Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electrical equipment, and in particular to a wiring terminal and a socket. Background Art
[0002] A socket is a device used to connect electrical equipment to a power source. It has two interconnected terminals, which can be used to connect to the power source and electrical equipment respectively.
[0003] The socket is also provided with a plurality of wiring terminals, which can be used to connect a power source or an electrical device. However, in the related art, after the socket connects the electrical device to the power source, the power source and the electrical device remain energized, which poses a safety hazard during the use of electricity. Utility Model Content
[0004] The present application provides a wiring terminal and a socket, which can reduce safety hazards during the use of the socket.
[0005] In a first aspect, the present application provides a terminal block comprising a base, a contact assembly, and a reset lever. The base comprises an interior mounting cavity, a cavity wall of which is provided with a reset hole extending through the base. The contact assembly is disposed within the mounting cavity, has an on state and an off state, and is used to connect to an electrical device. The reset lever extends through the reset hole and is movable relative to the reset hole to switch between a first position and a second position. The reset lever is also connected to the contact assembly.
[0006] When the terminal is overloaded, the contact assembly switches from the on state to the off state, and the contact assembly drives the reset lever to move from the first position to the second position. When the contact assembly is in the off state and the reset lever is driven to move from the second position to the first position, the reset lever drives the contact assembly to switch to the on state.
[0007] In the embodiment of the present application, in addition to the normal function of connecting other devices to the terminal, the terminal also has an overload function. When the terminal is overloaded, the contact assembly can be switched to the disconnect state, so that the terminal can be disconnected, reducing the safety risks when using the terminal.
[0008] Optionally, the base includes an upper cover and a base arranged along the first direction, the upper cover and the base being buckled together to form a mounting cavity. A reset hole is provided on the upper cover, and the number of the reset holes is multiple, and the multiple reset holes are symmetrically arranged on the upper cover.
[0009] Through the above arrangement, the base can be formed by combining the upper cover and the base, which makes it easier to arrange the contact assembly in the installation cavity and simplifies the connection between the contact assembly and the reset rod.
[0010] Optionally, the wiring terminal further includes an indication component, which is mounted on the base and electrically connected to the contact assembly, and the indication component can indicate the status of the contact assembly.
[0011] Through the above configuration, the user can intuitively learn the status of the connection terminal.
[0012] Optionally, the indicating assembly includes a light-emitting element, a first connecting piece, and a conductive assembly. A mounting hole penetrating the base is provided on the cavity wall of the mounting cavity. The light-emitting element is mounted on the base and is opposite to the mounting hole. The light-emitting element has a first connecting end and a second connecting end. The first connecting piece is provided in the mounting cavity and is spaced apart from the contact assembly. The conductive assembly includes a first conductive member and a second conductive member spaced apart. The two ends of the first conductive member are electrically connected to the contact assembly and the first connecting end, respectively. The two ends of the second conductive member are electrically connected to the contact assembly and the second connecting end, respectively.
[0013] When the contact assembly is in the on state, the connection terminal is energized so that the light-emitting element can receive the electrical signal and emit light. When the contact assembly is in the off state, the connection terminal is de-energized and the light-emitting element is extinguished.
[0014] In this way, when the contact assembly is in the on state, the light-emitting assembly can also receive the electrical signal and emit light, notifying the user that the wiring assembly is currently in a working state. When the contact assembly is in the off state, the circuit where the light-emitting assembly is located is disconnected, causing the light-emitting assembly to go out, notifying the user that the wiring assembly is currently in an overloaded state and has stopped working.
[0015] Optionally, the indicator assembly further includes a mounting member mounted on the base and located on a side of the light-emitting element facing away from the first conductive member. The mounting member is provided with a receiving groove, and the portion of the mounting member provided with the receiving groove is light-transmissive. The light-emitting element is disposed in the receiving groove. When the light-emitting element is emitting light, the light from the light-emitting element can pass through the mounting member.
[0016] With the above arrangement, the light emitting element can be arranged on the mounting member and located inside the mounting cavity. In this way, the light emitting element can be protected by the mounting member to prevent the light emitting element from being exposed and easily damaged.
[0017] Optionally, the mounting cavity has a cavity bottom, and the base is provided with a mounting through-hole and a mounting slot, wherein the mounting through-hole opposes the cavity bottom and the mounting slot communicates with the mounting through-hole. At least a portion of the mounting member is inserted through the mounting through-hole and embedded in the mounting cavity, and is engaged with a cavity wall of the mounting cavity. A retaining rib is further provided on a side of the mounting member facing the mounting slot, and the retaining rib is interference-fitted with the cavity wall of the mounting slot.
[0018] In this way, the mounting piece can be snap-fitted to the cavity wall of the mounting cavity, thereby achieving the connection between the mounting piece and the base.
[0019] Furthermore, the clamping rib is interference-fitted with the groove wall of the installation groove, and thus the position of the installation part can be further limited, so that the possibility of movement of the installation part is reduced after the installation part is assembled.
[0020] Optionally, the first conductive member is any one of a wire and a conductive elastic member, and / or the second conductive member is any one of a conductive member and a conductive elastic member.
[0021] When at least one of the first conductive member and the second conductive member is an elastic member, the elastic member is in a pre-stressed state. A limit member is provided on the base, the limit member is located on a side of the light emitting element away from the first conductive member and abuts against the light emitting element.
[0022] In this way, electrical conduction can be achieved through the conductive elastic member or the conductive wire.
[0023] When at least one of the first conductive member and the second conductive member is an elastic member, the elastic member tends to stretch, thereby pushing the light-emitting element to move. The position-limiting member can limit the position of the light-emitting element and apply a force toward the elastic member, thereby reducing the possibility of the light-emitting element being dislodged from the mounting cavity.
[0024] Optionally, a first terminal and a second terminal are provided in the mounting cavity, the first terminal being electrically connected to the first connecting piece, and the second terminal being electrically connected to the contact assembly. A wiring through-hole communicating with the mounting cavity is provided on the base, the first terminal and the second terminal being opposite to the wiring through-hole, and the first terminal and the second terminal being used to electrically connect to the electrical device.
[0025] With the above arrangement, when connecting an electrical device, the connection can be made through the first terminal and the second terminal, thereby improving the speed of connection between the wiring terminal and the electrical device.
[0026] Optionally, the contact assembly includes a stationary contact and a dual-metal moving contact, both of which are positioned within the mounting cavity, with the stationary contact facing the dual-metal moving contact. When the contact assembly is in the on state, the dual-metal moving contact contacts the stationary contact. If the terminal is overloaded, the dual-metal moving contact deforms, separating from the stationary contact, placing the contact assembly in the off state. Simultaneously, the dual-metal moving contact drives the reset lever to its second position.
[0027] In this way, the connection terminal can be in different states by controlling the relative position relationship between the static contact piece and the dual metal dynamic contact piece.
[0028] In a second aspect, the present application provides a socket comprising any one of the connection terminals described in the first aspect.
[0029] The beneficial effects of the socket provided in the second aspect and the various possible designs of the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, and will not be repeated here.

[0050] For example, the present application embodiment provides a socket, the socket comprising: Figure 1 The connecting terminal 100 is shown.
[0051] A socket is a device used to connect an electrical appliance to a power source. In a socket equipped with the aforementioned terminal block 100, the terminal block 100 can function normally to provide a connection. Alternatively, if the terminal block 100 is overloaded, it can disconnect the electrical connection between the appliance and the power source, ensuring electrical safety and reducing potential electrical hazards.
[0052] The socket may be a wireless socket.
[0053] The connection terminal 100 provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0054] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides a terminal block 100, comprising a base 10, a contact assembly 20, and a reset rod 30. The base 10 is provided with an installation cavity 11, and a reset hole 12 is provided on the cavity wall of the installation cavity 11. The reset hole 12 passes through the base 10. The contact assembly 20 is provided in the installation cavity 11. The contact assembly 20 has an on state and an off state, and is used to connect to an electrical device. The reset rod 30 is provided in the reset hole 12 and can move relative to the reset hole 12 to switch between a first position and a second position. The reset rod 30 is also connected to the contact assembly 20.
[0055] When the terminal block 100 is overloaded, the contact assembly 20 can switch from the on state to the off state, and the contact assembly 20 can drive the reset lever 30 to move from the first position to the second position. When the contact assembly 20 is in the off state and the reset lever 30 is driven to move from the second position to the first position, the reset lever 30 can drive the contact assembly 20 to switch to the on state.
[0056] In the embodiment of the present application, the connection terminal 100 is provided with a contact assembly 20, which has an on state and an off state. Since the contact assembly 20 can be connected to an electrical device, the state of the contact assembly 20 affects the electrical energy received by the electrical device.
[0057] Therefore, when the contact assembly 20 is used in a socket and connected to a power source and an electrical device, the connection state between the power source and the electrical device can be different according to the different states of the contact assembly 20 .
[0058] Specifically, when the contact assembly 20 is in the on state, a path between the power supply and the electrical device can be formed through the contact assembly 20, allowing the electrical device to receive power and operate normally. When the contact assembly 20 is in the off state, the path between the power supply and the electrical device can be disconnected, at which point the electrical device loses power supply and stops operating.
[0059] The terminal block 100 further includes a reset lever 30, which is inserted into the reset hole 12 on the base 10. Since the reset lever 30 is connected to the contact assembly 20, the movement of one of the reset lever 30 and the contact assembly 20 will affect the movement of the other.
[0060] Specifically, when the connection terminal 100 works normally, the reset lever 30 may be in the first position.
[0061] When the terminal block 100 is overloaded after a period of operation, the contact assembly 20 can be actuated to switch the contact assembly 20 from the on state to the off state. During the switching process of the contact assembly 20, the contact assembly 20 can drive the reset rod 30 to move from the first position to the second position.
[0062] When it is necessary to reset the terminal block 100 to reconnect the electrical component and the power supply, the reset lever 30 can be moved from the second position to the first position, so that the reset lever 30 can drive the contact assembly 20 to move, so that the contact assembly 20 can be switched from the disconnected state to the connected state.
[0063] As can be seen, in the embodiment of the present application, in addition to the normal function of connecting the terminal 100 to other external devices (such as electrical equipment and power supplies), it also has an overload function. When the terminal 100 is overloaded, the contact assembly 20 can be switched to the disconnected state, so that the terminal 100 can be disconnected, reducing the safety risks when using the terminal 100.
[0064] In this way, when the wiring assembly is applied to the socket, the potential safety hazards of the socket during power use can also be reduced.
[0065] It should be noted that, in order to make it easier for the user to operate the reset rod 30, when the reset rod 30 is in the second position, the reset rod 30 can partially extend from the reset hole 12, so that the user can apply force through the extended part of the reset rod 30.
[0066] In addition, if Figure 1 and Figure 4 As shown, a reset groove 19 may be formed inside the base 10 , and the reset rod 30 may be embedded in the reset groove 19 . In this way, the reset groove 19 may limit the movement of the reset rod 30 and reduce the possibility of the reset rod 30 being offset.
[0067] In some embodiments, as Figure 1 and Figure 2 As shown, the base 10 may include an upper cover 13 and a base 14 arranged along a first direction X. The upper cover 13 and the base 14 are engaged to form a mounting cavity 11. A plurality of reset holes 12 are provided on the upper cover 13, and the plurality of reset holes 12 are symmetrically arranged on the upper cover 13.
[0068] Through the above arrangement, the base 10 can be formed by combining the upper cover 13 and the base 14 , which facilitates the placement of the contact assembly 20 in the mounting cavity 11 and simplifies the connection between the contact assembly 20 and the reset rod 30 .
[0069] Since there are multiple reset holes 12 on the upper cover 13, and the multiple reset holes 12 are symmetrically arranged, when assembling the upper cover 13 onto the base 14, the upper cover 13 can be assembled in different ways, reducing the tedious steps of distinguishing the assembly angle of the upper cover 13 during the assembly process, and facilitating assembly.
[0070] It should be noted that the upper cover 13 can also be formed by a cover body and a main body, wherein an assembly hole is provided on the main body, and the upper cover 13 is provided at the assembly hole. The reset hole 12 can be provided on the cover body.
[0071] At this time, when assembling the terminal block 100 , the contact assembly 20 and the reset lever 30 may be placed on the base 14 first, and after the installation is completed, the main body and the cover may be assembled in sequence.
[0072] The number of the reset holes 12 can be set according to the structure of the cover. Figure 1 As shown, the cover body may be a rectangular structure. In this case, two reset holes 12 may be symmetrically provided along the center of the cover body.
[0073] Alternatively, the cover body may also be a square structure. In this case, four reset holes 12 may be provided, and each reset hole 12 is provided corresponding to one side of the cover body.
[0074] The specific configuration of the cover and the reset hole 12 is not specifically limited in this embodiment of the present application.
[0075] It should also be noted that the base 14 and the upper cover 13 can be fastened together in a snap-fit manner. Figure 1 The base 14 may be provided with a snap-fitting boss 141 , the upper cover 13 may be provided with a snap-fitting hole 131 , and the snap-fitting boss 141 may be embedded in the snap-fitting hole 131 .
[0076] In addition, if Figure 1 As shown, a positioning column 132 may also be provided on the upper cover 13 to position the connection terminal 100 when the connection terminal 100 is placed on the socket.
[0077] In some embodiments, as Figures 1 to 3 As shown, the contact assembly 20 may include a stationary contact 21 and a dual-metal movable contact 22. Both the stationary contact 21 and the dual-metal movable contact 22 are disposed within the mounting cavity 11, with the stationary contact 21 facing the dual-metal movable contact 22. When the contact assembly 20 is in the on state, the dual-metal movable contact 22 contacts the stationary contact 21. When the terminal block 100 is overloaded, the dual-metal movable contact 22 deforms and separates from the stationary contact 21, placing the contact assembly 20 in the off state. Simultaneously, the dual-metal movable contact 22 drives the reset lever 30 to move to the second position.
[0078] In this way, the connection terminal 100 can be in different states by controlling the relative position relationship between the static contact piece 21 and the dual-metal dynamic contact piece 22 .
[0079] The bimetallic moving contact 22 can be made of layers of metal materials with different thermal expansion coefficients. When the temperature is high, the different layers of material deform to different degrees, causing the bimetallic moving contact 22 to bend as a whole. This allows the bimetallic moving contact 22 to bend and separate from the stationary contact 21 when the terminal block 100 is overloaded.
[0080] It should be noted that a static contact point may be provided on the static contact piece 21 and a dynamic contact point may be provided on the bimetallic dynamic contact piece 22. The static contact point is opposite to the dynamic contact point, and the static contact point and the dynamic contact point may cooperate to connect or disconnect the contact assembly.
[0081] At this time, the end of the bimetallic moving contact piece 22 that is not provided with the moving contact point can be connected to the reset rod 30 .
[0082] It should also be noted that the connection terminal 100 connects the live wire and the neutral wire, wherein the live wire to ground voltage is 220 V. In order to disconnect the live wire when the contact assembly 20 is in the off state to prevent electric shock, the contact assembly 20 can be electrically connected to the live wire.
[0083] During actual connection, both ends of the contact assembly 20 must be connected to the live wire, and the dual-metal moving contact 22 and the static contact 21 can be connected to the live wire respectively.
[0084] Of course, the contact assembly 20 may not be directly connected to the live wire, and an additional connecting piece may be provided, through which the contact assembly 20 and the live wire can be connected.
[0085] Here, the process when the connection terminal 100 is overloaded is described in detail.
[0086] Combine Figure 5 , Figure 5 The figure shows that when the terminal block 100 is overloaded, the double-metal movable contact piece 22 is deformed and separated from the static contact piece 21. At this time, the right end of the double-metal movable contact piece 22 drives the reset rod 30 to move upward.
[0087] When the user presses the reset lever 30 downward, the reset lever 30 can exert a downward force on the right end of the double-metal dynamic contact piece 22, causing the left end of the double-metal dynamic contact piece 22 to move toward the direction close to the static contact piece 21, thereby making the static contact piece 21 contact the double-metal dynamic contact piece 22. Figure 6 shown.
[0088] In the present application, due to the arrangement of the contact assembly 20 in the terminal block 100 , the terminal block 100 has different states, namely, a working state when the contact assembly 20 is in the connected state, and an overload state when the contact assembly 20 is in the disconnected state.
[0089] In order to allow the user to intuitively know the status of the terminal block 100, the present application further provides an indication component 40 in the terminal block 100, such as Figure 1 shown.
[0090] The indicating assembly 40 is installed on the base 10 and is electrically connected to the contact assembly 20 . The indicating assembly 40 can indicate the status of the contact assembly 20 .
[0091] In the embodiment of the present application, the indicating component 40 has different configurations, and the following two are used as examples for illustration.
[0092] Method 1: Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, the indicating assembly 40 includes a light-emitting element 41, a first connecting piece 401, and a conductive assembly 42. A mounting hole penetrating the base 10 is provided on the cavity wall of the mounting cavity 11. The light-emitting element 41 is mounted on the base 10 and is opposite to the mounting hole. The light-emitting element 41 has a first connecting end and a second connecting end. The first connecting piece 401 is disposed in the mounting cavity 11 and is spaced apart from the contact assembly 20. The conductive assembly 42 includes a first conductive member 421 and a second conductive member 422 spaced apart. The two ends of the first conductive member 421 are electrically connected to the contact assembly 20 and the first connecting end, respectively. The two ends of the second conductive member 422 are electrically connected to the contact assembly 20 and the second connecting end, respectively.
[0093] When the contact assembly 20 is in the on state, the connection terminal 100 is energized so that the light emitting element 41 can receive the electrical signal and emit light. When the contact assembly 20 is in the off state, the connection terminal 100 is de-energized and the light emitting element 41 is extinguished.
[0094] According to the previous description, the contact assembly 20 is connected to the live wire. In order to enable the light-emitting element 41 to be connected to different two-phase lines, the first connecting piece 401 can be an N-pole connecting piece for connecting to the neutral wire.
[0095] Since the two ends of the first conductive member 421 are electrically connected to the contact assembly 20 and the first connection end respectively, and the two ends of the second conductive member 422 are electrically connected to the contact assembly 20 and the second connection end respectively, the light-emitting element 41 can be electrically connected to the live wire and the neutral wire through the first conductive member 421 and the second conductive member 422.
[0096] In this way, when the contact assembly 20 is in the on state, the light emitting element 41 can also receive the electrical signal and emit light, prompting the user that the wiring assembly is currently in the working state.
[0097] When the contact assembly 20 is in the disconnected state, the circuit where the light emitting element 41 is located is disconnected, so that the light emitting element 41 is extinguished, prompting the user that the wiring assembly is currently in an overloaded state and has stopped working.
[0098] Since a mounting hole penetrating the base 10 is provided on the cavity wall of the mounting cavity 11, and the light-emitting element 41 is opposite to the mounting hole, when the light-emitting element 41 is illuminated, the light emitted by the light-emitting element 41 can be emitted through the mounting hole, so that the user can observe whether the light-emitting element 41 is illuminated without opening the upper cover 13, making it easier for the user to judge the status of the wiring assembly.
[0099] It should be noted that the light-emitting element 41 may be a lamp board, a circuit board provided with lamp beads, etc. The specific type of the light-emitting element 41 is not specifically limited in the embodiment of the present application.
[0100] In some embodiments, as Figures 1 to 4 ,as well as Figure 7 As shown, the indicator assembly 40 may further include a mounting member 43, which is mounted on the base 10 and located on a side of the light-emitting element 41 facing away from the first conductive member 421. The mounting member 43 is provided with a receiving groove 431. The portion of the mounting member 43 provided with the receiving groove 431 is light-transmissive, and the light-emitting element 41 is disposed in the receiving groove 431. When the light-emitting element 41 is emitting light, the light from the light-emitting element 41 can pass through the mounting member 43.
[0101] Through the above arrangement, the light emitting element 41 can be arranged on the mounting member 43 and located inside the mounting cavity 11. In this way, the light emitting element 41 can be protected by the mounting member 43 to prevent the light emitting element 41 from being exposed and easily damaged.
[0102] Since the portion of the mounting member 43 provided with the receiving groove 431 is light-transmissive, when the light-emitting element 41 emits light, the light of the light-emitting element 41 can be emitted through the mounting member 43 for observation by the user.
[0103] Based on this, the difficulty of the user in judging the status of the connection terminal 100 due to the arrangement of the mounting member 43 can be reduced.
[0104] It should be noted that the mounting member 43 may be only partially light-transmissive. Figure 8 As shown, a light-transmitting light guide column can be set on the mounting member 43, and the light guide column is opposite to the position of the accommodating groove 431 and the luminous position on the light-emitting element 41. At this time, other positions of the mounting member 43 may not be light-transmitting.
[0105] Alternatively, the mounting member 43 may also be entirely light-transmissive. The specific configuration of the mounting member 43 is not specifically limited in this embodiment of the present application.
[0106] It should also be noted that, when the upper cover 13 includes a main body and a cover, the mounting member 43 can serve as the cover to reduce the number of components in the terminal block 100 and facilitate assembly of the terminal block 100. In this case, the mounting hole and the mounting through hole 15 can also be the same hole.
[0107] Of course, the mounting member 43 and the cover body may also be two different components. In this case, the position on the cover body opposite to the light emitting element 41 also needs to be light-transmissive.
[0108] In this case, the mounting member 43 can be disposed within the mounting cavity 11. Specifically, a fixing member can be disposed within the mounting cavity 11, the fixing member being provided with a mounting through-hole 15, and the mounting member 43 being disposed within the mounting through-hole 15. The mounting hole can be disposed on the cover body and opposite to the mounting through-hole 15, so that light emitted by the light-emitting element 41 can pass through the mounting through-hole 15 to reach the mounting hole and then be emitted.
[0109] In some embodiments, as Figures 2 to 4 As shown, the mounting cavity 11 has a cavity bottom 111. The base 10 is provided with a mounting through-hole 15 and a mounting slot 16. The mounting through-hole 15 is opposite the cavity bottom 111, and the mounting slot 16 is connected to the mounting through-hole 15. At least a portion of the mounting member 43 is inserted through the mounting through-hole 15 and embedded in the mounting cavity 11, and is engaged with the cavity wall of the mounting cavity 11. In this way, the mounting member 43 can engage with the cavity wall of the mounting cavity 11, thereby connecting the mounting member 43 to the base 10.
[0110] In this application, if Figure 4 and Figure 7 As shown, a retaining rib 432 is further provided on the side of the mounting member 43 facing the mounting groove 16. Since the retaining rib 432 is interference fit with the groove wall of the mounting groove 16, the position of the mounting member 43 can be further limited, so that after the mounting member 43 is assembled, the possibility of movement of the mounting member 43 is reduced.
[0111] It should be noted that the mounting member 43 can be engaged with the wall of the mounting cavity 11 in different ways. For example, a protrusion can be provided on the mounting member 43, and a groove can be provided on the wall of the mounting cavity 11, and the protrusion can be embedded in the groove to achieve engagement.
[0112] Alternatively, a recess may be provided on the mounting member 43 , and a boss may be provided on the cavity wall of the mounting cavity 11 , and the boss may be embedded in the recess to achieve snap connection.
[0113] In some embodiments, the first conductive member 421 may be any one of a conductive elastic member and a conductive wire. And / or, the second conductive member 422 may be any one of a conductive elastic member and a conductive wire. In this way, electrical conduction can be achieved through the conductive elastic member or the conductive wire.
[0114] It is understood that the first conductive member 421 and the second conductive member 422 are not limited to the aforementioned conductive elastic members or wires, but may also be any conductive components, such as iron wire, copper sheet, etc. The specific structures of the first conductive member 421 and the second conductive member 422 are not specifically limited in this embodiment of the present application.
[0115] The conductive elastic member may be understood as an elastic member made of a conductive material such as iron, copper, etc. The elastic member may specifically be a spring, a spring sheet, and the like.
[0116] like Figure 1 、 Figure 4 and Figure 8 As shown, when at least one of the first conductive member 421 and the second conductive member 422 is an elastic member, the elastic member is in a pre-stressed state. A limit member 17 is provided on the base 10. The limit member 17 is located on a side of the light emitting element 41 away from the first conductive member 421 and abuts against the light emitting element 41.
[0117] Since the conductive elastic member is in a pre-stressed state, the elastic member has a tendency to stretch, and has a tendency to push the light emitting element 41 to move and cause it to detach from the mounting cavity 11 .
[0118] The setting of the limiting member 17 in the present application can limit the light-emitting element 41 and apply a force toward the elastic member to the light-emitting element 41, thereby reducing the possibility of the light-emitting element 41 detaching from the installation cavity 11.
[0119] It should be noted that the solution of setting the limiting member 17 in the present application can cooperate with the elastic member to limit the position of the mounting member 43.
[0120] Of course, the aforementioned method of snapping the mounting member 43 with the cavity wall of the mounting cavity 11 and / or providing a clamping rib 432 on the mounting member 43 can also be combined to further limit the position of the mounting member 43 and improve the stability of the installation of the mounting member 43.
[0121] In the second embodiment, the indicator assembly 40 includes a sounding assembly, a connecting plate, a first conductor, and a second conductor. The connecting plate is disposed in the mounting cavity 11 and spaced apart from the contact assembly 20. The first conductor's two ends are electrically connected to the contact assembly 20 and the sounding assembly, respectively. The second conductor's two ends are electrically connected to the connecting plate and the sounding assembly, respectively.
[0122] When the contact assembly 20 is in the on state, the connection terminal 100 is energized so that the light emitting element 41 can receive electrical signals and work and emit sound. When the contact assembly 20 is in the off state, the connection terminal 100 is de-energized and the light emitting element 41 stops working.
[0123] In this way, the first conductor can connect the contact assembly 20 and the sound assembly in an electrically connected manner, and the second conductor can connect the connecting plate and the sound assembly.
[0124] According to the previous description, the contact assembly 20 is connected to the live wire. In order to enable the sound-generating assembly to be connected to different two-phase lines, the connecting plate can be an N-pole connecting plate for connecting to the neutral wire.
[0125] Based on this, the sound component can be connected to the live wire through the contact component 20 and the neutral wire through the connecting plate. When the contact component 20 is in the on state, the sound component can also receive the electrical signal and make a sound to remind the user that the current wiring component is in working state.
[0126] When the contact assembly 20 is in the disconnected state, the sound-emitting assembly does not make any sound, and the user can know that the wiring assembly is currently in an overloaded state and has stopped working.
[0127] The first conductor and the second conductor may also be any conductive component. The specific structures of the first conductor and the second conductor are not specifically limited in this embodiment of the present application. For details, please refer to the description of the first embodiment, and the present embodiment of the present application will not be repeated here.
[0128] In some embodiments, as Figure 1 、 Figure 2 and Figure 8 As shown, a first terminal 101 and a second terminal 102 may be provided in the mounting cavity 11. The first terminal 101 is electrically connected to the first connecting piece 401, and the second terminal 102 is electrically connected to the contact assembly 20. The base 10 is provided with a wiring through-hole 18 communicating with the mounting cavity 11. The first terminal 101 and the second terminal 102 are opposite to the wiring through-hole 18. The first terminal 101 and the second terminal 102 are used to electrically connect to an electrical device.
[0129] With the above arrangement, when connecting an electrical device, the connection can be made through the first terminal 101 and the second terminal 102 , thereby improving the speed of connection between the connection terminal 100 and the electrical device.
[0130] Since the wiring through hole 18 is communicated with the mounting cavity 11 , the first terminal 101 and the second terminal 102 are opposite to the wiring through hole 18 . Therefore, the wiring through hole 18 allows the first terminal 101 and the second terminal 102 to be exposed.
[0131] When an electrical device needs to be connected, the wires of the electrical device can extend into the installation cavity 11 through the wiring through-hole 18 and be electrically connected to the first terminal 101 and the second terminal 102 in the installation cavity 11 .
[0132] The first terminal 101 and the second terminal 102 can be the same as the existing terminal structure, that is, they can have a wiring baffle, an adjustment screw and a wiring frame. When it is necessary to connect a wire, the wire can be inserted into the terminal structure through the wiring frame, and then the screws are tightened to complete the connection.
[0133] At this time, the wiring through hole 18 may specifically be opposite to the wiring frame of the first terminal 101 and the wiring frame of the second terminal 102 .
[0134] In addition, the wiring through hole 18 can be a larger hole, opposite to the first terminal 101 and the second terminal 102. Figure 1 As shown, the wiring through hole 18 may also be a plurality of smaller holes, wherein one hole may be opposite to the first terminal 101 , one hole may be opposite to the second terminal 102 , and so on.
[0135] It should also be noted that the terminal block 100 of the present embodiment is not limited to having only the first terminal 101 and the second terminal 102, but may also have a third terminal 103. A second connecting piece 402 is provided inside the mounting cavity 11, and the third terminal 103 is electrically connected to the second connecting piece 402.
[0136] In this way, the first terminal 101 can be connected to the neutral wire, the second terminal 102 can be connected to the live wire, and the third terminal 103 can be connected to the ground wire, so as to adapt to electrical equipment that needs to be connected to the neutral wire, the live wire and the ground wire.
[0137] In addition, in order to protect the first terminal 101 , the second terminal 102 and the third terminal 103 , a terminal cover plate may be provided on one side of the terminal setting screw, and the terminal cover plate may be snap-fitted with the base 10 .
[0138] In addition, if Figures 1 to 4 As shown, the base 10 may further be provided with a mounting slot 180 , and the first connecting piece 401 and the second connecting piece 402 may be snapped into the mounting slot 180 to position the first connecting piece 401 and the second connecting piece 402 .
[0139] In addition, the first terminal 101, the second terminal 102 and the third component can form one terminal end of the terminal block 100. On the side opposite to the first terminal 101, the second terminal 102 and the third terminal 103, the first connecting piece 401, the static contact piece 21 and the second connecting piece 402 can extend from the inside of the base 10 to form another terminal end of the terminal block 100, so as to facilitate the connection of the terminal block 100, such as Figure 1 and Figure 9 shown.
[0140] In the embodiment of the present application, in addition to the normal function of connecting the terminal 100 to other devices, the terminal 100 also has an overload function. When the terminal 100 is overloaded, the contact assembly 20 can be switched to the disconnect state, allowing the terminal 100 to be disconnected, thereby reducing safety hazards when using the terminal 100.
[0141] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
