Does the subject want to ask "the reason for the crease when the pin foot of type-CSM is bent"? Interface quality problem, improper use of interface.

1. Interface quality problem: There are defects in the production process of the type-csmtpin interface, such as the plastic part of the interface is too hard or too thin, or the metal part of the interface is not completely inserted into the equipment, resulting in creases in use. Before using the interface, check the interface for any defects or damage. If problems are found, replace the interface in time.

2. Improper use of the interface: Insert the type-csmtpin interface in an incorrect way, such as using too much force or twisting the interface, which will lead to creases when the interface is bent. When using this interface, insert the interface according to the equipment manual or other reliable guidelines to avoid using too rough methods.
