Description

Technical Field

[0001] This application relates to the field of testing new energy motor controllers, and in particular to an electrical connector and motor controller with a foolproof function. Background Technology

[0002] In the field of new energy vehicles, the motor controller is a key core component. Before it is assembled with the motor and installed in the vehicle, it must undergo a strict factory (off-line) testing process to verify its functional integrity and quality standards.

[0003] Before testing the motor controller, the positive and negative busbars and the UWV three-phase lines must be connected to the testing equipment. This connection process is time-consuming and inefficient. Furthermore, errors such as reversed positive and negative connections, reversed three-phase sequence, and mixed positive and negative connections with the three phases can occur. These issues not only affect production efficiency but also pose safety hazards during testing, such as short circuits or product explosions.

[0004] In view of this, there is an urgent need to provide an electrical connector that can constrain and identify cables with different phase sequences in order to reduce the occurrence of connection errors. Summary of the Invention

[0005] The purpose of this application is to provide an electrical connector and motor controller with a foolproof function, which can effectively prevent incorrect or reversed connection when the motor controller is connected to the test equipment.

[0006] Firstly, the electrical connector with foolproof function provided in this application adopts the following technical solution:

[0007] An electrical connector with foolproof function, comprising:

[0008] Insulating protective housing;

[0009] A contoured boss protrudes from one end of the insulating protective shell;

[0010] Multiple adapter bars are provided, with the insulating protective shell covering the waist of the multiple adapter bars so that both ends of the adapter bars extend out of the insulating protective shell. Each end of the adapter bar has a connection hole for electrical connection to the product end and the equipment end, respectively.

[0011] Furthermore, the insulating protective shell is divided into multiple independent installation areas, and the multiple transition busbars are spaced apart and interspersed with the multiple independent installation areas one by one.

[0012] Furthermore, it also includes a limiting structure, which protrudes from the insulating protective shell and has multiple limiting holes for the adapter to extend out.

[0013] Furthermore, the insulating protective shell includes:

[0014] First shell;

[0015] The second housing is spliced ​​with the first housing to form multiple independent installation areas.

[0016] Furthermore, the insulating protective shell and the contoured boss are integrally formed.

[0017] Furthermore, the insulating protective shell is provided with a marking area.

[0018] Secondly, this application provides a motor controller that includes the aforementioned current connection connector.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By integrating multiple adapter bars into an insulated protective housing with a foolproof design, a standardized connection module is formed. During operation, simply force the foolproof structure (such as a contoured boss) to match the product interface outline; manual identification of cable phase sequence is unnecessary. Cables at the test equipment end can be pre-fixed to the device, forming a "plug-and-play" module. This improves production and testing efficiency and reduces installation error rates and equipment failure rates caused by installation errors.

[0021] 2. Based on physical error prevention mechanisms (contour matching + forced hole alignment) and electrical isolation design (independent installation area + copper busbar spacing control), the three main risks of reverse polarity connection, phase sequence error and phase-to-phase short circuit are eliminated from the source.

[0025] The following will be combined with the appendix Figure 1-2 The technical solution of this application is clearly and completely described. The following embodiments are exemplary and are only used to explain this application, and should not be construed as limiting this application. In the following description, the same reference numerals are used to denote the same or equivalent elements, and repeated descriptions are omitted.

They are only used to facilitate the description of this application and to simplify the description, and are not intended to indicate or imply that the equipment or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Furthermore, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] It should also be further understood that the term “and / or” as used in this application refers to any combination of one or more of the listed items, and all possible combinations thereof.

[0029] An electrical connector with foolproof function, as shown in the reference. Figure 1 and Figure 2 It includes an insulating protective shell 1, a contoured boss 2, and multiple adapter bars 3. The contoured boss 2 protrudes from one end of the insulating protective shell 1. The insulating protective shell 1 covers the waist of the multiple adapter bars 3 so that both ends of the adapter bars 3 extend out of the insulating protective shell 1. Both ends of the adapter bars 3 are provided with connection holes 31 for electrical connection to the product end and the equipment end, respectively.

[0030] It should be noted that this embodiment does not specifically limit the material of the adapter strip 3, as long as it can ensure that the electrical connection between the product and the testing equipment can be achieved through the electrical connector. For example, the adapter strip 3 can be made of copper, gold or silver.

[0031] The electrical connector serves as an intermediate structure, enabling electrical connection between the product and the testing equipment for product testing. During the electrical connection process, the testing equipment and the electrical connector are first connected together via cables, forming a single unit. The electrical connector is then connected to the product. A contoured boss 2 prevents incorrect or reversed installation during the connection process.

[0032] The contoured boss 2 prevents the connecting hole 31 on the adapter 3 from aligning with the screw hole on the product when it is misaligned or reversed, thus preventing the insertion of screws for fixing. When the contoured boss 2 is fully fitted with the product, the connecting hole 31 aligns with the screw hole on the product, and only then can the connector be fixed to the product with screws.

[0033] In this embodiment, the insulating protective shell 1 and the contoured boss 2 are integrally formed to enhance the overall strength of the contoured boss 2 and the insulating protective shell 1. In other embodiments, the contoured boss 2 can also be detachably set on the insulating protective shell 1. The size of the contoured boss 2 can be customized based on the interface of different products to enhance its versatility.

[0034] Furthermore, in other embodiments, a flexible protective layer may be applied to the end of the contoured boss 2 facing away from the insulating protective shell 1. When the contoured boss 2 is attached to the product, the flexible protective layer acts as a buffer to protect the interface between the contoured boss 2 and the product, reducing the possibility of poor docking accuracy caused by severe wear at the interface of the contoured boss 2 or the product during repeated docking processes.

[0035] Furthermore, the electrical connector also includes a limiting structure 4, which protrudes from the insulating protective shell 1 and has multiple limiting holes 41 for the adapter 3 to extend out.

[0036] The limiting structure 4 protects the portion of the adapter 3 extending from the insulating protective shell 1 while simultaneously facilitating precise docking with the electrical connector. Specifically, when the electrical connector docks with the product, the limiting structure 4 acts as a pilot part, first inserting into the corresponding hole on the product. When the limiting structure 4 is fully fitted with the product, it indicates that the electrical connector has been installed in place and can be fixed to the product.

[0037] Furthermore, the insulating protective housing 1 is divided into multiple independent installation areas, and multiple transition bars 3 are spaced apart and interspersed with the multiple independent installation areas one by one. The multiple independent installation areas are spaced apart between the multiple transition bars 3 to reduce the risk of electric arcing caused by adjacent transition bars 3 being too close together or coming into contact.

[0038] In one specific embodiment, there are two independent mounting areas and two adapter bars 3, whereby the electrical connectors act as positive and negative connectors to connect the product to the device under test. In another specific embodiment, there are three independent mounting areas and three adapter bars 3, whereby the electrical connectors act as three-phase connectors to connect the product to the device under test.

[0039] Correspondingly, refer to Figure 1 The insulating protective housing 1 is provided with a marking area 13, which can be marked to facilitate the wiring of the electrical connector to the device under test. Taking the electrical connector as a three-phase connector as an example, the marking area 13 is marked with the letters "U", "V" and "W" to indicate the connection of the cables to be connected to the terminal block, further ensuring that the operator can perform the installation correctly during operation.

[0040] Furthermore, the insulating protective shell 1 includes a first shell 11 and a second shell 12 spliced ​​with the first shell 11. When the first shell 11 and the second shell 12 are spliced ​​together, multiple independent installation areas are formed as described above. The splicing method facilitates the connection of the adapter 3 to the insulating protective shell 1.

[0041] It should be noted that this application does not specifically limit the connection form between the adapter bar 3 and the insulating protective shell 1. For example, in other embodiments, the connection method between the insulating protective shell 1 and the adapter bar 3 can also be plastic coating or injection molding.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
