When it is necessary to disassemble, replace, or clean the protective plug, first loosen the internal thread fastening cap 9, that is, release the internal thread fastening cap 9 from the support bar 702, until the internal thread fastening cap 9 is separated from the support thread post 6. Then, the protective plug can be pulled out of the connector 11 until the support bar 702 is separated from the support thread post 6. After that, it is necessary to separate the first protective cover 701 from the second protective cover 801, that is, hold the first protective cover 701 with one hand and the second protective cover 801 with the other hand, and then pull them to both sides. Pull until the first protective cover 701 and the second protective cover 801 are separated, so that the positioning clip 803 and the positioning slot 705 are engaged, and the insertion of the docking frame 802 and the docking groove 704 is released.

Then insert the docking frame 802 into the docking groove 704, and then squeeze the two together so that the positioning clip 803 and the positioning slot 705 are engaged. The assembly of the first protective cover 701 and the second protective cover 801 is completed, that is, the assembly of the protective plug is completed. Then insert the cleaned protective plug into the connecting socket 11, and then position the protective plug by the set internal thread fastening cap 9.

That is, first, the internally threaded sleeve 1001 is threadedly connected with the supporting threaded column 6, when the internally threaded sleeve 1001 is rotated to the appropriate position, that is, when the fastening plate 1004 is close to the tail end of the connecting plug 3, one hand holds the fastening plate 1004, so that the fastening plate 1004 is aligned with the tail end of the connecting plug 3, then the other hand continues to rotate the internally threaded sleeve 1001, until the fastening plate 1004 contacts the tail end of the connecting plug 3, then the internally threaded sleeve 1001 is tightened, then the internally threaded sleeve 1001 is threadedly connected with the supporting threaded column 6 on the other side of the connecting socket 11 according to the same operation method, until the fastening plate 1004 is pressed against the other side of the connecting plug 3.

[0041] The ventilation groove 31 is arranged on the connecting plug 3, which is used to provide a simple heat dissipation for the connecting position of the connecting plug 3 and the connecting socket 11, so as to avoid the influence of high temperature. After the connecting plug 3 and the connecting socket 11 are connected and positioned by the fastening pressing plate 1004, the ventilation groove 31 arranged on the connecting plug 3 is exposed outside. In order to avoid the foreign matters entering the ventilation groove 31, the protective plug can be used in cooperation with the protective plug, that is, the protective plug is placed on the connecting plug 3 and above the ventilation groove 31, and the auxiliary sleeve hole 703 on the supporting strip 702 of the first protective cover 701 is aligned with the locking clamping groove 1002 on the inner threaded sleeve 1001.

The supporting plug-in pin 1201 is inserted into the auxiliary sleeve hole 703 on the supporting strip 702, and the position of the supporting plug-in pin 1201 is adjusted until the locking clamping card 1203 at the bottom end of the supporting plug-in pin 1201 is clamped into the locking clamping groove 1002 outside the inner threaded sleeve 1001. The supporting plug-in pin 1201 is arranged as a rubber column, the locking clamping card 1203 arranged at the bottom end of the supporting plug-in pin 1201 is arranged as a rubber card, the clamping of the locking clamping card 1203 and the locking clamping groove 1002 outside the inner threaded sleeve 1001 has corresponding stability, and the arc-shaped auxiliary surface 1204 is arranged on the surface where the locking clamping card 1203 contacts the locking clamping groove 1002, so that the locking clamping card 1203 and the locking clamping groove 1002 are in better contact.

[0042] The protective plug, the connecting plug 3 and the stable assembly have a cooperation effect, and when the temperature of the connecting position of the connecting plug 3 and the connecting socket 11 is too high, the protective plug can be temporarily removed, that is, the ventilation groove 31 on the connecting plug 3 is exposed, and the protective plug is placed above the ventilation groove 31 after the temperature decreases. When the protective plug is removed, the pin head 1202 at the top of the supporting plug-in pin 1201 is pinched by hand, the supporting plug-in pin 1201 is pulled out, the locking clamping card 1203 and the locking clamping groove 1002 are separated, the positioning of the protective plug is released, and then the protective plug is removed. It has good working flexibility.
