Abstract

The utility model relates to an electric appliance, particularly an arbitrarily assembled bus insulating clamp, which comprises a left and a right side block which are sheathed on both ends of the clamping screw and a connecting component; the clamping screw between the insulating left and the insulating right side blocks is at least provided with an insulating clamping base and an intermittent block; one surface of each clamping base is provided with a pit, and the other surface is provided with a projection which can be matched with the pit on the other clamping base. Meanwhile, the both sides of the intermittent block are also respectively provided with a projection which can be matched with the pit and the projection, and the both sides of the intermittent block and the clamping base are also provided with a gap which can clamp a conductor on the clamping base.

Description

Assembled wire insulating clamp

The utility model relates to electric elements, specifically a kind of bus insulation folder that can combination in any.

Bus insulation spare is mainly used in the support of low-voltage distribution frame main bus bar and zero bus with fixing.Commonly used have bus insulation frame, a bus insulation frame etc., and this class component all can not single-phase combination and changed the thickness and the width of busbar arbitrarily, more can not be combined into single busbar or two busbars etc.Especially when maintenance, single-phase busbar still can single-phasely be changed after damaging, and female frame, bus-bar frame etc. just can not single-phasely be changed, in case damage, can only integral body change.

But the purpose of this utility model is a kind of combination in any of design bus insulation easy to maintenance presss from both sides, to overcome above-mentioned shortcoming.

Its main technical schemes comprises the left and right sides lateral mass (3) that is enclosed within clamping screw (8) two ends, (4) and connector, left and right sides lateral mass (3) in insulation, (4) have at least on the clamping screw between (8) insulation holder (5) and between piece (6), and the one side at each holder (5) has pit (13), another side has the projection (14) that can match with the pit (13) on another holder (5), and the breach (15) that can clamp electric conductor in addition on holder (5) with pit (13) and the projection that matches of projection (14) and pit is also arranged respectively in the two sides of a piece (6) equally.End at clamping screw (8) is equipped with magnetism isolating spacer circle (7).In the outside of left and right lateral mass (3), (4) the fastening frid in the left and right sides (1), (2) are arranged, and stretch out a fixing sole in frid (2) bottom, trip bolt (9) is arranged on the sole.

The utility model has the advantages that owing to be enclosed within to design on holder and the piece on the screw rod pit and projection are arranged, at the different busbar thickness of combination, it is convenient to be convenient to fixed combination when width, double, single main bus bar and zero bus, therefore, can press the number of a row folding seat and a piece as required.The copper bar of conduction is clipped between the breach of holder, and fail safe is better.One finds that certain holder has damage, only the holder that damages need be changed to get final product, and it is convenient especially to keep in repair.After the magnetism isolating spacer circle has been installed on the clamping screw, can prevent the eddy-current heating situation that bus clip produces, after being connected and fixed sole on the fastening frid, on-the-spot installation is quite convenient.

Fig. 1 is a structure chart of the present utility model.

As shown in the figure: overlap left and right fastening frid (1), (2) and left and right lateral mass (3), (4) at the two ends of clamping screw (8), make up some groups in the mode according to piece (6) between two holders (5), between left and right lateral mass (3), (4), folder conducting copper in the breach (15) of holder, the pit (13) and projection (14) that can cooperatively interact are arranged on left and right lateral mass (3), (4) and holder (5) and a piece (6), and screw rod (8) is fastening with pad (12), spring shim (11) and nut (10).The end of fastening frid (2) of keeping right on screw rod (8) is installed a magnetism isolating spacer circle (7), stretches out a fixing sole below frid (2), and trip bolt (9) is arranged on the sole.

Claims

1, composite type bus insulation folder, comprise a left side that is enclosed within clamping screw (8) two ends, right side block (3), (4) and connector, it is characterized in that a left side in insulation, right side block (3), (4) be with at least on the clamping screw between (8) insulation holder (5) and between piece (6), and the one side at each holder (5) has pit (13), another side has the projection (14) that can match with the pit (13) on another holder (5), the projection and the pit that can match with pit (13) and protruding (14) are also arranged respectively in the two sides of a piece (6) equally, on holder (5), can clamp the breach (15) of conductor in addition.

2, insulating blanked clamper according to claim 1 is characterized in that at an end of clamping screw (8) magnetism isolating spacer circle (7) being installed.

3, insulating blanked clamper according to claim 1 is characterized in that in the outside of left and right lateral mass (3), (4) left and right fastening frid (1), (2) being arranged, and a fixing sole is stretched out in fastening frid (2) bottom on the right side, and trip bolt (9) is arranged on the sole.
