[0050] The terminal assembly 10 is provided with a positioning groove 16 on the terminal 12 or the terminal post 14. The positioning portion 18 is clamped in the positioning groove 16 to pre-fix the terminal 12 and the terminal post 14, thereby assisting assembly positioning, reducing assembly difficulty, and improving assembly efficiency.

[0051] Specifically, the terminal assembly 10 is assembled on the power board or control board of the product, and the terminal 12 is fixed on the terminal post 14.

The wall thickness D of the positioning portion 18 is related to the size, processing material and processing requirements of the terminal 14 or the terminal 12. The thickness H of the positioning groove 16 is designed according to the wall thickness D of the positioning portion 18, such as Figure 1 and Figure 8 As shown, the thickness H of the positioning groove 16 is greater than the wall thickness D of the positioning portion 18, so that the connecting terminal 12 can be easily buckled into the positioning groove 16 without loosening and jumping out, thereby achieving the purpose of fixing and positioning.

[0056] In one embodiment, the thickness H of the positioning groove 16 is greater than the wall thickness D of the positioning portion 18, and the difference between the thickness H of the positioning groove 16 and the wall thickness D of the positioning portion 18 is in the range of [0.3mm, 0.7mm].

When the terminal block 12 and the terminal post 14 are assembled, the terminal block 12 is buckled in parallel from the opening direction formed by the coupling portion 20, so that the positioning portion 18 of the terminal post 14 is clamped in the positioning groove 16, and the terminal block 12 and the terminal post 14 can be fixed. In this way, there is no need to change the original structure of the terminal post 14, and the terminal block 12 and the terminal post 14 can be fixed by only providing the coupling portion 20 on the terminal block 12.

[0062] The positioning portion 18 includes at least a portion of the second body portion 26, or the terminal 14 includes the positioning portion 18, and the second body portion 26 is connected to the positioning portion 18, that is, the positioning portion 18 can be a portion of the second body portion 26 inserted into the positioning groove 16, or the entire second body portion 26 can be inserted into the positioning groove 16 as the positioning portion 18.

[0063] In some embodiments, the terminal post 14 includes two supporting portions 22 , and a width W of the connecting portion 20 between the two supporting portions 22 and the second body portion 26 is smaller than a distance L between the two supporting portions 22 .

[0064] In this way, there is a gap between the combining portion 20 and the supporting portion 22 , so that the positioning portion 18 can be smoothly inserted into the positioning groove 16 .

[0065] Specifically, the terminal block 12 includes a first main body portion 24 and a coupling portion 20, and the first main body portion 24 and the coupling portion 20 surround a positioning groove 16. The coupling portion 20 is buckled between two supporting portions 22 of the terminal post 14, so that the positioning portion 18 of the terminal post 14 is stuck in the positioning groove 16. Figure 5 As shown, the width W of the coupling portion 20 is smaller than the distance L between the two supporting portions 22, so that there is a gap between the coupling portion 20 and the supporting portion 22. When the coupling portion 20 is buckled into between the two supporting portions 22 of the terminal 14, no interference will occur between the coupling portion 20 and the supporting portion 22, so that the positioning portion 18 can be smoothly buckled into the positioning groove 16.

[0066] In one embodiment, the width W of the coupling portion 20 is less than the distance L between the two supporting portions 22, and the difference between the width W of the coupling portion 20 and the distance L between the two supporting portions 22 is in the range of [0.3 mm, 0.7 mm]. The difference between the width W of the coupling portion 20 and the distance L between the two supporting portions 22 can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm or 0.7 mm, or any other value in the range of [0.3 mm, 0.7 mm]. In this way, on the one hand, the positioning portion 18 of the terminal block 12 can be easily buckled into the positioning groove 16, and on the other hand, it can prevent the positioning portion 18 from easily falling out of the positioning groove 16 due to the excessive gap between the positioning portion 18 and the positioning groove 16.

[0067] Preferably, the difference between the width W of the coupling portion 20 and the distance L between the two supporting portions 22 is 0.5 mm (including error), so that the two components can be assembled without interference when buckled in, and the positioning portion 18 can be easily buckled into the positioning groove 16 without loosening and jumping out.

[0072] The mounting portion 30 is cylindrical, and its size is set according to the aperture of the mounting hole 28. The recess 34 can be formed by opening a semicircular hole on the coupling portion 20, wherein the aperture of the semicircular hole is set according to the aperture of the mounting hole 28, thereby enabling the recess 34 to be clamped on the mounting portion 30 of the mounting hole 28, thereby playing the role of fixing the terminal 12 and the terminal post 14.
