배터리 단자를 포함하는 배터리 리드 구조{BATTERY LID STRUCTURE COMPRISING A BATTERY TERMINAL}Battery lead structure with battery terminals {BATTERY LID STRUCTURE COMPRISING A BATTERY TERMINAL}

본 발명은 배터리 단자를 포함하는 배터리 리드 구조, 특히 액체 전해질 배터리를 위한 배터리 리드 구조에 관한 것이다.The present invention relates to a battery lead structure comprising a battery terminal, in particular a battery lead structure for a liquid electrolyte battery.

예컨대 DE 10 2005 030 992 A1, DE 41 27 956 B4, DE 103 01 043 B3, DE 689 10 878 T2, DE 689 13 339 T2, DE 198 60 198 C2, DE 34 17 521 C2, DE 696 12 537 T2와 같은 종래 기술로부터 다수의 배터리 단자 구조가 공지되어 있다. 이러한 배터리 단자 구조들은 액체 및 기체에 대해 밀폐성을 가지도록 설계되었다.For example, DE 10 2005 030 992 A1, DE 41 27 956 B4, DE 103 01 043 B3, DE 689 10 878 T2, DE 689 13 339 T2, DE 198 60 198 C2, DE 34 17 521 C2, DE 696 12 537 T2 and Many battery terminal structures are known from the same prior art. These battery terminal structures are designed to be sealed against liquids and gases.

또한, 배터리 단자에 센서 혹은 측정 라인이 배치되는 것도 공지되어 있다. 이와 관련하여 다음과 같은 근본적인 문제점들이 나타난다. 즉 센서 혹은 측정 라인이 배터리 단자에 연결되는 접촉 지점은 우수하게 보호되어야 한다. 이러한 보호는 화학적 영향 및 기계적 영향과 관련이 있다. 예컨대 공격적인 전해질이 접촉 지점에 도달하면, 부식에 의해 추가적인 전기적 저항이 발생하고, 이는 측정 결과를 왜곡한다. 또한, 부식으로 인해 접촉 지점의 기계적 안전성이 감소하고, 그럼으로써 근소한 기계적 부하에도 측정 라인이 끊어질 수 있다. It is also known to arrange sensors or measuring lines at the battery terminals. The following fundamental problems appear in this regard. That is, the point of contact at which the sensor or measuring line is connected to the battery terminals must be well protected. This protection is related to chemical and mechanical effects. For example, when an aggressive electrolyte reaches the point of contact, corrosion creates additional electrical resistance, which distorts the measurement results. Corrosion also reduces the mechanical safety of the contact points, which can result in breakage of the measuring line even with slight mechanical loads.

또한, 기계적 손상에 대한 보호도 필요하다. 실제로 그러한 배터리들은 고압 워터 제트(water jet)로도 청소가 되며, 그로 인해 접촉 지점이 손상되어서는 안 되기 때문이다. There is also a need for protection against mechanical damage. In fact, such batteries are also cleaned with a high pressure water jet, so that the contact points must not be damaged.

DE 199 61 311 A1, DE 101 18 051 A1, DE 35 32 044 A1, DE 696 16 306 T2, US 45 72 878, EP 12 04 165 A1, WO 99/54 744 A1에는 추가적인 연결 라인 혹은 센서를 포함하는 배터리 단자들이 공지되었다. 이 인용 문헌들은 구조상 공간이 근소해야 하는 경우에, 공격적인 매질 및 기계적 손상으로부터 보호해야하는 요구를 잘 충족시키기가 근본적으로 힘들다는 것을 보여준다. 특히 표준 배터리에서 하우징 및 전극 패키지의 용적을 포괄적으로 유지해야 하는 경우에 이러한 요구를 충족하기가 어렵다.DE 199 61 311 A1, DE 101 18 051 A1, DE 35 32 044 A1, DE 696 16 306 T2, US 45 72 878, EP 12 04 165 A1, WO 99/54 744 A1 contain additional connection lines or sensors Battery terminals are known. These cited references show that where structural space is sparse, it is fundamentally difficult to meet the demands of protection from aggressive media and mechanical damage. This requirement is difficult to meet, especially when the volume of housing and electrode packages must be comprehensively maintained in standard batteries.

따라서, 본 발명의 과제는 측정 라인과 연결되어 있는 배터리 단자를 기계적 손상과 습기로부터 신뢰성있게 보호하는 것을 보장하는 배터리 단자 구조를 제공하는 데에 있다. 특별히 달성해야 하는 요구 사항은 그러한 보호가 비용면에서 경제적이어야 하며, 종래의 배터리 단자 구조에 비해 본질적인 변경의 필요성이 제거되어야 한다는 점이다.Accordingly, an object of the present invention is to provide a battery terminal structure that ensures reliable protection of the battery terminals connected to the measurement line from mechanical damage and moisture. A particular requirement to be achieved is that such protection must be economical in terms of cost and the need for intrinsic changes compared to conventional battery terminal structures must be eliminated.

이러한 과제는 특허 청구항 1에 따라 배터리 단자를 포함하는 배터리 리드 구조에 의해 달성된다. This problem is achieved by a battery lead structure comprising a battery terminal according to patent claim 1.

다음의 설명은 하나의 배터리 단자 및 이것을 배터리 리드에 배치하는 것에 관한 것이며, 배터리 리드에 다수의 배터리 단자가 배치된다 하더라도 이는 동일한 방식으로 실시된다. The following description relates to one battery terminal and its placement on the battery lead, even if multiple battery terminals are disposed on the battery lead.

배터리 리드에 배터리 단자가 배치되고 기존의 방식으로 고정되되, 예컨대 형태 결합되는 방식으로 끼워진다. 배터리 단자에는 적어도 하나의 측정 단자 부분(measuring terminal section)이 제공되고, 이 측정 단자 부분은 배터리 단자로부터 돌출되어 측면 방향에서 배터리 리드 평면으로 연장된다. 이러한 측정 단자 부분에 측정 라인이 종래의 방식으로 연결될 수 있다. 배터리 단자를 중심으로 배터리 리드에 편평한 리세스부(recess)가 제공되며, 이 리세스부는 덮개로 덮인다. 이 리세스부 내에 측정 단자 부분이 놓인다. 리세스부는 탄성 실링재(sealing material)로 채워진다. 그럼으로써 측정 단자 부분, 측정 라인의 일부분, 그리고 특히 측정 라인이 측정 단자 부분과 연결되는 접촉 지점이 탄성 실링재에 의해 둘러싸이고 수분과 습기로부터 우수하게 보호된다. 그러한 실링재는 당업자에게 공지되어 있고, 따라서 제품명을 언급할 필요가 없다. 이러한 실링재의 탄성을 바탕으로 온도 변화 시에도, 예컨대 공격적인 전해질이 침투할 수 있는 균열이 발생하지 않는다. 이러한 위험은 상대적으로 더욱 높은 기계적 안정성을 보유한 단단한 접합 화합물(jointing compound)에서 발생한다. 따라서 덮개는 안정적인 재료, 바람직하게는 플라스틱을 포함하는 재료로 형성되고 편평한 리세스부를 덮는 덮개를 구비하되, 덮개는 고압 워터 제트 혹은 덮개에 닿는 공구, 예컨대 드라이버가 손상을 일으키지 않도록 치수화된다.The battery terminals are arranged on the battery leads and fixed in a conventional manner, for example fitted in a formally coupled manner. The battery terminal is provided with at least one measuring terminal section which protrudes from the battery terminal and extends in the lateral direction to the battery lead plane. The measuring line can be connected to this measuring terminal part in a conventional manner. A flat recess is provided in the battery lead around the battery terminal, which is covered by a cover. The measurement terminal part is placed in this recess. The recess portion is filled with an elastic sealing material. Thereby the measuring terminal part, part of the measuring line and in particular the contact point where the measuring line is connected with the measuring terminal part are surrounded by the elastic sealing material and are well protected from moisture and moisture. Such sealing materials are known to those skilled in the art and, therefore, need not mention product names. On the basis of the elasticity of such a sealing material, even at temperature changes, for example, cracks that can penetrate aggressive electrolytes do not occur. This risk arises from rigid jointing compounds with relatively higher mechanical stability. The lid is thus formed of a stable material, preferably a material comprising plastic, and has a lid covering the flat recess, wherein the lid is dimensioned so as not to damage the high pressure water jet or the tool, such as a driver, that comes in contact with the lid.

특허 청구항 제 2항에 따르면 덮개는 클립 홀더에 의해 리세스부에 고정될 수 있다. 이러한 클립 홀더는 리드 제조 시에 경량 구조로 그리고 적은 비용으로 제조 가능하며, 고정의 신뢰성이 높고 밀폐성이 우수하다. According to claim 2, the lid can be fixed to the recess by the clip holder. Such clip holders can be manufactured in a lightweight construction and at low cost in the manufacture of leads, and are highly reliable in fixing and excellent in sealing.

특허 청구항 제 3항에 따르면, 덮개는 접착 테이프로 리세스부에 고정된다. 특허 청구항 제 2항에 따른 실시예에 대한 이러한 대안은 특히 비용 면에서 경제적이다. According to claim 3, the lid is fixed to the recess with adhesive tape. This alternative to the embodiment according to claim 2 is particularly economical in terms of cost.

본 발명에 의하면, 측정 라인과 연결되어 있는 배터리 단자를 기계적 손상과 습기로부터 신뢰성있게 보호하는 것을 보장하는 배터리 단자 구조를 제공할 수 있다.According to the present invention, it is possible to provide a battery terminal structure that ensures reliable protection of the battery terminals connected to the measurement line from mechanical damage and moisture.

본 발명은 다음에서 실시예와 도면을 참조하여 이하에 설명된다.The invention is explained below with reference to the embodiments and the drawings in the following.

배터리 리드(2)에 배터리 단자(1)가 형태 결합되는 방식으로 고정된다. 본 실시예에서 배터리 단자(1)에 2개의 측정 단자 부분(1c1, 1c2)이 제공되고, 이 부분에 각각 하나의 측정 라인이 예컨대 납땜, 용접 혹은 조임 나사를 이용하여 연결될 수 있다. 배터리 단자(1)를 중심으로 배터리 리드(2)에 편평한 리세스부(3)가 제공되고, 이 리세스부(3)는 덮개(4)로 덮인다. 측정 단자 부분(1c1, 1c2)은 서로 마주보고 있으며 이 리세스부 내에 수평으로 놓여 연장된다. 리세스부(3)는 바람직하게는 탄성 실링재로 완전히 채워지고, 그럼으로써 측정 단자 부분(1c1, 1c2)이 실링재 내에 완전히 묻히어 수분 및 공격적인 습기로부터 보호된다. 덮개(4)는 바람직하게는 배터리 리드(2) 자체와 동일한 물질로 제조되고, 그럼으로써 기계적 부하에 대해 안전한 보호를 보장한다. 가장자리 면의 클립 홀더(5)는 덮개(4)가 리세스부(3)에 매우 안전하게 결합되도록 보장한다. 공동부(6)를 통해 측정 라인(미도시)이 설치될 수 있다. The battery terminals 1 are fixed to the battery leads 2 in a form-coupled manner. In the present embodiment, two measuring terminal portions 1c 1 , 1c 2 are provided in the battery terminal 1 , in which one measuring line can be connected, for example, using soldering, welding or tightening screws. A flat recess 3 is provided in the battery lead 2 around the battery terminal 1, which is covered with a lid 4. The measuring terminal portions 1c 1 , 1c 2 face each other and extend horizontally within this recess. The recess 3 is preferably completely filled with an elastic sealing material, so that the measuring terminal portions 1c 1 , 1c 2 are completely buried in the sealing material and protected from moisture and aggressive moisture. The lid 4 is preferably made of the same material as the battery lead 2 itself, thereby ensuring safe protection against mechanical loads. The clip holder 5 on the edge face ensures that the lid 4 is very securely fitted to the recess 3. A measuring line (not shown) can be installed through the cavity 6.

전술한 실시예는 본 발명의 가장 우수한 실시예이다. 전술한 실시예를 바탕으로하여 당업자는 본 발명의 기술적 이론을 완전하게 추론할 수 있다. 본 실시예가 당업자에 의해 본 발명에 따른 이론을 이용하여 계속적으로 발전 및 수정되거나 조합될 수 있다는 점은 분명하다. 따라서 명확하게 언급되지 않았거나 도시되지 않은 추가적인 실시예도 다음의 특허 청구항의 보호 범위에 속한다.The above embodiment is the best embodiment of the present invention. Based on the above-described embodiments, those skilled in the art can fully deduce the technical theory of the present invention. It is clear that this embodiment may be continuously developed, modified or combined by one skilled in the art using the theory according to the present invention.
