High-power cylindrical capacitors are the basic components of high-power transmitters. Their performance indicators are directly related to the performance and accuracy of the equipment. Therefore, we must ensure that the performance indicators of high-power capacitors meet the equipment requirements.

This method has low production efficiency and cannot avoid human errors. Therefore, improving welding efficiency is an urgent problem that needs to be solved. Utility Model Content

[0028] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0029] like Figure 1-2 As shown, the utility model provides a ceramic capacitor device, including a capacitor body 1, a lead-out terminal 2 and a capacitor tooling 3. The lead-out terminal 2 is welded to an electrode of the capacitor body 1, and the lead-out terminal 2 is positioned at the welding point between the lead-out terminal and the capacitor body 1 by cooperating with the capacitor tooling 3.

[0030] Specifically, the capacitor body 1 is cylindrical, the inner wall 11 of the capacitor body 1 is an electrode, the welding point is located on the inner wall 11 , and the lead-out terminal 2 is the inner electrode lead-out terminal of the capacitor body 1 .

[0031] The capacitor tooling 3 includes a horizontal plate 31 and a vertical plate 32 connected perpendicularly to each other. The vertical plate 32 is located on the upper side of the horizontal plate 31 and forms an inverted T-shaped plane. That is, the vertical plate 32 is located on the upper surface edge of the horizontal plate 31 so that one side of the vertical plate 32 and one side of the horizontal plate 31 are located in the same plane. Moreover, a protrusion 321 is provided on the inverted T-shaped plane.

[0032] Preferably, the vertical plate 32 is located in the middle of the horizontal plate 31 .

[0033] like Figure 2 As shown, the lead-out terminal 2 includes an L-shaped portion 21 and an arc-shaped portion 22 connected to each other. The lower edge of the arc-shaped portion 22 is fixed to the free end of the horizontal arm 212 of the L-shaped portion 21, and the curved surface of the arc-shaped portion 22 is perpendicular to the horizontal arm 212. A first through-hole 213 is formed on the vertical arm 211 of the L-shaped portion 21. The first through-hole 213 is plugged into the protrusion 321, allowing the lead-out terminal 2 to be hung on the capacitor fixture 3. The arc-shaped portion 22 is placed against the inner electrode of the capacitor body 1, and the horizontal plate 31 is placed on the upper end of the capacitor body 1, thereby positioning the lead-out terminal 2 at the welding point of the capacitor body 1. The lead-out terminal 2 is welded to the inner wall 11 through the arc-shaped portion 22 and welded to the capacitor body 1.

[0034] To ensure that the upper edge of the arcuate portion 22 does not exceed the upper end surface of the capacitor body 1, the distance between the first through hole 213 and the lower end of the vertical arm 211 is greater than the height of the arcuate portion 22. Furthermore, to prevent the capacitor tooling 3 from falling from the middle of the capacitor body 1 into the interior of the capacitor body 1, the length of the side surface of the horizontal plate 31 that is coplanar with the vertical plate 32 is greater than the inner diameter of the capacitor body 1.

[0035] Preferably, the curvature of the arc portion 22 is consistent with the curvature of the inner wall 11, and a second through hole 221 is provided in the center of the arc portion 22, so that the solder between the arc portion 22 and the inner wall 11 can fit more closely, preventing the formation of a cavity in the middle where the solder cannot reach, thereby affecting the firmness between the two.

[0036] The lead-out terminal 2 is made of stainless steel. The capacitor fixture 3 is made of bakelite that is resistant to high temperatures of 130 degrees Celsius. The surface of the capacitor fixture 3 is coated with a paint layer to provide insulation and moisture resistance.
