Description

Technical Field

[0001] The utility model relates to the technical field of outlet wire sheaths, in particular to an integrated outlet wire clamp and a motor. Background Art

[0002] When the process model is mass-produced, the outlet sheath and the power cord are assembled into components. The employees place the outlet sheath on the stator outlet and weld the power cord to the stator assembly. Then, after matching it with the rotor assembly, they place an insulating ring to isolate the energized welding point from the rear end cover to prevent electrical safety.

[0003] In the prior art, the outlet sheath and the isolating ring are two separate materials. The isolating ring is used to avoid electrical safety hazards, and the outlet sheath is used to lead out the connecting wires. During mass production, these two materials are set in different processes, and relevant positions must be assigned actions to assemble them on the product. The production and assembly process is cumbersome, the labor input is large, and the production efficiency is low. Utility Model Content

[0004] In view of the shortcomings of the prior art, an integrated outlet clamp and motor are proposed, which solves the problems in the above background technology that the outlet sheath and the isolating ring are set in different processes, the production and assembly process is cumbersome, the labor input is large, and the production efficiency is low.

[0005] In order to achieve the above purpose, the utility model proposes the following technologies to achieve it:

[0006] An integrated wire outlet clamp comprises a wire outlet sheath and an isolating ring. The wire outlet sheath is provided with an isolating ring connecting belt, and the isolating ring is connected to the isolating ring connecting belt, thereby realizing the integration of the wire outlet sheath and the isolating ring.

[0007] The function of the outlet sheath is to ensure that the power line connecting the power supply and the winding is standardized, and to ensure the stability of its position, so as not to be affected by external forces and cause its position to change, thereby affecting the welding quality of the power line. The function of the isolating ring is to ensure the electrical safety after the motor is powered on. Integrating the two together makes the process assembly relatively more convenient, more efficient, and reduces the overall material cost.

[0008] Furthermore, the outlet sheath comprises two sub-outlet sheaths that can be buckled with each other, and the insulating ring connecting belt is fixedly connected to at least one sub-outlet sheath.

[0009] Furthermore, an outlet sheath connecting belt is arranged between the two sub-outlet sheaths, and the insulating ring connecting belt and the outlet sheath connecting belt are respectively arranged on both sides of the sub-outlet sheaths.

[0010] Furthermore, the isolating ring connecting belt extends to the outside of the outlet sheath, the isolating ring connecting belt is arc-shaped, and the isolating ring and the isolating ring connecting belt are softly connected.

[0011] Furthermore, the outlet sheath is clamped on the stator outlet of the stator assembly, and the insulating ring is arc-shaped, and the arc shape matches the shape of the installation groove of the stator assembly.

[0012] Furthermore, the central angle of the insulating ring is less than 360 degrees and greater than 90 degrees, so as to separate the terminal pins on the stator assembly and the end cover connected to the stator assembly.

[0013] Furthermore, a connecting portion is provided between the isolating ring and the isolating ring connecting belt to achieve a soft connection between the isolating ring and the isolating ring connecting belt. After the outlet wire sheath is installed to the stator assembly, the isolating ring can be rotated around the isolating ring connecting belt through the connecting portion to connect with the terminal pin shield.

[0014] Furthermore, the outlet sheath is provided with a card slot and a wire slot, one of the sub-outlet sheaths is provided with a positioning hole, and the other sub-outlet sheath is provided with a positioning column matching the positioning hole.

[0015] Furthermore, the clamping groove is clearance-matched with the stator assembly stopper on the stator assembly to determine the installation position of the outlet wire sheath on the stator assembly.

[0016] A motor comprises a wire outlet clamp, wherein the wire outlet clamp is the integrated wire outlet clamp as described in any one of the above items.

[0017] Compared with the prior art, the comprehensive effects brought by the utility model include:

[0018] (1) The present application integrates the outlet wire sheath and the isolating ring into one, replacing the original method of placing the outlet wire sheath and the isolating ring separately in different processes, and synchronizing with the power cord assembly incoming materials. The isolating ring placement action is cancelled in the later process, and the deflection angle of the isolating ring does not affect the assembly of the wiring harness on the stator. The end cover pressing station directly presses down along the isolating ring to ensure that there is insulating material between the terminal pin and the end cover, thereby improving production efficiency and achieving cost reduction and efficiency improvement.

[0019] (2) The present application integrates the isolating ring with the outlet wire sheath. The position of the isolating ring can be fixed and will not move after assembly to cause noise problems. The present application sets a partial annular isolating ring to protect only the three needle positions, which not only meets the insulation effect but also reduces the use of the raw materials for the isolating ring by about 2 / 3 on the original basis, thereby greatly reducing the cost of using the materials for the isolating ring.

[0027] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the utility model.

The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "top", etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0029] like Figures 1 to 6 As shown, an integrated outlet clamp includes an outlet sheath and an insulating ring 1, the outlet sheath is provided with an insulating ring connecting belt 2, the insulating ring 1 is connected to the insulating ring connecting belt 2, thereby realizing the integration of the outlet sheath and the insulating ring 1.

[0030] By arranging an isolating ring connecting belt 2 on the outlet wire sheath and connecting the isolating ring 1, the integration of the outlet wire sheath and the isolating ring 1 is realized. Compared with the existing batch production process of process models: the outlet wire sheath and the power cord are assembled into incoming materials, the employee places the outlet wire sheath at the stator outlet and then welds the power cord to the stator assembly, and places the isolating ring 1 after matching with the rotor assembly. Instead of the original separate and separate process placement method of the outlet wire sheath and the isolating ring 1, the isolating ring 1 and the power cord are assembled into incoming materials synchronously to realize the assembly of the outlet wire sheath isolating ring 1, and the action of placing the isolating ring 1 is cancelled in the later process, which is convenient for achieving cost reduction and efficiency improvement, reducing actions during process production, and thus improving production efficiency.

[0031] In the integrated outlet clamp of this embodiment, the outlet sheath includes two sub-outlet sheaths that can be buckled with each other, and the insulating ring connecting belt 2 is fixedly connected to at least one sub-outlet sheath.

[0032] Specifically, the outlet sheath includes a first outlet sheath 3 and a second outlet sheath 4 which can be interlocked. The outlet sheath is arranged to be split, which is convenient for placing and installing the connecting wire and reduces the difficulty of installation. At the same time, the interlocking structure is easy to disassemble and the position of the connecting wire can be adjusted.

[0033] Preferably, the isolating ring connecting belt 2 is connected to the two sub-outlet sheaths respectively, and the connection between the outlet sheath and the isolating ring 1 is realized while the two sub-outlet sheaths are connected, which facilitates the rapid assembly of the first outlet sheath 3 and the second outlet sheath 4.

[0034] Preferably, the isolating ring connecting belt 2 is fixedly connected to the first outlet sheath 3, so as to realize the connection between the outlet sheath and the isolating ring 1, reduce the material of the isolating ring connecting belt 2, and avoid interference when the two sub-outlet sheaths are buckled together.

[0035] In the integrated outlet clamp of this embodiment, an outlet sheath connecting belt 5 is arranged between the two sub-outlet sheaths, and the isolation ring connecting belt 2 and the outlet sheath connecting belt 5 are respectively arranged on both sides of the sub-outlet sheaths.

[0036] Specifically, the first outlet sheath 3 and the second outlet sheath 4 are connected by the outlet sheath connecting belt 5, and the first outlet sheath 3 and the second outlet sheath 4 are paired by the outlet sheath connecting belt 5, so as to avoid wasting time in finding two matching sub-outlet sheaths during assembly, and facilitate the rapid assembly of the first outlet sheath 3 and the second outlet sheath 4.

[0037] Preferably, the isolating ring connecting band 2 and the outlet sheath connecting band 5 are respectively arranged on both sides of the first outlet sheath 3. The above structure prevents the outlet sheath connecting band 5 from bending and interfering with the isolating ring connecting band 2 when the two sub-outlet sheaths are buckled together, thereby ensuring smooth assembly of the outlet sheath.

[0038] In the integrated outlet clamp of this embodiment, the isolating ring connecting belt 2 extends to the outside of the outlet sheath, and the isolating ring connecting belt 2 is arc-shaped, and the isolating ring 1 and the isolating ring connecting belt 2 are softly connected.

[0039] In order to prevent the isolation ring 1 from interfering with the stopper position of the stator assembly 6 outlet, the extension portion is designed to connect the outlet sheath with the isolation ring 1. Figure 2 As shown, the right end of the isolating ring connecting belt 2 is connected to the middle of the first outlet sheath 3, and the isolating ring connecting belt 2 is integrally formed with the first outlet sheath 3 to ensure the installation strength of the isolating ring connecting belt 2. The left end of the isolating ring connecting belt 2 extends to the outside of the outlet sheath and is connected to the isolating ring 1. The above structure avoids interference between the isolating ring 1 at the end of the isolating ring connecting belt 2 and the outlet sheath when the first outlet sheath 3 and the second outlet sheath 4 are unfolded.

[0040] Specifically, a connection portion is provided between the isolating ring 1 and the isolating ring connecting belt 2, and the isolating ring 1 can rotate with the isolating ring connecting belt 2 around the connection portion; it is set as a soft connection to improve the flexibility of the isolating ring 1, and it is convenient to adjust the isolating ring 1 during installation. After the outlet sheath is buckled and installed on the stator assembly 6, the isolating ring 1 is rotated to fit with the stator assembly 6, and the terminal pins 7 on the stator assembly 6 are shielded to ensure the safety of the electrical appliance after the motor is powered on.

[0041] Preferably, Figure 4 As shown, the isolating ring 1 is integrated with the outlet sheath through the isolating ring connecting belt 2, and the whole one-piece injection mold is realized. The isolating ring 1 and the isolating ring connecting belt 2 are at a horizontal angle of 60°. The purpose is to prevent the upper harness worker from folding the isolating ring 1 up and down to operate when assembling the power cord, which affects efficiency. The bent isolating ring 1 is automatically pressed down during the end cap pressing process, which does not affect the operation, thereby improving production efficiency.

[0042] In the integrated outlet clamp of this embodiment, the outlet sheath is clamped on the stator outlet port of the stator assembly 6, and the insulating ring 1 is arc-shaped, and the arc shape matches the shape of the installation groove of the stator assembly 6.

[0043] Specifically, the isolating ring 1 in the present application is configured as a partial annular structure. In the prior art, the motor isolating ring 1 is designed as a full circle. The purpose is to prevent the isolating ring 1 from moving after being assembled in the motor body and causing noise problems. In the present application, the isolating ring 1 is connected to the outlet wire sheath through the isolating ring connecting belt 2 to achieve the integration of the isolating ring 1 and the outlet wire sheath. The position of the isolating ring 1 can be fixed. After the outlet wire sheath is installed and fixed, the isolating ring 1 is also limited. Therefore, there will be no position movement and noise problems after assembly. Setting a partial ring shape can reduce the use of production materials and reduce production costs.

[0044] In the integrated outlet clamp of this embodiment, the central angle of the insulating ring 1 is less than 360 degrees and greater than 90 degrees, so as to separate the terminal pins 7 on the stator assembly 6 and the end cover 8 connected to the stator assembly 6.

[0045] like Figure 5 and Figure 6 As shown, the main function of the isolating ring 1 is to prevent the three-way needle from draining or contacting the rear end cover to cause electrical safety accidents, so it is only necessary to protect the three-way needle position on the stator assembly 6, that is, the 90° position in the full circle of 360°. Preferably, the isolating ring connecting belt 2 plus the front end of the isolating ring 1 reserve a small space. In the present application, the isolating ring 1 is set to be one-third of the full ring, which ensures the insulation effect while saving about 2 / 3 of the material on the basis of the full circle ring in the prior art, thereby reducing the production cost.

[0046] In the integrated outlet clamp of this embodiment, the outlet sheath is provided with a clamping slot 9 and a wire slot 10 , one of the sub-outlet sheaths is provided with a positioning hole 11 , and the other sub-outlet sheath is provided with a positioning column 12 matching the positioning hole 11 .

[0047] Preferably, the card slot 9 is matched with the stator assembly stop gap on the stator assembly 6. The card slot 9 is used to place the wire outlet clamp in a fixed position on the stator assembly 6 to determine the installation position of the wire outlet sheath on the stator assembly 6, which is convenient for employees to take and assemble and improve production efficiency; the wire slot 10 is the position where the power cord is placed, and the five power cords of the motor control board are connected through the wire slot 10 according to the standard wire sequence, thereby avoiding the power cords from being stacked in the wire outlet sheath and causing squeezing.

[0048] Specifically, a positioning hole 11 is provided on the first outlet sheath 3, and a positioning column 12 matching the positioning hole 11 is provided on the second outlet sheath 4. The positioning hole 11 and the positioning column 12 position the two sub-outlet sheaths, and the power cord is neatly placed in the outlet sheath groove 10. After the two sub-outlet sheaths are matched, the power cord and the outlet sheath are in a relative position and interference fit, so as to prevent the power cord from loosening and changing its position.

[0049] The present application also provides a motor, including the above-mentioned integrated outlet clamp, which includes all the beneficial effects of the above-mentioned integrated outlet clamp, which will not be repeated here.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0051] Although the embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
