Description
Technical field
The utility model is related to electronic component field more particularly to a kind of block isolating devices.
Background technology
The outer conductor capacitance that existing block isolating device uses is mounted on outer conductor one end, pin for band pin capacitance, pin one end
The other end is mounted on the outer conductor other end, and when installation, pin is difficult alignment, meanwhile, pin and ceramic condenser welding difficulty are big, appearance
Easily erosion weldering, causes pin and potsherd to fall off.Pin is difficult control with ceramic condenser concentricity and the depth of parallelism, even if with fixture,
Control also is difficult within 0.2mm, production efficiency is extremely low, is easy pressure break ceramic condenser, and scrappage is high.Because of pin and potsherd
Stress, the stability and poor reliability of product.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of blocking using no pin outer conductor ceramic condenser
Device.
A kind of block isolating device, it is characterised in that：It is described to lead outside including outer conductor, inner wire capacitance, outer conductor ceramic condenser piece
Body includes DC/RF input terminals and RF output ends, and DC/RF input terminals are fixedly connected with RF output ends, is arranged on the RF output ends
Fluted, the outer conductor ceramic condenser piece is placed in the groove, is connected on one side with RF output ends, another side and DC/RF
Input terminal is connected, and inner wire capacitance one end is connected with DC/RF input terminals, and the other end is connected with RF output ends.
In said program, the surface of the outer conductor potsherd capacitance sheet uses electroplated aluminum silver electroplating processes.
In said program, the outer conductor ceramic condenser piece is round, rectangular or arbitrary shape.
In said program, the shape of the groove is identical as the shape of outer conductor ceramic condenser piece.
In said program, the DC/RF input terminals are fixedly connected with the RF output ends using insulated screw.
The beneficial effects of the utility model are compared with prior art：The outer conductor ceramic condenser of use is without using any
The metal pins of form or shape are directly installed in the groove of outer conductor setting, are quickly and expediently installed, and outer conductor is made pottery
For porcelain capacitance without pressure break risk, reliability is high.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model block isolating device；
Attached body description of symbols：1, DC/RF input terminals, 2, RF output ends, 3, inner wire capacitance, 4, outer conductor capacitance, 5, absolutely
Edge screw.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1：A kind of block isolating device, including outer conductor, inner wire capacitance 3, outer conductor ceramic condenser piece 4, outer conductor
Including DC/RF input terminals 1 and RF output ends 2, outer conductor DC/RF input terminals 1 are solid using two insulated screws 5 with RF output ends 2
Fixed connection.Be arranged fluted on RF output ends 2, outer conductor ceramic condenser piece 4 is placed in groove, on one side with 2 phase of RF output ends
Even, another side is connected with DC/RF input terminals 1.3 one end of inner wire capacitance is connected with the center lock pin of DC/RF input terminals 1, separately
One end is connected with the center lock pin of RF output ends 2.
In one embodiment, outer conductor ceramic condenser piece 4 be round, rectangular or arbitrary shape, the shape of groove with lead outside
The shape of body ceramic condenser piece 4 is identical, can ensure outer conductor ceramic condenser piece 4 and outer conductor DC/RF input terminals 1 and RF in this way
Output end 2 is in close contact, and the surface of outer conductor ceramic condenser piece 2 carries out metalized, using the electroplating processes of electroplated aluminum copper,
It can ensure to contact with outer conductor DC/RF input terminals 1 and RF output ends 2 and well there is stronger anti-pressure ability simultaneously.
One end of inner wire capacitance 3 is inserted into the lock pin at 1 center of DC/RF input terminals by assembling steps, the first step；Second
Outer conductor ceramic condenser piece 4 is packed into the groove that RF output ends 2 open up by step；Third walks, and RF output ends 2 and DC/RF is defeated
Enter 1 position alignment of end, the other end of inner wire capacitance 3 is inserted into the lock pin at 2 center of RF output ends, and edge spiral shell is thoroughly done away with finally by two
DC/RF input terminals 1 and RF output ends 2 are fixedly mounted nail 5.
Above example is only to illustrate the technological thought of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is every according to the utility model proposes technological thought, any change is made on the basis of technical solution, each falls within this reality
With in novel protected range.
