Description

Bus insulating tape and solar cell module Technical Field The utility model relates to the technical field of solar cells, in particular to a bus insulating tape and a solar cell module. Background In order to smoothly transmit the electric energy in the solar cell module to the external electric equipment, a bus bar is generally arranged in the solar cell module so as to collect the current in the solar cell module, and then the collected current is transmitted to the external electric equipment. Currently, to ensure that the bus bar can be firmly fixed inside the solar cell module, it is generally fixed on the cell film layer of the solar cell module by using a double-sided tape. However, since the shrinkage rate of the adhesive layer of the double-sided tape facing to one side of the bus bar is larger than the shrinkage rate of the bus bar in the high-temperature environment, when the solar cell module is cooled or in the low-temperature environment after being subjected to high-temperature lamination, the double-sided tape can generate acting force for pulling the cell film layer, so that the cell film layer has defects of foaming, degumming and the like, and the generating power of the solar cell module is further affected. Disclosure of utility model In view of the above, the present utility model provides a bus insulating tape and a solar cell module to solve the problems mentioned in the background art. In a first aspect, the present utility model provides a bus bar insulating tape comprising: the insulating tape substrate is provided with a bonding surface and a non-bonding surface which are oppositely arranged, and at least part of the non-bonding surface of the insulating tape substrate is used for being covered on the covered body in a contact manner; The fixing structure is arranged on the non-bonding surface of the insulating tape substrate and is used for being fixed on the bearing surface; And the bus bars are relatively and fixedly arranged on the bonding surface of the insulating tape matrix. The utility model has the beneficial effects that the non-bonding surface of the insulating tape matrix is directly contacted with the covered body (namely the battery film layer in the solar battery assembly), which means that no adhesive exists between the insulating tape matrix and the battery film layer, so that the insulating tape matrix can not generate acting force for pulling the battery film layer in a low-temperature environment, thereby avoiding the problems of foaming, degumming and the like of the battery film layer. Secondly, owing to lack the binder between insulating tape base member and the electric core rete, consequently in order to make insulating tape base member remain in preset position department throughout the follow-up use, through setting up fixed knot structure on the non-bonding face of insulating tape base member, can fix the position of insulating tape base member, avoid it to take place to shift because of vibration or external impact. Furthermore, the bus bar is free from adhesion, so that the adhesion surface of the insulating tape substrate is connected with the bus bar, the bus bar can be effectively prevented from moving randomly, and the relative stability of the position of the bus bar is ensured. In an alternative embodiment, the non-adhesive surface of the insulating tape base body comprises a contact area and a fixing area which are adjacently arranged in the width direction, at least the contact area is a non-adhesive surface and is used for being covered on a covered body in a contact mode, and the fixing structure is arranged in the fixing area. The utility model has the beneficial effects that the non-bonding surface of the insulating tape matrix is divided into the contact area and the fixed area, so that an operator can conveniently determine the installation position of the non-bonding surface of the insulating tape matrix in a short time, and the assembly efficiency is improved. Secondly, the fixing structure is arranged in the fixing area, so that the fixing structure and the covered body are arranged at intervals, and the covered body is prevented from being damaged due to direct contact between the fixing structure and the covered body. In an alternative embodiment, the fixing structures are multiple, and the fixing structures are arranged at intervals along the length direction of the insulating tape base body, or the length of the fixing structures is matched with the length of the insulating tape base body. The utility model has the beneficial effects that the plurality of fixing structures are arranged, so that the connection points between the insulating tape base body and the bearing surface can be increased, the position of the insulating tape base body is more stable, and the displacement of the insulating tape base body caused by vibration or external impact is avoided. Similarly, the length of the fixing structure is matched with the lengt
