As shown in fig. 1-5, the present invention provides a high safety receptacle comprising a housing 100 and at least one jack assembly 200. The jack assembly 200 is mounted within the housing 100.

The jack assembly 200 includes a housing 210, a base 220, a slider 230, a first contact 240, a first return spring 250, a line source connector 260, a second contact 270, and a second return spring 280.

The housing 210 is cylindrical and rotatably connected to the housing 100, the housing 210 has a first mounting hole along an axial line thereof, the first mounting hole is also cylindrical, the top of the housing 210 has a first jack for inserting a plug, the number of the first jacks is two or three, and the first jacks correspond to two-hole sockets and three-hole sockets for inserting two-wire plugs and three-wire plugs, respectively. Since the two-jack and three-jack receptacles have the same receptacle assembly except for the difference in the number of the related structures due to the difference in the number of the jacks, the two-jack receptacle is re-drawn in the drawings.

The base 220 is installed in the first mounting hole and is connected with the shell 210 in a rotating manner, the base 220 is fixedly connected with the shell 100, the top of the base 220 is provided with second jacks equal to the first jacks in number, and the second jacks are used for inserting plugs.

And when the shell 210 rotates a certain angle around the rotation axis 212 thereof, the first jack and the second jack correspond to each other.

A first sliding groove is formed in one side of the second insertion hole, the sliding block 230 is slidably mounted in the first sliding groove, and an inclined plane is formed at the top of one side, facing the first sliding groove, of the sliding block 230.

A second mounting hole is formed in one side, away from the second jack, of the first sliding chute, the first contact 240 is fixedly mounted in the second mounting hole, and one side, away from the second jack, of the first contact 240 is set to be arc-shaped corresponding to the outer diameter of the base 220 and flush with the outer peripheral surface of the base 220.

The first contact 240 is provided with a slide hole, and one side of the slide block 230 facing the first contact 240 is provided with a slide rod, and the slide rod is slidably inserted into the slide hole.

The first return spring 250 is installed in the first sliding groove and sleeved on the sliding rod, two ends of the first return spring respectively abut against the sliding block 230 and the first sliding groove, and in a natural state, the first return spring 250 bears pressure to provide stress for keeping the sliding block 230 abutting against the second insertion hole.

A line source connector 260 is fixedly mounted on a side of the first contact 240 facing away from the second jack, for connection to live, neutral or ground,

one end of the second contact 270 is slidably connected to the line source connector 260, and the other end extends in the direction of the first contact 240 to be in contact with the housing 210, and the side of the second contact 270 facing the first contact 240 is formed in an arc shape corresponding to the outer diameter of the base 220.

The second return spring 280 is sleeved on the second contact 270, two ends of the second return spring are respectively abutted against the line source connector 260 and one end of the second contact 270 facing the first contact 240, and the second return spring 280 bears pressure in a natural state and is used for providing stress for abutting the second contact 270 and the shell 210.

The side wall of the housing 210 is provided with a through hole, two sides of the through hole in the axial direction of the housing 210 are provided with inclined planes, and one side of the through hole close to the center of the through hole is a lower end, and when the first jack and the second jack are opposite, one end of the second contact 270 facing the first contact 240 can penetrate through the through hole to be abutted against the first contact 240. Preferably, both sides of the second contact 270 corresponding to both sides of the through-hole, which are provided as inclined planes, are also provided as inclined planes, so that the second contact 270 slides out of the through-hole during rotation of the housing 210.

When not in use, the first and second receptacles are offset from each other, and the second contact 270 is separated from the first contact 240 by the housing 210, so that the slider 230 is not conductive.

When the plug-in type reset spring is used, the plug is inserted into the first jack, then the plug is rotated, the plug drives the shell 210 to rotate, when the plug is rotated to the first jack and the second jack to correspond to each other, the plug is continuously inserted into the second jack, and under the action of the inclined plane arranged at the top of the sliding block 230, the sliding block 230 is moved in the direction departing from the second jack by the plug and meanwhile the first reset spring is compressed. This is the plug energized.

After the use is finished, in the process of pulling out the plug, when the plug is pulled out of the second jack, the plug is rotated again to enable the first jack and the second jack to be staggered.

Thus, when the electric shock absorber is not used, because the first jack and the second jack are staggered, a child needs to rotate the first jack and the second jack to corresponding positions against certain resistance and then continue to insert the first jack and the second jack deeper into the first jack so as not to cause an electric shock, and obviously, the electric shock absorber is difficult for the child to perform the actions. Therefore, the utility model provides a socket factor of safety is higher.

In one embodiment, a limit block 211 is installed in the first installation hole, the limit block 211 is fixedly connected with the housing 210, a second sliding groove 221 is formed in the top of the base 220, the second sliding groove 221 is circular and coincides with the axial lead of the base 220, the limit block 211 is slidably arranged in the second sliding groove 221, and when the housing 210 drives the limit block 211 to move from one end of the sliding groove to the other end, the first jack corresponds to the second jack.

Therefore, when the shell 210 is rotated, the shell 210 can be conveniently rotated to the position where the first jack corresponds to the second jack.

In one embodiment, the jack assembly 200 further includes a return torsion spring 290,

the first mounting hole is internally provided with a rotating shaft 212, the rotating shaft 212 is fixedly connected with the housing 210, the top of the base 220 is provided with a third jack, the housing 210 is rotatably connected with the base 220 through the rotating shaft 212 and the third jack, the reset torsion spring 290 is sleeved on the rotating shaft 212, and in a natural state, the reset torsion spring 290 bears torsion for providing stress for keeping the limiting block 211 at one end of the second sliding groove 221. Thus, after the plug is pulled out, the housing 210 automatically rotates under the action of the return torsion spring 290, so that the first jack and the second jack are staggered. When we insert the plug into the first jack and the second jack, the housing 210 cannot rotate because the first jack and the second jack are engaged with each other. Therefore, the child can overcome larger resistance when rotating the shell 210, and meanwhile, when the plug is pulled out, the shell 210 can rotate automatically without rotating the shell 210, so that the situation that the shell 210 is forgotten to rotate when the plug is pulled out is avoided, and the first jack and the second jack are located at corresponding positions.

In the specification of the present invention, a large number of specific details are explained. It is understood, however, that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
