Abstract
The utility model relates to an improved solar photovoltaic wiring box comprising a box bottom and a box cover arranged on the box bottom. A diode clamping-connecting structure is arranged in the box bottom and comprises a bracket and a tube support spring arranged in the bracket, a diode is clamped between the side edge of the bracket and the clamping side of the tube support spring, on the side edge of the bracket, inner-convex grooves are respectively arranged at a pin of the diode, and the pin of the diode is tightly clamped between the clamping edge of the tube support spring and the inner-convex grooves of the bracket. According to the improved solar photovoltaic wiring box, due to the arrangement of the inner-convex grooves, the contact area between the pin of the diode and the bracket is improved, and the contact resistance is reduced.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box.
Background technology
The photovoltaic terminal box is provided with and is used for the interface arrangment of clamping diode; Interface arrangment has and is used through tube stay spring and support; Support is arranged on tube stay spring top, and the pin of diode is inserted between tube stay spring and the support through the jack on the support and is held, in the prior art; Contact area is less between diode and the support, and then contact resistance is bigger.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of improved photovoltaic terminal box that can improve contact area between diode and the support.
The technical scheme that the utility model solves its technical problem is:
A kind of improved photovoltaic terminal box; Comprise at the bottom of the box be arranged at the bottom of the box on lid; Be provided with the diode interface arrangment at the bottom of the described box, described diode interface arrangment comprises support and the tube stay spring that is arranged in the support, and clamping has diode between the contained side of the side of described support and tube stay spring; The side of described support is provided with interior tongue respectively at the Pin locations place of diode, and the pin of described diode is clamped between the interior tongue of contained side and support of tube stay spring.
As improvement, the contact-making surface of the pin of interior tongue and diode is a cambered surface.
Place in support and the clamping of tube stay spring; Interior tongue is set on the side of support, is convex on the inner surface of support promptly, when then the pin of diode is inserted between interior tongue and the tube stay spring; Pin tightly is clamped between support and the tube stay spring; Not only increase chucking power, and increased the inner surface of support and the contact area between the pin, reduced contact resistance.When the contact-making surface of interior tongue was cambered surface, contact area was bigger, and contact resistance is littler.
The beneficial effect of the utility model is: the utility model has increased the pin of diode and the contact area between the support through the setting of interior tongue, has reduced contact resistance.
Description of drawings
Fig. 1 is the structural representation of the support of the utility model.
Fig. 2 is the support of the utility model and the sectional structure sketch map of tube stay spring.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
A kind of improved photovoltaic terminal box; Comprise at the bottom of the box be arranged at the bottom of the box on lid; Be provided with the diode interface arrangment at the bottom of the described box; Like Fig. 1, shown in 2, described diode interface arrangment comprises support 1 and the tube stay spring 4 that is arranged in the support, and clamping has diode between the contained side of the side of support and tube stay spring; The side of described support is tongue 3 in the Pin locations place of diode is provided with respectively, and the pin 2 of diode is clamped between tube stay spring 4 contained sides and the support 1 interior tongue 3.In addition, be cambered surface also with the contact-making surface of interior tongue 3 and the pin of diode.
Place in support and the clamping of tube stay spring; Tongue 3 in being provided with on the side of support, promptly to be provided with on the inner surface of position of diode pin be convex to support, in then the pin of diode is inserted between tongue and the tube stay spring time; Pin 2 tightly is clamped between support and the tube stay spring; Not only increase chucking power, and increased the inner surface of support and the contact area between the pin, reduced contact resistance.When the contact-making surface of interior tongue was cambered surface, contact area was bigger, and contact resistance is littler.
Claims (2)
1. improved photovoltaic terminal box; Comprise at the bottom of the box be arranged at the bottom of the box on lid; Be provided with the diode interface arrangment at the bottom of the described box; Described diode interface arrangment comprises support and the tube stay spring that is arranged in the support; Clamping has diode between the contained side of the side of described support and tube stay spring, it is characterized in that: the side of described support is provided with interior tongue respectively at the Pin locations place of diode, and the pin of described diode is clamped between the interior tongue of contained side and support of tube stay spring.
