Description

Auxiliary device for protecting connector

Technical Field

Background

The connector is an indispensable component of an electronic device, and its form and structure are diversified, and there are various different forms of connectors depending on an application object, frequency, power, application environment, and the like.

Mechanical properties are one of the basic properties of a connector, and insertion and extraction forces are important mechanical properties in terms of the connection function. The insertion and extraction force is divided into an insertion force and an extraction force, and the requirements of the insertion force and the extraction force are different. In the relevant standards, there are maximum insertion force and minimum separation force regulations, which indicate that if the insertion and extraction force is not appropriate, the reliability of the contact is affected, with the continuous development of electronic technology, connectors with multiple cores are more and more common, the increase of the number of cores also means the increase of the insertion and extraction force, and the cables (signal cables, etc.) connected with the connectors become thicker and heavier, so that the connectors are more and more laborious to insert and extract by hand, and the reliability of the contact is lower and lower. However, although the connector is connected from the outside, the inner pin of the connector is not well contacted, and the connector plug is not inserted into the position at a glance when the connector is opened, or the pin of the connector is bent.

In addition, in underwater engineering, a watertight connector, such as those of the brand names of subcon, seaconal wetconnectors and the like, is often used, and the watertight connector is entirely made of rubber, and the contact pin is made of copper. Plugs of some rubber type connectors are easy to fall off, and although plugs of some rubber type connectors are provided with anti-falling rubber rings, the rubber rings are easy to break, and the reliability is low; in addition, the rubber-type connectors are very soft and easily damaged, and the phenomena that some connector pins are bent by careless touch and the rubber of the socket is torn are often found, and once the connectors are in trouble, the connectors must be replaced, the replacement process is troublesome, and finally the whole electronic bin is required to be subjected to pressure test under a pressure kettle. Therefore, the requirement of short maintenance time for quick plugging and unplugging is met, and how to solve the technical problems that the plug of the connector is easy to drop off and damage and the like becomes a problem to be solved urgently.
