Abstract

The utility model relates to a plug wire switch. Two parallel plug wire spaces are arranged inside a casing. The bottom surface of the utility model is provided with two plug wire holes and two back line holes which are separately communicated with the two plug wire spaces. Two terminals and two elastic blocked component parts are separately arranged in the two plug wire spaces. A conducting strip which is movably arranged inside the casing and is cross-over on the top of a terminal. One end of the conducting strip is located on the top of the other terminal. A button is pivot-arranged on the top of the casing. The conducting strip can be displaced and driven by the button when the button is pressed, which makes one end of the conducting strip contact or not contact with the other terminal. After two wires are inserted into two plug wire spaces through the two plug wire holes, the two wires are pushed and pressed by the two elastic blocked component parts and are separately contacted with two terminals. In this way, the wire is easily connected with the switch. At the same time, as a result of the design of the two back line holes, the wire can be easily exited from the switch.

Embodiment

See also Fig. 2 to Fig. 5, the plug wire switch 20 that the utility model one preferred embodiment is provided, it includes: a shell 30, and be installed in button, terminal, conducting strip and elasticity clip element etc. in this shell.

See also Fig. 6, these shell 30 inner hollow, and top and bottom ends all is permeable type.Two

plug wire spaces

35,36, about be located at the Lower Half of shell 30 inside side by side.Two

caulking grooves

37,38 are located at this two plug wires space, 35,36 1 sides, for example right side shown in the figure respectively.One bottom 34 please cooperate and consult Fig. 4, is provided with two

plug wire holes

40,42 and two and moves back

line hole

41,43, and this two moves back

line hole

41,43 and match mutually with this two

plug wire hole

40,42 respectively, and preferably, Pei Dui plug wire hole is crossing and be communicated with moving back the line hole mutually.This bottom 34 is covered on shell 30 bottoms, and is snapped in the button hole 46 of shell 30 and locatees with its clamping part 45, mutually Pei Dui plug wire hole with move back the line hole (that is, mutually 40 and 41 of pairing, and match mutually 42 and 43) communicate with this two

plug wires space

35,36 respectively.In the enforcement, the aperture of each plug wire hole is greater than the aperture of moving back the line hole.In addition, outer peripheral face two sides of this shell 30 are respectively established a snap-on 48.

One first and one

second terminal

50,55 is installed in the shell 30, and is positioned this two plug wires space, 35,36 opposite sides, left side for example shown in Figure 6 respectively.The internal face of this shell 30 is provided with raised line 321,322, make

terminal

50,55 limited by raised line and keep the location.Preferably, the first terminal 50 is one side terminal, near the limit wall of shell 30; And second terminal 55 is a center terminal, near shell central authorities.

One conducting strip 60 is installed in the first half of these shell 30 inside, is cross-placed on these center terminal 55 tops and can lifts up.These center terminal 55 tops are established one and are recessed into 56, as shown in Figure 5; The sheet of conducting strip 60 is then established the width waist 62 little than the sheet body on one's body, by this waist 62 and the cross-over connection that should be recessed into 56, conducting strip can be lifted up, can not be shifted and difficult and center terminal 55 disengagings, and conducting strip 60 keeps in touch with center terminal 55.

Two

elasticity clip elements

70,75, the shell fragment shape is made in this preferred embodiment, and is generally V-shaped, the one end is a positioning end, is embedded at this two

caulking groove

37,38 respectively, and the

other end

72,76 is one to press end, stretch into this two

plug wires space

35,36 respectively, the cross section that respectively presses

end

72,76 is V-shaped for good.

One button 80 is articulated in the pivot hole 32 on these shell 30 tops with the cylindrical articulated section 82 of its two side, push for staff, and can its to articulate position be fulcrum and angular displacement.These button 80 bottom surfaces down protrude out a post portion 84; The cylinder 88 of one flexible member 86 and a hollow constitutes the part of this button 80, and is installed in the shrinkage pool 85 of this post portion 84, and this cylinder 88 is subjected to the elasticity ejection of this flexible member 86 and keeps protruding out post portion 84 bottoms.By this, but button 80 bottoms have the effect of elastic telescopic, and press in this conducting strip 60.

The state that Fig. 2 and Fig. 6 finish for the utility model assembling, this switch 20 is installed on electric equipment or the apparatus, and these snap-ons 48 can make the switch location.

Switch provided by the utility model is easy to be connected with electric wire.See also Fig. 7, two electric wires, 90 outer field rubber are removed its heart yearn 92 is exposed, then this two electric wire is inserted switch from this two

plug wire hole

40,42, when the heart yearn 92 of electric wire inserts

plug wire space

35,36, to push by

end

72,76 elasticity that press of this two

clips element

70,75, and contact with this two-

terminal

50,55 respectively, but form conduction state.When heart yearn 92 is pressed 72,76 elastic clip of end when pulling, electric wire 90 also can't be pulled out.In Fig. 7, this button 8 is to be positioned at the OFF position, and the end 64 that touches of conducting strip 60 does not contact with the first terminal 50, so circuit is off state.

When button 80 was pressed on ON position shown in Figure 8, touching of conducting strip 60 held 64 toward bottom offsets, and is contacted with this limit terminal 50, and by this, this two-

terminal

50,55 and conducting strip 60 form on-states, can make the circuit of electric equipment form path.

Structure of the present utility model also makes electric wire separate with switch easily.See also Fig. 9, the one elongated body of rod 95 is inserted

plug wire space

35 or 36 from moving

back line hole

41 or 43, the heart yearn 92 that

end

72,76 pushes away electric wire 90 that presses with

clip element

70,75, make and press end and no longer press from both sides the heart yearn of pulling, electric wire 90 can be taken out from switch, by this, can make things convenient for the user to keep in repair or check electric equipment.

Switch provided by the utility model, and do not require that the user must have solder technology, electric wire need only be inserted switch, electric wire is connected with switch, simplify the wiring operation, make the connection of electric wire more convenient.Moreover the utility model it need not to use other equipment to connect electric wire, so can not increase extra cost

In addition, switch of the present utility model also can be easy to withdraw from electric wire, makes things convenient for the maintenance and the inspection of electric equipment.

Must explanation be that elasticity clip element does not exceed with the present embodiment those shown, for example, replaces the shell fragment of present embodiment with spring or other rubber-like objects, can reach same effect equally.

The above person only is a concrete enforcement structure of the present utility model, when not limiting scope of the present utility model with this.Any simple modification or equivalence of doing according to technology contents of the present utility model changes, and all still belongs to the scope that the utility model is contained.
