Abstract
The utility model relates to a sealing device for a photovoltaic module junction box cable lead-out position. A cable is located between a base with a pressing block and a junction box body, the base with the pressing block is connected with the box body through an ultrasonic technology, a silicon rubber case is arranged on the outer surface of the cable, the silicon rubber case is tightly connected with the outer surface of the cable, and the silicon rubber case is arranged among the cable, the pressing block and the junction box body. By adoption of the sealing device for the photovoltaic module junction box cable lead-out position, seal between the cable and the junction box is good, and service life of a product is prolonged.
Description
Technical field
The utility model relates to the solar photovoltaic battery component terminal box, refers to the sealing device of photovoltaic module terminal box cable extraction location especially.
Background technology
In the crystal silicon solar photovoltaic cell component, terminal box plays a part very important.If present solar photovoltaic battery component terminal box adopts ultrasonic technique, terminal box is not carried out the effective seal protection at the position that cable is drawn, and therefore has following problem:
Because process sea transport during the transportation of most assembly, in transportation, collide owing to carrying, aqueous vapor enters terminal box inside along the slit that terminal box contacts with cable easily, causes the burn into electric leakage, can influence overall performance and the safety of assembly in the product use.
The utility model content
The purpose of this utility model is to design the sealing device of photovoltaic module terminal box cable extraction location, makes cable and terminal box good seal.
The utility model for achieving the above object, a kind of sealing device of photovoltaic module terminal box cable extraction location, wherein cable is between the base that has briquetting and terminal box box body, by ultrasonic technique the base that has briquetting is connected with box body, at the cable outer surface silica gel sheath is installed, both closely connect, and silica gel sheath is between cable, briquetting and terminal box box body.
Beneficial effect: good seal prolongs product useful life.
