Description

Technical Field

[0001] This application relates to the field of terminal block technology, and more particularly to a pluggable terminal block. Background Technology

[0002] A pluggable terminal is a component used for electrical connections, typically to enable detachable connections between wires and electrical equipment. Its main function is to allow for quick disconnection or connection of circuits.

[0003] The existing plug-in terminal consists of two parts: a plug and a socket. The socket is provided with a plug-in part for plugging in the plug. The plug is connected to one end of the wire, and the socket is installed on the electrical equipment. When the plug is inserted into the socket through the plug-in part, an electrical connection can be achieved between the wire and the electrical equipment.

[0004] However, when faced with plug-in terminals located in confined spaces, workers find it difficult to apply pulling force to the plug, making it hard to remove. Furthermore, existing terminal products use single-piece plug-in terminals and screw wiring on both sides; assembling single-piece terminals cannot achieve the overall connection and disconnection of the terminal group, nor can it achieve the overall connection and disconnection of a single-sided terminal group. Utility Model Content

[0005] In view of this, this application provides a plug-in terminal that enables quick disconnection of the plug from the socket.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides a pluggable terminal block, including a socket, a plug, and an assist structure;

[0008] The socket is equipped with a socket connector and abutment structure;

[0009] The plug has a plug connector, which is engaged with the socket connector.

[0010] The assist structure includes a connecting rod and an abutment, the connecting rod being rotatably mounted on the plug, and the abutment being able to abut against the abutment structure;

[0011] During the process of the plug disengaging from the socket, the connecting rod can rotate relative to the plug, and the abutting head can fit against the abutting structure to apply a force to the plug connector away from the socket connector.

[0012] In one possible implementation, the abutment has an abutment surface, and when the plug is connected to the socket, the abutment fits against the abutment structure through the abutment surface;

[0013] The abutment has a protrusion, and during the process of the plug disengaging from the socket, the abutment abuts against the abutment structure through the protrusion.

[0014] In one possible implementation, the distance between the abutting surface and the axis of rotation of the connecting rod is less than the distance between the protrusion and the axis of rotation of the connecting rod.

[0015] In one possible implementation, the first end of the connecting rod is connected to the abutment, and the second end of the connecting rod is away from the abutment.

[0016] The distance between the first end of the connecting rod and the axis of rotation of the connecting rod is less than or equal to the distance between the second end of the connecting rod and the axis of rotation of the connecting rod.

[0017] In one possible implementation, the assist structure is provided with a fixing head, and the abutting structure is provided with a fixing groove on one side near the assist structure and an end plate on the other side.

[0018] When the plug is connected to the socket, the fixing head is inserted into the fixing groove; when the plug is disconnected from the socket, the fixing head is located outside the fixing groove.

[0019] In one possible implementation, the fixing head is provided with a connecting part, the first end of the connecting part being connected to the connecting rod, and the second end of the connecting part being connected to the fixing head.

[0020] In one possible implementation, the plug is provided with a locking element, through which the plug can be fixedly connected to the abutment structure.

[0021] In one possible implementation, an indicator structure is provided, which can be used to display the current state of the plug and the socket;

[0022] When the plug is connected to the socket, the indicator structure indicates a first state; when the plug is disconnected from the socket, the indicator structure indicates a second state.

[0023] In one possible implementation, the socket is provided with an indicator structure that can be used to display the current state of the plug and the socket;

[0024] When the plug is connected to the socket, the indicator structure indicates a first state; when the plug is disconnected from the socket, the indicator structure indicates a second state.

[0025] In one possible implementation, the socket is provided with a display port; the indicator structure includes a first indicator part and a second indicator part connected to each other, the first indicator part and the second indicator part being movable relative to the socket along a first direction;

[0026] The plug can be inserted into the socket in the second direction; the plug can push the first indicator and the second indicator to move in the first direction;

[0027] When the plug is connected to the socket, the indicator structure is in a first position, and the first indicator part can be exposed through the display port; when the plug is disconnected from the socket, the indicator structure is in a second position, and the second indicator part can be exposed through the display port.

[0028] This application provides a plug-in terminal block, including a socket, a plug, and an auxiliary structure. The socket is provided with a socket connector and an abutment structure, the plug has a plug connector, and the auxiliary structure includes a connecting rod and an abutment joint.

[0029] The plug and socket connectors are inserted into each other to achieve electrical connection between the plug and the socket. At this time, the abutment and the abutment structure are in contact. When it is necessary to disconnect the plug from the socket, the connecting rod is rotated, which causes the abutment and the abutment structure to come into contact and interfere. The abutment presses down on the abutment structure, and the abutment structure applies an upward reaction force to the abutment and the plug, thereby releasing the engagement between the plug and socket connectors and enabling the quick disconnection of the plug and socket on one side of the terminal product.

[0030] Compared to existing plug-in terminals, the plug-in terminal provided in this application improves work efficiency by adding an assistive structure to enable quick disconnection of the plug and socket on one side of the terminal product. Attached Figure Description

[0060] A pluggable terminal is a component used for electrical connections, typically to enable detachable connections between wires and electrical equipment. Its main function is to allow for quick disconnection or connection of circuits.

[0061] The existing plug-in terminal consists of two parts: a plug and a socket. The socket is provided with a plug-in part for plugging in the plug. The plug is connected to one end of the wire, and the socket is installed on the electrical equipment. When the plug is inserted into the socket through the plug-in part, an electrical connection can be achieved between the wire and the electrical equipment.

[0062] However, when faced with plug-in terminals located in confined spaces, workers find it difficult to apply pulling force to the plug, making it hard to remove. Furthermore, existing terminal products use single-piece plug-in terminals and screw wiring on both sides; assembling single-piece terminals cannot achieve the overall connection and disconnection of the terminal group, nor can it achieve the overall connection and disconnection of a single-sided terminal group.

[0063] Based on this, the present application provides a plug-in terminal, including a socket, a plug, and an auxiliary structure, wherein the socket is provided with a socket connector and an abutment structure, the plug has a plug connector, and the auxiliary structure includes a connecting rod and an abutment joint.

[0064] The plug and socket connectors are inserted into each other to achieve electrical connection between the plug and the socket. At this time, the abutment and the abutment structure are in contact. When it is necessary to disconnect the plug from the socket, the connecting rod is rotated, which causes the abutment and the abutment structure to come into contact and interfere. The abutment presses down on the abutment structure, and the abutment structure applies an upward reaction force to the abutment and the plug, thereby releasing the engagement between the plug and socket connectors and enabling the quick disconnection of the plug and socket on one side of the terminal product.

[0065] Compared to existing plug-in terminals, the plug-in terminal provided in this application improves work efficiency by adding an assistive structure to enable quick disconnection of the plug and socket on one side of the terminal product.

[0066] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0067] Reference Figures 1 to 4 As shown, this application embodiment provides a plug-in terminal, including a socket 100, a plug 200 and an assist structure 300; the socket 100 is provided with a socket connector 110 and an abutment structure 120; the plug 200 has a plug connector 210, which is plugged into and cooperates with the socket connector 110.

[0068] In practical implementation, plug 200 connects to one end of the wire, while socket 100 is installed on the electrical equipment. When plug connector 210 and socket connector 110 are plugged in, plug 200 and socket 100 act as an intermediate bridge to achieve electrical connection between the wire and the electrical equipment. Plug connector 210 is composed of multiple plug connector bodies, enabling plug 200 to have the function of overall connection and disconnection.

[0069] The assist structure 300 includes a connecting rod 310 and an abutment 320 connected to each other. The connecting rod 310 is rotatably mounted on the plug 200, and the abutment 320 abuts against the abutment structure 120. During the process of the plug 200 disengaging from the socket 100, the connecting rod 310 can rotate relative to the plug 200, and the abutment 320 can fit against the abutment structure 120 to apply a force away from the socket connector 110 to the plug connector 210.

[0070] In practical implementation, two assistive structures 300 are used, one on each side of the plug 200. When the plug 200 needs to be disengaged from the socket 100, the connecting rod 310 is rotated, causing the abutment 320 to come into contact with the abutment structure 120 and interfere with it. The abutment 320 presses down on the abutment structure 120, and the abutment structure 120 applies an upward reaction force to the abutment 320 and the plug 200, releasing the engagement between the plug connector 210 and the socket connector 110, thus achieving rapid disengagement of the plug 200 from the socket 100. Of course, the number of assistive structures 300 can be one or three, and the specific number of assistive structures 300 can be designed according to actual installation requirements, which will not be elaborated here.

[0071] Compared to the plug-in terminals in the prior art, the plug-in terminals provided in this application improve work efficiency by adding an assist structure 300 to enable the plug 200 to quickly disconnect from the socket 100.

[0072] Reference Figures 1 to 3 As shown, in some embodiments, the abutment 320 has an abutment surface 321. When the plug 200 is connected to the socket 100, the abutment 320 fits against the abutment structure 120 through the abutment surface 321. The abutment 320 has a protrusion 322. During the process of the plug 200 being disengaged from the socket 100, the abutment 320 abuts against the abutment structure 120 through the protrusion 322.

[0073] Furthermore, the distance between the contact surface 321 and the axis of rotation of the connecting rod 310 is less than the distance between the protrusion 322 and the axis of rotation of the connecting rod 310.

[0074] Specifically, when the plug connector 210 and the socket connector 110 are plugged in and engaged, that is, when the plug 200 and the socket 100 are electrically connected, the abutment 320 is in contact with the abutment structure 120 through the abutment surface 321. At this time, the abutment surface 321 can not only increase the contact area between the plug 200 and the socket 100, making the plugging relationship between the two more stable, but also limit the insertion distance of the plug 200. That is, when the abutment surface 321 is in contact with the abutment structure 120, it means that the plug 200 has been plugged in.

[0075] When it is necessary for the plug 200 to be disengaged from the socket 100, the connecting rod 310 is rotated, which causes the protrusion 322 on the abutment 320 to interfere with the abutment structure 120. The protrusion 322 presses down on the abutment structure 120, and the abutment structure 120 applies an upward reaction force to the protrusion 322 and the plug 200, thereby releasing the cooperation between the plug connector 210 and the socket connector 110, and realizing the rapid disengagement of the plug 200 from the socket 100.

[0076] Reference Figures 1 to 3 As shown, in some embodiments, the first end of the connecting rod 310 is connected to the abutment 320, and the second end of the connecting rod 310 is away from the abutment 320; the distance between the first end of the connecting rod 310 and the axis of rotation of the connecting rod 310 is less than or equal to the distance between the second end of the connecting rod 310 and the axis of rotation of the connecting rod 310.

[0077] Specifically, when it is necessary for the plug 200 to detach from the socket 100, the second end of the connecting rod 310 is rotated, which in turn causes the first end of the connecting rod 310 to rotate together with the abutment 320 until the abutment 320 and the abutment structure 120 come into contact and interfere. The abutment 320 presses down on the abutment structure 120, and the abutment structure 120 applies an upward reaction force to the abutment 320 and the plug 200, thereby releasing the cooperation between the plug connector 210 and the socket connector 110, and realizing the rapid detachment of the plug 200 from the socket 100.

[0078] Meanwhile, the distance between the first end of the connecting rod 310 and the axis of rotation of the connecting rod 310 is less than or equal to the distance between the second end of the connecting rod 310 and the axis of rotation of the connecting rod 310. According to the lever principle, a smaller force is used to rotate the second end of the connecting rod 310 to generate a larger thrust at the first end of the connecting rod 310, which pushes the abutment 320 to contact the abutment structure 120 and cause interference. Compared with other design forms of the connecting rod 310, it is more labor-saving.

[0079] Reference Figures 1 to 3As shown, in some embodiments, the assist structure 300 is provided with a fixing head 340, and the abutment structure 120 is provided with a fixing groove 121 on one side near the assist structure 300, and an end plate on the other side; when the plug 200 is connected to the socket 100, the fixing head 340 is inserted into the fixing groove 121; when the plug 200 is disconnected from the socket 100, the fixing head 340 is located outside the fixing groove 121.

[0080] Specifically, when the plug connector 210 and the socket connector 110 are plugged in and engaged, that is, when the plug 200 and the socket 100 are electrically connected, the connecting rod 310 is rotated clockwise, thereby driving the fixing head 340 to insert into the fixing groove 121 opened on the abutment structure 120. The fixing head 340 and the fixing groove 121 cooperate with each other to fix the current position of the plug 200, that is, the state in which the plug 200 and the socket 100 are electrically connected, so as to prevent the plug 200 from accidentally falling off the socket 100 during use, which would cause the power supply to the electrical equipment to be interrupted.

[0081] Furthermore, refer to Figures 1 to 3 As shown, in some embodiments, the fixing head 340 is provided with a connecting part 330, the first end of the connecting part 330 is connected to the connecting rod 310, and the second end of the connecting part 330 is connected to the fixing head 340.

[0082] In a specific implementation, a connecting part 330 is added to the assist structure 300. The fixing head 340 is connected to the connecting rod 310 through the connecting part 330. The connecting part 330 can extend the distance that the fixing head 340 is inserted into the fixing groove 121, thereby making the electrical connection between the plug 200 and the socket 100 more stable.

[0083] Reference Figures 1 to 3 As shown, in some embodiments, the plug 200 is provided with a locking member 400, and the plug 200 can be fixedly connected to the abutment structure 120 by means of the locking member 400.

[0084] In practical implementation, the locking element 400 is set as a fastening bolt, and the number of locking elements 400 is set to two, with the two locking elements 400 respectively located on both sides of the plug 200. The plug 200 has a through hole, and the socket 100 has a threaded groove. The locking element 400 passes through the through hole and engages with the threaded groove to fix the relative position of the plug 200 and the socket 100. This not only facilitates the assembly between the plug 200 and the socket 100, but also ensures a reliable connection between the plug 200 and the socket 100.

[0085] Meanwhile, the locking element 400 and the fixing head 340 cooperate to achieve multi-level fixation of the current position of the plug 200, that is, the state of electrical connection between the plug 200 and the socket 100. This provides secondary protection between the plug 200 and the socket 100, preventing the plug 200 from accidentally falling off the socket 100 during use and causing power interruption to the electrical equipment. Of course, the number of locking elements 400 can be set to one or three. The specific number of locking elements 400 can be designed according to actual installation requirements, which will not be elaborated here.

[0086] Reference Figures 1 to 4 As shown, in some embodiments, an indicator structure 500 is provided, which can be used to display the current state of the plug 200 and the socket 100; when the plug 200 is connected to the socket 100, the indicator structure 500 indicates a first state; when the plug 200 is disconnected from the socket 100, the indicator structure 500 indicates a second state.

[0087] Furthermore, the socket 100 is provided with an indicator structure 500, which can be used to display the current state of the plug 200 and the socket 100; when the plug 200 is connected to the socket 100, the indicator structure 500 indicates the first state; when the plug 200 is disconnected from the socket 100, the indicator structure 500 indicates the second state.

[0088] In practical implementation, an indicator structure 500 is added. The indicator structure 500 can display the connection status between the plug 200 and the socket 100 to the staff in real time, that is, whether the plug 200 and the socket 100 are properly plugged in and whether the plug 200 and the socket 100 are completely disconnected. This avoids the plug 200 from the socket 100 accidentally falling off during use, which would cause power outage to the electrical equipment; and avoids the plug 200 being pulled before it is completely disconnected from the socket 100, which would cause damage to the plug connector 210 and the socket connector 110.

[0089] Furthermore, refer to Figures 1 to 4 As shown, in some embodiments, the socket 100 is provided with a display port 130; the indicator structure 500 includes a first indicator part 510 and a second indicator part 520 connected to each other, the first indicator part 510 and the second indicator part 520 being movable relative to the socket 100 along a first direction; the plug 200 being able to be inserted into the socket 100 along a second direction; the plug 200 being able to push the first indicator part 510 and the second indicator part 520 to move along the first direction; when the plug 200 is connected to the socket 100, the indicator structure 500 is in a first position, and the first indicator part 510 is exposed through the display port 130; when the plug 200 is disconnected from the socket 100, the indicator structure 500 is in a second position, and the second indicator part 520 is exposed through the display port 130.

[0090] In practical implementation, the top of both the first indicator 510 and the second indicator 520 is provided with a color block, which can be green and red, or other colors. Just make sure that the color blocks on the first indicator 510 and the second indicator 520 are different colors, so as to facilitate the installation personnel and customers to identify the installation status. This will not be described in detail here.

[0091] When the plug connector 210 is in the second direction (e.g.) Figure 2 When the plug 200 is inserted into the socket connector 110 in the X direction (as shown in the image), that is, when the plug 200 and socket 100 are electrically connected, the plug connector 210 will push the indicator structure 500 along the first direction (e.g., the X direction). Figure 2 The indicator 500 moves to the first position (in the Y direction) and compresses the elastic element between the indicator structure 500 and the socket 100. At this time, after being subjected to the elastic force from the elastic element, the indicator structure 500 has a tendency to move from the first position back to the second position. The color block on the top of the first indicator 510 will be exposed through the display port 130 to indicate that the plug 200 and the socket 100 have been plugged in. When the plug 200 and the socket 100 are disconnected, the indicator structure 500 returns to the second position, and the color block on the top of the second indicator 520 will be exposed through the display port 130 to indicate that the plug 200 and the socket 100 have been completely disconnected.

[0092] In this embodiment, the indicator structure 500 is disposed on the socket 100 at a position corresponding to each socket connector body. In some other embodiments, the indicator structure 500 may also be disposed on a socket terminal group formed by assembling each socket connector body, and multiple socket terminal groups may be combined to form a socket. In some other embodiments, the indicator structure 500 may also be disposed on a plug terminal group formed by assembling plug connectors, and multiple plug terminal groups may be combined to form a plug.

[0093] In this embodiment, the number of terminal combinations of the socket connector 110 and the plug connector 210 is 4. In some embodiments, the number of terminal combinations of the socket connector 110 and the plug connector 210 can be flexibly adjusted according to actual needs, specifically 2, 6, 8, etc.

[0094] In this embodiment, the plug 200 and the socket 100 are configured to be plugged in and unplugged from one side. In some embodiments, the plug 200 and the socket 100 may also be configured to be plugged in and unplugged from both sides according to actual installation requirements, so as to realize the electrical connection between the wire and the electrical equipment.

[0095] In this embodiment, the pluggable terminal can be provided with pluggable bridging components or screw-type bridging components on both sides to achieve bridging between adjacent single terminals, or to achieve cross-connection between single terminals.

[0096] In this embodiment, the socket 100 is also provided with a slider assembly to realize the connection and disconnection function of the single terminal.

[0097] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in the embodiments of this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in the embodiments of this application can be achieved, and this document does not impose any restrictions.

[0098] The specific embodiments described above do not constitute a limitation on the scope of protection of the embodiments of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors.
