Description
Technical field
The invention belongs to electric connection technology fields, more particularly to a kind of connector of photovoltaic cell.
Background technique
Connector is very important accessory in photovoltaic power generation, to realize the electrical connection between solar energy electroplax.Due to
Solar power station is long using the time, and use environment is severe, very high to the stability of connector, reliability requirement.In the prior art
The connector of mainstream be it is such (as shown in Figure 1), by taking a male connector or female as an example, current-carrying part and insulation division can be divided into
Point, current-carrying part is wrapped in insulated part；Current-carrying part is made of electric conductor 2 and the riveting of cable 1, and insulated part is then more
Complexity, including housing main body 7 and nut 3, the two is threadedly coupled, and further includes the fastener of a gaily decorated basket shape, fastener is by fastening
Set 4 and internal lining pipe 5 form, and when tightening nuts, its internal diameter reduces, and are subjected to displacement it not for banding cable；Electric conductor 2
Main body be it is cylindric, on outer peripheral surface have several locking tooths 21 to extend backward and outward, insulated part further include one annular
Non-return ring 8,8 one end of Non-return ring contact on locking tooth 21, and the other end is withstood on the fastener of gaily decorated basket shape.When each component sequence is pacified
It fills, after tightening nuts, pressure of the electric conductor by fastener circumferentially not can rotate or loosen；By the pressure of Non-return ring,
It can not axially retreat；Locking tooth expands the outer diameter of electric conductor, thus is limited by housing main body, it is axial can not before
Into.A stable connector construction is constituted as a result,.
In use it was found that the structure of such connector designs, gaily decorated basket shape fastener by cable banding after,
Nut continues to tighten, and fastener, Non-return ring, cable, electric conductor will be pushed to continue forward, until the locking tooth of electric conductor contacts
Housing main body, each component all directions are all in lockup state.In the entire service life of connector, this shape will be all kept
State, it is possible to reach 10-20.After the locking tooth of electric conductor contacts housing main body, housing main body just has a stress, it is contemplated that
Its time to meet with stresses is so long, and this part is often shell part the weakest, just has and shell cracking occurs
Risk.Especially in desert area, have such accident and occur, the risks such as leak short circuit or even electric leakage electric shock may be brought.
Summary of the invention
The object of the present invention is to provide a kind of connectors of more reliable photovoltaic cell.
For this purpose, the technical solution adopted by the present invention is that such: a kind of connector of photovoltaic cell, including current-carrying part and
Insulated part, current-carrying part are wrapped in insulated part；Current-carrying part is made of electric conductor and cable riveting, insulation division subpackage
Housing main body and nut are included, the two is threadedly coupled, the inner cavity of housing main body, and the diameter of front is less than rear portion, forms a step
Face；Insulated part further includes the fastener of a gaily decorated basket shape, and it is outer to banding cable to be socketed in cable；
It is characterized by:
Conductive phosphor bodies are cylindric, the retaining ring with a rigidity on outer peripheral surface；Insulated part further includes an anterior cannula, protheca
The head of pipe is ring-type, is covered outside electric conductor；The internal diameter of protheca tube head is greater than the outer diameter of electric conductor and is less than stopping for electric conductor
The outer diameter of ring is moved back, the outer diameter of protheca tube head is greater than the internal diameter of housing main body inner cavity front, to contradict in the step surface
On.
Further, the internal diameter of anterior cannula main body is greater than the internal diameter of protheca tube head, and two inner walls are connected by chamfered transition
It connects.
Such technical solution also can be used: there is several check teeth to extend internally, check tooth institute in anterior cannula main body
The internal diameter of the ring of composition be greater than electric conductor outer diameter and be less than retaining ring outer diameter, electric conductor pass through protheca tube head when, retaining
Ring makes check tooth, and deformation occurs, and retaining ring is touched after passing through check tooth by check tooth top.
The present invention relates to anterior cannulas, wherein anterior cannula only defines cricoid head in most basic technical solution, this
The internal-and external diameter of kind situation head portion and main body is the same, therefore actually can not clearly distinguish head and main body；
Anterior cannula role is subject to the electric conductor stress that retaining annulus comes in extrusion process forward, even if there is the risks such as cracking,
It is to occur in anterior cannula rather than occur on housing main body, in addition anterior cannula is integrally placed in housing main body, therefore exhausted to its
The requirement of the physicochemical properties such as edge is lower than housing main body, can be with so that manufacturer is possible to the material that selection has certain elasticity
Offset electric conductor bring stress.Even therefore most basic technical solution, also can solve technical problem of the invention.At this
In the case of kind, it is also necessary to the design such as application Non-return ring in the prior art, to prevent the movement of electric conductor backward.
In further technical solution, anterior cannula is provided with the different head of internal diameter and main body, and with chamfered transition
Connection；Preferably agree with the retaining ring on electric conductor, is better protected from problem of Cracking.
In another technical solution, check tooth is also had in anterior cannula, retaining ring is contacted, actually by original retaining
The effect of circle has been integrated into anterior cannula, and two kinds of functions can be realized in a component.The present invention will be in the prior art outside electric conductor
Locking tooth on circumferential surface becomes the retaining ring of a rigidity, and the locking tooth of script waits meeting during installation, and deformation occurs, toward inside contracting, installs
It pops up and again afterwards；And retaining ring is rigid, will not deformation occurs, can make check tooth when being contradicted with check tooth deformation occurs,
To pass through check tooth, stopping function can be better achieved.
