Technical Field

[0001] The utility model belongs to the technical field of photovoltaic connectors. Specifically, it particularly relates to a photovoltaic connector. Background Technique

[0002] Photovoltaic connectors are key components used for interconnecting various components such as photovoltaic modules, busbars, controllers, and inverters in a solar photovoltaic power generation system; they play an important role in the design and installation of solar systems, providing reliable electrical connections and safety performance.

[0003] In the prior art, after retrieval, Chinese Patent No. CN202410160175.2 discloses a photovoltaic connector, which includes a first sleeve, a second sleeve, a first plug, a second plug, a first filling sleeve, a second filling sleeve, a first elastic member, and a second elastic member. Both the first sleeve and the second sleeve are provided with a head end and a tail end. The first filling sleeve is located between the first plug and the tail end of the first sleeve, the first elastic member is arranged between the tail end of the first sleeve and the first filling sleeve, the second filling sleeve is located between the second plug and the tail end of the second sleeve, and the second elastic member is arranged between the tail end of the second sleeve and the second filling sleeve.

[0004] For the fixation of existing terminals, usually a steel ring is first pressed in and fixed to the connector body, and then the cable terminal is inserted and buckled on the steel ring for fixation. In this way, the terminal assembly is prone to skew, with poor concentricity, and the mold cost is also high. For the fixation structure of the connector body with an integrated terminal, the hanging platforms of the connector body are all formed by forced ejection of the mold, making the structure prone to deformation, resulting in problems such as loose terminal fixation and unstable terminal anti - detachment force.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0006] Regarding the problems in the related art, the utility model proposes a photovoltaic connector to overcome the above - mentioned technical problems existing in the prior related art.

[0007] To solve the above - mentioned technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model provides a photovoltaic connector, which includes a connector positive - electrode main body. One end of the connector positive - electrode main body is inserted with a connector negative - electrode main body. A first sealing ring is arranged on the inner wall of the connector positive - electrode main body. A first gasket is sleeved on the outer surface of the connector positive - electrode main body. A first nut is thread - connected to the outer surface of the connector positive - electrode main body. A first cable sealing ring is arranged inside the connector positive - electrode main body. A first cable is sleeved inside the first cable sealing ring. An integrated female terminal is arranged inside the connector positive - electrode main body.

[0009] A second gasket is sleeved on the outer surface of the inner wall of the negative connector body. A second nut is threadedly connected to the outer surface of the negative connector body. A second cable seal ring is arranged inside the negative connector body. A second cable is sleeved inside the second cable seal ring. An integrated male terminal is arranged inside the negative connector body. Stainless steel claws are arranged on the outer surfaces of both the integrated female terminal and the integrated male terminal.

[0010] Furthermore, hanging platforms are fixedly connected inside both the integrated female terminal and the integrated male terminal. The integrated male terminal includes a male terminal body, and a stainless steel ring is arranged at one end of the male terminal body.

[0011] Furthermore, the integrated female terminal includes a female terminal body, and a second stainless steel ring is arranged at one end of the female terminal body.

[0012] Furthermore, external threads are arranged on the outer surfaces of both the positive connector body and the negative connector body, and the external threads respectively fit with the inner walls of the first nut and the second nut.

[0013] Furthermore, external claws are symmetrically arranged on the outer surface of the positive connector body, and an inner card slot is formed in the inner wall of the negative connector body.

[0014] Furthermore, the stainless steel ring and the male terminal body are press-connected into a whole through a stamping die, and the stainless steel claws are evenly distributed on the circumference of the stainless steel ring.

[0015] The utility model has the following beneficial effects:

[0016] 1. In view of the problems of easy skew, poor concentricity and high die cost in the assembly of existing photovoltaic connector terminals, the utility model adopts integrated terminals, including an integrated male terminal and an integrated female terminal. Stainless steel claws are arranged in the middle sections of the outer surfaces of the integrated male terminal and the integrated female terminal. After the terminals are fixed in the connector body, the terminals are fixed to the hanging platforms of the connector body through the stainless steel claws. The uniform distribution of the stainless steel claws of the terminals effectively strengthens the stability of each component, and at the same time strengthens the supporting force of the overall device, solves the problems of easy skew and poor concentricity of the terminals, and can reduce the number of dies, effectively reducing the die cost.

[0017] 2. By adopting an integrated terminal, the integrated female terminal body and the second stainless steel ring are riveted together by a mold to form a whole, which can effectively increase the stability after the terminal is fixed. Aiming at the problem that the hanging platform of the existing integrated terminal connector body is prone to deformation, resulting in loose terminal fixation and unstable terminal anti-disconnection force, the front and rear mold cores of the hanging platforms of the connector positive electrode body and the connector negative electrode body both adopt an inserting and abutting structure, which can avoid the deformation of the hanging platform structure and increase the contact area with the stainless steel claws on the integrated male terminal and the integrated female terminal, solving the problems of loose terminal fixation and unstable anti-disconnection force. Moreover, the terminal fixation structure in the connector positive electrode body and the connector negative electrode body is formed by the inserting and abutting of the mold cores, without the need for the traditional strong ejection method of the mold, making it impossible for the fixed hanging platform to deform. After the integrated terminal is fixed, the stainless steel claws can be effectively fixed on the hanging platform, and the main rod of the terminal is fixed through the body guide, eliminating the problems of terminal skew, poor concentricity, loose terminal, and poor anti-disconnection force.
