Improved network filter housing

Abstract

The invention relates to the technical field of a network filter and especially relates to an improved network filter housing. The improved network filter housing comprises a base. The base is a rectangular box body, of which the top surface is opened. The side walls of the base are provided with a plurality of L-shaped pins. The pins comprise vertical sections and horizontal sections, wherein the upper ends of the vertical sections extend out of the top surface of the base, and the horizontal sections are arranged under the bottom surface of the base; and one end of each horizontal section is connected with the lower end of the corresponding vertical section, and the other end extends to the outer side of the base and is vertical to the side wall of the base. According to the improved network filter housing, through improving the shapes of the pins and the positions of the pins, the length of the pin extending out of the base is reduced, so that the pins are not easy to slant and deform; the portions, exposed in the air, of the pins are smaller, so that oxidation is prevented; and the face, wherein the pin is contacted with the circuit board is more smooth, so that tin consumption amount can be reduced during welding, and the product quality and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of network filters, in particular to an improved network filter shell. Background technique [0002] At present, network filters have been widely used in communication networks, and general network circuit devices are equipped with network filters. The existing network filter includes a housing, a number of pins and filter components, the shape of the pins is roughly the same as that of the integrated circuit chip, and it is packaged by flat packaging technology (QFP), such as in the patent No. 200820202972.9 In the Chinese utility model patent, a "encapsulation mode network filter" is disclosed. Its pins protrude from the side of the network filter housing, and the protruding part is in the shape of "Z". This method makes the length of the pins longer Long, prone to skew deformation, and it is difficult to ensure that multiple pins are on the same plane as the soldered side of the circuit board, resulting...
