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.
Claims19
A back plane assembly comprising:
- (a) a back plane including at least one hole;
- (b) a daughter board connected to the back plane;
- and
- (c) at least one guide pin mounted to the back plane, the guide pin comprising
- (i) an elongated body,
- (ii) a chamber within said body, and
- (iii) a rigid, elongated rod including a first section and a second section, said rod having the first section thereof inserted into and substantially filling said chamber, and said rod having the second section thereof passing through and engaging the hole in said back plane, thereby securing the guide pin to the back plane.
A guide pin adapted to be mounted to a printed circuit board, said printed circuit board including a hole, comprising:
- (a) an elongated body;
- (b) a chamber within said body;
- and
- (c) a rigid, elongated rod including a first section and a second section, said rod having the first section thereof inserted into and substantially filling said chamber, and said rod having the second section thereof adapted to pass through and engage the hole in said back plane, thereby securing the guide pin to the back plane.
A method of mounting a guide pin to a printed circuit board,
- said guide pin including an elongated body, a chamber within said body, and a rigid, elongated rod,
- said body including an opening at a first end,
- said rod including a first section and a second section,
- said printed circuit board including a hole, comprising the steps of:
- (a) passing the second section of said rod through the hole of said printed circuit board, whereby the second section of said rod frictionally engages the hole;
- and
- (b) passing the first section of said rod through the opening at the first end of said body, until the first section of said rod is fully inserted into, and substantially fills, said chamber.
