Detailed implementation manners

[0048] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the commodity or system comprising the said element.

[0052] Currently, the existing clamp assemblies have relatively high production costs and many potential safety hazards. Through the improvement of the clamp, the present invention provides a clamp assembly, which includes: a clamp buckle, a clamp and a piercing terminal, etc. The clamp assembly of the present invention can safely and reliably connect the power supply wire to the winding lead after the cooperation and assembly of the clamp buckle, the clamp and the piercing terminal, and the cost of this clamp assembly is relatively low, and the production and processing procedures are simple.

[0053] To further elaborate on the technical solutions in the present invention, the following specific embodiments are provided in conjunction with Figures 1-12 as shown.

[0054] Embodiment 1

[0055] In this embodiment, a clamp assembly is provided, and the clamp assembly includes:

[0056] As Figures 1-6 shown, a clamp buckle 1 and a clamp 2, the clamp buckle 1 has a circuit layout wall surface, and the clamp 2 has a circuit clamping wall surface that cooperates with the wiring wall surface; wherein a first wiring groove penetrating through both sides of its wall surface is formed on the circuit layout wall surface and / or a second wiring groove penetrating through both sides of its wall surface is formed on the circuit clamping wall surface;

[0057] A piercing terminal 3, the piercing terminal 3 is arranged in the first wiring groove, or the piercing terminal is arranged in the second wiring groove, or the piercing terminal 3 is arranged in the groove formed by the cooperation of the first wiring groove and the second wiring groove; the piercing terminal 3 includes: a wire skin crimping portion for fixing the wire skin of the power supply wire 4 and a wire core crimping portion for fixing the connection between the wire core of the power supply wire and the winding lead.

[0058] In this embodiment, the wire clamp assembly uses a piercing terminal to connect the power line and the winding lead, and the wire clamp buckle 1 and the wire clamp cooperate to achieve the encapsulation and fixation of the connection point. There is no need to adopt the fixing method of soldering the wire head. The fixing method of this wire clamp assembly is more reliable and also solves the problem of insufficient pulling force of the lead wire. In addition, the wire clamp assembly in this embodiment has effective protection measures for the wire head. Combined with the injection molding structure of the motor stator, it can effectively protect the exposed wire head from the impact of the plastic encapsulation material and will not cause quality hazards such as wire breakage.

[0059] In some alternative ways, since three groove design methods are provided in this embodiment, that is, a first wiring groove is set as a groove on the circuit layout wall surface of the wire clamp buckle 1 and cooperates with the circuit clamping wall surface of the wire clamp 2; or a second wiring groove is set as a groove on the circuit clamping wall surface of the wire clamp 2 and cooperates with the circuit layout wall surface of the wire clamp buckle 1; or the first wiring groove and the second wiring groove cooperate to form a complete groove. The above three methods can all realize the fixed connection of the power line and the winding lead, and use the groove to separate the connection point of the power line and the winding lead from the outside to achieve the isolation protection of the connection point.

[0060] Furthermore, the first wiring groove and / or the second wiring groove can both be set to be multiple, and multiple wiring grooves are arranged in parallel. As Figures 3-4 shown, when both the first wiring groove and the second wiring groove are set to three, they are distributed in parallel along the circuit layout wall surface and the circuit clamping wall surface. This arrangement method can enhance the insulation protection effect of the wire head, and the electrical clearance and creepage distance between the wire heads and between the wire head and the winding are sufficient, and there will be no hidden dangers such as phase-to-phase short circuit and leakage.

[0061] In this embodiment, the first wiring groove is a wire groove channel coaxially opened in three sections on the circuit layout wall surface; or, the second wiring groove is a wire groove channel coaxially opened in three sections on the circuit clamping wall surface; or, the first wiring groove and the second wiring groove cooperate to form a wire groove channel coaxially opened in three sections between the circuit layout wall surface and the circuit clamping wall surface.

[0062] Preferably, the wire groove channel includes: a front section, a middle section, and a rear section of the groove. As Figures 3-4As shown, there are three channels on the first wiring slot, including: the front channel 11 as the power cord passing slot, through which the wire skin section of the power cord can be passed; the middle channel 12 as the terminal slot, in which the piercing terminal 3 can be arranged; the rear channel 13 as the winding lead passing slot, through which the winding lead 51 can be passed. In this embodiment, the inner wall surface of the front channel is an arc surface; and / or, the middle channel is a rectangular slot; and / or, the inner wall surface of the rear channel is an arc surface. It should be noted that the second wiring slot can also be designed with a structure similar to that of the first wiring slot. At this time, the second wiring slot includes: the front slot 21 of the second wiring slot, the middle slot 22 of the second wiring slot, and the rear slot 23 of the second wiring slot. The inner wall surface design of this slot can make full contact with the power cord and the winding lead, and provide a suitable placement space for the piercing terminal.

[0063] In some alternative ways, such as Figures 5-6 As shown, the piercing terminal 3 includes a wire skin crimping part 31 and a wire core crimping part 32. Preferably, the wire skin crimping part 31 is a plate-like structure that can be bent and deformed, and a set of opposite side parts of the wire skin crimping part 31 can be bent towards the same side to form a wire skin arc crimping surface. The wire core crimping part 32 is a plate-like structure that can be bent and deformed, and a set of opposite side parts of the wire core crimping part 32 can be bent towards the same side to form a wire core arc crimping surface. Preferably, a thorn needle for piercing the paint film of the winding lead is formed on the wire core arc crimping surface.

[0064] After the winding lead 51 winds around the wire core 41 of the power cord, the wire skin crimping part 31 is pressed and clamped to the wire skin of the power cord to prevent the power cord from loosening; the piercing terminal uses the thorn needle 34 on the inner wall of the wire core crimping part 32 to pierce the paint film layer of the winding lead 51 wound around the wire core 41, so as to achieve the purpose of "winding lead - terminal - power cord" energization and conduction. Affected by the characteristics of difficult aluminum-copper soldering, the piercing terminal has higher reliability and simpler processing procedures compared with the traditional soldering connection method in the application of aluminum enameled wire, reducing quality risks such as wiring breakage and soldering false soldering.

[0065] In some alternative ways, the piercing terminal 3 further includes: a connecting part 33 connecting the wire skin crimping part 31 and the wire core crimping part 32. The connecting part 33 is a fan-shaped plate, and two side edges of the fan-shaped plate are bent towards the same side to form a side wall open cylindrical structure. The long arc edge of the fan-shaped plate is connected to the wire skin crimping part 31, and the short arc edge of the fan-shaped plate is connected to the wire core crimping part 32; or, the connecting part is a cylindrical structure with a gradually decreasing diameter from the first end to the second end of the connecting part, where the first end of the connecting part is connected to the wire skin crimping part 31, and the second end of the connecting part is connected to the wire core crimping part 32. The setting of the connecting part can prevent the deformation of the plate-like structure of one of the wire skin crimping part and the wire core crimping part when the other is pressed.

[0066] In some optional embodiments, the wire clamp buckle 1 of the wire clamp assembly further includes: a thermal protector mounting wall plate 14, which is arranged on one side of the wire clamp buckle 1 and extends toward a side away from the line arrangement wall. Figure 1 , Figure 11 As shown, the thermal protector mounting wall plate 14 of the nylon wire clamp buckle 1 can form a thermal protector mounting fixing groove with the outer wall of the injection-molded stator plastic packaging material 7, and the fixing and mounting process of the thermal protector 6 is simple and reliable.

[0067] In some optional modes, the wire clamp buckle 1 is detachably connected to the wire clamp 2. Specifically, a wire clamp mounting column 16 or a wire clamp mounting hole is provided on the line layout wall; correspondingly, a wire clamp mounting hole 24 or a wire clamp mounting column is formed on the line clamping wall; the wire clamp mounting column 16 cooperates with the wire clamp mounting hole 24 to realize the detachable connection between the wire clamp buckle 1 and the wire clamp 2. Preferably, as Figures 2-3 As shown, the wire clamp buckle 1 is provided with a plurality of wire clamp mounting posts, and the corresponding wire clamp is provided with a corresponding number of mounting holes, which are used for the splicing and fixing of the wire clamp buckle 1 and the wire clamp 2. The wire clamp buckle is provided with a plurality of wire clamp fixing holes 17, which correspond to the number and position of the wire clamp mounting step posts 91 on the motor stator frame 9, and are used for positioning and fastening when the wire clamp assembly is installed. It should be noted that the wire clamp mounting posts can also be replaced with structures such as hook fastening according to actual use requirements to enhance the splicing and fastening force.

[0068] In some optional embodiments, a card slot 15 is provided on the wire clamp buckle 1. The card slot 15 is located on the side opposite to the wall surface where the line is arranged, and can be connected with the circular ear of the stator core of the motor. It should be noted that the card slot 15 is equivalent to the nylon buckle 10, and the combination of the two can assemble and fix the semicircular stator core. Furthermore, the card slot is connected to the wire clamp buckle 1 through a card slot connecting portion 18. Figure 9As shown in the figure, the round-wound stator in the motor includes a semi-circular stator core 8, a stator skeleton 9, and windings wound around the stator core; there are two pairs of V-shaped stator core splicing ears 82 at the splicing joint of the semi-circular stator core, and a snap groove is provided on the inclined surface. The card slot 15 of the wire clip snap 1 can adopt a V-shaped card slot. Based on arranging the card slot 15 on the wire clip snap 1 through the card slot connecting part 18, in addition to realizing the function of locking the semi-circular plastic-sealed stator in a circular shape, the limiting part of the stator skeleton 9 (such as the bow-shaped step structure 92) can also limit the movement of the card slot 15, thereby realizing the limitation of the axial displacement of the wire clip snap 1. That is, by internally clamping the splicing circle ear of the stator core through the card slot 15, and through the external clamping and limiting cooperation between the card slot 15 and the bow-shaped step structure 92, the spatial position of the entire nylon wire clip assembly can be fixed. Preferably, after the bow-shaped step structure 92 of the stator skeleton 9 is installed correspondingly, a limiting space can be formed to limit the circumferential movement of the card slot 15 around the stator skeleton 9, and at the same time, a plurality of wire clip fixing holes 17 and wire clip installation step columns 91 are used to integrally fix the wire clip assembly.

[0069] In this embodiment, the wire clip snap is provided with multiple functional structures such as a power cord passing groove, a terminal groove, a winding wire head passing groove, an installation table column, a V-shaped snap, and a thermal protector installation wall plate; the wire clip snap 1 and the wire clip 2 are integrally injection-molded with a high flame-retardant insulating material such as nylon. After the wire clip snap 1 and the wire clip in the wire clip assembly are assembled, the wire head terminal part of the power cord is encapsulated in the terminal groove of the wire clip. The wire clip snap 1 and the wire clip effectively strengthen the insulation performance of the exposed wire head terminal part, and effectively prevent the quality hazard of wire breakage caused by the plastic-sealing material impacting the exposed wire head during the stator injection molding process. This wire clip assembly integrates multiple functions such as "power cord fixing, thermal protector clamping, semi-circular stator circular splicing, wiring wire head fixing and protection, wire clip fastening installation, and strengthening the insulation of conductive components", and combined with the application of the piercing terminal in the power cord wiring process, optimizes the product structure, reduces labor and material costs, and improves product quality.

[0070] Embodiment 2

[0071] In this embodiment, a motor is provided, and the motor includes: the wire clip assembly in Embodiment 1. Specifically, the wire clip snap 1 is provided with multiple functional structures such as a power cord passing groove, a terminal groove, a winding wire head passing groove, an installation table column, a V-shaped snap, and a thermal protector installation wall plate, and is integrally injection-molded with a high flame-retardant insulating material such as nylon. The piercing terminal uses the magnetic needle on the inner wall of the wire core crimping part to pierce the paint film of the winding wire head, so as to achieve the purpose of "winding enameled wire - terminal - power cord" energization and conduction. Affected by the characteristics of difficult aluminum-copper soldering, the piercing terminal has higher reliability and simpler processing procedures compared with the traditional soldering connection method in the application of aluminum enameled wire.

[0072] In addition to realizing the function of locking the semi-circular plastic-sealed stator into a complete circle, the card slot (V-shaped buckle part) combines with the "bow-shaped step structure" of the skeleton to limit the axial displacement of the buckle and fix the position of the wire clamp buckle 1 through the buckle connection part.

[0073] As Figures 1-11 shown, after the wire clamp buckle and the nylon wire clamp are assembled, the wire head terminal part of the power cord is encapsulated in the terminal slot of the wire clamp. The nylon wire clamp buckle and the nylon wire clamp effectively enhance the insulation performance of the exposed wire head terminal part and effectively prevent the quality hazard of wire breakage caused by the plastic-sealing material impacting the exposed wire head during the stator injection molding process.

[0074] The heat protector installation wall plate of the nylon wire clamp buckle forms a heat protector installation and fixing groove with the outer wall of the injection-molded stator plastic-sealing material, and the heat protector fixing installation process is simple and reliable.

[0075] Compared with the power cord lead connection structure of traditional plastic-sealed motors, the wire clamp assembly adopted by the motor in this embodiment has the advantages of simple structure, multiple functions, low assembly difficulty, high insulation performance, small volume, and low cost.

[0076] Furthermore, in this embodiment, an installation process of the motor when adopting the above wire clamp assembly is also provided. Specifically as follows: The first step is to assemble the skeleton and wind the wire on the semi-circular stator core; the second step is to assemble the nylon buckle 10 and the card slot 15 of the nylon wire clamp and make the core into a complete circle; the third step is to wind the wire core of the power cord and crimp the puncture terminal 3, assemble the lead and assemble the nylon wire clamp assembly; the fourth step is to install the stator plastic-sealing material 7 and the heat protector 6.

[0077] The exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, setting manners or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
