Description

Technical Field

[0001] The present invention belongs to the technical field of electrical equipment, and in particular relates to a conductive wiring assembly and electrical equipment having the same. Background Art

[0002] At present, the terminal installation connection and locking method of the terminal post used in high-power electrical equipment is generally thread locking, mainly in the form of screw rod with nut connection or bolt connection. The current is transversely transmitted from the thread of the terminal post to the nut (or bolt), and then transmitted from the end face of the nut (bolt cap) to the terminal. As a connector and current transmission component between the terminal post and the terminal, the nut is prone to cause severe heating of the terminal post and even sparks due to its limited current-carrying area and poor conductivity, thereby damaging the terminal post and the motor. In addition, the method of locking the terminal post with nuts or bolts has the following two main disadvantages: First, it is inconvenient to install and disassemble. When connecting the terminal post, a torque wrench with a specific torque is usually required to lock the nut or screw. The process is cumbersome, and the space required for the operation is large, which is not suitable for occasions with narrow working space; second, frequent disassembly and assembly of the locking nuts or bolts on the terminal post will cause serious damage to the threads or the terminal post, affecting the connection strength and effective current-carrying area of ​​the terminal post, which will pose a great electrical safety hazard in the long run. Summary of the invention

[0003] Therefore, the present invention provides a conductive terminal assembly, which can solve the technical problem that the existing terminal post uses a nut or bolt to lock the terminal. Frequent disassembly and assembly of the locking nuts or bolts on the terminal will cause serious damage to the threads or the terminal, affecting the connection strength and effective current-carrying area of ​​the terminal, which will pose a great electrical safety hazard in the long run.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0038] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0039] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0040] See also Figures 1 to 14As shown, according to an embodiment of the present invention, a conductive wiring assembly is provided, comprising: a conductive rod 1, a locking assembly 2 and a wiring terminal 3, the conductive rod 1 comprising a locking section 11, the locking section 11 being provided with a slot 4, the wiring terminal 3 having a claw 32, the wiring terminal 3 being assembled on the locking section 11, the locking assembly 2 having a locked state and an unlocked state, in the locked state, the locking assembly 2 compresses the claw 32 so that the claw 32 engages with the slot 4, in the unlocked state, the locking assembly 2 releases the pressure on the claw 32 so that the claw 32 escapes from the slot 4.

[0041] In this technical solution, when the locking assembly 2 is in the locked state, the locking assembly 2 will press the claw 32 of the terminal 3, so that the claw 32 is engaged with the slot 4, so that the locking assembly 2 locks the terminal 3 on the conductive rod 1, thereby also realizing the installation of the terminal 3; when the locking assembly 2 is in the unlocked state, the locking assembly 2 will release the pressure on the claw 32, so that the claw 32 escapes from the slot 4, so that the locking assembly 2 unlocks the terminal 3 and the conductive rod 1, thereby also realizing the disassembly of the terminal 3. Compared with the method of locking the terminal 3 with nuts or bolts in the prior art, the present application adopts such a locking method for the terminal 3. During the process of disassembling and assembling the terminal 3, no damage will be caused to any components, so it will not affect the connection strength and effective current-carrying area of ​​the conductive wiring assembly, there is no electrical safety hazard, and the service life of the conductive wiring assembly can be extended. The terminal block 3 further comprises a wiring portion 31, the wiring portion 31 has a receiving cavity for receiving an external power line, and the claw 32 is located on the wiring portion 31, and is located on one axial side of the wiring portion 31 and away from the opening of the receiving cavity. Preferably, the conductive rod is a copper rod, and the copper rod is made of a copper metal material with low resistance, good conductivity, and corrosion resistance, such as T3, H62, etc. The terminal block 3 is made of a metal material with low resistance, good conductivity, corrosion resistance, wear resistance, and good ductility, such as copper, aluminum, etc.

[0042] See also Figure 1 , Figure 5 and Figure 7As shown, the locking assembly 2 includes a locking sleeve 21, which is simultaneously sleeved around the claw 32 and the locking section 11. In the locked state, the locking sleeve 21 shrinks to compress the claw 32, and in the unlocked state, the locking sleeve 21 expands to release the compression of the claw 32. The locking sleeve 21 is simultaneously sleeved around the claw 32 and the locking section 11. In the process of shrinking and expanding the locking sleeve 21, not only can the claw 32 and the slot 4 be engaged or not, but the locking sleeve 21 also limits the claw 32 and the locking section 11 in the circumferential direction, so that the terminal 3 can be more firmly locked on the locking section 11 of the conductive rod 1. In addition, an elastic ring can also be used to tighten the claw 32 and the locking section 11 at the same time. The elastic ring will compress the claw 32 under the action of the elastic contraction force so that the claw 32 and the slot 4 are engaged. At the same time, removing the elastic ring will release the pressure on the claw 32 so that the claw 32 can fall out of the slot 4.

[0043] See also Figures 3 to 5 As shown, a side opening 5 is formed on the wall of the locking sleeve 21 , the side opening 5 penetrates the axial direction of the locking sleeve 21 , and the side opening 5 is communicated with the interior of the locking sleeve 21 .

[0044] In this embodiment, when the side opening 5 is formed on the wall of the locking sleeve 21, the locking sleeve 21 is easily deformed. When the locking sleeve 21 is subjected to force, the side opening 5 becomes smaller or disappears, making the locking sleeve 21 smaller, and the locking sleeve 21 will press the claw 32, so that the locking assembly 2 is in a locked state; when the force on the locking sleeve 21 is released, the locking sleeve 21 will expand and return to a natural state, and the locking sleeve 21 will release the pressure on the claw 32, so that the locking assembly 2 is in an unlocked state.

[0045] See also Figures 3 to 5 As shown, a first pressing body 22 and a second pressing body 23 are provided on the locking sleeve 21 . Along the circumference of the locking sleeve 21 , the first pressing body 22 and the second pressing body 23 are respectively located on both sides of the side opening 5 .

[0046] In this technical solution, the locking sleeve 21 can be deformed and reduced by applying force to the first pressing body 22 and / or the second pressing body 23, and only a small force is required to achieve the deformation of the locking sleeve 21. That is, the provision of the first pressing body 22 and the second pressing body 23 makes it more convenient and labor-saving to apply force to the locking sleeve 21.

[0047] See also Figure 3 , Figure 4 and Fig.13As shown, the first pressing body 22 has an extension portion 24, which extends in the direction of the second pressing body 23 and exceeds the second pressing body 23. A rotatable cam 25 is provided on the extension portion 24, and the second pressing body 23 is located between the cam 25 and the first pressing body 22; the cam 25 has a first position and a second position, and when the cam 25 is in the first position, the cam 25 presses the second pressing body 23 to put the locking assembly 2 in a locked state; when the cam 25 is in the second position, the cam 25 releases the pressure on the second pressing body 23 to put the locking assembly 2 in an unlocked state.

[0048] In this embodiment, when the cam 25 is in the first position, the outer edge of the cam 25 contacts the second pressing body 23 at a position far from the rotation axis, and the cam 25 applies force to the second pressing body 23, the locking sleeve 21 is deformed and reduced, the locking assembly 2 is in a locked state, and the terminal 3 is locked on the locking section 11 of the conductive rod 1. When the cam 25 is in the second position, the outer edge of the cam 25 contacts the second pressing body 23 at a position close to the rotation axis, and the cam 25 does not apply force to the second pressing body 23 or applies a small force, the locking sleeve 21 returns to a natural state, the locking assembly 2 is in an unlocked state, and the terminal 3 is unlocked from the locking section 11 of the conductive rod 1. That is, the design of the cam 25 used in this application can realize the safe self-locking and unlocking functions of the locking assembly 2, and the terminal 3 only needs to simply rotate the cam 25 when disassembling. Compared with the prior art method of locking the terminal 3 with a nut or bolt, when disassembling the terminal 3, a tool is needed to twist the nut or bolt. The cam 25 design of the present application makes the disassembly and assembly of the terminal 3 more convenient, more efficient, and more adaptable to occasions with limited working space. The second pressing body 23 is configured with an avoidance gap, and the extension portion 24 passes through the avoidance gap.

[0049] See also Figure 6 and Fig.13 As shown, the cam 25 has a flat surface 6 on its outer peripheral side surface. When the cam 25 is in the first position, the flat surface 6 abuts against the second pressing body 23 .

[0050] In this technical solution, when the cam 25 is in the first position, since the plane 6 on the outer side of the cam 25 abuts against the second pressing body 23, the cam 25 can more stably maintain itself in the first position, and the locking assembly 2 can more stably maintain itself in the locked state, that is, the plane 6 designed on the outer side of the cam 25 realizes the stability of the locking assembly 2 in the locked state.

[0051] See also Figure 5As shown, an operating rod 26 is connected to the cam 25. Since the cam 25 is relatively small, it is not convenient or hard to directly rotate the cam 25 by hand. After the operating rod 26 is arranged on the cam 25, the cam 25 can be rotated by simply turning the operating rod 26. More importantly, the operating rod 26 prolongs the torque. By applying a small force on the operating rod 26, the cam 25 can obtain a larger rotational force, thereby making it easier for the cam 25 to switch between the first position and the second position. It should be noted that the cam 25 is constructed with a blind hole, such as Figure 6 As shown by the dotted line, the operating rod 26 is inserted into the blind hole.

[0052] See also Figure 6 and Fig.13 As shown, the cam 25 is an eccentric wheel, a pin shaft 27 is provided on the extension portion 24, the eccentric wheel is rotatably mounted on the pin shaft 27, and the center line of the eccentric wheel does not coincide with the center line of the pin shaft 27.

[0053] In this technical solution, when the cam 25 adopts an eccentric wheel design, its processing and manufacturing is easier, because the outer contour of the eccentric wheel is a regular circle, and the effect equivalent to the cam 25 can be achieved by simply making the center line of the eccentric wheel and the center line of the pin 27 not coincident. Among them, the cam 25, the pin 27 and the operating rod 26 are all made of wear-resistant, corrosion-resistant and high-hardness materials, such as SUS304, 40Cr, alumina ceramics, etc.

[0054] The self-locking principle of the eccentric wheel is introduced as follows:

[0055] When the eccentric wheel is in the first position, Fig.13 As shown, the plane 6 of the eccentric wheel abuts against the workpiece, the position of the workpiece is lowered, the distance between the workpiece and the preset component is b', the line between the center O' of the eccentric wheel and the center O' of the pin 27 is perpendicular to the plane 6, the foot of the perpendicular is point a, the distance between O' and the workpiece is h0, and the distance between O' and the workpiece is h'. When the eccentric wheel is in the second position, as shown in FIG. Fig.13As shown, the outer arc surface of the eccentric wheel contacts the second pressing body 23 and forms a contact point c, the workpiece returns to the initial position, the distance between the workpiece and the preset component is b, b>b', the center O' of the eccentric wheel, the center O" of the pin 27 and point c are not on the same straight line, the angle formed by the line connecting O' and c and the line connecting O" and c is β, β>0, the distance between O' and the workpiece is still h0, and the distance between O" and the workpiece is reduced to h. When the eccentric wheel is in the second position, the eccentric wheel applies an oblique pressure F to the workpiece, F is vertical The component force in the vertical direction is Fy=F·cosβ<F, and the component force in the horizontal direction is Fx=F·sinβ>0. Usually, the friction force of the eccentric wheel is not enough to offset Fx, so the eccentric wheel does not have a locking effect on the workpiece. When the eccentric wheel is in the first position, since O′, O″ and a are on the same straight line, and the line connecting the three points O′, O″ and a is perpendicular to the plane 6, the eccentric wheel exerts a vertical pressure F on the workpiece. The component force Fy in the vertical direction is F·cosβ=F, and the component force Fx in the horizontal direction is F·sinβ=0, such as Fig.14 As shown, at this time, the force applied by the eccentric wheel to the workpiece is the largest, so the locking force of the eccentric wheel is the largest. In addition, the plane 6 at the bottom of the eccentric wheel simultaneously increases the friction between the eccentric wheel and the workpiece, and the locking effect will be more ideal.

[0056] As a specific implementation, the plane 6 is formed by cutting the eccentric wheel, the cutting depth is h, the radius of the eccentric wheel is r, and 0.01r≤h≤0.015r.

[0057] In this embodiment, when the cutting depth is small, the plane area formed on the eccentric wheel is small, and the plane 6 cannot well realize that the cam 25 is stably kept in the first position, and thus the locking assembly 2 cannot be stably kept in the locked state; when the cutting depth is large, the distance from the farthest point on the eccentric wheel to the center line of the pin 27 is too small, and when the cam 25 is in the first position, the push force applied to the second pressing body 23 is small, and the locking sleeve 21 cannot be deformed well, so that the terminal 3 cannot be firmly locked on the conductive rod 1. In order to take both aspects into consideration, preferably, 0.01r≤h≤0.015r.

[0058] See also Figure 1 , Figure 5 and Fig.12As shown, the conductive rod 1 further includes a first limiting section 12 connected to the locking section 11, the diameter of the first limiting section 12 is larger than the diameter of the locking section 11, and the locking sleeve 21 has a partial section sleeved on the first limiting section 12. In the locked state, the inner diameter of the locking sleeve 21 is smaller than or equal to the diameter of the first limiting section 12, and in the unlocked state, the inner diameter of the locking sleeve 21 is larger than the diameter of the first limiting section 12. The first limiting section 12 provides a strong support for the assembly of the locking sleeve 21 on the conductive rod 1 without affecting the compression or release of the locking sleeve 21 on the claw 32, and also radially limits the locking sleeve 21 on the conductive rod 1.

[0059] See also Figure 3 As shown, the conductive rod 1 also includes a second limiting segment 13, the locking segment 11, the first limiting segment 12, and the second limiting segment 13 are connected in sequence, the diameter of the second limiting segment 13 is smaller than the diameter of the first limiting segment 12, and a limiting protrusion 28 is provided on the inner surface of the locking sleeve 21. When the locking sleeve 21 is sleeved on the first limiting segment 12, the limiting protrusion 28 abuts against one end of the first limiting segment 12 toward the second limiting segment 13.

[0060] In this technical solution, when the locking sleeve 21 is sleeved on the first limiting section 12, and the limiting protrusion 28 on the inner surface of the locking sleeve 21 abuts against one end of the first limiting section 12 toward the second limiting section 13, it indicates that the locking sleeve 21 is installed in place, that is, the limiting protrusion 28 realizes the axial installation and positioning of the locking sleeve 21 on the conductive rod 1. Preferably, the limiting protrusion 28 is a protrusion surrounding the inner surface of the locking sleeve 21. After the locking sleeve 21 is installed in place, the limiting protrusion 28 is integrally sleeved on the second limiting section 13. Among them, the locking sleeve 21 is made of metal materials with good conductivity, corrosion resistance, good elasticity and high hardness, such as copper alloy, steel, etc.

[0061] See also Figure 7 and Figure 8 As shown, there are multiple claws 32 , which are spaced apart along the circumference of the connecting terminal 3 , and the clamping groove 4 is a groove surrounding the locking section 11 .

[0062] In this embodiment, when the locking sleeve 21 is deformed and reduced, it will compress all the claws 32, so that each claw 32 is engaged with the slot 4 on the conductive rod 1, and the connection terminal 3 is locked on the conductive rod 1 more firmly. When the slot 4 is a groove surrounding the locking section 11, it can be ensured that the claws 32 in different directions can be smoothly engaged with the slot 4. Among them, the circumferential distribution of multiple claws 32 along the connection terminal 3 refers to the circumferential distribution of each claw 32 along the connection part 31. It should be noted that a claw is formed at one end of the claw 32 away from the connection terminal 3, and the engagement of the claw 32 with the slot 4 mainly refers to the claw being engaged in the slot 4. The claw is an arc-shaped protrusion, and its free end is arc-shaped. When the claw is engaged in the slot 4, the arc-shaped free end fits with the bottom of the slot 4, so that the engagement of the claw with the slot 4 is more stable and not easy to fall out.

[0063] It should also be noted that the conductive wiring assembly also includes an insulating sleeve 7, an iron shell 8, a sealing ring 9 and two nuts 10, the conductive rod 1 also includes a transition section 14 and a threaded section 15, the locking section 11, the first limiting section 12, the second limiting section 13, the transition section 14 and the threaded section 15 are connected in sequence, the conductive rod 1 is a solid stepped shaft structure, the insulating sleeve 7 is sleeved on the outer periphery of the transition section 14, the iron shell 8 is sleeved on the outer periphery of the insulating sleeve 7, the iron shell 8, the insulating sleeve 7 and the transition section 14 are tightly matched and fixedly connected without gaps, and can withstand high temperature and high pressure environments, ensuring that the conductive rod 1 and the iron shell 8 are insulated and non-conductive, and do not cause leakage. One end of the iron shell 8 is in the shape of a hexagonal nut, providing an action surface for the disassembly and assembly tool, and the other end of the iron shell 8 has an external thread to facilitate the installation and fixation of the conductive wiring assembly and the box or shell of the electrical equipment. A groove is provided at the connection between the cylindrical part of the iron shell 8 and the nut shape, which is used to accommodate the sealing ring 9. The sealing ring 9 is installed in the groove of the iron shell to ensure the sealing of the connection between the conductive wiring assembly and the box or shell. The two nuts 10 are threadedly connected to the threaded section 15 of the conductive rod 1, and the two nuts 10 are used to lock the wires inside the electrical equipment. The insulating sleeve 7 can be made of resin, alumina porcelain and other materials. The sealing ring 9 is made of rubber material with good elasticity, good temperature resistance and corrosion resistance. The iron shell 8 is made of high-strength, wear-resistant and corrosion-resistant metal materials, such as SUS304, cast iron and the like.

[0064] The present invention further provides an electrical device, comprising the aforementioned conductive wiring assembly. The electrical device of the present invention may be a motor, a transformer, etc.

First, install the conductive wiring assembly on the box of the electrical equipment, with the threaded section 15 inside the electrical equipment and the locking assembly 2 outside the electrical equipment.
