본 고안은 모우터의 회전속도(R.P.M)조정용 저항기에 관한 것으로, 더욱 상세하게로는 저항기의 저항체구성을 세라믹 기판 표면상에 도체도료로써 실크 인쇄하여 박상(薄狀)으로 형성한 것에 의해, 저항기 몸체를 콤팩트하게 함과 아울러 저항체로부터의 발열은 약화시키어 주변 부품에 하등 영향을 주지 않도록 한 모우터의 회전속도 조정용 저항기(이하, 단순히 저항기라고 약칭함)에 관한 것이다.The present invention relates to a resistor for adjusting the rotational speed (RPM) of a motor. More specifically, the resistor structure of the resistor is formed by thin silk printing with a conductor paint on the surface of a ceramic substrate to form a resistor. The present invention relates to a resistor for adjusting the rotational speed of a motor (hereinafter simply abbreviated as a resistor) in which the body is made compact and heat generated from the resistor is weakened so as not to affect the peripheral parts at all.
종래, 자동차등에 사용되는 저항기는 본 출원인이 89.3.15.자로 출원하여 90.2.27.자 의장등록 제101,860호로 기등록 받고 있는 의장공보에 개시된 바와같이, 저항체를 코일상으로 하여 커넥터하우징에 입설된 단자상단에 연결시키고 있는 구조로 되어 있기 때문에, 저항기의 구조가 복잡하게 됨과 아울러 제작조립이 매우 힘들다고 하는 폐단이 있었다.Conventionally, resistors used in automobiles and the like have been placed in a connector housing with a resistor in the form of a coil, as disclosed in a design publication filed by the present applicant with the registration of Patent No. 101,860, filed as 89.3.15. Since the structure is connected to the upper end of the terminal, the structure of the resistor is complicated and the assembly is very difficult.
특히, 저항체가 코일상으로 구성되어 있으므로 인해 전류에 대한 저항 작용시 코일로부터 강한 열이 발생되어 주위에 근접 배치된 다른 부품들에게로 악영향을 끼치게 하는 폐단이 있고, 이러한 폐단을 방지코져 코일상면 일부위에 걸쳐서 방열 차단재를 도포하고 있으나, 방열차단재도포로 인한 저항기의 제조원가 상승요인만 유발시킬뿐, 일부만의 도포로 인해 그다지 큰 발열차단 효과는 발휘하지 못한다고 하는 결점을 내포하고 있는 것이었다.Particularly, since the resistor is formed in a coil shape, there is a closed end that generates strong heat from the coil when the resistance to current causes it to adversely affect other parts disposed close to the surrounding part. Although the heat dissipation blocking material is applied over the above, it only induces an increase in the manufacturing cost of the resistor due to the application of the heat dissipation blocking material, and implies a drawback that only a part of the coating does not exert a great heat blocking effect.
본 고안은 상기 제반 결점들을 해소키위하여 안출한 것으로, 저항기를 보다 콤팩트하게 간단한 공정으로 제조할 수 있도록한 잇점을 제공함과 아울러, 저항기의 저항체로 부터의 발열상태를 약화시킨 잇점을 제공함에 있고, 기타 저항기와 접속되는 모우터 소손방지용 단락부와 저항체의 발열을 외부로 쉽게 방열되게하는 방열판을 제공함에 있다.The present invention has been made to solve the above-mentioned shortcomings, and provides an advantage that the resistor can be manufactured in a more compact and simple process, and also provides an advantage of weakening the heating state from the resistor of the resistor, The present invention provides a motor shorting prevention part connected to a resistor and a heat sink for easily dissipating heat generated by a resistor.
즉, 본 고안은 상기와 같은 목적들을 달성키 위하여, 커넥터 하우징에 수직으로 착설하고 있는 전원단자 상단에 저항체를 코일상으로 하여 단자에 연결시키고 있는 구조의 저항기에 있어서, 세라믹재질의 기판 표면상에 도체도료로써 실크인쇄함에 의해 연결단을 갖는 저항체인 저항회로를 박층(薄層)으로 형성하여, 그 저항회로의 각 연결단 일측면 부위를 커넥터 하우징 상면에 돌설된 단자 상단과 접하게 하여 각각 응착하며, 기판 후면에는 일측면에 요철조(凹凸)를 이루는 방열판을 착설하여 방열과 아울러 기판을 지지토록 하고, 저항회로에는 단락부를 형성하여 저항기 과열시 자동 단락되게 한 모우터의 회전속도 조정용 저항기이다.That is, in order to achieve the above objects, the present invention is a resistor of a structure in which a resistor is connected to a terminal on a top of a power terminal mounted vertically to a connector housing in the form of a coil, on a substrate surface of a ceramic material. By printing silk as a conductor paint, a resistance circuit having a connection end is formed in a thin layer, and one side of each connection end of the resistance circuit is brought into contact with the upper end of the terminal protruding on the connector housing. On the back side of the board It is a resistor for adjusting the rotational speed of a motor that installs a heat sink to support heat dissipation and supports a substrate, and forms a short circuit in a resistance circuit so that a short circuit occurs automatically when the resistor is overheated.
이하, 첨부된 도면에 의거 본 고안의 기술구성 및 작용효과를 상술(祥述)하면 다음과 같다.Hereinafter, the technical configuration and the effect of the present invention based on the accompanying drawings in detail (祥 述) as follows.
다음 실시예에 의거 본 고안이 결코 한정되는 것은 아니다. 제1도 내지 제4도에 표시한 바와 같이. 도면 지시 부호(1)은 본원 고안의 저항기를 표시한 것으로, 하부의 기대(基台)로 되는 커넥터 하우징(2)에는 수개의 단자(4)...가 일정간격을 두고 배치되어 입실되며, 상기 단자(4)... 일부는 커넥터 하우징(2) 상면으로 돌출되고, 또 다른 일부는 커넥터 하우징(2)의 하부내로 연장된다(제3도 및 제4도).The present invention is by no means limited to the following examples. As shown in FIGS. 1 to 4. Reference numeral 1 denotes a resistor of the present invention, and several terminals 4 are arranged at a predetermined interval in the connector housing 2 which is a base of the lower part, The terminal 4... Part protrudes into the upper surface of the connector housing 2, and another part extends into the lower part of the connector housing 2 (FIGS. 3 and 4).
커넥터 하우징(2)의 하부내로 연장된 단자(4)...는 모우터(미도시)와 연결되는 전원부와 접속되며, 커넥터하우징(2) 상면으로 돌출되어 있는 단자(4)...들은 후술하는 기판(6)상에 저항체로 형성된 저항회로(8)의 각 연결판(a1)...에 땜납에 의해 응착된다.Terminals (4) ... extending into the lower part of the connector housing (2) are connected to the power supply connected to the motor (not shown), the terminals (4) ... protruding to the upper surface of the connector housing (2) It is adhered by soldering to each connecting plate a1 ... of the resistance circuit 8 formed of a resistor on the substrate 6 described later.
즉, 세라믹재질의 기판(6) 일측전(全) 표면에 걸쳐 도체도료를 사용하여 실크인쇄를 행함에 의해, 연결단(a1)... 를 갖는 저항회로(8)가 박층(薄層)으로 형성되며(제3도), 이렇게 구성된 기판(6)을 단자(4)... 에 대해 수직으로 입설하여 연결단(a1)...을 단자(4)... 의 일측면에 당접되게 한후, 당접부위를 땜납으로 응착시키는 것이다.That is, the silk circuit is printed using a conductive paint on one surface of the front surface of the ceramic substrate 6 so that the resistive circuit 8 having the connecting ends a1 ... is thin. (Fig. 3), the substrate 6 thus constructed is placed vertically with respect to the terminal 4, so that the connecting end a1 ... is abutted on one side of the terminal 4 ... After that, the contact is bonded with solder.
상기한 기판(6)후면에는, 기판(6)을 지지토록 함과 아울러 기판(6)에 형성된 저항회로(8)로부터 발열되는 열을 쉽게 외부로 방열토록 하기위해, 일측면에 요철조(凹凸)(12)를 형성한 알루미늄재질의 방열판(14)을 부착하고. 그 방열판(14)은 하우징(2) 몸체에 고정나사(10)를 이용하여 고정시킨다.On the back surface of the substrate 6, an uneven surface is formed on one side in order to support the substrate 6 and to easily dissipate heat generated from the resistance circuit 8 formed in the substrate 6 to the outside. A heat sink 14 made of aluminum is formed. The heat dissipating plate 14 is fixed to the housing 2 body using a fixing screw 10.
또, 저항회로(8)에는 저항회로(8)가 일정온도(대략 150℃)이상으로 발열되면 자동 용융되어서 단락되게 한 단락부(16)를 형성함에 의해, 저항회로(8)의 심한 과열로 인한 부하가 저항기(1)와 접속되는 모우터로 전달됨으로써 모우터를 소손되게 하는 것을 방지토록 하였다.In the resistance circuit 8, when the resistance circuit 8 generates heat above a predetermined temperature (approximately 150 ° C.), a short circuit portion 16 is automatically melted and short-circuited, thereby causing severe overheating of the resistance circuit 8. The resulting load was transferred to the motor connected with the resistor 1 to prevent the motor from being burned out.
도면중 미설명부호인 (18)은 저항기(1)의 고정구멍을 표시한 것이다.In the figure, reference numeral 18 denotes a fixing hole of the resistor 1.
이상의 기술구성에서 설명한 바와 같이, 본 고안의 저항기(1)는 저항회로(8)를 기판(6) 표면에 박층으로 형성하여 저항체를 구성하고 있기 때문에(제3도), 종래의 저항체를 열전도율이 높은 금속(철선) 코일로 형성한 것에 비해, 외부로의 열발생율이 현저히 저하되므로 자동차에 사용하는 경우에는 저항기(1)의 근접 배치된 부품들에 하등 악영향을 주지 않으며 또 저항기(1)의 근접 배치된 부품들에 하등 악영향을 주지 않으며 또 저항기(1) 차체로 과열로 인해 손상되는 율이 적어 오래동안 사용할 수가 있다고 하는 효과가 있다.As described in the above technical configuration, the resistor 1 of the present invention forms a resistor by forming the resistor circuit 8 in a thin layer on the surface of the substrate 6 (FIG. 3). Compared with a high metal (iron) coil, the rate of heat generation to the outside is considerably lowered. Therefore, when used in automobiles, it does not adversely affect the parts disposed close to the resistor 1 and also the proximity of the resistor 1. It does not adversely affect the disposed parts, and has the effect that it can be used for a long time due to the low rate of damage due to overheating to the resistor (1) body.
또한, 저항기(1) 제조에 있어서도 저항체를 기판(6)으로 형성하므로 인해, 종래 수개의 코일을 단자에 각각 연결하여 구성하는 것에 비하여, 저항기(1) 몸체를 감단하고 콤팩트하게 안가(安價)로 제조 공급할 수가 있다.In addition, in the manufacture of the resistor 1, since the resistor is formed of the substrate 6, the resistor 1 body is reduced and compactly compared to a structure in which several coils are connected to the terminals, respectively. Can be manufactured and supplied.
한편, 기판(6)상의 저항회로(8)가 정격 저항치 이상(150℃)으로 과열(OVER HEAT)될시에는 그 저항회로(8)에 형성한 단락부(16)가 자동 용융되어지므로, 저항기(1)로부터 모우터(미도시) 측으로의 부하가 걸리게 되는 것을 사전방지하여 모우터 소손을 없도록 하였다. 단락부(16)가 용융되면 기판(6)만을 교체하는 것에 의해 저항기(1)의 재사용이 가능하다.On the other hand, when the resistance circuit 8 on the substrate 6 is overheated beyond the rated resistance value (150 ° C.), the short circuit portion 16 formed in the resistance circuit 8 is automatically melted, so that the resistor The load on the motor (not shown) from (1) was prevented in advance so that the motor was not burned out. When the short circuit 16 is melted, it is possible to reuse the resistor 1 by replacing only the substrate 6.
또, 방열판(14)은 기판(6)의 저항회로(8)로부터 발생되는 열은 외부로 방열되게 하며, 다른 한편으로는 기판(6)의 견고한 보강 역활을 도모하여 기판(6)이 쉽게 단자(4)... 로부터 탈리됨을 방지하는 등의 효과가 있는 우수한 고안이다.In addition, the heat dissipation plate 14 allows heat generated from the resistance circuit 8 of the substrate 6 to radiate to the outside. (4) It is an excellent design with the effect of preventing detachment from.
