본 고안은 돔 스위치에 관한 것으로, 좀 더 상세하게는 휴대폰 등의 각종 통 신기기 또는 각종 전자기기의 회로접점용 키패드와 함께 사용되는 돔 스위치에 장방형상으로 형성된 복수개의 다 접점돌부를 중앙 접점돌부를 중심으로 원형으로 배치형성하여 접점력과 스위칭 효율을 향상시킨 돔 스위치에 관한 것이다.The present invention relates to a dome switch, and more particularly, a plurality of multi-contact protrusions formed in a rectangular shape on a dome switch used together with keypads for circuit contact of various communication devices such as mobile phones or various electronic devices. The present invention relates to a dome switch having a circular arrangement around a part to improve contact force and switching efficiency.

일반적으로 휴대폰 또는 각종 전자기기에는 입력키로서 주로 돔 스위치를 사용하고 있다.In general, a dome switch is mainly used as an input key in a mobile phone or various electronic devices.

입력키의 구조 및 작용을 살펴보면, 먼저, 고정접점과 스위치 접점이 구비된인쇄회로기판의 상부면에 하단부가 고정접점에 항상 접촉되고 융기된 상단부가 스위치 접점 상부에 위치되는 도전성의 탄성 메탈돔이 설치되며, 상기 탄성 메탈돔의 외부 둘레에 커버필름이 설치되는 형태이고, 상기 외부에서 탄성 메탈돔의 볼록한 상단부를 가압하면 상단부가 오목하게 탄성 변형되면서 스위치 접점에 온(ON)상태가 되고, 작용력을 제거하면 탄성 메탈돔의 상단부가 다시 볼록하게 원상 복귀되어 오프(OFF)상태가 된다.Looking at the structure and operation of the input key, first, a conductive elastic metal dome in which the lower end is always in contact with the fixed contact and the raised upper part is located above the switch contact is provided on the upper surface of the printed circuit board having the fixed contact and the switch contact. The cover film is installed on the outer circumference of the elastic metal dome, and when the convex upper end of the elastic metal dome is pressed from the outside, the upper end becomes concave and elastically deformed, thereby turning on the switch contact. After removing, the upper end of the resilient metal dome is returned to the original convex shape and is turned off.

이와 같은 탄성 메탈돔은 그 형태가 대부분 반원형의 형상으로 형성되고, 그 중앙부에 접점부가 형성되어 있다.Such an elastic metal dome is formed in a semicircular shape in most forms, and a contact portion is formed in the center thereof.

그리고, 접점부는 그 접점되는 부위의 모양에 따라 둥근 형태, 볼록한 딤플 형태, 구멍이 뚫린 형태 등으로 매우 다양하게 형성되어 있다.The contact portion is formed in various ways in a round shape, a convex dimple shape, a perforated shape, etc. according to the shape of the contact portion.

그러나, 위와 같은 딤플 형태의 기존의 돔 스위치의 경우에는 계속적인 반복 사용에 의하여 돔 스위치의 접점부에 먼지 등의 이물질이 지속적으로 쌓이고 달라 붙으면서 접점력이 저하되는 문제점이 있었다.However, in the case of the conventional dome switch of the dimple type as described above, there is a problem in that the contact force decreases as the foreign matter such as dust continuously accumulates and adheres to the contact portion of the dome switch by continuous repeated use.

본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 돔 스위치의 접점력을 향상시키고 스위칭 효율을 향상시킬 수 있는 장방형의 다 접점돌부를 형성시킨 돔 스위치를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the above problems, an object of the present invention is to provide a dome switch formed with a rectangular multi-contact protrusions that can improve the contact force of the dome switch and improve the switching efficiency.

그리고, 본 고안은 스위치의 누름시 중앙 접점돌부가 접촉되지 않아도 장방형의 다 접점돌부가 회로기판에 빠르게 접촉될 수 있고, 장방형상의 일측부위가 먼저 접촉되도록 형성됨으로서 스위칭 효율이 향상되도록 고안된 돔 스위치를 제공하는 것을 그 목적으로 한다.In addition, the present invention is a dome switch designed to improve the switching efficiency by being formed so that the rectangular multi-contact protrusions can be quickly contacted to the circuit board even when the center contact protrusions are not in contact when the switch is pressed, and the one side portion of the rectangular contact is formed first. Its purpose is to provide.

또한, 본 고안은 중앙 접점돌부의 외측에 원형으로 배치된 장방형상의 다 접점돌부를 형성하여 복수개의 접점 중 어느 하나가 접촉하여 동작하여도 스위칭 기능을 할 수 있도록 함으로써 접점 능력을 향상시키고 접점의 수명과 제품의 수명을 연장시킬 수 있는 돔 스위치를 제공하는 것을 그 목적으로 한다.In addition, the present invention forms a rectangular multi-contact protrusions arranged in a circular shape on the outside of the center contact protrusion to enable a switching function even when any one of the plurality of contacts in contact to improve the contact capability and the life of the contact The aim is to provide a dome switch that can extend the life of the product.

본 고안은 각종 통신기기 및 전자기기의 키패드에 사용되는 반구 형상의 돔 스위치에 있어서,The present invention is a hemispherical dome switch used for keypads of various communication devices and electronic devices,

상기 반구 형상의 돔 스위치 몸체 중앙에 중앙 접점 돌부가 형성되고, 상기 중앙 접점돌부의 주변에 원형으로 배치되고 장방형상으로 형성된 복수개의 다 접점돌부가 형성되며, 상기 중앙 접점돌부의 미접촉시 다 접점돌부가 접촉되도록 형성된 것을 특징으로 한다.A central contact protrusion is formed at the center of the hemispherical dome switch body, and a plurality of multi-contact protrusions are formed in a circular shape and are formed in a rectangular shape around the center contact protrusion, and the contact points of the central contact protrusion are not in contact. Characterized in that the portion is formed in contact.

이하, 첨부된 도면을 참조하여 본 고안의 구성 및 동작을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the subject innovation.

도 1은 본 고안의 돔 스위치의 구조를 보여주는 사시도이고, 도 2는 도 1의 평면도이고, 도 3은 도 2의 A-A선을 절단했을 때의 단면도이며, 도 4는 본 고안의 돔 스위치의 동작을 보여주는 측단면도이다.1 is a perspective view showing the structure of the dome switch of the present invention, Figure 2 is a plan view of Figure 1, Figure 3 is a cross-sectional view when the AA line of Figure 2, Figure 4 is an operation of the dome switch of the present invention Is a cross-sectional side view.

그리고, 상기 돔 스위치의 몸체(10)의 중앙부에는 중앙 접점돌부(12)가 형성되어 있다.In addition, a center contact protrusion 12 is formed at the center of the body 10 of the dome switch.

상기 중앙 접점돌부(12)는 원형으로 형성되어 있고, 상기 중앙 접점돌부(12)가 하향으로 가압되면서 미도시된 인쇄회로기판의 접점과 접촉된다.The center contact protrusion 12 is formed in a circular shape, and the center contact protrusion 12 is pressed downward to contact the contacts of the printed circuit board.

상기 중앙 접점돌부(12)의 외측 주변에는 장방형으로 형성된 다 접점돌부(14)가 원형으로 배치되어 형성되어 있다.A rectangular multi-contact protrusion 14 is formed in a circular shape around the outer side of the central contact protrusion 12.

상기 다 접점돌부(14)는 상기 중앙 접점돌부(12)를 누르면 중앙 접점돌부(12)가 먼저 접점을 형성하고 그와 동시에 주위의 다 접점돌부(14)가 접촉을 한다.When the multi contact protrusion 14 presses the center contact protrusion 12, the center contact protrusion 12 first forms a contact, and at the same time, the surrounding multi contact protrusion 14 contacts.

상기와 같은 다 접점돌부(14)는 6개 또는 8개 등으로 다양하게 형성할 수 있다.The multi-contact protrusions 14 as described above may be formed in various ways such as six or eight.

상기 다 접점돌부(14)는 본 고안에서는 바람직한 형상으로 장방형상으로 형성하였으나 원형 및 타원형도 형성할 수 있다.The multi-contact protrusions 14 may be formed in a rectangular shape in a preferred shape in the present invention, but may also be formed in circular and elliptical shapes.

상기 다 접점돌부(14)는 돔 스위치를 눌렀을 때, 도 4에 도시된 것과 같이 아래 방향으로 탄압되면서 눌려지고, 상기 다 접점돌부(14)가 미도시된 회로기판에 접촉되어 진다.When the dome switch 14 is pressed, the multi contact protrusion 14 is pressed while being pressed down as shown in FIG. 4, and the multi contact protrusion 14 is brought into contact with a circuit board not shown.

이때, 상기 다 접점돌부(14)의 네 곳 중 어느 한 곳이라도 회로기판에 접촉되는 경우 원활하게 스위칭 기능을 하게 된다.At this time, when any one of the four points of the multi-contact protrusions 14 is in contact with the circuit board is a smooth switching function.

상기와 같이 형성된 중앙 접점돌부(12)에 이물질이 쌓이더라도 상기 다 접점돌부(14)는 어느 한쪽으로 기울어지면서 적어도 한 곳 이상이 회로기판과 접촉되어 진다.Even if foreign matters accumulate on the central contact protrusions 12 formed as described above, the multi-contact protrusions 14 are inclined to one side and at least one place is in contact with the circuit board.

이상에서와 같이 기술된 본 고안은 상기에 기술된 바와 같은 바람직한 일실시예에 한정되지 아니하며, 본 고안의 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 본 고안이 속하는 기술분야에서 통상의 지식을 가진자라면 다양하게 변형실시가 가능한 것은 물론이고, 그와 같은 변경실시는 본 고안의 핵심요소로 기재된 청구범위 내에 존재한다고 할 것이다.The present invention described as described above is not limited to the preferred embodiment as described above, it is common in the art to which the present invention belongs without departing from the spirit of the present invention claimed in the claims of the present invention Those skilled in the art will be able to perform various modifications, as well as such modifications will be within the scope of the claims described as key elements of the present invention.

이와 같은, 본 고안의 돔 스위치는 복수개의 다 접점돌부가 중앙 접점돌부의 주변에 형성됨으로써 접점능력이 향상되고 스위칭 기능이 우수하게 향상되는 효과가 있고, 다 접점 돌부가 장방형으로 형성되어 접점 기능이 원할하게 이루어지며, 접점수명 및 제품의 수명이 오래가는 효과가 있다.As such, the dome switch of the present invention has a plurality of multi-contact protrusions formed around the center contact protrusion, so that the contact capability is improved and the switching function is excellently improved, and the multi-contact protrusion is formed in a rectangular shape so that the contact function is improved. It is made smoothly, and the life of the contact point and product life is long.
