Speaking of plug products, I believe everyone knows what it is used for, and plugging it into the socket can provide driving power for the equipment. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors. IP54, that is, dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. Have you seen industrial plugs? It is estimated that many people will be confused. What is an industrial plug? Do you have any industrial plugs? Isn't it the plug we usually use? Actually, there are many differences between them.Plugs are divided into civil plugs and industrial plugs.I. Classification according to specifications:Cel, vce, cdd, t-faek, sbc, asi, psd, saus, pse, oni, up, etc.Second, according to the structure division:According to different structures, industrial plugs can be divided into 2-core plugs, 3-core plugs and multi-core plugs. 2-core plug: refers to a plug with a two-pin structure. The needle shapes are sheet-shaped and round. Different countries and regions use different standards, some use sheet-shaped needles and some use round needles. For example, China uses sheet-shaped needles and European-shaped needles.Three-core plug: one grounding pin for two-core or more plugs is used for grounding. Don't think it's just a contact part. If a new pin is added, there will be a series of structural problems. How to configure the size, diameter and the distance between the three positions of the pin must be fully considered, so the product structure is much more complicated than that of the double core.As for multi-core plugs, this is even more complicated, such as 4-core plugs, 5-core plugs and so on. These plugs are basically made and produced by manufacturers according to customer requirements. Besides the reasonable design structure of the products themselves, it is also necessary to consider whether the specific equipment used by the plugs meets the performance requirements and other factors. Because its design is very difficult, the general company has a special research team responsible for it.III. Classification by function:Industrial plugs can be divided into conversion plugs, injection plugs and assembly plugs according to their functions.Injection plug: This plug and wire injection mold are combined by high temperature and high pressure to form a complete combination. Once molded, the plug and wire injection mold will not be separated or disassembled. The advantage of this plug is that it is safe and durable. If we go to the market to buy plugs, you will find that most plugs are injection molded plugs.Assembly plug: Corresponding to the non-detachable feature of injection plug is the assembly plug, which is detachable.
