Abstract

The invention discloses a coaxial connector which has increased elasticity of an inner conductor and excellent electrical performance, and belongs to the technical field of communication equipment. The coaxial connector comprises a housing and an inner conductor, and an outer circumferential surface of an elastic jack of the inner conductor is wrapped by an insulation sleeve. The outer circumferential surface of the elastic jack of the inner conductor of the coaxial connector is wrapped by the insulation sleeve, so that a mixed medium structure is formed between the inner conductor and the housing to achieve the purpose of symmetry of two medium-supported sides, the width of frequency of use is broadened, the voltage standing wave ratio is reduced, and at the same time, an elastic effect of an external connecting end of the inner conductor is increased, and the beneficial effect that the jack of the inner conductor is not easy to fatigue and disable is achieved. As a further improvement of the coaxial connector in the invention, an end part of the housing is provided with a bush which is lined in an outer conductor of a leaky cable during assembling, thereby ensuring that after the cable is tightly installed, a cable structure does not deform, and at the same time, the outer conductor of the cable and a rigid support are in large-area contact, and intermodulation is improved.

Description

Coaxial connector

Technical field

The invention belongs to communication equipment technical field, relate in particular to a kind of coaxial connector being connected fast with leaky cable.

Background technology

The field that leaky cable is difficult to play a role for general communication antenna, the region that particularly cannot provide enough communications to cover in mobile communcations system separate antennas, as the blind area of mountain area, hills, tunnel, subterranean railway, mine, underground structure, market or the propagation of other electromagnetic field.In these regions, due to the narrow and small of surrounding environment and stopping, antenna cover is very limited, and cover object and signal radiation direction and can provide uniform field intensity perpendicular to radiation environment owing to approaching very much, so under these environment for wireless signal receiver leakage coaxial cable be best wireless coverage means.Leaky cable had both had signal transmitting effect, had again antenna to accept function.

The coaxial connector being connected with leaky cable in the market uses frequency range to exist: DC-2.5G, growing along with mechanics of communication, requirement to frequency of utilization improves constantly, and frequency range is divided trend " height " and " narrow ", and limited system, product use the use frequency range of frequency range 5.8G at present.

Summary of the invention

For the problems referred to above, the invention provides a kind of inner wire elasticity that increases, the coaxial connector that electric property is superior, comprises shell and inner wire, on the outer circumference surface of described inner wire elastic hole, is coated with insulating case.

The outer circumference surface of the inner wire elastic hole of coaxial connector of the present invention puts insulating case, make to form blending agent structure between inner wire and shell and reach the object of dielectric support double-sided symmetrical, broadening frequency of utilization width, reduce voltage standing wave ratio, increase the elastic effect of the external link of inner wire simultaneously, reach the jack indefatigability of inner wire and the beneficial effect of inefficacy.

Further improve as the present invention, the end of described shell is lining into the lining in leaky cable outer conductor while being provided with attaching, after guaranteeing that like this cable loads, can not produce distortion to the construction of cable, cable outer conductor contacts with rigid support large area simultaneously, improves intermodulation.

Accompanying drawing explanation

Accompanying drawing is coaxial connector of the present invention and leaky cable connection diagram.

Embodiment

Below in conjunction with accompanying drawing, the present invention is made and being further illustrated.

As shown in the figure, a kind of coaxial connector, comprises shell 1 and inner wire 2, is coated with insulating case 3 on the outer circumference surface of described inner wire elastic hole.

The outer circumference surface of inner wire 2 elastic hole of coaxial connector of the present invention puts insulating case 3, make to form between inner wire 2 and shell 1 air and insulator blending agent structure, reach the object of dielectric support double-sided symmetrical, broadening frequency of utilization width, reduce voltage standing wave ratio, increase the elastic effect of the external link of inner wire simultaneously, reach the jack indefatigability of inner wire and the beneficial effect of inefficacy; The end of shell 1 is lining into the lining 5 in leaky cable outer conductor 4 while being provided with attaching, after guaranteeing that like this cable loads, can not produce distortion to the construction of cable, and cable outer conductor contacts with rigid support large area simultaneously, improves intermodulation.By above measure, coaxial connector of the present invention reaches, voltage standing wave ratio VSWR≤1.18, third order intermodulation PIM≤-155dBc (20W), the requirement of high frequency (DC-6G).

The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.

Claims

1. a coaxial connector, comprises shell and inner wire, it is characterized in that: on the outer circumference surface of described inner wire elastic hole, be coated with insulating case.

2. coaxial connector according to claim 1, is characterized in that: the end of described shell is lining into the lining in leaky cable outer conductor while being provided with attaching.
