Device for sensing wheel speed

A device for sensing wheel speed, comprising:

• a wheel speed sensor assembly having a sensor body in which a first sensor element and a second sensor element configured to sense a wheel speed of a vehicle which are embedded, and first and second lead frames electrically connected to the first sensor element and extending to an outside of the sensor body, and third and fourth lead frames electrically connected to the second sensor element and extending to the outside of the sensor body;
• a first cable having a first conductive wire electrically connected to the first lead frame and a first sheath covering the first conductive wire;
• a second cable having a second conductive wire electrically connected to the second lead frame and a second sheath covering the second conductive wire;
• a third cable having a third conductive wire electrically connected to the third lead frame and a third sheath covering the third conductive wire;
• a fourth cable having a fourth conductive wire electrically connected to the fourth lead frame and a fourth sheath covering the fourth conductive wire;
• a first connector covering at least a part of the first lead frame and one end of the first conductive wire that is exposed out of one end of the first sheath of the first cable and is disposed to contact the first lead frame, and fixedly supporting the first lead frame and the first conductive wire such that the first lead frame and the first conductive wire are fixed to be contacted with each other;
• a second connector covering at least a part of the second lead frame and one end of the second conductive wire that is exposed out of one end of the second sheath of the second cable and is disposed to contact the second lead frame, and fixedly supporting the second lead frame and the second conductive wire such that the second lead frame and the second conductive wire are fixed to be contacted with each other;
• a third connector covering at least a part of the third lead frame and one end of the third conductive wire that is exposed out of one end of the third sheath of the third cable and is disposed to contact the third lead frame, and fixedly supporting the third lead frame and the third conductive wire such that the third lead frame and the third conductive wire are fixed to be contacted with each other;
• a fourth connector covering at least a part of the fourth lead frame and one end of the fourth conductive wire that is exposed out of one end of the fourth sheath of the fourth cable and is disposed to contact the fourth lead frame, and fixedly supporting the fourth lead frame and the fourth conductive wire such that the fourth lead frame and the fourth conductive wire are fixed to be contacted with each other;
• and
• a cable holder having a connection part having first to fourth through holes, wherein the first to fourth lead frames are disposed in first ends of the first to fourth through holes of the connection part, respectively, the first to fourth conductive wires are disposed in second ends of the first to fourth through holes of the connection part, respectively.
