Description

Coaxial cable connector

Technical field

The utility model relates to a kind of cable connecting arrangements, belong to cable connector technical field.

Background technique

The coaxial cable connector of the prior art is mainly made of active joint, intermediate connection tube and outer tube, and centre connects Adapter tube is first to be equipped with a boss, and middle part is undergauge section, and tail end is conical head, conical head end cap of the active joint from intermediate connection tube On intermediate connection tube, outer tube crosses win engagement sleeves on intermediate connection tube close to active joint position, and outer tube tail end is in Between there are annular gaps between connecting tube；The coaxial cable connector in use, by the oversheath of coaxial cable, shielded layer and absolutely Edge layer clips a part in succession, exposes cored wire conductor, so that the end of coaxial cable is stepped from inside to outside distribution, core wire is led Body is axially inserted into intermediate connection tube together with insulating layer from taper head end, and cored wire conductor can be stretched out out of active joint, screen It covers layer and oversheath covers outside intermediate connection tube, and can fill out the annular gap between outer tube and intermediate connection tube substantially It is full, at this point, making its local deformation with specific purpose tool radial compression outer tube, insulating layer and shielded layer are pressed on intermediate connection Pipe is outer, that is, completes the connection of the coaxial cable connector and coaxial cable, hereafter, can be by active joint by the coaxial electrical Cable is connected with the radio-frequency terminals of other coaxial cables or electrical equipment.The coaxial cable connector have the advantages that it is easy to connect, But the deficiency for also having its intrinsic：Essentially consisting in deforms outer tube by squeezing, the ring between outer tube and intermediate connection tube Shape gap becomes unevenly, it cannot be guaranteed that one week of shielded layer can be good with intermediate connection tube contact, leads to shield bad, letter Number loss is big, transmit it is unstable, vulnerable to interference.

Utility model content

The purpose of the utility model is to provide the coaxial cable connectors that one kind can overcome drawbacks described above, so that intermediate connection Guan Nengyu shielded layer more preferably contacts, and signal transmitting is more stable, meanwhile, have both convenient advantage of constructing.

What the purpose of this utility model was realized in：A kind of coaxial cable connector, including active joint, guide pin group Part, intermediate connection tube, outer tube and tail pipe, guide pin component include the outer seat of guide pin, guide pin inner seat and guide pin, the end of the outer seat of guide pin Equipped with positive stop lug boss, the outer seat of guide pin, which sequentially passes through active joint and housing tube end and formed with outer tube, to be interference fitted, guide pin Inner seat seat tail portion outside guide pin is inserted into outside guide pin in seat, and the tail portion of guide pin expands and is located in guide pin inner seat, and the end of guide pin is worn It crosses guide pin inner seat and the outer seat of guide pin is stretched out from active joint, the tail portion of guide pin has for accommodating inserting for coaxial cable core wire conductor Mouthful, intermediate connection tube is socketed in outer tube, and intermediate connection tube end and outer tube form and be interference fitted and have ladder-like limit Bit architecture, intermediate connection tube tail portion are equipped with conical head, there are annular gap between intermediate connection tube tail portion and outer tube, in guide pin The tail portion of seat is protruded into intermediate connection tube end, and tail pipe cooperates insertion outer tube from outer tube tail portion, and tail pipe end includes outside one Cyclic structure and an inner annular structure, outer ring-like structure and inner annular structure pass through several micro- companies of uniformly distributed interconnecting piece in its tail portion It connects, outer ring-like structure is socketed in outside outer tube, and inner annular structure is socketed in inside outer tube, and tail pipe middle part can be protruded into outer for one The undergauge section of inside pipe casing, tail pipe tail portion are equipped with limited step corresponding with outer tube tail end.

The device makes its distribution that is stepped from inside to outside in use, coaxial cable end head annular is cut, by it from tail Pipe tail portion is axially inserted into, and cored wire conductor is inserted into intermediate connection tube together with insulating layer, and cored wire conductor protrudes into socket, shielding Layer and oversheath cover in the annular gap outside intermediate connection tube, at this point, compressing axially tail pipe with tool, cause interconnecting piece disconnected It opens, outer ring-like structure is socketed in outer tube tail portion completely, and inner annular structure continues inwardly to move under responsive to axial force, persistently squeeze Coaxial cable is pressed, shielded layer and oversheath are deformed and mutually compress with intermediate connection tube, and cored wire conductor end connects with guide pin Touching.At this point, limited step and sealing ring are contradicted just in outer tube tail portion.Axial force is shed, tail pipe can be kept to oversheath Jam-packed state, the technical solution make tail pipe from circumferencial direction jam-packed oversheath, and shielded layer can well be contacted with intermediate connection tube, The bad bring a series of problems of shielding is avoided, keeps signal transmitting more stable, loss is small, meanwhile, the utility model connection It is firm, it is not easy to loosen.The device can be reliably used for being connected and fixed for coaxial cable.

In order to guarantee that guide pin position in guide pin inner seat is able to maintain fixation, the tail portion outer wall of guide pin is equipped with boss, leads The position that needle inner seat corresponds to boss is equipped with the groove matched with boss.

For the ease of coaxial cable insertion, the tail portion opening of socket, guide pin inner seat and/or tail pipe is in horn-like.

In order to which when coaxial cable is inserted into, shielded layer and oversheath are more successfully socketed in the ring outside intermediate connection tube In shape gap, the open-ended of tail pipe is in horn-like.

To be further ensured that sealing, internal oxidation is avoided, position and/or the limit of positive stop lug boss two sides are corresponded in active joint Position stepped ends position is equipped with sealing ring.
