Abstract
Disclosed in the utility model is a photovoltaic junction box conductor comprising a body. The body includes a flat base plate; the two sides of the front portion of the base plate bend upwardly by 90 degrees to form front folding edges; the upper side of the rear portion of the base plate is connected with a bus bar; two sides of the rear portion of the base plate bend upwardly by 90 degrees to form rear folding edges. Meanwhile, the conductor includes a spring sheet; the front end of the spring sheet is hinged to the front portions of the rear folding edges; the middle portion of the spring sheet protrudes downwardly; and the two sides of the rear portion of the spring sheet are provided with clamp blocks. The rear portions of the rear folding edges are provided with bayonets with upward openings; and the bayonets match the clamp blocks. According to the scheme, the provided conductor has advantages of realizing convenient connection, minimizing an assembly reject ratio, enabling connection between the bus bar and the conductor to be reliable, and avoiding using the tin material.
Description
Technical field
The present invention relates to photovoltaic accessory technical field, especially relate to a kind of photovoltaic junction box electric conductor.
Background technology
Photovoltaic junction box is accessory conventional in photovoltaic industry.Conventionally, this photovoltaic junction box comprises box body, in this box body, is provided with electric conductor, and this electric conductor rear portion is provided with that busbar, middle part are provided with diode, front end is connected with cable.Wherein, the connection of this electric conductor and this busbar is many to be connected by scolding tin, thereby is easy to occur rosin joint, sealing-off phenomenon between this electric conductor and this busbar, and then the bonding strength of the two is lower.Meanwhile, the connection of this electric conductor and this busbar is comparatively loaded down with trivial details, and has wasted a large amount of tin materials.
Summary of the invention
The object of this invention is to provide a kind of photovoltaic junction box electric conductor, it has with the connection of busbar comparatively firm, and connects simply the feature that can save tin material.
The technical solution adopted in the present invention is: photovoltaic junction box electric conductor, comprise body, this body comprises smooth base plate, thereby this base plate front part sides all upwards 90 ° of bendings be formed with front flanging, and the rear portion upside of this base plate is used for connecting busbar, thereby the rear portion of described base plate two avris all upwards 90 ° of bendings be formed with rear flanging, simultaneously, this photovoltaic junction box electric conductor includes shell fragment, the front end of this shell fragment is hinged in the front portion of this rear flanging, and protrude downwards at this shell fragment middle part, and, the both sides, rear portion of this shell fragment are provided with fixture block, the rear portion of this rear flanging is provided with the bayonet socket of opening upwards, this bayonet socket and this fixture block match.
The rear portion of described shell fragment is provided with pressing plate.
The advantage that the present invention has is: 1, easy to connect, after busbar is put into below shell fragment, the head that pushes shrapnel directly clamps, more for convenience.2, after adopting shell fragment to connect, the contact resistance between busbar and electric conductor obviously reduces, and can promote photovoltaic module efficiency.3, adopt shell fragment to connect, can increase the bonding strength between busbar and electric conductor, the fraction defective of assembly is dropped to minimum.4, use shell fragment connected mode, make to be connected more reliably between busbar and electric conductor, and in the time of product work, terminal box can reduce heating temp.5, avoid using tin material, reduced the use cost of photovoltaic junction box.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
In figure: 10, body, 11, base plate, 12, front flanging, 13, rear flanging, 131, bayonet socket; 20, shell fragment, 21, fixture block, 22, pressing plate.
Embodiment
Embodiment, as shown in Figure 1: photovoltaic junction box electric conductor, comprises body 10.This body 10 comprises smooth base plate 11, thus these base plate 11 front part sides all upwards 90 ° of bendings be formed with front flanging 12, and the rear portion upside of this base plate 11 is used for connecting busbar.That is to say, this busbar is positioned over the rear portion upside of this base plate 11.Concretely, thus rear portion two avris of this base plate 11 all upwards 90 ° of bendings be formed with rear flanging 13.Meanwhile, this photovoltaic junction box electric conductor includes shell fragment 20, and the front end of this shell fragment 20 is hinged in the front portion of this rear flanging 13, and protrude downwards at these shell fragment 20 middle parts.Such as, this shell fragment 20 can be " U " font, semicircle, " V " font.And the both sides, rear portion of this shell fragment 20 are provided with fixture block 21, the rear portion of this rear flanging 13 is provided with the bayonet socket 131 of opening upwards, and this bayonet socket 131 and this fixture block 21 match.; this busbar is positioned over to the rear portion upside of this base plate 11; then press this shell fragment 20 downwards; the fixture block 21 at the rear portion of this shell fragment 20 is snapped in this bayonet socket 131; thereby the protrusion position, middle part of this shell fragment 20 being pressed on busbar tightly, realizes the firm connection of this busbar and this electric conductor.Such connected mode is for soldering, more for convenience.And the contact resistance between this busbar and this electric conductor obviously reduces, and can promote photovoltaic module efficiency.And such connected mode can increase the bonding strength between this busbar and electric conductor, the fraction defective of assembly is dropped to minimum.Certainly, such connected mode has been saved tin material.
Optimize, the rear portion of this shell fragment 20 is provided with pressing plate 22.Like this, be convenient to this shell fragment 20 to apply with downward power.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
