[0022] like Figure 1-Figure 2The figures are respectively a schematic diagram of the structure of a dual-cable lead-out electromagnet provided by the present invention and its exploded diagram. The dual-cable lead-out electromagnet comprises a housing 1, a housing 2 3 and a cable connector 5. An armature 13 is provided inside the housing 1, an electromagnetic coil 2 is provided outside the armature 13, a push rod 14 is provided inside the armature 13, an iron core 12 is installed in the inner cavity of the electromagnetic coil 2 and is connected to the push rod 14 and can slide axially. The push rod 14 extends through the armature 13 for outputting thrust. The interior of the housing 2 3 is provided with a lower circuit board 401, an upper circuit board 403 and a dial switch circuit board 7 from bottom to top. The connection of the electromagnetic coil 2 is arranged in the following order: The wire terminals are connected to the lower circuit board 401, which is connected to the upper circuit board 403 via spacers 402. The upper circuit board 403 and lower circuit board 401 are also connected via multiple pins. The lower circuit board 401 is connected to the housing 1 via spacers 402. The lower circuit board 401 is provided with a cable connector, which is connected to the DIP switch circuit board 7 via cables. The top of the housing 2 (3) is provided with a top cover 6, and the DIP switch circuit board 7 is located below the top cover 6 and connected to the housing 2 (3). The top cover 6 is conveniently opened in this utility model, and the digital electrical parameters of the electromagnet can be adjusted by adjusting the DIP switches on the DIP switch circuit board 7. The housing 2 (3) is connected to the top of the housing 1. A cable connector 5 is connected to the same side of each housing 1 and housing 2 (3). The upper circuit board 403 is connected to both cable connectors 5 via cables 15. The armature 13, electromagnetic coil 2, push rod 14, and iron core 12 are each two in number and symmetrically arranged within the housing 1. The upper circuit board 403 is connected to the spacer 402 via screw 1 404. The DIP switch circuit board 7 is connected to the housing 2 3 via screw 2 11.

[0023] The working principle of this utility model is:
[0024] The external control signal cable is connected to the upper circuit board 403 via the cable connector 5. The upper circuit board 403 transmits the signal to the lower circuit board 401 via the pins. The lower circuit board 401 analyzes the signal and converts it into a current signal, which is then transmitted to the electromagnetic coil 2. When the electromagnetic coil 2 is loaded with current, it generates a magnetic field, which polarizes the armature 13 and the iron core 12. As a result, the iron core 12 is attracted to the armature 13 under the action of the magnetic force. The movement of the iron core 12 drives the movement of the push rod 14, thereby outputting mechanical force. The same process applies to the two coils.
[0025] The utility model has a simple structure, ingenious design, reliability and durability, high safety, and the dual-outlet design can greatly facilitate the digital upgrade of the electromagnet. It has broad application prospects and is conducive to popularization and application.
