Abstract
The invention discloses a junction box for a solar cell. The junction box comprises a box body and a busbar connection device. The busbar connection device consists of a connecting sheet and an elastic piece, wherein the longitudinal section of the connecting sheet is spoon-shaped, and the head part of the connecting sheet is positioned in an accommodation cavity at the bottom of the box body and provided with a first through hole; the elastic piece is 'Omega'-shaped, and one end of the elastic piece is provided with a second through hole; the end, with the second through hole, of the elastic piece is extended into the head part of the connecting sheet by the first through hole, and is positioned in the accommodation cavity at the bottom of the box body together with the head part of the connecting piece; and the edge of the first through hole of the connecting sheet also has an upturned supporting end. The junction box for the solar cell only has two parts, and the two parts are in splicing fit with each other, highly interchangeable and simple and convenient to maintain.
Description
Technical field
The present invention relates to a kind of solar battery connecting box, comprise box body and busbar jockey.
Background technology
Solar cell obtains application more and more widely because of environmental protection.Usually the electric current that produces of solar cell is by busbar, and the terminal box by being connected with busbar again is transferred to follow-up usefulness electric line, and the fixedly connected mode of busbar and the common employing of terminal box at present is connected.Adopt fixedly connected mode a tie point can occur, the generated output of the contact resistance meeting consuming cells that tie point exists, and also because solar power generation has low voltage and high current, the tie point place is overheated easily, can threaten line security.In addition, terminal box is fixedlyed connected with busbar, when any one goes wrong when busbar or terminal box, just both all must be changed.Therefore, how the contact resistance with busbar and terminal box junction reduces, and safeguards simple and conveniently simultaneously, becomes a technical problem that is faced at present.
Summary of the invention
The object of the present invention is to provide a kind of solar battery connecting box, busbar and terminal box are easy to connect in this terminal box, and operating efficiency improves.
Technical scheme of the present invention for this reason is such: solar battery connecting box, comprise box body and busbar jockey, the busbar jockey is made up of an a connecting piece and a flexure strip, the longitudinal section of described brace is a scoop, its head is inserted in the accommodation aperture of box body bottom, and has one first through hole; Described flexure strip is " Ω " shape, and the one end has one second through hole; The end that flexure strip has second through hole stretches into the head of brace by first through hole, places the accommodation aperture of box body bottom jointly; The edge of brace first through hole also has a support end that is upturned.
Further improve as the present invention, the end away from second through hole of described flexure strip is connected with box body.
Further improve as the present invention, the end away from second through hole of described flexure strip has an outside crotch, hooks the antetheca of accommodation aperture.In addition, also can make an end band one screens hole away from second through hole of described flexure strip, the part of accommodation aperture antetheca is passed this screens hole, thereby both are connected.
After the present invention installed, the end that flexure strip has second through hole stretched into the scoop head of brace by first through hole, and under its elastic reaction, a limit of its " Ω " shape will be pressed on the antetheca of brace head; Can with screwdriver or similarly second through hole of instrument by flexure strip stretch in the brace head, again because there is a support end that is upturned at the edge of brace first through hole, so can slightly prize flexure strip with it as fulcrum.Thus, the space will occur between the head antetheca of the limit of aforesaid flexure strip and brace, busbar can stretch in this space; When the flexure strip return, be about to busbar and be pressed on the brace head antetheca.Certainly, the afterbody of brace inserts electric power transmission network by diode, junction block etc.
The other end of flexure strip hooks the antetheca of accommodation aperture, can guarantee further that flexure strip has enough thrusts and can not be shifted.
In the design of busbar jockey, what need most consideration is reliability and the convenience that connects, and as connecting with welding or screw, though can guarantee bonding strength, operation is trouble too; If general contact connects, then reliability is not enough.The present invention utilizes flexure strip to compress and realizes being electrically connected, utilized lever principle again simultaneously, so flexure strip can be provided with sizable elastic strength, satisfies the reliability that connects; On the other hand, operation of the present invention also is very simple.
The present invention has only two main parts size, and pegging graft each other cooperates, and has good interchangeability, safeguards also very simple and convenient.

Embodiment
Referring to Fig. 1 and Fig. 2 and Fig. 3, metal connecting sheet 3 heads are provided with first through hole 4.Metal connecting sheet 3 comprises head antetheca 14, head rear wall 1, tail end 2 and support end 10
Referring to Fig. 4 and Fig. 5, flexure strip 5 short ends have crotch 13, and long end has second through hole 6.
Referring to Fig. 6 and Fig. 7, first through hole 4 that the long end of flexure strip 5 passes metal connecting sheet 3 stretches into metal connecting sheet 3 heads, can not continue to insert until flexure strip 5, the nose circle of flexure strip 5 is conflicted on the metal connecting sheet 3, at this moment the long end of flexure strip 5 is pressed on the head antetheca 14 of metal connecting sheet 3, as can be seen from Figure, crotch 13 on the flexure strip 5 has caught on the antetheca of accommodation aperture, when using screwdriver 9 to pass second through hole, 6 downward exerting oneself, but the stressed flexure strip 5 of flexure strip 5 long ends does not produce whole displacement, and metal connecting sheet 3 can be not stressed.
The head of metal connecting sheet 3 is placed into after the accommodation aperture 12, and the nose circle of flexure strip 5 is close to accommodation aperture bottom 11, and metal connecting sheet 3 head rear walls 1 are close to the rear wall of accommodation aperture 12, and the tail end 2 of metal connecting sheet 3 is fixedlyed connected with box body 7 riveteds near box body 7.
The nose circle of flexure strip 5 can be close to accommodation aperture bottom 11, and metal connecting sheet 3 head rear walls 1 can be close to the rear wall of accommodation aperture 12, all can realize technical scheme of the present invention.
Referring to Fig. 7 and Fig. 8, before busbar 8 is inserted, earlier with second through hole 6 of screwdriver 9 by flexure strip 5, be against on the support end 10 of metal connecting sheet 3, move screwdriver 9 then in the direction of arrow B, at this moment the long end of flexure strip 5 is stressed descending, after moving, screwdriver 9 can not make metal connecting sheet 3 produce displacement downwards, therefore has only flexure strip 5 by drop-down, flexure strip 5 short ends do not produce displacement, flexure strip 5 space occurs with the head antetheca 14 of metal connecting sheet 3, and busbar 8 inserts in this space in the direction of arrow A.Unclamp screwdriver 9 then, screwdriver 9 is withdrawed from by the arrow C direction from accommodation aperture 12, at this moment the long end of flexure strip 5 is no longer stressed, resilience occurs, thereby clamps busbar 8.
