Description
Technical field
The present invention relates to insulated connectors, a kind of insulation stripping in the insulated connectors specifically moves splicing ear.
Background technology
The insulation stripping moves connection (IDC), is a kind of electric connection mode of exempting to weld, and makes heart yearn be able to contact terminal the termination of line to be provided, promptly so-called wire holding clamp with electrical contact.One wire is pressed in the terminal groove of accurate control so that two side shifting wire insulation skins and make solid core or the distortion of multiply core in the groove.So-called terminal is that the insulation stripping moves one of them parts in the connection, is a kind of electric conductor, is used to contact other a kind of conductor (like electric wire) with the conducting electric current.Opening of terminal, the middle part fluting, the other end sealing forms Y-shaped or harpoon shape, and both sides produce two arm of forces, and the guiding slope is arranged near the notch.
The existing insulation stripping of existing terminal structure decision moves the mechanics feature of connection, and electric wire is in the process of pressing down, and the distortion of the groove root of terminal two arm of forces is increasing, and near the upper part of groove (notch) is more and more wideer, and the pressure that the electric wire both sides receive is increasing.Electric wire is in different depressed position, and suffered lateral pressure is different.The distortion of the root of terminal two arm of forces is big, and stress is big, and two arm of force upper parts of terminal outwards open, and is out of shape for a short time, and stress is little.There is following technical problem in such mechanics feature.
1, to be pressed into power big for electric wire, can't free-hand realization insulation stripping move connections (needing special-purpose instrument) because electric wire the oral area of groove need be certain lateral pressure, move the wire insulation skin otherwise can't shell.In a single day reach required stripping and move, electric wire just can't free-handly be pressed onto the required degree of depth.
2, the electric wire line that is connected is directly required height; The terminal that is the certain specification groove width can only connect very close limit, even wants single-minded line electric wire directly, because the distortion of terminal is confined to the root of the arm of force; Just the most of arm of force root that leans on of the amount of interference of electric wire and terminal groove absorbs; But excessive distortion can make the surrender of terminal root, even cracking, makes to connect and loses efficacy.
3, need strict control electric wire compression distance, because the different degree of depth that presses down, the lateral pressure of groove is different, and the deformation extent of electric wire is different, and the deformation extent of terminal is also different, and the effect of connection is also different.
4, the current capacity of electric current is less, because the groove side is the plane, core is the face of cylinder, and contact area is less.
5, the electric wire core is weighed wounded easily, because electric wire is pressed in the process, pressure at both sides constantly increases, and bad control is prone to weigh wounded core.
6, connect less stable.After electric wire was pressed into terminal, the terminal groove oral area that becomes was wide, and root is narrow, and electric wire is extruded, the trend of " being spued ".If what outer bound pair electric wire produces and disturb, electric wire comes off from terminal easily, makes to connect to lose efficacy.
Summary of the invention
Technical problem to be solved: the object of the invention provide a kind of can adapt to the plurality of specifications lead, that push lead easily and link insulation stripping closely move splicing ear.
Technical scheme: a kind of insulation stripping moves splicing ear, comprises the splicing ear main body, in the middle of said splicing ear main body, establishes a central channel, extends a wire jack on central channel top, establishes the first side force arm hole in central channel one side.
Be provided with breach at said central channel side.
Establish the second side force arm hole at said central channel opposite side.
Said breach is located at the middle part or the bottom of central channel side; Said breach is circular-arc, ellipticity, V-type or polygon-shaped.
Said wire jack is a circular hole, square hole, tri-angle-holed, rectangular opening or polygonal hole, or above combination of shapes hole.
Said wire jack open upper end, the position button of limiting in open upper end two outsides.
The said first side force arm hole is a strip.
The said first side force arm hole is one or more holes combinations in circular hole, square hole, elliptical aperture, the tri-angle-holed or polygonal hole.
The said second side force arm hole is a strip.
The said second side force arm hole is one or more holes combinations in circular hole, square hole, elliptical aperture, the tri-angle-holed or polygonal hole.
Outstanding feature of the present invention and remarkable result are following.
Splicing ear closed at both ends of the present invention, arm of force perforate forms support arm and distortion arm respectively; Breach is established in the central channel side, increases the contact-making surface with lead.
The present invention produces following mechanics feature: electric wire is in the process of pressing down, and terminal no longer occurs one and opens, and the other end less changes, but almost whole terminal can produce distortion comparatively uniformly, and the distribution of stress also is greatly improved.The distortion of the arm of force no longer concentrates on root, and whole distortion arm stress is very even, and distortion is very coordinated, and electric wire lateral pressure in the process of pressing down is no longer increasing like this.Simulation of utilization FInite Element or emulation electric wire are pressed into the situation of splicing ear, confirm that above analysis is rational.
Such mechanics feature improves the technical problem of original terminal greatly.
1, reduces electric wire and be pressed into power, can realize that free-hand insulation stripping moves connection, does not need special-purpose instrument.Because it is big more that the power that is pressed into of electric wire is pressed no longer more.
2, the electric wire line that is connected is directly required to reduce; The terminal (groove width) that is certain specification can connect the more electric wire in wide region line footpath; Because no longer being confined to the root of the arm of force, the distortion of terminal is distributed in whole terminal; Just the amount of interference of electric wire and terminal central channel no longer mainly leans on arm of force root to absorb, but whole terminal.
3, do not need strict control electric wire compression distance, because the different degree of depth that presses down, the lateral pressure of central channel is much the same, and the deformation extent of electric wire is also much the same, and the deformation extent of terminal does not have much variations yet, and the effect of connection there is not difference.The contact-making surface of the inboard breach of groove is the face of cylinder in addition, and core also is the face of cylinder, makes electric wire that a kind of trend of making compression distance by oneself arranged in the process of pressing down.
4, the current capacity of electric current is bigger, because the concane gap contact-making surface is the face of cylinder in the groove side, core is the face of cylinder, and contact area increases.
5, the electric wire core is not easy to be weighed wounded, because electric wire is pressed in the process, pressure at both sides changes little, and therefore core can not weighed wounded.
6, connection is stable; After electric wire was pressed into terminal, central channel no longer oral area was wide, and root is narrow; But narrow centre, two is wide; Electric wire has the trend in the middle of being trapped in, and the contact-making surface of concane gap further makes electric wire held more jail in the groove side in addition, is difficult for losing efficacy because of outer bound pair electric wire generation interference makes electric wire come off to cause connecting from terminal easily.
