Description

Anti-off safety socket

technical field

The invention relates to a wire socket, in particular to an anti-off safety socket.

Background technique

In daily life, the use of plugs and sockets is quite common. Generally speaking, the socket has an insulating body with two or three jacks, and electrodes are arranged in the jacks. The plug has two or three blades that are inserted into the receptacles of the socket to make contact with the electrodes therein.

When the plug is inserted into the socket, the plug blade of the plug will press the electrode pad and cause the electrode pad to deform, so that the plug can be restrained on the socket. After a period of use, the binding force will become smaller and smaller due to metal fatigue, so the plug is easy to fall off. In addition, in our daily life, we often encounter situations where we accidentally kick the wire and cause the plug to fall off. If this happens in a factory, it will cause the machine to stop abnormally, and the loss may be huge.

Therefore, there are some sockets that provide anti-off functions in the market, but the anti-off mechanisms of these anti-off sockets are usually quite complicated and very cumbersome to use.

Contents of the invention

In view of the above problems, the main purpose of the present invention is to provide an anti-off safety socket, which has a simple structure and is easy to use.

In order to achieve the above object, the present invention provides an anti-off safety socket, which includes an insulating shell with several jacks, each of which is provided with an electrode, and is characterized in that: at least one one-way interference piece, It is arranged in the insulating shell, which makes the insertion of the plug unaffected, but interference will occur when the plug is pulled out.

The one-way interfering member has an elastic section inclined toward the inner end of the insertion hole, and the outer end of the elastic section is located in the insertion hole.

The outer end of the elastic section is rough.

A release piece is also included, which can release the interference state of the one-way interference piece on the plug blade.

A release part is also included, which can press the elastic section of the one-way interference part to make it bend inward again, so as to release the interference state of the one-way interference part on the plug blade.

The release member has at least one guide piece, which can enter into the corresponding insertion hole, and has an inclined surface on one side to contact with the elastic section of the one-way interference member.

The release member has at least one guide piece, which can enter into the corresponding insertion hole, and has a hook at its outer end.

A spring is also included, arranged between the release piece and the insulating body, so that the guide piece of the release piece is located away from the insertion hole in an initial state.

By adopting the above technical solution, the present invention cleverly uses the bending angle of the elastic section of the one-way interfering member, so that the plug will not be affected when inserted, but will be interfered by the one-way interfering member and cannot be pulled out when pulled out. In this way, it can be ensured that the plug will not be pulled out due to unexpected factors. In addition, when the plug is pulled out, it is only necessary to press the release part, which indeed achieves the purpose of the invention of simple structure and convenient operation.

Detailed ways

In order to describe the structure, characteristics and achieved effects of the present invention in detail, the following preferred embodiments are given below and described with reference to the accompanying drawings.

As shown in FIGS. 1 to 4 , the anti-off safety socket provided by the present invention mainly includes: an insulating body 10 , two one-way interference members 28 and a release member 34 .

The front side of the insulating body 10 has three jacks 12 , 14 , one of which is a ground jack 14 . The three electrodes 16 are respectively accommodated at the rear ends of the jacks 12 and are electrically connected to predetermined electrical appliances (not shown in the figure). The top side of the insulating body 10 has an opening 18 communicating with each socket 12 . Below the opening 18 there are two L-shaped fixing slots 20 located between the two insertion holes 12 . A cover 22 is used to close the opening 18 . The cover 22 has two holes 24 and a recess 26 is formed between the two holes 24 .

Each one-way interference element 28 is a metal sheet and has a fixed section 30 and an elastic section 32 . The fixing section 30 can be inserted into the fixing slot 20 of the insulating body 10 , so that the front end of the elastic section 32 is located in each insertion hole 12 . The inner end of each elastic section 32 is inclined towards the insertion hole 12 and can be deformed under pressure, and the outer end of each elastic section 32 is not smooth and is in a rough state.

The release member 34 has a pressing portion 36 and two guide pieces 38 located on the bottom side of the pressing portion 36 . Each guide piece 38 has a hook portion 40 at its outer end, the hook portion 40 can prevent the releasing member 34 from coming off, and one side of the hook portion 40 has a slope 41 . The two guide pieces 38 are inserted into the insulating body 10 through the two holes 24 of the cover 22 and correspond to the two insertion holes 12 , and the pressing portion 36 is left outside the insulating body 10 . A spring 42 is disposed between the insulating body 10 and the pressing portion 36 . A bottom side of the pressing portion 36 has a recess 44 , and two ends of the spring 42 are respectively accommodated between the recess 26 of the cover 22 and the recess 44 of the pressing portion 36 .

As shown in Figure 5, when the plug blade 48 of a plug 46 was inserted in the socket 12,14 of the anti-off safety socket of the present invention, the elastic section 32 of each one-way interference member 28 can be compressed and deformed inwardly, with This leaves room for the plug blades 48 to move inwardly to make contact with the electrodes 16 . When the user pulls out the plug 46 without operating the release member 34, the two elastic segments 32 will be driven to The outward bending causes an interference state between the plug piece 48 and the elastic section 32 , and the greater the applied force, the more serious the interference state, so the user cannot pull out the plug 46 .

As shown in Figure 6, when the user wants to pull out the plug 46, he must first press the release member 34. At this time, the second guide piece 38 will enter the second jack 12, and the slope 41 on the second guide piece 38 will cause the second elastic The section 32 is bent inward again to release the interference between the plug piece 48 and the elastic section 32 , so that the user can pull out the plug 46 smoothly.

To sum up, the present invention only cleverly uses the bending angle of the elastic section of the one-way interfering element, so that the plug will not be affected when inserted, but it will be interfered by the one-way interfering element and cannot be pulled out when pulled out. In this way, it can be ensured that the plug will not be pulled out due to unexpected factors. In addition, when the plug is pulled out, it is only necessary to press the release part, which indeed achieves the purpose of the invention of simple structure and convenient operation.
