Abstract

The utility model relates to a surface mounted type separator, comprising a housing, an inner conductor inside the housing and a cover plate. The utility model is characterized in that: the bottom part of the housing is jointed with a PCB board with three protruded ports; a projecting base seat at the central bottom of the housing is closely connected with the periphery of the inner wall of a central hole in the PCB board; the bottom face of the base seat is parallel with the lower plane of the PCB board. The side wall of the housing is left with three split notches; the extension end of the inner conductor is induced downlink along the notches and then is electrically connected with the PCB board. A cover is connected with the whorl at the upper port of the housing. The bottom of the housing is additionally provided with a PCB board, so that an apparatus can be connected to the ground to a utmost extent, and the apparatus can be precisely positioned through the three ports of the PCB board; the notches excavated at the side wall of the housing lead the load to stand the high temperature wave-soldering, having great radiating effect. The utility model can be applied directly on the PCB board, the manually welded installation is not needed; and the utility model is suitable to be manufactured in mass; the installation efficiency and the apparatus reliability are enhanced.

Description

Surface patch formula isolator

Technical field

The utility model belongs to technical field of electronic components, is specifically related to the isolator that a kind of miniaturization can use wave-soldering form surface patch formula to install.

Background technology

Existing isolator mounting means is with stay bolt isolator to be fixed on the printed substrate earlier, the lead-out wire of components and parts is passed hole on the printed substrate, again with artificial welding.This manual mode of operation can not adapt to industrial automation production requirement in enormous quantities, not only speed is slow, and,, the reliability of finished product device in application will be influenced as cause errors such as rosin joint, sealing-off because of lack of skill owing to have many uncertain factors in the manual operation.

The utility model content

The purpose of this utility model provides the new construction that a kind of simple in structure, easy for installation, service-strong is fit to the isolator of paster production technology.

For achieving the above object, the technical scheme that adopts is: surface patch formula isolator, comprise cavity (being outer conductor), place inner wire and cover plate in the described cavity, it is characterized in that: the bottom of described cavity fits with the printed substrate (abbreviation pcb board) that has three outstanding ports, place the projection base at described cavity bottom center, with the inner peripheral wall close proximity of described pcb board centre bore, the bottom surface of described base is concordant with the lower plane of described pcb board.

The sidewall of described cavity is equipped with three discrete notches, and the exit of inner wire is drawn along notch is descending, is electrically connected with described pcb board.

Described lid is threaded with the upper port of described cavity.

The beneficial effects of the utility model are: the bottom of cavity installs pcb board additional, makes device at utmost carry out ground connection, and can accurately locate by three ports of appended pcb board; The fluting design that cavity wall is special, the protection load can stand the installation process of high temperature wave-soldering,, at utmost dispel the heat simultaneously.The utility model can directly be used on pcb board, and manually welded and installed is fit to produce in enormous quantities, has improved the reliability of installation effectiveness and device, has reduced user's assembly cost.
