Retainer for Circuit or Cable Card Assembly

Retainers 10 snap over the ends of double-sided connector block 15 and thereby retain card plug 16, which is permanently attached to the circuit card or cable card 17, with respect to connector block 15, as seen in Figs. 1 and 2.

Connector block 15 is provided with a series of connector pins 20 on both its upper and lower surfaces. Card plug 16 includes a recess for receiving each of the upstanding pins 20 for forming electrical connections between the circuit card or cable card 17 and these pins.

Retainers 10 are made of bendable plastic material that is nonconductive. The distance between the end of projection 12 on a retainer 10 and ledge 14 on this retainer 10 is slightly less than the distance between points a and b respectively on the upper surface of plug 16 and the lower surface of block 15 at an outer edge of block 15. A retainer 10 includes an upstanding knob 11. When knob 11 is pushed downwardly, as seen in Fig. 1, projection 12 engages plug 16 and ledge 14 stretches over and locks onto the edge of connector block 15, with retainer 10 moving from its position shown in Fig. 1 into its position shown in Fig.
2. Retainer 10 thus resiliently locks plug 16 onto the upper surface of connector block 15 and prevents plug 16 from vibrating or moving upwardly to disengage it with respect to the upstanding pins 20 of connector block 15. To remove retainer 10, a slight outward pressure on tang 13 of retainer 10 will dise...
