Description
technical field:
The utility model relates to a kind of checkout gear, particularly relates to a kind of E1 signal transmitting and receiving checkout gear with deixis.
background technology:
In optical fiber telecommunications system, especially in digital distribution frame.A large amount of coaxial cable carries out E1 signal redirect, docking according to Equipments Setting can be there is; the easy phenomenon occurring transmitting-receiving wrong; and a pair coaxial cable of E1 signal if there is interruption; attendant can carry out the plug of more than twice usually repeatedly; and just can make accurate judgment in conjunction with the alarm instruction of webmaster; although attendant also can use universal instrument, E1 Error Detector checks, program and operation relatively loaded down with trivial details.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of structure simple, be easy to carry, plug and socket flexible combination, can solve in optical fiber telecommunications system in very short time, the E1 signal transmitting and receiving checkout gear that the sending and receiving of E1 signal, switching judge.
The technical solution of the utility model is: a kind of E1 signal transmitting and receiving checkout gear with deixis, comprise plug, socket, diode, described plug is L9 model coaxial cable plug, and described diode both positive and negative polarity is connected with the screen of plug and heart yearn respectively, and is structure as a whole.
The mutual fit of described plug and socket, described plug is provided with cap after plug, and after plug, cap is provided with circular hole.
The beneficial effects of the utility model are:
1, the utility model cost is low, can solve in optical fiber telecommunications system in very short time, and the sending and receiving of E1 signal, switching judge, plug and socket flexible combination, and structure is simple, be easy to carry.
2, the utility model L9 type coaxial cable plug can meet the testing requirement of most of E1 interface, and matches with socket, expands the scope of application, and becoming clear as index signal with diode, convenient and swift.
3, the utility model material source is extensive, and physical structure is simple, can not cause any damage to communication equipment.
4, the utility model reduces the workload of communication speciality operation maintenance personnel, improve the docking efficiency of equipment cable, and the cost of material and making is extremely low, can expand to the corollary apparatus of digital distribution frame product, be user-friendly to.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the E1 signal transmitting and receiving checkout gear with deixis.
Fig. 2 is the E1 signal transmitting and receiving checkout gear circuit connection diagram with deixis.
embodiment:
Embodiment: see in Fig. 1 and Fig. 2, figure, 1-plug, 2-socket, 3-diode, cap after 4-plug.
Have the E1 signal transmitting and receiving checkout gear of deixis, comprise plug 1, socket 2, diode 3, plug 1 is L9 model coaxial cable plug, and diode 3 both positive and negative polarity is connected with the screen of plug 1 and heart yearn respectively, and is structure as a whole.
Plug 1 and socket 2 be fit mutually, plug 1 is provided with cap 4 after plug, and after plug, cap 4 is provided with circular hole.
During use, plug 1 is inserted in and need tests on the e1 port of confirmation, when diode 3 lamp is glittering, confirm that institute's spigot mouth is transmitting terminal, correctly can confirm the Transmitting and Receiving End of transmission equipment side and end side according to this, and make correct docking, also can utilize alternately thread-changing mode, can make accurate judgment fast to the break-make of cable and joint, socket 2 can also be utilized to carry out the detection of other specification cable.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
