A connector for low-voltage electric lines is composed of an upper cover, a bottom plate, a solid line clip, a mounting plate, a reed, connecting plates, a guard grating, a connecting piece, and a fixing piece. The connecting plates are arranged on the guard grating, and the guard grating is provided with guard grating ribs. The utility model is characterized in that the guard grating ribs on the outer sides of the two utmost outside connecting plates and both sides of the bottom plate are respectively and correspondingly formed one body. The utility model is used for low-voltage electrical apparatus.

Description

The low-voltage electrical line connector

The utility model relates to and is electrically connected device, refers to a kind of family expenses and similar applications low-voltage electrical circuit connector especially, generally claims binding post, also is terminal box.

The low-voltage electrical line connector that sell on the market now, uses as shown in Figure 1, its internal structure generally is arranged with four terminal blocks in its grille, all there is the grille muscle of grille each terminal block both sides, four terminal blocks have five grille muscle, not only volume is big, and promptly space availability ratio is lower, many consumable materials, the corresponding increase of cost, and terminal block quantity in the use; The number that is wiring point does not also apply application; At aspects such as material, serviceabilities, also still not ideal enough.

The purpose of this utility model is research, the test, on probation through the long duration, on this basis, above-mentioned original binding post is structurally improved, overcoming these shortcomings that exist, thereby provide a kind of new low-voltage electrical line connector that replaces original binding post of using.

The purpose of this utility model is achieved in that the low-voltage electrical line connector, it is made of loam cake, base plate, solidus clamp, binding, reed, terminal block, grille and connector, fixture, be arranged with terminal block on the grille, the grille muscle is arranged on the grille, it is characterized in that the grille muscle in outermost two terminal blocks outside and corresponding respectively the becoming one of two sides of base plate.

Above-mentioned design, at the same soleplate area, be under the onesize situation of terminal box, make the terminal block of on grille, arranging, can increase to five rows, the raising of materials used performance in addition from four original rows, its effect is not only little than the existing product volume, materials are economized, cost is low, main is that the wiring point number increases, and increases to 10 by original 8, can satisfy instructions for use better.

Below by drawings and Examples the utility model is described further again.

As shown in Figure 1: be arranged with four terminal blocks 107 on the grille, have 8 wiring points, all there is the grille muscle 1011 of grille each terminal block both sides, as seen from Figure 1, grille muscle 1011 has five, and its outermost grille muscle 1011 is split with two sides 1012 of base plate.

Shown in Fig. 2-6: the utility model is by loam cake 1, base plate 2, solidus clamp 4, binding 5, reed 6, terminal block 7, band grille muscle 10,10 ', 10 " grille and screw 3,8 and tapping screw 9 forms grille muscle outside its outermost two terminal blocks 11,11 ' and bar side 12,12 ' corresponding respectively the becoming one of base plate 2.

Shown in Fig. 2,4: the grille muscle between close two terminal blocks 7 at ground connection 14 places has been left out and this two terminal block 7 fuses, newly-designed like this binding post, and in fact the grille muscle of its grille has only three altogether.Its effect is to save 3 materials, has reduced cost.In addition, loam cake has been selected fire-retardant engineering plastics for use, and terminal block can be selected general steel plate or brass for use, and properties of product are further enhanced, and material is fully used.Through test, detect fully applicable to electric equipments such as refrigerator, refrigerator-freezer, device for beer on draft, make the usefulness of insulation, fixing and distribution, its technical conditions conform to fully.Fixing of IEC335-1 of International Electrotechnical Commission " safety of family expenses and similar applications electrical equipment " and international GB47061-92 " safety general of family expenses and similar applications electrical equipment requires " relevant binding post, and international standard IEC998-1, nineteen ninety, " the general requirement of family expenses and similar applications low-voltage electrical line connection device (being binding post or terminal box) " and IEC998-2-1, IEC998-2-2, IEC998-2-3,1991 " family expenses and similar applications low-voltage electrical line connection device (being binding post or terminal box) specific (special) requirements ".
