Further, the vertical outer surface of the close-fitting section of alignment pin all protrudes from the vertical outer surface of empty avoiding section, or
The vertical outer surface of a part of close-fitting section protrudes from the vertical outer surface of empty avoiding section, and another part is then vertical outer with empty avoiding section
Surface flushes.
Further, the lateral surface of the inwall of location hole, the lateral surface of close-fitting section and empty avoiding section is vertical plane.
Further, the transition portion between the close-fitting section and empty avoiding section of alignment pin is the bevelling structure for concaving inwardly.
Further, the top of the close-fitting section is flat configuration, and its edge is then chamfering or arc corner structure；Institute
The bottom for stating empty avoiding section is flat configuration, and its edge is then chamfering structure.
The utility model is cooperated by alignment pin with location-plate and mobile phone shell, and alignment pin is made upper coarse and lower fine
Two-part structure, the design of overall location structure is not only rationally but also simple, and guide effect is had concurrently in assembling fixture by empty avoiding section,
So that alignment pin is easily plugged, and thicker close-fitting Duan Ze ensures that alignment pin has locating effect good enough, so as to avoid
Detent mechanism high cost caused by traditional positioning method, not easy-operating shortcoming.
