[0033] The DC power socket in this technical solution is a common power socket currently available on the market. Its welding method and usage method are common knowledge in this field, so they are not described in detail in this technical solution. The positive copper core 4 in this technical solution adopts an integrated riveted structure with clips, which can withstand large currents and improve stability in use. The arc-shaped protective sheet 22 arranged between the socket 2 and the shielding sheet 16 can be designed to ensure strength while reducing the risk of cracking due to glue extrusion after riveting. The protruding welding points of the detection static sheet 11 and the negative spring sheet 12 are arc-shaped chamfered settings, which can ensure sufficient welding while facilitating assembly, saving assembly time and increasing work efficiency.

[0034] like Figure 4 and Fig. 9 As shown, the shielding sheet 16 has first inner openings 17 symmetrically opened at the top and bottom, and a first inner sheet 18 is fixedly connected to the inner wall of the rear side of the first inner opening 17. The first inner sheet 18 is inclined, and the front side wall of the first inner sheet 18 contacts the base 1.

[0035] The first inner buckle piece 18 of the shielding sheet 16 can be stably stuck on the base 1, so that the shielding sheet 16 will not be separated from the base 1 during use, and plays a role in protecting the base 1 and shielding at the same time. The shielding sheet 16 is made of metal.

[0036] like Figure 3 and Figure 7 As shown, rectangular grooves 14 are respectively opened on the top and bottom of the base 1, auxiliary grooves 15 are respectively opened on the top and bottom near the front side of the base 1, and second inner buckle openings 19 are respectively opened on the top and bottom of the shell 13. The second inner buckle plate 20 is fixedly connected to the inner wall of the rear side of the second inner buckle opening 19, and the second inner buckle plate 20 is inclined and extends into the rectangular groove 14.

[0037] The second inner buckle piece 20 on the outer shell 13 can stably clamp the outer shell 13 on the outer wall of the base 1, which can play a protective role and improve the aesthetics at the same time.

[0038] Among them, the inner walls of the upper rectangular opening 23 and the lower rectangular opening 24 are respectively tapered near the front side, so that the front openings of the upper rectangular opening 23 and the lower rectangular opening 24 are relatively large and are inclined. In this way, when the protruding side of the detection static plate 11 and the negative electrode spring sheet 12 pokes into the relatively large openings on the front side of the upper rectangular opening 23 and the lower rectangular opening 24, they will gradually slide out of the base 1 through the inclined surface to avoid getting stuck, thereby effectively improving the speed of installation.

[0039] In addition, protrusions 21 are respectively provided at the top and bottom of the inner cavity of the outer shell 13 near the right side, and the protrusions 21 extend into the first inner buckle opening 17 and contact the first inner buckle sheet 18. The protrusions 21 can limit the position of the first inner buckle sheet 18 on the right side, so that the first inner buckle sheet 18 cannot be tilted upward before the outer shell 13 is removed, thereby effectively reinforcing the stability of the assembly of the shielding sheet 16.

[0040] Among them, the detection static sheet 11 and the negative electrode spring sheet 12 are respectively extended to one side outside the base 1 and are arranged in an arc shape, so that they can easily pass through the upper rectangular opening 23 and the lower rectangular opening 24. Even if the protruding side of the detection static sheet 11 and the negative electrode spring sheet 12 touch the upper rectangular opening 23 and the lower rectangular opening 24, they will not get stuck.

[0041] Working principle: The positive copper core 4, the detection static sheet 11 and the negative spring sheet 12 of the technical solution are commonly processed parts in the prior art. Their welding and use methods are common knowledge in this field, so they are not described in detail in this technical solution. Next, just the installation method is upward. First, the detection static sheet 11 is placed between the two first placement grooves 9 through the assembly opening 5, and then the negative spring sheet 12 is placed between the two second placement grooves 10 through the assembly opening 5. At this time, the protruding sides of the detection static sheet 11 and the negative spring sheet 12 are respectively located on the outside of the base 1. Next, the upper rectangular opening 2 on the rear cover 7 is opened. 3 corresponds to the detection static sheet 11, the lower rectangular opening 24 corresponds to the negative spring sheet 12, and the detection static sheet 11 and the negative spring sheet 12 are respectively inserted into the upper rectangular opening 23 and the socket 2, through the upper rectangular opening 23 and the lower rectangular opening 24 inner wall is set in a conical shape, and the detection static sheet 11 and the negative spring sheet 12 protruding side is set in an arc shape, so the detection static sheet 11 and the negative spring sheet 12 protruding side can easily pass through, will not be blocked or stuck in the upper rectangular opening 23 and the lower rectangular opening 24, then the rear cover 7 is placed in the positioning hole 6 and pressed, so that the positioning hole 6 on the rear cover 7 The tilting block 8 enters the positioning hole 6, so that the back cover 7 can be stuck on the rear side wall of the base 1 without loosening. Next, the shielding sheet 16 is put on the front wall of the base 1 and pressed hard, so that the arc-shaped protective sheet 22 enters the base 1. At the same time, the shielding sheet 16 is completely put on the base 1, so that the four first inner buckle sheets 18 are stuck on the base 1, so that the shielding sheet 16 can be fixed on the base 1. The positive copper core 4 is assembled in the installation opening 3 by mechanical pressing, and the conical clamping thorn 25 is stuck in the installation opening 3, so that the positive copper core 4 is stably fixed in the installation opening 3. At the same time, the outer shell 13 is finally put on the front side of the base 1 and pushed backward so that it is in the two auxiliary grooves 15 on the outer shell 13, and the outer shell 13 is continued to be pressed so that the second inner buckle sheet 20 enters the rectangular groove 14, and the second inner buckle sheet 20 will press against the partition between the rectangular groove 14 and the auxiliary groove 15, so that the outer shell 13 is stably installed on the base 1. In addition, when the second inner buckle sheet 20 enters the rectangular groove 14, the protrusion 21 will also enter the first inner buckle opening 17 and contact the first inner buckle sheet 18, which can further prevent the shielding sheet 16 from loosening and improve the stability of use.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
