Abstract
The utility model discloses a terminal used for a photovoltaic junction box. The terminal comprises a cooling fin and a clamping terminal. One end of the cooling fin is provided with a clamping groove. A tail portion of the clamping terminal is in an arc shape. The other end of the clamping terminal is provided with a buckling hook. An open circular ring is arranged on an intermediate portion of the clamping terminal. The circular ring possesses elasticity. The tail portion of the clamping terminal is fixedly connected with the circular ring through a first connection arm. The buckling hook is fixedly connected with the circular ring through a second connection arm. The structure of the terminal is simple, manufacturing cost is low and operation is simple. An extra tool does not need to be used. The terminal and an afflux belt form surface contact so that a contact resistance is reduced, power consumption of a contact position is decreased, a calorific value is reduced and the service life of the junction box is prolonged.
Description
Technical field
The utility model relates to basic electrical component technical field, especially connecting terminal for photovoltaic junction box.
Background technology
Photovoltaic junction box is the important component part of solar photovoltaic assembly, be widely used in various sun-generated electric power devices, because the binding post in terminal box is the critical component of the cell module panel busbar of connecting circuit components and parts, therefore just require binding post to there is safe and reliable connectivity, there is the stronger power of holding and contact, the less contact resistance of adding.
Existing junction box for photovoltaic module has two kinds of modes that assembly exit is connected with terminal box back panel wiring terminal, one is welding manner, be welded on binding post by scolding tin etc. by convergent belt, this mode troublesome poeration, need to be by instruments such as electric iron, and use for a long time scolding tin to have certain infringement to operative employee's health; In addition, due to the problem such as exit busbar is thicker or welding temperature is not up to standard, easily cause the problem of the not prison welding such as rosin joint, sealing-off, in later stage use procedure, cause hidden danger of quality.Another kind is snap fit, directly convergent belt is stuck on binding post by clamp, and this mode is easy and simple to handle.But be mainly two kinds of employing point contact or line contacts in the market, the contact portion between convergent belt and binding post is by a point or a line.Line contact has following two kinds, vertical direction snap fit: convergent belt is from terminal box terminal upper portion inserted terminals inside, and now convergent belt is substantially vertical with assembly plane, and contact portion shape is into a line; Horizontal direction snap fit: convergent belt inserts from terminal bottom one side, and now convergent belt is substantially parallel with assembly plane, and contact portion shape is into a line.The shortcoming of above-mentioned two kinds of ways of contact is exactly easily to cause the contact resistance between convergent belt and binding post excessive because contact area is too small, like this assembly in use, likely because the contact resistance of this part large, generate heat high and burn the even whole assembly of terminal box.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of connecting terminal for photovoltaic junction box, simple in structure, and cost of manufacture is low, easy and simple to handle, without using additional means; Binding post is face with convergent belt and contacts, and has reduced contact resistance, has reduced the power consumption of contact site, has reduced caloric value, has extended the useful life of terminal box.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of connecting terminal for photovoltaic junction box, comprise fin and clamping terminal, and one end of fin is provided with buckling groove; Clamping terminal tails is circular-arc, the clamping terminal other end is provided with fastening hook, is provided with the annulus of opening in the middle of clamping terminal, and described annulus has elasticity, clamping terminal tails is fixedly connected with described annulus by the first linking arm, fastens hook and is fixedly connected with described annulus by the second linking arm.
Side, position near clamping terminal tails on fin is provided with convergent belt socket.
The material of fin is that copper nickel plating or copper are zinc-plated.
The material of clamping terminal tails, the first linking arm, the second linking arm and fastening hook is that copper nickel plating or copper are zinc-plated.
Fin is provided with installing hole.
The beneficial effect that adopts technique scheme to produce is: the utility model connecting terminal for photovoltaic junction box is simple in structure, and cost of manufacture is low, easy and simple to handle, without using additional means; Metal part is semicircle arcuation, makes binding post and convergent belt be face and contacts, and has reduced contact resistance, reduces the power consumption of contact site, has reduced caloric value, has extended the useful life of terminal box.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model injects the structural representation after convergent belt fastens;
1 is fin, and 2 is buckling groove, and 3 for clamping terminal tails, and 4 for fastening hook, 5 annulus that are opening, and 6 is the first linking arm, and 7 is the second linking arm, and 8 is convergent belt.
Embodiment
A kind of connecting terminal for photovoltaic junction box, comprises fin 1 and clamping terminal, and one end of fin 1 is provided with buckling groove 2; Clamping terminal tails 3 is circular-arc, the clamping terminal other end is provided with and fastens hook 4, in the middle of clamping terminal, be provided with the annulus 5 of opening, described annulus 5 has elasticity, clamping terminal tails 3 is fixedly connected with described annulus 5 by the first linking arm 6, fastens hook 4 and is fixedly connected with described annulus 5 by the second linking arm 7;
The annulus of opening is major axis shape, and axle is fixed on fin;
Side, position near clamping terminal tails 3 on fin 1 is provided with convergent belt socket;
The material of described fin 1 is that copper nickel plating or copper are zinc-plated;
The material of clamping terminal tails 3, the first linking arm 6, the second linking arm 7 and fastening hook 4 is that copper nickel plating or copper are zinc-plated;
The utility model is installed on standby position by the installing hole on fin while use, convergent belt is injected in fin along convergent belt socket or along the hole between binding post and mounting platform, hook is closed in clinching downwards, fastening hook and buckling groove fastens, because clamping terminal tails is semicircle arcuation, therefore clamping terminal tails and convergent belt contact portion form the face of a semicircle arcuation, contact area is large, clamping is firm, reduce contact resistance, reduce power consumption, reduced caloric value, increased terminal box useful life.
