Abstract
The invention provides a terminal fixing structure capable of surely preventing detachment of a terminal and making the structure compact. A projection 3h engaged with an engagement hole 6a formed to a terminal 6 is arranged on one face of terminal insertion holes 3f, 3g for inserting the terminal 6, and an induction wall 3i for inducing the terminal 6 toward the projection 3h is installed on the opposed face of the projection 3h. Therefore, the engagement hole 6a formed to the terminal 6 and the projection 3h are surely engaged with each other, to prevent detachment of the terminal 6. The periphery of the terminal is made compact, and a delivery pipe can be miniaturized.
Description
Technical field
The present invention relates to a kind of delivery pipe of two-wheel vehicle fuel injection system, in detail, the present invention relates to a kind of structure that is used for fixing joint component, this joint component and delivery pipe integrally are assemblied in the delivery pipe.
Background technique
Recently owing to the emission control of having strengthened two-wheel vehicle, increased the use of two-wheel vehicle fuel injection system, the fuel injection system miniaturization becomes indispensable.The compact structure that is used for fuel being provided and being used for nozzle is fixed on the delivery pipe of intake manifold to nozzle is very important.In the joint component fastening structure of prior art, general method is to make bunch be riveted on the joint component and using under the state of waterproof sealing member covering, insertion is arranged in the joint patchhole 23a on the housing 23 of delivery pipe shown in Figure 4 22, and make the jut 23c engagement, fixing of the snap-fastener engaging hole that is arranged at not shown joint component one side and snap-fastener engaging piece 23b, wherein snap-fastener engaging piece 23b is arranged on housing 23 1 sides for preventing to extract.
Yet, as shown in Figure 4, on housing 23, form the assembly structure of snap-in form, therefore has a space segment 23d in 23b inboard, snap-in joining portion, allow described snap-in joining portion 23b resiliently deformable, therefore, the joint insertion portion needs unnecessary volume, thereby has hindered the compactness that realizes the joint component fastening structure.
Summary of the invention
The purpose of this invention is to provide a kind of joint component fastening structure, can realize the compactness of this structure, prevent that joint component from coming off.
In order to realize purpose of the present invention, in first kind of formation of the present invention, a kind of fastening structure of joint component of delivery pipe is provided, described delivery pipe make by synthetic resin and with joint component be one, described delivery pipe is used for nozzle is fastened on intake manifold, simultaneously provide fuel to nozzle, described fastening structure comprises: be arranged on the face of the joint patchhole that is used to insert described joint component and the protruding part front end sidepiece engagement of being located at described joint component; The opposite that is arranged on described protruding part is used for described joint component is directed to the guide surface of described protruding part one side.
In second kind of formation of the present invention, described joint patchhole is set on the housing of delivery pipe, looks along the side direction of described joint patchhole, and the relative central axis with described guide surface of described protruding part toward each other.
Because the present invention has said structure, can be achieved as follows effect.That is to say, owing on the hole wall of the joint patchhole of joint component insertion portion, a protruding part is set, joint component front end sidepiece and the engagement of this protruding part, one guide surface is set on the hole wall of joint patchhole, this guide surface is in the face of described protruding part and guide described joint component to tend to described protruding part, be arranged on engaging hole and the engagement of this protruding part on the joint component, can hinder joint component and come off.In addition can compactness around the structure of joint component, also can reduce the size of delivery pipe.
Description of drawings
Fig. 1 has shown vertical sectional view of the delivery pipe assembly of one embodiment of the invention;
Fig. 2 is the right side view of Fig. 1;
Fig. 3 is the sectional view that amplify the part of joint component insertion portion shown in Figure 1;
Fig. 4 has shown the sectional view that amplify the part of the joint component insertion portion of prior art.
Embodiment
Hereinafter will introduce most preferred embodiment of the present invention in conjunction with the accompanying drawings.In Fig. 1～3, delivery pipe assembly 1 comprises the delivery pipe of being made by synthetic resin 2, and delivery pipe 2 comprises housing 3, at the middle body of housing 3 a fuel passage 3a is set.The side of fuel passage 3a (left side of Fig. 1), the patchhole 3b of formation nozzle 4.At the opposite side (right side of Fig. 1) of fuel passage 3a, form a fuel inlet that communicates with tracheal portion 3c shown in Figure 2.The whole flange portion 3d that forms forms mounting hole 3e on the housing 3 on this flange portion 3d, utilizes the bolt (not shown) that inserts this mounting hole 3e, and delivery pipe assembly 1 is fastened among the figure on the target intake manifold.
In addition, on housing 3, be provided with the joint patchhole 3f and the 3g of the parallel axes of two axis and patchhole 3b.These two patchhole 3f and 3g have constituted the insertion portion of joint component respectively.On the face of each patchhole 3f and 3g, form protruding part 3h, and on opposing side, form guide surface 3i.Look on (right side of Fig. 3) from the side of patchhole 3f or 3g, protruding part 3h and guide surface 3i are formed on respectively with respect to central axis position respect to one another.Power line 5 is fixed on the joint 6, and joint 6 and sealing component 7 are inserted in nipple orifice 3f and the 3g together.At joint 6 ends an engaging hole is set.The sidepiece 6a of described end and protruding part 3h engagement are moved to stop joint 6.Sealing component 7 adopts the air tight manner press contacts with power line 5 and joint patchhole 3f, 3g, thereby keeps waterproofing effect.
Hereinafter will introduce the operation of present embodiment.When inserting the joint 6 that is fastened with power line 5 and sealing component 7 in joint patchhole 3f, the 3g, the front end of joint 6 moves along guide surface 3i.When joint 6 was inserted into joint patchhole 3f, 3g terminal, by guide surface 3i, joint 6 was directed into protruding part 3h, and front end sidepiece 6a and protruding part 3h engagement stop joint component 6 to be pulled out.In addition, snap-fastener mate 23b (with reference to figure 4) volume inside part 23d (with reference to figure 4) is set not needing to resemble in the prior art, therefore can reduces the volume of joint insertion portion, so the structure of delivery pipe 2 can be compact more.
The fuel that is pressed to the tracheal portion 3c of delivery pipe 2 arrives spray chamber 4d through the fuel channel 4c that is set at nozzle 4 middle parts.When by power line 5, joint 6 and power connection 4a when nozzle 4 provides electric energy, valve 4e is unlocked, and fuel is sprayed in the intake manifold (not shown) from jetburner 4f.As shown in phantom in Figure 2, the direction that is provided with of conduit 3c can be arbitrarily, and therefore, fuel can be imported into from any direction.
