Problems solved by technology

[0002] The poor quality of the socket will cause many serious problems, such as: 1) The quality of the socket is not good, and it is easy to produce what is often called ignition, that is, arc
Indicates that the contacts of the socket are not in good contact
2) The quality of the plastic material used for the socket is not good. It is not only toxic, easy to crack, but also unsightly. More importantly, it is easy to catch fire when an arc occurs.
3) For example, the copper parts used for the socket are of poor quality and thin
The socket is not closed, or the quality of the closed door is not good, and children are often knocked down by electric shock and burnt
Some suffered severe burns, and others were amputated after being electrocuted, leaving lifelong regrets

Embodiment 1

[0030] The structure of the safety socket provided by the invention is as Figure 1~3 As shown, a cover plate 2 is provided on the top of the socket body 1, and the cover plate 2 and the socket body 1 are movably connected to each other through a rotating shaft 3 located on the upper edge of the socket body 1; figure 2 , under the socket body 1, a first protruding shaft 4 facing upwards is provided, a first collar 6 is provided under the inner side of the cover plate 2, a connecting rod 5 is sleeved in the first collar 6, and connected The upper end of the rod 5 is fixed with a first groove 7, and when the cover plate 2 is closed, the first groove 7 can be sleeved on the first protruding shaft 4; as image 3 , a second groove 8 is provided on one side of the socket body 1, the notch of the second groove 8 faces outward, and a second collar 9 is also arranged on the same side inside the cover plate 2, and the second collar 9 A fixed rod 10 is sleeved in the middle, and the fi...

Embodiment 2

[0033] In order to improve the flame retardancy of the plastic, the present invention also provides a method for preparing the flame retardant plastic on the cover plate 2 and the socket body 1, the steps are as follows:

[0034] Step 1. In parts by weight, take 20 parts of methyltriethoxysilane, add it to 400 parts of water, and perform hydrolysis under the action of 0.2 parts of formic acid as a hydrolysis catalyst. The hydrolysis reaction time is 2 hours, and the hydrolysis temperature is 3°C After the hydrolysis is completed, the temperature is raised to carry out the polymerization reaction, and after the reaction is completed, the vacuum distillation is carried out to obtain the silicone resin;

[0035] Step 2. Mix 20 parts of isophthalic acid and 20 parts of neopentyl glycol, heat up, and carry out condensation reaction under the protection of argon. The temperature of condensation reaction is 170°C. The acid value of the reaction system under the condition of terminatin...

Abstract

The invention relates to a safety socket with good protection performance, and belongs to the technical field of electrical equipment. The upper portion of a socket body is provided with a cover plate, and the cover plate and the socket body are movably connected through a rotating shaft disposed at the upper edge of the socket body; a first protruding shaft oriented upwards in terms of direction is arranged below the socket body, a first sleeve ring is arranged below the inner side of the cover plate, a connecting rod is sleeved by the first sleeve ring, a first groove is fixed to the upper end of the connecting rod, and when the cover plate is closed, the first protruding shaft can be sleeved by the first groove; and one side of the socket body is provided with a second groove, the notch of the second groove is oriented towards the outer side, a second sleeve ring is also arranged at the same side of the inner side of the cover plate, a dead lever is sleeved by the second sleeve ring, and when the cover plate is closed, the dead lever can be sleeved by the notch of the second groove. The safe socket with a cover, provided by the invention, can prevent children from touching a socket port by hands and accordingly prevents electric shock.

Description

technical field [0001] The invention relates to a safety socket with good protection performance, which belongs to the technical field of electrical equipment. Background technique [0002] The poor quality of the socket will cause many serious problems, such as: 1) The poor quality of the socket is prone to the so-called ignition, that is, arcing. Indicates that the contacts of the socket are not in good contact. 2) The quality of the plastic material used for the socket is not good. It is not only toxic, easy to crack, but also unsightly. More importantly, it is easy to catch fire when an arc occurs. 3) For example, the copper parts used for sockets are of poor quality and thin. If the number of times of plugging and unplugging is more, it will not work well. 4) The most important security. Good outlets have closed doors. When children are ignorant and occasionally use iron wires, needles, spoon handles and other metal objects to poke the socket holes, they will not b...
