Description

Technical Field

[0001] The utility model belongs to the technical field of patch capacitors, and in particular relates to a horizontal patch capacitor structure. Background Art

[0002] Horizontal chip capacitors are an electronic component used for surface mount applications on circuit boards. Unlike traditional axial electrolytic capacitors or ceramic capacitors, the design of horizontal chip capacitors enables them to be horizontally attached to the surface of the circuit board instead of being inserted vertically into the circuit board holes. They have a more compact appearance and a more stable welding structure.

[0003] Existing publication number CN208478134U discloses a horizontal chip capacitor structure, including a shell lying horizontally on a circuit board and an inner core installed in the shell, characterized in that one side of the inner core has a plurality of bent pins bent at 90 degrees, the first bent portion of the bent pin is at least 1 mm long, the second bent portion of the bent pin has a patch portion fixed to the circuit board patch at the bottom end, and the patch portion is always parallel to the patch welding portion of the circuit board.

[0004] The existing horizontal chip capacitor structure still has the following shortcomings:

[0005] 1. In the existing design, the bent portion of the capacitor is designed to be flush with the bottom surface, which will lead to extremely poor heat dissipation efficiency between the bottom of the capacitor and the circuit board after welding, and easily cause damage to the capacitor in a hot environment.

[0006] 2. After welding, the two ends of the capacitor are wrapped with metal tin, which makes it smoother and more difficult for maintenance personnel to detect the capacitor.

[0007] 3. During use, capacitors may be damaged or short-circuited, so they need to be inspected and replaced. The size of existing chip capacitors is not marked on the surface, so when replacing them, they can only be judged based on color, size, shape, etc., which affects the maintenance efficiency.
