Abstract
The utility model relates to the mechanical field, and especially relates to an isolated radio-frequency coaxial connector structure. The structure comprises a connector body and an installation housing. The connector body and the installation housing are partitioned by an insulator between the connector body and the installation housing. The structure also comprises an insulating pin which passes through the connector body, the insulator, and the installation housing. A rivet for preventing axial endplay is disposed between the connector body and the insulator. A rivet for preventing axial endplay is disposed between the insulator and the installation housing. An insulating material is made of polytetrafluoroethylene. The outer layer of the insulating material is a hard shell. The hard shell is a metal layer. Compared with the prior art, the utility model employing the above technical scheme has the beneficial effects that insulators are disposed between the connector body, a case, and a cabinet, thereby completing eliminating the mutual interference between a connector system signal and an external signal, and improving the quality of signal transmission of the whole communication system; and the metal housing is added to the exterior of the insulators, thereby improving the reliability of the installation of a connector.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of radio frequency (RF) coaxial connector structure of isolation.
Background technology
Radio frequency (RF) coaxial connector is widely used in the every field such as microwave communication, military project weapon and space flight and aviation system, has the advantages such as easy to connect, easy maintenance.
The every field such as microwave communication at present,, military project weapon and space flight and aviation system are more and more higher to the requirement aspect electromagnetic compatibility when signal transmission, exchange.General connector is arranged on the housings such as cabinet, rack, because the shell of connector is directly connected with the housing such as cabinet, rack, thereby cause some the otiose signals on the housings such as cabinet, rack to interfere with the signal that connector system is transmitting, cause unnecessary signal to disturb, occur the phenomenons such as distorted signals, loss.And each connector system is connected by housings such as cabinet, racks, also cause phase mutual interference between signal that these connector systems transmit.
Utility model content
Utility model object: the utility model is in order to solve the weak point in above-mentioned technical background, a kind of radio frequency (RF) coaxial connector structure of isolation is provided, its structural reliability is high, and level of isolation is high, can effectively solve the problem of the phase mutual interference between various signals.
In order to reach as above object, the utility model is taked following technical scheme:
A kind of radio frequency (RF) coaxial connector structure of isolation, it is characterized in that, comprise connector body and mounting casing, between described connector body and mounting casing, having insulator that the two is kept apart to described insulating barrier is two-layer or three layers, and it can all contain metal shell separately.
The further technical scheme of the utility model is, also comprises insulation pin, and it penetrates connector body, insulator, mounting casing.
The further technical scheme of the utility model is between connector body and insulator, there is the riveting of turning over that prevents axial endplay.
The further technical scheme of the utility model is between described insulator and mounting casing, there is the riveting of turning over that prevents axial endplay.
The further technical scheme of the utility model is, described insulating material is polytetrafluoroethylene.
Adopt as above the utility model of technical scheme, with respect to prior art, there is following beneficial effect: between the housings such as connector body and cabinet, rack, add one deck insulator, can fully isolate the phase mutual interference between connector system signal and outer signals, thereby improve the signal Transfer Quality of whole communication system.At insulator added metal shell, can improve the reliability that connector is installed.
Accompanying drawing explanation
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the structural representation of utility model;
Wherein: 1 connector body; 2 insulators; 3 mounting casings; 4 insulation pins.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
A radio frequency (RF) coaxial connector structure for isolation, is characterized in that, comprises connector body 1 and mounting casing 3, between described connector body 1 and mounting casing 3, has insulator 2 that the two is kept apart.Also comprise insulation pin 4, it penetrates connector body 1, insulator 2, mounting casing 3.Between connector body 1 and insulator 2, there is the riveting of turning over that prevents axial endplay.
Between described insulator 2 and mounting casing 3, there is the riveting of turning over that prevents axial endplay.
Described insulating material is polytetrafluoroethylene.The material at this place is preferably, but not as restriction.
Described insulating material skin has one deck duricrust.Described duricrust is metal level.The metal level at this place is preferred hard formation, not as restriction.
Effectively the signal of extraneous signal and connector transmission itself is kept apart, or the signal of connector itself is isolated from the outside out, realize this purpose, connector body and other equipment will be kept apart.Specific practice: add one deck insulator in original connector body 1 outside, be used for completely cutting off extraneous signal; Because insulating material is softer when mounted, so add again layer of metal shell in insulator outside.
In addition, if in order to guarantee isolation effect, described insulating barrier can be two-layer or three layers, and it can all contain metal shell separately.
With reference to accompanying drawing, the utility model and the different structure of connector in the past, mainly at the outer increase insulator 2 of connector body 1, insulator increases mounting casing 3 outward, between connector body 1, insulator 2, mounting casing 3, pack insulation pin 4 into, effect is the mutual rotation preventing between connector body, insulator, mounting casing three again.Connector body is to the riveting of turning up, and mounting casing inwardly turns over riveting, prevents from mutually moving axially between connector body, insulator, mounting casing, and connector body, insulator, mounting casing become one like this, thereby realizes a kind of new connector construction.
more than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
