As shown in FIGS. 1-4:
in one aspect of the present disclosure, there is provided a multi-section type electric wire connecting device including:
a first connector assembly detachably connected to a first electric wire 3 and a second electric wire 4 at both sides thereof, capable of forming a conductive electrical connection between the first electric wire 3 and the second electric wire 4, and having a detachable first split structure; and
the second joint component 2 is arranged on the outer side of the first joint component in a sealing manner and is provided with a detachable second split structure;
wherein the at least one detachable portion of the first split structure coincides with the at least one detachable portion of the second split structure.
The first joint assembly and the second joint assembly 2 are both provided with detachable structures, and at least one detachable part of each of the first joint assembly and the second joint assembly is overlapped with at least one detachable part of each of the second joint assembly and the second joint assembly, so that when the segmented electric wire is connected or detached, the first joint assembly and the second joint assembly 2 can be synchronously operated at the inner layer and the outer layer of the same detachable part, the frequent detachment of the connecting structure in the connecting or detaching process is avoided, the structure of the connecting device is simplified, and the working efficiency is greatly improved.

Based on this, the first flange joint 22 and the first receiving hole 213 are perpendicular to the first side surface 211, and the second flange joint 23 and the second receiving hole 214 are perpendicular to the second side surface 212, so that the first flange joint 22 and the second flange joint 23 can be more accurately aligned in mounting positions, and the mounting structure of the first flange joint 22 and the second flange joint 23 is less likely to interfere with the first receiving hole 213 and the second receiving hole 214 when the first flange joint 22 and the second flange joint 23 are mounted on the center connection block 21.
In some embodiments, the first wire 3 is divided into a connection portion a inside the first channel 221 and a non-connection portion b outside the first channel 221 along the extending direction thereof, the second wire 4 is divided into a connection portion a inside the second channel 231 and a non-connection portion b outside the first channel 221 along the extending direction thereof, the first wire 3 and the second wire 4 are disposed along a reference line c at the non-connection portion b, and the center connection block 21 is capable of making the first wire 3 form a first set angle between the connection portion a and the non-connection portion b and making the second wire 4 form a second set angle between the connection portion a and the non-connection portion b.
Further, in some embodiments, the center connector block 21 includes a prism structure having a trapezoidal cross section, two waists of the trapezoid respectively correspond to the first side surface 211 and the second side surface 212, and the trapezoidal cross section of the center connector block 21 is disposed with a lower base away from the reference line c, so that the first wire 3 and the second wire 4 are deviated from the reference line c at the connection point a.
The second joint component 2 can respectively enable the extending direction of the first electric wire 3 to be a first set angle between a joint a and a non-joint b, and enable the extending direction of the second electric wire 4 to be a second set angle between the joint a and the non-joint b, so that the first electric wire 3 and the second electric wire 4 have a certain inclination angle relative to the original extending direction, and the hose can be more attached to a winding surface when being wound.
And a prism structure with a trapezoidal section is used as the central connecting block 21, so that the first electric wire 3 forms the first set angle at the connecting position a, the second electric wire 4 forms the second set angle at the connecting position a, the connected electric wire is more suitable for the radian formed when the sectional electric wire is wound on the reel, and the connecting position a of the first electric wire 3 and the second electric wire 4 is extended out of the sectional electric wire, so that the disassembly and connection operation are more convenient.
At this time, the supplementary angle of the first set angle and the supplementary angle of the second set angle correspond to the complementary angles of the included angles between the two waists of the trapezoidal section and the lower bottom, respectively.

Further, in some embodiments, the mounting surface between the first plug connector 11 and the second plug connector 12 is overlapped with the first side surface 211, and the first plug connector 11 is further mounted to the central connecting block 21 by a bolt;
the first receiving hole 213 can partially receive the first plug 11, so that the bolt mounting surface between the first plug 11 and the center connection block 21 is recessed from the first side surface 211.
The mounting surface between the first and second connectors 11 and 12 is overlapped with the first side surface 211, so that when the segmented electric wire is connected or disconnected, the first connector assembly on the inner layer can be disconnected or connected at the same time under the condition that only the first side surface 211 of the second connector assembly 2 on the outer layer is detached to be operable. In addition, the bolt mounting surface between the first plug connector 11 and the center connection block 21 is spaced apart from the first side surface 211, so that the bolt can be prevented from interfering with the first flange joint 22 to be assembled on the first side surface 211.
Further, in order to further simplify the structure of the connection device and prevent the first connector assembly from moving back and forth in the second connector assembly 2, in some embodiments, the mounting surface between the first connector 11 and the second connector 12 is overlapped with the first side surface 211, and the first connector 11 is further mounted to the center connection block 21 by a screw-fit manner.
