Detailed Description

Referring to fig. 1 to 4, the utility model discloses a bus duct grafting electronic box, including electronic box casing 1 and with 1 articulated case lid 2 of electronic box casing, circuit breaker 3, a plurality of copper bar clamp 4, be equipped with supporting seat 5 that interface and insulating material made in the electronic box casing 1, the copper bar clamp 4 is fixed in on the supporting seat 5, on the supporting seat 5 was fixed in 1 lateral wall of electronic box casing through the fastener and the exposed outside electronic box casing 1 of tip through the interface of copper bar clamp 4, the fastener was the screw, and supporting seat 5's specific mounting structure lies in: the supporting seat 5 is square, the interface is square, the supporting seat 5 covers the interface, and the connecting plate 6 is arranged on the outer side wall of the supporting seat 5, and the connecting plate 6 is fixed with the electric box shell 1 through screws. Be equipped with a plurality of square mounting grooves 7 in the supporting seat 5, the tank bottom of mounting groove 7 is equipped with the through-hole, be equipped with the screw that corresponds with the through-hole on the bending plate, the screw passes through-hole and screw cooperation, and the copper terminal cover of power cord is connected and switches on through screw and copper bar clamp 4 on the screw. Circuit breaker 3 installs in electronic box casing 1 through the backup pad, plays power protection effect through circuit breaker 3, and the electric current is too big and circuit breaker 3 can break circuit to play the effect of protection circuit, thus circuit breaker 3 is specifically not detailed for outsourcing, and the copper bar presss from both sides 4 and is connected with circuit breaker 3 through the wire, copper bar clamp 4 includes T clamp headstock, two conducting strips 8 and two elastic clamping piece 9, and this T clamp headstock includes adjusting pad 10, the buckling plate 11 of two L shapes, conducting strip 8 is located between corresponding buckling plate 11 and elastic clamping piece 9 and is connected for half clamp through copper rivet 12, and partly connection process of having simplified follow-up bolt of preassembleing in advance, and concrete structure lies in: 8 tip of conducting strip pastes on buckling plate 11, and elasticity clamping piece 9 hugs closely on conducting strip 8, and conducting strip 8, buckling plate 11 are connected as an organic wholely with elasticity clamping piece 9 through copper rivet 12, and above-mentioned structure not only plays fixed purpose, and conducting strip 8 passes through
