Field of the Invention The present invention relates to a joint structure having an article and a joint for attaching the article to the joined body. [Prior Art] Up to now, articles such as connectors have been mounted on electronic devices and the like. In this case, for example, a screw is used as the coupling member. However, for maintenance inspections and replacements, it may be necessary to remove the screws from the electronic equipment. At this time, even if the screw is loosened, if the screw does not fall off the connector, the work efficiency can be improved and the screw can not be lost. Here, for example, there has been a proposal for a combined structure as shown below. In the first joint structure, as shown in FIG. 6A, a sleeve 72 made of synthetic resin is interposed between the screw 73 and the insertion hole 71A on the article 71 into which the screw 73 is inserted (for example, reference) Unexamined Japanese Patent Publication No. 5-89938). Specifically, the shaft portion of the screw 73 has a thread formed over its entire length. In the case of the sleeve 72, it is cylindrical and the shaft portion of the screw is inserted. The sleeve 72 has an outer diameter slightly larger than the inner diameter of the insertion hole 71A. On the rear end side of the inner peripheral surface of the sleeve 72, a plurality of projections 72A for engaging the screw shaft portions are formed at equal angular intervals. According to the first joint structure described above, the sleeve 72 is pressed into the insertion hole 71A, and the screw 73 is further pressed into the sleeve 72 so that the projection 72A engages the screw". Thereby, the screw 73 can be prevented from coming off. In terms of construction, as shown in Fig. 6B, a plurality of hemispherical projections 81B are provided on the jack 81 of the article 81 for inserting the screw. 92845.doc 1294950 Specifically, the shaft portion of the screw 8 3 The threaded portion 83A is formed with a threaded portion and the non-threaded portion 83B is formed without a thread. The outer diameter of the non-threaded portion mb is slightly smaller than the diameter of the root circle of the threaded portion 83 A. The protruding portion 81B is as shown in Fig. 6C. As shown, it is provided on the inner peripheral surface of the insertion hole 81A at four equal intervals. The interval between the mutually facing projections 81B is slightly larger than the diameter of the gear root of the screw portion 83 A. In the second coupling structure, the screw 83 is pressed into the insertion hole 81A so that the screw portion 83A of the screw 83 is located at the front end of the projection portion 81B of the insertion hole 81a. Thereby, the screw 83 will remain in a loose fit state even if The screw "will fall off because the protrusion 81B will lock the threaded portion 83 of the screw 83, because This prevents the screw 83 from coming off. In the third joint construction, as shown in Fig. 6D, it is provided with a rubber ring 92 at the front end of the screw 93. Specifically, the article 91 is formed with an insertion hole 91A for screw insertion. The shaft portion of the screw 93 includes a threaded portion 93a formed with a thread and a non-threaded portion 93 which is not formed with a thread. The outer diameter of the non-threaded portion 93B is smaller than the diameter of the root circle of the threaded portion 93A. A rubber ring 92 is attached to a portion having a height difference between the screw portion 93a and the non-thread portion 93b. According to the third combined structure described above, the screw 93 is pressed into the insertion hole 91A so that the threaded portion of the screw 93 is exposed by the front end of the insertion hole 91A. Next, the rubber ring 92 is attached to the exposed portion of the screw 93. Thereby, even if the screw is removed, the rubber will lock the dragon 91A, thereby preventing the screw from falling off. However, according to the first combined structure described above, the sleeve 72 must be separately prepared, so that the number of parts is increased, making assembly complicated. 92845.doc Ι294#5βΐ2567 Patent Application "/Γ一~~ Chinese Manual Replacement Page (January 1996)丨_ , :/ ^ —.d-wm:.:卞·~..v. ,. In addition, in the third joint structure, the rubber ring 92 must be separately prepared. Therefore, as with the first joint structure, the number of parts is increased, making assembly complicated. Further, in the second joint structure described above, When the screw 83 is pressed into the insertion hole "A", the threaded portion 83A is caused to break the front end of the projection (10). Further, in the case where the projection 81B is integrally molded with the synthetic resin in the insertion hole 81A, there is a possibility that the molten resin cannot sufficiently fill the projection _.

A countersunk hole is formed on the rear side of the jack. The coupling structure 10 further includes a waterproof gasket 4 for inserting the shaft portion 21 to seal the shaft portion to the gap with the insertion hole 11. Fig. 5 is a cross-sectional view showing the state in which the waterproof connector 5 is placed on a flat surface. Fig. 0 The waterproof connector 5 is removed from the drive terminal of the servo motor and placed on the table. The fixing screw 2 is in a state of being protruded upward. Here, the distance L1 from the pair of projections and (7) to the bottom surface of the waterproof connector 5 is longer than the length of the joint portion 2 of the shaft portion 21. Therefore, for example, when the waterproof connector 5 is placed on a flat surface, although the insertion hole u is sealed, the 'joining portion 2A does not protrude from the insertion hole u'. Therefore, waterproofing can be prevented, and the connector 5 can be prevented. The front end and a pair of protrusions 丨8 and 1B are damaged. · The above-mentioned waterproof connector 5 can provide a suitable combination of waterproof type. In addition, the waterproof loop and the flat washer can be prevented from falling off. In addition, since the nominal diameter of the joint member is set to the flat head screw of (10) to M3, it is easy to find when it is detached, and is particularly useful for small electronic equipment. · According to the combination structure of the present invention, the following effects can be obtained. By inserting the coupling member into the insertion hole, the non-joining portion of the coupling member is subjected to rotation, Ό, δ. The snail is screwed to the protrusion. When the coupling member is further rotated, the coupling member is moved to the front end side of the insertion opening so that the joint portion faces the projection. As a result, the joint member will remain in a loose fit state, and even if the joint member is to be detached, the protrusion will lock the joint portion and thus will not fall off. In addition, since no additional parts are required, the combined structure can form 92845-961019.doc -14-1294950 Simple structure β [Schematic description of the drawings] Fig. 1 is a combination of the embodiments of the present invention.
