ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a connector, and particularly to a composite connector used in a portable phone for connection with mating connectors for transmitting signals and for connecting to a DC power recharger.
DESCRIPTION OF THE PRIOR ART
As the communication industry develops, the functions and use of portable phones is being improved day by day. Accordingly, the trend in connectors used in portable phones is to integrate many functions in one connector. U.S. Pat. No. 5,812,660 discloses a prior art connector as shown in FIG.
9
. This prior art connector comprises an insulative housing
6
having a rectangular connection recess
611
extending rearward from a front surface
61
. A flat connector
612
and a pair of RF terminals
613
are arranged within the connection recess
611
. The flat connector
612
includes an insulation plate
6121
and signal terminals
7
on upper and lower surfaces of the insulation plate
6121
. The RF terminals
613
are disposed on opposite sides of the flat connector. A pair of metallic reinforcing members
614
is provided on opposite sides of the connection recess
611
, not only to reinforce the thin upper wall of the connection recess
611
, but also to serve as power terminals for recharging the portable phone, by means of a charger. The connector is also provided with a DC jack
615
, which is accessible from the front surface
61
. Battery terminals
8
project diagonally upwardly from the upper left sidewall of the housing
6
for contacting a battery within the portable phone. An integrated mating connector is required to mate with the plate connector
612
and the RF terminals
613
, and it is impossible to use two small size, optional use connectors with this prior art connector. In addition, when the battery is being charged the flat connector and the RF terminals
613
can not be used at the same time, which does not facilitate the consumer's use of the portable phone. Hence, an improved electrical connector is required to overcome the disadvantages of the prior art.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a connector for a portable phone which is thin and which can support many functions.
A second object of the present invention is to provide a connector for a portable phone which can be alternately or simultaneously connected with mating plug connectors connected to a signal transmitting cable and to a DC power recharger cable.
A connector in accordance with the present invention comprises an insulative housing, a plurality of contacts and a shield. The housing includes a first receptacle portion, a second receptacle portion and a barrier separating the first receptacle portion from the second receptacle portion. Each receptacle portion defines a plurality of contact receiving passageways therethrough. A pair of positioning slots is defined beside each receptacle portion. Each contact includes an engaging section, a transition section and a solder tail. The shield encloses the housing and has a locking aperture on a top plate thereof above each positioning slot for locking a mating plug connector in secure connection with a corresponding receptacle portion.
Other objects, advantages and novel feature of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
