Referring to fig. 1 to 8, a wireless power supply interface 10 of a high voltage device provided in an embodiment of the present application includes a male connector 100 and a female connector 200 that are mutually adapted, and the female connector 200 may include a first hooking portion 220. The male connector 100 may include a male connector body 110 and a second hooking portion 120; the second hooking portion 120 is connected to the male connection body 110. The second hooking portion 120 is configured to form a connection between the male connector 100 and the female connector 200 by hooking the first hooking portion 220 of the female connector 200.

The second hooking portion 120 may be an extension portion 121 extending from the surface of the male connection body 110 out of the plane thereof. The extending portions 121 may be disposed on the surface of the male connection body 110 along a straight line, may be disposed on the surface of the male connection body 110 along a specific arc, and may be disposed on the surface of the male connection body 110 along two "splayed" lines (i.e., the first extending portion 1211 and the second extending portion 1212 shown in fig. 3) or other polygonal lines. The extension 121 may be flat, in which case the plane of the extension 121 may not be perpendicular to the plane of the male connection body 110, for example: an included angle of 45 degrees is formed between the two, a hanging groove 150 for accommodating the first hanging part 220 can be formed in the space between the extending part 121 corresponding to the included angle and the male connection body 110, and the hanging between the male connection member 100 and the female connection member 200 is formed under the condition that the first hanging part 220 is accommodated in the hanging groove 150; the extension 121 may be other than a flat plate, for example, a curved surface or a bent surface, and may be bent or curved in a direction toward the plane of the male connection body 110.

Based on the above description, the shape of the first hooking part 220 may be matched with the shape of the receiving space described above, and the female connector 200 may be in a rectangular parallelepiped shape as shown in fig. 2.

In the above implementation process, through the hanging connection between the second hanging connection portion 120 provided on the male connector 100 and the first hanging connection portion 220 provided on the female connector 200, the connection between the male connector 100 and the female connector 200 can be implemented, so that the process of connecting the male connector 100 and the female connector 200 by the user operation is simplified.

With continued reference to fig. 1-8, in some alternative embodiments, the second hooking portion 120 may include an extension 121 extending from a surface of the male connection body 110 out of a plane thereof. The extension parts 121 are distributed on the surface of the male connection body 110 along a non-straight line. The extending portion 121 and the male connection body 110 are formed with a hanging slot 150 having an opening facing parallel to a plane of the male connection body 110. The hanging slot 150 is configured to receive and hang from the first hanging portion 220.

As in the previous embodiments, the extensions 121 may be distributed along a specific arc on the surface of the male connection body 110, or may be distributed along two "splayed" lines or other fold lines on the surface of the male connection body 110. The extension 121 may be formed in a flat plate shape and may be provided obliquely on the surface of the male connection body 110, or may be formed in another curved surface or a curved surface, so as to form a receiving groove with the male connection body 110.

It should be noted that the extension portion 121 may be integrally formed with the male connection body 110, or may be connected to the male connection body 110 by screwing, welding, or the like after the connection body is manufactured.

In the above implementation process, in the case that the extension portion 121 may be linearly distributed on the surface of the male connection body 110, the limitation of the extension portion 121 on the movement of the first hooking portion 220 on the plane of the male connection body 110 is generally limited to only one direction. In the case that the extension portions 121 are distributed on the surface of the connection body along a non-straight line, the extension portions 121 can limit the movement of the first hooking portion 220 on the plane of the male connection body 110 in at least two directions, so as to improve the stability and reliability of the hooking between the male connection member 100 and the female connection member 200.

With continued reference to fig. 1-8, in some alternative embodiments, the female connector 200 further includes a female connector body 210. The first hooking portion 220 includes a sliding portion 221, and the sliding portion 221 is connected to the female connection body 210. The extension 121 may include a first extension 1211 and a second extension 1212. The first extension 1211 and the second extension 1212 are non-parallel distributed over the male connection body 110. The side wall of the first extension portion 1211 facing the second extension portion 1212 forms a first sliding groove with the surface of the first connecting body. The side wall of the second extension portion 1212 facing the first extension portion 1211 forms a second sliding groove with the surface body. The surfaces of the first sliding groove, the second sliding groove and the male connection body 110 form a limiting groove 122 for receiving and sliding the sliding portion 221.

The female connection body 210 may have a rectangular parallelepiped shape or other shapes. The sliding portion 221 may be a portion extending from the female connection body 210, and may have a shape matching the shape of the limiting groove 122.

The sliding portion 221 and the female connection body 210 may be integrally formed, or may be connected together by welding, clamping, screwing, or the like.

The first extension portion 1211 may be linearly distributed on the surface of the male connection body 110, and the second extension portion 1212 may be linearly distributed on the surface of the male connection body 110, and further, the first extension portion 1211 and the second extension portion 1212 may be implemented as "eight" shapes distributed on the surface of the male connection body 110. The portion of the male connection body 110 where the first and second sliding grooves communicate between the first and second sliding grooves may form a limit groove 122, and the limit groove 122 may be a dovetail groove or a T-shaped groove, and the limit groove 122 is used for sliding the sliding portion 221 therein.

Because the first extension portion 1211 and the second extension portion 1212 are arranged in an "eight" shape, one end of the limiting groove 122 is generally narrow and the other end is generally wide. Further, the shape of the sliding portion 221 may be a trapezoid shape matching the shape of the limit groove 122. In such a case, the sliding portion 221 generally enters the limiting groove 122 from the wider end thereof, and the sliding portion 221 gradually enters the limiting groove 122 through sliding, and finally, is usually limited by the narrower end of the limiting groove 122 to stop sliding, so as to achieve the hooking between the male connector 100 and the female connector 200.

In the above implementation process, the connection between the male connector 100 and the female connector 200 is achieved by the limiting groove 122 formed between the first extension portion 1211 and the second extension portion 1212 which are not parallel to each other and the male connector 110, and the sliding portion 221 of the female connector 200 slides therein until being limited to stop sliding, so that the stability and reliability of the coupling between the male connector 100 and the female connector 200 are further improved.

With continued reference to fig. 1-8, in some alternative embodiments, the extension 121 may further include a third extension 1213. The limiting groove 122 has a wide end and a narrow end. The width of the narrow end is smaller than the width of the wide end. The third extension 1213 is located at a position toward which the narrow end is oriented, and restricts the sliding portion 221 from sliding out of the narrow end.

The third extension 1213 may be as described in the previous embodiment, which can form a third slide groove similar to the first slide groove and the second slide groove with the surface of the male connection body 110. The third extension portion 1213 may also be flat and vertically disposed on the male connection body 110, i.e. the sliding groove 250 is not formed between the third extension portion and the male connection body 110.

The third extension portion 1213 is generally used to limit the sliding portion 221 from sliding out of the narrow end in the case where the narrow end further defines the sliding portion 221 to slide out of the narrow end, particularly, the width of the sliding portion 221 of the female connector 200 is smaller than the width of the narrow end of the limiting groove 122.

Based on the above description, it will be understood by those skilled in the art that both ends of the third extension portion 1213 may be connected to the first extension portion 1211 and the second extension portion 1212, or may be connected to only one of the first extension portion 1211 and the second extension portion 1212, or may not be connected to the first extension portion 1211 or the second extension portion 1212, respectively. The distance between the third extension portion 1213 and the first extension portion 1211, and the distance between the third extension portion 1213 and the second extension portion 1212 can be determined by those skilled in the art according to the actual requirements.

In the above implementation process, the third extension portion 1213 is disposed at the position towards which the narrow end of the limiting slot 122 faces, so as to further limit the sliding portion 221 of the female connector 200 from sliding out from the narrow end, especially when the width of the sliding portion 221 is smaller than that of the narrow end of the limiting slot 122, so that the sliding portion 221 cannot be limited to slide out from the narrow end by the limiting slot 122, the sliding portion 221 can still be limited by the third extension portion 1213, and further, the stability and reliability of the coupling between the male connector 100 and the female connector 200 are further improved.

With continued reference to fig. 1-8, in some alternative embodiments, the female connector body 210 may be provided with a clamping hole 230. The male connector 100 may further include a clip 130 and an elastic member. One end of the elastic member is connected to the male connection body 110, and the other end is connected to one end of the clamping member 130, and is configured to provide a force from the male connection body 110 to the female connection member 200 to the elastic member. The other end of the clamping member 130 gradually decreases in circumference along the length direction thereof in a direction away from the elastic member, and is configured to be abutted against the surface of the female connector 200 under the action of the elastic member and slid from the surface of the female connector 200, and then abutted into the clamping hole 230 by the elastic member, so as to realize the clamping between the clamping member 130 and the clamping hole 230 when the first and second hanging portions 220 and 120 are hung.

The male connection body 110 may be provided with a blind hole for accommodating the elastic member and the clamping member 130, wherein one end of the elastic member is connected to the bottom of the blind hole, and the other end of the elastic member is connected to one end of the clamping member 130. The elastic member may be a spring, and in a natural state of the spring, one end of the clamping member 130 connected to the spring may be located in the blind hole, and the other end is located outside the blind hole. The engaging member 130 may be circular, square, or any other shape perpendicular to its length. The end of the clamping member 130 exposed outside the blind hole may be tapered, spherical or hemispherical, for example: a wave bead screw.

During the process of hooking the male connector 100 to the female connector 200, the end of the locking member 130 exposed outside the blind hole is usually abutted against the edge of the female connector 200 first, but gradually moves into the blind hole and compresses the spring under the guiding action of the tapered or spherical end. When the male connector 100 and the female connector slide relatively to the alignment of the clamping member 130 and the clamping hole 230, the clamping member 130 will be pushed into the clamping hole 230 under the elastic force of the elastic member, so as to realize the clamping between the clamping member 130 and the clamping hole 230. The locking between the male connector 100 and the female connector 200 is achieved.

In the opposite process, by sliding the male connector 100 and the female connector relatively, the tapered or spherical end of the locking member 130 will generally abut against the opening edge of the locking hole 230 first, and with sliding the male connector 100 and the female connector relatively, the locking member 130 will generally slide out of the locking hole 230 under the guiding action of the tapered or spherical end, so as to release the locking between the male connector 100 and the female connector 200.

In the above implementation process, the elastic member of the male connector 100 is matched with the hole of the clamping member 130 of the female connector 200 and the elastic member of the clamping member 130, so that the locking of the male connector 100 and the female connector 200 in the hanging state is realized, and the stability and reliability of connection are further improved. In addition, the end of the locking member 130 is shaped like a cone or a sphere, and the locking and unlocking of the male connector 100 and the female connector 200 are automatically performed by the guiding of the end surface thereof, further simplifying the operation of the male connector 100 by the user or the operator.

With continued reference to fig. 1-8, in some alternative embodiments, the female connector body 210 is further provided with a chute 250. One end of the sliding groove 250 communicates with the clamping hole 230, and the other end penetrates the outer surface of the female connection body 210. The sliding groove 250 has a depth smaller than that of the clamping hole 230, and is configured to receive the clamping member 130 during the sliding process of the sliding portion 221 in the limiting groove 122, and for the clamping member 130 to slide therein until the clamping member 130 is received by the clamping hole 230.

In the above implementation process, the sliding groove 250 receives the clamping piece 130, and the clamping piece 130 slides in the sliding groove 250, so as to guide the clamping piece 130. Furthermore, in the process of hooking the male connector 100 and the female connector 200, the guiding function is also achieved, so that the user can more accurately operate the male connector and the female connector to perform hooking.

With continued reference to fig. 1-8, in some alternative embodiments, the female connector 200 is provided with a first transformer 240 and is used to connect to an electrical signal metering device. The connection is provided with a second mutual inductance 140 and is used for connecting the communication device. In the case where the second hooking portion 120 is hooked to the first hooking portion 220, a distance between the first and second mutual inductance coils 240 and 140 is less than a mutual inductance range. Wherein the mutual inductance range is related to the intrinsic properties of the first mutual inductance 240 and the intrinsic properties of the second mutual inductance 140. The second mutual inductance coil 140 is configured to deliver electric power to the electric signal metering device by coupling with the first mutual inductance coil 240 in the case where the second hooking portion 120 is hooked.

The electrical signal measuring device may be a voltage measuring device, a current measuring device, or the like.

Taking a high-voltage metering device as an example, with the development of smart grid technology, an integrated high-voltage metering mode has become a trend. An integrated high-voltage metering device (high-voltage energy meter or high-voltage metering device for short) is an instrument for measuring active electric energy and reactive electric energy by directly connecting a 6 kV-35 kV power line. In order to obtain measurement data of the high-voltage metering device and remotely maintain the high-voltage metering device, a public network communication function is required to be provided for the high-voltage metering device, and since the installation position of the high-voltage metering device is generally 7 to 12 meters away from the ground, and a mobile communication network is used for public network communication, maintenance operations such as replacing a SIM card and the like are sometimes required, and a high-voltage loop is inconvenient to carry out live operation, a mode of combining the high-voltage metering device with the public network communication device is generally adopted.

The public network communication device of the high-voltage metering device is an important component of a high-voltage metering acquisition system, performs data interaction with the high-voltage metering device in a wired or wireless mode, acquires electricity consumption data of the high-voltage metering device, and is accessed into a master station of the acquisition system in a wireless public network (2G/3G/4G) communication mode.

The most commonly used high-voltage metering and collecting mode at present is that a micropower wireless (such as GFSK/LoRa and the like) communication module or communication unit is arranged in the high-voltage metering device, data of the high-voltage metering device are sent to a nearby collecting terminal device, and the collecting terminal is accessed to a collecting system through a wireless public network communication mode (2G/3G/4G).
