Generally, according to the location of electrical connection components, electrical connection components in electrical products can be divided into two parts: external electrical connection components and internal electrical connection components. External electrical connection components refer to all electrical connection components outside the product enclosure (electrical enclosure). These electrical connection components are not included in the protection of the product enclosure (electrical enclosure). Therefore, they must meet the corresponding electric shock protection requirements separately. Internal electrical connection components refer to all electrical connection components inside the product housing (electrical housing). These electrical connection components are included in the protection of the product housing (electrical housing), so generally only need to meet the corresponding functional insulation requirements. . Taking a common rice cooker as an example (see Figure 1), it uses the power cord assembly and the power grid connection to provide working power. The power cord assembly is connected to the interior of the rice cooker through a coupler, and the coupler is connected to the internal controller through an internal wire. (temperature limiter, thermal fuse link) and heating tube and other components to form an electrical circuit. General electrical connection components are mainly composed of electrical connection parts (such as terminals, etc.), wires and cables, wire fixing devices and wire protection devices (such as separate wire sheaths, etc.) and other components. The electrical connection parts reliably fix different conductor parts together by providing appropriate mechanical force to achieve electrical connection. The key role of electrical connection components is to provide reliable connections and avoid hazards caused by poor contact between different conductors. Electrical connection parts are usually composed of non-metallic support parts and metal connection parts. The non-metallic support parts are used as the support base. In addition to being able to play an insulating role in long-term work, they are also required to be able to withstand the heat of the conductors supported in use. Deformation will occur that can lead to dangerous (for thermoplastics, this can be verified by ball pressure testing.), and it has a certain flame rating and is not a potential ignition source.
