Description
Technical field
The utility model relates to the photovoltaic generating system field, specifically, specially refers to a kind of modified model direct current junction box wiring construction.
Background technology
The junction box is connection box again, generally is used for outdoor plugging into during circuit, can also conveniently overhaul in waterproof, often uses in weak current engineering.The junction box is that lead is put to box house when construction in the prior art, lead is connected on the terminal in the casing again, with screwdriver line is fixed.The shortcoming of this form of construction work is, the installation procedure complexity, and installation steps are loaded down with trivial details, so installation effectiveness is also comparatively low.
The utility model content
The purpose of this utility model is to provide a kind of modified model direct current junction box wiring construction, by adopting novel structure, under the prerequisite that guarantees structural strength, optimized installation procedure, installation steps have been simplified, improve installation effectiveness, thereby overcome the deficiency in the conventional art, realized the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of modified model direct current junction box wiring construction, it comprises casing, dc circuit breaker, permanent joint and water joint, the inside of described casing is equipped with dc circuit breaker, the bottom of casing is equipped with some permanent joints, described dc circuit breaker is provided with binding post, described binding post is connected and fixed an end of joint, and the other end of permanent joint connects water joint; Described permanent joint and water joint include positive joint and negative joint, and dc circuit breaker is provided with corresponding positive binding post and negative tab terminal, and positive joint is connected positive binding post and negative tab terminal with negative joint respectively by cable.
In an embodiment of the present utility model, the label of negative or positive electrode is carved with on the surface of described positive binding post, negative tab terminal, positive joint and negative joint.
In an embodiment of the present utility model, described casing adopts the integral type shaped structure.
The beneficial effects of the utility model are: simple in structure, design ingeniously, and by adopting novel structure, under the prerequisite that guarantees structural strength, optimized installation procedure, simplified installation steps, improved installation effectiveness.
Description of drawings
Fig. 1 is the schematic diagram of a kind of modified model direct current junction box wiring construction described in the utility model.
Embodiment
