Description

Technical Field

[0001] The present invention relates to a shaded-pole motor, and in particular to a packaging method for a stator winding and a connection terminal of the shaded-pole motor. Background Art

[0002] The connection between the winding frame and the terminal blocks of a traditional shaded-pole motor cannot be assembled automatically by a machine and is generally assembled manually. This is because the traditional winding frame does not have slots for positioning the terminal blocks, and the wires wound on the winding frame cannot be directly passed through the winding frame to connect to the terminal blocks. Therefore, during assembly, the wires wound on the winding frame can only be guided to the terminal blocks by manual operation, and then the wires are welded to the terminal blocks; therefore, the production efficiency of the traditional assembly method is very low. Summary of the Invention

[0003] The object of the present invention is to provide a stator winding for a shaded-pole motor, which can realize automated production and improve assembly efficiency.

[0004] Another object of the present invention is to provide a packaging method for stator winding terminal blocks, which can realize automated assembly and improve assembly efficiency.

[0005] In order to achieve the above-mentioned purpose, the stator winding of the shaded-pole motor provided by the present invention includes a winding frame for winding the power supply wire and a wiring terminal, and mounting frames are provided at both ends of the winding frame, and positioning grooves are provided on the mounting frame. The wiring terminal is inserted into the positioning grooves, and open wire grooves are provided on the edges of both ends of the mounting frame so that the wires can pass through the wire grooves from the inside of the mounting frame and go around to the outside, and then be electrically connected to the wiring terminal.

[0006] Compared with the prior art, the present invention provides a positioning groove on the mounting frame so that the terminal blocks are inserted into the positioning groove to achieve positioning, and provides open wire grooves on both end edges of the mounting frame so that the wires can pass through the wire grooves from the inside of the mounting frame and go around to the outside and be electrically connected to the terminal blocks; since the positioning grooves can automatically position the terminal blocks, the wire grooves can guide the wires and direct them to the terminal blocks, so that the terminal blocks and the winding frame can be automatically assembled without manual wiring, thereby greatly improving production efficiency.

[0007] Preferably, the wire trough extends from the two end edges of the mounting frame toward the middle and extends to below the positioning slot, so that the wires can reach the terminal blocks in the shortest distance, thereby making the wire connection of the stator winding simpler and the structure more compact.

[0008] Preferably, a receiving cavity is provided below the positioning groove, the receiving groove is communicated with the wire groove and the positioning groove respectively, and the wire passes through the receiving cavity to be connected with the wiring terminal.

[0009] Preferably, the positioning slots include a plug-in slot for inserting the end pins of the terminal blocks and a glue-dispensing slot for securing the connecting pins of the terminal blocks, with the glue-dispensing slots being open and exposed outside the mounting frame. During assembly, the plug-in slots can be used to pre-position the terminal blocks, while the glue-dispensing slots can be used to inject glue to secure the terminal blocks. Therefore, both the positioning and securing processes can be mechanized, thereby achieving the purpose of automated assembly.

[0010] Preferably, the stator winding of the shaded-pole motor further includes a fuse, wherein one of the mounting frames has a mounting slot, and the fuse is mounted in the mounting slot. By providing the mounting slot, the fuse can be pre-installed in the mounting slot, and after the winding frame is wound, the fuse can be directly connected via wires, eliminating the need for manual placement. This makes the assembly process suitable for fully automated assembly, highly efficient, and safe and reliable.

[0011] Specifically, the mounting slot is located in the middle of the inner side of the mounting frame where the mounting slot is located.

[0012] Specifically, the mounting frame is provided with a wiring groove that communicates with the mounting slot and the positioning slot, respectively. The conductive lead of the fuse is disposed within the wiring groove and electrically connected to the terminal block on the mounting frame. The wiring groove can store and guide the conductive lead of the fuse, facilitating connection between the conductive lead and the terminal block, thereby facilitating automated assembly.

[0013] Preferably, the terminal comprises a terminal body, an end pin, a connecting pin, a sleeve, and an elastic pressing piece. The end pin and the connecting pin extend outward from the lower side of the terminal body. The sleeve is arranged on the upper side of the terminal body and allows the power line to pass through. The elastic pressing piece has an elastic portion and a pressing portion. The elastic force of the elastic portion drives the pressing portion to press against the wire. By being arranged on the sleeve, the sleeve can be used to sleeve the wire. By arranging the elastic portion and the pressing portion, the elastic portion drives the pressing portion to press the wire tightly, so that the wire can be directly and quickly connected to the terminal. Not only is the connection firm and stable, but the connection is also simple and convenient, and automated assembly can be achieved, effectively improving assembly efficiency.

[0014] Specifically, the pressing portion is tilted relative to the central axis of the sleeve, so that the wire can only be inserted from one end of the sleeve and is restricted from exiting from that end. By tilting the pressing portion, a push-up slope is formed on the side of the pressing portion. Therefore, when the wire is directly inserted into the sleeve, the pressing portion is automatically and elastically retracted by the push-up slope, thereby allowing the wire to be quickly and unobstructedly inserted and fixed. When the wire is withdrawn in the opposite direction, the pressing portion is caused to bend in the opposite direction and become stuck, thereby preventing the wire from accidentally escaping from the sleeve, greatly improving the stability and fixity of the wire connection.

[0015] A method for packaging a stator winding terminal comprises the following steps: inserting an end pin of the terminal into a positioning slot of a winding frame mounting frame so that a connecting pin of the terminal is located outside the glue dispensing slot; passing an end of an electric wire on the winding frame through the wire slot from the inner side of the mounting frame and winding it to the outer side, and entwining it with the connecting pin of the terminal; pressing the connecting pin into the glue dispensing slot of the winding frame; and injecting glue into the glue dispensing slot so that the end of the electric wire is fixed to the terminal and the terminal is fixed to the winding frame after the glue solidifies.

[0026] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0027] like Figures 1 to 6 As shown, the stator winding 100 of the shaded-pole motor of the present invention includes a winding frame 1 around which a power supply wire 200 is wound, and a terminal 2. The side surface of the winding frame 1 is in the shape of an I. Mounting frames 11 are provided at both ends of the winding frame 1. The mounting frames 11 are provided with at least two positioning slots 111. In this embodiment, one mounting frame 11 is provided with three positioning slots 111, and the other mounting frame 11 is provided with two positioning slots 111. The terminal 2 is inserted into the positioning slots 111. Open wire grooves 112 are provided at the edges of both ends of the mounting frame 11. Below the positioning slots 111 is a receiving cavity 113, which is connected to the wire groove 112 and the positioning slot 111 respectively, so that the wire 200 can pass from the inside of the mounting frame 11 through the wire groove 112 and around to the outside, and then pass through the receiving cavity 113 to be electrically connected to the terminal 2. The wire slots 112 extend from the two end edges of the mounting frame 11 to the middle and extend to below the positioning slots 111. This allows the wires 200 to reach the terminal blocks 2 in the shortest distance, making the wire connection of the stator winding 100 simpler and the structure more compact.

[0028] For example Figure 2 and Figure 3 As shown, the positioning groove 111 includes two insertion grooves 111a for inserting the two end pins 22 of the terminal block 2 and a glue dispensing groove 111b for fixing the connecting pin 23 of the terminal block 2. The glue dispensing groove 111b is open and exposed on the outside of the mounting frame 11. The insertion groove 111a is provided with a guide slope 111c at the notch to guide the insertion of the end pin 22 when inserting. During assembly, the insertion groove 111a can pre-position the terminal block 2, and the glue dispensing groove 111b can be used to inject glue to fix the terminal block 2. Therefore, the positioning and fixing processes can be achieved by mechanization, thereby achieving the purpose of automated assembly.

[0029] See also Figure 1 、 Figure 2 and Figure 4The stator winding 100 of the shaded-pole motor also includes a fuse 3. A mounting slot 114 is provided on the mounting frame 11 on which the two wiring terminals 2 are mounted. The mounting slot 114 is located in the middle of the inner side of the mounting frame 11, and the two positioning slots 111 are located on both sides of the mounting slot 114. The fuse 3 is mounted on the mounting slot 114. The mounting frame 11 is provided with a wiring slot 115 that is connected to the mounting slot 114 and the positioning slot 111 respectively. The conductive lead of the fuse 3 is arranged in the wiring slot 115 and is electrically connected to the wiring terminals 2 on the mounting frame 11. By providing the wiring slot 115, the wiring slot 115 can store the conductive lead of the fuse 3 and guide the conductive lead to facilitate the connection of the conductive lead with the wiring terminals 2, which is convenient for automated assembly. By setting the installation groove 114, the fuse 3 can be pre-installed in the installation groove 114. After the winding frame 1 is wound, the fuse 3 can be directly connected through a wire without manual placement. Therefore, it is suitable for fully automated assembly, with high assembly efficiency, and is safe and reliable.

[0030] For example Figure 2 and Figure 4 As shown, the inner side of the mounting groove 114 is open and exposed to the inner side of the mounting frame 11, and the upper side of the mounting groove 114 is an opening structure 114a. This allows the fuse 3 to quickly detect the temperature on the winding frame 1, making the detection faster and more accurate. The opening structure 114a allows the conductive lead of the fuse 3 to extend more easily into the wiring groove 115, thereby making the connection structure simpler and more compact. The opening structure 114a gradually narrows from top to bottom, so that the fuse 3 can be automatically guided into the mounting groove 114 during assembly, ensuring convenient and smooth assembly and improving assembly efficiency.

[0031] Please refer to Figure 7 、 Figure 8 and Figure 9The terminal block 2 includes a terminal body 21, two end legs 22, a connecting leg 23, a sleeve 24, and an elastic pressing piece 25. The terminal body 21, end legs 22, connecting leg 23, sleeve 24, and elastic pressing piece 25 are an integrally formed structure. The end legs 22 and the connecting leg 23 extend outward from the lower side of the terminal body 21; the connecting leg 23 is located between the two end legs 22; the connecting leg 23 is bent approximately 90 degrees relative to the terminal body 21 when not installed, and can be bent downward and flattened relative to the terminal body 21 after installation. The connecting leg 23 is provided with a recess 231 for winding the power cord 200. This allows the wire 200 to be more firmly wound around the connecting leg 23, preventing the wire 200 from falling off. The sleeve 24 is arranged on the upper side of the terminal body 21 and allows the power cord 300 to pass through. The central axis of the sleeve 24 is perpendicular to the extension direction of the end legs 22. The sleeve 24 is formed by stamping and bending the upper edge of the terminal body 21. The sleeve 24 is divided into two sections, front and back, with the elastic pressing piece 25 in the middle for pressing against the wire 300. The elastic pressing piece 25 comprises an elastic portion 251 and a pressing portion 252. One end of the elastic portion 251 is connected to the end of the sleeve 24, and the other end is connected to the pressing portion 252. The elastic force of the elastic portion 251 forces the pressing portion 252 to press against the wire 300. By being provided on the sleeve 24, the sleeve 24 can quickly sleeve the wire 300. By providing the elastic portion 251 and the pressing portion 252, the elastic portion 251 drives the pressing portion 252 to press the wire 300, so that the wire 300 automatically pushes away the pressing portion 252 when entering the sleeve 24, and the pressing portion 252 can automatically press the wire 300, thereby directly and quickly fixing it to the terminal block 2. Not only is the connection firm and stable, but the connection is also simple and convenient, which can realize automated assembly and effectively improve assembly efficiency. The side wall of the sleeve 24 has a protrusion 241 that is curved in the opposite direction to press the wire 300 together with the elastic pressing piece 25.

[0032] Combine Figure 7 and Figure 9Specifically, the pressing portion 252 is tilted relative to the central axis of the sleeve 24, so that the wire 300 can only be inserted from one end of the sleeve 24 and is restricted from exiting from that end. By tilting the pressing portion 252, a side surface of the pressing portion 252 forms a push-up slope 252a. Therefore, when the wire 300 is directly inserted into the sleeve 24, the push-up slope 252a causes the pressing portion 252 to automatically and elastically retract, allowing the wire 300 to be quickly and smoothly inserted and secured. When the wire 300 is withdrawn in the opposite direction, the pressing portion 252 bends in the opposite direction, becoming locked, thereby preventing the wire 300 from accidentally detaching from the sleeve 24 and significantly improving the stability and securement of the wire 300 connection. The side of the pressing portion 252 facing the sleeve 24 is provided with a curved surface that wraps around the wire 300. By providing the arc-shaped surface, the contact area between the pressing portion 252 and the electric wire 300 can be increased, thereby further improving the ability of the pressing portion 252 to prevent the electric wire 300 from falling off.

[0033] Compared with the prior art, the present invention provides a positioning groove 111 on the mounting frame 11 so that the terminal block 2 can be inserted into the positioning groove 111 to achieve positioning, and provides an open wire groove 112 on both end edges of the mounting frame 11 so that the wire 200 can pass through the wire groove 112 from the inside of the mounting frame 11 and go around to the outside and be electrically connected to the terminal block 2; since the positioning groove 111 can automatically position the terminal block 2, the wire groove 112 can guide the wire 200 and lead it to the terminal block 2, so that the terminal block 2 and the winding frame 1 can be automatically assembled without manual wiring, which greatly improves production efficiency.

[0034] like Figure 10 As shown, the packaging method of the stator winding terminal of the present invention includes the following steps:

[0035] Step S1, inserting the end pin 22 of the terminal block 2 into the positioning groove 111 of the mounting frame 11 of the winding frame 1, so that the connecting pin 23 of the terminal block 2 is located outside the glue dispensing groove 111b;

[0036] Step S2, passing the ends of the wires 200 on the winding frame 1 from the inner side of the mounting frame 11 through the wire groove 112 and winding them to the outer side, and winding them around the connecting pins 23 of the terminal blocks 2;

[0037] Step S3, pressing the connecting pin 23 into the glue dispensing groove 111b of the winding frame 1;

[0038] In step S4 , glue is injected into the glue dispensing groove 111 b , so that after the glue solidifies, the end of the wire 200 is fixed to the wiring terminal 2 and the wiring terminal 2 is fixed to the winding frame 1 .

[0039] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
