The both ends of part are connected with the ground hole on photovoltaic module metal edge frame by bolt realize adjacent photovoltaic component in array respectively
Connection；Array interconnecting piece both ends pass through the ground connection on the ground hole and support on bolt and photovoltaic module metal edge frame respectively
Hole connects, and realizes the connection of photovoltaic module and support；Connector includes the connecting plate and connecting plate positioned at both ends between the array
Between buffer structure, the relevant position on the connecting plate and photovoltaic module support opens up supporting mounting hole, the battle array
The both ends of connector are connected by bolt with the support of adjacent photovoltaic array respectively between row, realize the connection of adjacent photovoltaic array.
Further, it is the input of saving ground connection Hot-dip zinc-coated flat steel sheet material to greatest extent, connector between the array
Horizontal length is 1 ~ 2 meter, only needs to use the battle array with buffer structure in this structure between the photovoltaic array in the distance range
Connector between row, people uses traditional earthing mode, the overall ground connection of the structure between the array of the distance range
Mode can greatly reduce ground connection Hot-dip zinc-coated flat steel sheet material input, save cost, and safety coefficient is higher.
Further, to prevent adjacent array from changing original position relationship because being there is sedimentation by external force and then connect
Part is broken or the problem of loose contact, and the buffer structure of connector is buffering arc structure between the array.
Further, the array interconnecting piece is 4 squares of multiply copper conductors of both ends band connection copper lug.
Further, connector is Hot-dip zinc-coated flat steel sheet material between the array.
Beneficial effect：（1）The present apparatus in view of the shortcomings of the prior art, is on the one hand entered to existing 4 squares of multiply copper conductors
Row is improved, and two is designed as into the structure with connection copper lug, is connected when mounted using bolt with photovoltaic module, the company of raising
The stability connect, generation phenomena such as being grounded deformation, wire lead drop out for avoiding photovoltaic module from occurring in the course of the work, is improved
Construction quality；（2）The present apparatus between adjacent array in the prior art by the way of vertical buried ground connection for can only be caused
Waste of material be improved, for using the special company with buffer structure in the present apparatus between photovoltaic array closely
Fitting, the connector are connected by bolt with photovoltaic module support, and connective stability is higher, and have buffering in the middle part of connector
Structure, prevent adjacent array between because caused by mutual alignment changes connector be broken the problem of, the photovoltaic group of raising
The job stability of part；（3）Scheme provided by the utility model can greatly reduce in work progress buried preparation work and
The preparation of vertical buried material, saves the preparation of a large amount of column and column anchor ears, saves substantial amounts of human input.
