Abstract

The purpose of this utility model proposes a kind of waterproof photovoltaic connector, effectively to ensure the water resistance after photovoltaic connector connection and reliability.Waterproof photovoltaic connector of the present utility model comprises in connector body, nut and the waterproof be made up of elastomeric material to be filled in, one end of described connector body is provided with the external screw thread coordinated with described nut, the end of thread of described connector body is provided with open-ended cavity, and connector body is provided with the cable passage communicated with described cavity; In described waterproof, plug is provided with through hole and several claws around described through hole end, and one end of described claw is connected with interior plug of waterproof, and in waterproof, the length of plug is longer than the length of described cavity.Waterproof photovoltaic connector of the present utility model utilizes plug in waterproof to instead of the claw of conventional photovoltaic connector plug, thus causes connector jaw structure to occur crookedly even rupturing under avoiding long-time effect of stress, and the generation of consequent security incident.

Description

A kind of waterproof photovoltaic connector
Technical field
The present invention relates to photovoltaic accessory technical field, especially relate to a kind of waterproof photovoltaic connector.
Background technology
Photovoltaic connector is the important devices of solar photovoltaic industry, and its connection reliability is important performance parameter.Consider that photovoltaic plant to be intake the short circuit caused and the safety problem occurred because of connector, photovoltaic connector must waterproof and sturdy and durable, to bear Exposure to Sunlight and to drench with rain.
The connector that usual classification of waterproof is higher, connector plug screw-top design is outside open claws minor structure, with there is the assembling of larger flexible sealing shroud, then nut pretension is used, cable is inserted into after connector inside puts in place, lock nut, and the inner jaw structure of connector tightly wraps sealing shroud, the gap of cable and nut junction covers by sealing shroud completely, thus reaches waterproof effect.But for a long time effect of stress easily causes connector jaw structure to occur crookedly even rupturing, and is difficult to ensure to the water resistance of connector.
Summary of the invention
The object of the invention is to propose a kind of waterproof photovoltaic connector, effectively to ensure the water resistance after photovoltaic connector connection and reliability.
Waterproof photovoltaic connector of the present invention comprises in connector body, nut and the waterproof be made up of elastomeric material to be filled in, one end of described connector body is provided with the external screw thread coordinated with described nut, the end of thread of described connector body is provided with open-ended cavity, and connector body is provided with the cable passage communicated with described cavity; In described waterproof, plug is provided with through hole and several claws around described through hole end, and one end of described claw is connected with interior plug of waterproof, and in waterproof, the length of plug is longer than the length of described cavity.
In use, first plug in waterproof is put in the cavity of the connector body end of thread, then cable is passed successively the through hole filled in cable passage and waterproof, then nut is screwed on connector body.Because the length of filling in waterproof is longer than the length of described cavity, therefore be plugged with part in waterproof and be exposed to cavity outside, in the process screwed gradually at nut like this, nut can oppress plug in waterproof, thus make the claw of plug in waterproof shrink and tightly wrap cable, achieve waterproof.Because the connector body of above-mentioned waterproof photovoltaic connector does not arrange claw, the connective stability between connector body and nut and the permanent reliability used therefore can not be affected.
Further, described cavity is bell mouth shape structure, and in described waterproof, plug is taper or round table-like structure towards one end of connector body.Like this when nut is filled in connector body direction compressing waterproof, in waterproof, the claw of plug will draw in gradually under the effect of cavity inner wall, finally tightly wraps cable.In like manner, the inner side of described nut is bell mouth shape structure, and in described waterproof, plug is taper or round table-like structure towards one end of nut, also can realize waterproof like this to the cable being positioned at nut side.
Waterproof photovoltaic connector of the present invention utilizes plug in waterproof to instead of the claw of conventional photovoltaic connector plug, thus causes connector jaw structure to occur crookedly even rupturing under avoiding long-time effect of stress, and the generation of consequent security incident.
Accompanying drawing explanation
Fig. 1 is the cutaway view of photovoltaic connector of the present invention.
Fig. 2 is the structural representation of plug in waterproof of the present invention.
Accompanying drawing represents: 1, connector body; 11, cavity; 12, cable passage; 2, nut; 3, plug in waterproof; 31, through hole; 32, claw.
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 waterproof photovoltaic connector of the present embodiment comprises plug 3 in connector body 1, nut 2 and the waterproof be made up of elastomeric material, one end of described connector body 1 is provided with the external screw thread coordinated with described nut 2, the end of thread of described connector body 1 is provided with open-ended cavity 11, and connector body 1 is provided with the cable passage 12 communicated with described cavity 11; Plug 3 is provided with through hole 31 and several claws 32 around described through hole 31 two ends in described waterproof, one end of described claw 32 with fill in 3 in waterproof and is connected, the length that waterproof is interior fills in 3 is longer than the length of described cavity 11.
Described cavity 11 is bell mouth shape structure, and the inner side of described nut 2 is bell mouth shape structure, and in described waterproof, the two ends of plug 3 are round table-like structure.
In use, first putting in the cavity 11 of connector body 1 end of thread by filling in 3 in waterproof, then cable being passed successively the through hole 31 of plug 3 in cable passage 12 and waterproof, then nut 2 is screwed on connector body 1.Because the length of filling in 3 in waterproof is longer than the length of described cavity 11, therefore in waterproof, plug 3 has part to be exposed to cavity 11 outside, in the process screwed gradually at nut 2 like this, nut 2 can oppress plug 3 in waterproof, the claw 32 at plug 3 two ends will draw in gradually under the effect of cavity 11 inwall and nut 2 inwall in waterproof, finally tightly wrap cable, achieve waterproof.Because the connector body 1 of above-mentioned waterproof photovoltaic connector does not arrange claw 32, the reliability that therefore can not affect the connective stability between connector body 1 and nut 2 and use for a long time.
