ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a communication connector, particularly a compact and lightweight communication connector that is assembled to a mobile phone with communication and charging functions.
2. Description of Related Art
Conventionally, a communication connector related to the present invention is assembled to a mobile phone, such a connector is generally equipped with a DC charging slot to facilitate portability of the mobile phone, as well as charging of sufficient power. As illustrated in
FIG. 8
, a prior art of communication connector
8
is equipped with a conductive terminal
80
and a contact point terminal
81
and a charging terminal
82
for charging purpose. However, a conventional charging slot
83
accommodating the charging terminal
82
is monobloc formed with a connector plastic casing
84
. In other words, the plastic casing
84
has formed a round insert hole, and the charging terminal
82
at the center. Taking into consideration the plastic injection forming process, the integral thickness has a certain proportion, therefore, the size of such a connector cannot be reduced. As shown in
FIG. 9
, the height of a conventional communication connector
1
is approximately at 6.8 mm after it is assembled to the circuit foundation board
90
of a mobile phone. However, such cubic measurements could not meet the current trend for compact size and light weight. Furthermore, high quality of transmitted signals is also required for a mobile phone. The structure of conventional communication connector
1
that is coated merely by plastics could not prevent interference from outside signals, but if a metal obstruction is used to surround it, the integral thickness will be increased, which is not desirable in the design for compactness and light weight.
SUMMARY OF THE INVENTION
It is therefore an objective of this invention to provide a communication connector. The connector will effectively prevent interference of foreign signals by the equipment of an excellent obstruction unit. Its cubic measurements will be lighter and thinner than the conventional models, so as to reduce the integral measurements of the mobile phone, in order to meet the design for compactness and light weight.
CHARACTERISTICS OF THE INVENTION
The present invention of communication connector is characterized in that: the charging slot of the connector is framed by a metal obstruction unit in combination with an insulation unit of the connector, to form a low-profile body. Referring to the main characteristic, the charging slot is framed in a square shape.
Another characteristic of the invention of communication connector lies in that, the metal obstruction unit has a location identifying unit opposite the charging slot, the location identifying unit serves to provide correct insertion and connection to a matching charging plug.
Referring to the above characteristic, the location identifying unit has a long depressed groove on the shorter outside of the obstruction unit and opposite the square shaped charging slot.
