Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a semi-conical resin block. Background Technology

[0002] Cables are a crucial component of power plants and substations, and resin blocks are key auxiliary components in cable laying. Typically made from high-molecular-weight resin through injection molding, compression molding, or curing, the combination of the resin block's material properties and structural design enables reliable cable fixation, protection, and management. Resin blocks are widely used in various electrical and communication scenarios, ensuring the long-term stable operation of electrical systems. However, in practical applications, due to the wedge-shaped structure of the resin block, relative rotation and displacement may occur between the fixing cylinder and the cable, limiting the protective effect on the cable during use. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a semi-conical resin block, which aims to improve the problem that existing resin blocks have poor cable fixing effect and limited protection effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a semi-conical resin block, comprising:

[0005] A cable, wherein a fixing cylinder is fitted on the surface of the cable, and a split resin block is provided between the cable and the fixing cylinder, and a connection hole is provided on the surface of the split resin block;

[0006] A connecting mechanism, comprising a connecting column, which engages with the inner wall of a connecting hole, and a first connecting member and a second connecting member are fixedly connected to the front side of the connecting column, with through holes provided on the surfaces of both the first and second connecting members.

[0007] Through the above technical solution, when the cable experiences sudden vibration, the connection mechanism can convert the impact energy into the elastic potential energy of the material through the triangular layout of the connection holes and the connectors connected by studs, thereby strengthening the protection of the cable.

[0008] As a further description of the above technical solution: the split resin block includes a semi-conical resin block one and a semi-conical resin block two. The surfaces of the semi-conical resin block one and the semi-conical resin block two are provided with guide curved surfaces and arc-shaped grooves, and the arc-shaped grooves are in contact with the outer wall surface of the cable.

[0009] The above technical solution allows for the separate installation of resin blocks from both ends of the cable, making the resin blocks suitable for cables of any length.

[0010] As a further description of the above technical solution: the split resin block also includes a semi-pyramidal resin block one and a semi-pyramidal resin block two, and the surfaces of the semi-pyramidal resin block one and the semi-pyramidal resin block two are provided with guide slopes.

[0011] The above technical solution, with its smoothed guide slope, effectively avoids jamming caused by angular deviation during insertion, thus improving the smoothness of component installation.

[0012] As a further description of the above technical solution: the connecting hole is located on the front side of the first semi-pyramidal resin block, the second semi-pyramidal resin block, the first semi-conical resin block, and the second semi-conical resin block.

[0013] The above technical solution allows for the quick loading of connecting mechanisms into the split resin blocks by opening connecting holes on both the surface of the semi-pyramidal resin block and the semi-conical resin block, thus improving the ease of use of the split resin blocks.

[0014] As a further description of the above technical solution: both the first semi-conical resin block and the second semi-conical resin block are provided with a first bonding surface, and the first bonding surface is bonded to the inner wall surface of the fixed cylinder.

[0015] The above technical solution allows for a tight fit between the semi-conical resin block and the inner wall of the fixing cylinder by setting a first bonding surface on the surface of the semi-conical resin block, thereby increasing the contact area and reducing the risk of damage to the cable sheath.

[0016] As a further description of the above technical solution: both the first and second semi-pyramidal resin blocks are provided with guide slopes and second bonding surfaces, and the second bonding surfaces are bonded to the inner wall surface of the fixed cylinder.

[0017] Through the above technical solution, when the cable is subjected to radial load, the second bonding surface can evenly distribute the concentrated stress to the entire resin block, avoiding material fatigue or deformation caused by excessive local stress.

[0018] As a further description of the above technical solution: the inner wall of the through hole is threaded with a double-ended stud, and nuts are threaded on both sides of the double-ended stud. The double-ended stud is used to connect the first connector and the second connector.

[0019] The above technical solution, which connects the first and second connectors with double-ended studs, enables the connection mechanism to maintain stable preload even under vibration, effectively preventing loosening of the connection.

[0020] As a further description of the above technical solution: the horizontal projection length of the arc groove is set to 35-40mm, and the diameter of the front side of the semi-conical resin block is set to 80-85mm.

[0021] The above technical solution provides an adjustment margin for adapting to different cable specifications by standardizing the resin block specifications. It allows for the selection of the optimal contact length based on the actual cable outer diameter within the specification range, thereby improving the compatibility of the resin block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a split resin block with a connecting hole is inserted into the fixed cylinder. The first connector is connected to the left resin block, and the second connector is connected to the right resin block. The first connector and the second connector are connected together by inserting a stud into the through hole, thereby enhancing the fixing and protection effect of the resin block on the cable.

[0024] 2. In this utility model, the split resin blocks can be installed from both ends of the cable, which not only provides auxiliary support for the cable, but also makes it easier to install and disassemble repeatedly. It is applicable to cables of any length. By adjusting the bottom diameter and center hole diameter of the resin block, it can be compatible with various cable specifications and has strong versatility. Attached Figure Description

[0032] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Reference Figures 3-4 One embodiment of this utility model provides: a semi-conical resin block, comprising:

[0034] Cable 1, a fixing cylinder 2 is fitted on the surface of cable 1, a split resin block 3 is provided between cable 1 and fixing cylinder 2, and a connection hole 4 is opened on the surface of the split resin block 3.

[0035] The connecting mechanism 5 includes a connecting post 503, which engages with the inner wall of the connecting hole 4. A first connecting member 501 and a second connecting member 502 are fixedly connected to the front side of the connecting post 503. Both the first connecting member 501 and the second connecting member 502 have through holes 504 on their surfaces.

[0036] Specifically, the first connector 501 and the second connector 502 fixed on the front side of the connecting post 503 are symmetrically distributed and respectively connect to the adjacent split resin blocks 3. The through holes 504 on the surfaces of the two provide a through channel for the connection medium. When the double-ended stud passes through the through hole 504 and is tightened by the nuts at both ends, the separated split resin blocks 3 can form a rigid connection system on the inner wall of the fixing cylinder 2, so that the resin blocks can provide multi-point coordinated force support for the cable 1, effectively improving the shear resistance and structural stability of the fixing system. At the same time, the connecting mechanism 5 utilizes the adjustability of the threaded connection between the double-ended stud and the connector to adapt to the combination requirements of resin blocks of different thicknesses or installation gaps.

[0037] Reference Figures 1-2The split resin block 3 includes a semi-conical resin block 1 301 and a semi-conical resin block 2 302. The surfaces of the semi-conical resin block 1 301 and the semi-conical resin block 2 302 are provided with a guide curved surface 303 and an arc groove 305. The arc groove 305 is in contact with the outer wall surface of the cable 1.

[0038] Specifically, the split resin blocks 3 are symmetrically distributed on the inner wall of the fixed cylinder 2. The surface of the split resin blocks 3 and the inner wall of the fixed cylinder 2 form a planar bonding structure to ensure the stability of the resin blocks inside the cylinder. The inner wall of the split resin blocks 3 limits the cable 1 to the central axis position of the fixed cylinder 2 by means of curved surface bonding. At the same time, by also setting the split resin blocks 3 at the end of the cable 1, a support layout for the front and rear ends of the cable 1 is formed, which effectively avoids the radial offset or axial movement of the cable 1 inside the fixed cylinder 2, and provides a mechanical support foundation for the stable installation of the cable 1.

[0039] Reference Figure 5 The split resin block 3 also includes a semi-pyramidal resin block 1 311 and a semi-pyramidal resin block 2 312, and the surfaces of the semi-pyramidal resin block 1 311 and the semi-pyramidal resin block 2 312 are provided with guide slopes 313.

[0040] Specifically, the semi-pyramidal resin block 311 and the semi-pyramidal resin block 312 adopt a pyramidal structure design, and their sides form a three-point contact fit with the inner wall of the fixing cylinder 2. Compared with the semi-conical resin block 301 and the semi-conical resin block 302, they can provide more stable circumferential constraints, thereby effectively resisting the radial force of the cable 1.

[0041] Reference Figures 3-4 The connecting hole 4 is located on the front side of the semi-pyramidal resin block 311, the semi-pyramidal resin block 312, the semi-conical resin block 301, and the semi-conical resin block 302.

[0042] Specifically, the connecting holes 4 are arranged in a triangular pattern. The top connecting hole 4 and the bottom connecting hole 4 are located on the same vertical line. The connecting holes 4 are located to the left of the top and bottom connecting holes 4. The three connecting points form an asymmetrical triangular structure, which can effectively resist the vibration and torsional torque of the cable 1 in the horizontal direction. The connecting mechanism 5 forms a sliding fit structure with the inner wall of the connecting hole 4, so as to realize the quick installation of the connecting mechanism 5 on the resin block.

[0043] Reference Figure 2 Both the first semi-conical resin block 301 and the second semi-conical resin block 302 have a first bonding surface 304 on their surfaces, and the first bonding surface 304 is bonded to the inner wall surface of the fixed cylinder 2.

[0044] Specifically, the arc grooves 305 on the surfaces of the first semi-conical resin block 301 and the second semi-conical resin block 302 are semi-circular and fit against the surface of the cable 1. The guide surface 303 adopts a gradually expanding curved surface structure, and its radius of curvature gradually increases from the end of the resin block towards the first contact surface 304, forming a transition area with a guiding function. When the resin block is inserted into the fixing cylinder 2, the guide surface 303 and the first contact surface 304 can help correct the insertion angle of the resin block, reduce manual alignment operations, and reduce assembly difficulty.

[0045] Reference Figure 5 Both the surface of the first semi-pyramidal resin block 311 and the second semi-pyramidal resin block 312 are provided with a guide slope 313 and a second bonding surface 314, and the second bonding surface 314 is bonded to the inner wall surface of the fixed cylinder 2.

[0046] Specifically, the second mating surface 314 is set as an arc surface, which can avoid wear on the inner wall when the semi-pyramidal resin block is inserted into the fixed cylinder 2. At the same time, the surfaces of the first semi-pyramidal resin block 311 and the second semi-pyramidal resin block 312 are provided with connecting holes 4, which can be used to install the connecting mechanism 5, thereby helping to strengthen the fixation of the first semi-pyramidal resin block 311 and the second semi-pyramidal resin block 312.

[0047] Reference Figure 4 The inner wall of the through hole 504 is threaded with a double-ended stud, and nuts are threaded on both sides of the double-ended stud. The double-ended stud is used to connect the first connector 501 and the second connector 502.

[0048] Specifically, the threaded structure on the inner wall of the through hole 504 and the external thread of the double-ended stud form a standard threaded pair. Force conversion and transmission are achieved through the thread. When the nut is tightened axially along the double-ended stud, the axial preload generated by the threaded pair makes the first connecting piece 501 and the second connecting piece 502 fit tightly together, forming a rigid connection interface. At the same time, by adjusting the screw depth of the nut, the magnitude of the preload can be precisely controlled to adapt to the fastening requirements under different working conditions.

[0049] Reference Figures 1-2 The horizontal projection length of the arc groove 305 is set to 35mm, and the front diameter of the semi-conical resin block 301 is set to 80mm.

[0050] Specifically, the split resin block 3 is integrally molded using 3D printing technology, avoiding the time-consuming, labor-intensive, and material-wasting process caused by traditional mechanical grinding. The arc groove 305 controls the radial displacement of the cable 1 through the axial contact length, and the diameter of the front side of the resin block ensures the circumferential positioning of the resin block within the cylinder. When both parameters are within the set range, the resin block can form a stable three-point contact with the support area of ​​the cable 1, effectively suppressing the swaying and rotation of the cable 1.

[0051] Working principle: The main structure of the semi-conical resin block 301 and the semi-conical resin block 302 is a semi-conical resin block composed of a 100mm circle, a cone with a height of 32.31mm, and a cylinder with a diameter of 36.06mm and a height of 32.32mm after the center and base are subtracted. The guide surface 303 is a gradually expanding surface. After the fixing cylinder 2 is sleeved on the surface of the cable 1, the resin block is pushed into the fixing cylinder 2 by facing the guide surface 303 towards the fixing cylinder 2. At this time, the first contact surface 304 is in contact with the inner wall of the fixing cylinder 2, and the arc groove 305 is in contact with the outer wall of the cable 1, thereby realizing the auxiliary support of the cable 1 and fixing the cable 1 in the center of the fixing cylinder 2. In addition, the split resin block 3 can also be other shapes to achieve different effects, such as reducing the radial force generated by the cable 1 by using the semi-conical resin block 311 and the semi-conical resin block 312.

[0052] To further ensure the stability of the cable 1, the connecting mechanism 5 is installed on the inner wall of the connecting hole 4. The connecting mechanism 5 is divided into two parts, left and right. The first connecting piece 501 on the left is connected to the semi-conical resin block 301 or the semi-pyramidal resin block 311, and the second connecting piece 502 on the right is connected to the semi-conical resin block 302 or the semi-pyramidal resin block 312. Since the first connecting piece 501 and the second connecting piece 502 are provided with through holes 504 at both the upper and lower ends, the first connecting piece 501 and the second connecting piece 502 are connected together by inserting a stud into the through hole 504, thereby strengthening the fixation of the cable 1 by the split resin block 3.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
