Harrisburg是Tyco電子公司的分公司，目前開發(fā)了一種小型光伏接線盒。這個接線盒尺寸為：15.5MM*52MM，把直流電傳遞到太陽能電池板中去，這個小型接線盒巧妙地放到電池板的背面,不影響整體的美觀。

這個接線盒最大的特點在于裝備了一個彈簧夾金屬箔片引線終端，能把接線盒內(nèi)部的接線軌夾緊以便提高終端系統(tǒng)的整體可靠性。這也減少了勞動密集型的焊接任務(wù)。

Harrisburg, Pa.-based Tyco Electronics (TE) has developed the SOLARLOK slim junction box. This junction box, measuring 15.5 mm by 52 mm, distributes DC power to a solar panel in a compact design with low visibility on the back of a panel, the company says.

The TUV Rheinland-approved product meets stringent industry requirements and offers a 20-year product-life performance. Targeted applications include two-rail crystalline PV modules and two-rail thin-film PV modules, with a 12 A current rating for crystalline applications and a 3 A current rating for thin-film applications.

The junction box reduces purchasing costs by offering a total assembly that includes solar-rated cables, which are available in various lengths to suit a wide variety of applications, TE adds. The assembly also includes IP67-rated SOLARLOK connectors, which produce an audible click to ensure proper installation and include a locking latch feature that meets code requirements.

A key feature of the junction box assembly includes a spring clamp for termination of the foil leads, which clamps to the contact rail inside the box for increased overall reliability and ease of termination. This feature also eliminates the labor-intensive task of soldering, TE notes.
