Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor lead wire connection structure with anti-detachment function. Background Technology

[0002] In the motor structure, the motor lead wire connection structure is used to electrically connect the conductive connecting piece of the internal coil of the motor to the external power line.

[0003] In the prior art, common motor lead wire connection structures typically include a plastic housing body, a connection terminal embedded in the plastic housing body, and a connection wire connected to the connection terminal. One end of the connection terminal is connected to a conductive connecting piece inside the motor, and the other end is connected to the connection wire, thereby realizing the electrical lead-out of the motor.

[0004] However, the existing connection terminal structure still has the following technical problems in actual use: the existing connection terminal structure lacks an effective fixing structure for the connection terminal, and the connection terminal mainly relies on its own spring support to prevent it from coming out of the plastic shell.

[0005] Because the plastic housing itself lacks a dedicated anti-detachment fixing structure, the connecting terminals are prone to loosening or even detaching from the plastic housing due to vibrations generated during motor operation, pulling on the connecting wires, and external forces during assembly. This can lead to poor contact or failure of the motor lead wire connection structure, affecting the normal operation and service life of the motor. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model proposes a motor lead wire connection structure with anti-detachment function.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A motor lead wire connection structure with anti-detachment function includes a housing, a coil frame body is disposed inside the housing, a conductive connecting piece is inserted on the coil frame body, and a connection end structure connected to the conductive connecting piece is disposed on the housing. The connection end structure includes a plastic shell body, a connection terminal embedded in the plastic shell body, and a connection wire connected to one end of the connection terminal. The other end of the connection terminal is connected to a conductive connection piece. The plastic shell body is provided with an installation cavity for the connection terminal to be inserted. One end of the installation cavity is open and forms an extension opening for the connection wire to extend out. The mounting cavity is provided with a blocking protrusion, and the connecting terminal is provided with a blocking plate. The blocking protrusion abuts against the blocking plate to restrict the connecting terminal from moving toward the protrusion. The plastic shell body is also fitted with a stop lock block, and the stop lock block is provided with a locking protrusion. The plastic shell body has first snap-fit ​​protrusions on both sides, and the stop locking block has first connecting slots on both sides that snap-fit ​​the first snap-fit ​​protrusions. When the stop locking block is snapped onto the plastic shell body, the locking protrusion is inserted into the mounting cavity from the protrusion and abuts against the connecting terminal.

[0008] Preferably, the plastic shell body is provided with a limiting groove for inserting one end of the connecting terminal. When one end of the connecting terminal is inserted into the limiting groove, the blocking boss abuts against the blocking plate. Through the above improvement, the connecting terminal moves only within a limited stroke when inserted until the blocking boss and the blocking plate abut precisely, realizing precise insertion control. This can prevent the terminal from damaging the inside of the plastic shell due to over-insertion, and also avoid the limitation failure caused by insufficient insertion. It ensures that the anti-disengagement structure of the blocking boss and the blocking plate is accurately triggered, reduces the reliance on manual insertion judgment, and effectively improves assembly consistency and anti-disengagement reliability.

[0009] Preferably, the mounting cavity is provided with a mounting groove, and the blocking piece is slidably disposed within the mounting groove. Through the above improvements, the mounting groove provides a precise sliding guide path for the blocking piece, allowing the blocking piece to slide smoothly along the groove and accurately abut against the blocking boss when the connecting terminal is inserted. This avoids limit failure due to offset or jamming, ensuring that the connecting terminal moves along a predetermined trajectory each time it is inserted, improving assembly consistency, and preventing the connecting terminal from being misaligned and scratching the plastic shell body. It also ensures that the anti-disengagement structure of the blocking boss and the blocking piece can be stably and reliably triggered, further improving the long-term stability of the product.

[0010] Preferably, one end of the connecting terminal is provided with a clamping piece for connecting and fixing the connecting wire, and the other end is provided with a plug-in slot. A retaining spring is provided in the plug-in slot. The conductive connecting piece is inserted into the plug-in slot and abuts against the retaining spring. The locking protrusion abuts against the bottom of the clamping piece. With the above improvements, the clamping piece at one end of the connecting terminal is used to fix the connecting wire, and the plug-in slot at the other end, together with the retaining spring, forms a reliable electrical contact with the conductive connecting piece to connect the motor coil and the external circuit, so as to realize the stable transmission of current. The locking protrusion abuts against the bottom of the clamping piece to form a secondary limit on the terminal, preventing it from coming out along the protrusion direction, effectively avoiding wire loosening or terminal displacement, and improving the electrical contact reliability and pull-out resistance of the overall connection structure.

[0011] Preferably, the height of the first snap-fit ​​protrusion gradually increases along the insertion direction of the stop lock block, forming a first guide slope. Through the above improvements, the first guide slope slides with the corresponding part inside the plastic shell body during assembly, guiding the stop lock block to be inserted smoothly, effectively reducing insertion resistance, avoiding jamming or scratching of the plastic shell and terminals. When the stop lock block is pushed into the predetermined position, the snap-fit ​​protrusion passes over the mating part and resets to engage, ensuring that the snap-fit ​​is in place, effectively preventing the stop lock block from loosening in the opposite direction due to vibration or external force, and improving the ease of assembly and the durability of locking.

[0012] Preferably, the coil frame body is provided with a locking cover, the locking cover is provided with a connecting post extending in the horizontal direction, the coil frame body is provided with a connecting hole for the connecting post to be inserted, and the locking cover has a snap hook extending in the vertical direction. The plastic shell body has second snap protrusions on both sides that engage with the snap hooks. Through the above improvements, the connecting post on the locking cover is inserted into the connecting hole of the coil frame body to achieve initial horizontal positioning. At the same time, the snap hook engages with the second snap protrusions on both sides of the plastic shell body to form a vertical locking fixation, connecting the coil frame and the plastic shell body into one unit through the locking cover. This effectively constrains the relative displacement of the two in multiple directions, preventing the connection end structure from loosening or detaching due to vibration or external impact, and further improving the assembly stability and long-term reliability of the overall structure.

[0013] Preferably, the inner wall of the outer shell abuts against the locking cover and restricts the connecting post from disengaging from the connecting hole. Through the above improvements, the inner wall of the outer shell abuts against the locking cover, forming an external pressing limit on the locking cover, thereby effectively restricting the connecting post from disengaging from the connecting hole. The secondary constraint on the locking cover is achieved by utilizing the assembly relationship of the outer shell itself, further enhancing the connection stability between the coil frame body and the connecting end, preventing the locking cover from loosening due to vibration or external impact, and ensuring the long-term reliability of the internal electrical connection.

[0014] Preferably, the coil frame body is provided with limiting protrusions, and the limiting protrusions form a positioning groove. The plastic shell body is placed in the positioning groove, and the limiting protrusions abut against both sides of the plastic shell body. Through the above improvements, the plastic shell body is stably embedded in the positioning groove, effectively restraining its horizontal displacement or shaking, ensuring the relative positional accuracy between the plastic shell body and the coil frame body, and preventing the plastic shell body from shifting due to vibration or external impact, which would affect the insertion and mating of the conductive connecting piece, further improving the overall structural stability and the reliability of the electrical connection.

[0015] Preferably, the plastic shell body is provided with an installation alignment groove, which faces the coil frame body. The coil frame body is provided with an alignment protrusion, which is inserted into the installation alignment groove. Through the above improvements, the installation alignment groove on the plastic shell body faces the coil frame body, and the alignment protrusion is inserted into the installation alignment groove, realizing foolproof installation and ensuring that the plastic shell body can only be inserted in the correct direction, avoiding reverse installation or misalignment.

[0016] Preferably, the second snap-fit ​​protrusion is provided with a second guide slope, which improves the smoothness of the connection between the locking cover and the plastic shell body.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects: By setting a blocking protrusion inside the plastic shell and a blocking piece abutting against it on the connecting terminal, a first anti-detachment structure is formed, which effectively restricts the movement of the connecting terminal toward the protrusion. The stop locking block that is snapped onto the connecting terminal inserts into the protrusion through its locking protrusion and abuts against the terminal, forming a second anti-detachment structure. The dual anti-detachment mechanism significantly improves the reliability of terminal fixation. Even if the terminal's own spring sheet undergoes plastic deformation or fatigue failure due to long-term use or external force pulling, it can still ensure that the connecting terminal will not come out of the plastic shell, avoiding the risk of broken or poor contact of the connecting wire.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0021] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, a motor lead wire connection structure with anti-detachment function includes a housing 1, a coil frame body 2 is provided inside the housing 1, a conductive connecting piece 3 is inserted on the coil frame body 2, and a connection end structure 4 connected to the conductive connecting piece 3 is provided on the housing 1.

[0022] Specifically, the connection end structure 4 includes a plastic shell body 101, a connection terminal 102 embedded in the plastic shell body 101, and a connection wire 103 connected to one end of the connection terminal 102. The other end of the connection terminal 102 is connected to the conductive connecting piece 3. The plastic shell body 101 is provided with a mounting cavity 104 for the connection terminal 102 to be inserted. One end of the mounting cavity 104 is open and forms an extension port 109 for the connection wire 103 to extend out.

[0023] Furthermore, a blocking boss 105 is provided inside the mounting cavity 104, and a blocking piece 106 is provided on the connecting terminal 102. The blocking boss 105 abuts against the blocking piece 106 to form a first anti-disengagement structure, thereby restricting the movement of the connecting terminal 102 toward the protrusion 109. A stop locking block 107 is snapped onto the plastic shell body 101, and a locking protrusion 108 is provided on the stop locking block 107. The locking protrusion 108 is inserted into the mounting cavity 104 from the protrusion 109 and abuts against the connecting terminal 102. The stop locking block 107, which is snapped onto the plastic shell body 101, inserts into the protrusion 109 through its locking protrusion 108 and abuts against the connecting terminal 102, forming a second anti-detachment structure. The dual anti-detachment mechanism significantly improves the reliability of the fixing of the connecting terminal 102. Even if the spring of the connecting terminal 102 itself undergoes plastic deformation or fatigue failure due to long-term use or external force pulling, it can still ensure that the connecting terminal 102 will not come out of the plastic shell body 101, avoiding the risk of the connecting wire 103 being broken or having poor contact.

[0024] Preferably, the first anti-disengagement structure formed by the blocking boss 105 and the blocking piece 106, and the second anti-disengagement structure formed by the locking protrusion 108 abutting against the connecting terminal 102, are located on opposite sides of the connecting terminal 102, so as to further improve the reliability and stability of fixing the connecting terminal 102.

[0025] In addition, the plastic shell body 101 is provided with first snap-fit ​​protrusions 201 on both sides, and the stop lock block 107 is provided with first connecting grooves 202 on both sides that snap-fit ​​with the first snap-fit ​​protrusions 201. The first snap-fit ​​protrusions 201 and the first connecting grooves 202 on the stop lock block 107 engage with each other to form a stable mechanical interlock structure. When the motor vibrates continuously or the connecting wire 103 is pulled by external force, the snap-fit ​​can effectively constrain the stop lock block 107 to move in the opposite direction of insertion, prevent it from loosening due to vibration or impact, and ensure that the stop lock block 107 always stays in the locked position, thereby maintaining the auxiliary limiting effect on the connecting terminal 102 for a long time and avoiding the risk of the connecting terminal 102 coming off.

[0026] Preferably, the height of the first snap-fit ​​protrusion 201 gradually increases along the insertion direction of the stop lock block 107, forming a first guide slope 401. During assembly, the first guide slope 401 slides and engages with the corresponding part inside the plastic shell body 101, guiding the stop lock block 107 to be inserted smoothly, effectively reducing insertion resistance and avoiding jamming or scratching of the plastic shell and terminals. When the stop lock block 107 is pushed into the predetermined position, the snap-fit ​​protrusion passes over the engagement part and resets to engage, ensuring that the snap-fit ​​is in place, effectively preventing the stop lock block 107 from loosening in the opposite direction due to vibration or external force, and improving the ease of assembly and the durability of locking.

[0027] like Figure 5 , Figure 8 As shown, as a further explanation of the installation method of the connecting terminal 102, a limiting groove 203 is provided in the plastic shell body 101 for inserting one end of the connecting terminal 102. The limiting groove 203 is set away from the direction of the protrusion 109. When one end of the connecting terminal 102 is inserted into the limiting groove 203, the blocking boss 105 abuts against the blocking piece 106, so that the connecting terminal 102 moves only within a limited stroke when inserted, until the blocking boss 105 and the blocking piece 106 just abut against each other, realizing precise insertion control. This can prevent the connecting terminal 102 from damaging the inside of the plastic shell body 101 due to over-insertion, and also avoid the limitation failure caused by insufficient insertion, ensuring accurate triggering of the first anti-detachment structure, reducing the reliance on manual insertion judgment, and effectively improving assembly consistency and anti-detachment reliability.

[0028] In addition, the limiting groove 203 limits the horizontal direction of the connecting terminal 102 to prevent the connecting terminal 102 from shifting horizontally, thereby improving the stability and reliability of the connection.

[0029] Furthermore, an installation groove 204 is provided in the mounting cavity 104, and the blocking piece 106 is slidably disposed in the installation groove 204. The installation groove 204 provides a precise sliding guide path for the blocking piece 106, so that when the connecting terminal 102 is inserted, the blocking piece 106 slides smoothly along the groove to accurately abut against the blocking boss 105, ensuring that the connecting terminal 102 moves along a predetermined trajectory each time it is inserted.

[0030] like Figure 8 , Figure 9 As shown, a further explanation of the implementation of the connection terminal 102 cooperating with the conductive connecting piece 3 and the connecting wire 103 is provided. One end of the connection terminal 102 is provided with a clamping piece 302 for connecting and fixing the connecting wire 103, and the other end is provided with a plug-in slot 301. An abutting spring piece 303 is provided in the plug-in slot 301. The conductive connecting piece 3 is inserted into the plug-in slot 301 and abuts against the abutting spring piece 303. The locking protrusion 108 abuts against the bottom of the clamping piece 302.

[0031] The clamping piece 302 at one end of the connecting terminal 102 is used to fix the connecting wire 103. The insertion slot 301 at the other end cooperates with the abutting spring 303 to form a reliable electrical contact with the conductive connecting piece 3, so as to connect the motor coil and the external circuit and realize the stable transmission of current. The locking protrusion 108 abuts against the bottom of the clamping piece 302 to form a secondary limit on the terminal, preventing it from coming out along the protrusion 109 direction, effectively avoiding wire loosening or terminal displacement, and improving the electrical contact reliability and pull-out resistance of the overall connection structure.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, as a further explanation of the locking embodiment of the plastic shell body 101, a locking cover 501 is provided on the coil frame body 2, a connecting post 502 extending in the horizontal direction is provided on the locking cover 501, a connecting hole 503 for inserting the connecting post 502 is formed on the coil frame body 2, and a snap hook 504 extending in the vertical direction is provided on the locking cover 501, and second snap protrusions 505 are formed on both sides of the plastic shell body 101 to snap with the snap hook 504.

[0033] After the locking cover 501 is installed, the connecting post 502 on the locking cover 501 is inserted into the connecting hole 503 of the coil frame body 2 to achieve initial horizontal positioning. At the same time, the snap hook 504 engages with the second snap protrusion 505 on both sides of the plastic shell body 101 to form a vertical locking fixation, connecting the coil frame body 2 and the plastic shell body 101 into one unit through the locking cover 501. This effectively constrains the relative displacement of the two in multiple directions, preventing the connection end structure 4 from loosening or detaching due to vibration or external impact, and further improving the assembly stability and long-term reliability of the overall structure.

[0034] In addition, the inner wall of the outer casing 1 abuts against the locking cover 501, forming an external pressing limit on the locking cover 501 and restricting the connecting post 502 from disengaging from the connecting hole 503, further enhancing the connection stability between the coil frame and the connecting end, preventing the locking cover 501 from loosening due to vibration or external impact, and ensuring the long-term reliability of the internal electrical connection.

[0035] Preferably, the second snap-fit ​​protrusion 505 is provided with a second guide slope 402 to improve the smoothness of the connection between the snap-fit ​​hook 504 and the second snap-fit ​​protrusion 505.

[0036] Preferably, the coil frame body 2 is provided with limiting protrusions 601, and the limiting protrusions 601 form a positioning groove 602. The plastic shell body 101 is placed in the positioning groove 602, and the limiting protrusions 601 abut against both sides of the plastic shell body 101, effectively restraining its horizontal displacement or shaking, ensuring the relative positional accuracy between the plastic shell body 101 and the coil frame body 2, and preventing the plastic shell body 101 from shifting due to vibration or external impact, which would affect the insertion and mating of the conductive connecting piece 3, further improving the overall structural stability and the reliability of the electrical connection.

[0037] Preferably, the outer surface of the plastic shell body 101 is provided with an installation alignment groove 603, which faces the coil frame body 2. The coil frame body 2 is provided with an alignment protrusion 604. During assembly, the alignment protrusion 604 is inserted into the installation alignment groove 603 to form a guiding fit, realize foolproof installation, and ensure that the plastic shell body 101 can only be inserted in the correct direction to avoid reverse installation or misalignment.

[0038] like Figures 3 to 9 As shown, as a further explanation of the assembly and installation of the connecting end structure 4, the independent assembly of the connecting end structure 4 is performed first: the connecting terminal 102 is placed into the mounting cavity 104 of the plastic shell body 101, and the blocking plate 106 slides along the mounting groove 204 until the blocking boss 105 abuts against the blocking plate 106, completing the first anti-detachment positioning. At the same time, one end of the connecting terminal 102 is placed into the limiting groove 203. Then, the stop locking block 107 is inserted from the protrusion 109, and the locking protrusion 108 abuts against the bottom of the clamping plate 302 of the connecting terminal 102. The first snap-fit ​​protrusion 201 engages with the first connecting slot 202 to form the second anti-detachment structure, completing the assembly of the connecting end structure 4.

[0039] After assembly, connect the connecting end structure 4 to the conductive connecting piece 3, that is, insert the conductive connecting piece 3 into the insertion slot 301 and abut against the abutting spring piece 303. Then, place the plastic shell body 101 into the positioning slot 602 of the coil frame body 2, insert the alignment protrusion 604 into the installation alignment groove 603 to prevent misalignment, and lock the locking hook 504 of the locking cover 501 with the second locking protrusion 505 to complete the installation.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
