Abstract

Multiple-row zero-insertion-force connectors require a special device to properly position pins for insertion into the holes of a printed circuit board. Such a device is described in the following. The device consists of a connector body 1 (Fig. 1) which moves in the direction of locating combs 2 such that pins 3 on connector 1 pass between teeth 4 of combs 2. (Image Omitted) As seen in Fig. 2, the combs 2 are arranged in pairs consisting of a lower comb 2b with locator grooves 5 on one side of each of the teeth and an upper comb 2a with smooth surfaces on both sides of each tooth. The pins 3 pass through the lower comb 2b and the upper comb 2a. The pins are aligned in the correct position when the upper comb 2a (Fig. 3) remains stationary while the lower comb 2b is actuated in the direction indicated by the arrows.

Multiple Pin Location Device

Multiple-row zero-insertion-force connectors require a special device to properly position pins for insertion into the holes of a printed circuit board. Such a device is described in the following. The device consists of a connector body 1 (Fig. 1) which moves in the direction of locating combs 2 such that pins 3 on connector 1 pass between teeth 4 of combs 2.

(Image Omitted)

As seen in Fig. 2, the combs 2 are arranged in pairs consisting of a lower comb 2b with locator grooves 5 on one side of each of the teeth and an upper comb 2a with smooth surfaces on both sides of each tooth. The pins 3 pass through the lower comb 2b and the upper comb 2a. The pins are aligned in the correct position when the upper comb 2a (Fig. 3) remains stationary while the lower comb 2b is actuated in the direction indicated by the arrows. The upper comb 2a acts as a back guide as the locator groove 5 of the lower comb 2b actuates toward the pins to be aligned. As the grooves 5 come into contact with the pin, the front corner of pin is engaged by an angled ramp which moves the pin into the desired position. Fig. 4 shows the pins in the located position.
