Description
Technical field
The utility model belongs to power industry communication technical field, especially relates to a kind of 2M and receives and dispatches detection head.
Background technology
DDF DDF(Digital Distribution Frame) be between digital multiplex equipment, distributing connection equipment between digital multiplex equipment and switch device or non-voice service.Maximum at present on DDF are non-equilibrium 75 ohm of 2M joints (coaxial connector), are mainly used to be connected to form 2M path with 2M cable (SYV class radio frequency coaxial-cable).2M joint cannot display channel state, in 2M path debug process, when particularly docking business with other professional equipments, often there is 2M line transmitting-receiving wrong, connect anti-situation, digital signal can be caused like this to transmit unsuccessfully, business is obstructed, also may cause damage to equipment time serious, affects the normal work of electric power system simultaneously.At present, what field staff connected for transmission equipment 2M line out is that receiving end or the judgement of transmitting terminal can only be supported or carry the instrument and meters such as 2M BER tester and carry out test and solve by the carrier technologies of these districts and cities of Help by Phone, and both having wasted time and energy turn improves construction cost.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide little, lightweight, the easy to operate 2M of a kind of volume and receives and dispatches detection head.
For achieving the above object, the utility model adopts following technical scheme:
A kind of 2M receives and dispatches detection head, it comprises 2M detection head body and light emitting diode group, the inner core of 2M detection head body stretches out from shell with port, the outer surface of outer cover of 2M detection head body is provided with the electroconductive elastic sheet that a thickness is 0.2 ~ 0.6mm, electroconductive elastic sheet one end is fixed on the outer surface of outer cover of 2M detection head body, the other end is free end and with the inner core external part of 2M detection head body towards consistent, there is between the shell of electroconductive elastic sheet and 2M detection head body the angle of 2 ° ~ 3 °, the electrode input end of light emitting diode group, negative input is positioned at the end of shell with the inner core of 2M detection head body respectively, outer casing inner wall welds together, light emitting diode group is positioned at the cover top portion of 2M head, light emitting diode group is formed in parallel by two direct plugging-in light emitting diodes.
Described 2M receives and dispatches detection head, the free end of its electroconductive elastic sheet is provided with a projection.
Owing to adopting technical scheme as above, the utility model has following superiority:
This 2M receives and dispatches detection head, its structure is simple, cost of manufacture is low, easy to operate, utilize the characteristic of light emitting diode to be arranged on 2M detection head body, during use, 2M is received and dispatched detection head and be inserted on a 2M terminal inner core of DDF DDF, press the shell of the electroconductive elastic sheet contact 2M terminal of 2M detection head body simultaneously, observe 2M and receive and dispatch detection head, this port belongs to the transmitting terminal then light emitting diode Chang Liang of signal, and receiving end then light emitting diode is not luminous; Adopt two light emitting diodes in parallel can prevent from damaging when one of them light emitting diode and affecting the situation of proper testing; Safe and reliable, test speed is fast, and accuracy rate is high, increases work efficiency, and guarantees the operation safely and reliably of electric system.
