Abstract
A solid pipe security unit. Relates to an overvoltage and overcurrent protector on a distribution frame of a communication machine room. The device comprises a shell, a printed board, a light emitting diode, a connecting sheet, a pair of internal lines, a pair of external lines, alarm and grounding, and further comprises a box body, a solid tube, a tin melting block, a PTC (positive temperature coefficient), a fixed sheet, a movable sheet, an alarm sheet, a grounding sheet and a spring. The invention adopts the overvoltage protection of the solid tube and the PTC and thermistor to realize the overcurrent protection performance, and realizes the open circuit of the external wire and the internal wire when the overvoltage and the overcurrent invade.
Description
Technical field
The present invention relates to a kind of protector of communication line, relate in particular to overvoltage, overcurrent protective device on a kind of communication machine room distributing frame.
Background technology
At present, the total machine room of telecom communication circuit in use has a large amount of internal and external line circuit to connect, and under some emergency case, such as thunder and lightning etc., can enter overvoltage, overcurrent by outside line, causes the damage of calculator room equipment.Therefore; people have designed the protector socket on the machine room distributing frame; in this socket, insert Security Unit; when overvoltage and overcurrent invasion; Security Unit is action in time; avoid overvoltage and overcurrent to invade interior lines, effectively protect calculator room equipments such as distributing frame, switch, guarantee the unimpeded of telecom communication circuit.But present disconnection manner mainly is to adopt the mode of outside line ground connection to avoid the overvoltage of outside line and overcurrent to be conducted into interior lines.But this earthing mode can form the concussion electric current, can form the concussion rush of current to interior lines equipment, might cause damage to interior lines equipment.
Publication number is 2694677; name is called the Chinese patent literature of " three utmost point solid pipe safety units "; a kind of Security Unit of three utmost point solid tube circuit is disclosed; its circuit is when meeting overvoltage, overcurrent; by making the protection of interior lines ground connection realization to rear end equipment; this patented technology has certain barrier propterty, and long service life.But ground connection still can form the concussion electric current, still can form the impact of concussion electric current to interior lines equipment, the equipment of rear end, fragile interior lines.
Summary of the invention
The present invention is directed to above defective, a kind of mode of utilizing interior lines and outside line to open circuit is provided, avoid the solid pipe safety unit of overvoltage, overcurrent damage interior lines rear end equipment.
Technical scheme of the present invention is: include shell, printed board, light-emitting diode, brace, a pair of interior lines, a pair of outside line, alarm and ground connection, it also comprises a box body, solid tube, melt block tin, PTC, stator, moving plate, the alarm sheet, ground strip, spring, box body is located in the printed board, be provided with the connection line that pair of parallel is provided with in the box body, be serially connected with ground strip in every connection line respectively successively, melt block tin, solid tube, moving plate, spring, PTC, brace, the end face that melts block tin connects ground strip, ground strip is established groove, the end of melting block tin is provided with mesopore, the groove that alarm sheet sky passes ground strip stretches into mesopore, brace connects interior lines, be connected with stator with moving plate, stator connects outside line.
Its a pair of interior lines leading foot, a pair of outside line leading foot, alarm leading foot, ground connection leading foot are separately positioned on the bottom or are separately positioned on the bottom or the middle part.
The present invention adopts the overvoltage protection of solid tube and PTC, thermistor to realize the overcurrent protection performance, when overvoltage, overcurrent invasion, the heat energy of discharge tube moment generation melts low temperature at Millisecond and melts opening circuit of tin realization outside line and interior lines in the time, effectively protect the interior lines rear end equipment; Simultaneously, low temperature melts tin still alarms the medium that is connected with ground connection, and when overvoltage, overcurrent, low temperature melts the heat that tin sent by solid tube and melts, and the tin that melts of thawing is connected alarm sheet and the ground strip that noncontact is provided with, and realizes alarm function.Deft design of the present invention, the reliability height, the reaction time is short, can effectively protect the equipment of communication machine room.

Embodiment
Establish a box body 15 in printed board 10, the upper end of printed board 10 is provided with light-emitting diode 4.Establish a pair of circuit in the box body 15, successively ground strip 7, molten block tin 2, solid tube 1, moving plate 8, spring 16, PTC3, brace 5 are connected in series respectively in every pair of circuit; Molten block tin 2 is established a mesopore or groove; Ground strip 7 connects ground connection 11 and establishes a groove; Brace 5 connects interior lines 13; Alarm sheet 6 connects alarm 12 and is fixed on the box body 15, and the groove of ground strip 7 is passed in the end, does not contact with ground strip 7, stretches in the mesopore or groove of molten block tin 2, and when molten block tin 2 dissolved, molten tin was connected conducting with ground strip 7 with alarm sheet 6, realizes alarm function; Open a groove and stretch into a stator 9 that connects outside line 14 in the box body side, stator 9 contact moving plates 8, when molten tin 2 melted, spring 16 promoted moving plates 8 and moves, and moving plate 8 is separated with stator 9, realized that outside line 14 and interior lines 13 open circuit.
Two interior lines 13 connect the reed of printed board 10 front upper, and stretch out shell; Two outside lines 14 connect the reed of printed board 10 upper rear portion, and stretch out shell; Alarm 12 and ground connection 11 are arranged on printed board 10 lower ends, connect alarm sheet 6 and ground strip 7 respectively.
Operation principle of the present invention is: when overvoltage, overcurrent invasion, the heat energy that 1 moment of discharge tube produces melts low temperature at Millisecond and melts tin 2 and holding wire 6 is communicated with ground wire 7 and sends alarm signal in the time, simultaneously discharge tube 1 and moving plate 8 push low temperature together and melt tin 2 and move under the promotion of spring 16, thereby moving plate 8 just separates with the stator 9 that is connected outside line and realizes opening circuit of outside lines and interior lines when mobile certain displacement, thereby the realization outside line is opened circuit and sent the function of alarm signal.
