Description

Safety power socket with clamping ^;

Technical field

In order to solve the reliability, the thickness of the clamped copper piece is continuously increased and the superior material is used to enhance the elasticity. Although the problems of safety and tight contact are solved to some extent, there are still many shortcomings, such as the patent that I invented in previous years. No. 00 2 29339. 0 (rotary safety power socket), strictly speaking the two major shortcomings are not solved perfect, first: it is safe to return to 0 only when exiting, but it slightly reverses a little angle and If you do not return to the 0 position, you can pull out the plug and the hole is still dangerous. Second: Structure The plug is a single-sided collision contact, which is prone to arc damage to the surface of the plug, affecting the next-use effect, that is, the life, and does not meet the requirements for double-sided contact in some countries. The force of the protective door can still be inserted. There are unsafe factors that can be dangerous. The difficulty of inserting and removing tightly contacted products exceeds the national regulations. When used, it must be forced to operate beyond the prescribed strength, which is prone to danger. The result is that it is lost. Not solved ideally.

Multiplicative safety and reliability still pose a risk hazard.

The hollow core 6 can be pushed downward by the plug 18. The plugless anti-push device prevents dangerous displacement. Figure ⁸ is a cross-sectional view showing the state of the present invention: The working principle and process of the present invention will be further described below with reference to the accompanying drawings:

The positioning mechanism of the present invention functions to bring the hollow core in the original state or the energized working state (high position) in which the hollow core rises.

In the original state, the conductive clip 1 of the ratchet clamping mechanism is in the position shown in Figs. 1 and 4, that is, the ear contour side of the conductive clip 1 corresponds to the upper half of the conductive sheet 1 - 5 and 2 due to hollowness. The position of the core body 6 is in a vertical position, and is not in contact with the inclined conductive sheet 3-1 of the power supply terminal 3 at a certain interval, and is not energized at jtb.

As shown in Fig. 8 and Fig. 5, when the plug 18 is pressed, the hollow core body 6 rises to a high position under the action of the positioning mechanism, and the conductive clip 1 with the M hook is moved upwards, due to the inclined conductive sheet. 3 - 1 does not move, the upper half of the ear contour 1 - 5 tends to be the same as the conductive sheet 3 - 1 due to the elastic deformation process, and is in contact with the conductive sheet 3 - 1 4 and is energized; The conductive sheet 3 - 1 presses the ratchet 2 against the plug 18 to form a clamped state. At this time, when the plug 18 is photographed, due to the angle formed between the inclined conductive sheet 3-1 and the plug 18, when the ratchet 2 is rolled toward the top by the plug 18, a 3⁄44 tightening effect is generated, Tightly clamping the plug 18 prevents pulling out, and at the same time, the contact between the conductive sheet 3-1 and the plug 18 is more closely energized.

Push the plug 18 again, the hollow core 6 will return from the high position to the low position. At this time, the conductive clip 1 has left the conductive sheet 3 - 1 and is powered off. At the beginning of the state, the plug can be pulled out.

In the socket using the rotary type 4; 1 hook, except for the above, the other structures are the same.

To the opening 19; The anti-rotation pin 15 of the anti-rotation mechanism has a square shape, is placed in the square groove 20 at the lower end of the cover 8, and the other end is inserted into the upper portion of the recess 6-1 of the hollow core, and the square groove 20 has a return spring 21.

In the initial state, the two wings 16 are in the groove 17, and the hollow core body 6 is in the vertical direction. The working principle is: Only the insertion plug pushes the anti-rotation pin 15 and the anti-rotation pin 15 leaves the hollow core body 6 to pass. The plug 18 rotates the hollow core by an angle, and the wings 16 are disengaged from the recess 17 and the vertical opening 19 in the housing, so that the hollow core 6 reaches the high position. Others are similar to the above structure and work.

The conductive clip with the ratchet clamping mechanism is a preferred embodiment of the present invention. When there is no ratchet, the upper open ear shaped conductive clip also has a certain clamping function, but without the ratchet effect, the ratchet locking effect cannot be produced.
