Description

[Detailed description of the invention] The present invention combines a plug-shaped frame holding member made of a synthetic resin product that holds a frame rod, a guide sleeve made of a metal material, and a fitting body of the frame holding member. The present invention relates to an improvement in the frame holding member of a plug which is assembled by fitting into the proximal end lumen of a guide sleeve.

An object of the present invention is to form the above-mentioned frame holding member so that it can be firmly fitted into the guide sleeve in a simple process.

To explain the drawing in detail, the above-mentioned plug A is
As shown in Fig. 1, frame bars 1, 1, and
The base end of a guide sleeve 3 made of a metal material is fitted and connected in an outer cylinder shape to a frame holding member 2 made of a synthetic resin material that holds... As shown in FIG. 2, each lead wire 41 drawn out from the cord 4 is adhered by soldering to the connection terminal portion of each frame rod 1 protruding from the outer end surface 21 of the frame holding member 2, and , as shown by the chain line in Fig. 2, is covered with a synthetic resin material so as to cover the connecting part, and the molded part 5 is held as a knob, and the guide sleeve 3 is used to connect it to the jack (not shown). Each frame rod 1 is inserted and projects into its guide sleeve 3
The tip of the jack is inserted into each socket of the jack for connection.

By the way, in this type of plug A, the connection between the frame holding member 2 and the guide sleeve 3 is loose, and as mentioned above, they often fall off during use. There is a problem in that it makes the process complicated.

Therefore, in the present invention, when molding the frame holding member 2 from a synthetic resin material, as shown in FIG.
When the guide sleeve 3 is press-fitted into the fitting body 22 from the inner end side, the base end surface 31 of the guide sleeve 3 is made to abut against the inner surface of the flange 21, and the formed flange 21 A fitting recess 6 is formed in a part of the peripheral edge of the fitting body 22, and as shown in FIG. This proposes a means for forming a groove in the axial direction across the fitting body portion 22.

In this way, if the frame holding member 2 molded into a plug shape for holding the frame rod 1 is formed from a synthetic resin material, the fitting body portion 22 of this frame holding member 2 can be connected to the guide sleeve 3 made of a metal material. When assembling the plug A into the plug A by press-fitting it into the proximal end lumen of the guide sleeve 3 and connecting it with the guide sleeve 3,
Fitting of the fitting trunk 22 of the frame holding member 2 into the guide sleeve 31 is stopped when the base end surface 31 of the guide sleeve 3 abuts against the inner end surface of the annular flange 21 provided at the end of the frame holding member 2. This flange 21
This means that the fitting body 22 of the frame holding member 2 can be strongly press-fitted into the inner cavity of the proximal end of the guide sleeve 3 until the end surface 31 on the proximal side abuts against each other, making this fitting operation easy. And it can be done powerfully.

Then, after the fitting trunk 22 of the frame holding member 2 and the guide sleeve 3 are fitted together, the guide sleeve 3 is
At a portion corresponding to the fitting recess 6 provided on the circumferential surface of the frame holding member 2, a portion 33 located on the distal side of the position 32 corresponding to the terminal surface 61 of the fitting recess 6 is strongly pressed into the fitting recess by pressing or the like. By pushing the guide sleeve 3 toward the inside of the fitting recess 6 and not biting into the fitting recess 6, the guide sleeve 3 that fits on the outer periphery of the frame holding member 2 is inserted into the fitting recess 6 in the circumferential direction. In addition, in the axial direction, the proximal end surface of the guide sleeve 3 abuts against the annular flange 21 and the pushed-in portion of the guide sleeve 3 (corresponding to the fitting recess 6) is fixed. Part 3
3) and the end surface 61 of the fitting recess 6, it is fixed in both the inner end side (distal end side) and outer end side (base end side).

In this case, when the proximal end of the guide sleeve 3 is fitted into the fitting body portion 22 of the frame holding member 2 so that the proximal end surface 31 abuts the inner surface of the flange 21, the guide sleeve 3 is provided with the fitting recess. By forming an appropriate thin-walled portion 7 in the portion facing the distal end side from the portion 32 corresponding to the end surface 61 of the frame holding member 2, the frame holding member 2 can be fitted into the fitting body portion 22 of the frame holding member 2 as described above. ,
When the portion 33 corresponding to the fitting recess 6 is strongly pressed by a press or the like, the portion 33 is separated from the joint portion with the thin wall portion 7 as shown in FIGS. 7 and 8, and the end surface 61 The frame holding member 2 in the plug according to the present invention is a guide sleeve made of a metal material. The flange 21 can be press-fitted into the inner cavity on the proximal end side of the guide sleeve 2 to make the process of press-fitting it extremely easy, and to facilitate the connection with the guide sleeve 2 after the press-fitting. The fitting recess 6 that receives the guide sleeve 2 to be pushed in and the end surface 61 thereof make it possible to firmly prevent movement in the circumferential direction and the axial direction.
