Description

Fixed clamp for connecting PV modules

Technical field

The invention relates to the technical field of fixing a wire clamp, in particular to a fixed wire clamp for connecting a wire of a photovoltaic component.

Background technique

At present, there is no proprietary fixed clamp for the connecting wires between the photovoltaic modules. In practical applications, the universal cable tie is usually used to tie the connecting wires, and then inserted into the C-shaped steel trough of the photovoltaic module bracket or freely suspended in the photovoltaic module. back.

The universal cable ties generally have plastic cable ties and iron core ties, which are widely used in electronic factories, tying televisions, computers and other internal connecting lines, fixing of wires, motors, electronic toys, etc., with fast binding and insulation. Features such as good sex, self-locking, and easy to use.

The existing cable tie is applied to the bundling of the connecting wires of the photovoltaic components, and has the following defects:

Defect 1: The PV module is a solar power installation installed outdoors. The connecting wires are exposed to the external open environment throughout the life cycle. The solar radiation, wind and rain, and temperature difference vary greatly. The universal cable tie is used indoors. The long-term durability of the products cannot meet the site requirements, and needs to be replaced frequently to increase on-site labor and installation procedures. The cable tie that is replaced at the same time is often discarded at random to pollute the environment.

Defect 2: The main function of the cable tie is to tie a plurality of wires together or tie the wires together with other solid objects to achieve the fixing effect of the wires. The photovoltaic module is a standardized product, and the whole device has no position for tying the cable. In reality, the wire is bundled and then inserted into the C-shaped steel groove of the photovoltaic module bracket, or freely suspended on the back of the photovoltaic module, and the wire is not fixed. In terms of the wind, the wire is worn and the tensile force of the photovoltaic module junction box is broken. On the other hand, messy wires affect the overall landscape quality of photovoltaic power plants.

Defect 3: The cable tie is a very small material, which is often left in the field in actual conditions, causing environmental pollution. In addition, in the harsh open air environment, the small cable tie falls off after aging in a short period of time. It also causes environmental pollution.

Therefore, those skilled in the art are working to develop a photovoltaic module connecting wire for facilitating the fixing of the connecting wires of the photovoltaic module, facilitating the installation and facilitating the regular arrangement of the connecting wires, and reducing the hidden trouble points caused by the swinging of the connecting wires in the photovoltaic power station. Fixed clamps.

Summary of the invention

In view of the above-mentioned deficiencies of the prior art, the present invention provides a photovoltaic module connection for facilitating the fixing of the connecting wires of the photovoltaic module, facilitating the installation and facilitating the regular arrangement of the connecting wires, and reducing the hidden trouble points caused by the swinging of the connecting wires in the photovoltaic power station.

In order to achieve the above object, the present invention provides a fixing clip for a photovoltaic module connecting wire, comprising a fixing clip seat clamped on a frame or a bracket of the photovoltaic module, and a fixing wire ring for fixing the connecting wire; the fixing clip seat The U-shaped clamp base is disposed on an outer side surface of the fixed clamp base.

As a further improvement, the fixing clip and the fixing wire ring are integrally formed.

As a further improvement, the fixed clip and the fixed wire loop are provided in a split configuration.

As a further improvement, the fixing wire loop is snap-fitted to the outer side surface of the fixing clip.

As a further improvement, the fixed wire loop is rotatably disposed on an outer side surface of the fixed clamp.

As a further improvement, the fixed wire loop is a closed ring.

As a further improvement, a gap is formed in the closed ring for the connecting wire to be inserted.

As a further improvement, the number of the fixing wire loops is two or more, which are respectively disposed on different outer side faces of the fixing clip seat.

As a further improvement, the fixing clip is used for clamping the inner side surface of the photovoltaic module to be arranged as a sawtooth array surface or a dot array surface.

As a further improvement, the fixing clip is for holding an adhesive layer on the inner side surface of the clamping photovoltaic module.

The beneficial effects of the fixed wire clamp for connecting the wires of the photovoltaic module of the present invention are as follows:

1. The invention can be clamped on the frame or the bracket of the photovoltaic module by the fixing clip, and the connecting wire is connected by the fixing wire loop to fix the connecting wire on the frame or the bracket of the photovoltaic module. The whole process does not affect the photovoltaic components, and the connecting wires are arranged at the same time, which avoids the wear of the connecting wires under the action of the wind, and eliminates the tensile damage caused by the connecting boxes when the connecting wires are suspended on the back of the photovoltaic module, thereby eliminating the hidden trouble points.

2. The use of the fixed clamp of the present invention instead of the cable tie effectively eliminates the hidden worries of the existing cable tie in the photovoltaic power plant, and avoids the impact of the cable tie falling on the site, aging off, and random disposal.
