Abstract
The utility model discloses a kind of strain clamp.The technical problem solved is to provide a kind of dovetail groove cone wedged strain clamp not easily loosened.For solving the problem, the drainage plate that the technical solution adopted in the utility model comprises strain clamp body and is fixed on strain clamp body, in drainage plate one end, drainage tube is installed, it is characterized in that: described drainage plate both sides arrange symmetrical dovetail groove, described drainage tube both sides arrange the dovetail that has adapted with dovetail groove and carve limit, the cooperation of described dovetail wedge limit is embedded in the dovetail groove of drainage plate, then drainage plate and drainage tube is fixed by screw.Dovetail groove cone wedged strain clamp of the present utility model, is be connected with taper surface precision-fit with dovetail groove, under gravity, can locks voluntarily.Thoroughly solve the heating problem that drainage plate has loosened, also add the contact-making surface between drainage plate and drainage tube simultaneously, strengthen drainage effect.
Description
Technical field
The utility model relates to a kind of wire clamp, is specifically related to a kind of strain clamp.
Background technology
In transmission line, strain clamp and wire jumper generally adopt drainage plate to be connected.Drainage plate is under the effect of natural climate environment and load current, and aluminium sheet touch panel easily loosens, oxidation, thus causes the contact-making surface resistance of drainage plate to become large, and drainage plate generates heat.In order to ensure that power grid security is reliable, power department often must drop into a large amount of human and material resources and financial resources for this reason, carries out making regular check on and maintenance, and Thermal Infra-Red thermometric.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of dovetail groove cone wedged strain clamp not easily loosened.
For solving the problem, the drainage plate that the technical solution adopted in the utility model comprises strain clamp body and is fixed on strain clamp body, in drainage plate one end, drainage tube is installed, it is characterized in that: described drainage plate both sides arrange symmetrical dovetail groove, what the setting of described drainage tube both sides adapted with dovetail groove has dovetail wedge limit, the cooperation of described dovetail wedge limit is embedded in the dovetail groove of drainage plate, then drainage plate and drainage tube is fixed by screw.
Described strain clamp, is characterized in that: the dovetail groove of described drainage plate both sides is pyramidal structure wide at the top and narrow at the bottom, and what the setting of described drainage tube both sides adapted with dovetail groove has dovetail wedge limit.
Described strain clamp, is characterized in that: described screw is " one " word screw, and its lower end has " one " word portion, and the screw on described drainage plate and drainage tube is " one " word screw adapted with " one " word portion.
Described strain clamp, is characterized in that: described drainage tube front end has reinforcement lug boss.
Dovetail groove cone wedged strain clamp of the present utility model, is be connected with taper surface precision-fit with dovetail groove, under gravity, can locks voluntarily.Thoroughly solve the heating problem that drainage plate has loosened, also add the contact-making surface between drainage plate and drainage tube simultaneously, strengthen drainage effect.In the process of installing, simple and convenient, embedded after dovetail groove on dovetail wedge limit, drainage tube is substantially fixing, can tighten up a screw fixing, facilitate the installation and maintenance of electric power personal height, also ensured electric power personal height job safety simultaneously without the need to hand steered.This product also has long service life, reliably advantage in addition, reduces the maintenance of personnel, reduces great amount of cost.This product is applicable to high pressure, superhigh pressure, ultra high voltage and conventional steel-core-aluminium and cuts with scissors in the strain insulator drainage of the various plain conductors such as line, heat-resistant aluminum alloy wire, carbon fiber complex core twisted wire.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is exploded view of the present utility model.
Embodiment
As shown in Fig. 1 to 2, dovetail groove cone wedged strain clamp of the present utility model, the strain clamp body 1 comprising hollow and the drainage plate 2 be fixed on strain clamp body, in drainage plate one end, drainage tube 3 is installed, described drainage plate 2 bilateral symmetry arranges dovetail groove 4, what the setting of described drainage tube 3 both sides adapted with dovetail groove has dovetail wedge limit 5, and the cooperation of described dovetail wedge limit 5 is embedded in the dovetail groove 4 of drainage plate 2, then drainage plate 2 and drainage tube 3 is fixed by screw 6.
For optimizing such scheme further, the dovetail groove 4 of described drainage plate 2 both sides is pyramidal structure wide at the top and narrow at the bottom, and what the setting of described drainage tube 3 both sides adapted with dovetail groove has dovetail wedge limit 5.Arrange the dovetail groove of pyramidal structure, drainage plate and drainage tube can be locked voluntarily.
For optimizing such scheme further again, described screw 6 is " one " word screw, its lower end has " one " word portion 7, described drainage plate 2 is " one " word screw 9 adapted with " one " word portion with the screw on drainage tube 3, be equipped with by " one " word screw and " one " word screw 9, the rotation of screw may be prevented when crowded nut, further facilitate installation and maintenance.
Described drainage tube 3 front end has strengthens lug boss 8.Strengthen the mechanical strength that drainage plate is connected with drainage tube.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection range of the present utility model.
