Motor encoder wire with shielding function

Abstract

The utility model belongs to the technical field of motor encoder wires, and particularly relates to a motor encoder wire with a shielding function, which comprises an encoder wire body, two ends of the encoder wire body are connected with butt joints, and the surface of the encoder wire body is sleeved with fixing sleeves connected with the butt joints. The surface of the butt joint is further connected with a binding band, a first sealing ring and a second sealing ring are installed in the fixing sleeve, and the first sealing ring and the second sealing ring are symmetrically distributed up and down. Through cooperation between the protection sleeve and the anti-abrasion sleeve, when the encoder wire body is bent, the anti-abrasion sleeve generates extrusion at the connecting position, and therefore the encoder wire body is bent. The situation that an insulating layer on the surface of the encoder wire body is damaged due to the fact that the encoder wire body is subjected to overlarge bending force is reduced, then the sealing performance between the fixing sleeve and the butt joint is improved through the use of a first sealing ring and a second sealing ring, and therefore the protection and sealing effects are achieved.

Description

Technical Field

[0001] The utility model belongs to the technical field of motor encoder lines, and in particular relates to a motor encoder line with a shielding function. Background Art

[0002] Motor encoder cables, also known as motor encoder connection cables or encoder cables, are cables that connect motor encoders to control systems (such as PLCs, drives, or controllers). The main function of these cables is to transmit the electronic signals (such as position, speed, or direction) generated by the encoder to the control system for precise control and feedback.

[0003] During the use of the motor encoder line, it is necessary to connect the butt joint to connect with the motor, and a fixing sleeve is provided at the connection between the motor encoder line and the butt joint to reduce the movement of the motor encoder line, and then the fixing sleeve is connected to the butt joint for fixing. However, the connection between the existing motor encoder line and the fixing sleeve lacks certain protection, which causes the motor encoder line to be easily squeezed with the fixing sleeve during bending and use. If the extension is too large, it is easy to cause the insulation layer outside the motor encoder line to be damaged, thereby increasing the safety of the motor encoder line. Utility Model Content

[0004] The purpose of the utility model is to provide a motor encoder line with a shielding function, aiming to solve the problem in the prior art that the connection between the existing motor encoder line and the fixed sleeve lacks certain protection, which causes the motor encoder line to be easily squeezed with the fixed sleeve during the bending process. If this happens for a long time, it is easy to cause the insulation layer outside the motor encoder line to be damaged, thereby increasing the safety of the use of the motor encoder line.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a motor encoder line with a shielding function, comprising an encoder line body, two ends of the encoder line body are connected with docking joints, the surface of the encoder line body is sleeved with a fixing sleeve connected to the docking joint, the surface of the docking joint is also connected with a binding strap, a first sealing ring and a second sealing ring are installed inside the fixing sleeve, and the first sealing ring and the second sealing ring are symmetrically distributed up and down, the bottom end of the fixing sleeve is connected with a protective sleeve, the bottom outer wall of the protective sleeve is connected with screws, and the bottom end of the protective sleeve is provided with an anti-wear sleeve.

[0006] As a preferred motor encoder line with shielding function of the utility model, the encoder line body is composed of an insulating layer, a pressure-resistant layer, a shielding layer and a circuit, and the insulating layer, pressure-resistant layer, shielding layer and circuit are arranged in sequence from the outside to the inside.

[0007] As a preferred embodiment of the utility model of a motor encoder cable with a shielding function, the fixing sleeve is sealedly connected with the docking head through the first sealing ring and the second sealing ring, and the fixing sleeve and the docking head are threadedly connected.

[0008] As a preferred embodiment of the motor encoder cable with shielding function of the utility model, the first sealing ring and the second sealing ring are made of food-grade rubber material.

[0009] As a preferred embodiment of the motor encoder cable with shielding function of the utility model, the anti-wear sleeve is made of ABS plastic material, and the bottom end of the anti-wear sleeve is arc-shaped.

[0010] As a preferred embodiment of the motor encoder cable with shielding function of the utility model, the anti-wear sleeve is fixedly connected with the protective sleeve by a screw.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model cooperates between the protective sleeve and the anti-wear sleeve so that the anti-wear sleeve at the connection is squeezed when the encoder line body is bent, thereby reducing the situation where the encoder line body is subjected to excessive bending force and causing the surface insulation layer to be damaged. Subsequently, through the use of the first sealing ring and the second sealing ring, the sealing between the fixed sleeve and the docking joint is improved, thereby playing a protective sealing role.

[0019] 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.

[0020] See also Figure 1-4 The utility model provides the following technical solutions: a motor encoder cable with a shielding function, comprising an encoder cable body 1, two ends of the encoder cable body 1 are connected with docking joints 2, the surface of the encoder cable body 1 is sleeved with a fixing sleeve 3 connected to the docking joint 2, the surface of the docking joint 2 is also connected with a binding strap 9, a first sealing ring 4 and a second sealing ring 5 are installed inside the fixing sleeve 3, and the first sealing ring 4 and the second sealing ring 5 are symmetrically distributed up and down, the bottom end of the fixing sleeve 3 is connected with a protective sleeve 6, the bottom end outer wall of the protective sleeve 6 is connected with a screw 8, and the bottom end of the protective sleeve 6 is provided with an anti-wear sleeve 7.

[0021] Preferably, the encoder line body 1 is composed of an insulating layer 101, a pressure-resistant layer 102, a shielding layer 103 and a circuit 104, and the insulating layer 101, the pressure-resistant layer 102, the shielding layer 103 and the circuit 104 are arranged in sequence from the outside to the inside.

[0022] During specific use: the encoder line body 1 can reduce external interference through the shielding layer 103, thereby improving the accuracy of transmission instructions. At the same time, the pressure-resistant layer 102 increases the overall strength of the encoder line body 1, and the insulating layer 101 improves the safety of the encoder line body 1 to prevent electric shock.

[0023] Preferably, the fixing sleeve 3 is sealedly connected to the butt joint 2 via the first sealing ring 4 and the second sealing ring 5, and the fixing sleeve 3 and the butt joint 2 are threadedly connected.

[0024] When used specifically, the connection between the fixing sleeve 3 and the butt joint 2 is made so that the first sealing ring 4 and the second sealing ring 5 are located at the connection between the fixing sleeve 3 and the butt joint 2, thereby sealing the gap between the fixing sleeve 3 and the butt joint 2.

[0025] Preferably, the first sealing ring 4 and the second sealing ring 5 are made of food-grade rubber material.

[0026] When used specifically, the first sealing ring 4 and the second sealing ring 5 are used without generating toxic substances that harm the environment.

[0027] Preferably, the anti-wear sleeve 7 is made of ABS plastic material, and the bottom end of the anti-wear sleeve 7 is in an arc shape.

[0028] When in use, the arc-shaped anti-wear sleeve 7 at the bottom reduces the squeezing force when the encoder cable body 1 is bent, and avoids damage to the outer insulating layer 101 of the encoder cable body 1 caused by the right-angle shape.

[0029] Preferably, the anti-wear sleeve 7 is threadedly fixedly connected to the protective sleeve 6 via screws 8 .

[0030] When used specifically, the anti-wear sleeve 7 is conveniently connected to the protective sleeve 6 for use, so that the anti-wear sleeve 7 is easy to install.

[0031] Working principle of the utility model: when the encoder line body 1 is assembled and used, first take out the fixing sleeve 3 and put it on the encoder line body 1, then connect the two ends of the encoder line body 1 to the docking joint 2, and the connection method of the line 104 belongs to the existing mature technology, and then the specific connection method is described in detail. Then, after the encoder line body 1 is connected to the docking joint 2, push the fixing sleeve 3 close to the bottom end of the docking joint 2, and then thread it to the bottom end of the docking joint 2. At this time, the first sealing ring 4 and the second sealing ring 5 are located at the connection between the fixing sleeve 3 and the docking joint 2, sealing the fixing sleeve 3 and the docking joint 2. The gap in the connection improves the sealing between the fixed sleeve 3 and the docking joint 2, thereby playing a protective sealing role. Subsequently, the protective sleeve 6 at the bottom end of the fixed sleeve 3 and the anti-wear sleeve 7 at the bottom end of the protective sleeve 6 are also sleeved on the surface of the encoder wire body 1. When the encoder wire body 1 needs to be bent for use, the encoder wire body 1 will bend at the bottom end of the anti-wear sleeve 7. At the same time, since the bottom end of the anti-wear sleeve 7 is in an arc shape, the squeezing force between the encoder wire body 1 and the anti-wear sleeve 7 is reduced, avoiding damage to the insulating layer 101 outside the encoder wire body 1, thereby improving the safety of the encoder wire body 1.
