Abstract

A heating assembly for a PTC(Positive Temperature Coefficient) heater is provided to prevent PTC elements installed within a heating rod from falling off, and to assemble the PTC elements without another assembling jig, then to sufficiently contact the PTC elements with a contact path, thereby improving the performance of a PTC heater. PTC elements(10) are combined on one side of a conductive contact path(20). The conductive contact path(20) conducts the PTC elements(10). An insulator(30) insulates other side of the conductive contact path(20). A heating rod(40) is inserted and fixed by the PTC elements(10), the contact path(20), and the insulator(30). When the PTC elements(10) are inserted into the heating rod(40) while being combined with the contact path(20), elastic portions maintain a firmly fixed state of the contact path(20) within the heating rod(40) without moving the contact path(20).

이하에서는 본 발명의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 PTC 히터용 히팅 조립체의 분리 사시도이고, 도 3은 도 2의 A부에 대한 부분 확대도이다.2 is an exploded perspective view of a heating assembly for a PTC heater according to the present invention, Figure 3 is a partially enlarged view of a portion A of FIG.

도시된 바와 같이, 본 발명의 히팅 조립체는, 종래의 PTC 소자 고정용 프레임이 배제되고, PTC 소자(10)와, 이 PTC 소자(10)가 일측면에 결합됨과 아울러 PTC 소자(10)에 통전을 시키는 통전용 접속 단자(20), 이 접속 단자(20)의 타측면을 절연시키는 절연체(30), 그리고 이들 요소들이 삽입 고정되는 히팅 로드(40)로 이루어져 있다.As shown in the drawing, the heating assembly of the present invention eliminates the conventional PTC element fixing frame, and the PTC element 10 and the PTC element 10 are coupled to one side and energized by the PTC element 10. It consists of a connection terminal 20 for power transmission, an insulator 30 for insulating the other side of the connection terminal 20, and a heating rod 40 into which these elements are inserted and fixed.

특히, 상기 접속 단자(20)의 PTC 소자(10)가 결합된 일측면과 그 반대면에 각각 탄성부(20b,20c)가 돌출 형성되어 있는데, 이 탄성부(20b,20c)는 PTC 소자(10)가 접속 단자(20)에 결합된 상태에서 히팅 로드(40)에 삽입 되었을 때 접속 단자(20)가 히팅 로드(40) 내에서 유동되지 않고 견고한 고정 상태를 유지토록 하는 작용을 하게 된다. 더욱이, PTC 소자(10)가 결합된 일측면에서 돌출된 탄성부(20b)는 PTC 소자(10)의 두께보다 더 크게 돌출되는 것이 바람직하며, PTC 소자(10)가 결합된 일측면에서 돌출된 탄성부(20b)의 돌출 정도는 그 반대면에서 돌출된 탄성부(20c)의 돌출 정도보다 크게 하는 것이 바람직하다. 이러한 탄성부(20b,20c)는 접속 단자(20)의 중앙부로부터 양단부를 향해 등간격으로 두 군데 정도 형성되도록 하는 것이 접속 단자(20)의 균형적인 고정상태 유지를 위해 바람직할 것이다.Particularly, elastic portions 20b and 20c protrude from one side and the opposite surface to which the PTC element 10 of the connection terminal 20 is coupled, and the elastic portions 20b and 20c are PTC elements ( When 10) is inserted into the heating rod 40 in a state coupled to the connection terminal 20, the connection terminal 20 is not flowed in the heating rod 40 to act to maintain a firm fixed state. Furthermore, the elastic portion 20b protruding from one side to which the PTC element 10 is coupled is preferably protruded larger than the thickness of the PTC element 10, and protruding from one side to which the PTC element 10 is coupled. The degree of protrusion of the elastic portion 20b is preferably larger than the amount of protrusion of the elastic portion 20c protruding from the opposite side thereof. It is preferable that the elastic parts 20b and 20c be formed at two equal intervals from the center of the connection terminal 20 to both ends thereof in order to maintain a balanced fixed state of the connection terminal 20.

한편, PTC 소자(10)를 접속 단자(20)에 고정시키기 위한 수단으로서 다음과 같은 구조가 마련된다. 즉, PTC 소자(10)의 가운데 부분에 호울(10a)이 형성되고, 이에 대응하여 접속 단자(20)에도 호울이 형성되는데, 특히 접속 단자(20)의 호울에 버링(burring) 가공이 가해짐으로써 버링부(20a)가 형성되고, 이 버링부(20a)가 PTC 소자(10)의 호울(10a)에 끼워지게 되어 PTC 소자(10)가 접속 단자(20)에 견고하게 고정된다. 이에 따라, PTC 소자(10)가 접속 단자(20)와 긴밀하게 밀착됨과 아울러 일체로 결합이 된 상태를 유지하게 된다.On the other hand, as a means for fixing the PTC element 10 to the connection terminal 20, the following structure is provided. That is, the hole 10a is formed in the center part of the PTC element 10, and correspondingly, the hole is formed also in the connection terminal 20, In particular, the burring process is applied to the hole of the connection terminal 20. The burring part 20a is formed, and this burring part 20a is fitted to the hole 10a of the PTC element 10, and the PTC element 10 is firmly fixed to the connection terminal 20. As shown in FIG. As a result, the PTC element 10 is in close contact with the connection terminal 20 and maintains a state in which the PTC element 10 is integrally coupled.

이와 같이, 본 발명의 히팅 조립체에서는, PTC 소자(10)의 조립을 위한 종래의 프레임이 삭제되고, PTC 소자(10)가 접속 단자(20)에 직접 일체로 결합된 상태에서 접속 단자(20)에 형성된 탄성부(20b,20c)에 의해 탄성 지지되므로 PTC 소자(10)가 탈락될 우려는 없다. 또, PTC 소자(10)의 조립을 위한 별도의 조립용 지그가 불필요하게 되고, PTC 소자(10)를 접속 단자(20)에 충분히 밀착시킬 수 있게 된다.As described above, in the heating assembly of the present invention, the conventional frame for assembling the PTC element 10 is deleted, and the connection terminal 20 is in a state where the PTC element 10 is directly and integrally coupled to the connection terminal 20. Since it is elastically supported by the elastic parts 20b and 20c formed in the same, there is no possibility that the PTC element 10 may fall off. In addition, a separate assembly jig for assembling the PTC element 10 becomes unnecessary, and the PTC element 10 can be brought into close contact with the connection terminal 20 sufficiently.

이상에서 설명한 바와 같이, 본 발명에 따른 피티씨 히터용 히팅 조립체에 의하면, 별도의 PTC 소자 조립용 프레임과 지그가 불필요하게 되므로 비용 절감과 작업성 및 생산성 향상의 효과가 기대된다.As described above, according to the heating assembly for the PTC heater according to the present invention, since a separate PTC element assembly frame and jig is unnecessary, the effect of cost reduction, workability and productivity are expected.

또, PTC 소자가 통전용 접속 단자와 충분히 밀착 조립되므로 PTC 히터의 원활한 작동에 따른 성능 보전 및 향상의 효과도 기대된다.In addition, since the PTC element is sufficiently tightly assembled with the connection terminal for electricity supply, the effect of performance preservation and improvement by smooth operation of a PTC heater is also expected.
