Description
Technical field
The utility model is related to a kind of photovoltaic connectors for photovoltaic art.
Background technology
Photovoltaic connector is in order to ensure that connection is reliable, when nut is locked, it will usually a gaily decorated basket be arranged in inside, when avoiding long
Between after, nut occurs loosening phenomenon.Although the gaily decorated basket can increase the connection reliability of nut, it is also needed in water proofing property
In addition seals and other component is set to realize, causes part various, installation is complicated.
Invention content
In order to overcome above-mentioned deficiency in the prior art, it is to ensure that coupling mechanism force increases water proofing property again that the utility model, which provides a kind of,
The photovoltaic connector of energy.
The technical solution that the utility model solves the above problems is as follows：
A kind of photovoltaic connector, including positive connector and cathode connector, positive connector and cathode connector difference
Including connector body, the connector connecting pin for connecting another polarity connector is arranged in one end of connector body, another
The cable connection end for connecting cable is arranged in end, and threaded portion is provided on the cable connection end, and screw thread revolves on threaded portion
Tightly there is nut, it is characterised in that：Pad is equipped with padded sleeve between the threaded portion and nut.
Preferably, the both ends of padded sleeve are respectively first end and second end, padded sleeve is set as from middle part respectively to
The pipe sleeve shape that one end, second end gradually reduce.
Preferably, the gradient that middle part is gradually contracted to first end is less than the inclination that middle part is gradually contracted to second end
Degree.
Preferably, first end is pressed in the port of threaded portion, second end is pressed on the inside of nut.
Preferably, the end of nut is equipped with a circle locking teeth.
Preferably, locking teeth includes the first tooth in, the second tooth and between when being connected to the first tooth in the second tooth
Increment, first tooth while gradient be less than the second tooth while gradient, the locking teeth equidistantly distributed.
Preferably, offering multiple grooves on connector body, the groove is symmetrically distributed in connector body
Both sides.
Padded sleeve is set between nut and the threaded portion of connector body, and padded sleeve is pipe sleeve shape, and small in ends, intermediate
Greatly, the relatively small one end of padded sleeve is arranged in threaded portion, and the other end is set by nut pressure, and the end set of nut has locking teeth,
After screwing, is pressed by padded sleeve in the middle part of setting while expansion is stretched between nut and threaded portion and reaches the two between each other into one
Step locking, avoids nut from popping out.Locking teeth has also further locked nut and threaded portion.In addition, the setting of padded sleeve,
Also increase the water resistance of the cable connection end of connector body.
Groove on connector body can increase the creepage distance of connector, improve safety.
The beneficial effects of the utility model are：The utility model is improved by the structure to connector, is increased
Water resistance, and can guarantee the coupling mechanism force of nut simultaneously.
Description of the drawings
Fig. 1 is the structural schematic diagram of utility model.
Specific implementation mode
Utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of photovoltaic connector, including positive connector and cathode connector, positive connector and cathode
Connector respectively includes connector body 8, and the connector for connecting another polarity connector is arranged in one end of connector body
Connecting pin 9, the other end are arranged the cable connection end 7 for connecting cable, threaded portion, spiral shell are provided on the cable connection end
Screw thread has screwed nut 1 in line portion, and pad is equipped with padded sleeve 6 between threaded portion and nut.The both ends of padded sleeve are respectively first end 5
With second end 3, padded sleeve is set as the pipe sleeve shape gradually reduced to first end, second end respectively from middle part.Middle part gradually reduces
Gradient to first end is less than middle part and is gradually contracted to the gradient of second end.First end 5 is pressed in the port of threaded portion,
Second end 3 is pressed on the inside of nut.
The end of nut is equipped with a circle locking teeth 2.Locking teeth 2 includes the first tooth in, the second tooth and is connected to first
Tooth in the second tooth between increment, first tooth while gradient be less than the second tooth while gradient, the lock
Tight tooth equidistantly distributed.
Multiple grooves 10 are offered on connector body, groove is symmetrically distributed in the both sides of connector body.
Elastic buckle 13 is set on the connector connecting pin of positive connector, is set on the connector connecting pin of cathode connector
Button hole 11 is set, Elastic buckle accommodating hole 12 is arranged in button hole rear, and length and the Elastic buckle of Elastic buckle accommodating hole are caught in length
It is identical.
Padded sleeve 6 is set between nut and the threaded portion of connector body, padded sleeve is pipe sleeve shape, and small in ends, in
Between it is big, the relatively small one end of padded sleeve is arranged in threaded portion, and the other end is set by the pressure of nut 1, and the end set of nut has locking
Tooth 2 after screwing, is pressed in the middle part of setting by padded sleeve while expansion is stretched between nut and threaded portion and reaches the two between each other
Further locking, avoids nut from popping out.Locking teeth 2 has also further locked nut and threaded portion.In addition, padded sleeve
Setting, also increases the water resistance of the cable connection end of connector body.
Groove 10 on connector body can increase the creepage distance of connector, improve safety.
The utility model is improved by the structure to connector, increases water resistance, and can guarantee spiral shell simultaneously
The coupling mechanism force of cap.
