## Abstract

A communication-circuit line protector capable of maintaining reliable connection to a port unit of a communication system, easily checking a disorder or failure of the communication-circuit line protector, and effectively releasing heat generated from an inner portion of the communication-circuit line protector is provided. The communication-circuit line protector include: a housing having a plurality of openings disposed on a side thereof; a ground pin provided to an inner side of the housing, the ground pin having an elastic end portion which cooperates with a lower-side inner wall of the housing opposite thereto to be in close contact with a ground portion, thereby maintain reliable ground contact; and a PCB having the ground pin attached to one side thereof and a conduction member provided to a lower end portion thereof, thereby maintaining good connection at a time of connection to a port.

## Claims

### Claim 1

A communication-circuit line protector comprising:
a housing;
a ground pin provided to an inner side of the housing, the ground pin having an elastic end portion which cooperates with a lower-side inner wall of the housing opposite thereto to be in contact with a ground portion; and
a PCB having the ground pin attached to one side thereof and a conduction member provided to a lower end portion thereof, and
an elastic contact member disposed to protrude from a surface of the PCB so that, when said communication-circuit line protector is inserted to a port of a port unit, said conduction member is pushed to said port, thereby increasing contact between the conduction member and the port,
wherein said housing includes a plurality of openings disposed on a side thereof that release heat from an inner portion of the housing and enable access to and inspection of said PCB, and
wherein said conduction member is disposed on two surfaces of the PCB in order to obtain good conduction and compatibility.

### Claim 2 (depends on 1)

The communication-circuit line protector according to claim 1, wherein a connecting protrusion and a connecting groove are disposed to a lower portion of the housing.

### Claim 3 (depends on 1)

The communication-circuit line protector according to claim 1, wherein an auxiliary connecting member is disposed to one side of a lower portion of the housing.
