Description

Low-voltage electrical control cabinet postposition type electric cable assembly

The utility model relates to a kind of low-voltage electrical control cabinet postposition type electric cable assembly, relates to a kind of major loop termination of electric control box.

At present the low-voltage electrical control cabinet generally adopts the cable assembly of horizontal outlet, this cable assembly is installed after, the cabinet width of its electric control box must be provided with 1000mm, comprising drawer function unit 600mm, the 400mm of cable vault.Its whole group control cabinet of the electric control box of this major loop outlet structure is arranged broad, if the user will install electric control box on original narrower power distribution room place, just has to reduce the capacity in whole power distribution room loop.In old distribution project reconstruction, especially under the situation that can not increase the power distribution room place, go out line method with this major loop, be the capacity that can't increase electric control box.In the wide drawer function unit of 600mm cabinet of the original design of our factory,, reduced the space in the drawer and the installation site of drawer elements, limited the condition of selecting for use of element because major loop turnover line all is positioned on the same horizontal line of drawer.

The purpose of this utility model is to provide a kind of low-voltage electrical control cabinet postposition type electric cable assembly to the user, make the low-voltage electrical control cabinet that this postposition type electric cable assembly is installed after, can improve the utilance of power distribution room effectively.

The utility model adopts such technical scheme: this low-voltage electrical control cabinet is by cable contact with the postposition type electric cable assembly, joint cover is connected cover three parts and assembles with insulation, cable contact comprises pedestal and bank of contacts, one end of this bank of contacts is for patching end, the other end is a link, joint cover also comprises pedestal and bank of contacts, one end of this bank of contacts is a link, the other end is terminals, bank of contacts link on the cable contact and joint cover upper contact head row link are fastening mutually, and connect cover cap with insulation and live this connecting portion, be characterized on the cable contact patching end and terminals on the joint cover lay respectively at cabinet before, back two ends; It is orthogonal with link that bank of contacts in the cable contact patches end, the link and the terminals of the bank of contacts in the joint cover are parallel to each other, and it is perpendicular with the two line, after bank of contacts connects into, begin after the terminals of joint cover are turned through three 90 ° of angles, behind cabinet, to produce from the end that patches on the cable contact; There is a concavo-convex fixed handle on the right side of cable contact, and it is connected with the coil holder that goes out of cable assembly; The thickness of described joint cover is no more than 24mm.

The utility model is because the patching end on the cable contact lays respectively at the forward and backward two ends of cabinet with terminals on the joint cover, after like this cable vault being transferred to cabinet, thereby the electric control box drawer feeder number in the 600mm width that guarantees this cable assembly of installation is constant, thereby effectively reduce the electric control box spread length, greatly reduce manufacturing cost.

Accompanying drawing is a kind of embodiment of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, this low-voltage electrical control cabinet is mainly assembled by cable contact 1, joint cover 2, insulation connection cover 3 three parts with the postposition type electric cable assembly.Cable contact is formed by pedestal 10 and bank of contacts 11 single injection-moldeds, one end of bank of contacts 11 is for patching end 4, the other end is a link 5, patching end 4 can patch with the contact in the drawer rear wall 6, and joint cover 2 is also formed by pedestal 15 and bank of contacts 16 single injection-moldeds, and an end of bank of contacts 16 is a link 7, the other end is terminals 8, two links 5,7 are fastening by screw, connect cover 3 with insulation then and cover connecting portion, make it insulation.The end 4 that patches of cable contact 1 lays respectively at the forward and backward two ends of cabinet with terminals 8 on the joint cover 2.Bank of contacts 11 patches end 4 certainly and begins to produce terminals to terminals 8 through three right-angled bends behind cabinet with after bank of contacts 16 is connected.The wide drawer function unit of 600mm left side C type post 13 is extruded the 25mm space in 1000mm width electric control box like this, and the thickness of this joint cover 2 is no more than 24mm, with guarantee cable assembly in the 25mm space width backward 90 ° of angles produce.

As shown in Figure 2, have two installing holes 12 on the pedestal 10, so that the postposition type electric cable assembly is fixed on the electric control box C type post 13 with screw.For three utmost points, sextupole inlet wire, terminals generally become in-line to arrange.Among Fig. 5, bank of contacts 11 1 ends are to patch end 4 and the other end is link 5, a concavo-convex fixed handle preferably arranged on the right side of cable contact 1, it can go out coil holder 14 with screw and cable assembly and be connected, can both reach original designing requirement like this, guarantee again that this electric product patched performance reliably.

As shown in Figure 3.Joint cover 2 is also formed by pedestal 15 and bank of contacts 16 single injection-moldeds.For three utmost point outlets, terminals 8 are isosceles triangle or in-line to be arranged, and for six grades of outlets, arrangement that 8 one-tenths two of terminals are listed as and contact misplaces mutually is to prevent to produce creepage phenomenon.Among Fig. 6, the link 7 of bank of contacts 16 parallels with terminals 8, and perpendicular to the two line.

As shown in Figure 4, also have 2 installing holes 19 in the insulation connection cover 3.And from the plane of insulation connection cover, extend lug 20, so that strengthen the creepage distance of bank of contacts.

Pedestal 10 in the cable assembly and pedestal 15 all adopt the high-strength anti-flaming engineering plastics to make.
