Description
Technical field
The utility model relates to a kind of photovoltaic connector, the connection for component in photovoltaic system.
Background technology
Solar energy is developed rapidly, photovoltaic system is also applied as clean energy resource in the today for increasingly advocating environmental protection
It is more and more extensive.In photovoltaic system, the connection between component is realized by photovoltaic connector, but in the peace of component
During dress, connector and cable will often bear larger pulling force, easily disconnect, come off.Main flow connector in industry at present
Being fallen using installation retaining ring to prevent anti-avulsion, retaining ring is then reinforced by ultrasonic welding, once ultrasound failure, then can cause
Retaining ring is failed, and causes connection to disconnect, and risk is brought to component, and retaining ring is needed to produce, installed and ultrasound welds, and process is numerous
It is more, consume material and artificial, cost height.
The content of the invention
The utility model is above-mentioned in order to overcome the shortcomings of, there is provided a kind of photovoltaic connector, including plastic casing and metal
Inner core, the inside of plastic casing is cylindrical cavity A and cylindrical cavity B, and cavity A diameter is more than cavity B diameter, cavity
A is provided with the back-off of several radially even distributions with cavity B intersections, and the inwall angle of back-off and cavity B is 5-30 degree, falls
Button inner side forms truncated cone-shaped, and the back-off and plastic casing are structure as a whole；
The metal inside includes binding post, back-up ring, transition round platform, the connecting pole from left to right set gradually, transition circle
Be brought into close contact on the inside of platform and back-off, back-up ring diameter is more than transition round platform bottom surface diameter, connection outer surface of column be evenly distributed with and
The hangnail that back-off is engaged, the binding post, back-up ring, transition round platform, connecting pole, hangnail are structure as a whole.
Preferably, the quantity of the back-off is 6.
Preferably, the width of the hangnail is equal to the gap width between adjacent back-off, and the width of back-off is at least hangnail
3 times of width.
The beneficial effects of the utility model are：Photovoltaic connector provided by the utility model need not install retaining ring,
Also the material requested loss of production retaining ring is just eliminated, the labour cost of production, installation and ultrasonic welding is eliminated, reduces into
This；From structure, first, the connecting pole of metal inside passes through back-off, and then, the hangnail on connecting pole is between adjacent back-off
Gap pass through, afterwards, closely coupled on the inside of transition round platform and back-off, back-up ring prevents metal inside from continuing forward, now slightly to turn
Dynamic metal inside, back-off block hangnail, and metal inside, which has been effectively ensured, to be retreated, and having reached prevents connector from disconnecting, coming off
Purpose, avoid retaining ring and fail the risk brought to component.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is the schematic diagram of the utility model cutting plane；
Fig. 2 is top view of the present utility model；
Fig. 3 is C partial enlarged drawing.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
Such as Fig. 1, shown in Fig. 2, photovoltaic connector provided by the utility model includes plastic casing 1 and metal inside 2, modeling
The inside of material shell 1 is cylindrical cavity A3 and cylindrical cavity B4, and cavity A3 diameter is more than cavity B 4 diameter, cavity A
3 are provided with the back-off 5 of 6 radially even distributions, 15 degree of back-off 5 and cavity B4 inwall angle, back-off 5 with cavity B4 intersections
Inner side forms truncated cone-shaped, and the back-off 5 and plastic casing 1 are structure as a whole；
The metal inside 2 includes binding post 6, back-up ring 7, transition round platform 8, the connecting pole 9 from left to right set gradually, mistake
Cross round platform 8 to be brought into close contact with the inner side of back-off 5, the diameter of back-up ring 7 is more than the bottom surface diameter of transition round platform 8, and the outer surface of connecting pole 9 is uniform
The hangnail 10 being engaged with back-off 5 is distributed with, the gap width between the width of hangnail 10 and adjacent back-off 5 is equal, such as Fig. 3 institutes
Show, K1=K2, the width of back-off 5 is 3 times of the width of hangnail 10, as shown in figure 3, K3=3*K1, the binding post 6, back-up ring 7, mistake
Round platform 8, connecting pole 9, hangnail 10 is crossed to be structure as a whole.
Photovoltaic connector provided by the utility model need not install retaining ring, also just eliminate needed for production retaining ring
Spillage of material, the labour cost of production, installation and ultrasonic welding is eliminated, reduces cost；From structure, first, metal
The connecting pole of inner core passes through back-off, and then, the hangnail on connecting pole passes through from the gap between adjacent back-off, afterwards, transition circle
For platform with closely coupled on the inside of back-off, back-up ring prevents metal inside from continuing forward, now slightly to rotate metal inside, back-off blocks down
Thorn, metal inside, which has been effectively ensured, to be retreated, and reached the purpose for preventing that connector from disconnecting, coming off, and avoid retaining ring mistake
Imitate the risk brought to component.
Above-mentioned foundation the utility model is enlightenment, and by above-mentioned description, relevant staff completely can be not
In the range of deviateing this item utility model technological thought, various changes and amendments are carried out.This item utility model it is technical
Scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
