It’s widely used in analog signal transmission. The simple structure design is from the long history. Until today, it’s still used in
recording devices, audio players, amplifiers, active speakers, and so on.
RCA plug's structural section is a standard coaxial design although there is no standard characteristic impedance but
sometimes it is used for other RF terminal adapter interface, and
to delivery composite video signals (the appearance is orange), or S/PDIF format digital audio signal.
For the interface of RCA terminals, the long and thin conductor is the positive pole. The inner diameter is about 3.175mm (1/8”).
The outer larger body or the shell is the negative pole. The inner diameter is about 8.25mm (1/3”).
There is insulator between the positive pole and negative pole to isolate the insulation material.
In the analog signal transmission, the left channel’s appearance is red color and the right channel’s appearance is white or black color.
廣泛應用於類比訊號傳輸，發展歷史長久及結構簡單的設計，迄今仍被應用於
錄音裝置、音頻播放器、擴大機及主動式揚聲器等設備。
RCA端子在斷面結構上是屬於相當標準的同軸設計，僅管沒有標準的特性阻抗，
但有時仍被採用作為其他RF端子的轉接介面，以及被應用於
複合視訊訊號傳遞(外觀為黃色)或S/PDIF格式的數位音頻訊號(外觀為橘色)傳遞。
RCA端子在介面部分，中心細而長的導體為正極，外徑約為3.175mm(1/8")，
外部較大的本體或外殼為負極，內徑約為8.25mm(1/3")，
兩者之間以絕緣材質隔離，在類比訊號傳遞時，左聲道外觀為紅色，右聲道外觀為白色或黑色。
Notice for customized products:
1. The contact pins has divided into 4 types:
Sold type (RP-1281), One-line-cutting type (RP-1273), Cross-cutting type(RP-233), and Hollow type(RP-4041).
2. The way of connecting contact pin and cable conductors has divided into 2 ways:
Solder type (A type) and Screw type(B type).
Generally RCA has these 2 types but sometimes it will combine Solider and Screw type together (AB type).
3. The common conductors’ materials are Brass, Tellurium Copper, Copper, and Pure Sliver.
The insulters’ materials are POM, ABS, and PTFE.
To choose the right material, it will depend on the electrical characteristics, mechanical characteristics, and cost.
客製注意事項：
1.中心針可分為實心(RP-1281)、一字剖溝(RP-1273)、十字剖溝(RP-233)及空心(RP-4041)類型，請詳圖面。
2.RCA端子在中心針聯接線纜導體的處理上分為焊錫焊接(A type)及螺絲鎖固(B type)，
本類別的產品大致皆可客製上述兩種，甚者為混合共用類型(AB type)。
3.常見可應用的導體材質有黃銅、碲銅、紅銅及純銀；
絕緣材料有POM、ABS及PTFE，材質的應用取決於電氣特性、機械特性及成本需求等。

In order to fix the wire by crimping, it will need to use tools to clamp the clip to fix the wire and connector.
In the classification, it’s distinguished by the number of ditches on the interface of the body.
The number of ditches is depends on the mechanical characteristics and electrical characteristics.
When it matches with female plug, the less ditches will cause higher insertion force;
the more ditches will cause lower contact impedance.
以壓接方式固定線材，需透過手工具夾持線夾於線材上，以固定線材與連接器。
在分類上以本體介面端剖溝的數量區分；
大致上剖溝的多寡在機械特性上，剖溝越少，與母座配合時的插拔力較高；
在電氣特性上，剖溝越多，與母座配合時的接觸阻抗較低。
There has an inner copper tube with thread in it.
The external body has proper ditches, it will tight up to the copper tube via shell to reach the locking function.
Please refer to Clamp classification.
除了以線夾夾持線材外，還有以銅管內徑車削螺紋，外部適當剖溝後，
藉由外殼鎖故後緊迫銅管，達到夾持固定的功能，請參考Clamp分類。
Notice for customized products:
1. Clamps are available in sizes 6mm and 8mm for cable outer diameters.
客製注意事項：
1.線夾針對線纜外徑分有6mm及8mm規格
In order to fix the wire with screws,
it will need to use screwdriver to fix the wire with body or shells of connector.
The screw is removable so it can be repaired or reused.
In the classification, it’s distinguished by the direction of locking the housing and body.
1. Locking from the front housing. (It will be locked from the interface side.)
2. Locking from the back housing. (It will be locked from the terminal.)
3. Stationary housing.
需透過螺絲起子將本體或外殼以螺絲與線材鎖固，由於螺絲可拆卸故具有可維修或再使用的功能。
以外殼與本體鎖固的方向分類，
區分為前殼(外殼自介面端鎖入)以及後殼(外殼自接線端鎖入)，以及固定式外殼。
Notice for customized products:
1. Screw head types are divided into 4 types:
Slotted screw, Philips screw, Hex Socket screw, and Torx (Star) screw.
客製注意事項：
1.螺絲頭種類可區分為一字、十字、內六角及星型螺絲。
