Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the related art, the socket protection door can cover live jacks (live wire jacks and zero wire jacks) of the socket so as to protect the use of the socket. The socket protective door is usually connected with a spring, and when a plug is inserted into the socket, the socket protective door moves to expose the live jack and drive the spring to generate elastic deformation; when the plug is pulled out of the socket, the socket protection door is usually reset by a spring. However, the spring may be bent and deformed in the process of elastic deformation, so that a deviation exists between the position after the spring is reset and the position when the spring is not bent and deformed, and therefore the reset position of the socket protection door is deviated, a gap exists between the socket protection door and the jack, fingers or metal bars of children can be inserted into the jack of the socket, and potential safety hazards are easy to generate.

In a first aspect, please refer to fig. 1, an embodiment of the present application provides a socket protection door 2 for protecting a hot slot 72 and a neutral slot 73 of a triple-outlet socket 7 (as shown in fig. 5), so as to improve the safety of the triple-outlet socket 7 during use. The socket protection door 2 includes a solid member 3, a shutter 4, and a spring 5. The solid piece 3 of this application embodiment can play the guide effect to the displacement motion of shielding piece 4, avoids shielding piece 4's reset position to take place the deviation to make shielding piece 4 can protect live wire slot 72 and zero line slot 73 of three hole sockets 7 better.

Referring to fig. 1 and 2, the fixing member 3 serves as an appearance member in the socket protection door 2 and provides a setting basis for the shielding member 4 and the spring 5. The fixing element 3 has a hole plate 31 and a first guide rail 32 protruding from the hole plate 31, the hole plate 31 has a ground hole 311, a live hole 312 and a neutral hole 313, it can be understood that, when the socket protection door 2 protects the three-hole socket 7, please combine fig. 5 together, the ground hole 311, the live hole 312 and the neutral hole 313 should respectively correspond to the ground slot 71, the live slot 72 and the neutral slot 73 of the three-hole socket 7, so that the three-hole plug 6 (as shown in fig. 6) can be electrically connected to the three-hole socket 7, it can be understood that the arrangement of the ground hole 311, the live hole 312 and the neutral hole 313 can guide the process of inserting the three-hole plug 6 into the three-hole socket 7, and it is more convenient to electrically connect the three-hole plug 6 and the three-hole socket 7.

Referring to fig. 1 to 3, the shielding element 4 is used as a protection member in the socket protection door 2 for protecting the live slots of the three-hole socket 7, where the live slots are the live slot 72 and the zero slot 73, that is, the shielding element 4 is used for shielding the live slot 72 and the zero slot 73, so as to prevent dangerous power consumption behaviors such as small metal objects or children's fingers directly extending into the live slot. The shield 4 includes an abutting portion 41, a stopper portion 42, and a shielding portion 43 connected in this order.

The abutting portion 41 is for shielding the ground wire opening 311 and for abutting against the ground wire pin 61 of the three-hole plug 6. It will be appreciated that the three prong plug 6 (shown in figure 6) has a ground pin 61, a power pin 62 and a neutral pin 63, and the length of the ground pin 61 is greater than the lengths of the power pin 62 and the neutral pin 63, so that during the process of inserting the three prong plug 6 into the three prong receptacle 7, the ground pin 61 can be grounded before the power pins 62 and 63 are energized, thereby ensuring the safety of electricity, and similarly, during the process of pulling the three prong plug 6 out of the three prong receptacle 7, the ground pin 61 can remain grounded after the power pins 62 and 63 are de-energized, so as to avoid the occurrence of the electrical leakage phenomenon. Further, in the process that the three-hole plug 6 is inserted into the three-hole socket 7 with the socket protection door 2, the ground pin 61 is firstly abutted against the abutting portion 41, the abutting portion 41 drives the limiting portion 42 and the shielding portion 43 to move under the action force applied by the ground pin 61, so that the shielding portion 43 exposes the live wire opening 312 and the zero wire opening 313, the live wire pin 62 is inserted into the live wire slot 72, the zero wire pin 63 is inserted into the zero wire slot 73, and the process that the three-hole plug 6 is electrically connected with the three-hole socket 7 through the socket protection door 2 is further realized.

It will be appreciated that, since the length of the ground pin 61 is greater than the lengths of the live pin 62 and the neutral pin 63, the difference between the lengths of the ground pin 61 and the live pin 62 (or the neutral pin 63) should be less than or equal to the movement stroke of the abutting portion 41 under the abutting action of the ground pin 61, so that after the ground pin 61 is inserted into the triple-hole socket 7 and grounded, the live pin 62 and the live slot 72, and the neutral pin 63 and the neutral slot 73 can be electrically connected.

Limiting part 42 has guide way 421 with first guide rail 32 sliding fit, and it can be understood that sliding fit between first guide rail 32 and guide way 421 plays the guide effect to the displacement motion of shutter 4, and in order to understand the direction process of this embodiment, further, first guide rail 32 has a direction of guidance L, and guide way 421 has a plurality of cell walls, and the cell wall of guide way 421 and first guide rail 32 sliding fit to make limiting part 42 can follow direction of guidance L and first guide rail 32 sliding fit. Furthermore, when the abutting portion 41 drives the limiting portion 42 and the shielding portion 43 to move under the action force applied by the ground pin 61, the first guide rail 32 is arranged so that the shielding piece 4 can move along the guiding direction L, and the sliding fit between the guide groove 421 and the first guide rail 32 can limit the movement of the shielding piece 4, so as to prevent the shielding piece 4 from deviating from the reset position of the shielding piece 4 due to the bending deformation of the spring 5.

The shielding portion 43 is used for shielding the live wire opening 312 and the neutral wire opening 313 to protect the live jacks of the three-jack socket 7, so as to prevent fine metal objects or children fingers from directly extending into the live slots. The present embodiment does not limit the specific structure of the shielding portion 43, and when the ground pin 61 is not abutted to the abutting portion 41, the projection of the shielding portion 43 in the hole depth direction of the live wire opening hole 312 should cover the live wire opening hole 312 and the neutral wire opening hole 313, so that the shielding portion 43 can better protect the two live jacks of the three-jack socket 7.

It can be understood that, in order to further ensure the electrical safety, the material used for the shielding element 4 should be an insulating material, and the present embodiment does not limit the kind of the insulating material, for example, the shielding element 4 may be made of a plastic material, and the plastic material has the advantage of good processing characteristics, so that the shielding element 4 is easy to be manufactured in a large scale; alternatively, the shielding member 4 may be made of rubber, which has the advantages of wear resistance and high elasticity, so that the shielding member 4 has a long service life.

The spring 5 is provided in the guide groove 421 as a return member in the receptacle protective door 2, and both ends of the spring 5 are connected to the first guide rail 32 and the contact portion 41, respectively.

When the three-jack plug 6 is not inserted into the three-jack socket 7, the spring 5 is arranged so that the shutter 43 shields the live opening 312 and the neutral opening 313 to protect the live jack from the shutter 4; in the process that the three-hole plug 6 is inserted into the three-hole socket 7, the abutting part 41 moves to drive the spring 5 to generate elastic deformation, so that the elastic potential energy of the spring 5 is increased; in the process that the three-hole plug 6 is pulled out from the three-hole socket 7, the spring 5 drives the abutting part 41 to do reset movement under the action of elastic potential energy, so that after the three-hole plug 6 is pulled out from the three-hole socket 7, the shielding part 4 shields the electrified jack of the three-hole socket 7 again.

It can be understood that, for avoiding spring 5 to lead to spring 5 to take place plastic deformation because of excessive bending deformation, plastic deformation makes spring 5's some positions unable realization reset, and then makes spring 5's reset position have the deviation, thereby makes to have the gap to cause the power consumption potential safety hazard between socket protective door 2 and the jack from this. For avoiding the occurrence of such electrical safety hazards, the spring 5 is disposed in the guide groove 421 in this embodiment, so that when the spring 5 is excessively deformed, the groove wall of the guide groove 421 may abut against the spring 5 to reduce the deformation degree of the spring 5 caused by the bending deformation, thereby reducing the probability of the spring 5 causing the plastic deformation due to the excessive bending deformation, and further making the socket protection door 2 have a longer service life and a higher safety.

In the present embodiment, the connection mode of the spring 5 is not limited, for example, the spring 5 may be a compression spring 5, and both ends of the spring 5 respectively abut against the first guide rail 32 and the abutting portion 41; for another example, the spring 5 may be fixedly connected to at least one of the abutting portion 41 and the first guide rail 32, so that the spring 5 has a better returning effect.

In summary, the embodiment of the present application provides a socket protection door 2, including a solid part 3, a shielding part 4 and a spring 5, where the solid part 3 has a hole plate 31 and a first guide rail 32 protruding on the hole plate 31, and the hole plate 31 can play a guiding role in a process of inserting a three-hole plug 6 into a three-hole socket 7, so as to facilitate the electrical connection between the three-hole plug 6 and the three-hole socket 7; the shielding piece 4 comprises an abutting part 41, a limiting part 42 and a shielding part 43 which are connected in sequence, the limiting part 42 is provided with a guide groove 421 in sliding fit with the first guide rail 32, the guide groove 421 and the first guide rail 32 are in sliding fit to limit the displacement motion of the shielding piece 4 so as to avoid deviation of the reset position of the shielding piece 4 caused by bending deformation of the spring 5, and the shielding part 43 is used for shielding the live wire open hole 312 and the zero wire open hole 313 so as to protect the live jack of the three-hole socket 7; the spring 5 is disposed in the guide groove 421, and two ends of the spring 5 are respectively connected to the first guide rail 32 and the abutting portion 41 to drive the abutting portion 41 to perform a reset motion, so as to shield the live jack of the three-hole socket 7.

Referring to fig. 3 and 4, the position-limiting portion 42 further includes two first position-limiting plates 422 disposed at intervals, and the two first position-limiting plates 422 are protruded from the surface of the shielding portion 43 facing the opening plate 31. It can be understood that the two first limiting plates 422 may have the same protruding height, so that the limiting portion 42 may occupy a smaller space, thereby realizing miniaturization of the shielding member 4; first guide rail 32 is located by the clamp between two first limiting plate 422, and guide way 421 is constituted by two first limiting plate 422 and shielding portion 43 at least, and that is to say, two first limiting plate 422 have at least partial cell wall of guide way 421, first guide rail 32 and two first limiting plate 422 sliding connection, make two first limiting plate 422 play the guide effect to the displacement motion of shielding piece 4 from this for shielding piece 4 can carry out displacement motion along direction of guidance L.

The connecting plate 411 is disposed on one side of the two first limiting plates 422 far away from the shielding portion 43, and is fixedly connected to the two first limiting plates 422, and the guide groove 421 is formed by the two first limiting plates 422, the shielding portion 43, the covering plate 423 and the connecting plate 411. Please refer to fig. 3 together, it can be understood that one end of the spring 5 is connected to the connecting plate 411, and the other end of the spring 5 is connected to the first guide rail 32, the connection manner in this embodiment includes but is not limited to at least one of abutting and fixed connection, specifically, the connecting plate 411 may extend a connecting post 4111 into the guide slot 421, one end of the spring 5 may be sleeved on the connecting post 4111 for fixing, and an axial direction of the connecting post 4111 may be parallel to the guiding direction L, so that the connecting post 4111 guides and limits the deformation of the spring 5, that is, the spring 5 is made to perform telescopic deformation along the guiding direction L; further, the connection surface of spring 5 and connection plate 411, the connection surface of spring 5 and first guide rail 32 can be parallel to each other, that is, are parallel to each other between two installation surfaces of spring 5, so that spring 5 has a better installation environment, and excessive bending deformation of spring 5 when elastic deformation occurs is avoided, and further spring 5 has a longer service life.

Referring to fig. 3 and 4, the abutting plate 412 is connected to a surface of the connecting plate 411 away from the guide groove 421, and the abutting plate 412 has an abutting surface 4121, the abutting surface 4121 is used for abutting against the ground pin 61, further, for a portion on the abutting surface 4121, the farther away from the connecting plate 411, the smaller the distance between the corresponding portion on the abutting surface 4121 and the aperture plate 31 is, that is, the abutting surface 4121 is inclined with respect to the aperture plate 31, and the abutting surface 4121 is disposed at an acute angle with respect to the aperture plate 31 along the extending direction away from the connecting plate 411. The abutment surface 4121 is provided such that when the ground pin 61 abuts the abutment surface 4121, the abutment surface 4121 more easily carries the shutter 4 along the guiding direction L.

It can be understood that, when the shielding portion 43 shields the live wire opening 312 and the neutral wire opening 313, the spring 5 may be in a natural state or a compressed state at this time, when the spring 5 is in the natural state, the spring 5 does not have elastic potential energy at this time, in the process that the ground pin 61 abuts against the abutting portion 41, the abutting portion 41 drives the spring 5 to generate elastic deformation under the acting force applied by the ground pin 61, which can be obtained according to hooke's law, the smaller the deformation amount of the spring 5 is, the smaller the elastic potential energy of the spring 5 is, because the spring 5 deforms naturally, the spring 5 has smaller elastic potential energy at this time, the ground pin 61 only needs to apply a smaller acting force to the abutting portion 41 to insert the ground pin 61 into the ground wire opening 311, and further, the three-hole plug 6 is easier to be inserted into the three-hole socket 7.

When the spring 5 is in a compressed state, the two slide rails 33 can be set at positions that can limit the position of the shielding element 4, that is, when the spring 5 is in a compressed state, because the spring 5 has elastic potential energy, the spring 5 will drive the abutting portion 41 to perform a return motion, so as to prevent the abutting portion 41 from blocking the ground wire opening 311 and being abutted against the ground wire pin 61 when the spring 5 is in a return state, thereby preventing the socket protection door 2 from being opened, in order to avoid this phenomenon, the slide rails 33 of the embodiment can limit the movement of the shielding element 4, in the process that the spring 5 drives the abutting portion 41 to return, the slide rails 33 can be abutted against the shielding portions 43, so that the spring 5 cannot drive the abutting portion 41 to continue the return motion, further, when the slide rails 33 are abutted against the shielding portions 43, the positions of the slide rails 33 can enable the abutting portion 41 to block the ground wire opening 311 and be abutted against the ground wire pin 61 of the three-hole plug 6, thereby achieving normal opening and closing of the socket protection door 2.

It can be understood that, by matching the slide rail 33 with the first guide rail 32, the first limiting plate 422 can be clamped between the first guide rail 32 and the slide rail 33, so that the first guide rail 32 and the slide rail 33 have a better guiding effect on the shielding member 4.

As shown in fig. 3, further, the fixing member 3 further includes a fastening portion 34, the fastening portion 34 is disposed at one end of the slide rail 33 far away from the opening plate 31, and abuts against the surface of the first limiting plate 422 far away from the opening plate 31, so as to prevent the shielding member 4 from moving in a direction away from the opening plate 31, and further enable the shielding member 4 to be in sliding fit with the opening plate 31, so as to ensure the opening and closing stability of the socket protection door 2.
