Abstract
The utility model relates to a low-contact resistance photovoltaic junction box. The low-contact resistance photovoltaic junction box comprises a box body and a photovoltaic component arranged in the box body; the lower end of the box body is connected with a positive pole cable and a negative pole cable respectively; the photovoltaic component includes metal supports which are electrically connected with the cables, and diodes; the lower ends of the metal supports are provided with connection ends used for connecting the cables; two screw holes through which the cables can pass are formed in the lower end of the box body; cable pressing blocks are arranged between the screw holes and the metal supports; the cable pressing blocks and the box body are integrally molded; operation holes which are corresponding to the connection ends of the metal supports are formed at the bottom of the box body; and the cables pass through the screw holes and the cable pressing blocks, and then, are connected with the connection ends of the metal supports. According to the low-contact resistance photovoltaic junction box of the utility model, the cable pressing blocks and the box body are arranged integrally, and the operation holes are formed at the bottom of the box body, and therefore, related metal components for mounting the cables can be decreased, and contact resistance can be reduced, and at the same time, connection of the cables to the metal supports will not be affected, and convenient installation can be realized.
Description
(1) technical field
The utility model relates to a kind of photovoltaic junction box.
(2) background technology
Photovoltaic junction box includes box body and is arranged on the photovoltaic module in box body, positive pole and the negative electricity cable of photovoltaic module electrical connection box body lower end, along with the development trend of photovoltaic junction box, require contact resistance lower, the performance of terminal box is better, in prior art, cable is generally by welding or screw fastening mode connection metal support, and then compress cable by cable briquetting, be cable briquetting and box body split setting, when installation, cable welding or screw fastening need to be compressed to operation after metallic support more again, the metal parts connecting is like this more, cause contact resistance higher.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of contact resistance photovoltaic junction box low and easier for installation.
The technical scheme in the invention for solving the technical problem is:
A kind of photovoltaic junction box of low contact resistance, comprise box body and be arranged on the photovoltaic module in box body, box body lower end is connected with respectively positive pole and negative electricity cable, described photovoltaic module comprises the metallic support and the diode that are electrically connected cable, metallic support lower end is provided for the link of connecting cable, the lower end of box body arranges the screw that two power supply cables wear, it is characterized in that: between described screw and metallic support, be provided with and the integrated cable briquetting of box body, the link position of the corresponding metallic support in box body bottom offers handle hole, described cable wears screw and cable briquetting, and connect the link of described metallic support.
As preferably, metallic support arranges on metallic support seat, upper surface next-door neighbour's metallic support seat of described cable briquetting.
As preferably, link comprises U-shaped intermediate plate, and the wire in described cable clamps by U-shaped intermediate plate.
By one-body molded to cable briquetting and box body, in setting operation hole, box body bottom, cable wears after screw and cable briquetting, by handle hole position, the link of metallic support being operated, by cable connection metal support.Like this, reduced the associated metal parts of installing cables line, and the cable briquetting being wholely set also there will not be the phenomenons such as loose or dislocation.The link of metallic support is set to U-shaped intermediate plate, and after cable stretches in U-shaped intermediate plate, as long as it is clamped in handle hole by instrument, operation is very easy, and contact resistance reduces.
The beneficial effects of the utility model are: the utility model is wholely set cable briquetting and box body, and offer handle hole in box body bottom, reduced the associated metal parts of installing cables line, reduced contact resistance, do not affect cable connection metal support simultaneously, easy for installation.
(4) brief description of the drawings
Fig. 1 is structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of photovoltaic junction box of low contact resistance, comprise box body 2 and be arranged on the photovoltaic module in box body, box body lower end is connected with respectively positive pole and negative electricity cable 5, photovoltaic module comprises the metallic support 1 and the diode that are electrically connected cable, metallic support lower end is provided for the link 7 of connecting cable, the lower end of box body arranges the screw that two power supply cables wear, between described screw and metallic support, be respectively arranged with and the integrated cable briquetting 3 of box body, the link position of the corresponding metallic support in box body bottom offers respectively handle hole 4, cable wears screw and cable briquetting 3, and connect the link 7 of described metallic support.Metallic support 1 arranges on metallic support seat, upper surface next-door neighbour's metallic support seat of described cable briquetting 3.
Link 7 comprises U-shaped intermediate plate, and the wire in cable clamps by U-shaped intermediate plate.
By one-body molded to cable briquetting 3 and box body 2, in setting operation hole 4, box body bottom, cable wears after screw and cable briquetting, by handle hole position, the link 7 to metallic support operates, by cable connection metal support.Like this, reduced the associated metal parts of installing cables line, and the cable briquetting being wholely set also there will not be the phenomenons such as loose or dislocation.The link of metallic support is set to U-shaped intermediate plate, and after cable stretches in U-shaped intermediate plate, as long as it is clamped in handle hole by instrument, operation is very easy, and contact resistance reduces.
The utility model is wholely set cable briquetting and box body, and offers handle hole in box body bottom, has reduced the associated metal parts of installing cables line, has reduced contact resistance, does not affect cable connection metal support simultaneously, easy for installation.
