Abstract

A press-contact pogo pin connector is provided which has a machining cost lower than those of conventional connectors, can be easily reduced in height, and does not cause instantaneous interruption. A molded insulating housing has a cylinder hole. A pin installed inside the cylinder hole is urged by a coil spring installed inside the cylinder hole so as to protrude from the housing. A flange portion on the rear side of the pin urged by the coil spring abuts against the peripheral portion of the front opening of the cylinder hole on the front side of the housing so that the pin is prevented from falling off. A contact integrally includes a substrate connection terminal portion and a contact spring portion that extends inside the cylinder hole and is brought into press-contact with the pin at all times. The contact is secured to the housing.

Claims

1. A press-contact pogo pin connector comprising:

a molded insulating housing having a cylinder hole with a front opening of the cylinder hole provided on a front side of the housing;

a pin that includes a flange portion at a rear end thereof and is installed inside the cylinder hole;

a coil spring that is installed inside the cylinder hole and urges the pin so that the pin protrudes from the housing; and

a contact that includes a substrate connection terminal portion and a contact spring portion and is secured to the housing, the substrate connection terminal portion and the contact spring portion being integrally provided, the contact spring portion extending inside the cylinder hole and being brought into press-contact with the pin at all times,

wherein the flange portion of the pin urged by the coil spring abuts against a peripheral portion of the front opening of the cylinder hole so that the pin is prevented from falling off; and

wherein the pin includes a main pin body formed by bending a metal strip into a U-shape with two parallel portions and the flange portion that is integrally formed on each side end edge of each of the two parallel portions so as to protrude therefrom.

2. The press-contact pogo pin connector according to claim 1, wherein the main pin body includes a spring receiving portion formed by bending an end portion of one of the two parallel portions that form the U-shape toward the other parallel portion, and an end of the coil spring abuts against the spring receiving portion.
