Abstract

The utility model relates to a totally-enclosed junction box, comprising a connector positive pole and a connector negative pole, wherein the connector positive pole and the connector negative pole are connected through welding a diode, and the diode is sealed and wrapped by a protection sleeve. The totally-enclosed junction box enables the diode to be connected between the connector positive pole and the connector negative pole to form a low-power junction box, thereby being small in size and low in cost, not only playing an effect of protection, but also being suitable for mounting roof type photovoltaic assemblies under various environments.

Description

A kind of totally-enclosed terminal box
(1) technical field
The utility model relates to a kind of terminal box of new structure.
(2) background technology
Roof type photovoltaic electrification component of the prior art, power is generally less, adopts conventional terminal box, because the large inconvenience installation of volume, and cost is higher.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of novel totally enclosed type terminal box.
The technical scheme in the invention for solving the technical problem is:
A kind of totally-enclosed terminal box comprises the anodal and connector negative pole of connector, described connector anodal with the connector negative pole between be connected by welding a diode, and described diode outer seal sleeve is provided with protective sleeve.
As preferably, connector is anodal can be connected by the buckle connected mode with the connector negative pole.
Connector anodal with the connector negative pole between be connected by welding a diode; the diode outer seal sleeve is provided with protective sleeve; protective sleeve is carried out once injection moulding; diode is all sealed; then this diode and protective sleeve are equivalent to a low power photovoltaic junction box; it is overheated to prevent, photovoltaic electrification component is shielded.
The beneficial effects of the utility model are: the utility model connector anodal with the connector negative pole between be connected small-power terminal box of a diode formation; volume is little; cost is low, can play a protective role, and can be fit to again all-environment roof type photovoltaic module and install.
(4) description of 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 totally-enclosed terminal box comprises connector anodal 4 and connector negative pole 1, be connected by welding a diode 3 between described connector anodal 4 and the connector negative pole 1, and described diode outer seal sleeve is provided with protective sleeve 2.Connector anodal 4 can be connected by the buckle connected mode with connector negative pole 1.
Connector anodal with the connector negative pole between be connected by welding a diode 3; the diode outer seal sleeve is provided with protective sleeve; protective sleeve is carried out once injection moulding; diode is all sealed; then this diode and protective sleeve are equivalent to a low power photovoltaic junction box; it is overheated to prevent, photovoltaic electrification component is shielded.

Claims (2)

1. totally-enclosed terminal box comprises the anodal and connector negative pole of connector, it is characterized in that: described connector anodal with the connector negative pole between be connected by welding a diode, and described diode outer seal sleeve is provided with protective sleeve.
2. a kind of totally-enclosed terminal box according to claim 1 is characterized in that: described connector is anodal can be connected by the buckle connected mode with the connector negative pole.
