Description

clip

The present invention relates to a clip used for connecting a terminal portion of a shielding member having a planar shape provided to cover an outer surface of the fuel tank for protecting the fuel tank.

The outer surface of a fuel tank, such as an automobile, typically has a planar surface to protect the fuel tank, typically to protect the fuel tank from heat or to protect the fuel tank from physical shocks and collisions. It is not uncommon for the shielding member forming the above to be stuck.

FIG. 18 shows one typical method. In this method, the fuel tank T is wrapped with the shielding member I, and the end portions Ia thereof are bonded together so that the outer surface Ta of the fuel tank T is covered with the shielding member I.

Also, there is a type in which a clip member attached to a plate-shaped shielding member is fitted to a base member welded to the outer surface of the fuel tank so that the outer surface of the fuel tank is covered with the shielding member. (See Patent Document 1)

However, in the former method, it is necessary to apply the adhesive P, and since the connection of the terminal portion depends only on the adhesion, the connection state of the terminal portion is stable for a long time in consideration of the expansion of the fuel tank. Difficult to keep.

On the other hand, the latter method also requires welding of the base member to the fuel tank before the shielding member is attached.

JP 2007-331643 A

The main problem to be solved by the present invention is to make it possible to easily and stably maintain the state of the shielding member that is attached to the outside of this type of fuel tank.

In order to achieve the above object, according to the present invention, from the first aspect, the clip is a clip for connecting a terminal portion of a shielding member having a planar shape provided to cover the outer surface of the fuel tank. ,

By inserting the insertion protrusions of the first part into the connection through holes formed in the respective terminal portions of the shielding member to be connected, firstly, the shielding member that is attached to the outer surface of the fuel tank is adjacent. A terminal part can be connected in the state which prevented separation from the 1st member. Next, secondly, by engaging the engaging part of the second part with the first part between the terminal parts of the shielding member in this way, the terminal part is held in a sandwiched manner between the two parts, and the separation is performed. It is possible to stably maintain the blocking state by simply engaging both parts.

A temporary fixing portion is formed on the insertion convex portion of the first part, and in a state where the insertion of the shielding member into the connecting through hole is finished, is hooked to a hole edge located on the outer surface side of the shielding member in the connecting through hole. If this is done, the state in which the insertion protrusion of the first part placed on the outer surface of the fuel tank is inserted into the connecting through hole of the shielding member is the state before the second part is engaged with the first part. In this case, it can be temporarily maintained.

The insertion protrusion of the first part may be configured as a hollow body that receives the engagement part of the second part on the inside and is engaged with it. In this case, the first part and the second part can be engaged and combined in the connection through hole of the shielding member.

If the protrusion formed on the outer surface of the fuel tank is further accommodated in the base of the first part and a recess for positioning the first part is formed at the position where the protrusion is formed, the protrusion is By storing in the recess, the first part can be positioned at a predetermined position on the outer surface of the fuel tank prior to the covering of the shielding member.

The second part to be combined with.

According to this configuration, prior to the shielding member being attached to the outer surface of the fuel tank, the first part is provided at each end portion of the shielding member, and then the shielding member is covered with the outer surface of the fuel tank. The terminal part is held between both parts by hooking the hook part of the second part to the first part provided on each terminal part of the set shielding member from the state of being set outside Thus, the separation of the terminal portions can be prevented. Further, in such a clip, since the first parts provided in the connection through hole of the shielding member are separated from each other, regardless of the shape of the outer surface of the fuel tank, The seat portion can be easily brought into close contact with the outer surface of the fuel tank, and the covering state of the shielding member can be easily maintained by the clip.

A temporary fixing portion is formed on the insertion convex portion of the first part, and in a state where the insertion of the shielding member into the connecting through hole is finished, is hooked to a hole edge located on the outer surface side of the shielding member in the connecting through hole. By doing so, it is possible to maintain the state in which the insertion protrusion of the first part is inserted into the through hole for connection of the shielding member even in the state before the second part is engaged with the first part. .

According to this invention, the state of the shielding member that is stretched outside the fuel tank can be easily engaged by engaging the first part with the second part, and the insertion protrusion of the first part is penetrated for connecting the shielding member. It can be stably maintained by being inserted into the hole.

In addition, when there are a plurality of connection through holes Ib in the terminal portions Ia to be connected together, the second part M may be configured by providing the substrate 40 with a number of engagement portions 30 corresponding to this. .

In the example shown in the figure, the second part M is formed by providing an elongated plate-like substrate 40 with an engaging portion 30 having an axial shape protruding from one surface 40a of the substrate 40 in a direction perpendicular to the one surface 40a. . The hook portions 30 are formed at both ends of the substrate 40, and the distance between the two

hook portions

30, 30 is the distance between the connecting through holes Ib formed in the terminal portions Ia and Ia to be abutted. To be equal to That is, in the illustrated example, one hooking portion 30 of the second part M is hooked to the insertion portion 20 of the first part F provided on one of the terminal portions Ia with which the shielding member I is abutted, and the shielding member The other engaging part 30 of the second part M is engaged with the insertion part 20 of the first part F provided on the other end of the terminal part Ia to which I is abutted, and both parts F and M sandwich the shielding member I. Combined and the second part M prevents the terminal portion Ia from being separated.

In the example shown in the figure, each of the engaging

portions

30 and 30 includes a head portion 30a, a neck portion 30b, and a trunk portion 30c. The head 30a is configured to have a frustoconical shape with the top of the head being the smaller diameter side. The body portion 30c has one end integrally joined to one surface of the substrate 40, and has rib-shaped portions 30d along the axial direction on both sides in the diameter direction. The neck portion 30b connects the head portion 30a and the other end of the trunk portion 30c. Both parts F with the shielding member I sandwiched between the insertion part 20 of the first part F in which the insertion part 20 is inserted into the connection through hole Ib of the shielding member I and the insertion part 20 of the second part M being inserted. In the process of combining M, the head 30a is in contact with the protruding portion 20j constituting the hooked portion 20f of the insertion portion 20, and the elastic piece 20i constituting the hooked portion 20f is once bent outward, The protruding portion 20j is bent back at the position where it fits in the neck portion 30b, and the engaging portion 30 and the engaged portion 20f are engaged. In the example shown in the drawing, the flexure is smoothly generated by configuring the head 30a in a frustoconical shape.

According to the clip according to this embodiment, the first member F is provided on each terminal portion Ia of the shielding member I prior to the shielding member I being attached to the outer surface Ta of the fuel tank T. From the state in which I is set outside the fuel tank T so as to cover the outer surface Ta of the fuel tank T, the second part M is added to the first part F provided at each terminal portion Ia, Ia of the set shielding member I. By engaging the engaging portion 30, the terminal portion Ia can be held in a sandwiched manner between the parts F and M, and separation of each terminal portion Ia can be prevented. Further, in such a clip, since the first parts F provided in the connection through hole Ib of the shielding member I are separated from each other, regardless of the shape of the outer surface Ta of the fuel tank T, The seat part 10 of each first part F can be easily brought into close contact with the outer surface Ta of the fuel tank T, and the covering state of the shielding member I can be easily maintained by the clip. For example, even when the outer surface Ta is curved so that the outer surface Ta of the fuel tank T protrudes to the outermost side at the portion where the terminal portion Ia of the shielding member I is abutted, the terminal portion Ia is abutted. The seat portion 10 of the first part F can be brought into close contact with the outer surface Ta of the fuel tank T on both sides of the location, and the second part M follows the curve of the fuel tank T in some cases outside this. It engages with each 1st part F, producing | generating bending, and the space | interval between each 1st part F and F, ie, the space | interval between the terminal parts Ia of the shielding member I, is prevented.

In this embodiment, in particular, the insertion part 20 of the first part F is configured as a hollow body that receives and engages with the engaging part 30 of the second part M on the inside, so that the shielding member The first part F and the second part M can be engaged and combined in the through hole Ib for connection I.

In addition, the provision of this characteristic to the part which should be provided with the elastic deformation characteristic in the clip demonstrated above is easily ensured by making said 1st part F and 2nd part M into the injection molding goods made from a synthetic resin. be able to.
