Description

Carbon brush holder

Technical field

The utility model is relevant with carbon brush for motor, particularly about a kind of carbon brush holder.

Background technology

A kind of carbon brush holder structure commonly used, it is mutually chimeric and form to include a pedestal and a bronze medal seat substantially, and this copper seat has a tubular body that is formed by the copper material system of taking out, and one is located on this body and protruding this pedestal microscler guide-joining plate outward that is exposed to by a rivet riveting.

Because, this carbon brush holder is when reality is used, usually the end that this guide-joining plate is protruded outwards bends so that energising is used, the rivet that causes this body of riveted and this guide-joining plate is easily because of being subjected to external force to pull the generation elongation strain, making this guide-joining plate is to produce between fulcrum and this body to pivot to become flexible with this rivet, and generation loose contact therebetween produces arc spark when energising.

Have the dealer to adopt a kind of carbon brush holder at present, by a bronze medal seat and mutual chimeric the forming of a pedestal, this copper seat is formed through washing off continuously by a copper sheet this carbon brush holder equally, and it has a body, and this body one end one is extended a guide-joining plate.

Though this kind structure solves the loosening problem of aforementioned riveted, because this copper seat is one of the forming,, make the generation deformation of this guide-joining plate and this body junction easily when user's application of force during with this guide-joining plate bending, influence combining of pedestal and this body.

The utility model content

Main purpose of the present utility model is to provide a kind of carbon brush holder, can make that guide-joining plate and body are firm to be combined.

Another purpose of the present utility model is to provide a kind of carbon brush holder, when the stressed bending of guide-joining plate, does not influence combining of copper seat and pedestal.

For achieving the above object, carbon brush holder of the present utility model includes:

One pedestal has a containing hole;

One bronze medal seat has a tubulose and is incorporated into body and in this containing hole and is connected on this body and stretches out the outer guide-joining plate of this containing hole; This guide-joining plate generally is the lengthy motion picture shape and has two relative long lateral margins, it is characterized in that:

This guide-joining plate also has a light filling bar, and a long lateral margin wherein extends to another long lateral margin certainly.

The body of this copper seat is taken out by copper material and is made shape, and this guide-joining plate riveting is located on this body, makes the light filling bar of this guide-joining plate be positioned at outside the containing hole of this pedestal.

This copper seat washes off shaping by copper sheet, and this guide-joining plate is protruded out by an end of this body, and this light filling bar is located at this guide-joining plate near this body place.

Two long sides of this guide-joining plate are respectively established a breach in this light filling bar place.

This light filling bar is pressed on this guide-joining plate in the mode of punching press and is established one and traverse the otch of these guide-joining plate two long sides and form.

This light filling bar is pressed on this guide-joining plate in the mode of punching press and is established one and traverse the rectangular recess of these guide-joining plate two long sides and form.

Description of drawings

Conjunction with figs. is lifted some preferred embodiments structure of the present utility model and function is elaborated, and the first brief description of wherein used accompanying drawing is as follows:

Fig. 1 is the three-dimensional exploded view of the utility model first preferred embodiment;

Fig. 2 is the stereogram of the utility model first preferred embodiment;

Fig. 3 is the stereogram of the utility model second preferred embodiment;

Fig. 4 is the stereogram of the utility model the 3rd preferred embodiment; And

Fig. 5 is the copper seat schematic diagram of the utility model the 3rd preferred embodiment.

Embodiment

See also Fig. 1, the carbon brush holder that the utility model first preferred embodiment is provided, this carbon brush holder representative figure number in the present embodiment is 10, includes:

One pedestal (20) is to make with the plastic material injection molding, has a containing hole (21).

One bronze medal seat (30), has the tubular body (31) that the copper material system of taking out forms, an and copper lengthy motion picture shape guide-joining plate (32), this guide-joining plate (32) has two relative long lateral margins (33), in addition, also have a light filling bar (34) on this guide-joining plate (32), this light filling bar (34) is to establish an otch that traverses the two long lateral margins (33) of this guide-joining plate (32) by this guide-joining plate (32) towards the one side pressure of this body to be formed.

One end of this guide-joining plate (32) is located on the outer tube wall of this body (31) with a rivet (35) riveting, and this body (31) is inserted in the containing hole (21) of this pedestal (20) again, this guide-joining plate (32) is convexedly stretched in outside the containing hole (21) of this pedestal (20), and this light filling bar (34) also is positioned at outside the containing hole (21) of this pedestal (21) simultaneously.

Via above-mentioned structure, design by this light filling bar (34), when making the stressed bending of this guide-joining plate (32), can stop or reduce the transmission of the power of bending by this light filling bar (34), and feasible not reason bending and the generation prolongation distortion of rivet (35) that connects this body (31) and this guide-joining plate (32) become flexible and can avoid this guide-joining plate (32) and this body (31) to produce.

See also shown in Figure 3, carbon brush holder (40) for the utility model second preferred embodiment, its structure and the foregoing description are roughly the same, this carbon brush holder (40) has a pedestal (41) and a bronze medal seat (42), wherein, the guide-joining plate (43) of this copper seat (42) is gone up the one side of this copper seat (42) body (45) relatively and is pressed and be provided with a rectangular recess that traverses these guide-joining plate (43) two long lateral margins (46), make this groove section form a light filling bar (44), so, this light filling bar (44) has the effect that stops or reduce the power of bending equally.

The body of copper seat is to form with the copper material system of taking out in the previous embodiment, then again the guide-joining plate riveting is established on it and form the copper seat, certainly, the mode that the copper seat can also wash off is integrally formed, see also Fig. 4, it is the carbon brush holder (50) that is provided for the utility model the 3rd preferred embodiment, the copper seat (51) of this carbon brush holder (50) is to form (as shown in Figure 5) in the mode that washes off by a copper sheet, have a body (52) and a guide-joining plate (53) that protrudes out by these body (52) one ends, this guide-joining plate (53) locates to be provided with a light filling bar (54) near this body (52), and two long sides (55) of this guide-joining plate (53) are located inwardly recessed slightly and each self-forming one breach (56) in this light filling bar (54).

So that energising when using, this light filling bar (54) has the effect that stops bending power to user's desire with this guide-joining plate (53) bending, makes this guide-joining plate (53) bend easily and produces between the body (52) that is unlikely to make this copper seat (51) and this pedestal (57) and become flexible.
