First, RCA interface connector

① Introduction

RCA is an acronym for Radio Corporation of America, as RCA connectors were invented by this company.

RCA connector is by far the most common type of audio / video terminals in the mainland is called Lotus plug in Taiwan, said plum connector, also known as AV terminal, also known as AV interface, almost all of the TV, video player products Have this interface. RCA is an interface design that can be used both for audio and for general video signals.

② material

Center PIN material: nickel-plated brass, solid PIN (car);

Brass material: 0.4mm thick brass nickel plated.

③ types

RCA Type: A, tubular B, lotus petal C, all-metal assembly (plastic assembly)

Second, HOUSING

Definition: HOUSING is the plastic body of the connector before it is added to the terminal. It can also be said that HOUSING is the terminal house, and HOUSING becomes the connector head after penetrating the terminal. HOUSING a wide range, but the vast majority are used in the internal connection of the machine.

 Third, D-sub

① definition

Commonly known as VGA (Video Graphics Adapter) interface. May be because the vertical looks like a capital letter D, so called D-Sub. D-sub is the abbreviation of D-subminiature.

PINs: 9,15,25,37,50

② plastic core material: blue, white or black, 70% PBT +30% glass fiber terminal material: brass red PIN, ?1.0mm, thickness 0.2 ~ 0.25mm.

Terminal Plating: A: Gold Flash (3μ, 5μ, 15μ, 30μ) B: Half gold (before plating, after plating)

Steel shell material: Cutting steel, nickel or tin, the thickness of 0.4 ~ 0.5mm. Male RBI aims to enhance the contact of steel. D-SUB has riveted hexagonal and riveted cylindrical two before

③ name means that? Connector manufacturer

For example: DB25, the first letter D is D-sub, the second letter B is the size of the description interface - corresponds to the following numbers (number of stitches) (A = 15 stitches, B = 25 stitches, C = 37 Needle, D = 50 stitches, E = 9 stitches). Each interface is sub-male (plug) and female (socket)

Fourth, BNC interface connector

The British Naval Connector (probably the earliest British navy to use this connector) or Bayonet Neill Conselman (Designer: Paul Neill, Carl Concelman, & Octavio M. Salati) is a very common type of RF terminated coaxial cable termination Device. BNC interface is often said that the thin coaxial cable interface.

BNC for coaxial

Wire type (MINI COAXIAL RG174)

Assembly (RG58 RG59)

Material Classification: Can be divided into brass, zinc alloy, stainless steel

Fifth, DC PLUG and MIC PLUG

DC PLUG low voltage power plug, nickel-plated (2.5mm 3.5mm 4.0mm 5.5mm)

MIC PLUG microphone plug, common nickel-plated and gold-plated (6.5mm)

Six, IDC SOCKET

PIN number: 10,20,26,34,40,50,64 These connectors except connectors are plastic structure, the complete three-piece:

A, the body, that is, the connector, there are KEY and no KEY (nose and no nose) (KEY intended for the key, in this sector, the intention of foolproof device.)

B, pressure bar

C, SR (flip cover)
