Abstract

The utility model relates to an output line bolt of voltage regulator for vehicle, which is aiming at the problem that the prior output line bolt has complicated production process, low finished-product ratio and poor connection reliability. The utility model comprises a bolt, a pre-buried metal sheet and a carbon brush support, the pre-buried metal sheet is arranged at the end cap of the bolt, the utility model is characterized in that a lining which has an interference fit with the bolt is molded in the carbon brush support, the bolt is fixed by the lining, the utility model has the advantages that the bolt is fixed by the lining, both the bolt and the lining adopt the interference fit, so the utility model not only has reliable connection but also has good conductive property to simplify production process, the bolt is pressed into the lining and then is molded in the carbon brush support so as to reduce the step of assembling nut to save production time and lower the production cost, as the lining and the bolt are molded in the carbon brush support, the carbon brush support will not be subject to the pressure action during production, moreover one-step molding can be realized so as to enhance the finished product ratio.

Description

Voltage regulator for automobile outlet bolt

Technical field

The utility model belongs to a kind of alternator for vehicle parts, particularly a kind of voltage regulator for automobile outlet bolt.

Background technology

The outlet bolt is parts on the alternator for vehicle voltage regulator, outlet bolt of the prior art as shown in Figure 2, it is mainly given by bolt 1, nut 5, metal and buries sheet 4 and carbon brush holder 3 constitutes.Wherein, metal gives and buries sheet 4 and be injection-moulded in the carbon brush holder 3, and bolt 1 is pressed into metal with certain pressure and gives and burying in the sheet 4, and interference fit is fixed with 5 pairs of bolts 1 of nut more between the two.The problem that above-mentioned outlet bolt exists is: 1, complex manufacturing, the assembling link is many, during assembling, metal to be given earlier and bury sheet 4 and be injection-moulded in the carbon brush holder 3, and then bolt 1 is pressed into metal gives and burying in the sheet 4, also will be fixed with 5 pairs of bolts 1 of nut at last, used man-hour is more, the assembly cost height.2, giving to metal when burying in the sheet 4 dump bolt 1, can damage carbon brush holder 3, the rate of finished products of production is reduced if pressure control is improper.3, bolt 1 is mainly fixing by nut 5, because the vibration of vehicle is bigger, usually can make nut 5 loosening, and the reliability of connection is relatively poor.

Summary of the invention

The technical problems to be solved in the utility model is, overcome problems such as complex manufacturing, finished product rate that existing outlet bolt exists are low, connection reliability difference, provide that a kind of production technology is simple, finished product rate height, connect reliable voltage regulator for automobile outlet bolt.

The utility model comprises that bolt, metal give and buries sheet and carbon brush holder, and metal gives and buries the end cap place that sheet is installed in bolt, and its special character is, is injected with the lining with the bolt interference fit in carbon brush holder, with lining bolt fixed.

Advantage of the present utility model is:

1, with lining bolt is fixed, and both adopt interference fit, not only firm and reliable connection also has good electrical conductivity, has improved electric conductivity.

2, simplify production technology, after bolt is pressed in the lining, has been injected into again and gets final product in the carbon brush holder, reduced this link of assembling nut, saved the production time, reduced producing cost.

3, lining and bolt are injected in the carbon brush holder, thereby the carbon brush holder effect that can not be under pressure in process of production, and one-shot forming, have improved the rate of finished products of product.

Fig. 2 is the structural representation of existing outlet bolt.

Embodiment

As shown in Figure 1, the utility model comprises that bolt 1, metal give and buries sheet 4 and carbon brush holder 3, and metal gives and buries the end cap place that sheet 4 is installed in bolt 1, is injected with the lining 2 with bolt 1 interference fit in carbon brush holder 3, fixed with 2 pairs of bolts 1 of lining; During assembling, earlier metal is given and bury the end cap place that sheet 4 is placed on bolt 1, again bolt 1 is pressed in the lining 2, bury sheet 4 distortion in order to prevent that metal from giving, metal gives burying between sheet 4 and the bolt 1 and adopts matched in clearance, then, again bolt 1, lining 2 and the metal that assembles given bury sheet 4 together injection mo(u)lding be carbon brush holder 3.

Claims

1, a kind of voltage regulator for automobile outlet bolt, it comprises that bolt, metal give and buries sheet and carbon brush holder that metal gives and buries the end cap place that sheet is installed in bolt, it is characterized in that, is injected with the lining with the bolt interference fit in carbon brush holder.
