Description

Technical Field

[0001] This utility model relates to the field of thin film capacitor technology, and in particular to an ultra-thin thin film capacitor with countersunk hole mounting. Background Technology

[0002] Because TVs are becoming increasingly thinner, the thickness requirements for various components are also decreasing, and the internal space is becoming very compact. For products with a pin pitch ≥15mm, our current thickness limit for film capacitors is around 5mm. Further reducing the thickness is extremely difficult to produce due to equipment limitations; even custom-made equipment is difficult to operate, and the volume cannot be changed. Typical product shapes are as follows... Figure 5 Installation method as follows Figure 4 It can only be installed directly onto the PCB board, taking up at least more space than the product volume, which is not conducive to miniaturization and the need for ultra-thin designs. Utility Model Content

[0003] To address the problem that existing film capacitors can only be mounted on a PCB board, occupying at least more space than the product volume, which is not conducive to miniaturization and the demand for ultra-thin designs, this invention provides an ultra-thin film capacitor with countersunk hole mounting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An ultra-thin film capacitor with countersunk hole mounting includes a PCB board and a capacitor body. Both sides of the capacitor body are provided with stepped portions for embedding mounting holes provided on the PCB board, so as to reduce the height of the upper surface of the capacitor body from the PCB board. The capacitor body is provided with a plurality of pins, and the PCB board is provided with corresponding pin holes.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: By designing a step at both ends of the capacitor body and setting mounting holes on the corresponding PCB board, the capacitor body can be countersunk, which can improve space utilization and reduce height space. This can effectively solve the needs of ultra-thin and miniaturized TV boards, while ensuring that its reliability is not affected. It can greatly meet market demand and provide visual inspection.

[0008] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0010] like Figures 1 to 3 As shown, this utility model embodiment includes a PCB board 1 and a capacitor body 2. Both sides of the capacitor body are provided with stepped portions 201 for embedding the mounting holes 102 provided on the PCB board 1, so as to reduce the height of the upper surface of the capacitor body 2 from the PCB board 1. The capacitor body 2 is provided with a plurality of pins 3, and the PCB board 1 is provided with corresponding pin holes 101.

[0011] like Figure 4 and 5 As shown, in existing systems, the capacitor body 2 is mounted against the surface of the PCB board 1, resulting in a relatively high distance between its upper surface and the PCB board 1. In this embodiment, the capacitor body 2 and the PCB board 1 are mounted as follows: Figure 1 As shown, the stepped portions 201 on both sides of the capacitor body 2 are inserted into the mounting holes 102 provided on the PCB board 1, so that the capacitor body 2 is installed in a recessed manner. This allows part of the capacitor body 2 to be hidden under the PCB board 1, greatly reducing the space utilization rate above the PCB board 1, thereby realizing the miniaturization and ultra-thinness of the customer product.

[0012] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
