[0014] The present application is further described below with reference to the accompanying drawings:

[0015] See attached Figure 1-9 A lamp tube that is easy to connect includes a lamp body 1 and a main end cover 2 that is detachably covered on a port at one end of the lamp body 1; a connector 4 for connecting an internal power line of the lamp body 1 with an external power line is provided in the main end cover 2; the main end cover 2 is provided with a receiving cavity 21 that communicates with the inside and outside of the lamp body 1, and the connector 4 is installed in the receiving cavity 21; the connector 4 and the receiving cavity 21 are detachably connected by a snap-fit ​​structure; the snap-fit ​​structure includes an elastic hook 22 provided in the receiving cavity 21 and a hanging portion provided on the connector 4 for the elastic hook 22 to hook.

[0016] In this technical solution, a connector 4 is provided inside the main end cover 2 to facilitate the connection of the internal power line with the external power line, and the connector 4 and the main end cover 2 are connected by a snap-fit ​​structure, which makes installation and disassembly simple and quick, and the connector 4 can be inserted into the receiving cavity 21 and fixed after wiring, providing sufficient space for convenient wiring operations.

[0017] The connector 4 can be any existing connector 4 that can connect two power lines together and form an electrical connection. In this embodiment, the connector 4 is a press-type connector 4, and the connector 4 includes a first jack 42 for inserting the internal power line and a second jack 43 for inserting the external power line.

[0018] One end of the receiving cavity 21 is provided with an installation opening 211 for inserting the connector 4, and the other end of the receiving cavity 21 is provided with a communication opening 212 that communicates with the interior of the lamp body 1, allowing the internal power cord to enter the receiving cavity 21 and connect to the connector 4. The elastic hook 22 includes an elastic arm 221 provided on the wall of the receiving cavity 21 and a snap-on protrusion 222 on the elastic arm 221; the receiving portion is a groove 41 on the side wall of the connector 4; the snap-on protrusion 222 is hooked into the groove 41.

[0019] The buckle structure includes two groups, and the elastic hooks 22 of the two groups of buckle structures are arranged axially symmetrically; the supporting parts of the two groups of buckle structures are respectively arranged on both sides of the connector 4.

[0020] During installation, the connector 4 is inserted into the receiving cavity 21, and contacts the snap protrusion 222, causing the elastic arm 221 to elastically expand outward until the groove 41 reaches the position of the snap protrusion 222. The snap protrusion 222 falls into the groove 41, and the elastic arm 221 is reset, that is, the connector 4 is held between the two elastic hooks 22.

[0021] The lamp tube for easy wiring also includes a secondary end cap 3 and a DIP switch 5 for adjusting the color temperature and / or brightness of the lamp body 1. The DIP switch 5 is mounted in a receiving cavity 21. The secondary end cap 3 is detachably mounted on the main end cap 2 and covers the receiving cavity 21. The secondary end cap 3 is provided with a wire hole 31 for passing an external power cord.

[0022] The lever of the conventional lamp's DIP switch 5 is exposed on the lamp cover, which is easy to be accidentally touched and has poor waterproof and dustproof effects.

[0023] This technical solution hides the dial switch 5 inside the main end cover 2. The dial switch 5 can be exposed by opening the auxiliary end cover 3 for adjustment, which can prevent accidental touch and has waterproof and dustproof effects.

[0024] The main end cover 2 is provided with a connecting portion 23, on which the receiving chamber 21 is located. The secondary end cover 3 is rotatably mounted on the connecting portion 23 about a predetermined axis L to switch between an open position and a locked position. The secondary end cover 3 is provided with a sleeve portion 32 for covering the connecting portion 23, and the inner wall of the sleeve portion 32 is provided with a limiting protrusion 33. The outer wall of the connecting portion 23 is provided with a connecting groove 24 extending about the predetermined axis L. The sleeve portion 32 is sleeved on the connecting portion 23, and the limiting protrusion 33 falls into the connecting groove 24, allowing the secondary end cover 3 to rotate along the extending direction of the connecting groove 24. The outer wall of the connecting portion 23 is also provided with an inlet and outlet 241 that communicates with the connecting groove 24 and allows the limiting protrusion 33 to enter and exit the connecting groove 24. The limiting protrusion 33 is opposite the inlet and outlet 241 when the secondary end cover 3 is in the open position. The limiting protrusion 33 is offset from the inlet and outlet 241 when the secondary end cover 3 is in the locked position.

[0025] During installation, align the limiting protrusion 33 with the entrance and exit 241 and insert it into the connecting groove 24, rotate the auxiliary end cover 3 so that the limiting protrusion 33 and the entrance and exit 241 are offset, and the auxiliary end cover 3 can be locked; when opening, rotate the auxiliary end cover 3 so that the limiting protrusion 33 is opposite to the entrance and exit 241 so that the limiting protrusion 33 can be moved out of the entrance and exit 241 and the auxiliary end cover 3 can be removed.

[0026] The auxiliary end cover 3 of the present technical solution is locked or opened by rotating, and the assembly and disassembly operation is simple and quick.

[0027] The lamp body 1 includes a tubular shell 11 and an LED light source (not shown in the drawings) installed in the shell 11 ; a slot 25 is provided on the inner side of the main end cover 2 , and the edge of the shell 11 is inserted into the slot 25 .

[0028] During installation, the end of the lamp body 1 is inserted into the main end cover 2 until the edge of the housing 11 falls into the slot 25 .

[0029] The main end cover 2 of the present technical solution is connected to the lamp body 1 by plugging, and is easy to assemble and disassemble.

[0030] The housing 11 is provided with a light source cavity 12 for receiving an LED light source, and the light source cavity 12 is communicated with the receiving cavity 21. The LED light source is a light bar or a light belt; the light source cavity 12 is provided with a mounting slot 13 for inserting the LED light source.
