Description
Technical field
The utility model relates to a kind of RF coaxial adapters, belongs to technical field of electronic components.
Background technology
Millimeter wave connector typically refers to the connector of operation wavelength below 10mm, is a kind of Subminiature microwave coaxial connector.Its frequency is high, physical dimension is little, required precision is high.Because physical dimension and the operation wavelength of connector is close, any small variation all likely brings serious impact to its electric property, and this has brought high-precision requirement just to the connector construction size.The connector size is little, and design and machining accuracy have just been proposed to higher specification requirement.
In the world, although it is a lot of to have released at present the millimeter wave connector kind, such as: the millimeter wave connectors such as 2.92mm, APC3.5,2.4mm.In these millimeter wave connectors, although, more than 2.92mm connector frequency can arrive 40GHz, because of poor reliability, jack easily damages; And the common frequency of utilization of 3.5mm connector does not reach 30GHz.
In existing radio frequency connector, 2.4mm connector, 2.92mm connector, 3.5mm connector, N-type etc. are all standard interfaces, and the adapter at 2.4mm switching N-type interface is to use more a kind of adapter on current tester.The radio-frequency (RF) coaxial interface that its two ends are standard, an end can be pegged graft with the 2.4mm interface, and the other end can be pegged graft with the N-type interface.
But existing this adapter, due to the restriction of size, the insulating supporting insufficient strength, cause adapter in use for some time, and the axiality variation of inner wire and outer conductor causes the 2.4mm port easily to be inserted bad.In addition, due to the insulating supporting insufficient strength, easily loosening between inner wire and insulating supporting, bad change occurs in the voltage standing wave ratio of adapter, affects product and uses.
In existing adapter, occur adopting two insulating supportings to fix inner wire, its structure as shown in Figure 1.But, eat support in order to assemble this insulation, outer conductor must be made to split-type structural, otherwise can't install and fix.But this increases adapter product component and processing cost undoubtedly.
The utility model content
The deficiency that the utility model exists for prior art just, provide a kind of adapter with a plurality of insulating supportings, meets actual operation requirements.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of adapter with a plurality of insulating supportings, comprise: inner wire, the first outer conductor, the second outer conductor and the first insulating supporting, inner wire is fixed on the first insulating supporting, the first insulating supporting is pressed into and is fixed in the first outer conductor, the first outer conductor is pressed into and is fixed in the second outer conductor, described adapter also comprises the second insulating supporting, the second insulating supporting is arranged in the second outer conductor inner chamber and can be free to slide, the first insulating supporting and the second insulating supporting support inner wire jointly, described inner wire arranges groove, and the second insulating supporting is stuck on groove.
As improvement of the technical scheme, on described the second outer conductor inner chamber, be provided with chamfering.
As improvement of the technical scheme, interference fit between described the first insulating supporting and the first outer conductor.
As improvement of the technical scheme, interference fit between described the first outer conductor and the second outer conductor.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
A kind of adapter with a plurality of insulating supportings described in the utility model, under the acting in conjunction of two insulating supportings, guaranteed the axiality between internal and external conductor, guaranteed the performances such as its voltage standing wave ratio, product structure is simple, easy to process, extend useful life, by test and actual the use, verify, meet instructions for use, implementation result is remarkable.
The accompanying drawing explanation
Fig. 1 is adapter structural representation in prior art;
Fig. 2 is adaptor structure schematic diagram described in the utility model;
Fig. 3 is the partial enlarged drawing in Fig. 2.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be adapter structural representation in prior art.Described adapter comprises: inner wire 10, the first outer conductor 20, the second outer conductor 30 and the first insulating supporting 40.Inner wire 10 is fixed on the first insulating supporting 40.Adopt interference fit between the first insulating supporting 40 and the first outer conductor 20, the first insulating supporting 40 is pressed into and is fixed in the first outer conductor 20.Also adopt interference fit between the first outer conductor 20 and the second outer conductor 30, like this first outer conductor 20 also is pressed into and is fixed in the second outer conductor 30.
As shown in Figure 1, existing adapter also comprises the second insulating supporting 50 and the 3rd outer conductor 60.The second insulating supporting 50 is arranged on inner wire 10, the second insulating supporting 50 and the first insulating supporting 40 actings in conjunction, and auxiliary inner wire 10 is fixed in the second outer conductor 30.
For the installation that realizes the second insulating supporting 50, with fixing, the second insulating supporting 50 is outside equipped with the 3rd outer conductor 60, the three outer conductors 60 and is pressed in the second outer conductor 30.Like this, utilize the 3rd outer conductor 60 that the second insulating supporting 50 is fixed on the second outer conductor 30.
As shown in Figure 2, be the real described adaptor structure schematic diagram of the utility model, Fig. 3 is the partial enlarged drawing in Fig. 2.In order to guarantee the axiality between inner wire 10 and the second outer conductor 30, the second insulating supporting 50 is set on inner wire 10, the second insulating supporting 50 is arranged in the second outer conductor 30 inner chambers and can be free to slide, such the first insulating supporting 40 and the second insulating supporting 50 actings in conjunction, auxiliary inner wire 10 is fixed in the second outer conductor 30, the axiality between assurance.
On inner wire 10, groove is set, the second insulating supporting 50 is stuck on groove, has limited like this it and has been free to slide.
For the second insulating supporting 50 successfully is installed, also be provided with chamfering 30a on the second outer conductor 30 inner chambers, by chamfering 30a, can smoothly the second insulating supporting 50 be packed into.
Adapter described in the utility model, the second insulating supporting 50 that utilization can be free to slide, and the design of corresponding groove structure, cancelled existing the 3rd outer conductor 60 structures, and its structure is simpler, and process and assemble is convenient, has reduced product cost.
The utility model is that to take the adapter at 2.4mm switching N-type interface be example, in fact, equally also a plurality of insulating supportings can be set on the adapter at other different interfaces, guarantee axiality and electric property between its internal and external conductor, but this not break away from essence of the present utility model.
