Description

Technical Field

[0001] This invention relates to the field of signal transmission technology, and more particularly to a controller output board connector. Background Technology

[0002] As the core control component of two-wheeled vehicles, three-wheeled vehicles, and various electronic and electrical equipment, the controller needs to be electrically connected to the motor, power supply, and signal harness through connectors in order to transmit power and control signals.

[0003] Currently, most common controller wiring structures employ a wire harness approach, where one end of multiple wires is soldered to the circuit board inside the controller, and the other end extends from the controller housing, connecting to external devices via individual connectors. For example, Bosch Automotive Components (Suzhou) Co., Ltd.'s 2011 patent, "Connector Assembly for Electronic Control Units of Electric Bicycles" (CN202042769U), uses a male connector on the electronic control unit and a female connector connecting the wire harness. In addition, multi-connector solutions that separate power and signal transmission exist on the market, used separately for motor power lines and signal lines.

[0004] However, the existing controller output board connectors have technical problems such as loose structure and complicated assembly. Summary of the Invention

[0005] The purpose of this invention is to provide a solution to the technical problem of loose structure and complex assembly of the controller output board connector in the prior art.

[0006] In a first aspect, the present invention provides a controller output board connector, comprising: A board-end housing for fixing to a controller, wherein the board-end housing has at least one power terminal mounting hole and at least one signal terminal mounting hole inside; At least one power terminal, said power terminal being fixed in said power terminal mounting hole, one end of which is used for electrical connection to the controller circuit board; At least one signal terminal is fixed in the signal terminal mounting hole, and one end of the signal terminal is used for electrical connection with the controller circuit board. A wire connector is pluggably mated to the board housing, and has inside a power pin terminal that mates with the power terminal and a signal pin terminal that mates with the signal terminal. A locking structure is provided between the plate end housing and the wire end connector for locking and fixing them after they are inserted.

[0007] Furthermore, the locking structure includes an elastic latching arm disposed on the plate end housing and a locking boss disposed on the wire end connector; when the wire end connector and the plate end housing are inserted into place, the elastic latching arm engages with the locking boss.

[0008] Furthermore, an annular groove is provided on the outer side of the mating end face of the plate end housing, and an elastic waterproof ring is embedded in the annular groove; when the wire end connector is inserted into the plate end housing, the inner wall of the wire end connector is interference-fitted with the elastic waterproof ring.

[0009] Furthermore, the inner diameter of the power terminal mounting hole is larger than the inner diameter of the signal terminal mounting hole, and the outer diameter of the power terminal is larger than the outer diameter of the signal terminal.

[0010] Furthermore, there are multiple signal terminal mounting holes, and the cross-sectional shapes of the multiple signal terminal mounting holes are different from each other; the cross-sectional shape of the signal pin terminal matches the cross-sectional shape of the corresponding signal terminal mounting hole.

[0011] Furthermore, both the power supply terminal and the signal terminal are through-hole terminals, with the end facing the controller circuit board being a soldered end.

[0012] Furthermore, the plate end housing is an integral injection molded structure made of thermoplastic polyester elastomer; the power terminal and the signal terminal are externally covered with positioning parts made of glass fiber reinforced polyamide engineering plastic.

[0013] Compared with the prior art, the present invention provides a controller output board connector, comprising a board housing, at least one power terminal, at least one signal terminal, a wire connector, and a locking structure; the board housing is used to fix to the controller, and has at least one power terminal mounting hole and at least one signal terminal mounting hole inside; the power terminal is fixed in the power terminal mounting hole, and one end of it is used for electrical connection with the controller circuit board; the signal terminal is fixed in the signal terminal mounting hole, and one end of it is used for electrical connection with the controller circuit board; the wire connector is pluggably mated to the board housing, and has a power pin terminal that mates with the power terminal and a signal pin terminal that mates with the signal terminal; the locking structure is provided. Located between the board housing and the wire connector, this structure locks and secures the board after they are mated. By integrating the power terminals and signal terminals into the same board housing and directly fixing the board housing to the controller, it replaces the traditional wire harness structure with multiple wires leading out separately, avoiding the problem of messy and loose wire harnesses and making the overall controller structure more compact and concise. At the same time, by setting a locking structure between the board housing and the wire connector, quick locking and securing are achieved after mating, effectively preventing the connection from loosening due to vibration or pulling, and significantly improving the reliability and safety of the connection. In addition, this structure facilitates automated welding and assembly of the board during the controller production process, simplifying the assembly process and improving production efficiency.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. These terms are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element 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 the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figures 1 to 3 As shown, this embodiment provides a controller output board connector, including a board housing 100, power terminals (not shown in the figure), signal terminals (not shown in the figure), a wire connector 200, and a locking structure.

[0025] Please refer to Figure 1 and Figure 2 The plate-end housing 100 is used to fix it to the controller (not shown in the figure). Specifically, the plate-end housing 100 can be fixed to the controller's housing by means of snap-fit, threaded connection, or integral molding, so as to facilitate assembly and fixation. The plate-end housing 100 has at least one power terminal mounting hole 110 and at least one signal terminal mounting hole 120 inside. The power terminal mounting hole 110 is used to receive and fix the power terminal, and the signal terminal mounting hole 120 is used to receive and fix the signal terminal. As a preferred embodiment, the plate-end housing 100 adopts an integral injection molded structure, and its material is thermoplastic polyester elastomer (such as TPEE95). This material has good elasticity, processability and electrical insulation properties, which facilitates injection molding and ensures the flexibility and durability of the housing.

[0026] A power terminal (not shown in the figure) is fixed inside the power terminal mounting hole 110, with one end used for electrical connection to the controller circuit board (not shown in the figure). Specifically, one end of the power terminal extends into the controller and is electrically connected to the power output point on the controller circuit board by soldering; the other end of the power terminal extends to the mating end face of the board end housing 100 for insertion and mating with the power pin terminal in the wire connector 200. The power terminal is made of a metal material with good conductivity, such as copper alloy, and the surface can be tin-plated or gold-plated to improve conductivity and oxidation resistance.

[0027] The signal terminal (not shown in the figure) is fixed inside the signal terminal mounting hole 120, with one end used for electrical connection to the controller circuit board. Similar to the power terminal, one end of the signal terminal extends into the controller and is electrically connected to the signal output point on the controller circuit board by soldering; the other end of the signal terminal extends to the mating end face of the board end housing 100 for insertion and mating with the signal pin terminal in the wire connector 200. The signal terminal is also made of a metal material with good conductivity.

[0028] Please refer to Figure 1The wire connector 200 is pluggably mated to the board housing 100. The wire connector 200 internally has a power pin terminal (not shown) that mates with the power terminal, and a signal pin terminal (not shown) that mates with the signal terminal. The power pin terminal and signal pin terminal are electrically connected to external motor wires, power lines, or signal lines, respectively. When the wire connector 200 is mated to the board housing 100, the power terminal and the power pin terminal are connected, and the signal terminal and the signal pin terminal are connected, thereby achieving electrical connection between the controller and external devices.

[0029] Please refer to Figure 3 A locking structure is disposed between the plate end housing 100 and the wire end connector 200 to lock and fix them after they are inserted, preventing the connection from loosening due to vibration or external pulling. In a specific embodiment of the invention, the locking structure includes an elastic latching arm 310 disposed on the plate end housing 100 and a locking boss 320 disposed on the wire end connector 200. The elastic latching arm 310 has a certain elastic deformation capability. When the wire end connector 200 is inserted into the plate end housing 100, the elastic latching arm 310 is elastically opened outward under force during insertion. After insertion, the elastic latching arm 310 springs back to its original position and locks into the locking boss 320, thereby locking and fixing the two. When disassembly is required, pressing the elastic latching arm 310 to disengage it from the locking boss 320 allows the wire end connector 200 to be pulled out of the plate end housing 100. This latching locking structure is simple and reasonable, easy to operate, and reliable in locking.

[0030] To further enhance the practicality of the present invention, this embodiment also provides the following preferred structure: Preferably, such as Figure 3 As shown, the locking structure includes a resilient latching arm 310 disposed on the plate end housing 100 and a locking boss 320 disposed on the wire end connector 200. The resilient latching arm 310 is integrally formed with the plate end housing 100, and the locking boss 320 is integrally formed with the wire end connector 200, which ensures structural strength and facilitates manufacturing. When the wire end connector 200 and the plate end housing 100 are inserted into place, the resilient latching arm 310 engages with the locking boss 320 to achieve locking.

[0031] Preferably, such as Figure 2As shown, the outer side of the mating end face of the board end housing 100 is provided with an annular groove (not shown in the figure), and an elastic waterproof ring (not shown in the figure) is embedded in the annular groove. The elastic waterproof ring is made of elastic materials such as rubber or silicone. When the wire end connector 200 is inserted into the board end housing 100, the inner wall of the wire end connector 200 and the elastic waterproof ring form an interference fit, thereby forming a seal between them and effectively preventing moisture and dust from entering the connector. Through this structural design, the present invention can achieve the IPX7 waterproof level requirement and is suitable for humid environments such as electric vehicles and outdoor electrical appliances.

[0032] Preferably, such as Figure 2 As shown, the inner diameter of the power terminal mounting hole 110 is larger than the inner diameter of the signal terminal mounting hole 120, and correspondingly, the outer diameter of the power terminal is larger than the outer diameter of the signal terminal. This dimensional difference design achieves a foolproof function for the power and signal terminals, preventing operators from confusing the power terminals and signal terminals during insertion, and improving the accuracy and safety of assembly.

[0033] Preferably, such as Figure 2 As shown, when there are multiple signal terminal mounting holes 120, the cross-sectional shapes of the multiple signal terminal mounting holes 120 are set to be different, such as circular, square, elliptical, triangular, etc. Correspondingly, the cross-sectional shape of the signal pin terminal matches the cross-sectional shape of the corresponding signal terminal mounting hole 120. This non-recognizable design can effectively prevent incorrect insertion between multiple signal terminals, ensuring that each signal terminal can only be correctly inserted with the corresponding signal pin terminal, thus improving the reliability of signal transmission.

[0034] Preferably, both the power supply terminals and signal terminals are through-hole terminals, with the end facing the controller circuit board being the soldering end. This through-hole structure facilitates rapid soldering to the circuit board on automated production lines using methods such as wave soldering or reflow soldering, improving production efficiency, reducing labor costs, and ensuring the stability and reliability of soldering quality.

[0035] Preferably, the plate end housing 100 adopts an integral injection-molded structure, and its material is thermoplastic polyester elastomer (such as TPEE95), which has good elasticity, processability, and electrical insulation. The power terminals and signal terminals are externally covered with positioning elements made of glass fiber reinforced polyamide engineering plastic (such as DSM PA46 GF33). These positioning elements are injection-molded onto the outside of the terminals to fix their positions and ensure the insulation distance between them. PA46 GF33 material has high heat resistance, high crystallinity, and excellent mechanical strength, enabling it to maintain dimensional stability during high-temperature welding and long-term use, ensuring terminal position accuracy.

[0036] In summary, the controller output board connector provided in this embodiment of the invention integrates the power terminals and signal terminals within the same board housing, replacing the traditional multi-wire lead-out structure, making the overall controller structure more compact and concise. A snap-lock structure enables quick locking and disassembly, preventing loosening. An elastic waterproof ring ensures reliable waterproof sealing. Different terminal sizes and irregular shapes prevent incorrect insertion. The use of high-performance engineering plastics guarantees the product's heat resistance, mechanical strength, and long-term reliability. This connector features a simple structure, convenient assembly, reliable connection, and good waterproof performance, making it suitable for widespread application in electric vehicles, outdoor electrical appliances, and other similar equipment.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
