Description

[Detailed description of the invention] This invention uses cable ties to tie pipes installed in the engine room of automobiles or cords installed inside electrical equipment to panels that serve as the base of these equipment. This invention relates to a fastener for cable ties that can be fixed in a tied state.In particular, this invention not only fixes the cable ties integrally to the panel, but also fixes the bands themselves to bind objects such as pipes and cords. To provide a fastener for a binding band which can be tied in a tied or tightened state and can fix the band to a panel and bind and tighten the band itself at the same time.

Many fasteners, particularly plastic fasteners, for fastening pipes and cords to panels have already been proposed and put into practical use.

Some of these binding bands are used simply to bundle a plurality of cords, but some are known that are equipped with a fixing means for binding the bundled cords and fixing the bundled cords to a panel or the like.

A conventionally known binding band equipped with this kind of fixing means, as disclosed in Japanese Utility Model Application Publication No. 54-69385, has a buckle at the end of the band, and the other end is inserted into the buckle, thereby forming a loop. While the cords are held inside the buckle, the buckle is generally fitted with a locking leg that fits into a hole drilled in the panel to secure the held cords to the panel. It is.

As mentioned above, this conventional binding band has a wide range of uses in that the band itself is equipped with a self-binding means such as a buckle and a fixing means to the panel, but the squaring means and the fixing means are simply co-located. There is no functional relationship between the two, therefore they must be operated separately, and they are fixed to the panel only by engaging the engaging legs, so there is a lack of material strength. In some ways, it was not possible to expect a firm fixation.

In view of these points, the present invention makes the engaging leg, which is a fixing means attached to the buckle, completely independent of the cable tie and makes it a single fastener, thereby increasing the locking force against the panel and increasing the fastening force. It is an object of the present invention to provide a fastener for a binding band, which is characterized in that the tool has a function as a buckle as described in item 7 above, and the band can be simultaneously fixed to a panel and tied together.

Hereinafter, an embodiment illustrating the present invention will be described. In the figure, reference numeral A indicates a fastener according to the present invention, B indicates a binding band, and C indicates an engine room, etc., in which this band is fastened via the above-mentioned fastener. The panel that is the base of the is shown.

The fastener A has a rectangular cylindrical insertion section 1 as its center, and a collar section 2 extending from the outer peripheral surface of the upper end of the insertion section, and a collar section 2 that is provided so as to face the aforementioned collar section from the outer peripheral surface of the insertion section. A locking claw 3 as a locking means and a restraining part 5 as a restraining means for restraining the band B extending from the lower end of the insertion part and inserted through the hollow part 4 of the insertion part in a tied state are made of thermoplastic synthetic resin. This fastener is made by inserting the insertion part 1 into a pre-drilled hole C' in the panel C, bringing the flange 2 into contact with one side of the panel, and pressing the flange 2 against the outer peripheral surface. It is fixed to the panel by passing the locking claw 3 protruding from the through hole C' and locking it to the other side of the panel.

In order to securely secure this fixation, elastic contact pieces 6, 6 are provided extending from the edge of the flange portion 2 diagonally downward toward the insertion portion 1 side. is brought into contact with one side of the panel and cooperates with the locking pawl 3 to elastically clamp and fix the panel.

The locking piece 3 has a U-shaped cutout in the cylindrical wall surface of the insertion section 1 and is raised up so as to face the collar 2, and when inserted into the through hole C' of the insertion section, it must first be inserted into the insertion section. It is flexed to allow its passage, and after passing, it can be restored and locked on the opposite side of the panel.

On the other hand, in this embodiment, the restraining part 5 extending from the lower end of the insertion part 1 has a cylindrical shape with a rectangular cross section, and its inside communicates with the hollow part 4 of the insertion part. Both ends of the band B to be inserted are overlapped so that the band B can be passed through the band B.

The fastener of the present invention constructed in this way is fixed to the through hole C' of the panel C as described above, while the fastener of the present invention is fixed to the through hole C' of the panel C as described above. Align the two ends so that they are overlapped, pass it through the hollow part 4 from one (upper) opening of the insertion part 1, and then pull it out through the inside of the restraint part 5 to the opposite side of the panel, and then use an appropriate tool such as a punch to pass it through the hollow part 4. This band is restrained and fixed to the panel by crushing the cylindrical wall surface of the restraining part 5 into a punched shape and tightening it.

In this case, the band inserted into the hollow part 4 of the insertion part is fixed at both ends by the restraining part 5, thereby being restrained in a loop shape, so that the object to be bound is contained within this roof and fixed to the panel. Although this may be true, if both ends of the band C that has slipped out of the restraint part 5 are tightened during the above-mentioned fixing, and the object to be bound in the loop is tightened and dried, the object to be bound will be tightened and the panel will tighten. can be fastened to.

In addition, the reference numeral 7 shown in the drawing is a protrusion protruding from the upper surface of the flange part 2 in such a way as to sandwich the opening of the hollow part 4, and as mentioned above, this protrusion tightens both ends of the band to tighten the loop. When the loop receives the lower surface of an object to be bound, such as a pipe, it rebounds due to the elasticity of the material, and functions to hold the object more securely.

The fastener of the present invention is constructed and used as described above, and as described above, fastening to the panel is performed by simply pushing the insertion part 1 into the through hole C', and the band B is attached. Both ends of the object wrapped around the object and bent into a loop are passed through the hollow part 4 of the insertion part and then crimped at the binding part, so the work is easy and at the same time The fastener can be fixed to the panel in a tight state by squeezing both ends of the band that has come out of the hollow part of the insertion part and restraining it in that state, and has the feature of being able to be firmly fixed. This is particularly advantageous when pipes and the like installed in the engine compartment of an automobile are fixed to a base panel.

In addition, when using the fastener of the present invention, in the above embodiment, the fastener is fastened to the panel, and then the band is inserted and restrained. Of course, it is also possible to insert the fastener into the hollow part of the fastener and restrain it, then insert the insertion part of the fastener into the through hole of the panel, and then use the locking claw to engage and secure the fastener. The method of use may be arbitrarily selected depending on the application.

By the way, although the fastener shown in the above embodiment is designed for a flat band-shaped band, for example, when using a band with continuous wave-shaped unevenness on the surface of the band, A check-type claw is provided protruding from the inner wall surface of the cylindrical restraint part 5 or the inner wall surface of the hollow part of the insertion part, and when tightening the band, the ends passed through the hollow part can be passed through the hollow part without going against the claws. When the band is made to be inserted and then pulled back, the claw may be engaged with one of the convex portions to restrain the band, and the band may be tightened and tied at the same time.

In short, the structure of the restraining part 5 in this fastener is selected depending on the band used, but if the band itself is in the shape of a flat strip, it should be shaped like a cylinder as in the above embodiment. After inserting it, caulk it with a punch,
A method of restraining the movement of the band by biting a part of the cylindrical wall into the band is easy and advantageous in view of the oval shape of the restraining portion and in terms of workability.

On the other hand, it is effective for the band used above to have a cross-sectional area similar to the cross-sectional area of the hollow part of the insertion part when both ends are aligned so as to overlap, in order to strengthen the fixation of the fastener to the panel. It is.

In other words, the insertion part that is inserted and locked into the through-hole of the panel inserts the overlapping band into the hollow part, and when in use, the inside is filled with the band and becomes solid, so even if a strong removal force is applied. Even if the insertion portion is bent inward, this will not significantly affect the supporting force of the engaging claws provided on the outer circumferential surface of the insertion portion. If the gap can be kept small when the insertion part is inserted, the insertion part will not bend at all due to the removal force, and therefore, the influence on the locking claw can be completely eliminated, so that the locking force applied to the locking claw can be completely eliminated. Since the locking force can be exerted as it is and the fixation to the panel can be ensured, the locking effect can be increased.
