[0009] Furthermore, a top pressing plate is provided above the shell holder corresponding to the coil shell, and the top pressing plate is connected to a lifting drive.

[0010] Furthermore, a protruding block is arranged on the outer side of the coil housing, and a protruding groove is arranged on the housing holder corresponding to the protruding block.

[0011] Furthermore, a telescopic rod is connected to the rear side of the positioning claw.

[0012] Furthermore, the telescopic rod is fixedly connected with a sliding block, and the sliding block is slidably sleeved on the front and rear guide rails.

[0013] Furthermore, a return spring is connected to the lower end of the top plate on the side opposite to the rotating shaft.

[0014] Furthermore, an opening and closing handle is connected to the side of the top plate opposite to the rotating shaft.

[0015] Furthermore, the shell holder, positioning claws, wire clamps and top pressing plates are installed in one piece, and a plurality of shell holders, positioning claws, wire clamps and top pressing plates are arranged around the outer side of the dividing plate.

[0016] Furthermore, the housing base, positioning claws and wire clamps are all installed on the positioning base plate.

[0017] The advantages of the utility model are:

[0018] 1. Effectively fix and orient the conductors of the transformer housing and coil, and easily and quickly wrap the conductors around the terminals to complete the wiring operation.

[0019] 2. High positioning accuracy can improve winding processing efficiency and reduce winding defect rate.

[0032] like Figures 1 to 4 As shown, this embodiment provides a transformer branching line tooling fixture, including a shell holder 1, a coil shell 5 is installed in the shell holder 1, a wiring terminal 6 is arranged at the front end of the coil shell 5, and a positioning claw 2 is arranged on the left and right sides of the front end of the shell holder 1 corresponding to the wiring terminal 6. A wire clamp 3 is also arranged at the front end of the positioning claw 2, and the wire clamp 3 includes a bottom plate 301 and a top plate 302 which are fitted together, and a rotating shaft 303 is connected to one side of the top plate 302.

[0033] In actual use, first align one side of the terminal 6 of the coil housing 5 with the positioning claw 2 and place it in the housing holder 1, the coil housing 5 is fixed in the housing holder 1, and the terminal 6 is clamped and fixed by the positioning claws 2 on the left and right sides. Then put the coil of the transformer into the coil housing 5, pull out the wire 502, and clamp it in the wire clamp 3, so as to achieve accurate positioning of the wire 502 and the terminal 6, and facilitate the subsequent accurate winding of the wire 502 on the terminal 6.

[0034] A top pressing piece 4 is provided above the housing holder 1 corresponding to the coil housing 5, and the top pressing piece 4 is connected to a lifting drive 401. The liftable top pressing piece 4 can be lowered and pressed on the top of the housing holder 1 when the coil housing 5 and the coil and other mutual inductor components are placed, further improving the positioning stability and avoiding component deviation.

[0035] The outer side of the coil housing 5 is provided with a protruding block 501, and the housing holder 1 is provided with a protruding groove 101 corresponding to the protruding block 501. Since the butting positions of the protruding block 501 and the protruding groove 101 are fixed, the protruding block 501 and the protruding groove 101 that cooperate with each other can further improve the positioning speed, and avoid the position deviation of the connection terminal 6 when the coil housing 5 is sleeved on the housing holder 1.

[0036] The rear side of the positioning claw 2 is connected with a telescopic rod 201. The telescopic rod 201 is fixedly connected with a slider 202, and the slider 202 is slidably sleeved on the front and rear guide rails 203. The positioning claw 2 can move forward and backward to prevent the positioning claw 2 from getting stuck on the coil housing 5 when the coil housing 5 is taken out.

[0037] The lower end of the top plate 302 is connected to a return spring 7 on the side opposite to the rotating shaft 303. Since the wire clamp 3 needs to clamp the wire 502, the return spring 7 can be set to press the top plate 302 in the standby state to prevent the wire 502 from loosening.

[0038] The top plate 302 is connected to an opening and closing handle 8 on the side opposite to the rotating shaft 303. The opening and closing handle 8 facilitates external equipment and users to move the top plate 302 and take out the wire 502 to be wound.

[0039] The shell holder 1, the positioning claw 2, the wire clamp 3 and the top pressing plate 4 are integrally installed, and a plurality of shell holders 1, the positioning claw 2, the wire clamp 3 and the top pressing plate 4 are arranged around the outer side of the indexing plate 9. Arranging a plurality of fixture units on the indexing plate 9 can realize the sequential transportation of the mutual inductor components along a plurality of workstations, and facilitates the use of automated equipment for the production of mutual inductors.

[0040] The housing base 1, the positioning claws 2 and the wire clamp 3 are all mounted on the positioning base 10. The positioning base 10 facilitates accurate alignment of the housing base 1, the positioning claws 2 and the wire clamp 3, and facilitates mass production of this embodiment.
