Abstract
The utility model discloses a kind of tank commutator, form by insulating body with at the grooved commutator segment that the excircle of insulating body is evenly laid, the medial surface of described grooved commutator segment is provided with hook pin and implants in insulating body and insulating body strong bonded, it is characterized in that: every grooved commutator segment is provided with upper and lower two hook pin, mutually staggering in the short transverse of commutator between two hook pin up and down of adjacent grooved commutator segment, the commutator cylindrical that described grooved commutator segment crosses is up and down with the cylindrical shape in footpath, the cylindrical of grooved commutator segment offers soldering bonding wire groove at tip position.The utility model has the advantages that Stability Analysis of Structures, mechanical strength is high, saves cost.
Description
[technical field]
The utility model relates to a kind of tank commutator product.
[background technology]
Commutator is mainly used in electric tool, and commutator divides hook, grooved and face type three kinds, and wherein tank commutator is gained the name because bonding wire groove offered by commutator segment.In prior art, high mechanical properties requirement is reached for enabling tank commutator, maximum methods is adopted to be that the hook leg structure improving grooved commutator segment medial surface makes it and insulating body strong bonded, the technical scheme improving hook leg structure optimum is then the head width size adding hook pin, but add hook pin head width size and can bring following harmful effect: one is that hook pin periphery can reduce for the space of filling insulating matrix material, easily causes the integrally-built instability of commutator
two be adjacent hook pin head between distance can be too small, commutator segment together with insulating body during injection-compression molding adjacent commutator segment hook pin between easily come in contact, thus it is defective and occur waste product to cause commutator to detect.Further, current tank commutator generally adopts spot-welding technology and wire bonds, thus the bonding wire groove of the outer circular top part of commutator segment to offer comparatively dark, so commutator segment is usually designed to L-type, so just cause cost to increase.
[summary of the invention]
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Stability Analysis of Structures, mechanical strength high, cost-effective tank commutator.
The utility model takes following technical scheme:
A kind of tank commutator, form by insulating body with at the grooved commutator segment that the excircle of insulating body is evenly laid, the medial surface of described grooved commutator segment is provided with hook pin and implants in insulating body and insulating body strong bonded, it is characterized in that: every grooved commutator segment is provided with upper and lower two hook pin, mutually staggering in the short transverse of commutator between two hook pin up and down of adjacent grooved commutator segment.
The commutator cylindrical that described grooved commutator segment crosses is up and down with the cylindrical shape in footpath, and the cylindrical of grooved commutator segment offers soldering bonding wire groove at tip position.
The tank commutator that the utility model provides, its Advantageous Effects that can produce is: 1. mutually staggering in the short transverse of commutator between two hook pin up and down due to adjacent grooved commutator segment, enable every hook pin periphery leave greater room for filling insulating matrix material, thus the overall structure of commutator is stablized; Also the head width size of hook pin can be made to widen simultaneously, strengthen the bond strength between commutator segment and insulating body, improve the mechanical strength of tank commutator.2. tank commutator adopts soldering processes and wire bonds, and brazing temperature is low, thus the bonding wire groove of the outer circular top part of commutator segment can offer very shallow, so the cylindrical of commutator segment can be designed to equally large up and down, thus effectively reduce costs.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of tank commutator of the present utility model.
[embodiment]
As shown in the figure, tank commutator of the present utility model, form by insulating body 4 with at the grooved commutator segment 3 that the excircle of insulating body 4 is evenly laid, the medial surface of every grooved commutator segment 3 is provided with upper and lower two hook pin 1 and implants in insulating body 4 and insulating body 4 strong bonded, mutually staggering in the short transverse of commutator between two hook pin 1 up and down of adjacent grooved commutator segment 3; The commutator cylindrical that described grooved commutator segment 3 crosses is up and down with the cylindrical shape in footpath, and namely the cylindrical of grooved commutator segment 3 is designed to equally large up and down, and the cylindrical of grooved commutator segment 3 offers soldering bonding wire groove 2 at tip position.
