Abstract
The invention relates to a brush holder which has a holder housing and at least one fastening lug projecting laterally from the holder housing. The fastening lug is provided with an upwardly directed bent portion and a return part extending as far as the outside of the holder housing. The invention also relates to a method of producing such a brush holder.
Description
Technical field
The present invention relates to a kind of brush holder.
Background technology
The known carbon brush that is used for contacting the commutator of rotation in brush motor correspondingly is arranged in the brush holder.Here, carbon brush links to each other with spring, and this spring compresses corresponding carbon brush towards the direction of commutator.During installation, by holding device corresponding carbon brush is remained on the installation site, on this installation site, carbon brush has a desired distance apart from commutator.When end was installed, holding device was released, thereby pushed carbon brush and contact commutator by the power of spring towards the direction of commutator.Brush holder is fixed on the brush holder.For example realize this fixing by the supersonic welding termination process or by hot punching out.
The applicant's a example that is fixed on the brush holder on the brush plate is shown in Figure 1.
Here shown brush holder 2 has fixation clip 7 and 8, and these fixation clips are respectively arranged with punching 7c, 8c.In the supersonic welding termination process or in hot punching out, melt 3,4 enters into these punchings, and these melts are used for a brush holder 2 and are fixed on the brush plate 1 by expectation after cooling.
Have retainer housing 2a at the brush holder shown in Fig. 12, this retainer housing 2a has rear wall 2b, and spring 5 is supported on the inboard of this rear wall 2b.The other end of spring 5 is pressed on the carbon brush 6 that is arranged on retainer housing 2a inside equally, and this carbon brush 6 stretches out from the front side of retainer housing down in working order slightly, and here contacts with commutator 11.The upside of retainer housing 2a is provided with contact openings 10, and the electrically contacting by this contact openings 10 of carbon brush 6 that is positioned at the retainer enclosure interior realizes.
Fig. 2 shows the sketch along the cutaway view of cutting line A-A ' shown in Figure 1 of device shown in Figure 1, and in Fig. 2, the carbon brush that is arranged on the retainer enclosure interior is not illustrated.In addition, from Fig. 2, can be clear that, brush holder 2 is fixed on the brush plate 1 by following method, promptly after carrying out supersonic welding termination process or hot punching out, the melt 3 that solidifies is directed in the fixation clip 7 by punching 7c, and outwards promptly comes out left and to the right in the accompanying drawings on the top of punching.
In addition, be arranged on the contact openings 10 of the upside of retainer housing 2a as can see from Figure 2.
In addition, as can see from Figure 2, retainer housing 2a is provided with slit 9 near the melt 3 that solidifies, and this slit results from the bending ram process.
Verified, in hot punching out or supersonic welding termination process, melt passes through the inside that this slit 9 arrives retainer housing 2a in the mode of not expecting, solidifies there and the motion of obstruction carbon brush in the retainer housing in work afterwards.
Summary of the invention
The objective of the invention is to overcome shortcoming described above.
This purpose realizes by the brush holder with feature of explanation in claim 1.Favourable design of the present invention and improvement project illustrate in dependent claims 2-7.The theme of claim 8 is a kind of methods of making the brush housing.
Advantage of the present invention is that especially the melt that is produced can not arrive the inside of retainer housing and solidify there in hot punching out or supersonic welding termination process.Therefore, in work the obstruction to the motion of carbon brush in the retainer housing that causes by the melt that solidifies can never appear the time.This advantage ascribes to, and according to the present invention, the fixation clip of brush holder is respectively arranged with bend, and has the portion of returning, and this portion of returning extends to the outside of retainer housing 2a and covers the slit that is produced during fabrication 9 of retainer housing.Therefore the melt that is produced can not enter in the slit 9.
Description of drawings
Other favorable characteristics of the present invention provides by explained later of the present invention with reference to Fig. 3 and 4.
Fig. 3 is the cutaway view that has by the device of brush holder of the present invention; And
Fig. 4 is the perspective view by brush holder of the present invention.
Embodiment
Fig. 3 shows the cutaway view that has by the device of brush holder 2 of the present invention.This brush holder 2 is fixed on the brush plate 1.Realize this fixing by following method, promptly by hot punching out or supersonic welding termination process, melt 3 is conducted through the as one man overlapping punching 7c of fixation clip 7, is cured then.
With compare at the brush holder shown in Fig. 2, fixation clip 7 is constructed longlyer, and has bend 7a and return the 7b of portion, this returns the outside that the 7b of portion arrives retainer housing 2a always.Therefore, the slit 9 that is used for the melt that produced during hot punching out or supersonic welding termination process can not enter.Therefore, got rid of the generation of following situation: promptly melt can enter into the inside of retainer housing 2a by slit 9, solidifies there, and hinder the motion of carbon brush in the retainer housing when work.
Shown in Figure 3 is by the structural member of bending ram automatics by the one of brass sheet, steel or copper one-tenth by brush holder of the present invention.According to the present invention, in the bending ram automatics, realize the crooked of fixation clip 7,8 and make turning back to the outside of retainer housing 2a always, so be closed on the outside of retainer housing by the slit 9 that manufacture process produced accordingly in the retainer housing as the sweep that returns the 7b of portion, 8b.
Figure 4 illustrates the perspective view of brush holder of the present invention.Can be clear that from this view brush holder 2 is provided with the retainer housing 2a with rear wall 2b; Fixation clip 7; Fixation clip 8; And be arranged on contact openings 10 on the upside of brush holder.The front side of retainer housing 2a is opened wide, and therefore in work afterwards, the carbon brush that is placed in the retainer enclosure interior can stretch out forward from the retainer housing, thus contact converter.
In addition, as can see from Figure 4, fixation clip 7 has a bend 7a and the 7b of the portion that returns that extends to the retainer housing 2a outside up.In addition, fixation clip 7 is provided with the punching 7c of overlapping setting as one man, when being fixed on brush holder on the brush plate, promptly in hot punching out or supersonic welding termination process, melt can add by these punchings, and this melt solidifies and produces desired fixing then.
Be arranged on fixation clip 8 on another longitudinal side of retainer housing 2a have one up bend 8a and the 8b of the portion that returns on outside that extends to retainer housing 2a.In addition, fixation clip 8 is provided with the punching 8c of overlapping setting as one man, when being fixed on brush holder on the brush plate, promptly in hot punching out or supersonic welding termination process, melt can add by this punching, and this melt solidifies and produces desired fixing then.
Advantage of the present invention not only is in hot punching out or supersonic welding termination process, do not have the melt can Enter in the inside of retainer housing, and be brush holder fixedly being improved on brush plate, Because owing to fixation clip is improved by bend and the section of returning, thereby so that each fixation clip The melt of more curing is arranged to fixedly making contributions.
