18 is fitted with the voice control mode input unit 17. The area where the channel 18 is located is flush with the surface of the upper housing 10 or the lower housing 11, or is convex or concave.
In this embodiment, in addition to the voice control mode input unit 17, various modes, such as input of a key 19 and input of remote control signals, can be used. There may be a single mode or a combination of two or more modes. After these input modes are processed by the control unit on the circuit board 1, these input modes are all converted into control signals for changing the loaded lamp. The above input modes form the prior art, which will not be described in detail here.
The assembly process of the lamp controller of this embodiment is as follows. Since the first convex part 10a and the upper housing 10 are integrally molded by injection molding, and the plug-in socket 6 and the first convex part 10a are integrally molded by injection molding, the plug-in socket 6 and the output plug-in component 7 are in a state of not moving during the assembly. Therefore, during assembly, when the circuit board 1 first moves along the longitudinal direction Y of the upper housing 10 and enters the cavity 12 of the upper housing 10, after one end of the output plug-in component 7 passes through the yielding opening 1a of the circuit board 1, the output plug-in component 7 is passively inserted into the clearance space 5d of the output connecting terminal 5, so that the output plug-in component 7 and the output plug-in component 7 are plugged and fixed. Then, the power connecting terminal 9 is clamped into the neck 16 of the clamping component 15, and the end of the power connecting terminal 9 is welded with the power input part of the circuit board 1. Finally, the lower housing 11 and the upper housing 10 are combined, and the combining part of the lower housing 11 and the upper housing 10 is welded by ultrasonic waves.
The present disclosure is not limited to the above embodiments, but the first embodiment can also have the following modifications.
When the plug-in socket 6 is fixed with the upper housing 10 or the lower housing 11 in the main housing 2, as shown in
For example, in this embodiment, after the included angle α is formed between the longitudinal direction Y1 of the circuit board 1 and the longitudinal direction Y of the upper housing 10 (Y direction is also the longitudinal direction of the main housing 2), first, the circuit board 1 is kept inclined and moves, the first side 1b is located between the output plug-in component 7 and the upper housing 10, and the end with the first side 1b is inserted into the gap between the output plug-in component 7 and the upper housing 10 in the state that the circuit board 1 is inclined to the upper housing 10. Then, the circuit board 1 is kept inclined and moves. For example, the movement can be a compound movement along the longitudinal direction Y of the main housing 2 and the axial direction of the plug-in socket 6, or a movement along the longitudinal direction Y of the main housing 2 alone, or a compound movement along the axial direction X of the plug-in socket 6 alone. Finally, the output connecting terminal 5 is connected with the output plug-in component 7.
The circuit board 1 in the second embodiment may not be provided with the yielding opening 1a.
As shown in
In this embodiment, preferably, the output connecting terminal 5 consists of a first clip 5a and a second clip 5b. A clearance space 5d fitted with the output plug-in component 7 is formed between the first clip 5a and the second clip 5b. One end of the first clip 5a and the second clip 5b is fixed to the circuit board 1. The other end of the first clip 5a and the second clip 5b is a free end. Therefore, an inserting opening 5e into which the output plug-in component 7 is inserted is formed between the other end of the first clip 5a and the other end of the second clip 5b.
In this embodiment, the plug-in socket 6 is separated from the main housing 2, which are not integrally molded by injection molding as in the first embodiment. Therefore, first, the circuit board 1 can be installed in the upper housing 10, and then the plug-in socket 6 can move in the direction indicated by the arrow on the dotted line in
The circuit board 1 in the third embodiment may not be provided with the yielding opening 1a.
The difference between this embodiment and the first embodiment is as follows. As shown in
Through the formed yielding space, there will be no interference when the plug-in component 7 is connected with the output connecting terminals 5. Especially when three output connecting terminals 5 are connected with three plug-in components 7, when one of the plug-in components 7 passes through the yielding space between two connecting terminals 5, the plug-in component 7 can be prevented from interfering with two output connecting terminals 5 arranged on both sides, thus increasing the convenience of assembly.
The middle of the second clip 5b is formed with a recess part 5f which is concave to the inside of the clearance space 5d. The concave part 5f further yields to the plug-in component 7 located in the middle, thus reliably ensuring that there is no interference problem. The extension part 5e is curved. For example, the extension part 5e is hook-like. The extension part 5e gets around to the front of the yield opening 1a.
In addition, in order to understand the structure of the present disclosure more clearly, that is, various input modes and output modes described above (mainly referring to the output plug-in component 7), more drawings are provided, specifically as shown in
