Technical Field
[0001] The utility model relates to the technical field of circuit breaker wiring equipment, in particular to a plug-in device. Background Art
[0002] In the field of electrical connection and transmission, plug-in devices are widely used because of their ease of installation, maintenance and replacement. Traditional plug-in devices usually include a base and a conductive component installed in the base, which is used to achieve electrical connection and transmission. However, in existing plug-in devices, the structure of the conductive component is often complex, the installation and disassembly process is cumbersome, and the arc isolation effect between the conductive components is not good. Especially in high-voltage and high-current application scenarios, the generation and spread of arcs may have a serious impact on the safety and reliability of the device. In addition, the matching method of the gears and copper petal components in traditional plug-in devices is also insufficient, such as loose matching and easy loosening, which also affects the electrical performance and service life of the device. At the same time, the material selection of the base is also directly related to the insulation performance and mechanical strength of the device, and the base materials in the prior art are often difficult to meet these requirements. Utility Model Content
[0003] In view of this, the purpose of the utility model is to provide a plug-in device with simple structure, convenient installation, stable electrical performance, and safety and reliability.
[0004] In order to achieve the above purpose, the utility model adopts such an insertion device, including a base, wherein the base is provided with a plurality of installation cavities, each installation cavity is provided with a conductive component, the conductive component includes a copper rod, one end of the copper rod is installed in the installation cavity of the base, and the other end extends out of the base, the copper rod is keyed to a gear at one end located in the installation cavity, the gear is provided with a plug-in slot for plugging, a copper petal component is plugged into the plug-in slot, the outer wall of the copper petal component is provided with a sheath, the sheath is installed in the installation cavity, arc isolation plates are provided between the conductive components, the arc isolation plates are fixed to the base by plugging, and are used to isolate the arcs between adjacent conductive components.
[0005] The beneficial effects of the above structure are: by adopting a modular design, the various components are connected by plug-in, key connection, etc., so that the structure of the device is simple and clear, the installation and disassembly process is convenient and quick, and the work efficiency is greatly improved. The setting of the arc isolation plate effectively isolates the arc between adjacent conductive components, prevents the spread and diffusion of the arc, protects the safety and reliability of the device, and extends the service life of the device. In addition, the arc isolation plate further enhances the stability of the installation and the reliability of the arc isolation. The key connection between the copper rod and the gear ensures the stability of the transmission. The plug-in structure of the copper petal assembly enables good contact, and the protective effect of the sheath jointly ensures that the electrical performance of the device is stable and reliable.
[0006] The utility model is further configured that the copper petal assembly includes a plurality of copper petals, which are distributed in an annular array and plugged into the gear, and a tension spring is mounted on the outer wall of the copper petal. The copper petals are distributed in an annular array, so that the contact area between the copper petal assembly and the copper rod is larger and the contact is more uniform, thereby improving the reliability and stability of the electrical connection. The design of the plurality of copper petals can disperse the current, reduce the risk of local overheating, and improve the current carrying capacity of the device. The mounting of the tension spring makes the copper petal assembly have a certain elasticity, which can adapt to copper rods of different sizes or shapes and ensure good contact.
[0007] The utility model is further configured that a through slot is provided on the copper rod, a cylindrical pin is provided in the through slot and runs through the copper rod horizontally, and an arc slot is provided on the base at a position corresponding to the cylindrical pin. The cylindrical pin is inserted into the through slot of the copper rod and matches with the arc slot of the base, thereby forming a stable connection mode. This design effectively limits the axial and radial movement of the copper rod in the base, and enhances the stability of the entire conductive component.
[0008] The utility model is further arranged that the copper rod is provided with a clamp between the cylindrical pin and the copper petal assembly. The clamp makes the position of the copper rod between the cylindrical pin and the copper petal assembly more stable, effectively preventing the copper rod from loosening or shifting during use.
[0009] The utility model is further configured that the base is provided with a fool-proof boss at the position corresponding to the arc isolation piece. The design of the fool-proof boss can effectively prevent the arc isolation piece from making mistakes during installation.
[0010] The utility model is further configured that the base is made of bakelite material. Bakelite has excellent insulation performance. As a base material, bakelite can effectively prevent current leakage and ensure the safe operation of electrical equipment. In a humid, dusty or corrosive environment, the insulation performance of the bakelite base is more stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
