Embodiment Construction
[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar...

The invention discloses a ground photovoltaic copper-aluminum connector with high safety, and relates to the technical field of photovoltaic connection. The ground photovoltaic copper-aluminum connector comprises an installation support, a connecting piece is installed in the middle of the installation support, first water blocking pieces are installed on the left side and the right side of the connecting piece, second water blocking pieces are installed between the first water blocking pieces and the connecting piece, and air storage bins are arranged between the second water blocking pieces and the connecting piece. The second water blocking pieces are connected with sliding covers on the air storage bins through connecting rod hinges, an alarm piece is arranged in each air storage bin, fastening pieces installed on the side walls of the installation support are arranged between the first water blocking pieces and the second water blocking pieces, and the outer side walls of the first water blocking pieces are wrapped by a shell. According to the ground photovoltaic copper-aluminum connector with high safety, the water blocking performance of the copper-aluminum connector is improved, the water inflow early warning function of the copper-aluminum connector is added, and the stability of wire connection is ensured.
Description
technical field [0001] The invention relates to the field of photovoltaic connection technology, in particular to a copper-aluminum connector for ground photovoltaics with high safety. Background technique [0002] In photovoltaic cables, in order to facilitate wiring, it is inevitable to wire the cables, and since most photovoltaic lines are now replaced with aluminum or aluminum alloy conductor cables, the connection between copper and aluminum must be involved in wiring, and the connection between copper and aluminum The connection needs to isolate the external water to avoid the electrochemical corrosion problem between copper and aluminum. Therefore, the sealing of the connector can be very important, while the traditional copper-aluminum connector only passes through a certain diameter during use. The size of the sealing ring is sealed. The traditional sealing ring only completes the sealing through its own tension. After a long time of plastic setting, the tension dec...
