[0030] The above implementation mode is the core technical scheme of this embodiment. According to the flip connection formed between the first shell 1 and the second shell 2 through the flexible connecting part 3, during installation, the first shell 1 and the second shell 2 are first flipped open and sleeved and installed between the corrugated tube and the connector, and then the first shell 1 and the second shell 2 are flipped closed together, and the first shell 1 and the second shell 2 in the closed state are fixed by the fixing structure 4 to form an integral tail clamp joint. In this way, after installation, the corrugated tube is installed in the first interface 5 of the tail clamp joint, and the connector is adapted to be connected in the second interface 6 of the tail clamp joint, so that the wiring harness between the corrugated tube and the connector is accommodated in the tail clamp joint, which plays a protective role for the wiring harness to avoid friction and scratch accidents caused by the exposure of the line. According to the flexible connecting part, the first shell and the second shell are formed as an integral structure, the structural stability is good, the processing is convenient, and the production cost is low. The tail clamp joint using this technical solution has a simple structure, is very convenient to install and disassemble, has high installation efficiency, and improves the wiring harness protection effect.

[0031] As a preferred embodiment, refer to Figure 2-3 The flexible connection part 3 is a flexible belt extending along the length direction of the first shell 1 and the second shell 2, and the two side edges of the flexible belt are respectively connected to the side surfaces of the first shell 1 and the second shell 2. This flexible belt is integrally injection-molded with the first shell 1 and the second shell 2, and as a deformable component, it not only realizes the integrated flip connection between the first shell 1 and the second shell 2, but also enhances the connection strength between the first shell and the second shell. Compared with the traditional chain or shaft hinge method, the flexible belt has a compact structure and does not require assembly, thereby reducing costs. The entire movement and force transmission is achieved by using the deformation of the flexible belt. There is no friction and wear in the transmission process, and it can also play an installation effect of vibration isolation, noise reduction and adjustment of installation errors, thereby improving the product performance. The tail clamp joint with this structure is more convenient to assemble and the production cost is greatly reduced.

[0032] Combine the following Figure 1-4 The specific setting method of the fixed structure is described in detail:

[0033] The fixing structure 4 is a snap-fit ​​structure arranged between the other side of the first shell 1 and the second shell 2. Specifically, the fixing structure 4 includes a plurality of snap-fit ​​bosses 42 or a plurality of elastic snap plates 41 arranged on the other side of the first shell 1, and a plurality of elastic snap plates 41 or a plurality of snap-fit ​​bosses 42 correspondingly arranged on the other side of the second shell 2. The elastic snap plate 41 is in a U-shaped structure and has a snap-fit ​​groove that buckles against the snap-fit ​​boss 42. The elastic snap plate 41 can be elastically deformed under pressure, and maintains close contact with the snap-fit ​​boss 42 by virtue of its own deformation force, so as to avoid the occurrence of the decoupling phenomenon, and the installation is stable. Therefore, when the first shell 1 and the second shell 2 are flipped and closed, the elastic snap plate 41 and the snap-fit ​​boss 42 form a fixed snap-fit ​​fit, so as to realize the closed and fixed connection of the first shell and the second shell, so as to assemble into a complete tail clip connector, so as to realize the sheathing and installation of the wire harness between the corrugated tube and the connector, and achieve the protective effect, and the installation is convenient and quick.

[0034] Although the fixing structure 4 preferably adopts a snap-fit ​​structure, it is not limited to the above one, and there may be other different installation methods. For example, the fixing structure is a riveted structure arranged between the first shell and the other side of the second shell, specifically, a rivet is used to achieve the fixed connection between the two shells; or, the fixing structure may also be selected as a screw structure arranged between the first shell and the second shell, specifically, a mounting boss is arranged on the other side of the first shell and the second shell, and the two mounting bosses are fixedly connected by the screw structure, thereby achieving the fixed connection between the first shell and the second shell; or, the fixing structure may also adopt an ultrasonic welding structure to achieve the fixed connection between the first shell and the second shell in a closed state. Those skilled in the art can make a choice of the specific structure of the fixing structure according to the above description, and will not be described one by one here.

[0035] In this embodiment, combined with Figure 1-2As shown, the tail clamp body 10 formed by the first shell 1 and the second shell 2 fixedly connected comprises a main clamp body 101 in a square shape, and a circular tube part 102 connected to one end of the main clamp body 101, the other end of the main clamp body 101 is provided with a second interface 6 adapted to be connected to the connector, and the circular tube part 102 is provided with a first interface 5, wherein the first interface 5 is a round mouth shape suitable for connecting the corrugated pipe, and the inner wall of the circular tube part 102 is provided with a plurality of annular ridges 103 spaced along its axial direction, and the plurality of annular ridges 103 are matched to abut against the corrugated grooves on the outer wall of the corrugated pipe. With this structural arrangement, when installing and connecting the corrugated pipe, the first shell 1 and the second shell 2 are closed and fixed, so that the plurality of annular ridges 103 are correspondingly stuck in the corrugated grooves on the outer wall of the corrugated pipe, thereby realizing the installation connection between the tail clamp connector and the corrugated pipe, which can effectively prevent the corrugated pipe from being separated from the tail clamp connector when plugging and unplugging, and the installation is stable and reliable.

[0036] It is further preferred that the first interface 5 is in the shape of a rectangular opening, and an annular baffle 104 is provided in the main clamp body 101 opposite to the first interface 5, and the annular baffle 104 plays a positioning role in the distance at which the connector is installed in the first interface 5, and a clearance groove 8 and a mounting card hole 9 for matching with the connector are provided on the side of the main clamp body 101, and the mounting card hole 9 is respectively provided on the first shell 1 and the second shell 2, and the clearance groove is used to make way for the pressing buckle plate on the connector. With this structural arrangement, when installing the connector, the first shell 1 and the second shell 2 are flipped and closed to form a main clamp body 101 that surrounds and clamps the connector. At this time, the connector is just connected to the second interface 6 of the tail clamp connector. Correspondingly, a mounting card block is provided on the connector that is matched with the mounting card hole 9 on the main clamp body, thereby realizing the installation connection between the tail clamp connector and the connector, which can effectively avoid the situation that the connector is separated from the tail clamp connector when plugging and unplugging, and the installation is stable and reliable. The tail clamp connector using this structural design can quickly realize the installation connection between the connector and the corrugated pipe, thereby improving the convenience of assembly.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
