Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 2,3,4, it is the schematic diagram of the utility model cylindrical capacitor fixed structure embodiment.Cylindrical capacitor fixed structure in the present embodiment comprises four jaws 21, the bottom of these four jaws 21 is fixed on the installation frame 20 and these four jaws 21 are evenly distributed on the same circumference, and the inboard of each jaw 21 is projection 211(this projection 211 and jaw concentric that the top of the inboard of circular arc and each jaw 21 has circular arc).
By being evenly distributed on four jaws, the 21 clamp capacitance devices 30 of same circumference, can carry out to capacitor 30 position limitation protection of four direction; Because the top of each jaw 21 has projection 211, capacitor 30 firmly can be bound simultaneously, be avoided the axial vibration of capacitor 30.That is to say that above-mentioned fixed structure can prevent loosening in either direction of capacitor 30, thereby the solder joint that guarantees capacitor 30 is stable.
In actual applications, the quantity of jaw 21 also can increase as required, for example is five or more.Above-mentioned fixed structure may be used on multiple different applied environment, for example in the plastic casing frequency converter (at this moment, installation frame 20 is the plastic casing of frequency converter).
