Before using the board-to-board connector, pay attention to check whether the connector is poorly connected or completely locked, so as to prevent problems such as simple failures when using the connector. So let's briefly understand the precautions of the board-to-board adapter and the key to simple negligent operation.
1. When using board-to-board connectors, pay attention not to plug in reverse or misalignment, when encountering poor plugging, remember not to forcibly plug and unplug to avoid damage to the internal pins of the connector.
2. The positive and negative lead distance of the board-to-board connector should be the same as the position of the PCB board solder hole, if the plug is forcibly pierced into the circuit board with a mismatched hole distance, the lead wire will be stressed, forming a short circuit of the board-to-board connector or the phenomenon of rising leakage current.
3. Because the board-to-board connector has more pins, and the pin wiring inside the interface will have certain wear every time it is pierced, it should be prevented from plugging and unplugging the connector too frequently, otherwise it will affect the service life of the board-to-board connector. In addition, when the board-to-board connector is pierced, pay attention to whether the pin is deformed to prevent violent puncture and then form a broken pin, or bent condition.
4. When tightening the screws at both ends of the board-to-board connector, you must pay attention not to have the screws on both sides firm, otherwise the screws on either side will be loose, which will simply cause the connector to tilt and form damage.
Simple negligent operation key:
1. Usually after the equipment is used at a certain time, please stop for a few minutes, wait for the operating elements of the board-to-board connector to meet the moment of heat dissipation, otherwise the load work for a long time, the metal terminals in the connector are easy to cause acceleration components to age, etc., also because the volume of the connector is small, if it can not accept its excessive working temperature, it will also form damage to the connector element.
2. Regarding the working environment of board-to-board connectors, it is generally because the internal terminals of the connector are mostly electroplated parts, so please note that the connector should not be applied to some too humid environments, otherwise the humidity will affect the insulation function of the connector. Therefore, when selecting connectors, we must pay attention to the humidity problem in the working environment, whether it will affect the use function of the board-to-board connector.
3. Because the plastic box of the board-to-board connection is broken in the injection molding stage, the usual process is to inject molten plastic into the metal tire film, and then quickly cool and mold. Therefore, after the connector is used for a period of time, some grease and other liquids will accumulate inside, and it may also be that the oil of some components in the circuit drips, so the use of the connector needs to be cleaned up from time to time to clean up the internal adsorption of water vapor or debris, if you do not accumulate too much, it will form some components in the circuit oil dripping into the circuit.
4. There are more end pins inside the board-to-board connector interface, so in the daily use of the connector, please pay attention to insist that these jacks must be kept clean, otherwise the board-to-board connector will accumulate and adsorb certain dust and debris after the long time of operation, so if it is not dealt with in time, it will not only affect the functional use of the connector, but also may cause some potential safety hazards.
5. In addition, the internal metal end pin components of the board-to-board connector are mostly composed of some electroplated parts, so generally in the storage package of the connector, the connector must be sealed, do not directly expose to the air contact, not then the connector will be affected by the humidity of the air, resulting in moisture oxidation inside the component. Moreover, the connector should generally not be placed for a long time when stored, to avoid some oxidative reaction, which will affect the quality of the product. Therefore, when the connector has not expired, use it as soon as possible.
6. In the process of plugging the board-to-board connector, it must ensure that the connector is firmly connected, and do not show some loose and unstable conditions, otherwise if there are loose and stable problems on the equipment, the connector connection should be ensured to be firm and reliable. In this way, once the connector is disconnected, it will cause some leakage conditions, so that the later stage will affect the operation of the entire circuit system of the equipment. Therefore, it is necessary to pay attention to the plug stability of the board-to-board connector.
