Description
Technical field
The present invention relates to photovoltaic accessory technical field, especially relate to a kind of locking photovoltaic connector.
Background technology
Existing photovoltaic connector is in test certification and onsite application process, and nut easily gets loose from male plug or female plug or comes off, and then causes the danger such as the corrosion of inner five metals conducting position and electric leakage.Meanwhile, increase pulling force by gluing between nut and housing in the market, glue can slowly with connector material generation chemical reaction, reduction nut mechanical strength, this adds increased the risk of the permanent reliability of product.
Summary of the invention
The object of the invention is to propose a kind of locking photovoltaic connector, not only quick for installation, and the reliability after connecting can be ensured.
Locking photovoltaic connector of the present invention comprises plug and nut, one end of described plug is provided with external screw thread, described nut is provided with the internal thread coordinated with described external screw thread, key is that the lateral surface of described plug is provided with outstanding plug locking teeth, and the medial surface of described nut is provided with the nut locking teeth of convex; Described plug locking teeth and nut locking teeth are equipped with guiding surface and non-return face, the non-return face of described plug locking teeth and the guiding surface of nut locking teeth all screw direction toward nut, and the guiding surface of described plug locking teeth and the non-return face of nut locking teeth all screw direction back on nut; Described plug locking teeth and/or nut locking teeth are made up of the material of elastically deformable.
Plug and nut, by threaded engagement, are fixedly connected with nut to make plug.Screw in the process of nut at plug, after nut locking teeth contacts with plug locking teeth, under the guide effect of the guiding surface of nut locking teeth, plug locking teeth, certain deformation can be there is in nut locking teeth and/or nut locking teeth, such nut locking teeth can cross plug locking teeth, nut is rotated further, until cap rotation puts in place, plug and nut fastening.And in use, if nut rotates backward, because the non-return face of nut locking teeth contacts with the non-return face of plug locking teeth, prevent nut locking teeth to cross plug locking teeth, also just prevent nut to continue to rotate backward, thus achieve locking functions.
Further, described nut locking teeth is positioned at the front end of nut; Described plug locking teeth is positioned at the male ends of plug, and only have nut like this close to when screwing, nut locking teeth just can contact with plug locking teeth, so just the installation of more convenient nut.
Further, the end of described plug locking teeth and/or nut locking teeth is circular arc or is provided with chamfering, to reduce wearing and tearing when plug locking teeth contacts with nut locking teeth, and reduce in nut screwing operations, the resistance be subject to when nut locking teeth crosses plug locking teeth.
Further, described nut locking teeth has multiple, and is uniformly distributed in the medial surface of nut, locking to ensure that nut can realize non-return in multiple angle.
Further, the non-return face of described plug locking teeth is perpendicular to the tangential direction of plug periphery, the non-return face of described nut locking teeth is perpendicular to nut medial surface tangential direction, the resistance being parallel to nut medial surface tangential direction is only had between after the non-return face of such plug locking teeth contacts with the non-return face of nut locking teeth, this resistance can not cause nut locking teeth and/or nut locking teeth generation deformation, thus improves non-return effect.
Locking photovoltaic connector of the present invention is similar to the anti-loose structure of click fit form by arranging, under the prerequisite not affecting property easy for installation, avoid the generation of situation and the consequent security incident got loose between plug and nut, reach best technique effect by most economical means, there is very high commercial value.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the locking photovoltaic connector of the present embodiment comprises plug 1 and nut 2, one end of described plug 1 is provided with external screw thread 11, described nut 2 is provided with the internal thread 21 coordinated with described external screw thread 11, key is that the lateral surface of external screw thread 11 end of described plug 1 is provided with outstanding plug locking teeth 12, and the medial surface of described nut 2 front end is provided with the nut locking teeth 22 of convex; Described plug locking teeth 12 and nut locking teeth 22 are equipped with guiding surface and non-return face, the non-return face 122 of described plug locking teeth 12 and the guiding surface 221 of nut locking teeth 22 all screw direction toward nut 2, and the guiding surface 121 of described plug locking teeth 12 and the non-return face 222 of nut locking teeth 22 all screw direction back on nut 2; Described plug locking teeth 12 and/or nut locking teeth 22 are made up of the material (as plastics) of elastically deformable.
The end of plug locking teeth 12 and nut locking teeth 22 is circular arc or is provided with chamfering, to reduce wearing and tearing when plug locking teeth 12 contacts with nut locking teeth 22, and reduce in nut 2 screwing operations, the resistance be subject to when nut locking teeth 22 crosses plug locking teeth 12.
Nut locking teeth 22 has multiple, and is uniformly distributed in the medial surface of nut 2, locking to ensure that nut 2 can realize non-return in multiple angle.
The non-return face 122 of plug locking teeth 12 is perpendicular to the tangential direction of plug 1 periphery, the non-return face 222 of described nut locking teeth 22 is perpendicular to nut 2 medial surface tangential direction, the resistance being parallel to nut 2 medial surface tangential direction is only had between after the non-return face 122 of such plug locking teeth 12 contacts with the non-return face 222 of nut locking teeth 22, this resistance can not cause nut locking teeth 22 and/or nut locking teeth 22 that deformation occurs, thus improves non-return effect.
The principle of above-mentioned locking photovoltaic connector is as follows:
Plug 1 and nut 2, by threaded engagement, are fixedly connected with nut 2 to make plug 1.When nut 2 is close to when screwing, nut locking teeth 22 can contact with plug locking teeth 12, under the guide effect of the guiding surface 221,121 of nut locking teeth 22, plug locking teeth 12, certain deformation can be there is in nut locking teeth 22 and/or nut locking teeth 22, such nut locking teeth 22 can cross plug locking teeth 12, nut 2 is rotated further, until nut 2 is rotated in place, plug 1 is fastening with nut 2.And in use, if nut 2 rotates backward, because the non-return face 222 of nut locking teeth 22 contacts with the non-return face 122 of plug locking teeth 12, nut locking teeth 22 is prevented to cross plug locking teeth 12, also just prevent nut 2 to continue to rotate backward, thus achieve locking functions.
In the present embodiment, plug 1 is male plug, and certainly, above-mentioned plug 1 also can be female plug, and the setting of its anti-loose structure and principle are all identical, repeat no more herein.
