Abstract

The invention relates to a hot-plug connection device. The device is provided with a connection base; the connection base is provided with at least two connection ends; the connection ends are connected in series in a communication line; at least two communication cables and at least one hot-plug unit are also arranged in the connection base; each connection end is connected with at least one communication cable; the hot-plug unit comprises two pieces of memory metals in partial contact; before the connection pin of external equipment is pulled out and the electric connection is cut, the two pieces of memory metal of the hot-plug unit approach to each other and partially contact to realize electric connection; and the two pieces of memory metal of the hot-plug unit are connected with different communication cables respectively. In the invention, two pieces of memory metal can finish electric connection before the connection pin of the external equipment is pulled out by use of the memory characteristic of the memory metal so as to ensure that the communication line is not paused or interrupted.

Description

technical field [0001] The invention relates to the communication field, in particular to a hot plug connection device. Background technique [0002] The signal network surge protector is an important part of the lightning protection system for the communication station. It is widely used in the communication station. It is the main equipment to ensure the safety of the communication line lightning strike. Its technical performance and operation and maintenance status affect the quality of network transmission. and lightning resistance. [0003] The Ministry of Industry and Information Technology requires the performance test of the signal network surge protector used in the communication station, but since the signal network surge protector is often connected in series in the communication line, if the performance test is to be performed, the signal network needs to be removed Surge protectors, which will cause a suspension or interruption of communications.
