Abstract
The utility model relates to a cuneate insulation strain clamp which is used for clamping insulated cables, bare conductors or communication cables. Both sides of a casing are respectively provided with a thread hole and pin holes, the both sides of a casing are respectively matched with a connecting plate, a cylindrical pin with threads passing through a connecting hole of the connecting plate is screwed in the thread hole of the casing, and a locking pin is respectively inserted into each pin hole. The utility model has the advantages that the casing 1 can follow with the conductor to swing when the clamped conductor vibrates up and down because of the blowing action of the wind, and the connecting plate 5 is not influenced; thus, the impact force can be eliminated to act on the casing, and the reliability that the conductor is tightly clamped by the utility model can be improved.
Description
The utility model relates to a kind of wedge shape strain clamp that is used for clamping insulated cable, plain conductor or communication cable.
Existing wedge shape strain clamp primary structure is a wedge shape housing, the syndeton of it and cross-arm, insulator or other fixture is two ends to be had the excessive U-shaped round steel ring termination of pier embed in the circle hole groove of housing both sides, is joined with cross-arm, insulator or other fixture by U-shaped round steel ring again.In the use, the lead wind-engaging of institute's clamping blows and up-down vibration, and housing is produced impulsive force.U-shaped round steel ring two front ends that pier is excessive and the circle hole groove of housing both sides are very easily killed, and can bend the scarf of circle hole groove and round steel ring two front ends when housing is subjected to impacting repeatedly, cause that circle hole groove breaks, round steel ring termination comes off and cause line accident.
The utility model is that the syndeton of above-mentioned wedge shape strain clamp and cross-arm, insulator or other fixture is improved, the impulsive force that adopts movable connection structure to eliminate that the lead wind-engaging blows and housing is produced during up-down vibration, improve the reliability of wire clamp, avoid line accident the lead holding.
A kind of wedge shape strain clamp of the utility model has a wedge shape housing, it is characterized in that: a screwed hole is respectively offered in the housing both sides, and is respectively equipped with pin-and-hole on each screwed hole vertical direction and communicates with screwed hole; A connecting plate is respectively joined in both sides, and an end of each connecting plate is provided with a connecting hole; The connecting hole screw-in housing of connecting plate is respectively passed in both sides with a cylindrical pin with external thread screwed hole inserts a stop pin respectively and is butted on cylindrical pin with external thread in each pin-and-hole.
Be further described below in conjunction with embodiment of the present utility model and accompanying drawing thereof.
Fig. 1 is the utility model embodiment one syndeton schematic diagram.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the utility model embodiment two syndeton schematic diagrames.
Because of remaining structure among the utility model embodiment identical with existing wedge shape strain clamp, accompanying drawing only provides the structure of itself and cross-arm, insulator or other fixture (all not shown among the figure) joining part, this joining part left-right symmetric, shown in the drawings is the structure of a side.
Fig. 1, wedge shape strain clamp embodiment one shown in Figure 2 have a wedge shape housing 1, and it is characterized in that: a screwed hole 2 is respectively offered in housing 1 both sides, and are respectively equipped with pin-and-hole 4 on each screwed hole 2 vertical direction and communicate with screwed hole 2; A connecting plate 5 is respectively joined in both sides, and an end of each connecting plate 5 is provided with a connecting hole 7; Each passes the screwed hole 2 of the connecting hole 7 screw-in housings 7 of connecting plate 5 both sides with a cylindrical pin with external thread 6, cylindrical pin with external thread 6 this as connecting plate 5 on the turn axle of connecting hole 7, insert a stop pin 3 in each pin-and-hole 4 respectively and be butted on cylindrical pin with external thread 6,6 rotations of restriction cylindrical pin with external thread are deviate from.Housing 1 bore clamping lead, connecting plate 5 is connected with cross-arm, insulator or other fixture, and lead is just erected.
Fig. 3 is the utility model embodiment two, and housing 1 has thicker wall, respectively establishes a storage tank 8 on its both sides and each screwed hole 2 vertical direction, and each connecting plate 5 lays respectively in each storage tank 8, and other structure is identical with embodiment one.
The utility model has the advantages that: housing 1 is connected with connecting plate by the axis hole connection, when clamping lead Wind-engaging blows and during up-down vibration, housing 1 is swung thereupon, and connecting plate 5 is also unaffected, so namely disappears Except the lead wind-engaging blows and the impulsive force that housing produced during up-down vibration, improve wire clamp to the lead holding Reliability.
Claims (2)
1. a wedge shape strain clamp has a wedge shape housing, it is characterized in that: a screwed hole is respectively offered in the housing both sides, and is respectively equipped with pin-and-hole on each screwed hole vertical direction and communicates with screwed hole; A connecting plate is respectively joined in both sides, and an end of each connecting plate is provided with a connecting hole; The connecting hole screw-in housing of connecting plate is respectively passed in both sides with a cylindrical pin with external thread screwed hole inserts a stop pin respectively and is butted on cylindrical pin with external thread in each pin-and-hole.
2. wedge shape strain clamp according to claim 1 is characterized in that: respectively establish a storage tank on housing both sides and each the screwed hole vertical direction, described each connecting plate lays respectively in each storage tank.
