TECHNICAL FIELD

[0001] The utility model relates to motor technical field, concretely is a kind of motor of improving waterproof performance. BACKGROUND

[0002] In prior art, there are many deficiencies in the structural design and sealing performance of motor. The traditional motor mainly relies on rivet joint mode to connect between components, which can fix each component of motor to some extent, but there are small gaps in rivet fitting, which become potential channels for water and other impurities to enter the inside of motor.

[0003] Especially in some terminal use environments, such as outdoor, humid or underwater scenes, motor will inevitably contact water. Once water seeps into the inside of motor through these gaps, it will cause oxidation and rust to metal parts of motor. The oxidation and rust not only reduce the mechanical and electrical properties of metal parts, but also lead to instability and failure of motor performance. More seriously, if water seeps into the terminal of motor, it will also cause oxidation of terminal, leading to poor contact of motor and affecting normal operation of motor. SUMMARY

[0004] In view of the deficiencies of prior art, the utility model provides a kind of motor of improving waterproof performance, solves the problems raised in the above background art.

[0005] To achieve the above object, the utility model is realized by the following technical scheme: a kind of motor of improving waterproof performance, including motor main body, wire and terminal, wire is connected between motor main body and terminal, further comprising:

[0006] Waterproof sheath, the waterproof sheath is wrapped and set in the outside of motor main body, for sealing the shell of motor main body and the connecting place between it and front, rear end cover;

[0007] Sealing rubber ring, the sealing rubber ring is sleeved in the outside of terminal insertion place, to improve the sealing performance of connecting place.

[0008] Further, the waterproof sheath is set as heat shrink sleeve or elastic rubber sleeve.

[0009] Further, the end of waterproof sheath is integrally connected with outlet tube communicated with its inside, for wire to pass out.

[0010] Further, the insertion place of terminal is provided with reserved slot outside, and the sealing rubber ring is clamped in reserved slot after being sleeved.

[0011] Further, the outside of sealing rubber ring is integrally connected with several stepped protrusions.

[0012] Further, the sealing rubber ring and the stepped protrusion are shaped to match the insertion part of the terminal.

[0013] The utility model provides a motor of waterproof performance is improved.

[0014] Beneficial effects:

[0015] The motor of waterproof performance is improved, by adopting waterproof sheath and sealing rubber ring and other innovative design, effectively solve the waterproof performance problem of the existing motor because of the connecting gap, significantly improve the sealing property and waterproof performance of motor, thereby effectively avoid the oxidation of the internal metal parts of motor and the terminal contact failure and other faults, ensure the stable operation of motor in the humid or underwater and other harsh environment, prolong the service life of motor.

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4The utility model provides a technical scheme: a motor of improving waterproof performance, mainly by motor main body 1, waterproof sheath 2, wire 3, terminal 4 and sealing rubber ring 5 are formed, wherein, the specific structure and working principle of motor main body 1 are prior art, do not detail here, waterproof sheath 2 is wrapped and is arranged in the outside of motor main body 1, can seal the shell of motor main body 1 and the connecting place between front and rear end covers, waterproof sheath 2 is set to heat shrink sleeve, wire 3 is connected between motor main body 1 and terminal 4, plays the role of communication and power supply, sealing rubber ring 5 is set up in the outside of terminal 4 insertion joint,

[0024] The end of waterproof sheath 2 is integrally connected with an outlet pipe 21, waterproof sheath 2 and outlet pipe 21 are communicated, outlet pipe 21 corresponds to the position where motor main body 1 and wire 3 are connected, so that wire 3 can pass out from the inside of waterproof sheath 2 after being wrapped by waterproof sheath 2 and be connected with terminal 4;

[0025] In the above technical scheme, after the waterproof sheath 2 made of heat shrink sleeve material is wrapped outside the motor main body 1, the sealing performance of the motor main body 1 can be greatly improved, and thus the waterproof performance is improved. In addition, the sealing rubber ring 5 is sleeved outside the terminal 4 insertion joint, which can improve the sealing performance of the connection between the terminals. Similarly, the waterproof performance at this position is also improved.

[0026] In addition, a reserved groove 41 is formed outside the terminal 4 insertion joint, the sealing rubber ring 5 is clamped in the reserved groove 41 after being sleeved, and a plurality of stepped protrusions 51 are integrally connected to the outside of the sealing rubber ring 5. On the one hand, the sealing rubber ring 5 is not easy to fall off after being sleeved, and on the other hand, the plurality of stepped protrusions 51 can further improve the sealing effect when the terminals are inserted. The shapes of the sealing rubber ring 5 and the stepped protrusions 51 are both rectangular structures, so as to be compatible with the insertion joint of the terminal 4 which is also a rectangular structure.

[0027] Embodiment 2

[0028] The utility model provides a technical scheme: a motor of improving waterproof performance, compared with the motor of embodiment 1, the difference of the motor of this embodiment lies in: the waterproof sheath 2 in the motor of this embodiment is set as an elastic sleeve. When the waterproof sheath 2 is assembled outside the motor main body 1, it can be directly sleeved outside the motor main body 1. After being sleeved, the waterproof sheath 2 tightly adheres to and wraps the outside of the motor main body 1 due to its own elastic property. In the motor of embodiment 1, the heat shrink sleeve needs to be placed in a tunnel furnace for baking after being sleeved, so that the heat shrink sleeve shrinks after being heated, thereby tightly adhering to and wrapping the outside of the motor main body 1.

[0029] In summary, the waterproof sheath 2 used in Examples 1 and 2 is different in material and corresponding assembly process, but the final effect can greatly improve the waterproof performance of the motor body 1, and the waterproof effect is improved compared with the conventional motor, and the service life in a humid or splashing water environment is prolonged.
