[0016] The present invention has the following beneficial effects:

[0017] 1. The wiring harness high-speed electric control connector proposed by the present invention has a display cavity on the surface of the sheath, and a first liquid storage cavity is arranged next to the terminal jack. When the anode terminal is inserted into the cathode terminal, the first liquid storage cavity is squeezed to inject colored flame retardant liquid into the display cavity, and color strips of different lengths are displayed in the display cavity.

When the three anode terminals 1 are respectively inserted into the three cathode terminals 3, three color bars of unit length are displayed in the display chamber 31. Figure 7 .

[0040] The wiring harness high-speed electric control connector proposed by the present invention has a display cavity 31 on the surface of the sheath 2, and a first liquid storage cavity 7 is arranged next to the terminal insertion hole 6. When the anode terminal 1 is inserted into the cathode terminal 3, the first liquid storage cavity 7 is squeezed to inject the colored flame retardant liquid 30 into the display cavity 31, and color strips of different lengths are displayed in the display cavity 31. It can be judged whether each terminal is well connected according to the length of the color strip, which solves the problem that there are many terminals inside the connector, poor connection is difficult to be discovered in time from the outside, and maintenance is difficult.

[0043] The first electrode sheet 19 and the second electrode sheet 20 are respectively embedded inside the boss portion of the sheath 2, and the two ends of the resistance wire 18 are electrically connected to the first electrode sheet 19 and the second electrode sheet 20 respectively. The upper surfaces of the first electrode sheet 19 and the second electrode sheet 20 are covered with a water-absorbing sheet 21 made of insulating material. The first electrode sheet 19 and the first conductive ring 13 are respectively clamped on the upper and lower sides of the water-absorbing sheet 21, and the second electrode sheet 20 and the second conductive ring 14 are respectively clamped on the upper and lower sides of the water-absorbing sheet 21.

Figure 4 , Figure 5 .

[0044] The male connector includes a waterproof detection terminal 23, the surface of the waterproof detection terminal 23 is wrapped by an insulating layer, and only the upper surface of the waterproof detection terminal 23 exposes the conductive electrode. A U-shaped groove is provided at the end of the cathode terminal 3, and the waterproof detection terminal 23 can be inserted into the U-shaped groove of the cathode terminal 3. The first conductive block 15 is electrically in contact with the cathode terminal 3, and the second conductive block 16 is electrically connected to the conductive electrode of the waterproof detection terminal 23. It should be noted that after the waterproof detection terminal 23 is inserted into the cathode terminal 3, the waterproof detection terminal 23 and the cathode terminal 3 are in a circuit-breaking state.

[0045] In this embodiment, a first conductive ring 13 and a second conductive ring 14 are arranged in the sheath 2, wherein a cathode terminal 3 is electrically connected to the first conductive ring 13, and a waterproof detection terminal 23 is electrically connected to the second conductive ring 14. When water seeps into the sheath 2, the circuits of the first conductive ring 13 and the second conductive ring 14 are turned on, so that the waterproof detection terminal 23 and the corresponding cathode terminal 3 are turned on, and an electrical signal is generated. The electrical signal can be used to monitor whether water has entered the connector, and timely repairs can be carried out to avoid causing greater circuit damage. The connector has the function of monitoring and detecting water ingress, and is safer and more reliable to use. The first conductive ring 13 and the second conductive ring 14 are ring-shaped structures, which can monitor leakage in different directions of the inner cavity of the sheath 2.

[0046] In this embodiment, by providing a second liquid storage chamber 17 in the sheath 2 and a resistance wire 18 therein, the second liquid storage chamber 17 is connected to the display chamber 31, and the first electrode sheet 19 and the second electrode sheet 20 electrically connected at both ends of the resistance wire 18 are insulated and separated from the first conductive ring 13 and the second conductive ring 14 by the water absorbent sheet 21. When the water leakage of the sheath 2 is small, the generated water vapor soaks the water absorbent sheet 21, so that the first conductive ring 13 and the second conductive ring 14 are connected through the resistance wire 18, and the resistance wire 18 is energized and heated, so that the flame retardant liquid 30 expands and enters the display chamber 31. Figure 7 As shown, the length of the color strip in the display cavity 31 is increased, and the position of the display cavity 31 can be observed to determine the location of the leakage point, which provides convenience for rapid maintenance. This method can also be used to check the waterproof reliability of the connector.

[0047] What needs to be strengthened is that when water enters the connector and the connector is short-circuited, the waterproof detection terminal 23 and the corresponding cathode terminal 3 are turned on, and an abnormal electrical signal is generated, which can increase the voltage between the waterproof detection terminal 23 and the corresponding cathode terminal 3, increase the current of the resistance wire 18, generate a large amount of heat, and the flame retardant liquid 30 expands due to heat to a certain upper limit, causing the flexible interlayer plate 12 to burst, and the flame retardant liquid 30 enters the terminal jack 6, which has a flame retardant effect.

[0048] refer to Fig. 9 By filling the elastic particle filler 24 in the display cavity 31 and on the lower side of the diaphragm 9, the elastic particle filler 24 has the characteristics of compression deformation and flow. The elastic particle filler 24 provides a certain extrusion force for the diaphragm 9, so that the diaphragm 9 in normal state fits the inner surface of the transparent sealing plate 8. When the anode terminal 1 is separated from the cathode terminal 3 and the resistance wire 18 is cooled, the colored flame retardant liquid 30 in the display cavity 31 flows back to the first liquid storage cavity 7 and the second liquid storage cavity 17, and the length of the color bar in the display cavity 31 is reset, meeting the requirement of the connector being reusable.

[0049] The wiring harness high-speed electric control connector proposed in the present invention not only has the function of externally displaying whether each terminal is well connected, but also has the function of monitoring water seepage. The position of the display cavity 31 with abnormal color strips can be observed to determine the position of the terminal connection failure. Alternatively, in the case of slight leakage or early leakage, the position of the leakage point can be determined by observing the position of the display cavity 31 with abnormal color strips, and targeted repairs can be performed, such as re-connecting the male connector and the female connector, and replacing the terminal, the sealing ring 4 or the sheath 2.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
