[0030] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions 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 only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.
[0031] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific implementation methods disclosed below.
[0032] In order to ensure the normal operation of power equipment and the stable operation of the power system, it is usually necessary to perform live operation and maintenance on the current and voltage circuit terminal blocks. In this process, it is often necessary to short-circuit and shunt the current and voltage circuits or to lead one circuit to another circuit to meet the maintenance conditions.
[0033] In the related art, a copper nose is usually used to short-circuit the terminal block. The copper nose usually includes a sleeve and a nose wing, and a fixed through hole is arranged on the surface of the nose wing. The method of using the copper nose is to sleeve the fixed through hole of the nose wing on the terminal of the terminal block, and then use bolts to pass through the fixed through hole on the surface of the nose wing and the through hole on the terminal in sequence to fix the copper nose to the terminal, and then cut off the insulating protective layer of the cable end to expose the conductive cable core, and then insert the conductive cable core into the cable core compartment formed by the inner hole of the sleeve, and then use hydraulic pliers to form an annular groove locally in the sleeve, and further use the contraction of the annular groove to make the sleeve clamp the conductive cable core to obtain a fixed connection.
[0034] However, when using copper noses to short-circuit the terminal block, since the conductive cable core becomes fluffy after removing the insulating protective layer, the inner hole diameter of the sleeve is large, which can easily cause the crimping to be loose, causing the copper nose to loosen or even fall off, making it impossible to short-circuit the terminal block, affecting maintenance.
[0035] The embodiment of the present application provides a terminal block circuit short-circuiting device to solve the technical problem that in the related art, a copper nose is used to short-circuit the terminal block 300. Since the conductive wire core becomes fluffy after the insulating protective layer is removed, the inner hole diameter of the sleeve is relatively large, which can easily cause the crimping to be loose, causing the copper nose to loosen or even fall off, thereby failing to short-circuit the terminal block 300 and affecting maintenance.

[0037] Reference Figure 1 and Figure 2 , the embodiment of the present application provides a terminal block 300 circuit short-circuiting device, including: a connecting assembly 100 and a fixing member 200;
[0038] At least two connection components 100, one side of the connection component 100 is provided with a mating portion, the other side of the connection component 100 is provided with a connecting portion, and two adjacent connection components 100 can be detachably connected through the mating portion and the connecting portion;
[0039] The connection assembly 100 is also provided with a second through hole that is mutually compatible with the first through hole of the connection terminal 310 of the terminal row 300, and the fixing member 200 is used to pass through the first through hole and the second through hole in sequence to fix the connection assembly 100 to the connection terminal 310.
[0040] It should be noted that the terminal block 300 is an insulating component that carries multiple or multiple groups of mutually insulated terminal components and is used to fix the support. The function of the terminal block 300 is to connect the lines of the devices inside the screen and the devices outside the screen, and play the role of signal (current and voltage) transmission. With the terminal block 300, the wiring is beautiful and easy to maintain. When connecting long-distance lines, it is mainly reliable, and the construction and maintenance are convenient.
[0041] For example, the terminal block 300 can be set in different colors according to the external housing 110. For example, red, yellow, and green can be used to distinguish the three phases A, B, and C.
[0042] For another example, the terminal row 300 has a plurality of terminal assemblies, each of which includes a conductive slider 320, a first conductive block 330 and a second conductive block 340, wherein the connecting terminal 310 is respectively arranged on the first conductive block 330 and the second conductive block 340, and the conductive slider 320 is used to slide between the first conductive block 330 and the second conductive block 340 to realize a passage or disconnection of the circuit.
[0043] Exemplarily, the short-circuit device includes a first short-circuit device, a second short-circuit device and a third short-circuit device, the first short-circuit device includes a first connecting component and a first fixing member, the second short-circuit device includes a second connecting component and a second fixing member, and the third short-circuit device includes a third connecting component and a third fixing member. In a specific implementation, the contact end of the first connecting component and the end wall of the first through hole of the first connecting terminal of the terminal row are adapted to each other, and the first fixing member sequentially passes through the first through hole of the first connecting component and the second through hole of the first connecting terminal, thereby electrically connecting the first short-circuit device and the first connecting terminal, and then the second connecting component is connected to the first connecting terminal. After the contact end of the first connection component and the end wall of the first through hole of the second connection terminal of the terminal row are adapted to each other, and the connection part of the first connection component and the matching part of the second connection component are adapted to each other, the contact end of the third connection component and the end wall of the first through hole of the third connection terminal of the terminal row are adapted to each other, and the connection part of the second connection component and the matching part of the third connection component are matched with each other, the third fixing member is sequentially passed through the first through hole of the third connection component and the second through hole of the third connection terminal, so as to electrically connect the third short-circuit device and the third connection terminal, thereby realizing the short circuit of the first connection terminal and the third connection terminal. It should be noted that the first connection terminal, the second connection terminal and the third connection terminal are arranged in parallel, and the second connection terminal is arranged between the first connection terminal and the third connection terminal.
[0044] From the above description, it can be seen that this solution achieves the following technical effects:
[0045] The embodiment of the present application provides a terminal block circuit short-circuiting device, including a connecting component 100 and a fixing component 200, wherein the connecting component 100 is provided with at least two, a mating portion is provided on one side of the connecting component 100, and a connecting portion is provided on the other side of the connecting component 100, and two adjacent connecting components 100 can be detachably connected through the mating portion and the connecting portion, and the current conduction from one connection device to another connection device can be achieved through the connection of the connecting component 100. The embodiment of the present application allows the connecting component 100 to be fixed to the connection terminal 310 by passing the fixing component 200 through the first through hole and the second through hole in sequence, so as to achieve electrical connection between the short-circuiting device and the connection terminal 310 of the terminal block 300, and the short-circuiting device can be firmly fixed to the connection terminal 310. Through the arrangement of the embodiment of the present application, a terminal block 300 circuit short-circuiting device is provided, which is firmly fixed, can achieve short-circuiting between the connection terminals 310 of the terminal block 300, is detachable, has high flexibility, and is easy to use.
[0046] Figure 3 yes Figure 2 A schematic diagram of the structure of the medium and short-circuit device; Figure 4 yes Figure 3 A top view of Figure 5 yes Figure 2 A top view of Figure 6yes Figure 5 Sectional view of AA.
[0047] In some examples, reference Figures 3 to 6 , the connection assembly 100 includes a housing 110 and a conductive component 120;
[0048] The conductive component 120 is provided with a matching portion and a connecting portion. The shell 110 is provided to cover the outside of the conductive component 120. The shell 110 is provided as an insulating component, and the conductive component 120 is provided as a metal component.
[0049] For example, the housing 110 may be a plastic part, and the conductive part may be a metal part such as copper.
[0050] In the embodiment of the present application, the shell 110 is provided, and the shell 110 is covered on the outside of the conductive component 120. On the one hand, it can prevent the conductive component 120 from being damaged and protect the conductive component 120. On the other hand, the shell 110 is provided as an insulating member. When the connecting terminal 310 of the terminal row 300 is short-circuited by the short-circuiting device, it can insulate the conductive component 120 and prevent the operator from directly contacting the conductive component 120, thereby protecting the operator.
[0051] Exemplarily, the conductive component 120 includes a connecting member 121 and a telescopic member 122;
[0052] The matching portion and the connecting portion are arranged on the connecting member 121, the connecting member 121 is provided with a third through hole, the telescopic member 122 is provided with a first through hole, the first through hole and the third through hole are arranged coaxially, the contact end of the connecting member 121 abuts against the end wall of the first through hole, and the telescopic member 122 is movably arranged in the third through hole, so that the telescopic member 122 has a first position where it is completely covered outside the fixing member 200 and a second position where at least part of the fixing member 200 is exposed;
[0053] The housing 110 is disposed outside the connecting member 121 .
[0054] In a specific implementation, when one of the conductive components 120 is connected to a terminal of the terminal block 300, the embodiment of the present application enables the telescopic member 122 to have a first position completely covering the outside of the fixing member 200, thereby preventing the other fixing member 200 from being accidentally inserted into the connecting terminal 310 that needs to be short-circuited, causing the short-circuiting device to become conductive, thereby preventing the operator from accidentally operating the fixing member 200 in and out.
[0055] The implementation of the present application enables the telescopic member 122 to have a first position in which the telescopic member 122 is completely covered outside the fixing member 200 and a second position in which the fixing member 200 is at least partially exposed. This can prevent the fixing member 200 from being accidentally inserted into the connecting terminal 310, causing the short-circuit device to become conductive. This can prevent staff from accidentally operating the fixing member 200, thereby improving the safety performance of the short-circuit device.
[0056] Exemplarily, a spring is disposed on the outer side wall of the telescopic member 122 .
[0057] In the embodiment of the present application, a spring is arranged on the outer wall of the telescopic member 122. Before the operator operates the fixing member 200, under the elastic action of the spring, the telescopic member 122 is in the first position where it can completely cover the fixing member 200. When the staff needs to operate the fixing member 200, the contact end of the connecting member 121 is pressed against the end wall of the connecting terminal 310 of the terminal row 300. The staff applies a downward force to the telescopic member 122, so that the telescopic member 122 is in the second position, thereby facilitating the fixing member 200 to pass through the first through hole and the second through hole in sequence to fix the connecting assembly 100 to the connecting terminal 310.
[0058] In some other examples, the housing 110 is formed with a first groove that is adapted to the connecting member 121, the first groove includes a top wall and a first side wall and a second side wall that are arranged opposite to the top wall, and a connecting channel is formed between the first side wall and the second side wall;
[0059] The connecting member 121 is disposed in the first groove, and the matching portion and the connecting portion are both disposed in the connecting channel.
[0060] The embodiment of the present application can limit the connector 121 within the first groove by setting the first groove. The embodiment of the present application can, on the one hand, provide protection and insulation for the connector 121 by setting the top wall, the first side wall and the second side wall. On the other hand, it can limit the connector 121. Moreover, by forming a connecting channel between the first side wall and the second side wall, space can be reserved for the matching of the matching part and the connecting part, thereby facilitating the mutual adaptation of the matching part and the connecting part.
[0061] Exemplarily, the connecting portion is provided with a second groove 121 a, and the matching portion is provided with a protrusion 121 b which is adapted to the second groove 121 a.
[0062] For example, the first groove is provided with a matching protrusion 121b, and the side wall of the protrusion 121b is provided with a matching groove that matches with the matching protrusion 121b.
[0063] The embodiment of the present application realizes a detachable connection between two adjacent connection components 100 through the mutual adaptation of the second groove 121a and the protrusion 121b, and when the two connection components 100 are connected, electrical conduction between the connection components 100 can be realized at the same time.
[0064] For example, the fixing member 200 is configured as a tightening bolt, the tightening bolt is configured as a metal member, and the outer wall of the tightening bolt is provided with a thread that is mutually compatible with the inner wall of the first through hole and the inner wall of the second through hole.
[0065] The embodiment of the present application sets a tightening bolt, and sets the tightening bolt as a metal part, so that an electrical connection can be made between the tightening bolt and the connecting terminal 310, and then electrical conduction is performed through the connecting assembly 100, thereby realizing short-circuiting of the connecting terminal 310 in the terminal row 300.
[0066] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
