[0026] Cable terminals are generally installed on the roofs of rail transit, subways and other vehicles to fix the cables and connect the circuits.

[0027] The cable seat terminal in the related technology is usually a split assembly structure. Especially when the stress cone is installed, it usually includes components such as a cone support, a spring and a spring pressure plate. The stress cone is fixed by installing these components. This assembly method has many parts and the assembly process is cumbersome. In addition, it is easy to produce interface air gaps and impurities during the installation process, which increases the safety risk.

[0028] In view of the problems in the related technology, the following Figure 1 The utility model describes an integrated cable seat terminal, which includes a main body 10, a base 20 and a stress cone 40; the main body 10 has a cable through hole 11, which passes through the main body 10 in the axial direction; the base 20 is provided at one end of the main body 10, and the other end of the main body 10 is provided with an insert 30; the stress cone 40 is provided in the cable through hole 11 and is arranged close to the base 20; wherein the main body 10, the base 20, the insert 30 and the stress cone 40 are integrally formed. The cable seat terminal is used to connect the cable 100 to the connector position of the device or other cables 100. When connecting, the cable seat terminal needs to be installed in the designated position to achieve installation. In this embodiment, the integral molding of the main body 10, the base 20, the insert 30 and the stress cone 40 makes the whole convenient for installation, and the safety risks caused by assembly are avoided by the integral setting.

[0029] It will be appreciated that the cable 100 is secured within the cable through-hole 11 and connected to other devices or cables 100 via the insert 30. In this embodiment, the integrated design reduces the number of components and enhances overall structural strength, avoiding air gaps created during assembly and other installation risks associated with debris. During installation, the cable pedestal terminal is installed directly through the connection between the base 20 and other components or devices, improving installation efficiency and quality.

[0030] In a specific configuration, the cable through hole 11 is a vertical straight hole, and the cable 100 passes through the cable through hole 11 and is fixed by the cable through hole 11 .

[0031] According to one embodiment of the present invention, the main body 10 is constructed as a columnar structure, and the outer diameter of the lower portion of the main body 10 is larger than the outer diameter of the upper portion of the main body 10. In this embodiment, by designing the size of the lower portion of the main body 10 to be larger than the size of the upper portion, the overall structure of the main body 10 is better able to withstand stress and has higher structural strength.

[0032] In the specific setting, there is a smooth variable diameter area between the lower part of the main body 10 and the upper part of the main body 10, that is, the outer diameter of the area segment extending from the lower part of the main body 10 toward the upper part of the main body 10 in the vertical direction gradually decreases, which can reduce the stress of the main body 10, so that the overall force strength of the main body 10 is higher, and a stable connection of the cable 100 is achieved.

[0033] The main body 10 of the columnar structure makes the overall structural strength of the cable seat terminal higher and has higher connection strength, thereby achieving high-strength connection of the cable 100 and ensuring the stability of the cable seat terminal.

[0034] In a specific configuration, an shed 12 is formed on the outer wall of the main body 10. The shed 12 is integrally formed on the outer wall of the main body 10 and provides an additional insulation layer, thereby increasing the electric field control capability and insulation strength of the cable terminal. It can also reduce damage and wear of the cable 100 caused by external physical effects, thereby improving protection for the cable 100 and extending its service life.

[0035] In a specific embodiment, the shed 12 includes a plurality of flanges arranged at intervals, and the flanges have two sizes, one flange having a larger outer protrusion and the other flange having a smaller outer protrusion. The larger flanges and the smaller flanges are alternately arranged to form the shed 12. This arrangement gives the shed 12 a higher structural strength, enabling it to achieve more effective protection and extend the service life of the cable seat terminal.

[0036] According to the embodiment provided by the present invention, the end of the cable through-hole 11 near the base 20 has a sealing countersunk hole 13 for installing the sealing plug 50. The aperture of the sealing countersunk hole 13 is larger than the aperture of the cable through-hole 11. After the cable 100 is inserted into the cable through-hole 11, the gap between the cable 100 and the cable through-hole 11 needs to be sealed to improve the quality of cable installation. In this embodiment, the sealing plug 50 is installed by forming the sealing countersunk hole 13 in the section of the main body 10, which improves the convenience of installation of the sealing plug 50 and enables quick assembly of the sealing plug 50.

[0037] During installation, the cable 100 is passed through the cable through-hole 11. After the cable 100 is inserted, the sealing plug 50 is inserted to seal the cable 100. It is understood that the sealing plug 50 can be pre-installed on the cable 100 before installation. After the cable 100 is assembled, the sealing plug 50 is inserted into the sealing counterbore 13 to complete the installation. The entire installation process is simple and facilitates quick assembly.

[0038] According to the embodiment provided by the present invention, a mounting countersunk hole 14 is formed at one end of the cable through-hole 11 near the insert 30. The diameter of the mounting countersunk hole 14 is larger than the diameter of the cable through-hole 11, and the insert 30 is disposed within the mounting countersunk hole 14. The placement of the insert 30 within the mounting countersunk hole 14 facilitates connection between the case and the cable 100 connection fittings, achieving an overall high-strength connection.

[0039] During the specific connection, the electrical connection fitting is electrically connected to the cable core 101 of the cable 100. In this embodiment, a part of the main body of the cable 100 fitting 60 is arranged in the installation countersunk hole 14 to make the overall strength higher after the connection, and to have a more stable connection tightness, so that the structural strength of the cable 100 fitting 60 connection is higher and the stability is stronger.

[0040] In the specific setting, the insert 30 is arranged in the mounting countersunk hole 14, and a connecting hole is provided in the middle of the insert 30. The connecting hole is concentrically arranged with the cable through hole 11, and the aperture of the connecting through hole is smaller than the aperture of the cable through hole 11.

[0041] It is understood that the insert 30 is integrally provided with the main body 10, and a bolt hole is provided on the insert 30. One end of the cable core 101 of the cable 100 passes through the connection hole and is connected to the cable 100 hardware 60, thereby achieving the conduction of the cable 100. The aperture of the connection hole is set smaller than the aperture of the cable through hole 11 to limit the position of the cable core 101 and prevent the cable core 101 from shaking in the connection hole if the aperture is too large.

[0042] According to some embodiments provided by the present invention, a portion of the base 20 is located within the main body 10, and another portion of the base 20 is located at the end of the main body 10. The base 20 is provided with a sink 21 for connecting to a clamping plate 22, and fixing screw holes are provided inside the sink 21 and on the outer edge of the sink 21. The main body 10 of the cable 100 (the section with the insulating layer) is located in the base 20, and the main body 10 of the cable 100 is fixed by fixing the base 20. In this embodiment, the provision of the sink 21 facilitates the connection of the clamping plate 22, and the clamping plate 22 can be used to fix the cable 100 after installation, thereby achieving a stable connection of the cable 100 and improving the reliability and stability of the device.

[0043] It is understood that a through hole is provided in the middle of the countersunk platform 21. The diameter of the through hole is larger than the diameter of the sealing countersunk hole 13. This arrangement facilitates the installation of the sealing plug 50, and the pressing plate 22 can be connected through the screw hole to limit the sealing plug 50, thereby achieving a tight connection of the sealing plug 50 and improving the stability and reliability of the cable 100 connection.

[0044] Furthermore, a portion of the base 20 is located within the main body 10 , which increases the connection strength of the base 20 and the main body 10 as a whole, thereby increasing the structural strength and stability of the base 20 .

[0045] In a specific embodiment, the main body 10, insert 30, base 20, and stress cone 40 are made of the same material. That is, during the integral molding process, the insert 30, base 20, and stress cone 40 can be made of the same material as the main body 10, facilitating integral molding. This approach facilitates the molding and configuration of the cable pedestal terminal and reduces its manufacturing cost.

[0046] In specific applications, the main body 10, the insert 30, the base 20 and the stress cone 40 are all made of silicone rubber. The limitation of the silicone rubber material makes the whole have higher strength, is easy to prepare, and can achieve higher strength connection with the cable 100.

[0047] In a specific embodiment of the present invention, the outer wall of the stress cone 40 has a conical structure, and the end of the stress cone 40 near the insert 30 has a flared structure. The conical design of the stress cone 40 helps to evenly distribute the electric field stress. The conical structure allows the electric field lines to be densely concentrated at the top of the cone, thereby reducing the electric field strength at the joint.

[0048] The flared structure of the stress cone 40 effectively combines the entire stress cone 40 with the column, and can improve the strength of the connection structure of the stress cone 40 through the cooperation between the column and the stress cone 40, thereby improving the stability and reliability of the stress cone 40. Figure 1As shown, the aperture of the entire cable through hole 11 remains unchanged, and the excess part of the stress cone 40 is filled with the column part, so that the contact area between the stress cone 40 and the column part is increased, thereby improving the structural strength of the connection of the stress cone 40.

[0049] In a specific configuration, the stress cone 40 includes a stress cone 40 made of a semiconductor material. By limiting the semiconductor material, the stress cone 40 has good electrical conductivity and mechanical strength, can withstand current load and maintain structural stability.

[0050] like Figure 2 As shown, during the installation of the cable seat terminal, the cable 100 is processed, the outer insulation layer of the cable 100 is stripped, and the cable core 101 at one end of the cable 100 is exposed. The compression plate 22 and the sealing plug 50 are then inserted in sequence. The cable seat terminal is then installed so that one end of the cable enters through the cable through-hole 11, and finally the exposed end of the cable core 101 is located in the connection hole. The insulation layer stripping position is located at the stress cone 40 position. The sealing plug 50 and the compression plate 22 are then fixed in place by bolts. Next, the cable 100 hardware 60 is installed on the insert 30, the shielding cover 70 is inserted into the outside of the cable 100 hardware 60, and the compression sleeve 80 is inserted to compress the shielding cover 70. A terminal block 90 is connected to the end face of the cable 100 hardware 60. The terminal block 90 is bolted to press the shielding cover 70 and the compression sleeve 80 to compress the shielding cover 70.

[0051] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment changes the installation method and structural layout of the existing terminal through the one-piece molding setting of the main body 10, the base 20, the insert 30 and the stress cone 40, eliminates the assembly process of each component, avoids the risk of air gaps and impurities entering due to assembly, and improves the installation efficiency and installation quality of the seat terminal.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
