Abstract
The utility model relates to improvement of a copper pipe connector of a smooth inner conductor of a radio frequency coaxial cable for mobile communication, which is characterized in that each grid of an umbrella bone-shaped inserted head of a connector is distributed in a plane radiation mode; the tail of the connector is provided with a folded oblique folding surface. The original structure and the performance of the connector can be ensured, and the good electrical contact and the contact strength of cables (inner diameter slight deviation) of the same specification and different manufacturers can both be ensured. Thereby, the suitable matching character of the connector and an inner conductor of a cable copper pipe can be enhanced, and stable and reliable electric connection can be ensured. The utility model has big contact area, and the connection failure rate with cables can be reduced. The connection failure rate can be reduced to below 100 PPM.
Description
Technical field
Utility model is about the improvement to smooth copper inner wire radio frequency coaxial-cable connector, and it is big to relate in particular to a kind of contact area that plugs together, and contact is reliable, and can adapt to the copper pipe inner wire connector that the same specification internal diameter size changes.
Background technology
Inner conductor of radio frequency coaxial cable is connected with connector, inserts the copper pipe inwall by its female connector usually, makes both form electrical connection.The connector female connector is connected with the copper pipe inner wire, have screw to connect again and be connected two kinds of forms with plug and since screw be connected the operative skill that is subjected to the workmen in the work progress influence bigger, and also inconvenience extremely of installation, therefore be superseded trend, the substitute is and adopt the plug plug-in type to connect.Existing connector female connector has two kinds of structures usually again, and a kind of is cylinder grizzly bar (Fig. 1,2), and its structure is axially to be processed with some planes grizzly bar 1 at a cylinder side face.Yet Fig. 1, the grizzly bar of cylinder shown in 2 plug, grafting grizzly bar external diameter can not be expanded, only be applicable to frock control better, it is the copper pipe internal diameter size consistency control cable of same manufacturer production preferably, same specification radio frequency coaxial-cable for the production of different manufacturers, unavoidably there is the size fluctuation deviation in its copper pipe inner wire internal diameter, so this cylinder grizzly bar plug, just being difficult to has good electrically contacting after assurance is pegged graft with the copper pipe inner wire, thereby can cause connecting the electrical property instability, the index deviation occurs, so this structure connector versatility is poor, uses limitation bigger.So someone changes it into umbrella frame shape (taper) structure (Fig. 3,4), each grizzly bar 1 is side at the root bias and plays the tapered circumference arrangement.This structure plug grizzly bar is that line contacts with the copper pipe inwall, pressure force is little, the oblique grizzly bar of side direction still can not be guaranteed to be electrically connected reliably with caliber deviation copper pipe inner wire in actual the use, still can cause and caliber deviation copper pipe switching performance instability, and it is poor to connect reliable consistency; Next, this structure connector plug owing to need the grizzly bar side direction is turned up, therefore causes grizzly bar fracture and damage easily in forming process, cause fabrication yield to reduce.So improved place of the value of still having.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of grafting compatibility good, big with the copper pipe crimp force, can effectively guarantee same specification cable copper tube inner wire, be the smooth copper inner wire radio frequency coaxial-cable connector that good electrical is connected with connector.
The utility model purpose realizes, the main improvement is with connector umbrella frame shape (taper) plug grizzly bar, rise and change the plane into alternately by the rotation side, and grizzly bar afterbody bias become inclined broken surface, thereby after the plug grizzly bar is inserted, after each grizzly bar adapts to copper pipe internal diameter radial contraction, its afterbody inclined broken surface can form good face with the copper pipe inwall and contact, thereby that has improved connector plug and cable copper tube inner wire cooperates contact area and contact strength, under copper pipe internal diameter trace changes, still can obtain good, stable, be electrically connected reliably.Specifically, utility model smooth copper inner wire radio frequency coaxial-cable connector comprises the umbrella rib type female connector, it is characterized in that said each grizzly bar of umbrella rib type female connector is the plane radiation and distributes, and its afterbody is turned up inclined broken surface.
Each grizzly bar afterbody of the said plug of utility model is turned up inclined broken surface, and main effect is the minor variations that more helps adapting to the copper pipe internal diameter size, makes insertion deviation inner diameter copper tube can both keep good electrical contact and contact strength.Its inclined broken surface can be in the same way, also can be incorgruous, but wherein bias is better in the same way to adopt especially, helps simplifying production and processing and makes.Turn up the angle and be preferably 10-20 °, knuckle is crossed conference and is caused existing copper pipe contact area to reduce; The too small then action effect of knuckle is not obvious.Afterbody inclined broken surface length is preferably 1/3 to 1/2 of grizzly bar length.
Its interior attachment plug of utility model connector, its grizzly bar is the plane radiation and arranges, and original size is still held in the front portion, back afterbody is turned up inclined broken surface, this structure not only can guarantee connector original structure and performance, and can both guarantee good electric contact and contact strength to same specification different manufacturers cable (the little deviation of internal diameter), thereby improved the compatibility of connector and cable copper tube inner wire greatly, guarantee to stablize, reliably be electrically connected, and contact area is big, reduce the failure rate that is connected with cable greatly, the connection failure rate can be reduced to below the 100PPM.
Below in conjunction with an embodiment, further specify the utility model structure.

Embodiment
Embodiment: referring to Fig. 5,6, utility model smooth copper inner wire radio frequency coaxial-cable connector, its female connector is umbrella frame shape (taper), and each alternately grizzly bar 1 is the plane radiation and distributes, and its afterbody has to be turned up about 15 °, be about the inclined broken surface 2 that accounts for grizzly bar 65%.
