【Summary description】 Zhihang connector which is have base or no base, waterproof or not waterproof. The base can better ensure that the PCB and the connector are firmly connected together; no base is the form of socket, which requires less accuracy of PCB pin hole position, and can also save certain internal space, making the product more miniaturized. As for waterproof and not waterproof is based on the positioning of the product itself to determine.

As for waterproof and not waterproof is based on the positioning of the product itself to determine.

Connectors are widely used in military aviation, railway projects, industrial projects, aerospace projects, test instruments, ship systems, electric sightseeing vehicles; UPS; communication power supply; chargers, batteries and other products of the preferred high current connector. The connector is made of PBT material, which has good electronic and motor characteristics and can be widely used in industry.

The working principle of ZHIHANG connector is: printed circuit is usually made of printed circuit, printed components or a combination of both on insulating materials according to predetermined design. And on the insulating substrate to provide electrical connections between components of the conductive graphics, known as printed circuit. In this way, the printed circuit or printed circuit board is called printed circuit board, also known as printed circuit board or printed circuit board.

The connector industry in Chinese mainland is one of the few areas that are not affected by global economic recession. With the development of electronic equipment to higher transmission speed and miniaturization, connectors also follow this trend. Therefore, chip connector, optical fiber connector, wired broadband connector and micro gap connector which are suitable for various portable / wireless electronic devices are expected to become star products in the future.

The division of IP protection grade of ZHIHANG connector and the significance of grade number.

Smart air precision connector. IP is the international code used to identify the protection level. IP grade is composed of two numbers, the first number is dust-proof; the second number is waterproof. The larger the number, the better the protection is.

IP is the abbreviation of ingress protection. The IP grade is the protection level for the foreign matter invasion of electrical equipment enclosure.

The format of IP grade is ipxx, in which XX is two Arabic numerals. The first marking number represents the contact protection and foreign object protection level, and the second marking number represents the waterproof protection level. For specific protection level, please refer to the table below.

Dustproof grade

Definition of number protection degree

No protection, no special protection

1. Prevent objects larger than 50 mm from invading, prevent human body from accidentally touching the internal parts of lamps, and prevent objects with diameter greater than 50 mm from invading

2. Prevent objects larger than 12mm from invading and prevent fingers from touching the internal parts of lamps

3. Prevent objects larger than 2.5mm from invading completely, and prevent tools, wires or objects with diameter greater than 2.5mm from invading

4. Prevent the invasion of objects larger than 1.0 mm and prevent the invasion of mosquitoes, flies, insects or objects larger than 1.0 mm

5. Dust prevention can not completely prevent dust invasion, but the amount of dust intrusion will not affect the normal operation of lamps and lanterns

6. Dust prevention completely prevents dust invasion

7. To prevent the water from invading into the lamp's indefinite sinking water under certain water pressure, and to ensure the normal operation of lamps and lanterns

8 prevent the effects of sinking

Connector Selection Guide

1. Select the opening size, clamp size (the clamp size is based on the cable diameter) and the number of cores of the connector according to the needs;

2. Requirements for current and voltage;

3. Whether sheath is required.

4. Whether waterproof is needed;

5. Select chassis fixed, floating (docking) and PCB connector as required;

Material characteristics of insulator PPS in ZHIHANG connector

PPS is a new type of high performance thermoplastic resin, PPS is a kind of special engineering plastics with excellent comprehensive properties. PPS has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced physical and mechanical properties, excellent dimensional stability and excellent insulation.
