Electronic connector design and development

Electronic connector is one of the electronic devices, which is widely applied in electronic equipments, space and aviation equipments, defense system, telecommunication equipment, also applied into computers and peripheral products, etc.

1. Target of connector design and development is to meet the requirement of function, structure and material properties.

(1) Conduction and connection function shall meet the requirement of signal transmission and power; the key properties include contact resistance, impedance, cross talk, contact stress, which can ensure DC and AC current transmission and reduce power loss; lower signal interference between capacitors and indicators;   

(2) Stresses, contact force and contact stress shall be considered when design connector structure to avoid material deformation, etc.

(3) Conductivity, fatigability, attrition resistance, electroplating shall be considered when choosing metal material; heat resistance, hygroscopicity, fluidity shall be considered when choosing plastic material.

2. Connector contact resistance

Connector quality depends on contact resistance; contact resistance can be divided in the two parts; contact material resistance and connection interface resistance.

3. Connector conduction and connection

Conduction performance is proportional to contact area, so contact area surface roughness will affect connection area directly.

Electric connector manufacturer--sunkye

Connector is an indispensable part of electronic device, when you observing electrical connection, you will find one or more connectors. Electric connector form and structure is ever-changing, different connector form depends on application, frequency, power and environment, etc. For example, connectors for lights and hardware driver are totally different from connector for rocket.

Centrical connector is the mini size connector, also with switch function; application is low frequency circuit, such as earphone, microphone, and power supply.

Strip connector, which is soldered on printed circuit board, reliable connection, easy to us, applied for connection of electric instruments.

Circular connector, screw coupling mechanism is very common, small size, high reliability, can meet the requirement of electronic device connection.

Rectangular connector, with locking component and design, main application is electronic devices, intelligent instruments and electronic control units, etc.

Waterproof sealing connector, which can be applied in water and other harsh environment.

RF coaxial connector is the small type screw coupling mechanism connector, small, light and easy to use, suitable for wireless electronic devices, high frequency circuit connection in electronic instruments, etc. Working frequency is about 500MHz.
