Description
Technical field
The utility model relates to a kind of syndeton of filter parts, especially a kind of upper cover of filter and connection structure of outer shell.
Background technology
The filter circuit that power-supply filter is made up of electric capacity, inductance and resistance.Filter can carry out effective filtering to the frequency beyond the frequency of characteristic frequency in power line or this frequency, obtains the power supply signal of a characteristic frequency, or eliminates the power supply signal after a characteristic frequency.The upper cover of traditional filter and connection structure of outer shell are a upper cover lid and put on shell.There is gap between such lid postpone upper cover and shell, due to the postpone of upper cover lid, also need to build fluid sealant, therefore when building, fluid sealant can be made to ooze out, affect product quality.
Summary of the invention
The purpose of this utility model be to provide a kind of upper cover and shell connection reliability good, fitness is high, the upper cover of the filter improved the quality of products and connection structure of outer shell.
In order to achieve the above object, the technical solution of the utility model is: a kind of upper cover of filter and connection structure of outer shell, comprise shell and upper cover, upper cover lid is put on shell, two pieces of dividing plates are provided with in described shell, enclosure is divided into three regions by dividing plate, two madial walls in the region of both sides all has mounting blocks, described mounting blocks is provided with installation groove, described upper cover comprises two, and on to cover the installation be provided with installing groove fit protruding, described two upper cover lids are put in the two side areas in portion in the enclosure.
After adopting said structure, the utility model adopts on two madial walls in the region of both sides all has mounting blocks, and described mounting blocks is provided with installation groove, above covers the installation be provided with installing groove fit protruding.Therefore when mounted, as long as two upper covers are arranged on the region of both sides respectively, and the installation of upper cover projection is installed in the installation groove of mounting blocks, installation reliability is good, fitness is high, and in casting process, upper cover and shell can not loosen, fluid sealant can not flow out, and improves the quality of product.
