Description

Technical Field

[0001] This utility model relates to the field of cable connectors, and in particular to an anti-arc device for cable connectors. Background Technology

[0002] Cable connectors are electrical devices used to connect two or more cables, ensuring the safe and reliable transmission of current, signals, or data. During cable connection, disconnection, or maintenance, arc flashover may occur. Arc flashover is a high-energy electrical fault that can generate extremely high temperatures, intense light radiation, and explosive pressure waves in a short period of time, causing serious damage to equipment and personnel. Arc protection measures are required for cable connectors to protect electrical equipment and operators from arc flashover hazards. This is generally achieved through arc protection devices. Existing arc protection devices are usually fixed to the cable connector, making them inconvenient to replace or remove quickly.

[0003] To address the above problems, an anti-arc device for cable connectors has been developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing anti-arc devices, which are usually fixed on cable connectors and are not convenient for quick replacement or disassembly, this utility model provides an anti-arc device for cable connectors.

[0005] The technical solution of this utility model is as follows: An arc-proof device for a cable connector includes an outer frame, a threaded groove on the outer frame, a first cavity inside the outer frame, screw threads on the inner side of the first cavity, a second cavity in the middle of the outer frame, and an arc-proof cavity in the middle of the outer frame, the arc-proof cavity being located inside the second cavity, a plurality of arc-proof plates being provided inside the arc-proof cavity, a connector being threadedly connected to the threaded groove, the connector being slidably connected to the second cavity, and a sealing ring being provided inside the first cavity.

[0006] Optionally, the screw threads facilitate quick connection of multiple cable connectors.

[0007] Optionally, the anti-arc cavity is a circular structure that conforms to the shape of the cable.

[0008] Optionally, the arc-proof cavity facilitates cable connection.

[0009] Optionally, the arc-blocking plate can effectively block the propagation of electric arc.

[0010] Optionally, the sealing ring can prevent high-temperature gases, metal fragments and other harmful substances generated by the electric arc from leaking from the inside of the equipment to the external environment, and can also prevent external moisture, dust and other pollutants from entering the inside of the equipment, thereby extending the service life of the equipment and improving safety.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0012] This invention allows the connector to connect with the threaded groove by rotating the connector, and then to slide with the anti-arc cavity. The cable is then passed through the anti-arc plate, which effectively blocks the propagation of the electric arc. To prevent external moisture, dust and other contaminants from entering the equipment, a sealing ring can be used to seal it. The threaded connection between the anti-arc cavity and the connector makes the installation and disassembly of the connector and the anti-arc cavity more convenient. Attached Figure Description

[0019] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] An arc protection device for a cable connector, such as Figures 1-5As shown, the device includes an outer frame 2 with a threaded groove 3 and a first cavity 7 inside. The inner side of the first cavity 7 has screw threads 4, which facilitate quick connection of multiple cable connectors 1. A second cavity 8 is located in the middle of the outer frame 2, and an anti-arc cavity 5 is also located in the middle of the outer frame 2. The anti-arc cavity 5 is a circular structure conforming to the shape of the cable, facilitating cable connection. The anti-arc cavity 5 is located inside the second cavity 8, and several anti-arc plates 6 are provided inside the anti-arc cavity 5. The anti-arc plates 6 can effectively block the propagation of electric arc. Connectors 1 are threadedly connected to the threaded groove 3, and the connectors 1 are slidably connected to the second cavity 8. A sealing ring 9 is provided inside the first cavity 7. The sealing ring 9 can prevent high-temperature gases, metal fragments, and other harmful substances generated by the electric arc from leaking from the inside of the device to the external environment, and can also prevent external moisture, dust, and other pollutants from entering the device, thereby extending the service life of the device and improving safety.

[0021] It should be noted that cable connector 1 is an electrical device used to connect two or more cables to ensure the safe and reliable transmission of current, signals, or data. During cable connection, disconnection, or maintenance, arc flashover may occur. Arc flashover is a high-energy electrical fault that can generate extremely high temperatures, intense light radiation, and explosive pressure waves in a short time, causing serious damage to equipment and personnel. Arc protection measures are required for cable connector 1 to protect electrical equipment and operators from arc flashover hazards. This is generally achieved through arc protection devices. Existing arc protection devices are usually fixed to cable connector 1, making quick replacement or disassembly inconvenient. This device enables quick installation and disassembly of cable connector 1 and arc protection device. By rotating connector 1, connector 1 connects with threaded groove 3, and then slides into arc protection cavity 5. Next, the cable is passed through arc protection plate 6, which effectively blocks the propagation of arc. To prevent external moisture, dust, and other contaminants from entering the equipment, sealing ring 9 can be used to seal it. The threaded connection between arc protection cavity 5 and connector 1 makes installation and disassembly of connector 1 and arc protection cavity 5 more convenient.

[0022] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
