Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of socket protection door, and particularly relates to a protection door assembly with an isolation structure. BACKGROUND

[0002] A socket, also known as a power socket or a switch socket, is a socket with one or more electrical circuits into which a plug can be inserted. This allows the connection of various wires. This facilitates the connection with other circuits. The connection and disconnection between the line and the copper piece achieve the connection and disconnection of the circuit.

[0003] Sockets are divided into various types according to their installation and use, such as extension sockets, ground sockets and wall sockets. Regardless of the types, they all have common structures, including a shell, a socket, internal metal conductors and a connection structure for connecting external lines. The socket hole has special adaptation requirements for the shape of the connector pin. However, regardless of the type of connector, the existing socket hole is designed as an open structure, and the opening size is slightly larger than the inserted pin, which is limited and clamped by the internal structure.

[0004] Generally, a socket has a protection door / safety door structure inside the socket hole to form a blockage inside the socket hole opening to prevent a single conductor from being mistakenly inserted into the position of the live line / fire line, thereby causing a safety accident. The existing protection door structure is usually a linkage structure, that is, the two socket holes of the live line / fire line share an integrated protection door structure. The protection door structure has two movement modes, that is, when a plug is normally inserted into the socket hole, the pins of the plug simultaneously act on the protection door structure to push it to displace in a direction to avoid space, at which time the pins can be smoothly inserted into the socket interior to be connected with the conductors; the other movement mode is that when a single conductor is inserted, the protection mechanism of the protection door structure is triggered to be locked and limited to avoid, thereby achieving the protection effect.

[0005] In some sockets with waterproof requirements, in addition to the separately arranged sealing structure, the two spaces of the live line and the fire line need to be independently separated, that is, after the liquid that breaks through the sealing structure from the socket hole enters the interior of the socket, direct liquid conduction short circuit can also be avoided. However, since the protection door structure is usually designed as an integrated structure, it cannot be adapted to the structure design of the independent space, and therefore the protection door structure needs to be optimized and adapted. SUMMARY

[0006] In order to solve the problems existing in the prior art, the application provides a protection door assembly with an isolation structure, which is an independent structure or part of a socket, can form at least two independent compartments at the socket hole, and can ensure the linkage of the protection door structure while maintaining the sealing effect between the compartments through structure optimization in the interior.

[0007] The technical scheme adopted by the application is as follows:

[0008] In a first aspect, the present application provides a protective door assembly with a shielding structure, which is part of or arranged on a socket to shield the socket port, comprising a shell, the shell having at least two compartments separated by a blocking piece arranged therein, each compartment having a passage for an external conductor to pass through and enter the socket for conduction;

[0009] The shell has a protective door structure that blocks the passage, and the protective door structure comprises parts in all the compartments, and all the parts of the protective door structure are connected in linkage through the blocking piece or are connected to the blocking piece in linkage through the blocking piece.

[0010] It should be noted that the protective door assembly can be arranged in or out of the socket as an independent structure, or it can be a specific internal part of the socket that bears the corresponding function area, and the shell refers to a structure that has a separation effect between this part and other parts, while also fixing and limiting the internal components of the protective door assembly.

[0011] The shell has a certain space, which is separated into several independent compartments by the blocking piece, and the so-called passage refers to a passage for a conductor to pass through in each compartment, and the passages of different compartments are independent, which can avoid the problem of short circuit caused by the entering of conductive medium in the conductors in different compartments.

[0012] The so-called linkage refers to the parts of the protective door structure in different compartments, which can transmit force to all parts of the protective door structure under the action of any external force, and then form a movement trend in combination with the connection state of the internal structure of the shell and the protective door structure, and in combination with the usual design of the existing protective door structure, it can play the corresponding function of the original protective door structure under the premise of forming at least two relatively closed compartments.

[0013] In combination with the first aspect, the present application provides a first embodiment of the first aspect, wherein the blocking piece has a deformation part connected with the protective door structure, and the deformation part has a reset movement trend when the deformation part is deformed by the displacement of the protective door structure driven by the external conductor.

[0014] It should be noted that the so-called reset movement trend refers to the protective door structure in a limited connection state in the shell, i.e. the deformation part of the blocking piece is elastically connected with the shell, and after being subjected to an external force, it will be subjected to a pulling force of the blocking piece, thereby replacing the existing elastic member or magnetic member through the blocking piece. The protective door structure has two movement positions, i.e. shielding or not shielding the passage, and if subjected to a pushing force of the plug, it will move to one side to avoid the passage for the plug to pass through the passage, and if only the part of the protective door structure in the single compartment is subjected to a pushing force or is not subjected to an external force, the protective door structure is locked with the shell in a state of shielding the passage.

[0015] With the first aspect, the application provides a second embodiment of the first aspect, wherein the blocking piece has a ring-shaped fixed part, and the fixed part is connected to the inner wall of the shell to isolate the storage bin.

[0016] With the second embodiment of the first aspect, the application provides a third embodiment of the first aspect, wherein the inner wall of the shell is provided with a mounting groove, and the edge of the fixed part is inserted into the mounting groove to be connected.

[0017] With the second embodiment of the first aspect, the application provides a fourth embodiment of the first aspect, wherein the blocking piece is an integrated structure formed by the inner wall of the shell extending and converging towards the internal space to wrap the protection door structure in a ring shape.

[0018] With the second embodiment of the first aspect, the application provides a fifth embodiment of the first aspect, wherein the shell has at least one ring-shaped cut, and the shell is divided into a sub-part with an independent storage bin by the ring-shaped cut.

[0019] The blocking piece is an elastic partition plate, the sub-part is formed on the surface of the fixed part of the elastic partition plate to form the shell, and the protection door structure is connected to the side of the elastic partition plate or passes through the elastic partition plate inside the shell.

[0020] With the first aspect, the application provides a sixth embodiment of the first aspect, wherein the blocking piece is a structure movably connected to the inner wall of the shell, and the protection door structure is fixedly connected to the blocking piece and moves with the blocking piece.

[0021] With the first aspect or the several embodiments of the first aspect, the application provides a seventh embodiment of the first aspect, wherein the shell comprises a face cover and a box body that are buckled and sealedly connected to each other, and the protection door structure is arranged in the box body.

[0022] With the first aspect or the several embodiments of the first aspect, the application provides an eighth embodiment of the first aspect, wherein the inner wall of the shell is provided with a protruding rib, and the protection door structure is formed as a fulcrum to be stressed and pried in the shell by the protruding rib.

[0023] The single channel has two openings of a jack and a bottom hole on the shell, and the part of the protection door structure corresponding to any channel has at least one clamping block matched with the jack or the bottom hole to be pried and clamped.

[0024] With the first aspect or the several embodiments of the first aspect, the application provides a ninth embodiment of the first aspect, wherein the shell is internally provided with an elastic member or a magnetic member to provide a restoring force for the protection door structure.

[0025] The application has the following beneficial effects:

[0026] (1) the present application optimizes the structure in the shell, and separates the shell into independent bins through the cooperation of the blocking piece and the protection door structure, that is, the separation of the zero line / fire line is met, and the linkage of the protection door structure is realized under the premise of ensuring the sealing effect;

[0027] (2) the present application optimizes the connection of the blocking piece and the protection door assembly and the linkage mode of the protection door assembly, so that the above two technical effects are realized under the original volume of the original protection door assembly, thereby saving materials and reducing costs.

[0050] Embodiment 1:

[0051] The present embodiment discloses a protective door assembly with an isolation structure, which serves as a part of the socket to shield the socket jack 4.

[0052] It should be noted that the existing socket protective door assembly as a conventional design includes a space and a movable member in the space, which is the protective door structure 5. The socket with two or three outlets in the space is provided with two or three passages, and the passages are provided for the external conductor to pass through and contact with the conductor in the socket.

[0053] Among them, the protective door structure 5 has integrity in the space, that is, whether the structure is designed in an integral or split structure, it is in an integral linkage mode, which has the effect of force transmission and motion transmission. At the same time, the existing protective door structure 5 has various shape designs, and only needs to have a part inside the shell to block the passage.

[0054] At the same time, since the protective door structure 5 has integrity, after it is forced to move, the avoidance space generated is the empty space formed by the opening or bending of the protective door structure 5 itself, and after the forced movement, the empty space formed by the opening or bending is just at the passage, thereby achieving the avoidance effect.

[0055] The protective door structure 5 in the embodiment is of a conventional design, that is, has a plurality of through holes 10 corresponding to passages, and when the conductor is inserted from the corresponding passage, if the normal trigger causes the protective door structure 5 to displace, the through hole 10 will enter the corresponding passage to form a communication state. In order to facilitate movement, a guide slope 11 is arranged at the through hole 10, and when the end of the vertically inserted conductor contacts the guide slope 11, a horizontal component force is generated, so that the protective door structure 5 displaces to generate an avoidance space.

[0056] An elastic or magnetic body is further arranged in the shell to provide a restoring force to the protective door structure 5, so that the protective door structure 5 maintains the effect of blocking the passage under the action of no external force. The shell is designed to have a limiting structure in the horizontal direction to limit the excessive displacement of the protective door structure 5 under the driving of the elastic or magnetic body to affect the blocking effect.

[0057] The protective door assembly of the embodiment is an optimized improvement on the structure of the prior art, and realizes the sealing function on the premise of retaining the original function of the protective door structure 5.

[0058] Specifically, the protective door assembly includes a shell and a protective door structure 5 arranged in the shell, and a blocking piece 6 is further arranged in the shell to divide the space inside the shell into at least two compartments, each compartment has a passage, and each passage has a plurality of openings on the shell for the external conductor to pass through. The protective door structure 5 includes a plurality of parts in different compartments, all the parts of the protective door structure 5 are connected through the blocking piece 6, and the parts of the protective door structure 5 are in linkage relationship.

[0059] Further, the shell is a full-enclosing structure, which is suitable for a two-plug or three-plug socket, and the three-plug socket only protects two plug holes 4 connected with the zero line and the live line, and the related linkage structure can be arranged at the ground wire to cooperate with the protective door structure 5 to realize pushing, or the protective door structure 5 is only arranged at the zero line and the live line to be forced to move.

[0060] The shell has a rectangular space, and the blocking piece 6 is arranged at the center line. The blocking piece 6 has an annular outer edge, and the annular outer edge is attached to the inner wall of the shell to divide the rectangular space into two compartments. In this embodiment, each compartment has two openings, and the connecting line of the openings is the passage.

[0061] The two ends of the protection door structure 5 corresponding to the two openings are respectively provided with one or two clamping blocks. When the protection door structure 5 is forced to move downward on one side and the other side is raised, the clamping blocks on the forced side fall and jointly act on the clamping blocks on the raised side to clamp the edges of the openings on the corresponding side to form a horizontal restriction. At this time, even if the guide slope 11 of the protection door structure 5 on one side is forced to generate a horizontal thrust, the clamping blocks and the edges of the openings can be locked and positioned through the clamping cooperation.

[0062] Further, the blocking piece 6 includes a fixed part and a deformation part, including a mode of being made of an elastic material as a whole and a mode of being made of an elastic material as an integral structure. The fixed part only refers to the annular area connected with the inner wall of the shell. The deformation part can deform under stress and generate a restoring force to return to the original position by adopting a soft elastic material. The protection door structure 5 has two parts, which are respectively arranged on both sides of the blocking piece 6 and connected with the blocking piece 6. When stressed, the blocking piece 6 is partially displaced, and the deformation part of the blocking piece 6 realizes the relative displacement between the connection part of the protection door structure 5 and the fixed part connected with the shell through tensile deformation.

[0063] Among them, the blocking piece 6 is a plate or block structure with uniform thickness. The protection door structure 5 can be supported by the blocking piece 6 through connection with the blocking piece 6, or a protruding structure in the shell is arranged to contact the protection door structure 5 for support, or the blocking piece 6 supports the protection door structure 5 together.

[0064] The contact part of the protection door structure 5 and the blocking piece 6 can be directly set as a deformation part for overall deformation, or the contact part is a hard structure, and the fixed part is also a hard structure, only an annular deformation part is arranged around the contact part, and the same technical effect is also achieved. The protection door structure 5 or passes through the blocking piece 6 to form an integral linkage structure, or is connected on the blocking piece 6 to form a linkage structure through the blocking piece 6.

[0065] In some embodiments, the stop 6 consists of three parts: a first fixing member in the middle, an elastic ring arranged around the first fixing member, and a second fixing member fixed to the inner wall of the housing. Both the first and second fixing members have annular grooves to hold the elastic ring between them. The elastic ring is made of rubber or silicone material and has good elongation properties. The first fixing member forms a protruding connecting member, such as a stud or hook, on each side of the compartment. The protective door structure 5 is divided into two independent parts and has a connecting structure adapted to the connecting member, which can be directly installed on the first fixing member of the stop 6. Meanwhile, the protective door structure 5 is supported by the raised ribs at the bottom of the housing. Since the first fixing member is a rigid structure, it can be detachably connected with the protective door structures 5 on both sides to form a fixed integrated linkage structure. That is, when one side is subjected to force, the whole is subjected to force and linkage. If only one side is subjected to force, only one side will fall and the other side will rise due to the influence of the ribs. With the limited structure provided, it cannot avoid the effective space. At this time, the conductor inserted on one side cannot enter the socket through the channel. When both sides are subjected to force, the guide slope 11 provided on the protective door structure 5 guides it to slide to one side to form an avoidance space. At this time, the conductors on both sides can smoothly enter the socket and connect with the neutral / live wire.

[0066] In some embodiments, the stop 6 is a sliding structure within the housing. Specifically, several grooves are provided within the housing, and the stop 6 is a rigid structure with sliders extending into the grooves. The edge of the stop 6 contacts and abuts against the inner wall of the housing, and a sealing element is provided at its gap for sealing. The stop 6 has a rotatable rod in the middle, with a connecting end at each end of the rod, connecting to two parts of the protective door structure 5 respectively. This allows the protective door structure 5 and the stop 6 to be rotatably connected, enabling it to not only tilt and lock when force is applied to one side of the protective door structure 5, but also to slide to one side to create a passage for the conductor when force is applied to both sides.

[0067] In some embodiments, such as Figures 1-12 As shown in the figure, another implementation of the stop 6 and the housing is illustrated.

[0068] The shell has an annular cut along its vertical centerline, dividing it into two sub-sections. The outer surfaces of the two sub-sections are symmetrically arranged, and each sub-section has a socket 4 at the top and a bottom hole 7 at the bottom. The socket 4 and the bottom hole 7 are vertically aligned, forming a through channel with the internal space.

[0069] An integral elastic partition 3 is provided at the annular cut in the middle of the shell as a stop 6. The elastic partition 3 is a plate structure, and its annular edge is exposed outside the shell. The shell and the stop 6 are integrated into a single structure by means of adhesive or other methods.

[0070] exist Figures 1-5 The image shows a protective door assembly adapted to a two-prong socket, while Figure 6 andFigure 7 The protective door assembly adapted to three-prong sockets is shown. The solution adapted to two-prong and three-prong sockets is based on a similar principle, only with adjustments made to accommodate the different relative positions of the prongs of three-prong and two-prong sockets.

[0071] from Figure 3 As can be seen, when there is no force, the elastic partition 3 is located in the middle of the shell and fills the gap between the two compartments, so that objects entering the compartment from one side cannot come into contact with objects in the other compartment, thereby preventing the incoming liquid from connecting the conductors in the two compartments and forming a short circuit.

[0072] Two protruding blocks are provided on the inner wall of the housing. The blocks contact the protective door structure 5 in different compartments to restrict its movement to the right in the figure, while there is space on the left side, so that the protective door structure 5 can be moved to the left in the figure after being subjected to force, so that the through hole 10 on the protective door structure 5 is aligned and connected with the corresponding channel.

[0073] exist Figure 5 As can be seen, under stress, the elastic partition 3, made of homogeneous elastic material, will undergo tensile deformation in the upper and lower suspended areas. Since there are certain gaps between the upper and lower parts of the protective door structure 5 and the shell, the lower gap is held in place by protruding ribs to form a "seesaw" state. The gap formed can avoid the formation of large shear stress on the elastic partition 3, which would cause damage to the elastic partition 3.

[0074] exist Figures 10-12 As can be seen, the protective door structure 5 is an integrated design. The elastic partition 3 has a connecting hole 1210 in the middle, through which the middle part of the protective door structure 5 passes. The elastic partition 3 is a structure fitted into an annular mounting groove in the middle of the protective door. The protective door structure 5 has an upper locking block 8 and a lower locking block 9 on each side, which together form a good unilateral force-bearing locking and limiting effect.

[0075] exist Figures 6-9 As can be seen, the protective door structure 5 consists of two parts, which are respectively attached to both sides of the elastic partition 3.

[0076] Furthermore, such as Figure 13 and Figure 14 As shown, in order to improve the reset effect of the protective door structure 5, a spring 13 is provided in the empty position on the left side inside the housing. The spring 13 always provides a pushing force to the right of the protective door structure 5.

[0077] Furthermore, the housing is composed of a cover 1 and a box body 2 that are interlocked, and a sealing ring structure is provided at the gaps for sealing.

[0078] This invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products based on the inspiration of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention; the scope of protection of this invention should be determined by the claims, and the specification can be used to interpret the claims.
