Description

Technical Field

[0001] The invention relates to the technical field of wire clamps, in particular to a wire clamp used in a ring network cabinet. Background Art

[0002] The wire clamp connection technology is a technology used for wire connection. The hook-type conductive clamp is a conductive part with a conductive part in the shape of a hook clamp. The existing patent is a wire clamp used in the ring network cabinet. The patent publication number CN221767290U includes a wire clamp fixing plate, a side clamp plate and an upper limit plate. The wire clamp fixing plate is provided with side clamp plates on both sides, and the upper limit plate slides horizontally on the top of the side clamp plate. A middle partition is fixed in the middle of the wire clamp fixing plate, and an upper roller rotates on the top of the middle partition. The upper arc-shaped clamping strip slides on the top of the middle partition. The head end of the wire clamp fixing plate is provided with a middle screw, and side rollers rotate on both sides of the middle screw. The side connection screw and the middle screw are screwed together for axial movement, and the spacing between the side clamp and the middle partition is expanded or reduced. The space between the side clamp and the middle partition is adjusted according to the number or thickness of the wires. The wire is fixed more firmly, which solves the problem that the width of the wire clamp is fixed. If there are many redundant wires inside the wire clamp, it will lead to a large space for wire movement, which is not conducive to the fixation of the wire.

Excessive friction will not only cause excessive high temperature transfer, but also cause damage to the cables due to excessive friction. Therefore, we propose a wire clamp for use in ring network cabinets to solve the above-mentioned problems. Summary of the invention

The side of the guide rod assembly 3011 away from the wire roller 3012 is fixedly connected with a piston member 3013. The main body of the piston member 3013 is made of rubber. The outer side of the piston member 3013 is fixedly connected with a sealing ring 3014. The sealing ring 3014 and the piston member 3013 together form The sealing structure of the expansion cylinder 2012 is provided. A connecting block 3015 is fixedly connected to the side of the guide rod assembly 3011 away from the line roller 3012. The upper and lower sides of the connecting block 3015 are provided with planes. A spring rod 3016 is fixedly connected to the plane. The main body of the spring rod 3016 is a telescopic rod structure with a spring. A friction assembly 3017 is fixedly connected to the side of the spring rod 3016 away from the connecting block 3015. The friction assembly 3017 contacts the inner wall of the expansion cylinder 2012. The inner side of the expansion cylinder 2012 is filled with compressed gas 3018. The compressed gas 3018 is a heat expansion structure.

[0032] The support seat 1 carries the support assembly 3, and the support assembly 3 uses the bearing seat 301 to install the guide rod assembly 3011 and the wire roller 3012 to guide the cable 2020. The piston member 3013 and the sealing ring 3014 seal the extension cylinder 2012. The spring rod 3016 and the friction assembly 3017 cooperate with each other, and the compressed gas 3018 that expands due to heat in the extension cylinder 2012 is used to guide the cable 2020 and adaptively adjust the state according to the temperature, so as to protect the cable 2020.

[0033] See also Figure 1 , Figure 6 The support base 1 has through grooves arranged in a linear array inside, the through grooves being ventilation grooves 101, and the support base 1 has heat dissipation grooves 1011 arranged on both the front and rear sides inside, the heat dissipation grooves 1011 being connected with the ventilation grooves 101;

[0034] Through the ventilation groove 101 in the support base 1 and the heat dissipation groove 1011 penetrating therewith, air circulation is effectively promoted to dissipate the working heat of the device, avoid high temperature affecting the performance of the cable 2020 and components, and ensure stable operation of the device and extend its service life.

[0035] See also Figure 3 , Figure 7 The support base 1 has a through hole inside, which is a mounting hole 1012. There are four mounting holes 1012 in total, and the four mounting holes 1012 are respectively opened at the four corners inside the support base 1;

[0036] Through the mounting holes 1012 at the four corners of the support base 1, a mounting structure is formed with the support base 1, so that the wire clamp can be firmly installed in the ring network cabinet, providing stable support for the entire device to ensure that it does not move during operation.

[0037] See also Figure 2 , Figure 6 The support seat 1 and the mounting hole 1012 together form a mounting structure, and a transverse groove is provided on the top surface of the support seat 1, and the transverse groove is a guide groove 1013. There are two guide grooves 1013, and the two guide grooves 1013 are respectively provided on the left and right sides of the inside of the support seat 1;

[0038] The support seat 1 and the mounting hole 1012 ensure a stable installation, and the guide groove 1013 on the top surface provides a guide for the sliding of the moving component 201, so as to flexibly adjust the position of the clamped workpiece according to the situation of the cable 2020.

[0039] See also Figure 3 , Figure 8 The inner side of the guide groove 1013 is fixedly connected with a reset component 2, the main body of the reset component 2 is a telescopic rod structure with a spring, and the outer side of the reset component 2 is fixedly connected with a moving component 201, the main body of the moving component 201 is a rectangular block structure;

[0040] By connecting the moving component 201 with the reset component 2 in the guide groove 1013, the telescopic rod structure with a spring enables the moving component 201 to automatically reset after moving, thereby simplifying the installation and adjustment process of the cable 2020.

[0041] See also Figure 1 , Figure 2 There are two moving components 201, and the outer sides of the two moving components 201 are oppositely fixedly connected with two slider components 2011 of the lifting structure, and the moving components 201 are slidably connected in the guide groove 1013 through the slider components 2011;

[0042] By allowing the moving component 201 to slide flexibly in the guide groove 1013 through the slider component 2011 , the position can be quickly adjusted according to the actual condition of the cable 2020 , thereby enhancing the adaptability of the device to different cables 2020 .

[0043] See also Figure 4 , Figure 8 The top of the moving component 201 is provided with an arc-shaped groove, the interior of which is fixedly connected with an expansion tube 2012, the outer side of the expansion tube 2012 is fixedly connected with a bracket 2013, and the main body of the bracket 2013 is an L-shaped structure;

[0044] By means of the expansion tube 2012 at the top of the mobile component 201 and the bracket 2013 on the outside, an installation foundation is provided for the subsequent cable 2020 clamping structure, which is conducive to building a stable cable 2020 clamping system.

[0045] See also Figure 3 , Figure 7 There are two brackets 2013, and the inner sides of the two brackets 2013 are fixedly connected with clamping parts 2014, and the inner walls of the clamping parts 2014 are provided with arc grooves;

[0046] The arc-shaped groove on the inner wall of the clamping portion 2014 on the inner side of the bracket 2013 can initially limit the cable 2020 so that the cable 2020 can maintain a relatively stable position in the wire clamp.

[0047] See also Figure 1 , Figure 2 The bracket 2013 and the clamping part 2014 together form a clamping and limiting structure, and the inside of the arc-shaped groove opened on the inner wall of the clamping part 2014 is fixedly connected with a flexible pad 2015;

[0048] By forming a clamping limit structure between the bracket 2013 and the clamping portion 2014 and cooperating with the flexible pad 2015, the clamping force is buffered to avoid damaging the cable 2020 and at the same time enhance the clamping firmness.

[0049] See also Figure 5 , Figure 8 The flexible pad 2015 is made of rubber, and a cable 2020 is clamped and limited inside the flexible pad 2015. A guide column 2016 of a cylindrical structure is fixedly connected to the top surface of the clamping portion 2014. A collar assembly 2017 is sleeved on the outside of the guide column 216. A connector 2018 is fixedly connected to the inside of the collar assembly 2017, and a hanging ring assembly 2019 is fixedly connected to the top of the connector 2018.

[0050] The cable 2020 is clamped by the flexible pad 2015, and the guide column 2016, the ring assembly 2017, the connector 2018 and the hanging ring assembly 2019 at the top of the clamping part 2014 provide more fixing methods for the cable 2020, further improving the stability and safety of the cable 2020 in the wire clamp.

[0051] When working, first, through the mounting holes 1012 at the four corners of the support base 1, use appropriate mounting parts (such as bolts, etc.) to install the entire wire clamp at a suitable position in the ring network cabinet, ensure that the support base 1 is installed firmly, place the cable 2020 to be installed in a suitable position, and prepare for the clamping operation;

[0052] The support assembly 3 is fixed on the left and right sides of the top surface of the support seat 1, and the bearing seat 301 inside thereof is installed with the guide rod assembly 3011. The wire roller 3012 inside the guide rod assembly 3011 is used to guide the cable 2020. When the cable 2020 passes through the wire clamp, the wire roller 3012 can reduce the friction between the cable 2020 and other components, so that the cable 2020 can pass through the wire clamp smoothly, avoiding the cable 2020 from being damaged by excessive resistance during the introduction process;

[0053] The side of the guide rod assembly 3011 away from the wire roller 3012 is connected to the piston 3013 and the sealing ring 3014, which seal the expansion cylinder 2012 together. The expansion cylinder 2012 is filled with compressed gas 3018 that expands due to heat. As the operator increases the speed of pulling the cable 2020, the wire roller 3012 will drive the friction assembly 3017 to rotate, and rub against the inner wall of the expansion cylinder 2012 to generate high temperature. The compressed gas 3018 will expand the piston 3013 accordingly to drive the guide rod assembly 3011 to move, and the position of the wire roller 3012 on the guide rod assembly 3011 will also change accordingly, thereby fine-tuning the position of the clamping part 2014, so that the cable 2020 is always kept in a suitable position, reducing the friction of the cable 2020;

[0054] The moving component 201 slides in the guide groove 1013 through the slider component 2011. The reset component 2 inside the guide groove 1013 can automatically reset the moving component 201 after it moves. When the clamping position of the cable 2020 needs to be adjusted, the moving component 201 can be manually moved. After reaching the appropriate position, the moving component 201 is released, and the reset component 2 will automatically reset it to ensure the stability of the clamping. The expansion cylinder 2012 at the top of the moving component 201 and the L-shaped bracket 2013 on the outside provide an installation basis for the clamping part 2014. The clamping part 2014 on the inside of the two brackets 2013 performs preliminary positioning of the cable 2020 through the arc groove of the inner wall. The bracket 2013 and the clamping part 2014 form a clamping limiting structure. The flexible pad 2015 in the arc groove of the clamping part 2014 can buffer the clamping force to avoid damaging the cable 2020 and enhance the firmness of the clamping.

[0055] The guide post 2016, the collar assembly 2017, the connector 2018 and the hanging ring assembly 2019 at the top of the clamping part 2014 provide an additional fixing method for the cable 2020. The hanging ring assembly 2019 can be used to connect the cable 2020 to other fixed structures in the ring network cabinet, further enhancing the stability of the cable 2020 in the wire clamp, ensuring that the cable 2020 can remain fixed even in a complex working environment;

[0056] The air permeable groove 101 inside the support base 1 and the heat dissipation groove 1011 passing therethrough can promote air circulation. During the operation of the wire clamp, the heat generated by the cable 2020 passing through and the heat generated by other components can be dissipated through the air permeable groove 101 and the heat dissipation groove 1011, thereby avoiding heat accumulation from damaging the cable 2020 and other components and ensuring stable operation of the device.

[0057] In summary, the device can reduce excessive squeezing after clamping by providing the flexible pad 2015.
