Detailed description of the invention
The technical solution of the utility model is described in detail, in order to become apparent from, understand invention essence of the present utility model intuitively below with reference to drawings and the specific embodiments.
The present embodiment provides the tail structure 100 of a kind of cable connector, and this structure is mainly used in connecting and fixing cable 200, and owing to the structural design of the present embodiment is only at the afterbody of cable connector, therefore, other positions of cable connector no longer illustrate.
With reference to shown in Fig. 1 ~ Fig. 4, the tail structure 100 of the cable connector of the present embodiment includes the metal shell 10 of thin wall cylinder-shaped, inwall at metal shell 10 is provided with one layer of dielectric substrate 20, and dielectric substrate 20 right-hand member is (for ease of describing, the present embodiment sets the direction shown in figure as reference direction) form the connecting portion 30 of an annular, this three part of metal shell 10, dielectric substrate 20 and connecting portion 30 adopts integrated formed structure design, make between this three part-structure nested against one another, effectively to strengthen the structural strength of the tail structure 100 of adapter.In order to avoid between metal shell 10 and dielectric substrate 20, stress departs from, it is possible to the inwall of metal shell 10 is designed as out-of-flatness structure, and adopt the technique such as plastic by dielectric substrate 20 and connecting portion 30 machine-shaping.
Referring again to shown in Fig. 3 and Fig. 4, in order to make cable connector possess function of shielding, the present embodiment radially extends the claw 40 of a metal material at the inwall of dielectric substrate 20, with the screen layer of clamping cable 200 and be electrically connected with screen layer, simultaneously, also formed between claw 40 with metal shell 10 and electrically connect, so that metal shell 10 possesses electro-magnetic screen function.
In addition, the tail structure 100 of the present embodiment also includes the corrugated tube 50 being arranged on connecting portion 30 right-hand member, the internal diameter of this corrugated tube 50 is identical with the internal diameter of connecting portion 30, and all with cable 200(containing outside insulating barrier) external diameter suitable, in order to fixing cable 200.Corrugated tube 50 plays the effect of protection cable 200.Attractive in appearance for cable connector, the external diameter of the external diameter of corrugated tube 50 and connecting portion 30 is also configured as essentially identical.
The outer surface of above-mentioned connecting portion 30 is provided with the groove 31 of a ring shape, the outer surface of corrugated tube 50 is provided with wave groove 51, connecting portion 30 is connected with corrugated tube 50 with the heat-shrinkable T bush 60 outside corrugated tube 50 by being set in connecting portion 30, after heat-shrinkable T bush 60 heat shrinkable, its one end embeds in above-mentioned groove 31, the other end embeds in above-mentioned wave groove 51, thus realizing the connection of connecting portion 30 and corrugated tube 50.This connected mode not only good looking appearance, and reliably not easily get loose.
Additionally, the present embodiment is additionally provided with a water proof ring 70 at the inwall of connecting portion 30, this water proof ring 70 can form interference fit with the insulated outer surface of cable 200, thus preventing water and dust from entering inside adapter.
In sum, compared to existing plastic cement adapter, this utility model sets up metal shell in the outside of dielectric substrate, and metal shell and dielectric substrate adopt integrated formed structure design, thus enhancing the structural strength of cable connector.Compared to existing metal connector, this utility model design dielectric substrate, and the claw of metal material is set at the inwall of dielectric substrate, so that electrically connecting with the screen layer of cable, so that this utility model possesses function of shielding, and also can stop have that housing is charged and the potential safety hazard that produces at the complex condition of the slippage of cable.And, the connected mode not only structure of connecting portion and corrugated tube reliably not easily gets loose, and good looking appearance.
The foregoing is only preferred embodiment of the present utility model; not thereby its scope of the claims is limited; every equivalent structure transformation utilizing this utility model description and accompanying drawing content to make; directly or indirectly it is used in other relevant technical fields, all in like manner includes in scope of patent protection of the present utility model.
