[0002] The signal harness generally includes a male connector and a female connector, and the male connector and the female connector generally have built-in power wires, signal wires, and shielding wires.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 , the present invention provides a technical solution:

[0028] A signal harness with foolproof function, as shown in the instruction manual Figure 1 As shown, including:

[0029] The male connector 1 is provided with a mounting groove 101. In this embodiment, the mounting groove 101 and the mounting head 5 are both circular structures. A plurality of plugs 4 are provided in the mounting groove 101. The plugs 4 are used to cooperate with the jack 6 to electrically connect the male connector 1 and the female connector 2 and to communicate signals.

[0030] A female connector 2, wherein the female connector 2 is provided with a mounting head 5 corresponding to the mounting groove 101, and the mounting head 5 is provided with a socket 6 corresponding to the plug 4;

[0031] The male connector 1 and the female connector 2 are both electrically connected to the signal cable 3, and the signal cable 3 connected to the male connector 1 and the signal cable 3 connected to the female connector 2 are electrically connected by inserting the plug 4 into the socket 6;

[0032] The foolproof component includes a foolproof protrusion 7, which is arranged on the male connector 1, and a foolproof groove 8 is arranged on the female connector 2 corresponding to the foolproof protrusion 7;

[0033] A waterproof component, which is used to waterproof the connection between the male connector 1 and the female connector 2 when the fool-proof protrusion 7 is inserted into the fool-proof groove 8;

[0034] A connecting component, the connecting component includes an electrical connecting mechanism, a temperature detection mechanism, a magnetic connecting mechanism and a separation mechanism. The electrical connecting mechanism is arranged in the anti-mistake groove 8. The electrical connecting mechanism is used to electrically connect the temperature detection mechanism, the magnetic connecting mechanism, the separation mechanism and the signal cable 3. The temperature detection mechanism is arranged on the mounting head 5 and is used to detect the temperature of the plug 4. In this example, the normal operating temperature range of the male connector 1 and the female connector 2 is [-40°C, 105°C]. When the temperature sensor 12 detects that the temperature is outside this range, it means that the temperature fluctuates abnormally. During normal operation, the magnetic connecting mechanism is used to magnetically seal the connection between the male connector 1 and the female connector 2. When the temperature fluctuates abnormally, the magnetic connecting mechanism is used to separate the male connector 1 and the female connector 2 from each other. The separation mechanism is used to separate the male connector 1 and the female connector 2 from each other when the temperature detection mechanism detects that the temperature fluctuates abnormally.

[0035] The waterproof component includes a sealing ring 9, which is used to cooperate with the installation groove 101 to waterproof the connection between the plug 4 and the socket 6 when connected. The sealing ring 9 is arranged on the outside of the installation head 5. When the anti-fool protrusion 7 is inserted into the anti-fool groove 8, the sealing ring 9 will be wrapped around the outside of the installation groove 101.

[0036] The electrical connection mechanism includes a magnetic connection block 10 and a magnetic connection block 2 11. The magnetic connection block 10, the magnetic connection block 2 11 and the magnetic connection block 3 18 are all provided with wires (not shown in the drawings in the specification). The magnetic connection block 10 is set on the anti-mistake protrusion 7, and the magnetic connection block 2 is fixedly connected to the anti-mistake groove 8. When the magnetic connection block 10 and the magnetic connection block 2 11 are attracted to each other, they are used to connect the temperature detection mechanism, the magnetic connection mechanism and the separation mechanism in parallel to the signal cable 3 respectively.

[0037] The temperature detection mechanism includes a temperature sensor 12, which is a thermistor type temperature sensor 12. The temperature sensor 12 is arranged inside the jack 6 and is used to detect the temperature of the connection position between the jack 6 and the plug 4. The temperature sensor 12 is annular, and the plug 4 is inserted into the temperature sensor 12 when in use.

[0038] The magnetic connection mechanism includes a permanent magnet 13 and an electromagnet 14. The permanent magnet 13 is fixedly connected to the side where the sealing ring 9 and the male connector 1 are in contact. The permanent magnet 13 and the electromagnet 14 are both annular structures. The electromagnet 14 is arranged around the outside of the male connector 1. When the magnetic connection block 10 and the magnetic connection block 2 11 are attracted to each other, the electromagnet 14 will be connected in parallel to the signal cable 3. At this time, the electromagnet 14 and the permanent magnet 13 are attracted to each other.

[0039] The separation mechanism includes a mounting block 15, a switching push rod 16, a moving block 17 and a magnetic connection block three 18. The mounting block 15 is fixedly connected to one side of the anti-foolproof protrusion 7. A mounting cavity is arranged inside the mounting block 15. The mounting cavity is used to install the switching push rod 16 and the moving block 17. One end of the switching push rod 16 is fixedly connected to the mounting cavity. The telescopic end of the switching push rod 16 is fixedly connected to the moving block 17 and can drive the moving block 17 to move. The magnetic connection block one 10 and the magnetic connection block three 18 are both arranged on the moving block 17. By controlling the telescopic movement of the switching push rod 16, the magnetic connection block three 18 and the magnetic connection block two 11 are interconnected to pass a reverse current into the electromagnet 14 and thereby change the magnetic field direction of the electromagnet 14. When the magnetic connection block three 18 and the magnetic connection block two 11 are connected to each other, the electromagnet 14 and the permanent magnet 13 repel each other.

[0040] The separation mechanism also includes a self-resetting switch 19 and a separation push rod 20. The self-resetting switch 19 is arranged in the installation cavity. When the magnetic connection block three 18 and the magnetic connection block two 11 are attracted to each other, the installation block 15 will press the self-resetting switch 19 to open the separation push rod 20. The separation push rod 20 is arranged on the male connector 1. The separation push rod 20 is an electric push rod. When separating, the telescopic end of the separation push rod 20 will press against the sealing ring 9 to separate the male connector 1 and the female connector 2 from each other.

[0041] Working principle: When in use, according to the positions of the anti-foolproof protrusion 7 and the anti-foolproof groove 8, the male connector 1 and the female connector 2 are docked with each other when the anti-foolproof protrusion 7 and the anti-foolproof groove 8 correspond to each other. When docking, the magnetic connection block 10 and the magnetic connection block 2 11 will dock with each other. At this time, the temperature detection mechanism, the magnetic connection mechanism and the separation mechanism will be connected in parallel to the signal cable 3 respectively, and the temperature sensor 12 will detect the temperature inside the jack 6 (the connection between the plug 4 and the jack 6) in real time. At this time, the electromagnet 14 and the permanent magnet 13 are attracted to each other and cooperate with the sealing ring 9 to perform a waterproof seal on the connection position of the male connector 1 and the female connector 2. When the temperature is detected When the degree is in an abnormal range, the switching push rod 16 will extend, thereby releasing the connection between the magnetic connection block 10 and the magnetic connection block 2 11 and connecting the magnetic connection block 3 18 and the magnetic connection block 2 11 to each other (when the magnetic connection block 3 18 and the magnetic connection block 2 11 are connected to each other, a reverse current will be passed through the electromagnet 14 to change the direction of the electromagnet 14). When the magnetic connection block 3 18 and the magnetic connection block 2 11 are connected to each other, the moving block 17 will support the self-resetting switch 19 and then start the separation push rod 20. Under the joint action of the separation push rod 20 and the magnetic force (the force of mutual repulsion between the electromagnet 14 and the permanent magnet 13), the male connector 1 and the female connector 2 are separated from each other.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
