Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mobile phone connector, particularly
to a compact and thin mobile phone connector for connecting a DC
charging plug with a mobile phone.
2. Description of the Prior Art Charging device is the essential
equipment of a mobile phone. A conventional mobile phone connector
is generally equipped with a charging slot for connecting a DC charging
plug with a mobile phone. The charging slot is often defined in
a plastic casing of the mobile phone connector. The plastic casing
is required to be of a certain thickness to ensure the strength
thereof. Therefore, the size of the conventional mobile phone connector
is undesired. FIGS. 8 and 9 illustrate such a conventional mobile
phone connector 70 assembled to a foundation plate 71 of the mobile
phone. The conventional mobile phone connector 70 has a height of
approximately 6.8mm. Such a size does not meet the trend for compactness.
Furthermore, external interference tends to result in an improper
signal transmission of the conventional mobile phone.
SUMMARY OF THE INVENTION
Therefore, an objective of the present invention is to provide
a mobile phone connector with small size.
Another objective of this invention is to provide a mobile phone
connector which effectively shields from undesired signal interference.
A further objective of this invention is to provide a mobile phone
which prevents misconnection of a DC charging plug therewith.
A mobile phone connector of the present invention is characterized
in that: the mobile phone connector has an integral enveloping unit
and an insulating unit received in the enveloping unit. The insulating
unit comprises a first charging terminal unit formed on a side thereof
and a second charging terminal unit extending from an end of the
first charging terminal unit. The enveloping unit, the first charging
terminal unit and the second charging terminal unit defines a DC
charging slot for accommodating a mating DC charging plug. The second
charging terminal unit is shorter than a transverse portion of the
first charging terminal unit for positioning the DC charging plug
in the mobile phone connector.
Another characteristic of the mobile phone connector of the present
invention lies in that, the mobile phone connector has contact point
terminals that can be connected to a fixed charging unit, thereby
providing charging functions to an automobile, an airplane or other
traveling vehicles.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As illustrated in FIG. 1, a mobile phone connector of the present
invention comprises an insulating unit 1, an enveloping unit 2,
a plurality of terminals 3, three contact point terminals 4 and
a pair of charging terminals 5. The insulating unit 1 is rectangular
and defines a plurality of terminal accommodating grooves 10 for
accommodating terminals 3 therein. A contact point accommodating
groove 11 is transversely defined beside a side of the insulating
unit 1, and a pair of contact point accommodating grooves 12 are
transversely defined beside an opposite side of the insulating unit
1. An L-shaped first charging terminal unit 13 is formed on a side
of the insulating unit 1 and has a transverse portion 130 adjacent
a side of the insulating unit 1. A second charging terminal unit
14 extends from an end of the first charging terminal unit 13. The
first charging terminal unit 13 and the second charging terminal
unit 14 define a connecting space 15 therebetween. The second charging
terminal unit 14 is slightly shorter than the transverse portion
130 of the first charging terminal unit 13 for positioning a mating
DC charging plug 61, thereby preventing incorrect insertion of the
DC charging plug 61 into the connecting space 15. A pair of side
openings 131, 141 are respectively defined in the first and the
second charging terminal unit 13, 14 and are opposing to each other.
Further referring to FIGS. 4 and 5, the enveloping unit 2 is integrally
formed of a metal sheet for shielding the insulating unit I therein.
A position post 20 upwardly extends from an edge of each lateral
side of the enveloping unit 2 for positioning the mobile phone connector
onto a circuit board 60 (shown in FIG. 7). A pair of stop plates
21 are bent respectively from front edges of an upper side and a
lower side (not labeled) thereof for abutting against a side of
the circuit board 60. A flexible check plate 22 is punched inwardly
and slantwise from the lower side of the enveloping unit 2. The
check plate 22 has a thickness gradually reduced towards a free
end thereof for enhancing flexibility. The check plate 22 forms
a step part 221 adjacent the lower side of the enveloping unit 2
for enhancing resiliency thereof.
In assembly, referring to FIGS. 2 and 3, the terminals 3 are respectively
received in the terminal accommodating grooves 10. The contact point
terminals 4 are respectively received in the first contact point
accommodating groove 11 and the second contact point accommodating
grooves 12. The enveloping unit 2 shields the insulating unit 1
therein. The charging terminals 5 are respectively received in the
side slots 131, 141 and are opposing to each other. The enveloping
unit 2, the first charging terminal unit 13 and the second charging
terminal unit 14 forms a DC charging slot 16 for receiving a mating
portion (not labeled) of a mating DC charging plug 61 therein (shown
in FIGS. 4 and 5).
With reference to FIGS. 4 and 5, the mating portion of the DC charging
plug 61 is received in the DC charging slot 16. The check plate
22 extends into the DC charging slot 16 and presses against the
DC charging plug 61 for firmly clamping the DC charging plug 61
in the DC charging slot 16. A contact end 50 of the DC charging
plug 61 is received in the connecting space 15 and electrically
connects with the charging terminals 5.
As shown in FIGS. 6 and 7, the DC charging plug 61 is secured directly
in the enveloping unit 2 while not in the insulating unit 1, so
the whole height of the mobile phone connector is reduced by about
3mm. This design makes the mobile phone connector smaller and lighter.
In conclusion, the invention has the following advantages over
the prior art. The invention has been described using exemplary
preferred embodiments. However, it is to be understood that the
scope of the invention is not limited to the disclosed embodiments.
On the contrary, it is intended to cover various modifications and
similar arrangements. The scope of the claims, therefore, should
be accorded the broadest interpretations so as to encompass all
such modifications and similar arrangements.
