摘要

#CMT# #/CMT# The junction box (4) has support portion which is provided for fastening terminal and junction box on solar module (2). A peripheral side wall (8) is provided with cable opening (20). A connector is provided in cable opening for connecting the cable (6) to terminal and junction box. The force which is greater than predefined threshold value is applied with respect to cable. An indicator device (10) is provided for displaying amount of application of force on cable. The indicator device is made of thermoplastic material. The axial length of the case is set to 5-30 mm. #CMT#USE : #/CMT# Terminal and junction box for photovoltaic solar module (claimed). #CMT#ADVANTAGE : #/CMT# The proper handling of the solar module can be ensured. The damage of terminal and junction box can be prevented. The stress applied to the cable can be prevented. The rupture, elongation, discoloration or deformation of the cable can be prevented. The brittleness of indicator device can be improved. The indicator device can be manufactured easily. The reliability of the terminal and junction box can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic view of the terminal and junction box and perspective view of the indicator device. 2 : Solar module 4 : Terminal and junction box 6 : Cable 8 : Peripheral side wall 10 : Indicator device 20 : Cable opening.
