Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a terminal block. Background Technology

[0002] Terminal blocks are a common type of connection component that have been widely used in various fields such as communication products, industrial equipment for device integration, power industry, and industrial control. They not only improve the reliability and safety of power systems, but also enable industrial equipment to achieve a high degree of automation.

[0003] Terminal blocks typically include an insulating substrate, conductive springs, and a current carrier. The insulating substrate has an insertion channel for wires to be inserted. The conductive springs and current carriers are installed inside the insulating substrate, and they clamp the wires and provide electrical conductivity.

[0004] However, in order to install the conductive spring and the current carrier into the insulating base, an opening is provided on one side of the insulating base. This often causes the wire to tilt and protrude from the insulating base after the wire is inserted, thus affecting the safety of use. Moreover, the conductive spring may also come out or shift from the opening, affecting the stability and reliability of use.

[0005] To address the aforementioned issues, existing technologies employ a sheet-like barrier extending additionally from the side of the fluid carrier to limit the conductive spring and wire. To facilitate production, this barrier is typically made of the same material as the fluid carrier, namely conductive metal, which significantly increases production costs. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a terminal block that uses a first stop structure in the form of a strip to limit and stop the external conductive parts and the clamping elastic parts, ensuring stability and reliability during use, and greatly reducing production costs.

[0007] To achieve the above objectives, the present invention employs the following technical solution:

[0008] A terminal block, comprising:

[0009] An insulating substrate having an assembly space and an insertion channel connected to the assembly space for inserting an external conductive component into the assembly space, wherein the insertion channel has an insertion port at one end away from the assembly space and a communication port at the other end connected to the assembly space.

[0010] A clamping elastic element is disposed within the assembly space;

[0011] A current-carrying element disposed within the assembly space includes a conductive clamping wall capable of clamping an external conductive element between the conductive clamping wall and an elastic clamping segment of a clamping elastic element. The elastic clamping segment is movable relative to the conductive clamping wall to move closer to or away from the conductive clamping wall. The clamping elastic element has a tendency to reset the elastic clamping segment toward the conductive clamping wall when the elastic clamping segment moves away from the conductive clamping wall.

[0012] And a first stop structure, the first stop structure being used to restrict the external conductive element and / or clamping elastic element from leaving the assembly space, the first fixed end of the first stop structure being connected to the conductive clamping wall, the first free end extending in the direction of the clamping elastic element, and the first stop structure being configured as a strip structure.

[0013] Using the above technical solution, during use, the user can operate the clamping elastic member to move the elastic member clamping segment away from the conductive clamping wall. At this time, an external conductive member, such as a cable, can be inserted between the conductive clamping wall and the elastic member clamping segment through the insertion channel. When the external force applied to the clamping elastic member is removed, the clamping elastic member, under its elastic action, will reset the elastic member clamping segment towards the conductive clamping wall to clamp the external conductive member between the conductive clamping wall and the elastic member clamping segment.

[0014] Due to the first stop structure, the first stop structure can limit and stop the external conductive component inserted between the conductive clamping wall and the elastic clamping section, preventing the external conductive component from detaching from the assembly space; and / or the first stop structure can limit and stop the clamping elastic component, preventing the clamping elastic component from detaching from the assembly space, ensuring the reliability and stability of the terminal block.

[0015] In the above structure, the first stop structure is configured as a strip structure, which reduces the use of metal materials and greatly reduces production costs compared to the sheet metal structure in the prior art.

[0016] Specifically, the insulating substrate has an assembly opening on one side perpendicular to the axis of the insertion channel, which communicates with the assembly space; during production and installation, the current-carrying component and the clamping elastic component are installed into the assembly space through the assembly opening; the first stop structure is disposed on the side of the assembly opening, and the first stop structure is used to restrict the external conductive component and / or the clamping elastic component from leaving the assembly space through the assembly opening.

[0017] Furthermore, the current-carrying component includes a current-carrying substrate, and one end of the conductive clamping wall and one end of the current-carrying substrate are connected by a bending structure.

[0018] By adopting the above technical solution, the current-carrying component is made more reasonable. Specifically, the conductive clamping wall is set perpendicular to the current-carrying substrate, and the current-carrying substrate and the conductive clamping wall are integrally formed.

[0019] Furthermore, the first free end of the first stop structure is disposed at least across the communication port on one side facing the conductive clamping wall.

[0020] By adopting the above technical solution, the structure of the first stop structure is made more reasonable, so that it can play a better role in limiting and stopping.

[0021] In some embodiments, the first free end of the first stop structure is provided across both sides of the communication port, and the above structure enables the first stop structure to play a better limiting and stopping role.

[0022] In some embodiments, the first free end of the first stop structure is provided only across the communication port on the side facing the conductive clamping wall. The above structure makes the length of the first stop structure relatively short. When the clamping elastic member is installed, the clamping elastic member can be installed in a way that deforms at a small angle, avoiding large angle deformation that would weaken its elasticity and ensuring the reliability of the clamping elastic member.

[0023] Furthermore, in some embodiments, the terminal block includes a second stop structure, the second fixed end of the second stop structure being connected to the current-carrying substrate, the second free end of the second stop structure extending in the direction of the communication port, and the second stop structure being configured as a strip structure.

[0024] The above technical solution makes the wiring terminal more reasonable. The first stop structure and the second stop structure can cooperate to play a limiting and stopping role. In particular, for the limiting and stopping of the clamping elastic member, when the clamping segment of the elastic member moves away from the conductive clamping wall, it can be limited and stopped by the first stop structure at the beginning and by the second stop structure at the end.

[0025] The second stop structure can compensate for the relatively short length of the first stop structure, thus ensuring reliability;

[0026] In the above structure, the second stop structure is configured as a strip structure, which can reduce material usage and greatly reduce production costs; specifically, the second stop structure is disposed on the assembly opening side.

[0027] Furthermore, the first stop structure is made of a rigid material.

[0028] By adopting the above technical solution, the first stop structure becomes more reasonable and reliable. The insertion of the external conductive component will apply force to the first stop structure. When the external conductive component tends to come out during the clamping process, it will also apply force to the first stop structure. When the clamping elastic component tends to come out due to its own deformation, it will also apply force to the first stop structure. The above structure enables the first stop structure to withstand higher external forces and to maintain its shape or prevent damage, thus ensuring the limiting and stopping effect of the first stop structure.

[0029] Furthermore, the extension direction of the first free end of the first stop structure is perpendicular to the central axis of the communication port.

[0030] By adopting the above technical solution, the first stop structure becomes more reasonable.

[0031] Furthermore, the first stop structure includes a first stop free arm and a first stop connecting arm. One end of the first stop connecting arm is formed as the first fixed end, and the other end is connected to one end of the first stop free arm. The other end of the first stop free arm is formed as the first free end. The first stop connecting arm is bent so that the first stop free arm extends in the direction of the clamping elastic member.

[0032] By adopting the above technical solution, the first stop structure becomes more reasonable and easier to manufacture.

[0033] The first stop structure is formed by bending a portion of the conductive clamping wall.

[0034] By adopting the above technical solution, the first stop structure and the conductive clamping wall are more reasonable, which not only facilitates actual production, but also ensures that the connection between the first stop structure and the conductive clamping wall is more stable and reliable.

[0035] Because the conductive clamping wall is made of a conductive metal material, the rigidity of the first stop structure can be guaranteed.

[0036] Furthermore, the second stop structure is made of a rigid material.

[0037] By adopting the above technical solution, the second stop structure becomes more reasonable and reliable. The insertion of the external conductive component will apply force to the second stop structure. When the external conductive component tends to come out during the clamping process, it will also apply force to the second stop structure. When the clamping elastic component tends to come out due to its own deformation, it will also apply force to the second stop structure. The above structure enables the second stop structure to withstand higher external forces and maintain its shape without deformation or damage, thus ensuring the limiting and stopping effect of the second stop structure.

[0038] Furthermore, the second stop structure includes a second stop free arm and a second stop connecting arm. One end of the second stop connecting arm is formed as the second fixed end, and the other end is connected to one end of the second stop free arm. The other end of the second stop free arm is formed as the second free end. The second stop connecting arm is bent so that the second stop free arm extends along the direction of the communication port.

[0039] By adopting the above technical solution, the second stop structure becomes more reasonable and easier to manufacture.

[0040] Furthermore, the second stop structure is formed by bending a portion of the current-carrying matrix.

[0041] By adopting the above technical solution, the second stop structure and the current-carrying substrate are more reasonable, which not only facilitates actual production, but also ensures that the connection between the second stop structure and the current-carrying substrate is more stable and reliable.

[0042] Because the current-carrying substrate is made of a conductive metal material, the rigidity of the second stop structure can be guaranteed.

[0043] Furthermore, the side of the assembly space opposite to the connecting port is referred to as the bottom surface of the assembly space;

[0044] In some embodiments, the first stop structure is spaced apart from the side of the face facing the connection port, and the terminal block includes a third stop structure for restricting the external conductive element and / or clamping elastic element from disengaging from the assembly space, the third stop structure being located between the side of the first stop structure facing the connection port and the face of the connection port.

[0045] And / or the first stop structure is spaced apart from the side of the assembly space facing the bottom surface of the assembly space, and the terminal block includes a fourth stop structure for restricting the external conductive element and / or clamping elastic element from leaving the assembly space, and the fourth stop structure is spaced apart from the side of the first stop structure facing the bottom surface of the assembly space.

[0046] By adopting the above technical solution, the third stop structure and / or the fourth stop structure can limit and stop the external conductive component and / or the clamping elastic component, preventing the external conductive component and / or the clamping elastic component from detaching from the assembly space, and ensuring the reliability and stability of the wiring terminal; specifically, when the third stop structure is provided, the third stop structure is provided on the assembly opening side, and when the fourth stop structure is provided, the fourth stop structure is provided on the assembly opening side.

[0047] Furthermore, when the third stop structure is provided: the side of the third stop structure facing the clamping elastic member is coplanar with the side of the first stop structure facing the clamping elastic member.

[0048] By adopting the above technical solution, the third stop structure and the first stop structure are made more reasonable, avoiding the oblique part of the third stop structure and the first stop structure from affecting the insertion of the external conductive component and the movement of the elastic clamping section, thus ensuring smooth insertion of the external conductive component and smooth movement of the elastic clamping section.

[0049] Furthermore, in the case where the third stop structure is provided: the third stop structure is configured as a sheet structure, and the third stop structure is made of plastic.

[0050] By adopting the above technical solution, the third stop structure is more reasonable, and the sheet-like structure of the third stop structure can have a better stopping effect; moreover, since the third stop structure is made of plastic, the cost can be greatly reduced compared with metal materials.

[0051] Since the third stop structure is made of plastic, its endurance on the side edge away from the connection opening is relatively poor. The first stop structure is located on the side of the third stop structure away from the connection opening to withstand external forces and alleviate the force on the side edge of the third stop structure away from the connection opening. The structure is reasonable and reliable.

[0052] Furthermore, when the third stop structure is provided: the third stop structure extends towards the conductive clamping wall from the side facing the conductive clamping wall to approach or cross the communication port from the side facing the conductive clamping wall; the third stop structure extends away from the conductive clamping wall from the side away from the conductive clamping wall to approach or cross the communication port from the side away from the conductive clamping wall.

[0053] By adopting the above technical solution, the structure of the third stop structure is made more reasonable, so that it can play a better role in limiting and stopping.

[0054] Furthermore, in the case where the third stop structure is provided: a first clamping arm passage is provided between the side of the third stop structure facing the conductive clamping wall and the assembly space for the conductive clamping wall to pass through.

[0055] By adopting the above technical solution, the third stop structure is more reasonable and facilitates actual production and installation. When installing the current-carrying component, the conductive clamping wall can pass through the first clamping arm opening and be installed into the assembly space, thus avoiding the impact of the third stop structure on the installation of the current-carrying component.

[0056] Furthermore, when the fourth stop structure is provided: the side of the fourth stop structure facing the clamping elastic member is coplanar with the side of the first stop structure facing the clamping elastic member.

[0057] By adopting the above technical solution, the fourth stop structure and the first stop structure are made more reasonable, avoiding the oblique part of the fourth stop structure and the first stop structure from affecting the insertion of the external conductive component and the movement of the elastic clamping section, thus ensuring smooth insertion of the external conductive component and smooth movement of the elastic clamping section.

[0058] Furthermore, in the case where the fourth stop structure is provided: the fourth stop structure is configured as a sheet structure, and the fourth stop structure is made of plastic.

[0059] By adopting the above technical solution, the fourth stop structure is more reasonable, and the sheet-like structure of the fourth stop structure can have a better stopping effect; moreover, since the fourth stop structure is made of plastic, the cost can be greatly reduced compared with metal materials.

[0060] Since the fourth stop structure is made of plastic, its resistance to force on the side edge facing the connection opening is relatively poor. The first stop structure is located on the side of the fourth stop structure facing the connection opening to withstand external forces and alleviate the force on the side edge of the fourth stop structure facing the connection opening. The structure is reasonable and reliable.

[0061] Furthermore, when the fourth stop structure is provided: the fourth stop structure extends towards the conductive clamping wall from the side facing the conductive clamping wall to approach or cross the communication port from the side facing the conductive clamping wall; the fourth stop structure extends away from the conductive clamping wall from the side away from the conductive clamping wall to approach or cross the communication port from the side away from the conductive clamping wall.

[0062] By adopting the above technical solution, the structure of the fourth stop structure is made more reasonable, so that it can play a better role in limiting and stopping.

[0063] Furthermore, in the case where the fourth stop structure is provided: a second clamping arm passage is provided between the side of the fourth stop structure facing the conductive clamping wall and the assembly space for the conductive clamping wall to pass through.

[0064] By adopting the above technical solution, the fourth stop structure is more reasonable and facilitates actual production and installation. When installing the current-carrying component, the conductive clamping wall can pass through the second clamping arm through-hole and be installed into the assembly space, thus avoiding the impact of the fourth stop structure on the installation of the current-carrying component.

[0065] Furthermore, the current-carrying substrate of the current-carrying component is provided with an abutment portion, and the clamping elastic component includes an installation mating section and an intermediate connecting section. The intermediate connecting section is disposed between the installation mating section and the elastic component clamping section, and both ends of the intermediate connecting section are respectively connected to one end of the installation mating section and one end of the elastic component clamping section. The other end of the installation mating section abuts against the side of the abutment portion facing the conductive clamping wall.

[0066] By adopting the above technical solution, the clamping elastic element and the current-carrying substrate are more reasonable. The abutment part and the mounting mating section can not only realize the positioning of the clamping elastic element on the current-carrying fluid, but also provide support force for the mounting mating section of the clamping elastic element.

[0067] Furthermore, a portion of the current-carrying matrix is ​​bent to form the abutment portion.

[0068] By adopting the above technical solution, the abutment part is made more reasonable, which not only facilitates actual production, but also facilitates the abutment part to abut against the mounting end of the clamping elastic element.

[0069] Furthermore, the abutment portion is located between the first stop structure and the inner wall of the assembly space opposite to the first stop structure.

[0070] By adopting the above technical solution, the setting of the abutment part is made more reasonable; specifically, the abutment part is bent at 90 degrees relative to the current-carrying substrate.

[0071] The abutment is located on the longitudinal centerline of the fluid-carrying material, and the first stop structure is located on one side of the longitudinal centerline of the fluid-carrying material; when the second stop structure is provided, the second stop structure is located on one side of the longitudinal centerline of the fluid-carrying material, and the second stop structure and the first stop structure are located on the same side of the longitudinal centerline of the fluid-carrying material.

[0072] Furthermore, the middle connecting section of the clamping elastic element has an arc-shaped structure.

[0073] The above technical solution makes the intermediate connection segment more reasonable.

[0074] Furthermore, the terminal block also includes an elastic support, and an elastic intermediate slot matching the intermediate connecting section is formed between the elastic support and the inner wall of the assembly space, and the intermediate connecting section is inserted into the elastic intermediate slot.

[0075] By adopting the above technical solution, the insulating substrate is made more reasonable, and the middle slot of the elastic element facilitates the positioning and installation of the clamping elastic element, ensuring its stable and reliable operation.

[0076] Specifically, the side of the assembly space opposite to the assembly opening is referred to as the assembly opening opposite side, and the assembly opening opposite side protrudes towards the assembly opening side to form the elastic support platform.

[0077] Furthermore, when the third stop structure is provided: the side of the third stop structure facing the surface where the communication port is located is connected to the insulating substrate; specifically, the side of the third stop structure facing the surface where the communication port is located is connected to the side of the assembly opening near the surface where the communication port is located.

[0078] By adopting the above technical solution, the third stop structure is made more reasonable, so as to realize the connection between the third stop structure and the insulating substrate.

[0079] Furthermore, if the third stop structure is provided: the third stop structure is integrally formed with the insulating substrate.

[0080] The above technical solution not only facilitates actual production, but also ensures the reliability of the connection of the third stop structure; and both the third stop structure and the insulating substrate are made of plastic, which facilitates the integral molding of the two.

[0081] Furthermore, in the case where the fourth stop structure is provided: the side of the fourth stop structure facing the bottom surface of the assembly space is connected to the insulating substrate; specifically, the side of the fourth stop structure facing the bottom surface of the assembly space is connected to the side of the assembly opening near the bottom surface of the assembly space; or the wiring terminal is provided with a stop structure connecting part at the fourth stop structure, and the fourth stop structure is connected to the stop structure connecting part.

[0082] By adopting the above technical solution, the fourth stop structure is made more reasonable, so as to realize the connection between the fourth stop structure and the insulating substrate; specifically, the assembly opening protrudes to the side opposite to the assembly opening to form the stop structure connection part.

[0083] Furthermore, if the fourth stop structure is provided: the fourth stop structure is integrally formed with the insulating substrate.

[0084] The above technical solution not only facilitates actual production, but also ensures the reliability of the connection of the fourth stop structure; and both the fourth stop structure and the insulating substrate are made of plastic, which facilitates the integral molding of the two.

[0085] Furthermore, when the fourth stop structure is connected to the insulating substrate through the stop structure connecting part, the stop structure connecting part is located on the side of the fourth stop structure away from the conductive clamping wall, or the stop structure connecting part is located on the side of the fourth stop structure facing the bottom surface of the assembly space.

[0086] By adopting the above technical solution, the connection part of the stop structure is made more reasonable, avoiding its impact on the insertion of external conductive parts and the movement of the elastic clamping section.

[0087] Furthermore, when the fourth stop structure is connected to the insulating substrate through the stop structure connecting part, and the stop structure connecting part is located on the side of the fourth stop structure away from the conductive clamping wall, an elastic element mounting port is provided between the side of the fourth stop structure facing the communication port and the stop structure connecting part.

[0088] By adopting the above technical solution, the setting of the elastic element mounting port facilitates the installation of the elastic element clamping segment into the assembly space through the elastic element mounting port during the installation of the clamping elastic element.

[0089] Furthermore, the terminal block also includes an elastic element limiting boss, which is spaced apart from the conductive clamping wall on the side facing the conductive clamping wall, and the elastic element limiting boss is located on the movement trajectory of the elastic element clamping segment.

[0090] By adopting the above technical solution, the insulating substrate is made more reasonable, and the setting of the elastic element limiting boss can limit the maximum movement of the elastic element clamping section, avoid the excessive deformation of the clamping elastic element leading to a weakening of its elasticity, and ensure the reliability of the clamping elastic element.

[0091] Specifically, the assembly opening protrudes laterally to form the elastic element limiting boss.

[0092] Furthermore, along the direction from the bottom surface of the assembly space to the communication port, the side of the elastic element limiting boss facing the conductive clamping wall gradually tilts away from the conductive clamping wall.

[0093] By adopting the above technical solution, the elastic element limiting boss is made more reasonable, which makes it easier for it to more reliably limit the elastic element clamping section.

[0094] Furthermore, the elastic element limiting boss is spaced apart from the bottom surface of the assembly space, and the distance between the elastic element limiting boss and the bottom surface of the assembly space is greater than or equal to the thickness at the corresponding position of the current-carrying substrate.

[0095] By adopting the above technical solution, the setting of the elastic element limiting boss is more reasonable, and space is reserved for the installation of the current-carrying substrate, that is, the current-carrying substrate can be installed between the elastic element limiting boss and the bottom surface of the assembly space.

[0096] Furthermore, when the fourth stop structure is provided: the fourth stop structure is spaced apart from the bottom surface of the assembly space, and the distance between the fourth stop structure and the bottom surface of the assembly space is greater than or equal to the thickness at the corresponding position of the current-carrying substrate, and the fourth stop structure is connected to the insulating substrate through the stop structure connecting part.

[0097] By adopting the above technical solution, the fourth stop structure is set more reasonably, reserving space for the installation of the current-carrying substrate, that is, the current-carrying substrate can be installed between the fourth stop structure and the bottom surface of the assembly space.

[0098] Furthermore, the elastic element limiting boss is disposed on the side of the fourth stop structure away from the conductive clamping wall, and the elastic element limiting boss is formed as the connecting part of the stop structure.

[0099] By adopting the above technical solution, the terminal structure is more reasonable, and the elastic element limiting boss is formed as the stop structure connection part, which can simplify the overall structure; and since the side of the elastic element limiting boss facing the conductive clamping wall gradually tilts away from the conductive clamping wall, it is convenient to form the elastic element mounting port.

[0100] Furthermore, the terminal block includes a button movably disposed on the insulating substrate, and the button, during operation, can drive the elastic clamping segment to move away from the conductive clamping wall.

[0101] By adopting the above technical solution, the wiring terminal is more reasonable. The button is designed so that the operator can drive the elastic clamping section to move away from the conductive clamping wall by operating the button. The elastic clamping section is also driven more stably and reliably by the button.

[0102] Furthermore, the button is located on the side of the elastic clamping section facing the insertion port, and the direction of movement of the button relative to the insulating substrate is parallel to the axis of the insertion channel.

[0103] By adopting the above technical solution, the button is set more reasonably, enabling it to stably and reliably drive the elastic clamping segment to move away from the conductive clamping wall.

[0104] Furthermore, the insertion channel is provided in multiple ways, and the number of the conductive clamping wall, the clamping elastic member, the first stop structure and the abutment part are matched with the number of the insertion channel and correspond one-to-one.

[0129] A current-carrying component 2 is disposed within the assembly space 101. The current-carrying component 2 includes a conductive clamping wall 201. The conductive clamping wall 201 and the elastic clamping segment 301 of the clamping elastic component 3 are capable of clamping an external conductive component. The elastic clamping segment 301 is movable relative to the conductive clamping wall 201 to move closer to and away from the conductive clamping wall 201. The clamping elastic component 3 has a tendency to reset the elastic clamping segment 301 toward the conductive clamping wall 201 when the elastic clamping segment 301 moves away from the conductive clamping wall 201.

[0130] And a first stop structure 4, the first stop structure 4 is used to restrict the external conductive element and / or clamping elastic element 3 from leaving the assembly space 101, the first fixed end 401 of the first stop structure 4 is connected to the conductive clamping wall 201, the first free end 402 of the first stop structure 4 extends in the direction of the clamping elastic element 3, and the first stop structure 4 is configured as a strip structure.

[0131] By adopting the above technical solution,

[0132] In use, the user can operate the clamping elastic member 3 so that the elastic clamping section 301 of the clamping elastic member 3 moves away from the conductive clamping wall 201. At this time, an external conductive member, such as a cable, can be inserted between the conductive clamping wall 201 and the elastic clamping section 301 through the insertion channel 102. When the external force applied to the clamping elastic member 3 is removed, the clamping elastic member 3, under its elastic action, resets the elastic clamping section 301 towards the conductive clamping wall 201 to clamp the external conductive member between the conductive clamping wall 201 and the elastic clamping section 301.

[0133] Due to the provision of the first stop structure 4, the first stop structure 4 can limit and stop the external conductive component inserted between the conductive clamping wall 201 and the elastic clamping section 301, preventing the external conductive component from being inserted out of the assembly opening 103; and / or the first stop structure 4 can limit and stop the clamping elastic component 3, preventing the clamping elastic component 3 from being dislodged from the assembly opening 103, ensuring the reliability and stability of the wiring terminal;

[0134] In the above structure, the first stop structure 4 is configured as a strip structure, which can reduce the use of metal materials and greatly reduce production costs compared with the sheet metal structure in the prior art.

[0135] Specifically, the insulating substrate 1 has an assembly opening 103 on one side perpendicular to the axis of the insertion channel 102, which communicates with the assembly space 101. During production and installation, the current-carrying component 2 and the clamping elastic component 3 are installed into the assembly space 101 through the assembly opening 103. The first stop structure 4 is disposed on the side of the assembly opening 103, and the first stop structure 4 is used to restrict the external conductive component and / or the clamping elastic component 3 from leaving the assembly space 101 through the assembly opening 103.

[0136] Furthermore, the current-carrying component 2 includes a current-carrying substrate 202, and one end of the conductive clamping wall 201 and one end of the current-carrying substrate 202 are connected by a bending structure 204.

[0137] By adopting the above technical solution, the current-carrying component 2 is made more reasonable. Specifically, the conductive clamping wall 201 is arranged perpendicularly to the current-carrying substrate 202. Specifically, the current-carrying substrate 202 and the conductive clamping wall 201 are integrally formed.

[0138] Furthermore, the first free end 402 of the first stop structure 4 is disposed at least across the communication port 102-2 on the side facing the conductive clamping wall 201.

[0139] By adopting the above technical solution, the structure of the first stop structure 4 is made more reasonable, so that it can play a better role in limiting and stopping.

[0140] In some embodiments, the first free end 402 of the first stop structure 4 is disposed across both sides of the connecting port 102-2, and the above structure enables the first stop structure 4 to play a better limiting and stopping role.

[0141] In some embodiments, the first free end 402 of the first stop structure 4 is provided only across the communication port 102-2 on the side facing the conductive clamping wall 201. The above structure makes the length of the first stop structure 4 relatively short. When the clamping elastic member 3 is installed, the clamping elastic member 3 can be installed in a way that deforms at a small angle, avoiding large angle deformation that weakens its elasticity and ensuring the reliability of the clamping elastic member 3.

[0142] Furthermore, in some embodiments, the terminal block includes a second stop structure 5, the second fixed end 501 of the second stop structure 5 being connected to the current-carrying substrate 202, and the second free end 502 extending in the direction of the communication port 102-2, and the second stop structure 5 being configured as a strip structure.

[0143] The above technical solution makes the wiring terminal more reasonable. The first stop structure 4 and the second stop structure 5 can cooperate to play a limiting and stopping role. In particular, for the limiting and stopping of the clamping elastic member 3, when the elastic member clamping section 301 moves away from the conductive clamping wall 201, it can be limited and stopped by the first stop structure 4 at the beginning and by the second stop structure 5 at the end.

[0144] The second stop structure 5 can compensate for the relatively short length of the first stop structure 4, thus ensuring reliability;

[0145] In the above structure, the second stop structure 5 is configured as a strip structure, which can reduce material usage and greatly reduce production costs; specifically, the second stop structure 5 is disposed on the side of the assembly opening 103.

[0146] Furthermore, the first stop structure 4 is made of a rigid material.

[0147] By adopting the above technical solution, the first stop structure 4 becomes more reasonable and reliable. The insertion of the external conductive component will apply force to the first stop structure 4. When the external conductive component tends to come out during the clamping process, it will also apply force to the first stop structure 4. When the clamping elastic component 3 tends to come out due to its own deformation, it will also apply force to the first stop structure 4. The above structure enables the first stop structure 4 to withstand higher external forces and to maintain its shape or prevent it from being damaged, thus ensuring the limiting and stopping effect of the first stop structure 4.

[0148] Furthermore, the extension direction of the first free end 402 of the first stop structure 4 is perpendicular to the central axis of the communication port 102-2.

[0149] By adopting the above technical solution, the first stop structure 4 becomes more reasonable.

[0150] Furthermore, the first stop structure 4 includes a first stop free arm 403 and a first stop connecting arm 404. One end of the first stop connecting arm 404 is formed as the first fixed end 401, and the other end is connected to one end of the first stop free arm 403. The other end of the first stop free arm 403 is formed as the first free end 402. The first stop connecting arm 404 is bent so that the first stop free arm 403 extends in the direction of the clamping elastic member 3.

[0151] By adopting the above technical solution, the first stop structure 4 becomes more reasonable and easier to manufacture.

[0152] Furthermore, the first stop structure 4 is formed by bending a portion of the conductive clamping wall 201.

[0153] By adopting the above technical solution, the first stop structure 4 and the conductive clamping wall 201 are more reasonable, which not only facilitates actual production, but also ensures that the connection between the first stop structure 4 and the conductive clamping wall 201 is more stable and reliable.

[0154] Since the conductive clamping wall 201 is made of conductive metal material, the rigidity of the first stop structure 4 can be guaranteed.

[0155] Furthermore, the second stop structure 5 is made of a rigid material.

[0156] By adopting the above technical solution, the second stop structure 5 becomes more reasonable and reliable. The insertion of the external conductive component will apply force to the second stop structure 5. When the external conductive component tends to come out during the clamping process, it will also apply force to the second stop structure 5. When the clamping elastic component 3 tends to come out due to its own deformation, it will also apply force to the second stop structure 5. The above structure enables the second stop structure 5 to withstand higher external forces and to maintain its shape or prevent damage, thus ensuring the limiting and stopping effect of the second stop structure 5.

[0157] Furthermore, the second stop structure 5 includes a second stop free arm 503 and a second stop connecting arm 504. One end of the second stop connecting arm 504 is formed as the second fixed end 501, and the other end is connected to one end of the second stop free arm 503. The other end of the second stop free arm 503 is formed as the second free end 502. The second stop connecting arm 504 is bent so that the second stop free arm 503 extends along the direction of the communication port 102-2.

[0158] By adopting the above technical solution, the second stop structure 5 becomes more reasonable and easier to manufacture.

[0159] Furthermore, the second stop structure 5 is formed by bending a portion of the current-carrying substrate 202.

[0160] By adopting the above technical solution, the second stop structure 5 and the current-carrying substrate 202 are more reasonable, which not only facilitates actual production, but also ensures that the connection between the second stop structure 5 and the current-carrying substrate 202 is more stable and reliable.

[0161] Since the current-carrying substrate 202 is made of a conductive metal material, the rigidity of the second stop structure 5 can be guaranteed.

[0162] Furthermore, the current-carrying substrate 202 of the current-carrying component 2 is provided with an abutment portion 203, and the clamping elastic component 3 includes an installation mating section 302 and an intermediate connecting section 303. The intermediate connecting section 303 is disposed between the installation mating section 302 and the elastic component clamping section 301, and the two ends of the intermediate connecting section 303 are respectively connected to one end of the installation mating section 302 and one end of the elastic component clamping section 301. The other end of the installation mating section 302 abuts against the side of the abutment portion 203 facing the conductive clamping wall 201.

[0163] By adopting the above technical solution, the clamping elastic element 3 and the current-carrying substrate 202 are more reasonable. The abutment part 203 and the mounting mating section 302 can not only realize the positioning of the clamping elastic element 3 on the current-carrying fluid 2, but also the abutment part 203 can provide support for the mounting mating section 302 of the clamping elastic element 3.

[0164] Furthermore, a portion of the current-carrying substrate 202 is bent to form the abutment portion 203.

[0165] By adopting the above technical solution, the abutment part 203 is made more reasonable, which not only facilitates actual production, but also facilitates the abutment part 203 to abut against the mounting end of the clamping elastic member 3.

[0166] Furthermore, the abutment portion 203 is located between the first stop structure 4 and the inner wall of the assembly space 101 opposite to the first stop structure 4.

[0167] By adopting the above technical solution, the arrangement of the abutment part 203 is more reasonable; specifically, the abutment part 203 is bent at 90 degrees relative to the current-carrying substrate 202.

[0168] The abutment 203 is located on the longitudinal centerline of the fluid carrier 2, and the first stop structure 4 is located on one side of the longitudinal centerline of the fluid carrier 2; when the second stop structure 5 is provided, the second stop structure 5 is located on one side of the longitudinal centerline of the fluid carrier 2, and the second stop structure 5 and the first stop structure 4 are located on the same side of the longitudinal centerline of the fluid carrier 2.

[0169] Furthermore, the intermediate connecting section 303 of the clamping elastic member 3 has an arc-shaped structure.

[0170] The above technical solution makes the intermediate connecting segment 303 more reasonable.

[0171] Furthermore, the terminal block also includes an elastic support 10, and an elastic intermediate slot 11 matching the intermediate connecting section 303 is formed between the elastic support 10 and the inner wall of the assembly space 101, and the intermediate connecting section 303 is inserted into the elastic intermediate slot 11.

[0172] By adopting the above technical solution, the insulating substrate 1 is made more reasonable, and the middle slot 11 of the elastic element facilitates the positioning and installation of the clamping elastic element 3, ensuring its stable and reliable operation.

[0173] Specifically, the side of the assembly space 101 opposite to the assembly opening 103 is referred to as the assembly opening opposite side 104, and the assembly opening opposite side 104 protrudes towards the assembly opening 103 to form the elastic support platform 10.

[0174] Furthermore, the terminal block also includes an elastic element limiting boss 13, which is spaced apart from the conductive clamping wall 201 on the side facing the conductive clamping wall 201, and the elastic element limiting boss 13 is located on the movement trajectory of the elastic element clamping section 301.

[0175] By adopting the above technical solution, the insulating substrate 1 is made more reasonable, and the setting of the elastic element limiting boss 13 can limit the maximum movement of the elastic element clamping section 301, avoid the excessive deformation of the clamping elastic element 3 leading to a weakening of its elasticity, and ensure the reliability of the clamping elastic element 3.

[0176] Specifically, the assembly opening opposite side 104 protrudes towards the assembly opening 103 to form the elastic element limiting boss 13.

[0177] Furthermore, along the direction from the bottom surface 105 of the assembly space to the communication port 102-2, the elastic element limiting boss 13 gradually tilts away from the conductive clamping wall 201 from the side facing the conductive clamping wall 201.

[0178] By adopting the above technical solution, the elastic element limiting boss 13 is more reasonable, which makes it easier for it to more reliably limit the elastic element clamping section 301.

[0179] Furthermore, the elastic element limiting boss 13 is spaced apart from the bottom surface 105 of the assembly space, and the distance between the elastic element limiting boss 13 and the bottom surface 105 of the assembly space is greater than or equal to the thickness at the corresponding position of the current-carrying substrate 202.

[0180] By adopting the above technical solution, the setting of the elastic element limiting boss 13 is more reasonable, and space is reserved for the installation of the current-carrying substrate 202, that is, the current-carrying substrate 202 can be installed between the elastic element limiting boss 13 and the bottom surface 105 of the assembly space.

[0181] Furthermore, the terminal block includes a button 15 movably disposed on the insulating substrate 1, and the button 15 is capable of driving the elastic clamping section 301 to move away from the conductive clamping wall 201 during operation.

[0182] By adopting the above technical solution, the wiring terminal is more reasonable. The button 15 allows the operator to drive the elastic clamping section 301 to move away from the conductive clamping wall 201 by operating the button 15. The movement of the elastic clamping section 301 by the button 15 is also more stable and reliable.

[0183] Furthermore, the button 15 is disposed on the side of the elastic clamping section 301 facing the insertion port 102-1, and the moving direction of the button 15 relative to the insulating substrate 1 is parallel to the axis of the insertion channel 102.

[0184] By adopting the above technical solution, the button 15 is set more reasonably, so that it can stably and reliably drive the elastic clamping section 301 to move away from the conductive clamping wall 201.

[0185] Furthermore, the insertion channel 102 is provided in multiple ways, and the number of conductive clamping walls 201, clamping elastic members 3, the first stop structure 4 and the abutment part 203 are matched with the number of insertion channels 102 and correspond one-to-one.

[0186] When the second stop structure 5 is provided, the number of the second stop structures 5 is matched with the number of the insertion channels 102 and corresponds one-to-one.

[0187] The above technical solution makes the wiring terminals more reasonable.

[0188] Example 2

[0189] See Figure 4 Example 2 is basically the same as Example 1, except that:

[0190] The second stop structure 5 is not provided in the terminal block, and the side of the assembly space 101 opposite to the communication port 102-2 is called the bottom surface 105 of the assembly space;

[0191] The first stop structure 4 is spaced apart from the side of the surface where the connection port 102-2 is located. The terminal block includes a third stop structure 6 for restricting the external conductive element and / or the clamping elastic element 3 from disengaging from the assembly space 101. The third stop structure 6 is located between the side of the first stop structure 4 facing the surface where the connection port 102-2 is located and the surface where the connection port 102-2 is located.

[0192] By adopting the above technical solution, the third stop structure 6 can limit and stop the external conductive component and / or clamping elastic component 3, preventing the external conductive component and / or clamping elastic component 3 from detaching from the assembly space 101, and ensuring the reliability and stability of the wiring terminal; specifically, the third stop structure 6 is disposed on the assembly opening side 103.

[0193] Furthermore, the side of the third stop structure 6 facing the clamping elastic member 3 is coplanar with the side of the first stop structure 4 facing the clamping elastic member 3.

[0194] By adopting the above technical solution, the third stop structure 6 and the first stop structure 4 are made more reasonable, avoiding the oblique part of the third stop structure 6 and the first stop structure 4 from affecting the insertion of the external conductive component and the movement of the elastic clamping section 301, thus ensuring smooth insertion of the external conductive component and smooth movement of the elastic clamping section 301.

[0195] Furthermore, the third stop structure 6 is configured as a sheet structure, and the third stop structure 6 is made of plastic.

[0196] By adopting the above technical solution, the third stop structure 6 is more reasonable, and the sheet-like structure of the third stop structure 6 can have a better stopping effect; moreover, since the third stop structure 6 is made of plastic, the cost can be greatly reduced compared with metal materials.

[0197] Since the third stop structure 6 is made of plastic, its endurance on the side edge away from the communication port 102-2 is relatively poor. The first stop structure 4 is located on the side of the third stop structure 6 away from the communication port 102-2 to withstand external forces and alleviate the force on the side edge of the third stop structure 6 away from the communication port 102-2. The structure is reasonable and reliable.

[0198] Furthermore, the third stop structure 6 extends toward the conductive clamping wall 201 from the side facing the conductive clamping wall 201 to approach or cross the communication port 102-2 toward the conductive clamping wall 201; the third stop structure 6 extends away from the conductive clamping wall 201 from the side away from the conductive clamping wall 201 to approach or cross the communication port 102-2 away from the conductive clamping wall 201.

[0199] By adopting the above technical solution, the structure of the third stop structure 6 is made more reasonable, so that it can play a better role in limiting and stopping.

[0200] Furthermore, the third stop structure 6 has a first clamping arm passage 8 between the side facing the conductive clamping wall 201 and the assembly space 101, through which the conductive clamping wall 201 passes.

[0201] By adopting the above technical solution, the third stop structure 6 is more reasonable and facilitates actual production and installation. When installing the current-carrying component 2, the conductive clamping wall 201 can pass through the first clamping arm opening 8 and be installed into the assembly space 101, thus avoiding the setting of the third stop structure 6 from affecting the installation of the current-carrying component 2.

[0202] Furthermore, the side of the third stop structure 6 facing the surface of the connecting port 102-2 is connected to the insulating substrate 1. Specifically, the side of the third stop structure 6 facing the surface of the connecting port 102-2 is connected to the side of the assembly opening 103 near the surface of the connecting port 102-2.

[0203] By adopting the above technical solution, the third stop structure 6 is made more reasonable, so as to realize the connection between the third stop structure 6 and the insulating substrate 1.

[0204] Furthermore, the third stop structure 6 is integrally formed with the insulating substrate 1.

[0205] The above technical solution not only facilitates actual production, but also ensures the reliability of the connection of the third stop structure 6; and both the third stop structure 6 and the insulating substrate 1 are made of plastic, which facilitates the integral molding of the two.

[0206] Furthermore, the number of the third stop structures 6 is matched and corresponds one-to-one with the number of the insertion channels 102.

[0207] The above technical solution makes the wiring terminals more reasonable.

[0208] Example 3

[0209] See Figure 5Example 3 is basically the same as Example 1, except that:

[0210] The second stop structure 5 is not provided in the terminal block, and the side of the assembly space 101 opposite to the communication port 102-2 is called the bottom surface 105 of the assembly space;

[0211] The first stop structure 4 is spaced apart from the side of the assembly space bottom surface 105. The terminal block includes a fourth stop structure 7 for restricting the external conductive element and / or clamping elastic element 3 from disengaging from the assembly space 101. The fourth stop structure 7 is disposed on the side of the assembly opening 103 and is located between the side of the first stop structure 4 facing the assembly space bottom surface 105 and the assembly space bottom surface 105.

[0212] By adopting the above technical solution, the fourth stop structure 7 can limit and stop the external conductive component and / or clamping elastic component 3, preventing the external conductive component and / or clamping elastic component 3 from detaching from the assembly space 101, and ensuring the reliability and stability of the wiring terminal; specifically, the fourth stop structure 7 is disposed on the assembly opening side 103.

[0213] Furthermore, the side of the fourth stop structure 7 facing the clamping elastic member 3 is coplanar with the side of the first stop structure 4 facing the clamping elastic member 3.

[0214] By adopting the above technical solution, the fourth stop structure 7 and the first stop structure 4 are made more reasonable, avoiding the oblique part of the fourth stop structure 7 and the first stop structure 4 from affecting the insertion of the external conductive component and the movement of the elastic clamping section 301, thus ensuring smooth insertion of the external conductive component and smooth movement of the elastic clamping section 301.

[0215] Furthermore, the fourth stop structure 7 is configured as a sheet structure, and the fourth stop structure 7 is made of plastic.

[0216] By adopting the above technical solution, the fourth stop structure 7 is more reasonable, and the sheet-like structure of the fourth stop structure 7 can have a better stopping effect; moreover, since the fourth stop structure 7 is made of plastic, the cost can be greatly reduced compared with metal materials.

[0217] Since the fourth stop structure 7 is made of plastic, its endurance on the side edge facing the communication port 102-2 is relatively poor. The first stop structure 4 is located on the side of the fourth stop structure 7 facing the communication port 102-2 to withstand external forces and alleviate the force on the side edge of the fourth stop structure 7 facing the communication port 102-2. The structure is reasonable and reliable.

[0218] Furthermore, the fourth stop structure 7 extends toward the conductive clamping wall 201 on the side facing the conductive clamping wall 201 to approach or cross the communication port 102-2 on the side facing the conductive clamping wall 201; the fourth stop structure 7 extends away from the conductive clamping wall 201 on the side away from the conductive clamping wall 201 to approach or cross the communication port 102-2 on the side away from the conductive clamping wall 201.

[0219] By adopting the above technical solution, the structure of the fourth stop structure 7 is made more reasonable, so that it can play a better role in limiting and stopping.

[0220] Furthermore, the fourth stop structure 7 is provided with a second clamping arm passage 9 between the side facing the conductive clamping wall 201 and the assembly space 101, through which the conductive clamping wall 201 passes.

[0221] By adopting the above technical solution, the fourth stop structure 7 is more reasonable and facilitates actual production and installation. When installing the current-carrying component 2, the conductive clamping wall 201 can pass through the second clamping arm opening 9 and be installed into the assembly space 101, thus avoiding the setting of the fourth stop structure 7 from affecting the installation of the current-carrying component 2.

[0222] Furthermore, the fourth stop structure 7 is connected to the insulating substrate 1 on the side facing the bottom surface 105 of the assembly space. Specifically, the side of the fourth stop structure 7 facing the bottom surface 105 of the assembly space is connected to the side of the assembly opening 103 near the bottom surface 105 of the assembly space; or the insulating body 1 is provided with a stop structure connecting part 12 at the fourth stop structure 7, and the fourth stop structure 7 is connected to the stop structure connecting part 12.

[0223] By adopting the above technical solution, the fourth stop structure 7 is made more reasonable, so as to realize the connection between the fourth stop structure 7 and the insulating substrate 1;

[0224] Specifically, the assembly opening opposite side 104 protrudes towards the assembly opening 103 to form a stop structure connection part 12.

[0225] Furthermore, the fourth stop structure 7 is integrally formed with the insulating substrate 1.

[0226] The above technical solution not only facilitates actual production, but also ensures the reliability of the connection of the fourth stop structure 7; and both the fourth stop structure 7 and the insulating substrate 1 are made of plastic, which facilitates the integral molding of the two.

[0227] Furthermore, when the fourth stop structure 7 is connected to the insulating substrate 1 through the stop structure connecting part 12, the stop structure connecting part 12 is disposed on the side of the fourth stop structure 7 away from the conductive clamping wall 201, or the stop structure connecting part 12 is disposed on the side of the fourth stop structure 7 facing the bottom surface 105 of the assembly space.

[0228] By adopting the above technical solution, the stop structure connection part 12 is made more reasonable, avoiding its impact on the insertion of external conductive parts and the movement of the elastic clamping section 301.

[0229] Furthermore, when the fourth stop structure 7 is connected to the insulating substrate 1 through the stop structure connecting part 12 and the stop structure connecting part 12 is located on the side of the fourth stop structure 7 away from the conductive clamping wall 201, an elastic element mounting port 14 is provided between the side of the fourth stop structure 7 facing the surface of the communication port 102-2 and the stop structure connecting part 12.

[0230] By adopting the above technical solution, the setting of the elastic element mounting port 14 facilitates the installation of the elastic element clamping segment 301 into the assembly space 101 through the elastic element mounting port 14 when the clamping elastic element 3 is installed.

[0231] Furthermore, the fourth stop structure 7 is spaced apart from the bottom surface 105 of the assembly space, and the distance between the fourth stop structure 7 and the bottom surface 105 of the assembly space is greater than or equal to the thickness at the corresponding position of the current-carrying substrate 202. The fourth stop structure 7 is connected to the insulating substrate 1 through the stop structure connecting part 12.

[0232] By adopting the above technical solution, the fourth stop structure 7 is set more reasonably, and space is reserved for the installation of the current-carrying substrate 202, that is, the current-carrying substrate 202 can be installed between the fourth stop structure 7 and the bottom surface 105 of the assembly space.

[0233] Furthermore, the elastic element limiting boss 13 is disposed on the side of the fourth stop structure 7 away from the conductive clamping wall 201, and the elastic element limiting boss 13 is formed as the stop structure connecting part 12.

[0234] By adopting the above technical solution, the structure of the terminal block is more reasonable, and the elastic element limiting boss 13 is formed as the stop structure connection part 12, which simplifies the overall structure; and since the elastic element limiting boss 13 gradually tilts away from the conductive clamping wall 201 from the side facing the conductive clamping wall 201, it is convenient to form the elastic element mounting port 14.

[0235] Furthermore, the number of fourth stop structures 7 is matched and corresponds one-to-one with the number of insertion channels 102.
