Detailed Description

The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 4, a motor junction box 100 of the present embodiment includes an upper box 110 and a lower box 120 located below the upper box 110, where the lower box 120 is fixedly connected to a side of a bottom plate of the upper box 110 by welding or bonding, that is, the lower box 120 is located below the upper box 110 and close to a side of the bottom plate 111 of the upper box 110, the upper box 110 and the lower box 120 are rectangular boxes shown in fig. 1 to 4 as an example, and an entirety of the upper box 110 and the lower box 120 is in a horizontal L shape. The lower box 120 is provided with a top opening 121 communicated with the inner space of the lower box 120, meanwhile, a first wiring port 122 is arranged on one side plate of the lower box 120, the top opening 121 can be formed on the top plate of the lower box 120, or the top plate of the lower box 120 is directly omitted, so that the lower box 120 is in an open box shape with an open top, in the embodiment, the upper box 110 is covered above the lower box 110, the top opening 121 is formed directly by adopting the second mode, so that the material is saved, and the processing is convenient; the bottom plate 111 of the upper box 110 is provided with a through hole 112 correspondingly arranged with the top opening 121 to communicate the top opening 121 with the inner space of the upper box 110, so that a lead in the upper box 110 can penetrate into the lower box 120, or the lead in the lower box 120 penetrates into the upper box 110 to facilitate wiring, the bottom plate 111 of the upper box 110 is further provided with a second wiring port 113 communicated with the inner space of the upper box 110, the second wiring port 113 is positioned at one side of the lower box 120, the second wiring port 113 is used for correspondingly communicating the second wiring port 113 with the wiring port on the motor when the motor junction box 100 is installed in place on the motor, so that the lead in the motor is led into the upper box 110 to facilitate wiring operation.

As described above, the motor junction box 100 of the present embodiment is not a conventional rectangular box shape, but is divided into the upper box 110 and the lower box 120, the lower box 120 is located at a lower side of the upper box 110, in the case of securing the motor junction box 100 with a sufficient internal wiring space, the height h1 of the upper box 110 can be reduced accordingly, the lost internal wiring space can be compensated by the lower box 120, the height h2 of the lower box 120 can be increased, and when the motor junction box 100 is installed on the top of the motor, only the upper case 110 may be disposed above the top of the motor housing, the lower case 120 may be suspended at the side of the motor housing, the lower case 120 does not occupy the installation space above the top of the motor housing, only the upper case 110 occupies the installation space in the height direction, accordingly reducing the installation height of the motor junction box 100 on the motor, thereby realize reducing the whole height of motor, make the motor can install in narrower and narrower space.

Further, the height h1 of the upper box 110 is smaller than the height h2 of the lower box 120, as shown in fig. 1 and 3, so that the space occupied by the upper box 110 is reduced as much as possible, the overall height of the motor is further reduced, and the motor can be conveniently installed in a narrow space.

In this embodiment, the first wire connection port 122 of the lower case 120 faces away from the second wire connection port 113 of the bottom plate 111 of the upper case 110, so that the first wire connection port 122 and the second wire connection port 113 are as far apart as possible to facilitate wire connection or maintenance operation.

The motor junction box usually adopts the welded mode to set firmly in the top of motor among the prior art, and it is inconvenient to dismantle, and still be equipped with a plurality of mounting holes 114 that are located second wiring mouth 113 periphery on the bottom plate 111 of last box 110 in this embodiment, sets firmly motor junction box 100 at the top of motor through bolt-nut connected mode, and convenient the dismantlement is convenient for maintain and the wiring.

In order to facilitate the opening of the upper box 110, the upper box is enclosed by an upper cover 115 and a box body 116, the upper cover 115 and the box body 116 are detachably and fixedly connected, for example, by adopting a screw connection or a snap-fit connection, and at this time, the through hole 112 and the second wire connecting port 113 are both disposed on the bottom plate of the box body 116.

This embodiment has still proposed a motor 200, refer to fig. 5, including motor housing 210 and the motor shaft 220 that stretches out in a motor housing 210 lateral part, motor housing 210's top is formed with motor wiring mouth 211, and motor housing 210's top has set firmly motor terminal box 100, and the concrete structure of motor terminal box 100 refers to the utility model discloses the description of the embodiment of motor terminal box and attached fig. 1 to 4, no longer redundantly describes here. The upper box 110 of the motor junction box 100 is located above the top of the motor housing 210, the bottom plate 111 of the upper box 110 is attached to the top of the motor housing 210, the second wiring port 113 on the bottom plate 111 is at least partially overlapped with the motor wiring port 211, so that a lead inside the motor is led into the upper box 110 through the motor wiring port 211 and the second wiring port 113 to be wired or maintained, and the lower box 120 is suspended on the side of the motor housing 210 and does not occupy the space above the top of the motor housing 210.

Because in the lateral space of the motor housing 210, the partial space in the space on the side of the motor shaft 220 is idle, in order to fully utilize the partial space, the lower box 120 is located on the side of the motor shaft 220, that is, the lower box 120 and the motor shaft 220 are located on the same side of the motor housing 210, and the axial direction of the first wiring port 122 is parallel to the axial direction of the motor shaft 220, so that the wiring is conveniently passed through the first wiring port 122 from the front side of the motor.

As a specific example, as shown in fig. 5, a cable connector socket is installed at the first wire connection port 122, and then a cable connector 300 is installed, the cable connector 300 itself has a large volume, and if it is installed on the upper case 110, a large installation space is inevitably required, and it cannot be applied to small space installation, so that it is installed on the lower case 120, and the leads inside the motor sequentially enter the internal space of the upper case 110 through the motor wire connection port 211 and the second wire connection port 113, and then enter the internal space of the lower case 120 through the through hole 112 on the bottom plate of the upper case 110 and the top opening of the lower case 120, and then are connected to the cable connector 300 through the first wire connection port 122 of the lower case 120, and then are connected to external lines.

The motor 200 in this embodiment may be a variable frequency motor or other motor.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
