Abstract
The utility model discloses a DIN type 1/2' ultra-soft radio-frequency coaxial cable connector with the advantages of stable quality and high versatility, which mainly comprises an outer conductor of the connector, an insulated supporter, an inner conductor of a contact pin, and a cable fixing sleeve. The utility model is characterized in that the cable fixing sleeve is designed in the mode of arc-shaped internal threads, a fastening threaded sleeve is added in the cable fixing sleeve, and an H waist drum spring one section of which is an elastic contact is arranged in the inner conductor of a contact pin. The utility model has the advantages that the cable fixing sleeve is designed in the mode of arc-shaped internal threads, so the disadvantages of trapezoidal internal threads are overcome; the connector has high versatility; the inner conductor of a contact pin is provided with the H waist drum spring and an axial dead slot, so the nonlinear contact is lightened or eliminated; the fastening threaded sleeve is arranged in the cable fixing sleeve, so radio-frequency coaxial cables are not easy to loose; the thickness of the tube wall of the cable fixing sleeve is decreased and the cost is saved. The connector can be widely applied to the connection between feeder wires and jumping wires in mobile communication base stations, and the connection between jumping wires and equipment.
Description
Technical field
The utility model relates to being connected of in mobile communication base station wire jumper and feeder line, a kind of super gentle radio frequency coaxial-cable connector that is connected extensive use between wire jumper and the equipment, the architecture advances of the super gentle radio frequency coaxial-cable connector of in particular a kind of DIN type 1/2 ＂.
Technical background
There is following defective in the super gentle radio frequency coaxial-cable connector of DIN type 1/2 ＂ of Cai Yonging in the market:
1. be the helix tube shape owing to cable outer conductor, yet the key elements such as helix tube crest diameter, trough diameter and pitch of each manufacturer production manufacturing all have bigger difference.Cause the same size internal thread of cable fixed cover can not wildcard in all producer's cables, often need with corresponding producer cable work with addition of the worker, the interchangeability of its connector is poor;
2. because there is burr in the cable inner conductor end face, when cable and connector were installed, the workmen need make chamfered to the cable inner conductor end face, otherwise owing to the influence of burr causes the severe nonlinear contact, influenced the electric property of cable-assembly;
3. the resistance to tension deficiency (being generally 300N) of structure clamping device in addition, radially connects also insecure: between joint and the cable relative vibration takes place easily when being vibrated, cause the irregular variation of electric property.
The utility model content
At the above-mentioned technological deficiency that had existed already, the utility model proposes the super gentle radio frequency coaxial-cable connector of DIN type 1/2 ＂ of a kind of steady quality, highly versatile.
The technical solution of the utility model is achieved in that the super gentle radio frequency coaxial-cable connector of a kind of DIN type 1/2 ＂, mainly form by connector outer conductor, insulation supporter, contact pin inner wire, cable fixed cover, its difference is, the cable fixed cover is designed to the arc internal thread, in the cable fixed cover, set up fastening swivel nut, the contact pin inner wire is designed to the brass material boring and becomes composite holes, and a bit of H waist drum spring of packing in the contact pin inner wire describedly has axial dead slot on H waist drum spring.
Described H waist drum spring is resilient contact, designed pitch length simultaneously and be former three pitch length 0.86～1.2 times.
Effect of the present utility model can demonstrate fully out from table 1, table 2, the listed data of table 3, and concrete advantage is as follows:
1. the cable fixed cover is designed to the arc internal thread and changes the shortcoming that has overcome trapezoidal internal thread, simultaneously pitch length is designed to 0.86～1.2 times of former three pitch length; Because pitch of design less than of pitch length, promptly female surface with regard to having prevented that effectively the difference owing to each parameter of cable outer conductor from can not screw in the problem of cable holder, therefore has highly versatile like this less than a whole circle.
2. the contact pin inner wire is improved: former be designed to behind the elastomeric material bore hole becomes springhole in axially grooved closing in after the closing in; When the axle that has a burr when the cable inner conductor end face inserts, its burr is sandwiched between hole/axle probably, and this has damaged not only that contact has also caused the not cylindricity of contact pin inner wire outer surface and the electric property that influences connector.The brass material boring that is designed to after the improvement becomes composite holes, the a bit of resilient contact of packing into, because resilient contact is swelling-waist shape and has axial dead slot, when cable inner conductor inserts, front end has burr to be got out of the way by " drum ", and the cylinder of cable inner conductor is held tightly by " waist " normal pressure of resilient contact.The design of this novelty alleviates or has eliminated nonlinear contact, has protected the cylindricity of contact pin inner wire outer surface constant simultaneously; And contact pin inner wire total length has lacked 50% than original structure.
3. set up fastening swivel nut in the cable fixed cover, it is loosening that radio frequency coaxial-cable is difficult in the cable fixed cover, also can reach the thickness that reduces cable fixed cover tube wall simultaneously, saves cost; And cable outer conductor improved, and its length has lacked 50% than original structure; The connector total length has shortened 20% than original structure on the basis that structure is strengthened.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 cuts open figure for the office of an embodiment of the utility model;
Fig. 2 is the location drawing of cable inner conductor described in Fig. 1;
Fig. 3 is the structure chart of the spring of H waist drum described in Fig. 1 and Fig. 2.
Among the figure: 1, connector outer conductor; 2, insulation supporter; 3, contact pin inner wire; 4, H waist drum spring; 5, axial dead slot; 6, cable fixed cover; 7, arc internal thread; 8, fastening swivel nut; 9, cable outer conductor; 10, cable inner conductor; 11, cable inner conductor end face; 12, pitch.
Embodiment
Embodiment one:
From Fig. 1, Fig. 2, among Fig. 3 as can be seen, the super gentle radio frequency coaxial-cable connector of a kind of DIN type 1/2 ＂, mainly by connector outer conductor 1, insulation supporter 2, contact pin inner wire 3, cable fixed cover 6 is formed, wrap insulate supporting 2 between contact pin inner wire 3 and the connector outer conductor 1, contact pin inner wire 3 is designed to the brass material boring and becomes composite holes, the a bit of H waist drum spring 4 of packing into, H waist drum spring 4 is a resilient contact, and on H waist drum spring 4, have an axial dead slot 5, cable fixed cover 6 is designed to arc internal thread 7, set up fastening swivel nut 8 in cable fixed cover 6, pitch 12 length are 0.86～1.2 times of former three pitch length.
During installation, at first to the cable outer layer wire stripping, then cable outer conductor 9 is screwed in cable fixed cover 6, at this moment cable outer conductor 9 end faces can exceed the about 2～3mm of cable fixed cover 6 end faces, cable outer conductor 9 is screwed in and tightens with spanner, therefore, to contact with cable outer conductor 9 be to coincide very much and reliably to connector outer conductor 1.Owing to resilient contact is H waist drum spring 4 and has axial dead slot 5, when cable inner conductor 10 inserted, cable inner conductor end face 11 jagged quilts " drum " got out of the way, and the cylinder of cable inner conductor is held tightly by " waist " normal pressure of resilient contact.
