when the fastener 30 is connected with the upper splint 10 and the lower splint 20, the first upper groove 101 and the second upper groove 102 correspond to the first lower groove 201 and the second lower groove 202, and respectively enclose to form a first wire clamping hole and a second wire clamping hole;
the upper clamping plate 10 is provided with a long hole 104, and the fastener 30 is arranged in the long hole 104 in a penetrating manner; when the fastening member 30 is loosened from the upper and lower clamping plates 10 and 20, the upper clamping plate 10 can be moved to adjust the size of the first and second clamping line holes.
According to the torque-locking wire clamp, the long hole is formed in the upper clamping plate or the lower clamping plate, when the fastener is connected with the upper clamping plate and the lower clamping plate, the fastener penetrates through the long hole, and then when the fastener is loosened from the upper clamping plate and the lower clamping plate, the upper clamping plate or the lower clamping plate can move, and the sizes of the first wire clamping hole and the second wire clamping hole are adjusted through movement; when the moment tight wire clamp needs to clamp two wires with different wire diameters, the upper clamping plate or the lower clamping plate can deflect towards the wire with the smaller wire diameter, so that the first wire clamping hole and the second wire clamping hole are different in size, and the moment tight wire clamp is suitable for clamping the two wires with different wire diameters.
Specifically, the fastener 30 includes a bolt 31 and a nut 32; wherein, the bolt 31 passes through the upper and lower clamping plates and clamps the upper and lower clamping plates together with the nut 32.
Preferably, as shown in fig. 1 to 4, the upper surface of the upper clamping plate 10 is a circular arc surface.
The moment fastening wire clamp also comprises a connecting backing plate 40 arranged between the upper clamping plate and the nut, wherein the upper surface of the connecting backing plate 40 is a plane, and the lower surface of the connecting backing plate 40 is an arc surface;
wherein, the lower surface of the connecting pad 40 and the upper surface of the upper plate 10 correspond to each other.
In the torque-locking wire clamp of the embodiment, the upper surface of the upper clamping plate is an arc surface, and a connecting base plate is arranged between the upper clamping plate and the nut; the upper surface of the connecting backing plate is a plane, so that the connecting backing plate is always in surface contact with the nut; the lower surface of the connecting backing plate is an arc surface, so that the connecting backing plate can be always attached to the upper surface of the upper clamping plate under the condition that the upper clamping plate is inclined, the upper clamping plate can be inclined towards one side of the upper clamping plate when being deviated, a small wire clamping hole is smaller, a large wire clamping hole is larger, and the fastening piece can ensure that the upper clamping plate and the lower clamping plate are clamped tightly through the pressing connecting backing plate.
Preferably, as shown in fig. 3, a third groove 103 is connected between the first and second upper grooves 101 and 102, and the third groove 103 is used for avoiding a protrusion of an inner side edge of the first and second lower grooves 201 or 202.
It should be noted that a third groove may also be provided between the first and second lower grooves for avoiding a protrusion at the inner edge of the first or second upper groove.
As shown in fig. 4, if the third groove 103 is not provided between the first and second upper grooves 101 and 102, an interference area 50 is easily generated between the upper and lower clamping plates when the upper clamping plate 10 is shifted and inclined; the larger wire-clamping hole is larger than in fig. 5 due to the presence of interference zone 50, and therefore it is likely that a thicker wire cannot be clamped.
Preferably, as shown in fig. 5, a fourth groove is provided on the lower surface of the lower clamping plate 20;
the screw rod 31 penetrates through the lower clamping plate from the fourth groove, and the head of the screw rod 31 is clamped in the fourth groove.
Preferably, the inner wall of the fourth groove clamps the head of the screw 31 to prevent the screw 31 from rotating relative to the lower plate 20.
It should be noted that, in the actual production, the upper and lower overtime work are made of metal, and most of the overtime work is aluminum alloy; when the fourth groove of the lower clamping plate is manufactured, the width of the fourth groove is slightly larger than the head of the bolt; after the head of the bolt is clamped into the second groove, the corresponding part of the fourth groove is deformed inwards by means of hot pressing and the like, so that the inner wall of the fourth groove clamps the head of the bolt.
The moment tight fastener of this embodiment presss from both sides the head of bolt through the fourth recess to when connecting upper and lower splint, when turning round the bolt with the nut, the bolt can not rotate, thereby does not need to hold the bolt with the hand in addition, and is more convenient to the connection of electric lines work that often needs at high altitude construction.
Specifically, as shown in fig. 1 to 3, the first and second upper grooves and the first and second lower grooves are provided with anti-slip stripes.
Preferably, as shown in fig. 6 and 7, the nut 32 includes a first rotating portion 321, a connecting sheet 323, and a second rotating portion 322 connected in sequence;
a threaded hole 3221 for connecting the screw 31 is arranged in the second rotating part 322;
when the first rotating portion 321 and the second rotating portion 322 rotate relative to each other, the connecting sheet 323 is twisted off.
In the torque-lock cable clamp of the embodiment, the nut comprises a first rotating part, a connecting sheet and a second rotating part which are sequentially connected; during wiring, a wrench or other tools are used for driving the first rotating part to rotate, so that the second rotating part is driven to be screwed into the bolt through the threaded hole of the second rotating part; when the nut assembly presses the connecting gasket or the upper clamping plate, the second rotating part rotates relative to the first rotating part due to resistance, and the connecting thin sheet is twisted off due to torsion; this means that the upper clamping plate has been compressed tightly by the nut, and the operating personnel need not to screw the gland nut further to avoid the electric wire by upper and lower clamping plate clamp excessively tight, cause too big damage.
In this embodiment, the first rotating part is a hexagonal bolt head, and the connecting thin slice is a circle of circular thin slice connected to the hexagonal bolt head; in actual production, the first rotating part, the connecting sheet and the first rotating part are integrally molded.
The second rotating part is a hexagonal bolt head identical to the first rotating part.
Preferably, an isolation rubber ring 324 is further sleeved on the outer side of the connecting sheet 323.
In order to avoid that when the nut is screwed into the bolt for the first time and the upper and lower clamping plates are pressed tightly, an operator clamps the first rotating part and the second rotating part simultaneously by using a wrench, an isolation rubber ring is required to be arranged on the outer peripheral part of the connecting sheet to play a role of separating the first rotating part from the second rotating part, so that the operator cannot clamp the first rotating part and the second rotating part simultaneously by using the wrench; in addition, in order to avoid the connecting sheet from being damaged in a non-working state, the isolating rubber ring can play a role of buffering when the connecting sheet is impacted.
In addition, various embodiments or examples and features of various embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
