Description

A frock for EL test

Technical Field

The utility model relates to a 6 lead wire system battery pack EL test field.

Background

In a standard conventional component, only 4 outgoing lines are provided, the EL test ring section can realize component electrification (1, 2, 3 and 4 outgoing lines are sequentially provided from left to right) only by applying forward voltage to 1 and 4 outgoing lines, but in a component with 6 leading lines, because component strings and strings are relatively independent, not only can direct electrification test be realized, but also short circuit connection is required to be performed on 2 strings, 3 strings, 4 strings and 5 strings so as to achieve the purpose of overall communication, and a design drawing of the whole component with 6 leading lines is shown in figure 3 (a first outgoing line, a second outgoing line, a third outgoing line, a fourth outgoing line, a fifth outgoing line and a sixth outgoing line are respectively provided from left to right).

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: how to enable a standard conventional 4-lead EL tester to measure a 6-lead solar module.

The utility model adopts the technical proposal that: the tool is a non-conductive material plate with a convex structure, two conductive strips which are isolated from each other and have the same size and are in parallel relation are arranged on the front surface of the non-conductive material plate, the width of the head of the tool is smaller than the distance between a second outgoing line and a fifth outgoing line of a 6-lead battery pack, the width of the head of the tool is larger than the distance between a third outgoing line and a fourth outgoing line, the width of the tail of the tool is larger than the width between the first outgoing line and a sixth outgoing line, the tool is installed at the lead of the 6-lead battery pack in the using process of the tool, the third outgoing line and the fourth outgoing line are located on the back surface of the tool, other outgoing lines are located on the front surface of the tool, the first conductive strip is communicated with the first outgoing line and the second outgoing line, and the second conductive strip is communicated with the fifth outgoing line and the sixth outgoing line.

The conducting strips are tinned copper strips.

The utility model has the advantages that: adopt the utility model discloses can make standard conventional 4 lead-out wire EL tester can measure the solar energy component of 6 lead wire systems.

Detailed Description

As shown in fig. 1 and fig. 2, a tooling is manufactured, and the tooling is added before EL test, wherein two tinned copper strips (or other conductors) are arranged in the middle of the front surface; after the components are stacked, 6 outgoing lines are exposed from the through holes of the back plate, as shown in fig. 3, short-circuit connection is needed to be carried out on the second outgoing line and the third outgoing line, the fourth outgoing line and the fifth outgoing line so as to achieve integral communication test, the tool is installed, the second outgoing line and the ground five outgoing line need to be placed on the back face of the tool during placement, the second outgoing line and the ground five outgoing line are used for butt joint of bias voltage, and therefore short-circuit connection of the second outgoing line and the third outgoing line, and the fourth outgoing line and the fifth outgoing line can be completed. The measurement of the 6-lead battery pack is realized. The tool is a non-conductive material plate with a convex structure, two conductive strips which are isolated from each other and have the same size and rectangular structure are arranged on the front surface of the non-conductive material plate in a parallel relation, wherein the thickness of the non-conductive material plate is 1mm-1.5mm, and the thickness of the tin-plated copper strip is 0.35mm-1 mm.
