Abstract
Description
Technical Field
[0001] The present application relates to the technical field of button signal lights, and in particular to a button indicator signal light. Background Art
[0002] Button indicator lights are a common user interface element, widely used in various devices and systems to provide immediate visual feedback. These lights are typically associated with a button or switch. When a button is pressed or the switch changes state, the light will light up or go out, or change color, to inform the user that the action has been accepted or the current status.
[0003] There is a push button switch in the related technology, whose main structure includes a button seat, an indicator signal light and a control seat, and the indicator signal light is arranged between the button seat and the control seat; a button is movably arranged on the button seat, and the indicator signal light includes a lamp seat and a signal light arranged in the lamp seat, and a control mechanism electrically connected to the signal light is arranged in the control seat, and the control mechanism can control the opening and closing of the signal light; a triggering member for triggering the switch action inside the control mechanism is arranged on the lamp seat. When the button is pressed, the button will push the triggering member down, and then the switch arranged on the control mechanism will be pushed by the triggering member to connect the power supply circuit of the signal light, and then the signal light will be lit.
[0004] Regarding the above-mentioned indicator signal lights, the conductive ends of some signal lights are still screwed into the lamp holder by means of threaded connection. However, in a working environment with relatively severe vibration, the conductive ends of the signal lights are very likely to rotate and become loose. As the loosening of the signal lights becomes increasingly severe, the conductive ends of the signal lights will gradually separate from the conductive parts set in the lamp holder, which will eventually lead to poor contact of the signal lights, which will directly affect the normal use of the signal lights.

DETAILED DESCRIPTION
[0024] The present application is further described in detail below with reference to the accompanying drawings.
[0025] An embodiment of the present application discloses a button indicator light.
[0026] Reference Figure 1 、 Figure 2 as well as Figure 3 The push-button indicator light includes a lamp holder 1 and a signal lamp 2 mounted on the lamp holder 1. A receiving cavity 10 is formed within the lamp holder 1. A circuit board 3 is removably mounted within the receiving cavity 10. The shape of the circuit board 3 matches the shape of the receiving cavity 10. The circuit board 3 is placed within the receiving cavity 10 through an opening on one side of the receiving cavity 10. In this embodiment, the signal lamp 2 uses a light-emitting diode. The positive and negative electrodes of the signal lamp 2 are welded to the circuit board 3, and the signal lamp 2 and the circuit board 3 are electrically connected.
[0027] like Figure 2 、 Figure 3 As shown, a hollow protective tube 4 is integrally formed on the outer wall of lamp holder 1. One end of protective tube 4 communicates with accommodating cavity 10. When lamp holder 1 is assembled with the button holder, protective tube 4 is inserted into the button holder. Signal light 2 is inserted into and retained within protective tube 4. This not only protects signal light 2 but also helps to focus the light, thus enhancing the indication effect.
[0028] like Figure 3 、 Figure 4 As shown, two terminals 5 are welded and fixed to the circuit board 3, one on each side of the circuit board 3. A cover plate 6 is also removably mounted on the lamp holder 1 to cover the opening of the accommodating cavity 10. The cover plate 6 abuts against the terminals 5 and secures the terminals 5 and the circuit board 3 to the inner wall of the accommodating cavity 10.
[0029] like Figure 3 、 Figure 4 As shown, the cover plate 6 is integrally formed with a plurality of clips 60, located on both sides of the cover plate 6. The outer wall of the lamp holder 1 is formed with a plurality of slots 11 that communicate with the accommodating cavity 10. The clips 60 are respectively engaged with the corresponding slots 11, and the cover plate 6 is fixed to the lamp holder 1 through the engagement between the clips 60 and the slots 11.
[0030] like Figure 3 、 Figure 4 As shown, two groups of limiting strips 12 corresponding to the wiring terminals 5 are integrally formed on the inner side wall of the accommodating cavity 10. Each group of limiting strips 12 contains two limiting strips 12, and the two limiting strips 12 in the same group are symmetrically arranged on both sides of their corresponding wiring terminals 5. The length direction of the limiting strips 12 extends along the direction in which the circuit board 3 is inserted into the accommodating cavity 10. The limiting strips 12 in the same group are arranged opposite each other. The wiring terminals 5 are formed with limiting grooves 50 facing their respective relative limiting strips 12. The wiring terminals 5 are inserted between the limiting strips 12 on both sides along the length direction of the limiting strips 12 through the limiting grooves 50. The limiting strips 12 are respectively plugged into and matched with their respective relative limiting grooves 50, and the wiring terminals 5 are fixed in the accommodating cavity 10 under the restraint of the limiting strips 12 on both sides.
[0031] like Figure 3 、 Figure 4 As shown, a terminal 5 is threadedly connected to a terminal post 5, and the terminal post 51 is screwed into the terminal 5 at an angle, and one end of the terminal post 51 away from the terminal 5 extends to the outside of the lamp holder 1. The terminal post 51 arranged at an angle facilitates wiring and ensures that the wiring work can be carried out more smoothly. A wire pressing plate 510 is rotatably provided on the terminal post 51, and the wire pressing plate 510 is limited on the terminal post 51. A baffle 62 facing the wire pressing plate 510 is integrally formed on the cover plate 6, and the baffle 62 is blocked on the outside of the wire pressing plate 510. The terminal post 51 is limited on the terminal 5 under the blocking of the baffle 62. When the terminal post 51 is screwed outward, the baffle 62 can effectively prevent the terminal post 51 from detaching from the terminal 5.
[0032] like Figure 3 、 Figure 4As shown, two fixing bases 7 are integrally formed on the inner sidewalls of the lamp holder 1, symmetrically arranged on either side of the accommodating cavity 10. A threaded hole 70 extends through the fixing base 7, and the length of the threaded hole 70 aligns with the length of the protective tube 4. A clearance groove 61 is formed on the sidewall of the cover plate 6 facing the threaded hole 70. This clearance groove 61 facilitates the subsequent screwing of fasteners into the threaded hole 70. When the lamp holder 1 and the button holder are assembled, the fasteners are screwed into the threaded hole 70, thereby connecting and securing the lamp holder 1 to the button holder.
[0033] like Figure 3 、 Figure 4 As shown, a support plate 71 is integrally formed on the side wall of the fixing seat 7 facing the cover plate 6. The support plate 71 is in contact with the inner side wall of the cover plate 6. The support plate 71 can support the cover plate 6. When the outer side wall of the cover plate 6 is squeezed by external force, the support of the support plates 71 on both sides can further enhance the compressive strength of the cover plate 6, making it less likely to deform.
[0034] like Figure 3 、 Figure 4 As shown, a trigger member 8 is also movably provided on the fixed seat 7, and the trigger member 8 is movably provided on the fixed seat 7 along the length direction of the protective tube 4. The clearance groove 61 is located on the movable path of the trigger member 8, and two limit blocks 80 are integrally formed on the trigger member 8, and the limit blocks 80 are spaced apart along the sliding direction of the trigger member 8. The trigger member 8 is movably limited on its respective fixed seat 7 by the limit blocks 80. When the button provided on the button seat is pressed, the button will push the trigger member 8 downward, and then the switch provided on the control mechanism will be pushed by the trigger member 8 to connect the power supply circuit of the signal light 2, and the signal light 2 will be lit. The provision of the clearance groove 61 ensures that the cover plate 6 will not interfere with the sliding of the trigger member 8, so that the trigger member 8 can push the switch on the control mechanism to be triggered smoothly.
[0035] The implementation principle is as follows: By limiting and fixing the circuit board 3 within the accommodating cavity 10, the signal light 2 is extended into the protective tube 4, which is inserted into the button holder. The protective tube 4 not only protects the signal light 2, but also makes the light of the signal light 2 more concentrated, acting as a focusing light, thereby further improving the indication effect. The cover plate 6 is fixed to the lamp holder 1 through the mutual engagement of the clip 60 and the slot 11. At this time, the cover plate 6 can press the terminal block 5 and the circuit board 3 against the inner wall of the accommodating cavity 10. While improving installation efficiency, it also ensures the stability and reliability of the signal light 2 and the circuit board 3. Even in a working environment with severe vibration, the normal operation of the signal light 2 can be guaranteed. The connection between the signal light 2 and the circuit board 3 is not easily affected by the external harsh environment and fracture. The earthquake resistance of the signal light 2 is improved, and the stability of the signal light 2 in harsh environments is improved. The structure is stable, reliable, and more durable.
[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
