  • Patent number: 10236653
    Abstract: A pick and place cap is configured to facilitate picking and placing a connector when the cap is assembled to the connector. The cap includes a first wall defining a width, W, and a length, L of the cap. A second wall extends perpendicularly from the first wall and defines a height, H, of the cap. The cap also includes spaced apart parallel first, second, and third ribs extending from the first and second walls. Each of the first, second, and third ribs have the same first width, W1, and the same first height, H1. The first width and first height are less than the respective width and height of the cap. The cap includes spaced apart parallel fourth and fifth ribs disposed between and parallel to the second and third ribs. The fourth and fifth ribs are spaced part from the second wall and extend from the first wall. Each of the fourth and fifth ribs have the same second height, H2, which is greater than the first height, H1.
