Description

카메라 조립체{A camera assembbly}Camera assembly {A camera assembbly}

본 고안은 카메라 조립체에 관한 것으로써, 특히 외부진동이나 충격에도 불구하고 렌즈의 조립위치를 유지시키고 방수기능을 저하를 방지할 수 있도록 한 카메라 조립체에 관한 것이다.The present invention relates to a camera assembly, and more particularly, to a camera assembly capable of maintaining the assembly position of the lens in spite of external vibration or shock and preventing the degradation of the waterproof function.

일반적으로 감시용 카메라, 차량용 카메라와 같은 카메라 조립체들은 도 1 및 도 2에 도시된 바와 같이, 일측에 렌즈(11)를 고정하는 렌즈홀더(10)와, 렌즈홀더(10)의 타측에 고정되는 회로기판(20)과, 외부로부터 전원선이 유입되며 외주면에 수나사(31)가 형성된 엔드블럭(30)과, 통형으로서 일단부 내주면에 상기 수나사(31)에 나사결합되는 암나사(41)가 형성되고 타단부에 상기 렌즈(11)를 노출시키는 구멍(42)이 형성된 케이스(40)로 이루어진다.In general, camera assemblies such as surveillance cameras and vehicle cameras are fixed to the lens holder 10 and the other side of the lens holder 10 to secure the lens 11 to one side, as shown in Figure 1 and 2 A circuit board 20, an end block 30 having a male thread 31 formed on an outer circumferential surface of the power supply line from the outside, and a female thread 41 screwed to the male thread 31 on an inner circumferential surface of one end in a cylindrical shape are formed. And a case 40 having a hole 42 for exposing the lens 11 at the other end thereof.

또한, 상기 카메라 조립체는 오링(51)(52)들에 의해서 케이스(40) 내부가 방수될 수 있도록 하고 있다.In addition, the camera assembly allows the inside of the case 40 to be waterproofed by the O-rings 51 and 52.

상기와 같은 카메라 조립체는 소형화를 위하여 회로기판(20)을 수평 및 직립형으로 제작하여 가늘고 긴 형상으로 제작된다.The camera assembly as described above is manufactured in a thin and elongated shape by making the circuit board 20 horizontal and upright for miniaturization.

이와 같은 카메라 조립체는 엔드블럭(30)이나 케이스(40)가 고정체(미도시)에 고정되어 사용되어지는데, 렌즈홀더(10), 렌즈(11) 및 회로기판(20)이 케이스(40) 내부에 별도의 고정수단없이 단순히 수용되는 구조를 가짐으로써 외부진동 또는 충격이(예컨대, 차량용으로 사용되는 경우) 발생되는 경우 렌즈(11)의 센터위치가 변경되어서 초점조절이나 렌즈(11)의 위치를 조정하여야 하는 번거로움이 발생하게 된다.Such a camera assembly is used in which the end block 30 or the case 40 is fixed to a fixed body (not shown), and the lens holder 10, the lens 11, and the circuit board 20 are the case 40. By having a structure that is simply accommodated without a separate fixing means therein, when external vibration or shock is generated (for example, when used for a vehicle), the center position of the lens 11 is changed to adjust the focus or the position of the lens 11. The hassle to adjust is caused.

또한, 방수를 위한 오링(52)이 설치되어 있음에도 불구하고, 상기와 같이 렌즈(11)의 위치가 진동이나 충격에 의해 변위될때 오링(52)과의 틈새가 발생되어 방수기능이 떨어지게 된다.In addition, even though the O-ring 52 for waterproofing is installed, when the position of the lens 11 is displaced by vibration or shock as described above, a gap with the O-ring 52 is generated, thereby deteriorating the waterproofing function.

본 고안은 상기와 같은 문제점을 해결하기 위한 것으로써, 외부의 진동이나 충격이 발생되더라도 케이스에 대하여 렌즈의 위치가 변위되는 것을 방지할 수 있도록 한 카메라 조립체를 제공하는 데 목적이 있다.The present invention is to solve the above problems, it is an object to provide a camera assembly that can prevent the position of the lens with respect to the case even if the external vibration or shock occurs.

상기 목적을 달성하는 본 고안 카메라 조립체는 각각 외주면에 수나사가 형성된 제1결합부와 제2결합부를 구비하고, 제2결합부의 단부에 렌즈가 고정되는 렌즈홀더와;The camera assembly of the present invention to achieve the above object comprises a lens holder having a first coupling portion and a second coupling portion, each of which has a male screw formed on an outer circumferential surface thereof, and a lens is fixed to an end of the second coupling portion;

상기 제1결합부의 단부에 고정되는 회로기판과;A circuit board fixed to an end of the first coupling part;

일단을 통하여 외부로부터 전원선이 유입되고 타단부 내면에 상기 제1결합부에 나사결합되는 암나사가 형성되며 상기 회로기판을 수용하는 케이스와;A case in which a power line is introduced from the outside through one end and a female screw screwed to the first coupling part is formed at an inner surface of the other end to accommodate the circuit board;

일단부 내면에 상기 제2결합부에 나사결합되는 암나사가 형성되고, 타단부에 투명한 윈도우가 결합된 엔드캡;을 구비한 것을 특징으로 한다.And an end cap having a female screw screwed to the second coupling part at an inner surface of one end thereof and having a transparent window coupled to the other end thereof.

본 고안 카메라 조립체는 외부진동이나 충격에도 불구하고 렌즈홀더(60)가 케이스(80) 및 엔드캡(90)에 대하여 상대유동되지 아니하고 함께 유동되게 되므로 렌즈의 변위를 방지할 수 있게 된다.The camera assembly of the present invention can prevent displacement of the lens because the lens holder 60 is flowed together with respect to the case 80 and the end cap 90 in spite of external vibration or impact.

또한, 렌즈홀더(60)에 케이스(80)와 엔드캡(90)이 모두 나사결합되어 일체로 유동하는 구조를 가짐으로써, 오링(101)(102)에 의한 방수기능을 유지할 수 있도록 한다.In addition, both the case 80 and the end cap 90 are screwed to the lens holder 60 to have a structure that flows integrally, thereby maintaining the waterproof function by the O-rings 101 and 102.

도 1 및 도 2는 종래 카메라 조립체를 나타낸 분리도 및 결합단면도,
도 3 및 도 4는 본 고안 실시예의 카메라 조립체를 나타낸 분리도 및 결합단면도.1 and 2 is an exploded view and a cross-sectional view showing a conventional camera assembly,
3 and 4 is an exploded view and a cross-sectional view showing a camera assembly of the present invention embodiment.

본 고안 실시예의 카메라 조립체는 예컨대, 건물이나 차량에 설치하여 이용하는 도중에 진동이나 충격이 가해지는 경우에도 렌즈의 위치가 변위되는 것을 방지하여, 추후 렌즈의 위치조정을 불필요하게 한다. 또한, 렌즈의 설치상태를 유지하여 오링등에 의한 방수기능의 저하를 방지할 수 있도록 한다.The camera assembly according to the embodiment of the present invention, for example, prevents the lens from being displaced even when vibration or shock is applied during installation and use in a building or a vehicle, thereby making it unnecessary to adjust the position of the lens later. In addition, it is possible to prevent the degradation of the waterproof function by the O-ring, etc. by maintaining the installation state of the lens.

본 고안 실시예의 카메라 조립체를 나타낸 도 3 및 도 4를 참조하면, 이는 각각 외주면에 수나사가 형성된 제1결합부(61)와 제2결합부(62)를 구비하고, 제2결합부(62)의 단부에 렌즈(100)가 고정되는 렌즈홀더(60)와; 상기 제1결합부(61)의 단부에 고정되는 회로기판(70)과; 일단을 통하여 외부로부터 전원선이 유입되고 타단부 내면에 상기 제1결합부(61)에 나사결합되는 암나사(81)가 형성되며 상기 회로기판(70)을 수용하는 케이스(80)와; 일단부 내면에 상기 제2결합부(62)에 나사결합되는 암나사(91)가 형성되고, 타단부에 투명한 윈도우(92)가 결합된 엔드캡(90);을 구비한다.3 and 4 showing the camera assembly of the present invention, each having a first coupling portion 61 and a second coupling portion 62 having male threads formed on the outer circumferential surface thereof, and the second coupling portion 62. A lens holder 60 to which the lens 100 is fixed at an end of the lens holder; A circuit board 70 fixed to an end of the first coupling part 61; A case (80) for receiving the circuit board (70) formed with a female screw (81) screwed into the first coupling part (61) on an inner surface of the other end through which a power line is introduced from the outside; An end cap 90 having a female screw 91 screwed to the second coupling portion 62 at one end of the inner surface and having a transparent window 92 coupled to the other end thereof.

또한, 상기 제1결합부(61)와 케이스(80) 사이에는 제1오링(101)이 위치되고, 제2결합부(62)와 엔드캡(90) 사이에는 제2오링(102)이 위치되어서, 회로기판(70)과 렌즈(100)를 각각 별도로 방수할 수 있도록 하였다.In addition, a first O-ring 101 is positioned between the first coupling portion 61 and the case 80, and a second O-ring 102 is positioned between the second coupling portion 62 and the end cap 90. Thus, the circuit board 70 and the lens 100 can be separately waterproofed.

상기와 같은 구성의 카메라 조립체는 케이스(80)가 외부 고정체(미도시)에 고정되어 사용되어지게 되는데, 렌즈홀더(60)가 케이스(80)에 나사결합되는 구조를 가짐으로써 외부 진동이나 충격이 가해지더라도 케이스(80)와 렌즈홀더(60)가 함께 유동되게 되므로 렌즈(100)의 위치가 케이스(80)에 대하여 변위(變位)되지 않게 된다.In the camera assembly having the above configuration, the case 80 is used to be fixed to an external fixing body (not shown). The lens holder 60 has a structure in which the lens holder 60 is screwed to the case 80 so that external vibration or shock may occur. Even if this is applied, since the case 80 and the lens holder 60 are flowed together, the position of the lens 100 is not displaced with respect to the case 80.

이에 따라서 종래에서와 같이 렌즈홀더(10), 렌즈(11) 및 회로기판(20)이 케이스(40) 내부에 별도의 고정수단없이 단순히 수용되는 구조를 가짐으로써 외부진동 또는 충격이(예컨대, 차량용으로 사용되는 경우) 발생되는 경우 렌즈(11)의 센터위치가 변경되어서 추후 초점조절이나 렌즈(11)의 위치를 조정하여야 하는 번거로움이 발생하였던 것과는 달리, 본 고안 카메라 조립체는 외부진동이나 충격에도 불구하고 렌즈홀더(60)가 케이스(80) 및 엔드캡(90)에 대하여 상대유동되지 아니하고 함께 유동되게 되므로 렌즈의 변위를 방지할 수 있게 된다.Accordingly, the lens holder 10, the lens 11, and the circuit board 20, as in the prior art, have a structure in which the housing 40 is simply accommodated without a separate fixing means, thereby preventing external vibration or shock (for example, for a vehicle). Unlike the case where the center position of the lens 11 is changed to cause a hassle to adjust the focus or the position of the lens 11 later, the camera assembly of the present invention may be subjected to external vibration or impact. Nevertheless, the lens holder 60 does not flow relative to the case 80 and the end cap 90, but flows together, thereby preventing displacement of the lens.

또한, 렌즈홀더(60)에 케이스(80)와 엔드캡(90)이 모두 나사결합되어 일체로 유동하는 구조를 가짐으로써, 오링(101)(102)에 의한 방수기능을 유지할 수 있도록 한다.In addition, both the case 80 and the end cap 90 are screwed to the lens holder 60 to have a structure that flows integrally, thereby maintaining the waterproof function by the O-rings 101 and 102.
