Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] According to an embodiment of the present utility model, a wiring component is provided. Please refer to Figures 1 to 5, including: a terminal 1, the terminal 1 includes a first wiring component 11 and a second wiring component 12, the first wiring component 11 and the second wiring component 12 are connected, the first wiring component 11 is used for connecting a wire, a limiting plate 13 is arranged on the second wiring component 12, and the limiting plate 13 protrudes from the second wiring component 12; a conductive sheet 2, a groove 21 is arranged on the conductive sheet 2, the groove 21 is arranged corresponding to the limiting plate 13, when the terminal 1 is connected to the conductive sheet 2, the limiting plate 13 is clamped in the groove 21. The limiting plate 13 on the terminal 1 is clamped in the groove 21 of the conductive sheet 2, which not only effectively prevents quality problems caused by improper insertion, but also avoids the risk of burning out the contactor terminal due to poor contact; at the same time, it can also be used as an installation guide through the adaptation of the limiting plate 13 and the groove 21, improving the assembly efficiency. In short, the wiring component is structurally designed with anti-fooling for plugging to avoid after-sales quality problems caused by improper plugging, improve the reliability of the unit, and the terminal limiting structure improves the assembly efficiency. The wiring component of this embodiment solves the technical problem in the related art that the existing terminal is extremely easy to be connected wrongly, resulting in poor contact and easily burning out the contactor terminal.

[0029] Refer to Figure 1 , for the wiring component of this embodiment, the limiting plate 13 is arranged at one end of the second wiring component 12 away from the first wiring component 11, and the limiting plate 13 is vertically arranged on the second wiring component 12. It is equivalent to setting a hem at the end where the terminal 1 contacts the conductive sheet 2 and inserting the hem into the groove 21 of the conductive sheet 2 and clamping it.

[0030] Refer to Figure 1 , for the wiring component of this embodiment, the first wiring component 11 is of a cylindrical structure, and a fixing hole 111 is arranged on the first wiring component 11, and the wire passes through the fixing hole 111. The first wiring component 11 is used for threading and fixing the wire.

[0031] Refer to Figure 2 、 Figure 3 and Figure 4 , for the wiring component of this embodiment, a screw hole 22 is further arranged on the conductive sheet 2, the wiring component further includes a wire pressing component 3, the wire pressing component 3 includes a wire pressing piece 31 and a wire pressing screw 32, the wire pressing piece 31 is sleeved on the wire pressing screw 32, the wire pressing screw 32 is screwed with the screw hole 22, and a part of the second wiring component 12 is located between the conductive sheet 2 and the wire pressing piece 31, so that the wire fixed on the terminal 1 is clamped between the conductive sheet 2 and the wire pressing piece 31. During assembly in the wire pressing groove 6, the wire passes through the fixing hole 111 to the lower part of the second wiring component 12, the wire pressing screw 32 passes through the screw hole 22 and is connected to the conductive sheet 2, and in order to increase the wire pressing area, the wire pressing piece 31 is arranged. The wire pressing screw 32 rotates to drive the wire pressing piece 31 to press a part of the second wiring component 12 (such as Figure 3As shown, the wire core located below the second wiring component 12 is clamped between the conductive sheet 2, the second wiring component 12, and the wire pressing sheet 31.

[0032] Refer to Figure 2 , in the wiring assembly of this embodiment, the wire pressing sheet 31 is an arc-shaped sheet structure, and the convex surface of the wire pressing sheet 31 abuts against the nut 321 of the wire pressing screw 32. The wire pressing sheet 31 is in an arc-shaped sheet structure. On the one hand, it is convenient to fit with the arc-shaped second wiring component 12. On the other hand, its four top corners can press the wire like a clamping jaw, so that the wire is not easily detached after being pressed.

[0033] Refer to Figure 4 , in the wiring assembly of this embodiment, the wire pressing assembly 3 further includes a support ring 33. The support ring 33 is sleeved on the threaded rod 322 of the wire pressing screw 32, and the support ring 33 abuts against the concave surface of the wire pressing sheet 31. During the process of loosening the wire pressing screw 32, if the wire pressing screw 32 becomes loose and the wire pressing sheet 31 does not move, the distance between the arc-shaped wire pressing sheet 31 and the nut 321 is too large, and it is very easy for the wiring terminal 1 to be inserted between the wire pressing sheet 31 and the nut 321, resulting in an improper insertion situation. The setting of the support ring 33 is to ensure that the wire pressing sheet 31 can move along with the movement of the threaded rod 322 and prevent the wiring terminal 1 from being wrongly inserted.

[0034] Refer to Figure 4 , in the wiring assembly of this embodiment, the wire pressing assembly 3 further includes a snap ring 34. The snap ring 34 is sleeved on the threaded rod 322, and the snap ring 34 is located at one end of the threaded rod 322 away from the support ring 33; the wiring assembly further includes an insulating seat 4 and a limit buckle 5. The limit buckle 5 is fixed on the insulating seat 4. There are two limit buckles 5 and they are symmetrically arranged. When the snap ring 34 is located between the two limit buckles 5, the wire pressing screw 32 is connected to the insulating seat 4 through the two limit buckles 5. The two limit buckles 5 are symmetrically arranged to clamp the snap ring 34.

[0035] Refer to Figure 4 , in the wiring assembly of this embodiment, the limit buckle 5 includes a connecting plate 51 and a blocking plate 52. One end of the connecting plate 51 is connected to the insulating seat 4, and the other end of the connecting plate 51 is connected to the blocking plate 52. When the snap ring 34 is located between the two limit buckles 5, the two blocking plates 52 are used to block the snap ring 34 from moving out of the limit buckle 5. With this setting, it is prevented that the wire pressing screw 32 is completely withdrawn during the process of loosening the wire pressing screw 32, causing the loss or dropping of the wire pressing screw 32, ensuring the normal operation of the production operation and guaranteeing the assembly efficiency.

[0036] Refer to Figure 5 , in the wiring assembly of this embodiment, a notch 521 is provided at the edge of the blocking plate 52. The notch 521 is located on the side of the blocking plate 52 away from the insulating seat 4. The notch 521 is for facilitating the snap ring 34 on the threaded rod 322 to enter the two limit buckles 5.

[0037] Refer to Figure 4 and Figure 5 For the wiring assembly of this embodiment, the threaded rod 322 includes a first threaded rod 3221 and a second threaded rod 3222. One end of the first threaded rod 3221 is connected to the nut 321, and the other end of the first threaded rod 3221 is connected to the second threaded rod 3222. The support ring 33 is located on the first threaded rod 3221, and the snap ring 34 is located on the second threaded rod 3222. The diameter of the first threaded rod 3221 is larger than that of the second threaded rod 3222. The large diameter of the first threaded rod 3221 is to increase the contact surface with the conductive sheet 2 and the insulating seat 4 and improve the connection stability; the small diameter of the second threaded rod 3222 is to be adapted to the bottom of the insulating seat 4 and reduce the occupied space of the limit buckle 5 on the insulating seat 4.

[0038] The wiring assembly of the present utility model is applicable to the terminal fixation of a large-current wiring device. The limit connector terminal structure is designed to prevent misinsertion and ensure reliable connection at the correct fixed position of the inserted wiring device, avoiding poor contact and burning out the terminal. When the pressure screw 32 is loosened, the pressure piece 31 is lifted, synchronously guiding the wiring terminal 1 to reach the correct installation position below the pressure piece 31. The wiring terminal 1 is snapped into the groove 21 of the conductive sheet 2, and the pressure screw 32 is tightened. After the terminal is equipped, it is as Figure 4 shown. This design avoids the problem of burning out the wiring device caused by the improper insertion and fixation of the contactor terminal.

[0039] In the electrical equipment of this embodiment, a limiting plate 13 is provided at the top of the terminal 1. The limiting plate can be in the form of a bend and is used in cooperation with the groove 21 of the wiring device fixing part (i.e., the conductive sheet 2). When the terminal 1 is inserted, the limiting plate 13 is snapped into the groove 21 of the conductive sheet 2. In this structure, since the limiting plate 13 is equivalent to a 1-2 mm hem on the second wiring component 12, misinsertion can be avoided. The limiting groove 21 is provided on the conductive sheet 2 of the wiring device. The depth of the groove 21 is 1-2 mm, the width is 2-3 mm, and the length is the same as that of the limiting plate 13. The groove 21 catches the limiting plate 13 on the terminal to prevent the terminal from being inserted incompletely. A support ring 33 and a snap ring 34 are designed on the pressure screw 32 of the wire pressing assembly 3. During the process of loosening the pressure screw 32, the support ring 33 ensures that the pressure piece 31 can move along with the movement of the screw, preventing the pressure piece 31 from remaining stationary when the pressure screw 32 becomes loose and avoiding the situation where the distance between the pressure piece 31 and the nut 321 is too large, resulting in incomplete insertion. The diameter of the tail of the threaded rod 322 is smaller than that of the upper part. A limiting buckle 5 is designed on the insulating seat 4, and the diameter here is smaller than that of the upper screw, facilitating entry into the limiting buckle 5. The snap ring 34 and the limiting buckle 5 can prevent the pressure screw 32 from being completely withdrawn during the process of loosening the pressure screw 32, causing the screw to be lost or dropped. The limiting buckle 5 is designed as a dead buckle. The total height of the limiting buckle 5 is 20 mm, the width is 20 mm, and the thickness is 5 mm. The upper top surface of the limiting buckle 5 is designed as a 45° slope (i.e., the notch 521), and the lower bottom surface remains rectangular, as Figure 5 shown. This structure is conducive to driving the pressure screw 32 in. When the pressure screw 32 is driven in, the limiting buckle 5 is pushed open to both sides. The bottom surface of the insulating seat 4 is flat. After the pressure screw 32 enters, both the snap ring 34 on the second threaded rod 3222 and the bottom surface of the limiting buckle 5 are flat. The second threaded rod 3222 cannot push the limiting buckle 5 open anymore when moving upward, thus playing a limiting role.
