본 고안은 케이스 형태의 세라믹 부저에 관한 것으로 특히 전원과 연결시켜 주는 리드선의 납땜 부위 단선을 방지하기에 적당한 구성으로 이루어진 압전 세라믹 부저의 케이스에 관한 것이다.The present invention relates to a ceramic buzzer in the form of a case, and more particularly, to a case of a piezoelectric ceramic buzzer having a configuration suitable for preventing a disconnection of a soldering part of a lead wire connected to a power source.
종래의 압전 세라믹 부저는 제1도와 같이 진동판(3)에 전극이 형성된 압전 세라믹 소자(2)를 접착시켜 진동판(3)과 압전 세라믹 소자(2) 전극에 리드선(6)을 납땜(7)하여 고정시키고 음압을 높이기 위하여 케이스(4)에 리드선(6)이 부착된 압전 세라믹 엘리먼트(1)를 실리콘 접착한 다음, 케이스(4)의 측면에 있는 1개의 홈(8)으로 리드선(6)을 곧게 뽑아낸 다음 제2도와 같이 뚜껑(5)을 덮는 형태로 구성되어 있어, 전원과 압전 세라믹 엘리먼트(1)를 연결시켜 주는 리드선(6)과 진동판(3) 및 압전 세라믹 소자(2) 전극의 납땜(7) 연결부위 인장력이 약하여 취급이 외부함(리드선의 당김)에 의하여 압전 세라믹 소자(2) 전극의 납땜(7) 연결 부위가 쉽게 떨어져 압전 세라믹 부저의 기능, (압전 세라믹 엘리먼트의 진동에 의한 음발생)을 상실하거나 리드선(6)과 압전 세라믹 엘리먼트 접촉이 제대로 되지 않아 이상음이 발생되었던 것이다.The conventional piezoelectric ceramic buzzer adheres the piezoelectric ceramic element 2 having the electrode to the diaphragm 3 as shown in FIG. 1, and solders the lead wire 6 to the diaphragm 3 and the piezoelectric ceramic element 2 electrodes. In order to fix and increase the sound pressure, the piezoelectric ceramic element 1 having the lead wire 6 attached to the case 4 is silicon-bonded, and then the lead wire 6 is connected to one groove 8 on the side of the case 4. The lead wire 6, the diaphragm 3, and the piezoelectric ceramic element 2, which are connected to the power supply and the piezoelectric ceramic element 1, are formed to cover the lid 5 as shown in FIG. 2. Soldering (7) connection part is weak due to external tension (pull of lead wire), and the soldering (7) connection part of the electrode of the piezoelectric ceramic element (2) is easily separated, so the function of the piezoelectric ceramic buzzer is reduced. Sound generation), or the lead wire 6 and the piezoelectric ceramic An abnormal sound occurred because of poor contact with the elements.
그러나 상기와 같은 종래의 부저 케이스 구성은 납땜 연결 부분에서 인장력이 약하여 납땜한 부위가 쉽게 떨어지고 납땜 부착 부위의 리드선이 쉽게 끊어지며 케이스와 압전 세라믹 엘리먼트의 실리콘 접착이 떨어져 부저의 기능이 상실되거나 진동이 고르지 못하여 이상음이 발생하는 문제점이 있었던 것이다.However, the conventional buzzer case configuration has a weak tensile force at the soldering connection portion, so that the soldered portion is easily dropped, the lead wire at the soldering attachment portion is easily broken, and the silicone adhesion between the case and the piezoelectric ceramic element is lost, thereby losing the function of the buzzer or vibration. There was a problem that the abnormal sound occurs because of uneven.
이러한 여러 가지의 문제점들을 해결하기 위해 안출한 본 고안은 리드선의 고정을 더욱 확실하게 하기 위한 구성으로 지지대를 연장 돌출시키되 그것의 돌출 방향과 돌출 위치에 특징을 두고 형성하는 것으로 이를 첨부한 도면으로 상세하게 설명하면 다음과 같다.The present invention devised to solve these various problems is to extend the support in a configuration to more secure the fixing of the lead wire, characterized in that formed in the protruding direction and the protruding position thereof, as detailed in the accompanying drawings If you explain it as follows.
제3도는 본 고안에 대한 압전 부저 케이스의 사시도이고 제4도는 본 고안에 대한 압전 부저의 평면도에 관한 것으로 압전 세라믹 소자(2)를 진동판(3)에 접착시켜서 구성되는 압전 세라믹 엘리먼트(1)의 압전 세라믹 소자(2)와 진동판(3)에 리이드선(6)을 납땜하여 고정시키고, 음압을 높이기 위하여 케이스(4)에 리이드선이 부착된 압전 세라믹 엘리먼트(1)를 실리콘을 접착한다.3 is a perspective view of a piezoelectric buzzer case according to the present invention, and FIG. 4 is a plan view of the piezoelectric buzzer according to the present invention, and FIG. 4 is a view of a piezoelectric ceramic element 1 formed by adhering the piezoelectric ceramic element 2 to the diaphragm 3. The lead wire 6 is soldered and fixed to the piezoelectric ceramic element 2 and the diaphragm 3, and silicon is bonded to the piezoelectric ceramic element 1 having the lead wire attached to the case 4 in order to increase the sound pressure.
상기의 케이스(4)를 고정하기 위하여 돌출시킨 고정 리브(4a)의 측면에서 리드선 고정용 지지대(10)가 연장되게 튀어나오게 형성한다.The lead wire fixing support 10 protrudes from the side of the fixing rib 4a protruding to fix the case 4 so as to protrude.
상기의 구성을 좀더 상세하게 설명하면, 지지대(10)의 돌출 위치는 케이스의 외주연에서 리드선(6)을 감지에 충분한 간격을 띄워서 돌출 연장시키며 돌출 연장되는 지지대(10)는 원호적으로 형성하여 케이스(4)의 외주연과 지지대(10)의 내주연 사이에 일정 간격(9)을 형성한다.When the above configuration is described in more detail, the protruding position of the support 10 protrudes from the outer periphery of the case with sufficient distance to detect the lead wire 6, and the protruding support 10 is formed to be arcuate. A predetermined interval 9 is formed between the outer periphery of the case 4 and the inner periphery of the support 10.
그리고 감기는 리드선(6)이 빠져나가게 되는 것을 방지하기 위하여 지지대(10)의 선단 내주연부위에 이탈방지턱(10a)을 돌출시켜서 상기의 일정 간격(1)이 좁아지게 형성한다.In order to prevent the lead wire 6 from being pulled out, the predetermined distance 1 is formed to be narrowed by protruding the release preventing jaw 10a on the inner peripheral portion of the distal end of the support 10.
이러한 구성으로 이루어진 본 고안은 압전 세라믹 엘리먼트(1)를 케이스(4)내에 실리콘 접착한 다음, 압전 세라믹 소자(2)와 진동판(3)에 납땜을 한 다음 납땜이 된 리드선(6)을 지지대(10)에 감아 고정시킨 뒤 회로 구성을 위해 예정된 부품에 리드선(6)를 연결 고정시킨다.According to the present invention having the above configuration, the piezoelectric ceramic element 1 is silicon bonded to the case 4, and then the piezoelectric ceramic element 2 and the diaphragm 3 are soldered, and then the soldered lead wire 6 is supported. 10) and fix the lead wire (6) to the intended part for the circuit configuration.
이와 같이 압전 세라믹 부저의 케이스 구조에 의하여 취급시 리드선(6)에 외부의 힘이 가해져도 그 힘이 리드선(6)을 통하여 진동판(3)과 압전 세라믹 소자(2) 전극의 납땜 부위에 직접적으로 전달받지 않고 지지대(10)에서 외부힘을 전달받으므로서 납땜 부착 부위의 떨어짐과 단선을 방지하고, 특히 외부의 힘이 가해지는 것을 방지하게 되므로 케이스(4)와 압전 세라믹 엘리먼트의 실리콘 접착이 떨어지는 것을 방지할 수 있다.Thus, even when an external force is applied to the lead wire 6 during handling by the case structure of the piezoelectric ceramic buzzer, the force is directly applied to the soldering portion of the diaphragm 3 and the piezoelectric ceramic element 2 electrode via the lead wire 6. Since the external force is transmitted from the support 10 without being transmitted, it prevents the solder attachment portion from falling off and disconnection, and in particular, prevents the external force from being applied, so that the silicon adhesion between the case 4 and the piezoelectric ceramic element is inferior. Can be prevented.
따라서 압전 부저가 단락으로 인해 동작이 안되는 것을 방지할 수 있어 기능이 보호되어 사용 효과를 높일 수 있으며 그 구조가 간단하여 제작하기에 용이할 뿐만 아니라, 기존 제품에 즉시 이용 가능한 이점이 있는 것이다.Therefore, the piezoelectric buzzer can be prevented from operating due to a short circuit, so that the function is protected and the use effect can be enhanced, and its structure is simple and easy to manufacture, and there is an advantage that can be immediately used in existing products.
