What are the disadvantages of plastic industrial waterproof connectors?

As we all know, the generation of plastic industrial waterproof connector in use from time to time there will be some problems, such as: a, waterproof unreliable. Because the male and female pairs of plugs commonly used after the traditional nut butt locking design, construction personnel in the outdoor field installation, the use of manual screwing way to connect the male and female plugs, screwing with how much force, screw how many turns without a specified value, resulting in it is difficult to define whether or not completely screwed, while construction supervisors are not easy to use a simple method of acceptance one by one, unless each one of them are checked once again. A lot of outdoor engineering quality accidents are because of not tighten the seal, waterproof problems caused by the system can not run normally. For example, led landscape lighting project, often to the rainy day landscape font and outline on the lack of arms and legs of the embarrassment, mainly also connector is not waterproof caused. Second, the connecting cable with waterproof plug end of the locking fixed unreliable, from time to time there is the possibility of leakage, because the generation of "rear-mounted" waterproof connector end of the locking nut is generally defaulted to manual locking rather than tool locking, on the one hand, resulting in the operator's physical exertion is too large, and at the same time can not accurately define the locking torque, resulting in leakage of waterproof. Third, the shape and volume design is generally large. Third, the shape of the volume design is generally large, in some of the space requirements or the need for hidden design projects, often because of the larger volume and the connector body exposed, resulting in a reduction in the overall aesthetic effect of the project. Fourth, the male and female plug connection pin pin contact impedance is too high. Because the generation of products more hardware stamping is completed, male and female pin connection after the male pin and female set of inner wall contact often can not be tightly closed, resulting in high resistance, joint heating, if the high temperature conditions in the summer, easy to cause its own equipment and engineering fire hazards.
