The embodiment of the invention provides an automatic splicing device for a branch circuit, which comprises a front clamping jaw 1 and a rear clamping jaw 2 which are arranged on the same slide rail component 3, wherein at least one of the front clamping jaw 1 and the rear clamping jaw 2 is connected to the slide rail component 3 in a sliding manner, as shown in fig. 1 to 9; a pressing fixing groove 101 is formed in the front clamping jaw 1, the pressing fixing groove 101 is smaller than the sum of cross sectional areas of the twisted electric wire and the twisted electric wire, one end of the twisted electric wire and a wire body of the twisted electric wire can be pressed and fixed together, and good electric connection between the twisted electric wire and the twisted electric wire is guaranteed. The rear clamping jaw 2 is internally provided with a rotatable rotary tile 4, the middle part of the rotary tile 4 is provided with a twisted groove 401 used for containing a twisted electric wire and a twisted wire groove 402 communicated with the twisted groove 401 and used for containing the twisted electric wire, the side edge of the rotary tile 4 is convexly provided with an annular rotary guide part coaxial with the twisted groove 401, and the rotary guide part is used for driving the twisted electric wire to be wound on the twisted electric wire. When the annular rotary guide part is driven to rotate by external force, the rotary tile 4 is driven to rotate together, and because one end of the stranded wire is fixed by the front clamping jaw 1, the stranded wire groove 402 and the stranded wire groove 401 are driven to do relative rotation motion, so that the automatic stranding of the branch circuit is realized, and the working efficiency of the electric wire stranding of the branch circuit is improved.

The rotation guide member has at least a rotation portion communicating with the twisted groove 401 and a guide limit portion communicating with the twisted groove 401.

The rotating part is in friction surface contact with a power output wheel 52 of a power driving part 5, and is used for driving the twisted wire to rotate around the twisted wire. Specifically, the outer peripheral surface of the rotating portion is abutted to the outer peripheral surface of the power output wheel 52 of the power driving component 5, the outer peripheral surface of the rotating portion is a friction surface, and the power output wheel 52 drives the rotating portion to rotate through friction force, so that the twisted wire is driven to rotate around the twisted wire.

The guide limiting part is axially and convexly arranged towards one side close to the front claw 1, the diameter of the guide limiting part is slightly larger than the maximum distance between the twisting groove 402 and the center of the rotating tile 4, and the guide limiting part is used for guiding the twisting electric wire to rotate on the twisted electric wire and limiting the maximum diameter of the winding of the twisting electric wire. When the twisted electric wire is driven to wind on the twisted electric wire, the twisted electric wire is guided to wind on the twisted electric wire under the limitation of the guide limiting part, so that not only is the winding tightness ensured, but also the twisted electric wire is only wound for one circle on the twisted electric wire with unit length. Furthermore, the guide limiting part ensures that the twisted electric wire is only wound on the twisted electric wire in unit length for one circle, so that when the twisted electric wire rotates around the twisted electric wire, a coil wound on the twisted electric wire of the twisted electric wire pushes the rotary tile 4 to move rightwards, namely the rear clamping jaw 2 is pushed to drive the sliding rail assembly 3 to move rightwards, and therefore the guide limiting part not only realizes circumferential guide, but also can realize axial guide.

When the rotary guide member rotates the rotary tile 4, the twisting groove 402 starts to rotate around the twisted groove 401, so that the twisted wire in the twisting groove 402 is driven to start to rotate around the twisted wire in the twisted groove 401, and then is wound on the twisted wire. When the twisted wire is a single wire, the structure of the twisted wire wound around a coil is as shown in fig. 9 (a); when the twisted wire is one of the two-strand wires, the structure in which it is twisted around the coil is shown in fig. 9 (b).

Specifically, the power driving part 5 is fixedly connected with the rear jaws 2 through a connecting fixing seat and can slide on the slide rail assembly 3 together with the rear jaws 2, the power output end 51 of the power driving part 5 realizes power transmission with the rotating ring 41 through a power output wheel 52, specifically, as shown in fig. 3, the power output end 51 of the power driving part 5 is in friction abutting connection with one side of the power output wheel 52, the other side of the power output wheel 52 is in friction abutting connection with the rotating ring 41, and the annular surfaces of the power output end 51, the power output wheel 52 and the rotating ring 41 are friction surfaces, so that kinetic energy transmission is realized through friction force.

When the power driving part 5 drives the rotating ring 41 to rotate through the power output wheel 52, the twisted wire is driven to wind on the twisted wire, and is limited by the guiding limit ring 42, the twisted wire winds on the twisted wire with a unit length for only one turn, and the wound coil pushes the rotating shoe 4 to move rightwards, namely, the rear jaw 2 is pushed to drive the sliding rail assembly 3 to slide rightwards relative to the front jaw 1.

The rotary guide part can also adopt other deformation structures, for example, the rotary guide part can be a ring part which is axially and convexly arranged from the rotary tile 4 to one side close to the front clamping jaw 1, and the circumferential outer side of the ring part forms a rotary part which is in friction butt joint with a power output wheel 52 of the power driving part 5 and is used for driving the stranded wire to rotate around the stranded wire; the inner side of the circumference of the ring part forms a guide limiting part which is used for guiding the twisted electric wire to rotate on the twisted electric wire and limiting the maximum diameter of the winding of the twisted electric wire.

When the rear jaw 2 is closed, the rotary shoe 4 can rotate inside the rear jaw 2 under the external force. As shown in fig. 7 and 8 in particular, an arc-shaped slot 201 with a notch smaller than the maximum width of the groove body is concavely arranged on the upper portion 21 of the rear jaw, the slot 201 is coaxially arranged with the rotating tile 4, an arc-shaped convex rail 403 matched with the slot 201 is arranged on the periphery of the upper portion 43 of the rotating tile, and the convex rail 403 is arranged in the slot 201 in a sliding fit manner and can freely rotate around a twisted slot 401 of the rotating tile 4.

However, in order to prevent the upper swivel shoe portion 43 from sliding out of the slot 201 and falling off from the upper rear jaw portion 21 when the rear jaw 2 is in an open state, an anti-falling assembly is further disposed between the upper rear jaw portion 21 and the upper swivel shoe portion 43 for preventing the upper swivel shoe portion 43 from sliding out of the upper rear jaw portion 21.
