Particularly, when the current level of the electric module is high, a copper bar wiring manner is generally required, that is, the lead terminal is a terminal corresponding to the shape of the copper bar.

Example 1

Referring to fig. 1-2, embodiment 1 of the present invention provides a wiring structure for introducing electric energy into an electrical module or leading out electric energy from the electrical module. In other words, the utility model discloses a wiring structure can be used for with the input coupling of electric module, also can be used for with the output coupling of electric module to be used for the input wiring or the output wiring of electric module respectively.

In this embodiment, the electrical module (not shown) has three transverse lead terminals (not shown) that are equally spaced along a first direction. It should be noted that, the present invention is not limited to the fact that each component is arranged along the first direction at equal intervals, but means that each component is arranged along the first direction at equal intervals after two projections along the other two directions orthogonal to the first direction (e.g. along the second direction and the third direction in sequence).

In this embodiment, the wiring structure includes three lead elements 10 and three wiring elements.

Each of the lead elements 10 is connected to a lead terminal of the electrical module, and each of the lead elements 10 has a first overcurrent cross section which is substantially rectangular and has a long side parallel to the first direction.

Each of the wiring units corresponds to and is electrically connected to each of the lead units 10, and each of the wiring units has a wiring portion 22, and a second overcurrent section having a substantially rectangular shape and a short side parallel to the first direction is defined in the wiring portion 22. The long side of the first overcurrent cross section is longer than the short side of the second overcurrent cross section, and the wiring portions 22 are equidistant along the first direction.

In the wiring structure of the present embodiment, the lead unit 10 is electrically connected to the electrical module and the wiring portion 22 is provided with the corresponding wiring unit, so that the wiring structure can provide external wiring for the electrical module. On this basis, the lead unit 10 is further configured such that the long side of the corresponding overcurrent section is parallel to a first direction, thereby being suitable for corresponding electrical connection with each lead terminal with the lead terminal lying horizontally, and the wiring portion 22 of the wiring unit is configured such that the short side of the corresponding overcurrent section is parallel to the first direction, in other words, each wiring portion 22 is in a vertical state in the first direction, so that the configuration of the wiring portion 22 is suitable for reducing the space occupation of the wiring portion 22 in the first direction on the basis of maintaining the overall current carrying capacity of the wiring structure, effectively increasing the wiring operation space with the lead terminal lying horizontally, and facilitating the wiring operation of the electrical module with a user in a larger operation space. In addition, the wiring portions 22 are arranged equidistantly along the first direction, so that the wiring structure has a symmetrical characteristic in the first direction, and the process attractiveness is good after the wiring is finished.

In this embodiment, each lead unit 10 is configured as a lead busbar 10, the first overcurrent cross section is defined therein, and each lead busbar 10 extends along a third direction shown in the figure, and the third direction is perpendicular to the first direction. In this embodiment, each lead unit 10 is equidistant along the first direction, and the lead busbar 10 located in the middle along the first direction and the lead busbars 10 on both sides thereof are arranged in a staggered manner in the first direction.

Each of the wiring units is configured to include at least one wiring busbar having a crossover portion 21 and the wiring portion 22 extending in directions perpendicular to each other. Specifically, a third overcurrent section which is approximately rectangular is defined in the overlapping part 21, long sides of the third overcurrent section and long sides of the second overcurrent section are parallel to each other, and short sides of the third overcurrent section and the first overcurrent section are parallel to each other, so that the wiring busbar is suitable for overlapping the corresponding lead busbar 10 through the overlapping part 21 and establishing an electrical connection relation. The wire connecting portion 22 extends in a second direction shown in the drawing, which is perpendicular to the first direction and the third direction. In this embodiment, the wire connection portions 22 are also arranged at equal intervals along the first direction.

It goes without saying that the lead busbar 10 and the wiring busbar can be configured as copper bars.

It can be seen that the lead unit 10 includes a lead busbar 10, the wiring unit includes a wiring busbar having a lap portion 21 and a wiring portion 22 perpendicular to each other, a long side of an overcurrent cross section of the lap portion 21 is parallel to a long side of a second overcurrent cross section, and thus the wiring busbar is suitable for adopting an integral busbar having a good current-carrying capacity. In addition, the short side of the overcurrent section of the lap joint part 21 is parallel to the short side of the first overcurrent section, so that the lap joint part 21 is parallel to the lead busbar 10 and is suitable for being lapped therewith, and the lead unit 10 and the wiring part 22 of the wiring unit can still be electrically connected under the condition that the short sides of the respective overcurrent sections are perpendicular to each other. In addition, each wiring portion 22 is arranged along the first direction at equal intervals, so that each wiring portion 22 is basically and completely symmetrical in the first direction, and the process attractiveness after wiring is further improved.

Further, the plurality of wiring units are a first wiring unit 20A, a second wiring unit 20B and a third wiring unit 20C which are sequentially arranged along the first direction.

The wiring busbars included in the first wiring unit 20A and the third wiring unit 20C are both L-shaped busbars, so that the first wiring unit 20A and the third wiring unit 20C are both L-shaped structures, and two mutually perpendicular parts on each wiring busbar respectively form a lapping part 21 and a wiring part 22 of the corresponding wiring unit.

The bridging portion 21 and the wiring portion 22 of the wiring busbar included in the second wiring unit 20B are fitted to each other and make the second wiring unit 20B in a T-shaped configuration. The first wire connection unit 20A and the third wire connection unit 20C are opposed to each other and are symmetrically disposed with respect to the wire connection portion 22 of the second wire connection unit 20B.

It can be seen that the first wiring unit 20A and the third wiring unit 20C are arranged in an L shape and have an L-shaped configuration, and the second wiring unit 20B has a T-shaped configuration, so that the first wiring unit 20A and the third wiring unit 20C can be symmetrical with respect to the wiring portion 22 of the second wiring unit 20B, which not only realizes equal spacing of the wiring portions 22 of each wiring unit along the first direction and better symmetry, but also can further increase the spacing of the wiring portions 22 along the first direction to increase the wiring operation space when the wiring portions 22 are vertically arranged, as shown in fig. 2, because the two wiring portions are oppositely arranged.

Specifically, in other embodiments, the second connection unit 20B may adopt a T-shaped bus bar as its connection bus bar, and two mutually perpendicular portions of the T-shaped bus bar respectively constitute the overlapping portion 21 and the connection portion 22 of the second connection unit 20B. In the embodiment using the T-shaped busbar, the advantages are that the structure is simple, the purchase is easy, and the cost is low, but when the user has more diversified wiring requirements, and thus the length of the wiring part 22 needs to be changed correspondingly, the T-shaped busbar has a limited specification on the market, and thus the requirement is difficult to meet.

In order to overcome the above-mentioned drawback of the T-shaped busbar, in the present embodiment, the second connection unit 20B includes two connection busbars which are opposite to each other and are both configured as an L-shaped busbar, and two mutually perpendicular portions of the two connection busbars respectively form the lap portion 21 and the connection portion 22 of the second connection unit 20B. The two wire connecting portions 22 of the second wire connecting unit 20B are arranged in parallel and overlapped with each other to establish a parallel electrical connection relationship, and the two overlapping portions 21 are arranged oppositely along the first direction and are both adapted to overlap with the corresponding lead busbar 10.

It should be noted that, in the present invention, the mutually opposite means that the inner angles of the two structures having the L-shaped structures are arranged oppositely, and the mutually opposite means that the outer angles of the two structures are arranged oppositely.

Therefore, the wiring busbar of the second wiring unit 20B is formed by arranging two L-shaped busbar in opposite directions, and compared with a T-shaped busbar having only several fixed sizes of the length of the wiring part 22, the extension size of the wiring part 22 of the second wiring unit 20B formed in this way can be freely customized, and the wiring busbar has higher expansibility, and can meet more diversified wiring requirements of users.

Further, in the present embodiment, orthographic projections of the overlapping parts 21 of the first wire connecting unit 20A and the third wire connecting unit 20C on a plane perpendicular to the first direction are overlapped and are both shifted from the orthographic projection of the overlapping part 21 of the second wire connecting unit 20B on the same plane. Thus, each of the wire connection units is disposed corresponding to each of the lead units 10, that is, the overlapping portion 21 of the second wire connection unit 20B is disposed to be offset from the overlapping portion 21 of the first wire connection unit 20A and the third wire connection unit 20C, so that the second wire connection unit 20B gives way for the first wire connection unit 20A and the third wire connection unit 20C in the first direction by a certain space, and thus the first wire connection unit 20A and the third wire connection unit 20C can be closer in the first direction, and the overall space occupation of each wire connection unit in the first direction is reduced on the basis of the same pitch of the respective wire connection portions 22.

The present embodiment further provides an associated electrical device (not shown in the drawings) based on the wiring structure, the electrical device including an electrical module and the wiring structure of the present embodiment. The electrical module has several lead terminals as described above. The number of lead elements 10 in the wiring structure corresponds to the number of lead terminals to lead electric energy into or out of the electric module. It goes without saying that the electrical apparatus adopts the aforementioned wiring structure, thus inheriting all the advantages thereof.

Example 2

Referring to fig. 3 to 8, the present embodiment provides an output wiring cabinet, and in this specific application environment of the output wiring cabinet, the wiring structure of the present embodiment is modified based on the wiring structure of embodiment 1 to form the wiring structure of the present embodiment.

Referring first to fig. 7-8, the output wiring cabinet is used to output three power devices in parallel. In this embodiment, the power device is a UPS (not shown) having a three-phase ac output. It goes without saying that the power plant may also be another converter that can output three-phase alternating current, such as a photovoltaic inverter or the like.

The output connection cabinet comprises a frame 300, a cabinet body (not shown in the figure), and three switch modules 200 and connection structures fixedly arranged in the frame 300 and the cabinet body.

Each of the switch modules 200 is fixedly disposed in the cabinet body through a partition plate fixedly connected to the frame 300, and respectively corresponds to a power device and is used for controlling the power device to be turned on or off. In this embodiment, each of the switch modules 200 is a frame circuit breaker, an input end of each of the switch modules is electrically connected to a corresponding power device, an output end of each of the switch modules includes three lead terminals 210, and the three lead terminals 210 are arranged at equal intervals along the first direction and respectively correspond to output of U-phase alternating current, V-phase alternating current, and W-phase alternating current.

It will be appreciated that since each of the switch modules 200 has the above-mentioned three lead terminals 210 which are arranged laterally and respectively correspond to three-phase alternating current, the lead terminals 210 of each of the switch modules 200 correspond to each other one by one. In other words, each switch module 200 includes a set of corresponding lead terminals corresponding to three lead terminals of the U-phase alternating current, each switch module 200 includes a set of corresponding lead terminals corresponding to three lead terminals of the V-phase alternating current, and each switch module 200 includes a set of corresponding lead terminals corresponding to three lead terminals of the W-phase alternating current.

Referring to fig. 3 to 6, the wiring structure of the present embodiment is substantially the same as that of embodiment 1, and particularly, the wiring unit 120 is identical, and the difference between them is mainly the lead unit 110. The specific differences are as follows: (1) since each lead unit 110 corresponds to a plurality of switch modules 200 (the switch module 200 corresponds to the electric module of embodiment 1), the lead unit 110 of the present embodiment is correspondingly configured to include a plurality of flow guides 111 and a bus bar 112; (2) because the current-carrying capacity of each lead unit 110 and each wiring unit 120 needs to be correspondingly improved due to the confluence, the current-carrying capacity of the wiring structure is improved by overlapping the corresponding bus bars with the parallel bus bars.

Since the above difference (2) belongs to the adaptive adjustment of the current carrying capacity of the wiring structure, those skilled in the art can understand and implement the adjustment correspondingly with reference to the drawings of the present embodiment, and the present invention does not describe the details thereof, so that the difference (1) is mainly described below.

In this embodiment, the number of the lead wire units 110 of the wiring structure is three, which is the same as the number of the lead terminals 210 of each switch module 200, and each lead wire unit 110 corresponds to one group of the lead terminals corresponding to each other in each switch module 200. In other words, the three-lead wire unit 110 corresponds to the lead wires of the U-phase alternating current, the V-phase alternating current, and the W-phase alternating current of each switch module 200, respectively. It goes without saying that since each wiring unit 120 corresponds to each lead wire unit 110 one by one, three corresponding wiring units 120 also correspond to wiring outputs of the U-phase alternating current, the V-phase alternating current, and the W-phase alternating current of each switch module 200, respectively.

Specifically, each lead unit 110 includes a plurality of the drains 111 and a plurality of the confluence portions 112. The number of the current collectors 111 of each lead unit 110 corresponds to the number of the switch modules 200, so that each current collector 111 is electrically connected to one of the lead terminals 210 corresponding to each group. The confluence portion 112 defines the first flow cross section, and the confluence portion 112 of each lead unit 110 is overlapped with each current guiding portion 111 of the lead unit 110 and the wiring unit 120 corresponding to the lead unit 110, so as to establish an electrical connection relationship between the current guiding portions 111 and the corresponding wiring units 120 after confluence.

As can be seen from fig. 3 to 6, each of the current-guiding portions 111 is configured to be directly electrically connected to the current-guiding busbar 111 of each of the lead terminals 210, and the corresponding bus portion 112 is configured to be a bus bar 112, which is overlapped with each other and then further overlapped with the wiring busbar 120 of the wiring unit, and each of the wiring busbars 120 is provided with a plurality of wiring terminals at intervals along the extending direction thereof for a user to wire. In this embodiment, each drainage busbar 111 is fixed in the cabinet body through a connecting sheet fixedly connected with the frame 300, each busbar 112 is fixed in the cabinet body through a partition plate fixedly connected with the frame 300, each wiring busbar 120 is fixed in the cabinet body through an insulating plate fixedly connected with the partition plate, and each lapped busbar is locked through a threaded fastener.

It should be understood that the bus bar 112 of the present embodiment may directly adopt the structure of the lead bar 10 of embodiment 1, and the corresponding relationship between each drain bar 111 and the switch module 200 may be similar to the corresponding relationship between the lead bar 10 and the electrical module of embodiment 1, but the structure may be adaptively adjusted according to the position of the lead terminal 210 of the switch module 200. For example, in the present embodiment, the lead terminals 210 of each switch module 200 are arranged at equal intervals along the first direction, and the drain busbars 111 of each lead unit 110 are also arranged at equal intervals along the first direction and correspondingly extend along the second direction and the third direction to be overlapped with the corresponding bus bars 112, but it can be understood that the specific structure and arrangement manner of the drain busbars 111 are not limited thereto. It goes without saying that, as with the first overcurrent section, the long sides of the overcurrent sections of the respective portions of each drainage busbar 111 are also always parallel to the first direction, so that the integrated busbar is suitable for electrically connecting the switch module 200 and the busbar 112.

It can be seen that, because the output wiring cabinet of the present embodiment adopts the improved wiring structure based on embodiment 1, in addition to inheriting all the advantages of the wiring structure of embodiment 1, the output wiring cabinet also configures the lead unit 110 to include the plurality of drainage portions 111 and the one converging portion 112, and can establish an electrical connection relationship between each corresponding lead terminal 210 of each switch module 200 and the corresponding wiring unit 120 after converging, so that the wiring structure can be applied to more diversified wiring environments.
