Abstract

The utility model discloses a rapid terminal box which comprises a box body. Metal conducting sheets and jump rings are disposed in the box body. The cross section of each jump ring is C-shaped, and the opening of the jump ring is facing upward. Two sides of the opening of each jump ring are respectively provided with a through hole. The side edges of each jump ring are respectively provided with a clamping hole. One end of each metal conducting sheet bends to form an accommodating cavity which corresponds to each jump ring. Each jump ring is placed in the accommodating cavity. The inside wall of the accommodating cavity of each metal conducting sheet is provided with protrusions to form a clamping end which is mated with the clamping holes of the jump ring. The rapid terminal box is convenient in manufacturing, simple in operation for insertion of bus bars, and exhibits a fine wiring effect.

Description

Quick connector

Technical field

The utility model relates to a kind of quick connector, comprises box body, is provided with metallic conduction sheet and jump ring in the box body.

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 electric energy, each group solar module is connected with terminal box, terminal box is connected with other parts of solar power system again, because the 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 efficient 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.The 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 vertical edges and a free end that has a rectangular opening, the front end cutting ferrule of rectangular opening is fixed on the outer vertical edges at conducting strip indent position, the vertical edges of flexure strip is posted by on the medial surface at conducting strip indent position, by wedge tool the vertical edges of flexure strip and the medial surface of conducting strip are opened, thereby fill in busbar, unclamp wedge tool, busbar can be sandwiched between the two, the conducting strip rear portion is to be embedded in the junction block, in order to improve the 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 has careless mistake slightly, will influence the wiring effect; The vertical edges of flexure strip abuts on the medial surface of outer vertical edges at conducting strip indent position in addition, and the free end of flexure strip and should outer vertical edges fixing, and is therefore relatively difficult when the use wedge tool is separated the vertical edges of flexure strip and conducting strip.

Summary of the invention

The purpose of this utility model provides the simple terminal box of a kind of technology, engages easily with busbar, and engages effective.

For this reason, the technical solution adopted in the utility model is such: quick connector, comprise box body, and be provided with metallic conduction sheet and jump ring in the box body, the jump ring cross section is " C " shape and opening makes progress, and the opening both sides respectively have a through hole, and the jump ring side respectively has a connecting hole; 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 madial walls respectively have a projection to form a fastening end, cooperate with the connecting hole of jump ring.

As further improvement, a flange that makes progress is arranged respectively between jump ring opening and two side through hole.

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

In addition, described fastening end also can be the inclined-plane that is upturned, and bevel direction is parallel to the opening direction of accommodation aperture, and fastening end, inclined-plane, both sides direction is identical.

During installation, make the opening of jump ring corresponding with the opening of metallic conduction sheet accommodation aperture, push away jump ring from metallic conduction sheet side and enter accommodation aperture, the connecting hole of jump ring bottom and the fastening end, inclined-plane in the accommodation aperture are fastened togather, firmly engage jump ring and metallic conduction sheet, loosening about preventing between the two, after jump ring was pushed into accommodation aperture, the both sides of jump ring were near the front and back inwall of accommodation aperture.Metallic conduction sheet of the present utility model is preferably four tooth shape ends at the end that stops that its accommodation aperture upper end is provided with, and near the upper surface of jump ring, these four tooth shape ends do not cover the through hole of jump ring upper surface, and be in the side of jump ring upper surface flange, because the distance between the upper surface of tooth shape end and jump ring is very little, jump ring can not be taken out from the top, comes off from the accommodation aperture top so can prevent jump ring.

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

The utility model 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 makes progress, and side respectively has a connecting hole 6, and upper surface open both sides correspondence respectively is with a through hole 7.Referring to Fig. 3, metallic conduction sheet 1 front end has accommodation aperture 2, size and jump ring 5 couplings, and the upper end-face edge of accommodation aperture 2 extends four detiform ends 4 that stop, stops that end 4 is parallel with the bottom surface of accommodation aperture 2; Two madial walls of accommodation aperture 2 respectively have fastening end, an inclined-plane 3, and the opening direction of fastening end, inclined-plane 3 is parallel with accommodation aperture 2 lateral opening directions, and fastening end, two inclined-planes 3 directions are identical mutually; The madial wall of accommodation aperture 2 possesses friction rib 9.

Referring to Fig. 1 and Fig. 4, metallic conduction sheet 1 is contained in the box body 8 with jump ring 5, during assembling, jump ring 5 from fastening end, inclined-plane 3 not a thruster of opening go into accommodation aperture 2, fastening end, inclined-plane 3 embeds the connecting hole 6 of jump rings 5 at this moment, stop that simultaneously end 4 blocks jump ring 5 in the upper end, makes jump ring 5 be fixed in the accommodation aperture 2 jointly.During use, only need to use instrument, as pliers, insert two through holes 7 and clamping on the jump ring 5, can produce the gap between the sidewall of jump ring 5 and accommodation aperture 2, in the gap, insert busbar, unclamp jump ring 5 then, jump ring 5 promptly can clamp busbar with the madial wall of accommodation aperture 2.

Embodiment 2
