Description
Technical field
The utility model relates to the electronics field, the female radio frequency connector of particularly a kind of waterproof N type.
Background technology
Electronics industry is faced with the challenge of electronic system anti-interference problem all the time.Along with the extensive use of electronic equipment, and modern electronic equipment is accurate day by day, complicacy and multifunction, and electromagnetic interference and radio frequency interference problem are serious day by day, it can make equipment performance generation minor variations, weaken, even cause the malfunctioning fully of equipment.Particularly communication, medical field can cause communication disruption, instruction mistake to send out, so that cause great economic loss even jeopardize personal safety if electronic equipment is interfered.
With regard to a system, various electromagnetic interference are the most serious at interface, and the EMI that it can be outside with system conducts or is radiated internal system, can the EMI of internal system be conducted or be radiated the system outside again.Therefore, the connector of interface plays an important role in anti-electromagnetic interference.For adapting to these new situations and the instructions for use of satisfying the user, we plan to develop a series of radio frequency connectors, are used for the signal transmission of holding wire, power line, play the effect of anti-electromagnetism, radio frequency interference simultaneously.
The operational environment of some radio frequency connector is outdoor in addition, or worse workplace, like seawater, chemical industry, space flight or the like; The interference of electromagnetism is not only arranged, also exist the disturbing factor of water, or even have corrosive liquid; Even if indoor, owing to the temperature of climatic environment, the variation of humidity, airborne hydrone can produce condensation in the metal surface; Traditional radio frequency connector mostly is provided with waterproof grommet in a public female junction; To joining under the state of tightening just concrete water-proof function, for highly sensitive, lower powered transmission signal, in case receive the influence of water; Then can produce signal attenuation and short circuit phenomenon, so traditional connector female head is the waterproof requirement that can not satisfy the IP67 grade.
Summary of the invention
To the problem of above-mentioned existence, the utility model aims to provide the female radio frequency connector of a kind of waterproof N type according to the fire resistance characteristic of radio frequency connector.
The utility model solves the technical scheme that its technical problem adopted: the female radio frequency connector of a kind of waterproof N type; Comprise nut, internal tooth packing ring, sealing gasket, shell, inner wire, insulator and line ball cover; Described shell is a D shape tubulose external screw thread body; One circular step is arranged at its bottom, and the plane is provided with annular on step
The sealing gasket groove, plane, D shape tubulose external screw thread side is a milling flat; Be provided with the insulator limited step at D shape tubulose external screw thread body internal diameter; Described insulator comprises insulator A and insulator B, and insulator A is a tubular body, and end face is provided with a concentric circular step above that, and its lateral surface is provided with annular seal ring A groove; Insulator B is stairstepping in a tubular form.
Insulator A and insulator B be coaxial to be placed within the shell in the hole mutually, between insulator A and insulator B, is provided with annular seal ring B;
Be provided with the funnel-form gland at the rear portion of insulator B, the end of gland and line ball are locked and are connected;
Inner wire is that two end hollow center are the cylinder of entity, and side axial in the top has the U font groove more than, and a radial perforation is arranged in the side of its lower end, and inner wire is tight fit through insulator A with insulator B endoporus and is connected;
Described shell, inner wire, gland and line ball cover are metal material, and insulator A and insulator B are non-metallic material, and sealing gasket, sealing ring A and sealing ring B are a kind of material of rubber, latex, silica gel.
The utility model has changed conventional radio frequency connector Design Mode; Between the outside and D shape tubulose external screw thread body inwall of insulator A, be provided with sealing ring A and sealing ring B between insulator A and the insulator B; Intercepted the infiltration of water effectively; Thereby improved the interference free performance of product, guaranteed the stability that product uses, can be widely used in fields such as ocean, space flight, military project, chemical industry, electromechanics, communication.
