Abstract
The invention provides an aluminum alloy smooth rod cable radio frequency coaxial connector which comprises an inner conductor, an injection insulator and a pressing sleeve. The inner conductor is arranged in a center of an inner cavity of an outer conductor. An outer ring small head of the inner conductor is provided with the injection insulator, and a right end large head is provided with the pressing sleeve. A right end surface of the outer conductor is provided with a rear screw sleeve, and is provided with a sealing ring at a surface connection part. An inner ring of the rear screw sleeve is provided with a left turning pipe thread with coning and is provided with a sealing ring in a right end groove. The aluminum alloy smooth rod cable radio frequency coaxial connector can satisfy an assembly requirement of a 7/8'' aluminum cable, and completely can satisfy a '50 ohm radio frequency coaxial connection for mobile communication' standard technical requirement through testing and actual use. A problem of early failure caused by that an original coaxial connector can not be matched with the aluminum cable is solved. According to the invention, the left turning pipe thread with coning is used in the rear screw sleeve and a cable sheath for connection, sealing and waterproof problems are solved, and functions of connection and positioning in cable installation can be played.
Description
Technical field:
The present invention relates to the mobile communication base station main feeder cable with 7/8 " type aluminium alloy smooth shaft cable radio frequency (RF) coaxial connector.
Background technology:
The radio frequency (RF) coaxial connector that emission main feeder cable in mobile communication base station mainly at present uses 7/8 " type copper corrugated pipe radio frequency coaxial-cable, and being connected between main feeder cable and wire jumper antenna is to adopt 7/8 "; Because the copper cable cost improves constantly; Cable factory has released the coaxial cable that smooth aluminum pipe replaces bellows at present, and this kind cable not only loss is low, and the light cost of weight is than former copper cable low 1/3; And electrical performance indexes can be superior to the bellows cable, brings bigger material benefit for mobile operator and client.Because smooth aluminum pipe radio frequency coaxial-cable structure is different with former bellows radio frequency coaxial-cable structure, bring the structure and the electrical property that are attached thereto the radio frequency (RF) coaxial connector that connects to design again, could guarantee that its radiofrequency signal can mate low-loss transmission fully.Native copper 7/8 " the bellows copper cable is because outer conductor adopts big bellows structure; when connector and cable outer conductor are installed since bellows play position-limiting action make can not produce between connector and cable mobile; and the present invention is that smooth shaft can't directly be connected with former connector because of aluminium alloy cable outer conductor, so need to adopt special clamping mode.
Summary of the invention:
The object of the invention will provide a kind of aluminium alloy smooth shaft cable radio frequency (RF) coaxial connector exactly, and it can solve present cable factory and adopt smooth aluminum pipe to replace the coaxial cable of bellows, can not with the problem of former radio frequency (RF) coaxial connector coupling.The objective of the invention is to realize like this; Aluminium alloy smooth shaft cable radio frequency (RF) coaxial connector; Comprise that inner wire, injection moulding insulator, gland form; It is characterized in that: the inner chamber central authorities of outer conductor are provided with inner wire, and inner wire outer ring microcephaly is provided with the injection moulding insulator, and the right-hand member major part is provided with gland; The right-hand member surface of described outer conductor is provided with rear thread sleeve, and is provided with sealing ring in surperficial junction; Described rear thread sleeve inner ring is provided with the left-handed gas thread that has tapering, and in the right-hand member groove, is provided with sealing ring.The present invention can satisfy 7/8, and " matching requirements of aluminium cable all can be satisfied " tracking exchage 50 Europe RF coaxials are connected " standard technique requirement through test with actual using.Having solved former coaxial connector and aluminium cable can not mate, and the problem of the early failure that causes has satisfied the requirement of the electrical performance indexes of base station construction process main feeder cable connector.Solved water-tight problem between aluminium alloy cable and connector simultaneously; Former bellows cable is owing to there is big bellows structure in bellows, can add sealing ring; And existing aluminium alloy light smooth shaft cable outer conductor structure can't adopt sealing ring; So adopt the left-handed gas thread that has tapering to be connected in rear thread sleeve of the present invention and the cable cover(ing), not only can solve the water-tight problem, can also play the positioning action when connecting with the cable installation.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a partial enlarged drawing among Fig. 1 of the present invention;
1. inner wire, 2. injection moulding insulator, 3. gland, 4. outer conductor, 5. sealing ring, 6. rear thread sleeve, 7. sealing ring.
Embodiment: the present invention is described further below in conjunction with accompanying drawing;
Aluminium alloy smooth shaft cable radio frequency (RF) coaxial connector; Comprise inner wire 1, injection moulding insulator 2,3 compositions of gland; It is characterized in that: the inner chamber central authorities of outer conductor 4 are provided with inner wire 1, and inner wire 1 outer ring microcephaly is provided with injection moulding insulator 2, and the right-hand member major part is provided with gland 3; The right-hand member surface of described outer conductor 4 is provided with rear thread sleeve 6, and is provided with sealing ring 5 in surperficial junction; Described rear thread sleeve 6 inner ring being provided with have the left-handed gas thread of tapering, and in the right-hand member groove, are provided with sealing ring 7.During practical implementation, as shown in Figure 2, outer conductor and connector device timing rely on this structure and smooth shaft aluminium alloy outer conductor cable to compress through the band arcuate structure, guarantee that connector closely contacts with cable and guarantee to reach＞pulling force of 720N.The rear thread sleeve inner ring has adopted the left-handed gas thread that has tapering; Angle of thread control rationally; When being connected with cable jacket, guarantees rear thread sleeve that the two closely connects; Guarantee location and water-tight performance when connector and cable are installed, reached the requirement of mechanical performance tensile strength simultaneously, guarantee to construct easily in the assembling process and have stronger endurance square.Adopt novel clamping device, make between outer conductor rear end and cable to produce pressure and make cable aluminium alloy outer conductor distortion and produce one section cambered surface, the guide effect when having guaranteed assembling.In the design of connector inner wire; In order to guarantee the requirement that cooperates of inner wire and cable in the radio frequency (RF) coaxial connector assembling process; And frictional resistance is as far as possible little in the assurance assembling process; This structural design adopts phosphor-copper fluting bottling technique to handle, and can guarantee excellent contact property and intermodulation requirement simultaneously again.Thereby the mechanical performance and the electric property of mobile base station radio frequency main feed system have been guaranteed.
