Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inverter assembly and production, and in particular to a product positioning fixture. Background Technology

[0002] A photovoltaic (PV) inverter (or solar inverter) is an inverter that converts the variable DC voltage generated by photovoltaic (PV) solar panels into alternating current (AC) at the mains frequency. This AC voltage can be fed back into commercial power transmission systems or supplied to off-grid power grids. PV inverters are crucial components of PV array systems and can be used in conjunction with general AC-powered equipment. A PV inverter mainly consists of circuit boards such as an I / O board, a BUS CAP board, a communication board, an INV mainboard, an LLC circuit board, a DC board, an RY circuit board, and a BYPASS protection board. The BUS CAP board needs to be mounted on the INV mainboard. Because both the INV mainboard and the BUS CAP board generate significant heat during operation, sufficient space needs to be provided between them for heat dissipation. Therefore, copper pillars for supporting the BUS CAP board need to be pre-installed on the INV mainboard. Due to the small size of the copper pillars and the dense arrangement of components on the INV mainboard, installing the locking holes, copper pillars, and their fastening components on the INV mainboard can be difficult.

[0003] Therefore, this utility model provides a product positioning fixture to solve the problem of copper pillars being difficult to attach to the dense components on the INV motherboard. Utility Model Content

The upper end of the connecting member is disposed on the second plate 2, and the lower end of the connecting member passes through the sliding groove 7. The lower end of the connecting member abuts against the upper surface of the first plate 1. The sliding member 10 has a through hole for the connecting member to pass through, and the connecting member is threadedly connected to the through hole.

[0027] The INV motherboard has a positioning hole through which the first positioning pin 4 passes. When the first positioning pin 4 passes through the positioning hole on the INV motherboard, the circumferential surface of the second positioning pin 5 is externally tangent to the edge of the INV motherboard.

[0028] The nut positioning groove 11 includes a circular groove and a regular hexagonal groove arranged coaxially. The circular groove and the regular hexagonal groove are connected sequentially from top to bottom. The diameter of the circumcircle of the regular hexagonal groove is smaller than the diameter of the circular groove.

[0029] The length of the second positioning pin 5 is greater than the length of the first positioning pin 4. The upper end of the first positioning pin 4 abuts against the lower surface of the third plate, and the upper end of the second positioning pin 5 is disposed through the third plate.

[0030] The connector is a countersunk screw, and the sliding member 10 is a hexagonal nut.
