Description

Technical Field

[0001] The present invention belongs to the technical field of electrification equipment, and in particular relates to an electrical device. Background Art

[0002] Electrical connection components are important components of electrical equipment. Among them, the components used to achieve high-voltage electrical connection are mainly conductive bars, which can connect battery modules, high-voltage devices, connectors and other components to form series and parallel connections of high-voltage systems and achieve current transmission.

[0003] The existing conductive bar is generally fixed on the device housing, one end is connected to the external terminal block, and the other end is connected to the circuit board inside the device through a cable. This connection method has the following defects: First, it is difficult for the cable to form a reliable spatial connection relationship between the conductive bar and the circuit board. If the device vibrates (for example, electrical equipment placed outdoors is disturbed by the external environment and vibrates), it may cause the conductive bar or the circuit board to deviate from the established installation position, resulting in unnecessary positional displacement between the two. This positional displacement may cause the internal connection cable to be pulled, causing the cable to deform or break, and ultimately causing the conductive connection between the conductive bar and the circuit board to fail, resulting in poor reliability. Second, this connection method of connecting the conductive bar and the internal circuit board through a cable is complicated to operate, and requires multi-point installation. At the same time, it is also necessary to avoid interference between the cable and the components on the circuit board, which easily leads to complex installation operations and low efficiency. Third, during installation, the circuit board and the conductive bar must be installed on the device body separately, which will also lead to complex installation operations and low efficiency. In addition, the numerous internal cables also make the internal aesthetics of the device poor and make it more difficult to manage the cables. Summary of the invention

The main partition without the front detachable plate installed can extend into the parallel gap between two adjacent circuit board overlapping holes in the second conductive row.

[0010] In some embodiments, the first conductive bar and the positioning platform are connected in a detachable manner, as well as the second conductive bar and the positioning platform.

[0011] In some embodiments, the partition includes a main partition disposed on both sides of the positioning platform and a rear detachable plate detachably connected to the rear side of the main partition, and the rear detachable plate is overlapped and fixed to the board surface of the circuit board; After removing the rear removable plate, the circuit board overlapping hole extends backward out of the wiring isolation space, and the electrical equipment also includes a transition conductive bar, one end of which is overlapped and fixed to the terminal by a fastener, and the other end of the transition conductive bar is connected to the circuit board overlapping hole extending out of the wiring isolation space by a fastener.

[0012] In some embodiments, the electrical device further includes a mounting bracket, which extends along a path perpendicular to the front-rear direction to surround the outer periphery of the fixed bracket, supports the fixed bracket, and is fixedly connected to the device housing.

[0023] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0024] Please also read Figures 1 to 17 , the electrical device provided by the present invention is now described. The electrical device comprises a circuit board 1, a main conductive bar 2 and a fixing bracket 3; a terminal 4 is fixed on the board surface of the circuit board 1; a circuit board lap hole 201 is formed at the rear end of the main conductive bar 2, and a terminal wiring hole 202 is formed at the front end, and the main conductive bar 2 is fixedly connected to the terminal 4 through a fastener 5 penetrating the circuit board lap hole 201; the fixing bracket 3 is formed with a wiring isolation space 301, the main conductive bar 2 is fixed in the wiring isolation space 301, the fixing bracket 3 is fixed on the board surface of the circuit board 1 by lap connection, and the terminal 4 and the fixing bracket 3 jointly form a support between the main conductive bar 2 and the circuit board 1.

[0025] In this embodiment, the fixing bracket 3 mainly supports and fixes the main conductive bar 2. In order to avoid affecting the electrical connection between the circuit board 1 and the main conductive bar 2, the fixing bracket 3 is preferably made of insulating material. The material of the fixing bracket 3 can be glass fiber reinforced plastic, high-density polyethylene, high-strength epoxy resin composite material, etc., which is not limited here. The fixing bracket 3 can be formed by integral injection molding. In addition, the implementation of the main conductive bar 2 includes but is not limited to copper bars.

[0026] In this embodiment, the external connection terminal 8 is attached to the front of the main conductive bar 2 , and the connection between the two is achieved by a fastener 5 (generally a threaded fastener) penetrating the connection terminal 8 and the terminal connection hole 202 .

[0027] Compared with the prior art, the electrical device provided in this embodiment has the following beneficial effects: 1) The terminal 4 is directly fixed on the board surface of the circuit board 1, and the extension direction of the terminal 4 is perpendicular to the board surface. The circuit board overlap hole 201 at the rear end of the main conductive bar 2 is aligned with the terminal 4, and the main conductive bar 2 is connected to the terminal 4 through the fastener 5 (generally a threaded fastener), and the terminal connection hole 202 at the front end of the main conductive bar 2 is connected to the external cable. The terminal 4 is connected between the main conductive bar 2 and the circuit board 1 to form a hard connection between the main conductive bar 2 and the circuit board 1. On the one hand, the connection cable and related operations between the main conductive bar 2 and the circuit board 1 are eliminated, the installation process is simplified, and the problem of numerous internal cables and complex wiring is avoided. The electrical connection structure between the main conductive bar 2 and the circuit board 1 will not affect the arrangement of other components on the circuit board 1, and the internal electrical connection structure of the equipment is simpler and more beautiful; on the other hand, the hard connection between the circuit board 1 and the main conductive bar 2 also enhances the bonding strength between the two, has stronger anti-seismic ability, and is not prone to connection failure.

[0028] 2) The fixing bracket 3 provides a wiring isolation space 301 for the main conductive bar 2. Since the fixing bracket 3 is fixed to the main conductive bar 2 and the circuit board 1, the main conductive bar 2, the circuit board 1 and the fixing bracket 3 can form an integral structure, which can be pre-assembled and then installed as a whole into the device housing 6 to form a modular installation method. Compared with the traditional method of fixing the circuit board 1 and the main conductive bar 2 on the housing one by one and then electrically connecting the two, the modular installation method of this embodiment can obviously achieve higher installation efficiency.

[0029] 3) The main conductive bar 2 and the circuit board 1 are supported by the terminal 4. Since the terminal 4 is generally set at the edge of the circuit board 1 and the thickness of the circuit board 1 is relatively small, if the terminal 4 is only set between the main conductive bar 2 and the circuit board 1, there is a problem of insufficient supporting force provided by the terminal 4. During the assembly process using the fastener 5, and during the process of moving the main conductive bar 2 and the circuit board 1 after assembly, the circuit board 1 may crack. In the present application, while the terminal 4 is set, the fixing bracket 3 is overlapped and fixed to the circuit board 1 to form another support between the main conductive bar 2 and the circuit board 1, effectively avoiding the problem of deformation and cracking of the circuit board 1 in the area where the terminal 4 is located due to the shaking of the main conductive bar 2, and the assembly difficulty is lower and the reliability of use is higher.

[0030] In some embodiments, see Figure 1 The electrical device also includes a device housing 6, and a mounting opening 601 is provided on the device housing 6. The circuit board 1 is placed in the device housing 6. The fixed bracket 3 and the main conductive bar 2 both pass through the mounting opening 601. The mounting opening 601 supports the fixed bracket 3 to limit the displacement of the fixed bracket 3 in the vertical direction. In this embodiment, the setting mode of the fixed bracket 3 passing through the mounting opening 601 realizes the supporting effect of the mounting opening 601 on the fixed bracket 3. If the board surface of the circuit board 1 is perpendicular to the vertical direction, the mounting opening 601 can effectively avoid the tendency of the fixed bracket 3 to fall downward, and avoid the problem that the fixed bracket 3 is suspended in the air and the circuit board 1 is deformed by pressure or tension; if the board surface of the circuit board 1 is parallel to the vertical direction, the mounting opening 601 avoids the tendency of the fixed bracket 3 to fall downward, and thus avoids the problem that the main conductive bar 2 is driven to swing downward by the falling of the circuit board 1, and finally causes the connection between the terminal 4 and the circuit board 1 to fail due to the twisting force or the circuit board 1 is damaged, further improving the stability of the connection between the circuit board 1 and the main conductive bar 2 and the reliability of use.

[0031] In some embodiments, the conductive bar and the wiring isolation space 301 are adapted to each other. Fig.13The rear end of the main conductive bar 2 extends backward out of the wiring isolation space 301, and the circuit board overlapping hole 201 is located outside the wiring isolation space 301. The electrical equipment also includes a transition conductive bar 7, one end of the transition conductive bar 7 is overlapped and fixed to the terminal 4 by a fastener 5, and the other end of the transition conductive bar 7 is connected to the circuit board overlapping hole 201 by the fastener 5. In this embodiment, the size of the fixing bracket 3 is shortened in the front-to-back direction, the overlapping contact area between the fixing bracket 3 and the circuit board 1 is reduced, and the rear end of the conductive bar is exposed outside the fixing bracket 3. A transition connection is formed between the main conductive bar 2 and the terminal 4 by setting the transition conductive bar 7. The position between the main conductive bar 2 and the terminal 4 may not be directly opposite to each other front to back. On the one hand, the position setting of the terminal 4 can be more flexible and more suitable for the layout of other components on the circuit board 1; on the other hand, by flexibly selecting the transition conductive bar 7, the same set of fixing brackets 3 and conductive bars can adapt to the installation of circuit boards 1 of different models, and the use cost can also be reduced; on the other hand, due to the shortening of the front-to-back size of the fixing bracket 3, the space occupied by the fixing bracket 3 on the periphery of the circuit board 1 can be reduced, which is conducive to the compact design inside the electrical equipment.

[0032] In some other embodiments, the conductive bar and the wiring isolation space 301 are adapted to each other. Figure 5 The main conductive bar 2 is located as a whole in the wiring isolation space 301 and is isolated and protected by the fixing bracket 3 to avoid interference with other components on the circuit board 1. This can greatly shorten the safety distance around the main conductive bar 2 and further improve the compact design requirements.

[0033] In some embodiments, see Figures 4 to 17 In order to form effective isolation protection for the conductive bar, the fixed bracket 3 includes a positioning platform 310 and a partition 320 arranged on both sides of the positioning platform 310, and a wiring isolation space 301 is formed between the partitions 320 on both sides. Based on this, in order to realize the connection between the conductive bar and the terminal 4, the partition 320 protrudes backward from the positioning platform 310, and forms a connection avoidance space 302 on the rear side of the positioning platform 310. The main conductive bar 2 is connected and fixed to the table of the positioning platform 310, and the circuit board overlap hole 201 is located in the connection avoidance space 302, and the terminal 4 is also located in the connection avoidance space 302 during assembly, which is convenient for the main conductive bar 2 to connect with the terminal 4; at the same time, in order to realize effective auxiliary support between the main conductive bar 2 and the terminal 4, the partition 320 is overlapped and fixed to the board surface of the circuit board 1. Optionally, the partition 320 protrudes from the table of the positioning platform 310 to cover the main conductive bar 2 in a direction perpendicular to the table of the positioning platform 310.

[0034] Based on the above embodiments, see Figures 4 to 17The main conductive bar 2 includes a first conductive bar 210 and a second conductive bar 220; in the first conductive bar 210, the circuit board overlap hole 201 is penetrated in the up-down direction, and the penetration direction of the terminal wiring hole 202 is set at an angle with the penetration direction of the circuit board overlap hole 201; the second conductive bar 220 has a plurality of circuit board overlap holes 201 connected in parallel with each other and a terminal wiring hole 202 arranged at a parallel node, and the circuit board overlap holes 201 in the second conductive bar 220 are penetrated in the up-down direction; the partition 320 includes a main partition 321 and a front detachable plate 322 detachably connected to the front side of the main partition 321, and the main partition 321 without the front detachable plate 322 installed can extend into the parallel gap between two adjacent circuit board overlap holes 201 in the second conductive bar 220. Among them, in order to adapt to the installation of the second conductive bar 220, the fixed bracket 3 needs to set at least two wiring isolation spaces 301 side by side, that is, the fixed bracket 3 has at least two positioning platforms 310 and at least three partitions 320, and the brother circuit board overlap hole 201 corresponds to the wiring isolation space 301 one by one; it should be noted that in order to make the structure simpler, only one partition 320 can be set between two adjacent positioning platforms 310 for isolation. This embodiment can selectively adopt the first conductive bar 210 and the second conductive bar 220 according to actual use requirements to achieve series connection or parallel connection with the external wiring terminal 8, and has greater flexibility in use. The first conductive bar 210 and the second conductive bar 220 can be used alone or in combination. In addition, when the second conductive bar 220 is needed, the front removable plate 322 is removed, and the second conductive bar 220 does not need to be set too long, which can reduce the amount of conductive material used and improve the compactness of the structure.

[0035] Examples of detachable connection methods between the main partition 321 and the front detachable plate 322 are as follows: 1) The main partition 321 and the front detachable plate 322 are integrally connected via a plastic transition zone. Since the hardness of the plastic transition zone is relatively low, the front detachable plate 322 can be cut off by cutting with tools; wherein, the materials of the main partition 321, the front detachable plate 322 and the plastic transition zone can be the same or different, and the materials of the main partition 321 and the front detachable plate 322 can be the same or different. 2) A weakened zone is formed between the main partition 321 and the front detachable plate 322. Since the strength of the weakened zone is relatively low, it can be directly broken by applying force to separate the front detachable plate 322 from the main partition 321. The specific implementation method of the weakened zone includes but is not limited to an easy-to-break groove 323 extending in the up and down directions (such as Figures 1 to 9As shown), multiple through holes distributed in the up-and-down direction, etc. 3) The main partition 321 and the front removable plate 322 are bonded by an adhesive layer. The adhesive layer can be broken by directly pulling the front removable plate 322, and the front removable plate 322 can be removed. 4) One of the main partition 321 and the front removable plate 322 is provided with a buckle, and the other of the main partition 321 and the front removable plate 322 is provided with a bayonet, and loading and unloading are achieved by front-to-back clamping, wherein the buckle and the bayonet are respectively located on the docking side of the main partition 321 and the front removable plate 322. 5) One of the main partition 321 and the front removable plate 322 is provided with a plug-in column extending forward and backward, and the other of the main partition 321 and the front removable plate 322 is provided with a socket, and loading and unloading are achieved by front-to-back plug-in, wherein the plug-in column and the socket are respectively located on the docking side of the main partition 321 and the front removable plate 322. 6) One of the main partition plate 321 and the front removable plate 322 is provided with a plug-in groove extending vertically, and the other of the main partition plate 321 and the front removable plate 322 is correspondingly provided with an insertion strip extending vertically, and the loading and unloading of the two are realized by plugging them up and down, wherein the insertion strip and the plug-in groove are respectively located on the docking side of the main partition plate 321 and the front removable plate 322.

[0036] In some specific embodiments of the first conductive row 210, see Figure 5 The first conductive bar 210 has a first rear connecting plate 211 and a first front connecting plate 212. The middle part of the first rear connecting plate 211 is fitted and connected to the table surface of the positioning table 310; the first front connecting plate 212 is connected to the front edge of the first rear connecting plate 211 and is arranged at an angle to the first rear connecting plate 211. The first front connecting plate 212 is located as a whole within the wiring isolation space 301; the rear part of the first rear connecting plate 211 forms a circuit board overlapping hole 201, the front part forms a first terminal wiring hole 2021, and the first front connecting plate 212 is formed with a second terminal wiring hole 2022. Before connecting with the circuit board 1, each first conductive row 210 is placed in the corresponding wiring isolation space 301, and the first rear connection plate 211 is connected and fixed to the positioning platform 310. Then, the first conductive row 210 is overlapped and fixed to the terminal 4 by the fastener 5 passing through the first circuit board overlap hole 201, and the terminal 8 is connected and fixed to the first terminal wiring hole 2021 or the second terminal wiring hole 2022 by the fastener 5, so as to finally realize the conductive connection assembly.

[0037] In this embodiment, the terminal block 8 includes a connecting plate 810 and a connecting section 820. The connecting plate 810 is provided with a terminal through hole, and the terminal through hole can be connected to the first terminal wiring hole 2021 or the second terminal wiring hole 2022 through a fastener 5. The connecting section 820 is cylindrical and is fixed to the end of the wire 12 by a covering and fastening method. Based on this, the terminal block 8 is divided into two categories: the first category, the plate surface of the connecting plate 810 is parallel to the central axis of the connecting section 820 (such as Figure 2As shown), this type of terminal 8 is connected to the first conductive bar 210 up and down, that is, the connecting plate 810 is attached to the upper plate surface of the first rear connecting plate 211, and the first terminal wiring hole 2021 is connected to the terminal via hole correspondingly; the second type, the plate surface of the connecting plate 810 is set at an angle with the central axis of the connecting section 820 (for example, an angle of 80°, 85°, 90°), as shown Figure 3 As shown, such a connection terminal 8 is connected to the first conductive bar 210 front to back, that is, the connection plate 810 is attached to the front plate surface of the first front connection plate 212, and the second terminal connection hole 2022 is connected to the terminal via hole. In this way, the connection method of the connection terminal 8 and the first conductive bar 210 can better adapt to the extension direction of the wire 12 and avoid conductive bending. It should be noted that in order to better achieve wiring, the angle between the first front connection plate 212 and the first rear connection plate 211 is the same as the angle between the connection plate 810 and the central axis of the connection section 820. The figure exemplarily shows an embodiment in which both angles are 90°.

[0038] In this embodiment, the first front connecting plate 212 is located in front of the positioning platform 310, and there is a certain distance between it and the positioning platform 310 to avoid the fastener 5 between the wiring terminal 8 and the first front connecting plate 212 (such as Figure 8 Specifically, in order to achieve the front and rear limit between the positioning platform 310 and the first front connecting plate 212, a limit platform 313 is further protruded forward at the front lower part of the positioning platform 310. The limit platform 313 can abut against the rear plate surface of the first front connecting plate 212 to limit the displacement of the first conductive bar 210 in the front and rear directions. Alternatively, the first front connecting plate 21202 is located in front of the positioning platform 310, and it fits with the positioning platform 310. In order to achieve the connection between the first front connecting plate 212 and the connecting terminal 8, a avoidance hole 303 corresponding to the second terminal wiring hole 2022 is provided on the front side of the positioning platform 310 (as shown in FIG. Fig.15 and Fig.16 as shown).

[0039] In order to prevent the wire 12 from being bent and damaged during the process of being led out, the wire 12 is led out in a forward direction. Therefore, in order to avoid the problem of the wire 12 being bent, in the first embodiment, see Fig.10A first foolproof bracket 340 is provided in the wiring isolation space 301. The first foolproof bracket 340 is located above the first rear connection plate 211. The first terminal wiring hole 2021 is located in front of the first foolproof bracket 340. The first foolproof bracket 340 can abut against the rear side of the connecting section 820 in the wiring terminal 8 to limit the installation posture of the wiring terminal 8. This embodiment is mainly used for the installation of the first type of wiring terminal 8 mentioned above. The wiring terminal 8 is connected to the first terminal wiring hole 2021. The wire 12 can be led forward without bending. The first foolproof bracket 340 prevents the second type of wiring terminal 8 from being connected to the first terminal wiring hole 2021.

[0040] In order to avoid the problem of bending of the wire 12, in the second embodiment, see Fig.10 , a second foolproof bracket 350 is provided in the wiring isolation space 301, the first foolproof bracket 340 is located in front of the first front connecting plate 212, the second terminal wiring hole 2022 is located above the second foolproof bracket 350, and the second foolproof bracket 350 can abut against the lower side of the connecting section 820 in the wiring terminal 8 to limit the installation posture of the wiring terminal 8. This embodiment is mainly used for the installation of the aforementioned second type of wiring terminal 8, the wiring terminal 8 is connected to the second terminal wiring hole 2022, the wire 12 can be led out forward without bending, and the second foolproof bracket 350 is used to prevent the first type of wiring terminal 8 from being connected to the second terminal wiring hole 2022.

[0041] It should be noted that the first embodiment and the second embodiment described above can be used alone or in combination, and this embodiment exemplarily shows the combined use.

[0042] On the basis that the first conductive bar 210 has the first rear connection plate 211 and the first front connection plate 212, in order to facilitate connection with the wiring terminal 8, the front of the fixing bracket 3 and the main conductive bar 2 are exposed outside the device housing 6. According to its wiring conditions, the lower part of the fixing bracket 3 needs to meet a certain safety distance to avoid contact with the peripheral modules or other main conductive bars 2. Therefore, in some embodiments, see Figures 10 to 12 , Figures 15 to 17 A stepped boss 360 is protruded from the lower side of the front portion of the partition 320, and the lower edge of the stepped boss 360 protrudes downward from the lower end of the first front connecting plate 212. The first front connecting plate 212 is within the protection range of the stepped boss 360, which meets the safety requirements of the lower portion of the main conductive bar 2. At the same time, it also prevents the fixing bracket 3 from protruding upward too much from the circuit board 1 as a whole, affecting the compactness of the structure in the up and down directions.

[0043] In other embodiments that meet safety requirements, see Figure 2A closing member 370 (such as a sealing plate) is provided at the lower portion of two adjacent partitions 320. The rear edge of the closing member 370 extends to the positioning platform 310. The closing member 370 is located below the first front connecting plate 212, forming a closed design below the first front connecting plate 212, thereby playing a role of isolation and protection.

[0044] In some specific embodiments of the second conductive bar 220, see Figure 5 The second conductive bar 220 has a plurality of second rear connection plates 221 and a second front connection plate 222, and the front edges of the plurality of second rear connection plates 221 are respectively connected to the second front connection plates 222 at intervals along the left-right direction; the plate surface of the second rear connection plates 221 is perpendicular to the up-down direction, and each second rear connection plate 221 is respectively placed in a different wiring isolation space 301, and is detachably connected to the positioning platform 310 in the corresponding wiring isolation space 301; a circuit board overlap hole 201 is formed at the rear of the second rear connection plate 221, and a terminal wiring hole 202 is formed on the second front connection plate 222.

[0045] The layout of the second rear connecting plate 221 and the second front connecting plate 222 is exemplified as follows: 1) The second front connecting plate 222 and the second rear connecting plate 221 are parallel to each other, wherein the second front connecting plate 222 and the second rear connecting plate 221 can be flush with each other (e.g. Figures 5 to 7 2) The second front connecting plate 222 is arranged at an angle (e.g., an angle of 80°, 85°, or 90°) with the second rear connecting plate 221, and only one third terminal wiring hole 202 is arranged on the second front connecting plate 222, which is suitable for connecting and adapting with the terminal 8 from front to back.

[0046] More specifically, the left-right width of the second front connecting plate 222 gradually increases in a direction approaching the second rear connecting plate 221 , and the side edges of the two second rear connecting plates 221 at both ends are flush with the corresponding side edges of the second front connecting plate 222 .

[0047] More specifically, in order to improve the versatility of parts, the structure of the second conductive row 220 can be modified on the basis of the first conductive row 210. For example, an auxiliary connecting row 9 is provided, and the front side of the auxiliary connecting row 9 forms a second front connecting plate 222, and the rear side forms a plurality of auxiliary connecting plates 910 extending downward, each auxiliary connecting plate 910 is respectively fitted and connected to a different first front connecting plate 212 (specifically, through connection with the second terminal wiring hole 2022). In this case, the first rear connecting plate 211 is the second rear connecting plate 221.

[0048] In some specific embodiments, the first conductive bar 210 and the positioning platform 310, as well as the second conductive bar 220 and the positioning platform 310, are all detachably connected, so that different types of main conductive bars 2 can be more conveniently replaced according to usage requirements, and the usage flexibility is greater. In this embodiment, the detachable connection between the positioning platform 310 and the main conductive bar 2 includes, but is not limited to, connection through threaded fasteners, clamping, plugging, etc. Figure 1 , Figure 5 and Figure 6 The embodiment of the connection through threaded fasteners is shown in the figure as an example, specifically: a plate through hole is provided in the middle of the main conductive bar 2, a table hole is correspondingly provided on the upper surface of the positioning table 310, and the plate through hole and the table hole are connected by a fastener 5.

[0049] In some embodiments, see Fig.13 and Fig.14 The partition 320 includes a main partition 321 disposed on both sides of the positioning platform 310 and a rear detachable plate 324 detachably connected to the rear side of the main partition 321. The rear detachable plate 324 is overlapped and fixed to the board surface of the circuit board 1; after the rear detachable plate 324 is removed, the circuit board overlap hole 201 extends backward to the wiring isolation space 301. The electrical equipment also includes a transition conductive bar 7. One end of the transition conductive bar 7 is overlapped and fixed to the terminal 4 through a fastener 5, and the other end of the transition conductive bar 7 is connected to the circuit board overlap hole 201 extending out of the wiring isolation space 301 through the fastener 5. In this embodiment, the partition 320 is functionally divided. If the rear detachable plate 324 is not removed, the main conductive bar 2 is completely placed in the wiring isolation space 301, and the transition conductive bar 7 is not needed at this time; if the rear detachable plate 324 is removed, the rear end of the main conductive bar 2 is exposed outside the wiring isolation space 301, and the transition conductive bar 7 can be used at this time, which is more flexible to use. The connection method between the rear detachable plate 324 and the main partition plate 321 is similar to that of the aforementioned front detachable plate, and will not be listed here one by one.

[0050] In some embodiments, see Fig.10 and Fig.11 The electrical device further includes a mounting bracket 10, which extends along a path perpendicular to the front-rear direction to surround the outer periphery of the fixed bracket 3. The mounting bracket 10 supports the fixed bracket 3 and is fixedly connected to the device housing 6. In this embodiment, the fixed bracket 3 is fixed to the device housing 6 by the mounting bracket 10, and the position of the fixed bracket 3 is more stable, which can reduce the force of the fixed bracket 3 on the circuit board 1; by surrounding and fixing the fixed bracket 3 to form a contact surface on the outer periphery of the fixed bracket 3, the contact area between the mounting bracket 10 and the fixed bracket 3 is large, and the fixed bracket 3 can also be limited in multiple directions, further improving the stability of the position of the fixed bracket 3 itself.

[0051] In specific implementation, the mounting bracket is a U-shaped bracket, and its two side arms respectively have mounting ears 1010. The bottom of the mounting bracket 10 can support the lower surface of the fixed bracket 3, and the two side walls of the mounting bracket 10 can clamp the fixed bracket 3 in the left and right directions, and finally connected to the device housing 6 through the mounting ears 1010. On this basis, in order to further fix the mounting bracket 10 and the fixed bracket 3 to prevent the fixed bracket 3 from falling off, the bottom of the mounting bracket 10 is fixedly connected to the bottom of the positioning platform 310 through the fastener 5. During assembly, the mounting bracket 10, the fixed bracket 3 and the main conductive bar 2 can be formed into an integral module, and then assembled with the main body of the functional module to form a modular installation method with higher assembly efficiency.

[0052] In some embodiments, see Figures 10 to 17 The fixed bracket 3 includes a positioning platform 310, a first partition 325 disposed on one side of the positioning platform 310, and a second partition 326 disposed on the other side of the positioning platform 310, and a wiring isolation space 301 is formed between the first partition 325 and the second partition 326; the first partition 325 can be spliced ​​with the second partition 326 in the adjacent fixed bracket 3 along the left-right direction, and the first partition 325 and the second partition 326 are respectively overlapped and fixed on the board surface of the circuit board 1. The number of fixed brackets 3 can be selectively set according to actual assembly requirements, and then the number of wiring isolation spaces 301 of the entire bracket can be determined, which can adapt to the installation requirements of different numbers or models of main conductive bars 2, and is more flexible to use.

[0053] Among them, the splicing method of the first partition 325 and the second partition 326 is exemplified as follows: 1) The splicing structure between the two is Velcro, and one of LOOP or HOOK is set on the side of the first partition 325 facing the second partition 326, and the other of LOOP or HOOK is set on the side of the second partition 326 facing the first partition 325. 2) The splicing structure between the two is an adhesive structure, which includes an adhesive layer, and one of the first partition 325 and the second partition 326 is provided with an adhesive layer; wherein, the implementation method of the adhesive layer includes but is not limited to a silicone layer. 3) The splicing structure between the two is a snap-on structure, and one of the first partition 325 and the second partition 326 is provided with a straight-insert buckle, and the other of the first partition 325 and the second partition 326 is correspondingly provided with a snap-on.

[0054] More specifically, in order to achieve effective pre-positioning of the first partition plate 325 and the second partition plate 326 and improve the splicing qualification rate while ensuring the splicing efficiency, a first pre-positioning structure is provided between the first partition plate 325 and the second partition plate 326 .

[0055] The first type of first pre-positioning structure is implemented as follows: the first pre-positioning structure includes at least two conical guide posts provided on one of the first partition 325 and the second partition 326, and also includes at least two guide holes provided on the other of the first partition 325 and the second partition 326, the large end of the conical guide post is connected to the corresponding first partition 325 or the second partition 326, and a plurality of conical guide posts are diagonally distributed on the first partition 325 or the second partition 326, the guide holes correspond to the conical guide posts one by one, and the inner diameter of the guide hole is the same as the outer diameter of the large end of the conical guide post. When the splicing is aligned, the small end of the conical guide post is inserted into the guide hole, and the conical surface of the conical guide post guides the guide hole. In the process of the first partition 325 and the second partition 326 gradually approaching each other, the conical guide post coincides with the center line of the guide hole, and the splicing structure is completed at the same time.

[0056] The implementation method of the second type of first pre-positioning structure is as follows: the first pre-positioning structure includes at least three positioning claws provided on one of the first partition plate 325 and the second partition plate 326, and the at least three positioning claws are evenly arranged in the edge area of ​​the splicing surface of the first partition plate 325 or the second partition plate 326 along the circumference of the first partition plate 325 or the second partition plate 326, and each positioning claw is inclined and divergently arranged in a direction away from the central axis of the corresponding splicing surface, and the inclination angle of each positioning claw is the same; the edge of the splicing surface of the other one of the first partition plate 325 and the second partition plate 326 is provided with a positioning convex strip along its own circumference, and the positioning convex strip is provided with a turn corresponding to the position of the positioning claw. When the splicing is in position, the free end of each positioning claw first abuts against the splicing surface on the inner side of the positioning convex ring, and has a certain distance from the positioning convex ring. As the distance between the first partition plate 325 and the second partition plate 326 decreases, the positioning claw is compressed and elastically deformed at a larger inclination angle, and the free end of the positioning claw gradually approaches the tip of the corresponding bend. When each positioning claw abuts against the tip of the corresponding bend, the first partition plate 325 and the second partition plate 326 are opposite, and the first partition plate 325 and the second partition plate 326 cannot rotate relative to each other, and the splicing structure is completed at the same time; if the first partition plate 325 is not opposite to the second partition plate 326 during the assembly process, when the first partition plate 325 and the second partition plate 326 can no longer approach each other, the degree of pressure on each positioning claw will be different, resulting in the problem of mutual inclination between the first partition plate 325 and the second partition plate 326. At this time, the first partition plate 325 or the second partition plate 326 is appropriately rotated. When it is adjusted to make the pressure conditions of each positioning claw the same, the assembly can continue. This implementation is more suitable for a splicing method in which the splicing structure is a snap-on structure.

[0057] The implementation method of the third type of first pre-positioning structure is as follows: the first pre-positioning structure includes a first bent plate, a second bent plate and two pressure sensors; the first bent plate is connected to the corner of the lower rear side of the first partition 325 and extends toward the second partition 326, and the cross-section of the first bent plate is L-shaped with the same turning trend as the corner of the lower rear side of the first partition 325; the second bent plate is connected to the corner of the lower rear side of the second partition 326 and extends toward the first partition 325, and the cross-section of the second bent plate is L-shaped with the same turning trend as the corner of the lower rear side of the second partition 326; two pressure sensing patches are respectively connected to the adjacent two sides of the first bent plate facing the first partition 325. During assembly, the two adjacent side surfaces of the second bent plate away from the second partition 326 are in contact with the two adjacent side surfaces of the first bent plate toward the first partition 325 respectively. As the first partition 325 and the second partition 326 approach each other, the second bent plate slides on the first bent plate. At this time, the second bent plate needs to be fully in contact with the first bent plate at all times to ensure that the first partition 325 is facing the second partition 326. Detecting whether the second bent plate is always in full contact with the first bent plate is achieved through two pressure sensors. If both pressure sensing patches are under pressure, it is determined that the second bent plate is fully in contact with the first bent plate. If one of the pressure sensing patches does not detect a pressure value, it means that the corresponding side of the second bent plate and the first bent plate are not in contact. The posture of the first bent plate and the second bent plate can be adjusted accordingly.

[0058] In some embodiments, see Figures 15 to 17 The fixed bracket 3 also includes a splicing bracket 380, which is arranged between the first partition 325 and the second partition 326 on both sides of the same positioning platform 310. The splicing bracket 380 includes a first frame 381 connected to the first partition 325 and a second frame 382 connected to the second partition 326. The first frame 381 and the second frame 382 are spliced ​​along the left and right direction; the positioning platform 310 is divided into a first positioning section 311 and a second positioning section 312 spliced ​​with each other, the first positioning section 311 is connected to the first partition 325, and the second positioning section 312 is connected to the second partition 326. This embodiment can realize splicing according to the number of the first conductive bar 210 and the number of the second rear connecting plates 221 of the second conductive bar 220, and flexibly set the number of wiring isolation spaces 301, which is more flexible to use.

[0059] It should be noted that the solution of providing the splicing bracket 380 and the solution of providing the first partition plate 325 and the second partition plate 326 can be used separately or in combination.

[0060] In some embodiments, see Figures 10 to 14The fixed bracket 3 includes a positioning platform 310, a lower partition 327 arranged on both sides of the positioning platform 310, a clamping bracket 390 arranged above the positioning platform 310, and an upper partition 328 arranged on both sides of the clamping bracket 390; the upper partition 328 and the lower partition 327 are spliced ​​correspondingly up and down, the clamping bracket 390 and the positioning platform 310 cooperate to clamp the main conductive bar 2 up and down, the upper partitions 328 on both sides and the lower partitions 327 on both sides cooperate to form a wiring isolation space 301, and the lower partition 327 is overlapped and fixed to the board surface of the circuit board 1.

[0061] In this embodiment, the fixing bracket 3 is split into upper and lower parts, the upper partition 328 and the clamping bracket 390 form a whole, and the lower partition 327 and the positioning platform 310 form a whole. When installing, the main conductive bar 2 is placed at a designated position on the positioning platform 310, and then the lower clamping bracket 390 and the upper partition 328 are clamped and fixed. The reverse operation can be performed to achieve disassembly, so as to replace the first conductive bar 210 of a different model. It should be noted that if the second conductive bar 220 is also compatible, the loading and unloading method of the second conductive bar 220 and the fixing bracket 3 of this embodiment is similar to the loading and unloading method of the first conductive bar 210 described above, and will not be repeated here.

[0062] In specific implementation, the implementation methods of the detachable connection between the upper partition 328 and the lower partition 327 are exemplified as follows: 1) An adhesive layer is provided at the lower edge of the upper partition 328, and the upper partition 328 and the lower partition 327 are bonded together, and disassembly is achieved by tearing; 2) An insertion column is provided at the lower edge of the upper partition 328, and a insertion hole is provided at the upper edge of the lower partition 327, and the insertion hole and the insertion column are interference fit up and down; 3) A guide groove that passes through the front and back is provided at the lower edge of the upper partition 328, and a guide rail that is slidably plugged into the guide groove back and forth is provided at the upper edge of the lower partition 327.

[0063] In some specific embodiments, based on the implementation of clamping and fixing the main conductive bar 2 in the up-down direction by the clamping bracket 390 and the positioning platform 310, in order to limit the main conductive bar 2 in the direction perpendicular to the up-down direction, a positioning column 13 is set on one of the main conductive bar 2 and the positioning platform 310, and a positioning hole is set on the other of the main conductive bar 2 and the positioning platform 310, and the positioning column 13 and the positioning hole are plugged into each other to achieve the limit in the direction perpendicular to the up-down direction. With the above clamping and limiting, the main conductive bar 2 can be locked on the fixing bracket 3. In specific implementation, if the left-right width of the wiring isolation space 301 is relatively large, it is necessary to set a plurality of positioning holes and a plurality of positioning columns 13 to prevent the conductive bar from rotating, or the positioning column 13 is set as an elliptical column or a polygonal prism, and the positioning hole is set in accordance with the shape, which can also play an anti-rotation role; if the left-right width of the wiring isolation space 301 is relatively small, the main conductive bar 2 can be limited to prevent rotation, and only one positioning hole and positioning column 13 is required.

[0064] More specifically, on the basis that the partition 320 includes an upper partition 328 and a lower partition 327, in order to achieve the effect that the first conductive bar 210 and the second conductive bar 220 can be replaced, the upper partition 328 and the lower partition 327 both include a main partition 321 and a front removable plate 322. In specific implementation, the front removable plate 322 of the upper partition 328 and the front removable plate 322 of the lower partition 327 are separately provided and can be disassembled separately. The disassembly and assembly method can refer to the cooperation between the upper partition 328 and the lower partition 327, which will not be listed here one by one; or, the front removable plate 322 of the upper partition 328 and the front removable plate 322 of the lower partition 327 are integrally provided, and can be completely disassembled in one action.

[0065] In some embodiments, see Figures 15 to 17 Based on the cooperation between the clamping bracket 390 and the positioning platform 310, in order to simplify the structure and save space, the clamping bracket 390 and the splicing bracket 380 can be integrated. The clamping bracket 390 in the figure is also the splicing bracket 380, and the clamping and splicing functions are realized through the same bracket structure.

[0066] In other embodiments, the clamping bracket 390 and the first foolproof bracket 340 can be integrated (eg, Figures 10 to 14 As shown), the clamping bracket 390 in the figure is also the first anti-foolproof bracket 340, and the clamping and anti-foolproof functions are achieved through the same bracket structure.

[0067] In some other embodiments, the clamping bracket 390, the splicing bracket 380 and the first fool-proof bracket 340 can be integrated to achieve the functions of clamping, splicing and fool-proofing through the same bracket structure.

[0068] In some embodiments, see Figure 1 Figures 7 to 9 The lower part of the partition 320 is provided with a marking groove 330 that runs through from left to right. The front side of the marking groove 330 is a visible area. The label 11 can be slidably inserted into the marking groove 330. The information on the label 11 is displayed through the visible area to facilitate the identification of the wiring information of the main conductive bar 2. More specifically, the marking groove 330 runs through the bottom of each partition 320 in the left-right direction. The partition 320 can segment the information on the label 11 so that each wiring isolation space 301 corresponds to a section of label 11 information, which is convenient for operators to check the labels. The visible area of ​​the marking groove 330 is implemented as follows: the front side of the marking groove 330 is left blank, or a transparent window is set on the front side of the marking groove 330. The material of the transparent window can be acrylic, glass, etc.
