[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 An anti-static housing for a power adapter includes: an adapter housing 1, the outer wall of the adapter housing 1 having a friction texture 2, an anti-breakage connector 3 fixedly connected to the outer wall of the adapter housing 1, a power cord 4 connected to the outer wall of the anti-breakage connector 3, an elevation line 5 on the inner wall of the adapter housing 1, a round connector 6 connected to the inner wall of the adapter housing 1, a circuit board 7 placed in the inner cavity of the adapter housing 1, a threaded head 8 threadedly connected to the inner wall of the circuit board 7, a connecting shell 9 fixedly connected to the inner wall of the adapter housing 1, a top cover 10 placed on the top of the adapter housing 1, screws 11 connected to the outer wall of the top cover 10, a display screen 12 on the outer wall of the top cover 10, a conductive strip 13 on the inner wall of the top cover 10, a grounding strip 14 on the bottom of the adapter housing 1, and a fixing strip 15 connected to the bottom of the adapter housing 1.

[0023] The inner walls of the adapter housing 1 and the top cover 10 are provided with a shielding layer 16, which is made of conductive plastic. The shielding layer 16 is made of ordinary plastic with the addition of conductive fillers such as carbon black and metal powder, so that the shielding layer 16 has the lightweight of plastic and good electrostatic shielding ability. Thus, when the adapter housing 1 and the top cover 10 of the device enclose electrical components, the shielding layer 16 is used to increase the electrostatic shielding ability.

[0024] There are two anti-breakage connectors 3 and two power cords 4, and the two anti-breakage connectors 3 and two power cords 4 are symmetrically arranged on both sides of the adapter housing 1. Through the two anti-breakage connectors 3 and two power cords 4 on the device, the two power cords 4 on the device are connected to the charging head and the power transmission head at the two ends away from the device, so that the anti-breakage connectors 3 on the device avoid the problem of wire bending at the connection between the power cord 4 and the adapter housing 1.

[0025] Among them, there are several friction patterns 2, and several friction patterns 2 are arranged on the front and back sides of the device. Through the several friction patterns 2 on the device, the friction patterns 2 on the smooth surfaces of the front and back sides of the device increase the degree of friction, thereby avoiding the situation of not being easy to grip when picking up the device.

[0026] The inner wall of the connecting shell 9 is provided with an internal thread, and the outer wall of the screw 11 is provided with an external thread. By connecting the shell 9 and the screw 11 on the device, when the top cover 10 on the device is placed on the top of the adapter shell 1, the screw 11 is used to make a spiral connection from top to bottom, thereby closing the upper and lower structures of the device, and thus completing the inner and outer closure of the entire device.

[0027] The conductive strip 13 is made of aluminum and is ring-shaped on the surface of the top cover 10. By using aluminum as the conductive strip, the conductive strip 13 can effectively conduct static charge to the ground by utilizing the conductivity of the material on the surface of the top cover 10.

[0028] The bottom of the conductive strip 13 is connected to a grounding strip 14, and the grounding strip 14 extends to the bottom of the device. Since the bottom of the conductive strip 13 on the device is connected to the grounding strip 14, the conductive strip 13 and the grounding strip 14 on the device are made of the same material and use the same conductivity to guide the static electricity on the surface of the device to the bottom of the device. Thus, when the bottom of the device is in contact with the ground, the grounding strip 14 guides the static electricity to the ground.

[0029] The fixing strip 15 is made of natural resin, and the inner wall of the fixing strip 15 has an inner groove. Due to the use of natural resin material, the fixing strip 15 contacts the ground at the bottom of the adapter housing 1. The grounding strip 14 is loaded in the inner groove of the fixing strip 15, so that the grounding strip 14 is flush with the fixing strip 15 in the inner cavity of the fixing strip 15, and thus the grounding strip 14 and the fixing strip 15 are in contact with the ground at the same time.

[0030] The working principle is as follows: First, by setting up structures such as the adapter shell 1, top cover 10, and shielding layer 16, the adapter shell 1 and top cover 10 on the device overlap vertically, wrapping the internal electrical components. The adapter shell 1 and top cover 10, together with the shielding layer 16, increase the electrostatic shielding capability on the outermost side of the device, ensuring that the device enhances its electrostatic protection. Then, by setting up structures such as the top cover 10, conductive strip 13, fixing strip 15, and grounding strip 14, the conductive strip 13 on the device receives sensitive static electricity on the surface of the top cover 10 and guides the static electricity to the grounding strip 14. The grounding strip 14 contacts the ground, thereby conducting the static charge to the ground, thus protecting the internal circuit from electrostatic interference.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
