## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to an electrical interconnection device, and more particularly to an electrical interconnection device which has two connector members interconnected together and capable of swiveling with respect to one another.
2. Description of Related Art
An electrical interconnection device is used for connecting two electronic devices. There are many different kinds of electrical interconnection devices, such as cable connector assembly and an electrical adapter. The cable connector assembly is mainly used for connecting two electronic devices relatively far away from each other; while the electrical adapter is utilized for connecting two electronic devices neighbored each other and usually have different I/O interfaces.
U.S. Pat. No. 6,343,957 issued to Kuo on Feb. 5, 2002 discloses a DVI electrical adapter for electrically connecting a monitor to a host computer having different interfaces. The electrical adapter includes a combined digital & analog receptacle connector, a digital-only plug connector, two printed circuit boards joined between the plug connector and the receptacle connector, an insulative housing insert molded over a center of the electrical adapter and a pair of elongated fasteners. The elongated fasteners project through two sides of the insulative housing and include a first fixing end and a second fixing end. The second fixing end engages with nuts of a complementary receptacle connector mounted on the host computer. The first fixing end has a threaded recess accepting screws from a cable plug connector attached to the monitor. However, the receptacle connector and the plug connector of the aforementioned electrical adapter are not able to swivel with respect to one another, which may restrict usage of the electrical adapter in certain field.
U.S. Pat. No. 5,658,152 issued to Selker on Aug. 19, 1997 introduces a swivel plug. The plug is has male and female plug portions which pivot 180 degree, with respect to one another about a common pivot axis between first and second positions. A plurality of male and female electrical contact pairs slidably engage one another and pivot about the common pivot axis. Male and female bodies, which receive the electrical contact pairs, also pivot with respect to one another about the common pivot axis. The male and female bodies and the male and female electrical contact pairs are arranged in a novel relationship to mutually retain one other for the pivotal movement. The swivel plug eliminates the need for an electrical cord between an adapter of a laptop computer and a wall receptacle which has a downwardly located ground receptacle or a wall receptacle which has an upwardly located ground receptacle. The swivel plug also enables plugging a computer adapter or a typical extension cord into a receptacle where there is a rigid space constraint. However, an joint portion between the male and female electrical contact pairs may loosen and fail to achieve good electrical connection therebetween.
Hence, an improved electrical interconnection device is highly desired to overcome the aforementioned problems.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an improved swiveled electrical interconnection device.
In order to achieve the object set forth, an electrical interconnection device in accordance with the present invention comprises a first connector having an insulated housing and at least a pogo type contact mounted to the insulated housing; a second connector having base portion and a terminal assembled to the base portion, said terminal having an arc-shaped mating segment; and the first connector pivotally linked to the second connector, with the insulated housing of the first connector disposed adjacent to the base portion of the second connector, the contact pressing onto and sliding along the mating segment of the terminal while the first connector and the second connector are swiveled with respect to one another.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The first connector 1 includes a first insulated housing 11, a number of first contacts 12 mounted to the first insulated housing 11 and a metallic shell 13 enclosing the first insulated housing 11. A pair of flange portions 111 are respectively formed at lateral sides of a rear section of the first insulated housing 11. A board member 110 is secured between the pair of flange portions 111 and rearward extends beyond back surface of the first insulated housing 11. A number of conductive pads 1102 are arranged on a surface of the back segment of the board member 110. The conductive pads 1102 are electrically connected to rear portions of the first contacts 12. However, in alternative embodiment, the conductive pads 1102 may be parts of the rear portions of the first contacts 12.
The first connector 1 further includes a second insulated housing 14. The second insulated housing 14 has a rectangular-shaped main body 140 and a pair of arm portions 142 extending forwardly from lateral sides of a front surface thereof. The pair of arm portions 142 further have two grooves 1420 defined in inner sides thereof. The board member 110 is held between the pair of arm portions 142, with lateral edges of a back portion thereof received in the two grooves 1420 of the arm portions 142. Thus, the first insulated housing 11 and the second insulated housing 14 are combined together to form an insulated housing unit. However, it should note that the housing unit may be one-piece element member, without separated two individual segments. Two apertures 1404 are defined in an up section the main body 140 and another pair of apertures 1405 are defined in a low section of the main body 140. A number of contact passages 1402 pass through a front and back surface of the main body 140.

Each of the second terminals 25 has a semi-circular shaped mating segment 251 located in a peripheral portion of the base portion 20 and two L-shaped tail portions 253 extending inwardly from ends of the mating segment 251 and disposed adjacent to one another. The tail portions 253 hold the panel member 23 and are soldered to distal ends (not numbered) of the first terminals 220. The base portion 20 is made of insulative material and molded over the tail portions 253 of the second terminals 25, the panel member 23 and a rear segment of the mating portion 22. However, it is noted that the mating segment 251 may be configured to be arc or curved shapes.
