Technical Field
[0001] This utility model relates to the field of switch testing technology, specifically to a switch energization test bench. Background Technology
[0002] A switch is a component in electronic equipment used to connect, disconnect, and switch circuits. The principle of a switch is that a "closed" contact means the electronic contacts are conducting, allowing current to flow; an "open circuit" means the electronic contacts are not conducting, forming an open circuit and preventing current from flowing. A switch consists of a panel, current-carrying components, switch contacts, switch contacts, and a base. According to their application, switches are classified as toggle switches, band switches, record / playback switches, power switches, preset switches, and limit switches. According to their structure, switches are classified as micro switches, rocker switches, toggle switches, and sliding switches. Currently, switches require an electrical test during production, which involves measuring the number of times the switch is opened and closed.
[0003] For example, patent publication number CN211577346U discloses a switch energization test bench, including a rotary power device connected to a reciprocating swing device, which is detachably connected to a switch handle via a connecting structure. This invention has a simple structure and is easy to use, enabling rapid switching and allowing for the measurement of the number of times the switch can be switched, thus achieving automatic detection of the switch's usable lifespan, saving labor, and accelerating testing efficiency.
[0004] In the aforementioned patent, the inventor believes that although the patent verifies the upper limit of the number of times the switch can be turned on and off by using LEDs to illuminate the light, it uses a single LED to visually judge the switching on and off. When the LED is not lit, it is not possible to quickly determine whether the problem is with the lamp or the switch. Furthermore, when the switch malfunctions, the LED may remain lit or not light up at all. Therefore, the above test of the switch power-on has certain defects. Utility Model Content
[0005] To address this issue, the present invention provides a switch power-on test bench to solve the problems in the prior art where the use of a single LED light for visual judgment of switch operation leads to unclear test faults and inaccurate test data.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] See also Figures 1-4 This utility model provides a switch power-on test bench, including a workbench 1.
[0029] A support 2 is fixedly connected to the workbench 1, and a telescopic device 3 is fixedly mounted on the support 2.
[0030] The telescopic device 3 uses a telescopic motor as its power output device.
[0031] The bracket 2 is provided with an alternating telescopic assembly 4 connected to the telescopic device 3. The alternating telescopic assembly 4 includes a pair of slides 41, both of which are fixedly connected to the bracket 2. Each slide 41 is slidably connected to a slide plate 42. A toothed block group 43 is fixedly connected to the opposite surface of the pair of slide plates 42. A gear 44 is meshed on the pair of toothed block groups 43. The gear 44 is rotatably connected to the bracket 2 via a rotating shaft. The output end of the telescopic device 3 is fixedly connected to the top of one of the slide plates 42.
[0032] When the piston end of the telescopic device 3 reciprocates, it can drive one of the slide plates 42 to move vertically up and down on the slide block 41. In this application, the tooth block group 43 is composed of multiple vertically distributed tooth blocks. The vertical movement of one of the tooth block groups 43 synchronously with the slide plate 42 can mesh with the gear 44 to rotate, so that a pair of slide plates 42 can continue to move up and down alternately.
[0033] A pair of pressure posts 5 are provided on the alternating telescopic assembly 4. The pressure posts 5 are fixedly connected to the bottom end of the slide plate 42 and movably connected to the switch body 8.
[0034] By using a pair of sliding plates 42 to drive the corresponding pressure column 5 to continue to rise and fall alternately, the pair of pressure columns 5 can be used to alternately press and control the opening and closing ends of the switch to be tested.
[0035] A pair of proximity switches 6 are also provided on the bracket 2, and the proximity switches 6 are located on one side of the pressure column 5.
[0036] The proximity switch 6 uses the model LJM30T-10J / KS. The proximity switch 6 can count the frequency of the rise and fall of the pressure column 5 and detect its position. The frequency count can determine the upper limit of the number of times the switch under test can be opened and closed, and the position detection can determine whether the pressure column 5 is in the open or closed position of the switch under test.
[0037] A switch test stand 7 is provided on the workbench 1, and a switch body 8 is provided on the switch test stand 7.
[0038] In this application, the switch body 8 is a single-pole rocker switch.
[0039] The top of the switch test base 7 is provided with a switch slot 13 for the switch body 8 to be inserted.
[0040] By inserting the switch body 8 into the switch slot 13, the switch slot 13 can easily position the switch body 8 at the test position.
[0041] A connecting groove 14 is provided at the bottom of the inner side of the switch groove 13, and a conductive spring 15 is fixedly connected in each connecting groove 14. The conductive spring 15 is movably connected to the insert on the switch body 8.
[0042] When the switch body 8 is inserted into the switch slot 13, the conductive elastic material of the conductive spring 15 can easily and elastically abut against the insert of the switch body 8, so that the switch body 8 can be quickly connected to the test circuit.
[0043] The switch test base 7 is provided with a power line that is electrically connected to the switch body 8. The power line includes a live wire 9 and a neutral wire 10. One end of the live wire 9 passes through the switch test base 7 and is fixedly connected to one of the conductive springs 15. One end of the neutral wire 10 passes through the switch test base 7 and is fixedly connected to another conductive spring 15.
[0044] By connecting the live wire 9 and the neutral wire 10 to the corresponding terminals of the switch body 8, the switch body 8 can control the opening and closing of the circuit.
[0045] The lamp testing assembly 11 includes a lamp holder 111, which is fixedly connected to the workbench 1. A pair of lighting lamps 112 are mounted on the lamp holder 111. The pair of lighting lamps 112 are connected in parallel and then, as a whole load, are connected in series with the switch body 8 into an AC circuit consisting of a live wire 9 and a neutral wire 10. Specifically, one end of the parallel lighting lamp assembly is connected to one output terminal of the switch body 8 via a wire, and the other end is connected to the neutral wire 10.
[0046] When one of the pressure pins 5 presses the open end of the switch body 8, the circuit connected to the switch body 8 is energized, and the pair of lights 112 will light up, indicating that the switch body 8 is working normally. If one light 112 is lit and the other is not lit, it also indicates that the switch body 8 is working normally. If both lights 112 are not lit at the same time, the fault of the switch body 8 is more obvious. When the other pressure pin 5 presses the closed end of the switch body 8, the circuit connected to the switch body 8 is de-energized, and the light 112 will turn off, indicating that the switch body 8 is working normally.
[0047] The lamp testing assembly 11 is provided with a pair of lamp inspection assemblies 12. The lamp inspection assembly 12 includes a lamp cover 121, which is detachably connected to the lamp holder 111 and is located on the outside of the lighting lamp 112. A photoresistor 122 is fixedly connected to the top of the lamp cover 121, and the detection end of the photoresistor 122 extends into the lamp cover 121.
[0048] In this application, the lampshade 121 can be installed with the lamp holder 111 by screw connection, which makes it easy to disassemble the lampshade 121 to replace the lighting lamp 112. The photoresistor 122 is of model GL3516. The lampshade 121 is made of opaque material. When the power line controlled by the switch body 8 is in the energized state, that is, when one pressure post 5 is pressed on the open end of the switch body 8, the lighting lamp 112 should be in the lighting state. If the photoresistor 122 cannot detect the light source of the lighting lamp 112, the number of times the switch body 8 can be opened and closed is at the maximum state. If the other pressure post 5 is pressed on the closed end of the switch body 8, when the photoresistor 122 detects the light source of the lighting lamp 112, the number of times the switch body 8 can be opened and closed is also at the maximum state.
[0049] In this invention, the photoresistor 122, the telescopic device 3, and the proximity switch 6 can all be controlled and processed by existing control processors. The controller can also be connected to a digital display screen to display data on the workbench 1. The control processing circuit of the control processor can be implemented by simple programming by those skilled in the art, and the wiring method is also common knowledge in the art.
[0050] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
