Abstract
The invention relates to a dual-thread seal high-strength F type coaxial cable connector which is used for connecting a coaxial cable to an equipment interface. The coaxial cable connector comprises a connecting nut, a connector body and an elastic connecting body, wherein the connector body is provided with rear-section threads and front-section taper threads; the rear-section threads are matched and connected with a cable insulator; the front-section taper threads are used for being spirally connected with a cable sheath layer which is hermetically matched and connected with a cable sheath; the rear-section threads are used for being spirally connected with the cable insulator, so that the cable insulator is hermetically matched and connected with the connector body; a rear inner taper section and a front inner taper section are arranged between the rear-section threads and the front-section taper threads; the rear inner taper section is used for accommodating the outer conductor of the cable and closely connecting the outer conductor with the connector body so as to form good electric contact; and the front inner taper section is used for accommodating the cable sheath layer screwed in by the front-section taper threads, so that the cable sheath is closely connected with the body and hermetically matched and connected with the cable sheath. The coaxial cable connector has the advantages of compact structure, convenient insertion, simple operation, stable mechanical performance and electric performance, and the like and is very suitable for connection of wired cable.
Description
Technical field
The present invention relates to a kind of dual-thread seal high-strength F type coaxial cable connector, be used for the connection of coaxial cable to equipment interface.
Background technology
Chinese patent CN1200480 discloses a kind of coaxial cable connector, and its structure and catenation principle are as follows: comprise a nut, a tubular axis, a body and a pressing sleeve pipe; Guide end in the end of coaxial cable inserts the connector nut and when pushing away guide hole through body, tubular axis can separate the external protection and the conductive net layer of coaxial cable with insulating barrier, the barb of tubular axis is partly inserted between the two; When the pressing sleeve pipe advanced on tool groove body, it can carry out the pressing of two places to the skin and the conductive net layer of coaxial cable.1., owing to tubular axis will be poured into outer conductor layer between external sheath layer and the insulating barrier this structure has following shortcoming:, because mostly being braiding, coaxial outer conductor adds aluminium foil or copper foil structure, aluminium foil or Copper Foil are plastic-aluminum combined or copper is moulded complex form, and plastic film layers is close to insulating barrier, therefore tubular axis is easy to insert between plastic film and the insulation when assembling, thereby causes cable and connector loose contact; 2., the type connector is connected the power deficiency with coaxial cable.
Summary of the invention
The objective of the invention is to shortcoming, a kind of high-intensity F type of two helicitic texture high leakproofness coaxial cable connector that has is provided at above-mentioned existing coaxial cable connector existence.
The present invention, comprise attaching nut and connector body, attaching nut and connector body are rotationally connected by the nonrigid connector buckle, connector body is provided with back segment screw thread and leading portion taper thread, back segment screw thread and cable insulator are connected, the leading portion taper thread is used for spiral stube cable line restrictive coating, be sealed and matched with the cable sheath and be connected, the back segment screw thread is used for spiral stube cable line insulator, cable insulation is sealed and matched with connector body to be connected, between back segment screw thread and leading portion taper thread, be provided with back internal taper section and preceding internal taper section, back internal taper section is used to hold the cable outer conductor and makes it and closely is connected with connector body, forms excellent electric contact; Preceding internal taper section is used to hold the cable cover(ing) layer of being sent to by leading portion taper thread spiral, and cable cover(ing) is closely linked to each other with body, and being sealed and matched with the cable sheath is connected.
The present invention, the cone angle of described leading portion taper thread is 5-20 °; The cone angle of back internal taper section is 80-100 °; The cone angle of preceding internal taper section is 10-25 °.
The present invention has compact conformation, patches conveniently, and is simple to operate, and the mechanical electric steady performance is fit to the wire cable cable and connects usefulness very much.When the terminal insertion of coaxial cable sheath connector body leading portion screw thread lead segment, the coaxial cable insulation cable end screws in the connector body back segment screw thread immediately, continues to rotate to assigned address, and coaxial cable and connector are combined closely.Because two sections are threaded before and after adopting, can prevent effectively that moisture from entering the repetition practicality that cable shield also can be realized connector, saves cost greatly.
