Description

The push-in type radio frequency (RF) coaxial connector

Technical field

The utility model relates to a kind of connector, relates in particular to a kind of push-in type coaxial connector that device is connected with microstrip line between the device that is used in.

Background technology

Along with the development of mechanics of communication, equipment volume such as various the army and the people's microwave communications, mobile communication, fine measuring instrument are tending towards miniaturization, microminiaturization day by day.Therefore, the connector that is used for these equipment need carry out socket in very intensive space.

General coaxial connector is made up of plug male connector (abbreviating plug as) and socket female connector (abbreviating socket as), and existing more common coaxial connector great majority adopt screw thread coupling or fast socket, connector.Wherein, screw thread coupling is by screwing the connection swivel nut, and its internal thread is connected with external screw thread on the socket, drives contact pin, insulator and shell on the plug simultaneously to socket one side shifting, and the inner wire in plug, the socket is in contact with one another, the final realization is electrically connected.But owing to must install and remove through realizing after repeatedly screwing between the plug, socket, and because of being subjected to the demand of operating space, that can not lean between the adjacent coaxial connector is too near, thereby has restricted its development to high-density installation to a certain extent.And pin connector and socket connector are connected by screw thread or special retaining mechanism, and axiality requires height, and axis tilt relatively.Need in same circuit board, install when organizing connector more, because all necessary coaxial installation of each connector, therefore, the relative position of each connector then needs very accurate, when a pair of the installation because of disalignment in many groups connector caused and can't then can cause whole group panel or equipment to install when inserting.

In sum, existing radio frequency (RF) coaxial connector is not suitable for device and is connected with microstrip line between the device.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of can realize the push-in type radio frequency (RF) coaxial connector of mounting or dismounting fast at above-mentioned prior art present situation, the microstrip line that this connector is particularly suitable for high density, little space between device and the device is connected, but also can prevent owing to the plug and socket too quickly situation of damaging connector of pegging graft mutually takes place.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of push-in type radio frequency (RF) coaxial connector, and comprising can be in device panel fixing plug body and socket; Wherein, described plug body front end has a cavity, is provided with plug insulator and contact pin in the plug body, and the head of this contact pin is positioned at described cavity; Described socket front end has the inserting column that is equipped with the insertion cavity with described cavity mutually, is provided with socket insulator and interior electric conductor in the socket, and electric conductor has the jack that inserts for described contact pin in this; It is characterized in that: in the form of a ring a reed is installed in the cavity of described plug body, this reed front portion has along circumferentially-spaced and a plurality of tabs of extending forward, the front end of each tabs has flanging, inserting column at socket is inserted under the cavity internal state of plug body, the outer peripheral face of described inserting column and the elasticity conflict mutually of flanging inwall.

The middle part of the cavity inwall of above-mentioned plug body has cannelure, the flanging of described reed inserts in the described cannelure, cooperate with the plug-in card of cannelure by flanging, can stably reed be positioned in the cavity, the more important thing is of the flanging free end restricted effect of cannelure edge to reed, prevent that flanging from becoming straight rapidly, guarantees that this flanging has enough elasticity all the time.

The rear portion of above-mentioned reed also has the in-flanges towards outer incline, is inserted under the cavity internal state of plug body at the inserting column of socket, and the front end face of described inserting column is resisted against on the described in-flanges.In-flanges also can carry out again cushioning effect to inserting inserting column in it.

The inwall of the cavity front end of above-mentioned plug body has the guiding chamfering.By the effect of guiding chamfering, even socket is installed slightly skew, when both plug together mutually, can the inserting of fine guiding socket put in place, realize blind joining.

For ease of plug body is installed on the device, the both sides of above-mentioned plug body have lug, have installing hole on the lug; For ease of socket is installed on the device, the both sides of described socket also have lug, also have installing hole on this lug.

Above-mentioned plug body can also the mode of being embedded be fixed in the device panel, plug body front end face and device panel end face, and the middle part of described socket is fixed in the device panel in the mode of being embedded.Plug body can be hidden in the device panel fully like this, and plug body front end face and device panel end face finally realize the seamless connection between device panel and the device panel.

The front end face of above-mentioned plug insulator flushes in the bottom of cavity.Guarantee that the plug insulator has enough axial lengths, better contact pin is played a protective role, and because insulator is flexible, so contact pin can be done slight skew in insulator.

The front/rear end of above-mentioned socket insulator flushes with the front/rear end of socket respectively.This socket insulator mainly is a not sensitive for damages of the interior electric conductor of protection.

The hole wall of the jack of electric conductor has two slits along symmetry on the axis direction of interior electric conductor in above-mentioned, and the front end of hole wall is run through in this slit.The front end of the jack of electric conductor is the leaf flap like this, so interior electric conductor front end has certain elasticity, even therefore contact pin has slight deflection, also can insert in the jack of interior electric conductor.

Compared with prior art, advantage of the present utility model is: it is equipped with in the form of a ring a reed in the cavity of plug body, this reed front portion has along circumferentially-spaced and a plurality of tabs of extending forward, the front end of each tabs has flanging, inserting column when socket inserts under the cavity internal state of plug body like this, the flange of spring can play a buffer-oriented effect to inserting column, even like this because socket and plug body when pegging graft mutually, overexert, inserting column can not damage socket and plug body yet, and guarantees the stability that both peg graft.
