Conveyor with hinge pin retention plug with snap fit

A conveyor having an intended direction of travel comprising:

• a first link module extending transversely of the intended direction of conveyor travel and including a trailing portion, said trailing portion including a plurality of ears spaced apart at distances to define therebetween a first series of spaces;
• a second link module extending transversely of the intended direction of conveyor travel, said second link module including a leading portion having a plurality of ears spaced apart at distances to define therebetween a second series of spaces, said plurality of ears on said second link module are located in said spaces defined by said plurality of ears of said trailing portion of said first link module, wherein one of said leading and trailing plurality of ears includes a laterally located outer side ear having an outer side surface extending along the direction of intended conveyor travel, said outer side ear includes a bore extending from said outer side surface transversely of the direction of intended conveyor travel and an elongated recess located in said outer side surface and extending radially from said bore along the direction of intended conveyor travel, said outer side ear also includes an aperture extending in said outer side ear transversely to said bore, said aperture communicates with said bore and is defined, in part, by an abutment surface spaced inwardly from said outer side surface, said abutment surface extends along the direction of intended conveyor travel;
• a retention plug including a cylindrical barrel portion extending in said bore, said retention plug includes an outer end and a flange portion extending from said outer end, said flange portion is located in said elongated recess;
• and wherein said retention plug also includes a resilient tab portion extending radially from said barrel portion in inwardly spaced relation from of said flange portion, said resilient tab portion is in engagement with said abutment surface of said outer side ear.
