Technical Field

[0001] The present application relates to the technical field of low-voltage electrical appliances, and in particular to a wiring terminal and a contactor. Background Art

[0002] A contactor is a device that can quickly cut off the AC and DC main circuits and can frequently connect and disconnect high-current control circuits. It can be used as an important electrical device to control the start and stop of motors, so the reliability of the wiring is more important.

[0003] The wiring terminals provided in the contactor are used to connect with external wires. Existing wiring terminals are widely used in the form of wiring frames, in which a wire pressing structure is provided. The static contact plate used for conduction in the contactor extends into the wiring frame, and the wire pressing structure can crimp the external wires onto the static contact plate.

[0004] However, the existing wire crimping structure is inconvenient to perform wiring operations when wiring the wiring terminals, resulting in low wiring efficiency. Utility Model Content

[0005] The purpose of the present application is to provide a wiring terminal and a contactor, which can simplify wiring operations to improve wiring stability and wiring efficiency.

The wiring frame is movably installed in the housing cavity, and the static contact plate is partially located in the wiring frame. The wire pressing frame is movably installed in the housing cavity, and an adjusting member is rotatably connected to the wire pressing frame, and the adjusting member partially passes through the wire pressing frame and is connected to the wiring frame. The static contact plate separates the wiring frame into a first wiring cavity and a second wiring cavity, and the wire pressing frame is buckled in the first wiring cavity. The adjusting member can drive the wire pressing frame to move relative to the wiring frame to compress or expand the first wiring cavity and / or the second wiring cavity.

[0007] Based on the above-mentioned embodiments of the present application, the internal space of the wiring frame is divided into a first adjacent wiring cavity and a second adjacent wiring cavity by extending the static contact plate into the wiring frame, so that the same wiring frame has two adjacent wiring spaces, which facilitates wiring operations on the wiring terminals, improves wiring efficiency, and expands the scope of application of the wiring terminals.

[0009] Based on the above-mentioned embodiments of the present application, the adjusting member is set as a screw to facilitate the adjustment operation.

By setting a limiting structure on the screw, on the one hand, the screw can be restricted on the wire pressing frame, thereby improving the connection stability between the screw and the wire pressing frame and preventing the screw from accidentally slipping or falling off during rotation. On the other hand, when adjusting the screw, the wire pressing frame can be driven to move by the screw to adjust the position of the wire pressing frame. At the same time, the threaded hole provided on the wiring frame is threadedly connected to the screw on the wire pressing frame, so that the position of the wire pressing frame relative to the wiring frame can be adjusted by rotating the screw to adjust the matching length of the screw and the threaded hole.

When the wire pressing frame is buckled on the wiring frame, the first frame wall is between the third frame wall and the fourth frame wall, and the fourth frame wall is between the first frame wall and the second frame wall. By adopting such a similar interlocking connection form, the wire pressing frame and the wiring frame can move relative to each other, and the wire pressing frame and the wiring frame will not easily detach, and the overall structural stability of the wiring terminal is relatively high.

[0016] In an optional embodiment, an elastic member is provided between the second frame wall and the inner wall of the accommodating cavity, the first end of the elastic member abuts against the side of the second frame wall away from the first frame wall, and the second end of the elastic member abuts against the inner wall of the accommodating cavity. The elastic member can drive the second frame wall to abut against the static contact plate.

[0017] Based on the above-mentioned embodiments of the present application, the setting of the elastic member can apply an elastic pre-tightening force to the second frame wall, so that the second frame wall has a movement tendency toward the direction where the static contact plate is located, so that the second frame wall can apply a pre-tightening force to the wire connected to the second wiring cavity, so that the wire can be subsequently fastened in the second wiring cavity by adjusting the screw, which facilitates the wiring operation and effectively improves the wiring efficiency.

[0018] In an optional embodiment, a first baffle is provided on the wiring frame, the first baffle is connected to the second frame wall and extends toward a side of the second frame wall away from the first frame wall, and the first baffle is located on one side of the elastic member.

[0019] Based on the above-mentioned embodiments of the present application, the first baffle can be used to limit the position of the elastic member, prevent the elastic member from being separated from the wiring frame and the inner wall of the accommodating cavity, and enable the elastic member to stably act on the wiring frame. At the same time, the first baffle can also protect the elastic member, reduce the risk of damage to the elastic member, and increase the service life of the elastic member.

[0020] In an optional embodiment, a clamping boss is provided on the second frame wall, and a clamping groove is provided on the first baffle plate, and the clamping groove and the clamping boss are clamped with each other.

[0021] Based on the above-mentioned embodiments of the present application, the first baffle plate can be stably connected to the second frame wall under the clamping cooperation of the clamping boss and the clamping groove, preventing the first baffle plate from easily detaching from the second frame wall, thereby improving assembly stability. In addition, the clamping boss and the clamping groove have a simple structure, are easy to manufacture, and have a simple matching method, which is convenient for assembly operation.

[0022] In the second aspect, an embodiment of the present application also provides a contactor, including a shell and the above-mentioned terminal, the shell having a accommodating cavity, a static contact plate being arranged in the accommodating cavity, the terminal being installed in the accommodating cavity, the static contact plate being partially located in a wiring frame of the terminal, the static contact plate separating the wiring frame into a first wiring cavity and a second wiring cavity, a first wiring hole and a second wiring hole being arranged on the shell, the first wiring hole being connected to the first wiring cavity, and the second wiring hole being connected to the second wiring cavity.

[0023] Based on the above-mentioned embodiments of the present application, the contactor with the above-mentioned wiring terminals can effectively improve the wiring efficiency and wiring stability, which is beneficial to improve the accuracy and reliability of the contactor's control over the main circuit, reduce the risk of contactor failure, and improve the safety of use of the contactor and the main circuit.

[0025] Based on the above-mentioned embodiments of the present application, since the length of the first baffle matches the length of the elastic member when in a normal state, the setting of the avoidance hole can be used to avoid the first baffle, so that in the process of the wiring frame compressing the elastic member, the first baffle can move with the second frame wall and pass through the shell, avoiding the first baffle from abutting against the bottom wall of the shell to affect the movement of the wiring frame, thereby avoiding affecting the expansion of the second wiring cavity.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0043] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0044] In the description of this application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] As a switching device, the contactor can realize the on and off of the main circuit through the control circuit. In order to achieve accurate control of the on and off of the main circuit, the contactor needs to maintain a stable electrical connection with the main circuit. In the contactor, the wiring terminal is usually connected to the wire of the main circuit to connect the contactor to the main circuit, so that the contactor can control the on and off of the main circuit.

[0046] The wiring terminals in existing contactors are widely in the form of wiring frames, and the wires of the main circuit can be extended into the wiring frames. The wires are crimped onto the static contact plate of the contactor through the wire crimping structure set in the wiring frame to achieve the wiring of the wiring terminals. However, this setting form makes it possible to wire the wiring terminals only in the space between the wire crimping structure and the static contact plate. When wiring is to be connected to the side of the static contact plate away from the wire crimping structure, other tools are needed to adjust the position of the wiring frame, which is more complicated to operate and has a smaller operating space for wiring. When multiple wires need to be connected, the wiring efficiency is low.

[0047] Based on this, the embodiments of the present application provide a wiring terminal and a contactor, which can simplify wiring operations to improve wiring stability and wiring efficiency.

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0049] Please refer to Figures 1 to 4 , this embodiment provides a wiring terminal 200, which is arranged in the accommodating cavity of the housing 101, and a static contact plate 102 is arranged in the accommodating cavity. The wiring terminal 200 includes a wiring frame 1 and a wire pressing frame 2. The wiring frame 1 is movably installed in the accommodating cavity, and the static contact plate 102 is partially located in the wiring frame 1. The wire pressing frame 2 is movably installed in the accommodating cavity, and an adjusting member is rotatably connected to the wire pressing frame 2, and the adjusting member partially passes through the wire pressing frame 2 and is connected to the wiring frame 1. The static contact plate 102 separates the wiring frame 1 into a first wiring cavity 11 and a second wiring cavity 12, and the wire pressing frame 2 is buckled in the first wiring cavity 11. The adjusting member can drive the wire pressing frame 2 to move relative to the wiring frame 1 to compress or expand the first wiring cavity 11 and / or the second wiring cavity 12.

[0050] Reference Figure 1 The terminal block 200 provided in the present application can be applied to the contactor 100, and can also be applied to switch devices such as circuit breakers or relays, which can improve the wiring efficiency and wiring stability of the corresponding equipment. The above-mentioned switch devices all have a housing 101, and the terminal block 200 is installed in the accommodating cavity of the housing 101. It can play a certain protective role on the terminal block 200 without affecting the wiring of the terminal block 200, and can also reduce the risk of electric shock. The static contact plate 102 is fixedly arranged in the accommodating cavity, and the static contact plate 102 is used to achieve contact and conduction with the wire connected to the terminal block 200 to ensure stable electrical connection with the main circuit.

[0051] Among them, refer to Figure 3 and Figure 4 , the wiring frame 1 can move in the accommodating cavity, while the static contact plate 102 is fixedly arranged in the accommodating cavity. With the aforementioned movement process, the space size of the first wiring cavity 11 and the second wiring cavity 12 can change accordingly. Specifically, the relative position between the wiring frame 1 and the static contact plate 102 changes during the movement, so that the space size of the first wiring cavity 11 and the second wiring cavity 12 in the wiring frame 1 changes. In this way, when the wiring frame 1 moves relative to the static contact plate 102 in the direction of the first wiring cavity 11, the space of the first wiring cavity 11 becomes larger, and the space of the second wiring cavity 12 becomes smaller. When the wiring frame 1 moves relative to the static contact plate 102 in the direction of the second wiring cavity 12, the space of the second wiring cavity 12 becomes larger, and the space of the first wiring cavity 11 becomes smaller.

[0052] The first wiring chamber 11 and the second wiring chamber 12 can meet different wiring requirements. For example, the wire close to the first wiring chamber 11 can be selected to be wired in the first wiring chamber 11. Correspondingly, the wire close to the second wiring chamber 12 can be selected to be wired in the second wiring chamber 12. When wiring is required in the first wiring chamber 11, the wiring frame 1 can be moved relative to the static contact plate 102 in the direction of the first wiring chamber 11 to expand the first wiring chamber 11. The space of the expanded first wiring chamber 11 becomes larger, thereby facilitating wiring operations. Similarly, when wiring is required in the second wiring chamber 12, the wiring frame 1 can be moved relative to the static contact plate 102 in the direction of the second wiring chamber 12 to expand the second wiring chamber 12. The space of the expanded second wiring chamber 12 becomes larger, thereby facilitating wiring operations and helping to improve wiring efficiency. This design also enables the terminal block 200 to adapt to wires of different sizes and specifications, providing greater flexibility and applicability.

[0053] The wire pressing frame 2 can also move in the accommodating cavity. The movement of the wire pressing frame 2 can be achieved by operating the adjusting member. For example, the relative movement between the operating adjusting member and the wiring frame 1 can drive the relative movement between the wire pressing frame 2 and the wiring frame 1.

[0054] Based on the above-mentioned embodiments of the present application, the static contact plate 102 is extended into the wiring frame 1 to divide the internal space of the wiring frame 1 into adjacent first wiring chamber 11 and second wiring chamber 12, so that the same wiring frame 1 has two adjacent wiring spaces, which facilitates wiring operations on the wiring terminal 200, improves wiring efficiency, and expands the scope of application of the wiring terminal 200.

[0055] Reference Figures 3 to 5 In some examples, the adjusting member is configured as a screw 3, which is rotatably connected to a side of the wire pressing frame 2 away from the wiring frame 1, and a limiting structure 31 is provided at the rotational connection. A threaded hole 13 is provided on the wiring frame 1, and the screw 3 is threadedly connected to the threaded hole 13.

[0056] Based on the above-mentioned embodiments of the present application, the adjusting member is set as a screw 3 to facilitate the adjustment operation. The structure of the screw 3 is simple, easy to assemble and low in cost. By setting a limiting structure 31 on the screw 3, on the one hand, the screw 3 can be limited to the wire pressing frame 2, the connection stability between the screw 3 and the wire pressing frame 2 is improved, and the screw 3 is prevented from accidentally slipping or falling off during the rotation process. On the other hand, when adjusting the screw 3, the wire pressing frame 2 can be driven to move by the screw 3 to adjust the position of the wire pressing frame 2. At the same time, the threaded hole 13 set on the wiring frame 1 is threadedly connected with the screw 3 on the wire pressing frame 2, so that the position of the wire pressing frame 2 relative to the wiring frame 1 can be adjusted by rotating the screw 3 to adjust the matching length of the screw 3 and the threaded hole 13. This connection method can simplify the adjustment operation, effectively reduce the difficulty of the adjustment operation, and improve the wiring efficiency.

[0057] Reference Figures 2 to 4 In some examples, the screw 3 includes a nut 32 and a screw rod 33, the nut 32 is located on the side of the wire pressing frame 2 away from the wiring frame 1, the limiting structure 31 is arranged on the screw rod 33, the screw rod 33 partially passes through the wire pressing frame 2, and an external thread is arranged on the screw rod 33 and is threadedly connected to the threaded hole 13.

[0058] Based on the above-mentioned embodiments of the present application, the nut 32 is arranged on the side of the wire pressing frame 2 away from the wiring frame 1, and the screw rod 33 partially passes through the wire pressing frame 2 and is connected to the wiring frame 1, so that the screw 3 is always on the wire pressing frame 2, and the nut 32 used for operation is in an easy-to-adjust position, which is convenient for timely adjustment of the wire pressing frame 2 and the wiring frame 1, thereby improving the convenience of wiring operation and reducing the risk of unstable wiring of the terminal 200.

[0059] Among them, refer to Figure 3 and Figure 4 The nut 32 is arranged on the side of the wire pressing frame 2 away from the wiring frame 1. The user can directly operate the nut 32 to realize the adjustment function. Compared with the existing form in which the screw 3 can be moved as a whole relative to the wire pressing frame 2, this embodiment has the advantage of being able to be adjusted in time, avoiding the problem that the screw 3 needs to be tightened when the wiring is unstable but is difficult to adjust, thereby making the wiring of the terminal 200 more reliable.

[0060] Reference Figure 6 The limiting structure 31 is arranged on the screw 33, and the screw 33 is passed through the wire pressing frame 2. The limiting structure 31 can limit the movement of the screw 3 relative to the wire pressing frame 2 in the adjustment direction of the screw 3, so that the screw 3 can drive the wire pressing frame 2 to move synchronously. When wiring the terminal 200, it is only necessary to adjust the screw 3 to achieve stable wiring.

[0061] Reference Figure 6 The external thread on the screw rod 33 is connected with the threaded hole 13 on the wiring frame 1. Turning the screw 3 actually adjusts the length of the screw 3 and the threaded hole 13. Tightening the screw 3 brings the wire pressing frame 2 and the wiring frame 1 closer together, and loosening the screw 3 moves the wire pressing frame 2 and the wiring frame 1 away from each other. In this way, the relative position of the wire pressing frame 2 and the wiring frame 1 can be quickly adjusted, and the structure is simple and the operation is easy.

[0062] Reference Figure 5 and Figure 6 In some examples, the limiting structure 31 is a limiting groove provided on the screw rod 33, in which a spring washer 4 is provided, and the spring washer 4 is located on the side of the wire pressing frame 2 away from the wiring frame 1. One side of the spring washer 4 abuts against the nut 32, and the other side abuts against the wire pressing frame 2.

[0063] Based on the above-mentioned embodiment of the present application, the screw 33 is penetrated on the wiring frame 1, and the opening of the limit groove can limit the position of the screw 3 relative to the wire pressing frame 2, so that the relative position of the screw 3 and the wire pressing frame 2 is fixed, so that the nut 32 is always on the side of the wire pressing frame 2 away from the wiring frame 1, so as to facilitate timely adjustment of the screw 3. In addition, the setting of the spring washer 4 can prevent the screw 3 from loosening, avoid the wiring terminal 200 from loosening after being vibrated and causing unstable wiring, and improve the wiring stability of the wiring terminal 200.

[0064] Specifically, refer to Figure 5 and Figure 6 The limiting groove is provided on the screw rod 33 near the nut 32, and the wire pressing frame 2 is provided with a mounting hole 21. After the screw 3 is installed in the mounting hole 21 of the wire pressing frame 2, the wall surface where the mounting hole 21 is located is in the limiting groove, thereby limiting the relative position of the screw 3 and the wire pressing frame 2. The spring washer 4 is sleeved on the screw rod 33 and is in the limiting groove, and the spring washer 4 is located between the nut 32 and the wire pressing frame 2. Such a setting can improve the assembly stability of the screw 3 on the wire pressing frame 2 under the cooperation of the spring washer 4 and the limiting groove.

[0065] Reference Figures 2 to 6 In some examples, the wiring frame 1 includes a first frame wall 14 and a second frame wall 15 that are oppositely disposed, and the wire pressing frame 2 includes a third frame wall 22 and a fourth frame wall 23 that are oppositely disposed, the first frame wall 14 is between the third frame wall 22 and the fourth frame wall 23, and the fourth frame wall 23 is between the first frame wall 14 and the second frame wall 15. The screw 3 is rotatably connected to the third frame wall 22, the threaded hole 13 is disposed on the first frame wall 14, and the screw 3 extends from the third frame wall 22 to the first frame wall 14 and is threadedly connected to the threaded hole 13.

[0066] Based on the above-mentioned embodiments of the present application, the wiring frame 1 formed by the first frame wall 14 and the second frame wall 15 forms an annular structure, and the wire pressing frame 2 formed by the third frame wall 22 and the fourth frame wall 23 forms a similar annular structure. When the wire pressing frame 2 is buckled on the wiring frame 1, the first frame wall 14 is between the third frame wall 22 and the fourth frame wall 23, and the fourth frame wall 23 is between the first frame wall 14 and the second frame wall 15. By adopting such a similar interlocking connection form, the wire pressing frame 2 and the wiring frame 1 can move relative to each other, and the wire pressing frame 2 and the wiring frame 1 will not easily detach, and the overall structural stability of the terminal block 200 is relatively high.

[0067] Specifically, refer to Figure 3 and Figure 4The wire pressing frame 2 is buckled in the first wiring cavity 11 of the wiring frame 1, and the screw 3 connects the third frame wall 22 and the first frame wall 14 at the same time. The adjusting screw 3 can directly adjust the distance between the third frame wall 22 and the first frame wall 14, and the distance between the fourth frame wall 23 and the second frame wall 15. For example, when the screw 3 is tightened, the third frame wall 22 and the first frame wall 14 are close to each other, and the fourth frame wall 23 and the second frame wall 15 are close to each other. When the screw 3 is loosened, the third frame wall 22 and the first frame wall 14 are far away from each other, and the fourth frame wall 23 and the second frame wall 15 are far away from each other.

[0068] Reference Figure 7 and Figure 8 In some examples, an elastic member 5 is disposed between the second frame wall 15 and the inner wall of the accommodating cavity, a first end of the elastic member 5 abuts against a side of the second frame wall 15 away from the first frame wall 14, and a second end of the elastic member 5 abuts against the inner wall of the accommodating cavity. The elastic member 5 can drive the second frame wall 15 to abut against the static contact plate 102.

[0069] Based on the above-mentioned embodiments of the present application, the setting of the elastic member 5 can apply an elastic pre-tightening force to the second frame wall 15, so that the second frame wall 15 has a movement tendency toward the direction of the static contact plate 102, so that the second frame wall 15 can apply a pre-tightening force to the wire connected to the second wiring cavity 12, so that the wire can be subsequently fastened in the second wiring cavity 12 by adjusting the screw 3, which facilitates the wiring operation and effectively improves the wiring efficiency.

[0070] Specifically, refer to Figure 8 The elastic member 5 is configured as a spring, which is disposed on the side of the second frame wall 15 away from the first frame wall 14, that is, between the wiring frame 1 and the bottom wall of the accommodating chamber. The first end of the spring abuts against the side of the second frame wall 15 away from the first frame wall 14, and the second end abuts against the bottom wall of the accommodating chamber. In this way, the second frame can be subjected to the elastic preload force applied by the spring, so that the second frame wall 15 approaches the static contact plate 102, thereby clamping the wire in the second wiring chamber 12 to prevent the wire from escaping from the second wiring chamber 12. When wiring, the wire can be first inserted into the second wiring chamber 12, and the wire can be pre-positioned in the second wiring chamber 12 by the elastic preload force, and then the screw 3 can be tightened to fasten the wire in the second wiring chamber 12, effectively improving the convenience of wiring operation.

[0071] Reference Figure 2 and Figure 5 In some examples, a first baffle 16 is provided on the wiring frame 1 , and the first baffle 16 is connected to the second frame wall 15 and extends to a side of the second frame wall 15 away from the first frame wall 14 , and the first baffle 16 is located on one side of the elastic member 5 .

[0072] Based on the above-mentioned embodiments of the present application, the first baffle 16 can be used to limit the position of the elastic member 5, prevent the elastic member 5 from being separated from between the wiring frame 1 and the inner wall of the accommodating cavity, and enable the elastic member 5 to stably act on the wiring frame 1. At the same time, the first baffle 16 can also protect the elastic member 5, reduce the risk of damage to the elastic member 5, and increase the service life of the elastic member 5.

[0073] Among them, the first baffle 16 is connected to the side of the second frame wall 15, so that the first baffle 16 can move synchronously with the second frame wall 15, and the first baffle 16 extends to the side away from the first frame wall 14, which can block the surrounding side of the elastic member 5 located at the position of the second frame wall 15 away from the first frame wall 14, so as to prevent the elastic member 5 from detaching and protect the elastic member 5 from damage.

[0074] In an optional embodiment, the first baffle 16 includes a protection plate and a positioning plate, and the protection plate extends along the length direction of the elastic member 5 to protect the elastic member 5 from the peripheral side of the elastic member 5. The positioning plate is perpendicular to the protection plate and fixedly connected to the side of the second frame wall 15 facing the elastic member 5. The positioning plate may be provided with a positioning structure, and the elastic member 5 is connected to the positioning structure and abuts against the second frame wall 15 under the action of positioning installation, so that the elastic member 5 can accurately act on the second frame wall 15.

[0075] Reference Figure 5 and Figure 6 In some examples, a clamping boss 151 is provided on the second frame wall 15 , and a clamping groove 161 is provided on the first baffle 16 , and the clamping groove 161 and the clamping boss 151 are clamped with each other.

[0076] Based on the above-mentioned embodiment of the present application, under the clamping cooperation of the clamping boss 151 and the clamping groove 161, the first baffle 16 can be stably connected to the second frame wall 15, preventing the first baffle 16 from easily detaching from the second frame wall 15, thereby improving the assembly stability. In addition, the clamping boss 151 and the clamping groove 161 have a simple structure, are easy to manufacture, and have a simple matching method, which is convenient for assembly operation.

[0077] Specifically, refer to Figure 6 The clamping boss 151 is disposed on the side wall of the second frame wall 15 and extends toward the side wall where the second wiring hole 104 is located. Figure 5 The engaging groove 161 is disposed at the edge of the first baffle 16 . After the engaging groove 161 is engaged with the engaging boss 151 , the first baffle 16 is connected to the second frame wall 15 and is located at the peripheral side of the elastic member 5 .

[0078] In an optional embodiment, the first baffle plate 16 and the second frame wall 15 may also be connected by bonding or welding, which can also achieve a stable connection between the first baffle plate 16 and the second frame wall 15 and has the same technical effect as the aforementioned connection form, which will not be repeated here.

[0079] Reference Figures 9 to 11 The embodiment of the present application also provides a contactor 100, including a shell 101 and the above-mentioned terminal 200, the shell 101 has a accommodating cavity, a static contact plate 102 is arranged in the accommodating cavity, the terminal 200 is installed in the accommodating cavity, the static contact plate 102 is partially located in the wiring frame 1 of the terminal 200, the static contact plate 102 separates the wiring frame 1 into a first wiring cavity 11 and a second wiring cavity 12, the shell 101 is provided with a first wiring hole 103 and a second wiring hole 104, the first wiring hole 103 is connected to the first wiring cavity 11, and the second wiring hole 104 is connected to the second wiring cavity 12.

[0080] Based on the above-mentioned embodiments of the present application, the contactor 100 having the above-mentioned terminal 200 can effectively improve the wiring efficiency and wiring stability, which is beneficial to improving the accuracy and reliability of the contactor 100's control over the main circuit, reducing the risk of failure of the contactor 100, and improving the safety of use of the contactor 100 and the main circuit.

[0081] Among them, refer to Fig.10 and Fig.11 The first wiring hole 103 and the second wiring hole 104 are usually opened on the side wall of the shell 101 and connected to the accommodating cavity. The wiring terminal 200 is usually arranged in the accommodating cavity near the side wall of the shell 101. In this way, during the wiring process of the contactor 100, it is convenient for the wire to enter the shell 101 from the first wiring hole 103 or the second wiring hole 104 and directly connect to the wiring terminal 200.

[0082] Specifically, the wiring frame 1 is movably arranged in the accommodating cavity at a position close to the side wall of the housing 101, and the opening of the wiring frame 1 faces the first wiring hole 103 and the second wiring hole 104. The first wiring hole 103 is correspondingly connected to the first wiring cavity 11, and the second wiring hole 104 is correspondingly connected to the second wiring cavity 12. During the wiring process of the contactor 100, the user can choose to connect to the first wiring cavity 11 from the first wiring hole 103 according to actual wiring requirements, or can choose to connect to the second wiring cavity 12 from the second wiring hole 104, and of course can also choose to connect from the first wiring hole 103 and the second wiring hole 104 at the same time.

[0083] Reference Fig. 9In some examples, a avoidance hole 1011 is provided on the housing 101 , and the avoidance hole 1011 is adapted to the first baffle 16 . The first baffle 16 can enter the avoidance hole 1011 or close at least part of the second wiring hole 104 as the second frame wall 15 moves.

[0084] Based on the above-mentioned embodiments of the present application, since the length of the first baffle 16 matches the length of the elastic member 5 when it is in a normal state, the setting of the avoidance hole 1011 can be used to avoid the first baffle 16, so that in the process of the wiring frame 1 compressing the elastic member 5, the first baffle 16 can move with the second frame wall 15 and pass through the shell 101, avoiding the first baffle 16 from abutting against the bottom wall of the shell 101 to affect the movement of the wiring frame 1, thereby avoiding affecting the expansion of the second wiring cavity 12.

[0085] Specifically, the first baffle 16 is located between the elastic member 5 and the side wall where the second wiring hole 104 is located. When the second frame wall 15 of the wiring frame 1 moves toward the direction where the static contact plate 102 is located, the first baffle 16 can block the space between the second wiring hole 104 and the second wiring cavity 12. In this way, after the second wiring cavity 12 is closed, the first baffle 16 can partially close the second wiring hole 104, which can not only reduce the risk of electric shock, but also prevent the wire from being mistakenly inserted into the space where the second frame wall 15 is away from the first frame wall 14, thereby reducing the risk of damage to the elastic member 5.

[0086] In addition, refer to Fig. 9 The avoidance hole 1011 is opened at the bottom of the accommodating cavity and is located on the side of the elastic member 5 close to the side wall of the accommodating cavity. The avoidance hole 1011 is connected to the outside. During the movement of the second frame wall 15 of the wiring frame 1 in the direction away from the static contact plate 102, the first baffle 16 connected to the second frame wall 15 can extend out of the housing 101 from the avoidance hole 1011, so that the second frame wall 15 of the wiring frame 1 can be moved to the farthest position away from the static contact plate 102, thereby maximizing the space of the second wiring cavity 12 and facilitating wiring of the second wiring cavity 12.

[0087] In this embodiment, refer to Fig.10 and Fig.11 A second baffle 24 is also provided on the terminal 200. The second baffle 24 is connected to the wire pressing frame 2 and is located between the wire pressing frame 2 and the side wall where the first wiring hole 103 is located. The second baffle 24 can move synchronously with the wire pressing frame 2. When the wire pressing frame 2 moves toward the direction where the static contact plate 102 is located, the second baffle 24 can close at least part of the first wiring hole 103, and can play the role of closing the first wiring hole 103 after the wiring is completed at the first wiring hole 103, thereby further reducing the risk of electric shock and improving the safety of the contactor 100.
