The shell 2 is fixedly connected to the base 1, and a slot 3 is opened on the shell 2. A through slot 5 is opened in the slot 3. The through slot 5 is connected to the circuit board, and the device is arranged in the through slot 5: a charging spring piece that is easy to install includes a conductive component, and the conductive component is provided with a group. The conductive component includes a first connecting part 4, a second connecting part 10 and a contact part 12. The second connecting part 10 is fixedly arranged between the first connecting part 4 and the contact part 12, and the contact part 12 is used to contact with the circuit board. The first connecting part 4 and the second connecting part 10 are used to provide a support point for the charging device, and the auxiliary contact part 12 is in contact with the circuit board to conduct the charging circuit; the The first connection part 4, the second connection part 10, and the contact part 12 are conductive metal plates, the contact part 12 is a straight plate and is arranged horizontally, the second connection part 10 and the first connection part 4 are arc-shaped plates, a recessed part 13 is formed at the fixed connection between the contact part 12 and the second connection part 10, and a protruding part 14 is formed at the fixed connection between the second connection part 10 and the first connection part 4, the protruding part 14 is at an obtuse angle with the opening downward, and the recessed part 13 is at an obtuse angle with the opening upward; the protruding part 14 can push the contact part 12 downward under the pressure of the charging device until it is connected to the circuit board; the purpose of the recessed part 13 and the protruding part 14 being at an obtuse angle is to reduce the deformation elastic force when the spring piece is pressed, so that the stress distribution at the connection is more uniform, which can reduce the stress concentration phenomenon, reduce the occurrence of elastic deformation, extend the service life of the spring piece, and improve its stability and reliability;

[0026] As an implementation method in this embodiment, one end of the first connecting portion 4 is fixedly connected to an insulating portion 9, and the insulating portions 9 that appear in pairs are slidably connected to an insulating plate 8. A limiting groove 6 is provided on the insulating plate 8, and a spring 7 is provided in the limiting groove 6. One end of the spring 7 is fixedly connected to the insulating portion 9, and the other end is fixedly connected to the bottom of the limiting groove 6. A pair of bolts 11 are threadedly connected to the insulating plate 8, and threaded holes matching the bolts 11 are correspondingly provided on the base 1.

[0028] Working principle:

[0029] The contact portion 12 is pressed against the lower end of the through slot 5, and a pair of rubber plates 15 are respectively pressed against the two sides of the through slot 5, and then the insulating plate 8 is fixedly connected to the base 1 by tightening the bolts 11; the charging device is pressed into the slot 3, and the charging device first contacts the protrusion 14. Under the pressure of the charging device, the protrusion 14 can push the contact portion 12 downward until it is connected to the circuit board and the circuit is connected; at the same time, pressing the protrusion 14 drives the spring 7 to contract and reduce the deformation of the spring. After charging is completed, the charging device is pulled out, and the spring is reset under the action of the spring 7 and its own elasticity.
