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.

//无连接器连接

Connecting without a connector

对于印刷电路板组件(PCBA)上的连接应用，通常会选用标准连接器，但根据尺寸和客户的具体要求，提供定制的互连解决方案是很有必要的。

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

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.

在该设计方案中，设计者可以根据应用所需的电流来定义端子的尺寸。不同厚度和镀层的合格Pressfit产品可以满足客户的规格要求。然后将带有Pressfit端子的PCBA组装到塑料外壳中。这种解决方案降低了实现连接器的成本，并提供了一个完美的集成单元。

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

二次成型连接方案也可被用于满足客户的需求。与客户的协同工程阶段在产品定义中起着至关重要的作用:在流变学应用软件的帮助下优化零件的几何形状，并根据各种条件要求选择材料(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.

二次成型能将一组部件连接在一起，并同时保证机械完整性和对各种恶劣条件的抵抗能力，例如冲击、磨损、化学产品、辐射、温度和水分侵入等。

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.

//无连接器的复杂互连

Complex interconnects without connectors

对于复杂的连接，连接器并不是必需的，可以选择更有趣的替代解决方案—二次成型的特殊外壳。其中端子通过压接或焊接的方式与电缆连接，可以连续或半自动化生产。是具备连接器和电缆专业知识的制造商能够提供的定制解决方案之一。

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.
