Abstract
A bending protection sleeve (1) has a first sleeve block (2), which is located at one end thereof and can be inserted into a machine casing and a second sleeve block, which is adjacent to the sleeve block (2) and leads from the machine casing to the outside. A sausage-shaped edge portion (6) is formed integrally on the end portion of the second sleeve block (3), which forms an opening (4) from which a power cable (5) is led out. The outline of the edge portion (6) is defined, so that the bending of the power cable (5) led out of the bending protection sleeve (1) is limited to a maximum allowable bending radius (R).
Description
Technical field
The present invention relates to be used for hand electric device, the particularly bending protection sleeve of hand held power machine power line; here; bending protection sleeve has first section of can insert in the device case an end, second section of stretching from device case links to each other with first section.
Particularly in hand electric device, for example hand held power machine, the power line that inserts in the device case should be soft as far as possible, makes it hinder the operation of device as few as possible.When adopting the work of hand electric device, power line just in time is subjected to very strong bend loading at the position of coming out from device case, therefore exists because very high bend loading makes the danger of the thread breakage in the power line.
Background technology
For the bend loading that makes power line keeps as far as possible little; with for example disclosed the same by DE19847456A1, DE19924551A1 or DE4344635A1; a bending protection sleeve that inserts in the device case is set, and power line passes this sleeve pipe access to plant housing or comes out from device case.Such bending protection sleeve directly provides good bending protection for power line at the position of access to plant housing.In general, adopt known bending protection sleeve still can not avoid power line to suffer high bend loading in the place of coming out from bending protection sleeve in the electric device outside.
Summary of the invention
Therefore, the objective of the invention is, a kind of bending protection sleeve of the described type of beginning is described, it can make the power line that belongs to the hand electric device prevent the effect of high bend loading as well as possiblely.
The present invention proposes a kind of bending protection sleeve that is used for the power line of hand electric device; wherein; bending protection sleeve has first section of can insert in the device case an end; second section of stretching from device case links to each other with this first section; wherein; a projection is shaped on the end of an outlet that is configured for power line of second section; its exterior contour is determined size like this; make a power line that comes out from bending protection sleeve; when it during around described convex curved; its bending radius is not less than a minimum bending radius that allows, and wherein, described projection being provided with can be improved its flexible groove.
Described purpose reaches by such scheme.
Exactly, projection makes the power line that comes out from bending protection sleeve can not must be made its radius be lower than the minimum bending radius that allows by bending at this position.Adopt simple method to prevent that power line from fractureing owing to bend loading is too high by this.
Other favorable structures of the present invention from the following describes, have been known.
Projection can have various shape.For example it can have a shape of dripping towards the outlet edge thickening, perhaps can be that taper or mushroom-shaped constitute.The convex surfaces geometry sizes that will contact with power line is conclusive.It is the possible bending radius that its shape has determined power line minimum in bending protection sleeve outlet scope.
In order to make projection keep elasticity as far as possible, groove can be set within it, for example these grooves can be one or more with respect to the sleeve pipe longitudinal axis diametrically around groove.In an advantageous manner radial loop around groove in be provided with the brace that their wall is connected, they prevent that projection is out of shape by the effect of power line too doughtily.
Description of drawings
At length introduced the present invention by means of a plurality of embodiment illustrated in the accompanying drawings below.Shown in the figure:
Fig. 1 a has the external view of the bending protection sleeve that drips the shape projection and an A-A longitudinal section that Fig. 1 b is sleeve pipe,
Fig. 2 a has the external view of bending protection sleeve of mushroom-shaped projection and a B-B longitudinal section that Fig. 2 b is sleeve pipe,
Fig. 3 a has hemisphere jut and the three-dimensional external view of the bending protection sleeve that embeds the groove in it and the C-C longitudinal section that Fig. 3 b is sleeve pipe.
Embodiment
The bending protection sleeve 1 of the power line that is used for hand electric device, particularly hand held power machine has been shown in Fig. 1 a and Fig. 1 b.Here, Fig. 1 a shows the external view of bending protection sleeve 1 and the A-A longitudinal section that Fig. 1 b shows bending protection sleeve 1.Bending protection sleeve 1 basically by two sections, form for first section 2 and second sections 3, first section constitutes like this, makes it can be fixed in the device case, come from the device case pass-out second section 3 links to each other with first section 2.An outlet 4 that is used for power line 5 is arranged on second section 3 end, and this power line passes bending protection sleeve 1 stretching, extension and enters in the housing of hand electric device.
Bending protection sleeve 1 can not stop power line 5 in outlet 4 places bending.If power line 5 bendings are so big, promptly, then power line 5 is harmful to less than the permission radius of curvature R of minimum.In order to prevent this point, projection 6 of surrounding outlet 4 on being shaped on second section 3 the end of bending protection sleeve 1.The outline of this projection 6 is determined size like this, makes round the bending radius of the power line 5 of protruding 6 bendings and is not less than the minimum radius of curvature R that allows.Minimum permission radius of curvature R approximately is 1.5 times of power line 5 diameter D.Illustrated that at the A-A of the bending protection sleeve shown in Fig. 1 b 1 longitudinal section projection 6 has determined the radius of curvature R of power line 5 in outlet 4 scopes fatefully.
Has one towards 4 heavy-edge shapes of outlet in the projection 6 shown in Fig. 1 a and the 1b.Fig. 2 a, 2b and 3a, 3b show other shape of projection 6.
Fig. 2 a shows the external view of bending protection sleeve 7 and the B-B sectional side elevation that Fig. 2 b shows bending protection sleeve 7, and it has first section 8 of being fixed in the device case and stretching from device case of linking to each other therewith second section 9 equally.There is a projection 11 second section 9 end in cable outlet 10 scopes, it in this embodiment roughly mushroom-shaped constitute.
Another kind of bending protection sleeve 12 has been shown in Fig. 3 a, 3b, and here, Fig. 3 a shows the three-dimensional external view of this bending protection sleeve 12, and Fig. 3 b shows the C-C longitudinal section of this bending protection sleeve 12.This bending protection sleeve 12 also has first section 13 that housing with electric device is fixed together, stretch from housing in addition, link to each other with first section second section 14.Here, the projection that goes out at cable outlet 15 scope internal shapings on second section 14 end has the shape of a ball or the shape of a ball that scabbles.
In order to make projection 16 certain elasticity be arranged, be provided with on this projection one or more with respect to the sleeve pipe longitudinal axis diametrically around groove 17,18 and 19.Adopt reasonable manner, in groove 17,18,19, have the interconnective brace 20 of their wall.These braces 20 are responsible for making projection 16 that certain stability is arranged, like this, and the radius of curvature R that the degree round the power line pressing projection of protruding 16 bendings can not make the bending radius of cable allow less than minimum.
Other also can be provided with groove and brace in the convex shape shown in Fig. 1 a, 1b and 2a, the 2b.
Different with the embodiment that illustrates previously is can select the suitable every kind shape of bend radius limited on a minimum permissible value with power line for projection.
