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:

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.

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.

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.
