The technical solution of the utility model is: a kind ofly exempt from the coaxial fitting of instrument easy assembling type, comprise coupling nut, the metal inner core that coupling nut, front end are connected with coupling nut is passed in the rear end, be fixed in the outer metal sleeve of metal inner core and hold cap tightly with the metal that the metal sleeve rear end is connected and fixed, described metal sleeve rear portion is provided with internal thread, and described metal is held the cap front portion tightly and is provided with the external screw thread that is spirally connected with described internal thread.
Further, described metal is held the external diameter of the internal diameter of cap greater than described metal inner core tightly.When the internal thread that makes metal hold the external screw thread of cap and metal sleeve rear end tightly was spirally connected precession, metal was held cap tightly and the oversheath of coaxial cable can be clamped between the periphery of metal inner core and the inwall that metal is held cap tightly.
Further, described metal inner core rear portion is provided with external screw thread, and the rear end periphery of described metal inner core has tapering.Like this, coaxial cable can be installed in the metal inner core while rotating, make the screen of coaxial cable separate with the metal inner core rear end that foaming layer is had tapering, and being easy to inside precession under externally threaded effect further radially outward expands, make internal core wire and foaming layer be positioned at metal in-core week side, and screen and external sheath layer being wrapped on the metal inner core periphery wall tightly, expanding simultaneously also makes the oversheath of coaxial line be held tightly cap by metal tightly to hold tightly.
Further, described coupling nut rear inner wall by after be provided with sealing ring holding part and spacing prominent muscle forward successively, described metal inner core front end is provided with spacing prominent muscle and cooperates spacing flange, described metal sleeve is positioned at coupling nut rear side and front inner wall and metal inner core periphery and fixes, and described metal inner core is arranged with the sealing ring between sealing ring holding part and metal sleeve front end outward.Sealing ring makes the front portion have waterproof action.
The periphery that described metal is held the cap front portion tightly is provided with the sealing ring storage tank, is provided with in the described sealing ring storage tank radially at metal and holds sealing ring between cap and the metal sleeve tightly.The rear portion of cable joint also has waterproof action like this.
Further, described metal is held the cap periphery tightly and is provided with anti-skidding line, plays anti-skidding effect when metal is held cap tightly hand-held rotation of user.
The utility model advantage is:
1. the utility model metal is held cap tightly and is connected by internal and external threads with metal sleeve, the foaming layer of cable and screen easily separately radially outward expand automatically by the external screw thread in the metal inner core outside simultaneously, easy for installation, need not tool using and can realize firm connection between coaxial wire and the joint.
2. be equipped with sealing ring before and after the utility model, waterproof action is all arranged before and after the cable joint that connects.
