Description

A kind of Anti-drip parallel groove clamp

Technical field

The utility model relates to technical field of power systems, and in particular to a kind of Anti-drip parallel groove clamp.

Background technique

When power load (such as electricity box or connecting terminal) using insulated conductor in the offline connection of overhead transmission line, generally use Parallel groove clamp, conducting wire the end of a thread are accessed on conducting wire by parallel groove clamp, since power load is typically in lower than overhead transmission line, are such as schemed Shown in 1, wiring conducting wire is tilted down along parallel groove clamp after wiring connect with power load, since the metal of the end of a thread of conducting wire is fine There are gaps between core and plastic cord skin, and when encountering rainy day, rainwater is easy under the effect of gravity along such as after dripping at the end of a thread Direction shown in Fig. 2 arrow entered inside conducting wire by the insulating layer of conducting wire downwards or eventually entered in the presence of hydraulic pressure electricity box into The connecting part of cable brake knife, the corrosion of rainwater will cause the oxidation open circuit of the equipment such as conducting wire, plug-in strip, and serious person causes ground connection, short circuit, draws Play personal safety and safety of property.

Utility model content

In view of the shortcomings of the prior art, the utility model provides a kind of Anti-drip parallel groove clamp, by installation positioning pipe and Locating sleeve cooperation, makes the end of a thread of conducting wire when connecting with power load, by a deflecting, so that rainwater cannot be introduced into conducting wire Inside, and then solve because of situations such as rainwater intrusion conducting wire leads to equipment oxidation open circuit generation.

The utility model is achieved by the following technical solution:

A kind of Anti-drip parallel groove clamp is provided, including two clamping plates being detachably connected, is formed with and is used between two clamping plates The clamp chamber of conducting wire and both ends open is clamped, at least one opening of clamp chamber, which is connected with, to be passed through for conducting wire and by conducting wire along clamping plate The guide pipe that plane alters course upwards.

For one rear line head of conducting wire after parallel groove clamp accesses overhead transmission line, the other end makes conducting wire after penetrating guide pipe Guide pipe is pierced by after changed course upwards and the power load of lower section connects, so that conducting wire forms the shape for being similar to wave crest, is made in this way Rainwater after the conducting wire the end of a thread for soaking parallel groove clamp will not along the connecting part for flowing downwardly to electricity box inlet wire plug-in strip inside conducting wire, Lead to the oxidation open circuit of the equipment such as plug-in strip so as to avoid conducting wire water inlet, improves equipment safety in utilization.

Further, the clamp chamber is fixed with locating sleeve in opening and is connected by locating sleeve and guide pipe It connects.

Locating sleeve and guide pipe cooperate, and can be used for a long time without deforming, and help to ensure that the steady of structure entirety It is qualitative.

Further, the guide pipe include guide flat pipe and with the integrally formed guiding inclined tube of guide pipe, guide pipe Pass through guide flat pipe and locating sleeve grafting.

The guide flat pipe of guide pipe can be mating with locating sleeve, so that guide pipe is installed on parallel groove clamp, leads Xiang Pingguan can draw conducting wire from parallel groove clamp, and guiding inclined tube for altering course the conducting wire of extraction upwards, so that the end of a thread of conducting wire Place remains downwards with insulating layer, can avoid preventing danger caused by the corrosion because of rainwater in rainwater intrusion conducting wire in this way Evil.

Further, the guide flat pipe is convexly equipped with retention bead in the end that it connect with locating sleeve, described Positioning groove engaged therewith is equipped in locating sleeve.

Positioning groove cooperation in the retention bead and locating sleeve of guide flat pipe, it is ensured that guide pipe and parallel groove clamp The stability of connection, in addition, the quantity of positioning groove can be set it is multiple, and adjust guide flat pipe upper limit protrusion position it is recessed Position in slot, thus it is possible to vary multi-angle integrated positioning is realized in the direction of guide pipe.

Preferably, the end of the guiding inclined tube, which is connected with, seamlessly transits the arc-shaped transition to alter course downwards for conducting wire Pipe.

On the one hand arc-shaped transition pipe can allow the conducting wire being pierced by from guiding inclined tube smoothly to alter course downwards, avoid and lead Long Term Contact leads to the generation of abrasion condition between line and guide pipe, and on the other hand, arc-shaped transition pipe can be effectively reduced or be avoided Rainwater is redirected back into parallel groove clamp from guiding inclined tube, to further mitigate rainwater to the adverse effect of conducting wire.

Preferably, the angle between the guide flat pipe and guiding inclined tube is 120 ° ~ 150 °.

Preferably 135 ° of angle be oriented between inclined tube and guide flat pipe, it is ensured that penetrating conducting wire in guide pipe can be from Guide flat pipe is smoothly pierced by with guiding inclined tube, is mitigated and is reduced the abrasion between conducting wire and guide pipe.

Further, the clamp is intracavitary is equipped with through fishbolt and two clamping plates hyperbola together in tandem Clamp body is provided with clamp slot at corresponding lead in clamp body.

Clamp slot screws in clamping process, clamp for placing conducting wire and by clamping plate to conductor clamping in parallel groove clamp Body can with original parallel groove clamp deform be in hyperbolia, clamp body deformation after can effectively, securely clamp conducting wire, to guarantee to connect It connects good.

Preferably, being equipped with copper or aluminum welding layer in the clamp slot.

The intermediate hyperbola clamp body connected is sandwiched by the intracavitary string of the clamp in parallel groove clamp, with electrical lead The same or similar copper of material, aluminium or copper-aluminium transition material etc. are special to be formed, and original parallel groove clamp contact resistance is effectively overcome Greatly, the shortcomings that linkage interface galvanic corrosion wound is fast, and power circuit burn line-outage contingency occurs.

The utility model has the beneficial effects that

One, locating sleeve and the guide pipe with locating sleeve cooperation are installed on clamping plate, so that conducting wire is being pierced by positioning sleeve The guide pipe being obliquely installed upwards is penetrated after pipe, is remained at such conducting wire and insulating layer downwards, be can avoid rainwater intrusion and is led The case where electricity box of the conducting wire other end are flow in line and along conducting wire generation, can prevent harm caused by the corrosion because of rainwater.

Two, it is connect by the way that locating sleeve is arranged with guide pipe, the time, which has been grown, to be unlikely to deform, and can be used for a long time and positioning sleeve Pipe is cooperated with guide pipe by limiting groove and positioning protrusion, and multi-angle combination is carried out, and cooperation conducting wire is facilitated to use.

Three, easy to operate, in-site installation personnel, which need not rely on technical requirements and working experience, can make the erector of specification Skill.

Four, by the way that clamp body is arranged in clamping plate, screwed in clamping process in parallel groove clamp, clamp body can with original and The deformation of ditch wire clamp is in hyperbolia, after the deformation of clamp body can effectively, securely clamp conducting wire, to guarantee that connection is good.
