Said invention can combine the grounding terminal and power supply connector together and form a composite power supply connector.
Description
Technical field
The present invention relates to a kind of motor, particularly relate to a kind of composite power supply connector for motor.
Background technology
As everyone knows, motor is a kind of machine that converts electric energy to kinetic energy.It is dissimilar that motor can be divided into rotary-type motor and reciprocating motion type motor etc.Rotary-type motor is meant to convert electric energy to and revolves the motor that energy is rotated in motion; The sports type motor is meant the motor that converts electric energy to rectilinear motion kinetic energy toward returning.
Motor is commonly used on nearly all household electrical appliance as power source, for example, on the household electrical appliance such as refrigerator, air conditioner, washing machine, forced draft fan and dust catcher motor is installed all.
Fig. 1 shows the internal structure cutaway view of the common motor of prior art.Fig. 2 shows the schematic diagram of the grounded terminal combined structure of motor as shown in Figure 1.
As depicted in figs. 1 and 2, above-mentioned motor comprises: casing 10, the stator 13 that is arranged on casing 10 inside, rotor 15, rotating shaft 16, bearing 17, power connector 20 and earth terminal 30.Stator 13 is made up of lamination unshakable in one's determination 12 and the coil 11 that is wrapped on the lamination iron core 12; Rotor 15 is positioned at the central authorities in stator 13 space that surrounds, and rotor 15 is equipped with rotating shaft 16 and bearing 17; Power connector 20 is made up of terminal shell 21 and power supply terminal 22, and terminal shell 21 is installed on the outer peripheral face of casing 10, and an end of power supply terminal 22 is connected with coil 17, and the other end stretches in the above-mentioned terminal shell 21; Earth terminal 30 comprises: earth connection 31, connecting ring 32 and bolt 33; Connecting ring 32 is connected with an end of earth connection 31, and the other end ground connection of earth connection 31 is fixed on connecting ring 32 on the outer peripheral face of said machine casing 10 by bolt 33.
The course of work of above-mentioned common motor is as follows: the attaching plug 23 of power supply is inserted in the power connector 20, and after the energized, under the interaction of stator 13 and rotor 15, rotor 15 begins rotation.
In motor operation course, static on casing 10 and dangerous voltage just import the earth by earth connection 31, play the effect of ground protection.
But, the grounded terminal combined structure of above-mentioned common motor has following shortcoming: because above-mentioned grounded terminal combined structure and power connector 20 are independent respectively settings, and grounded terminal combined structure itself comprises a plurality of parts such as earth connection 31, connecting ring 32 and bolt 33 again, complex structure, assembling wastes time and energy, inconvenient operation.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of above-mentioned grounded terminal combined structure, and a kind of composite power supply connector for motor that earth terminal and power supply power supply terminal are combined as a whole is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: composite power supply connector for motor of the present invention comprises: terminal shell, power supply terminal, earth terminal and bolt; Described terminal shell is installed on the outer peripheral face of said machine casing; One end of described power supply terminal is connected with the terminals of stator coil, and the other end stretches into described terminal shell; Described earth terminal is " Z " shape, the one end is a stator with holes, and on an outer peripheral face that is bolted to said machine casing, its other end is a ground terminal blade, ground terminal blade stretches into described terminal shell, with the power supply terminal keeping parallelism.
The invention has the beneficial effects as follows: earth terminal and power connector are combined together to form a composite power supply connector, simple in structure, easy to assembly, make and assembly cost thereby reduce.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figure 3 and Figure 4, composite power supply connector for motor 120 of the present invention is arranged on the outer peripheral face of casing 10, comprising: terminal shell 121, power supply terminal 122, earth terminal 124 and bolt 125; Described terminal shell 121 is installed on the outer peripheral face of said machine casing 10; One end of described power supply terminal 122 is connected with the terminals of stator coil, and the other end stretches into described terminal shell 121; Described earth terminal is " Z " shape, the one end is a stator 124a with holes, be fixed on the outer peripheral face of said machine casing 10 by a bolt 125, its other end is a ground terminal blade 124b, ground terminal blade 124b stretches into described terminal shell 121, with power supply terminal 122 keeping parallelisms.
The operation principle of above-mentioned composite power supply connector for motor is: attaching plug 126 is inserted in the composite power supply connector 120, and after the energized, motor just brings into operation.In addition, because ground terminal blade 124b also is positioned at terminal shell 121, behind the insertion attaching plug 126; ground terminal blade 124b is connected with the earth terminal of attaching plug 126; casing is communicated with the earth, static on the casing and dangerous voltage are imported the earth, play the effect of ground protection.
Because the present invention is combined together to form a composite power supply connector with earth terminal and power connector, and is simple in structure, easy to assembly, make and assembly cost thereby reduce.
