Technical field
The present invention relates to the terminal box in a kind of electric component, particularly relate to the terminal box that a kind of solar module connects usefulness.
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 converts daylight to electric energy, each group solar module is connected with terminal box, terminal box is connected with the 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.
The butted line box has had many technical schemes in the prior art, discloses a kind of terminal box of capable of being combined and dismounting in the patent No. is 03232075.2 Chinese patent " quick connector " as the inventor.As further improvement, the inventor discloses another kind of " terminal box " in the patent No. is 200720106882.5 Chinese patent, it includes metal connecting piece on box body, lid, the junction block, wiring joint, it is characterized in that: described junction block is to be distributed in successively on the box plate, form jack on the junction block, metal connecting piece is mounted on the junction block by pin; Described metal connecting piece is in the middle front part perforate, and back side welded nut is threaded for screw and pad.Practice is used and is shown that also there is improved necessity in this terminal box, because box body lacks cable fixture, the long-time use, cable is easily loosening or arch upward in box body, thereby causes loosening between cable and the metal connecting piece or come off, and directly influences the result of use and the fail safe of terminal box; Also have the metal connecting piece structure too simple, cable is connected on the metal connecting piece, causes situations such as loose contact, screw become flexible easily.
Summary of the invention
The purpose of this invention is to provide the fixing more convenient reliable terminal box of a kind of cable.
For this reason, the present invention has adopted following technical scheme: a kind of terminal box, comprise box body, lid, metal coupling assembling, cable briquetting, sealing plug, line clamped block, box body and lid fasten by buckle, be provided with junction block and metal coupling assembling in the box body, it is characterized in that: it also comprises a cable briquetting, described cable briquetting left-right symmetric, top cracking in the middle of it, only in the bottom adhesion, thus about making two sections can be folded into different angles; Two sections respectively have a semi-circular arch hole about the cable briquetting, and two ends are the staged fastening end; The box plate front end is provided with two pits, cooperates with the semi-circular arch hole of described cable briquetting, forms the appearance line hole of ccontaining cable; Box plate front end both sides also are provided with two fixture blocks, cooperate with the staged fastening end at cable briquetting two ends.
As further improvement, there is hole the centre of described cable briquetting, with screw it is fastened on the box plate.
Further improve, described sealing plug is a trapezoidal cylinder again, adopts silica gel material to make, inwall moulding circular hole passage, and cock body faces inner close fitting wiring hole inwall by minor radius and fills in.
Further improve, described line clamped block is a square plastic fixture block, and small sircle hole is opened in the centre; The bottom surface is level and smooth, is distributed with several small-sized card bases with two sides, the left and right sides above, and box body front connection hole outer periphery has square draw-in groove, snaps in for line clamped block.
Technical scheme further below the present invention also can adopt: the metal coupling assembling is made of the metal hole clipping that the metal card base of last brace snaps in down brace, is fixed on the junction block.Junction block is provided with a hexagonal containing hole, is built-in with a nut; Last brace and following brace center drilling are fixed in by screw on the nut of junction block.
The present invention in use, the cable briquetting is pressed on the box plate, the semi-circular arch hole of cable briquetting and the pit of box plate form the appearance line hole of ccontaining cable, and cable is compressed, and make it stiff; The middle upper portion of cable briquetting cracking, the bottom adhesion, like this about two sections just can do amounting to of certain angle; When angle is big, about the air line distance of two end points just nearer, the staged fastening end of cable briquetting can be stretched in the fixture block of box plate, when angle hour, about the air line distance of two end points far away, this moment, the staged fastening end utilized its elastic force and fixture block to be fixed.When the cable briquetting progressively being compressed with screw, promptly be that cable briquetting angle becomes greatly gradually, the process that two ends air line distance is elongated gradually also is the process that cable is compressed gradually simultaneously.
Compared with prior art, the invention has the advantages that: this junction box structure is simple and practical, and parts are few, and is easy to loading and unloading, and fixing of cable is more firm, more convenient, more reliable; Line clamped block can prevent coming off of sealing plug, also cable is inserted box body and plays better fixation; Sealing plug has been strengthened the waterproof sealing effect of box body especially, makes the use of terminal box safer; The metal coupling assembling has been strengthened and being connected of cable, more obviously the wiring effect of outstanding metal coupling assembling.
