Description

Technical Field

[0001] This utility model relates to a retractable photovoltaic connector structure and belongs to the field of connector technology. Background Technology

[0002] In addition to photovoltaic (PV) cell modules, photovoltaic (PV) power generation also requires PV connectors on these modules to transmit power. Currently, PV connectors are mainly cable connectors, installed on the positive and negative leads of the PV cell modules. Patent number CN202023031336.4 provides a PV connector including a male connector and a female connector assembled and fixed together, a first nut fitted onto the tail end of the male connector, and a second nut fitted onto the tail end of the female connector. Both the first and second nuts have shock-absorbing components on their inner sides. These shock-absorbing components are elastic structures, used to seal the connection between the male connector and the first nut, as well as the female connector and the second nut. Compared to existing technologies, this PV connector not only has high structural strength, meeting the requirements of drop ball tests, but also exhibits superior sealing performance.

[0003] The disadvantage of the connector disclosed above is that after assembly, the male and female connectors lack a locking and limiting structure. The male and female connectors rely solely on their own connection and contact effect to achieve the limiting effect, which is prone to loosening. To address this, we designed a retractable photovoltaic connector structure. Utility Model Content

[0004] The purpose of this invention is to provide a retractable photovoltaic connector structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable photovoltaic connector structure, including a male connection post and a female connection post. A male terminal block is installed at one end of the male connection post, and a terminal socket is provided at the center of the male terminal block. A female terminal block is provided at one end of the female connection post, and a terminal strip is provided at the center of the female terminal block. The terminal strip is connected to the terminal socket so that the female connection post is connected to the male connection post. A positioning component is provided on the outer wall surface of the male connection post.

[0006] The positioning assembly includes a hollow protective column sleeve, a positioning pressure rod one, and a positioning pressure rod two. The hollow protective column sleeve can slide along the male connector end column. The positioning pressure rod one and the positioning pressure rod two are located at the top of the hollow protective column sleeve. The top of the female connector end column has a positioning hole one connected to the positioning pressure rod one, and the top of the male connector end column has a positioning hole two connected to the positioning pressure rod two.

[0007] In the above-mentioned retractable photovoltaic connector structure, a connecting groove is provided on one side of the hollow protective post sleeve, and a connecting plug is provided on one side of the female connecting post. The connecting plug connects with the connecting groove so that the female connecting post is retracted into the side of the male connecting post.

[0008] In the above-mentioned retractable photovoltaic connector structure, both ends of the hollow protective column sleeve are provided with fluororubber sealing rings, and both fluororubber sealing rings are sealed to the outer wall surface of the male connector end column.

[0009] In the above-mentioned retractable photovoltaic connector structure, a waterproof protective film sleeve is provided in the hollow part of the hollow protective column sleeve, and a silicone protective sleeve is provided on the inner side of the waterproof protective film sleeve.

[0010] In the above-mentioned retractable photovoltaic connector structure, both the positioning rod one and the positioning rod two can move vertically along the hollow protective sleeve, but the positioning rod one and the positioning rod two do not detach from the hollow protective sleeve.

[0011] In the above-mentioned storage-type photovoltaic connector structure, positioning hole one and positioning hole two are threaded fixing hole structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model relates to a retractable photovoltaic connector structure, which includes a positioning component on the outer wall of the male connector post. The positioning component comprises a hollow protective sleeve, a positioning rod one, and a positioning rod two. The hollow protective sleeve can slide along the male connector post. The top of the female connector post has a positioning hole one that connects to the positioning rod one, and the top of the male connector post has a positioning hole two that connects to the positioning rod two. After the female connector post is connected to the male connector post, the positioning rod one and the positioning rod two position and lock the female connector post and the male connector post, preventing the conductive terminals from being pulled loose by the cable and ensuring good contact. At the same time, a silicone protective sleeve and a waterproof protective film are set inside the hollow protective sleeve, which have a good waterproof protection effect and reduce water seepage in the gap between the female connector post and the male connector post.
