Abstract

The invention discloses a cover opening tool for a terminal box, comprising a handle and an L-shaped cover opener. The L-shaped cover opener comprises a connecting end, a vertical bar and an inserting bar, wherein the vertical bar is vertically connected with the inserting bar as a whole, and the joint is arc-shaped. The thickness of the inserting bar head is smaller than the gap formed after fastening a box cover and a box body, and an upper end of the connecting end is fixedly connected with the handle. During maintenance, the inserting bar of the L-shaped cover opener is inserted into the gap formed after fastening the box cover and the box body, and then the handle is pulled up gently, so as to separate the fastening parts of the box cover and the box body. Meanwhile, the other hand holds the box cover and pulls upward forcefully, so that the box cover of the terminal box can be opened without hard artificial breaking, or replacing the terminal box. During maintenance, the box cover can be easily and conveniently opened without damaging the terminal box and maintenance labor intensity is reduced. By using the cover opening tool for terminal box, the box cover can be removed easily without changing the engaging manner of the box body and the box cover, or damaging the terminal box.

Description

The terminal box instrument of uncapping

Technical field:

The present invention relates to the production of solar module, the terminal box that the relates in particular to solar module instrument of uncapping.

Background technology:

The output voltage of monomer solar cell, electric current and power are all very little, and in general, output voltage has only about 0.5V, and power output has only 1～4W, can not satisfy the requirement as application of power.For improving power output, need a plurality of cells are rationally coupled together, and be packaged into assembly.In the more powerful occasion of needs, then need a plurality of assemblies are connected to become square formation, so that the bigger electric current of numerical value, voltage output to be provided to load.

Solar battery component junction box is extremely important in the composition of solar components, and main effect is that the electric power that solar cell produces is connected with outside line, and the protection internal wiring is avoided the destruction of extraneous factor.The base plate of terminal box sticks together closely by the backboard of silica gel and assembly, and the internal wiring in the terminal box is drawn outside the terminal box by lead-out wire, by lead-out wire internal wiring and External cable is linked together, and makes assembly and External cable conducting.Diode is installed in the terminal box, guarantees that assembly can also operate as normal when being in the light.

Existing terminal box is for the ease of installing, all adopt box body to add the mode of lid, earlier box body is bonded on the backboard of assembly closely during production, electric current lead-out wire in the assembly is connected in the box body, cover lid then, terminal box adopts lid to cover the mode of box body, adopt the combination of pawl between the lid inboard and the box body outside, lid only needs when mounted gently down by getting final product, and lid is fastened on the box body firmly, can avoids connector cover in the carrying of assembly or use, to come off.But the terminal box of this kind structure, lid is in case just be difficult to pull down with the box body fastening, so just bring certain difficulty to maintenance, because the distance of lid lower surface and box body bottom is less, can't all be manually to break off with the fingers and thumb firmly lid is separated from box body now with " word rises " tamper tool, but whole terminal box is scrapped, to new terminal box be installed on the assembly backboard again, not only cause resource and waste of time, and strengthened hand labor intensity.In order to allow lid break away from box body easily and do not destroy terminal box, the applicant has invented a kind of instrument of uncapping of terminal box, use this terminal box instrument of uncapping, can under the mode that does not change the engagement of terminal box box body and lid, like a cork lid be pulled down, simultaneously terminal box is destroyed.

Summary of the invention:

For the lid that overcomes present terminal box separates ruined shortcoming with box body because of difficulty, the invention provides a kind of terminal box instrument of uncapping, adopt this terminal box instrument of uncapping, can be easily the lid of terminal box be taken off from box body, simultaneously do not destroy terminal box, terminal box is reusable.

The technical solution adopted in the present invention is:

The described terminal box instrument of uncapping, it is characterized in that: it comprises handle and L shaped device for releasing closures, L shaped device for releasing closures is made up of link, vertical bar and insertion rod, vertically bar is vertical with insertion rod links into an integrated entity, the junction is circular arc, gap after the head thickness of insertion rod fastens less than lid and box body, fixedly connected with handle in the upper end of link.

Further, described handle is by the connecting thread hole and hold handle and form, and the epimere of the link on the L shaped device for releasing closures is a thread segment, fixedlys connected by screw thread between L shaped device for releasing closures and the handle.

Further, described handle by connect taper hole and and hold handle and form, the longitudinal cross-section of the link of L shaped device for releasing closures is shaped as and is connected the corresponding cone of taper hole, link is sleeved in the connection taper hole.

Further, the cross sectional shape of the head of described insertion rod is a right-angled trapezium, the gap after last bottom width fastens less than lid and box body, and following bottom width is the thickness of vertical bar.

Adopt the terminal box of this solar module instrument of uncapping, in the insertion rod insertion lid and the gap behind the box body fastening with L shaped device for releasing closures when maintenance, upwards pull handle then gently, lid promptly separates with the fastening part of box body, the another hand catches lid firmly upwards to carry again, so just the lid of terminal box can be opened, need not manually to break off with the fingers and thumb firmly, more do not need the rewiring box, when maintenance, it is light not only to open the lid, can not damage terminal box again, reduce maintenance labour intensity, this terminal box instrument of uncapping has been arranged, can under the mode that does not change the engagement of terminal box box body and lid, like a cork lid be pulled down, terminal box is damaged.
