Abstract
The utility model relates to a connecting terminal of a junction box for a solar energy power supply device. The connecting terminal comprises a contact piece, a bracket and a spring. The contact piece is arranged inside the bracket, is provided with a cable socket at one end thereof and is provided with a conducting strip and a hook at the other end thereof, the bottom surface of the conducting strip is connected with the bottom surface of the bracket through the spring, a pressing hole is formed on the top surface of the bracket in the corresponding position of the conducting strip, and a circular arc-shaped end surface is formed on the top surface of the bracket. In the connecting terminal provided by the utility model, the spring with double ends folded is more stable, so that the clamping force of the contact piece is relatively uniform; the contact piece, made of red copper subjected to silver plating treatment, has good electrical conductivity; and the hook can avoid displacement of the spring during operation. The connecting terminal, with stainless steel and silver plated red copper as raw materials, has the advantages of good corrosion resistance, simple structure, good safety and reliability, good clamping force, small contact resistance and good electrical conductivity, and can be used as a component of a product or a single universal product.
Description
Technical field
The utility model belongs to the sun-generated electric power field of components, particularly relates to a kind of sun-generated electric power device terminal box parts.
Background technology
The photovoltaic terminal box is the vitals of solar-electricity source component, be widely used in the various sun-generated electric power devices, because the binding post in the terminal box is the critical component of the cell module panel busbar of connecting circuit components and parts, therefore just require binding post to have safe and reliable connectivity, stronger chucking power and contact pressure are arranged, less contact resistance, good corrosion resistance and conductivity.
Continuous development along with solar-photovoltaic technology, the specification requirement of the terminal box specification that component palette is used also improves constantly, particularly along with the birth of amorphous silicon membrane cell module panel, require the specification of terminal box to develop to little and thin direction, this just makes the inner space of terminal box more and more littler.Original design adopts contact chip and diode or busbar to be welded, but because welding the time occurs rosin joint easily or overlong time causes the too high meeting of humidity that diode is burnt out, very easily burn out during particularly in replacing or at the maintenance maintenance diode, this is very inconvenience for operation in the open air, so the utmost point needs a kind of not only handled easily but also is beneficial to the binding post of connection performance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sun-generated electric power device terminal box binding post, to solve the unhandy defective of installation, maintenance in the prior art.
A kind of sun-generated electric power device terminal box binding post, form by contact chip, support, three parts of spring leaf, described contact chip is contained in the support, the one head is the cable socket, the other end is conducting strip and has gib head, the underrun spring leaf of conducting strip links to each other with the support bottom surface, and described cradle top surface has on the corresponding position of conducting strip and pushes the hole, and cradle top surface also has the end face of a circular arc.
Described spring leaf is the folding triangle spring sheet of double end.
Described contact chip is made by red copper is silver-plated.
Described support and spring leaf adopt stainless steel to make.
Beneficial effect
The utility model spring leaf then adopts double end folding, spring is more steady, thereby make the chucking power of contact chip more even, contact chip then adopts the red copper through silver-plated processing, conducts electricity very well, gib head prevents that spring leaf is shifted at work, adopt stainless steel and silver-plated red copper as raw material, the product corrosion resistance is strong, simple in structure, safe and reliable, have good chucking power, contact resistance little, conduct electricity very well, both can be used as the parts of product, also can be used as the single universal product.
