Embodiment
Below, by reference to the accompanying drawings, with reference to specific embodiment the present invention is described.In addition, the structure among the embodiment that the following describes only is an object lesson of enumerating in order to explain the present invention how to implement, and is not to be restriction to protection domain of the present invention, can carry out various distortion and change to embodiment in the scope of protection of the invention.In addition, the connected mode between the parts comprise be threaded, weld, the various ways such as riveted joint, can select as required, and these connected modes all are included within protection scope of the present invention.
Fig. 2, Fig. 3～Fig. 6 are the three-dimensional views of the structure of expression camera head of the present invention.Wherein, Fig. 4 is the three-dimensional view under the state that in the camera head of the present invention upper casing 2a is taken off.As shown in Figure 4, camera head of the present invention comprises that camera head main body 1 and casing 2 consist of.
According to Fig. 2 as seen, casing 2 comprises upper casing 2a and lower casing 2b, and casing 2 is to be made by metal material, has electric conductivity and firm other materials is made but also can have.In addition, in this example, casing 2 is designed to cylindric, still also can be set to as required the various shapes such as rectangular parallelepiped.
Camera head main body 1 comprises camera 11, lighting source 12 and control circuit (not shown).Control circuit in the camera head main body 1 partly is contained among the lower casing 2b.Camera 11 and lighting source 12 are outstanding from lower casing 2b, and are arranged on roughly on the same level face.
Specifically, as shown in Figure 3, shade 22 comprises shade 22a and lower shade 22b.The part that the internal perisporium up and down shade 22b of upper shade 22a engages is provided with internal thread and section be " T " font, namely go up among the shade 22a in ring with encircle outside direction be equipped with flange.The part that engages with upper shade 22a on the periphery wall of lower shade 22b is provided with external thread, and corresponding among the upper shade 22a to the flange of the outer direction of ring, establish equally the directed loop flange of direction outward.And the end face that lower shade 22b is relative with upper shade 22a be provided with upper shade 22a in the ring flange of direction corresponding, be used for placing the groove of central light-passing board 212.Like this, by threaded portion among the upper shade 22a being inserted in the opening in the peripheral light-passing board 211, and groove part is placed after the central light-passing board 212 therein, upper shade 22a is buckled on the lower shade 22b screws, thereby central light-passing board 212 is stuck between the groove of the flange of direction in the ring of shade 22a and lower shade 22b, and peripheral light-passing board 211 is stuck between shade 22a and the lower shade 22b flange of direction outside ring separately.Simultaneously, upper shade 22a and lower shade 22b also are fixed between peripheral light-passing board 211 and the central light-passing board 212, and do not contact with other parts of upper casing 2a.
Except said structure, light-passing board 21 also can be an entire plate, and shade 22 is connected on the light-passing board 21 by any mode such as bonding.
In addition, the material of shade 22 is preferably metal, also can be any material with electric conductivity.And, in this example, shade 22 is cylindric, but also can be the various shapes such as rectangle, and what of LED lamp quantity also can clip the partial sidewall of shade 22 according to, as long as be formed between camera 11 and the lighting source 12, can cover the light that lighting source 12 sends and its any light-blocking member such as shadow shield that enter camera 11 is got final product.Like this, can correspondingly save material and simplify technique.
The above has introduced casing 2 and has comprised upper casing 2a and lower casing 2b, and the structure of light-passing board 21 and shade 22 is set at upper casing 2a, but also can be the casing of taking one, and in the part perforate corresponding to camera 11 and lighting source 12, and the structure of light-passing board 21 and shade 22 is set in the hole.
Below, the ground structure of one embodiment of the present of invention is described in conjunction with Fig. 4～Fig. 7.As shown in Figure 6, this ground structure (conductive component) comprises discharge ring 3 and discharge sheet 4.Discharge ring 3 is fixed on the shade 22 by screw etc.Certainly, as long as can reach the effect of conduction, also can connect by the whole bag of tricks such as riveted joints.Discharge sheet 4 one ends are connected with lower casing 2b, and the other end contacts with discharge ring 3.Because lower casing 2b adopts the metal quality, and be connected with ground, thereby the electric charge of accumulation can be directed in the earth via discharging ring 3 and discharge sheet 4 and lower casing 2b on the shade 22.
As shown in Figure 4 and Figure 5, in order to keep the stable of sheet 4 that discharge, the sheet 4 that can will discharge in circuit board 122 and protective cover 13 junctions is together fixing.And, in order not affect the debugging to camera 11, also discharge sheet 4 can be bent into the shape of coincideing with protective cover 13, so that it is attached on the surface of protective cover 13.In addition, discharge sheet 4 also can via protective cover 13 being affixed to the screw of lower casing 2b and together being fixed on the lower casing 2b, also can be directly connected on the lower casing 2b.
As shown in Figure 7, in the present embodiment, discharge ring 3 comprises two parts, and the ring 3 that namely is used for discharge is fixed to the circular flange portion on the shade 22 and is used for the contact portion that contacts to discharge with the sheet 4 that discharges.This contact portion adopts reversed round bench shaped, and namely its diameter is from the junction of flange portion, along with extending and diminishing shape to the direction of discharge sheet 4.By adopting reversed round bench shaped, when upper casing 2a was assembled into lower casing 2b when upper towards the direction of lower casing 2b, along with approaching of upper casing 2a and lower casing 2b, the contact between discharge ring 3 and the discharge sheet 4 can become further tight, so also just can obtain better discharge effect.
As mentioned above, in order to save the reasons such as material, shade 22 is complete ring-type not necessarily, if shade 22 is jaggy, and upper and lower casing can encircle the 3 complete ring-types that are set to seal with discharge so by the screw thread rotation connection, whereby, can guarantee that after upper casing 2a and lower casing 2b assemble discharge sheet 4 can contact with discharge ring 3 all the time, guarantees the situation that discharge path can not occur disconnecting; And if upper and lower casing is to connect by the mode that hasp etc. can be located, the ring 3 that so not necessarily will discharge is set to closed circular, also can adopt the various shapes such as incomplete ring-type or sheet, in order to reach the purpose of saving material and simplifying technique.
In addition, those skilled in the art can understand, and also can omit discharge ring 3 and discharge sheet 4 contact with shade 22, and in this case, the part that also shade 22 and the sheet 4 that discharges can be contacted be processed as with above-mentioned discharge encircles 3 identical reversed round bench shapeds.Can further save material like this and simplify technique.
The above describes the present invention as an example of the security video camera example, but the present invention also can be applied to can discharge to the electric charge in this unsettled metal parts simply and effectively by the present invention in the equipment such as video camera that any beyond the security have unsettled metal parts.
