Electronic component seat of annular structure

Abstract

The invention discloses an electronic component seat of an annular structure. The electronic component seat can be installed on a circuit board through electrical connection and comprises a seat body, and a plurality of external connection pins and a plurality of internal connection pins which are installed on the seat body. The seat body comprises at least one inner surrounding wall for installing the internal connection pins thereon, one outer surrounding wall which is used for installing the external connection pins thereon and surrounds the periphery of the inner surrounding wall, one annular basal wall connected between the outer surrounding wall and the inner surrounding wall, and one annular space commonly defined by the outer surrounding wall, the inner surrounding wall and the annular basal wall. According to the invention, through additional arrangement of the inner surrounding wall for installing the internal connection pins thereon on the seat body, under the condition that the volume is not changed, the quantity of the connection pins of the electronic component seat can be increased.

Description

technical field [0001] The invention relates to an electronic component seat, in particular to a ring-shaped electronic component seat suitable for being mounted on a circuit board in a surface bonding manner. Background technique [0002] An electronic component holder is an electronic product that can accommodate electronic parts such as coils, etc. The electronic product is electrically connected to a circuit board. With the different ways of assembling on the circuit board, the existing electronic component holder It can be divided into two types: plug-in type and surface-mounted type. Among them, the plug-in electronic component seat can also be called a dual in-line package (dualin-linepackage, referred to as DIP), which uses the pins that go down through the circuit board, and the through-hole technology (through-hole technology) Mates bonded to the circuit board. The surface-mounted electronic component holders can also be called surface-mount devices (SMD for shor...

AI Technical Summary

Problems solved by technology

[0006] When the existing electronic component holder 2 is assembled, although it is not necessary to provide jacks on the circuit board 21, and the overall volume can be reduced, each pin 23 must have the protruding foot section 231 extending horizontally, which is subject to The structure of the seat body 22 is limited, the pins 23 can only be arranged on the surrounding wall 222, and the protruding foot section 231 is horizontally protruded from the outer periphery of the seat body 22, because the volume is constant , the total length of the surrounding wall 222 is fixed, so although the volume of the electronic component seat 2 known as SMD can be reduced, the number of the pins 23 that can be installed is relatively small
