CN201100932Y - Contact riveting electric brush - Google Patents

Abstract

The utility model relates to an electric brush which is an important component of a sensor and in particular relates to a contact rivet joint type electric brush. Rivet type contacts are riveted on a beryllium copper bullet to combine the electric brush, and the other end of the beryllium copper bullet is installed on the electric brush. The electric brush mainly solves the technical problems that the cost of alloy wire material of an existing alloy wire electric brush is high, the molding for the head bending structure is difficult, the welding technique is complex, and the like, the electric brush adopts the beryllium copper bullet to contact a part of rivet alloy contacts, the whole structure technique is simple, the cost is comparatively low, the performance is reliable, and the electric brush is manufactured easily.

Description

Contact riveted type brush

Technical field

The utility model relates to a vitals---the brush of transducer, particularly a kind of contact riveted type brush.

Background technology

Along with further developing of auto electronic control technology, the status of automobile sensor is more and more important, and at present, a general car has approximately been installed tens to up to a hundred transducers, and the number of sensors on the limousine is nearly surplus in the of 200.In the cost ratio of bicycle, the shared share of automobile sensor is also increasing.

The automobile sensor that adopt to become the resistance voltage divider principle is in the detection of variable quantities such as angle, position is used, and is simple in structure because of it, be convenient to operation, uses very extensive on the spot.At present, such transducer, especially throttle position sensor, the external brush that adopts beryllium copper shell fragment welding alloy silk mostly, as Fig. 1, it is that a face down bonding at brushgear housing A connects beryllium copper shell fragment B one end, and this shell fragment B other end is the end of welding alloy tow C then, and the other end head of this alloy tow C is a warp architecture.This structure cost of raw material height, complex forming technology, reliability be cannot say for sure to demonstrate,prove, and the production difficulty of product strengthens.

The utility model content

The purpose of this utility model is to provide a kind of contact riveted type brush, mainly solve the technical problems such as alloy wire material cost height, head-bent shaping structures difficulty and welding procedure complexity of existing alloy silk brush, adopt the beryllium copper shell fragment, contact portion riveted joint alloy contact, total technology is simple, cost is lower, and dependable performance is easy to produce.

For achieving the above object, the technical solution of the utility model is:

A kind of contact riveted type brush is characterized in that: brush is formed with being riveted on the beryllium copper shell fragment in the rivet type contact, and this beryllium copper shell fragment other end then is installed on the brushgear housing.

Described contact riveted type brush is characterized in that: the quantity of this rivet type contact is two.

By said structure, the utlity model has following advantage:

The utility model brush adopts riveting process and rivet contact technology, is convenient to operation, with low cost and dependable performance, is convenient to very much mass production, compares with alloy silk brush, in conjunction with present domestic production status, has great advantage undoubtedly.

Description of drawings

Fig. 1 is the structural representation of existing product.

Fig. 2 is a structural representation of the present utility model.

Embodiment

See also Fig. 2, the utility model discloses a kind of contact riveted type brush.As shown in the figure: rivet type contact 2 usefulness are riveted on the beryllium copper shell fragment 1 forms brush, and this beryllium copper shell fragment 1 other end then is installed on the brushgear housing 3.The quantity of this rivet type contact 2 is two.

The mounting process step of the utility model brush is:

Adopt the contact riveting process, two rivet type contacts are riveted on the shell fragment with riveting machine, form brush, again brush is installed on the brushgear housing.

According to different useful life and operational environment, silver alloy, proof gold or other alloy can be adopted in the contact, and shell fragment generally adopts beryllium copper.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.

Claims (2)

1, a kind of contact riveted type brush is characterized in that: rivet type contact (2) are gone up and are formed brush with being riveted on beryllium copper shell fragment (1), and this beryllium copper shell fragment (1) other end then is installed on the brushgear housing (3).

2, contact according to claim 1 riveted type brush, it is characterized in that: the quantity of this rivet type contact (2) is two.
