Abstract
The utility model discloses a mechanical locking T-shaped connector, comprising a connecting pipe seat at least having three conducting wire connectors, particularly a T-shaped connecting pipe seat, wherein, a conical conducting wire locking devices are arranged in at least one conducting wire connector. The connector having a plurality of end heads has the advantages of convenient construction, safe and quick operation, time saving, labor saving and high work efficiency. In addition, the contact area of a conducting wire connecting part is large, pressure is uniform, DC resistance is small, temperature rise loss is low, and the utility model is suitable for the connection of lower guiding wires in bare conducting wires and cables having larger cross sections and the connection of the branch service entrance wires of a main insulating wire.
Description
The utility model belongs to a kind of new mechanical cone locking jockey, and it is applicable to that plain conductor is connected with the T shape of steel core plain conductor and tape insulation cable.
At present the downlead T shape of various device connects and all adopts screw bolt-type and the crimp type mode realizes in the electrical network, and its standard is level decades ago.Two kinds of modes all exist in the construction and waste time and energy, and work efficiency is low, operating difficulties, and contact pressure is inconsistent, drawbacks such as assembly quality instability cause that thus the joint over-heated fault happens occasionally, and are the weak links in the electric power netting safe running.
In low voltage power distribution network, from the backbone to user, connect the family downlead, because of its changes of section scope is big, be to adopt colligation mode, the 2nd, the general C shape of the peace of just promoting the use of recently wire clamp with T-branch ways of connecting one on the backbone.The former, construction is inconvenient, and joint quality is bad, and the latter is too many because of the various cross sections combination of backbone and service conductor, can't satisfy the needs of various operating modes, and its price is also quite expensive.
The purpose of this utility model is to provide a kind of mechanical interlocking T shape connector, to overcome above-mentioned deficiency.
For realizing the purpose of this utility model, the inventor proposes following technical scheme by many kinds of contrived experiments: it comprises the connection base, connects base and has three lead connectors at least, has at least to be provided with lead taper circle locking device in the lead connector.The conical locking device of lead comprises the special-shaped lock nut that is connected with lead connector hole, the split-type cone locking sheet by special-shaped lock nut location that is provided with in the hole.
Compare with original mechanical connection manner, the utlity model has tangible technological merit: the one, by inserting, the spinning locking mode is finished the connection of joint, and easy construction is simple to operate, and is time saving and energy saving, the operating efficiency height.The 2nd, the lead contact area is big, and pressure uniform DC resistance is little, loss, and temperature rise is low, simultaneously, adjusts nargin and has overcome the inconsistent drawback of contact pressure that differs and produce because of diameter of wire greatly.The 3rd, simple in structure, good manufacturability reliability height.The 4th, its guide flow path is reasonable, and the 5th, connection is reliable, tensile strength is big, enough bears the pulling force on the lead.When realizing that better connector uses, the lead retaining part is stressed little, and water conservancy diversion is good: the bearing position heating is few
The "T"-shaped connector structure chart of Fig. 1 conical locking lead.
Fig. 2 C shape base T shape connector structure chart.
Embodiment 1
As shown in Figure 1, the connection base 3 of connector is three lead connectors of "T"-shaped layout, establish the conical locking device of lead in each connector, each the lead connector end that is specially tube connector is connected with special-shaped lock nut 1, connects to establish the conical stay 2 of split-type in the base.The conical stay 2 of split-type is two sections; One section is distinguish conical sleeve 21, and another section is for being inserted in the abutment sleeve 22 in the special-shaped lock nut.It is corresponding with lead radial section shape to cross sectional shape that the distinguish open slot 23 of the conical lock of split-type eyeball leading portion extends to abutment sleeve 22 upper conical stay 2 internal orifice dimensions, as be circular, fan-shaped or other odd shaped hole (not shown), conical stay 2 bore wall of split-type are carved with anti-skidding groove 24.Chamfering 12 is offered in abnormity lock nut endoporus 11 outer ends, and the shaft shoulder 13 is established in special-shaped lock nut the inner, and the shaft shoulder 13 end faces contact with the large end face of the distinguish conical sleeve 21 of the conical stay of split-type.
As shown in Figure 2: the connection base 3 of connector is "T"-shaped layout, establishes the conical locking device of lead in the connector, and the conical locking device of lead is identical with the conical locking device of above-mentioned lead.Connect base two connectors formation " C " shape opening Connection Cards 4 in addition, " C " shape opening Connection Card 4 is divided into lead clamping screw 5, establishes lead clamp 6 on the lead clamping screw 5.
Use the T shape connector of embodiment 1 right, at first horizontal main line is passed the horizontal tube middle punch that T shape connects base, behind the location, tighten the two ends lock nut with permanent square instrument and get final product.The lower end centre bore locking of its downlead insertion T shape connection base.
When using the upper end of embodiment 2 to connect as C shape opening T shape, earlier peeling insulated conductor section is put into C shape upper end circular arc from opening part, level is put into clamp, clamp bottom surface location hole is aimed at the pushing tow bolt, in the bottom nozzle centre bore, tighten the pushing tow bolt, the horizontal backbone of connection with permanent square instrument.
Its locking principle is:
Embodiment 1:
Horizontal base is a penetration type in the T shape connection base T shape connector, the main line of bare conductor cable passes base from centre bore, and two ends abnormity nut is rotated with permanent square instrument, and the conical stay of compressing distinguish is along translation on the base inner conical surface, and shrink generation one thrust entad gradually, lead is locked.This moment, lead penetrated cone locking sheet endoporus naked section, by current flowing path greater than tens of times of sectional area of wire of inner conical surface formation of conical stay outer surface and base.Simultaneously, the characteristics adjusted and the nut of taper lock body leading apply constant-torque, can guarantee the reaching unanimity property of contact pressure on this area.Its downlead end base structure and locking method are same as described above.
Embodiment 2:
In the upper end open C shape base T shape connector, C shape upper end open place can put into insulation trunk lead skinner then level put into clamp, clamp bottom surface awl circular hole is aimed at the pushing tow bolt, lower end endoporus from C shape base, tighten the pushing tow bolt with permanent square instrument, be about to the locking of level insulation backbone.It is same as described above to connect main line base structure and locking method under it draws.
