Abstract
The utility model relates to a connector of a DIN radio frequency device; a connector body is connected and fixed together with a cavity through a connector installing flange; a convex ring is arranged on the end surface of the flange installing end surface where the installing flange is contacted with the cavity; the convex ring is arranged at the periphery of a metal penetrating part; and the convex ring is concentric with the metal penetrating part. The utility model discloses a DIN connector which is more excellent in structure and electrical index and can improve the third order intermodulation superiority of a passive device.
Description
Technical field
The utility model relates to employed connector in a kind of communication, the radar.
Background technology
Radio frequency connector is that conductor is connected with suitable pairing device, realizes the electromechanical compo that microwave signal switches on and off.In signal transmission pathway, be blocked between place or the isolated obstructed device, erect the bridge of communication, thereby make the signal circulation, make the microwave path realize intended function.Radio frequency connector is indispensable parts in the passive device.Radio frequency connector form and structure are Protean, along with differences such as application, frequency, power, applied environments, various multi-form connectors are arranged.On mobile communication engineering often utilization have N type and two kinds of radio frequency connectors of DIN type wherein the frequency range that is suitable for of N type be 0 ~ 11GHz, be used for the coaxial cable connector with threaded connection of middle low power.This is a kind of connector that is most widely used in the indoor distribution, possesses the good mechanical performance, can cooperate most feeder line to use.The frequency range that DIN type connector is suitable for is 0 ~ 11GHz, compares N type radio frequency connector, and DIN type connector can carry bigger input power.So generally be used for macro base station radio frequency delivery outlet.DIN type connector mounting flange left-hand component is standard DIN type FEMALE connector, it have feeder line DIN type MALE both can closely be connected to form the path of signal by screw thread.The right of mounting flange is a metal part through walls, its size and the manhole size above the passive device cavity match, radio frequency connector is installed on the passive device cavity, and, radio frequency connector closely is connected with passive device with screwed hole above the cavity by the installing hole on the mounting flange.Guarantee the fastness of connector on cavity.But the device that processing is returned is made before the finished product, and the outer surface of device all can be done some surface treatments, such as plastic-blasting, and baking vanish etc.Because the requirement of the third order intermodulation index of device, will fully contacting with the contacted part of cavity of mounting flange will be conduction state between the two, but the processing method of plastic-blasting and baking vanish all can make the surface insulation of device, influences the electric index of device.
The utility model content
The utility model is at the deficiencies in the prior art, provide a kind of structurally with electric index on more excellent, improve the DIN type connector of passive device third order intermodulation superiority.
The utility model is achieved through the following technical solutions:
A kind of connector of DIN type radio-frequency devices, connector body and cavity are connected and fixed by the connector mounting flange, and the contacted mounting flange end face of described mounting flange and cavity is provided with projection.
A kind of connector of DIN type radio-frequency devices, described projection are bulge loop, and described bulge loop is arranged on the periphery of metal part through walls.
A kind of connector of DIN type radio-frequency devices, described bulge loop is concentric with metal part through walls.
The utility model increases annular small stair at the DIN of original structure type radio frequency connector and passive device surface contact-making surface, the height of small stair is greater than the thickness of plastic-blasting and the increase of baking vanish appearance, and the adpting flange of connector can effectively contact with housing surface by boss like this.Can avoid like this because the phenomenon that connector that the outward appearance processing causes and cavity contact-making surface can not conduct electricity.This utility model has bigger conductive contact surfaces compared with original connector, thereby improves the third order intermodulation index of device.
Description of drawings
Fig. 1 is the sectional structure schematic diagram.
Fig. 2 is connector and cavity junction enlarged drawing.
Embodiment
Shown in accompanying drawing 1,2.The connector of the utility model DIN type radio-frequency devices, connector body 1 is connected and fixed by connector mounting flange 2 with cavity 3, and mounting flange 2 is provided with bulge loop 4 with cavity 3 contacted mounting flange end faces.Bulge loop 4 is arranged on the periphery of metal part 5 through walls.Bulge loop 4 and metal part through walls 5 is concentric.The utility model increases bulge loop 4 at the DIN of original structure type radio frequency connector 1 and passive device surface contact-making surface, the height of bulge loop 4 is greater than the thickness of plastic-blasting and the increase of baking vanish appearance, and the adpting flange 2 of connector 1 can effectively contact by bulge loop 4 and cavity 3 surfaces like this.Can avoid like this because the phenomenon that connector 1 that the outward appearance processing causes and cavity 3 contact-making surfaces can not conduct electricity.This utility model has bigger conductive contact surfaces compared with original connector, thereby improves the third order intermodulation index of device.
Claims (3)
1. the connector of a DIN type radio-frequency devices, connector body and cavity are connected and fixed by the connector mounting flange, it is characterized in that the contacted mounting flange end face of described mounting flange and cavity is provided with projection.
2. the connector of a kind of DIN type radio-frequency devices according to claim 1 is characterized in that described projection is a bulge loop, and described bulge loop is arranged on the periphery of metal part through walls.
