Harrisburg是Tyco电子公司的分公司，目前开发了一种小型光伏接线盒。这个接线盒尺寸为：15.5MM*52MM，把直流电传递到太阳能电池板中去，这个小型接线盒巧妙地放到电池板的背面,不影响整体的美观。
这个接线盒最大的特点在于装备了一个弹簧夹金属箔片引线终端，能把接线盒内部的接线轨夹紧以便提高终端系统的整体可靠性。这也减少了劳动密集型的焊接任务。
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.
