Abstract

The utility model discloses a line-pressing device of a solar junction box, which comprises a line-pressing plate and a triangular spring plate, wherein the line-pressing plate comprises a pair of line-pressing legs and a limiting piece, the triangular spring plate is buckled on the limiting piece in a circling manner, and the pair of line-pressing legs are abutted against the two sides of the limiting piece and are pressed at one corner piece of the triangular spring plate in a bent manner. Through the above mentioned mode, the line-pressing device of the solar junction box is prevented from being impacted by an external conductor during the connection process, that the stainless steel spring plate never deforms during the connection can be ensured, and the stability in line pressing is improved.

Description

The cord grip of solar junction box

Technical field

The utility model relates to technical field of solar, particularly relates to a kind of inner cord grip of solar junction box that is used for.

Background technology

Solar junction box is the important component part of solar-electricity source component; Be widely used in the various sun-generated electric power devices; Because the binding post in the terminal box is the cell module panel of connecting circuit components and parts and the critical component of other element; Therefore the requirement of pair of wire connection terminals has safe and reliable connectivity, and stronger chucking power and contact pressure are arranged, and better corrosion resistance and conductivity will be arranged.

Continuous development along with heliotechnics; The specification requirement of the terminal box specification that component palette is used is also improving constantly; The particularly birth of amorphous silicon membrane cell module panel requires the specification of terminal box to develop to little and thin direction, and this just makes the terminal box volume inside more and more littler; Original design adopts contact chip and diode or welding to be welded; But the time occur rosin joint easily or overlong time causes the too high meeting of temperature that diode is burnt out in welding, particularly changing or easy burn-out during the maintenance maintenance diode, this is for operation is very inconvenient out of doors; Thereby a kind of in addition is to adopt clamping kit that a kind of stainless steel shell fragment terminal is compressed on by means of fixture to make no longer off-line of Connection Element on the terminal block; But the stainless steel shell fragment can produce little distortion in the course of time; The line effect shows a lot of shortcomings all the more; Cause between the element problems such as loose contact, therefore need a kind of not only handled easily especially but also be beneficial to the cord grip of lasting connection.

The utility model content

The technical problem that the utility model mainly solves provides a kind of cord grip of solar junction box, can not influenced by external conductor, makes behind the stainless steel shell fragment line ball forever indeformablely, improves line ball stability.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the cord grip that a kind of solar junction box is provided; Comprise: tension disc and triangle shell fragment; Said tension disc comprises a pair of line ball pin and banking stop, and said triangle shell fragment latch closure is in banking stop, and said a pair of line ball pin rolls over and be pressed on a corner of triangle shell fragment near the banking stop both sides.

In preferred embodiment of the utility model, said triangle shell fragment is three, and the triangle shell fragment comprises first, tail surface and median surface around forming, and wherein tail surface offers a rectangle spacing hole.

In preferred embodiment of the utility model, said a pair of line ball pin and banking stop are structure as a whole, and line ball pin height is less than the height of banking stop.

In preferred embodiment of the utility model, the first of said triangle shell fragment is close to banking stop.

The beneficial effect of the utility model is: the cord grip of the utility model solar junction box makes tension disc and triangle shell fragment by means of the interaction force between the inner body in the wiring process; Produce self-locking state; Reduced stressed to external conductor; Also improved the useful life of triangle shell fragment, made line ball reliable and stable.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection range of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

See also Fig. 1, Fig. 2 and Fig. 3; The utility model embodiment comprises: a kind of cord grip of solar junction box; Comprise: tension disc 1 and triangle shell fragment 2, offer a pair of line ball pin 11 and banking stop 12 on the tension disc 1, triangle shell fragment 2 latch closures are in banking stop 12; A pair of line ball pin 11 is near banking stop 12 both sides, and folding is pressed on a corner of triangle shell fragment 2.A pair of line ball pin 11 and banking stop 12 are structure as a whole and adopt copper coin to carry out the manufacturing of pressing and bending technology to form, and the height at line ball angle 11 is less than the height of banking stop 12.

See also Fig. 2; Said triangle shell fragment 2 be three around forming; Comprise first 22, tail surface 23 and median surface 24, wherein tail surface 23 offers a rectangle spacing hole 21, and the tail surface 23 that has rectangle spacing hole 21 is socketed on the top of banking stop 12; The end width of banking stop 12 is slightly less than the width of rectangle spacing hole 21, so that spacing hole 21 can pack into the top of banking stop 12.Triangle shell fragment 2 firsts 22 are close to banking stop 12, and the triangle shell fragment 2 that annular interlocks is in fixed condition, can not produce any distortion or loosening.

See also Fig. 4; The cord grip of the utility model solar junction box adopts a triangle shell fragment 2 to accomplish being electrically connected of tension disc 1 and welding 3; On the tail surface 23 of triangle shell fragment 2, have a rectangle spacing hole 21, the end protrusion at tension disc 1 is provided with a banking stop 12 simultaneously.Wherein the first 22 with triangle shell fragment 2 is close on the convex closure wall 13 of banking stop 12; Be clipped in welding 3 between banking stop 12 and the triangle shell fragment 2; Realize that welding 3 contacts with face between the tension disc 1; The tail surface 23 that then triangle shell fragment 2 is had a spacing hole 21 is socketed in the top of banking stop 12 protrusions; Using specific purpose tools with its inside bending, be pressed on the first 22 of triangle shell fragment 2 and the bending part of median surface 24 at last, make the more fastening subsides jail of triangle shell fragment 2 on the banking stop 12 of tension disc near a pair of line ball pin of banking stop 12 both sides 11.Because the elastic force direction that triangle shell fragment 2 is had is that it possesses the tendency of stretching; Median surface 24 makes first 22 and tail surface 23 that the trend of stretching out arranged all the time; Therefore can be owing to the lax of elastic force fluffs the conflict between banking stop 12 and the rectangle spacing hole 21, the reliability of connection, stability are all very high.

The cord grip of the utility model solar junction box is different from prior art: utilize the elasticity of triangle shell fragment self, be socketed on the tension disc, and not by means of other external force, triangle shell fragment and tension disc self-locking are fitted, connect and stablize, long service life.

The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
