Description

A kind of F-type connector

Technical field

Radio frequency connector field is the utility model is related to, more particularly to a kind of F-type connector.

Background technology

Radio frequency connector is generally installed in a kind of element on cable or on instrument, belongs to the production of electromechanical integration Product, to realize the original paper of transmission line electrical connection, separation or the switching of different type transmission line.Play bridge beam action.In radio frequency In circuit, stable predetermined impedance and electric capacity are such as kept, or needs to shield extraneous electrical Interference, that just must be with coaxially connecting Device is connect to interconnect.Coaxial connector supplies in communication and electronic equipment institute adapted radio-frequency transmission line to connect radio frequency coaxial-cable, or together Axle and micro-strip, the coaxially connection between waveguide.Its plug portion is often arranged on cable socket, and socket part is often arranged on and set On standby fixed cell.

This type F-type connector in the market, the conventional design of inner center P IN needle constructions typically use frequency range 0-2GHz is can only achieve, more than 2GHz losses will become big, can not meet the needs of existing market 4G frequency ranges (0-2700MHz). Though some design losses are smaller in addition, can meet the needs of 4G frequency ranges in performance.But according to PN-EN 61169-24:2009 Standard, Φ 0.635, Φ 0.850, Φ 1.136 probe push-in F heads, thrust are both needed to be less than 20N, tried through two with thrust meter After testing circulation, three kinds of probes, which exit, to be both needed to be not less than 30g, can not also meet the market demand.

Therefore be badly in need of one kind and both met frequency range performance requirement, ensure to also have enough retroversion power after recycling again to ensure Contact good F-type connector.

Utility model content

In view of problem above, the utility model provides one kind and had both met frequency range performance requirement, ensures recycling again There is enough retroversion power to ensure to contact good F-type connector afterwards.

In order to realize above-mentioned purpose of utility model, the utility model provides following technical scheme：A kind of F in the utility model Type connector, including housing, first medium, second medium, center PIN needle, water proof rubber circle, step, pressure ring, waterproof gasket, PIN needle is slotted and circle riveting, and the housing is cylindrical, and the housing is located at outermost, surrounds internals, the center PIN Pin is located at the center of housing, and the right side top of the center PIN needle is slotted provided with PIN needle, and the PIN needle is recessed at center PIN The both sides of pin respectively set one, also have two shell foots in the center PIN needle, and two shell foots, can when under tension Deform, due to the presence of PIN needle fluting, the right end of center PIN needle is in two semicircle shapes, during by tension force effect, institute The semicircle shape end for stating center PIN needle can be with two shell foots while deforming opening, and the first medium and second medium distinguish position In center PIN needle both ends, the step is located at the left side of second medium.

The first medium is located at the left side of center PIN needle.

The second medium is located at the right side of center PIN needle.

The first medium and second medium are dielectric.

The waterproof gasket is on the right side of first medium.

The pressure ring is on the right side of waterproof gasket.

The circle riveting is located at the outermost of housing.

Water proof rubber circle is additionally provided with below the center PIN needle, the invasion of water can be prevented to a certain extent.

The advantages of the utility model and beneficial effect are：One kind is provided and had both met frequency range performance requirement, ensures following again There is enough retroversion power to ensure to contact good F-type connector after ring use.The circular PIN needle of the standard F-connector, it is public After female is to inserting, two semicircles after two shell foots and PIN flutings deform simultaneously.So Φ 0.635, Φ 0.850, Φ 1.136 The docking of probe circular insertion after, still keep contact good.
