A general term for parts such as gussets, spring bars, and hooks for splicing accessories for rails and under-rail components. According to the material properties, it is divided into two types: rigid and elastic. The rail splicing fitting has a rigid splicing fitting with a rigid crimping member, and an elastic splicing fitting with a elastic crimping member. The elastic buckle can store the strain energy by means of pre-deformation, thereby adjusting the fluctuation state of the buckle pressure. Rigid crimping parts are not possible, so the anti-climbing performance of elastic splicing accessories is superior to rigid splicing fittings.
