Referring to fig. 1 to 8, a splicing apparatus 20 according to an embodiment of the present invention is used for realizing the combined connection between the lamp units 70 of the long lamp. The splicing device 20 includes: a male abutment 30, a male side conductive component, a female abutment 50 and a female side conductive component; the male side conductive assembly includes a first conductive member 41 connected to the male docking head 30 and a second conductive member 42 connected to the male docking head 30; the female docking head 50 is detachably connected to the male docking head 30; the female side conductive assembly includes a third conductive member 61 connected to the female docking head 50 and a fourth conductive member 62 connected to the female docking head 50; a third conductive member 61 for interfacing with the first conductive member 41, and a fourth conductive member 62 for interfacing with the second conductive member 42 to transmit current; one of the third conductive member 61 and the first conductive member 41 has elasticity; one of the fourth conductive member 62 and the second conductive member 42 has elasticity.

The male butt joint 30 and the female butt joint 50 are respectively connected to different lamp monomers 70, and after the male butt joint 30 and the female butt joint 50 are combined and connected, the two adjacent lamp monomers 70 can be relatively fixed. While the male and

female connectors

30 and 50 are assembled, the third conductive member 61 and the first conductive member 41 are in contact, and the fourth conductive member 62 and the second conductive member 42 are in contact, so as to transmit power or signals between two adjacent lamp cells 70. When in butt joint, the elastic contraction of one side of the third conductive member 61 and the first conductive member 41 and the elastic contraction of one side of the fourth conductive member 62 and the second conductive member 42 can keep good abutting contact when vibration exists in an installation place or a long lamp tube is bent, maintain good electric conduction effect and ensure that the lamp tube can normally illuminate

Referring to fig. 3 to 7, in one embodiment, the male joint 30 includes a first socket 31 and a boss 32 connected to the first socket 31; a concave hole 321 is formed at one end of the convex seat 32 far away from the first tube seat 31; the first conductive member 41 is disposed near one end of the boss 32 away from the first stem 31 or outside the boss 32; the second conductive member 42 is disposed near the bottom of the recess 321; the female butt joint 50 includes a second socket 51 and a central shaft 52 in the second socket 51; the middle shaft 52 is used for penetrating through a concave hole 321; fourth conductive member 62 is disposed proximate an end of central shaft 52; the third conductive member 61 is located between the second socket 51 and the central shaft 52 and is axially away from the end of the central shaft 52.

Since the first conductive element 41 exposes the boss 32 and the second conductive element 42 is disposed at the bottom of the recess 321, the first conductive element 41 and the second conductive element 42 are prevented from contacting the same metal component, and the first conductive element 41 and the second conductive element 42 are prevented from being shorted. Because the fourth conductive member 62 is disposed near the end of the middle shaft 52, the third conductive member 61 is disposed between the second socket 51 and the middle shaft 52 and axially away from the end of the middle shaft 52, so that the third conductive member 61 and the fourth conductive member 62 can be prevented from contacting the same metal component, and the third conductive member 61 and the fourth conductive member 62 can be prevented from short-circuiting.

Referring to fig. 5 and fig. 6, in one embodiment, the first conductive member 41 is fixed on an end of the boss 32 away from the first stem 31; the second conductive member 42 has elasticity, and the movable range is limited in the concave hole 321; the third conductive member 61 has elasticity; fourth conductive member 62 is fixed to an end of center shaft 52 facing the outside of second socket 51.

The second conductive member 42 is in electrical contact with the first conductive member 41 through elastic deformation, and the second conductive member 42 with elasticity is limited in the concave hole 321, so that the second conductive member 42 does not expose out of the boss 32 in the process of shape change, and the unrecoverable deformation of the second conductive member 42 caused by over-compression by an external component or hooking by the external component can be avoided. Similarly, the third conductive member 61 is in electrical contact with the fourth conductive member 62 through elastic deformation, and since the elastic third conductive member 61 is located between the second socket 51 and the middle shaft 52 and is far away from the outer end of the middle shaft 52, the middle shaft 52 has a blocking effect on the external component, so that the third conductive member 61 can be prevented from being deformed irreversibly due to over compression by the external component or hooking by the external component.

Referring to fig. 5 and fig. 6, in one embodiment, the second conductive member 42 is an elastic spiral structure, and one end of the second conductive member 42 is fixedly connected to the bottom of the concave hole 321; the third conductive member 61 has an elastic spiral structure, and one end of the third conductive member 61 is connected to the second socket 51. The second conductive member 42 and the third conductive member 61 adopt a spiral structure, so that the second conductive member 42 or the third conductive member 61 can have a larger elastic movement space under a certain axial length, and thus when severe vibration exists in an installation environment or a long lamp tube is bent obviously, stable electrical connection between the first conductive member 41 and the second conductive member 42 or between the third conductive member 61 and the fourth conductive member 62 can be continuously maintained, and the lighting stability of the lamp tube is ensured.

Referring to fig. 3, specifically, the material of the first conductive element 41, the second conductive element 42, the third conductive element 61, or the fourth conductive element 62 is a metal or an alloy. The first conductive member 41 is annular, and when the male butt joint 30 and the female butt joint 50 are at different fitting angles, the first conductive member 41 and the second conductive member 42 can be ensured to be contacted and abutted; the first conductive member 41 is fixed to an end of the boss 32 away from the first stem 31 by a screw. Fourth conductive member 62 is in the form of a plate and is fixedly attached to the end of center shaft 52.

Referring to fig. 7, the second socket 51 is provided with a cylindrical groove 511 for accommodating and further protecting the third conductive member 61.

Referring to fig. 3 and 6, in one embodiment, a plurality of fastening blocks 322 are uniformly distributed on the outer side of the convex base 32 along the circumferential direction; an L-shaped engagement groove 512 is formed in the second socket 51, and a part of the engagement groove 512 extends in the axial direction of the second socket 51 and the other part extends in the circumferential direction of the second socket 51; an opening of the fastening slot 512 faces the outside of the second socket 51; the fastening slots 512 are used for receiving the fastening blocks 322, so that the male and

female connectors

30 and 50 are relatively fixed in the axial direction.

After the second tube socket 51 and the first tube socket 31 are overlapped in the axial direction, the first tube socket 31 moves close to the second tube socket 51 along the axial direction, the buckling block 322 enters the buckling groove 512 from the opening of the buckling groove 512, and after the first tube socket 31 moves to the intersection of the axial extension part and the circumferential extension part of the buckling groove 512, the buckling block 322 is accommodated in the circumferential extension part of the buckling groove 512 through the relative rotation between the first tube socket 31 and the second tube socket 51 along the circumferential direction, so that the axial movement of the buckling block 322 relative to the female butt joint 50 is blocked, and the combined splicing between the male butt joint 30 and the female butt joint 50 can be simply and quickly completed; after the edges of the first tube seat 31 and the second tube seat 51 abut against each other, the matching between the fastening blocks 322 and the fastening grooves 512 which are uniformly distributed along the circumferential direction can prevent the spliced portion from bending due to the action of gravity, and further ensure the stability of the electrical contact between the male-side conductive assembly and the female-side conductive assembly.

In this embodiment, in order to simplify the mechanism of the male connector 30 and reduce the processing difficulty, three fastening blocks 322 are provided and are integrally formed with the boss 32.

The axial plate 513 and the circumferential plate 514 have an effect of forming a fastening groove 512, and after the fastening block 322 rotates in place along the female butt joint 50, the fastening block 322 is accommodated in the groove in an interference fit manner through the clamping grains 323, so that the angle of the fastening block 322 relative to the female butt joint 50 can be locked, and the automatic release of the splicing between the male butt joint 30 and the female butt joint 50 is avoided.

Referring to fig. 6, in the present embodiment, the axial plate 513, the circumferential plate 514 and the second socket 51 are integrally formed. Specifically, the locking particles 323 are disposed on a side of the fastening block 322 close to the first socket 31, and the groove is disposed on a side of the circumferential plate 514 facing the circumferential extension of the fastening groove 512.

female connectors

30 and 50 are relatively fixed.
