摘要： The present invention discloses a connector for a photovoltaic cell. The connector comprises a conductive portion and an insulating portion, wherein the conductive portion is wrapped with the insulating portion; the conductive portion is composed of a conductor and a cable line which are riveted with each other, and a retaining ring is arranged on the outer circumferential surface of the conductor; the insulating portion comprises a shell body, a basket-shaped fastener and a front sleeve; a first inner step surface and a second inner step surface are arranged in an inner cavity of the shell body; the front sleeve has an annular head part which sleeves the conductor; a first outer step surface is arranged at a tail part of the front sleeve, and props against the first inner step surface; the inner diameter of the head part of the front sleeve is larger than the outer diameter of the conductor and less than the outer diameter of the retaining ring. According to the connector disclosed by the present invention, the front sleeve for bearing a stress generated by the retaining ring during a forward extrusion process of the conductor is increased, such that the risks such as cracks originally appearing on the shell body and the like are transferred, and the service life of the whole connector is prolonged.
