Description
Technical field
The present invention relates to a kind of coil block structure and with the magneto-electric crankshaft rotational speed sensor of the coil block structure.
Background technology
Magneto-electric crankshaft rotational speed sensor is a kind of device of test speed of crankshaft, and basic principle is：It is coil-induced to arrive
The magnetic flux change caused by permeability magnetic material and induced potential, output signal.
Pole pin, the Hard Magnetic of coil, soft magnetic materials that the structure of magneto-electric crankshaft rotational speed sensor is mainly coiled by enameled wire
Magnet, the coil of material draw metal terminal and plastic cement skeleton composition；Coil is wound on the pole pin of soft magnetic materials, and pole pin reaches biography
Outside sensor, become sensor head, pole is sold tail portion and is in close contact with magnet.The magnetic field line of magnet after magnetizing is sold across pole,
Coil has also been passed through simultaneously, reaches sensor head.
In the manufacturing process of magneto-electric crankshaft rotational speed sensor, need the magnet of hard magnetic material magnetize make its at
For permanent magnet.Also there is prodigious magnetic flux change during magnetizing.Therefore, coil can generate larger electricity of inducting at this moment
Pressure, the induced potential of entire coil can be more than 600V.
And the enameled wire of coil is a kind of copper core of polyamine esters insulating layer package, the proof voltage of insulating layer is 350V.
The voltage of maximum 600V has been over the pressure-resistant range of enameled wire between coil, is easy breakdown insulating layer, makes the copper of enameled wire
Core is exposed to outside, leads to cause short circuit between circuit, and then product failure.
Loop construction is as shown in Figure 1, the inlet wire 1 of coil reaches the bottom of wire casing along wire casing side, and carries out from inside to outside
Multi-lay winding, outlet 2 are drawn outward in the outermost layer of coil.Position due to inlet wire 1 and inlet wire feature, necessarily lead to itself and line
Each layer of circle is in direct contact.Wherein sense of the outermost layer of inlet wire 1 and coil between 3 touching position of position, the two
Raw voltage is close to maximum, therefore, is easiest to occur enameled wire at position 3 by voltage breakdown.
As shown in Figure 2, inlet wire 1 enters winding slot, extends to the bottom of winding slot.Coil expands from inside to outside
Exhibition.At the end of coiling, outlet 2 is drawn outward in outermost layer.The outermost layers of Fig. 2 coils and 1 touching position of inlet wire, the two it
Between induced potential be also maximum.Under such structure, the distance between inlet wire 1 and the outermost layer of coil D1 are approximately equal to zero,
It is breakdown that enameled wire is easily lead under high voltage.
In order to ensure that maximum induced potential will not puncture enameled wire, the method usually used is to increase casing in end of incoming cables to protect
Inlet wire is protected, can effectively improve the ability of proof voltage in this way.However, this mode is in the production process of automatic winding equipment
And it is impracticable, increase technology difficulty and cost.
Invention content
It is a primary object of the present invention in view of the deficiencies of the prior art, provide a kind of coil block structure and have the line
The magneto-electric crankshaft rotational speed sensor of coil assembly structure, with the case where not changing the magnetizing of coil block structure, winding turns
Under, the proof voltage reliability between inlet wire and coil-winding is improved, the inlet wire of existing product structure coil is overcome to magnetize
Enameled wire leads to the problem that product failure rate is high in manufacture course of products easily by high electrical breakdown in journey.
To achieve the above object, the present invention uses following technical scheme：
A kind of coil block structure, including coil rack and coil, the coil rack have winding slot, the coil around
In the winding slot of the coil rack, the wire lead slot being recessed outward is offered on the side wall of the winding slot, it is described
Wire lead slot extends to the surface of the coil rack from the winding slot from inside to outside, and the inlet wire of the coil is filled into the lead
In the recess of slot, enter in the winding slot along the wire lead slot, to the coil inlet wire and the coil outer layer around
At least there is the spacing distance generated because the inlet wire of the coil is filled into the recess between line.
Further：
The wire lead slot is upwardly extended from the bottom of the winding slot, and the inlet wire of the coil is directed to along the wire lead slot
At the bottom of the winding slot.
The depth of the wire lead slot gradually increases along from the direction of the bottom of the winding slot outward.
Depth of the wire lead slot at the bottom of the winding slot is not less than the diameter of coiling.
The bottom of the wire lead slot is the inclined-plane with pre-determined tilt angle.
It is filled into the distance between outermost layer coiling of the inlet wire and the coil in the recess of the wire lead slot no
Less than twice of winding diameter.
The width of the wire lead slot is not more than 1.5 times of winding diameter.
The coiling is enameled wire.
A kind of magneto-electric crankshaft rotational speed sensor has the coil block structure.
A kind of transformer has the coil block structure.
The present invention has the advantages that：
The coil block structure of the present invention improves the point of incoming cables of coil rack, in the position of coil rack inlet wire
Increase wire lead slot, with increase between inlet wire and each layer coiling of coil especially between the outermost layer coiling of coil away from
From, and distance is bigger, the voltage endurance capability of coil is higher.It may insure in magnetization process in this way, the enameled wire of coil is hit
The probability worn reduces.
By the present invention coil block structure be used for magneto-electric crankshaft rotational speed sensor, can not change magnetize, coiling
In the case of the number of turns, the proof voltage reliability between inlet wire and coiling is improved, the caused product failure in magnetization process is prevented, carries
High crankshaft rotational speed sensor makes the reliability of yield and product, and the inlet wire of existing product structure coil is effectively overcome to magnetize
Lead to the problem that product failure rate is high in manufacture course of products easily by high electrical breakdown between the coiling of coil in the process.
In addition, the structure by the way that wire lead slot is arranged, increases the distance between inlet wire and coil outer layer coiling, additionally it is possible to effectively
The contact between inlet wire and coil-winding is isolated in ground, reduces mechanical friction, reduces risk for mechanical damage.
In short, the coil block structure of the present invention can effectively improve the reliability of coil block, and it can improve and adopt
With the manufacture qualification rate of the product of coil block.
