Technical Field
The utility model relates to a reluctance type resolver technical field specifically is a waterproof construction for reluctance type resolver.
Background
The existing new energy automobile motor requires the waterproof grade of IP67 forcibly, the reluctance type rotary transformer is used as a key position sensor in the automobile motor, when the reluctance type rotary transformer is installed at the tail of the motor and connected with a wire, because the outgoing line of the reluctance type rotary transformer is composed of a plurality of electronic wires, when the electronic wires are installed in the commonly used waterproof joints in the existing market, the waterproof joints cannot completely lock and seal the electronic wires due to gaps among the electronic wires, the waterproof performance is affected, and at the moment, liquid such as water, oil and the like can be immersed in the reluctance type rotary transformer along the gaps between the waterproof joints and the electronic wires and between the electronic wires, so that the reluctance type rotary transformer has functional failures such as signal confusion, rusting and the like.
Disclosure of Invention
To the above problem, the utility model provides a waterproof construction for magnetic resistance formula resolver, it has better leakproofness, can improve waterproof performance greatly to increase magnetic resistance formula resolver's operational reliability and life.
The technical scheme is as follows: the rotary transformer comprises a rotary transformer main body arranged in a motor body, wherein a leading-out wire of the rotary transformer main body penetrates out of the motor body and is locked through a waterproof connector, the waterproof connector comprises a waterproof connector body and a packing head which are connected, the waterproof connector body is locked on the motor body, and the leading-out wire penetrates through the waterproof connector body and the packing head, and is characterized in that: the waterproof connector is characterized in that a clamping ring is arranged between the waterproof connector body and the tightening head, the clamping ring is of a solid structure, the clamping ring is pressed in the waterproof connector body, and a through hole in interference fit with the outgoing line is formed in the clamping ring.
It is further characterized in that:
the outer diameter of one end of the clamping ring is smaller than that of the other end of the clamping ring, the small-diameter end part of the clamping ring is pressed in the waterproof connector body, and a sealing ring is arranged between the waterproof connector body and the motor body;
the small-diameter end part of the clamping ring is trapezoidal, the through hole is formed in the trapezoidal end part of the clamping ring, and the large-diameter end part of the clamping ring is provided with a groove communicated with the through hole;
the number of the through holes is 6, and the diameter of each through hole is phi 1.3 mm.
The beneficial effects of the utility model are that, the tight circle of clamp that sets up between the water joint body and the compelling head is solid construction, and open on the tight circle of clamp have with lead-out wire interference fit's through-hole, then the lead-out wire is worn out the back from the motor body, passes the water joint body, presss from both sides tight circle, then screws up and compels tight head, can make the rotary transformer main part seal completely inside the motor body through pressing from both sides tight circle to rotary transformer's waterproof ability has been improved greatly, greatly increased rotary transformer's life and operational reliability.
