At the same time, the terminal wire 32 forms a stable connection with the pins 22, improving the connection stability and thus ensuring the product quality.

[0023] The beneficial effects of the embodiment of the present utility model are as follows:

[0024] The straight tube lamp in the embodiment of the present utility model is provided with a light source power supply component 1 and a lamp head component 2 connected to the light source power supply component 1. A connection component 3 is provided between the light source power supply component 1 and the lamp head component 2. The connection component 3 includes an input connection board 31 and a terminal wire 32 provided on the input connection board 31. One end of the terminal wire 32 is electrically connected to the light source power supply component 1. The terminal wire 32 is fixed on the input connection board 31. When installing the lamp head component 2, the input connection board 31 is directly inserted into the lamp head housing 21 of the lamp head component 2, and the terminal wire 32 can be automatically inserted into the pins 22 to form an electrical connection. Since trial insertion is not required and after the input connection board 31 is inserted into the lamp head housing 21, the terminal wire 32 can be automatically inserted into the pins 22, the straight tube lamp of the present utility model can reduce the installation time and improve the installation efficiency during installation. At the same time, the terminal wire 32 can be fixed on the input connection board 31, and the input connection board 31 can be fixed in the lamp head housing 21, so that the terminal wire 32 forms a stable connection with the pins 22, improving the connection stability and thus ensuring the product quality.

[0025] Specifically, in order to smoothly insert the terminal wire 32 into the pin 22, a pin through-hole 215 is provided in the pin 22. In the first embodiment of the present invention, the positions of the pin 22 and the terminal wire 32 correspond to each other. After the input connection board 31 is inserted into the lamp head housing 21, the terminal wire 32 can be inserted into the pin through-hole 215 of the pin 22. The pin through-hole 215 provides a space for mechanical fixation and electrical connection of the terminal wire 32. The terminal wire 32 can achieve electrical connection in the pin through-hole 215 and can be stably fixed in the pin through-hole 215 to achieve a firm mechanical connection. Compared with the traditional method of directly inserting an electronic wire into the pin 22, the stability of the terminal wire 32 can be ensured, thereby avoiding the occurrence of loose connection or poor contact, and improving the product quality of the straight tube lamp.

[0026] The straight tube lamp further includes a lamp tube 4. The lamp head assembly 2 is provided at both ends of the lamp tube 4, and the light source assembly 1 is provided inside the lamp tube 4. A receiving groove 211 is provided at one end of the lamp head housing 21 close to the lamp tube 4. The receiving groove 211 can accommodate the input connection board 31. The input connection board 31 can be inserted into the receiving groove 211. After insertion, the plane of the input connection board 31 is perpendicular to the central axis of the lamp head housing 21.

[0027] After the input connection board 31 is inserted into the lamp cap housing 21, the terminal wire 32 can correspond to the pin 22 in position and can be automatically inserted into the pin 22. On the inner side wall of the accommodation groove 211, guiding ribs 212 are provided. The guiding ribs 212 protrude from the inner side wall of the accommodation groove 211 towards the inside of the accommodation groove 211. The number of the guiding ribs 212 is one or more. The length direction of the guiding ribs 212 is parallel to the central axis direction of the lamp cap housing 21, that is, parallel to the insertion direction of the input connection board 31. At the edge of the input connection board 31, a guiding notch 311 is provided. The position of the guiding notch 311 corresponds to the number and position of the guiding ribs 212. The guiding notch 311 cooperates with the guiding ribs 212. When the input connection board 31 is inserted into the lamp cap housing 21, the guiding notch 311 can slide along the guiding ribs 212. By providing the guiding ribs 212 and the guiding notch 311, on the one hand, it can guide the installation direction of the input connection board 31 to ensure that the input connection board 31 can be vertically inserted into the accommodation groove 211. On the other hand, by using the positions of the guiding ribs 212 and the guiding notch 311, it can play a role in preventing misinstallation and misassembly, and can guide the installation equipment or installers to find the correct installation direction, so as to ensure that the terminal wire 32 after being installed can automatically align with the position of the pin 22, thus forming an automatic plug-in connection. In addition, the guiding ribs 212 can ensure that after the input connection board 31 is inserted, it will not rotate or shift in the accommodation groove 211, forming a radial limit for the input connection board 31 and ensuring a stable connection between the terminal wire 32 and the pin 22.

[0028] Further, at one end of the lamp cap housing 21 away from the lamp tube 4, a connection groove 213 is provided. The pin 22 is arranged on the connection groove 213. A clamping step 214 is formed between the connection groove 213 and the accommodation groove 211. After the input connection board 31 is inserted into the lamp cap housing 21, the input connection board 31 can abut against the clamping step 214. The clamping step 214 can axially fix the input connection board 31. Cooperating with the guiding ribs 212 and the guiding notch 311, it can axially and radially fix the input connection board 31, thereby further improving the connection stability.

[0029] See Figure 2, in the second embodiment, a DIP switch 312 is provided on the input connection board 31.

The light power supply integrated board 11 means that the light source component and the circuit board are of an integral structure, and the circuit board can directly supply power to the light source component. In the third embodiment, a light source pad 111 is provided on the light power supply integrated board 11. The connection pad 313 is electrically connected to the light source pad 111 through an electronic wire. One end of the electronic wire is welded to the connection pad 313, and the other end of the electronic wire is welded to the light source pad 111, so that the input connection board 31 is electrically connected to the light power supply component 1. When using a flexible substrate to fix the light source component, the length of the light power supply integrated board 11 is greater than the length of the lamp tube 4, so that the end of the light power supply integrated board 11 protrudes from the end of the lamp tube 4, thus facilitating the welding between the light source pad 111 and the electronic wire.

[0032] See Figure 4 , in the fourth embodiment, the light power supply component 1 includes a light source board and a power supply board 13. The light source component and the circuit board are separately arranged, and the light source component is arranged on the light source board. In the fourth embodiment, a jack 131 is provided on the power supply board 13. The edge of the input connection board 31 can be inserted into the jack 131, so that the input connection board 31 can form an integral body with the power supply board 13, and then the whole is assembled with the lamp head housing 21. A light source pad 111 is provided on the power supply board 13.
