7/8 plug electrical connectors referred to as connectors, wiring terminals, is a subdivision of electronic components, mainly used for the connection between circuits. In industrial production, line connections can be said to be ubiquitous, so the use of connectors is of course very wide, used in various industries.
The correct selection and use of 7/8 plug electrical connectors is an important aspect of ensuring circuit reliability. The electrical parameters of the connector itself are the first issue to be considered when selecting the connector, and also include the safety parameters and mechanical parameters of the connector.
Rated voltage
Also known as the operating voltage, it mainly depends on the insulation material used in the 7/8 plug, and the size of the contact pair spacing. When some parts or devices are lower than their rated voltage, they cannot complete their intended functions.
Rated current
Also known as the operating current, the same as the rated voltage, below the rated current, the 7/8 plug can work normally. In the design process of the connector, the heat of the connector is designed to meet the requirements of the rated current, because when exposed to the current, due to the existence of conductor resistance and contact resistance, the contact pair will heat, when its heat exceeds a certain limit, it will destroy the insulation of the connector, forming a softening of the surface coating, resulting in failure. Therefore, 7/8 plug’s rated current is actually to limit the temperature rise inside the connector to not exceed the specified value of the design. Therefore, the multi-core connector should be reduced in use, and the more cores, the greater the reduction.
Contact resistance
Contact resistance refers to the resistance generated by two contact conductors in the contact part. The contact resistance of the 7/8 plug refers to the contact resistance, including the contact resistance and the contact conductor resistance.
Screening property
In modern electrical and electronic equipment, the increase in component density and related functions puts strict limits on electromagnetic interference.
Security parameter
Insulation resistance
Refers to the resistance value generated by applying voltage to the insulated part of the connector to generate leakage current on the active surface of the 7/8 plug’s insulated part. It is mainly affected by insulation materials, temperature, humidity, dirt and other factors.
Pressure resistance
It means that the critical voltage between the mutually insulated parts of the contact pair or between the insulated part and the ground can withstand higher than the rated voltage within a specified time, without damage. It is mainly affected by the geometry of contact spacing and climbing distance, insulation material, ambient temperature and humidity, and atmospheric pressure.
combustibility
The 7/8 plug is not only required to prevent fire, but also to self-destruct within a short time after fire.
Mechanical parameter
Single foot separation force and total separation force
The contact pressure in the 7/8 plug is an important indicator, which directly affects the size of the contact resistance and the amount of wear of the contact object.
Mechanical life
Connector life refers to the plug life, usually 500 to 1000 times.
Contact on number and pinhole properties
First of all, the number of contact pairs can be selected according to the requirements of the circuit, and the volume and total separation force of the connector should be taken into account.
Resistance to vibration, shock and collision
The main consideration is the electrical continuity of the connector under vibration, shock and collision under specified frequency and acceleration conditions.
Connection mode
The 7/8 plug is generally composed of a plug and socket, of which the plug is also called a free-end connector, and the socket is also called a fixed-end connector. Through 7/8 plug and separation of plugs and sockets, the connection and disconnection of circuits produce various ways of connecting plugs and sockets. For circular connectors, there are mainly threaded connections, bayonet connections and pin connections.
Terminal mode
The termination mode refers to the contact between the 7/8 plug and the wire or cable. Reasonable choice of termination mode and correct use of termination technology are also important aspects of the use and selection of connectors.
Waterproof 7/8 plug: A reliable guarantee for modern communications
With the development of modern communication field, people have higher and higher requirements for communication quality and reliability.
