Abstract
A top shell is linked to a bottom shell via a hinge portion and is locked to the latter, so that the top shell is prevented from separating from the bottom shell when the hinge portion is broken. The top shell is formed unitarily and in one piece with the bottom shell via the hinge portion. An end portion of the top shell is notched with a semi-circular groove to form a fixing recess, and an end portion of the bottom shell is formed to have a semi-circular projection to form a fixing protrusion. The top shell is then superposed onto the bottom shell, and they are locked by a locking protrusion and a locking recess. At the same time, the fixing protrusion is press-fitted into the fixing recess, so that the top shell is immobilized at a given position relative to the bottom shell.
Claims12
A device for fixing a first shell and a second shell of a housing, said first shell being integrally linked to said second shell via a hinge portion so as to enable an opening and closing movement;
- said first shell including a locking protrusion, and said second shell including a locking recess, so that said locking protrusion and said locking recess can be locked;
- said second shell further including at least one fixing protrusion, and said first shell including a corresponding fixing recess, said at least one fixing protrusion being configured to be press-fit into said corresponding fixing recess, so that, when said locking protrusion and said locking recess are locked together, said locking protrusion and said locking recess are immobilized by said at least one fixing protrusion and said corresponding fixing recess;
- wherein said first shell and said second shell respectively include an end portion distal to the end portion to which said hinge portion is linked, and said at least one fixing protrusion is in the form of a semi-cylindrical column projecting from said end portion of said second shell, whereas said corresponding fixing recess is in the form of a complementary semi-circular groove and is located at said end portion of said first shell, such that, when said first shell and said second shell are locked together, said at least one fixing protrusion fits into said corresponding fixing recess.
An electrical connector housing including a first shell and a second shell, said first shell being integrally linked to said second shell via a hinge portion so as to enable an opening and closing movement;
- said first shell including a locking protrusion, and said second shell including a locking recess, so that said locking protrusion and said locking recess can be locked;
- said second shell of said electrical connector housing further including at least one fixing protrusion, and said first shell including a corresponding fixing recess, said at least one fixing protrusion being configured to press-fit into said corresponding fixing recess, so that, when said locking protrusion and said locking recess are locked together, said locking protrusion and said locking recess are immobilized by said at least one fixing protrusion and said corresponding fixing recess;
- wherein said first shell and said second shell respectively include an end portion distal to the end portion to which said hinge portion is linked, and said at least one fixing protrusion is configured as a semi-circular column projecting from said end portion of said second shell, and said corresponding fixing recess is in the form of a complementary semi-circular groove and is located at said end portion of said first shell, such that, when said first shell and said second shell are locked together, said at least one fixing protrusion fits into said corresponding fixing recess.
A wire harness housing including a first shell and a second shell, said first shell being integrally linked to said second shell via a hinge portion so as to enable an opening and closing movement;
- said first shell including a locking protrusion, and said second shell including a locking recess, so that said locking protrusion and said locking recess can be locked;
- said second shell of said wire harness housing further including at least one fixing protrusion, and said first shell thereof including a corresponding fixing recess, said at least one fixing protrusion being configured to be press-fit into said corresponding fixing recess, so that, when said locking protrusion and said locking recess are locked together, said locking protrusion and said locking recess are immobilized by said at least one fixing protrusion and said corresponding fixing recess;
- wherein said first shell and said second shell respectively include an end portion distal to the end portion to which said hinge portion is linked, and said at least one fixing protrusion is in the form of a semi-cylindrical column projecting from said end portion of the second shell, and said corresponding fixing recess is in the form of a complementary semi-circular groove and located at said end portion of the first shell, such that, when said first shell and said second shell are locked together, said at least one fixing protrusion fits into said corresponding fixing recess.
