The plastic cover type means that the cable the connector have been injected packaged before leaving the factory. It has the advantages of simple structure low total cost. However, the number of PINs the length of the cable cannot be changed. End users need to confirm the parameters with the manufacturer. Produced, unable to complete the inventory pre-production; post-installed type refers to the customer does bring any cable connectors at that time.

At the construction site, you can cut the length of the cable according to the engineering needs on the site by simplifying things. After inserting the cable into the connector, a nut is provided at the end to fix waterproof the cable. This type of connector plug has a relatively complicated structure. The advantages of high installation sensitivity are especially suitable for on-site emergency, which can complete mass production in large quantities.

When choosing a waterproof adaptor plug, the first priority is to comply with the relevant electrical, installation, connection, insulation, protection other technical specifications. Because some of the specifications practices used in the planning of production are borrowed other occupations, the use time is relatively long, many specifications cannot meet the requirements of the rapid change of LED occupations.

Therefore, in addition to looking at the fundamental technical specifications, the selection of UL yellow card specifications is the standard, the requirements of the individual specifications are relatively low, which leads to the production of many home workshops. Therefore, the static environment is required to be produced, plus laboratory tests All tests are conducted in terms of normative terms normative environments. Therefore, after many accidents, the products were found to be qualified when tested according to the technical specifications, the actual use environment is very different. It should exceed the technical specifications produced at the time, pay attention to the practical experience. situation.

Second look at the structural principle planning, if the selected structural principle planning expires, even if the quality control of the production process is very good, reliability long-term weather resistance in the field cannot be more reliable than the new generation of products. Next, we need to look at the official scale control accuracy of the fittings. The waterproof connector plug has high requirements for scale accuracy. Many products have the same shape structure. To ensure the stability of the connection, it is necessary to carefully measure with a caliper when selecting the model. The general quality The scale of good cooperation has changed much, on the contrary, the scale has changed a lot.
