Specific embodiment
Core of the present utility model is to provide a kind of magnetic assembly of shift fork, simplifies the structure of the housing of magnet assemblies,
Improve plastic quality, it is to avoid produce unnecessary technological deficiency, and the structure of simplified connector on this basis, improve buckle
Reliability.
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool
The utility model is described in further detail for body embodiment.
It should be noted that the herein presented noun of locality " top " refers to left upper end in Fig. 2, " bottom " refers to figure
Bottom righthand side in 2；It should be appreciated that these nouns of locality are set up on the basis of Figure of description, their appearance should not be right
Protection domain of the present utility model is construed as limiting.
Fig. 2 is refer to, Fig. 2 is provided a kind of structure of specific embodiment of the magnetic assembly of shift fork by this utility model
Schematic diagram.
In a kind of specific embodiment, as shown in Fig. 2 this utility model provides a kind of magnetic assembly of shift fork, including
Magnet assemblies 1 and the connector 2 for the magnet assemblies 1 to be connected with shift fork, the magnet assemblies 1 include plastic housing
11 and plastic housing 11 be encapsulated in the Magnet 12 of one.The plastic housing 11 includes the installation portion 111 on top and the cylinder of bottom
Body, the Magnet 12 is connected with the installation portion 111, and the bottom of the cylinder 112 is provided with the opening for installing the connector 2
112a, and the side wall of the cylinder 112 is provided with installing hole 112b, the side wall of the connector 2 is provided with lobe 21, described convex
Play portion 21 and form clamping with the installing hole 112b.
Using this structure, to during the inserting of cylinder 112, during into opening 112a, cylinder 112 is connected connector 2
Dilatating and deformable is omited in the both sides that are pressed against of the lobe 21 of fitting 2, and connector 2 continues inwardly motion, when lobe 21 moves to peace
During the position of dress hole 112b, lobe 21 reaches installing hole 112b outsides, forms clamping, while cylinder 112 shrinks, recovers former
Shape.Also, stretching out in the lobe 21 of installing hole 112b both sides can avoid connector 2 from outwards scurrying out by opening 112a, protect
The reliability of interface arrangment is demonstrate,proved.
As can be seen here, the card of connector 2 and housing 11 is simply, easily realized using lobe 21 and installing hole 112b
Connect, compared with structure of the prior art, without the need for arranging Elastic buckle, guiding surface, will not be due to buckle in installation process
Connector 2 is sharply damaged, the generation of burr is it also avoid.Additionally, the plastic housing 11 only includes installation portion 111 and cylinder
112, and only need to open up the i.e. achievable clampings with connector 2 of installing hole 112b in cylinder 112 so that the entirety of plastic housing 11
Simple structure, processing, manufacturing cost are less.If additionally, see that lobe 21 is stretched out in outside installing hole 112b in installation process,
Can exactly judge that the clamping assembled is formed so that assembling quality Identification degree is higher.
The concrete shape of lobe 21 is further set with reference to Fig. 3, Fig. 3 is that the plane of connector 2 in Fig. 2 is illustrated
Figure.
In a kind of specific scheme, above-mentioned lobe 21 is with the first side wall 211 near the cylinder 112, away from institute
State between the side wall of the second sidewall 212 of cylinder 112, the first side wall 211 and the connector 2 at the top of it in the first folder
Angle A, first included angle A is obtuse angle.
Using this structure, the gradient of the first side wall 211 of lobe 21 is less, in installation process, the first side wall 211 with
The bottom of cylinder 112 contacts, and the less gradient plays a part of guiding, is easy to connector 2 smoothly to enter inside cylinder 112.
In another kind of specific scheme, in the between the side wall of the connector 2 of above-mentioned second sidewall 212 and its bottom
Two included angle Bs, the second included angle B is acute angle or right angle.
So, the gradient of second sidewall 212 is larger.When connector 2 moves to the correspondence position of installing hole 112b, second
Side wall 212 coordinates with the bottom of installing hole 112b, and the larger gradient can avoid lobe 21 from deviating from from installing hole 112b,
Strengthen the stability of the two clamping.
Additionally, at least one of the first side wall 211, described second sidewall 212 are plane or smooth surface.
In further scheme, above-mentioned connector 2 is additionally provided with the groove 22 for caving inward in the bottom of the lobe 21.
The groove 22 enough further enhances the clamping reliability of connector 2 and cylinder 112, it is to avoid the Jing of connector 2 is open
112a outwards scurries out.
It is contemplated that above-mentioned connector 2 and not only limit avoids connector 2 from outwards scurrying out by groove 22, can also will be convex
The root for playing the bottom of portion 21 arranges chamfering, can equally play the technique effect for preventing from outwards scurrying out.The chamfering can be specially side
Chamfering or rounded corner.
In another kind of specific embodiment, as shown in Figure 2 and Figure 3, above-mentioned connector 2 can be integral type structure.
The connector 2 of integral structure has the advantages that compact conformation, with the company that prior art includes two connectors 2
Connected components are compared, and structure is simplified, simplified number of parts, it is to avoid the complicated technology that system redundancy brings, and are reduced
The production cost of the magnetic assembly of shift fork.
The shape of above-mentioned integral type connector 2 can be with varied.
For example shown in Fig. 2, the cross section of above-mentioned integral type connector 2 can be rectangle.Certainly, the shape of the connector 2
It is not limited to that, the various shapes such as circle, ellipse can also be set to.In order to ensure the cylinder 112 of plasticity housing 11
With the clamping stability of connector 2, cylinder 112 can be shaped to identical with the shape of connector 2.
Further, it is also possible to further arrange the concrete structure of Magnet 12.
As shown in Fig. 2 the Magnet 12 can be integral type structure.
It is contemplated that Magnet 12 can also be set to into other structures.For example, as shown in figure 4, Fig. 4 is this utility model
The structural representation of another kind of specific embodiment of provided magnet assemblies 1.The Magnet 12 is split-type structural, including at least
Two points of Magnet 121.Specifically, the quantity for being divided to Magnet 121 can be two, three, even more many.
A kind of magnetic assembly of shift fork provided by the utility model is described in detail above.It is used herein
Specific case is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help
Understand method of the present utility model and its core concept.It should be pointed out that for those skilled in the art,
On the premise of without departing from this utility model principle, some improvement and modification can also be carried out to this utility model, these improve and
Modification is also fallen in this utility model scope of the claims.
