## Background
BACKGROUND
1. Technical Field
The present invention relates to a transmission line. More particularly, the present invention relates to a transmission line with rotatable connector.
2. Related Art
With the development of the technology, all kinds of electronic, communication and multi-media devices, such as computer, cell phone, digital camera, DVD, HD television, have been continuously updated. The electrical signal and message between these products may be transferred by a transmission line. When a transmission line is connected to the port of an electronic device, the signal can be transmitted from an electronic device to another electronic device to get the devices connected.
As known to the public, the transmission line may usually be embedded in the connector at the front end of the body and the electronic terminals inside of the connector may be derived from the rear end of the body to weld with wires. Though plastic injection method is generally used to seal wire with the connector, the junction between wires and connector is usually covered by bended soft material to avoid the breakup of the wires after being repeatedly bended and therefore to avoid the short circuit. However, when the transmission line is repeatedly bended or is bended in one direction for a long period, the junction may break up at the bended place. In addition, the junction of the transmission line usually has non-rotatable structure and when the inserted space or direction has limitation, the junction cannot be inserted properly and causes inconvenience.

In this embodiment, the insulated body 10 may include a base 11 and a cover 12. The base 11 may include a half of the opening slot 111 and a half of the sliding slot 112. The cover 12 may include the other half of the opening slot 121 and the other half of the sliding slot 122. The base 11 and the cover 12 may combine together to form the opening slot 101 from two half opening slots 111 and 121 and to form the sliding slot 102 from two half sliding slots 112 and 122.
The connector 20 may be installed in the storage space 100. One end of the connector may protrude from the opening slot 101 to be engaged with another connector.
A secured base 25 may be installed at the rear of the connector 20. The secured base 25 may include a plurality of grooves 250. One end of the transmission line 30 may be embedded into the storage space and may be electrically connected with the connector 20 while the other end may extend out of the insulated body. The transmission line 30 may include a plurality of wires 31, which may respectively be embedded in the grooves 250 of the secured base 25. In this embodiment, the connector 20 may be a connector with a High-Definition Multimedia Interface (HDMI), which may not limit the scope of the claims.
