Description
Technical field
The present invention relates to a kind of connector, particularly a kind of 7/16 negative connector.
Background technology
Radio frequency (RF) coaxial connector is one of maximum device of communication system applications, and its function is with system and system, equipment and equipment, and coaxial systems such as parts and parts couple together, and make the signal can undistorted undamped continuous conducting.Fast development along with telecommunications, kind and function for radio frequency (RF) coaxial connector constantly propose new requirement, require to use more convenient, structure is more suitable, cost is lower, and performance is more excellent etc., to adapt to the needs that telecommunications develop rapidly, the basic structure of coaxial connector is the inner wire by input signal, and the insulating medium layer of the outer conductor of output signal and isolation two conductors constitutes.Coaxial connector is paired use, and wherein inner wire is called positive connector for the aciculiform structure, and another kind of inner wire is that inner hole structure is called negative connector.Coaxial connector is a kind of dual-port device, and wherein an end is fixedlyed connected with connected piece, and the other end and matching connector flexibly connect, and uniting becomes one also can load and unload at any time so that linked.Negative have threaded connection to be connected two kinds with straight cutting with the outer conductor connected mode of positive connector, the reliability that is threaded height, shock resistance is strong, working band is wide, but loading and unloading need the time long, inefficiency, and this is unfavorable for device miniaturization to need bigger operating space, adopt of common large and medium-sized connector is threaded more, and wherein 7/16 is to belong to large-scale connector mainly all being threaded of engineering employing in the past.
7/16 negative connector is normal to can be described as 7/16 socket with the equipment use that is fixed together, the 7/16 socket outer conductor just diameter of bore of shell is 16 millimeters, outside diameter is 29 millimeters, wall thickness reaches 13 millimeters, wall thickness must heavily be unfavorable for using and transporting, the shell of wall thickness body weight all is designed to two-layer usually hereto, wherein internal layer is as the outer conductor of coaxial configuration, skin is to be used for the helicitic texture that is connected with positive connector, form a useless tubular space between the ectonexine, how double casing shapes with a block of material, the heel that is exactly two-layer shell is to connect together, under normal conditions when needs become fast inserting structure with 7/16 jack design, just should remove skin with screw thread, on the internal layer outer conductor, need carry out fast inserting structure design again by structure and size, but some communication engineerings propose a kind of have simultaneously be threaded and the fast 7/16 negative connector demand that is connected two kind workers energy of inserting, can be called duplex receptacle to this connector, the design duplex receptacle needs to be provided with fast inserting structure on the cylindrical of outer conductor, slotting soon type positive connector inserts from tubular space with the fast inserting structure of outer conductor and is connected; The external screw thread size M29 of duplex receptacle and the diameter of bore φ 16 of internal layer outer conductor must identically with 7/16 negative connector of single worker's helicitic texture can not change, so that with single worker's socket compatible exchange, because the restriction of these two sizes, make the design that realizes satisfied duplex requirement very difficult, will be between double shells insert fast 7/16 a positive connector radial dimension of inserting type in the tubular space and seem very not enough, this just requires the structure that the fast inserting structure size of outer conductor must be corresponding with the positive connector of pairing and the pairing design of size strictness.
