Description

Technical Field

[0001] The utility model relates to a stator end plate, in particular to a stator end plate with a terminal fixing structure. Background Art

[0002] A stator end plate is an end plate installed on both sides of the stator core. In the prior art, end plates are installed at both ends of the stator core by pressing. A number of bosses are provided on the end plate, and a number of grooves corresponding to the bosses are provided on the stator core. During installation, the end plate is pressurized by a press-fit device to press the bosses on the end plate into the grooves to complete the installation of the end plate. However, the end plates in the prior art are usually made of plastic, which can easily be damaged when the press-fit device is used to press the end plate. Once damaged, the end plate cannot be used any further and can only be removed from the stator core, replaced with a new end plate, and then pressed in again. To this end, a stator end plate with a terminal fixing structure is proposed. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and to provide a stator end plate with a terminal fixing structure.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a stator end plate with a terminal fixing structure, comprising an end plate body, a plurality of winding ends arranged on the end plate body for winding enameled wire, and a wire blocking plate arranged on the winding end; the invention is characterized in that it also includes a screw-on structure arranged on the end plate body to facilitate the installation of the end plate body on the stator core, and the screw-on structure includes a plurality of L-shaped screw-on terminals arranged on the end plate body.

[0008] The beneficial effects of the present invention are as follows: by setting the rotary connection structure, by setting an L-shaped rotary connection terminal on the end plate body, and setting an L-shaped rotary connection groove adapted to the rotary connection terminal on the stator core adapted to the end plate body, when installing the end plate body, it is only necessary to insert the rotary connection terminal into the rotary connection groove and rotate it so that the protruding part of the rotary connection terminal is stuck in the extended part of the rotary connection groove. At the same time, the extended part of the rotary connection groove squeezes the protruding part of the rotary connection terminal, driving the end plate body to cling to the surface of the stator core and making the end plate body and the stator core tightly matched. The installation is simple, convenient, fast and efficient.

[0009] By providing an inclined surface on the rotary terminal, when the protruding part of the rotary terminal is screwed into the extension part of the rotary groove, the inclined surface acts as a guide to avoid interference between the end face of one side of the rotary terminal and the rotary groove, which makes it difficult to screw and fix.

[0015] Hereinafter, we will further explain the stator end plate with a terminal fixing structure according to the present invention with reference to the accompanying drawings.

[0016] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0017] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0018] See Figure 1-4As shown in , a stator end plate with a terminal fixing structure includes an end plate body 1, a plurality of winding ends 2 provided on the end plate body 1 for winding enameled wire, and a wire blocking plate 3 provided on the winding ends 2; the stator end plate is characterized in that it also includes a screw-on structure provided on the end plate body 1 to facilitate mounting the end plate body 1 on the stator core 8, the screw-on structure including a plurality of L-shaped screw-on terminals 4 provided on the end plate body 1;

[0019] By setting the rotary connection structure, an L-shaped rotary terminal 4 is provided on the end plate body 1, and an L-shaped rotary groove 9 adapted to the rotary terminal 4 is provided on the stator core 8 adapted to the end plate body 1.

[0020] The L-shaped bent section of the rotary terminal 4 is the protruding portion described below. An L-shaped rotary slot 9 is provided on the stator core 8, and the bent section is the extended portion described below.

[0021] When installing the end plate body 1, it is only necessary to insert the rotary terminal 4 into the rotary groove 9 and rotate it so that the protruding portion of the rotary terminal 4 is stuck in the extended portion of the rotary groove 9. At the same time, the extended portion of the rotary groove 9 squeezes the protruding portion of the rotary terminal 4, driving the end plate body 1 to cling to the surface of the stator core 8 and making the end plate body 1 and the stator core 8 tightly fit. The installation is simple, convenient, fast and efficient.

[0022] In one embodiment, the rotary terminal 4 is further provided with an inclined surface 5 for guiding;

[0023] By providing an inclined surface 5 on the rotary terminal 4, when the protruding part of the rotary terminal 4 is screwed into the extension part of the rotary groove 9, the inclined surface 5 acts as a guide to avoid interference between the end face on one side of the rotary terminal 4 and the rotary groove 9, which makes it difficult to screw and fix. At the same time, the upper end face of the extension part of the rotary groove 9 squeezes the protruding part of the rotary terminal 4 along the inclined surface 5, driving the rotary terminal 4 to fit tightly with the stator core 8.

[0024] In one embodiment, the outer side of the end plate body 1 is also provided with a plurality of limit members 6 for indicating the position of the rotary terminal 4; during installation, the position of the rotary terminal 4 can be known by the position of the limit members 6, which facilitates the insertion of the rotary terminal 4 into the rotary groove 9 for easy assembly.

[0025] In one embodiment, the limiting member 6 is further provided with an arc-shaped positioning protrusion 7, and a limiting groove corresponding to the arc-shaped positioning protrusion 7 is provided on the stator core 8. After the end plate body 1 is screwed and fixed, the arc-shaped positioning protrusion 7 is driven to move to the limiting groove and is stuck in the limiting groove. The arc-shaped positioning protrusion 7 limits the circumferential position of the end plate body 1 on the stator core 8, thereby preventing easy rotation from causing the screw-on terminal 4 to disengage from the screw-on groove 9, causing the end plate body 1 to be disconnected from the stator core 8.

[0026] During the installation of the present invention: first, the position of the rotary terminal 4 is known according to the position of the limit member 6, and then the rotary terminal 4 is inserted into the rotary groove 9 on the stator core 8, and then the rotary terminal 4 is rotated. During the rotation process, the protruding part of the rotary terminal 4 is stuck in the extension part of the rotary groove 9, and the protruding part of the rotary terminal 4 is squeezed by the extension part and the end plate body 1 is tightly installed on the stator core 8. While rotating, the limit member 6 is driven to rotate. After rotating into position, the arc-shaped positioning protrusion 7 on the limit member 6 is stuck in the limited groove of the stator core 8 to complete the installation and fixation of the end plate body 1.

[0027] The protection scope of the present invention is not limited to the above embodiment and its variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment fall within the protection scope of the present invention.
