Detailed Description

The present invention will be described in further detail with reference to the following examples, which are illustrative of the present invention and are not intended to limit the present invention.

Example 1:

the utility model provides a remote radio changes explosion-proof module for RS485 serial interface, includes shell 5, shell lid 2, mainboard 4 and antenna terminal 1, antenna terminal 1 sets up in the 2 outsides of shell lid, mainboard 4 sets up 2 insides of shell lid and are connected with antenna terminal 1 electricity, shell 5 and shell lid 2 are sealed each other, 5 bottoms of shell are equipped with the cable wire hole, the cable 8 of electricity connection stretches out to the outside of shell 5 through the cable wire hole on mainboard 4, shell 5 with it is full of epoxy 3 to fill in between mainboard 4. In the prior art, the cost of laying a data communication line on an oil field is higher, the operability is poor, and a radio frequency antenna interface is not easy to meet the explosion-proof standard requirement of the oil field, therefore, the utility model discloses just improve to this technical problem, seal the mainboard inside shell 5 and shell cover 2, and fill epoxy resin 3, make the internal hardware module become one by one, the whole structure satisfies explosion-proof level Exdib II CT6, in addition the whole is small, the installation is convenient to use, the radio frequency antenna is directly connected with the internal mainboard to increase the signal intensity and the service life; the mounting bracket 6 can be mounted on the outer side of the equipment and can also be directly connected with the internal structure of the rest equipment through a threaded interface, so that the application is wide.
