Electronic device and its fixing module capable of fastening a board

Abstract

A fixing module capable of fastening a board having an engaging portion includes a bracket, an extending component, and a fixing component. The bracket has a protrusion. The extending component is used for supporting the board in a first direction. The fixing component for holding the board with the extending component includes a baseboard, an elastic hook, and a sheath. The elastic hook includes an inclined structure, a first stopper, and a second stopper. The inclined structure is connected to the baseboard. The first stopper is connected to the inclined structure for holding the board with the extension component in the first direction. The second stopper is connected to the first stopper for constraining the board in a second direction. The sheath is connected to the baseboard for holding the protrusion.

1 . A fixing module capable of fastening a board having an engaging portion, the fixing module comprising:
 a bracket having a protrusion;   an extending component for supporting the board in a first direction; and   a fixing component for holding the board with the extending component, comprising:
 a baseboard; 
 an elastic hook comprising:
 an inclined structure connected to the baseboard; 
 a first stopper connected to the inclined structure for holding the board with the extending component in the first direction; and 
 a second stopper connected to the first stopper for constraining the board in a second direction; and 
 
 a sheath connected to the baseboard for holding the protrusion. 
   
   
   
       2 . The fixing module of  claim 1 , wherein the extending component is disposed at the protrusion. 
   
   
       3 . The fixing module of  claim 1 , wherein the extending component is disposed at the fixing component. 
   
   
       4 . The fixing module of  claim 1 , wherein the protrusion further has a hole and the fixing component further has a protruding piece connected to the baseboard to insert into the hole for fixing the fixing component on the protrusion. 
   
   
       5 . The fixing module of  claim 1 , wherein the fixing component is made of metal material. 
   
   
       6 . The fixing module of  claim 1 , wherein the baseboard and the elastic hook are monolithically formed. 
   
   
       7 . The fixing module of  claim 1 , wherein the sheath comprises two L-shaped baffles. 
   
   
       8 . The fixing module of  claim 1 , wherein the baseboard and the sheath are monolithically formed. 
   
   
       9 . The fixing module of  claim 1 , wherein the inclined structure, the first stopper, and the second stopper are monolithically formed. 
   
   
       10 . The fixing module of  claim 5 , wherein the board is a circuit board of an electronic device, and the second stopper is a ground terminal electrically contacting with the engaging portion of the circuit board. 
   
   
       11 . An electronic device comprising:
 a board having an engaging portion; and   a fixing module engaging with the engaging portion of the board, the fixing module comprising:
 a bracket having a protrusion; 
 an extending component disposed on the bracket, for supporting the board in a first direction; and 
 an elastic hook comprising:
 an inclined structure connected to the protrusion;
 a first stopper connected to the inclined structure for holding the board with the extending component in the first direction; and 
 a second stopper connected to the first stopper for constraining the board in a second direction; 
 
 
   wherein the engaging portion of the board is moved toward the bracket along the inclined structure until the board is fastened by the first stopper, the second stopper and the extending component.   
   
   
       12 . The electronic device of  claim 11 , wherein the extending component is disposed at the protrusion. 
   
   
       13 . The electronic device of  claim 11 , wherein the elastic hook is made of metal material. 
   
   
       14 . The electronic device of  claim 11 , wherein the protrusion and the elastic hook are monolithically formed. 
   
   
       15 . The electronic device of  claim 11 , wherein the inclined structure, the first stopper, and the second stopper are monolithically formed. 
   
   
       16 . The electronic device of  claim 13 , wherein the board is a circuit board, and the engaging portion has a conductive terminal contacting with the second stopper. 
   
   
       17 . The electronic device of  claim 13 , wherein the second stopper is a ground terminal.
