Description

Technical Field

[0001] The utility model relates to the technical field of Hall lines, in particular to a waterproof shielded Hall line. Background Art

[0002] The Hall line is mainly responsible for transmitting the Hall signal, which is used to detect the magnetic field and then determine the position and speed information of the motor rotor. The main function of the Hall line in the motor is to improve the control accuracy and efficiency of the motor. By monitoring the position and speed of the motor rotor in real time, the Hall line helps the controller to adjust the rotation speed and direction of the motor more accurately. The working principle of the Hall line is based on the Hall effect. When the current passes through the Hall element, if there is a magnetic field perpendicular to the direction of the current, an electromotive force will be generated in the direction perpendicular to the current and the magnetic field. By measuring the magnitude of this electromotive force, the direction and strength of the magnetic field can be determined, thereby judging the position and speed of the motor rotor. In addition, the Hall line has different functions in different applications. For example, in the field of automation control, Hall sensors are used to measure physical quantities such as temperature, position, and speed.

[0003] The existing Hall wire is easily broken during the pulling process, and its waterproof performance is not very good, and its sealing is not very strong, which can easily cause the internal wires to get damp, thus affecting the normal use of the entire wiring harness. Therefore, we urgently need a waterproof shielded Hall wire to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figures 1 to 4As shown, it is an embodiment of the utility model, which relates to a waterproof shielded Hall line, including a Hall line body 10, wherein the Hall line body 10 includes a line body 11, and the line body 11 includes a sheath layer 20, a waterproof and moisture-proof layer 30, a tensile layer 40, a shielding layer 50, an insulating layer 60, a plurality of conductors 70 and a reinforcing rib 80; the sheath layer 20 is arranged on the outer side of the waterproof and moisture-proof layer 30; the waterproof and moisture-proof layer 30 is arranged on the outer side of the tensile layer 40, and the waterproof and moisture-proof layer 30 includes a waterproof adhesive layer 31, a hygroscopic layer 32, a waterproof glue layer 33 and a moisture-proof paper layer 34; the tensile layer 40 is arranged on the outer side of the shielding layer 50; the shielding layer 50 is arranged on the outer side of the insulating layer 60; the plurality of conductors 70 are arranged on the inner side of the insulating layer 60; and the reinforcing rib 80 is arranged in the center of the plurality of conductors 70.

[0028] Furthermore, if Figure 4 As shown, the Hall line body 10 includes a male plug 12 and a female plug 13, wherein the male plug 12 is connected to one end of the line body 11, and the female plug 13 is connected to one end of the line body 11 away from the male plug 12; a first sealing tube 14 is provided at the connection between the line body 11 and the male plug 12, and a second sealing tube 15 is provided at the connection between the line body 11 and the female plug 13. Specifically, the first sealing tube 14 and the second sealing tube 15 are configured as heat shrinkable tubes, which are used as sealing tubes to effectively protect the sealing of the connection, improve the waterproof performance, and have strong practicality.

[0029] Furthermore, if Figure 1 As shown, the sheath layer 20 includes an outer sheath 21 and a filling layer 22. The outer sheath 21 is arranged on the outside of the filling layer 22, and the filling layer 22 is a flame retardant fiber layer. Specifically, the filling layer 22 is arranged in the gap between the outer sheath 21 and the waterproof and moisture-proof layer 30, so that the internal layers of the waterproof shielded Hall line form a seamless whole, thereby effectively improving the waterproof level. At the same time, the use of flame retardant fiber as the filling layer 22 can improve the flame retardant performance of the waterproof shielded Hall line, and the protection performance is high.

[0030] Furthermore, if Figure 2As shown, the waterproof adhesive layer 31 is arranged below the moisture absorption layer 32 , the moisture absorption layer 32 is arranged below the waterproof mastic layer 33 , and the waterproof mastic layer 33 is arranged below the moisture-proof paper layer 34 . Specifically, the waterproof adhesive layer 31 uses a waterproof sealant, which does not contain toxic aromatic hydrocarbon solvents and is an environmentally friendly product. It has good adhesion to the surfaces of concrete, metal, wood, stone, plastic steel and solar panels. A hygroscopic layer 32 is fixedly installed at the bottom of the waterproof sealant. The hygroscopic layer 32 is a desiccant, which is a substance that can remove part of the moisture in a humid substance. A waterproof glue is fixedly installed at the bottom of the hygroscopic layer 32. The waterproof sealant and the waterproof glue can increase the moisture resistance of the waterproof shielded Hall line while increasing its sealing performance, thereby better preventing moisture from entering the insulating layer 60. A moisture-proof paper is fixedly installed at the bottom of the waterproof glue. The waterproof sealant, waterproof glue and moisture-proof paper in the moisture-proof paper can block external moisture. The hygroscopic layer 32 can absorb the moisture entering the moisture-proof paper, thereby preventing moisture from entering the insulating layer 60 and affecting the normal operation of the waterproof shielded Hall line.

[0031] Furthermore, if Figure 1 As shown, the tensile layer 40 is a polyester fiber layer. Specifically, the tensile layer 40 is made of polyester fiber material, which has the greatest advantages of good wrinkle resistance and shape retention, high strength and elastic recovery, and is strong and durable, thereby improving the tensile protection performance of the waterproof shielded Hall line.

[0032] Furthermore, if Figure 1 As shown, the shielding layer 50 is a carbon nanotube rope layer. Specifically, the electromagnetic shielding layer 50 is formed by using carbon nanotube ropes. Since carbon nanotubes have good electrical conductivity, the shielding layer 50 has a strong shielding effect. Compared with the braided metal wire or rolled metal film in the prior art, the shielding layer 50 has a simple structure and is therefore suitable for low-cost mass production.

[0033] Furthermore, if Figure 1 and Figure 3 As shown, the insulating layer 60 is a ceramic silicone layer, and the outer circumference of the insulating layer 60 facing away from the conductor 70 is evenly distributed with a number of protrusions 61, and the shielding layer 50 is closely arranged above the protrusions 61. Specifically, ceramic silicone rubber is a new type of composite silicone rubber material that can be vitrified at high temperatures. It will maintain all the properties of silicone rubber at room temperature, such as good insulation. When it encounters high temperatures, it will be converted into an inorganic ceramic material. This ceramic material has the advantages of ceramic insulation, heat insulation, fire insulation, water insulation, earthquake resistance, and low thermal weight loss. In the event of a fire, the ceramicized hard shell can play a good role in flame retardancy, fire resistance, fire prevention, and fire insulation. It can withstand up to 3000°C, realizing the role of protecting the waterproof shielded Hall line and effectively ensuring the smooth flow of the line.

[0034] Furthermore, if Figure 1 and Figure 3 As shown, the number of the protrusions 61 is set to five, and a filling gap 62 is provided between two adjacent protrusions 61. Specifically, by providing the protrusions 61, a filling gap 62 between the protrusions 61 is formed. The functions of the gap are, first, to provide a buffer space to improve the toughness of the waterproof shielded Hall line, second, to increase the waterproof space, even if water enters, it is collected by the gap and will not enter the insulation inside, and third, to provide a deformation space for the outer layer material, which can effectively prevent deformation caused by thermal expansion and contraction of the material.

[0035] Furthermore, if Figure 1 As shown, the number of the conductors 70 is set to four, and the four conductors 70 are arranged around the reinforcing ribs 80. Specifically, the reinforcing ribs 80 can be tensile fibers or reinforcing fibers. The tensile fibers are used to enhance the mechanical strength of the cable so that it is not easily torn apart. The reinforcing fibers are used to increase the bending radius of the cable and enhance the bending resistance of the cable. At the same time, they also have a certain tensile resistance, improve the tensile resistance, and are not easily damaged.

[0036] The utility model is provided with a waterproof and moisture-proof layer 30, which effectively blocks external moisture and prevents moisture from entering the conductor 70. It is not easy to be affected by moisture and has a good waterproof effect. The anti-tensile layer 40 is provided to improve the tensile protection performance of the utility model. During use, it can effectively solve the problem that the cable is easily cracked due to the influence of the pulling traction force on the cable, thereby extending the service life.

[0037] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
