Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sockets, and in particular to an electrical hidden danger sensing socket. Background Art
[0002] Some existing intelligent detection sockets can detect residual current and cut off power supply, but they cannot monitor dangerous hidden dangers such as incorrect wiring sequence of neutral wire and live wire, abnormal power supply voltage, missing and faulty ground wire, etc., which require a lot of data collection and analysis of the power supply system to discover. These judgments must first determine whether the wiring sequence of the neutral wire and the live wire is correct. When making this judgment, the analysis circuit requires an external potential reference point formed by human touch. By analyzing the voltage of this point with the neutral wire and the voltage of the live wire, it is determined whether the connected line sequence is correct. For safety requirements, this reference point must be isolated by a current limiting resistor and a safety capacitor to form an absolutely safe touch button. In addition, the control and setting of the socket circuit requires at least one button. For a socket with intelligent functions, too many control buttons will increase the difficulty of use and occupy the limited available space on the socket panel. Summary of the invention

[0033] The present invention provides a socket for sensing hidden dangers in electricity use.
[0034] In the embodiment of the present invention, Figures 1 to 3 As shown, the electrical potential hazard sensing socket includes:
[0035] The socket cover 1 is provided with a mounting hole 11;
[0036] A control circuit board 2 is installed on one side of the socket cover 1, and a feeding point 21 and a micro switch 22 are provided on the surface of the control circuit board 2 facing the socket cover 1, and the feeding point 21 and the micro switch 22 are arranged at intervals; and
[0037] The touch key 3 comprises a conductive key cap 31, an insulating elastic member 32 and a conductive spring 33. The insulating elastic member 32 is located between the socket cover 1 and the control circuit board 2. The conductive key cap 31 passes through the mounting hole 11 and is mounted on the insulating elastic member 32. The insulating elastic member 32 is provided with a spring hole 3223. The conductive spring 33 passes through the spring hole 3223 to electrically connect the conductive key cap with the feeding point 21. The insulating elastic member is provided with a protrusion 3221 at a position corresponding to the micro switch 22.
[0038] When the conductive key cap 31 is pressed, the protrusion 3221 presses the micro switch 22 , and the conductive spring 33 provides the conductive key cap 31 with a rebound force after the pressing is released.
[0039] The technical solution of the present invention is to set a conductive key cap and an insulating elastic member on the socket cover so that the user can trigger the touch key when only touching the conductive key cap, and the induction signal is transmitted to the internal circuit of the control circuit board through the conductive key cap, the conductive spring and the feeding point to provide a potential reference point; when the conductive key cap is pressed, not only the touch key switch is triggered, but also the micro switch set on the control circuit board as a mechanical switch is triggered, so that one key can control the signal input of two switch circuits at the same time, and a composite function key of a touch key that meets the electrical safety distance requirements and a micro switch for providing control and setting functions is realized by one key, which reduces the number of keys on the socket cover, simplifies the structure, saves materials, and makes the control of the electrical hazard perception socket more intelligent, more convenient to operate, and improves the user's experience. Among them, the use of insulating elastic members increases the electrical safety distance of the micro switch and the touch key; the conductive spring not only conducts the feeding point and the conductive key cap on the control circuit board, but also provides the conductive key cap with a rebound force for resetting, which has a simple structure and reduces costs.
[0040] Among them, in this embodiment, the micro switch 22 is made of metal material, and the insulating elastic member 32 is made of insulating material to avoid the connection between the two switch control circuits of the touch button 3 and the micro switch 22, ensuring that the two switches do not interfere with each other and work normally.
[0041] The touch button 3 contacts the human body through the conductive button cap 31 to provide an external potential reference point. The micro switch 22 serves as a control button to control the on or off of the power hazard sensing socket for detection, or to turn off the alarm issued by the power hazard sensing socket.
[0042] The following combination Figures 4 to 5In this embodiment, the insulating elastic member 32 includes a fixing block 321 fixed to the socket cover 1, an isolation plate 322 for mounting the conductive key cap 31 and provided with the protrusion 3221, and an elastic connecting arm 323 connecting the fixing block 321 and the isolation plate 322. Thus, the isolation plate 322 is elastically connected to the fixing block 321 through the elastic connecting arm 323 to move between the control circuit board 2 and the socket cover 1, so that the protrusion 3221 has a first position placed above the micro switch 22 and a second position pressed against the micro switch 22.
[0043] It can be understood that the insulating elastic member 32 is arranged between the control circuit board 2 and the socket cover 1, and the socket cover 1 has a first side facing the control circuit board 2 and a second side facing away from the first side, the second side is the outer surface of the electrical hazard sensing socket, and the second side is provided with a jack for plug insertion, the insulating elastic member 32 is arranged on the first side, and the conductive key cap 31 passes through the mounting hole 11 from the first side to the second side for user operation. In this embodiment, the conductive key cap 31 is arranged on one side of the isolation plate 322 facing the socket shell, and the protrusion 3221 is arranged away from the conductive key cap 31 and is arranged on the other side of the isolation plate 322 facing the control circuit board 2, so that when the conductive key cap 31 is pressed, the protrusion 3221 presses against the micro switch 22 of the control circuit board 2.
[0044] Further, in this embodiment, specific reference is made to Figure 3 , the elastic connecting arm 323 is arranged in an arc shape, and the arc convex surface of the elastic connecting arm 323 faces the socket cover 1. In this way, it is simply realized that when the conductive key cap 31 is pressed, the conductive spring 33 gives the conductive key cap 31 a rebound force to reset, and the elastic connecting arm 323 gives the isolation plate 322 a rebound force, so that the protrusion 3221 on the isolation plate 322 returns from the second position to the first position. Without loss of generality, in other embodiments, the elastic connecting arm 323 can also be arranged in a wave shape so that it has a deformation elastic force.
[0045] Furthermore, in this embodiment, the conductive key cap 31 can be detachably mounted on the insulating elastic member 32 , so that it is convenient for maintenance, disassembly, and material recycling.
[0046] In this embodiment, the conductive button cap 31 is clamped between the insulating elastic member and the mounting hole 11 of the socket cover 1. Figure 5The conductive key cap 31 has an opening 311, and a stop convex ring 312 is provided at the end of the opening 311 of the conductive key cap 31. The isolation plate 322 is provided with a mounting post 3222 at a position corresponding to the mounting hole 11. The conductive key cap 31 is sleeved on the mounting post 3222, and the end surface of the opening 311 is in contact with the isolation plate 322. The stop convex ring 312 is clamped on the edge of the mounting hole 11. Thus, the installation of the conductive key cap 31 is simply realized, and no other parts are required to fix the conductive key cap 31, saving materials. Furthermore, one end of the mounting post 3222 connected to the conductive key cap 31 is arranged in an arc shape to avoid noise and wear caused by friction between the mounting post 3222 and the conductive key cap 31 when the conductive key cap 31 is pressed, and has a better sense of use.
[0047] Furthermore, in the present embodiment, the mounting column 3222 is provided with a spring hole 3223 arranged along the axial direction, and the spring hole 3223 is provided with the conductive spring 33 connecting the conductive button cap 31 and the feeding point 21, and the conductive spring is limited in the spring hole 3223, one end of which abuts against the conductive button cap 31, and the other end abuts against the feeding point 21. In this way, the conductive spring 33 is accommodated and fixed by the structural arrangement of the mounting column 3222, which facilitates the connection between the conductive button cap 31 and the feeding point 21 of the control circuit board 2. The electric spring not only realizes the connection between the conductive button cap 31 and the control circuit board 2, but also provides a rebound force to the conductive button cap 31 when it is pressed, which facilitates the resetting of the conductive button cap 31 and optimizes the product structure.
[0048] Furthermore, in this embodiment, the insulating elastic member 32 is welded and fixed to the socket cover 1, the fixing block 321 is provided with a fixing hole 3211 for welding and fixing, the insulating elastic member 32 is made of plastic material, and the fixing block 321 is fixed to the first side of the socket cover 1 by welding and hot melting, so that the insulating elastic member 32 is firmly installed on the socket cover 1, and the reliability of the switch structure of the electrical hazard sensing socket is improved. It can be understood that in other embodiments, the insulating elastic member 32 can also be configured to be fixed with the socket cover 1 by clamping, so that the insulating elastic member 32 can be stably installed.
[0049] Furthermore, in this embodiment, the conductive button cap 31 is arranged at one end of the isolation plate 322 away from the elastic connecting arm 323, and the protrusion 3221 is arranged at one end of the sliding plate close to the elastic connecting arm 323, so that it is easier to push the protrusion onto the micro switch 22 by pressing the conductive button cap 31, and the isolation plate 322 is provided with a limiting rib 3224 for limiting the movement of the conductive button cap 31, and the limiting rib is arranged around the mounting column on the isolation plate.
[0050] In this embodiment, the conductive key cap 31 is set to be cylindrical, the mounting post is set at one end of the isolation plate away from the elastic connecting arm, the limiting rib 3224 is adapted to be set to be semi-annular with the conductive key cap 31, and the limiting rib 3224 is set to semi-surround the conductive key cap 31, which ensures the stability of the conductive key cap 31 and reduces the preparation materials. However, the present design is not limited to this. In other embodiments, the limiting rib 3224 can also be in a circular shape, surrounded by the mounting post 3222, forming an annular mounting groove adapted to install the conductive key cap 31, so that the installation of the conductive key cap 31 is more stable.
[0051] Furthermore, in this embodiment, a reinforcing rib 3225 is provided at one end of the isolation plate 322 connected to the elastic connecting arm 323. The reinforcing rib 3225 is provided on one side of the isolation plate 322 where the limiting rib 3224 is provided, and is connected to the limiting rib 3224. A plurality of reinforcing ribs 3225 are provided, and extend from one end of the isolation plate 322 connected to the elastic connecting arm 323 to the limiting rib 3224 to increase the structural strength of the insulating elastic member 32.
[0052] In this embodiment, by providing the reinforcing ribs 3225 and the limiting ribs 3224 on the isolation plate 322, the electrical clearance and creepage distance are increased, and the electrical safety between the touch button 3 and the micro switch 22 is improved. The reinforcing ribs 3225, the limiting ribs 3224, and the mounting posts 3222 are all provided on one side of the isolation plate 322, away from the protrusions 3221, so that only the protrusions 3221 are provided on the side of the isolation plate 322 facing the control circuit board 2, so that the protrusions 3221 can better correspond to and abut against the micro switch 22.
[0053] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
