BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an adjustable connection assembly, and in particular to an adjustable connector with good adaptability.

2. Description of Related Art

When conventional signal cables are electrically connected to electronic devices, a plug positioned at one end of the conventional signal cable is plugged into a corresponding connector. Thus, the electronic devices are electrically connected to the cable signals because the plug and the corresponding connector are electrically connected. However, if the type of the plug of the conventional signal cable is different from that of the electronic device, then there is a need for a converter. The conventional converter cannot be adjustable (change in length or angle), so it is rather difficult to connect corresponding plugs and connectors. It is inconvenient and lacks adaptability.

The first connector1includes a first isolation main body11, a plurality of first terminals12and a first shielding housing13. The first isolation main body11is made of plastic and has a protruding portion111.

The first terminals12are made of metallic material with good conductivity and positioned at the first isolation main body11. One end of the first terminals12extends to the protruding portion111of the first isolation main body11. When the first connector1is plugged into a corresponding connector, each first terminal12is in electrical contact with a corresponding terminal of the corresponding connector.

The first shielding housing13is made of metallic material with good shielding and is box-shaped. The first shielding housing13encloses the protruding portion111of the first isolation main body11and includes an opening131at one end. The opening131is defined by the protruding portion111of the first isolation main body11and used to receive a corresponding connector.

A first housing14is manufactured by injection-modeling and is electrically isolated. Additionally, the first housing14is used to enclose the first isolation main body11, the first terminals12and the first shielding housing13. A first recess141is positioned at a rear end of the first housing14and used to receive the signal cable3.

The second connector2may be a plug, a socket or other electrical connectors (such as USB port or IEEE 1394 interface). The second connector2includes a second isolation main body21, a plurality of second terminals22and a second shielding housing23. The second isolation main body21is made of plastic and has a protruding portion211.

The second terminals22are made of metallic material with good conductivity and positioned at the second isolation main body21. One end of the second terminals22extends to the protruding portion211of the second isolation main body21. When the second connector2is plugged into a corresponding connection port, each second terminal22is in electrical contact with corresponding terminal of the corresponding connection port.

The second shielding housing23is made of metallic material with good shielding and is box-shaped. The second shielding housing23encloses the protruding portion211of the second isolation main body21and includes an opening231at one end. The opening231is defined by the protruding portion211of the second shielding housing23and used to receive a corresponding connection port.

A second housing24is manufactured by injection modeling process and is electrically isolated. Additionally, the second housing24is used to enclose the second isolation main body21, the second terminals22and the second shielding housing23. A second recess241is positioned at a rear end of the second housing24and used to receive the signal cable3. The first connector1and the second connector2may be the same type of connectors or different types of connectors, as shown inFIG. 7.

The signal cable3is positioned between the first connector1and the second connector2. Besides, the signal cable3includes a plurality of conductive wires31, and both ends of the conductive wires31are electrically connected with the first connector12and the second connector22, respectively. The signal cable3is helical-shaped, flexible and retractable so that orientation and length between the first connector12and second connector22are adjustable.

According to the present invention, the first connector1is electrically connected with the second connector2by the signal cable3. Because the signal cable3is flexible and helical, orientation and length between the first connector12and second connector22are adjustable. It is convenient to plug in corresponding connectors (plug or socket) and the present invention has good adaptability.

Reference is made toFIG. 3. According to the second embodiment of the present invention, a connection hole142and a connection pin242are positioned on the rear end of the first housing14of the first connector1and the second housing24of the second connector2, respectively. The connection hole142corresponds to the connection pin242and is adapted to receive the connection pin242. Besides, the connection hole142can be a curved hole, and the connection pin142can be a curved pin, as shown inFIG. 7. When the first connector1abuts against the second connector2, the distance between the first connector1and the second connector2is minimal. The connection pin242is plugged into the connection hole142so that the first connector1is combined with the second connector2. Besides, the signal cable3is received within the first recess141of the first housing14and the second recess241of the second housing24.

The multiple conversion device includes a main body4, and a third connector5is rotatably positioned at the main body4. The third connector5can be a plug, socket or other electrical connector, and the third connector5can be positioned vertically or horizontally. According to the fourth embodiment of the present invention, the third connector5is a socket and positioned horizontally. A rotatable stand51is positioned at the bottom of the third connector5and rotatably positioned on the top surface of the main body4. Thus, the third connector5is rotatable with respect to the main body4and includes a plurality of third terminals52made of metal. The second connector2(or the first connector1) is snapped into or positioned at the main body4, and is electrically connected with the third connector5.

In practice, one connector at one end of a signal cable (not shown) is plugged into the third connector5of the multiple conversion device so that the signal cable is electrically connected with the multiple conversion device. Then, the first connector1(or the second connector2) of the multiple conversion device is plugged into a connector of electronic device (not shown) so that the multiple conversion device is electrically connected with the electronic device by the signal cable.

The fourth embodiment includes different types of the first connector1and the second connector2that are electrically connected and have good adaptability. According to the fourth embodiment of the present invention, the third connector5is rotatable with respect to the first connector1and the second connector2. Thus, when the multiple conversion device is in use, the signal cable does not interfere with the operation of the electronic device so that plugging in and unplugging signal cable is much more convenient.
