The term "based on" means "based, at least in part, on". The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment".

[0030] The electrical module adopts an up-and-down wiring method, and requires a wiring space to be left between the upper and lower rows during installation, which is not conducive to space saving. In addition, the electrical module is in a long-term vibration environment, and the wires are prone to fall off from the electrical module. Based on this, embodiments of the present disclosure provide an electrical module to at least partially solve the above problems. In the following, embodiments of the present disclosure will be described in combination withFigures 1 to 6 The principles of the present disclosure are described.

[0031] Figure 1 An installation view of the electrical module 100 is shown according to some embodiments of the present disclosure. Figure 2 and Figure 3 A structural view of the electrical module 100 is shown according to some embodiments of the present disclosure. As shown in Figures 1 to 3 The electrical module 100 described herein can be assembled on a mounting carrier 400, as shown. The mounting carrier 400 can comprise a structure such as a cabinet or a support frame of an electrical cabinet, etc. The electrical module 100 comprises a housing 1. The housing 1 comprises a panel portion 11 and a wiring portion 12. The panel portion 11 is disposed opposite to the wiring portion 12. The panel portion 11 is adapted for the passage of an operating member 5, which can be used to switch the state of the electrical module 100. To facilitate the user to drive the operating member 5, the panel portion 11 can be located at the front of the housing 1. Correspondingly, the wiring portion 12 is located at the back of the housing 1. In some embodiments, the operating member 5 can comprise an operating handle. It can be appreciated that the user can drive the operating handle, which can in turn drive the movable contact assembly to move through an intermediate structure, so as to switch the state of the electrical module 100.

[0032] Figure 4 An enlarged view of the A portion of the electrical module 100 is shown. Figure 3 An enlarged view of the A portion of the electrical module 100 is shown. Figure 5 A sectional view of the electrical module 100 taken along the B-B line is shown. Figure 4 A sectional view of the electrical module 100 taken along the B-B line is shown. Figure 6 A structural view of the limiting member 3, the connecting member 200, the operating tool 300 and the conductive member 2 is shown according to some embodiments of the present disclosure. As shown in Figures 3 to 6 The wiring portion 12 comprises a plurality of wiring holes 121. Each of the plurality of wiring holes 121 is adapted for the insertion of a corresponding connecting member 200. The connecting member 200 can comprise a cable or a busbar, etc. With reference to Figures 4 to 6 The electrical module 100 comprises a plurality of conductive members 2. Each of the plurality of conductive members 2 is disposed within the housing 1 adjacent to a corresponding wiring hole 121. Each of the plurality of conductive members 2 is adapted to be electrically connected to a corresponding connecting member 200. In this way, the connecting member 200 can be connected to the main circuit of the electrical module 100 through the corresponding conductive member 2, and the electrical module 100 can be electrically connected to an external power source, a load, and a measuring instrument such as an ammeter and a voltmeter, etc. through the connecting member 200.

[0033] With reference to Figure 4 and Figure 6The electrical module 100 includes a plurality of limit members 3. The plurality of limit members 3 are disposed within the housing 1, and each of the plurality of limit members 3 is adapted to press the corresponding connecting member 200 against the corresponding conductive member 2. In this way, even if the electrical module 100 is installed in a long-term vibration environment such as the locomotive industry, the connecting member 200 is not easily detached from the corresponding terminal hole 121.

[0034] According to embodiments of the present disclosure, the connecting member 200 is inserted into the electrical module 100 via the terminal hole 121 on the terminal portion 12, realizing a back terminal process. Compared with the up-and-down terminal method, it is advantageous to save installation space. In addition, when the electrical module 100 is installed in a long-term vibration environment, the limit member 3 can press the corresponding connecting member 200 against the corresponding conductive member 2, thereby preventing the connecting member 200 from being detached from the corresponding terminal hole 121.

[0035] It should be noted that the terminal method according to embodiments of the present disclosure can be applied to mechanical switches such as circuit breakers and electronic switches such as solid-state switch units. In addition, the terminal method according to embodiments of the present disclosure can also be applied to other various electrical modules 100, and embodiments of the present disclosure do not limit this. For example, in other embodiments, the power supply end of the gateway unit can adopt the terminal method described above.

[0036] To assemble the electrical module 100 on the mounting carrier 400, for example, with reference to Figures 1 to 3 In some embodiments, the housing 1 can also include a pair of mounting portions 13 adapted to be coupled to the mounting carrier 400. The pair of mounting portions 13 can be disposed on the panel portion 11. Specifically, each of the pair of mounting members 4 passes through the corresponding mounting portion 13 and is connected to the mounting carrier 400. In this way, the electrical module 100 can be firmly assembled on the mounting carrier 400. It should be understood that in other embodiments, the electrical module 100 can also be assembled on the mounting carrier 400 in any other suitable connection manner, such as by clamping, etc.

[0037] With continued reference to Figure 2 and Figure 3 Further, the panel portion 11 can include a main body portion 111 and a decorative plate 112. The decorative plate 112 serves a decorative purpose, and the decorative plate 112 can be disposed on a side of the main body portion 111 facing away from the terminal portion 12. The pair of mounting portions 13 can be disposed on the main body portion 111. The operating member 5 can pass through the main body portion 111 and the decorative plate 112.

[0038] To press the corresponding connecting member 200 against the corresponding conductive member 2, for example, in some embodiments, each of the plurality of limit members 3 can include a mounting screw. By tightening the mounting screw, the corresponding connecting member 200 is pressed against the corresponding conductive member 2. With reference to Figures 4 to 6In some embodiments, the plurality of limit members 3 can each be disposed on one side of the corresponding conductive member 2, and the plurality of limit members 3 can include elastic members. The elastic members can include, for example, elastic pieces. With continued reference to Figure 5 In the case where the corresponding connecting member 200 is not inserted into the corresponding wire hole 121, the elastic member is in an initial state. In the process of inserting the corresponding connecting member 200, the corresponding connecting member 200 can drive the elastic member to move away from the corresponding conductive member 2 to deform. With continued reference to Figure 6 In the case where the corresponding connecting member 200 is inserted into the corresponding wire hole 121, the elastic member is in a deformed state, and the elastic member presses the corresponding connecting member 200 against the corresponding conductive member 2.

[0039] It can be understood that, compared to fastening the connecting member 200 by installing a screw, fastening by the elastic member does not require a tightening operation, and is simple to operate, thereby achieving a quick plug-in operation. In addition, in the process of pulling out the corresponding connecting member 200, a loosening operation is also not required.

[0040] With continued reference to Figures 4 to 6 In some embodiments, the elastic member can include a fixed portion 31 and a movable portion 32. The movable portion 32 can be coupled to the fixed portion 31. The fixed portion 31 can be fixedly disposed in the housing 1. The movable portion 32 is movably disposed in the housing 1, and the movable portion 32 is adapted to press the corresponding connecting member 200. In this way, in the process of inserting the corresponding connecting member 200, the corresponding connecting member 200 can drive the movable portion 32 to move away from the corresponding conductive member 2 to deform. In the case where the corresponding connecting member 200 is inserted into the corresponding wire hole 121, the movable portion 32 can press the corresponding connecting member 200 against the corresponding conductive member 2.

[0041] With continued reference to Figures 4 to 6 In some embodiments, the movable portion 32 can include a pressing portion 321. The pressing portion 321 is disposed at an end of the movable portion 32 away from the fixed portion 31. In the case where the corresponding connecting member 200 is not inserted into the corresponding wire hole 121, the pressing portion 321 can be adjacent to or in contact with the corresponding conductive member 2. The pressing portion 321 can be disposed corresponding to the corresponding wire hole 121 of the plurality of wire holes 121. In this way, in the process of inserting the corresponding connecting member 200, the corresponding connecting member 200 can drive the pressing portion 321 to move away from the corresponding conductive member 2. In the case where the corresponding connecting member 200 is inserted into the corresponding wire hole 121, the pressing portion 321 can press the corresponding connecting member 200 against the corresponding conductive member 2.

[0042] With continued reference to Figure 5 and Figure 6In some embodiments, the extension direction X of the pressing portion 321 is arranged at a preset angle with the insertion direction Y of the corresponding connecting member 200 when the corresponding connecting member 200 is inserted into the corresponding wire hole 121. The preset angle can be in a range between 0° and 20°. In this way, if the corresponding connecting member 200 is pulled out, the connecting member 200 will generate a force F on the pressing portion 321 in a direction opposite to the insertion direction Y. The force F can enable the pressing portion 321 to continuously lock the connecting member 200, achieving a self-locking effect, so as to avoid the connecting member 200 from falling out of the corresponding wire hole 121 in a long-term vibration environment.

[0043] It should be noted that the numbers, values, numbers mentioned above and possibly mentioned elsewhere in the present disclosure are all exemplary and are not intended to limit the scope of the present disclosure in any way. Any other appropriate numbers, values, numbers are possible. For example, according to specific application scenarios and requirements, the preset angle between the extension direction X of the pressing portion 321 and the insertion direction Y of the corresponding connecting member 200 can be 10°.

[0044] Continuing to refer to Figures 4 to 6 In some embodiments, the wire portion 12 can further include a plurality of operation holes 122. The plurality of operation holes 122 can each be adjacent to the corresponding wire hole 121, and the plurality of operation holes 122 can each be arranged corresponding to the corresponding movable portion 32. The plurality of operation holes 122 are each adapted for the insertion of an operation tool 300 to drive the corresponding movable portion 32 to move away from the corresponding conductive member 2. The operation tool 300 can for example include a screwdriver. Continuing to refer to Figure 6 In the case where the corresponding connecting member 200 needs to be pulled out, the user can insert the operation tool 300 into the corresponding operation hole 122 and can use the operation tool 300 to lift the corresponding movable portion 32. In this way, the pressing portion 321 can be moved away from the corresponding conductive member 2 to reduce the force for pulling out the connecting member 200, thereby facilitating the pulling out of the connecting member 200 from the corresponding wire hole 121, achieving a quick pulling out operation.

[0045] It should be noted that returning to refer to Figure 2 and Figure 6 , the insertion direction of the operation tool 300 is the same as the insertion direction Y of the connecting member 200. During the insertion of the operation tool 300, the operation tool 300 can lift the corresponding movable portion 32. At the same time, since the mounting member 4 is previously loosened, the operation tool 300 can also drive the electrical module 100 to move along the insertion direction Y of the connecting member 200. It can be understood that during the movement of the electrical module 100 along the insertion direction Y of the connecting member 200, the connecting member 200 is equivalent to being pulled out in a direction opposite to the insertion direction Y of the connecting member 200, so that the connecting member 200 can be more easily pulled out.

[0046] With reference to the foregoing Figures 4 to 6 In some embodiments, the movable part 32 can further comprise a fitting part 322. The fitting part 322 of the movable part 32 is correspondingly arranged with the operation hole 122. The fitting part 322 is suitable to be driven by the corresponding operation tool 300. In this way, when it is necessary to pull out the corresponding connecting piece 200, the user inserts the operation tool 300 into the corresponding operation hole 122 and uses the operation tool 300 to lift the corresponding fitting part 322. The pressing part 321 can move away from the corresponding conductive piece 2 to reduce the pulling force of the connecting piece 200, thereby facilitating the pulling of the connecting piece 200 out of the corresponding wiring hole 121.

[0047] With reference to the foregoing Figure 6 Further, when the corresponding connecting piece 200 is inserted into the corresponding wiring hole 121, the angle between the extension direction of the fitting part 322 and the insertion direction of the corresponding operation tool 300 can be an acute angle. In this way, the operation tool 300 is facilitated to lift the corresponding fitting part 322 and drive the pressing part 321 to move away from the corresponding conductive piece 2.

[0048] With reference to the foregoing Figure 5 In some embodiments, the movable part 32 can further comprise a bending part 323. One end of the bending part 323 can be connected with the fixed part 31. The other end of the bending part 323 can be connected with the fitting part 322. The bending arrangement of the limiting part 3 according to the embodiments of the present disclosure can reduce the occupation of the limiting part 3 to the space in the shell 1.

[0049] With reference to the foregoing Figure 5 Further, the movable part 32 can further comprise a connecting part 324. One end of the connecting part 324 can be connected with the fitting part 322. The other end of the connecting part 324 can be connected with the pressing part 321.

[0050] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical applications, or technical improvements in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
