Abstract
The invention discloses a method for connecting a cable shielding layer with a metal terminal shell, which belongs to the technical field of digital communication. The method for connecting the cable shielding layer with the metal terminal shell is used for connecting the cable shielding layer with the metal terminal shell and is characterized in that: a continuous conducting shielding layer which wraps a conductor is arranged in a cable sheath; and the wrapped conductor is connected with the metal terminal shell. The method of the invention increases the reliability of the connection between the cable shielding layer and the metal terminal shell, improves the shielding effect of communication cables, reduces contact resistance and signal disclosure, is in favor of signal transmission and the like and can be widely applied to digital communication cable industry.
Description
Technical field
The invention belongs to the digital communication technology field, particularly relate to a kind of cable shield and metal terminal shell method of attachment.
Background technology
At present, develop rapidly along with digitized, the communication cable assembly is towards high frequency small, and low decay is anti-interference good, and the signal direction such as little that leaks develops.Because some small-sized terminals do not design the special-purpose union piece of cable shield and terminal metal shell, therefore can not change along with the external diameter of cable and adjust.The external diameter of well known cable is not the circle of standard, sometimes there are phenomenons such as thickness is uneven even overproof, had a strong impact on the contact reliability of cable shield and terminal metal shell, caused the shielding contact resistance to rise violently in the time of indivedual, shield effectiveness technical problem such as fall sharply.
Summary of the invention
The present invention provides a kind of cable shield and metal terminal shell method of attachment for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide a kind of reliability that connects between cable shield and the terminal shell that increases, improve the shield effectiveness of communication cable, reduce contact resistance, reduce signal and leak, help the cable shield and the metal terminal shell method of attachment of characteristics such as signal transmission.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of cable shield and metal terminal shell method of attachment link together cable shield and metal terminal shell, are characterized in: continuous conductive shielding layer is arranged in the cable cover(ing), and the conductive shielding layer coiled conductor, coiled conductor connects metal terminal shell.
The present invention can also adopt following technical scheme:
Described cable shield and metal terminal shell method of attachment are characterized in: coiled conductor connects metal terminal shell and adopts welding or crimping connected mode.
Described cable shield and metal terminal shell method of attachment are characterized in: coiled conductor is a copper wire lay configuration conductor.
Advantage and good effect that the present invention has are:
Cable shield and metal terminal shell method of attachment be owing to adopted brand-new technology scheme of the present invention, and compared with prior art, the present invention has and adopted conductor material solderless wrapped connection cable shield, then this conductor is connected to method on the terminal shell.The present invention has increased the reliability that connects between cable shield and the terminal shell, has improved the shield effectiveness of communication cable, has reduced contact resistance, has reduced signal and has leaked, and helps signal transmission etc., can be widely used in the digital communication cable industry.
Description of drawings
Fig. 1 is cable shield of the present invention and metal terminal shell syndeton schematic diagram.
Among the figure, 1, core; 2, screen; 3, conductor; 4, cable cover(ing).
Embodiment
For further understanding technology contents of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of cable shield and metal terminal shell method of attachment, cable shield and metal terminal shell are linked together, be characterized in: continuous conductive shielding layer is arranged in the cable cover(ing), and conductive shielding layer twines copper wire lay configuration conductor, and coiled conductor connects metal terminal shell.Coiled conductor connects metal terminal shell and adopts welding or crimping connected mode.
Implementation process: cable cover(ing) 4 is peeled off exposed the woven shield 2 and the core 1 that will twine earlier; Then, on braid, twine copper wire stranded conductor 3; At last, conductor is welded or is crimped onto on the terminal shell.
Present embodiment is connected to this conductor on the terminal shell then by solderless wrapped connection conductor material in the shielding of cable, thereby improves the connectivity of cable and termination contact.The cable terminal assembly of common connection with compare by the cable terminal assembly of this kind method operation: reliability obviously improves, and the shielding properties of assembly is obviously improved, and contact resistance reduces more than 50%, and signal leaks and reduces more than 10%.
Claims (3)
1. cable shield and metal terminal shell method of attachment, cable shield and metal terminal shell are linked together, it is characterized in that: continuous conductive shielding layer is arranged in the cable cover(ing), the conductive shielding layer coiled conductor, coiled conductor connects metal terminal shell.
