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.

摘要： The present invention discloses an electrically conductive module of a solar cell terminal box. The electrically conductive module comprises an insulation body, conducting strips and a diode chip, wherein there are two and only two conducting strips. The two conducting strips are electrically connected through the diode chip. The diode chip is located inside the insulation body. Each of the two conducting strips is provided with a through hole. The two side edges, which are fixed with the conducting strips, of the insulation body overlap with the through holes. A connection region between the insulation body and each of the conducting strips is only a region between the end portion of the corresponding through hole and the edge of the conducting strip. A part of each through hole is located inside the insulation body, and the remaining part of the through hole is located outside the insulation body and forms an enclosed busbar welding hole together with two side edges of the insulation body. The connection regions between the insulation body and the conducting strips are just the four smaller regions between the end portions of the through holes and the edges of the conducting strips, which can effectively prevent the insulation body from suffering the acting force exerted by the external force through the conducting strips, and avoid the phenomenon that the body is damaged or excessively stressed, etc.

摘要： The present invention discloses a junction box for a solar cell. The junction box includes a box body, wherein the box body is provided with a plurality of conducting pieces for connecting solar cell pieces; two adjacent conducting pieces are connected by a diode; the conducting pieces at both ends are connected to the outside parts via a guide line respectively; and the forward dissipation power of the diode in the middle is less than that of the diodes at both sides. According to the invention, the diode with lower forward dissipation power is employed in parts where the temperature rise is easily produced to reduce the temperature rise; while the diode with higher forward dissipation power is employed in parts where the temperature rise is not easily produced to control cost.
