Abstract

The utility model relates to a branch or combined wiring device of a multi-core cable. In the utility model, flanges and bolts of the box bottom and a cover casing are connected and clamp a sealing ring to form a sealed box body, a triangle bracket inclined plane arranged on the upper part of the box bottom is provided with a wiring terminal row whose obverse face inclines backward, and the wiring terminal row is naked in the space arranged above an opening of the box bottom, which brings convenience to installation and maintenance; the lower part of the box bottom is provided with a cable sealing pipe head; the side wall of the triangle bracket on the upper part is provided with a cable clamp; after penetrating into the box body, a cable is clamped by the cable sealing pipe head and the cable clamp, thus, ensuring that a branched core wire and the wiring terminal row are free of the influence of destructive mechanical stress.

Description

The binding post case

The utility model relates to a kind of branch or composite set of multicore cable.

The branch of heart yearn or combination are to be finished by the connecting terminal block in the binding post case in the multicore cable.Because Effect of Environmental, so the selection of pair of wire connection terminals case and seal request are strict especially, heart yearn connects any destructive mechanical stress that must not bear behind the connecting terminal block simultaneously.Previously used two kinds of products of the same type, first kind is to fold in the square box casing that forms with sheet iron to put connecting terminal block, volume is big, complex process, sealing property do not reach requirement, another kind is columnar terminal box, put with spiral shell between chassis and the case and be connected, screw screw thread and compress sealing ring, so just make sealing ring when being subjected to normal pressure, be subjected to the influence of spin friction power again, sealing ring destroys easily, it is too little that the terminal board support of this product is erected to be welded on the chassis solder side, insecure, cable also can't be fixed in the casing.

The purpose of this utility model be to overcome prior art not enough and provide that a kind of volume is little, easy to operate, good seal performance and cable being securely fixed in the casing, the binding post case that heart yearn and terminal board are not influenced by other destructive mechanical stress can reach anticorrosion, antidetonation effectively.The utility model also is more satisfactory version for explosion-proof, radioresistance when selecting suitable material and size for use.

The purpose of this utility model is achieved in that the binding post case has at the bottom of the short columnar case and high columnar case, is connected with flange and bolt at the bottom of the case and between the case and clamps the casing that sealing ring constitutes a sealing.A leg-of-mutton support is installed on top at the bottom of the case, the terminal board back side is installed on the inclined-plane of support, make the terminal board front recede and all expose in the space and just expose on the opening at the bottom of the case, this installation form is convenient to the operation and the inspection of line, the cable tube head interts at bottom half, strain relief clamp is installed on the both walls of triangular supports, make working cable through cable tube head and strain relief clamp double fixed chucking, mounting bracket is welded in the lower end and the side of casing, and the back side of mounting bracket and bottom be the installation and processing slot respectively.

The utility model has the advantages that in sum: the volume of binding post case is little, the saving space, and positive sweptback connecting terminal block is convenient to operation, and cable is firm at binding post case internal fixation, and heart yearn is not influenced by external force, and sealingly secure, installation maintenance are conveniently.

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

Fig. 1 is the side sectional view of the utility model binding post case.

Fig. 2 is the vertical view cutaway drawing of binding post case shown in Figure 1.

Structure such as Fig. 1 of the utility model binding post case are shown in Figure 2, at the bottom of the case 1 and case 2 between flange 3,4 are connected with bolt 6, when screwing bolt 6, just compress sealing ring 5, constitute the casing of a sealing, triangular supports 7 is installed on 1 top at the bottom of case, the back side of connecting terminal block 8 is installed on the inclined-plane of triangular supports 7, make the front of terminal board 8 recede, the space that the working portion of connecting terminal block 8 all exposes again on 1 opening at the bottom of the case is convenient to install, maintenance, cable 9 penetrates in the casing through the through hole of the cable tube head of cable seal tube head body 12 fillers 13 and gland nut 14 compositions, screws gland nut 14 and makes filler 13 embrace cable 9 tightly.Strain relief clamp 10 is the cables 9 that are used for compressing after penetrating at the bottom of the case, tightening screw 11 is pressed on cable 9 on the side wall of triangular supports 7, so just guaranteed that cable 9 installs firmly in terminal box, heart yearn is not influenced by external force after connecting terminal board 8, casing has reliable sealing performance, can defend pernicious gas and liquid effectively.

Mounting bracket 15 has a horizontal edge to be welded at the bottom of the case bottom, two vertical edges of 1 to be welded at the bottom of the case on 1 the side wall, leave respectively at the bottom of mounting bracket 15 and back that so no matter slot 16,17 is laterally installed or vertically installation can both reach safe ready.

The utility model binding post case is divided into the nonmetallic materials except that sealing ring 5 fillers 13 and terminal board 8 middle parts, and other parts are all formed by the metal material manufacturing.

Claims

1. binding post case, it is characterized in that: at the bottom of the case 1 and case 2 between with flange 3 and flange 4 bolts 6 sealing rings 5, constitute the casing of a sealing, one triangle terminal board support 7 is being installed on 1 at the bottom of the case, connecting terminal block 8 is installed in again on the inclined-plane of triangular supports 7, the two sides of triangular supports 7 are equipped with strain relief clamp 10, and the lower end at the bottom of the case is equipped with cable tube head and the mounting bracket of being made up of cable tube head body 12 fillers 13 and gland nut 14 15.

2. binding post case according to claim 1, it is characterized in that: casing is cylinder.

3. binding post case according to claim 1 is characterized in that: connecting terminal block 8 on the inclined-plane of triangular supports 7 positive recede and high outlet at the bottom of expose in the space on 1 the opening.
