Abstract
The utility model provides a switch-mode bridging piece, which comprises a plastic shell and bridging metal pieces wrapped by the plastic shell. The upper end of the plastic shell is provided with at least one set of plastic push-pull structural pieces, wherein current bars are wrapped inside the plastic push-pull structural pieces. A plurality of sets of bridging metal pieces are arranged side by side, and the lower ends of the bridging metal pieces are blade-shaped. The switch-mode bridging piece is characterized in that the current bars are elastic components with openings. The installation of the push-pull structural pieces is realized in an elastically pressing-in and pressing-out manner. The bridging metal pieces are machined through the bending process. The upper ends of the bridging metal piece are provided with dead bolt type end heads, and the middle parts of the bridging metal piece are elastic. The two sides of the bridging metal pieces are narrow. The bridging metal pieces and the push-pull structural pieces are fixedly connected in a screw-free buckling manner. Then the metal bars are pushed along push-pull grooves into dead bolts at the upper ends of the bridging metal pieces to be mutually and fittingly locked with the push-pull structural pieces. Therefore, the on-site installation efficiency is improved.
Description
Technical field

Background technology
In electric power system, use pluggable disjunction calibrating terminal that the instrument and meter in system is measured or overhauled, can search problem a little fast, and resume production, this is quite general in electric power system, so all require higher to its ease for use and economy; If adopt welding manner to connect, be danger close, cold and hot contraction, long-time rear pad is just likely de-, adopts bridgeware cost lower; Simple to operate, easy to use.
At present, the disjunction calibrating terminal of existing various ways and bridgeware exist, the cross section scope that the most frequently used universal large electric current disjunction calibrating terminal can connect wire is 16-240mm2, has taked two groups of plug bridge joint metalworks to guarantee reliable wiring on general terminal construction; Terminal central authorities are used Fast Labeling bar to identify, large and clear, are also easy to debate knowledge even if connect line; Through type terminals subband two is arranged bridgeware, can realize fast and neatly current potential and distribute; Pulling-back type spring connected mode combination binding post, because guaranteed maximum wiring space, can be realized the fast-wiring of multicore cable and solid conductor, meanwhile, also can be used for adding the wire of pre insulated tubulose termination.
But also there are some shortcomings and shortcoming to exist, as Fig. 1, shown in Fig. 2, the isolating terminal that a kind of screw connects, it utilizes screw self-locking to fix, after the metallic conductor that this class terminal is made of plastics the insulation shell parcel of bipartite slip superposes up and down, hold-down screw connects, then trip bolt, with its side by side moulding also have the some groups of buckles with back-off that are made of plastics, lower end is except one group of intrinsic plug bridge joint metalwork, also has the plastic buckle of one group of location plug assembly, this makes installation procedure more negative assorted, cost and Master Cost increase, be unfavorable for batch production and large-scale application.
Therefore,, in order better to address the above problem, adopt the final purpose that following technical proposals is this paper.
Summary of the invention
In order to overcome the deficiencies in the prior art, the connected mode that proposition is electrically connected isolating terminal on switch is connected and is changed to elastic wall connected mode by screw, boosting handle is more easy to operate, remove location plug assembly working of plastics, the on-the-spot shell foot that employing is installed is pressed into the mode of extrusion, and economy and field erected convenience significantly improve.
The object of the technical program, will be achieved by the following technical programs:
Along with client's demand diversity all the more, we not only will realize quick bridge joint terminal, for client considers the saving of space and cost, and on original product basis, existing product mounting means are improved to some extent.Switching regulator bridgeware, the bridge joint metalwork that comprises a plastic casing and wrapped up by plastic casing, plastic casing upper end, place also comprises the plastic sliding structural member of at least one group of parcel current bar, some groups of described bridge joint metalworks are arranged side by side, and lower end is tooth shape, it is characterized in that: described current bar is the elastic component of opening, the elasticity that the installation of push-pull configuration part adopts is pressed into the mode of extrusion, described bridge joint metalwork adopts bending technique to complete, dead bolt shape termination, upper end mid portion has elasticity and both sides are narrow, fixing employing screwless buckle mode between described bridge joint metalwork and push-pull configuration part is connected, and along push/pull slot, current bar is pushed in the dead bolt of bridge joint metalwork upper end, with the locking that cooperatively interacts of push-pull configuration part, improve on-the-spot installation effectiveness.
The application of the technical program structure, its outstanding effect shows as:
1, compared with former technical scheme before improving, the bridge joint metalwork of this programme is reduced to a slice by two, and economy significantly improves, and the mode being connected by traditional screw changes the mode of crimping into, and efficiency and economy promote greatly;
2, external shell adopts industrial flame retardant grade insulating material, because this type of material has various shapes, shock-resistant, simultaneously again in this product use procedure and have the electric property of safe insulation between circuit, not only attractive in appearance but also safe and reliable;
3,, compared with existing product, due to the plastic buckle of one group of location plug assembly of case material structure decrease, save the cost of installing space and material;
Below in conjunction with embodiment accompanying drawing, the embodiment of this practical plan is done further to decompose, so that the technical program is easier to understand, grasp.
