Description

현상기의 전원인가용 단자구조{STRUCTURE OF TERMINALS FOR DEVELEPING MACHINE}Terminal structure for power supply of developing device {STRUCTURE OF TERMINALS FOR DEVELEPING MACHINE}

본 발명은 현상기의 전원인가용 단자구조에 관한 것으로서, 특히, 레이저프린터나 복사기등과 같은 전자사진 인쇄방식의 화상형성장치의 현상기에 고전압을 인가시키는 단자들의 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal structure for applying power to a developing device, and more particularly, to a structure of terminals for applying a high voltage to a developing device of an electrophotographic printing type image forming apparatus such as a laser printer or a copying machine.

레이저프린터에는 예를 들어, 감광드럼에 형성된 정전잠상을 토너화상으로 현상하는 현상기가 내장된다. 현상기는 현상실과 토너수용실이 구획형성된 케이싱본체를 가진다. 현상실내에는 외주면에 도전성재료의 감광층이 형성된 감광드럼, 감광드럼을 대전시키는 대전장치, 감광드럼에 정전잠상이 형성되도록 레이저빔을 조사하는 노광장치, 및 토너수용실내의 토너를 감광드럼에 옮겨주는 복수의 현상롤러들이 설치되어 있다.The laser printer includes, for example, a developer for developing an electrostatic latent image formed on the photosensitive drum into a toner image. The developing unit has a casing body in which a developing chamber and a toner accommodating chamber are partitioned. In the developing chamber, a photosensitive drum having a photosensitive layer of conductive material formed on an outer circumferential surface thereof, a charging device for charging the photosensitive drum, an exposure apparatus for irradiating a laser beam to form an electrostatic latent image on the photosensitive drum, and a toner in the toner storage chamber are transferred to the photosensitive drum. The state is provided with a plurality of developing rollers.

도 1은 현상기가 화상형성장치의 케이싱에서 분리되어, 종래의 현상기의 전원인가용 단자들이 접속해제된 상태의 개략적 부분단면도이다. 종래의 현상기(10)의 전원인가용 단자구조(20)는, 도면에서 볼 수 있는 있는 바와 같이, 화상형성장치의 케이싱(1)에 설치되는 고정단자(31)와 현상기(10)에 마련되어 고정단자(31)와 통전가능한 접속단자(21)를 포함한다. 화상형성장치의 케이싱(1)에는 현상기(10)를 향해 개구된 단자홈(3)이 형성되어 있다.1 is a schematic partial cross-sectional view of a state in which a developing device is separated from a casing of an image forming apparatus, and power supply terminals of a conventional developing device are disconnected. The power supply terminal structure 20 of the conventional developing device 10 is fixed to the fixed terminal 31 and the developing device 10 provided in the casing 1 of the image forming apparatus, as shown in the drawing. And a connecting terminal 21 that can conduct electricity with the terminal 31. The casing 1 of the image forming apparatus is formed with a terminal groove 3 opened toward the developing device 10.

고정단자(31)는 현상기(10)의 접속단자(21)에 접속되는 머리부(33), 이 머리부(33)의 하측 단부로부터 반경방향으로 외향 연장된 걸림리브(35), 그리고, 걸림리브(35)를 중심으로 머리부(33)에 대향하는 방향으로 돌출된 스프링고정돌기(37)로 구분가능하다. 머리부(33)는 케이싱(1)의 외측방에서 단자홈(3)을 통과하여 현상기(10)를 향해 노출된다. 걸림리브(35)는 단자홈(3)의 반경보다 큰 반경을 가지며, 이에 의해, 고정단자(31)가 단자홈(3)을 완전히 통과하는 것이 방지된다.The fixed terminal 31 includes a head portion 33 connected to the connection terminal 21 of the developing device 10, a locking rib 35 extending outwardly in a radial direction from a lower end of the head portion 33, and a locking portion. It is possible to distinguish the spring fixing protrusions 37 protruding in the direction opposite to the head portion 33 with respect to the rib 35. The head 33 passes through the terminal groove 3 in the outer side of the casing 1 and is exposed toward the developing device 10. The locking rib 35 has a radius larger than the radius of the terminal groove 3, whereby the fixed terminal 31 is prevented from completely passing through the terminal groove 3.

이러한 고정단자(31)가 결합된 단자홈(3)의 후방에는 단자수용브라켓(50)이 착탈가능하게 고정된다. 단자수용브라켓(50)과 케이싱(1)의 결합구조는, 도면에 도시된 바와 같이, 단자수용브라켓(50)의 개구연으로부터 외향 연장된 플랜지부(51)와 케이싱(1)에 설치된 결합리브(5)로 간단히 구성가능하다. 그리고, 단자수용브라켓(50)내에는 탄성스프링(55)이 내장되어, 고정단자(31)의 스프링고정돌기(37)에 끼워져 있다. 탄성스프링(55)은 고정단자(31)를 탄성적으로 가압하여, 그 머리부(33)가 단자홈(3)을 통해 현상기(10)를 향해 노출되게 한다.The terminal receiving bracket 50 is detachably fixed to the rear of the terminal groove 3 to which the fixed terminal 31 is coupled. The coupling structure of the terminal accommodation bracket 50 and the casing 1 is, as shown in the drawing, a coupling rib provided in the flange portion 51 and the casing 1 extending outward from the opening edge of the terminal accommodation bracket 50. It is simply configurable as (5). In addition, an elastic spring 55 is built into the terminal receiving bracket 50 and fitted into the spring fixing protrusion 37 of the fixed terminal 31. The elastic spring 55 elastically presses the fixed terminal 31, so that the head 33 is exposed toward the developing device 10 through the terminal groove (3).

이와 같은 구성에 의하여, 화상형성장치의 케이싱(1)내에 현상기(10)를 장착시키면, 그 장착위치에서 자연스럽게 고정단자(31)와 접속단자(21)가 상호 접촉한다. 이러한 상태에서 기기의 작동이 개시되면, 도시않은 고압전원장치에서 발생되는 고전압이 고정단자(31)와 접속단자(21)를 통해 현상기(10)의 각 기능부분에 인가된다. 따라서, 현상기(10)는 인가되는 고전압을 사용하여, 감광드럼에 형성된 정전잠상을 토너화상으로 현상하는 그 본연의 임무를 수행할 수 있는 것이다.With this arrangement, when the developing device 10 is mounted in the casing 1 of the image forming apparatus, the fixed terminal 31 and the connecting terminal 21 naturally contact each other at the mounting position. When the operation of the device is started in such a state, the high voltage generated in the high voltage power supply device (not shown) is applied to each functional part of the developing device 10 through the fixed terminal 31 and the connection terminal 21. Therefore, the developing device 10 can perform its original task of developing the electrostatic latent image formed on the photosensitive drum into a toner image by using the high voltage applied thereto.

그런데, 이러한 종래의 현상기의 전원인가용 단자구조(20)에서는, 현상기(10)의 접속단자(21)와 접속되는 고정단자(31)가 단지 탄성스프링(55)의 탄성력에 의존하여 위치고정적으로 지지되므로, 예를 들어, 탄성스프링(55)의 탄성력이 규정치를 벗어나는 경우 혹은 시간이 경과하면서 그 탄성력이 약해지거나 불균일한 경우에, 접속단자(21)와 고정단자(31)간의 접속불량이 발생할 수 있는 염려가있다.By the way, in the conventional terminal structure 20 for power supply of the developing device, the fixed terminal 31 connected with the connecting terminal 21 of the developing device 10 is fixed in position only in dependence on the elastic force of the elastic spring 55. Since it is supported, for example, when the elastic force of the elastic spring 55 deviates from a prescribed value or when the elastic force becomes weak or uneven over time, a poor connection between the connection terminal 21 and the fixed terminal 31 may occur. There is concern.

종래의 현상기의 전원인가용 단자구조(20)에서는 특히, 케이싱(1)의 고정단자(31)와 현상기(10)의 접속단자(21)의 상호 접촉면적이 작기 때문에 이러한 접속불량이 발생할 우려가 더욱 크고, 또한, 상호 접촉부분에 이물질등이 개재되는 경우 전원공급이 제대로 이루어지지 않아서, 현상기(10)의 화상이 일그러지는등 중대한 문제를 야기시킬 수 있다.In the conventional terminal structure 20 for power supply of the developing device, in particular, since the contact area between the fixed terminal 31 of the casing 1 and the connecting terminal 21 of the developing device 10 is small, such connection failure may occur. In addition, when a foreign material or the like is interposed in the mutual contact portion, power supply is not properly performed, which may cause serious problems such as distortion of the image of the developing device 10.

따라서, 본 발명의 목적은 종래의 이러한 문제점을 고려하여, 탄성스프링의 탄성력이 규정치를 벗어나거나 혹은 시간이 경과하면서 그 탄성력이 약해지거나 불균일해지는 경우에도 현상기의 접속단자와 케이싱의 고정단자가 양호한 접속상태를 유지할 수 있도록 한 현상기의 전원인가용 단자구조를 제공하는 것이다.Accordingly, an object of the present invention is to consider such a problem in the prior art, and even if the elastic force of the elastic spring is out of the specified value or the elastic force becomes weak or uneven with time, the connection of the developing terminal and the fixed terminal of the casing are good. It is to provide a terminal structure for supplying power to a developer to maintain a state.

본 발명의 또 다른 목적은, 케이싱의 고정단자와 현상기의 접속단자 사이의 접촉면적을 최대한 넓혀 접속불량이 발생할 우려를 대폭 줄인 현상기의 전원인가용 단자구조를 제공하는 것이다.It is still another object of the present invention to provide a terminal structure for supplying power to a developer in which the contact area between the fixed terminal of the casing and the connection terminal of the developer is maximized to greatly reduce the possibility of connection failure.

본 발명의 또 다른 목적은, 케이싱의 고정단자와 현상기의 접속단자 사이에 이물질이 개재되더라도 그 통전상태를 양호하게 유지할 수 있도록 한 현상기의 전원인가용 단자구조를 제공하는 것이다.Still another object of the present invention is to provide a terminal structure for applying power to a developing device capable of maintaining a good energization state even when foreign matter is interposed between the fixed terminal of the casing and the connecting terminal of the developing device.

상기 목적은, 본 발명에 따른 화상형성장치의 케이싱내에 장착되는 현상기에 고전압을 인가시키는 단자구조에 있어서, 상기 케이싱에 마련된 단자수용부내에 수용되어 상기 현상기를 향해 개구된 단자홈을 통해 부분적으로 노출가능한 고정단자; 상기 단자수용부내에서 상기 고정단자를 탄성적으로 가압하는 탄성스프링; 및 상기 현상기에 설치되어 상기 고정단자와 통전가능하며, 상기 고정단자의 노출단부와의 접촉면에 결합홈이 형성되어 있는 접속단자를 포함하여 구성된 현상기의 전원인가용 단자구조에 의하여 달성된다.The object of the present invention is to provide a terminal structure for applying a high voltage to a developing device mounted in a casing of an image forming apparatus according to the present invention, wherein the terminal is partially exposed through a terminal groove accommodated in a terminal accommodating portion provided in the casing and opened toward the developing device. Possible fixed terminals; An elastic spring for elastically pressing the fixed terminal in the terminal accommodating portion; And a connection terminal installed in the developing unit, capable of conducting electricity to the fixed terminal, and including a connecting terminal having a coupling groove formed on a contact surface with the exposed end of the fixed terminal.

여기서, 상기 접속단자의 결합홈은 상기 접촉면에 대하여 반구형상으로 함몰되게 형성하는 것이 바람직하다.Here, the coupling groove of the connection terminal is preferably formed to be recessed in a hemispherical shape with respect to the contact surface.

그리고, 상기 결합홈에는 반경방향으로 외향 함몰된 이물질수집홈을 형성하는 것이 더욱 바람직하다.Further, it is more preferable to form the foreign matter collecting groove recessed outward in the radial direction in the coupling groove.

이하에서는, 첨부된 도면들을 참조하여 본 발명에 따른 현상기의 전원인가용 단자구조를 구체적으로 설명한다. 여기서, 화상형성장치의 케이싱 및 현상기에 대한 설명은 종래의 도 1과 관련하여 생략하고, 또한, 도 1과 관련하여 설명한 동일 구성 및 명칭에 대해서는 동일한 참조번호를 부여한다.Hereinafter, with reference to the accompanying drawings will be described in detail the terminal structure for applying power to the developer according to the present invention. Here, the description of the casing and the developing device of the image forming apparatus will be omitted in connection with the conventional FIG. 1, and the same reference numerals are assigned to the same configurations and names described with reference to FIG.

도 2는 본 발명에 따른 현상기의 전원인가용 단자들이 접속해제된 상태를 확대하여 부분단면도로서 나타낸 도면이고, 도 3은 도 2의 결합 횡단면도이다. 본 현상기의 전원인가용 단자구조(60)는, 종래의 도 1과 관련하여 설명한 바와 마찬가지로, 화상형성장치의 케이싱(1)에 설치되는 고정단자(31)와 현상기(10)에 마련되어 고정단자(31)와 통전가능한 접속단자(61)를 포함한다.2 is an enlarged view showing a partially disconnected state in which the power supply terminals of the developing device according to the present invention are disconnected, and FIG. 3 is a cross sectional view of FIG. The power supply terminal structure 60 of the present developer is provided in the fixed terminal 31 and the developing device 10 provided in the casing 1 of the image forming apparatus, as described with reference to FIG. 31) and a connecting terminal 61 capable of conducting electricity.

화상형성장치의 케이싱(1), 케이싱(1)의 단자홈(3)에 결합되는 고정단자(31), 및 고정단자(31)의 후방에 결합되는 단자수용브라켓(50)의 구성은종래와 동일하며, 이에 대한 설명은 생략한다. 여기서, 단자수용브라켓(50)내에는 고정단자(31)의 머리부(33)를 단자홈(3)을 통해 노출시키는 탄성스프링(55)이 수용되어 있음은 물론이다.The casing 1 of the image forming apparatus, the fixed terminal 31 coupled to the terminal groove 3 of the casing 1, and the terminal receiving bracket 50 coupled to the rear of the fixed terminal 31 are the same as conventional. The description thereof will be omitted. Here, it is a matter of course that the elastic spring 55 for exposing the head 33 of the fixed terminal 31 through the terminal groove 3 is accommodated in the terminal accommodation bracket 50.

한편, 현상기(10)의 접속단자(61)는, 도 4에서 보다 구체적으로 볼 수 있는 바와 같이, 고정단자(31)와 상호 접촉하는 접촉면(62)에 결합홈(63)이 형성되어 있다. 이 결합홈(63)은 접촉면(62)에 대하여 반구형상으로 함몰형성되어, 고정단자(31)의 단부를 수용가능하다. 여기서, 고정단자(31)의 단부를 반구형상으로 돌출형성한다면, 반구형상의 함몰된 결합홈(63)내에 수용되어 안정적인 접촉상태를 유지할 수 있어서 바람직하다. 이러한 구성은 또한, 결합홈(63)의 바닥면과 고정단자(31)의 단부 사이의 접촉면적을 최대한 넓힐 수 있어서, 접촉불량의 문제를 효과적으로 개선가능하다.On the other hand, the connecting terminal 61 of the developing device 10, as can be seen in more detail in Fig. 4, the coupling groove 63 is formed in the contact surface 62 in contact with the fixed terminal 31. The coupling groove 63 is recessed in a hemispherical shape with respect to the contact surface 62 to accommodate the end of the fixed terminal 31. Here, if the end of the fixed terminal 31 is formed to protrude in a hemispherical shape, it is preferable to be accommodated in the hemispherical recessed coupling groove 63 can maintain a stable contact state. This configuration can also widen the contact area between the bottom surface of the coupling groove 63 and the end of the fixed terminal 31 as much as possible, thereby effectively improving the problem of contact failure.

여기서, 본 실시예에서는 비록 결합홈(63)이 반구형상으로 함몰형성되어 있지만, 예를 들어, 사각형이나 오각형등의 다각형상을 가지도록 구성할 수 있음은 물론이다. 이 때, 고정단자(31)의 단부 또한, 이러한 구조에 맞물림수용될 수 있도록 다각형상으로 가공하는 것이 바람직하며, 이에 의해, 상술한 동일 목적 및 동일 효과를 달성할 수 있음은 물론이다.Here, although the coupling groove 63 is recessed in a hemispherical shape in the present embodiment, for example, it can be configured to have a polygonal shape such as a quadrangle or a pentagon. At this time, the end of the fixed terminal 31 is also preferably processed into a polygonal shape so that it can be meshed with such a structure, thereby, of course, can achieve the same purpose and the same effect described above.

현상기(10)의 접속단자(61)에는 한편, 결합홈(63)의 바닥면에 그 반경방향으로 외향 함몰된 이물질수집홈(65)이 형성되어 있다. 이 이물질수집홈(65)내에는 접속단자(61)와 고정단자(31) 사이에 개재되는 예를 들어, 먼지나 토너입자들이 유입되며, 이에 의해, 이물질에 의한 통전불량 현상을 방지할 수 있다.On the other hand, the connection terminal 61 of the developing device 10 is formed with a foreign matter collecting groove 65 recessed outward in the radial direction on the bottom surface of the coupling groove 63. In this foreign matter collection groove 65, for example, dust or toner particles are interposed between the connection terminal 61 and the fixed terminal 31, thereby preventing poor electricity supply due to foreign matter. .

한편, 상술 및 도시한 실시예에서는, 이물질수집홈(65)을 단지 현상기(10)의 접속단자(61)에만 형성한 것에 대하여 설명하였지만, 현상기(10)의 케이싱본체내부와 연통하도록 구성할 수도 있다. 이러한 경우, 이물질수집홈(65)내로 유입되는 이물질을 케이싱본체의 내부로 인출유도할 수 있으며, 이에 의해, 이물질수집홈(65)내에 축적되는 이물질을 청소하기 위한 주기적이고 곤란한 작업을 제거할 수 있어서 바람직하다.On the other hand, in the above-described and illustrated embodiments, the foreign matter collecting groove 65 was formed only in the connection terminal 61 of the developing device 10, but may be configured to communicate with the inner casing body of the developing device 10. have. In this case, foreign matter introduced into the foreign matter collecting groove 65 may be led out of the casing body, thereby eliminating periodic and difficult work for cleaning the foreign matter accumulated in the foreign matter collecting groove 65. It is preferable.

이상 설명한 바와 같이, 본 발명에 따르면, 탄성스프링의 탄성력이 규정치를 벗어나거나 혹은 시간이 경과하면서 그 탄성력이 약해지거나 불균일해지는 경우에도 현상기의 접속단자와 케이싱의 고정단자가 양호한 접속상태를 유지할 수 있는 현상기의 전원인가용 단자구조가 제공된다. 본 현상기의 전원인가용 단자구조는, 케이싱의 고정단자와 현상기의 접속단자 사이의 접촉면적을 최대한 넓혀 접속불량이 발생할 우려를 대폭 줄일 수 있다.As described above, according to the present invention, even when the elastic force of the elastic spring is out of the specified value or the elastic force becomes weak or uneven with time, the connection terminal of the developing device and the fixed terminal of the casing can maintain a good connection state. A terminal structure for applying power to the developer is provided. The terminal structure for power supply of the present developer can greatly reduce the possibility of connection failure by widening the contact area between the fixed terminal of the casing and the connecting terminal of the developer as much as possible.

본 현상기의 전원인가용 단자구조는 또한, 케이싱의 고정단자와 현상기의 접속단자 사이에 이물질이 개재되는 방지하여 그 통전상태를 양호하게 유지할 수 있으므로 더욱 효과적이다.The power supply terminal structure of the present developer is also more effective because it prevents foreign matters from interposed between the fixed terminal of the casing and the connecting terminal of the developing device, thereby maintaining its energized state well.
