Description

Lug plate

Technical field

The utility model is related to a kind of lug plates.

Background technology

As Fig. 1 and Fig. 2 jointly shown in, driving motor high-voltage connection piece 1 includes mounting portion 11, interconnecting piece 13 and tubulose Mounting portion 11 and conducting wire fixed part 14 are fixed together by conducting wire fixed part 14, interconnecting piece 13, and mounting portion 11 is equipped with peace Hole 12 is filled, lug plate 1 is fixed on motor or controller by the screw across mounting hole 12.Lug plate 1 is made of metal material. When crimping cable, the plain conductor 21 of cable 2 is inserted into conducting wire fixed part 14, and plain conductor 21 is fixed on conducting wire fixed part 14 In, the insulated hull 22 of cable 2 is resisted against on conducting wire fixed part 14, influences high-voltage isulation effect to prevent plain conductor 21 from leaking out.

But in actual use, it is easier to that relative displacement occurs between plain conductor 21 and insulated hull 22, causes absolutely There are gaps between edge skin 22 and conducting wire fixed part 14, i.e., as shown in Figure 2.When 21 exposed length of plain conductor is longer, it will shadow The high-voltage isulation to circuit is rung, and then serious failure occurs.

The reason of generation relative displacement, may be between plain conductor 21 and insulated hull 22：In storing process temperature occur compared with Big variation, leads to the displacement caused by expanding with heat and contract with cold of insulated hull 22, or due to attached between plain conductor 21 and insulated hull 22 Put forth effort it is too small cause cable 2 vibrated in transportational process caused by displacement or operator adjust conducting wire when crimping cable 2 The power applied when fixed part 14 leads to the displacement occurred between insulated hull 22 and plain conductor 21 or other reasons.

Invention content

Technical problem to be solved in the utility model is：A kind of lug plate is provided, which will not allow plain conductor It leaks out, ensures insulation effect.

In order to solve the above technical problems, the technical solution of the utility model is：

Lug plate includes the mounting portion of plate, the conducting wire fixed part of tubulose and is fixed positioned at the mounting portion and the conducting wire Interconnecting piece between portion, the mounting portion are equipped with mounting hole, and insulated hull of the outer end equipped with tubulose of the conducting wire fixed part is solid Determine portion, the internal diameter of the insulated hull fixed part is more than the internal diameter of the conducting wire fixed part.

Preferably, the transition part of taper is additionally provided between the conducting wire fixed part and the insulated hull fixed part, it is described Campanula halleri Halleri is collectively formed with the insulated hull fixed part in transition part.

Preferably, the insulated hull fixed part is equipped with peep hole.

Preferably, there are one peep hole settings, two or more.

Preferably, the inner surface of the insulated hull fixed part is circumferentially with multiple protrusions.

Preferably, multiple protrusions are uniformly distributed.

After using above-mentioned technical proposal, the utility model has the beneficial effects that：

Since the outer end of conducting wire fixed part is equipped with the insulated hull fixed part of tubulose, the internal diameter of insulated hull fixed part is more than conducting wire The internal diameter of fixed part；When crimping cable, the plain conductor of cable is fixed in conducting wire fixed part, and the insulated hull of cable is fixed on absolutely In edge skin fixed part, relative displacement is not will produce between plain conductor and insulated hull, plain conductor will not leak out, insulation effect It is good, it avoids that serious failure occurs.

Since insulated hull fixed part is equipped with peep hole, peep hole can observe the crimping length of insulated hull, and insulated hull is solid Fixed secured, insulation effect is good, ensures product quality.

Since the inner surface of insulated hull fixed part is circumferentially with multiple protrusions so that the elastic material of insulated hull has deformation Space, when crimping, will not destroy insulated hull, and insulated hull fixation.

Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model, and it is not used in restriction the utility model.

As Fig. 3, Fig. 4 and Fig. 5 jointly shown in, a kind of lug plate, mounting portion 11 be equipped with mounting hole 12, pass through mounting hole 12 Screw lug plate 1 is fixed on motor or controller, the side of mounting portion 11 is equipped with interconnecting piece 13, and interconnecting piece 13 connects There are the conducting wire fixed part 14 of tubulose, the outer end of conducting wire fixed part 14 to be equipped with the transition part 18 of flaring out, transition part 18 is taper, Transition part 18 is connected with the insulated hull fixed part 15 of tubulose, and the internal diameter of insulated hull fixed part 15 is more than the interior of conducting wire fixed part 14 Campanula halleri Halleri, mounting portion 11, interconnecting piece 13, conducting wire fixed part 14, mistake is collectively formed in diameter, transition part 18, insulated hull fixed part 15 It crosses portion 18 and insulated hull fixed part 15 is wholely set.

As Fig. 3, Fig. 4 and Fig. 5 jointly shown in, insulated hull fixed part 15 be equipped at least two peep holes 16, peep hole 16 It is uniformly arranged, the insertion depth of insulated hull 22 is observed by peep hole 15, to ensure the crimping length of insulated hull 22, ensure insulation The fixed effect of skin 22.
