A kind of video camera
Technical field
The utility model belongs to picture pick-up device technical field, and in particular to a kind of video camera of the fixed PCB of no screw.
Background technique
Video camera, waterproof DV, camera type is various, and the basic principle of work is the same: light
It learns picture signal and is changed into electric signal, in order to store or transmit.When we shoot an object, reflected on this object
Light is collected by camera lens, focuses on it on light-receiving surface of picture pick-up device (such as target surface of pick-up tube), then pass through camera shooting
Light is changed into electric energy to get " vision signal " has been arrived by device.Photosignal is very faint, need to be amplified by pre-arcing road,
It is handled and is adjusted using various circuits, the standard signal finally obtained can be sent on the recording mediums such as video recorder and record
Get off, or propagates or be sent on monitor by broadcasting system and show.
Existing video camera main component includes: front cover, 3 ' of upper cover, 4 ' of rear cover, 8 ' of lower cover, 6 ' of the first pcb board, the 2nd PCB
1 ' of 7 ' of plate, 5 ' of screw and the first stud, 2 ' of the second stud, as shown in Figure 1, Sensor plate is born against on front cover admittedly when assembling, by
The fixed Sensor plate of four 1 ' of the first stud, while 7 ' of the second pcb board is supported, then fix the second pcb board by 42 ' of the second stud
7 ', while 6 ' of the first pcb board is supported, 6 ' of the first pcb board is fixed by 45 ' of screw, then 3 ' of upper cover and 4 ' of rear cover is installed.
Existing video camera scheme is by 1 ' of the first stud, 2 ' of the second stud, 5 ' of screw, and 4 screws of totally 8 studs are completed
It is more to fix material required for PCB for the fixation of PCB.It needs first to fix 41 ' of the first stud when assembly, then places the second pcb board
7 ', then 42 ' of the second stud are fixed, then place 6 ' of the first pcb board, then lock 45 ' of screw, assembling process is complicated.
Summary of the invention
To solve the above problem existing for present technology, the utility model provides that a kind of part is few, assembly is simple, fixed
Reliable video camera.
The technical solution adopted in the utility model is:
A kind of video camera, including shell are provided with fixed bracket in the shell, are fitted with PCB on the fixed bracket
Plate.The utility model inserts fixed pcb board using fixed bracket, and assembly is simple, and the part used is few.
Further, the shell includes upper cover, and the upper interior surface, which is provided with, is fixed on fixed bracket for pcb board pressing
On pressing part, by upper cover force in pressing part, by power conduction on pcb board, to press pcb board, there is pcb board
Effect is fixed.
Further, the pressing part is softer, elastic part, and the dress of pcb board is eliminated using the compressed capability of softer, elastic part
With gap.
Further, the softer, elastic part is foam, reduces pcb board and support bracket fastened gap using foam.
Further, the shell includes pedestal, and the fixed branch is set up on pedestal.
Further, the pedestal and fixed bracket are separate structure or integral structure.
Further, the fixed branch is provided with the card slot being oppositely arranged for the insertion of pcb board both ends, and card slot has a depthkeeping
Degree, support pcb board tilt it not.
Further, the outer edge of the card slot is equipped with guide bevel, facilitates the insertion of pcb board.
Further, the side inner wall of the card slot is equipped with the protrusion of positioning, moves left and right for reducing pcb board, and
Reduce gap.
Further, the lower part for the card slot being oppositely arranged is connected to by link slot and is connected.
The beneficial effects of the utility model are:
1, part is few, and only 2 parts just complete the fixation of pcb board.
2, assembly is simple, can fix pcb board by inserting pressing.

Specific embodiment
Combined with specific embodiments below the utility model to be further described, but the utility model is not limited to
In these specific embodiments.One skilled in the art would recognize that the utility model covers in Claims scope
All alternatives, improvement project and the equivalent scheme that may include.
Embodiment one
Referring to Fig. 2-4, video camera provided in this embodiment, including shell, shell include front cover (being not marked in figure), upper cover
2, pedestal 7, rear cover 3, Sensor plate are individually fixed on front cover, and fixed bracket 6, the fixed branch are provided on the pedestal 7
Pcb board 4 and 5 is fitted on frame 6, the upper cover 2 is transparence display, and inner surface, which is provided with, is fixed on the pressing of pcb board 4 and 5
Pressing part on fixed bracket 6.The utility model inserts fixed pcb board 4 and 5 using fixed bracket 6, then is exerted a force by upper cover 2
In pressing part 1, through power conduction on pcb board 4 and 5, to press pcb board 4 and 5, keep pcb board 4 and 5 effectively fixed, dress
With simple, and the part used is few.
Pressing part described in the present embodiment is softer, elastic part, eliminates pcb board using the compressed capability of softer, elastic part
Fit-up gap.The preferred foam 1 of softer, elastic part reduces pcb board and support bracket fastened gap using foam 1.Foam 1 can be placed
On pcb board 4 and 5, upper cover 2 is then assembled.Also it can use gum and foam 1 be affixed on 2 inner surface of upper cover, then close again
Lid.Foam 1 is fixed among upper cover 2 and pcb board 4 and 5, and foam 1 has certain decrement d after assembly, referring to Fig. 5.
The support portion that bracket 6 is symmetrically arranged with protrusion is fixed described in the present embodiment, support portion is equipped with and is inserted into for pcb board 4 or 5
Card slot 60, card slot 60 have certain depth, and support pcb board 4 and 5 tilts it not, referring to Fig. 6, Fig. 7.Outside the card slot 60
Edge is equipped with guide bevel 40, facilitates the insertion of pcb board 4 and 5.The side inner wall of the card slot 60 is equipped with the protrusion of positioning
50, it referring to Fig. 8, is moved left and right for reducing pcb board 4 and 5, and reduce gap.The card slot 60 is set to the two of pcb board 4 and 5
End, fixed the bracket 6 ipsilateral number of card slot 60 and the quantity of pcb board are consistent, and see Fig. 9.
Pedestal 7 described in the present embodiment and fixed bracket 6 are separate structures, i.e., fixed bracket is an individual part,
It can be integral structure with pedestal 7 and fixed bracket 6, i.e., directly slot on pedestal 7.
When the utility model assembles, the both ends of pcb board 4 and 5 are inserted into the card slot 60 of fixed bracket 6 being oppositely arranged respectively
It is interior, pcb board 4 and 5 is pre-fixed, the gap of pcb board 4 and 5 and fixed bracket 6 is reduced using foam 1, it is complete using upper cover 2
