A kind of DIN type radio frequency connector

Technical field

The utility model relates to cavity power splitter field, specifically is a kind of DIN type radio frequency connector.

Background technology

The connector of radio-frequency devices (radio frequency connector) is that conductor (line) is connected with suitable pairing device, realizes the electromechanical compo that microwave signal switches on and off.Indispensable parts in the passive device.That often uses on mobile communication engineering has N-type and two kinds of radio frequency connectors of DIN type, and wherein, N-type is applicable to the coaxial cable connector with threaded connection of middle low power, is a kind of connector that is most widely used in the indoor distribution; A kind of DIN type radio frequency connector is compared the N-type radio frequency connector, and DIN type radio frequency connector can carry bigger input power, and powerful power must be used DIN die cavity body power splitter along separate routes.The inner wire of existing DIN type radio frequency connector is to be fixed in the housing of radio frequency connector, namely require the merit of inner wire and DIN die cavity body power splitter to divide the length of excellent coupling part must satisfy 2 requirements: 1, inner wire reaches the outer length of housing to be satisfied it and can divide rod fixedly connected with merit; The metal of 2, DIN type connector shell thread part through walls accurately cooperates with the cavity installation site of DIN die cavity body power splitter.During but practical operation is installed, the distance between the DIN type radio frequency connector installation site is divided into plurality of specifications on rod and the cavity because merit is divided, when the distance between the connector installation site increases on merit branch rod and the cavity, will cause that inner wire is inner to divide with merit that the generation certain clearance can not interconnect between the rod, the technical staff is in order to address this problem, just need divide in inner wire and merit increases by an adapter both can be connected between the rod, during installation, adapter need be installed on merit earlier divides on the rod, and then DIN type radio frequency connector is installed on the cavity, and inner wire is connected with adapter, but in producing, the axle center of adapter and inner wire can produce certain error, and it is inaccurate to cause being connected of inner wire and adapter to cooperate, thereby influences the signal transmission effect of DIN type connector.

The utility model content

The technical problems to be solved in the utility model provides a kind of DIN type radio frequency connector, and its inner wire can be installed separately with housing, and the installation site is accurate, and can change the inner wire of different length according to different dimensional requirements.

The technical solution of the utility model is:

A kind of DIN type radio frequency connector, include housing and be arranged at the interior inner wire of housing, the inner and the outer end of described housing are hatch frame, the inner end of housing sidewall is metal thread part through walls, the outer end of housing sidewall is international thread part, described inner wire inner end is to reach the outer boss structure of housing, and the outer wall of boss structure is provided with external screw thread, enclosure interior is set with locating ring, and the part that the inner wire outer wall contacts with the locating ring inwall is that smooth surface makes its telescopic moving in the enclosure.

The inner face of described locating ring offsets with step surface on the outer casing inner wall and fixedlys connected, and described inner wire outer wall is provided with limited step, and the step surface that inner wire passes locating ring and its limited step is against on the outer face of locating ring.

The outer face of described inner wire is provided with the spanner location notch

The cross section race diameter of described metal thread part through walls is 10-20mm.

Advantage of the present utility model:

(1), inner wire of the present utility model and housing are split-type structural, during installation, can be earlier the housing of DIN type radio frequency connector be installed on the cavity of DIN die cavity body power splitter, inner wire passes DIN type radio frequency connector housing and merit and divides rod to be connected then, because the perforation axle center of the inner wire on the DIN type radio frequency connector housing and merit are divided the axis coinciding of the installing hole on the rod, guaranteed that inner wire and merit divide excellent link position accurate, thereby guaranteed the effect of DIN type radio frequency connector signal transmission;

(2), the distance between the DIN type radio frequency connector installation site is divided into plurality of specifications on rod and the cavity because merit is divided, the utility model can select for use the inner wire of different length to cooperate installation to get final product according to the actual range in both installations;

(3), the cross section race diameter of the metal of existing DIN type radio frequency connector thread part through walls is generally 21mm, accordingly just require the cavity size of DIN die cavity body power splitter to cooperate with it, the diameter that is connector installing hole on the cavity is 21mm, cooperate installation with regard to the large-sized cavity body structure of the special production of needs with DIN type radio frequency connector, thereby increased the cost of producing DIN type power splitter; Owing to adopted bigger cavity of power distributor, according to designing requirement, the merit in the cavity of power distributor is divided the also corresponding overstriking of excellent size, when having increased cost, has increased the Insertion Loss of cavity power splitter, has influenced the electricity function index of DIN type power splitter in addition; The cross section race diameter of the utility model metal thread through walls is 10-20mm, select for use the cavity of existing N-type cavity power splitter to cooperate installation to get final product, need not to produce large-sized cavity body structure specially, reduced processing cost, also reduced the Insertion Loss of DIN die cavity body power splitter simultaneously;

The utility model is simple in structure, size is little, the merit of existing N-type cavity power splitter can be divided rod and cavity to be connected the back with the utility model and form DIN die cavity body power splitter, saved the production cost of DIN die cavity body power splitter, simultaneously easy for installation, and inner wire and merit are divided excellent good connecting effect, guarantee the effect of DIN type radio frequency connector transmission signal, possessed present N-type cavity power splitter superior electricity function index and third order intermodulation index.
