Abstract

Provided is a movable spacer which is convenient and safe in use and is used for wiring pile heads of contactors. The movable spacer comprises a base plate and multiple sets of spacing mechanisms. The spacing mechanisms are arranged on the base plate. The base plate comprises multiple through holes, and T-shaped grooves are arranged among the through holes. The T-shaped grooves run through the base plate longitudinally. Each set of spacing mechanisms comprises support rods, double folding rods, single folding rods, first pivot pins, and second pivot pins connected between the double folding rods and the single folding rods. The double folding rods are movably connected with the two sides of one ends of the support rods though the first pivot pins. Each support rod comprises a support pin hole and a support hole used for fixing the top end of one single folding rod. Each double folding rod comprises a pair of first folding rods and a first cylindrical slide rod. The pair of first folding rods are arranged on the first cylindrical slide rod symmetrically. Each pair of first folding rods is provided with a connecting hole and a first rotating hole. The movable spacer reduces the probability of line short, and is convenient and safe in use.

Description

Movable escapement

Technical field

The utility model relates to field of power, relates in particular to the device of contactor wiring pile crown personal distance.

Background technology

Development along with Rural Social Economy, power load continues soaring, transform successively low-voltage platform area, rural area, backbone is generally replaced by LGJ-120 or JKLGYJ-185 and above insulated conductor by LGJ-35, the corresponding increase of rural comprehensive distribution box low pressure line cable, under causing cable connecting terminal that outlet cable uses and exchanging tentaculum, pile crown does not match, in running, usually touch phase phenomenon, cause low-voltage platform area Frequent trip, cause power supply quality to be complained and rise, both rural power grids equipment was brought to hidden danger, have a strong impact on again external service image.

According to actual state, analysis is touched phase fault and is usually come from A.C. contactor loosened screw, make the mandatory outlet cable installing originally be subjected to displacement and drive cable connecting terminal to take screw as initial point, to be not more than the angle rotation (as shown in figure 11) of 15 degree, thereby make directly contact generation short circuit between cable connecting terminal.

Utility model content

The utility model, for above problem, provides a kind of easy to use, safe, can be used for the movable escapement of contactor wiring pile crown.

The technical solution of the utility model is: draw together base plate and some groups of space mechanisms, described space mechanism is located on described base plate;

Described base plate comprises some perforatings, between adjacent described perforating, is provided with T-shaped groove, and described T-shaped groove longitudinally runs through base plate;

Described in every group, space mechanism comprises support bar, twofold bar, single lap bar, pivot pin one and is connected the pivot pin two of described twofold bar and described single lap bar, and described twofold bar is movably connected in the both sides of described support bar one end by described pivot pin one;

Described support bar comprises and supports pin-and-hole and for the supported hole of fixing described single lap masthead portion termination;

Described twofold bar comprises a pair of folding rod one and cylindrical sliding bar one, described a pair of folding rod one is symmetrically set on described sliding bar one, on described a pair of folding rod one, be equipped with connecting hole and rotating hole one, described connecting hole is movably connected in described support pin-and-hole by described pivot pin one;

Described single lap bar comprises folding rod two and cylindrical sliding bar two, and one end of described folding rod two is located on described sliding bar two, and described folding rod two is provided with rotating hole two, by described pivot pin two, is connected with described rotating hole one;

Described sliding bar one and two activities of described sliding bar are located in described T-shaped groove.

Spacing between adjacent described perforating equates.

Also comprise the stop plug supporting with described T-shaped groove, described stop plug is located at described T-shaped groove two ends.

The utility model utilizes space mechanism that the wiring pile crown of contactor is effectively separated to (as shown in figure 10), even if wiring pile head rotates, due to the existence of space mechanism, also can not occur to be in contact with one another because of wiring pile crown the phenomenon that is short-circuited.The utility model can freely be set level and erect simultaneously, realize movable function, while needing to use, pull-up support bar, sliding bar one on twofold bar and the sliding bar two on single lap bar slide in T-shaped groove, while moving certain position to, single lap masthead portion termination is put into the supported hole of support bar, realized support, balance; While not needing to use, be pulled upwardly support bar, supported hole pulled out in the termination, top of single lap bar, then along T-shaped groove, escapement is set level.The utility model effectively reduces the probability of line short, and easy to use, safe.
