[0002] A coil lead is a wire connecting a coil to a power source or other devices, and is used to transmit current or signals.
[0003] When manufacturing coil leads, different materials, processes and connection methods can be adopted. For example, some coil leads may be made of metal materials such as copper or aluminum, and are connected to the coil by means of welding or crimping. In addition, according to specific application scenarios and requirements, aspects such as the length, diameter, and insulating layer of the coil leads may also vary.
[0004] The quality and reliability of coil leads have an important impact on the performance and service life of coils. Therefore, when manufacturing and using coils, it is necessary to select appropriate coil leads and connection methods, and operate strictly in accordance with relevant standards and specifications to ensure the safety and stability of coils.
[0005] Currently, during the actual assembly of coils, since the pads are flush with the coil surface, but the coil leads are actually at least one wire diameter higher than the plane, resulting in interference between the leads and the FPC, and manual wire arrangement is required, which is rather cumbersome.

[0029] As Figures 1 to 4 shown, the present utility model provides a novel lead truncation structure.
[0030] Specifically, as Figures 1 - 4 shown, it includes a tangent forming jig and a die pressing plate mounted thereon for limiting the lead. The tangent forming jig includes a base platform 1 with an overall rectangular table structure. A protrusion 2 is integrally formed in the middle of the base platform 1. A wire threading hole 3 for the lead to pass through is provided on the protrusion 2. Knife-edge truncation positions 4 are provided on both the front side and the rear side of the top surface of the protrusion 2. A truncation block 5 for cooperating with a cutting knife is provided on the top surface of the knife-edge truncation position 4.
[0031] The die pressing plate includes a plate body 7 fixedly installed on the top surface of the convex part 2, and a clearance groove 8 for the lead wire to pass through is integrally formed at the position of the plate body 7 corresponding to the wire passing hole 3.
[0032] In the present utility model, the lead wire is inserted from below the base 1 into the convex part 2 and passes out through the wire passing hole 3, and then the lead wire is led out from the clearance groove 8, and then the lead wire is folded to the cutting block 5 provided at the cutting position 4 of the blade. The lead wire is cut by using a cutting tool in cooperation with the cutting block 5. In order to solve the interference defect, this lead wire cutting structure effectively solves the interference risk with the FPC, meeting the assembly requirements of the lead-out wire being flush with the coil surface and being bent and cut off.
[0033] Furthermore, as a specific implementation manner of the present utility model, the present utility model provides a novel lead wire cutting structure.
[0034] Specifically, as Figure 2 shown, mounting holes 6 are formed on the top surface of the base 1, the number of the mounting holes 6 is two, and the two mounting holes 6 are symmetrically arranged. The provided mounting holes 6 facilitate the installation of the base 1 at a specified position.
[0035] As Figure 2 shown, two wire passing holes 3 are formed, and the two wire passing holes 3 are arranged along the central axis of the convex part 2, and their positions correspond to the cutting position 4 of the blade. Through the cooperation of the symmetrically arranged wire passing holes 3, the cutting position 4 of the blade and the cutting block 5 on the convex part 2, when the wire passing holes 3, the cutting position 4 of the blade and the cutting block 5 on one side of the convex part 2 are damaged after long-term cutting of the lead wire, the plate body 7 can be replaced to the other side of the convex part 2 for continuous use, extending the service life of this lead wire cutting structure.
[0036] Furthermore, as a specific implementation manner of the present utility model, the present utility model provides a novel lead wire cutting structure.

The position of the avoidance groove 10 corresponds to the knife-edge truncation position 4, and the size of the avoidance groove 10 is adapted to the knife-edge truncation position 4. By providing the avoidance groove 10, the knife-edge truncation position 4 and the truncation block 5 on one side of the protrusion 2 can pass through the avoidance groove 10, avoiding the blockage of the plate body 7 by the knife-edge truncation position 4 and the truncation block 5 during the installation process.
[0040] As Figure 4 As shown, the plate body 7 is made of stainless steel, and a through hole 9 is formed through the rear side of the plate body 7.
