Embodiment Construction

[0014] The present invention will be further described below in conjunction with the drawings.

[0015] As shown in the figure, in order to solve the above technical problems, the wiring terminal dedicated for the photovoltaic junction box circuit board of the present invention includes a housing 1, a conductor 2, a spring sheet 3, a cover plate, and a wire inlet and a wire are provided on the housing 1. The housing 1 can be inserted into the housing 1 through the wire inlet, and the housing 1 and the cover plate are connected together by fasteners. The conductor 2 is a planar member with sides 21 on both sides. The lower end of the conductor 2 is provided with an extension piece 22 for connecting to other conductors. The conductor 2 is fixedly arranged on the inner wall of the housing 1 or by other means. In the housing 1, a spring leaf 3 is arranged in the housing 1. One end of the spring leaf 3 is fixed on the inner surface of the housing 1 by a pin or other means, and the oth...

Abstract

The invention provides a wire connecting terminal special for a photovoltaic wire connecting box circuit board. The wire connecting terminal comprises a shell, an electric conductor arranged in the shell and a spring piece, wherein a wire inlet is arranged on the shell; the spring piece is arranged in the shell; one end of the spring piece is fixed on the inner surface of the shell, while the other end is abutted against the side edge of the electric conductor and in elastic contact with a lead inserted in the shell; the end of the spring piece in contact with the lead comprises a first elastic piece and a second elastic piece which are connected in a V shape; and the tail end of the first elastic piece is provided with a plurality of convex teeth. Because the tail end of the second elastic piece is provided with a plurality of convex teeth, when the spring piece is in the elastic contact with the lead, friction force between the spring piece and the lead is increased, thus the lead isnot easy to pull out after being inserted in the shell. The locking capacity of the wire connecting terminal is greatly improved and the connection between the lead and the electric conductor is morereliable.

Description

Technical field [0001] The invention relates to a wiring terminal, particularly a wiring terminal dedicated to a photovoltaic junction box circuit board, and belongs to the technical field of wire connection devices. Background technique [0002] A terminal is a connecting device used to realize electrical connection. Due to the convenient connection of the terminal blocks, they are widely used in various power places. Recently, with the development of the photovoltaic industry, terminal blocks are used for junction boxes. The built-in bypass diodes of the first generation of photovoltaic junction boxes are mostly plug-in types. When the diodes are inserted into the surface of the metal parts, contact resistance will be generated. When the photovoltaic modules are accidentally blocked, the built-in bypass diodes will pass a large current. Generate power loss, the surface temperature will rise sharply, coupled with the power consumption generated by the contact resistance of the...
