Description
Technical field
The utility model relates to a kind of self adaptation F type female joint of easy switching.
Background technology
The female joint of F type is a kind of radio-frequency joint that connects between the equipment such as cable television appliances, wall box, TV, generally all when house decoration, defaults in the body of wall.But when the user used, not all F type female joint was all come into operation (promptly connecting corresponding male joint), and those female joints of not coming into operation bigger reflection loss will occur owing to there is not the corresponding matched load, influence signal transfer quality.For fear of the problems referred to above, traditional method is in the female joint of not coming into operation, to install an extra load, to realize impedance matching; Though this can improve signal; But can destroy the outward appearance of original female joint, influence the aesthetics in house, strengthen staff's installation workload simultaneously; But also the extra load accessory that increased has caused the cost rising.
Summary of the invention
The purpose of the utility model is the self adaptation F type female joint that proposes a kind of easy switching; Make female joint under the two states that comes into operation and do not come into operation, all can obtain matched load; Thereby ensure signal quality, improve aesthetics, the workload that reduces a staff.
The self adaptation F type female joint of the utility model comprises the main body that is provided with externally threaded metal material; Said main body is hollow tubular and both ends open; The afterbody of said main body is provided with the fixed part of insulation material; Main body is utilized fixed part to be equipped with one and is stretched to the nook closing member of body interior and the switching shell fragment of a metal material that stretches to body interior, and the front end of said switching shell fragment is bent to form the service portion of " V " shape; The leading section of said main body is a shoulder hole; Be movably installed with the switching part of an insulation material in the said main body; Said switching part is provided with through hole and connects male joint to be used for nook closing member; The front end of said switching part stretches out outside the shoulder hole of main body, is folded with spring between the tail end of switching part and the said fixed part, and the tail end of said switching part also is provided with and can stretches into the guide structure that switches between shell fragment and the nook closing member.
In use; At first with main body (being the signal ground end of female joint) and switch shell fragment and utilize a build-out resistor to be connected that (this build-out resistor preferably is located on the pcb board of the equipment that uses; As long as will switch shell fragment links to each other with build-out resistor on the PCB through lead); Like this when this female joint is not come into operation, the front end of main body pushed switching part to by the spring of body interior under the effect of self elastic force, the guide structure that makes switching part with switch shell fragment and separate; This " V " shape service portion that switches shell fragment will contact with nook closing member under the elastic force effect of switching shell fragment; Thereby make nook closing member link to each other through switching shell fragment and build-out resistor successively, guaranteed impedance matching, reduced the reflection loss of signal with main body; When this female joint was come into operation, male joint was when screwing, and the through hole that not only can make the nook closing member of male joint pass switching part contacts with the nook closing member of female joint; Also can the tail end of switching part to female joint be promoted; The guide structure of switching part can stretch to and switch between shell fragment and the nook closing member like this, thereby makes the disconnection that electrically contacts of switching shell fragment and nook closing member, so just changed signal flow to; Make signal flow no longer pass through set build-out resistor, guaranteed the normal transmission of signal to male joint.
Further, said main body links to each other through a resistance with the switching shell fragment, and said resistance is arranged at body interior.So just need not build-out resistor of extra again increase in the outside of female joint, the user can directly be applied to this female joint to have improved versatility on the traditional device.
Further, the guide structure of said switching part is the cylinder of internal diameter greater than the nook closing member external diameter, and said nook closing member stretches to cylinder interior.Cylinder not only can play the effect of guiding; Avoid nook closing member to deflect, also because the sphere of action of cylinder is its periphery, therefore which kind of angle no matter switches shell fragment is positioned at; Cylinder all can guarantee the disconnection that electrically contacts that will switch shell fragment and nook closing member to have improved reliability in moving process backward.
Further, said switching part forms by joining before and after first switching part and second switching part, and the inside of said first switching part and second switching part is provided with the cavity that can supply nook closing member to stretch into.Therefore in user mode, nook closing member can stretch in the cavity of switching part like this, and whole female joint need not longly, has saved the space, the convenient installation.
Further, the front portion of the through hole of said switching part is tubaeform mouthful, leads with convenient nook closing member to male joint.
Further, said switching shell fragment is that latten(-tin) takes all of and processes, and switches shell fragment and be provided with reinforcement, to guarantee to switch the elasticity of shell fragment.
The self adaptation F type female joint of the utility model is through being provided with the switching shell fragment that cooperates with male joint; Make female joint under the two states that comes into operation and do not come into operation, all can obtain matched load; Thereby ensure signal quality, improve aesthetics, the workload that reduces a staff.
