DETAILED DESCRIPTION

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] As shown in FIG. 1, the device includes a base 1, a cover 2, and a soft pressing pad 3. One side of the cover 2 (designated as the right side, and the other side as the left side) is movably connected to the right end of the base 1, and the left side of the cover 2 can be movably pressed to the left side of the base 1. The pressing pad 3 is installed at the middle bottom of the cover 2 and can be pressed to the base 1, and the needle electrode 4 is placed on the base 1 and is tightly fixed by the cover 2 and the pressing pad 3. Figure 1 As shown in FIG. 2, the base 1 has a protruding part 11, a welding groove 12, a through groove 13, a first shaft hole 14, and a notch 15. The protruding part 11 is located at the right end of the base 1, and the welding groove 12 is located at the left end of the base 1. The through groove 13 is located at the middle of the base 1, and the first shaft hole 14 is located at the left end of the base 1. The notch 15 is located at the left end of the base 1.

[0021] Figure 2 ​​​As shown, the base 1 has a raised portion 11 at one end (called the front end and the other end is the rear end), and a recessed welding groove 12 is formed on the raised portion 11. The rear end of the welding groove 12 is connected to the rear end of the base 1 through a through groove 13, and the bottom surface of the through groove 13 is flush with the top surface of the rear end of the base 1.

[0022] In use, a solder block (not shown in the figure) is placed in the soldering tank 12, and the tail end of the needle electrode 4 and the front end of the cable (not shown in the figure) are placed in the soldering tank 12 to perform soldering, so that the solder block melts and the needle electrode 4 is soldered together with the cable. At the same time, the front end of the needle electrode 4 extends to the rear end of the base 1 through the through groove 13.

[0023] In addition, a notch 15 is provided at the right end of the base 1, and a first shaft hole 14 is provided on both the front and rear sides of the notch 15.

[0024] like Figure 3 As shown, the pressure cap 2 is composed of a right branch 21, a middle branch 22 and a left branch 23 that are connected to each other. A second shaft hole 24 is provided on the right branch 21, which passes through its front and rear sides. The second shaft hole 24 is movably connected to each first shaft hole 14 on the base 1 through a movable shaft (not shown in the figure), so that the pressure cap 2 can rotate about the movable shaft as the axis.

[0025] The left branch 23 of the pressure cap 2 has a through-hole 25, in which a spring ball screw (not shown in the figure) is installed. When the left branch 23 of the pressure cap 2 is rotated to the left side of the base 1, the spring ball screw can lock the left side of the base 1, thereby fixing the pressure cap 2 and the base 1, making the pressure cap 2 more secure.

[0026] In addition, multiple through upper fixing holes 26 are provided on the middle branch 22 of the pressure cap 2.

[0027] like Figure 4 As shown, the pressure pad 3 has multiple through-holes 31, and each through-hole 31 is fixed to the upper fixing holes 26 of the pressure cover 2 by multiple connectors, thereby fixing the pressure pad 3 to the bottom of the pressure cover 2. The pressure pad 3 is also located behind the through groove 13. When the pressure cover 2 and the base 1 are fixed, the pressure pad 3 presses against the middle of the base 1 and onto the needle electrode 4, thus pressing and fixing the needle electrode 4 to prevent it from shaking. Simultaneously, the soft pressure pad 3 protects the tip of the needle electrode 4 from being damaged.

[0028] The needle electrode 4 welding device of this utility model has the following main technical effects:

[0029] 1. By designing the soldering groove 12, the solder block used for soldering the needle electrode 4 and the cable appears fuller;

[0030] 2. The pressure cap 2 stabilizes and presses down the needle electrode 4, preventing it from shaking and thus enabling the welding work to proceed smoothly;

[0031] 3. The ball spring screw makes the pressure cap 2 more secure, further improving the stability of pressing the needle electrode 4;

[0032] 4. By setting the pressure pad 3, the tip of the needle electrode 4 is protected from being crushed.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
