Background

The traditional connector wiring mode usually adopts soldering tin or crimping mode, and the soldering tin personnel need through professional training and technical ability discrepancy, and the soldering tin process often has rosin joint, false solder, solder joint quality scheduling problem not good. If crimping is used, a special crimping tool is required, and the corresponding tool needs to be replaced when each conductor or wire gauge is different. Therefore, the requirement on the professional degree of the personnel on the terminal use site is extremely high. The connector generates electromagnetic wave during the process of transmitting large current, and the electromagnetic wave is easy to interfere with the peripheral signal connector.

Most of the applications in the market are power connectors or signal connectors which are respectively installed on equipment, although the interference of the power end to the signal can be avoided, because at least two connectors are used for transmitting the signal and the power, more space is needed for placing the connectors, the cost is increased more, and the follow-up maintenance and replacement are more complicated. In a conventional power connector, a male terminal is not completely covered by an insulator or a certain gap must be provided between the insulator and the terminal, so that the male terminal is easily touched by mistake to cause an electric shock accident when the male terminal is electrified.

The current connectors also have the following problems:

1. when a larger wire is soldered, the soldering time is long, and the problems of insufficient soldering, overlarge soldering points, unstable quality and the like easily exist in the soldering process;

2. the connection of the crimping lead needs a special tool and needs professional personnel for installation;

3. after the connector is connected with a lead, under the influence of the installed environment, under a specific environment (such as high temperature, high humidity or high and low temperature), the connector thread is loosened due to the stress of materials and the influence of mechanical force between the connector and the lead, the lead cannot be effectively clamped and fixed by the connector, and the lead and the terminal connection part of the connector are easily impacted by large force, so that the electrical performance of the connector is unreliable;

4. when transmitting large current, it will generate electromagnetic wave, which is easy to interfere the peripheral signal end;

5. during large current transmission, the male terminal of the connector is easily touched by a user to cause potential safety hazards of electric shock.
