  Power plug type and maintenance

  Power plug is generally divided into two core plug, three core plug and multi core plug, the first two are more common.

  Maintenance: do not use multiple large power electrical appliances in a socket Use temperature measuring instrument to measure the temperature of plug and power cord in use. If the temperature of socket or power line is too high, it should be stopped and replaced. In determining the state of the device shutdown, you can plug and test, check the plug into the socket should be in good contact, there is no sense of loosening, and not too hard to pull out.

  Cnlinko plug and socket type and maintenance

  The air plug seats are divided into screw type, bayonet type and marble type.

  Main points of maintenance: it is easy to screw loose or tight when inserting thread type plug seat. It can be marked at the junction of the plug when it is screwed to the proper position, and then the plug and play maintenance is based on the mark. Bayonet socket screw after clicking, without this sound, said corrugated spring problems, need to replace the same type corrugated spring. The utility model relates to a billiard type plug seat, which belongs to the direct pushing and pulling type connection mode, and has little separation force and is easy to loosen.

  The aviation plug pin seat and more intensive, the common faults are: when the broken line, plug bad contact; wire broken, insulation layer is worn; plug seat into the foreign body in a short circuit; insulator fragmentation or shell damage.

  Cnlinko RJ45 connector maintenance

  Maintenance point: a considerable portion of the network and phone faults are caused by damage to the crystal head. The repeated insertion will cause the deformation of the inside of the crystal head or the elasticity of the shrapnel, which will lead to poor contact. Most of the crystal head is plastic material, often plug and cause plastic buckle deformation and even fracture, resulting in shedding. Inspection should pay attention to the deformation of its metal shrapnel, and remember to observe the status of plastic buckle.
