In order to solve the problem, this patent provides a waterproof seal socket, aims at solving the problem that the socket can be inserted by foreign matter such as iron wire.

For ease of understanding, the following detailed description of the embodiments of the present application is provided with reference to the accompanying drawings.

Referring to fig. 1-2, a safety socket includes a housing 100, the housing 100 includes a panel assembly 110 and a bottom case 120, the panel assembly 110 includes a first housing 111, a first protection door 112, and a support 113 supporting the first protection door 112, the first protection door 112 is located between the first housing 111 and the bottom case 120; the first protection door 112 has a pushing portion 200, and the pushing portion 200 is configured to drive the first protection door 112 to move under the pushing action of the plug pins so as to avoid the plug pins; the pushing part 200 includes a guard part 210 and a pushing rib 220, the pushing rib 220 being formed at the middle of the guard part 210; the upper surface of the guard 210 forms a guard surface 211, the upper surface of the push rib 220 forms a push surface 221, and the push surface 221 is higher than the guard surface 211; the protection surface 211 is for preventing foreign objects from passing through the first protection door 112; the pushing surface 221 is used for abutting against the plug pins and driving the first protection door 112 to move under the pressing action of the plug pins.

In this embodiment, the safety socket includes a housing 100, and the housing 100 includes a face-piece assembly 110 and a bottom case 120, so that the socket part accommodated in the bottom case 120 or the face-piece assembly 110 can be isolated from the outside. The face-piece assembly 110 includes a first case 111, a first shield door 112, and a support 113 supporting the first shield door 112, the first shield door 112 being located between the first case 111 and the bottom case 120 such that the first shield door 112 can block foreign matter entering from the first case 111. The first protection door 112 has a pushing portion 200, and the pushing portion 200 can drive the first protection door 112 to move under the pushing action of the plug pins to avoid the plug pins, so that the plug pins can be electrically connected with the socket. The pushing part 200 includes a guard part 210 and a pushing rib 220, the pushing rib 220 being formed at the middle of the guard part 210; the upper surface of the protection part 210 forms a protection surface 211, the upper surface of the push rib 220 forms a push surface 221, and the push surface 221 is higher than the protection surface 211, so that the plug pins matched with the push rib 220 can be stably abutted against the push surface 221 on the upper surface of the push rib 220, thereby driving the first protection door 112 to move; when the foreign matter is inserted into the socket, the foreign matter is liable to abut against the protection surface 211 and cannot push the first protection door 112, or the foreign matter cannot stably abut against the push surface 221 and cannot push the first protection door 112, and thus the foreign matter is blocked by the first protection door 112. Thus, the problem that the socket can be inserted by foreign matters such as iron wires is solved.

The pushing portion 200 is a portion corresponding to a plug pin, and when the pin is inserted into the insertion hole 111a, the protective door is pushed open by pressing down the pushing portion 200. In this embodiment, the pushing portion is further configured to be a pushing rib 220 and a protecting portion 210, and the pushing rib 220 is configured to be higher than the protecting portion 210, so that the contact portion with the plug pin is reduced, and when a non-standard plug is inserted, for example, when a minor plays, an iron wire or other relatively fine foreign matters (the larger foreign matters cannot be inserted into the jack, so that there is no risk of electric shock) are inserted into the jack, it is difficult to push the protecting door, thereby ensuring the safety of electricity consumption. When the plug pins are inserted into the insertion holes 111a in this embodiment, the plug pins can be stably abutted against the pushing surfaces 221 of the pushing ribs 220, so that the protective door can be pushed open, and when a foreign object is inserted, the plug pins can be easily abutted directly against the protective surface 211, and the protective surface 211 is pressed down, so that the protective door cannot be pushed, and thus the insertion of the foreign object can be prevented.

In addition, when the foreign matter is inserted, if the foreign matter is just abutted against the pushing surface 221, the pushing surface 221 cannot be stably pressed down because the foreign matter cannot be perfectly matched with the insertion hole, and the foreign matter easily slips onto the protecting surface 211 when the foreign matter is forcibly inserted, so that the protecting door is difficult to push. Therefore, the embodiment can effectively reduce the safety risk of electricity consumption and reduce the occurrence of electric shock accidents. Of course, the present embodiment also cannot completely prevent the occurrence of electric shock accidents by the structural design, and if the conductive foreign matter which is basically the same as the plug pins is inserted into the insertion holes 111a, the protective door may still be pushed open. The foreign matter insertion hole 111a which is basically the same as the plug pin is used, and the foreign matter insertion hole 111a is not used, if the possibility of foreign matter insertion is completely eradicated, the normal plug pin is difficult to insert, so that the socket cannot be used normally, and the purpose of the embodiment is to improve the safety of the socket, enhance the protection of the foreign matter and reduce the possibility that the foreign matter can be inserted into the socket.

The technical purpose mentioned above is achieved thanks to the design that the pushing surface 221 is higher than the protecting surface 211. The protective surface 211 is lower than the pushing surface 221, and the protective surface 211 can be made more gentle than the pushing surface 221, so that it is difficult to generate a sufficient lateral pushing force to push the protective door when an object inserted from the insertion hole abuts against the protective surface 211. To further enhance the protective effect of the protective surface 211, a preferred implementation is provided.

Referring to fig. 5 and 7, the angle between the protection surface 211 and the insertion direction of the plug pin is not less than 85 °. In this embodiment, the included angle between the protection surface 211 and the plug pin insertion direction is not less than 85 °, and when the foreign object insertion hole is abutted against the protection surface 211 and pressed down, the lateral thrust generated by the foreign object insertion hole is smaller than the minimum thrust required for pushing the protection door. Note that, when the minimum pushing force pushing the protective surface 211 to move is not a fixed value, but a basic resistance force plus a maximum static friction force that can be generated between the protective door and a structure supporting the protective door when the foreign matter presses the protective surface 211 downward. The limitation of the angle in the embodiment can ensure that the protective door cannot be pushed open when the foreign matter is normally inserted into the jack.

It should be noted that, the first protection door 112 cannot be pushed by the foreign matter through the protection surface 211 and the included angle between the plug pin insertion direction is not less than 85 degrees, and in the implementation manner that the included angle between the protection surface 211 and the plug pin insertion direction is not less than 85 degrees, further, the application provides a preferred implementation manner.

Referring to fig. 5 and 7, the protection surface 211 is perpendicular to the insertion direction of the plug pins. The perpendicular angle setting can not produce the power that transversely promotes the guard gate and remove when making the foreign matter butt guard 211 to, the degree of difficulty of dialling the guard gate when can increase handheld foreign matter and stir guard 211, further improves the power consumption safety.

In addition, in the present embodiment, the protection surface 211 is perpendicular to the insertion direction of the plug pins, so that the requirements on the process are relatively simple when the first protection door 112 is produced, the production and the manufacturing are easy, and the manufacturing cost of the product can be significantly reduced.

It should be noted that, based on the technical scheme that the plug pins push the first protection door 112 by abutting the pushing surface 221 on the first protection door 112, in the case of maintaining the protection capability of the protection door, in order to ensure that the plug pins can smoothly push the protection door when being inserted into the insertion holes 111a, the following scheme is further provided in the present application.

Referring to fig. 5 and 7, the pushing portion 200 further includes a first guiding portion 230 located at an upper end of the pushing rib 220, and the first guiding portion 230 is located above the protecting portion 210; the upper surface of the first guide 230 is smoothly transitioned or disposed coplanar with the pushing surface 221.

In this embodiment, the first guiding portion 230 is disposed at the upper end of the pushing rib 220, so that the plug pin is guided by the first guiding portion 230 when inserted, thereby smoothly pushing the protective door, so that the plug pin can smoothly slide toward the pushing surface 221, and the protective door is pushed open by the action of the pushing surface 221. In addition, the first guide 230 is located above the guard 210 such that the first guide 230 does not guide the plug pins to the guard surface 211, thereby allowing the plug pins to precisely slide toward the push surface 221. When the protective door is pushed from a static state, the required pushing force is slightly larger than the pushing force required in the process of pushing the protective door, if the pins are inserted to directly push the protective surface 211, the pressure born by the place where the pushing surface 221 is initially contacted with the pins is larger, deformation is easy to be caused, and after a certain number of plugging times is reached, the pins can not push the protective door any more. This application has divided the promotion rib 220 and the guard 210 with the promotion part, and the area of the promotion face 221 of promotion rib 220 reduces, bears under the unchangeable circumstances of pressure of participating in, and pressure can be bigger, consequently, under the same material, causes the promotion rib 220 to warp more easily, and life can reduce, and this embodiment sets up the guide that is located promotion portion 200 and guard 210 top, can effectively reduce the pressure to the promotion face 221, avoids because of the great damage to guard 210 of initial thrust, increases the plug number of times of product, prolongs the life of product.

There are some dimensional tolerances that are unavoidable for the socket housing or the guard door itself, resulting in the push rib 220 being slightly inclined so that the width direction of the plug pins cannot push the rib 220 vertically. Therefore, when the plug pins completely push the protective door downward to insert into the socket, the plug pins may be blocked at the edge of the protective part 210 when pushing to the lower end of the pushing rib, so as to avoid the pins from being blocked at the protective part 210 when pushing to the lower end of the pushing rib 220. Referring to fig. 4, the pushing portion 200 further includes a second guiding portion 240 located at a lower end of the pushing rib 220, and the second guiding portion 240 is located below the protecting portion 210; the upper surface of the second guide 240 is smoothly transitioned or disposed coplanar with the pushing surface 221.

In the present embodiment, the second guiding portion 240 is disposed below the protecting portion 210, and the upper surface and the pushing surface 221 are smoothly over-laid or coplanar, such that the foreign objects are guided by the second guiding portion 240 and not blocked at the edge of the protecting portion 210.

In order to reset the first protection door 112 after the plug pin is pulled out, referring to fig. 2, the safety socket further includes a first return mechanism 300, where the first return mechanism 300 is disposed on one side of the first protection door 112, so as to drive the first protection door 112 to reset when the plug pin is pulled out of the socket. In this embodiment, a first restoring mechanism 300 is disposed on one side of the first protection door 112, so that the first protection door 112 is driven to reset when the plug pins are pulled out of the socket.

It should be noted that, when the foreign matter abuts against the pushing surface 221, the pushing surface 221 is required to enable the foreign matter to be unable to stably abut against the pushing surface 221, so that the foreign matter cannot push the first protection door 112, and the specific implementation manner meeting the above-mentioned requirement is not limited, and for convenience of understanding, a preferred implementation manner is provided in the present application.

Referring to fig. 7, the width of the pushing surface 221 is not less than 0.5mm and not more than 3mm.

The narrower the pushing surface 221, the more difficult it is for the foreign matter to push the shield door, but the thickness of the pushing rib 220 cannot be made thin without limitation under the existing material technology conditions. In this embodiment, the width of the pushing surface 221 is set between 0.5mm and 3mm, so that the foreign matter cannot be stably abutted against the pushing surface 221 under the condition of meeting the strength requirement, and thus the first protection door 112 is difficult to be pushed by the foreign matter.

In order to improve the stability of the first protection door 112 inside the socket housing, the first protection door 112 can be pushed more smoothly when the plug pins are inserted.

Referring to fig. 5 and 7, the first protection door 112 further includes a holding portion 112a, and the first protection door 112 is held by the holding portion 112a to the supporting member 113.

In the present embodiment, the first protection door 112 is provided with the holding portion 112a, so that the first protection door 112 can be held by the holding portion 112a to the supporting member 113.

The specific form of the supporting member 113 is not limited, and may be engaged with the first protection door 112, and may be adaptively set according to the specific structure of the first protection door 112.

Another specific embodiment is presented for the support. In this embodiment, referring to fig. 1-2 and fig. 5, the face housing assembly 110 further includes a second housing, and the second housing is located inside the first housing 111; the second housing forms a support 113. The face shell assembly 110 is arranged in a mode of combining the first shell 111 and the second shell, and the first protective door 112 is arranged in the face shell assembly, so that the socket is convenient to assemble, and the labor cost of an assembling process is saved.

The solution of the present application cannot completely eliminate all risks, for example, by deliberately pulling the first protection door 112 with a suitable tool, and still possibly pulling the first protection door open, so that the foreign matter enters the socket.

In order to further improve the protection effect, another embodiment is provided. In this embodiment, referring to fig. 1 to 4, a second protection door 114 is further disposed on the inner side of the first housing 111, and the second protection door 114 is located above the first protection door 112.

In this embodiment, by providing the second protection door 114 above the first protection door 112, it is difficult for the foreign matter to pass through the two layers of protection doors at the same time, thereby further preventing the foreign matter from entering the interior of the socket.

In order to close the jack 111a when the plug pin is not inserted into the jack, the application further proposes an embodiment, in this embodiment, referring to fig. 8, the first housing 111 is provided with the jack 111a, and the second protection door 114 is provided at the jack 111a to block or open the jack 111a; a guide structure 400 is arranged below the first shell 111, the guide structure 400 comprises a guide chute 410 or a guide sliding rail which extends downwards in a tilting manner, and the second protective door 114 is provided with a guide sliding block matched with the guide chute 410 or a guide sliding block or a guide groove matched with the guide sliding rail; the second protection door 114 is configured to generate downward displacement and lateral displacement under the pressing action of the plug pins and the guiding action of the guiding structure 400 when the plug pins are inserted into the insertion holes 111a, so that the second protection door 114 dodges the plug pins to enable the plug pins to be downward abutted against the pushing portion 200 of the first protection door 112.

In the present embodiment, by blocking the insertion hole 111a of the first housing 111 using the second barrier door 114, the receptacle is enabled to prevent water and conductive liquid from entering the receptacle. The guide structure 400 includes a guide chute 410 or a guide rail extending obliquely downward, and the second protection door 114 is provided with a guide slider or a guide groove adapted to the guide chute 410 or to the guide rail, so that the second protection door 114 can block the insertion hole 111a when the plug pin is not inserted into the insertion hole 111a, and can move in a predetermined direction when the plug pin is inserted into the insertion hole 111a, thereby allowing the plug pin to abut against the pushing portion 200 of the first protection door 112.
