Abstract

The electric shock prevention waterproof socket mainly utilizes two principles: the first is primarily the lock and key principle. The socket is compared to the lock and the plug is compared to the key, only the matching plug (key) can be inserted and causes a displacement or deflection of the entity (core) in the socket (lock). The second is mainly to make two entities (core components) in the socket contact and separate by external force, thereby causing power on and off. The core component in the socket is displaced or rotated to contact or separate the contacts of the power supply, so that the power supply of the plug is switched on or off. The two principles are organically combined to form a set of waterproof and electric shock-proof socket. The invention solves the problem of electric shock caused by the fact that children use foreign matters to randomly insert the socket or adults do not pay attention to contact with the electrified socket or plug, and also solves the problem of short circuit caused by water splashing to the socket when the plug is not detached from the socket.

Description

Electric shock-proof water-proof socket

Technical Field

The invention is suitable for indoor and outdoor electric shock and water prevention functions of the socket.

Background

In life, people often plug and unplug the plug, and sometimes the hands do not touch the live plug in a plug-in state (under the condition that the live wire and the zero wire are connected), so that electric shock is caused. Sometimes water is inadvertently sprayed onto the socket causing electrical leakage to occur. The socket mainly adopts the principle of a lock, and then contacts and separates a power supply contact through rotation or displacement, thereby realizing the electric shock prevention and waterproof functions. The socket has a certain closed space, and can be switched on only by rotating or displacing, so that the socket has a certain waterproof function.

Disclosure of Invention

The invention mainly uses two principles, the first is the principle of the lock, and the second is the principle of different positions contacting different positions, to form a set of electric shock prevention function. When the plug is inserted into the socket, the plug is equivalent to a key, and only if the plug is of a certain thickness or shape, the round-head marble in the socket reaches a fixed position, the round-head marble and the flat-head marble in the socket are positioned at the edge of a key entity in the socket, namely the round-head marble is just positioned in the entity, the flat-head marble is just positioned outside the entity, and the rotation or displacement function (with the function of identifying the plug) of the entity in the socket can be realized just without hindering the rotation or displacement of the entity in the socket, so that the power supply can be further contacted, and the power supply can be switched on. When the plug is pulled out, the key position of the socket is reset under the action of the spring, the contacts are reset mutually and separated from the power supply contact, the power supply is disconnected, the socket is in a non-electricity state at the moment, the round head marble and the flat head marble are reset under the action of the spring through the entity round hole track to clamp the entity in the socket, when the outside unmatched entity is inserted, the flat head marble displacement positions of the round head marble are not aligned, the movement of the key entity in the socket is clamped, and the anti-electric-shock function is realized through the functions. The socket has a certain closed space, as shown in the figure, an entity B is the closed space, and only the socket hole at the plug insertion position is opened. And the power supply can be switched on only by rotating or displacing, so that the waterproof function is realized to a certain extent.

Detailed Description

Drawings

Fig. 1, 2, 3 and 4 constitute a socket configuration. Fig. 2, 3 and 5 constitute a socket configuration.

FIG. 1 illustrates

FIG. 1 is a visual illustration of a plug inserted into a socket and not rotated and a plug inserted into the socket and rotated, wherein the plug inserted into the socket and not rotated is the first state in FIG. 1, when the plug is inserted into the socket and rotated, a limit baffle is arranged in the plug to block the plug when the plug reaches the position in the figure, the plug is changed from the first state to the second state when the plug is not rotated any more, when the second state is changed into the first state, the plug only needs to be pulled out, and the return process only needs to retract the internal spring to realize the function. When in the first state, a baffle plate also blocks the first state, so that the first state is kept. In the figure, the circle inside the surface of the solid F is smaller than that of the solid B, so that the solid B is wrapped in the solid F and cannot come out. B is internally provided with a fixed groove which is fixed inside and can not generate displacement when rotating.

FIG. 2 illustrates

Fig. 2 is an explanatory diagram when the plug is a solid body (without a groove or a round hole), when the plug is a solid body, when the plug is inserted, the round-head marble is pushed to displace, the round-head marble pushes the flat-head marble to displace, the displacement distance and the plug thickness have a certain correlation, and the round-head marble and the flat-head marble can be just positioned inside and outside the plug B only if the plug is just thick, which is the same as the principle of the lock. Therefore, the purpose of accurately identifying the plug is achieved, and therefore, foreign objects such as steel wires, screw drivers and the like can be inserted without displacement or rotation.

FIG. 3 illustrates

Fig. 3 is a state illustration diagram when a plug entity is provided with a groove or a circle, more than two pairs of round-head marbles and flat-head marbles can be designed, one round-head marble is placed on the corresponding entity when the plug is completely inserted, and the other round-head marble is placed on the corresponding groove or round hole when the plug is completely inserted, so that the purpose of identifying the thickness of the plug entity can be achieved, and the purpose of identifying the plug circle or the groove can also be achieved. When plugs with the same circle or groove but different thicknesses are inserted, the displacement generated by the round-head marble and the flat-head marble which correspond to the round-head marble with the same thickness originally has deviation from the original displacement, so that the entity B can not rotate or can not generate displacement, and the purpose of accurately identifying the plugs is achieved. When the plug A is completely inserted and is displaced or rotated, the entity B is displaced, so that the tail part of the round-head marble in the round hole of the entity B is changed into the tail part of the round-head marble in the entity position of the entity B (no round hole).

FIG. 4 illustrates

Fig. 4 shows the process of generating spin induction and power contact and disengagement by the internal entity B of the socket.

In the figure, the entity D is composed of two round balls, a spring and a fixed outer sleeve, and the diameter of the outer sleeve is smaller than the maximum diameter of the round balls, so that the outer sleeve just wraps the two round balls and the round balls cannot come out.

In the figure, the entity E is composed of a spring, a concave entity and a fixed track outer sleeve, and the outer sleeve is wrapped on the entity E so that the entity E cannot pop up.

FIG. 4 shows that when the plug A is inserted into the solid B, the round-head marble and the flat-head marble are displaced in the fixed track, the gap between the round-head marble and the flat-head marble just reaches the edge of the circle of the solid B (the round-head marble is in the solid B, and the flat-head marble is outside the solid B), so that the solid B can identify the thickness of the plug A, only the thickness of the plug A just can cause the gap between the round-head marble and the flat-head marble just reaches the edge of the circle of the solid B (the round-head marble is in the solid B, and the flat-head marble is outside the solid B), the whole solid B can rotate, when the solid B rotates to a fixed position (the baffle blocks the rotation of the solid B), the baffle stops, the built-in spring is tensioned, when the socket A is completely inserted into the solid B, the socket A touches the first round ball (ball 1) of, through force transmission, a first round ball (ball 1) is transmitted to the spring, the spring is transmitted to another round ball (ball 2), the spring in the entity D is compressed, the ball 2 in the entity D is completely extruded on the two balls and the outer sleeve of the spring, and the outer sleeve is smaller than the diameter of the balls, so that the ball can only be extruded on the edge of the outer sleeve and cannot be ejected. When the entity B rotates to the entity E, the ball 2 is in close contact with the entity E due to the action of force, the entity D is in close contact with the entity E at the moment, the contact force of the ball 2 and the entity E in the entity D is larger than the tension of the built-in spring, and therefore the rotation displacement cannot occur again. At this time, the body B also has related spring leaves to tightly wrap the plug, so that the plug is not easy to eject. When the plug is pulled out of the entity B, the plug does not extrude the entity D, the built-in spring of the entity D pulls the two balls back, so that the balls 2 in the entity D lose extrusion force, and the tension of the built-in spring is greater than the interaction force of the balls 2 in the entity D and the entity E, so that the built-in spring reversely returns under the action force of the built-in spring. And restoring the previous state. At this time, the jack in the socket is in a power-off state because it is separated from the contact.

FIG. 5 illustrates

Fig. 5 shows the process of the displacement of the solid body C inside the socket to make and break contact with the power supply contact.

In fig. 5, the entity C is two independent metal grooves matched with the plug, and the middle connection is non-metal.

Figure 5 illustrates that when the plug is inserted into the socket, the rounded and flat head pins in the socket identify the correct socket (only the appropriate thickness or recess of the socket will cause the rounded and flat head pins to displace properly and will move the body C), thereby pushing the body C into displacement so that the body C contacts the power contacts, thereby causing the plug to be powered (with the bottom spring compressed). When a plug is inserted into the solid C, the corresponding spring piece in the solid B is contacted with the plug, so that the plug is not easy to eject. When the plug is pulled out, the solid C is popped up under the action of the spring at the bottom of the solid C, the solid C is separated from the power contact, and the socket is restored to the original state at the moment. The jack has no power.
