Description

A kind of recessed anti-shock socket

technical field

The utility model relates to a socket combination device, in particular to an inner concave electric shock-proof socket.

Background technique

In order to ensure that the plug does not loosen from the socket, the traditional socket is equipped with metal shrapnel inside the socket, which is inconvenient to insert and pull out the plug. When in use, it may lead to incomplete insertion or failure to pull out at one time. That is, only a part of the plug is in the jack, and at this time the plug is charged, and the metal part of the plug outside the jack will pose a threat to the life safety of the user. When not in use, the live metal part inside the jack will be exposed to the air, which will pose a threat to the life safety of children. Therefore, there is a need for a socket that can effectively ensure the safety of users.

Contents of the invention

The utility model provides a recessed electric shock-proof socket for solving the technical problem that the current socket is difficult to plug in and has potential safety hazards when it is used.

The utility model is realized by adopting the following technical scheme: a concave electric shock-proof socket, comprising a socket body and a plug, a groove is opened on the socket body, and a jack is arranged at the bottom of the groove; the plug includes The base, the boss that is arranged on the front of the base to match the groove, and the metal pin that is arranged on the top of the boss; the back of the base of the plug is provided with a tail jack; the side of the boss is provided with a contact switch; the tail plug A spring sheet is arranged in the hole; the contact switch is set in cooperation with the opening and closing of the spring sheet; the socket body, the base and the boss are all made of insulating materials.

The purpose of the utility model is to provide a socket, which can prevent electric shock accidents caused by negligent operation of users or children's careless touching.

The plug has a three-layer tower structure, the first layer is a metal pin, the second layer is a boss made of insulating material combined with the groove, and there is a contact switch on its side, and the third layer is the plug. Grip end (i.e. base).

The setting of the boss on the second layer of the plug and the groove of the socket ensures the isolation of the operator from the live metal part (the connection position is completely closed); when the plug is inserted into the socket body, the socket on the side of the plug The contact switch is closed, and the spring piece inside the plug is controlled to close the tail jack at the tail, so that the ordinary plug cannot be inserted into the power supply; the ordinary plug can only be inserted into the tail when the plug described in the utility model is not inserted into the socket body At this time, after inserting the plug into the socket body, the contact switch is still in the closed state, driving the spring piece in the tail jack to fix the inserted ordinary plug, so that the ordinary plug cannot be pulled out when it is charged; The setting of the point switch and the spring piece ensures that the ordinary plug can only be inserted into the plug when it is not charged, and the ordinary plug can only be pulled out after the plug is pulled out from the socket body (the touch Click the switch to open the spring leaf, and the ordinary plug can be pulled out). The cooperation of the contact switch and the spring leaf is an existing known technology, and multiple structures can be used for selection.

Further, the top of the groove is provided with a baffle limited by a spring.

The socket is provided with a protective baffle, and when not in use, the baffle is under the action of the spring, so that the groove of the socket is in the blocking state of the baffle; it can prevent children from touching the socket, and can also prevent sundries from entering into the jack.

The utility model effectively prevents electric shock accidents caused by personnel negligence through the design of the inner concave socket body and the matching plug; the ordinary plug can only be pulled out from the plug when it is not charged. It also ensures the safety of operation. The utility model has the advantages of simple structure, convenient and safe use, and low production cost. the

Detailed ways

A kind of recessed anti-shock socket, comprising a socket body 1 and a plug, the socket body 1 is provided with a groove 2, and the bottom of the groove 2 is provided with a jack 3; the plug includes a base 4, arranged on the base 4. The boss 5 on the front that matches the groove 2 and the metal pin 6 that is arranged on the top of the boss 5; the back of the base 4 of the plug is provided with a tail jack 7; the side of the boss 5 is provided with a contact switch 8. There is a spring piece in the tail jack 7; the contact switch 8 is set in cooperation with the opening and closing of the spring piece; the socket body 1, the base 4 and the boss 5 are all made of insulating materials.

The top of the groove 2 is provided with a baffle 9 limited by a spring.

The cross section of the socket body 1 is back-shaped (Figure 1), and the cut surface is concave (Figure 2); the cut surface of the plug is convex (Figure 3); the projection of the plug on a plane perpendicular to the metal pin 6 It is back shape.

The tail socket 7 is connected with the metal plug 6 through an internal circuit.

The utility model will be further described below through specific embodiments.

As shown in Figure 1, a socket body 1 has a groove 2 in its middle part, the bottom of the groove is a socket 3, and the top of the groove 2 is provided with a baffle 10, the baffle 10 can close the groove 2, so that The socket 3 at the bottom of the groove 2 is in a closed space.

Based on the above, when the socket is not in use, the jack 3 is inside the closed groove 2, which prevents foreign objects from entering the jack 3 and accidental electric shock to children.

The plug is shown in Figure 3, the second layer (boss 5) is insulating material, the size is equivalent to the size of the groove 2 of the socket, and the height of the second layer is greater than the height of the metal pin 6 (first layer) .

Based on the above, when the plug is in use, the combination of the second part and the groove 2 isolates the operator from the live metal part, avoiding safety accidents caused by negligence of the operator.

As shown in Figure 3, there is a contact switch 8 on the side of the second part of the plug, and a tail jack 7 of a common plug is provided at the tail (Figure 4). There is a spring piece 9 inside the tail jack 7, which is controlled by the contact switch 8 , when the contact switch is closed, the spring leaf 9 is compressed, so that the common plug cannot be pulled out or inserted.

The plug is inserted into the socket, the second part of the plug is combined with the groove of the socket, the depth of the groove 2 is equivalent to the height of the second part of the plug, and the contact switch 8 on the side of the plug is on the inner wall of the groove 2 Closes under pressure.

Based on the above, the setting of the contact switch 8 ensures that the common plug cannot be pulled out or inserted into the plug when the plug is charged, which avoids safety accidents caused by operator negligence.

Fig. 5 is a schematic structural diagram of the cooperation between the spring piece 9 and the contact switch 9 in a specific application. When the plug is inserted into the socket body 1, the contact switch 8 is squeezed, and the spring piece 9 is driven to close the tail jack 7; When the plug is separated from the socket body 1, insert the ordinary plug into the tail jack 7, and then insert the plug into the socket body 1. At this time, the contact switch 8 is squeezed, and the spring leaf 9 tightly blocks the ordinary plug so that it cannot be arbitrarily Pull out; only when the plug is pulled out from the socket body 1, the ordinary plug can be pulled out from the plug, ensuring safety. The direction of the arrow is the movement direction when the contact switch 8 is squeezed. The spring piece 9 generally has a curved structure and is made of a material with better elasticity, which is convenient for closing and opening the tail jack.
