Abstract
Provided is a coaxial connector with high third-order performance, comprising a center conductor, a main housing arranged outside the center conductor, and an insulating support located between the center conductor and the main housing, wherein the wiring crimping position of the main housing is externally provided with a crimping sleeve. The coaxial connector is characterized in that the center conductor adopts a DIN type structure; and the front end face of the insulating support is provided with a compensation groove while the rear end face of the insulating support is provided with a tank at the inner side. Compared to the prior art, the center conductor of the coaxial connector of the utility model adopts a DIN type structure, thereby decreasing the external diameter of the center conductor, making the structure of the connector more compact, and accordingly reducing the product cost. Moreover, the center conductor can be assembled forward from the tail of the main housing, thereby facilitating the assembling. In addition, the compensation groove arranged at the front end face of the insulating support and the tank arranged at the rear end face of the insulating support reduce the weight of the component, cut the product cost, and facilitate the installation of the insulating support.
Description
Technical field
The utility model relates to a kind of coaxial cable connector, specifically refers to a kind of coaxial cable connector with Senior Three rank performance, is applicable to the connection of radio frequency unit intermodule.
Background technology
In the communications industry, coaxial cable connector is used for the connection of radio frequency unit intermodule, and it mainly comprises center conductor, is wrapped in the outer insulating supporting of center conductor and is installed in the outer main body cover of insulating supporting.Mainly there is the defective of following two aspects in existing coaxial cable connector: at first, the structure of its insulating supporting and main body cover is optimized not, causes the heavy and relatively large defective of volume of overall weight of coaxial connector, is unfavorable for reducing product cost; Secondly, its center conductor generally adopts Split type structure, and inside diameter is larger, so that the overall structure of coaxial connector is compact, small and exquisite not, corresponding cost is just higher, and operation is more, more loaded down with trivial details during assembling, and performance also is difficult to debugging.Obviously, along with the fast development of the communications industry, model change is rapid, and above-mentioned this coaxial connector more and more is not suitable for the demand of modern communications development, thereby, remain to be proposed a kind of new coaxial cable connector.
The utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, and the coaxial cable connector that a kind of cost is lower, assembling comparatively simply has Senior Three rank performance is provided.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this has the coaxial cable connector of Senior Three rank performance, comprise center conductor, be located at the outer main body cover of center conductor and the insulating supporting between center conductor and main body cover, peripheral hardware has crimping sleeve at the wiring crimping position of described main body cover, it is characterized in that: described center conductor adopts DIN type structure, have a compensating tank on the front end face of described insulating supporting, the rear end face inboard of this described insulating supporting has a deep gouge.
For the weight that further alleviates coaxial connector and reduce its cost, described main body cover has flange, has cannelure on the rear end face of this flange.
Preferably, the wiring crimping position of described main body cover is provided with escape.Escape carries out screens when being used for stepping down of hobboing cutter and crimping.
Further preferred, the wiring crimping position of described main body cover is provided with annular knurl.Annular knurl can improve the reliability of crimping.
Damage shell by pressure during for fear of crimping, on main body cover, be provided with the boss that blocks described crimping sleeve near described wiring crimping position.
Further preferred, described main body cover inside is provided with the compensation ledge structure that can improve the coaxial connector performance.
Compared with prior art, the utility model has the advantage of: at first, the center conductor of this coaxial cable connector adopts the DIN type structure of remodeling, not only can reduce center conductor external diameter, make the structure of connector more compact, small and exquisite, thereby reduction product cost, but also center conductor is assembled forward from the main body cover afterbody, make assembling become more easy; Secondly, the deep gouge of being located at the compensating tank of insulating supporting front end face and being located at the insulating supporting rear end face also is convenient to the installation of insulating supporting when alleviating pts wt and reducing product cost.
Description of drawings
Fig. 1 is the partial sectional view of the utility model embodiment;
Fig. 2 is the partial exploded view (removing cable) of Fig. 1.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, coaxial cable connector in the present embodiment comprises main body cover 1, center conductor 2, insulating supporting 3 and crimping sleeve 4, insulating supporting 3 is located at outside the center conductor 2, main body cover 1 is wrapped in the outside of insulating supporting 3,4 of crimping sleeves are crimped on the wiring crimping position of main body cover 1, after assembling was finished, crimping sleeve 4 was crimped into regular hexagon, and the head at wiring crimping position is equipped with cable.The parameter index of the coaxial cable connector of present embodiment is as follows: frequency of utilization 0-2.2Ghz, standing wave 0-2.2Ghz, standing wave is less than 1.15, third order intermodulation is less than-105dBm, this coaxial cable connector is not reducing reliability and is not affecting on the basis of performance, can reduce the quantity of part and alleviate the weight of whole coaxial connector, thereby reach the purpose that reduces product cost.
Particularly, center conductor 2 adopts DIN type modified structures, adopt this structure after, can make the structure of center conductor 2 more succinct on the one hand, so that the structure of whole coaxial connector is compacter, small and exquisite, to reach the purpose that reduces cost; Can also play on the other hand the effect that improves frequency of utilization.In addition, after center conductor 2 adopts DIN type modified structure, center conductor 2 external diameters are reduced, center conductor 2 can assemble forward from main body cover 1 afterbody, make center conductor 2 have to adopt the defective of Split type structure to avoid crossing minor issue because of the hole of insulating supporting 3, thereby the three rank performances (PIM index) that guaranteed coaxial connector are not affected.Present embodiment is except center conductor 2 adopts DIN type modified structure, also the structure of insulating supporting 3 and main body cover 1 is optimized, particularly, front end face at insulating supporting 3 has compensating tank 31, rear end face at insulating supporting 3 has deep gouge 32, and this compensating tank 31 is when being optimized the coaxial connector performance, and this deep gouge 32 is not affecting 2 fixed whiles of center conductor, all can effectively alleviate the weight of part, and be convenient to the installation of insulating supporting 3.Main body cover 1 has flange near described wiring crimping position, has cannelure 12 on the rear end face of this flange, thereby the overall weight of coaxial connector is reduced, to reach the purpose that reduces cost.In addition, in order to satisfy the high performance requirements of product, present embodiment also is provided with compensation ledge structure 11 in the inside of main body cover 1.
