Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cladding structure, and more
particularly to a serial bus cladding structure that can efficiently
prevent an electromagnetic interference.
2. Description of the Related Art
A conventional serial bus structure in accordance with the prior art shown
in FIG. 3 comprises a plurality of serial buses 10, two metallic covering
layers 20 respectively mounted on upper and lower end faces of the serial
buses 10, and a glue layer 30 mounted between the serial buses 10 and the
covering layers 20.
However, the glue layer 30 is melted at a higher temperature, so that the
glue layer 30 easily leaks outward, thereby decreasing the sealing effect,
so that the conventional serial bus structure is interrupted by an
electromagnetic interference. In addition, it is necessary to bond the
covering layers 20 on the serial buses 10, thereby increasing the working
time and costs of fabrication. Further, the covering layers 20 decrease
flexibility of the serial buses 10. Further, the covering layers 20 have
different thickness, thereby producing uneven impedance, so that the
conventional serial bus structure cannot prevent an electromagnetic
interference efficiently. Further, the glue layer 30 is made of
non-transparent material, so that the arrangement of the serial buses 10
is not visible from the covering layers 20, so that the pitch between the
serial buses 10 cannot be adjusted to be kept at a constant value, thereby
decreasing the transmission effect of the serial buses 10.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a cladding
structure that can prevent an electromagnetic interference efficiently.
Another objective of the present invention is to provide a cladding
structure that has a rigid and stable construction.
A further objective of the present invention is to provide a cladding
structure that has a steady signal transmission.
A further objective of the present invention is to provide a cladding
structure that has an insulating surface layer mounted on the protective
layer to prevent a short circuit and to increase the lifetime of the
cladding structure.
A further objective of the present invention is to provide a cladding
structure, wherein the covering layer is made transparent, so that
arrangement of the serial buses is visible from the covering layer to
facilitate adjustment of the serial buses, so that the pitch between the
serial buses is adjusted to be kept at a constant value to maintain a
steady signal transmission effect.
In accordance with the present invention, there is provided a cladding
structure, comprising a plurality of serial buses, an insulating covering
layer surrounding the serial buses, a metallic plating layer mounted on
the covering layer, and a metallic protective layer mounted on the plating
layer, wherein:
each of the serial buses includes a co-axial cable;

buses 1 includes a co-axial cable 12 to connect different circuit boards
and to transmit the signals of the circuit boards. Each of the serial
buses 1 includes FFC, FPC and FCC.
The covering layer 2 is preferably made of a heat-resistant material, such
as Mylar, PVC, PU or the like, surrounding an outer side of the serial
buses 1 to form an insulating layer to protect the serial buses 1. In
addition, the Mylar material is made transparent, so that the arrangement
of the serial buses 1 is visible from the covering layer 2 so as to
facilitate adjustment of the serial buses 1, so that the pitch between the
serial buses 1 is kept at a constant value to maintain a steady
transmission impedance.
The plating layer 3 is preferably made of a metallic material, such as a
copper or the like, that can prevent an electromagnetic interference (EMI)
efficiently. The plating layer 3 is attached on a surface of the covering
layer 2 in a sputter plating manner. In addition, the plating layer 3 has
a portion connected to the ground to conduct the charges of the
electromagnetic waves, so that the surface of the covering layer 2 forms
an EMI isolation efficiently.
The protective layer 4 is preferably made of a wear-resistant and
anti-oxidant metallic material, such as a stainless steel or the like. The
protective layer 4 is attached on a surface of the plating layer 3 in a
sputter plating manner to enhance the wear-resistant and anti-oxidant
strength of the surface of the plating layer 3.
The surface layer 6 is preferably made of an insulating material, such as a
rubber or the like, surrounding a surface of the protective layer 4
without detachment.
Accordingly, the cladding structure can prevent an electromagnetic
interference efficiently. In addition, the cladding structure has a steady
signal transmission. Further, the cladding structure has an insulating
surface layer 6 mounted on the protective layer 4 to prevent a short
circuit and so as to increase the lifetime of the cladding structure.
Further, the covering layer 2 is made transparent, so that arrangement of
the serial buses 1 is visible from the covering layer 2 to facilitate
adjustment of the serial buses 1, so that the pitch between the serial
buses 1 is adjusted to be kept at a constant value to maintain a steady
signal transmission effect.
Referring to FIG. 2, a serial bus cladding structure in accordance with
another embodiment of the present invention further comprises an isolation
layer 5 mounted between the protective layer 4 and the surface layer 6.
The isolation layer 5 is preferably made of an oxide material, such as an
indium and tin oxide (ITO) or the like, that can prevent an
electromagnetic interference (EMI) efficiently so as to enhance the signal
transmission effect.
Although the invention has been explained in relation to its preferred
embodiment(s) as mentioned above, it is to be understood that many other
possible modifications and variations can be made without departing from
the scope of the present invention. It is, therefore, contemplated that
the appended claim or claims will cover such modifications and variations
