Description

The male joint of a kind of grafting F type

Technical field

The utility model relates to the F type male joint that signal connects, and specifically is the male joint of a kind of quick grafting F type.

Background technology

The F type male joint that signal connects is a kind of radio-frequency joint that connects between the equipment such as cable television appliances, wall box, TV, injection casing is adopted in traditional grafting F type male joint, because in injection moulding process, the injection molding material of HTHP causes the distortion of insulation in splice insulation body, the radio frequency cable, destroyed impedance matching structure, cause the reflection loss variation easily, the defective that signal of telecommunication quality descends.

Summary of the invention

The purpose of this utility model is to overcome in the prior art because the shortcoming of the reflection loss variation that the Shooting Technique of HTHP causes, the decline of signal of telecommunication quality, provide a kind of and have assembling simply, avoid the distortion of insulation in splice insulation body, the radio frequency cable, the quick grafting F type male joint that keeps good impedance match helps the reception of signal.

The utility model provides the male joint of a kind of grafting F type, comprise the pin stamen, insulator, plastic casing, adapter body, wherein pin stamen, insulator are installed in the adapter body, the pin stamen interts the insulator intermediate throughholes, the wire through-hole that links to each other with the pin stamen is arranged in the adapter body, key is that an end of adapter body is the guiding surface of chamfering, and be inserted in the plastic casing that has open lumen, and adapter body and plastic casing are by convex edge and groove activity clamping, and the other end of plastic casing has the connecting through hole that communicates with inner chamber.Assembling for convenience, described adapter body and plastic casing are the wedge shape convex edge clamping of being inserted in the inner chamber that the periphery of the adapter body of plastic casing has wedge-shaped impression and plastic casing by convex edge and groove activity clamping, also can be inserted in the periphery of adapter body of plastic casing and plastic casing inner chamber pass through the mutual snap-in of broached-tooth design, realize unidirectional assembling.In order to prevent the rotation of cable main body, the inner chamber cross section of plastic casing is polygon-shaped, and the joint of inner chamber and connecting through hole forms a ladder plane, and is fixed with the metal stationary pipes on the ladder plane, the fixedly connected cable of metal stationary pipes.The end face on adapter body tape guide inclined-plane has the connection bump of band wire through-hole, the connection bump periphery has anti-skidding sawtooth, connection bump is inserted in the metal stationary pipes simultaneously, the corresponding metal stationary pipes of adapter body end face position is provided with the circular orientation groove, fixing metal stationary pipes and the friction that increases cable and metal stationary pipes.

Characteristics such as the utility model is owing to adopt the fit of plastic casing and the unidirectional assembling of adapter body, and the maintenance good impedance match helps the reception of signal, and it is simple to have production technology simultaneously, and rate of finished products height, cost are low.
