일반적으로 압전소자를 이용한 가속도계 센서는 하우징 내측에서 압전소자를 하우징과 절연시키는 것은 하우징과 압전소자의 용량성 결합(capacitive coupling)으로 인하여 잡음에 취약한 결점이 있는 것으로 알려져 있다.In general, an accelerometer sensor using a piezoelectric element is known to insulate the piezoelectric element from the inside of the housing and to be vulnerable to noise due to capacitive coupling between the housing and the piezoelectric element.
상기와 같은 결점을 해소코자 센서에 있는 동축 케이블의 바깥도선이 하우징과 내부에서 연결된 가속도계 센서가 있다. 이 가속도계 센서는 절연나사를 이용하여 하우징을 외부의 마운팅 플레이트와 전기적으로 절연되게 결합하여 사용한다. 이때 나사의 절연은 나사에 절연슬리브 관을 삽입하고, 그 외측에 절연와셔를 삽입한 후, 상기 절연 슬리브 관의 외측에 가속도계 센서를 삽입하여 마운팅 플레이트에 고정시키는 방법으로 나사와 가속도계 센서의 전기적인 절연이 이루어지도록 한다.There is an accelerometer sensor in which the outer conductor of the coaxial cable in the sensor is connected in the housing and the inside to solve the above drawback. This accelerometer sensor uses an insulating screw to electrically connect the housing to the external mounting plate. At this time, the insulation of the screw is inserted into the insulating sleeve tube to the screw, the insulation washer is inserted into the outer side, and then the accelerometer sensor is inserted into the outer side of the insulating sleeve tube and fixed to the mounting plate by the electrical method of the screw and accelerometer sensor. Ensure insulation.
상술한 바와 같은 종래 절연나사를 이용하여 가속도계 센서가 취부된 상태가 도 1, 도 2에 도시되어 있는 바, 이를 간단히 설명한다.The state in which the accelerometer sensor is mounted using the conventional insulating screw as described above is illustrated in FIGS. 1 and 2, which will be described briefly.
도시된 바와 같이, 종래에는 나사 몸체(1a)의 후단부에 나사머리(1b)가 형성되어 있고 전단부에 수나사부(1c)가 형성되어 있는 나사(1)의 몸체(1a) 외측면에 절연슬리브관(2)이 밀착되도록 삽입하여 끼워져 있다.As shown, conventionally, the screw head 1b is formed at the rear end of the screw body 1a and the outer surface of the body 1a of the screw 1 having the male screw part 1c is formed at the front end. The sleeve tube 2 is inserted and fitted in close contact.
그리고, 그 절연슬리브관(2)의 외측에는 절연와셔(3)가 삽입되어 나사머리(1b)의 내측면에 밀착되어지고, 그와 같은 상태에서 가속도계 센서(4)의 하우징(5) 중앙부에 형성된 고정홀(5a)에 상기 나사(1)가 삽입되어진다.Then, an insulating washer 3 is inserted into the outer side of the insulating sleeve tube 2 to be in close contact with the inner surface of the screw head 1b. In such a state, the center of the housing 5 of the accelerometer sensor 4 is provided. The screw 1 is inserted into the formed fixing hole 5a.
또한, 상기와 같은 삽입된 나사(1) 수나사부(1c)가 형성된 부분에 절연와셔(6)가 삽입된 상태에서, 수나사부(1c)부분이 마운팅 플레이트(7)의 탭(7a)에 나사결합되어 있다.Further, in the state where the insulating washer 6 is inserted into the inserted screw 1 male threaded portion 1c formed portion, the male threaded portion 1c is screwed into the tab 7a of the mounting plate 7. Are combined.
상기와 같이 구성된 종래 절연나사를 이용하여 가속도계 센서(4)를 마운팅 플레이트(6)에 결합할때는 먼저 절연슬리브관(2)이 외측면에 삽입되어 있는 절연 나사(1)를 가속도계 센서(4)의 고정홀(5a)에 삽입하고, 그 가속도계 센서(4)의 반대쪽으로 돌출된 수나사부(1c)부위에 절연와셔(6)를 결합함과 아울러 마운팅 플레이트(7)의 탭(7a)에 나사결합한다. 그런후 그와 같이 결합된 마운팅 플레이트(7)를 진동시험하고자 하는 측정부위에 부착하여 진동을 측정하게 된다.When the accelerometer sensor 4 is coupled to the mounting plate 6 by using the conventional insulated screw configured as described above, first, the insulation screw 1 having the insulation sleeve 2 inserted into the outer surface of the accelerometer sensor 4 is removed. Inserted into the fixing hole 5a, the insulating washer 6 is coupled to the male screw portion 1c protruding to the opposite side of the accelerometer sensor 4, and screwed to the tab 7a of the mounting plate 7 do. Then, the mounting plate 7 coupled as described above is attached to the measurement site to be subjected to the vibration test to measure the vibration.
그러나, 상기와 같이 구성된 종래 절연나사를 이용한 가속도계 센서(4)의 취부구조에서는 나사(1)가 마운팅 플레이트(7)에 전기적으로 도통된 상태에서 수나사부(1c)부분과 가속도계 센서(4)의 하우징(5)간에 직접접촉 또는 이물질(습기 또는 먼지)에 의한 간접접촉에 의해 전기적인 도통이 이루어져서 정확한 진동시험이 이루어지지 못하는 문제점이 있었다.However, in the mounting structure of the accelerometer sensor 4 using the conventional insulated screw configured as described above, the portion of the male screw portion 1c and the accelerometer sensor 4 in a state where the screw 1 is electrically connected to the mounting plate 7. The electrical conduction is made by direct contact between the housing 5 or indirect contact by foreign matter (humidity or dust), there is a problem that the accurate vibration test is not made.
상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 나사가 원할하게 취부되도록 함과 아울러 가속도계 센서의 하우징이 결합되는 나사의 외측이 완전히 절연되어질 수 있도록 하는데 적합한 나사 절연장치 및 그 나사 절연장치에 의해 조립된 센서조립체를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention devised in view of the above problems is to provide a screw insulator and a screw insulator suitable for allowing the screw to be mounted smoothly and to allow the outside of the screw to which the housing of the accelerometer sensor is coupled to be completely insulated.
