Description

Improved socket

technical field

The utility model relates to a socket, in particular to a socket with an improved structure that conducts when a plug is inserted, and is in a power-off state when the plug is not inserted, has safety functions, and can prevent dust and water from entering.

Background technique

At present, most of the known sockets do not have a safety control device, and are simply sockets for plugging in a power source. In other words, the socket is still powered on when the plug is not inserted, so children may insert metal rods and cause accidental electric shocks. Moreover, the jack of the known socket is in an open state, and there is a problem that dust enters and affects conduction, and even water enters to cause a short circuit and an electric leakage accident. Therefore, the known socket lacks the effect of safety protection. In addition, some known sockets are connected with an "electronic component circuit board" to control the power on when in use and the function of power off when not in use, but the electronic component circuit board has the problem of "high cost and high price". The problem of "big volume" is not suitable for sockets generally assembled in walls, but only for certain machine-specific sockets.

Detailed ways

In order to describe the structure, features and effects of the present utility model in detail, the following preferred embodiments are given below together with the accompanying drawings.

As shown in Figures 1 to 8, the socket provided by the utility model includes: a bottom shell 10, an upper shell 15, and a power control unit 20. The plug piece 11 is provided with a power clip 13 and a power conductive piece 12, and the power conductive piece 12 and the plug piece 11 are separated without contact when the plug is not inserted, so that the plug piece 11 is powered off. The upper case 15 is provided with two power jacks 16, grounding jacks 17, and through holes 18. The power control unit 20 is provided with a control rod 24 and a control block 25. The bump 241 of the control rod 24 protrudes from the through hole of the upper case 15. 18, the control block 25 is arranged between the two power supply conductive sheets 12, when the plug is inserted into the power socket 16 of the upper case 15, the projection 241, the control rod 24 and the control block 25 can be pressed down, and the control block 25 It can also press and push the two power supply conductive pieces 12 to contact the two plug-in pieces 11, so that the power supply of the power supply conductive pieces 12 is conducted to the plug-in pieces 11. The power control unit 20 is provided with a positioning seat 21 installed in the bottom shell 10. The positioning seat 21 is provided with a perforation 22 for the control rod 24 to pass through the combination. The control rod 24 is covered with a spring 242 to form a combination of the control rod 24 and its lower end. The state that the control block 25 of the control block 25 moves straight up and down along the perforation 22 of the positioning seat 21 . The positioning seat 21 of the power control unit 20 is provided with a shaft seat 23, and the shaft seat 23 is provided with two door sheets 26 and two shaft centers 27, and the two shaft centers 27 are connected with a return spring 28, and the two door sheets 26 are provided with Hook groove 260, the upper end of control rod 24 is then provided with hook piece 240, when the plug is not inserted into upper case 15 power jack 16, two door pieces 26 are the state of covering power jack 16, the hook groove 260 of door piece 26, and Engage with the hook piece 240 of the control rod 24, and the two door pieces 26 can be pushed open when the plug is inserted into the power jack 16 of the upper case 15. In addition, the two locking blocks 19 at both ends of the upper shell 15 are provided with disengagement control blocks 190 , and the second locking blocks 19 are activated by pressing the disengagement control block 190 .

The power supply conducting sheet 12, the power clamping sheet 13, the plug-in sheet 11 and the grounding plug-in sheet 14 of the present utility model adopt conductive copper sheets. The control rod 24 of the power supply control unit 20 of the present utility model, the door sheet 26, the positioning seat 21, and the control block 24 are made of insulating sizing material.

As shown in Figure 3, the power line of the external power supply is connected to the wire clamping sheet 13 and the power supply conductive sheet 12. When the plug 30 is not inserted, the bump 241, the control rod 24, and the control block 2 are in a rising state, and the control block 25 is not in contact. Pressed to the power conductive sheet 12, so the power conductive sheet 12 does not touch the plug-in sheet 11, and the plug-in sheet 11 is in an unpowered state. Moreover, the two door pieces 26 are in a state of covering the power socket 16 of the upper case 15 due to the elastic force of the return spring 28 .

As shown in Figure 4, when the insertion piece of the plug 30 is inserted into the insertion piece 11, it can push away the two door pieces 26, and can press the protrusion 241, the control rod 24, and the control block 25 to descend, and the descending control block 25 again presses and pushes the two power supply conductive strips 12 to contact the two plug strips 12 to form a state that the plug strips 12 are energized. When the plug 30 is drawn out, the elastic force of the spring 242 can push the control block 25 of the control rod 24 to rise (as shown in FIG. 3 ), so that the plug piece 12 returns to the power-off state. When a naughty person inserts a foreign object 31 (for example: iron nails, iron wires), as shown in Figure 5, though the foreign object 31 can touch the plug-in piece 11, because the control rod 24 and the control block 25 are not lowered, the If the power supply conductive sheet 12 is not connected to the plug-in sheet 11, the plug-in sheet 11 is still in a state of no electricity, and there is no risk of electric shock.

When the plug 30 is not inserted, but the projection 241 of the control lever 24 is pressed by hand, the second door sheet 26 is pushed away by the insert without the plug 30, so the hook groove 260 of the second door sheet 26 is still connected with the hook sheet of the control lever 24. 240 hooks up, and as shown in Figure 3, forms the control bar 24 state of door sheet 26 pinning down hook sheet 240, so even pressing projection 241 can not make the control block 25 of control bar 24 descend, also can not open two door sheets 26.

In addition, as shown in Figure 6, the structure of the combination of the utility model and the positioning frame plate 32 is that two locking blocks 19 are arranged at both ends of the upper shell 15, and the two locking blocks 19 can be embedded and engaged with the positioning frame plate 32. The socket is assembled in the positioning frame plate 32 (as shown in FIG. 7 ) in the locking groove 33 provided correspondingly on the top. When it is necessary to detach the socket, as shown in Figure 8, press the detachment control block 190 at both ends of the upper shell 15, so that the locking block 19 is retracted from the locking groove 33 of the positioning frame plate 32, and the socket can be detached, in other words, There is no need to use tools such as a screwdriver to assist detachment as the known ones, and the detachment can be detached by pressing the detachment control block 190 by hand, which is convenient, fast and simple.

It can be seen from the above description that when the plug 30 is not inserted in the utility model, the plug piece 11 has no electricity, so there will be no accidental electric shock, and it has a safety effect, and the door piece 26 can cover the power jack 16, which prevents dust or water. Enter the effect of the socket, and have the effect of conveniently detaching the positioning frame plate 32, so the utility model has obviously improved effect and excellent practicability.
