Abstract
A kind of isolation handcart line arm connection structure, comprise insulating cylinder, be radially fixed on upper wire outlet seat and the lower wire outlet seat on this insulation barrel, and the connector that electrically connects two wire outlet seats, it is characterized in that: the connected body that described upper wire outlet seat or lower wire outlet seat stretch in a chamber is the plate that both sides are plane, and the plate of two wire outlet seats is spirally connected into galvanic circle by two copper bars as connector.The utility model is by changing upper and lower wire outlet seat structure, and replace original copper pipe as connector with copper bar, not only can omit lower carriage, save and make material, reduce production costs, and, omit after support, both shortened path, galvanic circle, reduced loop resistance, also removed wire outlet seat connected body has been stretched into placing restrictions on of a cavity length, the contact-making surface area of connected body is increased considerably.The ZN85-40.5/1600A all insulation formula of take isolation handcart is example, and through practical measurement, the contact-making surface area after improvement can increase by 2.5 times, has greatly promoted the galvanization ability of galvanic circle.
Description
Technical field
The utility model relates to a kind of isolation handcart line arm connection structure.
Background technology
Before the utility model is made, existing isolation handcart line arm connection structure, comprises insulating cylinder, upper lower carriage, upper and lower wire outlet seat and copper pipe.Two wire outlet seats are bolted on the upper-lower position of insulating cylinder, and wherein, upper bracket is radially placed in the cylinder chamber of contiguous upper wire outlet seat, and are connected on the connected body contact-making surface that upper wire outlet seat puts in a chamber in the mode of screw fastening; Copper pipe as connector is axially built in a chamber, and two ends are spirally connected fixing with upper and lower support respectively; Lower carriage is connected on the connected body contact-making surface that lower wire outlet seat stretches into a chamber in the mode of screw fastening equally, and so far, two wire outlet seats, two supports and copper pipe form a galvanic circle.This structure has its defect: two wire outlet seats need to be realized and connecting through upper and lower support and copper pipe, not only relates to that parts are many, waste of material is large, and, galvanic circle path length, contact-making surface is many, has increased galvanic circle resistance.Secondly, be subject to a chamber internal diameter and support to stop the impact of factor, the connected body length that two wire outlet seats stretch into a chamber is placed restrictions on, and causes contact-making surface area little, and through-current capability is poor, and easily heating and loss are large.
Summary of the invention
For addressing the above problem, the utility model aims to provide a kind of isolation handcart line arm connection structure, and this syndeton has the plurality of advantages such as the parts of relating to are few, loop resistance is little, through-current capability is strong.
For achieving the above object, the utility model has adopted following technical proposals:
A kind of isolation handcart line arm connection structure, comprise insulating cylinder, be radially fixed on upper wire outlet seat and the lower wire outlet seat on this insulation barrel, and the connector that electrically connects these two wire outlet seats, it is characterized in that: the connected body that described upper wire outlet seat or lower wire outlet seat stretch in a chamber is the plate that both sides are plane, and the plate of two wire outlet seats is spirally connected into galvanic circle by two copper bars as connector.
During concrete enforcement, the top of described connected body has two U-shaped grooves of receiving standing screw.
Beneficial effect, compared with prior art, the utility model is by changing upper and lower wire outlet seat structure, and replace original copper pipe as connector with copper bar, not only can omit lower carriage, save and make material, reduce production costs, and, omit after support, both shortened path, galvanic circle, reduced loop resistance, also removed wire outlet seat connected body has been stretched into placing restrictions on of a cavity length, the contact-making surface area of connected body is increased considerably.The ZN85-40.5/1600A all insulation formula of take isolation handcart is example, and through practical measurement, the contact-making surface area after improvement can increase by 2.5 times, has greatly promoted the galvanization ability of galvanic circle.
For deepening understanding of the present utility model, below in conjunction with accompanying drawing, by embodiment, be described in further detail.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.This isolation handcart line arm connection structure, mainly consists of insulating cylinder 1, upper wire outlet seat 3, lower wire outlet seat 4 and copper bar 5, the top of insulating cylinder 1 dust hood 2 of setting up defences.Upper wire outlet seat 3 is positioned at the upper end of insulating cylinder 1, through being bolted to, receives in contact arm chamber 6, forms integral body with the barrel of insulating cylinder 1.Screw 31 on upper wire outlet seat 3 right sides is for connecting upper contact arm (not shown), and the radially extended connected body 32 of upper wire outlet seat 3 left ends stretches into insulating cylinder 1 inner chamber.The length of connected body 32 is longer, electrically connects contact area just larger, and generally, its end face should extend near the shaft centre line of insulating cylinder 1.The shape of connected body 32 is roughly the plate that both sides are plane.For making copper bar 5 connect securely upper and lower wire outlet seat, the top of connected body 32 has two U-shaped grooves 33, to receive screw rod.During assembling, two copper bars 5 are placed on respectively the both sides of connected body 32, by the fastening realization of screw arbor assembly, are connected.The structure of lower wire outlet seat 4, installation method are consistent with upper wire outlet seat 3, are not repeated.
This syndeton is only the part that isolation handcart forms.During assembling, after upper and lower wire outlet seat and turnover contact arm are spirally connected, the Mume flower contact of the dependence turnover contact arm other end is realized and being connected with major loop, utilizes visible port, and realization disconnects, connection circuit object.
Above-described embodiment is intended to explain of the present utility model opening one's minds, and should not to be considered as be the restriction to its protection range.
Accompanying drawing explanation
Fig. 1 is the vertical profile structural representation of a related insulating cylinder of the utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Fig. 3 is the right TV structure schematic diagram of upper wire outlet seat 3 in Fig. 1.
Fig. 4 is the left TV structure schematic diagram of Fig. 3.
In figure: insulating cylinder 1, dust cover 2, upper wire outlet seat 3, screw 31, connected body 32, U-shaped groove 33, lower wire outlet seat 4, copper bar 5, receives contact arm chamber 6.
