Meanwhile, the photovoltaic junction box is internally provided with a power management module, the power management module is connected with two photovoltaic cables, the other ends of the photovoltaic cables extend out of the photovoltaic junction box, the upper box body and the lower box body are connected together through an ultrasonic welding method, and the photovoltaic cables are connected with the power management module through an intermediate-frequency welding method. The photovoltaic junction box has the advantages of smaller contact resistance and smaller hidden risks.
Description
Technical field
The utility model relates to photovoltaic module technical field, especially relates to a kind of photovoltaic junction box.
Background technology
Photovoltaic junction box is a vitals of solar photovoltaic assembly.The at present connection of photovoltaic cable is undertaken by scolding tin or crimping mode, thereby less and easily occur rosin joint for the contact area that connects, and then contact resistance is larger., because tin material is subject to temperatures involved, melt meanwhile, thereby there is various hidden danger.And, cable in terminal box with outlet on one side, the waste while causing cable in the construction and installation of PV assembly fixedly.
Utility model content
The purpose of this utility model is to provide a kind of photovoltaic junction box, and it is less that it has contact resistance, and the less feature of hidden danger.The feature of comparatively saving when further, it also has construction.
The technical scheme that the utility model adopts is: photovoltaic junction box, comprise the upper cartridge body and the lower box body that link together, and this upper cartridge body is provided with lid, simultaneously, in this photovoltaic junction box, be provided with power management module, this power management module is connected with 2 photovoltaic cables, and this photovoltaic cable other end stretches out this photovoltaic junction box, described upper cartridge body and lower box body link together by ultrasonic bonding mode, and described photovoltaic cable is realized and being connected with this power management module by the mode of medium frequency welding.
Described power management module is fixed in this photovoltaic junction box by the mode of hot melt.
Described upper cartridge body or lower box body are provided with hole for injecting glue, in this photovoltaic junction box, are filled with heat conductive silica gel.
Described 2 photovoltaic cables stretch out this photovoltaic junction box from the relative both sides of this photovoltaic junction box respectively.
The outer surface of described upper cartridge body and/or lower box body is provided with radiating fin.
Described upper cartridge body and/or lower box body are provided with heat radiation honeycomb.
The advantage that the utility model has is: 1, contact resistance is less, and hidden danger is less.Photovoltaic junction box of the present utility model is for the connected mode of upper cartridge body and lower box body, and the connected mode of photovoltaic cable and power management module is improved.That is, adopt respectively the mode of ultrasonic bonding and medium frequency welding to connect, thereby increased the contact area connecting, meanwhile, avoided the use of tin material, thus safer while using.While 2, constructing, comparatively save.2 photovoltaic cables of the present utility model stretch out from the relative both sides of this photovoltaic junction box, thus when construction without fixed cable respectively, comparatively save.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the perspective exploded view of the photovoltaic junction box of embodiment of the present utility model;
Fig. 2 is the upward view of the photovoltaic junction box of embodiment of the present utility model.

Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: photovoltaic junction box, comprise the upper cartridge body 10 and the lower box body 20 that link together, and this upper cartridge body 10 is provided with lid 30.Meanwhile, be provided with power management module 40 in this photovoltaic junction box, this power management module 40 is connected with 2 photovoltaic cables 50, and these photovoltaic cable 50 other ends stretch out this photovoltaic junction box.Further say, this upper cartridge body 10 and lower box body 20 link together by ultrasonic bonding mode.That is, before welding, ultrasonic wire welding is placed in the joint portion at this upper cartridge body 10 and lower box body 20.Meanwhile, this photovoltaic cable 50 is realized and being connected with this power management module 40 by the mode of medium frequency welding.Like this, reduced the contact resistance of photovoltaic junction box, and safer while using.
Optimize:
This power management module 40 is fixed in this photovoltaic junction box by the mode of hot melt.Like this, make comparatively firm being fixed in this photovoltaic junction box of this power management module 40.
This upper cartridge body 10 or this lower box body 20 are provided with hole for injecting glue (not shown on figure), are filled with heat conductive silica gel (not shown on figure) in this photovoltaic junction box.Like this, further increased the radiating effect of power management module 40.
These 2 photovoltaic cables 50, respectively from the relative both sides of this photovoltaic junction box, such as left side and right side, stretch out this photovoltaic junction box.Like this, when connection construction, comparatively save.
The outer surface of this upper cartridge body 10 and/or lower box body 20 is provided with radiating fin 60, and this upper cartridge body 10 and/or lower box body 20 are provided with heat radiation honeycomb 70.Like this, further increased the radiating effect of this photovoltaic junction box.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification 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 utility model.
