The utility model provides a junction box for directly connecting a low-voltage motor with a lead, which comprises a base wiring window. The junction box is characterized in that: the base wiring box is provided with an integrated junction box; a metal threaded flexible pipe is fixedly connected with the integrated junction box; a stator winding lead enters the integrated junction box through the base wiring window and is led out from the metal threaded flexible pipe. The junction box provided by the utility model is advantageous in that: the base of the junction box can be totally fitted with the wiring window of the motor base; a space with enough wire inlet holes and wiring holes is realized; good fitting and mounting with the metal threaded flexible pipe at wiring holes can be ensured; because mounting holes of the base are arranged in a square, a boss can rotate to a random surface selected from an upper surface, a lower surface, a left surface and a right surface through turning, thereby generating a certain guidance quality of the wiring. The integrated structure simplifies mounting steps and also reduces mounting cooperation. The cylindrical structure also saves mounting space.
Description
Technical field
The utility model relates to a kind of terminal box of the low voltage motor for direct lead wire.
Background technology
As shown in Figure 1, the structural representation of the terminal box of using for conventional low voltage motor, generally, all with sealing gasket 2, terminal block 4, binding post 5 and stuffing box etc., is divided into 6 liang of large parts of junction box seat 3 and connector cover.
The wiring process of general lead wire is: the lead wire 1 of stator winding is received on the binding post 5 of motor wire-connecting board 4, and then the cable 7 of feeder ear is received on binding post 5 by the stuffing box hole of terminal box, thereby meets the normal power-up of motor.
In order to meet some specific installation requirement of supplier, some low tension chance adopts direct lead wire, and (lead wire that is motor stator winding is long, directly draw and receive feeder ear from motor) method, this situation lead portion adopts metal threaded flexible pipe to protect conventionally, owing to need to meeting the installation of metal threaded pipe, generally can adopt two kinds of methods: one is to adopt terminal box, but remove the terminal block in terminal box, the parts such as binding post, stator winding lead wire is directly drawn by stuffing box hole, metal threaded flexible pipe is threaded connection on junction box seat, another kind is at the wiring window place of support, a flat board that is threaded hole to be installed directly to draw wiring, and metal threaded flexible pipe is threaded connection on flat board.
In practice, the wiring of first method is more attractive in appearance, and wiring is with guidance quality, but is subject to the impact of support wiring window size, and terminal box size can be bigger than normal sometimes, and the compacter occasion in installation site, often causes installing; Second method is relatively saved space, but overall appearance is affected, and wiring do not have guidance quality, is easy to cause damage once only depend on metal hose protection that lead wire bent angle part is collided with.
Summary of the invention
The purpose of this utility model is to provide a kind ofly to be taken into account aesthetic in appearancely in meeting the installation requirement of metal hose, has guidance quality, saves installing space, saves materials and prevents the terminal box of the multiple actions such as bent angle part lead wire is impaired.
In order to achieve the above object, the technical solution of the utility model has been to provide the direct lead wire terminal box of a kind of low voltage motor, comprise support wiring window, it is characterized in that: on support wiring window, be provided with integral type terminal box, metal threaded flexible pipe is fixedly connected with integral type terminal box, and stator winding lead wire enters integral type terminal box by support wiring window and draws via metal threaded flexible pipe.
Preferably, between described support wiring window and described integral type terminal box, be provided with sealing gasket.
Preferably, described integral type terminal box comprises the square half hollow out pedestal being fixedly connected with described support wiring window, on square half hollow out pedestal, be provided with hollow cylinder, be provided with the hollow boss being fixedly connected with described metal threaded flexible pipe in the side of hollow cylinder.
Preferably, arrange respectively an installing hole in four bights of described square half hollow out pedestal.
Adopt the effect of technical scheme of above-mentioned utility model as follows: the pedestal of (1) terminal box can fit like a glove with the wiring window of electric machine stand; (2) there is the space of enough entrance hole and wiring hole, and can ensure that wiring hole place can coordinate installation well with metal threaded flexible pipe; (3), because the installing hole of pedestal is square profile, by turning to the arbitrary face that can make boss forward upper and lower, left and right to, thereby make wiring with certain guidance quality; (4) integral structure had both been saved installation steps, reduced again to install to coordinate, and cylindrical structural has also been saved installing space.
This utility model can be widely used in the low voltage motor of direct lead wire, and it manufactures simple, saves materials, has certain economic benefit.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 2, the utility model provides a kind of low voltage motor direct lead wire terminal box, comprise support wiring window 8, on support wiring window 8, be provided with integral type terminal box 9, metal threaded flexible pipe 10 is fixedly connected with integral type terminal box 9, between support wiring window 8 and integral type terminal box 9, be provided with sealing gasket 11, stator winding lead wire 1 enters integral type terminal box 9 by support wiring window 8 and draws via metal threaded flexible pipe 10.
In conjunction with Fig. 3 to Fig. 5, described integral type terminal box 9 comprises the square half hollow out pedestal 9-1 being fixedly connected with described support wiring window 8.Square half hollow out pedestal 9-1 is subject to the inspiration of cap sequence, and its structure is similar to brim structure, can, according to the size of support wiring window 8, carry out its size of adjusted design, and the installing hole 9-4 on square half hollow out pedestal 9-1 can be square profile as far as possible.On square half hollow out pedestal 9-1, be provided with hollow cylinder 9-2.Junction box seat and connector cover that this hollow cylinder 9-2 is integrated, be similar to cap body and crown, columniform junction box seat than square can be larger save space, the size of hollow cylinder 9-2 will meet stator winding lead wire 1 and can be smoothly through, and wants to carry the thickness that metal threaded flexible pipe 10 is installed.Be provided with the hollow boss 9-3 being fixedly connected with described metal threaded flexible pipe 10 in the side of hollow cylinder 9-2.The height of the size of hollow boss 9-3 and hollow cylinder 9-2 all depends on the thickness of metal threaded flexible pipe.
