4 Ways To Shield Over-molded Connectors For Custom Cable Assembly

Shield Over-molded connectors play a significant role in aiding in the transmission of data. Also, cable assemblies are sensitive to electromagnetic and RFI.

The sensitivity of the cable assemblies and over-molded connectors explains that it is necessary to protect the connector’s shield at all times else; it poses a problem when in use.

A significant disadvantage that cable connectors and cable assemblies encounter when they are not adequately protected is that they produce a low quality of signals, and in worse situations, the complete loss of data and information.

There are four different ways to shield over-molded connectors for custom cable assembly properly.

1.Foil Shielding

It is the most suitable way of shielding the over-molded connectors for custom cable assembly. It provides 100% coverage for the over-molded connectors, and they are also easy to carry about.

If you require a shielding type that withstands high frequencies without posing any danger or damage, your best bet is foil shielding. Also, the foil shielding of the over-molded connector is suitable to control the effect of radio-frequency interference.

The foil shielding comprises a thin layer of copper and aluminum accompanied by polyester that increases its strength.

Furthermore, foil shielding is easy to terminate in situations where you no longer need it.

Another reason the foil shielding of an over-molded connector for cable assembly is best is that it is cost-effective. Although, the foil shielding method of the over-molded connector of custom cable assembly possesses its drawbacks.

The major drawback of foil shielding is that it may pose a problem for you to work with due to the physical outlook of the shield. The thinness of the foil shielding makes it sometimes difficult to use.

2.Shield Over molded ConnectorsBraided Shielding

Unlike the foil shielding that provided 100% coverage, the braided shielding offers about 70-90% coverage.

Braided shielding is considered one of the oldest methods of shielding over-molded connectors, and it is usually at its optimum at low frequencies.

The strength of the braided shielding of the over-molded connector is second to none, and it is very flexible as well, making it easy to use. If your custom cable assembly requires a medium-frequency application, then you must favor braided shielding.

Interestingly, braided shielding is one of the most secure ways of protecting your over-molded connectors from the harsh effects of electromagnetic interference.

The physical properties of braided shielding include a woven mesh of copper wire, and it is usually a thinned thinner hat that appears twisted around the over-molded connectors.

The braided shield is disadvantageous in that it makes the over-molded connector resistant to ground factors. To ensure that the braided shield of the over-molded connector is firm and secure, it is best to secure the braids to be resistant to other factors tightly.

Not all organizations can afford the braided shielding of over-molded connectors of the custom cable assembly. No doubt, the braided shielding possesses a bulky outlook, which is beneficial because it protects the over-molded connectors.

3.Shield Over molded ConnectorsA Fusion of Foil and Braid

This type of shielding possesses the features of both foil shielding and braided shielding. It combines the characteristics of both types to enhance its functionality.

Just like the foil shielding method for custom cable assemblies’ over-molded connectors, this type of shielding provides 100% coverage. The mechanical strength of the fusion of foil and braid shielding is second to none.

Ideally, this type of shielding is not selective, and it works for two kinds of frequencies. The foil shielded method of over-molded connectors of the custom cable assembly is suitable for high frequencies, while the braided shield is ideal for medium-frequency.

But, the fusion of foil and braided shield is suitable for both the low and high frequencies. A unique aspect of this type of shielded over-molded connector of the custom cable assembly is that it tries to outdo any interference of sort completely.

The foil shielded way to shield over-molded connector works to eliminate the presence of radio-frequency interference. In contrast, the braided shield is suitable to overcome the obstacles that electromagnetic interference may pose.

The fusion of foil and braided shield is suitable for overcoming radio frequency interference and electromagnetic interference obstacles. Thus, this method of shielding the over-molded connector of the custom cable assembly is very efficient for eliminating noise.

An outstanding advantage of this shielding method is that it is based on each other’s gifts and overcomes its disadvantages.

The fusion of foil and braid shielding helps strengthen each other’s characteristics rather than relying on their weaknesses. When both methods of shielding over-molded connectors of custom cable assembly are fused, they no longer shield individually, and instead, they work together as one.

4.Shield Over molded ConnectorsSpiral Shielding

It is another way to shield over-molded connectors of the custom cable assembly. The braided shielding is known to be flexible. But, its flexibility cannot be compared to the spiral shielding method.

If you hope to settle for a shielding method that is very compatible with low frequencies, the best shielding type for you is spiral shielding.

Terminating spiral shielding is very easy when compared to braided shielding. The spiral shielding method of shielding over-molded connectors of custom cable assembly does not guarantee 100% material coverage, but they can make up for 95-98% coverage.

The spiral shielding method of shielding over-molded connector is very similar to the braided shielding. The significant difference between both types of shielding is that braid in the woven pattern is used for shielding.

For spiral shielding, it uses straps of wires that coiled around the conductor in a spiral pattern. This type of shielding is best for audio equipment such as microphones and audio cables.

The application of the spiral shielded method of shielding over-molded connectors in custom cable assembly is not limited to audio equipment. It is also used for retractable cord cables that use long-life.
