Between be connected with diode；The connection end of cable and a binding post riveting of terminal box；The bottom surface of described box body is set
There are glue groove and multiple raised contour locating dowels, paste terminal box and photovoltaic module after silica gel has been noted in glue groove
When, described locating dowel is abutted with component.
It is preferred that, the angle between the outlet direction and box body of described cable is 45 °.
Further preferably, described nylon bottom plate is provided with multiple hot melt anchor points, and described binding post passes through described
Anchor point is heated to position and fix by heating with nylon bottom plate.
Further preferably, the caulking part of the binding post connection of the connection end of the cable and terminal box is provided with two rivetings
Point.
Further preferably, it is also covered with the caulking part that the binding post of the connection end of the cable and terminal box is connected
Scolding tin.
Further preferably, described halfway junction box is provided with Handheld Division.
Further preferably, described cable is provided with cable connection end fixed block, described fixation with terminal box junction
Block is fixed by ultrasonic heat blow with box body.
The improved combined type photovoltaic component terminal box of the present invention, cable is occurred using oblique angle, is easy to cabling and is reduced
The bending of line, extends its service life；Using independent nylon bottom plate, make terminal box that there is excellent high current conducting and resistance to height
Warm ability；Cable uses double rivetings with binding post and applies scolding tin, improves the reliability of connection；The terminal box back side sets convex
Play structure, it is ensured that the terminal box reliability Nian Jie with component.
