Description
Technical field
The utility model relates to the terminal box field, especially relates to a kind of solar battery connecting box.
Background technology
Solar cell obtains application more and more widely because of environmental protection.Usually the electric current that produces of solar cell is through busbar, and the terminal box through being connected with busbar again be transferred to follow-up usefulness electric line, and present busbar adopts usually the mode of fixed connection to be connected with terminal box.Adopt the fixed connection mode 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 fixedly connected with busbar, when any one goes wrong when busbar or terminal box, just must both all 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.
In addition, the general mode of directly welding that adopts of diode is fixed in the terminal box in the terminal box at present, and diode is damaged easily; It is just pretty troublesome when diode damages replacing; In order to overcome above-mentioned deficiency, Chinese utility model patent publication number CN201918382 discloses a kind of diode fixture of photovoltaic junction box, and it is through fixing elastic clip on the terminal box base; Two risers formation clamp ports are set outside elastic clip fixes diode; Its weak point is: its fixedly the elastic clip of diode be to be weldingly fixed on the base, opening upwards makes that its elastic force is not enough; Next is that structure is loaded down with trivial details.
Summary of the invention
The purpose of the utility model is to provide a kind of solar battery connecting box, and busbar, diode and terminal box are easy to connect and firm in this terminal box, and operating efficiency improves.
For this reason; The technical scheme of the utility model is such: solar battery connecting box, comprise box body, and arrangement of busbars is arranged in the box body, have the diode and the diode jockey of diode pin; Also comprise busbar jump ring, diode jump ring and at least 2 conducting brackets; Three parts before, during and after said conducting bracket divides, cross section is " ∏ " shape, front part sides has been worn symmetrical holes; Bottom of box body has projection, and the projection inboard has convexity, and when conducting bracket was fastened on Bottom of box body, the hole of conducting bracket cooperated with this convexity; Conducting bracket middle part is provided with accommodation aperture, has symmetric windows near the two sides of accommodation aperture rear wall; Said busbar jump ring is formed by a flexure strip bending, and its longitudinal section is trapezoidal, comprises long limit and minor face; One opening is arranged on the minor face; Both sides, long limit have symmetrical extension, and said busbar jump ring places accommodation aperture, and minor face and accommodation aperture antetheca are close to; Long limit and accommodation aperture rear wall are close to, and the extension on long limit cooperates with the breach of said accommodation aperture; The end face at conducting bracket rear portion and side intersection have at least one notch part; Said diode jump ring is formed by the flexure strip bending, comprises end face and side, and said side has jut and recess; The diode jump ring snaps in the conducting bracket rear portion, and its recess and said conducting bracket notch part are overlapped; The adjacent conductive support links to each other with diode, and the diode pin inserts the notch part of conducting bracket, and the recess of diode jump ring compresses the diode pin, makes said diode pin be close to conducting bracket.
Doing further to the utility model, improvement is: said conducting bracket is positioned on the shelves of Bottom of box body.
Preferred said conducting bracket rear portion has and stops end.
The diode jump ring of the utility model is preferably formed by a flexure strip bending.
Also can form for said diode jump ring is plugged together by two flexure strip bendings.Further improve and be: said flexure strip has an opening, and opening part has a plug or jack, matches with the jack or the plug of another flexure strip.
On the base of the utility model terminal box box body, all corresponding two projections of each conducting bracket and shelves, shape matches with conducting bracket.The projection inboard has convexity; The conducting bracket front part sides has a hole, and after conducting bracket was fastened on the base of terminal box, conducting bracket was between two projections; The convexity of projection is inserted in the hole of conducting bracket front part sides, make conducting bracket can not about, move forward and backward; Simultaneously, conducting bracket is placed on the shelves of Bottom of box body, and a fixed gap is arranged at itself and box body bottom, can make things convenient for busbar to penetrate.The middle part of conducting bracket has accommodation aperture; Have breach on the two sides near the accommodation aperture rear wall, the long sideband of busbar jump ring has the extension, after the busbar jump ring is placed the accommodation aperture of conducting bracket; The long limit and the accommodation aperture rear wall of busbar jump ring are close to; The breach on the accommodation aperture is passed in the extension on its long limit, makes the busbar jump ring be difficult for front and back, move up and down, thereby can't from accommodation aperture, pitch.During use,, make the antetheca of its minor face and accommodation aperture the space occur, busbar is stretched in this space as long as use screwdriver or similar means to prize the busbar jump ring; After Move tool makes busbar jump ring return, busbar will be pressed on the antetheca of conducting bracket accommodation aperture.
The diode jump ring of the utility model can be an end opening, is formed by a flexure strip bending, has an end of opening to compress to the centre diode jump ring; Make it can be inserted into vertical sectional shape from bottom to top in the conducting bracket of " ∏ " shape; Remove external force after the insertion, the resilience under elastic reaction of diode jump ring opening one end tightly is stuck in the conducting bracket; Simultaneously its not an end of opening receive the conducting bracket rear portion and stop stopping of end; Stopped by the plane of structure of conducting bracket above the diode jump ring, stopped by the terminal box base below, make its can't from up and down and the rear portion come off; After the diode jump ring was inserted into conducting bracket, the recess of diode jump ring side just in time was positioned at the gap portions of conducting bracket, has hidden the part breach.After two diode jump rings were installed in the adjacent conductive support respectively, tool using was pushed the recess of diode jump ring open, two pins of diode is inserted the notch part of above-mentioned two adjacent conductive supports respectively; Back off tool then; Diode jump ring return is pressed on the diode pin on two conducting brackets, and recess shape and the diode pin shape owing to the diode jump ring is complementary simultaneously; Make that the cooperation of diode jump ring and diode is tight, both are not easy to get loose.
The diode jump ring also can be to form by plugging together each other after two flexure strip bendings, and the structure of two flexure strips of employing can be so that the production assembling be convenient.
Can also have 2 juts and 2 corresponding recess on each side of diode jump ring, every side of conducting bracket can have two breach simultaneously, installs for two diodes arranged side by side.
Adopt after the technique scheme, only adopt three parts, promptly conducting bracket and diode jump ring and busbar jump ring just can be realized firmly connecting diode and busbar, and purpose easy to loading and unloading.
