[0038] Referring to Figures 1 to 8 The splicing device 20 is used to realize the combined connection between the lamp tube units 70 of the long lamp tube. The splicing device 20 comprises a male butt joint 30, a male side conductive assembly, a female butt joint 50 and a female side conductive assembly. The male side conductive assembly comprises a first conductive piece 41 connected to the male butt joint 30 and a second conductive piece 42 connected to the male butt joint 30. The female butt joint 50 is detachably connected to the male butt joint 30. The female side conductive assembly comprises a third conductive piece 61 connected to the female butt joint 50 and a fourth conductive piece 62 connected to the female butt joint 50. The third conductive piece 61 is used to butt joint with the first conductive piece 41, and the fourth conductive piece 62 is used to butt joint with the second conductive piece 42 to transmit current. One of the third conductive piece 61 and the first conductive piece 41 is provided with elasticity, and one of the fourth conductive piece 62 and the second conductive piece 42 is provided with elasticity.

[0039] By connecting the male butt joint 30 and the female butt joint 50 to different lamp tube units 70 respectively, the relative fixation between the two adjacent butt joint lamp tube units 70 can be realized after the combined connection of the male butt joint 30 and the female butt joint 50. At the same time when the male butt joint 30 and the female butt joint 50 are assembled, the third conductive piece 61 and the first conductive piece 41 are in contact with each other, and the fourth conductive piece 62 and the second conductive piece 42 are in contact with each other to transmit electric energy or signals between the two adjacent lamp tube units 70. During butt joint, through the elastic contraction of one side of the third conductive piece 61 and the first conductive piece 41 and the elastic contraction of one side of the fourth conductive piece 62 and the second conductive piece 42, good abutting contact can be maintained and good electrical conduction effect can be maintained when there is vibration in the installation site or the long lamp tube is bent, so that the lamp tube can be normally illuminated.

[0040] Referring to Figures 3 to 7In one embodiment, the male connector 30 comprises a first tubular base 31 and a convex base 32 connected to the first tubular base 31; the convex base 32 is provided with a concave hole 321 at the end away from the first tubular base 31; the first conductive member 41 is arranged at the end of the convex base 32 away from the first tubular base 31 or outside the convex base 32; the second conductive member 42 is arranged at the bottom of the concave hole 321; the female connector 50 comprises a second tubular base 51 and a middle shaft 52 in the second tubular base 51; the middle shaft 52 is used to pass through the concave hole 321; the fourth conductive member 62 is arranged at the end of the middle shaft 52; the third conductive member 61 is between the second tubular base 51 and the middle shaft 52 and away from the end of the middle shaft 52 in the axial direction.

[0041] Since the first conductive member 41 is exposed to the convex base 32 and the second conductive member 42 is arranged at the bottom of the concave hole 321, the first conductive member 41 and the second conductive member 42 can avoid contacting the same metal part and short-circuiting.

[0042] Please refer to Figure 5 and Figure 6 In one embodiment, the first conductive member 41 is fixed at the end of the convex base 32 away from the first tubular base 31; the second conductive member 42 is elastic and the movable range is limited in the concave hole 321; the third conductive member 61 is elastic; and the fourth conductive member 62 is fixed at the end of the middle shaft 52 towards the outside of the second tubular base 51.

[0043] The second conductive member 42 keeps electrical contact with the first conductive member 41 through elastic deformation; since the elastic second conductive member 42 is limited in the concave hole 321, the second conductive member 42 will not be exposed to the outside of the convex base 32 in the process of shape change, which can avoid the second conductive member 42 from being irreversibly deformed due to being excessively compressed by external parts or being hooked by external parts. Similarly, the third conductive member 61 keeps electrical contact with the fourth conductive member 62 through elastic deformation; since the elastic third conductive member 61 is between the second tubular base 51 and the middle shaft 52 and away from the end of the middle shaft 52, the middle shaft 52 has a blocking effect on external parts, which can avoid the third conductive member 61 from being irreversibly deformed due to being excessively compressed by external parts or being hooked by external parts.

[0044] Please refer to Figure 5 and Figure 6In one embodiment, the second conductive member 42 is a spiral structure with elasticity, one end of the second conductive member 42 is fixedly connected with the bottom of the recess 321; the third conductive member 61 is a spiral structure with elasticity, one end of the third conductive member 61 is connected with the second tube base 51. By adopting the spiral structure of the second conductive member 42 and the third conductive member 61, the second conductive member 42 or the third conductive member 61 can have a larger elastic space in a certain axial length, so that the stable electrical connection between the first conductive member 41 and the second conductive member 42, or the third conductive member 61 and the fourth conductive member 62 can be maintained when there is a severe vibration in the installation environment or the long lamp tube has a significant bending, and the stability of the lamp tube lighting is ensured.

[0045] Referring to Figure 3 , specifically, the first conductive member 41, the second conductive member 42, the third conductive member 61 or the fourth conductive member 62 is made of metal or alloy. The first conductive member 41 is annular, and can ensure the contact and abutment between the first conductive member 41 and the second conductive member 42 when the male connector 30 and the female connector 50 are at different matching angles. The first conductive member 41 is fixed on the end of the convex base 32 away from the first tube base 31 by a screw. The fourth conductive member 62 is in the form of a sheet and is fixedly covered on the end of the central shaft 52.

[0046] Referring to Figure 7 , the second tube base 51 is provided with a cylindrical groove 511 for accommodating and further protecting the third conductive member 61.

[0047] Referring to Figure 3 and Figure 6 , in one embodiment, the outer side of the convex base 32 is uniformly distributed with a plurality of buckling blocks 322 along the circumference; the inner side of the second tube base 51 is formed with a buckling groove 512 in the form of L, one part of the buckling groove 512 extends along the axial direction of the second tube base 51, and the other part extends along the circumferential direction of the second tube base 51; one opening of the buckling groove 512 faces the outside of the second tube base 51; the buckling groove 512 is used for accommodating the buckling block 322, so that the male connector 30 and the female connector 50 are relatively fixed in the axial direction.

[0048] After the second tube base 51 is axially aligned with the first tube base 31, the first tube base 31 is moved axially towards the second tube base 51, the buckling block 322 enters the buckling slot 512 from the opening of the buckling slot 512, and after being moved to the intersection of the axial extension and the circumferential extension of the buckling slot 512, the buckling block 322 is accommodated into the circumferential extension of the buckling slot 512 through the relative rotation between the first tube base 31 and the second tube base 51 in the circumferential direction, so that the axial movement of the buckling block 322 relative to the female connector 50 is blocked, thereby the combination and splicing between the male connector 30 and the female connector 50 can be simply and quickly completed; after the edges of the first tube base 31 and the second tube base 51 abut against each other, the cooperation between the buckling blocks 322 and the buckling slots 512 which are uniformly distributed in the circumferential direction can avoid the bending of the splicing part due to the action of gravity, and further ensure the electrical contact stability between the male-side conductive assembly and the female-side conductive assembly.

[0049] In the embodiment, in order to simplify the mechanism of the male connector 30 and reduce the processing difficulty, the buckling block 322 is three, and is integrally formed with the convex base 32.

[0050] Please refer to Figure 6 and Figure 7 In one embodiment, the inner side of the second tube base 51 is provided with an axial plate 513 and a circumferential plate 514; the axial extension of the buckling slot 512 is formed between the axial plate 513 and the circumferential plate 514; the axial plate 513 also plays a limiting role in the circumferential rotation of the buckling block 322; the circumferential extension of the buckling slot 512 is located on the inner side of the circumferential plate 514; the buckling block 322 and one of the circumferential plates 514 are provided with a clamping pellet 323, and the other is provided with a groove for accommodating the clamping pellet 323.

[0051] The axial plate 513 and the circumferential plate 514 play a role in forming the buckling slot 512, and after the buckling block 322 is rotated to the right position relative to the female connector 50, the clamping pellet 323 is accommodated into the groove in an interference fit, so as to lock the angle of the buckling block 322 relative to the female connector 50, and avoid the automatic disconnection between the male connector 30 and the female connector 50.

[0052] Please refer to Figure 6 In the embodiment, the axial plate 513, the circumferential plate 514 and the second tube base 51 are integrally formed. Specifically, the clamping pellet 323 is arranged on the side of the buckling block 322 close to the first tube base 31, and the groove is arranged on the side of the circumferential plate 514 facing the circumferential extension of the buckling slot 512.
