Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a terminal block and an electric vehicle controller. Background Technology

[0002] To facilitate regulated travel, electric bicycles are evolving towards miniaturization, lightweight design, and high performance. The electric bicycle controller is used to control the start, operation, forward and reverse movement, speed, and stop of the electric bicycle motor, as well as other electronic components. It is the core control device on the electric bicycle, responsible for coordinating the operation of the entire electric bicycle system. During the manufacturing process of the electric bicycle controller, the sealing and waterproofing performance of the wiring terminals are crucial.

[0003] In existing technologies, the sealing of wiring terminals in electric vehicle controllers typically involves applying adhesive first and then soldering. This means applying adhesive to both the wiring terminals and the controller top cover, and then soldering the terminals to the circuit board located between the top cover and the base. However, this method is prone to sealant failure due to the high temperatures during soldering, affecting the sealing performance of the wiring terminals. This not only impacts the lifespan and safety of the wiring terminals but also poses a potential risk to the overall performance of the electric bicycle. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the sealant produced when using wiring terminals in electric vehicle controllers in the prior art is prone to failure, thereby affecting the sealing performance, service life and safety of the wiring terminals, and to provide a wiring terminal and electric vehicle controller.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A terminal block includes a mounting housing. The mounting housing has the following structure: it includes a housing, at least one receiving groove is formed on the top of the housing, and at least one dispensing groove is formed on the side of the housing. The dispensing groove and the receiving groove are arranged in a one-to-one correspondence. A first through hole and a second through hole are respectively formed on the two opposite side walls of a single dispensing groove. A conductive sheet is installed in a single first through hole and a corresponding second through hole.

[0007] Adhesive is injected between the corresponding conductive sheet and the housing through the dispensing groove, thereby filling the gap between the conductive sheet and the housing and achieving a sealed installation between the conductive sheet and the housing.

[0008] As a further improvement to the above technical solution:

[0009] The structure of a single conductive sheet is as follows: it includes a first plug segment and a second plug segment arranged parallel to the first plug segment. One end of the first plug segment and one end of the second plug segment are simultaneously connected to the first connecting segment. The end face normal of the first connecting segment is perpendicular to the end face normal of the first plug segment. The other end of the second plug segment is connected to the second connecting segment. The second connecting segment is arranged parallel to the first connecting segment.

[0010] In a single conductive sheet, a flow hole is formed on the end face of the second insertion segment.

[0011] When a single conductive sheet is mounted on the mounting housing, the dispensing hole is located in the corresponding dispensing groove.

[0012] A mounting slot is provided on the housing next to a single receiving slot, which is used to mate with the first plug segment of the corresponding conductive sheet for installation.

[0013] A connecting nut is installed in a single receiving slot, and the connecting nut supports the first connecting segment of the corresponding conductive sheet.

[0014] A center hole is provided in the middle of each connecting nut.

[0015] In a single conductive sheet, a connection hole is formed on the end face of the first connecting segment.

[0016] In a single conductive sheet, several limiting blocks are respectively provided on both sides of the second plug segment.

[0017] An electric vehicle controller includes a base and a top cover that are installed together. A control module is installed between the base and the top cover. The aforementioned wiring terminals are installed on the top cover. Adhesive is injected between the wiring terminals and the top cover through an adhesive dispensing groove, thereby filling the gap between the wiring terminals and the top cover and achieving a sealed installation between the wiring terminals and the top cover.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model has a compact and reasonable structure and is easy to operate. By setting up a mounting shell with a dispensing groove and a conductive sheet, after the wiring terminals are soldered onto the circuit board, glue can be easily dispensed between the mounting shell and the conductive sheet, and between the wiring terminals and the top cover through the dispensing groove. This avoids the high temperature during soldering affecting the adhesive performance, extends the service life of the wiring terminals, improves the safety of the wiring terminals, effectively improves the sealing and waterproof performance of the electric vehicle controller, and ensures the overall performance of the electric bicycle.

[0020] This utility model also has the following advantages:

[0021] (1) By setting the dispensing orifice, the generation of air bubbles during the dispensing process can be effectively reduced.

[0022] (2) By setting the mounting slot, the first plug segment can be inserted into the corresponding mounting slot, which can improve the installation stability between the corresponding conductive sheet and the mounting shell.

[0023] (3) By setting a connecting nut, the installation stability between the corresponding conductive sheet and the mounting shell can be further improved.

[0024] (4) By setting a limit block, the second insertion section of the conductive sheet can be prevented from shaking in the first through hole, thereby improving the structural stability of the terminal block. Attached Figure Description

[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0038] The structure and function of this utility model are as follows:

[0039] like Figures 1-7 As shown, a terminal block includes a mounting housing 1. The mounting housing 1 has the following structure: a housing 101, at least one receiving groove 103 is formed on the top of the housing 101, and at least one dispensing groove 102 is formed on the side of the housing 101. The dispensing groove 102 and the receiving groove 103 are arranged in a one-to-one correspondence. A first through hole 106 and a second through hole 107 are respectively formed on the opposite side walls of a single dispensing groove 102. A conductive sheet 3 is installed in both the first through hole 106 and the corresponding second through hole 107. Adhesive is injected between the corresponding conductive sheet 3 and the housing 101 through the dispensing groove 102, so that the adhesive fills the gap between the corresponding conductive sheet 3 and the housing 101, thereby achieving a sealed installation between the conductive sheet 3 and the housing 101. By setting up a mounting shell 1 with a dispensing groove 102 and a conductive sheet 3, after the terminal is soldered onto the circuit board, adhesive can be easily dispensed between the mounting shell 1 and the conductive sheet 3 through the dispensing groove 102, thereby avoiding the high temperature during soldering from affecting the bonding performance between the mounting shell 1 and the conductive sheet 3, and effectively improving the sealing and waterproof performance of the terminal.

[0040] The structure of a single conductive sheet 3 includes a first insertion segment 301 and a second insertion segment 302 arranged parallel to the first insertion segment 301. One end of the first insertion segment 301 and one end of the second insertion segment 302 are simultaneously connected to a first connecting segment 303. The normal to the end face of the first connecting segment 303 is perpendicular to the normal to the end face of the first insertion segment 301. The other end of the second insertion segment 302 is connected to a second connecting segment 304, which is arranged parallel to the first connecting segment 303. The conductive sheet 3 is used to realize point connections between the circuit board and the wires, and the second connecting segment 304 is used to mount the circuit board, thereby realizing electrical signal transmission.

[0041] In a single conductive sheet 3, a dispensing hole 306 is formed on the end face of the second insertion section 302; when the single conductive sheet 3 is mounted on the mounting housing 1, the dispensing hole 306 is located in the corresponding dispensing groove 102. By setting the dispensing hole 306, the generation of air bubbles during the dispensing process can be effectively reduced.

[0042] A mounting groove 105 is provided on the housing 101 next to the individual receiving groove 103. The mounting groove 105 is used to mate with the first insertion segment 301 of the corresponding conductive sheet 3 for installation. By inserting the first insertion segment 301 into the corresponding mounting groove 105, the installation stability between the corresponding conductive sheet 3 and the mounting housing 1 can be improved.

[0043] A connecting nut 2 is installed in a single receiving slot 103, and the connecting nut 2 supports the first connecting segment 303 of the corresponding conductive sheet 3. By setting the connecting nut 2, the installation stability between the corresponding conductive sheet 3 and the mounting shell 1 can be further improved.

[0044] A central hole 4 is formed in the middle of a single connecting nut 2. A connecting hole 305 is formed on the end face of the first connecting segment 303 in a single conductive piece 3. A connecting groove 104 is formed on the bottom wall of a single receiving groove 103. The central hole 4, the connecting hole 305 and the connecting groove 104 correspond one-to-one and are arranged concentrically. By passing an external bolt through the connecting hole 305, the corresponding central hole 4 and the corresponding connecting groove 104 in sequence, the end of the wire is fixed to the surface of the first connecting segment 303, thereby realizing the electrical connection between the corresponding conductive piece 3 and the wire.

[0045] In a single conductive sheet 3, several limiting blocks 307 are respectively provided on both sides of the second insertion segment 302. By setting the limiting blocks 307, the second insertion segment 302 of the conductive sheet 3 can be prevented from shaking within the first through hole 306, thereby improving the structural stability of the terminal block.

[0046] In addition, several ventilation grooves 10 are provided in a single first through hole 106, which can accelerate the curing of the adhesive in the corresponding dispensing groove 102 and receiving groove 103.

[0047] like Figures 8-9 As shown, an electric vehicle controller includes a base 5 and a top cover 6 that are installed together. A control module is installed between the base 5 and the top cover 6. The aforementioned wiring terminals are installed on the top cover 6. Adhesive is injected between the wiring terminals and the top cover 6 through an adhesive dispensing groove 102, thereby filling the gap between the wiring terminals and the top cover 6 and achieving a sealed installation. In this invention, the control module includes a circuit board and several control components. The control module is used for converting and transmitting electrical signals, thereby controlling the movement of the electric bicycle.

[0048] like Figure 9 As shown, a glue gun is inserted into the gap formed between the outer wall of the terminal housing 101 and the outer wall of the top cover 6, and the tip of the glue gun is aligned with the glue dispensing groove 102, so that glue can be injected into the glue dispensing groove 102, thereby achieving a seal between the terminal and the top cover 6.

[0049] The installation process of this utility model is as follows:

[0050] A connecting nut 2 is embedded in a receiving groove 103, and the second insertion section 302 of a conductive sheet 3 is simultaneously inserted into the corresponding first through hole 106 and second through hole 107, so that the glue flow hole 306 on the second insertion section 302 is located in the glue dispensing groove 302.

[0051] The conductive sheet 3 is bent to form a first connecting segment 303, so that the first connecting segment 303 of the conductive sheet 3 fits against the top end face of the connecting nut 2, and ensures that the connecting hole 305, the center hole 4 and the connecting groove 104 are all aligned.

[0052] The conductive sheet 3 is then bent to form the first insertion segment 301, and the first insertion segment 301 is inserted into the corresponding mounting slot 105.

[0053] Finally, the conductive sheet 3 is bent to form the second connecting section 304. The second connecting section 304 is fixed to the circuit board by welding, thereby realizing the electrical connection between the circuit board and the terminal block. Then, glue is applied to the terminal block through the glue dispensing groove 102, so that the glue fills the gap between the conductive sheet 3 and the mounting shell 1. Finally, the glue is made to fill the glue dispensing groove 102, thereby wrapping the conductive sheet 3 in the glue dispensing groove 102 to ensure the sealing performance of the terminal block.

[0054] By using bolts to pass through the connecting hole 305, the corresponding center hole 4, and the corresponding connecting groove 104 simultaneously, the wire is crimped onto the first connecting section 301, thereby achieving electrical connection between the terminal block and the wire, and further achieving electrical connection between the wire and the circuit board.
