Description

Technical Field

[0001] This utility model relates to the field of cable joint equipment technology, and in particular to a cable joint that is resistant to breakage. Background Technology

[0002] In existing technologies, cables undergo long-term reciprocating motion, which often causes wear on the sheath layer. Therefore, protection is needed to prevent the reciprocating motion of the cable at the connection between electrical equipment and the cable.

[0003] In practice, existing technologies place the cable outside the motor without any protective device, resulting in poor protection during actual use and easy breakage. This not only poses safety hazards but also affects the use of multiple electrical devices, causing numerous inconveniences.

[0004] Therefore, this utility model provides a cable connector that is resistant to breakage. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cable connector that is resistant to breakage.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a breakage-resistant cable connector, including a protective shell.

[0007] An insulating sleeve is installed at one end of the protective shell, and a first connecting threaded sleeve is installed at one end of the insulating sleeve. A first sealing flange is fitted on the outer side of the first connecting threaded sleeve.

[0008] The other end of the protective housing is equipped with a second connecting threaded sleeve, and a second sealing flange is fitted on the outside of the second connecting threaded sleeve;

[0009] A sealing connecting plate is installed inside the protective shell. A connecting side plate is installed on the side of the protective shell near the insulating sleeve. Multiple reinforcing connecting rods that penetrate the sealing connecting plate and extend to the inner wall of the protective shell are installed inside the connecting side plate. The multiple reinforcing connecting rods are symmetrically distributed. A sealing ring is installed on the side of the protective shell near the second connecting threaded sleeve.

[0010] The first threaded connecting sleeve has a rubber ring installed inside for connection with the connecting side plate, and the second threaded connecting sleeve has a shielding sleeve installed inside for connection with the sealing ring. During use, the entire device is installed in the order of the second threaded connecting sleeve, the protective shell, and the insulating sleeve. One end of the cable is installed from inside the first threaded connecting sleeve, passing through the rubber ring, the insulating sleeve, the connecting side plate, the sealing connecting plate, the protective shell, the second sealing flange, and the second threaded connecting sleeve, until it is removed from one end of the second threaded connecting sleeve. During normal use, the insulating sleeve and rubber ring ensure electrical isolation and safety, while the second threaded connecting sleeve prevents electromagnetic interference, providing multiple layers of protection for the internal cable, extending the device's service life, and facilitating quick maintenance. Furthermore, the entire device does not include electrical equipment, saving on overall installation and operating costs.

[0011] In a preferred embodiment, the outer side of the insulating sleeve is fitted with a limiting nut. The limiting nut reinforces the insulating sleeve and improves the sealing effect when the insulating sleeve and the protective shell are connected. The rubber ring has a fourth mounting groove inside, and the first sealing flange has a third mounting groove inside for use with the first connecting threaded sleeve. The third mounting groove inside the first sealing flange allows for normal connection with the first connecting threaded sleeve, facilitating adjustment of the installation position during use. The fourth mounting groove inside the rubber ring allows for normal cable penetration and installation.

[0012] The technical advantages of adopting the above-mentioned further solution are: by designing a third mounting groove inside the first sealing flange to connect normally with the first connecting threaded sleeve, it is convenient to adjust the installation position during use; and by opening a fourth mounting groove inside the rubber ring to allow the cable to pass through normally during installation.

[0013] In a preferred embodiment, the sealing ring has a first mounting groove inside, and the protective shell has a cavity inside that is fitted with a sealing connecting plate. The cable is limited and installed by the cavity and the first mounting groove. The protective shell itself provides protection for the cable and ensures the physical safety of the cable. The connecting side plate has a second mounting groove inside, and the reinforcing connecting rod has a second mounting groove with the same structure inside. The cable is installed normally by passing through the two second mounting grooves.

[0014] The technical effect of adopting the above-mentioned further solution is that the reinforcing connecting rod has a second mounting groove with the same structure inside, and the cable can be installed normally by passing through the two second mounting grooves.

[0015] In a preferred embodiment, the top of the protective housing is equipped with a positioning bolt extending into the interior. The positioning bolt is used to limit the top of the cable through which the installation is carried out, thereby improving the overall stability during installation. The shielding sleeve has a fifth mounting groove inside, and the second sealing flange has a sixth mounting groove inside that is used to cooperate with the second connecting threaded sleeve. By designing the sixth mounting groove inside the second sealing flange to cooperate with the second connecting threaded sleeve for normal connection, it is convenient to adjust the installation position during use. The fifth mounting groove inside the shielding sleeve is used to facilitate the normal through-installation of the cable.

[0016] The technical advantages of adopting the above-mentioned further solution are: by designing a sixth mounting groove inside the second sealing flange to connect normally with the second connecting threaded sleeve, it is convenient to adjust the installation position during use; and by opening a fifth mounting groove inside the shielding sleeve to allow the cable to pass through and be installed normally.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] By incorporating a protective outer shell, an insulating sleeve, and a second threaded connecting sleeve, the insulating sleeve is reinforced and limited by a limiting nut during use, improving the sealing effect when the insulating sleeve and protective outer shell are connected. A third mounting groove designed inside the first sealing flange allows for normal connection with the first threaded connecting sleeve, facilitating adjustment of the installation position during use. A fourth mounting groove inside the rubber ring allows for normal cable penetration, and the cavity within the first mounting groove limits cable installation. The protective outer shell itself provides protection for the cable, ensuring its physical safety. A sixth mounting groove designed inside the second sealing flange allows for normal connection with the second threaded connecting sleeve, facilitating adjustment of the installation position during use. During installation, the entire device is assembled in the following order: second connecting threaded sleeve, protective housing, and insulating sleeve. One end of the cable is installed from inside the first connecting threaded sleeve, passing through the rubber ring, insulating sleeve, connecting side plate, sealing connecting plate, protective housing, second sealing flange, and second connecting threaded sleeve in sequence, until it is removed from one end of the second connecting threaded sleeve. In normal use, the insulating sleeve and rubber ring are used to ensure electrical isolation and safety, while the second connecting threaded sleeve is used to prevent electromagnetic interference. This provides multiple layers of protection for the cable installed inside, reducing cable breakage and extending the service life of the equipment. It also facilitates quick maintenance. Furthermore, the entire device does not have any electrical equipment installed, saving on overall installation and operating costs. Attached Figure Description
