Cover latching mechanism

Abstract

A cover latching mechanism is provided including a base member, a cover member, and a button assembly. The cover member includes a latching hook. The button assembly includes a latching jaw and two elastic resisting arms. The latching hook and the latching jaw interlatch with each other when the cover member latches to the housing member. The elastic resisting arms are secured to the housing member and restore the button assembly back to its original position when releasing the latching of the latching hook and the latching jaw.

1 . A cover latching mechanism, comprising:
 a housing member;   a cover member comprising a latching hook; and   a button assembly comprising a latching jaw and two elastic resisting arms, the latching hook and the latching jaw interlatching with each other when the cover member latches to the housing member, the elastic resisting arms secured to the housing member and restoring the button assembly back to its original position after releasing the latching of the latching hook and the latching jaw.   
     
     
         2 . The cover latching mechanism as claimed in  claim 1 , wherein the button assembly comprises a button member, and the resisting arms and the latching jaw extend at the same side of the button member. 
     
     
         3 . The cover latching mechanism as claimed in  claim 1 , wherein each of the two resisting arms comprises an arm portion and two annular portions, the two annular portions secured to the housing member. 
     
     
         4 . The cover latching mechanism as claimed in  claim 2 , wherein the button member comprises a resisting rib resisting the housing member. 
     
     
         5 . The cover latching mechanism as claimed in  claim 1 , wherein the housing member comprises a latching block, the cover member comprises a latching protrusion, the latching protrusion latching to the latching block. 
     
     
         6 . The cover latching mechanism as claimed in  claim 1 , wherein the latching hook has an elastic sheet attached thereto for restoring the button assembly to its original position. 
     
     
         7 . The cover latching mechanism as claimed in  claim 6 , wherein the elastic sheet is wave-shaped. 
     
     
         8 . A cover latching mechanism, comprising:
 a housing member;   a cover member comprising a latching hook; and   a button assembly comprising a latching jaw and an elastic resisting arm, the latching hook detachably latched to the latching jaw for attaching or detaching the cover member to the housing member, the elastic resisting arm secured to the housing member and compressed by the surface of button assembly, and the latching hook and the resisting arm latched between the surface of the button assembly and the latching jaw.   
     
     
         9 . The cover latching mechanism as claimed in  claim 8 , wherein the button assembly comprises a button member, and the resisting arm and the latching jaw extend at the same side of the button member. 
     
     
         10 . The cover latching mechanism as claimed in  claim 8 , wherein the resisting arm comprises an arm portion and two annular portions, the two annular portions secured to the housing member. 
     
     
         11 . The cover latching mechanism as claimed in  claim 10 , wherein the button member comprises a resisting rib resisting the housing member. 
     
     
         12 . The cover latching mechanism as claimed in  claim 8 , wherein the housing member comprises a latching block, the cover member comprises a latching protrusion, the latching protrusion latching to the latching block. 
     
     
         13 . The cover latching mechanism as claimed in  claim 8 , wherein the latching hook has an elastic sheet attached thereto for restoring the button assembly to its original position. 
     
     
         14 . The cover latching mechanism as claimed in  claim 13 , wherein the elastic sheet is wave-shaped.
