Abstract
The invention belongs to microwave communication devices, and relates to a structure of a radio frequency coaxial connector, in particular to a connecting threaded sleeve mounting structure of the radio frequency coaxial connector. In the connecting threaded sleeve mounting structure, at least one end of an outer conductor is sleeved with a connecting threaded sleeve; the rear end of the inner wall of the connecting threaded sleeve is provided with an inward convex limiting step; the front section of the inner wall of the connecting threaded sleeve is provided with a section of connecting threaded section for connecting with an external coaxial device; a section of unthreaded hole section is arranged between the connecting threaded section and the limiting step; the end of the outer conductor is provided with a section of assembly part capable of being separated from a main body; the assembly part is connected with the end of the outer conductor through threaded fit; the outer wall ofthe assembly part is provided with an outward protuberant convex shoulder; the axial position of the convex shoulder is positioned in the unthreaded hole section of the connecting threaded sleeve andcan stop the limiting step from falling out of the end of the outer conductor; and the outer wall of the convex shoulder is provided with external threads capable of matching with the connecting threaded section of the connecting threaded sleeve. The connecting threaded sleeve mounting structure is simple in structure, convenient in mount and reliable in connection.
Description
Technical field
The invention belongs to microwave communication device, relate to the structure of radio frequency (RF) coaxial connector, specifically is a kind of connection threaded sleeve mounting structure of radio frequency (RF) coaxial connector.
Background technology
Common radio frequency (RF) coaxial connector generally partly is made up of outer conductor, inner wire, insulator etc., end conductor is with and is used for the connection swivel nut that is connected with other coaxial components outside, connect swivel nut should and outer conductor between keep certain axial limiting, can rotate freely again simultaneously.In traditional radio frequency (RF) coaxial connector, the installation that connects swivel nut generally is to connect swivel nut at afterbody inwall car system one cannelure, and also car one cannelure on the outer conductor outer wall connects two parts by the snap ring that is placed between two cannelures.The reliability that this structure is installed inconvenience, connection is lower.
Summary of the invention
Technical problem to be solved by this invention is, a kind of simple in structure, easy for installation, connection threaded sleeve mounting structure of connecting reliable radio frequency (RF) coaxial connector is provided.
The connection threaded sleeve mounting structure of radio frequency (RF) coaxial connector of the present invention includes the outer conductor that is mounted with inner wire and insulator in one section inner chamber, is with one at least one end of outer conductor and connects swivel nut; The rear inner wall of described connection swivel nut is provided with inwardly protruded limited step, and the inwall leading portion that connects swivel nut is provided with one section and is used for the connecting thread section that is connected with the outer, coaxial device, is one section unthreaded hole section between connecting thread section and the limited step; The end of described outer conductor have one section can with body portion from assembly, assembly is connected the end of outer conductor by threaded engagement, the outer wall of assembly is provided with the convex shoulder to outer process, and the axial location of this convex shoulder is positioned at the unthreaded hole section of above-mentioned connection swivel nut and can stops that limited step deviates from from the outer conductor end; Connect in the swivel nut inner chamber and be mounted with sealing ring.The outer wall of described convex shoulder is provided with the external screw thread that can match with the connecting thread section that is connected swivel nut.
The present invention is simple in structure, connects reliably, only need can finish assembling process by the several times threaded engagement, has made things convenient for installation.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
The accompanying drawing illustrated embodiment is a radio frequency (RF) coaxial connector that comprises outer conductor 1, inner wire 2 and insulator 3, end at outer conductor is with connection swivel nut 4, connect the swivel nut rear inner wall limited step 41 is set, be followed successively by one section unthreaded hole section 42 and one section connecting thread section 43 before the limited step, connect swivel nut and be connected with the outer, coaxial device by the connecting thread section.The end of outer conductor 1 is not an overall structure, but by the assembly 11 that is threaded, the outer wall of assembly is provided with the convex shoulder 12 to outer process, convex shoulder by axial limiting in connecting the unthreaded hole section 42 of swivel nut, because convex shoulder 12 stops mutually with the limited step 41 that is connected the swivel nut rear end, can stop limited step to be deviate from, and limited step form and is connected required axial impetus when connecting swivel nut and be connected with the outer, coaxial device with the contact portion of convex shoulder from the outer conductor end.Connect and be mounted with sealing ring being tightly connected in the swivel nut inner chamber in order to realization and other coaxial components.The outer wall of convex shoulder 12 is provided with external screw thread 13, and this external screw thread can match with the connecting thread section 43 that is connected swivel nut.
Assembling process of the present invention is: at assembly 11 with before the main body of outer conductor 1 is connected, to connect swivel nut 4 earlier is enclosed within on the outer conductor main body, spin assembly 11 and outer conductor fixing again, to connect swivel nut 4 outside end conductors then moves, by cooperating of external screw thread 13 on connecting thread section 43 and the convex shoulder, can revolve convex shoulder 12 with connecting swivel nut, and make convex shoulder enter into the unthreaded hole section 42 that connects swivel nut.
Claims (2)
1, a kind of connection threaded sleeve mounting structure of radio frequency (RF) coaxial connector, include the outer conductor 1 that is mounted with inner wire 2 and insulator 3 in one section inner chamber, at least one end at outer conductor 1 is with a connection swivel nut 4, it is characterized in that: the rear inner wall of described connection swivel nut 4 is provided with inwardly protruded limited step 41, the inwall leading portion that connects swivel nut is provided with one section and is used for the connecting thread section 43 that is connected with the outer, coaxial device, is one section unthreaded hole section 42 between connecting thread section and the limited step; The end of outer conductor 1 have one section can with the body portion of outer conductor from assembly 11, assembly is connected the end of outer conductor by threaded engagement, the outer wall of assembly is provided with the convex shoulder 12 to outer process, and the axial location of this convex shoulder is positioned at the unthreaded hole section 42 of above-mentioned connection swivel nut and can stops that limited step 41 deviates from from the outer conductor end; Connect in the swivel nut inner chamber and be mounted with sealing ring.
2, the connection threaded sleeve mounting structure of radio frequency (RF) coaxial connector according to claim 1 is characterized in that: the outer wall of described convex shoulder 12 is provided with the external screw thread that can match with the connecting thread section 43 that is connected swivel nut.
