What the technical solution of the utility model was realized in：A kind of square connector cover on motor, including lid Body, it is characterised in that：The lid includes direction cover plate and the side plate that is at right angles connected with direction cover plate, the direction cover plate with The junction of side plate is provided with reinforcement projection, and reinforcement projection includes the first curved portions and the second curved portions being connected with each other；Institute The inwall for stating side plate is provided with holding tank, and sealing ring is provided with the holding tank, and described sealing ring includes sealing ring body, should The outer wall of sealing ring body is in outwardly arc shape, and the inwall of the sealing ring body is in the arcwall face of indent, the sealing ring The edge of inner ring is extended with first annular raised and the second annular protrusion to axial two ends, and the edge of sealing ring outer ring is to axially two End is extended with the 3rd annular protrusion and fourth annular is raised, and it is recessed that the first annular projection forms upper annular with the 3rd annular protrusion Groove, second annular protrusion and fourth annular convex to form lower annular groove, are spaced on the end face of described the 3rd annular protrusion It is provided with buffer stopper, the raised end face of fourth annular and is arranged at intervals with lower buffer stopper；The groove width of the upper annular groove by Bottom land is become larger toward notch, and the groove width of the lower annular groove is become larger from bottom land toward notch.

By using above-mentioned technical proposal, the square terminal box is fixedly connected with lid by screw-nut, and passes through three The junction of layer sealing ring square shaped terminal box and lid, which is realized, to be sealed, it is ensured that dustproof and waterproof effect, so as to effectively ensure Sealing property between square terminal box and lid so that square terminal box is connected even closer with lid, and make for a long time With rear, it will not damage easily, without often maintenance, topology layout is reasonable；The outer wall of sealing ring is arc shape, and on sealing ring Annular groove and lower annular groove in setting, are effectively increased the pliability of the sealing ring, when the sealing ring is possessed stress Screen resilience, makes the sealing property of the sealing ring of the structure stronger, and upper buffer stopper and lower buffer stopper have buffering surplus, can be preferably Bear in extrusion process, it is to avoid situation about deforming occurs in sealing ring, it is ensured that the service life of sealing ring；Upper annular groove Groove width is become larger from bottom land toward notch and the groove width of lower annular groove is become larger from bottom land toward notch, is further improved The pliability of sealing ring, so as to further ensure that the sealing property between square terminal box and lid, it is ensured that dust-proof anti- Water effect.In direction, the junction of cover plate and side plate is provided with reinforcement projection, and reinforcement projection includes the first arc being connected with each other Shape portion and the second curved portions, improve the bulk strength of lid, it is ensured that service life.

The utility model is further arranged to：The groove width of the holding tank is become narrow gradually from bottom land toward notch direction.

By using above-mentioned technical proposal, when sealing ring is squeezed, it is to avoid sealing ring runs out of holding tank, it is ensured that sealing What circle can be consolidated firmly is positioned in holding tank, so as to ensure that the sealing property between square terminal box and lid.

The utility model is further arranged to：The sealing ring employs silica gel material and is made.

By using above-mentioned technical proposal, with indeformable, high temperature resistant, acid and alkali-resistance, non-bloating feature, so that preferably Sealing ring is realized in long-time in use, will not damage easily, service life is extended.
