Abstract
A shear connector includes a plug connector having front and rear insert portions on opposite sides of the shear plane that are held together by a shear bolt scored to shear at a predetermined force, and which is threaded directly into openings in the rear insert in such a way as to eliminate relative movement between the shear bolts and the rear insert during shearing. Pin contact sections extending rearwardly from the front insert are scored at the shear plane to shear at a predetermined force. By varying clearances between the pin contact sections and the sides of the openings of the rear insert into which the pin contact sections extend, groups of contacts can be made to shear at different times, thereby reducing the force required to shear each group without unduly weakening the contacts.
Claims16
A shear connector arrangement, comprising:
- a plug connector having a shell, a rear insert positioned in the shell, a front insert connected to the rear insert by at least one shear bolt, and a plurality of contacts positioned in said front insert, wherein said front insert and rear insert include respective planar facing surfaces that form a shear plane and said shell terminates at said shear plane to permit shearing of said front insert from said rear insert without shearing of said shell, wherein said shear bolt is arranged to shear upon said shear bolt experiencing a predetermined shear force, wherein said contacts are also arranged to shear upon experiencing a predetermined shear force, and wherein said plurality of contacts extend into openings in said rear insert, respective clearances between walls of said openings and said plurality of contacts being varied to vary a timing of said rear insert engaging said contacts to cause shearing of said contacts to occur following shearing of said shear bolt;
- a receptacle connector having a shell, an insert, and a plurality of contacts arranged to mate with said contacts of the plug connector, wherein said receptacle connector is arranged to receive said front insert of said plug connector and to be secured thereto to establish an electrical connection between said plug connector contacts and said receptacle connector contacts prior to shearing of said plug connector contacts.

- a receptacle connector having a shell, an insert, and a plurality of contacts arranged to mate with said contacts of the plug connector,
- wherein said receptacle connector is arranged to receive said front insert of said plug connector and to be secured thereto to establish an electrical connection between said plug connector contacts and said receptacle connector contacts prior to shearing of said plug connector contacts,
- wherein said shear bolt includes a circumferential groove situated in the shear plane, said groove determining the force at which shearing of said bolt occurs, and
- wherein said shear bolt further includes a main body positioned in an opening in the rear insert, and a first threaded section arranged to be threaded into a sleeve in the front insert.
