Abstract
The utility model relates to a detachable SMA cable assembly which comprises an internal conductor connected with microwave modules. The internal conductor is cooperatively connected with one end of a flange, and the other end of the flange is connected with a coaxial cable. As a microwave insulator is connected with the flange in the utility model, an original connection mode by the use of a SMA negative head and a SMA positive head is avoided, and connection reliability of the microwave modules is greatly raised. The detachable SMA cable assembly occupies a small space, has stable performance, and has great advantages on microwave system miniaturization development.
Description
Technical field
The utility model relates to the microwave signal transmission field, relates in particular to a kind of dismountable SMA cable assembly.
Background technology
Used multiple microwave module in electronic product, connection for this microwave module needs a large amount of coaxial cables, at present, as shown in Figure 1, the structure of tradition SMA cable assembly is: coaxial cable 1 is connected with positive 2 of SMA, cloudy 4 device of SMA is on microwave module 5, and cloudy 4 of described SMA and SMA sun 2 is threaded, and on positive 2 of SMA, nut 3 also is set.But this syndeton size is larger, and especially the bending radius of coaxial cable is larger, takies larger installing space, makes space availability ratio lower, is unfavorable for the requirement of microwave system miniaturization, lightness.In order to solve the above-mentioned larger problem that takes up room, use SMP cable or SMP connector instead, although taking up room of SMP cable or SMP connector is less, difficulty is installed, dependability is low.
The utility model content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of dismountable SMA cable assembly simple in structure, easy for installation is provided, and has advantages of that reliability is high, it is little to take up room, stable performance.
The technical scheme that the utility model adopts is as follows:
A kind of dismountable SMA cable assembly, comprise the inner wire be connected with microwave module, and an end of inner wire and ring flange is connected, and the other end of ring flange is connected with coaxial cable.
Its further technical scheme is:
Described ring flange has groove, in groove, arranges insulating material and outer conductor;
Described inner wire is isolator, and the aperture of isolator is
Mm, isolator adopts gold-plated beryllium-bronze to make;
Outer conductor is cylindrical, has the installing hole suitable with described inner wire aperture in outer conductor, and outer conductor is made by the filled gold copper product;
Described insulating material is polytetrafluoroethylene;
Groove is circular recess.
The beneficial effects of the utility model are as follows:
The utility model adopts the type of attachment of isolator and ring flange, avoided adopting the type of attachment of positive of the cloudy head of SMA and SMA in the past, greatly improved the connection reliability between microwave module, little, the stable performance that takes up room has greater advantage in microwave system miniaturization development.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is traditional SMA cable assembly syndeton.
Fig. 2 is the structural representation that in the utility model, ring flange is connected with cable.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 4, the utility model comprises the inner wire 501 be connected with microwave module 5, and inner wire 501 is isolator, and the aperture of isolator is
Mm, isolator adopts gold-plated beryllium-bronze to make.Inner wire 501 is connected with an end of ring flange 201, as shown in Figure 2, ring flange 201 has groove 204, as shown in Figure 3, groove 204 is circular recess, in the two ends up and down of groove 204, is positioned on ring flange 201 and also has screw mounting hole 205, for ring flange 201 is corresponding with the installing hole on microwave module 5, and connect by securing member.Arrange insulating material 203 and outer conductor 202 in groove 204, insulating material 203 is polytetrafluoroethylene, and outer conductor 202 is cylindrical, has the installing hole suitable with described inner wire 501 apertures in outer conductor 202, and outer conductor 202 is made by the filled gold copper product.The other end of ring flange 201 and coaxial cable 1 welding.
Concrete connection procedure of the present utility model is as follows:
As shown in Figure 4, the ring flange 201 of device cable 1 is fixed on microwave module 5 by securing member, wherein the outer conductor 202 in ring flange 201 is connected with the inner wire 501 on microwave module 5, and installation connects reliable, quick and convenient.
The closure of the blue dish 201 of arrow notation and microwave module 5 in Fig. 4, the diameter of above-mentioned outer conductor 202 can be changed according to practical condition, with the inner wire 501 of adaptive different model.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that, without prejudice to basic structure of the present utility model, the utility model can be done any type of modification.
