The shape of the second through hole 22 is determined according to the shape of the plug bush blocked by the protection door 2, for example, when the plug bush is a two-pole plug bush, the second through hole 22 is in a long strip shape, and the length direction of the second through hole is consistent with the length direction of the socket jack; when the insert sleeve is a three-pole insert sleeve, the second via hole 22 is in the shape of an oblique bar, and the oblique direction of the second via hole is consistent with the oblique direction of the insert sleeve.

Fig. 4 is a schematic state diagram of an exemplary socket protection structure according to an embodiment of the present invention, in which an upper portion shows that a protection door is in an initial state, and a lower portion shows that the protection door is in a retracted state; as shown in fig. 4, when the protective door 2 is in the initial state, the second via hole 22 on the panel 201 and the two first via holes 11 on the supporting base 1 are arranged in a staggered manner, so that other portions of the panel 201 can block the two first via holes 11. When the protective door 2 moves from the initial state to the avoidance state, the second via hole 22 on the protective door 2 can be correspondingly communicated with one of the two first via holes 11 (the first via hole 11 is referred to as a first via hole 11); since the shutter 2 moves from the first position to the second position on the support base 1 when the shutter 2 moves from the initial state to the retracted state, and accordingly, the shutter 2 is disposed at the first position on the support base 1 (the other first via 11 is referred to as the second first via 11 here), so that the shutter 2 can block the second first via 11 at the first position, and when the shutter 2 moves to the second position, the second first via 11 at the first position is exposed by the exit of the shutter 2. Therefore, when the protective door 2 is in the avoiding state, the first via hole 11 is correspondingly communicated with the second via hole 22 on the protective door 2 to realize exposure, and the second first via hole 11 is exposed due to the exit of the protective door 2, so that both the first via holes 11 are exposed to facilitate the insertion of the plug.

In some possible implementations, as shown in fig. 2, the frame 202 of the protection door 2 includes: the side frame 2021 and the panel frame 2022, the side frame 2021 is movably connected with the supporting base 1, the panel frame 2022 is located inside the side frame 2021, two avoiding grooves 2023 are arranged on the bottom wall of the panel frame 2022, and the two avoiding grooves 2023 are in one-to-one correspondence with the two guide blocks 5; the escape groove 2023 receives at least the top of the guide block 5 when the protective door 2 moves in the second direction.

The avoiding groove 2023 is located on the surface of the panel frame 2022 facing the guide block 5, and the design of the avoiding groove 2023 is favorable for reducing the thickness of the protective door 2 and further the thickness of the socket, for example, the thickness of the external panel 201 of the socket is less than or equal to 4mm, which also reduces the manufacturing cost of the socket.

In some examples, the escape groove 2023 can receive not only the top of the guide block 5 (because the top of the guide block 5 corresponds to the maximum height of the guide block 5) when the protective door 2 moves in the second direction, but further, the escape groove 2023 can receive the entire guide block 5. In this way, the structure of the escape groove 2023 can be made the same as that of the guide block 5, so that the guide block 5 can be fitted snugly into the escape groove 2023.

Wherein, for any two side parts with connection relation, an included angle is formed between the two side parts, and the included angle can be 90 degrees or less than 90 degrees.

For example, the frame 202 of the protection door 2 corresponding to the two-pole socket may have a rectangular shape, and the frame 202 of the protection door 2 corresponding to the three-pole socket may have a rectangular shape or a trapezoidal shape.

The panel 201 is adapted to the frame 202, and the panel 201 is fixed to the top of the frame 202 in a detachable connection manner, for example, the top of the frame 202 has a slot, and the bottom of the panel 201 has an insertion block, so that the insertion block is inserted into the slot, thereby fixing the panel 201 to the frame 202.

In some possible implementation manners, an embodiment of the present invention provides a socket protection door structure, further including: the two outer guide shafts 4, the two outer guide shafts 4 are respectively located outside two side walls of the frame 202 of the protection door 2 extending along the second direction, that is, the two side wall sections extending along the second direction are respectively provided with the guide grooves 103.

Illustratively, as shown in fig. 2, the outer guide shafts 4 and the inner guide shafts 9 are respectively located outside and inside the side wall of the frame 202, and the outer guide shafts 4 and the inner guide shafts 9 located on the same side can be opposite to each other, which is not only beneficial to manufacturing, but also beneficial to improving the strength of the protection door 2.

The side wall portions 102 have guide grooves 103 on both side walls extending in the second direction, respectively, and the guide grooves 103 receive the outer guide shaft 4 and guide the movement of the outer guide shaft 4 in the first direction and the second direction.

Illustratively, the outer guide shafts 4 are cylindrical bodies, and both the outer guide shafts 4 are located at the middle positions outside the side walls of the frame body 202, so that both sides of the protective door 2 located on the outer guide shafts 4 are symmetrically arranged, so that the protective door 2 can move with the outer guide shafts 4 as the center of motion.

The two guide grooves 103 correspond to the two outer guide shafts 4 one to one, the outer guide shafts 4 penetrate through the corresponding guide grooves 103, and the guide grooves 103 can guide the movement of the outer guide shafts 4 in the first direction and the second direction, that is, the guide grooves 103 at least comprise groove cavities distributed along the first direction and distributed along the second direction.

Illustratively, as shown in fig. 6, the guide groove 103 includes: the guide section 1031, spacing section 1032, first guide section 1033 and second guide section 1034 that communicate in order all extend along the first direction, and the guide section 1031, spacing section 1032, first guide section 1033 extend along the second direction.

The guiding section 1031 is used for guiding the outer guide shaft 4 to enter the limiting section 1032; the limiting section 1032 is used for limiting the outer guide shaft 4 in the first guide section 1033; the first guide section 1033 is for guiding the movement of the outer guide shaft 4 in the first direction; the second guide section 1034 serves to guide the movement of the outer guide shaft 4 in the second direction.

During application, the outer guide shaft 4 is assembled under the guide of the guide section 1031, enters the first guide section 1033 through the limiting section 1032, and when the protective door 2 is in an initial state, the limit of the limited section 1032 of the outer guide shaft 4 is always positioned in the first guide section 1033. When the protective door 2 is moved by the latch, it enters the second guide section 1034 through the first guide section 1033, thereby realizing the movement of the protective door 2 in the first direction and the second direction.

With this guide groove 103, it is possible to guide not only the outer guide shaft 4 to move sequentially along the first guide section 1033 and the second guide section 1034 but also the outer guide shaft 4 to move sequentially along the second guide section 1034 and the first guide section 1033.

The guiding section 1031, the limiting section 1032, the first guiding section 1033 and the second guiding section 1034 all have two side walls opposite to each other at intervals, and the two side walls are respectively provided by the side walls of the side wall portions 102 on the supporting seat 1 at two sides of the guiding groove 103.

In some examples, as shown in fig. 6, the second pilot segment 1034 includes: a first sidewall 10341 and a second sidewall 10342 arranged at an interval; the first side wall 10341 extends in a first direction (that is, the first side wall 10341 is vertically disposed in an up-down direction); the second side wall 10342 is obliquely disposed and extends along the second direction (that is, the second side wall 10342 is obliquely disposed along the left-right direction), and an interval between a top end of the second side wall 10342 and the first side wall 10341 is smaller than an interval between a bottom end of the second side wall 10342 and the first side wall 10341.

In the embodiment of the present invention, the second sidewall 10342 may be located on the right side of the first sidewall 10341, so that the protection door 2 moves right when moving to the avoiding state, and the second sidewall 10342 may also be located on the left side of the first sidewall 10341, so that the protection door 2 moves left when moving to the avoiding state.

When the guidance door moves from the initial state to the avoidance state, or moves from the avoidance state to the initial state again, the second guidance section 1034 can provide the guidance door with a movement in the second direction, and in the process, the second side wall 10342 of the second guidance section 1034 can contact with the outer guide shaft 4 to guide the movement of the outer guide shaft 4, which is beneficial to promoting the movement of the guidance door, so that the movement of the protection door 2 is smoother.

In some examples, before the outer guide shaft 4 of the protective door 2 enters the second guide section 1034, the inner guide shaft 9 is first brought into contact with the guide surface 51 of the guide block 5, so that the inner guide shaft 9 performs a second-direction movement along the guide surface 51 to facilitate the movement of the protective door 2. Further, in this process, at least the top portion of the guide block 5 is caused to enter the escape groove 2023.

In some examples, when the protective door 2 is moved to the reset position, the outer guide shaft 4 is brought into contact with the second side wall 10342 of the second guide section 1034 to guide the reset movement of the outer guide shaft 4 in the second direction, and the guide surface 51 of the guide block 5 is no longer in contact with the inner guide shaft 9. It can be seen that the cooperation of the inner guide shaft 9 and the guide block 5 promotes the movement of the protection door 2 from the first direction to the second direction, and the cooperation of the outer guide shaft 4 and the second guide section 1034 promotes the reset movement of the protection door 2 from the second direction to the first direction, which is more beneficial to improving the service life of the protection door 2.

In particular, the dislocation arrangement of the guide groove 103 and the bottom supporting part 101 is combined, so that the stress point of the protective door 2 moving to the avoiding state is more inclined to the bottom supporting part 101 of the supporting seat 1, the stress of the outer guide shaft 4 is dispersed, the requirement on the structural rigidity of the protective door 2 is reduced, the matching of the outer guide shaft 4 and the guide groove 103 is easier, the deformation is not easy to occur, and the service life of the protective door structure of the socket is prolonged.

In addition, the mode of transferring the stress point to the bottom supporting part 101 of the supporting seat 1 is also beneficial to reducing the thickness of the protective door 2, so that the maximum thickness of the decorative panel of the socket can be less than or equal to 4mm when the space with the reduced thickness of the protective door 2 is correspondingly transferred to the socket on the premise that the plug contact plug bush meets the national standard of H1.

First direction section 1033 extends along the upper and lower direction, second direction section 1034 extends along the left and right direction, in order to form L type direction section, utilize this L type direction section limitation outer guiding axle 4, outer guiding axle 4 can oblique slip effectively in this L type direction section, this can not only reduce shutter 2 sliding stroke, reduce frictional resistance, still reduced and inserted the action requirement to the user, it is wider to making to require the adaptability to insert the action, make the plug light to insert, obtain light and insert and feel, user experience has been avoided producing the card and has been felt.

In addition, through the matching driving mode of the outer guide shaft 4 and the L-shaped guide section, the technical problem of abrasion of a plug to a driving surface can be avoided, the requirement on the material property of the protective door 2 is reduced, and the cost is favorably reduced.

Combine the utility model discloses socket shutter structure that the embodiment provided carries out the exemplary description to the normal process of opening of shutter 2:

as shown in fig. 5-7, when the protection door 2 is normally opened, two pins M are required to be inserted into the N-pole insertion hole and the L-pole insertion hole respectively, under the thrust of the two pins M, the outer guide shaft 4 of the protection door 2 first moves in the first guide section 1033 along the first direction until the outer guide shaft 4 enters the second guide section 1034 to move along the second direction, and the protection door 2 moves to an avoidance state, so that the two first through holes 11 on the support base 1 are exposed, and the two pins M are correspondingly inserted into the corresponding first through holes 11 and finally inserted into the corresponding insertion sleeves (see fig. 8). As shown in fig. 8, in the retracted state, the side wall of the frame 202 of the protective door 2 abuts against the side wall of one of the plugs M, and the side wall of the second via hole 22 of the protective door 2 abuts against the side wall of the other plug M.

For the reset process of the protective door 2, firstly, the two pins M are withdrawn from the plug bush, then, the compressed elastic reset piece 3 drives the protective door 2 to reset, so that the outer guide shaft 4 firstly slides along the second guide section 1034 until entering the first guide section 1033 and being limited by the limit section 1032, and finally, the protective door 2 is reset to the initial state. In the initial state, the elastic restoring member 3 pushes the protection door 2 so that the top surface 21 of the protection door 2 closely fits the jack.

The embodiment of the utility model provides a socket shutter structure, shutter 2's the aforesaid is along the slip of first direction and second direction, and occupation space is little (small), and the slip stroke is little, does benefit to the structure of simplifying this socket shutter structure, reduces part quantity (materials reduction), realizes that the component part quantifies fewly, has retrencied shutter 2 assembly process, the cost is reduced. In the correlation technique, five hole sockets include 14 spare parts at least, and utilized the utility model provides a five hole sockets of socket shutter structure can only 9 spare parts, have that the product function is many, spare part product is few, easily carry out automated production's advantage.

In some examples, the angle between the second sidewall 10342 and the first direction is greater than or equal to 17 ° and less than or equal to 90 °, for example, can be 25 °, 27 °, 30 °, 35 °, and the like, within which the movement of the protection door 2 is facilitated to be smoother.

In some examples, the length of the second sidewall 10342 is greater than 0 and less than or equal to 2.6mm, such as 1mm, 1.5mm, 2mm, 2.5mm, etc., and the length of the second sidewall 10342 actually represents the sliding stroke of the protective door 2, and the sliding stroke is defined as above, so that the movement of the protective door 2 is more smooth.

Particularly, the included angle between the second sidewall 10342 and the first direction is not less than 27 ° and not more than 90 °, and the sliding stroke of the protection door 2 is not more than 2.6mm, so that the sliding process of the protection door 2 can be smoother, the stuck feeling can be avoided, the service life of the protection door 2 can be prolonged under the condition, and the sliding reset life of the protection door 2 can be ensured to reach 4 ten thousand times at least, which is higher than the national standard.

With respect to the above-described range of the angle of inclination of the second side wall 10342 of the second guide section 1034, it can be determined in the following manner:

during the reset movement of the protective door 2, the outer guide shaft 4 first slides along the second guide section 1034, i.e., the outer guide shaft 4 contacts the second side wall 10342 of the second guide section 1034 and generates friction. Moreover, because the supporting seat 1 of the socket is generally prepared by using polycarbonate which is a national standard material, the friction coefficient μ of the polycarbonate is 0.25-0.35, and the following calculation formula is adopted: f_Bulletsinθ-μF_{Press and press}When the elastic force overcomes the friction force, the protective door 2 can be reset, and the acting force is equal to the reaction force according to the Newton's third law formula, namely F_{Press and press}＝F_Bulletcos θ, the angle θ between the second sidewall 10342 and the first direction is calculated to be > 17 °, i.e., 17 ° as a boundary value.

Further, considering that the protective door 2 may cause uneven slope surfaces to cause resistance during long-term sliding friction, the included angle between the second sidewall 10342 and the first direction may be increased, for example, to 25 °, 27 °, 30 °, 35 °, and so on, which may promote better reset of the protective door 2 during long-term sliding.

The embodiment of the present invention provides an embodiment, the bottom of the side wall portion 102 where the second guiding section 1034 is located can be directly connected to the bottom supporting portion 101, as shown in fig. 6, the bottom of the side wall portion 102 where the second guiding section 1034 is located can also be set in a suspension manner, that is, the guiding groove 103 and the bottom supporting portion 101 are arranged in a dislocation manner in the third direction, wherein the third direction is the direction perpendicular to the second direction, wherein the side wall of the side wall portion 102 where the second guiding section 1034 is located is close to the outside, the bottom of the side wall portion is suspended, and the bottom supporting portion 101 is closer to the inside.

The interval between the third and

fourth sidewalls

10321 and 10322 is gradually increased in a direction approaching the first guide section 1033, and the minimum interval between the third and

fourth sidewalls

fourth sidewalls

10321 and 10322 gradually decreases to a minimum and then gradually increases from the minimum to the minimum along the direction approaching the first guide section 1033.

Thus, after the outer guide shaft 4 is forced to enter the limiting section 1032 under the action of an external force, the outer guide shaft 4 is limited by the minimum distance between the third side wall 10321 and the fourth side wall 10322, so that the outer guide shaft 4 cannot be freely separated from the limiting section 1032, the effective limiting of the limiting section 1032 on the outer guide shaft 4 is realized, and the initial state of the protective door 2 is favorably maintained, and the assembly efficiency of the protective door 2 is favorably improved.

sixth side walls

10331 and 10332, are always the same, and the fifth and

sixth side walls

10331 and 10332 extend in the first direction, so that the outer guide shaft 4 moves in the first direction in the first guide section 1033.

In particular, the seventh and

eighth side walls

10311 and 10312 are each disposed obliquely, the distance between the top end of the seventh side wall 10311 and the top end of the eighth side wall 10312 is greater than the distance between the bottom end of the seventh side wall 10311 and the bottom end of the eighth side wall 10312, and the distance between the top end of the seventh side wall 10311 and the top end of the eighth side wall 10312 is also greater than the outer diameter of the outer guide shaft 4, so that the outer guide shaft 4 can easily enter the guide section 1031 for guiding the fitting of the protection door 2 into the support base 1.

In the socket protection door structure provided by the embodiment of the present invention, the seventh side wall 10311, the third side wall 10321, the fifth side wall 10331, and the first side wall 10341 are connected in sequence and are integrally formed; the eighth side wall 10312, the fourth side wall 10322, the sixth side wall 10332, and the second side wall 10342 are connected in sequence and are integrally formed.
