Description

The photovoltaic connector

Technical field

The utility model relates to the photovoltaic industrial field; Specifically; Relating to a kind of photovoltaic connector, is a vitals of solar module, is between the solar cell array of solar module formation and the connector between the rechargeable solar battery control device.

Background technology

Present solar power station need conflux the small and weak electric energy that all photovoltaic electroplaxs produce and collect; Every electroplax has power supply cable concentrator and the supporting use of connector; But the electric energy that all cable concentrators come out needs the bigger cancellated grid line beam system that has to come the receipt electric energy and send into inverter, and this huge residing environment of network wire harness is very abominable often, not only needs very strong resistance to tension; Reach the waterproof requirement of IP68, and preferably can also carry out on-the-spot installation.Moreover, little for the loss requirement of network wire harness itself, the volume of connection can not be excessive, and these connectors for the network wire harness have all proposed very high requirement.

As a kind of connector of solar module, photovoltaic terminal box significant feature is exactly that the electric energy that solar module produces is derived through cable.Because the particularity of solar cell use occasion and the costliness of itself are worth, the photovoltaic terminal box must have following key property:

(1) shell has strong anti-aging, ultraviolet-resistant capacity;

(2) accord with instructions for use under the outdoor severe environmental conditions;

(3) outstanding radiating mode effectively reduces internal temperature with rational cavity volume, to satisfy the electrical safety requirement;

(4) excellent waterproof, proofing dust and protecting provide safe connectivity scenario for the user.

And the connector that generally adopts at present can not satisfy field erected requirement, and the bigger than normal and bonding strength of volume often is difficult to satisfy.The characteristics of traditional photovoltaic terminal box:

1. design feature:

The housing of open back; Be provided with electrical equipment terminal (slide block) in the housing; The band that respectively confluxes of solar cell template electric energy output end is electrically connected with each input of electrical equipment terminal (distribution hole) accordingly, and cable extend into through the hole of housing one side in the housing and is electrically connected with the output stomidium of electrical equipment terminal opposite side.

advantage:

Adopt the terminal point contact to connect, swift to operate, easy to maintenance.

shortcoming:

Because the existence of binding post, contact resistance is big, and the volume of terminal box is big, thermal diffusivity is relatively poor.

Cable entry port on the housing can cause the water resistance of product to descend simultaneously.Classification of waterproof can only reach IP65 ~ IP67, adopts the some contact to be connected between line and the line, connects reliable inadequately.

Summary of the invention

The purpose of the utility model overcomes the deficiency of prior art, and a kind of advantages of small volume, classification of waterproof height, perfect heat-dissipating, the reliable photovoltaic connector of connection are provided.

The technical scheme that realizes above-mentioned purpose is: a kind of photovoltaic connector; Comprise four photovoltaic cable lines and " ten " font copper pipe internal mold of processing by four copper pipes; The bare exposed conductor that photovoltaic cable line front end peeling back forms is crimped on respectively in the corresponding copper pipe; Be set with heat-shrinkable T bush on the copper pipe, and fastening there is shell on the thermoplastic sleeve pipe, and is marked with silica gel between this shell and the thermoplastic sleeve pipe.

The another kind of technical scheme that realizes above-mentioned purpose is: a kind of photovoltaic connector; Comprise three photovoltaic cable lines and " T " font copper pipe internal mold of processing by three copper pipes; The bare exposed conductor that photovoltaic cable line front end peeling back forms is crimped on respectively in the corresponding copper pipe; Be set with heat-shrinkable T bush on the copper pipe, and fastening there is shell on the thermoplastic sleeve pipe, and is marked with silica gel between this shell and the thermoplastic sleeve pipe.

The advantage of the utility model is following:

1, product is small and exquisite: small product size small and exquisite (cross 80X80X15mm, T font 80X45X15mm), more traditional terminal box volume is little by 60%.

2, low temperature is prone to heat radiation: adopt the solid lathe system terminal of the good metal of thermal diffusivity to replace sheet type electrical equipment terminal, increase contact area with homalographic hydraulic efficiency riveting mode, reduce contact resistance, reduce caloric value.

3, the reliability that connects: adopt the riveting mode, pulling capacity intensity meets the requirement of IPC-620A fully.Easy for installation, be applicable to various installation environments, can reach the water proof and dust proof requirement of IP68.

4, low cost of manufacture is saved material.
