Abstract

Without scolder and screw, the wire connection device that need not to divest insulation is specially adapted to the not aluminum steel and the multiply copper conductor in collinear footpath.The present invention is-the cross section whole connector of X-type, has two elastic deflectable right-angled parts across fixed central piece, has the support separately of corner-shape component, they and the corresponding engagement of two supports of the member at approximate S-type center; The cutting edge of stretching corner-shape component also limits receiving slit; In addition, the corner-shape component support partly can move towards edge direction, and corresponding support and another corner-shape component support limit centering partly of two V-types; In the V-type partly lower end that centers, both correspondingly are offset and lean against to have disposed privately and cut fork, and here, under without any the cut channel damage, cutting edge is as the face formula contact of selectable stranded conductor.

Description

Without scolder and screw and need not to divest the jockey of wire insulation

What this invention was related is a kind of the sort of device that is undertaken by this patent requirement 1 preamble.

A kind of without scolder and screw, the interconnection technique that need not to divest the conductor jointer of insulation has been developed application, this method of attachment is that people know already, promptly is known as the LSA-PLUS interconnection technique in this technical field.

In this LSA-PLUS interconnection technique, adopted vertical wiring (contact) device a kind of thin spring leaf system, that lean on wire clamp to clamp, it has the cannelure of an open type between two crossed strip lugs, the width of this groove is slightly less than the diameter (or size) of lead.

When lead was pressed into, the spring lug was because distortion correspondingly is offset, and like this, above-mentioned qualification contacts the corresponding cutting edge stripping of insulatin at the very start of the spring lug of groove, and predetermined amounts is filled into electric conducting material to form the contact of conduction then.

This operation can produce a kind of very firm, nonvolatil etch-proof electrical connection, and does not need to give in advance the electric wire peeling, does not also need to be connected with scolder with screw.

Above pointed the sort of connector (at DE-PS2, in 610,461

( )/()

※ LSA-PLUS(Iimited SPace-Charge accumulation-precision loa-ding and utilization System): LSA limited space-charge accumulation-precision apparatus with utilize system.

Set forth) exist certain shortcoming, that is, not that each lead can both connect.

For example, aluminum steel, multiply copper conductor (twisted wire) just can not connect with this connector, because might produce the danger of excessive notch effect.

So, the present invention is on the basis of above-mentioned the sort of device, improve, it also can all be suitable for aluminum steel and multiply copper conductor, without any infringement some is cut off or single cord by the situation of otch under, also can contact well, can directly regulate according to different lines simultaneously.And this novel connection is fit to insert the LSA wiring wire clamp that always uses at present.

Advantageously: insertion of up to the present having used or the instrument that takes out lead also can use (referring to DE-PS2,725,551, DE-GM8,013,494, DE-PS3,207,186) together with this new device.

Above-mentioned illustrative purposes according to the invention is to be explained by the feature of claim 1.

Use connector construction according to the invention, the air gap of its contact groove (for example can automatically be regulated, when conductor material is aging, can be in without any single cord otch that damages or stranded conductor under some quilt situation of cutting off, sub-thread or stranded conductor guarantee to have enough contact pressures on the composition surface of limit mouth all the time.

The advantage of various improvement means of the present invention is seen following claim.

With reference to the accompanying drawing of back, at length explain the present invention.

Fig. 1: the top view that is explanation X-shaped connector according to the invention;

Fig. 2: the profile that is Figure 1A-A;

Fig. 3: be the profile of Figure 1A-A, a lead is arranged on the contact position;

Fig. 3 a: be the end view of contact part lead in Fig. 3, the insulation of lead strip off, connector does not here draw;

Fig. 4: be to have the further concrete manifestation of the connector of part in addition of two hook-types;

Fig. 5 is the top view of Fig. 4.

Fig. 1 has showed that connection lead 2(is particularly suitable for aluminum steel and multiply copper cash) whole connector, it has the cross section of X-shaped.

Because this structure just may obtain firm performance highly with thin material fully.

The insertion opening 3 of two V-arrangements and 4 is made of the X section bar.

Among Fig. 1, two the deflectable right angle of elasticity members 14 and 15 are meshed with fixing central block 18.

Angular member 14 and 15 pairing supports 16 and 17 engage with the support 19 and 20 of the central block 18 of approximate S shape. Angular member 14 and 15 cutting edge 10a and 10b are straightened and limit dump tank 10.

The support 16 of angular member and 17 parts can move towards cutting edge 10a and 10b direction, and corresponding support 16 limits two V- arrangement centering parts 5 and 6 with the support 17 of another angular member.

With to insert opening 3 the same, opening 4 is inserted at the rear portion of having drawn in Fig. 2, cuts fork 7 and 8(and centers partly that 6 bottoms form one for lead 2 concentrated areas being imported two), this insertion opening 4 has two V- arrangements part 5 and 6 of feeling relieved.

Can clearly be seen that from Fig. 1 cutting fork 7 and 8 has a skew accordingly, so that by the position insulation of scratching lead of skew.

In addition, cut fork 7 and 8 for two and limit a wedge mouth 11 each other, so that make incision operation more easy.Fig. 3 illustrates the lead that is inserted into: if when connecting the multiply copper conductor, under otch or one cut-out situation without any infringement lead 2, the core that stretching side 10a and 10b oppresss lead 2 with doing one's utmost also generation contacts with a kind of formula of lead 2.Here, the recuperability of LSA-PLUS and torsion are quite tangible.

The width of groove and flexible angular member 14 and 15 have been determined contact pressure: if the wire diameter that uses is bigger, then contact pressure is also just big.

In addition, as can be seen from Figure 3: along with the operation of otch comes the insulation of mobile lead 2 and correspondingly prolongs side 10a and 10b.After the face contact, the width of receiving slit 10 is corresponding to the size in line footpath.

When the width of cutting fork 7 and 8 is big, can the contact of increasing face.

Fig. 3 a has showed: by cutting fork 7 and 8(Fig. 3) insulation of scratching lead 2 with wedge mouth shape.Lead 2 further depressions are entered position shown in Figure 3, obtain desirable slight face contact by desired contact pressure, the desired respective wire of desired contact pressure and syndeton is suitable.

For example can limit the insertion depth of lead 2 with supporting surface 12, supporting surface 12 is parts of the central component 18 of coupling 1.

Can imagine: also can constitute connector 1 under the situation that does not have central block 18, but this has just used two corner- shape components 14 and 15, corner-shape component is bound up mutually by coupling component (not drawing among the figure).

Fig. 4 and Fig. 5 have showed further concrete manifestation of the present invention.

In this case, connector 1 just is made up of the support 16 and 17 of two hook-types, here, cuts and pitches 7 sizes that contact with 8 width decision face.

Electric wire connecting junction 1 itself is fit to insert common LSA-PLUS wire clamp shown in Figure 1.Also can use the insertion and the taking-up instrument of known LSA system.
