[0003] In related electrical equipment such as inverters and combiner boxes, the on-board wiring logic is generally as follows: after the positive cable passes through the connector board end corresponding to the positive pole and before being connected to the DC switch, two or more cables generally achieve the merging function at the end multi-sink 1; for the same reason, the negative cable passes through the connector board end corresponding to the negative pole, and two or more cables also achieve the merging function at the end multi-sink 1. This wiring method not only requires complicated wiring operations and consumes a lot of cables, but also occupies a large amount of on-board space.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The gist of the present disclosure is to provide a wiring connector and an electrical device that solve the problems of complicated wiring operations, the large amount of cable consumption, and the large amount of space occupied inside the aircraft.

[0021] The following will clearly and completely describe the technical solutions in the disclosed embodiments, combining the drawings in the disclosed embodiments. Obviously, the described embodiments are not all of the embodiments in the disclosed embodiments, but only some of the embodiments in the disclosed embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the disclosed embodiments without performing creative work fall within the scope of protection of the disclosed embodiments.

[0022] 1 to 22, the present disclosure specifically provides a wiring connector, including a wire end unit 1 for electrically connecting to a first wiring cable 4, a board end unit 2 detachably connected to the wire end unit 1 and including a plurality of board end electrical connection portions 22 for electrically connecting to a second wiring cable 6, and a junction unit 3 attached to the board end unit 2 and including at least one junction portion 31 for electrically connecting at least two board end electrical connection portions 22 of the same polarity to one second wiring cable 6.

[0023] In actual application, this wiring connector is installed by attaching a junction unit 3 to a board end unit 2, and the junction unit 3 includes at least one junction section 31 for electrically connecting at least two board end electrical connection sections 22 of the same polarity on the board end unit 2 to one second wiring cable 6. This allows the wiring connector to not only achieve the connection function between the first wiring cable 4 and the second wiring cable 6, but also to have a junction function. This eliminates the need for an external wiring cable to perform the junction connection, significantly reducing the amount of wiring cable required, contributing to cost savings, simplifying the wiring operation, and reducing the space occupied on board the aircraft.

[0024] The wire end unit 1 includes at least two wire end electrical connections 12 electrically connected to the first connecting cables 4, and the wire end electrical connections 12 are fitted into the board end electrical connections 22, with the number of board end electrical connections 22 being equal to or greater than the number of wire end electrical connections 12. The wire end electrical connections 12 may include a positive wire end electrical connection portion electrically connected to the positive connecting cable 41 and / or a negative wire end electrical connection portion electrically connected to the negative connecting cable 42. For the same reason, the board end electrical connections 22 may include a positive board end electrical connection portion fitted into the positive wire end electrical connection portion and / or a negative board end electrical connection portion fitted into the negative wire end electrical connection portion. For example, in the actual application process, the wiring connector 10 may be specifically designed to have the functions of positive and negative connection at the same time. The circuit principle diagram can be specifically referred to in FIG. 1. In this case, the wire end electrical connection part 12 has a positive wire end electrical connection part connected to the positive connection cable 41 and a negative wire end electrical connection part connected to the negative connection cable 42. At the same time, the board end electrical connection part 22 has a positive board electrical connection part respectively connected to the positive wire end electrical connection part. Of course, the junction 31 of the corresponding junction unit 3 also has a positive junction 311 and a negative junction 312, and the positive junction 311 is used to electrically connect multiple positive board end electrical connections that need to be joined to a single second wiring cable 6, and the negative junction 312 is used to electrically connect multiple negative board end electrical connections that need to be joined to a single second wiring cable 6.

[0025] Of course, it should be understood that the wiring connector 10 may also be designed as two independent connector structures, a positive wiring connector and a negative wiring connector, the circuit principle diagram of which can be specifically referred to in FIG. 2, and can be selected and arranged according to actual requirements in the actual application process, and no further specific limitations are provided herein.

[0026] Furthermore, the connection between the junction 31 and the board end electrical connection 22 can be achieved by at least one of fastener connection, welding, crimping, fastening, adhesive, etc., and in this disclosure, fastener connection is preferred because it is more convenient to connect and disconnect. Of course, in the actual application process, it can be selected and arranged according to actual requirements, and no specific limitations are provided here.

[0027] Furthermore, as shown in Figures 1 and 2, those skilled in the art will understand that the line connector can be specifically applied to electrical equipment such as inverters, combiner boxes, etc., and therefore, the junction cable 6 is usually provided with a switch 100.

[0028] 4, 10 and 11, the junction unit 3 may specifically include a junction circuit board 30, and the junction portion 31 may be mounted on the junction circuit board 30. Designing the junction portion 31 on the junction circuit board 30 makes the mounting arrangement of the junction portion 31 more convenient. Of course, it should be understood that designing the junction portion 31 on the junction circuit board 30 is merely an example of an embodiment of the present disclosure, and in the actual application process, the junction portion 31 may be disposed separately from the junction circuit board 30, and may be selected and disposed according to actual requirements.

[0029] Further, other functional components may be further attached to the junction circuit board 30. For example, referring to Fig. 3 in combination with Fig. 10, the junction unit 3 may further include a safety capacitor 32 attached to the junction circuit board 30, the safety capacitor 32 being grounded via a ground path, the junction portion 31 including a positive junction portion 311 electrically connected to at least two positive board end electrical connections 22 and a negative junction portion 312 electrically connected to at least two negative board end electrical connections 22, and at least one safety capacitor 32 is connected to each of the positive junction portion 311 and the negative junction portion 312. By providing the safety capacitor, an EMC shielding function can be achieved.

[0030] Furthermore, those skilled in the art should understand that when there are multiple safety capacitors 32 connected to the positive electrode junction 311, the safety capacitors 32 connected to each positive electrode junction 311 may be arranged in series or in parallel, and for the same reason, when there are multiple safety capacitors 32 connected to the negative electrode junction 312, the safety capacitors 32 connected to each negative electrode junction 312 may be arranged in series or in parallel.

[0031] In a further embodiment, the safety capacitor 32 connected to the positive electrode junction 311 and the safety capacitor 32 connected to the negative electrode junction 312 may be designed as a common ground path, the circuit principle of which can be seen in Figure 3, and the common ground path design simplifies the grounding structure of the safety capacitor. Of course, it should be understood that in actual application, the safety capacitor 32 connected to the positive electrode junction 311 and the safety capacitor 32 connected to the negative electrode junction 312 may be designed as separate ground paths, which can be selected and arranged according to actual requirements in actual application, and no further specific limitations are provided herein.

[0032] In a further embodiment, as shown in Figures 10 and 11, the common ground path can specifically employ a ground pin 33 connected between the safety capacitor 32 and the chassis wall 5. Of course, other ground path structures commonly used by those skilled in the art can also be employed, such as a metal dome, a conductive wire, or a conductive tape connected between the safety capacitor 32 and the chassis wall 5. These can be selected and arranged according to actual requirements during actual application, and are not specifically limited herein.

[0033] In some other specific embodiments, referring to Figures 4 to 7, the board end unit 2 may further include a sensor unit 8 attached to the signal cable unit 7. By attaching the sensor unit to the board end unit 2, the wiring connector 10 itself can have a corresponding detection function, and there is no need to consider additional sensor-related components during wiring operations. This increases the integration level of the wiring connector 10, contributes to reducing the overall volume, and reduces the complexity of wiring operations. Specifically, the sensor unit 8 may include a signal socket above the sensor PCB, and the signal cable unit 7 engages with the signal socket to achieve electrical connection, making this connection method more convenient to attach and detach.

[0034] The signal cable unit 7, the junction cable 6, etc. may be part of the wiring connector 10, or may be members independent of the wiring connector 10.

[0035] In a further embodiment, the sensor unit 8 may specifically include at least one of five types of sensor elements: a current sensor, a voltage sensor, an arc sensor, a temperature sensor, and a humidity sensor. Of course, it should be understood that the sensor types listed above are merely examples of the embodiments of the present disclosure, and in the actual application process, sensor elements with other corresponding functions may be selected according to actual requirements. For a specific sensor unit 8, a sensor element with one of these functions may be selected, or a combination of multiple sensor units may be adopted, and no further specific limitations are provided herein.

[0036] Furthermore, the specific structural form of the sensor member 80 of the sensor unit 8 may be provided at the board-end electrical connection portion 22, and the arrangement method at the board-end electrical connection portion 22 may specifically include at least one of four arrangement methods: pass-through type, series type, proximity type, and parallel type. For details, refer to Figures 12 to 15.

[0037] In some specific embodiments, the specific structural forms of the wire-end electrical connection 12 and the board-end electrical connection 22 may be designed such that one of them is a female pin and the other is a male pin. The female-to-male pin engagement design makes the electrical connection more convenient and relatively stable and reliable. Of course, it is understood that other structural forms of electrical connection structures may be designed in the actual application process, and no specific limitations are provided herein.

[0038] In some specific embodiments, the wire end unit 1 further includes at least one wire end mechanical connection 11, and the wire end electrical connection 12 is provided on the wire end mechanical connection 11. The board end unit 2 further includes a board end body 20 for detachably fastening to the chassis wall 5 and a board end mechanical connection 21 attached to the board end body 20, and the board end electrical connection 22 is provided on the board end mechanical connection 21, and the board end mechanical connection is matingly connected to the wire end mechanical connection. The design of the board end mechanical connection 21 and the wire end mechanical connection 11 makes it easier to mechanically connect the board end unit 2 and the wire end unit 1. Additionally, the design of the board end body 20 makes it easier to secure the board end unit 2 to the chassis wall 5. Referring to FIGS. 7 to 10 , the board end body 20 can be secured to the chassis wall 5 by using a lock nut 23 in cooperation with a seal ring 24.

[0039] The number of wire-end mechanical connecting portions 11 may be one or may be selected to be multiple.

[0040] Referring to Figure 4 and combining Figures 16 to 22, as an example, a case where the number of wire-end mechanical connection parts 11 is designed to be multiple, each wire-end mechanical connection part 11 is provided with at least one wire-end electrical connection part 12, and the board-end mechanical connection part 21 and the wire-end mechanical connection part 11 are mated and connected in a detachable manner. For example, referring to FIG. 4 and combining FIGS. 16 to 20, each wire-end mechanical connection portion 11 is provided with one wire-end electrical connection portion 12, and each wire-end mechanical connection portion 11 has an interior mounting cavity through which the wire-end electrical connection portion 12 (specifically, it may have a pin structure) passes. The first connection cable 4 is connected to the wire-end electrical connection portion 12, and a rubber plug 112 may be inserted into the first connection cable 4 inserted into the interior of the wire-end mechanical connection portion 11. The wire-end mechanical connection portion 11 has an engagement cavity that tightly engages with the rubber plug 112, and the rubber plug 112 can be firmly pressed into the engagement cavity by a fixing portion 113, thereby The rubber plug 112 can provide a seal between the first connection cable 4 and the wire-end mechanical connection portion 11. For example, as shown in FIG. 21 , two adjacent wire-end electrical connection portions 12 of four wire-end electrical connection portions 12 are attached to one wire-end mechanical connection portion 11, and the other two wire-end electrical connection portions 12 are connected to independent wire-end mechanical connection portions 11, and as shown in FIG. 22 , two diagonally arranged wire-end electrical connection portions 12 of four wire-end electrical connection portions 12 are attached to one wire-end mechanical connection portion 11, and the other two wire-end electrical connection portions 12 are connected to independent wire-end mechanical connection portions 11. As shown in FIG. 4 , the shape of the board end body 20 that engages with and attaches to the chassis wall 5 is preferably rectangular, but other shapes may also be employed. The shape can be specifically configured according to actual requirements in the actual application process, and is not specifically limited herein.

[0041] In a further embodiment, the detachable connection between the wire-end mechanical connection part 11 and the board-end mechanical connection part 21 may be specifically an engagement type, for example, as described with reference to FIG. 16, an in-line engagement type of notch and tab may be adopted, specifically, a notch may be provided on the board-end mechanical connection part 21 and a tab may be provided on the wire-end mechanical connection part 11, or a tab may be provided on the board-end mechanical connection part 21 and a notch may be provided on the wire-end mechanical connection part 11, and further, for example, as shown in FIG. As shown in FIG. 20, a rotary locking manner of a rotary locking member and a groove is adopted, specifically, a groove may be provided on the board end machine connection part 21 and a rotary locking member may be provided on the wire end machine connection part 11, or a rotary locking member may be provided on the board end machine connection part 21 and a groove may be provided on the wire end machine connection part 11. In addition, to facilitate the attachment and detachment operation, the corresponding wire end machine connection part 11 may further be provided with a convex structure to facilitate the user to perform the rotation operation. Of course, it should be understood that the above-mentioned attachment manner is only one example of the detachable connection of the embodiment of the present disclosure, and in actual application, other detachable connection manners may also be adopted, such as a screw connection manner, and are not specifically limited herein.

[0042] In some more specific implementations, when each wire-end mechanical connection 11 is provided with at least one wire-end electrical connection 12, a sealing member 9 may be further provided in the engagement gap between the wire-end mechanical connection 11 and the board-end mechanical connection 21. The design of the sealing member 9 can significantly improve the waterproof performance of the connection between the wire-end mechanical connection 11 and the board-end mechanical connection 21. For a specific structural form of the sealing member 9, see FIG. 18. The sealing member 9 may be specifically disposed in the circumferential engagement gap between the wire-end mechanical connection 11 and the board-end mechanical connection 21, or may be designed in a structural form as shown in FIG. 19, i.e., the sealing member 9 is disposed in the engagement end gap between the wire-end mechanical connection 11 and the board-end mechanical connection 21.

[0043] In addition, it is preferable that the wire-end machine connection part 11 adopts an insulating material so as to have a function of preventing electric shock when the user performs the wire connection operation, that is, the safety of the person can be guaranteed when inserting or removing the wire-end unit 1 without the person's hands touching the metal conductor part.

[0044] 5 to 7, taking the example of a design in which the number of wire-end mechanical connection parts 11 is one, the wire-end mechanical connection part 11 is arranged as a wire-end collecting cover that mounts and fixes each of the wire-end electrical connection parts 12, and the wire-end collecting cover is detachably connected to the board end body 20. Specifically, the wire-end collecting cover may include a fixing seat 111 and a fixing part 113, the fixing part 113 is detachably connected to the board end mechanical connection part 21, an installation cavity for installing the fixing seat 111 is formed in the board end mechanical connection part 21, and the fixing part 113 is used to lock the fixing seat 111 in the installation cavity. The wire-end mechanical connection part 11 secures a plurality of wire-end electrical connection parts 12 via the fixing seats 111, and is detachably connected to the board-end mechanical connection part 21 via the fixing parts 113, thereby locking the fixing seats 111 into the mounting cavities of the board-end mechanical connection part 21, and simultaneously completing an electrical connection between the wire-end electrical connection parts 12 of the fixing seats 111 and the board-end electrical connection parts 22 of the board-end body 20. That is, the wire-end mechanical connection part 11 completes a mechanical connection with the board-end mechanical connection part 21, and at the same time, the wire-end electrical connection parts 12 and the board-end electrical connection parts 22 are also completed electrically, making the operation very simple and convenient. Note that the specific structural form for realizing the detachable connection between the board-end mechanical connection part 21 and the fixing parts 113 may be a screw connection or a snap connection, and can be selected and arranged according to actual requirements in the actual application process, and is not specifically limited herein.

[0045] 8 and 9 , the wire-end mechanical connection part 11 may further be provided with a connecting seat 114, which has a mounting cavity for mounting the fixing seat 111. One end of the connecting seat 114 is detachably connected to the board-end mechanical connection part 21, and the other end is detachably connected to the fixing part 113. The connecting seat 114 may specifically include an engaging part 1141 that engages with the board-end mechanical connection part 21 of the board-end body 20, and a mounting part 1142 for mounting the fixing seat 111. The fixing part 113 is detachably connected to the mounting part 1142 (e.g., by threading, in which case the fixing part 113 may specifically be a tightening nut) and is used to lock the fixing seat 111 to the mounting part 1142. Designed in this structural form, the insertion-engagement connection between the wire-end electrical connection part 12 and the board-end electrical connection part 22 makes alignment, installation, and maintenance replacement operations more convenient.

[0046] In a further embodiment, as shown with reference to FIG. 8, the engaging portion 1141 and the mounting portion 1142 may be specifically designed as an integrated structure, or as shown with reference to FIG. 9, they may also be designed as separate structures. When the engaging portion 1141 and the mounting portion 1142 are separate structures, as shown in FIG. 9, the engaging portion 1141 engages with the board end machine connection portion 21, thereby firmly pressing and fixing the mounting portion 1142 to the board end machine connection portion 21. The advantage of the integrated structure is that processing is more convenient, and the advantage of the separate structure is that if one component is damaged, the entire component does not need to be discarded, but only one component needs to be replaced, which further contributes to saving maintenance costs and makes operation more flexible and convenient. In actual application, they can be selected and arranged according to specific requirements, and are not specifically limited herein.

[0047] 4, 7 and 8, in a further embodiment, the wire-end mechanical connection part 11 may further include a rubber plug 112 disposed in the mounting cavity for firmly pressing the fixing seat 111, the rubber plug 112 having a through-hole for the wire-end electrical connection part 12 and the first connecting cable 4 to pass through. The design of the rubber plug 112 makes the fixing seat 111 more stable and reliable after being inserted into the mounting cavity, and the rubber plug 112 can also provide a certain protection for the wire-end electrical connection part 12 and the first connecting cable 4.

[0048] The present disclosure also provides an electrical device including a wiring connector, the wiring connector being the wiring connector described in any of the above solutions. Since the wiring connector has the above technical effects, an electrical device having the wiring connector should also have corresponding technical effects, and no further details will be provided here.

[0049] In addition, each embodiment in this specification is described progressively, and the focus of each embodiment is on the differences from other embodiments, and the same or similar parts between each embodiment may be referred to each other.

[0050] It is understood that in this disclosure, the use of "system," "apparatus," "means," and / or "module" is merely a way to distinguish between different units, elements, components, parts, or assemblies at different levels. However, other expressions can be used in place of the words if they can achieve the same purpose.

[0051] As used herein and in the claims, unless the context clearly dictates otherwise, words such as "a," "one," "an," and / or "the" do not specifically refer to the singular but may include the plural. Generally, the terms "comprise" and "containing" merely indicate the inclusion of explicitly identified steps and elements; these steps and elements are not an exclusive list; a method or apparatus may also include other steps or elements. An element qualified by the phrase "comprises one of..." does not exclude the presence of additional identical elements in the process, method, product, or apparatus that includes the element.
