[0034] In order to better understand the lamp tube for lighting of the present application, the lamp tube for lighting of the present application is further explained as follows:

[0035] The lamp tube for lighting 10 of an embodiment comprises a lamp shell 100, a lamp plate 200, a power board 300, two connecting assemblies 400 and two plugs 500. The PIN needle 600 is arranged on each plug 500, and the two plugs 500 are sealed at the two ends of the lamp shell 100 to form a light emitting cavity 101. The lamp plate 200 and the power board 300 are arranged in the light emitting cavity 101 and connected with the lamp shell 100, and the lamp plate 200 and the power board 300 are electrically connected. The two connecting assemblies 400 are arranged one by one corresponding to the two plugs 500. The end of the PIN needle 600 located in the light emitting cavity 101 is provided with a sliding slot 601, and the hole wall of the sliding slot 601 is provided with a clamping slot 602. Each connecting assembly 400 comprises a connecting wire 410, a plug-in terminal 420 and a clamping terminal 430 connected to the two ends of the connecting wire 410, respectively. The lamp plate 200 and the power board 300 are electrically connected to the PIN needle 600 of the corresponding plug 500 through the plug-in terminal 420 of the corresponding connecting assembly 400. The clamping terminal 430 of each connecting assembly 400 is plugged into the sliding slot 601 of the PIN needle 600 of the corresponding plug 500 and is clamped into the clamping slot 602.

[0036] The lamp tube 10 for lighting described above is provided with a sliding slot 601 at the end of the PIN needle 600 located in the light emitting cavity 101, and a clamping slot 602 is formed on the hole wall of the sliding slot 601. The plug-in terminal 420 and the clamping terminal 430 are respectively connected to the two ends of the connecting wire 410. The clamping terminal 430 is plugged into the sliding slot 601 of the PIN needle 600 of the corresponding plug 500 and clamped into the clamping slot 602. That is, the clamping terminal 430 is plugged into the sliding slot 601 to realize the electrical connection between the connecting assembly 400 and the PIN needle 600. When the clamping terminal 430 is plugged into the sliding slot 601, it is further clamped into the clamping slot 602, so that the PIN needle 600 has a clamping effect on the clamping terminal 430, effectively improving the connection reliability of the PIN needle 600 and the connecting assembly 400. The plug-in terminal 420 of the connecting assembly 400 is electrically connected to the power panel 300 and the sliding slot 601 of the PIN needle 600, which realizes the assembly of the power panel 300 and the PIN needle 600. In the case of ensuring the reliability of the electrical connection, the assembly efficiency of the lighting lamp is effectively improved, and the assembly operation difficulty of the lighting lamp is reduced.

[0037] In one embodiment, the clamping terminal 430 of each connecting assembly 400 includes a clamping body 431 and a resilient member 432. The clamping body 431 is provided with a limiting hole 401 and a protruding hole 402 coaxially arranged. The protruding hole 402 is located at the end of the limiting hole 401, and the protruding hole 402 communicates with the limiting hole 401. The resilient member 432 is clamped on the limiting hole 401, and at least part of the resilient member 432 protrudes from the protruding hole 402. The resilient member 432 is slidably connected to the clamping body 431 at the limiting hole 401 and the protruding hole 402. The clamping body 431 is plugged into the sliding slot 601 of the PIN needle 600 of the corresponding plug 500. When the clamping body 431 is plugged into the sliding slot 601 of the PIN needle 600 of the corresponding plug 500, the resilient member 432 protruding from the protruding hole 402 is clamped into the clamping slot 602. It can be understood that the connecting assembly 400 is clamped on the clamping body 431 in the form of the resilient member 432 and is telescopic. The resilient member 432 can be smoothly retracted into the sliding slot 601 of the clamping body 431 at the limiting hole 401 and the protruding hole 402, and can be smoothly expanded to make the resilient member 432 clamped into the clamping slot 602 when the resilient member 432 slides into the clamping slot 602. The clamping stability of the resilient member 432 in the clamping slot 602 is effectively ensured, and the resilient member 432 is further slid into the clamping slot 602.

[0038] In one of the embodiments, the number of the clamping grooves 602 is two. Further, the number of the protruding holes 402 is two, the two protruding holes 402 are arranged one by one corresponding to the clamping grooves 602, the two protruding holes 402 are respectively located at two ends of the limiting hole 401, and the two protruding holes 402 are in communication with the limiting hole 401, the elastic members 432 are at least partially protruded from the two protruding holes 402 respectively, and the elastic members 432 are slidably connected to the clamping body 431 at the limiting hole 401 and the two protruding holes 402, the elastic member 432 protruding from each protruding hole 402 is clamped in the corresponding clamping groove 602 when the clamping body 431 is inserted into the sliding groove 601 of the PIN needle 600 of the corresponding plug 500, which effectively ensures the smoothness and independence of the extension and deepening of each elastic member 432 at the corresponding protruding hole 402, and is beneficial to simplify the assembly process of the elastic member 432 and improve the assembly efficiency of the lighting lamp tube 10.

[0039] In one of the embodiments, the elastic member 432 includes an elastic part 4321 and two clamping parts 4322, the two clamping parts 4322 are arranged one by one corresponding to the two protruding holes 402, the elastic part 4321 is arranged at the limiting hole 401, the two clamping parts 4322 are respectively located at two ends of the elastic part 4321, each clamping part 4322 is clamped at the limiting hole 401, and each clamping part 4322 is at least partially located at the protruding hole 402 and at least partially protrudes from the protruding hole 402, the elastic part 4321 and the two clamping parts 4322 are slidably connected to the clamping body 431 at the limiting hole 401 and the two protruding holes 402, each clamping part 4322 protruding from the corresponding protruding hole 402 is clamped in the corresponding clamping groove 602 when the clamping body 431 is inserted into the sliding groove 601 of the PIN needle 600 of the corresponding plug 500, which is beneficial to the stable arrangement of the elastic part 4321 on the limiting hole 401, and is beneficial to the smooth and effective expansion and contraction of the elastic part 4321 when the clamping part 4322 extrudes the elastic part 4321.

[0040] In one of the embodiments, the two ends of the elastic part 4321 respectively abut against the two clamping parts 4322, which is beneficial to the effective and smooth expansion and contraction of the elastic part 4322.

[0041] In one of the embodiments, the elastic part 4321 is elastic silica gel or spring, which ensures the contraction and expansion effect of the elastic part 4321.

[0042] In one of the embodiments, the clamping part 4322 is a block, which is used to block the limiting hole 401 at the two ends of the elastic part 4321, so as to ensure that the elastic part 4321 can smoothly and effectively expand and contract when the clamping part 4322 extrudes the elastic part 4321, thereby ensuring that the clamping part 4322 can smoothly and effectively extend into the protruding hole 402 and protrude out of the protruding hole 402.

[0043] In one embodiment, the clamping groove is a cylindrical groove, a columnar hole, an arc-shaped open groove or an arc-shaped port hole. It can be understood that if the clamping groove is an annular groove around the wall of the sliding groove, the clamping part can be further slid into the clamping groove more smoothly by abutting the inner wall of the sliding groove with the clamping body at any position of the wall of the sliding groove. However, since the PIN pin is more directly used with a conventional PIN pin of the same specification, the volume of the conventional PIN pin is actually smaller, that is, the conventional PIN pin is actually formed with a sliding groove, but the thickness of the groove wall of the sliding groove is smaller. Further, if the lamp tube plug needs to be prepared without additional mold opening, in order to increase the clamping stability of the clamping part, the clamping groove needs to have a certain depth, and if the clamping groove is provided on the circumferential wall of the sliding groove of the clamping body, the cross-sectional area of the clamping body needs to be increased, that is, the volume of the clamping body needs to be increased. However, actually increasing the volume of the clamping body will increase the assembly cost of the lighting lamp tube because a new mold needs to be opened for the preparation of the plug. Therefore, the clamping groove is a cylindrical groove, a columnar hole, an arc-shaped open groove or an arc-shaped port hole. The arc-shaped open groove is a groove structure with an arc-shaped slot, and the arc-shaped port hole is a hole structure with an arc-shaped opening. Thus, the circumferential wall of the sliding groove is used for structural support to ensure the structural strength and stability of the clamping body.

[0044] It can be understood that if the clamping groove is a cylindrical groove or an arc-shaped open groove, since the thickness of the PIN pin is small, even if the sliding groove wall of the PIN pin is used to the maximum extent, it is still difficult to ensure the connection stability of the PIN pin and the clamping terminal during the assembly of the lighting lamp tube, that is, it is difficult to effectively improve the connection strength of the PIN pin and the clamping terminal. Therefore, in one embodiment, the bottom of each clamping groove 602 is provided with a magnetic attraction piece 800. When each clamping part 4322 protruding from the corresponding protruding hole 402 is clamped in the corresponding clamping groove 602, the magnetic attraction piece 800 is magnetically connected with the clamping part 4322. By effectively increasing the magnetic attraction piece 800, the connection strength of the PIN pin 600 and the clamping terminal 430 is improved, and the connection stability of the PIN pin 600 and the clamping terminal 430 is further improved.

[0045] It can be understood that if the clamping groove is a cylindrical groove, a columnar hole, an arc-shaped open slot or an arc-shaped port hole, that is, the clamping groove is not a ring-shaped groove surrounding the peripheral wall of the sliding groove, when the clamping terminal is clamped to the PIN pin, if the clamping part is in contact with the inner wall of the sliding groove along the peripheral wall of the sliding groove after the clamping body is inserted too deeply beyond the clamping hole, and the clamping part cannot be further clamped in the clamping groove smoothly, so that the illuminating lamp tube needs to be inserted and pulled out by the operator during assembly, and the clamping part is in the state of being clamped in the clamping groove, which not only reduces the assembly efficiency of the illuminating lamp tube, but also causes the clamping part not to be clamped in the clamping groove during the assembly process of the illuminating lamp tube, and further increases the rework burden of the illuminating lamp tube, further affecting the assembly efficiency of the illuminating lamp tube, therefore, in one embodiment, two advancing holes 603 are further provided on the groove wall of the sliding groove 601, the extending direction of each advancing hole 603 is the same as the extending direction of the sliding groove 601, one end of the two advancing holes 603 is located at the opening of the sliding groove 601, and the other end of the two advancing holes 603 is located at the clamping groove 602, two clamping parts 4322 are correspondingly arranged with the two advancing holes 603, and each clamping part 4322 slides into the clamping groove 602 along the advancing hole 603 when the clamping body 431 is inserted into the sliding groove 601 of the PIN pin 600 of the corresponding plug 500. Further, in the direction from the end of the advancing hole 603 close to the clamping groove 602 to the end away from the clamping groove 602, the width of each advancing hole 603 in the thickness direction of the groove wall of the sliding groove 601 gradually increases, the width of the end of each advancing hole 603 away from the clamping groove 602 in the thickness direction of the groove wall of the sliding groove 601 is greater than or equal to the length of the clamping part 4322 protruding from the protruding hole 402, and the width of the end of each advancing hole 603 close to the clamping groove 602 in the thickness direction of the groove wall of the sliding groove 601 is less than the length of the clamping part 4322 protruding from the protruding hole 402.It can be understood that the width of each advancing hole 603 in the thickness direction of the slot wall of the sliding slot 601 gradually increases in the direction from the end of the advancing hole 603 close to the clamping slot 602 to the end of the advancing hole 603 away from the clamping slot 602, that is, the width of the cross section of the advancing hole 603 in the thickness direction of the slot wall of the sliding slot 601 gradually increases in the direction from the end of the advancing hole 603 close to the clamping slot 602 to the end of the advancing hole 603 away from the clamping slot 602, so that the contraction force of the two clamping portions 4322 on the elastic portion 4321 gradually increases when the clamping portion 4322 slides into the clamping slot 602 along the advancing hole 603, the width of the end of each advancing hole 603 away from the clamping slot 602 in the thickness direction of the slot wall of the sliding slot 601 is greater than or equal to the length of the clamping portion 4322 protruding from the protruding hole 402, and the width of the end of each advancing hole 603 close to the clamping slot 602 in the thickness direction of the slot wall of the sliding slot 601 is less than the length of the clamping portion 4322 protruding from the protruding hole 402, that is, the clamping portion 4322 will not be extruded by the advancing hole 603 when the clamping portion 4322 enters the advancing hole 603, and the clamping portion 4322 will be extruded by the advancing hole 603 during the process of gradually sliding into the advancing hole 603, thereby facilitating the smooth sliding of the clamping portion 4322 into the clamping slot 602, reducing the need for the operator to extrude the clamping portion 4322 in advance to force the clamping portion 4322 into the sliding slot 601 when the clamping portion 4322 enters the sliding slot, simplifying the assembly process of the lighting lamp tube 10, and effectively ensuring the effective clamping of the clamping portion 4322 in the clamping slot 602, thereby effectively improving the assembly efficiency of the lighting lamp tube 10.

[0046] In one embodiment, the circumferential wall of the clamping body 431 away from the end of the connecting line 410 is provided with a clearance gap 403 between the slot wall of the sliding slot 601 when the clamping body 431 is inserted into the sliding slot 601, which facilitates the smooth insertion of the clamping body 431 into the sliding slot 601.

[0047] In one embodiment, the PIN pin 600 and the plug 500 are integrally formed, which improves the setting stability of the PIN pin 600 on the plug 500.

[0048] In one embodiment, the lamp housing 100 is provided with a clamping protrusion 700, the clamping protrusion 700 and the lamp housing 100 form a clamping port 102, the lamp plate 200 and / or the power plate 300 are clamped at the clamping port 102, and the lamp plate 200 and / or the power plate 300 are connected with the lamp housing 100 and the clamping protrusion 700 respectively, which improves the setting stability of the lamp plate 200 or the power plate 300 in the lamp housing 100.

[0049] In one of the embodiments, the clamping protrusion 700 is integrally formed with the lamp shell 100, which improves the connection stability and compactness of the clamping protrusion 700 and the lamp shell 100, and further improves the clamping stability of the lamp panel 200 or the power panel 300 and the structural compactness of the lighting lamp tube 10.
