Compressor for vehicle
View Patent ↗Disclosed is a motor-driven compressor for a vehicle adapted to fix a connector of an electric motor for a vehicle compressor. The compressor for a vehicle includes a rotor configured be rotated by an electromagnetic force generated when a current flow through a coil, a stator having at least one connector fixing slot, and a connector having a body fixed to the connector fixing slot.
1. A compressor for a vehicle comprising:
an electric motor including:
a rotor configured to be rotated by an electromagnetic force generated while a current is flowing through coils;
a stator having a cylindrical shape formed by a plurality of stacked plates, surrounding an outer periphery of the rotor and having a plurality of winding slots formed on an inner peripheral surface thereof to extend in parallel to a rotary shaft of the rotor, the coils being wound through the winding slots;
a connector configured to fix a plurality of terminals formed at a tip end of the coils wound on the stator and having a body fixed to the stator, wherein at least one connector fixing slot extending in a direction parallel to the rotary axis is formed on an outer peripheral surface of the stator, and the connector has at least one fixing boss formed integrally with the connector and extending from the connector to be inserted into the connector fixing slots, and wherein the connector fixing slot extends along an entire length of the stator in a direction parallel to the rotary axis of the stator; and,
a housing body configured to receive the connector, wherein a pocket is formed at one side of a partition wall opposite to an opened end of the housing body, and the pocket has an opening in which the connector body is positioned and a boss formed at a circumference of the opening to protrude toward an outside, wherein a length of the opening of the pocket is obtained by subtracting a length between an end turn and a bottom end of the housing body from a length of the connector body.
2. The compressor for a vehicle of claim 1 , further comprising:
a terminal connector coupled to the boss of the pocket,
wherein the terminal connector has a terminal connecting pin inserted into a terminal hole and a sealing portion for sealing the opening.
3. The compressor for a vehicle of claim 1 , wherein a plurality of terminal holes to which the terminals are fixed are formed in the connector.
4. The compressor for a vehicle of claim 1 , wherein, when the fixing boss is inserted into and fixed to the connector fixing slot, the connector extends by a height higher than a height of an end turn formed by the coils wound through the winding slots and exposed to the outside of the stator from the stator.
5. The compressor for a vehicle of claim 4 , wherein the connector has an end turn positioning portion formed by withdrawing a portion of the body to prevent interference of the end turn.
6. The compressor for a vehicle of claim 1 , wherein, when the fixing boss is inserted into and fixed to the connector fixing slot, the connector extends by a height higher than a height of an end turn formed by the coils wound through the winding slots and exposed to the outside of the stator from the stator.
7. The compressor for a vehicle of claim 6 , wherein the connector has an end turn positioning portion formed by withdrawing a portion of the body to prevent interference of the end turn.
