Description

Switch wire connection device

Technical field

The utility model is relevant with a kind of switch wire connection device; Special and a kind of switch wire connection device is provided with limiter, contact, and combination metal clips, is beneficial to direct pivot joint wire, and, make limiter under the condition with high stiffness, auxiliary fixing relevant with the invention of specification metal clips motion path.

Background technology

Switch wire connection device is a kind of power switch component with connecting circuit, circuit, is installed on electronics, the guidance panel of motor device or distribution box, in order to connection wiring circuit.Switch wire connection application of installation is covered by conductive component in insulation shell (normally plastic material is made), screw interlocking electronics, the wiring circuit of motor device or wire, coordinate the operation of shift knob, control energising or the power-off of conductive component and wiring circuit or wire, and set up the effect of open and close circuit power, it is prior art; Such as, No. 103206602nd, Taiwan " switch terminal holder structure " Patent Case, provides a typical embodiment.

One to use and problem in structural design is that insulation shell is provided with the interlocking hole of the plug wire hole that communicates and operation screw in operation about this kind of switch wire connection device, provides human users's instrument control wire that screw closure enters from plug wire hole.In practical operation, must first make screw position in pine oil state, to allow wire insert plug wire hole; When screw position is in pine oil state, screw has deflection situation, therefore often causes human users's screw to aim at the operation of sealed wire and electric contact (or claiming electrical terminals), becomes trouble and difficulty.

In order to improve the problems referred to above, old law also reveal that a kind of guide channel and sliver are set on insulation shell and electric contact, structure that spring coordinates.But described structure not only more complicated, adds manufacturing cost; Further, usually must increase housing volume, interfere to avoid this guiding structural and conductive component to produce.Moreover, increase evolution and designer trends that housing volume is also unfavorable for switch terminal equipment miniaturization.

Some environment used (running of such as machinery equipment can produce vibrations situation), the process of Long-Time Service, easily makes loosened screw, causes the situation that wire rod gets loose.Particularly, the work that the pivot joint operation of screw mechanism and wire or wire rod all must use instrument could operate locking, loosen, relatively also cumbersome.

Old law also discloses the design of a kind of cooperation housing interior structure, and application external form becomes the metal clips of α profile, and compacting wire or wire rod, replace the structure of screw mechanism interlocking wire.But, just as those have the knack of known to the people of this technology, α type metal clips is done out of trade except what be bent into special shape, metal clips also must offer oral area, make its other end through oral area, oral area forms swingable structure, to suppress wire.Therefore, α type metal clips is cumbersome on structure fabrication, complicated; And this situation is not desired by us.

Representational, these reference datas show in the skill about switch wire connection device and correlation combiner design aspect; If the textural association of this insulation shell and conductive component, electric contact, switch is considered in overline design, make it construct to be different from conventional, its use form can be changed, and be different from old law; In fact, its range of application can also be increased.Such as, meeting under the condition not increasing switch wire connection device volume, make their structure be easy to make and operation, improve and often know that operation screw aims at the operation trouble of sealed wire and electric contact and the situation etc. of the labyrinth such as difficulty, insulation shell Integrated guidance groove, sliver, spring, application α type metal clips; Or make this switch wire connection device allow that personnel do not need use instrument further, direct control wire inserts pivot joint electric contact, and electric contact is being met under rigidity or the higher condition of hardness, have the means such as good, the auxiliary fixing metal shell fragment of conductivity and guiding metal clips motion path.And these problems in above-mentioned reference data all not by concrete teaching or exposure.

Fig. 2 particularly illustrates after personnel's direct control wire 90 inserts plug wire hole 12, and wire 90 is pressed against on contact first end 61 and forms conducting state by the tail end 76 of metal clips second segment 72.Now, conducting element 30 is positioned at the position contacted with contact second end 62, and forms "on" position.If personnel's push switch button 20, drive conducting element 30 towards Figure below displacement, make conductive component 30 leave contact second end 62, then form off-position.

Fig. 1, Fig. 2 also illustrate metal clips 70 and are housed in structure kenel inside limiter 50, at least make the motion path of limiter Second Edge 52 and the 4th limit 54 common specification metal clips second segment 72, and can not to dual-side beat, this contributes to increasing the motion of metal clips 70 and the stability of operation metal clips 70 composite conductor 90.

Particularly, when operation wire 90 inserts the space 55 of housing cavity 11 and limiter 50, wire 90 can be limited in the limiter space 55 of high rigidity, therefore the bare metal end not having known skill wire is inserted wound or is scratched the situation of housing, or because of operating environment, occasion (such as, machinery equipment running vibrations etc.) or carelessness collision, causes that wire is excessive at enclosure interior pendulum angle, torsion etc. and strut the situation of housing.

The imaginary line part of Fig. 2 shows personnel and can stretch in chamber 11 and limiter space 55 from housing 10 lower end one handle hole 15 by operation tool 80, promote metal clips second segment 72, second segment tail end 76 is made to leave wire 90, remove the state that metal clips second segment 72 pushes down wire 90, allow personnel directly can remove wire 90 and leave housing 10.

In a feasible embodiment, according to the shape of housing cavity 11, Second Edge 52, the 4th limit 54 of limiter 50 are formed with recess 52b, 54b, reliably unify the shoulder 16 be formed on housing 10 or chamber 11, make the combination of limiter 50 and housing 10 more firm.

Please refer to Fig. 3, this limiter 50 and contact 60 form integrated structure.That is, contact first end 61 and limiter first limit 51 form the structure kenel that one is connected.

Refer to Fig. 4, Fig. 5, disclose the embodiment that electric contact 40 1 is revised.The combination kenel of foundation housing 10 (or chamber 11) and shift knob 20, contact second end 62 of this electric contact 40 bends towards the direction (or opening direction of Figure below or metal clips 70) in limiter space 55, extend to form a secondary end 63 (such as, making the second end 62 and secondary end 63 form the angle angle at acute angle, right angle or obtuse angle); Bend from pair end 63 towards the direction of conductive component 30 or shift knob 20 again, extend to form a tail end 64 (such as, making secondary end 63 and tail end 64 form the angle angle at acute angle, right angle or obtuse angle).

Fig. 5 shows when human users's shift knob 20 drives conductive component 30 after Figure below displacement, and conductive component 30 can touch contact tail end 64, forms "on" position.If human users's shift knob 20 drives conductive component 30 in figure during the displacement of top, conductive component 30 can leave contact tail end 64, forms off-position.
