[0028] Reference Figures 1 to 4The switch plug of the embodiment of the present invention includes a housing 100, a circuit board 200, a control block 300 and a conductive spring 600. One end of the housing 100 is a mounting surface 110, and the other end is open. An insertion hole 112 is provided on the side of the housing 100 close to the mounting surface 110; the circuit board 200 is fixedly connected to the inner side of the mounting surface 110, and the circuit board 200 is provided with a conductive contact 210; the control block 300 is inserted into the insertion hole 112, and the control block 300 is provided with a through hole 310. The control block 300 can slide in the insertion hole 112 so that the through hole 310 and the conductive contact 210 are in contact with each other. 10 corresponds, or is staggered; the conductive spring clip 600 is elastic, and the conductive spring clip 600 and the conductive contact 210 are correspondingly arranged, one end of the conductive spring clip 600 is fixed in the shell 100, and the other end abuts against the control block 300, or passes through the through hole 310 and abuts against the conductive contact 210; the conductive column 400 is inserted into the mounting surface 110 of the shell 100, and the conductive column 400 is electrically connected to the circuit board 200; wherein, the shell 100 has a built-in stop block 500, and the stop block 500 can be detachably connected to the end of the control block 300 so that the through hole 310 and the conductive contact 210 are correspondingly arranged.

[0029] In actual use, there are two usage states:

[0030] Usage state 1 - Insert the lamp into the plug. Before inserting the lamp into the housing 100, pull the control block 300 outward so that the through hole 310 of the control block 300 and the conductive contact 210 are offset. Then insert the lamp into the housing 100. After the lamp is inserted, the lamp and the conductive spring 600 abut against each other. Then, insert the control block 300 into the housing 100 so that the through hole 310 and the conductive contact 210 are aligned. At this point, the conductive spring 600, the lamp, and the conductive contact 210 are electrically connected and can be used normally by the user.

[0031] Usage state 2: Pull the plug out of the end of the lamp tube. Before pulling out the lamp tube, pull the control block 300 outward so that the through hole 310 of the control block 300 and the conductive contact 210 are offset, and then pull the lamp tube out of the housing 100;

[0032] It should be emphasized that during normal use of the lamp tube, the conductive spring 600 and the conductive contact 210 remain connected by the fixedly connected stop block 500 and the control block 300. Furthermore, the stop block 500 can constrain the position of the control block 300, ensure that the positions of the through hole 310 and the conductive contact 210 correspond, and ensure that the conductive spring 600 can pass through the through hole 310 and contact the conductive contact 210.

[0033] In summary, by extending or pulling out the control block 300, the conductive spring 600 and the conductive contact 210 on the circuit board 200 can be controlled to contact or separate, thereby avoiding electric shock during installation or removal.

[0034] It should be noted that a limiting slope 311 is provided on one side of the through hole 310 close to the insertion hole 112 . The limiting slope 311 is used to limit the position of the conductive spring 600 to prevent the conductive spring 600 from being separated from the conductive contact 210 .

[0035] In some embodiments, the free end of the conductive spring 600 is bent to form an abutment portion, which can pass through the through hole 310 and abut against the conductive contact 210. Specifically, the abutment portion with an inclined surface can cooperate with the limiting inclined surface 311 to limit the position of the entire conductive spring 600 and prevent the conductive spring 600 from separating from the conductive contact 210.

[0036] In order to reduce the volume of the housing 100 , a groove 111 is provided on one side of the housing 100 close to the mounting surface 110 , and an insertion hole 112 is provided in the groove 111 , so that the end of the control block 300 installed in the insertion hole 112 can be built into the groove 111 .

[0037] Furthermore, to facilitate pressing, a pressing portion 320 is provided at one end of the control block 300 protruding from the insertion hole 112, and the end surface of the pressing portion 320 is configured as an arc surface. In addition, to facilitate pulling out the control block 300, a gap is provided between the pressing portion 320 and the bottom surface of the groove 111 when the control block 300 and the stop block 500 are connected.

[0038] Preferably, the stop block 500 is provided with a slot 510, with triangular first snap points 511 provided on both sides of the slot 510. Second snap points 330 are provided on both sides of the end of the control block 300 that extends into the housing 100. The control block 300 can be inserted into the slot 510, and the first snap points 511 and the second snap points 330 are engaged. Specifically, during the process of the control block 300 extending, the control block 300 directly extends into the slot 510, and the first snap points 511 and the second snap points 330 are engaged. This prevents the control block 300 from easily falling out of the slot 510 without external force, thus preventing the control block 300 from sliding freely and causing the through hole 310 and the conductive contact 210 to be misaligned, thereby ensuring that the conductive contact 210 and the conductive spring 600 are in contact, so that the lamp tube is normally powered.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
