Little, excessively concentration and the photovoltaic module caused positioned at the same area heating is concentrated, the problem that local temperature rise is too high；The opposing party
Face, neighboring diode is separated in the both sides of above-mentioned straight line, also be effectively prevent when some diode as hot spot effect is sent out
When hot, remaining diode is still operated in reverse state, and its leakage current is increased dramatically, causes the problem of temperature rise.In conjunction with above-mentioned
, working of plastics, the aging speed of casting glue contacted with photovoltaic module, and photovoltaic module also can be greatly reduced on the whole at 2 points
The oxidation rate of middle electric-conductor, extends its overall using effect and service life.
In sum, this case can be prevented effectively from the problems such as local temperature is too high, radiating is uneven on the whole, effectively be lifted
The overall using effect of equipment extension device whole service life.
The n-1 diode 2 is arranged and perpendicular with electric conductor 1 in the same direction.
The both sides of the leading foot 10 are provided with capillary groove.
Representative explanation is done as embodiment with n=4 below：
The photovoltaic module includes four electric conductors 1 being parallel to each other and three diodes 2 being parallel to each other, the conduction
Body 1 is divided into electric conductor 1, electric conductor 2 12, electric conductor 3 13 and electric conductor 4 14, and the diode 2 is divided into two
Pole pipe 1, diode 2 22 and diode 3 23；
The electric conductor 1 and electric conductor 4 14 are located at the same side of the straight line, the electric conductor 2 12 and electric conductor
3 13 the same sides for being located at the straight line, the electric conductor 1 and electric conductor 2 12 are located at the both sides of the straight line；
The diode 1 and diode 3 23 are located at the same side and diode 1 and the diode two of the straight line
22 both sides for being located at the straight line；
3 points of the pin is long pin 31 and short pin 32, and the short pin 32 is in in-line, and the long pin 31 is in L
Font, the diode 1 are connected with electric conductor 1 by short pin 32 and are connected with electric conductor 2 12 by long pin 31
Connect；The both sides of the diode 2 22 are connected with electric conductor 2 12 and electric conductor 3 13 respectively by two short pins 32；Described two
Pole pipe 3 23 is connected with electric conductor 3 13 by long pin 31 and is connected with electric conductor 4 14 by short pin 32.So so that
While neighboring diode is located at the both sides of above-mentioned straight line so that the spacing between neighboring diode is equal, so as to effectively guarantee
Heat dissipation uniformity, and then the too high problem of the temperature rise caused because concentrating heating is avoided, effectively extend photovoltaic module
Service life, improve the using effect of photovoltaic module.
People have found after use, due to diode after heating most of heat by by with leading that its negative pole is connected
Electric body guides diffusion, while must have the negative pole of in above-mentioned in three diodes by long pin and corresponding electric conductor
It is connected（Reason is that three diodes are sequentially connected in series）；Therefore, the radiating efficiency of the diode significantly will be less than other diodes,
So as to significantly reduce the using effect and service life of the diode；And cannot be carried out after impaired individually more due to diode
Change, therefore, this is also significantly reduced the using effect and service life of photovoltaic module on the whole.In this regard, this case is also from each
The radiating efficiency of diode, heat dissipation uniformity are angularly set out and have made following improvement：
The negative pole of the diode 1 is connected on electric conductor 1 by short pin 32, the diode 2 22 negative
Pole is connected on electric conductor 2 12 by short pin 32, and the negative pole of the diode 3 23 is connected to electric conductor by long pin 31
On 3 13；
The electric conductor 3 13 is provided with extension board 130 away from the side of diode 2 22, offers on the extension board 130
The storage tank 131 of the L-shaped being adapted to long pin 31, the long pin 31 be contained in the storage tank 131 and with the appearance
Put groove 131 to be fixedly linked with forms such as welding.So as to effectively ensure that the uniformity in each diode radiating path, that is, it is prevented effectively from
The using effect and service life that diode three is caused less than other diodes because of radiating efficiency is far below other diodes
Problem, therefore, the optimal enforcement mode improves radiating efficiency, heat dissipation uniformity and the use of photovoltaic module on the whole
Effect, and effectively extend the overall service life of photovoltaic module.
The terminal box includes that box body 4, base and a pair of cables 5, the base are fixedly connected in box body 4 and are used for
The photovoltaic module is fixedly connected, and offers a pair on the side that n fairlead and box body 4 is offered on 4 top surface of the box body
Cable hole, the fairlead are corresponded and the top positioned at the leading foot 10 with leading foot 10, and the cable 5 is located in
