Abstract
A kind of big torque embedding structure of radio frequency (RF) coaxial connector, including the groove opened on the vertical core and inner wire opened on insulator outer conductor along same radial direction with insulator and outer conductor along same radial direction, also include the ratio channel section that the groove on inner wire is further opened into inner wire and accumulate small blind hole, epoxy glue injection inner wire in the blind hole of the groove and inner wire of insulator and outer conductor with forming big torque embedding structure；Vertical core during assembling by this blind hole to quasi-insulator outer conductor, such epoxy glue will be flowed into the blind hole of inner wire groove；No longer it is contact of the simple axle with hole after epoxy adhesive curing, between inner wire groove and epoxy glue, but epoxy pin is inserted in the blind hole of inner wire groove.The structural strength of epoxy pin is so must pull against, application torque fractures to epoxy pin and can just make rotation of inner conductor.So the structure obtains larger torque, meet and required as defined in standard.
Description
Technical field
The utility model belongs to radio frequency coaxial electric connector technical field, and in particular to a kind of radio frequency (RF) coaxial connector is with greatly
Torque embedding structure.
Background technology
Radio frequency (RF) coaxial connector be it is a kind of obtain commonly used electronic component, product be widely used in weaponry,
The microwave communication system regions such as test system.And the connector (such as Fig. 1) with epoxy resin encapsulated structure, it is a kind of conventional
, Exemplary connectors structure, frequently appear in microband connector, adapter and connect in the connectors such as cable connector.It is
Reserved at the inner wire of connector and a vertical core is reserved on groove (A sections in Fig. 1), insulating supporting and outer conductor, by groove with erecting
After the alignment of hole, then epoxy glue injected, after epoxy adhesive curing, form epoxy resin pin, ensure that between above-mentioned three not
Axial float, do not rotated between insulating supporting and outer conductor.
There is a fixed index request of central contact in connector standards, the index request connector can not only
Meet the requirement for axially retaining power, the torque request that radial direction applies also is disclosure satisfy that, due to epoxy resin encapsulated structure
Anti-rotation strength between insulating supporting and inner wire relies primarily on the hole table of inner wire groove, inner wire axle surface and casting glue
Frictional force between face carries out anti-rotating, therefore torque is smaller, can not meet index request as defined in standard.
The content of the invention
In order to overcome above-mentioned prior art defect, the purpose of this utility model is that providing a kind of radio frequency (RF) coaxial connector uses
Big torque embedding structure so that after connector embedding, there is larger torque, can meet that central contact is fixed and want
Ask.
To reach above-mentioned purpose, the utility model uses following technical scheme：
A kind of radio frequency (RF) coaxial connector with big torque embedding structure, including insulator 2 and outer conductor 3 along same radial direction
The groove opened on the vertical core and inner wire 1 opened with insulator 2 and outer conductor 3 along same radial direction, in addition on inner wire 1
The ratio channel section further opened into inner wire 1 of groove accumulate small blind hole 1-1, epoxy glue injection inner wire 1 and insulator 2
Big torque embedding structure is formed with the groove of outer conductor 3 and the blind hole 1-1 of inner wire 1；This blind hole 1-1 is aligned absolutely during assembling
The vertical core of edge 2 and outer conductor 3, such epoxy glue will be flowed into the blind hole 1-1 of the groove of inner wire 1.After epoxy adhesive curing,
No longer it is contact of the simple axle with hole between inner wire groove and epoxy glue, but epoxy pin inserts inner wire groove
In the blind hole at place.The structural strength of epoxy pin is so must pull against, application torque to epoxy pin, which fractures, can just make interior lead
Body rotates.So the structure obtains larger torque, meet and required as defined in standard.
Brief description of the drawings
Fig. 1 is existing radio frequency (RF) coaxial connector epoxy resin encapsulated structural representation.
Fig. 2 is the big torque epoxy resin encapsulated structural representation of radio frequency (RF) coaxial connector.
Embodiment
RF coaxial connector is further illustrated with big torque embedding structure below in conjunction with the accompanying drawings.
A kind of big torque embedding structure of radio frequency (RF) coaxial connector, it is that (processing one is small blind by inner wire groove point nest
Hole), this blind hole is directed to the vertical core of insulating supporting and outer conductor, such epoxy glue will flow into the blind of inner wire groove during assembling
In hole.No longer it is contact of the simple axle with hole after epoxy adhesive curing, between inner wire groove and epoxy glue, but epoxy
Pin is inserted in the blind hole of inner wire groove.The structural strength of epoxy pin is so must pull against, applies torque to epoxy
Pin, which fractures, can just make rotation of inner conductor.So the structure obtains larger torque, meet and required as defined in standard.
Concrete structure is as shown in Fig. 2 a kind of big torque embedding structure of radio frequency (RF) coaxial connector, including insulator 2 and outer
Opened on the vertical core and inner wire 1 opened on conductor 3 along same radial direction along same radial direction with insulator 2 and outer conductor 3 recessed
The ratio channel section that groove on groove, in addition to inner wire 1 is further opened into inner wire 1 accumulates small blind hole 1-1, epoxy glue note
Enter in the inner wire 1 and blind hole 1-1 of the groove and inner wire 1 of insulator 2 and outer conductor 3 and form big torque embedding structure.
In simple terms, this programme is that original vertical core is only changed into inner wire, insulation branch on insulating supporting, outer conductor
Support, outer conductor three have vertical core, so anti-rotation effect can be played.This programme is that solve the torque of epoxy resin encapsulated connector not
Most simple, effective scheme up to standard.
The utility model has the features such as processing is simple, cost is low, positive effect, smaller on electric property influence, is city
On field the epoxy resin encapsulated structure resisting torque of main flow provide effectively, easily scheme, there are boundless market prospects.
