    How to use male plug connector? DIY 2022


    Banana plugs

    male plug connector

    Some inexpensive audio devices have terminals in the form of pressure clamps, into which the stripped cable ends insert directly. This is sufficient for ordinary applications and there is not much difference in signal quality. However, male plug connector is much more practical, especially in places that are difficult to access.

    How do I assemble a banana plug?

    To fix the stripped cable ends in the male plug connector, remove the connector's protective cap and loosen the two grub screws with a small screwdriver.

    The well-twisted strands of the free end of the cable can now insert into the metal pin. Tighten the screws and attach the protective cap - the banana plug is ready to use.

    What does male or female mean in relation to lab connectors?

    A distinction is made between the actual male plug connector, which plugs into the appropriate laboratory socket (female). Incidentally, the two designations also use for other types of plugs.

    Laboratory plugs not only fit into laboratory sockets, but also into sockets. This is especially dangerous in households with children. Only plugs with solid insulation should use in connection with mains current.

    For this reason, the use of banana plugs is controversial in Europe, but they allow. Only the sale of stereo systems with banana sockets prohibits.

    Can you plug banana plugs into an outlet?

    Most devices on the market comply by putting a safety pin on the sockets, making it difficult to use male plug connector. However, this pin removes at your own risk so that banana plugs are easy to use.

    The simplest conceivable form of banana plugs uses for simple plug-in connections, for example between electronic measuring devices or stereo systems and loudspeakers.

    There are also variants in which the plugs have either a transverse hole or a coupling next to the cable. These use to connect multiple plugs to the same source.

    Disadvantages of banana plugs

    The main disadvantage of the male plug connector is the lack of reverse polarity protection. If connector colors are the only distinguishing feature, then there is a high probability of confusing the plus and minus socket. This usually regulates by red (plus) and black (minus) plugs.

    Another disadvantage results from the different designs. As mentioned above, the classic banana plug has only one leaf spring, which means that a large part of the plug has direct contact with the socket.

    Bunch plugs usually only have contact with a small area, which is at the expense of the current flow. What is irrelevant for power transmission can lead to errors in fine measurements.

    Where are banana plugs used?

    The male plug connector uses more often than we actually realize. It can be found in every laboratory worldwide, is indispensable in electronic measuring devices and enables fast connections to the loudspeaker. But we even encounter them at the doctor's or in the hospital:

     After the contact surface has been glued to the chest, the doctor “wires” us to the EEG device using banana plugs.

    Unfortunately, the Hirschmann Company no longer has any of the groundbreaking invention. After various sales and demolitions, "Hirschmann banana plugs" are still manufactured under the brand name today - but they come from a different company.

    What do you prefer when shopping?

    Is it okay with you if the smartphone display is a little scratched or there are already a few signs of wear on the back? Or does an item really have to be completely new when it purchases?

    Male plug connector, which – depending on their diameter – are also referred to as four millimeter spring plugs (4 mm spring plugs) and are also known as lamellar plugs, serve as plug connections for cables.

    A leaf spring element attaches to the pin of the plug, which ensures that the plug is firmly seated and at the same time enables tool-free use. The spring gave its name to the banana plug due to its curved shape.

    Use of male plug connector: the cables clamp on the left and connected to the plug on the right. So the cables are easy to change quickly.

    Male plug connector features

    The male plug connector was originally developed as a plug connection for use in electrical laboratories and is mainly use with low voltage - up to around 16 amps. It also uses in private households, for example for the wiring of music systems:

     The cables between the loudspeakers and the amplifier are often attached with banana plugs.

    Four millimeter spring connectors are part of the standard equipment in electrical laboratories and use there in the test setup. They replace the previously use screw connections and spring clamps.

    Pros and cons of banana plugs:

    advantages Disadvantages
     Good signal transmission

    Strong hold

    Simple and multiple plugging, unplugging and replugging is possible without any problems

    No thread required for use, 4 mm drill hole is sufficient

    · No shielding against interference

    Male plug connector with a cross hole are also particularly practical: this allows additional cross connections to plug in.

    A variant of the banana plug is the so-call tuft plug: This usually provides with six spring wires and also has a higher resistance.

    Bunch plug with transverse hole

    If you want to make cables for your home cinema system or hi-fi system yourself, you can simply proceed as follows:

    1. Using wire strippers remove a few millimeters of insulation from each phase of the cable (also call strands).
    2. To bundle the individual wires of the phases, you can twist them between two fingertips and connect them together. Your fingers should be completely clean.
    3. Next, twist the Male plug connector

    2nd tip: make your own audio cable with banana plugs

    • Use a small screwdriver to loosen the retaining screw(s). A phase tester (“voltage tester”), for example, is suitable for this.
    • Then push the stripped wires of the stranded wire into the connector.
    • Finally, retighten the retaining screw(s) to secure the cable in the connector.

    Tip: Always use the same color of male plug connector for the two ends of the same strand to make subsequent wiring easier.
