Description
Technical field
The present invention relates to a kind of according to claim 1 electric switchgear as described in the preamble and a kind of according to claim 5 electric tool as described in the preamble.
Background technology
Such hand electric tool can be to for example battery-driven screwdriver of rig, electric screwdriver, angel grinder or the like.
Electric tool has the shell of a band handle, and the electric switch with the manual operating mechanism of an energy is housed in shell, is used to start and close hand electric tool.Can regulate the rotating speed of electric tool when needed according to the position of operating mechanism.If make the user of hand electric tool can adjust other function, the band that for example is used for the instrument installation head of the turn of the screw impacts the pulse function of rotating, and switch block is arranged in shell for this reason.Being used for manually turning on and off these other function operations parts is equipped at this switch block.Because switch block is positioned at the shell of electric tool, switch block is generally using dorsad and is installing.On the contrary, functional unit is towards using installation.
In order to come the master cock parts by functional unit, these two parts directly are close to mutually.Owing in the manual and electric tool outer casing and/or on the position reason, the switching device of being made up of switch block and functional unit optimally is not provided with in some cases.
Summary of the invention
Task of the present invention is that the degree of freedom that raising switch block and/or functional unit are arranged particularly provides a kind of functional unit therein and switch block layout spaced apart.
This task uses the electric tool of the type of the electric switchgear of type of the feature that is shown by claim 1 and the feature that shows by claim 5 to solve.
In according to electric switchgear of the present invention, between functional unit and switch block, arrange a plastic components like this, make the power that is applied on the functional unit by the operator to be delivered on the switch block by plastic components.Thereby functional unit can be disposed on the interior correct position of electric tool shell, and is particularly spaced apart with the operating mechanism of the on/off switch that is used for electric tool, improves the human engineering for the user thus.Can arrange plastic components like this, plastic components is guided in shell at least in part.Other structure of the present invention is the object of dependent claims.
This plastic components can be made the flat linear parts with the flexibility of slide unit form effect.Functional unit equally also can be done the mobile slide unit that is in line.Switch block is made up of a Hall element and a magnet in expansion structure.Wherein, magnet can so move by plastic components, makes Hall element produce a switching signal when the manual manipulation functional unit.
In the shell of electric tool, pin, strut rail etc. can be arranged, be used for pointwise ground guiding plastic components.In addition, plastic components also can be directed along a part of wall of shell.Can advise, functional unit is arranged on the back side of shell, particularly be arranged in the top of electric tool handle.This, outer switch parts can be arranged on the electric switch of hand electric tool, particularly are arranged on the switch case of this switch.The pass can be split in this case easily together with the switch block cabling, and therefore the danger that the user makes a mistake can be got rid of reliably between operating mechanism and functional unit.A part of for this reason switch block, Hall element for example, even protectorate is positioned at switch case.
The advantage that obtains by the present invention can be disposed on the electric tool shell one on the favourable position of user's ergonomic particularly in, functional unit.On the contrary, it is interior on the particularly advantageous position of performance switching function that switch block can be arranged in the electric tool shell, perhaps also can arrange in the enclosure for using on the suitable position.In addition according to switching device of the present invention installation and cheap easily.
Description of drawings
One embodiment of the present of invention are shown in the drawings, and below it are described in detail.In the accompanying drawing:
Fig. 1 is the cutaway view of the shell of a hand electric tool; And
Fig. 2 shell that the II direction is seen from Fig. 1, wherein shell is partly cut open.
Embodiment
Hand electric tool 1 in Fig. 1 can be a rig, an electric screwdriver, a battery-driven screwdriver, an angel grinder or the like, can see that it has a shell 2 and a handle 3.In shell 2, an electric switch 4 that is used to start and cut out hand electric tool 1 is housed in the handle 3 of shell 2 more precisely.Switch 4 has can the person of being operated a manual operating mechanism 5 that moves for this reason.Hand electric tool 1 can be equipped with an electronic installation to be used to control rotating speed when needed, makes the operator regulate rotating speed according to the position of operating mechanism 5.Electronic installation is positioned at the switch case 15 of switch 4 suitably.
Hand electric tool 1 additionally has a switching device 6, and it for example is used to start the pulse function of hand electric tool 1.When turning round with the pulse function of connecting, the instrument installation head of hand electric tool 1 is carried out ballistic motion for the work of the turn of the screw, so that with easy mode screw entirely is screwed into.Switching device 6 is made up of a switch block 7 and a functional unit 8 that is equipped on switch block 7 that is positioned at shell 2.Switch block 7 is positioned at shell 2 inside, and is mounted in the enclosure to the operator dorsad thus.On the contrary, be installed on the shell 2 to functional unit 8 oriented manipulation persons, so that the operator can operate by hand.For the reason of safe manoeuvring, functional unit 8 is arranged in the back side of shell 2, more precisely the top of the handle 3 of hand electric tool 1.Thereby make functional unit 8 and switch block 7 spaced apart.The plastic components 9 that is arranged between functional unit 8 and the switch block 7 passes to switch block 7 to the power that are applied on the functional unit 8 by the operator, make it possible to switch away from switch block 7.
In another kind of structure, plastic components 9 is made the linear parts of flexible flat of slide unit form.Functional unit 8 equally also can be made of the slide unit that a straight line moves, and as seeing from Fig. 2, switching device 6 can be handled by the operator by sliding like this.On slide unit 8, be fixed with a flexible keeper 10, guiding in its chute 11 on shell 2.Two position locations are arranged in chute 11, keeper 10 can corresponding to switch block 7 open or scram position enters this two position locations.
As seen from Figure 1, plastic components 9 is directed in shell 2 at least in part, prevents from thus to be hooked in shell 2 etc.Pin 12, strut rail etc. are used at shell 2 pointwises ground guiding plastic components 9, and when needed along the part guiding plastic components 9 of the wall 13 of shell 2.
