Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right",
The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Embodiment 1
As shown in figures 1 to 6, a kind of SMD riveting lid circulator using MIM technology, including shell 1 and circulator ontology 10, ring
Shape device ontology 10 is installed within the case 1, protects circulator ontology 10 by shell 1, and the lower part of shell 1 also sets up that there are three symmetrical
PIN needle mounting base 2, be mounted on PIN needle 7 in three PIN needle mounting bases 2, by PIN needle 7, signal, shell 1 can be transmitted
Top be additionally provided with cover board mouth 5, cover board 6 is riveted in cover board mouth 5, cover board 6 is installed by way of riveting, can be to avoid revolving
Metal fillings is generated during lid and worn metals, caused product are easy to appear quality risk.
The bottom end of shell 1 is also set up there are two location hole 4, in order to position.
It is also set up on circulator ontology 10 there are three fixed block 8 outstanding, three fixed blocks 8 are mounted on by bolt 9
The top of PIN needle 7, in order to which PIN needle 7 and circulator ontology 10 to be attached.
PIN needle mounting hole 3 is provided in PIN needle mounting base 2, PIN needle 7 is mounted in PIN needle mounting hole 3, can be fixed
PIN needle 7 avoids its movement.
Shell 1 is the shell of MIM sinter molding, using the MIM technique of powder metallurgy, using mold injection molding, by shell
Body 1 it is once sintered be finished product, make it have production capacity height, impulse- free robustness, without metal fillings the advantages of, be conducive to raising product quality.
Cover board 6 is stamping forming riveting lid, and cover board 6 directly on riveting to shell 1, can reduce BOM production cost,
The production efficiency of circulator is improved, to avoid the generation of metal fillings well.
It should be noted that a kind of mistake of the SMD riveting lid circulator using MIM technology disclosed by the utility model in production
Cheng Zhong, by comparing the production method of conventional housings, such as CNC processing, punching press, powder metallurgy and spelling riveting, the utility model choosing
It is analyzed, is chosen with a kind of MIM technique of powder metallurgy, and to " easily cutting iron " material and characteristic of tradition milling shell
