  • Plastic guide pin with steel core
    Patent number: 5690504
    Abstract: A guide pin that mounts easily to a back plane including a hollow, elongated body molded from plastic, and a rigid, elongated steel rod. The plastic body has an opening located at one end. The rod is first inserted into a hole in the back plane. The rod is then inserted into the body through the opening. The action of inserting the rod into the back plane causes the rod to frictionally engage the hole in the back plane, thereby securing the guide pin to the back plane. The portion of the steel rod located inside the plastic body gives the guide pin sufficient strength and rigidity for most back plane assembly applications.
