Description
Technical field
The utility model relates to field of connectors, and in particular to the angle connector that a kind of electrical property improves.
Background technology
Connector is that very extensive conventional device is applied in the electronic component products of thousands of kinds, and application is non-
Often a kind of extensive general-purpose device, product can be widely applied to the military projects such as radar system, space flight and communication or civil area, also should
For instrument, automatically control, the industrial circle such as communicate.Radio frequency connector is widely used in signal transmission network, plays transmission
Line electrical connection, centrifugation.
To ensure that connector electrical property meets user's request, the characteristic impedance of connector span line should be in the range of 50 ± 2 Ω.
So needs are a kind of to optimize the method for connector electrical property by adjusting span line impedance.
Connector can be divided into straight connector and angle connector by profile point.Angle connector can be divided into micro-strip connection
Device, adapter, connect cable connector.Curved formula connects the structure of cable connector：Curved formula, which connects cable connector front end, dielectric
Support, rear end is air section, because back air accounting is bigger, causes impedance mismatching serious, voltage standing wave(VSW) is higher.
The content of the invention
In order to solve the above-mentioned problems of the prior art, the purpose of this utility model is that providing a kind of electrical property improves
Angle connector, add insulating trip to reduce impedance, realize span line impedance matching substantially, reduce the voltage standing wave ratio of product；
The utility model is simple in construction, is easily achieved, and will not destroy the original structure of connector.
To achieve the above objectives, the utility model adopts the following technical scheme that：
The angle connector that a kind of electrical property improves, including be fixed as one inner wire 1, insulation using epoxy resin encapsulated
Son 2 and shell 3, the snap ring 5 and sealing ring 4 being arranged in the stepped hole of shell 3, the swivel nut 6 being assemblied in outside shell 3, press-in are outer
The bonnet 7 of the rearward end of shell 3, it is characterised in that：The air end of the vertical section of the inner wire 1, which is provided with, reduces connector impedance
Insulating trip 8, the external diameter of insulating trip 8 and the internal diameter of shell 3 are gap cooperation.
Gap value between the external diameter of the insulating trip 8 and the internal diameter of shell 3 is 0.03-0.1mm.
The material polytetrafluoroethylene (PTFE) of the insulating trip 8.
The structure of angle connector：There is dielectric support angle connector front end, and rear end is air section, because rear end is empty
Gas accounting is bigger, causes impedance mismatching serious, standing wave is higher.Add insulating trip 8 to reduce impedance, realize span line impedance substantially
Matching, reduce the voltage standing wave ratio of product.The utility model is simple in construction, is easily achieved, and will not destroy the original of connector
There is structure.
Brief description of the drawings
Fig. 1 is the structural representation that the curved formula of the utility model connects cable connector.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in figure 1, the angle connector that a kind of electrical property of the utility model improves, including it is inner wire 1, insulator 2, outer
Shell 3, sealing ring 4, snap ring 5, swivel nut 6, bonnet 7 and insulating trip 8.Inner wire 1, insulator 2 and shell 3 use epoxy resin encapsulated
It is fixed as one.Snap ring 5, sealing ring 4 clamp snap ring 5 with clasp forceps on the shell 3, by swivel nut 6 on shell 3.
Vertical inner wire air end puts an insulating trip 8, and (thickness of insulating trip 8 is L, can adjust insulator according to different connectors
Thickness), add insulating trip 8 to reduce impedance, realize span line impedance matching, reduce the voltage standing wave ratio of product.Finally by after
Lid 7 is pressed into shell 3, now completes the assembling of product.
The structure of angle connector：There is dielectric support angle connector front end, and rear end is air section, because rear end is empty
Gas accounting is bigger, causes impedance mismatching serious, standing wave is higher.Add insulating trip 8 to reduce impedance, realize span line impedance substantially
Matching, reduce the voltage standing wave ratio of product.The utility model is simple in construction, is easily achieved, and will not destroy the original of connector
There is structure.
As preferred embodiment of the present utility model, the external diameter of insulating trip 8 coordinates with the internal diameter of shell 3 for gap,
Gap amount is 0.03-0.1mm.
As preferred embodiment of the present utility model, the material polytetrafluoroethylene (PTFE) of insulating trip 8.
