Detailed Description

The present utility model is further illustrated in the following drawings and detailed description, which are to be understood as being merely illustrative of the utility model and not limiting the scope of the utility model.

As shown in fig. 1, 2 and 3, a terminal for use in a photovoltaic connector of a photovoltaic module includes a terminal tail section for receiving and expanding the tail section, and a terminal middle section for receiving the photovoltaic connector; the outer side end face of the terminal tail section 9 is sleeved with a clamp spring 2, the terminal tail section 9 and the terminal middle section 4 are of an integrated connection structure, the outer diameter of the terminal middle section 4 is larger than that of the terminal tail section 9, the top of the terminal middle section 4 is integrally connected with a terminal head section 5, and the top of the terminal head section 5 is connected with a crimping fin 8 through a neck section; the utility model divides the whole terminal into three sections, namely a terminal head section 5, a terminal middle section 4 and a terminal tail section 9. The external diameter of the terminal tail section 9 is smaller than that of the terminal middle section 4, so that the gap between the terminal tail section and the terminal middle section can be filled after the clamp spring 2 is sleeved in the later stage, and an uneven mounting plane is avoided in the later stage mounting process. The terminal middle section 4 is used as a whole wrapping structure of the terminal, and the self-mounting structure of the terminal middle section is relatively closed. The structure of the terminal first section 5 is relatively open, a semi-wrapping semi-exposed structure is adopted, and meanwhile, the installation structure of the crimping fins 8 and the crimping process of the subsequent cable is adopted.

Terminal tail section 9, terminal middle section 4 and terminal first section 5 integral type constitute the terminal, the terminal remains along terminal middle section 4 and is formed by special-shaped concatenation tip 10, and terminal left and right sides both ends are through the crooked butt joint of special-shaped concatenation tip 10. In order to enable the whole terminal to form an integrally formed structure in the process of processing and production, the terminal is provided with a winding structure, the winding head and tail ends are combined along the special-shaped splicing end part 10, the special-shaped splicing end part 10 is used as a buckling structure, and the phenomenon that the whole terminal is separated from a connector due to the fact that a smooth straight line closing gap is broken in a subsequent installation or extrusion and expansion environment is avoided.

As shown in fig. 1, 2 and 3, the tail of the terminal middle section 4 and the terminal tail section 9 are provided with four groups of expansion grooves 3, and the four groups of expansion grooves 3 are uniformly distributed on the outer wall of the terminal tail section 9 communicated with the tail of the terminal middle section 4. The arrangement of the expansion tank 3 can promote the installation convenience. During installation, the terminal tail sections 9 may be extended outwardly along the expansion slots 3 to achieve the installation effect. After the installation is completed, the clamp spring 2 is installed; the bundling structure of the snap spring 2 can adaptively limit the terminal tail section 9 to stretch outwards.

As shown in fig. 1, 2 and 3, a flash 1 is reserved at the tail end of the terminal tail section 9, the flash 1 is in lifting contact with the bottom of the clamp spring 2, the clamp spring 2 is of an integrated curled structure, and an opening which is obliquely formed between the head end and the tail end of the clamp spring 2 is reserved. The flash 1 can support the clamp spring 2, so that the clamp spring 2 is prevented from sliding off.
