The insulating baffle is riveted to the frame wall of the wire pressing frame, so that the wire pressing frame can stably drive the insulating baffle to move, so that the insulating baffle can be reliably closed at the wiring hole. In addition, the frame wall of the wire pressing frame also facilitates the stable connection of the insulating baffle with it, and multiple groups of riveted structures can be set on the frame wall to improve assembly stability.

[0020] In an optional embodiment, a limiting portion is provided on the insulating baffle, and a limiting groove is provided on the inner wall of the accommodating cavity, and the limiting portion can slide in the limiting groove.

[0021] Based on the above-mentioned embodiments of the present application, the movement direction of the insulating baffle can be limited by the cooperation of the limiting portion and the limiting groove, so that the insulating baffle always covers the wiring hole during the process of wire pressing by the wire pressing structure, thereby avoiding the insulating baffle from being offset or otherwise, and improving the reliability of the insulating baffle in closing the wiring hole.

[0022] In an optional embodiment, a limiting boss is provided on the inner wall of the accommodating cavity, and the limiting boss cooperates with the inner wall of the accommodating cavity to form a limiting groove. Alternatively, the limiting groove is provided on the inner wall of the accommodating cavity.

[0023] In the above-mentioned embodiments of the present application, the setting of the limiting boss can form a limiting groove with the inner wall of the accommodating cavity, and the entire insulating baffle can be limited in the limiting groove. At the same time, the limiting boss can also be used to adapt to the limiting groove opened on the insulating baffle. The limiting boss can also be inserted into the limiting groove to limit the insulating baffle.

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 be electrically connected to the main circuit of the power system and control the on and off of the main circuit. The wiring terminals in the contactor are usually arranged in the housing of the contactor, and the housing of the contactor is provided with wiring holes. The wires of the main circuit can pass through the wiring holes into the housing and connect to the wiring terminals.

[0046] However, since the size of the wiring holes is usually set larger, while it is convenient to connect the wires to the wiring terminals, there are some safety hazards. For example, the user may accidentally touch the wiring terminals in the contactor through the wiring holes, which may lead to the risk of electric shock. Moreover, the electrical connection between the wiring terminals and the wires may be easily affected by external factors, which may lead to the risk of unstable electrical connection, thus affecting the normal use of the contactor.

[0047] Based on this, refer to Figures 1 to 9 The embodiments of the present application provide a wiring terminal and a switch device, which can enhance the protection of the wiring terminal, improve the assembly stability, and thus improve the safety of the switch device.

[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 3 The present embodiment provides a wiring terminal 100, which is arranged in a housing cavity of a housing 201, and the housing cavity is provided with a wiring hole 202. The wiring terminal 100 includes a wiring frame 1, a wire pressing structure 2, and an insulating baffle 3. The wiring frame 1 is installed in the housing cavity. The wire pressing structure 2 is partially located in the wiring frame 1, and the wire pressing structure 2 can move relative to the wiring frame 1. The insulating baffle 3 is riveted to the wire pressing structure 2, and the insulating baffle 3 is located on a side of the wire pressing structure 2 close to the wiring hole 202, and the insulating baffle 3 can close at least part of the wiring hole 202.

[0050] Reference Figure 1 and Figure 2 As a component in the contactor that is directly electrically connected to the external wire, the terminal 100 is usually arranged in the receiving cavity of the contactor housing 201. The housing 201 can protect the terminal 100 accordingly, preventing the terminal 100 from being affected by external factors such as dust or moisture, which may cause unstable electrical connection. At the same time, the terminal 100 is arranged in the receiving cavity of the housing 201 to prevent accidental touch by personnel and reduce the risk of electric shock.

[0051] The wiring hole 202 provided on the accommodating cavity is located on the side wall of the accommodating cavity, and the wiring hole 202 can connect the accommodating cavity with the external environment, so that the external wire can enter the accommodating cavity from the wiring hole 202. In addition, the wiring terminal 100 is arranged in the accommodating cavity near the wiring hole 202, so that the external wire can be connected to the wiring terminal 100.

[0052] The wiring frame 1 in the wiring terminal 100 is usually fixedly arranged in the accommodating cavity, and the wire pressing structure 2 can move relative to the wiring frame 1. During the wiring process of the wiring terminal 100, the external wire enters the accommodating cavity from the wiring hole 202 and is fixed in the wiring frame 1 through the wire pressing structure 2, thereby completing the wiring of the contactor.

[0053] Based on the above-mentioned embodiments of the present application, by setting an insulating baffle 3 on the wiring terminal 100, the wiring terminal 100 can be blocked between the wiring hole 202 and the wiring frame 1 after the wiring is completed, thereby preventing people from contacting the wiring terminal 100 through the wiring hole 202 and reducing the risk of electric shock.

[0054] Specifically, refer to Figure 3 The insulating baffle 3 is arranged on the wire pressing structure 2, so that the insulating baffle 3 can move with the wire pressing structure 2 relative to the wiring frame 1. During the wiring process of the terminal block 100, the wire portion is located in the wiring frame 1. The wire pressing structure 2 moves relative to the wiring frame 1 to press the wire tightly in the wiring frame 1. The insulating baffle 3 moves synchronously during the movement and wire pressing of the wire pressing structure 2, thereby closing the portion of the wiring hole 202 not occupied by the wire, so as to prevent the operator from accidentally reaching into the wiring hole 202 to contact the terminal block 100 or the exposed portion of the wire, thereby effectively reducing the risk of electric shock to personnel and the risk of equipment failure.

[0055] Further, refer to Figure 4 The insulating baffle 3 can be fixedly connected to the wire pressing structure 2 by riveting, which has the characteristics of stable connection, simple structure, and convenient production and assembly.

[0056] In an optional embodiment, the insulating baffle 3 can also be fixedly connected to the wire crimping assembly in other ways. For example, the insulating baffle 3 can be fixedly connected to the wire crimping assembly by clipping or bonding, which has the same technical effect as the above-mentioned riveting form and will not be repeated here.

[0057] Furthermore, the insulating baffle 3 is arranged on one side of the wire pressing structure 2 close to the wiring hole 202. The wire pressing structure 2, the insulating baffle 3 and the wiring hole 202 correspond one to one, so that the insulating baffle 3 can accurately block the opening of the wiring hole 202. In addition, the insulating baffle 3 can close at least part of the wiring hole 202, that is, when the contactor is not connected, the insulating baffle 3 can completely close the wiring hole 202, or it can not close the wiring hole 202. After the contactor is connected, the insulating baffle 3 can close the wiring hole 202 except the part occupied by the wire, effectively reducing the risk of electric shock of the contactor.

[0058] Reference Figure 4 and Figure 5In some embodiments, a rivet column 31 is provided on the insulating baffle 3 , a first rivet hole 21 is provided on the wire pressing structure 2 , and the rivet column 31 is riveted to the wire pressing structure 2 through the first rivet hole 21 .

[0059] Based on the above-mentioned embodiment of the present application, by providing the rivet column 31 on the insulating baffle 3, the assembly operation between the insulating baffle 3 and the wire pressing structure 2 can be simplified. In the process of assembling the insulating baffle 3 to the wire pressing structure 2, the rivet column 31 can play a role in auxiliary positioning, so that the insulating baffle 3 is quickly and accurately connected to the wire pressing structure 2. Compared with the traditional method of providing rivet holes on both the insulating baffle 3 and the wire pressing structure 2 and riveting the two together with rivets, the embodiment of the present application has the characteristics of simple structure, accurate positioning and simple assembly operation.

[0060] Specifically, refer to Figure 4 The rivet post 31 is arranged on the side of the insulating baffle 3 close to the wire pressing structure 2. The arrangement of the rivet post 31 facilitates the positioning and installation of the insulating baffle 3 when it is assembled to the wire pressing structure 2. The insulating baffle 3 can be positioned relative to the wire pressing structure 2 by simply inserting the rivet post 31 into the first rivet hole 21, and then the rivet post 31 and the first rivet hole 21 are riveted together by the riveting operation. On the other hand, the arrangement of the rivet post 31 can accurately distinguish the installation direction of the insulating baffle 3 during assembly, avoiding the situation where the insulating baffle 3 is assembled in the wrong direction.

[0061] In this embodiment, refer to Figure 5 There are two rivet posts 31, and there are also two first rivet holes 21, which correspond one to one with the rivet posts 31. Riveting through two rivet posts 31 and two first rivet holes 21 can prevent the insulating baffle 3 from rotating around a single rivet post 31, thereby effectively improving the riveting stability between the insulating baffle 3 and the wire pressing structure 2.

[0062] In an optional embodiment, the number of riveted columns 31 may be greater than two, and similarly, the first riveted holes 21 are arranged in a one-to-one correspondence with the riveted columns 31. For example, three riveted columns 31 are provided, and three first riveted holes 21 are also provided. The three riveted columns 31 are riveted in a one-to-one correspondence with the three first riveted holes 21, which can further improve the assembly stability. At the same time, the arrangement of the multiple riveted columns 31 on the insulating baffle 3 is the same as the arrangement of the multiple first riveted holes 21 on the wire pressing structure 2, so that the riveted columns 31 can correspond to the first riveted holes 21 one-to-one.

[0063] In another embodiment, a rivet column 31 and a second rivet hole can be simultaneously provided on the insulating baffle plate 3, and a first rivet hole 21 and a rivet column 31 can be correspondingly provided on the wire pressing structure 2. Such a setting enables the rivet column 31 on the insulating baffle plate 3 to be correspondingly inserted into the first rivet hole 21, and the rivet column 31 on the wire pressing structure 2 to be correspondingly inserted into the second rivet hole when the insulating baffle plate 3 is assembled with the wire pressing structure 2. The technical effect of the above-mentioned setting form can also be achieved, which will not be repeated here.

[0064] Reference Figure 4 and Figure 5 In some embodiments, the insulating baffle 3 is provided with an escape portion 32, and the escape portion 32 can escape the external wire.

[0065] Based on the above-mentioned embodiment of the present application, the avoidance portion 32 on the insulating baffle 3 is used to avoid the external wire extending into the wiring hole 202, which can reduce the pressure of the insulating baffle 3 on the external wire, prevent the insulating baffle 3 from wearing the external wire, and improve the wiring stability of the terminal 100. At the same time, the setting of the avoidance portion 32 can only avoid the position of the external wire in the wiring hole 202, and the rest of the wiring hole 202 is completely closed by the insulating baffle 3, further improving safety.

[0066] Specifically, refer to Figure 2 , a wiring board is usually provided in the wiring frame 1 of the wiring terminal 100, and the wire pressing structure 2 will move in the wiring frame 1 toward the location of the wiring board during the wire pressing process to press the external wire onto the wiring board. The avoidance portion 32 is provided on the side of the insulating baffle 3 facing the wiring portion, and during the wire pressing process of the wire pressing structure 2, the insulating baffle 3 moves with the wire pressing structure 2 to gradually close the wiring hole 202. After the wire pressing structure 2 presses the external wire onto the wiring board, the avoidance portion 32 on the insulating baffle 3 approaches or abuts against the external wire, and the space of the wiring hole 202 not occupied by the wire is closed by the portion outside the avoidance portion 32 of the insulating baffle 3. This arrangement effectively increases the closed area of ​​the wiring hole 202 by the insulating baffle 3, further reduces the risk of accidental touch, and improves the safety of the use of the wiring terminal 100.

[0067] In an optional embodiment, the shape of the avoidance portion 32 can be set to be square, circular or other shapes, as long as it can avoid the wire. Exemplarily, the avoidance portion 32 is a circular hole opened on the side of the insulating baffle 3 close to the wiring board. Before the external wire is connected to the wiring terminal 100, it first passes through the circular hole on the insulating baffle 3 and then connects between the wire pressing structure 2 and the wiring board. This can also avoid the wire and meet the sealing effect of the wiring hole 202.

[0068] Reference Figure 4 and Figure 5 In some embodiments, the avoidance portion 32 is an arc-shaped groove.

[0069] Based on the above-mentioned embodiment of the present application, the avoidance portion 32 is set as an arc groove, and the arc groove is opened on the side of the insulating baffle 3 facing the wiring board, that is, the arc opening of the arc groove faces the location of the wiring board, so that during the wire pressing process of the wire pressing assembly, the insulating baffle 3 can move toward the wiring board with the wire pressing assembly and make the arc groove correspondingly avoid the external wire, thereby satisfying the avoidance effect of the insulating baffle 3 on the external wire. In addition, the arc groove has the characteristics of simple structure and easy manufacturing.

[0070] In some embodiments, the projection area of ​​the insulating baffle 3 relative to the side wall of the housing 201 where the wiring hole 202 is located is greater than or equal to the area of ​​the wiring hole 202 .

[0071] Based on the above-mentioned embodiments of the present application, the projection area of ​​the insulating baffle 3 on the side wall of the shell 201 where the wiring hole 202 is located is greater than or equal to the area of ​​the wiring hole 202, which means that the insulating baffle 3 can completely close the wiring hole 202 in both the width and length directions, thereby effectively reducing the risk of accidental touch.

[0072] Among them, the insulating baffle 3 is located between the wiring terminal 100 and the wiring hole 202, and the insulating baffle 3 is close to the wiring hole 202 and is located on one side of the accommodating cavity. By adjusting the gap between the insulating baffle 3 and the wiring hole 202, the insulating baffle 3 can not only have the function of closing part of the wiring hole 202, but also block some external factors such as dust or moisture, avoid affecting the connection stability between the wiring terminal 100 and the external wire, and improve the safety of use of the equipment where the wiring terminal 100 is located.

[0073] Reference Figure 3 and Figure 4 In some embodiments, the wire pressing structure 2 is a wire pressing frame, a frame wall 22 is provided on one side of the wire pressing frame close to the wiring hole 202 , and the insulating baffle 3 is riveted to the frame wall 22 .

[0074] Based on the above-mentioned embodiments of the present application, a wire pressing frame is used as the wire pressing structure 2, which is convenient for wiring with the wiring frame 1 and also convenient for assembling the insulating baffle 3. The insulating baffle 3 is riveted to the frame wall 22 of the wire pressing frame, so that the wire pressing frame can stably drive the insulating baffle 3 to move, so that the insulating baffle 3 can be reliably closed at the wiring hole 202. In addition, the frame wall 22 of the wire pressing frame also facilitates the insulating baffle 3 to be stably connected thereto, and multiple groups of riveted structures can be set on the frame wall 22 to improve assembly stability.

[0075] Specifically, the wire pressing frame is partially sleeved in the wiring frame 1, the opening of the wiring frame 1 faces the wiring hole 202, the wire pressing frame is sleeved in the wiring frame 1, and the frame wall 22 of the wire pressing frame is in the opening direction of the wiring frame 1. Therefore, the insulating baffle 3 is fixedly connected to the frame wall 22 of the wire pressing frame and is located exactly at the opening of the wiring frame 1, that is, it blocks the opening of the wiring frame 1 and the wiring hole 202, thereby achieving the effect of closing the wiring hole 202.

[0076] Among them, a first rivet hole 21 is opened on the frame wall 22 of the wire pressing frame, and the insulating baffle 3 can be riveted to the first rivet hole 21 through the rivet column 31. Multiple first rivet holes 21 or rivet columns 31 can also be set on the frame wall 22, correspondingly connecting the insulating baffle 3 to further improve the assembly stability between the insulating baffle 3 and the wire pressing structure 2.

[0077] Reference Figures 7 to 9 In some embodiments, a limiting portion 33 is provided on the insulating baffle 3 , and a limiting groove 204 is provided on the inner wall of the accommodating cavity, and the limiting portion 33 can slide in the limiting groove 204 .

[0078] Based on the above-mentioned embodiments of the present application, the movement direction of the insulating baffle 3 can be limited by the cooperation of the limiting portion 33 and the limiting groove 204, so that the insulating baffle 3 always covers the wiring hole 202 during the process of pressing the wire with the wire pressing structure 2, thereby avoiding the insulating baffle 3 from being offset or offset, and improving the reliability of the insulating baffle 3 closing the wiring hole 202.

[0079] Specifically, the limiting portion 33 is a side of the insulating baffle 3 parallel to the moving direction, and the limiting groove 204 is located at the inner wall of the accommodating cavity near the wiring hole 202. After the insulating baffle 3 is assembled into the accommodating cavity, the insulating baffle 3 is in the limiting groove 204, and the limiting portions 33 on both sides of the moving direction of the insulating baffle 3 can abut against the groove wall of the limiting groove 204, so that the insulating baffle 3 can always be in the limiting groove 204 and limited by the limiting groove 204 during the movement process. For details, refer to Figure 5 and Figure 8 .

[0080] The limiting portion 33 may also be provided in other forms, and can cooperate with the limiting groove 204 and slide in the limiting groove 204. Exemplarily, the limiting portion 33 is a ridge provided on the insulating baffle 3 toward the inner wall of the accommodating cavity. After the insulating baffle 3 is assembled into the accommodating cavity, the ridge on the insulating baffle 3 is inserted into the limiting groove 204. When the insulating baffle 3 moves with the crimping assembly, the limiting effect of the limiting groove 204 on the ridge enables the insulating baffle 3 to always move along the extension direction of the limiting groove 204. The limiting effect of the limiting groove 204 on the ridge can also prevent the insulating baffle 3 from being offset or falling off, thereby effectively improving the assembly stability.

[0081] Furthermore, a limiting groove 204 may be provided on the insulating baffle 3 , and a limiting portion 33 may be provided on the inner wall of the accommodating cavity. The insulating baffle 3 may also be limited by the cooperation of the two limiting portions 33 and the limiting groove 204 .

[0082] Reference Figure 8 and Fig. 9 In some embodiments, a limiting boss 203 is provided on the inner wall of the accommodating cavity, and the limiting boss 203 cooperates with the inner wall of the accommodating cavity to form a limiting groove 204. Alternatively, the limiting groove 204 is provided on the inner wall of the accommodating cavity.

[0083] Based on the above-mentioned embodiments of the present application, the setting of the limiting boss 203 can form a limiting groove 204 with the inner wall of the accommodating cavity, and the insulating baffle 3 can be completely limited in the limiting groove 204. At the same time, the limiting boss 203 can also be used to adapt to the limiting groove 204 opened on the insulating baffle 3. The limiting boss 203 can also be inserted into the limiting groove 204 to limit the insulating baffle 3. Therefore, the setting of the limiting boss 203 facilitates the assembly of the insulating baffle 3, and has a simple structure and a wide range of applications.

[0084] Specifically, refer to Fig. 9 There are two limiting bosses 203, which are arranged on the inner wall of the accommodating cavity and located on the opposite sides of the wiring hole 202. A limiting groove 204 is formed between the two limiting bosses 203. The two side edges of the insulating baffle 3 parallel to the moving direction respectively abut against the opposite side walls of the two limiting bosses 203, thereby limiting the insulating baffle 3.

[0085] In another embodiment, two parallel limiting grooves 204 are provided on one side of the insulating baffle 3 facing the wiring hole 202, and the two parallel limiting grooves 204 correspond to the two limiting bosses 203 one by one, so that the insulating baffle 3 can also be limited. Therefore, the setting of the limiting boss 203 can satisfy two limiting modes at the same time, and has high practicality.

[0087] Based on the above-mentioned embodiments of the present application, the guide structure 34 can play a guiding role when the insulating baffle 3 is assembled into the accommodating cavity. The guide structure 34 is connected to the limiting portion 33 so that the limiting portion 33 on the insulating baffle 3 can smoothly enter the limiting groove 204, thereby facilitating the smooth assembly of the insulating baffle 3 into the accommodating cavity.

[0088] Among them, the guide structure 34 can be a chamfer set on the insulating baffle 3, such as a rounded corner, a chamfered right angle or other types of chamfers. The guide structure 34 is set on the side of the insulating baffle 3 close to the terminal board, that is, the side where the arc groove on the insulating baffle 3 is located. When the insulating baffle 3 is assembled into the accommodating cavity, the side of the insulating baffle 3 close to the terminal board first abuts against the limit groove 204. Under the action of the guide structure 34, the limit part 33 can smoothly enter the limit groove 204, thereby completing the role of guiding installation.
