Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, and particularly relates to a dimming function testing device. Background Technique

[0002] The working principle of a dimmer is mainly to control and change the phase angle of a thyristor to control the conduction degree, thereby changing the input voltage and current of an electric light source to obtain different intensities of light output. This device can directly replace the existing wall switch and adopt a single-phase live wire input wiring method, enabling users to adjust the light brightness and color temperature through operation interfaces such as a control panel, knob, button, remote control, etc.

[0003] After the existing dimmer is assembled, it is usually necessary to detect the electrical signal. Workers often use an ammeter to connect and test the wiring terminal at the output end of the dimmer. Since the contact pens of the ammeter are in two groups, it is often necessary to hold them with both hands and conduct contact testing on the dimmer, which is inconvenient to operate. Therefore, a dimming function testing device is proposed. Content of the Utility Model

Connect the input end of the dimming component to the power supply, connect the output end of the dimming component through the probe 14 of the contact component, and then control the knob on the adjusting component to adjust. Detect the dimming component by changing the voltage value on the voltage display module 8. The voltage display module 8 is a publicly known existing structure and is well-known to those skilled in the art. The specific principle and connection method will not be described in detail. The distance of the contact component can be adjusted through the adjusting component to facilitate adaptation to different dimming components. A lateral contact point is also arranged on the side wall of the probe 14, which can make contact according to the wiring position of different models of dimming components. By rotating the adjusting column 3, the adjusting component and the contact component can be lifted, and the adjusting column 3 can be reset through the reset component.

[0025] Please refer to Figure 1 、 2 Figures 4 and 5, the above-mentioned adjusting assembly can be any one. An embodiment is provided in this application.
