Terminal accuracy is a key factor in determining the stability of connector signal transmission. It is mainly affected by the dimensional accuracy of the mold, the accuracy of the mold alignment, and the accuracy of the punch equipment. Specifically, the terminal accuracy we are talking about includes dimensional accuracy, shape accuracy and position accuracy.
(1) Dimensional accuracy
Dimensional accuracy refers to the degree to which the actual size of the terminal is close to the ideal size, which is commonly expressed as dimensional tolerance. The higher the tolerance number, the lower the dimensional accuracy. The smaller the tolerance, the higher the dimensional accuracy.
(2) Shape accuracy
Shape accuracy refers to how close the actual shape of the terminal is to the ideal shape. The shape tolerance includes six kinds of straightness, flatness, roundness, cylindricity, line profile, and surface profile.
(3) Position tolerance
Positional tolerance refers to the degree to which the actual positional wall between the surfaces, axes or symmetry planes of a terminal approximates the ideal positional gain. Terminal position tolerances include parallelism, perpendicularity, inclination, coaxiality, symmetry, position, circular runout, and full runout.
When the connector manufacturer decides the stamping accuracy of the terminal, the equipment conditions and processing cost of the production must be considered. Generally speaking, the precision of the terminal only needs to meet the technical requirements. Excessive pursuit of high precision will cause waste. TXGA is a professional connector manufacturer. It has provided customers with precise and reliable connector products for 16 years. It can choose the appropriate production process according to the customer's product application to ensure that the product performance meets customer needs.
