Joystick Controller

Abstract

A joystick controller includes a printed circuit board defining a plurality of pads thereon, a restraining assembly fastened above the printed circuit board, a switch button slidably mounted onto the restraining assembly with a locking post stretching into the restraining assembly, and a connecting member slidably mounted between the restraining assembly and the printed circuit board and further restrained by the restraining assembly. The connecting member has a base board, a plurality of contact portions protruded under the base board, and a locking axle protruded on the base board. The locking axle is inserted into the restraining assembly and then locked to a bottom end of the locking post so that the connecting member can be driven to slide in a restrained range by the restraining assembly through smoothly pushing the switch button so as to make the contact portions electrically contact the corresponding pads of the printed circuit board.

1 . A joystick controller, comprising:
 a printed circuit board defining a plurality of pads thereon spaced from one another;   a restraining assembly fastened above the printed circuit board;   a switch button slidably mounted onto the restraining assembly with a locking post stretching into the restraining assembly; and   a connecting member slidably mounted between the restraining assembly and the printed circuit board and further restrained by the restraining assembly, the connecting member having a base board, a plurality of contact portions protruded under the base board and spaced from one another, and a locking axle protruded on the base board, the locking axle being inserted into the restraining assembly and then locked to a bottom end of the locking post of the switch button so that the connecting member can be driven to slide in a restrained range by the restraining assembly through smoothly pushing the switch button so as to make the contact portions electrically contact the corresponding pads of the printed circuit board.   
     
     
         2 . The joystick controller as claimed in  claim 1 , wherein the contact portions have four uniformly arranged into a circle, and the pads are designated as four pairs uniformly arranged into a circle, when adjacent or opposite two of the contact portions contact corresponding adjacent or relative two of the pads, the other two adjacent or opposite contact portions will not contact another two adjacent or relative pads. 
     
     
         3 . The joystick controller as claimed in  claim 1 , wherein a peripheral edge of the base board of the connecting member uniformly protrudes outward to form a plurality of connecting arms symmetrically arranged and spaced from one another, each of the contact portions is protruded under one corresponding connecting arm. 
     
     
         4 . The joystick controller as claimed in  claim 1 , wherein the bottom end of the locking post of the switch button defines a locking structure which includes a polygonal locking cavity opened in a bottom end surface of the locking post and a plurality of locking fillisters opened in inner walls of the locking cavity, the locking axle of the connecting member has a polygonal cross-section and each corner of a top end thereof is cut away to form a buckling corner, the top end of the locking axle is locked in the locking cavity of the locking post and the buckling corners are buckled in the corresponding locking fillisters. 
     
     
         5 . The joystick controller as claimed in  claim 1 , wherein the switch button includes a top board, a bottom board parallel to and spaced from the top board, and a connecting pillar connected between the top board and the bottom board, the locking post is protruded oppositely to the connecting pillar under the bottom board, the bottom board is slidably disposed on the restraining assembly. 
     
     
         6 . The joystick controller as claimed in  claim 1 , wherein the restraining assembly includes a shell, a restraining body and two slide members, the shell has a top plate with a hole opened therein, a plurality of side plates are extended downward from peripheral edges of the top plate and connected with one another to define a receiving chamber thereamong, the restraining body is fastened in the receiving chamber of the shell and defines a square restraining cavity in a bottom surface thereof and a guiding window in a top surface thereof which communicates with a middle of the restraining cavity and further faces the hole of the shell, each of the slide members is of rectangular shape with a slide chute opened therein along a longwise direction thereof, the length of the slide member is equal to the side length of the restraining cavity, the two slide members are perpendicularly and slidably disposed in the restraining cavity of the restraining body with overlapped parts of the two slide chutes facing the guiding window, the locking post of the switch button passes through the hole to stretch into the receiving chamber, and the locking axle of the connecting member successively passes upward through the overlapped parts of the two slide chutes and the guiding window to be locked to the bottom end of the locking post. 
     
     
         7 . The joystick controller as claimed in  claim 6 , wherein the locking axle of the connecting member has a square cross-section with the same side length as the width of the slide chute of the slide member so as to make the locking axle just slide under restraining of the slide chutes and the guiding window but not rotate. 
     
     
         8 . The joystick controller as claimed in  claim 6 , wherein the restraining assembly further includes an elastic component which is clipped between the restraining body and the top plate of the shell and further worn around the locking post of the switch button against the side plates so as to provide a repositioning elastic force for the switch button. 
     
     
         9 . The joystick controller as claimed in  claim 8 , wherein the elastic component is a spring of Archimedes spiral shape.
