Information is transmitted, the duplication, adjustment and enlarging function of signal is completed, extends the length of network with this.It is lost due to existing, online
The signal power of road transmission can gradually decay, and distorted signals will be caused when decaying to a certain extent, therefore can cause to receive wrong
Accidentally.Repeater is exactly to design to solve this problem.It completes the connection of physical circuit, is put to the signal of decaying
Greatly, keep identical as former data.Under normal circumstances, the both ends connection of repeater is identical media, but the repeater having
It can complete the transit working of different media.Theoretically the use of repeater is unlimited, and network also therefore can be unlimited
Extend.
Existing repeater can refer to the patent of invention application No. is 201210182266.3, and tunnel repeater refers to peace
Loaded on the repeater in tunnel, it is mainly used in fields such as railway, water conservancy, electric power, mines.Since the environment in tunnel compares
Badly, dust is more, and rain when air it is very moist, be easy to cause repeater and make moist, to the situations such as short circuit occur, influence
The service life of repeater.
Utility model content
The purpose of this utility model is to provide a kind of dust-proof, moisture-proof tunnel repeaters.
What the purpose of this utility model was realized in：A kind of tunnel repeater, including box body and box cover, the box cover with

The mounting hole of multiple bar shapeds is set, a cooling fin is provided in each mounting hole, the hole wall sealing of the cooling fin and mounting hole is matched
It closes, and a cooling fin part is inserted into box body, a part is located at outside box body；The bottom of the box body is provided with input cable interface
With output cable interface, spring protective set is both provided with outside the input cable interface and output cable interface, the elasticity is anti-
Sheath is provided with cylindrical cable aperture, the shape of spring protective set in truncated cone-shaped and big end downward, the housing of spring protective set
There is hoop.
Further, the box body and box cover are isolation material.
Further, the cooling fin is copper sheet.
Further, the spring protective set is rubber sleeve.
