Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electric vehicle controller components, specifically to a conductive post structure for an electric vehicle controller. Background Technology
[0002] The electric vehicle controller is a very important component of an electric vehicle. It is the core control device used to control the starting, running, forward and backward movement, speed, and stopping of the electric vehicle motor, as well as other electronic devices in the electric vehicle.
[0003] Currently, the conductive posts on the market come in T-shaped, L-shaped, and cylindrical shapes. The top of the conductive post is fastened to the external power supply or motor terminal with screws; the bottom of the conductive post connects to the internal control board of the controller, and the connection methods are as follows:
[0004] T-shaped and L-shaped conductive posts are secured to the control board with two or more screws, and can also be soldered to the control board at the same time; cylindrical conductive posts are often connected to the circuit board with a single screw, and can also be soldered to the circuit board at the same time.
[0005] Due to the high cost of processing and materials for L-type and T-type terminals, and the fact that installation requires two or more screws to connect to the control board, the processing technology is complex.
[0006] When installing motor or power terminals on top of cylindrical conductive posts, the controller is usually connected to the motor or power line using terminals and bolts. However, since there is no circumferential limit on the circumference of the cylindrical conductive post when screws are screwed into the screw hole, the conductive post structure will rotate with the screw. This may cause the connection between the bottom of the cylindrical conductive post and the circuit board to loosen, and may tear the conductive copper foil on the control board, resulting in poor contact or open circuit, causing damage to the controller. Therefore, we propose a conductive post structure for electric vehicle controllers. Utility Model Content
[0007] To address the problems in the existing technology, this utility model provides a conductive post structure for an electric vehicle controller.
[0008] The technical solution adopted by this utility model to solve its technical problem is a conductive column structure for an electric vehicle controller, including a controller cover. Multiple limiting holes are opened at the center of the top of the controller cover. A dust cover is connected to the top of the limiting hole. An installation clip is fixedly connected to the inner wall of the limiting hole. The limiting hole is connected to a conductive column. The cross-section of the conductive column is polygonal, and the shape of the limiting hole matches that of the conductive column.
[0009] By adopting the above technical solution, during installation, the conductive column passes through the limiting hole, the bottom of the conductive column is connected to the control board inside the controller, and the top of the conductive column is connected to the wiring terminals of the motor and power cord by screws.
[0010] During installation and connection, the limiting hole structure on the controller cover restricts the rotation of the conductive post, thereby preventing the connection between the conductive post and the internal control board of the controller from becoming loose or the conductive post from sliding relative to the internal control board due to external force rotation, which could cause the copper foil of the internal control board of the controller to tear, resulting in poor contact or even open circuit in the connection circuit.
[0011] During installation, the fastening bolts are aligned with the mounting screw holes and tightened. When tightening the bolts, the connecting conductive post will not rotate with the screws due to the limiting action of the limiting hole on the controller cover. Compared with the traditional T-shaped, L-shaped, and cylindrical terminal block installation methods, this saves costs and improves installation efficiency.
[0012] Specifically, the surface of the controller cover has signal line openings. The outer periphery of the controller cover has multiple screw mounting holes for fixing.
[0013] By adopting the above technical solution, the screws, along with the motor or power supply terminals, are aligned with the conductive post mounting holes and screwed in to complete the installation.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] By adopting the above technical solution, during installation, the conductive column passes through the limiting hole, the bottom of the conductive column is connected to the control board inside the controller, and the top of the conductive column is connected to the wiring terminals of the motor and power cord by screws.
[0016] During installation and connection, the limiting hole structure on the controller cover restricts the rotation of the conductive post, thereby preventing the connection between the conductive post and the internal control board of the controller from becoming loose or the conductive post from sliding relative to the internal control board due to external force rotation, which could cause the copper foil of the internal control board of the controller to tear, resulting in poor contact or even open circuit in the connection circuit.
[0017] During installation, the fastening bolts are aligned with the mounting screw holes and tightened. When tightening the bolts, the connecting conductive post will not rotate with the screws due to the limiting action of the limiting hole on the controller cover. Compared with the traditional T-shaped, L-shaped, and cylindrical terminal block installation methods, this saves costs and improves installation efficiency. Attached Figure Description

[0025] Please see Figure 1-3 This utility model provides a technical solution: a conductive post structure for an electric vehicle controller, including a controller cover 1. The top of the controller cover 1 has a plurality of limiting holes 2 at its center. The top of the limiting holes 2 is connected to a dust cover 3.

The cross-section of the conductive posts 4 is polygonal, and the shape of the limiting holes 2 matches that of the conductive posts 4.
[0026] In use, the bottom of the connecting conductive post 4 is connected to the control board inside the controller, and the upper part of the conductive post passes into each limiting hole 2 and is connected to the wiring terminals on the motor and power supply. When the screw is tightened, the connecting conductive post 4 will not rotate with the screw due to the limiting action of the limiting hole 2 on the controller cover 1. Compared with the screw holes used for fixing with bolt fixing holes, it saves costs and improves installation efficiency.
[0027] Specifically, the surface of the controller cover 1 has a signal line opening 6.
[0028] Specifically, the outer periphery of the controller cover 1 is provided with multiple screw mounting holes 7 for fixing.

[0030] The working principle and usage process of this utility model are as follows: The bottom of the connecting conductive post 4 is connected to the control board inside the controller. The upper part of the conductive post passes through each limiting hole 2 of the controller cover 1 and is connected to the wiring terminals on the motor and power supply. When the screw is tightened, the connecting conductive post 4 will not rotate with the screw due to the limiting action of the limiting hole 2 of the controller cover 1. Compared with the use of L-shaped, T-shaped and circular conductive posts, this method improves safety, saves costs and improves installation efficiency.
