What wires are suitable for wiring on bread board?

Jane Medium ： For the type of wire used in bread board wiring 、 Color 、 Length and durability are discussed . Perhaps there is no perfect choice , It depends on the situation . For students , Because the circuit content needs to be replaced frequently , Therefore, the DuPont line with double male heads is more suitable for completing the experiment . For professional test circuits , It is more professional to use a single wire to complete the circuit construction .

key word ： Breadboard , Lead wire , DuPont line

 

§00 front    said

As a platform for electronic circuit experiment Breadboard With its simplicity 、 Flexibility has been widely used for a long time . As the skeleton of the circuit , The lead on the bread board has certain requirements . Some wires are very suitable for connecting wires on bread boards , But there are still some unsuitable . In Bowen The Best Wire for Breadboarding Some suggestions about bread board leads for electronic beginners are given in .

   Connect the circuit on the bread board , And we all saw it , It's the messy connection of seven connections and eight connections on the bread board . There are many skills and methods about how to better wire the bread board , But today we will only talk about one of the simplest factors , That's it ： Have you chosen the right wire ？

 

§01 single Strand conductor

---

   also The most common lead used on the bread board is a single strand wire . They are usually divided into many colors , Sell in bundles or reels , It has different lengths . The recommended wire diameter for bread board is 0.64mm,（22awg）.

1.1 advantage

• The price is low - A bundle 25 A foot long single strand wire is usually only a few dollars ;
• Various colors - Since there are many colors of wires available , There is no need to make excuses for not using a specific color for the power cord . Using different colors to distinguish different lines can make the circuit on the bread board more clear ;
• Suitable length - This bundle of wires can be cut to a suitable length for wiring according to requirements when in use ;

1.2 shortcoming

• Operation trouble - Because the single strand conductor is very long , Therefore, it is necessary to cut and peel when using , Therefore, it will take some time to build the circuit on the bread board ;
• It's easy to break - A single strand of wire is easy to break after many folds , Especially when the metal wire breaks in the socket on the bread board , It takes a lot of effort to take out the wire left in the hole of the bread board .

 

§02 pre Wire cutting

---

   One Some bread boards are sold with pre cut and bent wires , Sometimes the wire ends are tinned to reduce the contact resistance . These pre cut wires have different lengths and colors , It is usually divided into different colors according to the length . These mixed pre cut wires come from different vendors , But the specifications and types are basically the same .

2.1 advantage

• Various lengths - It usually has 8 ~ 9 Pre cut wires of different lengths ;
• Tinned thread ends - The lead ends are usually plated with tin , This is more durable than non tinned leads ;
• storage box - These wire calls will be equipped with appropriate storage boxes , Convenient for storage and reuse ;
• Suitable for cutting - Most of the wire diameters of these conductors are 22/23 awg, Suitable for plugging on bread board , It can also be cut to a suitable length for application .

2.2 shortcoming

• Color coding - Since the color of pre cut wires is usually used to represent different lengths , This is not suitable to represent the nature of the lead on the bread board ;
• cost - Such pre cut wires are usually more expensive than bundled single strand wires ;
• fragile - It also has the problem that a single strand wire is easy to break , After all, it is also a single strand wire ;

 

§03 The color Color DuPont line

---

   The color Color DuPont line is very popular for breadboard wiring , Its two ends have special thread ends, which are suitable for pinching and plugging on the bread board with bare hands . It is far more durable than other kinds of wires .

Be careful ： DuPont line is divided into ： Double male lead 、 Double female lead 、 One male and one female lead . Use double male leads on the edge of the bread .

3.1 advantage

• durable - Compared with single strand wire , The thread end of DuPont line is not easy to break in the hole of bread board ;
• flexible - DuPont lines are often multi strand metal wires , It's softer than a single strand of wire . So as a cable , It is more flexible and durable ;
• color - DuPont lines usually have many colors , Therefore, it can represent different leads in the circuit ;

3.2 shortcoming

• length - In general, DuPont lines have few kinds of lengths , There are only one or two , So when wiring on the bread board, it usually flies , Cause the wiring to appear messy ;
• cost - Among all leads, DuPont wire is more expensive , In order to save money, you may not prepare too many flying lines ;

 

§04 avoid Free of use

---

   stay The following wires should be avoided on the bread board .

▲ chart 4.1 Wires avoided on bread board

• Multi strand wire ： This kind of metal wire is composed of many strands . As a wire, this has advantages ： The wire is soft , Bending resistance , AC signal impedance is small ; But the thread is not easy to plug and unplug on the bread board . The falling thin line is also easy to remain in the hole of the bread board , Or cause a short circuit in the circuit ;
• Enameled wire ： This kind is only used in inductance 、 It is not easy to remove the external insulating paint from the wire of the electromagnet , Inconvenient to use ;
• Fine thread ： Best use 22awg Specification single strand conductor , Too thin wires are not easy to peel ; It's easy to break . Easy to fall off the bread board .

For students , Because the circuit content needs to be replaced frequently , Therefore, the DuPont line with double male heads is more suitable for completing the experiment .
