[0002] A terminal block is a device used to connect wires to electrical equipment, and includes a post-shaped terminal. The post-shaped terminal typically secures the wire to the terminal by screwing a fastener (such as a screw) into the terminal, causing the end of the fastener to press against the terminal.

[0003] However, this fixing method still has problems such as poor fixing stability between the wire and the terminal, and the fastener is likely to damage the wire when pressing the wire. Utility Model Content

[0036] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0037] It should be noted that the titles of any section / subsection provided herein are not limiting. Various embodiments are described throughout this document, and any type of embodiment may be included under any section / subsection. Furthermore, the embodiments described in any section / subsection may be combined in any manner with any other embodiments described in the same section / subsection and / or in different sections / subsections.

[0038] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may be included below. The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0039] As briefly mentioned above, the wiring mechanism of the switch device includes a cylindrical terminal, which is fixed to the housing of the device, and the fastener is threadedly engaged with the terminal. Through the threaded engagement of the fastener and the terminal, the end of the fastener can press the wire against the side wall of the terminal opposite the fastener (also called the power-connected side wall of the terminal). This fixing method means that when the fastener presses the wire, in addition to the pressure acting on the wire perpendicular to the power-connected side wall, there is also a shear force acting on the wire rotating around the axis, which can easily damage the wire. In some traditional solutions, in order to reduce the damage to the wire when the fastener is tightened, the end of the fastener is processed into a hemispherical or spherical crown shape. However, such treatment will reduce the wire pressing effect between the wire and the terminal, resulting in an excessive temperature rise at the connection between the wire and the terminal. At the same time, for multi-core wires, the wire is also easily stuck in the gap between the fastener and the terminal, affecting the electrical performance of the power-connected terminal.

[0040] In addition, to prevent the fastener from falling off the terminal, after the fastener is threaded into the terminal, the end of the fastener needs to be cold-forged to deform the end of the fastener and get stuck in the terminal. However, such a processing technique is complicated, resulting in a low yield rate of the product. At the same time, when the fastener is rotated until the end of the fastener abuts against the edge of the screw hole of the terminal, the threaded engagement of the fastener and the screw hole causes the end of the fastener to exert too much force on the edge of the screw hole, which can easily damage the terminal. Another method is to arrange a plastic part on one side of the fastener head, and limit the rotation of the fastener by limiting the position of the fastener head with the plastic part. However, this method also has the problem of damage to the plastic part due to excessive pressure exerted on the plastic part by the threaded engagement when the fastener is screwed.

[0041] According to the embodiments of the present disclosure, a wire crimping device, a wiring mechanism, and an electrical device for a wiring mechanism are proposed to solve or at least partially solve the above-mentioned problems and other potential problems existing in traditional solutions. According to various embodiments of the present disclosure, by coupling a wire crimping device to a fastener of the wiring mechanism, and arranging the wire crimping portion of the wire crimping device at the end of the fastener, when it is necessary to fix the wire, the fastener rotates relative to the wiring terminal, and the end of the fastener pushes the wire crimping portion toward the side wall of the wiring terminal facing the fastener (also called the power-connecting side wall), and the wire is pressed between the wire crimping portion and the power-connecting side wall. The arrangement of the wire crimping device improves the stability of the fixation of the wire to the wiring terminal, while reducing the damage to the wire caused by the fastener. On the other hand, after the wire crimping device fixes the wire, the connecting portion of the wire crimping device can also block the wiring hole of the wiring mechanism housing, thereby reducing user misoperation.

[0042] The electrical device according to the embodiment of the present disclosure includes the above-mentioned wiring mechanism with the wire pressing device. The electrical device mentioned herein may include but is not limited to: any electrical device requiring a wiring mechanism, such as a switch or a socket. Figure 1 The figure shows the overall structure of the wiring mechanism of the embodiment of the present disclosure installed in the electrical device, wherein the wire pressing device of the neutral wire and the live wire connected to the circuit of the electrical device is in the unlocked position, and the wire pressing device of the ground wire is in the locked position. Figure 1 As shown, the wiring mechanism includes a housing 6, a terminal 5 coupled to the housing 6, a fastener 4 threadedly engaged with the terminal 5, and a wire pressing device coupled to the fastener 4. When a wire is inserted into the terminal 5 and the fastener 4 rotates relative to the terminal 5, the fastener 4 can drive the wire pressing device to move from an unlocked position where it maintains a distance from the wire to a locked position where it presses the wire against the terminal 5.

[0043] In some embodiments, the housing 6 further defines a wiring hole 62 for exposing the wiring terminal 5. A wire can pass through the wiring hole 62 and be inserted into the wiring terminal 5. When the wire-pressing device presses the wire against the power-connecting side wall, the connecting portion 3 of the wire-pressing device slides to the wiring hole 62 and is adapted to block the wiring hole 62, thereby preventing the user from mishandling the wiring.

[0044] Furthermore, in some embodiments, the color of the terminal block 5 can be different from the color of the connector 3, so that when the wire crimping device is in the unlocked position, the user can observe the color of the terminal block 5 through the wiring hole 62, and when the wire crimping device is in the locked position, the user can observe the color of the connector 3 through the wiring hole 62. In this way, the position and status of the wire crimping device can be intuitively indicated to the user through different colors, thereby improving the reliability of the wiring mechanism and the user experience.

[0045] Figures 2 to 6 Schematic diagrams of a portion of a wiring mechanism of some embodiments of the present disclosure at various viewing angles are shown, with the wire pressing device in an unlocked position. Figures 2 to 6 As shown, in some embodiments, the fastener 4 mentioned above can be a screw. The fastener 4 includes a screw portion 41 and a head 42 coupled to one end of the screw portion 41. Hereinafter, the end of the screw portion 41 of the fastener 4 away from the head 42 will be referred to as the end of the fastener 4. The terminal 5 is provided with a screw hole that cooperates with the screw portion 41. Correspondingly, the screw portion 41 includes a threaded section 412. When the screw portion 41 is inserted into the screw hole, the threaded section 412 can threadably engage with the screw hole.

[0046] Figures 7 to 11 Schematic diagrams showing various perspectives of the wiring mechanism of the embodiment of the present disclosure in a locked state, in which the wire pressing device is in a locked position. Figures 7 to 11As shown, in some embodiments, the screw portion 41 of the fastener 4 may further include a first polished rod segment 411 and a second polished rod segment 413. The first polished rod segment 411 is disposed at the end of the threaded segment 412 facing the head 42, and the second polished rod segment 413 is disposed at the end of the threaded segment 412 facing away from the head 42. The first polished rod segment 411 and the second polished rod segment 413 will be described in detail below.

[0047] like Figures 2 to 11 As shown, the wire crimping device includes a coupling portion 1 coupled to the fastener 4, a wire crimping portion 2 arranged at the end of the fastener 4 (i.e., the end of the screw portion 41 away from the head 42), and a connecting portion 3 arranged between the coupling portion 1 and the wire crimping portion 2. In some embodiments, the coupling portion 1 can be coupled to the first bare rod segment 411 of the screw portion 41, as will be further described below. The connecting portion 3 is arranged on the same side of the coupling portion 1 and the wire crimping portion 2 along their respective extension directions L. The two ends of the connecting portion 3 are respectively coupled to the connecting portion 3 and the coupling portion 1, thereby coupling the coupling portion 1 and the wire crimping portion 2 together through the connecting portion 3. When it is necessary to lock or unlock the guide wire, the user drives the head of the fastener 4 to rotate the fastener 4 around its own axis. During this process, the threaded segment 412 of the fastener 4 engages with the thread of the screw hole on the terminal 5 and approaches the power-connected side wall of the terminal 5 opposite the screw hole, allowing the wire crimping device to move toward the power-connected side wall along the axis of the fastener 4.

[0048] In some embodiments, the wire pressing device can be integrally formed, that is, the coupling portion 1, the connecting portion 3, and the wire pressing portion 2 can be integrally formed. For example, the coupling portion 1, the connecting portion 3, and the wire pressing portion 2 can be formed by bending a profile. In some alternative embodiments, the coupling portion 1, the connecting portion 3, and the wire pressing portion 2 can also be integrally injection molded. In other embodiments, the coupling portion 1, the connecting portion 3, and the wire pressing portion 2 can also be separately formed and coupled together by methods such as welding, bonding, and clamping.

[0049] Figure 12 and Figure 13 The overall structural diagrams of the wire pressing devices of some embodiments of the present disclosure are shown respectively. Figure 12 and Figure 13As shown, in some embodiments, the coupling portion 1 includes a receiving groove 11, the width of the receiving groove 11 is greater than the diameter of the first light rod segment 411, so that the receiving groove 11 can allow the first light rod segment 411 to be at least partially embedded in the receiving groove 11. The first light rod segment 411 can rotate freely around its own axis in the receiving groove 11. In some embodiments, the receiving groove 11 can be a circular hole with an opening in the radial direction, and the width of the receiving groove 11 mentioned above is also the diameter of the circular hole. The diameter of the circular hole (that is, the width of the receiving groove 11) is smaller than the diameter of the threaded segment 412, so that when the fastener 4 rotates around its own axis relative to the terminal 5, the edge of the receiving groove 11 is pushed by the end of the threaded segment 412, so that the wire pressing device will not axially disengage from the receiving groove 11.

[0050] It is mentioned above that the screw portion 41 also includes a second polished rod section 413 (i.e., located at the end of the fastener) that is arranged at one end of the threaded section 412 away from the first polished rod section 411. The diameter of the second polished rod section 413 is smaller than the diameter of the screw (correspondingly, the second polished rod section 413 is also smaller than the inner diameter of the screw hole of the terminal 5). Thus, when the fastener 4 rotates around its own axis in the direction away from the power-connected side wall, the wire pressing device moves away from the power-connected side wall with the fastener 4. When, for example, the wire is unlocked, as the fastener rotates, when the threaded section 412 turns out of the screw hole and the second polished rod section 413 enters the screw hole, the fastener 4 and the terminal 5 release the threaded fit, so that the second polished rod section 413 of the fastener 4 can rotate freely in the screw hole, and the fastener 4 and the wire pressing device will not axially displace as the fastener 4 rotates. At this time, the wire pressing portion 2 of the wire pressing device abuts the side wall of the terminal 5 with the screw hole, and then the wire pressing device and the fastener 4 are restricted on the terminal 5 to avoid the fastener 4 from falling off. Since the fastener 4 and the terminal 5 are no longer threadedly engaged at this time, the situation where the fastener 4 is excessively rotated and damages the terminal 5 is reduced.

[0051] In some embodiments, such as Figure 12 As shown, the radial opening of the accommodating groove 11 is oriented along the extension direction L of the coupling portion 1 or the wire pressing portion (or parallel to the extension direction L) and is located on the side away from the connecting portion 3, so that the first polished rod segment 411 of the fastener 4 can be installed in the accommodating groove 11 through the radial opening. When the wire pressing device is coupled to the fastener 4, the wire pressing device can be limited by the structure of the housing 6, so that the first polished rod segment 411 can be retained in the accommodating groove 11.

[0052] In some embodiments, the opening direction of the accommodating groove 11 may also be perpendicular to the extending direction L of the coupling portion 1 or the wire pressing portion. Figure 13 and Figure 14 As shown, the contact between the side wall of the accommodating groove 11 and the first polished rod segment 411 can reduce the possibility of the wire pressing device being separated from the fastener 4 along the extension direction L.

[0053] In some embodiments, the coupling portion 1 further includes a pair of clamping blocks 12. The pair of clamping blocks 12 are respectively arranged on two opposing side walls of the accommodating groove 11, and the clamping blocks 12 are located on the side of the side wall closest to the opening. When the first polished rod segment 411 is inserted into the accommodating groove 11, the first polished rod segment 411 elastically deforms the clamping blocks 12 and the opening to a certain extent, thereby facilitating the first polished rod segment 411 to enter the accommodating groove 11. After the first polished rod segment 411 is inserted into the accommodating groove 11, the pair of clamping blocks 12 can respectively abut against the circumferential surface of the first polished rod segment 411. By limiting the position of the first polished rod segment 411 by the pair of clamping blocks 12, the coupling portion 1 can be coupled to the first polished rod segment 411 in a snap-fit ​​manner, thereby improving the stability of the coupling between the coupling portion 1 and the first polished rod segment 411.

[0054] In some embodiments, to facilitate the entry of the first polished rod segment 411 into the accommodating groove 11, the radial opening of the accommodating groove 11 may be trumpet-shaped, i.e., radially smaller inward and larger outward, thereby facilitating the entry of the first polished rod segment 411 into the accommodating groove 11. In some embodiments, the clamping block 12 may also be formed by the cooperation of the trumpet-shaped opening and the circular hole-shaped accommodating groove 11.

[0055] The wire pressing portion 2 is arranged at the end of the fastener 4 (that is, the end of the second rod section 413 away from the threaded section 412) and abuts against the end of the fastener 4. When the fastener 4 rotates around its own axis and the fastener 4 is screwed into the electrical side wall of the terminal 5, the end of the fastener 4 pushes the wire pressing portion 2 to move. When the user needs to connect the wire to the terminal 5, the user puts the wire into the terminal 5 and makes the wire be located on the side of the wire pressing portion 2 away from the fastener 4, so that the fastener 4 rotates around its own axis. Through the threaded fit between the fastener 4 and the screw hole of the terminal 5, the end of the fastener 4 pushes the wire pressing portion 2 to press the wire onto the terminal 5. The pressure exerted by the wire pressing portion 2 on each part of the wire is more uniform, thereby improving the stability of the electrical connection between the wire and the terminal 5. On the other hand, since the end of the fastener 4 does not directly contact the wire, the situation in which the wire is damaged by the shear force when the fastener 4 rotates is reduced.

[0056] In some embodiments, a plurality of anti-slip grooves 21 are arranged on a side of the wire pressing portion 2 facing away from the fastener 4. The plurality of anti-slip grooves 21 are arranged along the extension direction L, and the length direction of each anti-slip groove 21 is arranged to form a predetermined non-zero angle with the extension direction L. For example, the length direction of each anti-slip groove 21 can be perpendicular to the extension direction L. When the wire pressing portion 2 presses the wire against the power-connecting side wall of the terminal block 5, the plurality of anti-slip grooves 21 can increase the friction between the wire pressing portion 2 and the wire, thereby improving the stability of the wire being fixed.

[0057] In some alternative embodiments, the anti-slip groove 21 can also be replaced with an anti-slip strip protruding from the surface of the wire pressing portion 2. The length direction of each anti-slip strip and the arrangement of the multiple anti-slip strips are similar to the arrangement of the anti-slip groove 21 and will not be repeated here. When the wire pressing portion 2 is pressed against the power connection side wall, the anti-slip strip can also increase the friction of the wire pressing portion 2, thereby improving the stability of the wire fixed to the terminal 5.

[0058] In certain embodiments, the wire pressing portion 2 may include a side limiting groove arranged toward the fastener 4 to at least partially accommodate the end of the fastener 4. The limiting groove can provide a limit for the end of the fastener 4 to improve the firmness of the fastener 4 and the wire pressing device, and improve reliability. In addition, the limiting groove also allows the end of the fastener 4 to accurately push against the predetermined position of the wire pressing portion 2, so that the pressure distribution of the wire pressing portion 2 when compressing the wire is more uniform. In certain embodiments, the limiting groove can be formed by bending the middle section of the wire pressing portion 2 in a direction away from the fastener 4.

[0059] In some embodiments, the side of the wire pressing portion 2 facing the power supply side wall is arranged to be compatible with the power supply side wall. For example, if the surface of the power supply side wall is flat, the side of the wire pressing portion 2 facing the power supply side wall is correspondingly arranged as a flat surface. If the surface of the power supply side wall is a curved surface that is concave in the direction away from the fastener 4, the side of the wire pressing portion 2 facing the power supply side wall can also be arranged as an arc surface that is arched in the direction away from the fastener 4. This allows the side of the wire pressing portion 2 facing the power supply side wall to better fit the power supply side wall, ensuring that the wire pressing portion 2 can stably press the wire against the power supply side wall.

[0060] Figure 15 FIG. 5 is a schematic diagram showing a wire pressing device according to an embodiment of the present disclosure installed in a housing 6. Figure 15 As shown, in some embodiments, the connecting portion 3 includes a limiting bar hole 31, and the length direction of the limiting bar hole 31 is parallel to the axial direction of the fastener 4. Correspondingly, the shell 6 also includes a limiting bar 61, and the length direction of the limiting bar 61 is parallel to the axial direction of the fastener 4. When the wire pressing device is coupled to the fastener 4 and installed inside the shell 6 along with the fastener 4, the limiting bar 61 is snapped into the limiting bar hole 31. Through the cooperation between the limiting bar 61 and the limiting bar hole 31, on the one hand, the wire pressing device can be more stably limited inside the shell 6, thereby improving the stability of the wire pressing device installed inside the shell 6. On the other hand, when the fastener 4 rotates, the wire pressing device can also be more stably displaced along the axial direction of the fastener 4 along the fastener 4.
