Description

MICRO COAXIAL CABLE ASSEMBLY AND SLIDE MOBILE PHONE HAVING THE SAME
The present invention relates to a micro coaxial cable assembly, and more particularly to a micro coaxial cable assembly in which a body of a slide mobile phone is electrically connected to a display using a micro coaxial cable having a shielding function in itself. Also, the present invention relates to a slide mobile phone having such a micro coaxial cable assembly.
Generally, portable wireless terminals (hereinafter, referred to as "mobile phones") may be classified into bar-type phones, flip-type phones and folder-type phones based on their appearances. As designs of mobile phones are diversified recently, as disclosed in Korean Utility Model Registration No. 350760, Korean Utility Model Registration No. 355879, Korean Utility Model Registration No. 340081 and Korean Utility Model Registration No. 350698, a slide-type mobile phone in which a display is slid with respect to a body such that a keypad installed on a surface of the body may selectively open or close the display is newly put into the market and used widely.
Hereinafter, a structure of a conventional slide-type mobile phone is explained with reference to Figs. 1 to 3. Fig. 1 is a plane view showing a flexible printed circuit (FPC), Fig. 2 is a projected plane view showing a conventional slide-type mobile phone having the flexible printed circuit of Fig. 1, and Fig. 3 is a sectional view taken along the line A-A' of Fig. 2.
The conventional slide-type mobile phone includes a body 10, a display 20 slidably coupled to the body 10, and a flexible printed circuit assembly 30 for electrically connecting the body 10 to the display 20, as shown in Figs. 2 and 3.
The flexible printed circuit assembly 30 includes a flexible printed circuit (FPC) 32, and connectors 36, 34 coupled to both ends of the FPC and respectively coupled to an connection terminal 12 included in the body 10 and a connection terminal 22 included in the display 20, as shown in Fig. 1.
However, in the slide-type mobile phone, the FPC 32, the FPC 32 does not have a shielding function in itself, so a separate shielding member for shielding the FPC 32 should be installed. If such a shielding member is not installed, signals transferred through the FPC 32 may be distorted due to external electromagnetic waves, and in this case, the slide-type mobile phone may not be operated normally.
To solve such a problem, it may be conceived that t a plurality of micro coaxial cables (MCX) capable of giving a shielding function by themselves are mounted to a mobile phone as shown in Figs. 2 and 3 in stead of the FPC 32. However, in this case, the plurality of micro coaxial cables have very small radius of curvature, so the slide-type mobile phone may not satisfy a safety standard. This safety standard is satisfied only when the micro coaxial cables do not have any defect until the display 20 make 100,000 reciprocations.
The present invention is designed to solve the problems of the prior art, and therefore it is an object of the present invention to provide a micro coaxial cable assembly capable of giving a shielding function by itself without using any separate shielding member and also capable of being mounted to a slide-type mobile phone while satisfying safety standards.
Another object of the present invention is to provide a slide-type mobile phone having the above micro coaxial cable assembly.
In order to accomplish the above object, the present invention provides a micro coaxial cable assembly in which a plurality of micro coaxial cable units for electrically connecting a body and a display of a slide-type mobile phone are arranged in parallel, wherein each of the plurality of micro coaxial cable units includes a body-side fixing portion for fixture to the body; a display-side fixing portion for fixture to the display; and a curving portion located between the body-side fixing portion and the display-side fixing portion, wherein the curving portion is configured so as to form curves when the plurality of micro coaxial cable units are mounted to the slide-type mobile phone and such that an angle between a straight line connecting a rightmost point and a leftmost point of the curve and a bottom surface of the body is in a range greater than 0 degree but smaller than 90 degrees.
Preferably, the curving portions are configured to have radiuses of curvature increasing from any one of two micro coaxial cable units located at an outermost region to the other when the plurality of micro coaxial cable units are mounted to a slide-type mobile phone.
Preferably, the plurality of micro coaxial cable units include at least one stacked unit composed of a plurality of micro coaxial cables stacked in a direction perpendicular to an arranged direction of the plurality of micro coaxial cable.
In another aspect of the present invention, there is provided a slide-type mobile phone, which includes a body; a display slidably coupled to the body; and a micro coaxial cable assembly including a plurality of micro coaxial cable units arranged in parallel and electrically connecting the body and the display, wherein each of the plurality of micro coaxial cable units includes a body-side fixing portion for fixture to the body; a display-side fixing portion for fixture to the display; and a curving portion forming curves between the body-side fixing portion and the display-side fixing portion, wherein the curving portion is configured such that an angle between a straight line connecting a rightmost point and a leftmost point of the curves and a bottom surface of the body is in a range greater than 0 degree but smaller than 90 degrees.
Preferably, radiuses of curvature of the curving portions are increased from any one of two micro coaxial cable units located at an outermost region to the other when the plurality of micro coaxial cable units are mounted to a slide-type mobile phone. As an alternative, the curving portions of the plurality of micro coaxial cable units may be configured to have the same radius of curvature, and the curving portions are movable independently from each other.
Preferably, the plurality of micro coaxial cable units include at least one stacked unit composed of a plurality of micro coaxial cables stacked in a direction perpendicular to a bottom surface of the body.
According to the present invention, a body and a display of a slide-type mobile phone are electrically connected with each other using a micro coaxial cable having a shielding function in itself, so it is possible to eliminate any cumbersome work for installing a separate shielding member to the slide-type mobile phone and to reduce a cost required for installing such a shielding member.
In addition, according to the present invention, the micro coaxial cable is mounted to the slide-type mobile phone to have a sufficient radius of curvature, so a safety standard of the slide-type mobile phone may be satisfied.

Hereinafter, a micro coaxial cable assembly and a slide-type mobile phone having the same according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First Embodiment
Fig. 4 is a plane view showing a micro coaxial cable assembly according to one embodiment of the present invention, Fig. 5 is a projected plane view showing a slide-type mobile phone having the micro coaxial cable assembly of Fig. 4, Fig. 6 is a schematic sectional view taken along the line C-C' of Fig. 5, and Fig. 7 is a sectional view taken along the line B-B' of Fig. 4.
The micro coaxial cable assembly according to the first embodiment of the present invention includes a plurality of micro coaxial cable units 110 arranged in parallel, and a first connector 150 and a second connector 170 respectively coupled to both ends of the micro coaxial cable units 110, as shown in Fig. 4.
When the micro coaxial cable assembly is coupled to a slide-type mobile phone, as shown in Fig. 5, the first connector 150 is coupled to a connection terminal (not shown) formed at a body 210 of the slide-type mobile phone, and the second connector 170 is coupled to a connection terminal (not shown) formed at a display 230 slidably coupled to the body 210. Coupling positions and angles of the connectors 150, 170 may be modified in various ways on occasions, differently from those shown in Fig. 5.
Each of the plurality of micro coaxial cable units 110 includes a body-side fixing portion 112, a display-side fixing portion 114 and a curving portion 116 positioned between the body-side fixing portion 112 and the display-side fixing portion 114.
When the micro coaxial cable assembly is coupled to a slide-type mobile phone, the body-side fixing portion 112 is fixed to the body 210, and the display-side fixing portion 114 is fixed to the display 230. The body-side fixing portion 112 and the display-side fixing portion 114 may be fixed by fixing fixture points 120 to the body 210 and the display 230, additionally fixing at least one point between the connectors 150, 170 and the fixture points 120 to the body 210 and the display 230, or fixing all regions between the connectors 150, 170 and the fixture points 120 to the body 210 and the display 230.
Meanwhile, though it has been illustrated that the fixture points 120 are located differently from coupling points between the connectors 150, 170 and the micro coaxial cable units 110, the fixture points 120 may be located at the same position as the coupling points between the connectors 150, 170 and the micro coaxial cable units 110 as an alternative. In this case, all regions located between the connectors 150, 170 become the curving portion 116.
The curving portions 116 of the plurality of micro coaxial cable units 110 arranged in parallel are formed such that they are gradually longer from the first line to the last line as shown in Fig. 4. When the micro coaxial cable assembly is mounted to the slide-type mobile phone, the plurality of curving portions 116 configured as mentioned above configure curves such that radiuses of curvature of the curves are gradually increased from the first line to the last line as shown in Fig. 5, and such that an angle a between a straight line 126 connecting a rightmost point 122 and a leftmost point 124 of the curve and a bottom surface 212 of the body is in a range greater than 0 degree but smaller than 90 degrees.
When the micro coaxial cable assembly is mounted to the slide-type mobile phone, if the plurality of curving portions 116 are configured as mentioned above, among the plurality of curving portions 116, a curving portion with a minimal radius of curvature (or, a curving portion located at the first line) may have a sufficient radius of curvature, so the micro coaxial cable units 110 may ensure their safety though the display 230 makes over 100,000 linear reciprocations.
Meanwhile, the plurality of micro coaxial cable units 110 may consist of only non-stacked units, only stacked units, or a combination of such non-stacked and stacked units. The non-stacked unit means a unit composed of one micro coaxial cable 128 as shown in (a) of Fig. 7, and the stacked unit means a unit including a plurality of micro coaxial cables 128 vertically stacked and a fixing film 130 for fixing the plurality of micro coaxial cables 128 as shown in (b) of Fig. 7. In the stacked unit, the number of stacked micro coaxial cables 128 may be suitably selected in consideration of diameter of the micro coaxial cables 128 and thicknesses of the body 210 and the display 230.
In case the micro coaxial cable units 110 include at least one stacked unit, the width of the micro coaxial cable assembly is decreased, so the width of the slide-type mobile phone may also be decreased. For example, if 40 micro coaxial cables 128 consist of only non-stacked units, the micro coaxial cable units 110 configure 40 lines. However, if they consist of only stacked units, each having four micro coaxial cables 128, the micro coaxial cable units 110 configure 10 lines, thereby decreasing their width by 1/4.
Second Embodiment
Hereinafter, a slide-type mobile phone according to the present invention is explained with reference to Figs. 8 and 9, and the same component as in the first embodiment is not explained here.
Fig. 8 is a plane view showing a micro coaxial cable assembly to be mounted to a slide-type mobile phone according to a second embodiment of the present invention, and Fig. 9 is a projected plane view showing the slide-type mobile phone according to the second embodiment of the present invention. In Figs. 8 and 9, the same component as in Figs. 4 to 7 are indicated by the same reference numeral.
Identically to the first embodiment, the slide-type mobile phone according to the second embodiment of the present invention includes a body 210, a display 230 and a micro coaxial cable assembly. Also, the micro coaxial cable assembly includes a plurality of micro coaxial cable units 110 arranged in parallel, and a first connector 150 and a second connector 170 respectively coupled to both ends of the micro coaxial cable units 110. Each of the plurality of micro coaxial cable units 110 includes a body-side fixing portion 112, a display-side fixing portion 114 and a curving portion 116 located between the body-side fixing portion 112 and the display-side fixing portion 114.
