A zero-play pin clevis joint for deployable space structures includes a tapered pin and tapered bores extending through a shackle and through a tang such that the tapered pin is received in the tapered bores. Spring washers urge the tapered pin into the tapered bores of the shackle and also urge the tang onto the tapered pin. Deployable truss structures use a plurality of the aforementioned zero play pin clevis joints to connect a plurality of truss tubes. The angle of taper for the various components is preferably about 12°included angle.

A pin clevis joint for connecting first and second structural members of a deployable space structure, comprising: a substantially U-shaped shackle connected to an end of the first structural member, and having two opposite side, axially extending projections; a tapered bore extending transversely through the two projections of the shackle, the tapered bore forming two conically shaped and aligned surfaces in the two projections of the shackle; an axially extending tang connected to an end of the second structural member and having a tapered bore extending transversely therethrough, the tapered bore forming a conically shaped surface in the tang, the conically shaped surfaces of the two projections and the tang having an equal angle of slope and combining to form a substantially continuous cone-shaped bore for receiving a pin; said pin comprising a headed end, an opposite end, and a conically shaped sidewall tapering from the headed end to the opposite end, the conically shaped sidewall having an angle of slope equal to the angle of slope for the conically shaped surfaces of the two projections of the shackle and the tang, the pin passing through the tapered bores of the tang and shackle and fitting precisely therein with substantially zero free-play; fastener means connectable to the opposite end of the pin; first spring means for biasing the pin onto the conically shaped surfaces of the two projections of the shackle; and second spring means for biasing the tang onto the sidewall of the pin.
