Abstract

The utility model discloses a photovoltaic assembly terminal box, which comprises a box body, a box cover, a copper bridge, a triangular spring sheet, a diode, a copper joint and a connector, wherein the copper bridge, the triangular spring sheet, the diode, the copper joint and the connector are arranged in the box body, the triangular spring sheet is blocked and connected with the copper bridge in an external insertion manner so that the spring sheet is blocked on the copper bridge, the structural design of the triangular spring sheet is special so that the visual effect is more attractive and has a linearity feel, a bus bar can be clamped more tightly, the power consumption of assemblies is reduced, the utilization ratio of solar energy is improved, and the service life of the terminal box is prolonged; the diode is fixed on the copper bridge through an internal spring sheet in the copper bridge and an open slot on the copper bridge so that the copper bridge and the diode have a larger contact area and a firmer contact; and the copper joint is fixedly screwed and connected with the copper bridge. The copper joint is connected with the connector in an embedding manner so that the current consumption is reduced better, and the utilization ratio of the solar energy is improved; and a box cover sealing ring is embedded in the box cover so that the sealing ring is fixed in the box cover better, and the tightness of the whole box becomes the best.

Description

The photovoltaic module terminal box

Technical field

The utility model relates to a kind of photovoltaic interface unit, especially a kind of photovoltaic module terminal box.

Background technology

The structure more complicated of photovoltaic module terminal box is in the market installed also inconvenience, and the inner overall connection resistance of terminal box is big, the loss height.

The utility model content

The utility model technical issues that need to address provide a kind of simple in structure, easy for installation, and contact resistance is little, photovoltaic module terminal box low in energy consumption.

For addressing the above problem, technical solution adopted in the utility model is: a kind of photovoltaic module terminal box, comprise box body and lid, lid and box body adopt and are tightly connected, also be provided with the lid sealing ring on the lid, the sealing circle embeds in the seal groove of lid, the copper bridge is set in the box body, the triangle shell fragment, diode, copper sleeve and connector, its intermediate cam shell fragment and copper bridge are clamping, diode is fixed in the groove of opening on the two bronze medal bridges, simultaneously by the bridge inner shrapnel chucking that is fixed on copper bridge inside, copper sleeve one end is fastened on the copper bridge by screw, the other end embeds with connector and is connected, and connector is fixed on the box body, and the clamping between described triangle shell fragment and the copper bridge is the outside plug type clamping.

Adopt the beneficial effect that technique scheme produced to be: this novel triangle shell fragment and copper bridge use the outside plug type clamping, shell fragment is stuck on the copper bridge, unique triangle elastic piece structure design, visual effect is more attractive in appearance, have linear sense, and can better clamp busbar, reduce the power consumption of assembly, improve solar energy utilization ratio, increase the service life of terminal box; Diode is fixed on the copper bridge diode by the bridge inner shrapnel of copper bridge inside and the fluting on the copper bridge, not only makes the contact-making surface of copper bridge and diode wider, and contact is tighter; Copper sleeve and copper bridge utilize screw tightening to fix.Adopt embedded the connection with connector, better reduce the loss of electric current, improve solar energy utilization rate; The lid sealing ring uses embedded connection in the lid, and sealing ring is fixed in the lid, also makes the sealing of whole box reach best; This new arrangement box overall structure is simple, and spare and accessory parts are few, and is easy for installation, is electrically connected reliably, and the terminal box overall electrical resistance is low, and loss is little, the efficient height.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail: this novel box body 5 and lid 6 of comprising, lid and box body adopt and are tightly connected, as shown in Figure 1, this novel copper bridge 1 that is installed in the box body that also comprises, triangle shell fragment 3, diode 4, copper sleeve 9 and connector 8, this novel intermediate cam shell fragment is connected with the copper bridge: use the outside plug type snap fit, unique triangle elastic piece structure design, visual effect is more attractive in appearance, has linear sense, and can better clamp busbar, reduce the power consumption of assembly, improve solar energy utilization ratio, increase the service life of terminal box.The inner bridge inner shrapnel of installing of copper bridge by the elastic force of bridge inner shrapnel and the fluting on the copper bridge, is fixed on the copper bridge diode, and duplicate protection connects; The unique construction of bridge inner shrapnel can make the elastic force of bridge inner shrapnel reach maximization, more can make elastic force keep the longer time, the chucking diode; Fluting on the copper bridge is better fixed diode on the one hand, makes the contact-making surface of copper bridge and diode wider on the other hand, thereby reduces the power consumption of whole box and even assembly; Copper sleeve one end utilizes screw tightening to be fixed on the copper bridge, and the other end embeds with connector and is connected, and better reduces the loss of electric current, improves solar energy utilization rate.

As shown in Figure 2, also be provided with lid sealing ring 7 on the described lid, the sealing circle embeds in the seal groove of lid.Lid sealing ring in the lid adopts embedded connection, sealing ring is fixed in the lid, also make the sealing of whole box reach best, box body also uses embedded the connection with lid simultaneously, fixing of 6 points, lid is coupled in the box body, has both guaranteed the sealing of whole box, improved the service life of whole box again.

This new arrangement box overall structure is small and exquisite, and spare and accessory parts are few, and is easy for installation, and maintenance is easy, and whole nothing welding meets environmental protection requirement, and mechanical connection is firm, guarantees its fail safe.Terminal box integral heat sink performance is good, can prevent effectively that the terminal box generation is overheated and cause assembly to have an accident, and has more useful life.

Terminal box is in installation process, because structural advantage, assembly producer is easy to operate, and is less demanding to employee's operant level, can effectively improve the operating efficiency of assembly producer.The internal electric structure is firm, reduces accident rate, improves the fail safe of photovoltaic module greatly.Under various rugged environments, for example snow greasy weather or the like, can both operate normally.
