Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings of fig. 1 to 8. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in many ways other than those described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit of the invention, and therefore the invention is not limited to the specific embodiments disclosed below.
in order to better protect the jack 14, the jack 14 is arranged on the inner side of the socket side cover 7, and the upper end and the lower end of the jack 14 are respectively provided with a clamping groove 10 and a rectangular groove 11; the spring 3 is arranged on the clamping groove 10, one end of the spring 3 is fixedly arranged on the clamping groove 10, in order to enable the top column 2 to be better matched with the spring 3, the other end of the spring 3 is fixedly connected with the top column 2 through a cylindrical top cap arranged on the top column 2, so that the reset of the spring 3 is realized, and the purpose of locking the top column 2 and the plug pins of the plug 1 is achieved, and the top cap is cylindrical; one end of the supporting rod 5 is relatively rotatably arranged at the lower rear part of the top column 2, a notch is formed in the outer side of the rotating shaft, the top column 2 is reset under the elastic action of the spring 3, one side of the top column is matched with the notch, the supporting rod 5 is locked, foreign matters are prevented from being electrically shocked, and the safety coefficient is increased;
for example: when a foreign object (a finger, a key or the like) touches the jack 14, the support rod 5 is rigid, and the support rod 5 is locked by the top column 2 no matter how the foreign object is inserted, so that the possibility of electric shock of the foreign object is reduced;
one end of the elastic pressing piece 4 is embedded in the socket 9, and the other end of the elastic pressing piece is propped against one end of the supporting rod 5 and is in sliding contact with the supporting rod 5 for supporting and resetting the supporting rod 5, and in order to better lock the pin of the plug, the elastic pressing piece 4 drives the supporting rod 5 to tightly clamp the plug 1 under the driving of the rotating shaft through self elasticity;
before the contact on the travel switch 6 does not act, the socket 9 is in a power-on state, when the pin of the plug 1 enters the jack 14, the contact on the travel switch 6 acts, the socket 9 is powered off, when the pin completely enters the jack 14, the rectangular groove 11 avoids the contact on the travel switch 6, and the socket 9 is powered on again, so that the electric shock prevention function when the socket 9 is inserted by foreign matters is realized;
the inner sides of the two ends of the socket side cover 7 are provided with electric shock prevention devices 12, the lower ends of the left side surface and the right side surface of the socket 9 are symmetrically provided with the socket side cover 7, and in order to better protect the socket 9, the outer side of the socket side cover 7 is provided with a socket shell 8 to prevent electric leakage and electric shock;
the number of the jacks 14 is at least two, the number of the pins on the plug 1 corresponding to the jacks is two, and the lower ends of the pins are provided with a long groove 13 for switching on and off the travel switch 6;
in an alternative embodiment of this embodiment, as shown in fig. 7, the long groove 13 on the plug 1 is located at a distance of 2-3 mm from the pin to the root of the pin, the socket 9 is not powered during the insertion of the plug 1, and is powered until the plug is inserted soon, so as to directly avoid artificial contact and electric shock, and rounded corners are further provided on two sides of the long groove 13, so as to facilitate the action of the contact of the travel switch 6.
When the plug-in sheet which is contacted carelessly is inserted into the socket, the leakage distance of the common socket is large, when the common socket is half inserted, the plug is electrified, and the finger plug of a child or an adult directly contacts to get an electric shock; the long groove 13 of the plug is provided with the distance of the conducting electrode limit of 2-3 mm, so that a person can not contact the inserting sheet at all, and when the distance is larger, the inserting sheet can compress the travel switch to directly cut off the power supply, thereby effectively solving the safety problem of people;
the working principle of the invention is as follows:
because the support rod 5 is locked by the top post 2 on the spring 3 through the groove, the support rod 5 can not rotate left and right through the rotating shaft, at the moment, the support rod 5 is a rigid support rod, foreign matters can not be inserted into the support rod and get an electric shock, the socket 9 is in a power-on state before the travel switch 6 is not inserted, and the tail part of the pin, which is far away from the top end of the pin, of the plug 1 at two ends is provided with a long groove;
when the plug 1 is inserted into a small section, the round angle of the pin on the upper end of the plug 1 can extrude the top column 2, so that the compression spring 3 moves upwards, the supporting rod 5 can realize self-locking due to the fact that the pin extrudes the top column 2, the pin can be further inserted, along with the gradual insertion of the pin, the electric shock of the travel switch 6 on the lower end of the pin is compressed, so that the power failure of the socket 9 is realized, and the socket 9 is always in a power failure state before the travel switch 6 is not jacked;
when the distance between the pins is completely inserted into the jack 14 and is 2 to 3 millimeters, the upper ends of the pins are inserted to drive the supporting rod 5 to rotate upwards and prop against the elastic sheet 4 and be clamped in the groove at the upper end, then the locking of the pins on the plug 1 is realized through the elasticity of the elastic sheet 4 and the reaction force of the support column 2, the travel switch 6 is just bounced in the groove of the pin until the pins are completely inserted, and therefore the socket 9 is electrified;
when the plug 1 is pulled out, the support rod 5 at the upper end of the jack 14 is reset by itself due to the elasticity of the elastic sheet 4, and the support rod 5 is just locked by the downward reset of the spring 3 on the top column 2, and the two processes are not interfered with each other in tandem; the pins are exposed at the lower ends of the jacks 14, and because the distance between the pins and the conducting electrodes of the jacks 14 is 2-3 mm, the pins cannot be contacted by hands at all, and when the distance is longer, the pins compress the travel switch 6 to be directly powered off, so that the situation that the pins of the touch plug 1 are partially electrified when the plug 1 is inserted or removed is prevented;
in addition, the invention can prevent foreign matters from being inserted into the socket and touching the plug blade part structure to be electrically shocked when the plug is inserted or pulled out, and has the advantages of small volume, safety, reliability, convenient manufacture and easy popularization.
In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings or orientations or positional relationships conventionally placed when the products of the present invention are used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
