Summary of the invention
The utility model object is to provide a kind of photovoltaic DC-to-AC converter cable connection structure, by the improvement of syndeton, ensureing, on the basis of switching performance, to improve working (machining) efficiency, is suitable for mass production.
For achieving the above object, the technical solution adopted in the utility model is: a kind of photovoltaic DC-to-AC converter cable connection structure, comprise bus and branch line, in described bus, include some heart yearns, each root heart yearn is electrically connected with described branch line through pin configuration, described pin configuration comprises the tuning fork terminal being electrically connected with described heart yearn, described tuning fork terminal front end is mainly by both sides cutter arm and be arranged at the contact pin in groove between described cutter arm and form, distance described in both sides between cutter arm is less than the diameter of described heart yearn, described contact pin front end inserts in described heart yearn, with metal-cored electrical connection in this heart yearn, the rear end of described tuning fork terminal is connected with described branch line.
In technique scheme, cutter arm is positioned at middle part and is provided with turning described in both sides, forms to narrow horn mouth gradually in groove, and described turning end is narrow end, and outer openings end is wide end.
In technique scheme, described contact pin is a taper, and its front end extends to the middle part of cutter arm described in both sides to described tuning fork terminal openings side.
In technique scheme, the middle part of described tuning fork terminal is provided with bending section, is Z-shaped, and the rear end of described tuning fork terminal arranges that through being parallel to described heart yearn bending section is connected with front end.
Further technical scheme is, the front end of the described tuning fork terminal on adjacent described heart yearn is cross-linked layout, the rear end of described tuning fork terminal in same level or mutual spacing be less than 1 ㎜.In same plane or approach in conplane space, can dwindle as far as possible the size that coordinates pilot hole in male end, save space, be also convenient to the grafting of assembling and male end simultaneously.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the utility model adopts tuning fork terminal front end directly and heart yearn grafting, cut heart yearn surface insulation layer in bus by both sides cutter arm and middle contact pin, contact with metal-cored, the rear end of tuning fork terminal is connected with separated time, thereby complete good electrical connection, simultaneously in technique, without peeling operation, the grafting of directly exerting pressure, simple process, time saving and energy saving, improve working (machining) efficiency, be beneficial to mass production;
2. in the cutter arm of both sides, turning is set, narrow outer wide horn mouth in forming, coordinates tape pin, is convenient to cutter arm on the one hand and cuts the insulator on heart yearn surface, easy to assembly; Increase on the other hand metal-cored contact area in tuning fork terminal and heart yearn, improve the stability connecting;
3. tuning fork terminal middle part is provided with bending section, be Z-shaped, thereby can realize in the time of the sub-interlaced arrangement of adjacent tone fork, the rear end of tuning fork terminal and come same plane or small distance space in, save space, be convenient to the installation of male end and the grafting of male end.
