Abstract
The utility model relates to a transmission line structure, particularly to a transmission line structure which can stably transmit a power supply source of a host machine of a computer to an outer connection type extension device to make the extension device reliably operate. The transmission line has the structure that a connector is fixed at one end of a line body and is connected with the extension device. Two connectors are fixed at the other end of the line body and are connected with the host machine of the computer.
Description
Technical field
The utility model relates to a kind of structure of transmission line, refers to that especially a kind of power supply source of supply of main frame that makes is able to stable transfer to the circumscribed expanding device, with the transmission line structure that makes expanding device turn round really.
Background technology
Circumscribed expanding device in the general computer interface equipment is to utilize transmission line (transmitting device) to be connected with main frame, transmits the communication between main frame and expanding device; This expanding device has a single output/input port and a power control usually, wherein this output/input port is except can providing the transmission line connection, also can supply 500mA following electric current in addition, then optionally control expanding device and external power source source of supply as for power control, for should expanding device when the operation required power supply.
Above-mentioned circumscribed expanding device can be a data and reads cryopreservation device, as hard disk unit etc.Wherein, hard disk unit is connected with main frame by a transmission lines [universal serial of 4PIN (USB)] transmission line, by the data of main frame access hard disk machine inside.
Because the required power supply of this circumscribed expanding device can be obtained by the power supply source of supply of external power source source of supply or main frame, but the convenience during based on use is considered, the common hope of consumer can directly provide the circumscribed expanding device enough power supplys by main frame, and when main frame can't provide enough power supply, just consider to utilize the mode of external power supply, so that sufficient electric power to be provided.
Because, the speed of circumscribed expanding device is more and more fast, and capacity is more and more big, relative needed drive current is also more and more big, in this case, the following electric current of the standard 500mA of USB institute just can't make this circumscribed expanding device drive now, drives and must this circumscribed expanding device be produced by external electric power; Thus, this circumscribed expanding device convenience is in the use not only had a greatly reduced quality, and it is more and more high to drive the ratio of circumscribed expanding device at the main frame electric current.
Summary of the invention
Fundamental purpose of the present utility model is to overcome the deficiencies in the prior art and defective, proposing a kind of structure of transmission line, mainly is to be fixed with a connector in line body one end, to be connected with expanding device, and be fixed with two connectors respectively in the other end of line body, to be connected with main frame.By the two set connectors of an end that above-mentioned transmission line and main frame link, make the power supply source of supply of main frame stably be transferred to the circumscribed expanding device and turn, and must not connect external power supply in addition for it.
Another purpose of the present utility model is: an end that is connected in this transmission line and main frame is respectively equipped with an a connector and a breakout box, this breakout box is provided with an a connector and an output/input port, connects so that other less peripheral device of required electric current to be provided by this output/input port.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with drawings and Examples.
See also the user mode figure of first kind of embodiment of the utility model shown in Figure 1, disclose this transmission line 10 among the figure and mainly be for circumscribed expanding device 20 is connected with main frame 30, adorn 20 and the communication of 30 of main frames to expand really.
Above-mentioned transmission line 10 mainly is to be fixed with a connector 12 in line body 11 1 ends, is connected with the output/input port 21 with expanding device 20; The other end of this line body 11 is fixed with two connectors 12 respectively, and is connected with the output/input port 31 of main frame 30 respectively.
Because these transmission line 10 1 ends have a connector 12 that is connected with expanding device 20, the other end has two connectors 12 that are connected with main frame 30, therefore, when circumscribed expanding device 20 can't be obtained when running during required power supply by traditional USB transmission line, this circumscribed expanding device 20 can utilize transmission line 10 of the present utility model to be connected with the output/input port 31 of main frame 30, stably be transferred to circumscribed expanding device 20 with power supply source of supply, turn round directly to make this circumscribed expanding device 20 by main frame 30.
Moreover, because this transmission line 10 takies two output/input ports 31 when being connected with main frame 30, so be to avoid the output/input port 31 on the main frame 30 that not enough situation takes place, so the structure of this transmission line 10 promptly is embodied as situation shown in Figure 2.
Above said content and illustrated embodiment only are preferable enforcement example of the present utility model, and the personage who knows this technology generally all should be included in the scope of claims of the present utility model according to the various variations that the utility model spirit makes.
Claims (2)
1. the structure of a transmission line, this transmission line, is characterized in that to carry out communication and the power supply transmission between main frame and expanding device for the circumscribed expanding device is connected with main frame:
