Specific embodiment
The utility model embodiment is described further referring to figs. 1 to Fig. 3.
The utility model discloses a kind of mine cable terminal box, including terminal block housings 1 and cap 2, the terminal boxes
Shell 1 has a wire connection cavity 10, and ceramic connecting terminal 3 is equipped in the wire connection cavity 10, and the ceramics connecting terminal 3 passes through fixation
Bolt 30 is fixed on 10 bottom of wire connection cavity, and the ceramics connecting terminal 3 is equipped with multiple binding posts 4, and the binding post 4 includes setting
The connection bolt 40 on ceramic connecting terminal 3 is set, lower fastening nut 41, lower clamping piece are successively arranged on the connection bolt 40
42, the outside of upper clip 43, elastic force gasket 44 and upper fastening nut 45, the terminal block housings 1 is equipped at least two inlet wire columns
11, the inlet wire column 11 is interior to be equipped with the mounting hole 12 being connected with wire connection cavity 10, twists on the mounting hole 12 and draws equipped with cable
Enter device 5, gasket seal 13 is equipped between the cable entry 5 and mounting hole 12.The terminal block housings 1 are polygon
Or it is round.The terminal block housings 1 are integrated drawing and forming setting.
In actual operation, extraneous cable is guided in wire connection cavity 10 by cable entry 5, it then will be to be connected
Two cables are wrapped between the lower clamping piece 42 on connection bolt 40 and upper clip 43, then will by screwing upper fastening nut 45
Two cables are firmly fastened between lower clamping piece 42 and upper clip 43 and fix, and can power on use later.
Wherein elastic force gasket 44 can play the function that stabilization falls off when upper fastening nut 45 is tightened, and improve cable
The stability of connection, while good insulating effect can be played using the connecting terminal of ceramic material, there is extremely strong explosion-proof effect
Fruit, and gasket seal 13 is equipped between cable entry 5 and mounting hole 12 can play the effect of waterproof sealing.
The terminal block housings 1 are welded in the wire connection cavity 10 far from convex block 14 is additionally provided on one end lateral wall of cap 2
