Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, and in particular relates to a sealing structure of a photovoltaic connector. Background Art

[0002] Photovoltaic connectors are special electrical connectors specifically used in solar photovoltaic systems. Photovoltaic connectors are mainly used to connect solar panels to cables, inverters or other components for electrical connection. Due to the special environment and requirements of solar panels, photovoltaic connectors usually have characteristics such as waterproof, dustproof, high temperature resistance and UV resistance to ensure the safe and reliable operation of the system.

[0003] Traditional photovoltaic connectors are mainly divided into male and female connectors, which represent the positive and negative terminals of photovoltaic modules respectively. One or more O-rings are usually used between the male and female connectors for waterproof sealing. When the product vibrates during use, the waterproof function will fail.

[0004] To this end, a sealing structure of a photovoltaic connector is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a sealing structure of a photovoltaic connector.

[0006] To achieve the above object, the utility model provides a sealing structure of a photovoltaic connector, comprising:

[0007] Male connector, including shell and plug;

[0008] A female connector, wherein an end of the female connector close to the male connector is provided with a socket corresponding to the plug;

[0009] The sealing member comprises a sealing sleeve, and a plurality of sealing rings protrude from the outside of the sealing sleeve at intervals; the sealing sleeve is sleeved on one end of the plug close to the shell, and the outer side of the sealing ring abuts against the inner wall of the jack.

[0010] Preferably, a clamping hole is formed at one end of the jack close to the male head corresponding to the sealing sleeve, an end of the sealing sleeve away from the male head abuts against an inner end wall of the clamping hole, and an outer wall of the sealing ring abuts against an inner wall of the clamping hole.

[0011] Preferably, a retaining ring is fixedly connected to one end of the plug close to the housing, and the end of the sealing sleeve abuts against the retaining ring.

[0012] Compared with the prior art, the utility model has the following advantages and technical effects:

[0013] The seal is used to seal the connection gap between the male and female heads at the connection between the male and female heads. The seal connects multiple sealing rings through a sealing sleeve to form a whole. The contact area between the sealing sleeve and the plug is large and not easy to move, which provides good support and position restriction for the sealing ring. The sealing ring will not be shifted due to vibration and thus cause waterproof failure. Multiple sealing rings form layers of seals to ensure a good sealing effect.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1 to 6As shown, this embodiment provides a sealing structure of a photovoltaic connector, including:

[0025] The male connector 1 includes a housing 11 and a plug 12;

[0026] The female connector 2 has a socket 21 at one end of the female connector 2 close to the male connector 1 and corresponding to the plug 12;

[0027] The sealing member 3 comprises a sealing sleeve 31 , and a plurality of sealing rings 32 protrude from the outside of the sealing sleeve 31 at intervals; the sealing sleeve 31 is sleeved on one end of the plug 12 close to the housing 11 , and the outer side of the sealing ring 32 abuts against the inner wall of the insertion hole 21 .

[0028] The seal 3 seals the connection gap between the male head 1 and the female head 2 at the connection between the male head 1 and the female head 2. The seal 3 connects the multiple sealing rings 32 through the sealing sleeve 31 to form a whole. The contact area between the sealing sleeve 31 and the plug 12 is large and not easy to move. It plays a good supporting and position limiting role for the sealing ring 32. The sealing ring 32 will not be offset due to vibration and cause waterproof failure. The multiple sealing rings 32 form layers of seals to ensure a good sealing effect.

[0029] A further optimized solution is that a snap-in hole 211 is opened at one end of the jack 21 close to the male connector 1 corresponding to the sealing sleeve 31, the end of the sealing sleeve 31 away from the male connector 1 abuts against the inner end wall of the snap-in hole 211, and the outer wall of the sealing ring 32 abuts against the inner wall of the snap-in hole 211.

[0030] The clamping hole 211 and the insertion hole 21 form a step, which limits the sealing sleeve 31 from deviating into the insertion hole 21, further strengthens the position limitation of the sealing member 3, and ensures the sealing effect.

[0031] According to a further optimized solution, a retaining ring 13 is fixedly connected to one end of the plug 12 close to the housing 11 , and an end of the sealing sleeve 31 abuts against the retaining ring 13 .

[0032] The retaining ring 13 limits the sealing sleeve 31 from deviating outward from the insertion hole 21 , and together with the clamping hole 211 , limits the position of the sealing member 3 from both ends to ensure the sealing effect.

[0033] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0034] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
