Abstract
The utility model relates to a wiring box fixed on a solar battery, which comprises an insulation box body (2), a conductor connecting part (4), a diode (5), a conducting wire (1) and a pressing block (3); an extension segment (3a) is arranged outside the pressing block; the length of the pressing block is increased by at least 10 mm and does not surpass the edge of the insulation box body; a wire pressing groove (2a) of the insulation box body corresponding to the outward extension part is identical with that of the pressing block; a radial ring-shaped strengthening rib (7) and an axial strip-shaped strengthening rib (6) are evenly arranged on the inner hole surface of the wire pressing grooves of the pressing block and the insulation box body; the axial strengthening rib is divided into two segments which are arranged in a staggered manner; and a gap between conductor connecting part and the inner wall of the insulation box body is at least 5 mm. The utility model enlarges the sealing and encapsulating space of the wiring box, thereby greatly enhancing the sealing effect, improves the traction resistance and a twisting resistance of the wire pressing groove of the wiring box, and effectively avoids the formation of a steam channel.
Description
Technical field
The utility model relates to a kind of terminal box, especially a kind of terminal box that is used for solar cell.
Background technology
Existing solar power generation adopts the matrix compound mode will organize solar module more, and to link together conversion of solar energy be electric energy, every group of solar module all is fixed with a terminal box and is used for electric energy transmitting, and terminal box other parts of connected system is more finally formed the whole generating system.Because the design of the structure of terminal box will directly cause the efficient of electric energy transmitting, and the terminal box on the market to be simple box body mostly seal, cause the function of aspects such as integral waterproofing gas, anti-external force barely satisfactory.
The utility model content
The purpose of this utility model is exactly in order to solve the conventional electrical connectors simple seal, causes the goodish problem of function of aspects such as integral waterproofing gas, anti-external force, a kind of improved terminal box of proposition.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of terminal box that is used for solar cell, comprise insulation box body, conductor adapting piece, diode, lead and briquetting, one end of two conductor adapting pieces is fixed on the insulation box body, the center contact of two conductor adapting pieces is welded with diode, the other end of two conductor adapting pieces respectively is welded with lead, the pressuring line groove that lead passes the insulation box body outwards connects, and cooperates with the insulation box body by briquetting lead is compressed; Described briquetting arranged outside has extension, its at least 10 millimeters of length increase and be no more than insulation box body edge, and the corresponding overhanging position of the pressuring line groove of insulation box body is identical with briquetting.
The pressuring line groove inner hole surface of described briquetting and insulation box body evenly is provided with annular radial reinforcement and axial strip reinforcement, and shaft orientation reinforcing rib divides two sections and the setting of staggering.
At least 5 millimeters of the inwall spacings of described conductor adapting piece and insulation box body.
The beneficial effects of the utility model are to have enlarged terminal box sealing encapsulating space, make sealing effectiveness strengthen greatly, have improved the anti-tractive effort and the twisting resistance of terminal box pressuring line groove, and have prevented the formation of aqueous vapor passage effectively.
