一個可靠且穩固的電氣連接需要的不僅僅是電纜和連接器。根據實際的應用和工作環境，更好的解決方案可能是開發出插入式或二次成型插針的特殊連接。端子可以被二次成型塑料完全保護，二次成型的塑料選取特定的材料，以滿足機械性能或環境保護和空間限制等要求。
A reliable and robust electrical connection requires more than cables and connectors. Depending on the application and the environment, a better solution may be to develop special connections with inserted or overmolded pins. Electrical contacts can be totally protected by a plastic overmolding made from a material selected to meet mechanical or environmental protection and space constraints. The protective function of this overmolding feature is essential to ensure the reliability of the connection. Overmolding can also be an asset to adapt and facilitate the integration of the connection into the customer’s system.
//無連接器連接
Connecting without a connector
對于印刷電路板組件(PCBA)上的連接應用，通常會選用標準連接器，但根據尺寸和客戶的具體要求，提供定制的互連解決方案是很有必要的。
For connections on printed circuit board assemblies (PCBA), the use of standardized connectors is typical but, depending on the size and the specific customer requirements, customized interconnect solutions may be necessary.
//Pressfit端子
Unit pressfit contacts
電路板Pressfit端子解決方案便是這些解決方案其中之一。將具有壓接功能（端子上有針眼）的沖壓端子插入 PCB 的電鍍孔中，無需額外的焊接操作。這種插入操作可以通過將專用機器集成到裝配線中來實現自動化。
The pressfit contact solution on a circuit board is one of these solutions. A stamped contact with the pressfit function (eye-of-the-needle) is inserted into the plated hole of a PCB without the need for additional soldering operations. This insertion can be automated with the integration of dedicated machines into the assembly lines.
在該設計方案中，設計者可以根據應用所需的電流來定義端子的尺寸。不同厚度和鍍層的合格Pressfit產品可以滿足客戶的規格要求。然后將帶有Pressfit端子的PCBA組裝到塑料外殼中。這種解決方案降低了實現連接器的成本，并提供了一個完美的集成單元。
The design study allows the designer to define the size of the contact according to the current required for the application. Qualified pressfits of different thicknesses and platings are used to meet customer specifications. The PCBA with its pressfit contacts is then assembled into a plastic housing. This solution reduces the cost of the connector function and provides a perfectly integrated unit.
//二次成型Pressfit端子
Overmolded pressfit contacts
二次成型連接方案也可被用于滿足客戶的需求。與客戶的協同工程階段在產品定義中起著至關重要的作用:在流變學應用軟件的幫助下優化零件的幾何形狀，并根據各種條件要求選擇材料(PA、PBT、PPS、PPA等)。
Overmolded connections to fit the customer’s needs can also be considered. The co-engineering phase plays an essential role in the definition of the product: optimization of the geometry of the parts with the help of rheology software and choice of materials (PA, PBT, PPS, PPA, and others) in relation to the various constraints.
二次成型能將一組部件連接在一起，并同時保證機械完整性和對各種惡劣條件的抵抗能力，例如沖擊、磨損、化學產品、輻射、溫度和水分侵入等。
The overmolding joins together a set of parts while guaranteeing mechanical integrity and providing resistance to a variety of conditions such as shock, abrasion, chemical products, radiation, temperature, and moisture ingress.
//無連接器的復雜互連
Complex interconnects without connectors
對于復雜的連接，連接器并不是必需的，可以選擇更有趣的替代解決方案—二次成型的特殊外殼。其中端子通過壓接或焊接的方式與電纜連接，可以連續或半自動化生產。是具備連接器和電纜專業知識的制造商能夠提供的定制解決方案之一。
The use of connectors is not always required, even for complex links. Interesting alternative solutions can be implemented. Special housings with contacts crimped or soldered to an extruded cable, which is itself overmolded, in line in continuous or semi-automatic mode, are among the custom-designed solutions that connector and cable manufacturers who have integrated this expertise are able to offer.
