Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.
Fig. 1 and Fig. 2 schematically shows a kind of terminal box 100 according to prior art, and this terminal box 100 is mainly used for the terminal box of motor.It is usually located at the rear end cap place of motor, is arranged at the outside of the housing 200 of motor.In this Fig. 1 and Fig. 2, in order to illustrate the structure of junction box better, be removed for the cap closing described terminal box shell 10.As shown in Figure 1, terminal box 100 comprises a terminals component 20.Terminals component 20 is typically provided with multiple binding post (showing six binding posts in the present embodiment), for the connection of cable.In addition, terminal box 100 also comprises a terminal box shell 10 having protection terminals component 20 and act on, and terminals component 20 is surrounded by described housing 10 and protects.The wall portion 16 that housing 10 can comprise a bottom 14 and stretch out from described bottom 14.Terminals component 20 stretches out through a through-hole section 13 on the bottom 14 of housing 10.The wire hole 30 for power supply lead wire and encoder lead-in wire of cable from the housing 200 being arranged on motor stretches out, and is connected with terminals component 20.Wherein through-hole section 13 is communicated with described wire hole 30.Wherein when as described in Figure, when the bottom 14 of the housing of terminal box 100 is constructed to a diapire 15, through-hole section 13 is constructed to a through hole 13 on diapire 15.
Terminal box shell 10 is all provided with the Glan head bore 11 that at least one penetrates described terminal box shell 10 usually, and the cable for outside extend in terminal box 100 be connected with terminals component 20 through described Glan head bore 11, and then electrical connection motor.When user uses in strict accordance with the explanation of manufacturer, gland head 12 should be used.Through hole current supply cable in gland head 12 passes, and is then connected in Glan head bore 11, realizes the protection of waterproof.Then market at home, especially in the market of low side, actual operating personnel can not use gland head 12 sometimes, but are directly connected through Glan head bore 11 by cable.Like this, when environment for use has water, such as out of doors rainfall time, water can be entered in terminal box 100 by Glan head bore 11, and then enters into the inside of motor along through-hole section 13 and wire hole 30.
In order to improve this situation, the utility model has carried out corresponding improvement.Participate in Fig. 3 and Fig. 4 to show according to a kind of execution mode of the present utility model.Wherein can see, when the through-hole section 13 of the bottom 14 of terminal box shell 10 be one can be communicated with wire hole 30 through hole 13, add a circle perisporium 40 round wire hole 30.Advantageously, this circle perisporium 40 also surrounds terminals component 20, for it provides waterproofing protection.Wherein, in this embodiment, perisporium 40 is arranged on the diapire 15 of the bottom 14 of terminal box shell 10, and namely this perisporium 40 is also arranged around through hole 13.In order to can not directly by the inside of the through hole 13 that is positioned on bottom 14 and the housing 200 that flow into motor when there being water to be entered into the inside of terminal box 100 by Glan head bore 11, the height H 2 of perisporium 40 is arranged, makes the top of this perisporium 40 higher than the Glan head bore 11 minimum edge 111 nearest apart from bottom 14.That is, make perisporium 40 as illustrated in the drawing height H 2 be greater than the distance h1 of lowest edge place 111 apart from bottom 14 of Glan head bore 11.Like this, even if there is water to enter into the inside of terminal box 100 by Glan head bore 11, water can not have the top of perisporium 40 yet.Thus, even if operating personnel forget installation gland head, perisporium 40 also can prevent water to enter into the inside of the housing 200 of motor in the presence of water.Perisporium 40 can be set to be integrally formed with the bottom 14 of described terminal box shell 10, also independently can arrange with bottom 14.When perisporium 40 and bottom 14 are two separable independently parts, both can be interconnected by modes such as bonding, welding.Perisporium 40 can by elastomeric material, and such as rubber, plastics etc. are made, and also can be made up of metal material.
Fig. 5 shows the terminal box 100 according to another kind of execution mode of the present utility model.Be that perisporium 40 is not be arranged on the diapire 15 of bottom 14 with the difference of the execution mode shown in Fig. 3-4, but be set directly on the housing 200 of motor.Similarly, the top of perisporium 40 should higher than the minimum edge of Glan head bore 11.Perisporium 40 can be set to be integrally formed with the housing 200 of motor, also independently can arrange with housing 200.When perisporium 40 and housing 200 can be two separable independently parts, both can be interconnected by modes such as bonding, welding.Perisporium 40 can by elastomeric material, and such as rubber, plastics etc. are made, and also can be made up of metal material.
Fig. 6 shows the terminal box 100 according to another kind of execution mode of the present utility model.In this embodiment, terminal box 100 is set to directly be connected with the housing 200 of motor more simply, in other words, the through-hole section 13 on the bottom 40 of terminal box shell 10 is set to overall opened portion 13 of opening wide, and the wall portion 16 of terminal box shell 10 is directly connected with housing 200.So, opened portion 13 is also communicated with wire hole 30.Perisporium 40 can be set directly on housing 200.Similarly, the top of perisporium 40 should higher than the minimum edge of Glan head bore 11.Perisporium 40 can be set to be integrally formed with the housing 200 of motor, also independently can arrange with housing 200.When perisporium 40 and housing 200 can be two separable independently parts, both can be interconnected by modes such as bonding, welding.Perisporium 40 can by elastomeric material, and such as rubber, plastics etc. are made, and also can be made up of metal material.
Although do not illustrate in the accompanying drawings, it is envisioned that the terminal box 100 that the utility model proposes can also be used for except motor, other needs the device of terminal box.Therefore, housing 200 is also not limited to the housing of motor, and can be any housing being provided with the device of terminal box.
Be to be understood that, although this specification describes according to each embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present utility model and principle, amendment and combination, all should belong to the scope of the utility model protection.
