Connector Spacer is the terminal tail to do accurate positioning, to facilitate the customer plug connector on the PCB. If the space allows, can be designed to float: the customer receives the goods when the connector Spacer bottom dead center, terminal tail protrusion connector Spacer bottom length is shorter, the tail tip is the most prospective customers direct alignment PCB hole insertion and insertion process Push the connector Spacer up to position. In this case,
Designers should pay attention to how to make the connector Spacer stable positioning in the next dead point, will not fall off, it will not be self-vibration to the top dead center. In addition, in the assembly line, because the product test similar to the action of the flapper, it should also be designed to facilitate the use of simple tools to control the connector Spacer from top dead center back to the bottom dead center. The other is to consider how the connector Spacer easy to fit into the housing, to make the terminal tail through the connector Spacer hole, usually the upper edge of the connector Spacer holes made great chamfer, if the terminal has a lot of rows, you can The connector Spacer is formed in a stepped shape so as to be assembled into the connector housing in order of alignment of the rows of terminals at the time of assembly. In this case,
The concept of design is to rely on the connector Spacer to correct the terminal, but the terminal has not been corrected skew connector connector Spacer not only with the case of distortion, then the response is the connector Spacer terminal hole shape changes, so that The length of the straight section is reduced to 0.2-0.3 mm and the remaining length is made to be the chamfer portion of the above mentioned chamfer, such a shape allows the contact of the connector Spacer to correct the terminal as an approximate point contact (only in the section of the straight section Wall contact), then the reaction force applied by the terminal to the connector Spacer is less likely to cause the connector Spacer to be skewed. In the case of the Spacer connector, the stepped design has the function of protecting the terminals because the portions exposed to the plastic outside of the terminals are narrowed, and the terminals are less likely to be crushed when the operator picks and puts.
Connector Spacer bottom of the stent design can not be saved, otherwise it will cause the problem of pressure Paste. The height of the stent should be at least 0.15mm.
