Abstract
The present invention relates to a clamper for electric wires, which comprises a base clamping body 4, a movable clamping body 5, a spring 12, a fastening rod 14 and a push bolt 20, wherein the movable clamping body 5 is pivoted to the upper part of the base clamping body; the spring 12 is arranged in a space of the base clamping body; the fastening rod 14 penetrates through the top wall of the base clamping body and the spring; the push bolt 20 is arranged at the lower part of the base clamping body, and compresses the spring; the push bolt pushes the fastening rod to compress the spring, which causes the spring to be in a nonoperate state. The fastening rod is provided with a T-shaped head 21. When the spring does not work, the movable clamping body can be freely opened correspondingly to the T-shaped head. When the spring works, the movable clamping body and the T-shaped head are combined to clamp the electric wires by the elastic force of the spring.
Description
The present invention relates to clamping and send the device of electric wire, relate in particular to and to keep many conductors to send the electric wire accessory of baffle plate device that electric wire uses and vibration absorber (antivibrator) etc. to be installed in the clamper for electric wire of using on the electric wire with predetermined distance.
Always, sending electric wire used typical clamper for electric wire, is to clamp electric wire with a pair of clip halfbody, with fastening bolt that the clip halfbody is fastening again.
But, thisly apply the structure that tightening torque is come the clamping electric wire with fastening bolt, there is following shortcoming.That is, because there is individual differences in the operating personnel that apply tightening torque, so torque does not wait, clip unclamps and causes electric wire breakage, bolt falling to reach being difficult to aloft operate etc.
The object of the present invention is to provide a kind of clamper for electric wire of eliminating above-mentioned shortcoming.
Clamper for electric wire of the present invention, its characteristics are, comprise: base portion cramping body with semi-circular groove, be articulated in this base portion cramping body top and have relative with the groove of base portion cramping body, the movable cramping body of the semi-circular groove of clamping electric wire, be located at the helical spring in the space of base portion cramping body, run through the roof of base portion cramping body and the fastening rod of spring, be located at the bottom of base portion cramping body, the compression spring makes it be in the spring compression means of off position, be in free state in the time of can making movable cramping body be higher than fastening excellent top, or be incorporated into the coupling apparatus of fastening direction.
The characteristics of compression set are, comprise: with the packing ring of end in contact under the spring, be screwed into and be fixed on the nut of fastening excellent bottom, and the pushing bolt that is screwed into base portion cramping body diapire.
In addition, coupling apparatus comprises two branch parts of being located at movable cramping body, and the T font head of being located at fastening excellent top, when T font head is parallel with the groove of two branch parts, movable clamping physical efficiency is upwards rotated, when T font head and groove orthogonal configuration, since the elongation of spring, T font header suppression two branch parts.
Brief description:

Fig. 2 is the front view of clamper for electric wire of the present invention.
Fig. 3 is the cutaway view of clamper for electric wire of the present invention.
Fig. 4 is the vertical view of clamper for electric wire of the present invention.
Fig. 5 is the end view of clamper for electric wire of the present invention.
Following with reference to description of drawings one embodiment of the present of invention.Fig. 1 shows baffle plate device, and this baffle plate device comprises the dividing plate body 1 that is made of square framework, and by being connected four clamper for electric wire 3 of connecting bolt 2 installations of locating at four angles.
As Fig. 2, shown in Figure 3, clamper for electric wire 3 is made up of the base portion cramping body 4 and the movable cramping body 5 of aluminium alloy, at an end of cramping body 4, by pin 6, can be connected with to free opening and closing cramping body 5.Two cramping bodies have semicircular wiring duct 7,8, are tubular completely when two cramping bodies are closed substantially, and electric wire 9 is taken in these parts and is held.
Base portion cramping body 4 has the support 10 of U font and the installation portion 11 of two branches.Contain helical spring 12 in the space in support 10, fastening excellent 14 pass the hole 13 that is formed at the support roof and run through spring 12.In the lower end of spring 12, double nut 16,17 is twisted solid at 18 places, fastening excellent 14 threaded portion across packing ring 15.
On the other hand, on 6 diapires of support 10, be screwed with pushing bolt 20, the solid rod 14 of push-tight on this bolt, compression spring 12 makes it be off position.Fastening excellent 14 have T font head 21, its top by on push into two branch parts 22 that are higher than movable cramping body 5.
As Fig. 4, shown in Figure 5, the width W of T font head 21
1The width W of the groove of ratio two branch parts 22
2Little, when not in use, T font head is parallel with the groove of two branch parts.Therefore, movable cramping body 5 can be opened shown in Fig. 3 double dot dash line under the situation that can not run into T font head 21 like that.
As shown in Figure 1, each clamper for electric wire 3 is separately fixed on the terminal 23 that is fixed in dividing plate body 1 by connecting bolt 2 at installation portion 11 places.And each clamper for electric wire 3 is mounted in the posture that corona discharge can not take place each other.
The clamping action of electric wire below is described.As previously mentioned, movable cramping body 5 is opened shown in the double dot dash line among Fig. 3 like that, electric wire 9 is placed in the groove 7 of base portion cramping body 4.Then, making movable cramping body 5 is that the center rotates with pin 6, and groove 8 is resisted against on the electric wire 9 shown in the solid line of Fig. 3.Then, make fastening excellent 14 to rotate 90 degree, make two branch parts 22 of T font head 21, quadrature shown in the double dot dash line of Fig. 4 with respect to movable cramping body 5.
Then, if unscrew pushing bolt 20, then spring 12 stretches downwards, and pushes away downwards fastening excellent 14 by packing ring 15, double nut 16,17, and 21 beginnings of T font head contact with the top of two branch parts 22.Leave fastening excellent 14 lower end at last to pushing bolt 20, or unload the pushing bolt, spring 12 is stretched over to greatest extent, and T font head 21 is pressed two branch parts 22 with strong predetermined axis to trying hard to recommend, and can use effectively clamping electric wire 9 of the groove 7 and the groove Final 8.Again, in this clamp position, the lower limb of movable cramping body 5 does not contact with the upper surface of base portion cramping body 4.
When unloading electric wire, to carry out operation with above-mentioned opposite order.That is, be screwed into pushing bolt 20, upwards push away fastening excellent 14, compress spring 12 and advance.After lifting fastening excellent 14 on fully, make fastening excellent 14 to rotate 90 degree,, can unload electric wire movable cramping body 5 rotating opening.
If adopt the present invention, because be that the elastic force that utilizes the spring elongation to produce comes fastening electric wire, thus can be with certain axial force clamping electric wire of regulation, tightening torque can be not variant, reliably the clamping electric wire.Because be to unscrew the pushing bolt only,, also can carry out safely aloft again so power that need not be big can easily be operated.Have again, because can as bolted, can not unclamp, so clamper for electric wire highly reliably can be provided.
