Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an integrated connector assembly for a fan controller. Background Technology

[0002] The wind turbine controller is a key component of a wind power generation system. Its function is to regulate the operating status of the wind turbine to optimize wind energy capture and power generation efficiency.

[0003] During the plug-in and unplugging process of the fan controller of a brushless blower (BLDC), abnormal discharge often occurs due to unstable connection, which in turn impacts the components of the fan controller and affects the service life and stability of the brushless blower. This is especially true when used in automotive electrical systems, where it can easily lead to vehicle malfunctions or even accidents.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a wind turbine controller integrated plug-in component to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention discloses an integrated plug-in assembly for a wind turbine controller, which reduces the probability of abnormal discharge and the impact on the wind turbine controller during the plug-in and unplugging process.

[0007] This utility model discloses an integrated plug-in assembly for a fan controller, including a controller mounting plate, on which a plug-in socket is provided, wherein:

[0008] The connector has a guide groove at its front end, within which positive, negative, control signal, and feedback terminals are spaced apart. The exposed length of the positive terminal is shorter than that of the negative terminal. During insertion, the negative terminal first makes an electrical connection with the connector, allowing the arc to be discharged promptly in case of abnormal discharge, reducing the impact on the fan controller. The exposed length of the negative terminal is shorter than the depth of the guide groove, ensuring that the connector passes through the guide groove to correct its orientation before making circuit connections, thus preventing abnormal discharges caused by incorrect insertion direction.

[0009] Preferred technical solution: The exposed length of the positive electrode plug is 0.5mm-1mm shorter than that of the negative electrode plug, so that the negative electrode plug can be electrically connected to the connector first without affecting the stability of the connection between the connector and the socket.

[0010] Preferred technical solution: The socket is provided with a pluggable connector. The outer periphery of the connector is consistent with the shape and size of the guide groove, so that the connector is aligned with the socket during insertion and removal. The front end of the connector is provided with insertion holes corresponding to the positive terminal, negative terminal, control signal terminal and feedback terminal respectively.

[0011] Preferred technical solution: The bottom of the guide slide is provided with mounting through holes corresponding to the insertion holes. The side wall of the mounting through holes is provided with a snap-fit ​​platform. The positive electrode insert, negative electrode insert, control signal insert and feedback insert are all provided with a continuous tooth structure for docking with the snap-fit ​​platform, which facilitates the installation of the inserts and precise control of the exposed length of the inserts in the guide slide.

[0012] Preferred technical solution: The mounting through hole is also provided with a vent groove that runs through the bottom of the guide slide to balance the air pressure between the guide slide and the outside, and to prevent the connector from locking up due to the difference in air pressure inside and outside when it moves in the guide slide.

[0013] Preferred technical solution: The outer periphery of the connector is also provided with a through groove to balance the air pressure between the guide slide and the outside, and to prevent the connector from locking up due to the difference in air pressure inside and outside when it moves in the guide slide.

[0014] Preferred technical solution: The rear ends of the positive electrode plug, negative electrode plug, control signal plug, and feedback plug are all vertically inserted and fixed on the controller mounting plate to improve connection stability.

[0015] Preferred technical solution: The side wall of the guide slide is provided with a vent hole, one side of which extends to the bottom of the guide slide to avoid forming a closed air cavity when the connector and the connector seat are inserted, thus preventing them from being blocked from insertion and removal.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model's integrated plug-in assembly for a fan controller are as follows:

[0017] (1) By using the difference in exposed length between the positive and negative terminals, the negative terminal is connected to the circuit first, and then the positive terminal is connected to form a complete circuit. Before connecting the positive terminal, it is ensured that these devices will not be accidentally powered on, thus avoiding the risk of short circuit and preventing dangerous situations such as sparks, battery damage, or even fire that may result, thereby improving the safety of using the brushless blower.

[0018] (2) Prioritizing contact with the negative electrode can better protect the circuit. Abnormal discharges such as static electricity at the connection point are first discharged through the negative electrode circuit, and then connected to the positive electrode to form a loop. This prevents abnormal discharges from interfering with normal current transmission, reduces damage and impact caused by static discharge, and improves the service life of the fan controller. It has a good effect on the protection of precision instruments. Especially when applied to automotive electrical systems, it helps to ensure the normal operation of automotive electrical systems and reduce vehicle malfunctions or accidents caused by circuit faults.

[0019] (3) By increasing the length of the guide groove, the direction of the connector is corrected before it is connected to the connector plate, so as to avoid abnormal discharge caused by contact direction or shaking between the plate and the connector hole. Attached Figure Description

[0029] Example 1:

[0030] like Figure 1 As shown, this utility model discloses an integrated plug-in assembly for a fan controller, including a controller mounting plate 1. A plug-in socket 2 is fixedly disposed on the upper side of the controller mounting plate 1, and a plug connector 3 is detachably disposed within the plug-in socket 2. The main components of this utility model will be described in detail below:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the front end of the connector 2 is provided with a guide groove 21 for directional correction of the connector 3. The bottom of the guide groove 21 has four spaced mounting through holes 21b. The sidewalls of the mounting through holes 21b are provided with a snap-fit ​​platform 21c and a vent groove 21d penetrating the bottom of the guide groove 21. The mounting through holes 21b are provided with a positive electrode insert 22, a negative electrode insert 23, a control signal insert 24, and a feedback insert 25. All 5 are fixed to the mounting plate 21c by a continuous toothed structure; the rear ends of the positive electrode plug 22, negative electrode plug 23, control signal plug 24 and feedback plug 25 are all vertically inserted and fixed on the controller mounting plate 1; the exposed length of the positive electrode plug 22 is 0.5mm-1mm shorter than that of the negative electrode plug 23; the exposed length of the negative electrode plug 23 is less than the depth of the guide groove 21; the side wall of the guide groove 21 is provided with a vent hole 21a, and one side of the vent hole 21a extends to the bottom of the guide groove 21.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the outer periphery shape and size of the connector 3 are consistent with the shape and size of the guide groove 21. The front end of the connector 3 is provided with a plug hole 31 corresponding to the positive electrode plug 22, the negative electrode plug 23, the control signal plug 24 and the feedback plug 25 respectively. The outer periphery of the connector 3 is also provided with a through groove 32.

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the principle of the integrated plug-in assembly for a fan controller according to this utility model is as follows: The exposed length of the positive plug 22 is 0.5mm-1mm shorter than that of the negative plug 23. During plugging, the negative plug 23 is connected to the circuit first, followed by the positive plug 22 to form a complete circuit. In this process, if discharge occurs, it will be buffered by the already connected negative plug 23, reducing the impact on the components on the controller mounting plate 1, thus protecting them from damage caused by current surges and improving safety. Simultaneously, connecting the negative circuit first allows static electricity at the connector to be discharged through the negative circuit, preventing electrostatic discharge from affecting the circuit loop. This enhances the stability and reliability of the circuit. Increasing the depth of the guide groove 21 and using it to restrict the plug-in movement trajectory of the connector 3 prevents shaking or misalignment during plugging, thereby reducing the probability of abnormal discharge.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
