[0022] Example

[0023] like Figure 1-5 As shown, this embodiment provides a reactor terminal, including an injection-molded terminal 1, wherein the main body of the injection-molded terminal 1 is an arc-shaped plate 2, two terminal blocks 3 are provided at the front end of the arc-shaped plate 2, a fixing groove 4 is horizontally provided in the terminal block 3, a lead groove 5 is vertically opened from the top to the middle of the terminal block 3, a terminal plug 6 is inserted in the fixing groove 4, and the terminal plug 6 is interference-fitted with the fixing groove 4. By setting the terminal plug 6 to be interference-fitted with the fixing groove 4, the terminal plug 6 and the reactor can be stably fixed.

[0024] Preferably, the terminal plug 6 is a U-shaped structure, a terminal post 7 is provided at the top left of the terminal plug 6, a force-applying plane 8 is provided at the top right of the terminal plug 6, an anti-dropping structure is provided at the outer edge of the terminal plug 6, an inverted U-shaped skin-cutting fixing groove 9 is provided downwardly in the middle of the terminal plug 6, and a terminal guide groove 10 is provided at the bottom of the terminal plug 6. By providing the force-applying plane 8, it is convenient to apply external force to the terminal plug 6, and the enameled wire 12 is better fixed. By providing the anti-dropping structure, the terminal plug 6 can be better tightly combined with the terminal block 3 to prevent the terminal plug 6 from falling off.

[0025] Preferably, an auxiliary cutting boss 11 is provided inside the fixing groove 4, and the height of the auxiliary cutting boss 11 is the same as the height of the bottom of the lead groove 5, and the auxiliary cutting boss 11 is adapted to the terminal guide groove 10. By providing the auxiliary cutting boss 11, on the one hand, the auxiliary cutting boss 11 can support the enameled wire 12 and facilitate the inverted U-shaped skin cutting fixing groove 9 to cut the outer skin of the enameled wire 12, and on the other hand, the auxiliary cutting boss 11 cooperates with the terminal guide groove 10 to better fix the terminal plug 6.

[0026] Preferably, an enameled wire 12 is placed in the lead-in groove 5. By providing the lead-in groove 5, the enameled wire 12 can be better fixed.

[0027] Preferably, the inverted U-shaped skin cutting fixing groove 9 is a groove body whose width gradually narrows from bottom to top, and the width of the bottom of the inverted U-shaped skin cutting fixing groove 9 is greater than the wire diameter width of the enameled wire 12, and the width of the top of the inverted U-shaped skin cutting fixing groove 9 is less than the wire diameter width of the enameled wire 12. By setting the inverted U-shaped skin cutting fixing groove 9 to gradually narrow from top to bottom, it is convenient to destroy the insulating paint on the surface of the enameled wire 12 during the continuous relative displacement between the enameled wire 12 and the terminal plug 6, so as to realize the passage between the enameled wire 12 and the terminal plug 6.

[0028] Preferably, the terminal post 7 is provided with a circular terminal hole 13 .

[0029] Preferably, the anti-drop structure includes inverted triangle blocks 14 symmetrically arranged on both sides of the terminal plug 6, and the distance between the two inverted triangle blocks 14 is greater than the width of the fixing groove 4. By providing the inverted triangle blocks 14, on the one hand, it is convenient for the terminal plug 6 to be inserted into the fixing groove 4 and not easy to fall off, and on the other hand, the distance between the two inverted triangle blocks 14 is greater than the width of the fixing groove 4, which can better achieve the interference fit between the terminal plug 6 and the fixing groove 4.

[0030] Working principle: First, pass the unpeeled enameled wire 12 through the lead groove 5 of the injection-molded terminal 1, and then insert the terminal plug 6 along the matching groove of the injection-molded terminal 1. At this time, a downward force is applied to the force-applying plane 8 of the terminal plug 6 through the tooling, so that the inverted U-shaped skin-cutting fixing groove 9 of the terminal plug 6 contacts the unpeeled enameled wire 12. At this time, the unpeeled enameled wire 12 is restricted by the displacement of the auxiliary cutting boss 11 inside the injection-molded terminal 1, so that the unpeeled enameled wire 12 and the terminal plug 6 continue to displace relative to each other. Since the fixing groove 4 is set as an inverted U-shaped structure, as the above-mentioned displacement proceeds, the inverted U-shaped skin-cutting fixing groove 9 of the terminal plug 6 scratches the insulating paint layer on the surface of the enameled wire 12, and at this time, the terminal plug 6 and the enameled wire 12 achieve normal passage. After completing the above process, the terminal plug 6, the injection-molded terminal 1 and the enameled wire 12 are assembled. Through the interference fit between the outer edge anti-slip structure on both sides of the terminal plug 6 and the matching groove of the injection-molded terminal 1 and the inverted triangle structure, the terminal plug 6 and the injection-molded terminal 1 can be fixed and prevented from slipping off.
