Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the plug-in power inductor with stable plug-in pins in this embodiment includes a housing 1, a magnetic core 2, a winding group 3, two plug-in pins 4 and two telescopic sleeves 5, where the magnetic core 2 is installed in the housing 1, the winding group 3 is sleeved on the magnetic core 2, the two telescopic sleeves 5 are installed at the bottom of the housing 1, the plug-in pins 4 penetrate through the housing 1, one end of the plug-in pins is electrically connected with the winding group 3, and the other end of the plug-in power inductor extends out of the bottom of the housing 1 and into the telescopic sleeves 5. The two telescopic sleeves 5 are symmetrically distributed along the center of the shell 1. The firm type plug-in components power inductance of participating in of this embodiment installs telescope tube 5 in the bottom of shell 1, and the bottom of participating in 4 stretches into telescope tube 5 in, accomplishes the installation back at plug-in components power inductance, and telescope tube 5 stretches out to the circuit board downwards on, has effectively increased the intensity of participating in 4, guarantees its fastness, and simultaneously, can keep apart the contact of participating in 4 and other circuit elements, guarantees circuit safe operation.
As shown in fig. 2, in the present embodiment, the telescopic sleeve 5 includes a first sleeve 51, a second sleeve 52 and a resistance rubber ring 53, the first sleeve 51 is fixed at the bottom of the housing 1, the second sleeve 52 is slidably sleeved in the first sleeve 53, the resistance rubber ring 53 is disposed between the first sleeve 51 and the second sleeve 52, the bottom ends of the pins 4 extend into the first sleeve 51 and the second sleeve 52, and the resistance rubber ring 53 increases the frictional resistance between the first sleeve 51 and the second sleeve 52, so as to effectively prevent the second sleeve 52 from easily sliding out of the first sleeve 51; during installation, the second sleeve 52 slides upwards to be retracted into the first sleeve 51, so that the pin 4 can be conveniently installed, after installation, the second sleeve 52 slides downwards to the surface of the circuit board, the pin 4 is combined with the pin to ensure the strength and firmness of the pin 4, the power inductance of the whole plug-in unit is supported, meanwhile, the pin 4 can be isolated from other circuit elements, and the circuit safety is ensured. The bottom of the second sleeve 52 extends outwardly to form a retaining ring 54 to facilitate the support of the second sleeve 52 on the circuit board surface.
The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the above disclosed embodiments, and shall cover various modifications, equivalent combinations, according to the essence of the present invention.
