1, poor thermal conductivity: because box body and upper cover body are to make with glass fibre filled makrolon material, its poor thermal conductivity easily causes terminal box internal electron damage parts.

2, failure rate height: because this common junction box of solar module is to be fixed together by locator card zygostyle on the upper cover plate and the involutory blocking in the suitable hole of locator card on the box body, and the locator card zygostyle on the upper cover plate easily ruptures because of dismounting box body and upper cover plate, when one of them locator card zygostyle fracture, this terminal box promptly can't reach and effectively cover effect, so, this common junction box of solar module failure rate height.

Summary of the invention

In view of the foregoing, in order to improve the common high problem of junction box of solar module poor thermal conductivity, failure rate at present, the purpose of this utility model provides a kind of aluminium alloy junction box of solar module.

For achieving the above object, the utility model by the following technical solutions: a kind of aluminium alloy junction box of solar module is characterized in that: this terminal box is to make with aluminium alloy.

This aluminium alloy junction box of solar module comprises:

One box body, this box body are provided with radiating part, first draw-in groove, second draw-in groove, positioning runner, locking hole and wire connecting portion;

One lid, this lid are provided with involutory positioning convex portion of chute and perforation, and involutory positioning convex portion of this chute and the set positioning runner of box body are involutory, make lid promote to be covered on the box body along the set positioning runner of box body, and are difficult for producing fault; When lid was covered on box body, the locking hole of described perforation and box body was involutory, and is promptly can locking part that it is sealed fixing;

One groups of holders, this groups of holders is provided with first and second stake body, and this first and second stake body blocking respectively is fixed in first, second set draw-in groove of box body, and with locking part that first and second stake body and set first and second draw-in groove of box body is sealed, and this groups of holders for fixing electronic component thereon;

Described box body, lid and groups of holders are to make with aluminium alloy, can effectively improve radiating effect, and when box body combined with lid, its edge imposed adhesion body involution.

The utility model has the advantages that: thermal conductivity is good, failure rate is low.
