Abstract

The invention discloses a quick junction box. The quick junction box comprises a box body, wherein a metal electric conduction sheet and a clamping spring are arranged in the box body; the section of the clamping spring is in a C shape with an upward opening; two sides of the opening are respectively provided with an upward turned-over edge; one end of the metal electric conduction sheet is bent to form a holding hole corresponding to the clamping spring, and the clamping spring is located in the holding hole; and bottom two sides of the holding hole of the metal electric conduction sheet are respectively provided with an openable moving buckle. The quick junction box has the advantages that the manufacture is convenient, the operation of inserting omnibus bar is simple and the junction effect is good.

Description

Quick connector

Technical field

The present invention relates to a kind of quick connector, comprise box body, in box body, be provided with metallic conduction sheet and jump ring.

Background technology

Along with the application of solar power generation is more and more general, also constantly weed out the old and bring forth the new with the closely-related terminal box of its application, many groups solar module that solar power generation adopts matrix form to arrange, transform light energy is become to electric energy, each group solar module is connected with terminal box, terminal box is connected with other parts of solar power system again, due to terminal box long-term work out of doors, the reasonability of Design of Mechanical Structure and the quality of quality are directly connected to the efficiency of electrical transmission.

Solar module is to be connected with terminal box by busbar, and both connectivity robustness directly have influence on the quality of terminal box.Chinese invention patent publication number is 101272039 to disclose a kind of terminal box, its conducting strip rear portion has the indent position of a U-shaped, one flexure strip inserts this indent position, this flexure strip comprises a perpendicular edge and a free end with a rectangular opening, the front end cutting ferrule of rectangular opening is fixed in the outer perpendicular edge at conducting strip indent position, the perpendicular edge of flexure strip is posted by the medial surface at conducting strip indent position, by wedge tool, the medial surface of the perpendicular edge of flexure strip and conducting strip is opened, thereby fill in busbar, unclamp wedge tool, busbar can be sandwiched between the two, conducting strip rear portion is to be embedded in junction block, in order to improve wiring fastness, between conducting strip rear portion and junction block, insert elasticity swelling sheet.The shortcoming of this structure is: number of parts is many, and the machining accuracy of any one part is careless mistake slightly, will affect wiring effect; In addition the perpendicular edge of flexure strip abuts on the medial surface of outer perpendicular edge at conducting strip indent position, and the free end of flexure strip is fixed with this outer perpendicular edge, therefore more difficult when use wedge tool is separated the perpendicular edge of flexure strip and conducting strip.

Summary of the invention

The object of this invention is to provide the simple terminal box of a kind of technique, engage easily with busbar, and engage effective.

For this reason, the technical solution used in the present invention is such: quick connector, comprise box body, and in box body, be provided with metallic conduction sheet and jump ring, jump ring cross section is " C " shape and opening upwards, and opening both sides respectively have a flange making progress; Metallic conduction sheet one end is bent to form an accommodation aperture corresponding with jump ring, and jump ring is placed in one; Metallic conduction sheet accommodation aperture two bottom sides limit respectively have one can folding movable button.

For further improvement, outside the flange of jump ring opening both sides, respectively there is a through hole.

As further improving, there is the end of stopping the accommodation aperture top of metallic conduction sheet, stops and holds the projection of in the vertical direction within the scope of jump ring.

During installation, make the opening of jump ring corresponding with the opening of metallic conduction sheet accommodation aperture, from metallic conduction sheet side, push away jump ring and enter accommodation aperture, on the activity button-fold of accommodation aperture two bottom sides, fasten jump ring, fixedly secure jump ring and metallic conduction sheet, prevent from becoming flexible between the two, at jump ring, be pushed into after accommodation aperture, the both sides of jump ring are near the front and back inwall of accommodation aperture.The end that stops that metallic conduction sheet of the present invention arranges in its accommodation aperture upper end is preferably four tooth shape ends, and approach the upper surface of jump ring, these four tooth shape ends do not cover the through hole of jump ring upper surface, and the side in jump ring upper surface flange, because the distance between tooth shape end and the upper surface of jump ring is very little, jump ring can not be taken out from top, therefore can prevent that jump ring from coming off from accommodation aperture top.

During use, with pliers, clamp through hole or the flange of jump ring upper end open both sides, can be so that jump ring distortion, originally the madial wall of jump ring and metallic conduction sheet accommodation aperture is close together, at this moment produce space between the two, busbar is filled in this space, then pliers is unclamped, after jump ring restores to the original state, busbar is just tightly stuck between jump ring and metallic conduction sheet.

The present invention is easy to make, and inserts the simple to operate of busbar, and wiring is effective.

Embodiment

Embodiment 1

Referring to Fig. 2, jump ring 5 is " C " shape and opening upwards, and upper surface open both sides correspondence is respectively with a flange 4.Referring to Fig. 3, metallic conduction sheet 1 front end has accommodation aperture 2, and size is mated with jump ring 5; The two bottom sides limit of accommodation aperture 2 each with one can folding movable button 3, the folding direction of movable button 3 is parallel with accommodation aperture 2 lateral opening directions; The madial wall of accommodation aperture 2 possesses friction rib 6.

Referring to Fig. 1 and Fig. 4, metallic conduction sheet 1 is contained in box body 8 with jump ring 5, during assembling, first opens movable button 3, and jump ring 5 enters accommodation aperture 2 from a thruster, and the movable button 3 that then closes is fixed in accommodation aperture 2 jump ring 5.During use, only need instrument, as pliers, clamps two flange 4 on jump ring 5, and between the sidewall of jump ring 5 and accommodation aperture 2, insertion busbar in meeting generation ，Yu gap, gap, then unclamps jump ring 5, and jump ring 5 can clamp busbar with together with the madial wall of accommodation aperture 2.

Embodiment 2

Referring to Fig. 5, as different from Example 1, outside the flange 4 of jump ring 5 upper end open both sides, respectively there is a through hole 7, in use, except clamping jump ring 5 by flange 4, also can clamp jump ring 5 by through hole 7.
