## Abstract

A fixing apparatus for holding a circuit board in place includes a cover plate, a base for supporting the circuit board thereon, a connecting assembly for hinge-coupling a first end of the cover plate to the base, and a latching assembly for latching a second end of the cover plate to the base. The circuit board is held in place between the base and the cover plate.

## Claims

### Claim 1

A fixing apparatus for holding a circuit board in place, the fixing apparatus comprising:
a cover plate comprising a first end and a second end;
a base configured to support the circuit board thereon;
a connecting assembly configured to hinge-couple the first end of the cover plate to the base; and
a latching assembly configured to latch the second end of the cover plate to the base, so as to hold the circuit board in place between the base and the cover plate;
wherein the connecting assembly comprises a protrusion extending from each opposite side of the connecting assembly, the first end of the cover plate is coupled between the protrusions and hinge-coupled to the base.

### Claim 2 (depends on 1)

The fixing apparatus of claim 1, wherein a surface of the cover plate facing the base defines a recess for accommodating the circuit board.

### Claim 3 (depends on 1)

The fixing apparatus of claim 1, wherein:
the base is hollow and comprises a main body; the first end of the cover plate is coupled to the main body by the connecting assembly;
the second end of the cover plate is coupled to the main body by the latching assembly;
the connecting assembly and the latching assembly are located at opposite sides of the main body.

### Claim 4 (depends on 3)

The fixing apparatus of claim 3, wherein:
the main body comprises a top plate, a peripheral wall, and a bottom plate;
the peripheral wall surrounds a periphery of the top plate;
a cavity is defined by the peripheral wall;
the bottom plate covers the cavity.

### Claim 5 (depends on 4)

The fixing apparatus of claim 4, wherein the main body comprises a sealing member arranged between the peripheral wall and the bottom plate to seal any gaps between the peripheral wall and the bottom plate.

### Claim 6 (depends on 4)

The fixing apparatus of claim 4, wherein a first through hole is defined in the top plate; the first through hole communicates with the cavity.

### Claim 7 (depends on 6)

The fixing apparatus of claim 6, wherein the main body comprises a cushion member; a mounting recess is defined in the top plate; the cushion member is received in the mounting recess.

### Claim 8 (depends on 7)

The fixing apparatus of claim 7, wherein the cushion member defines a second through hole corresponding in position with the first through hole such that the second through hole communicates with the cavity.

### Claim 9 (depends on 4)

The fixing apparatus of claim 4, wherein a connecting hole is defined in the bottom plate; the connecting hole passes through the bottom plate and communicates with the cavity.

### Claim 10 (depends on 4)

The fixing apparatus of claim 4, wherein a bottom surface of the bottom plate comprises a plurality of supporting legs for supporting the bottom plate.

### Claim 11 (depends on 1)

The fixing apparatus of claim 1, wherein:
the latching assembly comprises a limiting portion and a latching portion;
the limiting portion fixes the latching assembly to the base;
the limiting portion comprises two extending portions extending from opposite sides of the limiting portion;
the latching portion is located between the two extending portions; the latching portion latches the second end of the cover plate.
