진동모터의 장착구조{MOUNTING STRUCTURE OF VIBRATION MOTOR}MOTORTING STRUCTURE OF VIBRATION MOTOR

본 발명은 진동모터의 장착구조에 관한 것으로서, 보다 상세하게는 진동모터를 감싸서 지지하는 고무재의 지지부재의 형상을 개선한 진동모터의 장착구조에 관한 것이다.The present invention relates to a mounting structure of a vibration motor, and more particularly to a mounting structure of a vibration motor that improves the shape of the support member of the rubber material surrounding the vibration motor support.

오늘날 가장 대표적으로 사용되는 개인통신수단은 이동통신 단말기이고, 상기 이동통신 단말기에는 착신신호인 음(벨소리)과 진동을 발생하는 수단이 마련된다.The most representative personal communication means used today is a mobile communication terminal, and the mobile communication terminal is provided with means for generating an incoming signal (ring tone) and vibration.

상기 이동통신 단말기의 착신신호인 진동은 진동모터 의해서 발생하며 종래의 진동모터의 장착구조는 도 1을 참조하여 설명한다.Vibration that is an incoming signal of the mobile communication terminal is generated by a vibration motor, and a mounting structure of a conventional vibration motor will be described with reference to FIG. 1.

도 1은 종래의 진동모터가 이동통신 단말기에 설치된 상태를 보인 도이다.1 is a view showing a state in which a conventional vibration motor is installed in a mobile communication terminal.

도시된 바와 같이, 하우징(10)의 적소에는 PCB(11)가 마련되고, PCB(11) 상측에는 하우징커버(13)가 설치되는데, 하우징커버(13)의 내부에는 진동모터(20)가 설치된다. 진동모터(20)는 내부에 다수의 전기부품(미도시)이 내장된 케이스(21)와, 케이스(21)의 외주면을 둘러 감싼 고무재의 지지부재(23)를 가진다.As shown, the PCB 11 is provided in place of the housing 10, the housing cover 13 is installed above the PCB 11, the vibration motor 20 is installed inside the housing cover 13 do. The vibration motor 20 has a case 21 in which a plurality of electrical parts (not shown) are built, and a support member 23 of rubber material wrapped around the outer circumferential surface of the case 21.

그리고, 케이스(21)의 일측에는 탄성을 구비하는 접속단자(25)가 마련된다. 접속단자(25)의 일단부는 케이스(21)에 내장된 상기 전기부품와 접속하고, 타단부는 케이스(21)의 하부로 노출되어 PCB(11)와 접속된다.One side of the case 21 is provided with a connecting terminal 25 having elasticity. One end of the connection terminal 25 is connected to the electrical component built into the case 21, and the other end is exposed to the lower part of the case 21 and connected to the PCB 11.

그러나, 상기와 같은 종래의 진동모터의 장착구조는 접속단자(25)의 탄성력에 의해서만 접속단자(25)가 PCB(11)에 접속된다. 그러므로 진동모터(20)의 자체하중 또는 외부충격에 의해서 접속단자(25)가 쉽게 변형되고, 이로 인해 접속단자(25)와 PCB(11)간에 접속불량이 발생하는 단점이 있다.However, in the mounting structure of the conventional vibration motor as described above, the connection terminal 25 is connected to the PCB 11 only by the elastic force of the connection terminal 25. Therefore, the connection terminal 25 is easily deformed by the self-load or the external shock of the vibration motor 20, which causes a disadvantage in that connection failure occurs between the connection terminal 25 and the PCB 11.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창작된 것으로, 본 발명의 목적은 진동모터의 접속단자가 자체의 탄성력뿐만 아니라 지지부재에 의하여 지지되어 PCB에 접속되게 함으로써, 접속단자와 PCB사이의 접속불량을 해소할 수 있는 진동모터의 장착구조를 제공함에 있다.The present invention was created to solve the above problems, and an object of the present invention is to connect the connection between the connection terminal and the PCB by allowing the connection terminal of the vibration motor is supported by the support member as well as its elastic force. It is to provide a mounting structure of the vibration motor that can eliminate the defect.

도 1은 종래의 진동모터가 이동통신 단말기에 설치된 것을 보인 도.1 is a view showing that a conventional vibration motor is installed in a mobile communication terminal.

도 2는 본 발명의 일 실시예에 따른 진동모터의 사시도.2 is a perspective view of a vibration motor according to an embodiment of the present invention.

도 3은 본 발명의 일 실시예에 따른 진동모터가 이동통신 단말기에 설치된 것을 보인 도.Figure 3 shows that the vibration motor according to an embodiment of the present invention is installed in a mobile communication terminal.

이하, 첨부한 도면을 참고하여 본 발명의 일 실시예에 따른 진동모터의 장착구조를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the mounting structure of the vibration motor according to an embodiment of the present invention.

도 2는 본 발명의 일 실시예에 따른 진동모터의 사시도이고, 도 3은 본 발명의 일 실시예에 따른 진동모터가 이동통신 단말기에 설치된 것을 보인 도이다.2 is a perspective view of a vibration motor according to an embodiment of the present invention, Figure 3 is a view showing that the vibration motor according to an embodiment of the present invention is installed in a mobile communication terminal.

도시된 바와 같이, PCB(220)가 설치된 하우징(200)이 마련된다. PCB(220)상측의 하우징(200)부위에는 진동모터(100)가 설치되고, 진동모터(100)와 PCB(220)는 하우징커버(210)에 덮혀서 보호된다.As shown, a housing 200 in which the PCB 220 is installed is provided. The vibration motor 100 is installed on the housing 200 on the PCB 220, and the vibration motor 100 and the PCB 220 are covered and protected by the housing cover 210.

진동모터(100)는 케이스(110)를 구비한다. 케이스(110)에는 샤프트(120)가 관통 설치되고, 샤프트(120)의 반경방향 외측으로는 회전자(미도시) 및 고정자(미도시) 등과 같은 다수의 전기부품이 설치된다. 그리고, 케이스(110)의 외측으로 노출된 샤프트(120)의 단부에는 편심추(125)가 설치된다. 그리하여 샤프트(120)가 회전되면 편심추(125)에 의하여 진동이 발생된다.The vibration motor 100 has a case 110. The case 110 has a shaft 120 installed therethrough, and a plurality of electrical parts such as a rotor (not shown) and a stator (not shown) are installed at the radially outer side of the shaft 120. In addition, an eccentric weight 125 is installed at an end portion of the shaft 120 exposed to the outside of the case 110. Thus, when the shaft 120 rotates, vibration is generated by the eccentric weight 125.

그리고 케이스(110)에 내장된 상기 전기부품에는 접속단자(130)가 접속된다. 상세히 설명하면 접속단자(130)의 일단부는 상기 전기부품과 접속하고, 타단부는 벤딩되어 케이스(110)의 외부로 노출된다. 이때, 노출된 접속단자(130)의 타단부는 PCB(220)와 접속하여 전원을 진동모터(100)로 공급한다.In addition, a connection terminal 130 is connected to the electrical component embedded in the case 110. In detail, one end of the connection terminal 130 is connected to the electrical component, and the other end is bent and exposed to the outside of the case 110. In this case, the other end of the exposed connection terminal 130 is connected to the PCB 220 and supplies power to the vibration motor 100.

케이스(110)의 외주면에는 케이스(110)를 감싸는 형태로 지지부재(140)가 설치된다. 지지부재(140)의 저면에는 굴곡진 형태의 돌출부(141)가 마련되는데, 돌출부(141)는 제 1 돌출부(141a)와 제 2 돌출부(141b)를 가진다. 제 1 돌출부(141a)는 케이스(110) 저면에서 굴곡진 형태로 형성되어 PCB(220)에 접촉되고, 이로 인해진동모터(100)가 지지된다.The support member 140 is installed on the outer circumferential surface of the case 110 to surround the case 110. The bottom surface of the support member 140 is provided with a curved protrusion 141, the protrusion 141 has a first protrusion 141a and a second protrusion 141b. The first protrusion 141a is formed in a curved shape at the bottom of the case 110 to contact the PCB 220, thereby supporting the vibration motor 100.

제 1 돌출부(141a)에서 소정간격으로 이격된 제 2 돌출부(141b)도 굴곡진 형태로 마련되어 접속단자(130)의 타단부가 PCB(220)에 접속되게 접속단자(130)의 타단부를 탄성지지 한다. 그러므로, 접속단자(130)는 자체의 탄성력과 제 2 돌출부(141b)에 의하여 PCB(220)에 견고하게 접속된다.The second protrusion 141b spaced apart from the first protrusion 141a at a predetermined interval is also bent, so that the other end of the connection terminal 130 is elastic so that the other end of the connection terminal 130 is connected to the PCB 220. I support it. Therefore, the connection terminal 130 is firmly connected to the PCB 220 by its elastic force and the second protrusion 141b.

이상에서 설명하듯이, 본 발명에 따른 상기 진동모터의 장착구조는 접속단자가 자체의 탄성력뿐만 아니라 지지부재에 지지되어 PCB와 접속되므로, 안정되게 PCB에 접속된다. 그러므로, 이동통신 단말기의 신뢰성이 향상된다.As described above, the mounting structure of the vibration motor according to the present invention is connected to the PCB stably because the connection terminal is connected to the PCB supported by the support member as well as its elastic force. Therefore, the reliability of the mobile communication terminal is improved.

이상에서는, 본 발명의 일 실시예에 따라 본 발명을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 변경 및 변형한 것도 본 발명에 속함은 당연하다.In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention. Of course.
