Abstract

An electronic apparatus includes a housing having first and second cover bodies covering opposite first and second ends thereof, and a switch device including a support member, and a switch assembly mounted on and slidable relative to the support member and having first and second contact points. When one of the first and second cover bodies covers one of the ends of the housing and pushes one of the first and second contact points with the other one of the first and second contact points being unblocked, the switch assembly is placed in an OFF state. When the first and second cover bodies cover the ends of the housing and push the first and second contact points toward each other, the switch assembly is switched from the OFF state to an ON state.

First claim

What is claimed is:

1 . An electronic apparatus comprising:
a housing including a first cover body for covering a first end thereof, and a second cover body opposite to said first cover body for covering a second end of said housing which is opposite to said first end; and a switch device disposed in said housing and including
a support assembly including a support member, and
a switch assembly mounted on and slidable relative to said support member and having a sliding portion slidably connected to said support member, a first contact point pushable by said first cover body, and a second contact point opposite to said first contact point and pushable by said second cover body, said switch assembly being slidable relative to said support assembly in a first direction and a second direction opposite to said first direction, and being switchable between OFF and ON states;
wherein, when said first cover body covers said first end of said housing and pushes said first contact point to move along said first direction with said second contact point being unblocked, or when said second cover body covers said second end of said housing and pushes said second contact point to move along said second direction with said first contact point being unblocked, said switch assembly is placed in said OFF state; and wherein, when said first and second cover bodies respectively and simultaneously cover said first end and said second end of said housing, said first and second contact points are pushed toward each other to switch said switch assembly from said OFF state to said ON state.

2 . The electronic apparatus as claimed in claim 1 , wherein said first and second contact points are spaced apart from each other when said switch assembly is in said OFF state.

3 . The electronic apparatus as claimed in claim 2 , wherein said support member has an abutment surface, said sliding portion having at least one first end surface, said switch assembly being slidable between a first position, where said at least one first end surface abuts against said abutment surface, and a second position, where said at least one first end surface is away from said abutment surface.

4 . The electronic apparatus as claimed in claim 3 , wherein said housing further includes a frame disposed between said first and second cover bodies and having said first and second ends of said housing, said frame defining a receiving space that receives said switch device, and having a first opening at said first end for communicating said receiving space with an outside environment, and a second opening at said second end for communicating said receiving space with the outside environment, said first contact point protruding through said first opening when said switch assembly is in said first position, said second contact point protruding through said second opening when said switch assembly is in said second position.

5 . The electronic apparatus as claimed in claim 3 , wherein said switch assembly includes a carrier and a switch disposed on said carrier, said carrier having said sliding portion and said first contact point, said switch including a pushbutton having said second contact point, and a spring to bias said pushbutton away from said first contact point for maintaining said switch assembly in said OFF state.

6 . The electronic apparatus as claimed in claim 5 , wherein said support member includes two retaining hooks disposed on two opposite sides of said abutment surface, each of said retaining hooks having an elongated guide arm portion, said sliding portion including two sliding blocks each of which defines an elongated sliding groove receiving said elongated guide arm portion of a respective one of said retaining hooks such that each of said sliding blocks is slidable relative to said elongated guide arm portion of the respective one of said retaining hooks, said elongated guide arm portions of said retaining hooks and said elongated sliding grooves of said sliding blocks being elongated in a direction parallel with said first and second directions.

7 . The electronic apparatus as claimed in claim 6 , wherein said at least one first end surface includes two said first end surfaces, each of said sliding blocks having a respective one of said first end surfaces, and a second end surface opposite to the respective one of said first end surfaces, said elongated sliding groove of each of said sliding blocks being formed between said second end surface and the respective one of said first end surfaces, said elongated guide arm portions of said retaining hooks respectively projecting from said two opposite sides of said abutment surface, each of said retaining hooks further having a hook end formed on a terminal end of a respective one of said elongated guide arm portions for abutting and stopping said second end surface to thereby position said switch assembly at said second position.

8 . The electronic apparatus as claimed in claim 7 , wherein said hook end of each of said retaining hooks has an inclined guide surface for abutting and guiding a respective one of said sliding blocks during mounting of said switch assembly on said support member.

9 . The electronic apparatus as claimed in claim 7 , wherein said support member defines a longitudinal axis, and includes a support base having said abutment surface, and an axially extending guide hole extending through said abutment surface, said carrier including a carrier body and a column, said carrier body including a base wall supporting said switch, and two positioning hooks, said sliding blocks being respectively formed on two opposite sides of said base wall, said positioning hooks respectively protruding from said second end surfaces of said sliding blocks and engaging said switch, said column projecting from said base wall opposite to said positioning hooks and having said first contact point, said column being inserted into said axially extending guide hole to extend said first contact point out of said support base.

10 . The electronic apparatus as claimed in claim 9 , wherein each of said positioning hooks includes a positioning arm portion protruding from said second end surface of a respective one of said sliding blocks, and a positioning hook end formed on a terminal end of said positioning arm portion and engaging said switch, said positioning hook end of each of said positioning hooks having an inclined surface for abutting and guiding said switch during mounting of said switch on said carrier.

11 . The electronic apparatus as claimed in claim 9 , wherein said carrier body further includes a first surrounding wall connected to said base wall and said sliding blocks, and a second surrounding wall connected to said sliding blocks opposite to said first surrounding wall and spaced apart from said base wall, wherein said base wall, said sliding blocks, and said first and second surrounding walls cooperatively define a receiving groove for receiving said switch, and wherein said base wall, said sliding blocks, and said second surrounding wall cooperatively define an opening communicating with said receiving groove, said switch further including a transmission line extending out of said receiving groove through said opening.

12 . A switch device of an electronic apparatus which includes opposite first and second cover bodies, said switch device comprising:
a support assembly including a support member; and a switch assembly mounted on and slidable relative to said support member and having a sliding portion slidably connected to said support member, a first contact point configured to be pushed by the first cover body, and a second contact point opposite to sai
