Detailed description of the invention
During power construction, the laying of cable is particularly important, and most cable is all provided underground, this just has strict demand to cable connector, because on the one hand provided underground is difficult to observe maintenance cable connector, on the other hand underground environment is poor, topmost problem is exactly moist, and moisture can be stopped by equipment such as some boxes easily unlike solid matter, as long as there being gap moisture just can pierce, therefore bringing the biggest puzzlement to cable connector, cable connector is as easy as rolling off a log after making moist causes power supply impact to whole circuit, and serious also can set off an explosion.The mode processing cable connector at present in construction typically uses the form of armored cassette, also has the mode using winding armoring tape then two ends fixing, but connection equipment all and has gap between cable, be very easy to cause moisture to enter.In order to solve this problem; the present invention uses and the mode of cable core one; being fetched by two parallel grooves and projection card prevents moisture from invading; when employing one groove and projection clamping are found through experiments; moisture still can invade along gap; when using two grooves and projection clamping; owing to adjacent grooves forms continuous print concaveconvex structure; therefore the effect stopping moisture can well be played; and when using three groove structures; on the one hand adding the size of cable core protective cover, on the other hand processing and installation are also inconvenient.Concrete structure is as follows:
Such as figure
