Description

Portable motor terminal block

Technical field

The utility model relates to the manufacturing field of motor, is applicable to that seat No. H315～355 threephase asynchronous machines lead-in wire is connected with power line.

Background technology

Our company produces the existing history for many years of threephase asynchronous of all size model, and motor assembling manufacturing technology is gone on along in prostatitis of the same trade, and motor performance is good, firmly gets user's trust.But the motor wiring part of seat No. H315～355 threephase asynchronouses is because wiring space is limited, and the lead-in wire external diameter is thicker, and vacuum paint dipping rear motor lead-in wire is difficult to bending.The traditional wired plate, adopt binding post to separate with terminal block, connect binding post earlier after, binding post passes from the wiring plate hole again, and then terminal block is fixed on the motor casing base, wiring and clamp operation are all very difficult in this process, operating efficiency are reduced, simultaneously, after pressing, causes by terminal block line ball bolt or motor down-lead and chassis sidewall appearance overlap joint on the plate internal wiring terminal easily, cause electrical machine insulation intensity to reduce, and then cause motor ground connection, the generation of turn-to-turn fault.By invention portable motor terminal block, solved this difficult problem:

1) traditional wired intralamellar part wiring, sheet-pile separate, and material usage is big, and being connected of the fixing and circumscripted power line of binding post need be with copper nut and the plain cushion of 12 M16.

2) traditional wired intralamellar part wiring, pressing plate then, motor down-lead is juxtaposition straggly behind pressing plate, particularly goes out the motor of 12 lead-out wires, causes the motor turn-to-turn easily, hidden danger such as ground connection.

3) owing to after the traditional wired plate needs binding post to connect, be fixed on the terminal block by passing in the wiring plate hole respectively, be action need, after every binding post carefully connects the wire, need leave certain threading space.Cause length that motor down-lead stays to increase, fixedly bring difficulty, production efficiency is reduced to terminal block.

At above weak point, we have invented portable motor terminal block, have reduced material cost, have improved production efficiency and motor quality, have solved problem.

The utility model content

For solve the deficiency that the conventional motors terminal block exists in producing use, the utility model patent provides a kind of delicate structure, easy for installation, saves the portable motor terminal block of cost.

The technical scheme that its technical problem that solves the utility model adopts is:

Portable motor terminal block profile is circular, three is long, three short six roots of sensation binding post, wherein U1, V1, W1 is the shorting stub terminal, W2, U2, V2 is long binding post, three braces, every binding post is joined M10 * 25 brass bolts, copper plain cushion, spring pad, M16 * 20 brass bolts, copper plain cushion, each one of spring pad, be used to connect motor lead-out wire and power line, on the motor lead-out wire behind the cable end, cable end is pressed abd fixed on the binding post side with the bolt of M10 * 25, is fixed and clamped power line on the binding post top with M16 * 20 brass bolts.

Portable motor terminal block, it is characterized in that: binding post waters and casts from the terminal block base, the side is processed with the connection bolt hole, wire hole is reserved in the binding post outside during casting of terminal block base, motor down-lead is drawn by binding post outside wire hole, utilize connection bolt to be connected to the binding post side, processing inner bolt hole in binding post top utilizes connection bolt that power line is connected to the binding post top.

The beneficial effects of the utility model are:

1) motor down-lead is directly drawn from the wire hole of terminal block both sides, is connected to the binding post side, has reduced the difficulty of wiring, has improved the operating efficiency of wiring.

2) motor down-lead juxtaposition behind pressing plate has been avoided in externally wiring of portable motor terminal block, has eliminated the motor turn-to-turn, hidden danger such as ground connection.

3) the binding post direct pouring of terminal block becomes one with terminal block on the terminal block base, need not resemble the traditional wired plate and fix with nut, has reduced copper consumption, has saved cost.
