Abstract
The invention discloses a B+ output screw structure of an auto rectifier, which consists of a B+ screw assembly, a conducting strip and a nut, and is characterized in that a plastic protective casing and a screw are integrated into a whole by a shooting technique; the conducting strip, a plain washer and the nut are arranged on the screw; the cylindrical part at the root of the screw is provided with a circular boss; and the conducting strip is rigidly connected with plane of the circular boss of the screw by the fastening the plain washer and the nut. The connection does not loosen due to the change of the external environmental temperature, so the connection reliability is obviously improved.
Description
Technical field
The present invention relates to a kind of automotive electronics, especially a kind of B+ output screw structure of auto rectifier.
Background technology
At present, the B+ output screw of existing Japan electric coating series rectifier adopts circular screw rod to add the frame mode of plastic protective sleeve.Structure screw rod and plastic protective sleeve are that matched in clearance fits together, and when conducting strip is contained on the screw rod, after nut was fastening, conducting strip lower surface and plastic protective sleeve compressed and fit together.Plastic protective sleeve is easy to crack when nut screwing clamping, on the other hand, can produce high temperature when automobile current generator is worked, and plastic protective sleeve at high temperature can produce slight aging contraction distortion.Conducting strip will become flexible like this, causes the brace loose contact, and produces bigger contact resistance between the B+ screw rod, heating rapidly under the big function of current.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, a kind of B+ output screw structure that connects reliable auto rectifier is provided.
The object of the present invention is achieved like this: a kind of B+ output screw structure of auto rectifier is made up of B+ screw rod group component, conducting strip, nut.It is characterized in that: plastic protective sleeve and B+ screw rod form one by Shooting Technique.Conducting strip, plain washer, nut are housed on screw rod, are provided with an annular boss at the thread root column part.Conducting strip is rigidly connected by plain washer and fastening the formation with screw rod annular boss plane of nut.
Beneficial effect is: owing to adopt technique scheme, fastening after the conducting strip assembling with nut, conducting strip and screw rod annular boss plane are formed be rigidly connected.This connection can not become flexible because of the variation of ambient temperature, and connection reliability obviously improves.And plastic protective sleeve and B+ screw rod be injection molded into one, and working of plastics does not stress when work, can avoid because of the dry and cracked switching performance that influences.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples;
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1.B+ screw rod group component, 2. conducting strip, 3. plain washer, 4. nut, 5. annular boss.
Embodiment
With reference to accompanying drawing, the present invention is made up of B+ screw rod group component 1, conducting strip 2, nut 4.Plastic protective sleeve and B+ screw rod group component 1 form one by Shooting Technique.Conducting strip 2, plain washer 3, nut 4 are housed on screw rod, are provided with an annular boss 5 at the thread root column part.Conducting strip 2 is rigidly connected by plain washer 3 and nut 4 fastening formation with screw rod annular boss 5 planes.
