[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0015] See also Figure 1-2 A frame-type electromagnet convenient for wiring comprises a support frame 1, a coil 2, a moving iron core 3 and a wire 4; the support frame 1 is a closed-loop rectangular frame, an axial hole for matching the moving iron core is provided on the support frame 1, the coil 2 is wrapped around the moving iron core 3, the wire 4 is connected to the coil, a threading hole 5 is provided on the side of the support frame 1, and a wiring assembly 6 is arranged outside the threading hole 5, the wiring assembly 6 comprises a box body 61, the box body 61 is fixedly connected to the support frame 1 by bolts 62, a through hole 63 is provided on the side of the box body 61, and the through hole 63 A torsion spring shaft 64 is arranged inside, a turntable 65 is arranged outside the torsion spring shaft 64, a pair of terminals 66 are arranged horizontally through the turntable 65, the inner ends of the terminals 66 are fixedly connected to the wire 4, an upper receiving groove 67 is arranged at the upper part of the through hole 63, the upper receiving groove 67 is connected to the through hole 63, and the left side wall of the upper receiving groove 67 limits the rotation of the terminal 66, a lower receiving groove 68 is arranged at the lower part of the through hole 63, the lower receiving groove 68 is also connected to the through hole 63, and the right side wall of the lower receiving groove 68 also limits the rotation of the terminal 66. Specifically, when an external wire is needed, the turntable 65 is turned to pull out the terminal 66 (see Figure 1 ), and then connect the terminal 66 to the wire. After the connection is completed, release the turntable 65, and the turntable 65 is reset under the action of the torsion spring 64, hiding the terminal 66 in the upper receiving groove 67 (see Figure 2 ), which protects it and has less contact with the outside world. Compared with the connection method of soldering, it is not easy to fall off; the terminal 66 is a threaded terminal, which ensures that the wire can be tightly rolled into it and then tightened and fixed by a nut; the upper receiving groove 67 also has the function of placing the wire connection.

[0016] In this embodiment, the rotation angle of the torsion spring shaft 64 is 90°, which ensures that the terminal 66 can be rotated into place, which is convenient for external wire connection.

[0017] In this embodiment, the outer side surface of the turntable 65 is exposed outside the box body 61, which is convenient for turning the turntable 65 and better operation.
