Description

소형 모우터의 단자캠Terminal Cam of Small Motor

제1도는 본 고안이 실시된 모우터의 분해 사시도.1 is an exploded perspective view of a motor in which the present invention is implemented.

제2도는 본 고안의 접속단자와 브러시의 결속상태를 나타낸 단면도.2 is a cross-sectional view showing the binding state of the connection terminal and the brush of the present invention.

제3a도, 제3b도는 본 고안과 종래의 단자캡을 비교 도시한 저면도.Figure 3a, Figure 3b is a bottom view comparing the present invention and the conventional terminal cap.

제4도는 종래의 접속단자와 브러시의 분해사시도.4 is an exploded perspective view of a conventional connecting terminal and a brush.

본 고안은 휴대용 가전제품등에 널리 사용되는 소형 모우터의 접속단자와 브러시의 상호 결속을 강화함으로써 종래 이들의 비합리적 구조결합으로 인해 접속단자와 브러시가 해리되어 못쓰게 되던 폐단을 없에고 이에 수반되던 사용상의 위험부담 등을 덜어 안전도를 높이는 것을 주골자로 하여 안출된 소형 모우터의 단자캡에 관한 것이다.The present invention reinforces the cohesion between the connection terminal and the brush of a small motor widely used in portable home appliances, etc., thereby eliminating the discontinuity caused by disassociation of the connection terminal and the brush due to their irrational structural coupling, and accompanying the danger of use. The present invention relates to a terminal cap of a small motor designed to reduce safety and increase safety.

본 고안과 같이 합성수지제로 된 종래의 단자캠(제3b도)에는 크고작은 세 개의 내외돌기(3'a), (6)가 있고 이 돌기들사이에 텐숀(Tension)이 주어진 채로 브러시(5a)가 고정되며, 접속단자(4a)는 내측돌기(3a')와 브러시(5a)의 협지부사이에 끼이고 그 인발턱(4a')이 브러시의 협지부에 나있는 괘공(5a')에 걸리도록 구성되어 있는데, 접속단자에 전선을 이으려고 납땜질 할 때는 높은 인두열 때문에 수지로 된 단자캠의 단자삽입공 주위는 녹아서 넓어지고 0.1㎜내외의 두께를 갖는 얇은 인동판으로 된 브러시에는 소성변형이 일어나 탄성이 줄고 현상이 변해서 접속단자를 누르고 있던 힘이 약해지므로 생산단계에서부터 접속단자가 아예 빠져버려 불량품이 되고 말거나 헐겁게 조립되어 불안한 요소를 간직한채 출고되는 일이 흔한데, 이러한 사례는 생산에 직접 참여하는 종사자가 미숙할수록 더욱 심하다. 그래서 납땜질을 할 때에는 매우 신중을 기해야 하고 또 그만큼 작업도 까다롭다.In the conventional terminal cam (Fig. 3b) made of synthetic resin as described in the present invention, there are three large and small inner and outer protrusions 3'a and 6, and the brush 5a is given a tension between the protrusions. Is fixed, and the connection terminal 4a is sandwiched between the inner projection 3a 'and the clamping portion of the brush 5a, and the drawing jaw 4a' is caught by the hanging hole 5a 'extending from the clamping portion of the brush. When soldering to connect the wires to the connection terminal, the high iron heat causes melt around the terminal insertion hole of the resin terminal cam, and widens the plastic deformation of the brush made of thin copper plate with a thickness of about 0.1mm. As this happens, the elasticity decreases and the phenomenon changes, and the force holding the connection terminal is weakened. Therefore, the connection terminal is completely lost from the production stage and becomes a defective product, or is loosely assembled and shipped with unstable elements. Oh yeah The more immature workers are, the worse. So you have to be very careful when soldering and it's a lot of work.

본 고안은 이와같이 접속단자가 헐거워 사용하기 불안하다거나 빠져 못쓰게 되는 폐단을 일소하는 한편 간편하게 조립생산할수 있는 편리를 도모하고자 안출한 것으로서 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised to purify the convenience of easy assembly and production, while at the same time loosening the connection terminal is unstable to use or loose, as described in detail based on the accompanying drawings as follows.

아마튜어(2)를 내장한 모우터케이스(1)와 이 상단에 결합될 단자캠(3)저면 내측에는 협지돌기(3')가 있고 여 기에 접속단자(4)와 브러시(5)가 협상 고정된 공지에 있어서, 접속단자(4)를 U자형으로 절곡하여 공지의 브러시(5)를 끼운후 협지돌기(3')와 주벽사이의 삽통공(3')으로 집어넣고 단자캠(3)상 표면으로 노출된 절곡편(4')의 선단부(4")를 캡표면에 밀착되게 절곡시켜 본 고안을 구성한다.There is a motor case (1) having a built-in armature (2) and a pinch protrusion (3 ') inside the bottom of the terminal cam (3) to be coupled to the upper end, where the connecting terminal (4) and the brush (5) are negotiated. In a fixed known manner, the connecting terminal 4 is bent into a U-shape to insert a well-known brush 5 and then inserted into the insertion hole 3 'between the pinching protrusion 3' and the circumferential wall and the terminal cam 3 The tip 4 'of the bent piece 4' exposed to the upper surface is bent in close contact with the cap surface to constitute the present invention.

이와같이 구성된 본 고안은 제2도에서 볼수 있는 바와같이 안쪽에서는 브러시(5)에 U절곡부가 걸려 있어서 접속단자(4)가 밖으로 빠질수 없고 밖에서는 절곡편(4')노출 선단부(4")가 단자캡(3)상 표면에 꽉 겹쳐 물려져 있어 서 안으로도 빠지지 않는다.As can be seen in FIG. 2, the present invention configured as described above has a U-bending portion hanging from the brush 5 so that the connecting terminal 4 cannot be pulled out and the bending piece 4 'exposed tip 4 " The cap (3) is tightly overlaid on the surface and does not fall inside.

이러한 구조적 특징이 있음으로 해서 납땜질할 때 설혹 필요이상의 인두열이 접속단자에 전달되어 수지제 단자캡의 삽통공 부위가 녹고 브러시가 소성변형을 일으키는 일이 있더라도 이에 아무런 구애도 받지 않고 본래의 견고한 결속상태가 보존되며, 브러시에 텐숀이 부여되지 않은채 자연상태로 결합이 가능할분 아니라 접접속단자와 브러시에다가 결합에 필요한 부수적인형상을 부여할 필요없이 단순한 절곡에 의해서 용이하게 소기한 목적을 달성할수 있는 등 제작면으로도 수월한 점이 많다.Due to this structural feature, even more than necessary iron heat is transferred to the connection terminal when soldering, so that the insertion hole portion of the resin terminal cap melts and the brush may cause plastic deformation. The binding state is preserved, and it is not possible to combine in the natural state without tension applied to the brush, and easily achieves the desired purpose by simple bending without providing the connecting terminal and the brush with additional shapes necessary for the connection. There are a lot of things that are easy to make.

협지돌기(3')와 삽통공(3")에 의해서 브러시(5)와 접속단자(4)를 부착고정시킨 공지에 있어서, 접속단자(4)를 U자형상으로 하여 절곡편(4')을 형성하고 이 절곡부에 공지의 브러시(5)를 끼워 협착시켜 삽통공에 꿴 후 캡(3)표면으로 노출된 선단부(4")를 절곡 밀착시켜서 된 소형 모우터의 단자캡.In the known technique in which the brush 5 and the connecting terminal 4 are fixed to each other by the pinching protrusion 3 'and the insertion hole 3 ", the bent piece 4' is formed by making the connecting terminal 4 U-shaped. The terminal cap of the small motor, which is formed by inserting a well-known brush (5) into the bent portion and squeezing it into the insertion hole and bending the tip portion (4 ") exposed to the surface of the cap (3).
