Description

Technical Field

[0001] This utility model relates to the field of electrical control switch testing technology, specifically to a three-in-one switch testing fixture. Background Technology

[0002] With the rapid development of smart home, industrial automation, and IoT technologies, infrared switches, sound and light switches, and tactile delay switches, as core control components, are widely used in lighting control, security systems, home appliances, and public facilities. For example, external sensor switches are automatic control switches based on infrared sensing technology. They achieve their automatic control function by sensing infrared heat emitted from the outside environment, enabling them to quickly turn on lights and other electrical devices. Sound and light switches are triggered by changes in sound and light (such as ambient light intensity thresholds). Tactile delay switches are triggered by physical contact (such as buttons or touch) and have a delayed shut-off function. These three types of switches have significantly different functional characteristics, and their reliability, sensitivity, and safety must be ensured through rigorous switch performance testing before leaving the factory. Currently, the industry commonly uses dedicated testing equipment for each type of switch. Testers need to frequently switch equipment and repeatedly rewire, resulting in a cumbersome, time-consuming, and labor-intensive process. Therefore, traditional testing methods suffer from low efficiency, high cost, and complex operation. Utility Model Content

[0006] The test assembly includes a sound source generator, a light source generator, and an infrared generator installed inside the test chamber, and a timer installed outside the test chamber for detecting the delayed disconnection time of the test switch, as well as a load indicator light electrically connected to the test switch. The load indicator light and the test switch are connected through a pin assembly to form a load electrical circuit.

[0007] The control console, located at the bottom of the test chamber, includes a start button for controlling the movement and switching of the pin assembly between a first state and a second state, and control components electrically connected to the sound source generator, light source generator, infrared generator, and counter, respectively.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Example

[0028] This utility model provides, for example Figure 1-2 The three-in-one switch testing fixture shown includes:

[0029] The test chamber 1 includes a receiving cavity and a positioning seat 3 and a ejector pin assembly 4 disposed at the bottom of the receiving cavity. A test switch opposite to the ejector pin assembly 4 is positioned and installed on the positioning seat 3. The ejector pin assembly 4 is elastically movable on one side of the positioning seat 3. Since the test switch has a terminal hole that mates with the ejector pin assembly 4, and the ejector pin assembly 4 is connected to the test circuit, the power is turned on to the test switch by inserting the ejector pin assembly 4 into the terminal hole. Therefore, the ejector pin assembly 4 has a first state of moving out and making electrical contact with the test switch, and a second state of moving back and disconnecting from the test switch. In this embodiment, the test switch is any one of an infrared sensor switch, a tactile delay switch, and an audio-visual sensor switch.

[0030] The test assembly includes a sound source generator 5, a light source generator 6, and an infrared generator 7 installed inside the test box 1, and a timer 9 installed outside the test box 1 for detecting the delayed disconnection time of the test switch, and a load indicator light 8 electrically connected to the test switch. The load indicator light 8 and the test switch are connected to form a load electrical circuit through a pin assembly 4.

[0031] The control console 2 is located under the test box 1. It includes a start button 21 for controlling the movement and switching of the pin assembly 4 between the first state and the second state, and control components that are electrically connected to the sound source generator 5, the light source generator 6, the infrared generator 7 and the counter respectively.

[0032] The above-described implementation method is the core technical solution of this embodiment. The test switch is positioned and installed on the positioning seat 3 inside the test box. Then, the start button 21 on the control panel 2 is pressed. The pop-out ejector pin assembly 4 is moved to make electrical contact with the test switch, thereby powering the test switch. The corresponding sound source / light source / infrared generator and timing system are activated according to the different types of test switches. The illumination of the load indicator light 8 is then observed to determine whether the test switch meets the test qualification standard. The advantage of this technical solution is that by setting the sound source / light source / infrared generator and timing system inside and outside the test box, a closed test box is constructed to ensure accurate and controllable test conditions and reduce external interference. This integrates three control methods: infrared sensing, sound and light sensing, and light touch triggering (manual touch start), covering different scenario requirements and improving the controllability of the test environment. It can be seen that this three-in-one switch test fixture integrates the test requirements of infrared, sound and light, and light touch delay switches, eliminating the efficiency bottleneck caused by the separation of dedicated equipment in traditional testing, unifying the test platform, which is conducive to improving test efficiency, reducing test costs, reducing human error, and improving product quality.

[0033] To address the issues of frequent test switch switching and repetitive wiring operations, a flexible, movable ejector pin assembly 4 is designed to insert into the terminal hole of the test switch, achieving electrical contact between the ejector pin assembly 4 and the test switch. This design not only allows for rapid connection and testing of different types of test switches and ensures reliable electrical contact, but also automatically disconnects power and isolates the ejector pin assembly 4 when it is retracted. This design enables plug-and-play operation with zero wiring. The flexible extension and retraction stroke of the ejector pin assembly 4 can adapt to the terminal holes of these three types of test switches, eliminating the need for manual adjustment of the fixture and optimizing the complexity of the testing process.

[0034] As a preferred embodiment, refer to Figure 2 The positioning base 3 has a positioning groove 31 for installing the test switch. One side of the positioning groove 31 has a clearance opening opposite to the ejector pin assembly 4. The positioning groove 31 positions the test switch within it. The ejector pin assembly 4 includes multiple elastic ejector pins arranged side-by-side. When driven to move towards the clearance opening, these elastic ejector pins are inserted into the terminal holes of the test switch. This structure automatically completes the circuit connection after the elastic ejector pins are aligned with the inserted terminal holes, significantly reducing wiring time and making it suitable for batch testing. Depending on whether the test switch is a three-wire or four-wire product, multiple elastic ejector pins can simultaneously contact multiple connection terminals of the test switch (such as 3P / 4P terminals), enabling simultaneous power supply and signal acquisition. Furthermore, when the elastic ejector pins retract, they are completely physically separated from the test switch circuit, avoiding the short-circuit risk caused by forgetting to disconnect the power in traditional equipment, ensuring safe and reliable use.

[0035] It's important to understand that the infrared, acoustic-optical, and tactile delay test switches are available not only with two-wire products but also with three-wire and four-wire specifications. Multiple flexible pins connect to multiple test lines. Therefore, a selector switch 25 is provided on the control panel 2 to switch between different test lines. This switch 25 offers selectable positions for neutral, two-wire, three-wire, and four-wire modes, thus covering the testing requirements of two-wire (L / N), three-wire (L / N / GND), and four-wire (L / N / SIG / GND) product specifications. For example, when testing... When testing a three-wire tactile switch, rotating the switch 25 to the three-wire position automatically assigns the pin function. The switch position and the flexible pin layout are interdependent; when the three-wire position is selected, only three flexible pins are energized, preventing accidental short circuits caused by four-wire pins. This design allows the three-in-one switch testing fixture to support test switches with multiple wire counts without requiring equipment replacement or rewiring, saving time. By rotating the switch, operators can quickly select the correct test mode, improving compatibility, simplifying operation, reducing wiring errors, and facilitating expansion and maintenance.

[0036] The following is combined Figure 1-2 The testing method for tactile delay switches is explained in detail:

[0037] The load indicator light 8 and timer 9 are respectively installed on the control panel 2, and a power-on switch 26 is provided on the operation panel of the control panel 2. During the switch test, the tester can directly observe the working status of the load indicator light 8 and timer 9. The test box 1 is equipped with an openable cover. The test method for the tactile delay switch in this embodiment is as follows: The cover needs to be opened for testing. First, after turning on the power of the equipment, place the tactile delay switch on the positioning seat 3 and adjust the circuit switching switch 25 according to the product model.

Additionally, the light source generator 6 is an adjustable incandescent lamp installed at the top of the test chamber 1.

To detect and record the decibel and illumination values ​​when the sound and light sensor switch is triggered, the test component includes a... The test chamber 1 includes a noise meter 11 for detecting the volume of the sound source generator 5. The noise meter 11 has a noise counting display screen 13 on the operation panel. The test chamber 1 also includes a light meter 12 for detecting the illumination of the light source generator 6. The light meter 12 has an illumination counting display screen 14 on the operation panel. The light meter 12 is located next to the positioning base 3. The adjustable incandescent lamp is located directly above the positioning base 3 and the light meter 12, ensuring that the brightness of the incandescent lamp illuminating the product and the probe of the light meter 12 is consistent. The output brightness of the adjustable incandescent lamp is controlled by the dimming knob 24 on the operation panel. This method is suitable for measuring light-controlled switch products. The testing method for the sound and light sensor switch in this embodiment is as follows: First, place the sound and light sensor switch on the positioning base 3 and adjust the circuit switching switch 25 according to the model; Second, close the box cover, press the start button 21, and the spring pin pops out to make electrical contact with the sound and light sensor switch; Third, turn on the noise meter 11 and the light meter 12, press the sound source control button 22, and control the noise value according to the noise meter, and adjust the dimming knob 24, and control the light value of the incandescent lamp according to the light meter; Fourth, turn on the power switch 26 of the control panel 2 to supply power to the product. The load indicator light 8 will light up when the product is powered on (after lighting up, the sound and light will be turned off), and the timer will start timing.

The control component includes an infrared control button 23 on the operation panel for controlling the opening and closing of the quartz heating tube infrared generator. The working principle of this quartz heating tube infrared generator is to generate heat within the heating tube through current, and then convert the heat into infrared radiation. The testing method for the infrared sensor switch in this embodiment is as follows: First, after placing the infrared sensor switch on the positioning base 3, adjust the circuit switch 25 according to the model; second, close the chamber cover and press the start button 21, which pops out the contact infrared sensor switch through the elastic pin, preparing to power the product; third, press the infrared control button 23, and irradiate the product with infrared light through the infrared generator 7; fourth, toggle the power switch on the control panel 2 to power the product.
