Abstract
The invention discloses a quick fixing structure of a plastic package alternating current motor protector, which comprises a protection box and a fixing column arranged on the insulation of a stator slot, wherein the protection box is of a semi-closed structure, a cavity for accommodating the protection box is formed, and a fixing hole matched with the fixing column is formed in the protection box. Through increase the fixed column on the slot insulation, the fixed column cooperates with the fixed orifices on the protection box, realizes the embedment of protector, not only convenient operation reduces production time simultaneously, reduction in production cost, can be used to install the protector that resets, also can be used to install the fuse.
Description
Technical Field
The invention relates to the technical field of motors, in particular to a quick fixing structure of a plastic-package alternating current motor protector.
Background
A motor protector, also called motor protector, is an electrical device for protecting a motor from faults such as overload, short circuit, undervoltage, overheat and the like. The motor protector can effectively protect the motor, prolong the service life of the motor protector and improve the stability and reliability of equipment.
The motor protector can be divided into an external installation and an internal installation according to a distribution mode, wherein the external installation is arranged on a motor shell, and a conduction and convection process exists from the heating of the motor to the heating of the shell. There is also a process from the heating of the housing to the action of the protector, so that the accuracy and reliability of this protection mode are relatively poor.
The external protector is required to be provided with a protector mounting bracket and a protective baffle on the stator shell, so that the local size of the motor can be increased, and the structural compactness of a final product is not facilitated.
The external protector is connected with the outgoing line of the motor, and because the external connection is realized, the external protector is fixed by a heat shrinkage tube, and compared with the internal protector, the external protector increases the production cost of the motor.
Disclosure of Invention
The invention aims to solve the technical problems that: the defect that prior art exists above is overcome, provides a make built-in fixed knot of protector constructs, through increase the fixed column on the groove insulation, the fixed column cooperates with the fixed orifices on the protection box, realizes the built-in of protector.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a quick fixed knot of plastic envelope alternating current motor protector constructs, includes the protection box and sets up the fixed column on the stator slot is insulating, the protection box be semi-closed structure, form the cavity that holds the protection box, and offered on the protection box with fixed column matched with fixed orifices.
Further, the fixed column is in interference fit with the fixed hole.
Further, a notch is formed in the top of the protection box and used for leading out pins of the protector.
Further, the notch opening is oriented to be consistent with the opening of the protection box.
Further, the notch and the opening of the protection box face to the side.
Furthermore, the protection box is provided with a round corner at the folded corner close to the coil so as to prevent the coil from being damaged.
The quick fixing structure of the plastic package alternating current motor protector has the beneficial effects that:
the protector box is designed, the protector box is fixed by adding the fixing column on the slot insulator, the protector box is clamped between the stator winding slots, and the two slots are formed in the upper side of the protector box to lead out the pins of the protector, so that the built-in fixation of the protector can be realized, the operation is convenient, the production time is reduced, the production cost is reduced, and the protector box can be used for installing a reset protector and also can be used for installing a fuse.

FIG. 1 is a schematic diagram of an external structure of a protector in the prior art;
FIG. 2 is a schematic view of the motor-mounted structure of the present invention;
FIG. 3 is a schematic diagram of the structure of the present invention;
in the figure: 1. the stator slot is insulated, 2. The protection box, 3. The protector, 4. The notch, 5. The fixing hole, 6. The fixing column.
Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the invention and therefore show only the structures which are relevant to the invention.
The quick fixing structure of the plastic package alternating current motor protector as shown in fig. 2 and 3 comprises a protection box 2 and a fixing column 6 arranged on a stator slot insulator 1, wherein the protection box 2 is of a semi-closed structure, a cavity for accommodating the protection box 2 is formed, and a fixing hole 5 matched with the fixing column 6 is formed in the protection box 2.
The fixed column 6 is in interference fit with the fixed hole 5.
The top of the protection box 2 is provided with a notch 4 for leading out pins of the protector.
The opening orientation of the notch 4 is consistent with the opening orientation of the protection box 2.
The openings of the notch 4 and the protection box 2 face to the side.
The protection box 2 is provided with a round corner at the folded corner close to the coil so as to prevent the coil from being damaged.
The invention designs a protector box, the protector box is fixed by adding the fixing column on the slot insulator, the protector box is clamped between the stator winding slots, and two slots are arranged above the protector box to lead out the pins of the protector, so that the built-in fixation of the protector can be realized, the operation is convenient, the production time is reduced, the production cost is reduced, and the protector box can be used for installing a reset protector and also can be used for installing a fuse.
With the above-described preferred embodiments according to the present invention as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present invention. The technical scope of the present invention is not limited to the description, but must be determined according to the scope of claims.
