Abstract
The invention discloses a lead seal protection device for a round cable connector. The lead seal protection device comprises a socket and a plug. A plug locking nut is arranged at the front end of the plug, a locking piece ring is added at the front end of the plug locking nut, the locking piece ring is arranged between the plug locking nut and the socket, a threaded hole for lead sealing a screw is formed in the locking piece ring, a protection ring sleeves the periphery of the plug locking nut, a hole for penetrating the lead seal screw is formed in the protection ring, and the locking piece ring and the protection ring are connected through the lead seal screw. The lead seal protection device prevents the cable plug from being pulled out randomly in the equipment instrument use process and causing accidents caused by damage to the equipment instrument or data loss. Though the device cannot prevent violent damage, unrecoverable depredation can be reserved after man-made destruction by means of the lead seal, and responsibilities can be analyzed favorably.
Description
Technical field
The present invention relates to cable-to-cable connector technical field, in particular, relate to a kind of lead sealing protective device for round cable connector.
Background technology
Carry out cable by socket plug to connect, very general in equipment and instrument, on some important cable sockets or plug, some mark forbidding plugging or instructions can be done.Relate to the plug portion of individual interest or special important use at some, must be able to ensure not extracted arbitrarily or arbitrarily, ensure that instrument and equipment normal safe runs.
At present, in equipment and instrument, carrying out the socket plug that cable connects, being extracted arbitrarily or arbitrarily preventing, not very simple and easy effective safeguard procedures.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of lead sealing protective device being used for round cable connector that can prevent to be extracted from socket by cable plug in unauthorized situation.
The present invention is used for the lead sealing protective device of round cable connector, and the technical scheme adopted is:
Comprise the socket and plug that connect for cable, it is characterized in that, described plug head arranges plug locknut, installs locking plate ring additional in plug locknut front end, and locking plate ring is stuck between plug locknut and socket, locking plate ring is arranged the screwed hole being used for lead sealing screw; Guard ring is enclosed within plug locknut periphery, and guard ring arranges the hole for wearing lead sealing screw, locking plate ring and guard ring is connected together by lead sealing screw.
Gap is left between described guard ring and plug locknut.
Described guard ring axial length is greater than plug locknut axial length.
Locking plate ring can prevent this device to be pulled out, and guard ring can prevent turn plug locknut, and lead sealing screw prevents from arbitrarily dismantling this device.
The present invention has following beneficial effect:
The present invention can prevent equipment and instrument in use, and cable plug is arbitrarily extracted, cause instrument and equipment damage or loss of data accidents caused.Although the present invention cannot anti-violence damage in advance, due to the effect of lead sealing, after artificial destruction, expendable depredation can be left, be beneficial to analysis responsibility.The production of this device, installation, convenient disassembly, practical.
Under avoiding occurring in unauthorized situation, the resist technology that plug is extracted from socket.This technology, to the instrument and equipment connected with plug, prevents in use, and plug is pulled out in unauthorized situation, causes equipment fault or data transmission fault.Good preventive effect is played for proterctive equipment instrument, reduces instrument fault.No matter be adopt mould to produce in enormous quantities, or all very simple by machining apparatus processing, cost is also lower.Produce, install, convenient disassembly, fail safe and practical.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention cutaway view.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, apparatus of the present invention comprise the socket 1 and plug 2 that connect for cable, and described plug head arranges plug locknut 3, installs locking plate ring 4 additional in plug locknut front end, locking plate ring is stuck between plug locknut and socket, locking plate ring is arranged the screwed hole being used for lead sealing screw; Guard ring 5 is enclosed within plug locknut periphery, and guard ring arranges the hole for wearing lead sealing screw, locking plate ring and guard ring is connected together by lead sealing screw 6.Gap is left between described guard ring and plug locknut.Described guard ring axial length is greater than plug locknut axial length.
During use, first protective ring is inserted in plug, then by locking plate ring set in plug locknut front end, then screws plug locknut.With lead sealing screw through the hole on protective ring, be screwed on locking plate ring, locking plate ring and protective ring are coupled together.In the hole of lead sealing screw, penetrate lead sealing line, stamp lead sealing.
Claims (3)
