본 발명은 샤시면에 고정되는 단자받침대 및 이를 금속 제케이스에 고정시키는 방법에 관한 것이다.The present invention relates to a terminal support fixed to the chassis surface and a method of fixing it to a metal case.

단자받침대는 샤시면, 예를들면 금속제 판금케이스나 블래킷류의 외측면과 내측면 혹은 전면과 후면간의 전기접속의 행함에 있어서 단자와 금속제케이스를 절연시키게 고정되어야 하며 또한 임의위치에 고정될 수 있어야 하고 고정상태가 견고하여 유동이 없고 밀착상태가 양호하게 고정되어야 한다.The terminal stand shall be fixed to insulate the terminal and the metal case from the chassis surface, for example, in the electrical connection between the outer and inner surfaces of the metal sheet metal case or bracket or between the front and rear sides, and may be fixed in any position It should be firmly fixed and have no flow and tight adhesion.

금속제케이스에 고정되는 종래의 단자받침대가 제 1 도에 도시되는데, 단자받침대(1)는 내측단자(2)를 내측단자받침대(3)에 설치하고 이들에 아이렛(4)을 끼운다음 이 조립물을 케이스구멍(5)에 끼워맞추고 내측단자받침대(3)의 돌출견부(6)에 고무패킹(7)을 끼워넣고 그 위에 차례로 외측단자받침대(8)와 외측단자(9)를 끼워맞추며 아이렛(4)의 외측단부를 프레스나 리셋팅머신으로 리벳팅하여 조립된다. 이러한 종래의 단자받침대는 많은 부품이 소요되므로 작업시간이 길고 불량발생시 손실이 크며 제조원가가 비싸지는 결점이 있다.A conventional terminal support fixed to a metal case is shown in FIG. 1, in which the terminal support 1 is provided with an inner terminal 2 on the inner terminal support 3, an eyelet 4 fitted therein, and then the assembly. To the case hole (5), the rubber packing (7) is inserted into the protruding shoulder (6) of the inner terminal support (3), and the outer terminal support (8) and the outer terminal (9) in turn on the eyelet ( It is assembled by riveting the outer end of 4) by pressing or resetting machine Since the conventional terminal support takes many parts, there is a drawback in that the working time is long, the loss is large, and the manufacturing cost is high.

본 발명의 목적은 이러한 결점을 제거하기 위하여 구조를 간단히 하여 작업시간이 단축되게 구성된 단자받침대를 제공하고자 하는 것이다. 또한 본 발명의 다른 목적은 단자받침대를 스웨이징하여 간단히 금속제케이스에 고정시키는 방법을 제공하고자 하는 것이다.It is an object of the present invention to provide a terminal stand configured to simplify the structure and to reduce the working time in order to eliminate this drawback. In addition, another object of the present invention is to provide a method of simply swaging the terminal support to a metal case.

본 발명을 첨부된 도면을 참조하여 하기에 설명한다. 제 2 도에는 본 발명의 단자받침대가 도시되는데, 단자받침대(10)는 사출물(11)과 그 중앙에 위치한 단자(12)로 형성되는 사출물이다. 사출물(11)은 사각형판(13)과 그 외측으로 돌출된 환상돌기부(14)를 가지며, 환상돌기부(14)의 외경은 금속제케이스(15)의 케이스구멍(16)의 내경과 같다.The present invention is described below with reference to the accompanying drawings. 2 shows a terminal stand of the present invention, wherein the terminal stand 10 is an injection molded product formed of an injection material 11 and a terminal 12 located at the center thereof. The injection molded product 11 has a rectangular plate 13 and an annular protrusion 14 protruding outward, and the outer diameter of the annular protrusion 14 is equal to the inner diameter of the case hole 16 of the metal case 15.

제 3 도는 제 2 도의 단자받침대의 단면도가 도시되는데, 단자(12)는 외측에 외측단자(17)와 내측에 내측단자(18)를 가지며, 내측단자(18)는 가지부(19) 및 (20)로 나누어지고 이들사이에는 원형홈(21)이 형성된다3 is a cross-sectional view of the terminal stand of FIG. 2, wherein the terminal 12 has an outer terminal 17 on the outside and an inner terminal 18 on the inside, and the inner terminal 18 has branches 19 and ( 20) and circular grooves 21 are formed therebetween.

본 발명의 단자받침대를 금속제케이스에 고정시키는 방법은 다음과 같다.The method for fixing the terminal stand of the present invention to a metal case is as follows.

단자 받침대(10)를 금속제케이스(15)에 고정시키려면, 사출물(11)의 환상돌기부(14)를 금속제케이스(15)의 케이스구멍(16)에 삽입하고, 금속제케이스(15)의 내부에서 단자받침대(10)를 지지하는 상태에서 외측에서 초음파 용착기를 이용하여 환상돌기부(14)를 초음파용착기의 혼으로 스웨이징하면, 환상돌기부(14)는 제 3 도의 쇄선위치에서 실선위치로 용융되어 금속제케이스(15)의 케이스구멍(16)의 가장자리에 덮히게되고 단자받침대(10)는 금속제케이스(15)에 고정된다.To fix the terminal pedestal 10 to the metal case 15, the annular projection 14 of the injection molded product 11 is inserted into the case hole 16 of the metal case 15, and the inside of the metal case 15 If the annular protrusion 14 is swung out of the ultrasonic welding machine by the horn of the ultrasonic welding machine using an ultrasonic welding machine from the outside while supporting the terminal support 10, the annular protrusion 14 is melted to the solid line position in the dashed line position of FIG. The edge of the case hole 16 of the case 15 is covered and the terminal stand 10 is fixed to the metal case 15.

다음에는 단자받침대(10)의 내측단자(18)의 원형홈(21)내부에 와이어를 삽입시키고 가지부(19) 및 (20)를 니퍼등에 의해서 오무려서 원형홈(21)속에 와이어가 견고하게 고정되게 한다. 그후에는 와이어를 내측단자(18)에 납땜한다.Next, the wire is inserted into the circular groove 21 of the inner terminal 18 of the terminal support 10, and the branches 19 and 20 are pinched by a nipper or the like to secure the wire in the circular groove 21. To be fixed. Thereafter, the wire is soldered to the inner terminal 18.

상기와 같이 구성된 본 발명의 단자받침대를 종래의 단자받침대에 비해서 구조가 간단하여 부품의 수가 현저히 줄어들며 조립하는데 필요한 시간이 절감되는 효과를 제공한다.The terminal stand of the present invention configured as described above has a simple structure compared to the conventional terminal stand, thereby significantly reducing the number of parts and providing an effect of reducing the time required for assembly.

또한 본 발명의 단자받침대를 금속제케이스에 고정시키는 방법은 단자받침대(10)의 환상돌기부(14)를 초음파용착기에 의해서 스웨이징하여 금속제케이스(15)에 간단히 고정시킬 수 있으므로 대량생산에 알맞게 자동화가 가능한 효과가 있다.In addition, the method of fixing the terminal stand of the present invention to the metal case can be easily fixed to the metal case 15 by swaging the annular protrusion 14 of the terminal stand 10 by the ultrasonic welding machine, so that the automation is suitable for mass production. There is a possible effect.
