Abstract
The utility model relates to a radio-frequency coaxial device for the communication field, in particular to a front sealing coaxial connector, which comprises a casing, an insulator and an inner conductor, wherein the front section of the casing is an insert section, and the back section of the casing is connected with a cable turnbuckle through threads, a step is arranged on the inner wall of the cable turnbuckle, an intermediate ring is arranged between the step and the back end of the casing, the intermediate ring is placed in a ring groove in front of the step, and the outer ring of the intermediate ring is provided with outer threads, the intermediate ring can be screwed into the cable turnbuckle through matching the outer thread with the inner threads of the front section of the cable turnbuckle, and finally enters into the ring groove, and a ring spring is arranged between the front end of the intermediate ring and the back end of the casing, a ring-shaped sealing ring groove is formed between the back end of the intermediate ring and the step, and a sealing ring is arranged in the sealing ring groove. The front sealing coaxial connector has small axial dimension, firm connection and excellent sealing effect.
Description
Technical field
The utility model relates to a kind of radio-frequency (RF) coaxial device that is used for communication field, specifically is a kind of preposition sealing coaxial connector.
Background technology
Common radio frequency (RF) coaxial connector has generally comprised shell, insulator and inner wire, and shell and leading portion are inserting section, and the shell back segment is used for importing the cable swivel nut with attached cable by being threaded.In traditional structure, shell back segment and cable swivel nut partly need be settled wire clamp and sealing ring, so its axial length is longer, have increased product size and weight, and material cost is also higher.
Chinese patent application 200710025231.8 discloses and has a kind ofly replaced the radio frequency (RF) coaxial connector structure of original wire clamp with the annular elastomeric spring coil, because the less axial width of ring spring, thereby can shorten the axial dimension of cable swivel nut greatly, has also made things convenient for installation.But in this structure, cable swivel nut back segment still will have one section long cylindrical shell and be used for settling sealing ring between cable swivel nut and the cable outer conductor, thereby axial length is still longer, and cable needs the length of wire stripping also longer when installing, and has increased cost; In addition, in this structure, sealing ring only relies on fixing elastic force to realize sealing, and its sealing effectiveness is difficult for guaranteeing.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of axial dimension little, be connected firmly, the preposition sealing coaxial connector of good sealing effect.
Preposition sealing coaxial connector of the present utility model includes shell, insulator and inner wire, the leading portion of shell is an inserting section, the shell back segment is by the cable swivel nut that is threaded, cable swivel nut inwall is provided with a step, an adapter ring is arranged between the rear end of this step and shell, adapter ring is positioned in the annular groove in step the place ahead, the adapter ring outer ring is provided with external screw thread, adapter ring can screw in the cable swivel nut and finally enter into annular groove by the screw-internal thread fit of this external screw thread and cable swivel nut leading portion, be provided with ring spring between the front end of adapter ring and the outer casing back, constitute the seal groove of an annular between adapter ring rear end and the above-mentioned step, in seal groove, be mounted with sealing ring.
The housing rear end in described ring spring the place ahead is provided with the conical surface of rear side outward.
The utility model concentrates on the front end of cable swivel nut with ring spring and sealing ring, thereby can shorten the axial dimension of cable swivel nut by the structure of adapter ring, makes entire product compact more; In addition, can the axial compression sealing ring in the screw-in process of cable swivel nut, the sealing ring inner ring is inwardly expanded, thereby can improve the sealing between itself and the cable outer conductor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, this preposition sealing coaxial connector includes shell 1, insulator 2 and inner wire 3, the leading portion of shell is an inserting section, the shell back segment is connected by the internal thread of external screw thread with cable swivel nut 4 leading portions, cable swivel nut inwall is provided with a step 41, an adapter ring 5 is arranged between the rear end of this step and shell, adapter ring is by its annular groove 42 that screws into the cable swivel nut and finally enter into step the place ahead, be provided with ring spring 6 between the front end of adapter ring 5 and the outer casing back, constitute a seal groove 7 between adapter ring rear end and the step 41, in seal groove, be mounted with sealing ring 8.
Be provided with the conical surface 11 of rear side outward in housing 1 rear end in ring spring 6 the place aheads.When cable was pushed into, the conical surface 11 on the shell can make the end of cable outer conductor be scooped up by the insulating barrier from the centre, forms outside flange, so just can stop further that ring spring 6 takes off from cable outer conductor.
Claims (2)
1, a kind of preposition sealing coaxial connector, include shell (1), insulator (2) and inner wire (3), the leading portion of shell is an inserting section, the shell back segment is by the cable swivel nut (4) that is threaded, it is characterized in that: cable swivel nut inwall is provided with a step (41), between the rear end of this step and shell (1), an adapter ring (5) is arranged, adapter ring is positioned in the annular groove (42) in step the place ahead, the adapter ring outer ring is provided with external screw thread, adapter ring can screw in the cable swivel nut and finally enter into annular groove by the screw-internal thread fit of this external screw thread and cable swivel nut leading portion, be provided with ring spring (6) between the front end of adapter ring and the outer casing back, constitute the seal groove (7) of an annular between adapter ring rear end and the step (41), in seal groove, be mounted with sealing ring (8).
2, preposition sealing coaxial connector according to claim 1 is characterized in that: the housing rear end in ring spring (6) the place ahead is provided with the conical surface of rear side (11) outward.
