본 고안은 스텝모터의 고정자 코일과 외부 구동전원 공급선을 전기적으로 접속하기 위한 두 가지부재가 제공된 스텝모터용 고정자에 관한 것이다.The present invention relates to a stator for a step motor provided with two members for electrically connecting the stator coil of the step motor and an external driving power supply line.

종래의 스텝모터용 고정자에 있어서, 고정자에 형성된 코일의 단자선이 납땜 또는 다른 방법으로 외동구동 전원 공급선에 직접 접속되어 있는 기술은 일본 실용신안 공개공보번호 57-151957와 일본 실용신안 공개공보번호 57-146307에 기술되어 있고, 복수의 접속부재, 즉 단자들이 단자를 통해서 코일과 구동전원 공급선의 단자선을 접속하도록 고정자의 한부분에 배치된 지지부재, 즉 단자기부에 집합적으로 장착되어 있는 기술이 일본 실용신안 공개공보번호 59-18550에 기술되어 있다.In the stator for a conventional step motor, the technique in which the terminal line of the coil formed in the stator is directly connected to the external drive power supply line by soldering or other method is disclosed in Japanese Utility Model Publication No. 57-151957 and Japanese Utility Model Publication No. 57 A technique described in -146307, in which a plurality of connecting members, that is, terminals are collectively mounted on a supporting member, ie, a terminal base portion, disposed at one part of a stator to connect a terminal line of a coil and a driving power supply line through the terminal. This Japanese Utility Model Publication No. 59-18550 is described.

제 3 도는 상기의 공지기술을 나타내는 것으로 코일(21)의 단자선(21A,21B,21C)이 각 접속점(PA,PB,PC)에서 구동전원 공급선(22A,22B,22C)에 직접 납땜되며 그후 접속점위에 테이프를 감는다.3 shows the above-mentioned known technology, in which the terminal lines 21A, 21B and 21C of the coil 21 are directly soldered to the driving power supply lines 22A, 22B and 22C at each connection point PA, PB and PC. Wind the tape over the connection point.

제 4 도는 코일(도시안됨)의 단자선에 접속된 각 하단(도시안됨)과 구동전원 공급선(32A,32B,32C)에 접속된 각 상단을 가진 단자(31A,31B,31C)를 포함하며, 스텝모터(30)의 케이스에 고정된 종래의 단자 장착부재(31)를 나타낸다.4 includes terminals 31A, 31B and 31C having respective lower ends (not shown) connected to the terminal lines of the coil (not shown) and each upper end connected to the driving power supply lines 32A, 32B and 32C, The conventional terminal mounting member 31 fixed to the case of the step motor 30 is shown.

제 3 도에 도시된 상술한 종래기술에 있어서, 코일(21)의 단자선(21A,21B,21C)의 구동전원 공급선(22A,22B,22C)에 직접 접속되기 때문에 구동전원 공급선(22A,22B,22C)에 강한 외력이 가해질 경우, 코일(21)의 단자선(21A,21B,21C)을 파손시키게 된다는 결점을 지니고 있다.In the above-described prior art shown in FIG. 3, the drive power supply lines 22A, 22B are directly connected to the drive power supply lines 22A, 22B, 22C of the terminal lines 21A, 21B, 21C of the coil 21. When a strong external force is applied to 22 C, the terminal lines 21A, 21B and 21C of the coil 21 are damaged.

제 4 도에 도시된 종래기술에 있어서, 소형고정자는 소형 단자 장착부재, 즉 단자기부(31)가 필요하게 되어 단자 사이의 간격이 근접되어 있으므로 접속효율이 저하되고, 더구나 단자 사이의 근접한 간격으로 인해서 회로가 단락되려 한다.In the prior art shown in FIG. 4, the small stator requires a small terminal mounting member, i.e., the terminal base portion 31, so that the spacing between the terminals is close, so that the connection efficiency is lowered. This will cause a short circuit.

본 고안의 주요한 목적은 두 지지부재를 제공함으로서 종래기술과 관련한 상기 결점을 극복하기 위한 것이며, 이 지지부재는 고정자의 코일의 단자선과 구동전원 공급선 사이의 접속을 하기에 적합하며 서로로부터 떨어져, 예를들면, 그들 사이에 180도의 최대 원주간격을 지닌상태로 고정자의 외주에 배치되며, 이 지지부재의 각각은 구동 전원 공급선이 그들 공급전압 극성에 따라 분할된 그룹중의 하나에 접속되어 있다.The main object of the present invention is to overcome the drawbacks associated with the prior art by providing two support members, which are suitable for making a connection between the terminal line of the coil of the stator and the drive power supply line and are separated from each other, eg For example, they are disposed on the outer periphery of the stator with a maximum circumferential spacing of 180 degrees between them, each of which is connected to one of the groups in which the drive power supply lines are divided according to their supply voltage polarity.

본 고안의 다른 목적은 회로의 단락을 방지하고 선접속 조작을 용이하게 할 수 있는 스텝모터의 제공하기 위한 것이다.Another object of the present invention is to provide a step motor that can prevent a short circuit and facilitate wire connection operation.

본 고안의 또 다른 목적은 고정자 코일의 단자선이 외력으로 인해 파손되는 것을 방지할 수 있는 스텝모터의 고정자를 제공하려는 것이다.Another object of the present invention is to provide a stator of a step motor that can prevent the terminal wire of the stator coil from being damaged by external force.

본 고안에 따른 스텝모터용 고정자는 제1 및 제2지지 부재와, 일단이 고정자 코일의 복수의 단자선중의 하나에 접속되며 타단이 고정자 코일에 구동전원을 공급하기에 적합한 구동전원 공급선에 접속되고 제1 및 제2지지부재에 별도로 장착된 그룹에 동일한 구동 전원 공급전압 극성을 가진 전도성 접속부재로 이루어지며, 이 제1 및 제2지지부재는 그들 사이에 최대 간격을 가진채 고정자의 외주상에 배치되어 있는 것이 특징이다.The stator for the step motor according to the present invention has a first and a second support member, one end of which is connected to one of a plurality of terminal lines of the stator coil, and the other end of which is connected to a driving power supply line suitable for supplying driving power to the stator coil. A conductive connection member having the same drive power supply voltage polarity in a group separately mounted to the first and second support members, the first and second support members on the outer circumference of the stator with a maximum spacing therebetween. It is characterized by being arranged.

상기 구조에 있어서, 제1 및 제2지지부재 180도 정도로 상대적인 원주간격을 가지고 고정자의 외주상에 배치되어 있으며, 이들은 극성이 다른 구동전원 공급전압이 인가되는 각각에 선의 그룹에 접속되어 있다. 이는 구동전원 공급선이 장착된 접속부재 사이의 장착간격을 넓게하여 회로의 단락을 방지함과 동시에 선에 강한 외력이 작용할 때 접속부재에만 인장력이 전달되고 코일의 단자선에 인장력이 작용하지 않도록 하여 코일의 파손을 방지한다.In the above structure, the first and second supporting members are disposed on the outer circumference of the stator with relative circumferential intervals of about 180 degrees, and they are connected to groups of lines to each of which a driving power supply voltage having a different polarity is applied. This prevents the short circuit of the circuit by widening the mounting interval between the connecting members on which the driving power supply line is installed. To prevent breakage.

본 고안은 첨부된 도면과 관련하여 청구범위와 상세한 설명으로부터 보다 명백하게 될 것이다.The invention will become more apparent from the claims and the description taken in conjunction with the accompanying drawings.

제 1 도는 스텝모터용 고정자의 분해도로서, 코일(2)이 절취부(1A)를 지닌 보빈(1) 둘레에 감겨있고, 중간 단자선(2A), 초기단자선(2B) 및 종단자선(2C)이 코일(2)에서 인출되어 있다.1 is an exploded view of a stator for a step motor, in which a coil 2 is wound around a bobbin 1 having a cutout 1A, and an intermediate terminal line 2A, an initial terminal line 2B, and a terminal line 2C. ) Is drawn out from the coil 2.

다음에 기술된 지지부재(6,7)가 보빈(1)의 각 절취부(1A)에 장착되어 있다. 그 내부원주에 형성된 복수의 극치(polar teeth)(3A)와 절취부(3B)를 지닌 컵형상 고정자부재(3)가 코일(2)에 결합되며, 같은 방법으로 극치(3A)는 보빈(1)의 절취부(1A)와 함께 일치된 절취부(3B)를 가진 보빈(1)의 중공부(1B)에 삽입된다.The supporting members 6 and 7 described next are attached to each cutout portion 1A of the bobbin 1. A cup-shaped stator member 3 having a plurality of polar teeth 3A and cutouts 3B formed in the inner circumference thereof is coupled to the coil 2, and in the same manner, the extreme teeth 3A are bobbins 1. Is inserted into the hollow portion 1B of the bobbin 1 with the cutout portion 3B coincided with the cutout portion 1A.

상기한 바와같이 컵형상 고정자부재(3). 보빈(1) 및 지지부재(6,7)를 결합한 후에 그 내경부에 형성된 복수의 극치(4A)와 절취부(4B)를 가진 플레이트(4)가 컵형상 고정자부재(3)에 대하여 그 대향면상 보빈(1)에 장착되며, 같은 방법으로 극치(3A)와 극치(4A)는 보빈(1)의 절취부(1A)와 함께 일치된 절취부(4B)와 서로 교대로 놓이게 된다.The cup-shaped stator member 3 as described above. After joining the bobbin 1 and the supporting members 6 and 7, a plate 4 having a plurality of extremes 4A and cutouts 4B formed in the inner diameter portion thereof is opposed to the cup-shaped stator member 3. Mounted on the planar bobbin 1, the extremes 3A and 4A are alternately placed with the cutouts 4B coincident with the cutouts 1A of the bobbin 1 in the same manner.

이상과 같이 보빈(1), 컵형상 고정자부재(3), 플레이트(4) 및 지지부재(6,7)가 조립되고 접착제등에 의해서 서로 일체로 고착된다.As mentioned above, the bobbin 1, the cup-shaped stator member 3, the plate 4, and the support members 6 and 7 are assembled and fixed together integrally by an adhesive or the like.

지지부재(6)에는 단자(6A,6B)가 부착되어 있고, 이 단자(6A,6B)는 지지부재(6) 내에 상호 접속되어 있기 때문에 통전상태에 있다.Terminals 6A, 6B are attached to the support member 6, and these terminals 6A, 6B are in an energized state because they are connected to each other in the support member 6.

단자(6A)에는 코일(2)의 중간단자선(2A)이 접속되고 다른단자(6B)에는 양전극의 코일(2)의 중간단자선(2A)이 접속되고 다른단자(6B)에는 양전극의 공급전압이 인가되는 구동전원 공급선(8)이 접속된다.The intermediate terminal line 2A of the coil 2 is connected to the terminal 6A, the intermediate terminal line 2A of the coil 2 of the positive electrode is connected to the other terminal 6B, and the positive electrode is supplied to the other terminal 6B. The driving power supply line 8 to which a voltage is applied is connected.

한편 지지부재(7)에는 단자(7A,7B)와 다른단자(7C,7D)가 부착되어 있다. 단자(7A,7B)와 단자(7C,7D)가 지지부재(7)내에 상호 접속되어 있기 때문에 각각 통전상태에 있다.On the other hand, the supporting member 7 is attached with terminals 7A, 7B and other terminals 7C, 7D. Since the terminals 7A, 7B and the terminals 7C, 7D are interconnected in the support member 7, they are in energized state, respectively.

단자(7A)에는 코일(2)의 초기단자선(2B)이 접속되고 단자(7C)에는 코일(2)의 종단자선(2C)이 접속되어 있다.The initial terminal line 2B of the coil 2 is connected to the terminal 7A, and the terminal terminal line 2C of the coil 2 is connected to the terminal 7C.

한편 단자(7B)에는 구동전원 공급선(9)이 접속되고 단자(7D)에는 다른 구동전원 공급선(10)이 접속되어 있다.On the other hand, the drive power supply line 9 is connected to the terminal 7B, and the other drive power supply line 10 is connected to the terminal 7D.

상기 접속상태에 있어서 지지부재(6) 측에 접속된 구동전원 공급선(8)의 인가 전압극성은 플러스이고, 지지부재(7)측에 접속된 구동전원 공급선(9,10)의 인가전원 극성은 마이너스이기 때문에, 예를들어 지지부재(7)의 단자(7A,7C) 또는 (7B,7D)사이에서 단락이 발생하여도 동전위 단락으로 인해 스파크를 발생시키고 않고 단자와 선을 손상시키지 않는다. 또 지지부재(6,7)는 180도의 원주간격으로 배치되기 때문에 구동전원 공급선(8)이 장시간 진동이나 외벽에 의해 단자(6B)로부터 벗겨져도 구동전원 공급선(9) 또는 (10)과 단락하는 것이 거의 없게 된다.In the connected state, the applied voltage polarity of the drive power supply line 8 connected to the support member 6 side is positive, and the applied power polarity of the drive power supply lines 9 and 10 connected to the support member 7 side is positive. Since it is negative, for example, a short circuit between the terminals 7A, 7C or 7B, 7D of the supporting member 7 does not cause sparks due to the coincidence short circuit and does not damage the terminals and the wires. In addition, since the support members 6 and 7 are arranged at circumferential intervals of 180 degrees, the driving power supply line 8 is short-circuited with the driving power supply line 9 or 10 even if the driving power supply line 8 is peeled off from the terminal 6B by vibration or an outer wall for a long time. There is almost nothing.

구동전원 공급선(9) 또는 (10)이 단자(7B) 또는 (7C)로부터 벗겨지는 경우에도 동일한 결과를 가져온다.The same result is obtained when the driving power supply line 9 or 10 is peeled off from the terminal 7B or 7C.

제 2a 도 내지 2c 도는 제 1 도에 도시된 형식의 스텝모터의 고정자를 2개 결합시킨 본 고안의 다른 실시예를 나타내는 것으로서, 스텝모터의 제1고정자(S1)와 제2고정자(S2)가 서로 결합되어 있다.2A to 2C show another embodiment of the present invention in which two stators of the step motor of the type shown in FIG. 1 are coupled, and the first stator S1 and the second stator S2 of the step motor Are combined with each other.

제 2a 도 내지 2c 도에서, 제 1 도의 부재명칭 및 번호와 대응하는 부재는 동일한 번호를 사용하고, 도면에 기재한 부호(S1) 및 (S2)는 제1 및 제2의 고정자(S1) 및 (S2)에 속하는 부재로 표시하기로 한다.In Figs. 2A to 2C, members corresponding to the member names and numbers in Fig. 1 use the same numbers, and reference numerals S1 and S2 shown in the drawings denote first and second stators S1 and It is indicated by the member belonging to (S2).

제 2a 도 내지 2c 도에서 명백한 바와같이, 제1고정자(S1)의 지지부재(6,7)는 각각 180도의 원주각 간격으로 부착되어 있으므로 구동전원 공급선이 장기간 진동하거나 외력에 의해 단자로부터 벗겨진 경우에도 단락이 일어날 염려가 없게 된다.As is apparent from FIGS. 2A to 2C, the support members 6 and 7 of the first stator S1 are attached at circumferential intervals of 180 degrees, respectively, even when the driving power supply line vibrates for a long time or is peeled off from the terminal by external force. There is no risk of a short circuit.

또 단자를 2개의 지지부재에 분할배치하고 있기 때문에 단자간격을 넓게할 수 있고, 접속작업이 용이하다.In addition, since the terminals are dividedly arranged in two supporting members, the terminal interval can be widened, and the connection work is easy.

더구나 구동전원 공급선에 강한 외력이 가해질 경우에도 이 외력이 직접 코일(2)의 단자선에 영향을 미치지 않는다.Moreover, even when a strong external force is applied to the drive power supply line, the external force does not directly affect the terminal line of the coil 2.

이상과 같이 본 고안의 적절한 실시예를 기술하였으나 본 고안의 정신을 벗어나지 않고 여러 가지 변경과 수정을 할 수 있음을 이해할 수 있을 것이다.Although the preferred embodiments of the present invention have been described as described above, it will be understood that various changes and modifications can be made without departing from the spirit of the present invention.
