[0033] A waterproof electronic harness with monitoring function, in order to improve the waterproof effect of the electronic harness, such as Figure 1-6 As shown, the wiring harness body is waterproofed by a waterproof component. The wiring harness body includes a connector component, a probe component, and a wire component. The connector component and the probe component are connected by the wire component. The waterproof component includes:

[0034] Threaded sleeve 11: A backing plate 14 is welded to one end thereof, and two backing plates 14 are welded to one end of the connector assembly and one end of the probe assembly respectively;

[0035] Rubber waterproof cover 1: It is sleeved on the outer wall of the wire assembly;

[0036] Expansion sleeve seat 10: It is sleeved on the outer wall of the rubber waterproof sleeve 1, and an expansion plate 9 is welded to the outer wall of one side of the expansion sleeve seat 10;

[0037] Threaded ring 7: It is connected to the outer wall of the threaded sleeve 11 through threads, and the outer wall of one side of the threaded ring 7 is welded with a tightening sleeve 5 through a connecting rod 6;

[0038] By providing the rubber waterproof cover 1, the outer wall of the wire assembly and the connection between the wire assembly, the connector assembly and the probe assembly can be wrapped, and the rubber waterproof cover 1 can effectively play a waterproof role, thereby effectively protecting and waterproofing the outer wall of the wire assembly and the connection between the wire assembly, the connector assembly and the probe assembly;

[0039] In order to effectively ensure the stability of the rubber waterproof sleeve 1 after wrapping, the threaded ring 7 is rotated along the threaded sleeve 11, so that the tightening sleeve 5 moves toward the direction close to the expansion plate 9 during the synchronous rotation. The multiple expansion plates 9 constitute a conical structure. The tightening sleeve 5 shrinks the multiple expansion plates 9 inward during the continuous movement, so that the expansion plates 9 tighten the rubber waterproof sleeve 1 during the shrinkage process, thereby ensuring the stability of the rubber waterproof sleeve 1 and the outer wall of the wire assembly and the connection between the wire assembly and the connector assembly and the probe assembly, thereby preventing the rubber waterproof sleeve 1 from loosening.

[0040] Furthermore, the connector assembly includes a connector housing 4 and a second mounting sleeve 19, the second mounting sleeve 19 is welded to one end of the connector housing 4, and a rubber pad 3 is fixed to the inner wall of one side of the connector housing 4 by bonding, and the connector housing 4 and one of the pads 14 are fixedly connected;

[0041] When in use, the connector housing 4 is installed on the monitoring instrument by insertion. After the probe assembly monitors the mechanism to be monitored, the monitoring data is transmitted to the monitoring instrument through the wire assembly and the connector assembly.

[0042] Furthermore, the wire assembly includes a wire body 18 and a terminal 20, the terminal 20 is fixedly connected to the wire body 18 by a compression method, and the terminal 20 is fixedly connected to the connector housing 4 by a snap-fit ​​method, the outer wall of the wire body 18 is installed with a shielding layer 17 by a wrapping method, and the outer wall of the shielding layer 17 is sleeved with a waterproof layer 16, and the outer wall of the waterproof layer 16 is sleeved with a corrosion-resistant outer jacket 13;

[0043] During installation, after the terminal 20 is connected to the connector housing 4, the shielding layer 17 can effectively prevent electromagnetic interference, the waterproof layer 16 effectively waterproofs the wire body 18 and the shielding layer 17, and the corrosion-resistant outer jacket 13 effectively improves the wear resistance of the wire body.

[0044] The waterproof layer 16 is made of alkyd resin, and the corrosion-resistant outer layer 13 is made of hydrogenated nitrile.

[0045] Furthermore, the probe assembly includes a monitoring probe body 2 and a mounting sleeve 12, wherein the monitoring probe body 2 and the mounting sleeve 12 are integrally formed, and a connecting piece 15 is integrally formed on the outer wall of the monitoring probe body 2, and the connecting piece 15 is fixedly connected to another pad 14, and the end of the wire body 18 away from the connector assembly is electrically connected to the monitoring probe body 2;

[0046] The monitoring probe body 2 can be provided to monitor the mechanism to be monitored.

[0047] Furthermore, a protrusion 8 is integrally formed on the outer circumferential wall of the threaded ring 7;

[0048] The protrusion 8 can increase the friction between the hand and the threaded ring 7 when the threaded ring 7 is rotated.

[0049] Working principle: During installation, first install the rubber waterproof sleeve 1 on the outer wall of the wire body by means of a socket connection, and wrap the two ends of the rubber waterproof sleeve 1 around the installation sleeve 12 and the installation sleeve 2 19 respectively. Then rotate the threaded ring 7 along the threaded sleeve 11, so that the tightening sleeve 5 shrinks and tightens the expansion plate 9 socketed on the outer wall of the rubber waterproof sleeve 1 during the movement, so that the two ends of the rubber waterproof sleeve 1 are limited and fixed by the expansion plate 9 and the expansion sleeve seat 10. Then install the connector assembly between the monitoring instrument by means of a plug-in connection, and then use the monitoring probe body 2 to monitor items such as temperature or humidity of the monitored mechanism.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
