Description

Technical Field

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

[0002] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk and the latter is called a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to the working principle, encoders can be divided into incremental and absolute types. The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses is used to represent the size of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the starting and ending positions of the measurement, but not to the intermediate process of the measurement.

[0003] Today's encoders need to transmit signals through encoder cables when in use. Encoder cables will generate a lot of heat when used for a long time and are difficult to use in high temperature environments. The current encoder cables have average fire and high temperature resistance. Encoder cables are easily damaged when in high temperature environments for a long time.

[0029] 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.

[0030] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] 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.

[0032] like Figures 1 to 5As shown, it is an embodiment of the utility model, which relates to a fireproof shielded coding line, including a line body 10, a male plug 20 connected to one end of the line body 10, a terminal connector 11 connected to the side of the line body 10 and a female plug 30 connected to the other end of the line body 10, the line body 10 includes a plurality of conductors 40, a first fireproof layer 12, a shielding layer 13, a high temperature resistant layer 14, a second fireproof layer 15, a flame retardant layer 16, and a sheath layer 17, the plurality of conductors 40 are arranged on the inner side of the first fireproof layer 12; the first fireproof layer 12 is arranged on the inner side of the shielding layer 13; the high temperature resistant layer 14 is arranged on the inner side of the fireproof layer; the second fireproof layer 15 is arranged on the inner side of the flame retardant layer 16; the flame retardant layer 16 is arranged on the inner side of the sheath layer 17.

[0033] Furthermore, if Figures 1 to 3 As shown, the male plug 20 includes a first shell 21, a male plug 22 connected to one end of the first shell 21, and first locking screws 23 are respectively provided on both sides of the first shell 21; the female plug 30 includes a second shell 31, a female plug 32 connected to one end of the second shell 31, and second locking screws 33 are respectively provided on both sides of the second shell 31.

[0034] Furthermore, if Figure 1 As shown, a first heat shrink tube 50 is provided at the connection between the wire body 10 and the male plug 20 , a second heat shrink tube 60 is provided at the connection between the wire body 10 and the female plug 30 , and a plurality of labels are provided on the outer surface of the wire body 10 .

[0035] Furthermore, if Figure 4 As shown, the first fireproof layer 12 is a non-combustible synthetic mica layer. Specifically, the design of the first fireproof layer 12 improves the fireproof performance of the cable, thereby improving the safe service performance of the cable.

[0036] Furthermore, if Figure 4 As shown, the shielding layer 13 is a carbon fiber layer. Specifically, carbon fiber has good flexibility and electromagnetic shielding performance, thus improving the anti-electromagnetic performance of the shielded wire, and can maintain good mechanical properties and extend the service life.

[0037] Furthermore, if Figure 4 As shown, the high temperature resistant layer 14 is a high temperature resistant fiber layer. Specifically, the high temperature resistant fiber layer has good heat resistance, so that the coding line has good high temperature resistance in a high temperature environment, and improves the service life of the coding line.

[0038] Furthermore, if Figure 4As shown, the second fireproof layer 15 is an asbestos cloth fireproof layer. Specifically, asbestos cloth has excellent fireproof, heat-resistant, acid-base corrosion resistance, so the second fireproof layer 15 also has a stable and reliable fireproof effect. The second fireproof layer 15 cooperates with the first fireproof layer 12 to provide double fireproof protection for the coding line, thereby further improving the fire-resistant and flame-retardant effect of the coding line.

[0039] Furthermore, if Figure 4 As shown, the flame retardant layer 16 is a glass fiber cloth layer. Specifically, the glass fiber cloth has good fire retardant performance, insulation performance, heat resistance and corrosion resistance, and high mechanical strength.

[0040] Furthermore, if Figure 4 As shown, the sheath layer 17 is a thermoplastic elastomer protective layer. Specifically, the sheath layer 17 made of plastic elastomer has the excellent properties of high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber, and at the same time has the characteristics of convenient processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion, blow molding and other processing methods. The processing is simple and the cost is low. The high elasticity enables the sheath layer 17 to better protect the coding line and extend the service life of the cable.

[0041] Furthermore, if Figure 4 and Figure 5 As shown, the conductor 40 includes a conductor core 41, an inner sheath 42, and an outer sheath 43. The inner sheath 42 is arranged on the outside of the conductor core 41, and the outer sheath 43 is arranged on the outside of the inner sheath 42; the inner sheath 42 is a polyester imide paint coating, and the outer sheath 43 is a ceramic silicone rubber layer. Specifically, the polyester imide paint coating is used as the inner sheath 42, which is formed by coating the outer surface of the conductor 40 layer 3 with polyester imide paint, and plays an insulating role; ceramic silicone rubber is a new type of fire-resistant insulating material. When the sheath layer 17 is damaged in the case of fire, the temperature rise causes the outer sheath 43 to be ceramicized instead of carbonized, and the formed ceramic body is a good insulating layer and temperature-resistant layer. Therefore, the cable can continue to be used after the fire without replacement.

[0042] The utility model improves the multiple fire retardant and high temperature resistant properties of the coding line through the comprehensive design of the first fireproof layer 12, the shielding layer 13, the high temperature resistant layer 14, the second fireproof layer 15 and the flame retardant layer 16, thereby improving the safety performance of the coding line, improving product quality and extending service life.

[0043] 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.
