Description

Technical Field

[0001] One or more embodiments of this application relate to the field of cables, and more particularly to a cable joint reactive cone forming device and angle adjustment method and equipment. Background Technology

[0002] The expansion of the cable market demand is driven by industrialization and urbanization, leading to a continuous increase in the demand for power supply and telecommunications network construction. After a cable is laid, to ensure it forms a continuous line, the various sections must be connected as a whole; these connection points are called cable joints. Cable joints are also known as cable ends. Cable joints located in the middle of a cable line are called intermediate joints, while those at both ends of the line are called terminal joints. Cable joints are used to lock and secure the incoming and outgoing cables, providing waterproofing, dustproofing, and vibration protection. Therefore, the preparation of cable joints has always been a crucial step in cable manufacturing. In traditional manufacturing processes, workers need to perform processes such as stripping, insulation layer treatment, welding or crimping of the cable cores, followed by wrapping, protection, and fixing to ultimately form a reliable electrical connection. This process requires a high degree of technical skill and experience and is susceptible to human error, posing certain quality risks.

[0003] Therefore, this application proposes a cable joint reaction force cone forming device and angle adjustment method and equipment, which can effectively improve the manufacturing efficiency and quality of cable joint reaction force cones. While improving efficiency and reducing labor intensity, it ensures that the cable joint reaction force cone is round and smooth, thus guaranteeing the operating quality and life of cable accessories.

When the tail end of the adjusting bolt is obstructed by the push rod extended from the push rod motor, the nut corresponding to the adjusting bolt moves backward or forward along the axis of the adjusting bolt, causing the sanding belt support plate to deflect clockwise or counterclockwise around the central axis of the rotary shaft to adjust the contact angle between the sanding belt and the cable joint.

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0046] The reactive force cone described in this application addresses the problem of electric field stress concentration at cable joints. Cable joints play a connecting and insulating role in power or signal transmission. However, due to changes in the structure and dielectric properties of the cable joint, the electric field distribution is uneven, leading to electric field stress concentration. When a cable joint is subjected to additional electric field stress concentration, it may cause dielectric breakdown, forming a discharge path and causing the cable joint to lose its insulation performance, affecting the safe operation of the entire cable system. Electric field stress concentration also accelerates the aging and deterioration of the joint's insulation material, shortening the joint's service life. Furthermore, electric field stress concentration reduces the reliability of the joint, increasing the probability of failure and affecting the continuity and stability of power or signal transmission. The reactive force cone, through its specific geometry, can alleviate these problems. When external tensile or compressive forces are applied to the cable joint, the reaction force is transmitted through the cable joint, forming a reactive force cone. The presence of this reactive force cone can change the stress distribution at the cable joint, reducing the degree of electric field stress concentration. By distributing the force more evenly within the joint area, the reactive force cone can reduce the peak value of the electric field stress and provide a more balanced electric field distribution. This helps mitigate the risk of dielectric breakdown, extend the life of the joint, and improve the reliability of the entire cable system. Therefore, the angle forming of the reactive cone of a cable joint requires a round, smooth shape, free of warping or sharp corners. However, manual grinding is not only labor-intensive but also has a low success rate, failing to meet the current requirements for forming the reactive cone of cable joints. Therefore, this application proposes a new cable joint reactive cone forming device and angle adjustment method / equipment to solve the above problems.

[0047] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0048] This application provides a cable joint reactive cone forming device, see [link]. Figures 1-3 The cable joint reaction cone forming device includes a sanding belt 1, which is fixed on a sanding belt support plate 2. The sanding belt support plate 2 is mounted on an annular guide rail 4 via a rotating shaft 3. The initial positions of the sanding belt support plate 2 and the annular guide rail 4 are on the same plane. The annular guide rail 4 rotates clockwise or counterclockwise under the drive of a first motor 5, causing the sanding belt 1 to rotate and sand the cable joint 6. An adjusting bolt 7 is also included. The front end of the adjusting bolt 7 is hinged to the annular guide rail 4, and the corresponding nut is hinged to the sanding belt support plate 2. The adjusting bolt 7 rotates circumferentially with the annular guide rail 4. When the tail end of the adjusting bolt 7 is obstructed by a push rod extended from a push rod motor 8, the nut corresponding to the adjusting bolt 7 moves forward or backward along the axis of the adjusting bolt 7, causing the sanding belt support plate 2 to deflect counterclockwise or clockwise around the central axis of the rotating shaft 3 to adjust the contact angle between the sanding belt 1 and the cable joint.

[0049] In one specific embodiment, such as Figure 2 As shown, the annular guide rail 4 and at least one guide wheel are arranged on the vertical plate. The guide wheel and the annular guide rail 4 are in close cooperation. Specifically, the first motor 5 drives the guide wheel to rotate, and the guide wheel drives the annular guide rail 4 to rotate using friction, thereby realizing circumferential rotational feed motion. The first motor 5 can change the rotation direction of the guide wheel, thereby changing the circumferential rotation direction of the annular guide rail 4. That is, the annular guide rail 4 rotates clockwise or counterclockwise under the drive of the first motor 5. It is worth noting that the clockwise or counterclockwise direction, forward or backward direction mentioned in this application are relative to the executing subject and are not consistent. At the same time, these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the clockwise direction can also be regarded as the counterclockwise direction, and similarly, forward movement can also be regarded as backward movement. Figure 2 In the middle, the sanding belt support plate 2 is connected to the rotary shaft 3. Figure 1 The rotating shaft and annular guide rail 4 are connected in conjunction, and the sanding belt support plate 2 can then rotate around... Figure 2 The degree of freedom of the rotation of the central rotating shaft 3. Through this degree of freedom of rotation, the angle between the sand belt support plate 2 and the axis of the cable 6 can be dynamically adjusted, thereby ensuring the geometric shape requirements of the reactive force cone.

[0050] In one specific embodiment, the first motor 5 is adapted to drive the annular guide rail 4 to rotate circumferentially in a counterclockwise or clockwise direction. When the tail end of the adjusting bolt 7 is obstructed by the push rod extended from the push rod motor 8, the nut corresponding to the adjusting bolt 7 moves backward or forward along the axis of the adjusting bolt 7, causing the sanding belt support plate 2 to deflect clockwise or counterclockwise around the central axis of the rotating shaft 3 to adjust the contact angle between the sanding belt 1 and the cable connector. Figure 2 For example, the tail end of the adjusting bolt 7 is a specially made cross shape, but it can also be other shapes. When the annular guide rail 4 is driven by the first motor 5 to rotate counterclockwise, the sanding belt support plate 2 and the adjusting bolt 7 also rotate counterclockwise. At this time, if the push rod motor 8 does not extend its push rod, the adjusting bolt 7 will rotate normally in a movable connection. However, when the push rod motor extends its push rod, the rotation of the tail end of the adjusting bolt 7 is hindered, and the corresponding nut is driven to move linearly along the axis of the adjusting bolt 7, which is equivalent to the nut moving forward a certain lead. Therefore, the sanding belt support plate, which is movably hinged to the nut, is moved forward... Figure 2The inner side deflects at a certain angle. After a certain plane angle is formed between the sanding belt support plate 2 and the annular guide rail 4, the push rod motor 8 retracts the push rod, and the adjusting bolt 7 continues to rotate circumferentially with the annular guide rail 4. Meanwhile, the sanding belt support plate 2 maintains the plane angle with the plane where the annular guide rail 4 is located and continues to rotate circumferentially. The sanding belt on the sanding belt support plate 2 can then sand the cable 6 connector at a certain angle. The linear motion of the special nut, through the hinge, causes the sanding belt support plate to rotate around the rotation axis at a certain angle, thereby realizing the adjustment of the angle between the sanding belt and the cable axis, and finally realizing the reaction force cone angle forming motion.

[0051] In one specific embodiment, the abrasive belt 1 is installed on the abrasive belt support plate 2. The appropriate grit of the abrasive belt can be selected to abrade the cable 6 connector as needed. For coarse grinding, a larger grit abrasive belt is used; for fine polishing, a smaller grit abrasive belt is used. Simultaneously, the abrasive belt's grinding speed can be controlled by adjusting the power of the first motor 5.

[0052] In another specific embodiment, see Figures 4-5 , Figure 4 The abrasive belts 1 installed on the abrasive belt support plate 2 include coarse abrasive belts 1-1 and fine polishing abrasive belts 1-2, such as... Figure 5 As shown, the coarse abrasive belt 1-1 and the fine abrasive belt 1-2 are symmetrically installed on the abrasive belt support plate 2. The contact angle between the coarse abrasive belt 1-1 or the fine abrasive belt 1-2 and the cable joint is controlled by the adjusting bolt 7. The grit size of the coarse abrasive belt 1-1 is larger than that of the fine abrasive belt 1-2. Figure 4 For example, Figure 4 Two independently powered belt grinding devices are installed on the belt support plate, with hub motors as the power source. The two grinding devices use belts with different grit sizes. The larger grit belt is mainly used for rough grinding of the reaction cone belt to ensure the required shape. After rough grinding, the smaller grit belt is used to polish the reaction cone belt to ensure the surface quality requirements of the square stress cone. In another specific embodiment, the grinding belt 1 includes belts of various grit sizes to meet the forming requirements of different cable joint reaction cones.

[0053] In one specific embodiment, the device further includes: the annular guide rail 4 is adapted to rotate clockwise under the drive of the first motor 5, and drive the coarse grinding belt 1-1 to rotate circumferentially and coarsely grind around the cable 6 connector; the annular guide rail 4 is also adapted to rotate counterclockwise under the drive of the first motor 5, and drive the fine polishing belt 1-2 to rotate circumferentially and finely polish around the cable 6 connector. With the above-described device, during the initial preparation of the cable joint reaction cone, the first motor 5 drives the annular guide rail 4 to rotate clockwise. When the adjusting bolt 7 is obstructed by the push rod extended from the push rod motor 8, the corresponding nut moves forward, causing the sanding belt support plate 2 to deflect around the axis of the rotary shaft 3 towards the coarse grinding belt 1-1. The coarse grinding belt 1-1 then rotates and coarsely grinds the cable joint 6 at a certain angle. After coarse grinding, the first motor 5 can be controlled to drive the annular guide rail 4 to rotate counterclockwise. When the adjusting bolt 7 is obstructed by the push rod extended from the push rod motor 8, the corresponding nut moves backward, gradually bringing the sanding belt support plate 2 back to the same plane as the annular guide rail 4. It continues to move backward until the sanding belt support plate 2 gradually deflects around the axis of the rotary shaft 3 towards the fine polishing belt 1-2. The fine polishing belt 1-2 then rotates and finely polishes the cable joint 6 at a certain angle. In another specific embodiment, the first motor 5 drives the annular guide rail to rotate in a constant direction, and fine grinding of the cable 6 connector is achieved by changing the sanding belt or manually rotating the sanding belt support plate.

[0054] In one specific embodiment, the device further includes a second motor 9, which drives the abrasive belt 1 to rotate. The rotation of the abrasive belt allows the entire surface of the belt to rotate simultaneously with the cable joint, achieving uniform grinding of the cable joint surface and preventing localized or excessive wear. This improves grinding efficiency. Because the abrasive belt surface rotates continuously, the contact area between the abrasive and the cable joint surface changes, preventing uneven results caused by prolonged grinding in the same position. This allows for faster and more effective removal of unevenness or dirt from the cable joint surface, improving the grinding effect. During grinding, the rotating abrasive belt reduces friction and wear between the belt surface and the cable joint surface, extending the belt's lifespan. Simultaneously, the rotating belt helps to evenly distribute the heat generated during grinding, preventing excessively high local temperatures from damaging the cable joint. This also improves grinding quality and consistency, ensuring the surface quality of the cable joint meets requirements.

[0055] This application provides a method for adjusting the angle of the reaction cone of a cable joint. The cable joint reaction cone forming device includes: a grinding belt 1, which is fixed on a grinding belt support plate 2. The grinding belt support plate 2 is mounted on an annular guide rail 4 via a rotating shaft 3. The initial positions of the grinding belt support plate 2 and the annular guide rail 4 are on the same plane. The annular guide rail 4 rotates circumferentially in a clockwise or counterclockwise direction under the drive of a first motor 5, thereby driving the grinding belt 1 to rotate circumferentially and grind the cable joint 6. Adjusting bolt 7, the front end of which is movably hinged to the annular guide rail 4, and the corresponding nut is movably hinged to the sanding belt support plate 2. The adjusting bolt 7 rotates circumferentially with the annular guide rail 4. When the tail end of the adjusting bolt 7 is obstructed by the push rod extended from the push rod motor 8, the nut corresponding to the adjusting bolt 7 moves forward or backward along the axis of the adjusting bolt 7, and drives the sanding belt support plate 2 to deflect counterclockwise or clockwise around the central axis of the rotary shaft 3 to adjust the contact angle between the sanding belt 1 and the cable connector.

[0056] Figure 6 This is a flowchart illustrating a method for adjusting the angle of the reactive force cone of a cable joint, as shown in a specific exemplary embodiment of this application. The method specifically includes:

[0057] Step S601: Calculate the deflection angle of the sand belt support plate 2 around the central axis of the rotary shaft 3 according to the required angle of the reactive force cone of the cable joint.

[0058] Step S602: Based on the deflection angle calculation result, determine the length by which the adjusting nut corresponding to the adjusting bolt 7 moves forward or backward along the axis of the adjusting bolt 7.

[0059] Step S603: Determine the frequency at which the push rod motor 8 extends the push rod to obstruct the rotation of the tail end of the adjusting bolt 7 based on the length by which the adjusting nut corresponding to the adjusting bolt 7 moves forward or backward along the axis of the adjusting bolt 7.

[0060] In one specific embodiment, a cable connector with a reaction cone angle of θ needs to be manufactured. The deflection angle of the sanding belt support plate 2 around the central axis of the rotating shaft 3 is θ. The length dx of the adjusting nut corresponding to the adjusting bolt 7 moving forward or backward along the axis of the adjusting bolt 7 is calculated using the following formula:

[0061]

[0062] Wherein, R is the rotation radius (mm) of the sand belt support plate 2.

[0063] The frequency n at which the push rod motor 8 extends out of the push rod and obstructs the rotation of the tail end of the adjusting bolt 7 is calculated using the following formula:

[0064]

[0065] Wherein, P is the pitch of the adjusting bolt 7.

[0066] In one specific embodiment, the reaction force taper of the standard cable connector is 5.65°. Therefore, the sanding belt support plate 2 needs to deflect θ = 5.65°. If the rotation radius of the sanding belt support plate 2 is R = 99.3 mm, then the length dx of the nut corresponding to the adjusting bolt 7 moving forward or backward along the axis of the adjusting bolt 7 is approximately 9.8 mm. The frequency n = 39 is when the push rod motor 8 extends its push rod to obstruct the rotation of the tail end of the adjusting bolt 7. This frequency refers to the n circumferential rotations of the annular guide rail 4. The push rod motor 8 extends its push rod to obstruct the adjusting bolt 7, causing the sanding belt support plate 2 to gradually deflect until the deflection angle reaches 5.65°. At this deflection angle, the sanding belt 2 can sand a cable connector with the corresponding reaction force taper.

[0067] In another specific embodiment, the duration for which the push rod motor 8 extends the push rod is determined based on the rotational speed of the annular guide rail 4. This method allows for the calculation of the duration and timing of the push rod motor 8 extending the push rod at different reaction force cone angles, enabling the design of a complete grinding process for automated operation and reducing labor intensity.

[0068] In one specific embodiment, the first motor 5 in the device is adapted to drive the annular guide rail 4 to rotate circumferentially in a counterclockwise or clockwise direction. When the tail end of the adjusting bolt 7 is obstructed by the push rod extended from the push rod motor 8, the nut corresponding to the adjusting bolt 7 moves backward or forward along the axis of the adjusting bolt 7, causing the sanding belt support plate 2 to deflect clockwise or counterclockwise around the central axis of the rotating shaft 3 to adjust the contact angle between the sanding belt 1 and the cable connector. The method includes: when the calculation result of the deflection angle indicates that the sanding belt support plate 2 needs to return to the initial position or change the deflection direction of the sanding belt support plate 2 around the central axis of the rotating shaft 3, controlling the first motor 5 to change the circumferential rotation direction of the annular guide rail 4.

[0069] In another specific embodiment, the abrasive belt 1 in the device includes a coarse abrasive belt 1-1 and a fine abrasive belt 1-2. The coarse abrasive belt 1-1 and the fine abrasive belt 1-2 are symmetrically installed on the abrasive belt support plate 2. The contact angle between the coarse abrasive belt 1-1 or the fine abrasive belt 1-2 and the cable joint is controlled by the adjusting bolt 7. The coarse abrasive belt 1-1 has a larger particle size than the fine abrasive belt 1-2. The method further includes: selecting the coarse abrasive belt 1-1 or the fine abrasive belt 1-2 to abrade the cable joint according to the required reaction cone angle of the cable joint; when the coarse abrasive belt 1-1 is selected to abrade the cable joint, controlling the abrasive belt support plate 2 to deflect around the central axis of the rotary shaft 3 in the direction of the coarse abrasive belt 1-1; when the fine abrasive belt 1-2 is selected to abrade the cable joint, controlling the abrasive belt support plate 2 to deflect around the central axis of the rotary shaft 3 in the direction of the fine abrasive belt 1-2.

[0070] In another specific embodiment, the annular guide rail 4 in the device is adapted to rotate clockwise under the drive of the first motor 5, and drive the coarse abrasive belt 1-1 to rotate circumferentially and perform coarse grinding around the cable 6 connector; the annular guide rail 4 is also adapted to rotate counterclockwise under the drive of the first motor 5, and drive the fine polishing belt 1-2 to rotate circumferentially and perform fine polishing around the cable 6 connector; the method further includes: when the coarse abrasive belt 1-1 is selected to grind the cable connector, controlling the first motor 5 to drive the annular guide rail 4 to rotate clockwise, and drive the coarse abrasive belt 1-1 to rotate circumferentially and perform coarse grinding around the cable 6 connector; when the fine polishing belt 1-2 is selected to grind the cable connector, controlling the first motor 5 to drive the annular guide rail 4 to rotate counterclockwise, and drive the fine polishing belt 1-2 to rotate circumferentially and perform fine polishing around the cable 6 connector.
