Description

Electric wire connecting junction

Technical field

The utility model belongs to the interconnection technique field of conductivity.

Background technology

In the prior art, electric wire connecting junction comprises pedestal, is provided with copper sheathing on pedestal, and the copper sheathing side is provided with screw hole, is provided with screw in the screw hole.During use, plural line is penetrated in the copper sheathing, tighten screw, so just can be with the lead fixed in the copper sheathing, and realize the connection of electricity.The problem that this electric wire connecting junction structure exists is that the connection of lead tightens up by the screw rotation on the one hand, in case screw is lax, then can cause loose contact, and the contact resistance of contact site is increased, and causes heating burnout.Each on the other hand wiring all needs to twist screw, wiring inconvenience.The 3rd screw, Screw hole structure complexity are not easy to make.The 4th screw exposes, and causes easily getting an electric shock.

The utility model content

The purpose of this utility model is to overcome the shortcoming of the existence of prior art, provide a kind of patch quick, electrically contact reliable, simple in structure, be convenient to make, be difficult for the electric wire connecting junction of contact electric conductor.

For realizing the purpose of this utility model, described electric wire connecting junction, comprise housing, plug wire hole, in described housing, be provided with conducting strip, described plug wire hole has two and sensible to conducting strip at least, interior corresponding at least two shell fragments that suppress on conducting strip that are provided with of described housing, and the angle between the corresponding plug wire hole with it of described shell fragment is less than 90 degree.

Because conducting strip and shell fragment are provided with in the housing, the user can't touch these electric conductors, therefore is difficult for causing getting an electric shock.Angle between shell fragment and the plug wire hole is less than 90 degree, when electric wire will withstand on the shell fragment after plug wire hole inserts, shell fragment is opened, when electric wire inserts through behind the end of shell fragment, shell fragment suppresses electric wire on conducting strip, electric wire was hooked and can't outwards pull out by shell fragment this moment, therefore patched quick, reliable.Twist together because electric wire is a multiply, shell fragment keeps suppressing on strand wire, even electric wire produces lax distortion, shell fragment still can carry out good electrical contact with it.This connector relates generally to shell fragment, conducting strip and housing, and shell fragment, conducting strip, hardware wherein can be by punch forming make to sheet metal, and plastic casing is by the injection moulding one-shot forming, and the technology manufacturing is simple, is convenient to make.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model electric wire connecting junction is described in further detail:

Embodiment 1, as Fig. 1,2,3,4, shown in 5, electric wire connecting junction described in the utility model, comprise the housing 1 that plastics are made, on housing 1, can be arranged to rare two plug wire holes 2 as required, present embodiment is provided with three circular plug wire holes 2, in housing 1, be provided with the square conducting strip 3 that the copper sheet punching press is made, plug wire hole 2 is sensible to conducting strip 3, housing 1 interior corresponding at least two shell fragments 4 that suppress on conducting strip 3 that are provided with, shell fragment 4 has three in the present embodiment, and shell fragment 4 is made by the rubber-like steel disc, and the angle between the corresponding plug wire hole 2 with it of shell fragment 4 is less than 90 degree.

Because the space in the housing 1 is very little, for the elastic force that increases sheet shell fragment too be convenient in housing fixingly, shell fragment 4 afterbodys are provided with

support arm

5,5 one-tenth hook solid of shell fragment 4 and support arm, and support arm 5 is attached on the housing 1 inner chamber wall.Shell fragment support arm 5 when bending can be done suitable distortion thereupon, to strengthen elasticity.Support arm 5 abuts on the housing 1 inner chamber wall in addition, makes the root of shell fragment 4 that the good supporting position be arranged, and assembly structure is simple, and is fixing reliable.

Shell fragment 4 is connected the bending place and is provided with the Baltimore groove 6 of bending thereupon with support arm 5.Baltimore groove 6 can make the elastic force between shell fragment 4 and the support arm 5 increase, and makes the sheet metal of shell fragment 4 and support arm 5 like this and can select relative thin sheet metal, can save material, make easily again, and the elasticity of shell fragment 4 is big.

Support arm 5 is provided with on the public brace 7, and all support arms 5 are structure as a whole with brace 7.Therefore shell fragment 4, support arm 5, brace 7 can conveniently be made by the firm sheet punch forming of a slice rubber-like.Because all shell fragments 4 form an overall structure by support arm 5 and brace 7, in housing 1 inner chamber relatively large Area of bearing are arranged, need not just can make it fixing firm by other securing members.

Housing 1 is provided with the seat of honour 11 and end cover 12, and plug wire hole 2 is arranged on the seat of honour 11.End cover 12 is provided with first location notch 8, and the tail end of brace 7 is arranged in first location notch 8.During assembling, can earlier shell fragment 4, support arm 5 and brace 7 be installed in the seat of honour 11, when the seat of honour 11 and end cover 12 lumps together, the tail end of brace 7 then is entrapped in first location notch 8 of end cover 12, all shell fragments 4 are fixed, parts simple in structure, assembling is easily.

Housing 1 is provided with the seat of honour 11 and end cover 12, and end cover 12 is provided with second location notch 9, and the seat of honour 11 is provided with the 3rd location notch 10, and conducting strip is arranged in second location notch 9 and the 3rd location notch 10 at two ends about in the of 3.When the seat of honour 11 and end cover 12 lumped together, the head of conducting strip 3, tail end then were entrapped in respectively in the 3rd location notch 10 and second location notch 9 and are fixed, parts simple in structure, and it is easy to assemble.

Embodiment 2, and described electric wire connecting junction is that with the difference of embodiment 1 wall that conducting strip 3 is provided with notch 13 notches 13 corresponding shell 1 is provided with through hole 14 as shown in Fig. 6,7,8,9,10.In the time the electric wire 20 that inserts need being released, only need to insert through hole 14, and push shrapnel 4 through notch 13 with a bar, it is separated with electric wire 20, just electric wire 20 can be extracted from plug wire hole 2.

Through hole 14 is provided with the button 16 that can withstand on shell fragment 4 ends, and button 16 is provided with the block 17 that is on housing 1 internal chamber wall.Button 16 keeps the situation of outwards upspringing under the elastic force effect of shell fragment 4, because the effect of block 17 and can not ejecting from through hole 14.When moving back electric wire 20, can pass through pressing keys 16, shell fragment 4 jack-up are left electric wire, so both safety was operated simple again.

Housing 1 is provided with the seat of honour 11 and end cover 12, and plug wire hole 2 is arranged on the seat of honour 11.The seat of honour 11 is provided with groove 15, and when the seat of honour 11 and end cover 12 lumped together, groove 15 constituted through hole 14 with the limit of end cover 12.When housing 1 adopts the seat of honour 11 and the end to cover 12 structures, can cover 12 injection mouldings to the seat of honour 11 and the end respectively, be convenient to the demoulding when injection mo(u)lding, easy to manufacture, assembling easily.
