[0023] Specifically, the base 3 limits the power chip body 1, and by twisting the upper cover 2, the bottom of the upper cover 2 is fitted with the upper part of the base 3. At this time, the locking block 10 at the bottom of the upper cover 2 will be inserted into the locking groove 8, and then the upper cover 2 is pushed to move, so that the upper cover 2 drives the locking block 10 to move, so that the locking plate 9 blocks the extension of the locking block 10, and when the upper cover 2 moves, it will also pull the connecting rod 7, so that the connecting rod 7 drives the slider 6 to move in the sliding groove 5, so that the locking block 10 cooperates with the locking plate 9 to pull and fix one end of the upper cover 2, and the slider 6 cooperates with the connecting rod 7 to pull the other end of the upper cover 2, so that the upper cover 2 and the base 3 are fixed, so that the upper cover 2 and the base 3 cover the power chip body 1, so that the upper cover 2 and the base 3 provide anti-electromagnetic protection for the power chip body 1;

[0024] By sliding the upper cover 2 in the opposite direction, the upper cover 2 will be reset and twisted under the torsion of the connecting rod 7, so that the locking block 10 is pulled out of the locking groove 8. The connecting rod 7 is a "V"-shaped structure, so the middle part of the connecting rod 7 will provide space for the upper cover 2 to twist, thereby preventing the connecting rod 7 from being blocked by the base 3 and the upper cover 2, resulting in the upper cover 2 being unable to twist, thereby completing the opening of the upper cover 2.

[0025] Furthermore, the outer walls of the base 3 and the upper cover 2 are formed into a honeycomb structure, and the honeycomb structure formed by the base 3 and the upper cover 2 is used to reflect electromagnetic waves;

[0026] Specifically, the honeycomb structure formed by the base 3 and the outer wall of the upper cover 2 can refract and rebound electromagnetic waves multiple times, so that when the upper cover 2 and the base 3 are closed to cover the power chip body 1, the protection effect of the power chip body 1 is increased, the anti-electromagnetic interference effect of the power chip body 1 is increased, and the stability of the power chip body 1 during use is increased.

[0029] Furthermore, the upper cover 2 has symmetrically arranged limiting rollers 16 inside, which are used to limit the power chip body 1;

[0030] Specifically, the power chip body 1 is limited by the provided limiting rollers 16 , thereby increasing the stability of the connection between the power chip body 1 , the upper cover 2 and the base 3 when the upper cover 2 and the base 3 are closed.

[0031] Furthermore, a symmetrically arranged pressure groove 12 is formed on the inner wall of the upper cover 2. A second spring 14 is fixedly connected to the inner end wall of the pressure groove 12. A pressure block 15 is slidably connected to the inner wall of the pressure groove 12.

The rotating shafts at both ends of the limiting roller 16 are rotatably connected to the outer wall of the pressure block 15.

[0032] Specifically, the second spring 14 pushes the pressure block 15 so that the pressure block 15 pushes the limiting roller 16 to abut against the top of the power chip body 1, thereby increasing the fitting effect of the limiting roller 16 on the power chip body 1 when the upper cover 2 and the base 3 are closed, and increasing the stability between the upper cover 2 and the base 3 and the power chip body 1 when they are closed.

[0033] Furthermore, the limiting roller 16 is made of rubber. When the limiting roller 16 contacts the top of the power chip body 1, the limiting roller 16 is compressed and deformed to fit the top of the power chip body 1.

[0034] Specifically, the limiting roller 16 is made of rubber, so that when the limiting roller 16 is in contact with the power chip body 1, the limiting roller 16 can deform and fit the power chip body 1, thereby increasing the contact effect, increasing stability, and preventing it from causing damage to the power chip body 1.

[0035] Working principle: This embodiment provides a power chip with electromagnetic interference resistance. When in use, the base 3 limits the power chip body 1, and by twisting the upper cover 2, the bottom of the upper cover 2 is fitted with the upper part of the base 3. At this time, the locking block 10 at the bottom of the upper cover 2 will be inserted into the locking groove 8. Then, by pushing the upper cover 2 to move, the upper cover 2 drives the locking block 10 to move, so that the locking plate 9 blocks the extension of the locking block 10. When the upper cover 2 moves, it will also pull the connecting rod 7, so that the connecting rod 7 drives the slider 6 to move in the sliding groove 5, so that the locking block 10 cooperates with the locking plate 9 to pull and fix one end of the upper cover 2, and the slider 6 cooperates with the connecting rod 7 to pull the other end of the upper cover 2, so that the upper cover 2 and the base 3 are fixed, so that the upper cover 2 and the base 3 cover the power chip body 1 inside, so that the upper cover 2 and the base 3 provide anti-electromagnetic protection for the power chip body 1;

[0036] By sliding the upper cover 2 in the opposite direction, the upper cover 2 will be reset and twisted under the torsion of the connecting rod 7, so that the locking block 10 is pulled out of the locking groove 8. The connecting rod 7 is a "V"-shaped structure, so the middle part of the connecting rod 7 will provide space for the upper cover 2 to twist, thereby preventing the connecting rod 7 from being blocked by the base 3 and the upper cover 2, resulting in the upper cover 2 being unable to twist, thereby completing the opening of the upper cover 2.
