Technical Field

[0001] The utility model relates to the technical field of photovoltaic connector accessories, in particular to an integrated photovoltaic connector combined socket. Background Art

[0002] Photovoltaic connectors (also known as MC4 connectors; although MC4 is a specific brand name, it has become a generic term for this type of connector) are primarily used for series or parallel connections between solar panels, as well as connections between panels and inverters. The basic structure of a photovoltaic connector typically includes a housing, metal terminals, and sealing rings.

[0003] At present, the metal terminals of photovoltaic connectors are composed of a basic structural combination of a metal terminal body, a cable crimping joint, a spring and a drum spring. The drum spring needs to be installed using an automatic machine during the processing process. The drum spring is easily deformed during the installation process and when the metal terminal is used, which can easily affect the pressure exerted by the drum spring on the pin, resulting in poor contact, poor resistance and even heat generation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated combined socket of a photovoltaic connector to solve the problem of poor contact caused by the easy deformation of the metal terminal drum spring proposed in the above background art.

[0007] Preferably, both outer walls of the pressure sleeve are provided with clamping blocks, one side of the pressure sleeve is provided with a connector, and both sides of the pressure sleeve are respectively clamped with the metal terminal body and the connector.

[0008] Preferably, the outer walls of the metal terminal body and the cable crimping joint are respectively fixedly connected with a second limiting sleeve and a first limiting sleeve, and the first limiting sleeve and the second limiting sleeve are distributed in left and right mirror images with respect to the bisector of the spring sleeve.

[0009] Preferably, the outer walls of the first and second limiting sleeves are both oblique hook structures, the inner wall of the elastic sleeve is provided with a slot, and the oblique hooks on the outer walls of the first and second limiting sleeves match the slot structures on the inner wall of the elastic sleeve.

[0010] Preferably, a through hole is provided on the outer wall of the elastic sleeve, and the through hole corresponds to the position of the oblique hook of the first limiting sleeve.

[0011] Preferably, the first elastic piece, the second elastic piece and the supporting piece are all distributed in a circular shape with equal intervals around the inner side of the pressurizing sleeve.

[0012] Preferably, the support sheet has a wavy bending structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) This device can improve the pressurizing performance of the pressurizing component, while avoiding deformation of the pressurizing component, ensuring close contact between the pressurizing component and the pin when pressurizing to avoid poor contact.

[0015] (2) This device provides a first spring sheet and a second spring sheet with an inwardly recessed arc structure on the inner side of the pressurizing sleeve. The arc-shaped convex parts of the first spring sheet and the second spring sheet can apply pressure to the plug pin by utilizing the characteristics of their shape. At the same time, a support sheet with a wavy bending structure is provided between the first spring sheet and the second spring sheet to support and pressurize the second spring sheet, thereby preventing the second spring sheet from being easily deformed and facilitating the separation of the second spring sheet from the plug-in.

[0016] (3) This device fixes the first limiting sleeve and the second limiting sleeve on the outer wall of the metal terminal body, and sets oblique hooks on the outer walls of the first limiting sleeve and the second limiting sleeve. When the spring sleeve is set on the outer walls of the first limiting sleeve and the second limiting sleeve, it can be snapped in, thereby avoiding the phenomenon of the spring sleeve and the metal terminal body loosening and falling off.
