Description

Technical Field

[0001] The utility model relates to the technical field of connector structures, in particular to a photovoltaic cable connector. Background Art

[0002] Photovoltaic cable connector is a device used to connect photovoltaic cables. Its function is to ensure reliable and safe cable connection in photovoltaic systems. It is composed of a metal inner core and an outer shell. Photovoltaic cable connector is designed as a pair of male and female heads. The connection between the two parts is achieved by mutual insertion of the male and female heads, realizing "plug and play";

[0003] The current connectors are installed by snap-fitting and slotting, which is easy to assemble and install on site. However, we found that the photovoltaic cable connectors still have several defects:

[0004] 1. Although the connection part is made of hard plastic (PC / PA), the structural design of the buckle and the slot results in insufficient structural stability of the connector connection. The plug-in and unplugging for a long time will cause breakage and damage. The cable terminals (also divided into male and female heads) and the connectors are generally sealed with glue (to ensure waterproofing), which causes damage to the entire cable and a short service life.

[0005] 2. Based on 1, although the cable terminals (also divided into male and female) and connectors are generally sealed with glue (to ensure waterproofing), the male and female connectors are connected, and the structure is relatively simple. Although it has a certain waterproof effect, the waterproof and moisture-proof effect is still unsatisfactory. In a humid or damp environment for a long time, the life span is greatly reduced;

[0006] In view of the above two defects, we propose a photovoltaic cable connector to solve the problems that the cable connector is easily damaged and has poor moisture and waterproof properties, thereby improving the overall service life of the photovoltaic cable connector and the cable.

[0009] Furthermore, the threaded portions on the peripheries of the connecting socket and the plug socket fit together and can be used in conjunction with each other when the connecting socket and the plug socket are plugged in.

[0010] Furthermore, an inner convex ring that contacts the plug connector is provided in the connection seat for fitting with the plug connector, and a rubber gasket is provided at the position corresponding to the inner convex ring and the plug connector.

[0011] Furthermore, the sealing structure comprises a sealing ring, and a plurality of the sealing rings are provided and equidistantly sleeved on the outer circumferential wall of the plug connector butt connection seat, and a plurality of sealing grooves adapted for the sealing rings are provided in the connection seat.
