【考案の詳細な説明】
本考案は熱可塑性樹脂からなる溶潰ピンを備え
た部材の結合装置に関し、結合しようとする部材
の仮結合ができるようにするとともに、溶潰ピン
による結合を確実にしようとするものである。[Detailed description of the invention] The present invention relates to a joining device for members equipped with a meltable pin made of thermoplastic resin, which enables temporary joining of the members to be joined, and ensures reliable joining by the meltable pin. This is what I am trying to do.
一般に熱可塑性の合成樹脂成型品を結合しよう
とするとき、前記合成樹脂成型品に溶潰ピンを一
体に設けておき、これを結合しようとする部材の
孔に挿入し、前記溶潰ピンの先端を加熱して潰ぶ
すことにより結合を行なうことが知られている。 Generally, when trying to join thermoplastic synthetic resin molded products, a melting pin is provided integrally with the synthetic resin molding, and this is inserted into the hole of the member to be joined, and the tip of the melting pin is inserted into the hole of the member to be joined. It is known that bonding can be achieved by heating and crushing.
ところでこれら結合しようとする部材をあらか
じめ仮結合させたい場合があり、単に溶潰ピンを
備えたものでは他に補助部材を用いなければ仮結
合ができないものであつた。 By the way, there are cases where it is desired to temporarily join these members to be joined in advance, and if the members are simply provided with a melting pin, temporary joining cannot be performed without using an additional auxiliary member.
本考案はこのような仮結合を可能にするととも
に、結合が確実な結合装置を提供しようとするも

に径が小さくなるテーパ孔となつている。 The melting pin 2 has a plurality of ribs 3 formed in the axial direction on the outer periphery. Furthermore, the rib 3 is
The diameter of the melting pin 2 including the rib 3 is tapered so that it gradually becomes smaller at the tip. Reference numeral 4 denotes a switch base to which the upper cover 1 is to be connected, which is made of thermosetting urea resin, and together with the upper cover 1 constitutes a switch housing. This switch base 4 has a melting pin insertion hole 5 into which the melting pin 2 of the upper lid 1 is inserted.
have. This melting pin insertion hole 5 is shorter than the length of the melting pin 2. Further, at least a portion of the diameter is larger than the diameter of the tip portion of the melting pin 2 including the ribs, and smaller than the diameter of the main portion of the melting pin 2. Further, the melting pin insertion hole 5 has a recessed step portion 6 having a diameter larger than the melting pin insertion hole 5 at the edge on the non-insertion side. Further, the melting pin insertion hole 5 is a tapered hole whose diameter becomes gradually smaller from the insertion side.

溶潰部分がうまり、その結合状態を安定にする。 The device for joining members equipped with melting pins of the present invention includes the two members configured as described above, and when joining them, first, as shown in FIG. Press fit into the melting pin insertion hole 5. At this time, since at least a portion of the diameter of the melting pin insertion hole 5 is smaller than the diameter of the main portion of the melting pin 2 including the rib, the rib 3 comes into pressure contact with the inner surface of the melting pin insertion hole 5. Since each rib 3 has a relatively small width and is made of a relatively soft material such as polypropylene, the pressure contact between the ribs 3 is good, and the upper cover 1 and the switch base 4 remain temporarily connected, while other parts This facilitates assembly work such as mounting. Next, when completely joining, the tip of the melting pin 2 protruding from the melting pin insertion hole 5 is crushed with a heating jig to complete the joining (see FIG. 3). At this time, the crushed portion of the melting pin 2 is pushed into the gap between each rib 3, ensuring a melted and fixed state. If a recessed step 6 is provided on the non-insertion side of the melting pin insertion hole 5 of the switch base 4, the melting portion of the melting pin 2 will fit into this portion as well, thereby stabilizing the bonded state. .

実用価値の大きいものである。 As described above, according to the present invention, by providing a rib on the melting pin, there are advantages such as stable temporary bonding of the parts to be bonded and a reliable bonded state. Since it has a simple structure, it is easy to manufacture and has great practical value.

の作用効果に差異を生じない。 In the embodiment, both the melting pin including the rib and the melting pin insertion hole each have a taper, but only one of them may have a taper. Further, although the switch case has been described, it may be used to connect other parts without causing any difference in the operation and effect of the connecting device of the present invention.
