Technical field
The utility model is related to photovoltaic module technical field, more particularly to a kind of terminal box is filled with busbar pull force calculation
Put.
Background technology
In solar photovoltaic industry, terminal box is the current output terminal mouthful of photovoltaic module, by busbar and terminal box
The binding post connection in portion.The connection of busbar and connection terminal generally has following three kinds of methods：Jump ring, jump ring, which are welded with, to be connect, welds
Connect；Current non-potting compound junction box is mainly connected by jump ring, and potting compound junction box is mainly welded with the connection connect by welding and jump ring
All there is busbar and unstable phenomenon be connected with binding post in mode, three kinds of connected modes, so as to cause contact resistance to become big
Burning terminal box causes component failures.
In the prior art, the value of thrust of detection terminal box and busbar mainly uses common tensiometer, tensiometer shape
It is bigger than normal, troublesome poeration；Being designed as of its hook can cause busbar to deform in fishing hook form, test process, and the shape of fish hook
All terminal boxes can not be adapted to；The fineness of hook can not also meet the requirement of terminal box.
In view of drawbacks described above present in prior art, is badly in need of a kind of for detecting terminal box and busbar pulling force at present
Equipment, to meet the demand of different terminal boxes, and the device structure is simple, it is easy to promote.
The content of the invention
In order to overcome drawbacks described above present in prior art, the utility model provides a kind of terminal box and drawn with busbar
Force checking device, the stretching force detecting apparatus includes pull bar, piston, lever, hook and spring, it is characterised in that：
One end of the pull bar is provided with the lever, and the other end is provided with the hook；
The spring and piston are arranged on the inside of the lever, and the spring is connected with piston machine；
The pull bar is connected with the piston machine.
According to one side of the present utility model, the material of the hook is that wolfram steel or one or more are high-strength
Spend the combination of material.
According to other side of the present utility model, the hook is shaped as cylinder, and the cylindrical diameter
Scope is 1mm~3mm.
According to another aspect of the present utility model, the angular range of the hook and the pull bar is 75~100 degree.
According to another aspect of the present utility model, graduation mark is provided with the surface of the lever.
A kind of terminal box that the utility model is provided and busbar stretching force detecting apparatus, can accurately detect terminal box
Whether the value of thrust between busbar is within the scope of qualified.The hook of stretching force detecting apparatus uses the material of wolfram steel simultaneously
Matter, hook is shaped as cylinder, can meet the demand of different terminal boxes, improve the speed of pull force calculation, reduces inspection
The survey time.Stretching force detecting apparatus is simple in construction, and cost is low, it is easy to production and popularization.
Brief description of the drawings
It is of the present utility model by reading the detailed description made to non-limiting example made with reference to the following drawings
Other features, objects and advantages will become more apparent upon：
Fig. 1 is that a kind of terminal box provided according to the utility model is embodied with a kind of of busbar stretching force detecting apparatus
The structural representation of mode；
Same or analogous reference represents same or analogous part in accompanying drawing.
Embodiment
In order to more fully understand and explain the utility model, make further detailed to the utility model below in conjunction with accompanying drawing
Thin description.
The utility model provides a kind of terminal box and busbar stretching force detecting apparatus, refer to Fig. 1, and Fig. 1 is according to this
The structural representation of a kind of terminal box that utility model is provided and a kind of embodiment of busbar stretching force detecting apparatus, institute
Stating stretching force detecting apparatus includes pull bar 1, piston 2, lever 3, hook 4 and spring 5, it is characterised in that：
One end of the pull bar 1 is provided with the lever 3, and the other end is provided with the hook 4；
The spring 5 and piston 2 are arranged on inside the lever 3, and the spring 5 is mechanically connected with the piston 2；
The pull bar 1 is mechanically connected with the piston 2.
In one specific embodiment, the material of the hook 4 is wolfram steel；Preferably, the material of the hook 4 can be with
For the combination of one or more of high-strength materials.Hook 4 is shaped as cylinder, in the present embodiment, the diameter of the hook 4
Scope is 1mm~3mm, and the angular range of the hook 4 and the pull bar 1 is 75~100 degree.
In the present embodiment, it is provided with graduation mark on the surface of the lever 3.
In a kind of specific embodiment, when there is terminal box to need to carry out pull force calculation, drawn first with the hook 4 of cylinder
The firmly busbar of terminal box to be measured, test man is arranged on the piston 2 inside lever 3 by the lifting busbar upwards of lever 3, band logical
Worked with spring 5, while observation is arranged on the graduation mark on lever 3.When graduation mark reaches standard tension value, if busbar is not
Depart from the binding post of junction box, then terminal box welding quality is qualified；If busbar departs from the terminals of junction box
Son, then terminal box welding quality is unqualified, it is necessary to weld again.
