Embodiment
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
As shown in Figures 1 and 2, the invention discloses a kind of porcelain Jie punching to filter integrated package, including substrate 1, some ceramics
Tubular capacitor 2 and contact pin 3 corresponding with the quantity of ceramic tubular electric capacity 2；Some ceramic tubular electric capacity 2 are arranged on substrate 1, each
A contact pin 3 is respectively provided with ceramic tubular electric capacity 2, contact pin 3 is welded to connect through ceramic tubular electric capacity 2 with ceramic tubular electric capacity 2,
Interior termination electrode as ceramic tubular electric capacity 2.Wherein ceramic tubular electric capacity 2 includes cylindrical shape porcelain tube 5 and inner electrode layer 6；It is interior
Electrode layer 6 is by silk screen printing in the inside of cylindrical shape porcelain tube 5.The inner electrode layer 6 of some ceramic tubular electric capacity 2 count it is identical or
It is different.Porcelain Jie punching filtering integrated package in the present invention, integrated package is made using ceramic tubular electric capacity 2, and its parameter distribution is uniform,
Compact-sized, anti-Conduction Interference ability is strong.Meanwhile set inside the ceramic tubular electric capacity 2 used in porcelain Jie punching filtering integrated package
Inner electrode layer 6 is put, by the quantity for changing inner electrode layer 6 so that the capacity of each ceramic tubular electric capacity 2 is different, Ke Yishi
Existing multifrequency or mixing and filtering.
The invention also discloses a kind of filtering electrical connector, as shown in Figures 3 and 4, including above-mentioned porcelain is situated between and worn its structure
The heart filters integrated package and housing；Porcelain Jie punching filtering integrated package is assemblied in housing, the substrate 1 in porcelain Jie punching filtering integrated package
It is connected with case weld.Housing is metal shell, the external electrode as ceramic tubular electric capacity 2.Filtered electrical disclosed by the invention
Connector, reliable product quality, and because it can realize mixing or multifrequency filtering, it is applied widely.
The invention also discloses the preparation method of filtering electrical connector, its flow as shown in figure 5, including：
Step 1, welding equipment filtering unit simultaneously carry out Electrical Indexes detection to filtering unit；Wherein filtering unit include contact pin and
Ceramic tubular electric capacity；Contact pin passes through ceramic tubular electric capacity, is welded to connect with ceramic tubular electric capacity；Electrical Indexes detection includes electric capacity
Measure detection, proof voltage detection, Insulation monitoring, insertion loss detection and temperature characterisitic detection.To ensure the quality of filtering unit,
Carry out also including screening operation before Electrical Indexes detection, filter out qualified filtering unit and carry out Electrical Indexes detection.Screening
Operation includes：Mechanical oscillation, boiling water digestion, temperature shock, aging.
Step 2, step 1 detected into qualified filtering unit and substrate welding equipment, porcelain Jie punching filtering integrated package is made, and it is right
Porcelain Jie punching filtering integrated package carries out embedding；
Step 3, mechanical oscillation detection, plug detection, airtight detection are carried out to porcelain Jie punching filtering integrated package after embedding
And Electrical Indexes detection；Wherein Electrical Indexes detection includes capacitance detection, proof voltage detection, Insulation monitoring, insertion loss inspection

Middle Electrical Indexes detection includes capacitance detection, proof voltage detection, Insulation monitoring, insertion loss detection and temperature characterisitic detection.
Because the filtering integrated package of the present invention is made in completely open state, just by it after completing
Load in the housing of filtering electrical connector, its manufacture difficulty, which has inherently obtained pole, significantly to be reduced, and traditional mode of production mode
Filtering electrical connector be with the related cross-operation of housing, in housing implement production operation it is more difficult.
How much the electric connector core number and mixing number of channels of the present invention can according to circumstances be set, meanwhile, split system
It is standby, can be extremely simple easy to the real-time monitor and detection of each section, maintenance, replacing.Because traditional mode of production mode is some components
With the related cross-operation of housing, thus electrical property, soldering reliability, the quality index such as airtight reliability are filtered, in actual production
During can not be monitored and detect, often solidification assembling complete after could carry out, so core number and be mixed
Number of channels more multi-product qualified probability is lower；And the above situation is not present in the present invention, the qualification rate of product is very high.
Each link of filtering electrical connector preparation process, is all limited by quality inspection and technical supervision, if because can not
When prediction factor influences and causes the product quality to go wrong, due to each link product still in two-sided visual with it is open
State, it can rapidly, accurately find out the odjective cause for causing quality problems, the matter that the enough simple and reliable solutions of and can are occurred
Amount problem.Simultaneously, additionally it is possible to work up and fundamentally evade the measure for repeating identical quality problems and scheme.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
