[0027] Embodiment
[0028] See Figures 1-4 as shown in
[0029] The present invention provides a capacitance soldering assisting tool, including: a solder assisting plate 20, a storage groove 30 and a solder flux applying component. The solder assisting plate 20 is used for placing the induction coil A to be soldered, and is placed in the storage groove 30, and through holes 221 through which the metal connection terminals of the induction coil A to be soldered pass are provided on the solder assisting plate 20; the storage groove 30 is filled with solder flux; the solder flux applying component is arranged on the solder assisting plate 20 and the storage groove 30, and adjusts the height of the solder flux applied to the end of the metal connection terminal of the induction coil A to be soldered.
[0030] The above setting replaces the process of manually applying solder flux to the end of the metal connection terminal of the induction coil A to be soldered, and enables the height of the solder flux applied to the end of the metal connection terminal of the induction coil A to be soldered to be controllable.
[0031] The solder flux applying component includes a pressing part and an applying part; the applying part is arranged in the storage groove 30 and is used for absorbing the solder flux; the bottom surface of the solder assisting plate 20 is in a fitting connection with the top of the applying part; the pressing part is placed on the upper surface of the solder assisting plate 20 and presses on the induction coil A to be soldered.
[0032] The pressing part is set as the pressure plate 10, and the pressure plate 10 has at least three different weights. According to the height of the solder flux applied to the end of the metal connection terminal of the induction coil A to be soldered, pressure plates 10 of different weights are selected, which is simple and convenient. A handle 11 is provided at the center of the pressure plate 10 to facilitate the operator to pick up and place.
[0033] The smearing part is set as the sponge 32; the sponge 32 is placed in the storage groove 30, and the sponge 32 absorbs the soldering flux in the storage groove 30. By setting the sponge 32, it can smear the soldering flux on the end of the metal terminal of the induction coil A to be soldered, and can also support the soldering plate 20 according to the elasticity of the sponge 32, so as to facilitate adjusting the depth of the metal terminal entering the sponge 32 by adjusting the weight of the pressing plate 10 pressing on the induction coil A to be soldered later. This makes the whole auxiliary tool flexible and convenient to use and has high stability.
[0034] A fixing groove 22 is provided on the soldering plate 20, and the induction coil A to be soldered forms a snap connection with the fixing groove 22; a through hole 221 is provided in the fixing groove 22.

[0036] An inner groove 31 is provided inside the storage groove 30; the top of the inner groove 31 supports the edge of the bottom of the soldering plate 20; the sponge 32 is placed in the inner groove 31, and the upper surface of the sponge 32 is flush with the top of the inner groove 31. Through such a setting, even if the weight of the pressing plate 10 and the soldering plate 20 is too heavy, it will not cause excessive extrusion of the sponge 32.
[0037] U-shaped handles 21 are provided on both sides of the soldering plate 20, which facilitates the operator to stably pick up and place the soldering plate 20 through the U-shaped handles 21, so that the induction coil A to be soldered on the soldering plate 20 will not be toppled during the process of transferring the soldering plate 20.
