Description

Technical Field

[0001] The utility model relates to the technical field of plastic-encapsulated motors, and in particular to a plastic-encapsulated motor with high-reliability line connection. Background Art

[0002] A plastic-encapsulated motor uses plastic encapsulation technology to integrally encapsulate the stator core, winding, etc. of the motor with engineering plastics, and can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. This kind of micro-special motor is applied in household appliances such as vacuum cleaners, range hoods, air conditioners, washing machines, and instrument fans. The research and production of plastic-encapsulated motors at home and abroad have become increasingly important, and it has good prospects because of a series of advantages that metal-cased motors do not have. The existing plastic-encapsulated motors mainly consist of a housing, a stator, a rotor, and wire connections. The stator is fixedly connected inside the housing, and the rotor is rotatably connected inside the housing, so that the wires are electrically connected to the stator and the rotor. When the wires are energized, the rotation of the rotor can be achieved.

[0003] Although the above scheme can realize the operation of the plastic-encapsulated motor, there are still the following problems: Since the main function of the wires is to conduct electricity and they are electrically connected to the stator and the rotor, when the motor is being carried or moved, if the wires are pulled by an external force, it is very easy for the connections between the wires and the stator and the rotor to become disconnected, thereby reducing the line connection between the wires and the stator and the rotor, and causing the stator and the rotor to malfunction. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a plastic-encapsulated motor with high-reliability line connection, which can reduce the disconnection of the connection between the wires and the stator and the rotor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A plastic-encapsulated motor with high-reliability line connection includes: a housing, a stator-rotor assembly disposed inside the housing, and wires disposed on the housing and electrically connected to the stator-rotor assembly.

[0007] On the side walls of the housing on both sides of the wires, there are slidably connected clamping frames arranged oppositely. A locking member is provided on the clamping frames, and the locking member can fix the clamping frames on the housing.

[0008] Both ends of the clamping frame are inclined towards the wires.

[0009] A clamping block is fixedly connected to the clamping frame. The clamping block is arc-shaped and can be attached to the wires.

[0010] Friction grooves are formed on the two clamping blocks, and the friction grooves are arranged oppositely.

[0011] Preferably, a plurality of clamping rods arranged oppositely to the electric wire are fixedly connected to the inner wall of the clamping frame, and fixing blocks are fixedly connected to the clamping rods.

[0012] Preferably, a plurality of intersecting friction strips are fixedly connected to the fixing block, and the friction strips can be attached to the electric wire.

[0013] Preferably, a positioning rod is fixedly connected to one of the clamping frames, and a positioning hole for the positioning rod to enter is formed through the other clamping frame.

[0014] Preferably, the locking member includes a sliding block slidably connected to the outer shell and fixedly connected to the clamping frame, and a fixing rod slidably connected to the outer shell. A plurality of fixing holes for the fixing rod to enter are formed in the outer shell.

[0015] Preferably, a moving rod is fixedly connected to the outer shell, and the moving rod is slidably connected to the sliding block.

[0016] Preferably, rubber blocks are fixedly connected to the clamping blocks, and the rubber blocks can be attached to the electric wire.

[0017] Advantages of the present utility model: Compared with the prior art, in the present utility model, the relatively sliding clamping frames are arranged on the outer shell, the clamping frames drive the clamping blocks to be attached to the electric wire, and then the locking member locks the clamping frames to the outer shell, so as to fix the electric wire, further improving the fixing effect of the electric wire. By arranging fixing points on the electric wire, the two ends of the electric wire close to the stator and the rotor are fixed on the outer shell, so that the situation of wire disconnection during the pulling process of the electric wire can be reduced, and further the fixing reliability of the connection between the electric wire and the stator is increased.

Detailed implementation mode

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed implementation mode:

[0024] In the description of this specification, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0025] As Figures 1 to 4 , a plastic-sealed motor with highly reliable line connection includes: an outer shell 1, a stator-rotor component 2 arranged inside the outer shell 1, and an electric wire 3 arranged on the outer shell 1 and electrically connected to the stator-rotor component 2. Among them, the stator-rotor component 2 in the present utility model is mainly composed of a stator one 18 and a rotor one 19 connected. The stator one 18 is fixedly connected to the outer shell 1, while the rotor 19 is rotatably connected inside the outer shell 1, and the output shaft of the rotor 19 extends outside the outer shell 1 and is connected to the stator and the electric wire 3 of the rotor 19 through the electric wire 3, so as to achieve the operation of the rotor 19;

[0026] The plastic-sealed motor in the present utility model further includes: a clamping frame 4, a locking component 5, and a clamping block 6 connected;

[0027] There are two clamping frames 4, and they are slidably connected to the outer shell 1 relatively. By moving the clamping frame 4, the clamping block 6 fixedly connected to the clamping frame 4 can be driven to move, so that the clamping block 6 is in contact with the electric wire 3, thereby achieving the fixation of the electric wire 3. When the electric wire 3 is fixed, the locking component 5 fixedly connected to the clamping block 6 is connected to the outer shell 1, so as to achieve the fixation of the clamping frame 4;

[0028] It is worth mentioning that both ends of the clamping frame 4 are inclined. Through the inclined clamping frame 4, it is convenient to better make the clamping block 6 in contact with the electric wire 3. A number of friction strips 10 are provided on the clamping block 6, thereby increasing the friction between the electric wire 3 and the clamping block 6, and thus increasing the fixing effect of the electric wire 3.

[0029] Specifically, a number of clamping rods 8 are fixedly connected to the inner wall of the clamping frame 4 and are arranged opposite to the electric wire 3. One end of the clamping rod 8 is fixedly connected to a fixing block 9, so that the fixing block 9 is in contact with the electric wire 3, thereby achieving the fixation of the electric wire 3 and further improving the fixing effect of the electric wire 3.

[0030] Specifically, a number of friction strips 10 are fixedly connected to the fixing block 9 and are arranged in a staggered manner. By making the friction strips 10 in contact with the electric wire 3, the friction force between the fixing block 9 and the electric wire 3 is increased, and the fixing effect between the electric wire 3 and the fixing block 9 is further improved.

[0031] Specifically, since a positioning rod 11 is fixedly connected to one of the clamping frames 4, and a positioning hole 12 for the positioning rod 11 to enter is penetrated through the other clamping frame 4, by making the positioning rod 11 enter the positioning hole 12, the positioning effect between the two clamping frames 4 is increased.

[0032] Specifically, since the locking member 5 includes a sliding block 13 slidably connected to the housing 1 and fixedly connected to the clamping frame 4 and a fixing rod 14 slidably connected to the housing 1, and a number of fixing holes 15 for the fixing rod 14 to enter are provided on the housing 1, by inserting the fixing rod 14 into the fixing holes 15, the fixing of the sliding block 13 is achieved. It is worth mentioning that the fixing rod 14 is provided with an external thread, and the fixing hole 15 is provided with an internal thread. Through the thread connection between the internal thread and the external thread, the fixing rod 14 can be fixed.

[0033] Specifically, a moving rod 16 is fixedly connected to the housing 1. By making the moving rod 16 slidably connected to the sliding block 13, the situation that the sliding block 13 rotates can be avoided.

[0034] Specifically, a rubber block 17 is fixedly connected to the clamping block 6. By making the rubber block 17 in contact with the electric wire 3, the fixation of the rubber block 17 can be achieved.

[0035] Principle of the present utility model: The movement of the clamping frame 4 drives the movement of the clamping block 6, and the clamping block 6 is moved to be in contact with the electric wire 3, thereby achieving the fixation of the electric wire 3. When the electric wire 3 is fixed, the locking member 5 fixes the clamping frame 4 and the housing 1, thereby achieving the fixation of the clamping frame 4. Friction grooves 7 are staggeredly provided on the clamping block 6, thereby increasing the friction force between the electric wire 3 and the clamping block 6, and indirectly increasing the fixing effect between the clamping block 6 and the electric wire 3.

[0036] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
