Description

Technical Field

[0001] The utility model belongs to the technical field of sockets, and particularly relates to a panel-linked secondary power-connecting socket. Background Art

[0002] The existing socket structure is mainly composed of key components such as a front panel, a fixing bracket, a safety door, socket sleeves, and a base. It is a fixed connector used to connect the plug of an electrical appliance to an external power supply circuit. The safety door structure is composed of a PC flame-retardant material part and a spring. Its original design intention is to prevent children from accidentally touching the socket, effectively avoiding the occurrence of electric shock accidents and providing an important guarantee for household safety. The socket sleeves are the core components connected to the plug, made of tin phosphor bronze material with excellent electrical conductivity, thermal conductivity, and mechanical elasticity to ensure the stability and safety of current transmission. The base further plays a role in insulation and fixing the socket sleeves, the safety door, and the wiring terminals to ensure the stability and safety of the entire socket structure.

[0003] In the existing socket structure, arc situations often occur. The reasons can be attributed to multiple aspects. Firstly, poor contact is one of the main reasons for generating arcs. After the socket becomes old and loose, the contact resistance between the plug and the socket increases, and arcs are easily generated during the plugging and unplugging process. Secondly, overloading of the circuit is also an important factor for arc generation. Long-term overloading not only causes arc phenomena but also accelerates the aging of electrical equipment. In addition, hesitant plugging and unplugging actions or poor socket quality may also cause arcs. The essence of an arc is that when two conductors are in a virtual connection state, the voltage directly breaks down the air to generate current. Since the air resistance is relatively large, the current has the characteristics of high temperature and luminescence when flowing in the air.

[0004] The high-temperature characteristic of the arc poses a severe test to the flame retardancy of the plug and the socket. If the arc is too large, it may also pop out and injure people or ignite other items, causing a fire. Secondly, the arc has a certain corrosive effect on metals. Long-term arcing will affect the flatness of the internal spring clips of the socket, thereby affecting conductivity and possibly exacerbating the next arcing phenomenon. In addition, the arc may also pose a potential threat to the surrounding environment and personnel safety, such as arc-induced flashover short circuits and injury accidents. Now the requirements for electrical safety are becoming more and more stringent. In the existing technology, in order to avoid arc situations, a separate arc extinguishing structure is adopted, but this setting method increases the cost of the socket. There is currently a lack of a low-cost safety socket technology. Content of the Utility Model

[0005] In order to solve the problems existing in the prior art, the utility model provides a panel-linked secondary power-connecting socket, the purpose of which is to transfer the position where arcs often occur, thereby eliminating the factors of plugging and unplugging the plug, and improving the electrical safety of the socket in a low-cost manner.

[0006] The technical solution adopted by the utility model is as follows:

[0007] In a first aspect, the present utility model provides a panel-linked secondary power connection socket, which connects an external circuit and a plug and realizes secondary power connection internally. It includes a housing structure of the socket. A plurality of jacks corresponding to the plug are provided on the end face of the housing. Inside the jacks, there are socket sleeves for connecting the plug as an independent structure and inner conductors for connecting the external circuit. A trigger is provided on the end face of the housing where the jacks are provided. The trigger is linked with the socket sleeve and / or the inner conductor. When the plug contacts and activates the trigger, the inner conductor is electrically connected to the socket sleeve connected to the plug.

[0008] It should be noted that both the socket sleeve and the inner conductor are common structures in sockets. The socket sleeve is used to connect the pins of the plug. The socket sleeve usually has a groove for the pin to insert and achieve clamping. In the present utility model, the inner conductor and the socket sleeve are kept separated before the plug is inserted. The inner conductor is used to connect the external circuit, and the socket sleeve is used to connect the plug. In a conventional socket, the inner conductor is directly electrically connected to the socket sleeve. In the present utility model, they are in a separated state. In the initial state, the socket sleeve is not powered. When the plug is inserted and contacts the socket sleeve, the trigger moves.

[0009] The trigger being linked with the socket sleeve and / or the inner conductor means that when the trigger moves, it is linked with either one or both of the inner conductor and the socket sleeve, so that when the trigger moves, it pushes the two components into contact to achieve secondary power connection. Since the inner conductor remains connected to the external circuit, and the socket sleeve has been connected to the plug before the two components are connected, when the two components are connected, even if an electric arc is generated, it will form between the two components, which is different from that between the plug and the socket sleeve of the existing socket. The so-called "and / or" includes the limitation of either one or both being linked simultaneously.

[0010] Combined with the first aspect, the present utility model provides a first implementation manner of the first aspect. The trigger has a trigger end corresponding to the plug, and the trigger end is within the area surrounded by the connecting lines of the edges of a plurality of jacks corresponding to the same plug.

[0011] It should be noted that the so-called "corresponding to the same plug" means that there are a plurality of jacks on the same end face. Common two-pin, three-pin, and USB sockets all correspond to separate plugs, and the effects of the secondary power connection to be achieved are relatively independent. Therefore, setting the trigger end of the trigger within the largest range surrounded by the jacks can ensure that when the normal plugging and use of the conventional plug are not changed and affected, it can be covered by the plug as much as possible to achieve the triggering effect. The so-called "connecting lines of the jack edges" refers to the area surrounded by the connecting straight lines of the outermost positions of the jacks and the outermost positions of adjacent jacks. Most of the edges of this area are straight lines, that is, it can correspond to the smallest area covered by the plug on the panel.

[0012] In combination with the first aspect, the present utility model provides a second implementation manner of the first aspect. The triggering member is a mechanical component, which is movably arranged on the housing and is elastically limited with the housing through an elastic member.

[0013] The triggering member has a triggering end outside the housing, and the plug pushes the triggering end to cause the internal socket and / or the inner conductor to be electrically connected.

[0014] It should be noted that the so-called mechanical component refers to a component whose triggering method is mechanical movement, that is, a triggering signal generated by the movement of the triggering member itself.

[0015] In combination with the first aspect, the present utility model provides a third implementation manner of the first aspect. The triggering member is two magnetic components arranged inside and outside the housing. The plug contacts the external magnetic component to push the internal magnetic component to move, causing the internal socket and / or the inner conductor to be electrically connected.

[0016] In combination with the first aspect, the present utility model provides a fourth implementation manner of the first aspect. The triggering member is a sensor arranged on the housing. An independently powered detection circuit is provided inside the housing. The sensor is arranged on the detection circuit, and a relay for controlling the electrical connection between the inner conductor and the socket is also provided on the detection circuit.

[0017] In combination with the first aspect or several implementation manners of the first aspect, the present utility model provides a fifth implementation manner of the first aspect. The housing includes a front panel and a bottom case that are snap-fitted and connected. The front panel is provided with jacks corresponding to two-pin and / or three-pin plugs, and the bottom case has a wiring terminal for connecting to an external circuit.

[0018] In combination with the fifth implementation manner of the first aspect, the present utility model provides a sixth implementation manner of the first aspect. The triggering member is arranged at the center of the jack of the two-pin or three-pin plug.

[0019] In combination with the second or third implementation manner of the first aspect, the present utility model provides a seventh implementation manner of the first aspect. The triggering member has a movable head inside the housing. A moving contact and a wiring part are arranged on the movable head. A static contact corresponding to the moving contact is arranged on the inner conductor. The socket or the inner conductor is electrically connected to the wiring part of the movable head through a conductor.

[0020] The beneficial effects of the present utility model are as follows:

[0021] By providing a triggering member corresponding to the plug on the panel of the socket, the present utility model is different from other ways of triggering secondary power connection, has better adaptability to the plug, lower cost, and has a better protection effect.

[0035] Embodiment 1:

[0036] This embodiment discloses a secondary power connection socket with panel linkage. Based on the existing socket structure, that is, the connector connecting the plug of an external electrical appliance to the power supply line, but not limited to the plug structure of the electrical appliance, it can generally refer to all devices powered by a plug.

[0037] The so-called secondary power connection means that when the plug contacts the conductive body in the socket, electrical contact will occur, which is the primary power connection. This is common in the socket structures of the prior art. Since the socket itself does not limit the plug structure and they are all of general specifications, the primary power connection between the plug and the socket may cause unsafe factors due to the common generation of electric arcs. The socket in this embodiment has the function of secondary power connection, that is, when the plug itself contacts the conductive body in the socket, it is not powered on. Through the isolation structure provided inside the socket, the secondary power connection function inside the socket can be realized in the way that the plug contacts the conductive body first and then is powered on, which can transfer the position where the electric arc is generated, so as to have a safer setting method for arc extinguishing or restricting the electric arc, and improve the safety performance.

[0038] This embodiment is based on the existing socket structure of wall sockets and is optimized and defined on this basis.

[0039] Specifically, it includes a housing with a conductive component inside, namely the socket sleeve 6 and the inner conductor 8 in a separated state. There are jacks 2 on the surface of the housing, and in this embodiment, the specifications of the jacks 2 are the conventional two-pin or three-pin types. A separate socket sleeve 6 structure is provided corresponding to each jack 2. If there are both two-pin and three-pin sockets at the same time, several socket sleeves 6 corresponding to the live wire and the neutral wire jointly correspond to one inner conductor 8.

[0040] There is a wiring hole 5 on the other end face of the housing. The wiring hole 5 is used to connect to the external circuit, that is, the common live wire, neutral wire, and ground wire. The external circuit is connected to the inside of the housing through the wiring hole 5 and is connected to the corresponding inner conductor 8.

[0041] There are several trigger members 3 on the end face of the housing where the jacks 2 are provided. The trigger member 3 corresponds to the plug. There is a linkage relationship between the inside of the trigger member 3 and the inner conductor 8 and the socket sleeve 6. When the plug is inserted into the corresponding jack 2, the socket sleeve 6 contacts the pin of the plug, and then the trigger member 3 is triggered, causing the socket sleeve 6 and / or the inner conductor 8 to move to achieve the conductive connection relationship between the two. Among them, the plug first contacts the socket sleeve 6, and then the inner conductor 8 is conductively connected to the socket sleeve 6.

[0042] It should be noted that the sequence between the socket sleeve 6 and the plug, and between the inner conductor 8 and the socket sleeve 6 has been determined. Therefore, there are several ways, that is, before the trigger member 3 is triggered, the plug has already contacted the socket sleeve 6, and then the trigger member 3 is triggered to achieve the sequence. In another way, the trigger member 3 is triggered first, but there is a time delay in the linkage of the trigger member 3 to make the inner conductor 8 and the socket sleeve 6 contact. After the plug contacts the socket sleeve 6, the inner conductor 8 and the socket sleeve 6 contact again, so as to achieve the limitation of the sequence.

[0043] Regarding the triggering relationship of the trigger member 3, in one embodiment, the trigger member 3 is linked with the inner conductor 8, and the inner conductor 8 can move inside the housing or the inner conductor 8 has a partially movable part. When the plug is inserted into the corresponding jack 2, the trigger member 3 is triggered, driving a partial displacement of the movable part of the inner conductor 8, so as to contact the fixed-position socket sleeve 6 to achieve power connection.

[0044] In another embodiment, the trigger member 3 is linked with the socket sleeve 6, and driving the socket sleeve 6 to be connected to the inner conductor 8 can also achieve the effect of triggering secondary power connection. However, in this triggering method, since the socket sleeve 6 itself will contact the plug, this embodiment is only a theoretically feasible solution.

[0045] For the solution where the trigger member 3 triggers the relative movement of both at the same time, since the cost is higher than the previous two and the structure is more complex, it is also only a theoretically feasible solution.

[0046] In another embodiment, another independent connection structure is provided inside the socket. It can be connected to either the inner conductor 8 or the socket sleeve 6 through a flexible or extensible conductor, and then the connection structure is driven by the trigger member 3 to approach the other unconnected component to achieve trigger power connection.

[0047] Furthermore, the trigger member 3 in this embodiment includes several implementation manners as follows. In the following implementation manners, it is based on a socket structure of a wall socket. The housing of this structure is a split structure formed by the front panel 1 and the bottom shell 4 being snapped together, and is installed in the socket box on the wall through bolts. The front panel 1 has a five-hole socket, that is, a specification with one two-pin and one three-pin. The bottom shell 4 is provided with several wiring holes 5, and corresponding wiring terminals are arranged inside for connecting to the external circuits of the neutral wire, live wire, and ground wire.

[0048] As an implementation manner, referring to Figures 1-5 , the trigger member 3 is a mechanical structure, specifically a plug-in structure arranged in the central empty area between the two-pin and three-pin. An opening is provided at the corresponding position on the front panel 1 for the trigger member 3 to be slidably connected. Inside the front panel 1, there is a limiting post 9, that is, a tubular structure formed by the inner edge of the opening extending inwards, and the trigger member 3 is a rod, which is restricted by the limiting post 9 to slide linearly.

[0049] A spring is arranged inside the limiting post 9 to give the trigger member 3 an outward elastic force all the time.

[0050] The trigger member 3 passes through the limiting post 9 and has a certain length left on the front panel 1 for contacting and triggering the end face of the plug. And a movable head 7 is connected to the part of the trigger member 3 that passes through the limiting post 9. The two ends of the movable head 7 have circular-hole-shaped connection parts, and a movable contact 10 protrudes from the lower part. Referring to Figure 4 and Figure 5 , the inner conductor 8 is a metal extension sheet body, and a static contact is provided corresponding to the movable contact 10. When the trigger member 3 is pushed inwards by the plug, the movable contact 10 contacts the static contact to achieve secondary power connection, and the circular-hole-shaped connection part can be connected to the socket sleeve 6 or the inner conductor 8 through a flexible wire.

[0051] As an implementation manner, the trigger member 3 is a multi-sensor structure of sound wave, light, and piezoelectric type arranged on the front panel 1. And a circuit board is arranged inside the front panel 1, which can be powered by an external circuit to achieve real-time monitoring. The inner conductor 8 and the socket sleeve 6 are respectively connected to this circuit board, and the connection / disconnection is achieved through a relay arranged on the circuit board.

[0052] After the plug is inserted, the sensor sets a suitable sensing distance. After the plug contacts the socket sleeve 6 for a certain time and then enters the detection range of the sensor, the relay on the circuit board is triggered at this time, so that the inner conductor 8 and the socket sleeve 6 are electrically conductive.

[0053] The utility model is not limited to the above optional embodiments, and any person can obtain other various forms of products under the inspiration of the utility model. The above specific embodiments should not be construed as limiting the protection scope of the utility model, and the protection scope of the utility model should be defined by the claims, and the description can be used to interpret the claims.
