The plugging and unplugging force of a rectangular connector is a key parameter that has an important impact on the ease of use and reliability of the connector.
The size of the plugging and unplugging force is first related to the design of the connector's contacts. The shape, size and material of the contacts are the main factors. For example, the thickness and length of the pins will affect the friction during plugging and unplugging. Thicker pins have a larger contact area with the inner wall of the socket during plugging and unplugging, and the friction increases accordingly, resulting in greater plugging and unplugging force. The material of the contact, such as the hardness and surface roughness of the metal, will also change the resistance during plugging and unplugging. If the surface of the material is not smooth enough, the friction will increase, resulting in an increase in plugging and unplugging force.
Secondly, the internal structure and mechanical design of the connector also play a key role in the plugging and unplugging force. The internal locking mechanism, the elastic coefficient of the shrapnel, etc. will affect the plugging and unplugging force. For example, a shrapnel with good elasticity can provide a suitable plugging and unplugging force while ensuring the stability of the connection. When inserted, the shrapnel will produce a certain deformation resistance, and when pulled out, it will rely on its own elasticity to restore to its original state. The force generated in this process is part of the plugging and unplugging force.
In addition, external environmental factors will also affect the plugging and unplugging force. Under different temperature and humidity conditions, the physical properties of the material will change. For example, in a high temperature environment, some plastic shells may become soft, causing deformation of the internal structure and reducing the plugging and unplugging force; in a high humidity environment, metal contacts may oxidize, increasing the contact resistance and may also change the plugging and unplugging force.
The size of the plugging and unplugging force is crucial to actual use. If the plugging and unplugging force is too large, it will make the plugging and unplugging operation difficult, and may even damage the connector or the equipment connected to it; if the plugging and unplugging force is too small, it may cause unstable connection, easy to loosen, poor contact and other problems. Therefore, in the design and manufacturing process of the Rectangular Connector, it is necessary to comprehensively consider various factors to determine the appropriate plugging and unplugging force to ensure that it can work reliably and conveniently in various application scenarios.
