본 고안은 스핀들 모터에 있어서, 로터의 회전을 감지하는데 사용되는 자기소자에 대한 것으로 특히 PCB와의 결합 구조를 개선한 것이다.The present invention is directed to a magnetic element used to sense the rotation of a rotor in a spindle motor, in particular to improve the coupling structure with the PCB.

일반적으로 자기소자는 로터의 외주면에 근접된 위에서 PCB에 입설되어 있으며, 상기한 로터의 외주면에 마련된 초다극마그네트로부터 그 회전상태를 감지하도록 되어 있다.In general, the magnetic element is placed in the PCB from the top adjacent to the outer circumferential surface of the rotor, it is to detect the rotation state from the ultra-multipolar magnet provided on the outer circumferential surface of the rotor.

그리고 이러한 종래의 자기소자는 제1도 도면에서 보듯이 글래스 소자(a)의 감지면(b)이 로터를 향하도록 하되, 단자(c)를 가진 본체(d)는 나사등을 이용해 PCB(e)에 입설고정하도록 되어 있다.In the conventional magnetic element, as shown in FIG. 1, the sensing surface b of the glass element a faces the rotor, but the main body d having the terminal c is formed using a PCB or the like. It is supposed to be locked in.

그러나 이러한 종래의 자기소자는 글래스 소자(a)가 본체(d)에 먼저 결합되어야 하고, 그 본체(d)의 안쪽으로 연장된 리드 단자(c)를 통해서만 PCB(e)에 연결되며, 또 본체(d)는 나사등의 체결부재를 사용하여야 하기 때문에 생산성 저조하고, 원가 상승의 요인이 되었다.However, such a conventional magnetic element has a glass element (a) must first be coupled to the main body (d), and is connected to the PCB (e) only through a lead terminal (c) extending inwardly of the main body (d). As (d) requires the use of fastening members such as screws, the productivity is lowered and the cost increases.

따라서 본 고안은 상기와 같은 종래의 여러 가지 문제점을 해결하기 위해 안출한 것으로 고안의 주된 목적은 자기소자를 PCB에 결합하되, 글래스 소자의 접점이 직접 PCB에 연결되도록 하고, 이를 감싸는 본체 역시 금속체로 하여 PCB에 납땜으로 부착될 수 있도록 하므로서 생산성 향상 및 원가 절감에 기여할 수 있도록 하는데 있다.Therefore, the present invention was devised to solve the various problems as described above. The main purpose of the present invention is to couple the magnetic elements to the PCB, but the contacts of the glass elements are directly connected to the PCB, and the main body surrounding them is also made of metal. By attaching to the PCB by soldering, it is possible to contribute to productivity and cost reduction.

그리고 이를 위한 주요 구성은 감지면을 가지는 글래스 소자와, 상기한 글래스 소자를 감합하되, 양측으로 지지편이 연장되는 본체를 마련한 후, 상기한 글래스 소자를 본체에 끼우되, 글래스 소자의 감지면에 마련된 접촉부가 직접PCB의 패턴에 접촉 연결되도록 하고, 본체의 배면 및 측면의지지 몇으로 PCB에 납땜하여 지지 고정하도록 하는데 있는 것이다.And the main configuration for this is a glass element having a sensing surface and the above-mentioned glass element is fitted, the main body extending the support piece on both sides, and then put the glass element on the main body, provided on the sensing surface of the glass element The contact portion is to be directly connected to the pattern of the PCB, and to support and fix the solder by soldering to the PCB with the support of the back and side of the body.

이하 첨부 도면에 따라 본 고안의 구성 및 작용 효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention in detail according to the accompanying drawings.

제2도는 본 고안의 구성을 보인 사시도로서 본체(1)와 그 속에 끼워진 글래스 소자(2)를 볼 수 있다.2 is a perspective view showing the structure of the present invention, whereby the main body 1 and the glass element 2 fitted therein can be seen.

여기서 상기한 글래스 소자(2) 그 감지면(21)의 아래에 접촉부(22)가 직접 PCB(3)에 접하게 되어 있으며, 또한 본체(1)는 지지편(11)이 있고, 이를 납땝등의 수단으로 직접 PCB(3)에 고정되는 것이며, 이는 단면도인 제2도를 통해 자세히 볼 수 있다.Here, the contact portion 22 directly under the sensing surface 21 of the glass element 2 is directly in contact with the PCB 3, and the main body 1 has a support piece 11, It is fixed to the PCB 3 directly by means, which can be seen in detail in FIG.

다음은 상기와 같이 구성된 본 고안 작동 상태에 대해서 설명한다.The following describes the present invention operating state configured as described above.

상기한 글래스 소자(2) 감지면(21)이 로터(도시하지 않았음)를 향하고 있어 그 로토의 초다극마그네트에서 발생하는 자장으로 회전상태를 감지함은 종래와 대동소이 하다.The glass element 2 sensing surface 21 is directed toward the rotor (not shown), and the rotational state is detected by a magnetic field generated by the ultra-multipolar magnet of the roto.

이상에서 자세히 설명한 바와 같이 본 고안은 글래스 소자(2)의 감지면(21)을 접촉부(22)로서 직접 PCB(3)에 연결하도록 되어 있기 때문에 접촉상태가 향상되고, 또 본체(1)역시 납땜등의 방법으로 PCB(3)입설 되도록 하였기 때문에 나사등이 불필요하여 원가 절감과 동시에 생산성이 향상되는 장점이 있다.As described in detail above, the present invention is designed to connect the sensing surface 21 of the glass element 2 directly to the PCB 3 as the contact portion 22, so that the contact state is improved, and the main body 1 is also soldered. Since the PCB (3) is installed in such a way, there is an advantage that the productivity is improved at the same time as the cost is unnecessary because screws are not required.
