Description
Technical field
The utility model relates to technical field of electricity, specifically a kind of binding post.
Background technology
China is large agricultural country, every agricultural irrigation peak season, and the motor-pumped well in field is concentrated and is used, and an agriculture row transformer often will supply 3 ~ 6 motor-pumped well electricity consumptions, and in motor-pumped well, the power line of all motors is often connected on the same disconnecting link binding post of slate switch simultaneously.Owing to connecting multiple conducting wires on disconnecting link binding post simultaneously, the bolts and nuts that easily occur compression wire cannot be fixed or fixing unstable situation, especially in the time that many motor-pumped wells are worked simultaneously, between wire and bolt, contact area is little, contact resistance is large, easily heating or because overcurrent catches fire, thus burn out disconnecting link, even burn out water pump.In addition, because multiple conducting wires is crimped between one group of bolts and nuts simultaneously, therefore, in the time that a certain motor-pumped well needs repairing, many wires that are connected on same disconnecting link need to be removed simultaneously, cause many motor-pumped wells to quit work, and have a strong impact on normal agricultural production.As other motor-pumped wells need to work on, need the wire of maintenance to find out, then other wires are connected on binding post simultaneously, operating process is comparatively loaded down with trivial details.
Utility model content
The purpose of this utility model is to provide a kind of porous binding post that can simultaneously connect multiple conducting wires on disconnecting link that is arranged on, and is directly connected to the problem of power supply instability on the binding post of same disconnecting link to solve multiple conducting wires.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Be applied to the porous binding post of disconnecting link, comprise the copper terminal block of bar shaped and the protective cover being equipped with mutually with terminal block, one end of terminal block is provided with stretches out the projection that protective cover is connected with disconnecting link binding post, on the protective cover sidewall of the terminal block other end, is provided with arc line outlet; On described terminal block, be set side by side with several bolts hole, each bolt hole is all equipped a set of for compressing the bolts and nuts of wire, and the head of described bolt is positioned at the cavity of terminal block and protective cover formation, and nut is positioned at the below of terminal block.
Further improvement of the utility model is: between the head of described bolt and terminal block, be also provided with the pressure-ray film for compressing wire.
Further improvement of the utility model is: described pressure-ray film middle part is provided with for the through hole through bolt, and the edge of pressure-ray film is the U-shaped structure towards terminal block.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model can directly be connected with disconnecting link and be connected with multiple conducting wires simultaneously safety and firmness, and easy installation and removal, can increase and decrease user at any time.
Multiple bolts hole are set on described terminal block, guarantee that every wire has own independent binding post, can control separately a certain motor-pumped well work.
The edge of described pressure-ray film is the U-shaped structure towards terminal block, makes wire to be drawn in around bolt in compressing wire, has increased the contact area of wire and bolt, has avoided occurring because of heating, electric discharge phenomena that loose contact causes.
Described terminal block periphery is provided with transparent insulation protective cover, prevents rain drop erosion terminal block, avoids the foreign matters such as dust to enter, thereby greatly reduces phase fault and electric arc odds.

Wherein, 1, terminal block, 2, pressure-ray film, 3, bolt, 4, bolt hole, 5, protective cover, 6, arc line outlet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Be applied to the porous binding post of disconnecting link, its structure as shown in Figure 1, comprises terminal block 1, pressure-ray film 2 and protective cover 5.
The material of terminal block 1 is copper, and its structure is bar shaped, is set up in parallel the bolt hole 4 that several and bolt 3 match on terminal block, and the front end of terminal block 1 is provided with projection, is also provided with bolt hole 4 on projection, for being connected with the terminal of disconnecting link wiring.Each bolt hole 4 on bar shaped terminal block 1 is equipped a set of bolt 3 and nut all, for being wound around and compressing wire.The head of bolt 3 is positioned at the top of terminal block 1, and nut is positioned at the below of terminal block 1.
Pressure-ray film 2 is between the head and terminal block 1 of bolt 3, the middle part of pressure-ray film 2 is provided with through hole, be used for through bolt 3, the edge of pressure-ray film 2 is set to the U-shaped structure towards terminal block 1, make pressure-ray film 2 wire being wrapped on bolt 3 can be compressed and draw in the inner side, edge at pressure-ray film 2, increase the contact area of wire and bolt 3, avoided causing because of loose contact the generation of heating, electric discharge phenomena.
The protective cover 5 that adopts transparent insulation material to make is rectangular-shaped, and the bottom of protective cover 5 is provided with opening, is provided with the arc line outlet for drawing wire on the rear end face of protective cover.Protective cover 5 is fastened on the periphery of terminal block 1, can facilitate maintainer to be well understood to wiring situation, can prevent that again rainwater from directly washing away terminal block 1, stops the foreign matters such as dust to enter, and effectively avoids the generation of phase fault and electric arc.
While using the utility model, first terminal block 1 is directly connected on disconnecting link binding post, uses bolt 3 to coordinate with nut fastening, guaranteed main line contact firmly; Secondly, bolt 3 is passed to the bolt hole 4 on through hole, the terminal block 1 at pressure-ray film 2 middle parts successively, wire is wrapped on the bolt 3 between pressure-ray film 2 and terminal block 1, and after bolts and nuts cooperation is tightened, pressure-ray film 2 can compress wire draw in the inner side, U-shaped edge at pressure-ray film 2; Finally, protective cover 5 is fastened on to the periphery of terminal block 1, wire is drawn and can be completed connection from the arc line outlet 6 of protective cover 5.In the time of a certain motor-pumped well maintenance, only need breakdown protective cover 5, the circuit that dismounting is connected with this motor-pumped well, can not affect other motor-pumped wells and normally work.
Terminal block 1 of the present utility model can also be arranged to tubulose or other shapes as required.
