Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted motors, in particular to a terminal structure that can be used for thermal riveting. Background Art

[0002] With the development of the economy, the automobile industry has developed rapidly. In order to ensure the power, economy and comfort performance requirements of automobiles, it is necessary to equip them with complete actuators. Therefore, various actuators with motors are widely used in various parts of automobiles.

[0003] In motor manufacturing applications, the electronic components of the motor controller need to be reliably connected to the busbar through terminal blocks to ensure efficient power transmission. Traditional busbars require welding the input and output wires of each winding, which is costly, complex, time-consuming, and requires increased reliability. Therefore, improvements are necessary. Utility Model Content

[0004] The utility model provides a terminal block structure that can be used for hot riveting, which is easy to process and manufacture, and the terminal block can be directly used for hot riveting, effectively simplifying the installation process and improving the installation efficiency, while ensuring that the electrical performance and mechanical strength of the connection meet the application requirements; it solves the technical problems in the prior art that the current terminal block structure is single, the input and output wires of each winding need to be welded, the processing time is long, the process is complicated, and the processing efficiency is low.

[0005] The above technical problem of the present invention is solved by the following technical solution: a terminal structure that can be used for heat riveting, including a heat riveting base, a heat riveting terminal provided on the heat riveting base, and the melting point of the heat riveting terminal is higher than the melting point of the heat riveting base; the heat riveting terminal and the heat riveting base are fixed by heat riveting, a riveting foot structure is provided at the bottom of the heat riveting terminal, a wire is fixed on the heat riveting base, and solder holes for soldering the wires are opened on both sides of the heat riveting terminal. During assembly, the heat riveting terminal is first heated by the heating head of the heat riveting equipment, and then pressure is applied to the heating head, so that the heat riveting terminal contacts the heat riveting base. Since the melting point of the heat riveting terminal is much higher than that of the heat riveting base, the heat riveting base softens after contact. As pressure is applied, the heat riveting terminal is embedded in the heat riveting base. During the heat riveting process, the softened heat riveting base is squeezed into the heat riveting terminal by the riveting foot structure, which can fix and seal the PCB. Finally, it solidifies and forms after cooling; and the wire and the heat riveting terminal can be soldered through the solder holes.

[0006] Preferably, the heat riveting base and the heat riveting terminal are made of different materials, and the heat riveting terminal has a higher melting point than the heat riveting base. To ensure that the heat riveting terminal does not deform during the heat riveting process, the heat riveting base and the heat riveting terminal in the present invention are made of different materials, and the melting point of the heat riveting terminal must be higher than that of the heat riveting base.

[0007] Preferably, the heat-riveted terminal is made of a high-temperature resistant material. The heat-riveted terminal of the present invention is made of a high-temperature resistant material, which can effectively ensure that the heat-riveted terminal will not soften or deform during the heat riveting process.

[0008] Preferably, the heat-riveted terminal is made of pure copper. Pure copper heat-riveted terminals have the advantages of a high melting point, good thermal conductivity, and good electrical conductivity. They heat up quickly during heat riveting and prevent deformation or softening, maintaining good physical and chemical properties.

[0009] Preferably, the heat riveting base is made of pps plastic. The melting point of the heat riveting base made of pps plastic is lower than that of the heat riveting terminal. The heat riveting base made of pps plastic has good thermoplasticity and excellent insulation performance, and is cooled and solidified after heat riveting to achieve final shape.

[0010] Preferably, the rivet foot structure is a smooth annular foot. The shape of the rivet structure can be adjusted according to actual needs. Different shapes of rivet foot structures have different effects during the hot riveting process. The present invention uses a smooth annular foot as an example to illustrate that the smooth annular foot can play a certain role in guiding the overflow of the hot riveting base after softening into the hot riveting terminal, thereby fixing and sealing the PCB.

[0011] Preferably, a high-melting-point conductive material is added to both the inner and outer surface coatings of the heat-riveted terminal. Adding a high-melting-point conductive material to the inner and outer surface coatings of the heat-riveted terminal can increase the corrosion resistance of the heat-riveted terminal and improve the contact resistance.

[0012] Preferably, the conductive material is nickel-plated or silver-plated. The conductive material can be adjusted according to actual conditions. The present invention is described by taking nickel-plated conductive material as an example.

[0013] Therefore, the terminal structure that can be used for heat riveting in the present invention has the following advantages: it is easy to process and manufacture, the terminal can be used for heat riveting, which effectively simplifies the installation process and improves the installation efficiency, while ensuring that the electrical performance and mechanical strength of the connection meet the application requirements.
