And because the mounting piece can form a snap connection with the tube sleeve, and the first terminal and the mounting piece are connected by an elastic piece, after the mounting piece is connected to the tube sleeve, the elastic piece is squeezed between the mounting piece and the first terminal, so that the first terminal is subjected to pressure from the elastic piece, so that the first terminal stably abuts against the second terminal, ensuring the stable connection between the electrical connector and the electrical interface.

[0012] Optionally, the connecting tube has a second card interface, and the second terminal is provided with a card connecting piece, and the card connecting piece can be card-connected with the second card interface.

[0015] By adopting the above technical solution, the unlocking block can press the clamping piece on the outside of the pipe sleeve, thereby releasing the clamping connection between the clamping piece and the second clamping interface, thereby completing the release of the clamping connection between the second terminal and the connecting pipe on the outside of the pipe sleeve, thereby improving the disassembly and assembly efficiency.

When the limit block is aligned with the connecting hole, the mounting piece can pass through the limit block. When the limit block is rotated to align with the limit groove, the limit block clamps the mounting piece, so that the mounting piece and the first terminal clamp the elastic piece between them.

[0026] Optionally, outer sides of the limiting groove and the connecting groove are both provided with inclined surfaces, and the inclined surfaces are used to guide the limiting block to slide into the inclined surfaces.

[0027] By adopting the above technical solution, the inclined surface is inclined in the direction of the connecting hole, so that when the mounting piece is rotated relative to the first wiring harness, even if the position is not aligned with the limiting groove, the inclined surface can slide the limiting block into the limiting groove, thereby ensuring that the mounting piece and the limiting block can be stably connected and preventing the limiting block from passing through the connecting hole.

[0040] The present application is further described in detail below in conjunction with the accompanying drawings.

[0041] A split wiring harness connection structure, referring to Figure 1 , including a connecting pipe 1, a connecting sleeve assembly 2, a first connecting assembly 3 and a second connecting assembly 4. The connecting sleeve assembly 2 can be sleeved on the outside of the connecting pipe 1, the second connecting assembly 4 is installed in the connecting sleeve assembly 2 by connecting with the connecting pipe 1, and the first connecting assembly 3 can be connected with the connecting sleeve assembly 2, thereby realizing electrical connection with the second connecting assembly 4 in the connecting sleeve assembly 2.

[0042] Reference Figure 1 , Figure 2 and Figure 3The connecting tube 1 is relatively long, and one end of the connecting tube 1 is inserted into the connecting sleeve assembly 2. The connecting sleeve assembly 2 includes a sleeve 21 and a locking device 22. The connecting tube 1 passes through the locking device 22, and the end of the connecting tube 1 is located in the sleeve 21. The second connecting assembly 4 includes a second terminal 41 and a second wiring harness 42, wherein the second terminal 41 is installed and connected to the end of the connecting tube 1, and the second wiring harness 42 is located on the inner side of the connecting tube 1 and connected to the second terminal 41, so that the second wiring harness 42 can extend along the direction of the connecting tube 1 under the protection of the connecting tube 1. The part of the connecting tube 1 located outside the connecting sleeve assembly 2 is provided with a connecting port 14, and the second wiring harness 42 can pass through the connecting port 14 and pass through the connecting port 14 so that the second wiring harness 42 can extend its branches outward, thereby improving the applicability of the connecting structure.

[0043] Reference Figure 3 , a clamping piece 44 is provided on each side of the second terminal 41, and the end of the clamping piece 44 has a clamping structure protruding outward and can be pressed inward. The end of the connecting tube 1 located in the pipe sleeve 21 has a corresponding second clamping interface 11, and the second terminal 41 can be inserted into the end of the connecting tube 1, so that the clamping pieces 44 on both sides are clamped with the second clamping interface 11, so that the second terminal 41 cannot fall off the connecting tube 1, and the end of the connecting tube 1 can abut the outside of the second terminal 41, so that the second terminal 41 is installed on the connecting tube 1 and located in the pipe sleeve 21. An unlocking block 24 is provided on the pipe sleeve 21. When the connecting tube 1 and the second terminal 41 are installed, the position of the unlocking block 24 corresponds to the position of the clamping piece 44 and the second clamping interface 11. The unlocking block 24 can move inward relative to the pipe sleeve 21, thereby pressing the clamping piece 44 to release the clamping relationship between the clamping piece 44 and the second clamping interface 11. By providing an unlocking member, the second terminal 41 and the connecting tube 1 can be separated in the pipe sleeve 21, thereby improving the separation efficiency. In addition, a second positioning block 45 is provided on the side of the second terminal 41, and a second positioning groove 13 corresponding to the second positioning block 45 is provided on the side of the connecting tube 1. When the second terminal 41 is installed in the connecting tube 1, the second positioning block 45 is inserted into the second positioning groove 13, thereby ensuring that the second terminal 41 and the connecting tube 1 are connected in the correct direction, thereby improving the accuracy of the connection.

[0044] Reference Figure 6 and Figure 7The locking device 22 is arranged at one end of the pipe sleeve 21, and the connecting pipe 1 passes through the locking device 22. The connecting pipe 1 is provided with a locking groove 12. The locking device 22 locks the connecting pipe 1 in the connecting sleeve assembly 2 by engaging the locking groove 12. The locking device 22 includes a locking ring 221, a locking piece 222 and a locking spring 223. The locking piece 222 is arranged in the locking ring 221 and can move relative to the locking ring 221. The connecting pipe 1 passes through the locking ring 221 and the locking piece 222. The locking piece 222 can be engaged in the locking groove 12, so that the connecting pipe 1 cannot move relative to the connecting sleeve assembly 2, thereby fixing the connecting pipe 1 and the second terminal 41 installed on the connecting pipe 1 in the pipe sleeve 21. The locking springs 223 are connected to both sides of the locking piece 222. The other end of the locking spring 223 is connected to the inner side of the locking ring 221, so that the locking piece 222 can be engaged in the connecting groove when there is no external force, thereby locking the connecting pipe 1. The locking ring 221 has an unlocking opening 224 that can expose the locking piece 222. Through the unlocking opening 224, the user can push the locking piece 222 to move, thereby releasing the engagement between the locking piece 222 and the locking groove 12. Through the locking device 22, the connection pipe 1 can be fixed and separated quickly and conveniently, and the second terminal 41 fixedly arranged on the connection pipe 1 can be further installed, so that the connection structure can be stably installed and efficiently separated.

[0045] Reference Figure 4 and Figure 5The first connection component 3 is connected to one end of the pipe sleeve 21. The first connection component 3 includes a first terminal 31, a first wiring harness 32, an elastic member 33 and a mounting member 34. The first wiring harness 32 is connected to the first terminal 31. The elastic member 33 and the mounting member 34 are both mounted on the first wiring harness 32. The elastic member 33 is sandwiched between the first terminal 31 and the mounting member 34. The mounting member 34 can slide on the first wiring harness 32 and can rotate around the first wiring harness 32. The first terminal 31 has a top connection, and the second terminal 41 has a corresponding electrical interface 43. The electrical connector 311 can be connected to the electrical interface 43, so as to conduct the first wiring harness 32 and the second wiring harness 42. The first terminal 31 can be inserted into the pipe sleeve 21, so as to abut against the second terminal 41, so that the electrical connector 311 is connected to the electrical interface 43. The mounting member 34 is provided with a clamping block 341, and the pipe sleeve 21 is provided with a second clamping interface 11 corresponding to the clamping block 341. The clamping block 341 is clamped with the second clamping interface 11, so that the mounting member 34 is installed and connected to the pipe sleeve 21. When the mounting member 34 is installed on the pipe sleeve 21, the first terminal 31 abuts against the second terminal 41. At this time, the mounting member 34 and the first terminal 31 will squeeze the elastic member 33, so that the first terminal 31 is pushed by the elastic member 33 and can maintain abutment with the second terminal 41, so that the electrical connector 311 and the electrical interface 43 can maintain a stable connection. Mechanical connections are prone to loosening during use, but the elastic member 33 maintains thrust between the mounting member 34 and the first terminal 31, so that even if the connection between the mounting member 34 and the pipe sleeve 21, or the connection between the second terminal 41 and the connecting pipe 1, is loosened, the elastic member 33 can release part of the elastic potential energy, thereby maintaining the pressure of the mounting member 34 on the first terminal 31, ensuring that the first terminal 31 is tightly abutted against the second terminal 41, and ensuring that the electrical connector 311 and the electrical interface 43 are tightly connected. In addition, by separating the clamping block 341 and the first clamping interface 23, the mounting member 34 can be separated from the pipe sleeve 21, thereby quickly separating the first connecting assembly 3 and the second connecting assembly 4, and maintaining a tight connection while being able to be quickly replaced.

[0046] Reference Figure 4 and Figure 5The mounting member 34 is provided with a first positioning block 312, and a third positioning block 342 is provided on the mounting member 34. The pipe sleeve 21 is provided with a first positioning groove 26, and the first positioning groove 26 is a long strip-shaped slot. Both the first positioning block 312 and the second positioning block can be inserted into the first positioning groove 26, so that the first terminal 31 and the mounting member 34 are stably and accurately mounted on the pipe sleeve 21, ensuring the stable connection between the electrical connector 311 and the electrical interface 43. The first wiring harness 32 is provided with a limit block 321, which is a structure protruding on both sides. Corresponding to the shape of the limit block 321, the mounting member 34 is provided with a connecting hole 343, and the limit block 321 can pass through the mounting member 34 through the connecting hole 343. Limiting grooves 344 are provided on both sides of the connecting hole 343. The size of the limiting grooves 344 also corresponds to the limiting blocks 321. When the mounting member 34 rotates relative to the first wiring harness 32, the positions corresponding to the limiting blocks 321 protruding on both sides change from the connecting hole 343 to the limiting grooves 344. The limiting grooves 344 can be engaged with the limiting blocks 321, so that the mounting member 34 cannot pass over the limiting blocks 321, thereby achieving the purpose of limiting. Inclined surfaces 345 are provided on the outer sides of the connecting hole 343 and the limiting grooves 344. The inclined surfaces 345 are inclined toward the connecting hole 343, so that when the mounting member 34 rotates relative to the first wiring harness 32, even if the position is not aligned with the limiting grooves 344, the inclined surfaces 345 can slide the limiting blocks 321 into the limiting grooves 344, thereby ensuring that the mounting member 34 and the limiting blocks 321 can be stably engaged, and preventing the limiting blocks 321 from passing through the connecting hole 343.

[0047] The implementation principle of the embodiment of the present application is as follows: the split wiring harness connection structure is connected, the connection pipe 1 and the second connection assembly 4 are connected first, the second wiring harness 42 passes through the connection pipe 1 and passes out from the communication port 14, and the second terminal 41 is connected to one end of the connection pipe 1 by the second card interface 11 and the card plate 44. Then, the connection pipe 1 is fixed in the pipe sleeve 21 by the card plate 222 and the locking groove 12, so that the second terminal 41 is fixed in the pipe sleeve 21. On the other side of the sleeve 21, the first connecting component 3 is inserted into the sleeve 21, the electrical connector 311 on the first terminal 31 is connected to the electrical interface 43 on the second terminal 41, and after the first terminal 31 abuts against the second terminal 41, the mounting member 34 compresses the elastic member 33 inwardly, and the first connecting component 3 is mounted on the other end of the sleeve 21 by the clamping of the clamping block 341 and the first clamping interface 23, and the compressed elastic member 33 creates an outward pressure between the mounting member 34 and the first terminal 31, so that when the connection between the first terminal 31 and the sleeve 21 or the connection between the connecting tube 1 and the locking device 22 becomes loose or shifted in position, the elastic member 33 can maintain the abutment between the first terminal 31 and the second terminal 41, so that the electrical connector 311 and the electrical interface 43 remain tightly connected.

[0048] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks.
