Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The first embodiment,
Fig. 1 and 2 show a capacitor mounting structure, which comprises a fixing frame 1, wherein the fixing frame is made of an insulator and is non-conductive to ensure the use safety of a mounting frame. The fixing frame is fixed on the circuit board 2, and the capacitor connecting contact on the circuit board is surrounded in the fixing frame, so that the cathode and the anode of the chip capacitor can be contacted with the connecting contact on the circuit board when the chip capacitor is clamped in the fixing frame, and a loop is formed.
The fixing frame 1 is rectangular, and the shape of the fixing frame is matched with that of the capacitor 3; the capacitor is clamped in the fixing frame, and the height of the fixing frame is less than or equal to that of the capacitor; the shape and size of the fixing frame are matched with the capacitor, so that the capacitor can be fixed without occupying too much area on the circuit board.
The outer wall of the fixing frame is symmetrically provided with reinforcing ribs 5, and the reinforcing ribs correspond to the positions of the clamping and fixing devices, so that the clamping and fixing devices are prevented from generating acting force damage on the fixing frame when being used for a long time, and a strong supporting force is provided for the clamping and fixing devices;
the upper end surface of the fixing frame is symmetrically provided with grooves 8 which are arc-shaped and are positioned at the inner side edge of the fixing frame. The groove provides a gap for the fixing frame, and when the capacitor is replaced or pulled out, the capacitor can be clamped at the groove conveniently and pulled out easily due to the large surface area of the capacitor exposed at the groove, so that the force of hands or tools can be exerted conveniently.
A plurality of bolt holes 6 are formed in the fixing frame, and bolts are arranged in the bolt holes and fix the fixing frame and the circuit board together; the bolt is fixed to facilitate the mounting or dismounting of the fixing frame on the circuit board. A reinforcing strip 7 is arranged at the corner of the fixed frame along the height of the fixed frame; the corner of fixed frame can be consolidated to the reinforcement strip, makes fixed frame more durable, and is difficult for the fracture.
The inner wall of the fixing frame 1 is symmetrically provided with clamping devices 4 for fixing the capacitor, and the clamping devices are used for clamping two ends of the capacitor, so that the clamping devices are insulators to ensure the use safety of the capacitor and the mounting frame. The fastening device 4 includes an elastic member; in the present embodiment, the chucking device 4 includes the elastic member spring 41, and further includes an insulating pressing plate 43; one end of the spring is fixed on the inner wall of the fixed frame, and the other end of the spring is fixedly connected with an insulating pressing plate. The insulating pressing plate is made of an epoxy glass cloth pressing plate FR 4.
The principle of the clamping device is similar to that of a battery seat, and the capacitor is fixed in the fixing frame through the pressure of springs at two ends. However, since the spring is made of metal, the insulating paint is not completely coated and is easily conductive to the motor of the capacitor, and therefore, the insulating plate is further arranged, so that the electrode of the capacitor can be completely blocked.
In addition, if the spring is directly contacted with the capacitor, because the contact area of the spring and the capacitor is small, when the elastic force is large, the pressure of the spring on the capacitor is large, and the capacitor is easy to damage, the pressure on the capacitor can be reduced under the action of the insulating plate, and the use safety of the capacitor is ensured.
Example II,
The difference between this embodiment and the first embodiment is that the elastic member is different, and as shown in fig. 3, in this embodiment, the elastic member in the fastening device is a spring 42. The surface of the elastic sheet 42 is coated with an epoxy resin insulating paint to ensure insulation. When the capacitor directly contacts the elastic sheet, the contact area between the elastic sheet and the capacitor is large, so that the structure of the capacitor cannot be damaged by large pressure.
Compared with the prior art, the utility model difference lies in:
a. the utility model is specially used for the surface mounted capacitor, and is mainly applied to the surface mounted capacitor, so as to facilitate the installation and the disassembly of the capacitor, the capacitor is pressed into the fixing frame to complete the installation, and the capacitor is directly pulled out during the disassembly;
b. the fixing frame can be easily installed and detached, is suitable for most common capacitors in the market, does not need to improve the structure of the capacitor, and can be directly used;
c. simple structure and small occupied circuit board area.
The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
