The two magnetic parts 4 are magnetic blocks, located at both ends of the insulating protective plate 5, and the magnetic shell is adsorbed in the magnetic track by the magnetic parts 4. The magnetic part 4 is fixed by screws. The magnetic part 4 and the insulating protective plate 5 are installed separately, and there is no need to set a matching assembly structure between them, which simplifies the structure. The insulating protective plate 5 and the magnetic part 4 cover the circuit board 2 inside, protecting the circuit board 2, making it more beautiful and safe.

[0031] The bottom surface of the mounting groove 11 is recessed with a receiving groove 13, and the front of the circuit board 2 faces the bottom surface of the mounting groove 11. The electronic components on the front of the circuit board 2 are received in the receiving groove 13, so that the electronic components are protected. The circuit board 2 is placed on the bottom surface of the mounting groove 11, so that the circuit board 2 is placed stably, which facilitates the installation of the circuit board 2. The insulating protective plate 5 and the magnetic member 4 are laid flat on the back of the circuit board 2 to cover the circuit board 2. The insulating protective plate 5 corresponds to the position of the electronic components of the circuit board 2, which can prevent outsiders from touching the part of the circuit board where the electronic components are located, thereby preventing electric shock.

[0037] A limiting recess 22 corresponding to the vertical portion of the conductive connecting pin 32 is provided on the side of the circuit board 2. The vertical portion of the conductive connecting pin 32 is placed in the limiting recess 22, so that the elastic conductive component 3 is limited in the length direction of the magnetic shell and is not easily displaced or deformed left and right.

[0038] The side of the insulating protection plate 5 is provided with a recess 51 corresponding to the elastic conductive member 3. The wall of the recess 51 corresponding to the rear of the vertical portion of the conductive connecting foot 32 is a limiting wall, which is used to prevent the elastic conductive member from being excessively squeezed inward and prevent excessive deformation.

[0039] The magnetic shell can be applied to a track power supply or a magnetic lamp body. When applied to a magnetic lamp body, a light source is installed in the magnetic shell. When applied to a track power supply for electrically connecting the power supply and the magnetic track, no other structure is required at the front end of the magnetic shell. When applied to a track power supply for electrically connecting the magnetic track and the lamp body, a connection structure and a wire-passing portion for connecting to the lamp body are provided at the front end of the magnetic shell. Figure 8 As shown, the magnetic housing in this embodiment is used to electrically connect the magnetic track and the lamp body 6.
