Description

Technical Field

[0001] The present invention relates to the technical field of socket equipment, and in particular to a ground socket. Background Art

[0002] The floor socket is abbreviated as the ground socket. It is installed on the ground or similar places and is used to connect to fixed wiring. It is usually used as the terminal and outlet of the ground wiring system. It has a movable body that can be flipped out of the ground. It is easy to use and is widely used in large indoor places such as offices, airports, hotels, shopping malls, and homes.

[0003] The existing ground sockets on the market mainly include a metal shell, a socket body and a pop-up mechanism arranged between the metal shell and the socket body, as well as a power conductor assembly and a terminal assembly arranged in the socket body. A socket panel with a plurality of jack structures is arranged on the socket body, and the power conductor is connected to the terminal assembly to provide power to the ground socket. The socket body can be flipped on the metal shell through the pop-up mechanism. When in use, it flips out of the installation ground where the metal shell is located, so that one side of the socket panel faces outward, and when not in use, the socket panel will be flipped and buried in the ground trough. Moreover, the existing ground sockets generally do not have a leakage protection function. Therefore, people can only install a leakage protector in the ground trough in combination with the ground socket, but this not only increases the product volume and installation space, but also greatly increases the cost. The installation and wiring are cumbersome and inconvenient, and the safety is poor, so it is not applicable.

[0004] It can be seen from the above structure and working principle that the existing ground socket still has the following technical problems in actual use:

[0005] When not in use, the floor socket is buried in the ground trench, but it is electrified. Affected by the use environment and age, the floor socket may leak electricity, resulting in a potential difference. Existing floor sockets all use metal shells according to strength requirements. Therefore, in crowded places, when the human body is close to the floor socket, it is easy to cause step arcs and cause harm to the human body, especially when the floor socket is opened by hand, there will be a direct hazard of electric shock, posing a major safety hazard. Summary of the invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that when a ground socket is buried in a ground trench with power on and leakage occurs, it is easy to cause step arcs to cause harm to the human body, and direct contact with the ground socket may cause electric shock hazards, posing a safety hazard. The present invention thus provides a safe and reliable ground socket that can provide power-off protection when not in use to avoid leakage.

[0023] The elastic force of the second elastic member is greater than the elastic force of the first elastic member.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. In the floor socket provided by the present invention, an interlocking mechanism is arranged between the operating mechanism and the moving contact to play an interlocking cooperation role. When the interlocking mechanism is in a locked state, the operating mechanism and the moving contact form a linkage relationship to drive the moving contact to contact the static contact, and when the interlocking mechanism is in an unlocked state, the moving contact is disengaged from the operating mechanism and disconnected from the static contact under the action of the first elastic member, so that the circuit on-off operation of the floor socket can be realized. Therefore, the driving structure of the power-off driving device is arranged in linkage with the interlocking mechanism. When the floor socket is not in use, the socket body is rotated and closed in the base, so that the driving structure is pushed by the base and moves into the socket body, and then the interlocking mechanism is driven to move from the locked state to the unlocked state, which can trigger the disconnection action of the moving contact and the static contact, and realize the power-off isolation of the socket body, thereby avoiding the leakage of the floor socket buried in the ground groove. In addition, the power-off driving device can also be manually operated to realize rapid power-off protection when the floor socket is in use, so as to cope with emergency situations. The design is reasonable, the operation is convenient, and the electric shock hazard to people is effectively avoided. It is practical, safe and reliable.

[0026] 2. In the floor socket provided by the present invention, the interlocking mechanism includes a locking structure movably installed on the contact support, and the locking structure plays a role of linkage connection or linkage release between the operating mechanism and the contact support. Therefore, while the operating mechanism and the locking structure form a linkage relationship, the linkage cooperation between the operating mechanism and the contact support is also promoted, so that the operating mechanism drives the moving contact on the contact support to contact the static contact. Conversely, after the operating mechanism and the locking structure are released from the linkage relationship, the contact support is no longer restricted by the linkage of the operating mechanism, and the disconnection action of the moving and static contacts can be realized. The design is reasonable and the transmission is reliable.

[0027] 3. In the floor socket provided by the present invention, the movement directions of the operating rod and the locking structure are perpendicular, the outer periphery of the operating rod has a matching structure, and the locking structure has a locking portion matching with the matching structure along the second direction and a free portion allowing the operating rod to move freely. With this structural arrangement, when the operating rod contacts the locking portion, the position of the operating rod is limited by the matching structure and the locking portion, so that the operating rod and the locking structure form a linkage relationship; and when the operating rod contacts the free portion, its position is not constrained, that is, the operating rod and the locking structure are disengaged from the linkage, so that the contact support and the operating rod are separated and moved from each other under the action of the first elastic member and the second elastic member respectively, thereby realizing the disconnection action of the moving and static contacts.

[0028] 4. In the floor socket provided by the present invention, the bottom of the operating rod is provided with the matching groove and the cone arranged below the matching groove. The cone is used to facilitate the operating rod to pass through the locking hole more smoothly. When the operating rod is pressed down, the cone pushes one side of the locking hole to make way for the locking structure to move until the cone passes through the locking hole. Then, the locking structure drives one side of the locking hole to extend into the matching groove under the action of the third elastic member, thereby limiting the cone below the locking hole, thereby realizing the linkage cooperation between the locking structure and the operating rod.

[0029] 5. In the floor socket provided by the present invention, the leakage release mechanism has a driving end which drives the locking structure to move along the second direction to the free position when triggered. The advantage of such a configuration is that when leakage occurs, the locking mechanism is driven to an unlocked state by the leakage release mechanism, so that the operating rod and the contact support are disengaged from the linkage, thereby triggering the disconnection action of the moving contact and the static contact, thereby playing a role in leakage protection, and can cut off the leakage circuit in time to ensure the safety of the line. Therefore, the floor socket of the present invention has both leakage protection function and power-off protection function when not in operation.

[0030] 6. In the floor socket provided by the present invention, the leakage tripping mechanism includes an elastic top rod which can slide along the second direction. With this structural arrangement, when the leakage tripping mechanism is triggered, the driving elastic top rod drives the locking structure to move along the left end toward the second direction and give way to the operating rod, so that the matching groove and the conical part of the operating rod are separated from the lock hole of the locking structure, that is, the locking structure and the operating rod are separated from the linkage cooperation, and are driven by the contact support and the static contact is separated to realize the leakage protection function; in addition, when the leakage tripping mechanism is not triggered, the elastic top rod acts as a third elastic member to stretch toward the right end of the second direction, thereby driving the locking structure to move to the linkage position and maintain reliable contact with the matching groove of the operating rod, or driving the locking structure to reset. The design is reasonable and the cooperation is reliable.

[0031] 7. In the floor socket provided by the present invention, the power-off drive device also includes a guide structure for limiting the movement of the drive structure along the second direction. The guide structure guides the drive structure to keep the movement directions of the drive structure, the locking structure and the elastic push rod consistent, and the transmission is reliable, thereby ensuring the accuracy and reliability of the power-off drive device in driving the locking structure to move.

DETAILED DESCRIPTION

[0045] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0046] In the description of the present invention, it should be noted that the terms “first”, “second” and “third” are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements.

[0048] Example 1

[0049] The present embodiment is described in detail below with reference to the accompanying drawings:

[0050] This embodiment provides Figure 1-11 A ground socket shown in the figure comprises a base 2 having an installation cavity and a socket body 1 which is rotatably arranged on one side of the base 2 to enter and exit the installation cavity, that is, the socket body can be used only when it is rotated to open relative to the base, and is not used when it is rotated to close. A static contact 12, a first elastic member 9, a moving contact 11 away from the static contact under the action of the first elastic member 9, an operating mechanism 4 driving the moving contact 11 to overcome the force of the first elastic member and contact the static contact 12, and an interlocking mechanism 5 arranged between the operating mechanism 4 and the moving contact 11; the interlocking mechanism 5 has a locking state in which the operating mechanism 4 is linked to the moving contact, and an unlocking state in which the operating mechanism 4 is disengaged from the moving contact; and also includes:

[0051] The power-off drive device includes a drive structure 6 movably arranged on the socket body 1, the drive structure 6 is linked with the interlocking mechanism 5, and the base 2 pushes the drive structure 6 when the socket body 1 is closed to drive the interlocking mechanism 5 to move from the locked state to the unlocked state.

[0052] In the above-mentioned embodiment, an interlocking mechanism 5 is provided between the operating mechanism 4 and the moving contact 11 to achieve an interlocking cooperation effect. When the interlocking mechanism is in a locked state, the operating mechanism 4 forms a linkage relationship with the moving contact 11, thereby driving the moving contact 11 to contact with the static contact 12. When the interlocking mechanism is in an unlocked state, the moving contact 11 is disengaged from the operating mechanism 4 and disconnected from the static contact 12 under the action of the first elastic member 9. In this way, the circuit on-off operation of the ground socket can be realized. Therefore, the driving structure 6 of the power-off driving device is linked with the interlocking mechanism 5. When the ground socket is not in use, the ground socket is disconnected through the socket body. 1 is rotated and closed in the base 2, so that the driving structure 6 is pushed by the base 2 to move into the socket body 1, and then the interlocking mechanism 5 is driven to move from the locked state to the unlocked state, which can trigger the disconnection action of the moving contact 11 and the static contact 12, and realize the power-off isolation of the socket body, thereby avoiding the leakage of the ground socket buried in the ground groove, and the power-off drive device can be manually operated to realize rapid power-off protection when the ground socket is in use, so as to cope with emergency situations. The design is reasonable, the operation is convenient, and the electric shock hazard to people can be effectively avoided. It is practical, safe and reliable.

[0053] Combination Figure 4-7 As shown, the floor socket of this embodiment includes a contact support 13 slidably mounted on the socket body 1, the moving contact 11 is arranged on the contact support 13, and the static contact 12 is arranged on the middle partition 14 in the socket body 1 corresponding to the moving contact. The interlocking mechanism includes a locking structure 51 movably mounted on the contact support, and the locking structure 51 has a linkage position linked with the operating mechanism 4 and a free position disengaged from the linkage with the operating mechanism 4 when moving relative to the contact support 13. It can be seen from the above structure that the locking structure 51 plays a role of linkage connection or linkage release between the operating mechanism and the contact support. Therefore, when the operating mechanism 4 and the locking structure 51 form a linkage relationship, the linkage cooperation between the operating mechanism 4 and the contact support 13 is also promoted, so that the operating mechanism 4 drives the moving contact on the contact support 13 to contact the static contact. Conversely, after the operating mechanism 4 and the locking structure 51 are released from the linkage relationship, the contact support 13 is no longer restricted by the linkage of the operating mechanism, and the moving and static contacts can be disconnected. The design is reasonable and the transmission is reliable.

[0054] According to the above embodiment, it is further preferred that the moving contact 11 moves along the first direction close to or away from the stationary contact, combined with Figure 3-4It can be seen that the first direction is represented as a direction perpendicular to the bottom surface of the socket body, and the operating mechanism 4 includes an operating rod 41 that can move along the first direction and extend between the middle partition 14 and the contact support 13, and a second elastic member 42 is arranged between the socket body 1 and the operating rod 41. After moving downward, the operating rod needs to rely on the force of the second elastic member 42 to reset and move upward. Therefore, through the linkage between the operating mechanism 4 and the contact support 13, the second elastic member 42 drives the operating rod 41 to move along the first direction to drive the moving contact 11 to move toward the static contact 12 to realize a closed circuit.

[0055] The following combination Figure 3-7 The arrangement of the operating lever and the locking mechanism is described in detail:

[0056] In order to enable the operating rod to drive the contact support to move upward, the outer periphery of the operating rod 41 has a matching structure 52; the interlocking mechanism 5 includes the locking structure 51 and a third elastic member, the locking structure 51 is movably arranged on the contact support 13 along a second direction perpendicular to the first direction, that is, the second direction is a direction parallel to the bottom surface of the socket body, and the locking structure 51 has a locking portion along the second direction that cooperates with the matching structure 52 to link with the operating rod 41, and a free portion that allows the operating rod to move freely; the elastic force of the third elastic member drives the locking portion to cooperate with the matching structure 52 to achieve reliable contact. Furthermore, in order to achieve the matching connection between the operating rod 41 and the locking structure 51 in the contact support, the contact support 13 is formed with a first through hole suitable for connecting the locking structure and a second through hole for connecting the operating rod along the first direction and the second direction respectively. It can be seen from the above structure that the relative position of the locking portion and the free portion changes relative to the operating rod 41 when following the movement of the locking structure 51, such as Figure 7 and Fig. 9 As shown in the position, when the operating rod 41 contacts the locking portion, the operating rod position is limited by the matching structure and the locking portion, so that the operating rod and the locking structure form a linkage relationship; Figure 6 The position shown in the figure is not constrained when the operating rod contacts the free part, that is, the operating rod is disengaged from the locking structure, so that the contact support and the operating rod are separated from each other under the action of the first elastic member and the second elastic member, respectively, to realize the disconnection action of the moving and static contacts.

[0057] As a specific setting method, such as Figure 9-11As shown, the matching structure 52 is a matching groove opened on the operating rod, and the locking structure 51 has a locking hole 53 allowing the operating rod to pass through, and one side of the locking hole 53 extends into the matching groove under the action of the third elastic member. In the present embodiment, the locking hole is preferably a U-shaped hole, and one side of the locking hole is the closed end of the U-shaped hole. In summary, the locking portion of the locking structure 51 corresponds to the closed end of the locking hole 53, and the free portion corresponds to the through hole portion of the locking hole 53. Therefore, when one side of the locking hole is stuck in the matching groove, a linkage relationship between the operating rod 41 and the locking structure 51 is formed.

[0058] Combination Figure 9-10 As shown, the bottom of the operating rod 41 is provided with the matching groove and a cone 43 provided below the matching groove, and the cone 43 increases in size along the first direction from the bottom end of the operating rod 41. This structural setting is conducive to the operating rod passing through the locking hole 53 more smoothly with the help of the cone 43. During the pressing process of the operating rod 41, the locking structure 51 is moved out of position by the cone 43 pushing one side of the locking hole, until the cone 43 passes through the locking hole 53, and one side of the locking hole extends into the matching groove under the action of the third elastic member, limiting the cone below the locking hole, and realizing linkage matching.

[0059] Combine the following Figure 3 The specific arrangement of the first elastic member and the second elastic member is described in detail:

[0060] The first elastic member 9 is sleeved on the operating rod 41, one end of which abuts against the mounting groove on the other side of the middle partition 14, and the other end abuts against the spring seat 132 formed on the contact support 13. The first elastic member applies a downward force to the contact support 13. Therefore, after the operating rod and the contact support are released, the contact support 13 can drive the moving contact 11 to separate from the static contact 12 under the action of the first elastic member 9.

[0061] Further preferably, the second elastic member 42 is sleeved on the operating rod, one end of which abuts against the end cap 411 set at the top of the operating rod 41, and the other end abuts against the mounting groove on one side of the middle partition 14, and the second elastic member applies a force to the operating rod 41 to drive the contact support 13 to move upward; wherein, the elastic force of the second elastic member 42 is greater than the elastic force of the first elastic member 9, and therefore, after the operating rod and the contact support form a linkage fit, the operating rod 41 can drive the moving contact 11 on the contact support 13 to contact the static contact 12 under the action of the second elastic member 42.

[0062] The floor socket provided in this embodiment also includes a leakage tripping mechanism 3 arranged in the socket body 1, and the leakage tripping mechanism 3 has a driving end that drives the locking structure 51 to move along the second direction to the free position when triggered. The advantage of such a setting is that when leakage occurs, the locking mechanism is driven to an unlocked state by the leakage tripping mechanism 3, so that the operating rod 41 and the contact support 13 are disengaged from the linkage, thereby triggering the disconnection action of the moving contact 11 and the static contact, playing a role in leakage protection, and timely cutting off the leakage circuit to ensure the safety of the line. Therefore, the floor socket of the present invention has both leakage protection function and power-off protection function when not in operation.

[0063] Combine the following Figure 5-9 The specific setting method of the leakage tripping structure is described in detail:

[0064] The leakage tripping mechanism 3 includes an elastic push rod 31 which is slidable along the second direction, the driving end is arranged on the elastic push rod, the locking structure 51 passes through one end of the contact support and cooperates with the driving structure 6, and the other end cooperates with the elastic push rod 31, the elastic push rod 31 is the third elastic member, which provides the locking structure with a force to cooperate with the driving structure. Further preferably, a control circuit board 8 for controlling the tripping action of the leakage tripping mechanism 3 is arranged in the socket body 1, and the leakage tripping mechanism 3 is a leakage release, which includes an electromagnetic coil and a sensing iron core arranged in linkage with the elastic push rod. When the control circuit board 8 detects a leakage current signal, it will issue a control command to drive the elastic push rod 31 of the leakage release The retraction action, that is, the elastic push rod 31 moves toward the left end of the second direction, thereby driving the locking structure 51 to move along the second direction and give way to the operating rod, so that the matching groove and the cone part of the operating rod 41 are separated from the lock hole of the locking structure 51, that is, the locking structure 51 and the operating rod 41 are disengaged from the linkage, and driven by the contact support, the static contact is separated to realize the leakage protection function; in addition, when the leakage tripping mechanism 3 is not triggered, the elastic push rod 31 acts as a third elastic member to stretch toward the right end of the second direction, thereby driving the locking structure 51 to move to the linkage position and maintain reliable contact with the matching groove of the operating rod 41, or driving the locking structure 51 to be reset in time after being pushed and moved by the driving structure 6. The design is reasonable and the cooperation is reliable.

[0065] like Fig. 9As shown, an annular groove 32 is provided on the driving end, and a socket 54 is formed at the corresponding end of the locking structure 51 and inserted into the annular groove 32. The extension direction of the socket 54 is parallel to the first direction. This structural setting enables the locking structure 51 to follow the contact support to move synchronously along the first direction through the cooperation of the socket 54 and the annular groove 32, and will not separate from the elastic push rod, and can also ensure the linkage cooperation between the locking structure 51 and the elastic push rod 31 in the second direction. The structure is simple and the design is ingenious.

[0066] In this embodiment, the power-off drive device also includes a guide structure for limiting the movement of the drive structure 6 along the second direction, and the guide structure includes a guide protrusion 7 fixedly arranged relative to the socket body 1, and a guide groove 61 formed on the drive structure 6 and slidably matched with the guide protrusion. A limit plate 71 is provided on the top of the guide protrusion 7 to prevent the drive structure 6 from escaping from the guide protrusion 7. The guide structure guides the drive structure 6 to keep the movement directions of the drive structure, the locking structure and the elastic push rod consistent, and the transmission is reliable, thereby ensuring the accuracy and reliability of the power-off drive device in driving the locking structure 51 to move.

[0067] Further preferably, the driving structure 6 is a push rod, which includes an operating end 62 extending from the socket body 1, and the operating end 62 has an arc surface that cooperates with the inner wall of the base 2 to achieve a sliding fit, reduce friction resistance, and improve trigger sensitivity and operating comfort.

[0068] Combine the following Figure 3 , Figure 6-7 The working principle of the ground socket in this example is explained as follows:

[0069] When the ground socket is in normal use, the socket body 1 is rotated to open, and the operating rod 41 is pressed to form a linkage with the locking structure 51. Under the action of the second elastic member 42, the operating rod 41 drives the contact support 13 to move upward along the first direction, so that the moving contact 11 and the static contact 12 are in contact, and the circuit is turned on.

[0070] When the floor socket is not in use, the socket body 1 is rotated to close, and the driving structure 6 is pushed by the base 2 to move in the socket body 1 along the second direction, thereby driving the locking structure 51 to release the linkage with the operating rod 41, so that the operating rod 41 and the contact support 13 are separated from each other. At this time, the operating rod 41 is reset and moved upward away from the contact support under the action of the second elastic member 42, and the contact support 13 drives the moving contact 11 and the static contact 12 to separate under the action of the first elastic member 9, thereby realizing power-off protection; when leakage occurs, the locking structure 51 is driven to release the linkage with the operating rod 41 through the leakage tripping mechanism 3, so that the contact support 13 can drive the moving contact 11 and the static contact 12 to separate under the action of the first elastic member, thereby realizing leakage protection.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods.
