  • Publication number: 20190020164
    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.

  • Patent number: 9595787
    Abstract: An electrical cable connector includes a cable connector housing and a latch attached to the cable connector housing. The cable connector housing includes a first set of electrical contacts and a latch channel. The latch includes an arm portion, a hinge portion, and an actuation portion. The arm portion is disposed in the latch channel and includes a pair of latch arms. The latch arms include opposing catch portions disposed at a front end thereof and are adapted to securely attach the cable connector to a mating connector by surrounding a protrusion inside a housing of the mating connector. The hinge portion extends from a back end of the arm portion. The actuation portion extends generally upwardly from the hinge portion. Pressing down the actuation portion about the hinge portion splays the latch arms such that the catch portions are moved away from each other.
