Description

[Detailed Description of the Invention] The present invention relates to a multi-tube relay connector that connects a large number of flexible tubes.

In multi-tube relay connectors, it is necessary to insert soft tubes made of resin or the like into the hose nipples of the connecting tubes of the male connector and female connector. Changes in this result in variations in the insertion force of the tube, and especially when the hole diameter is small or the tube itself is hard, the insertion force increases and makes the insertion work difficult.

In order to facilitate the insertion of such tubes, the present invention provides tapered diameter expanding rods for expanding the inner diameter of the ends of the tubes at the tips of the screws protruding from the clamp discs of the male and female connectors. As a result, the inner diameter of the end of the tube can be expanded very easily without the need for special tools.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. As shown in FIG. 1 in a connected state and FIG. It is composed of a male connector 1 and a female connector 2.

The male connector 1 has a pair of joining plates 3a and 3.
It is equipped with a base plate 3 on which the base plate b is heavily fixed, and a clamp plate 4 mounted on the base plate so as to be able to come into contact with and separate from the base plate 3.
As can be seen from the figure and FIG. 4, a large number of male connecting pipes 5, 5, .
b is fastened with the fixing screws 6, 6, and the clamping steps of the male connecting pipes 5, 5, ... are clamped and fixed between them, and the plug pipe part 5a of the male connecting pipe 5 is connected to the female connector 2. At the same time, the hose nipple portion 5b is made to protrude to the opposite side, and a tapered portion 5e into which the tube 7 is inserted is formed in the hose nipple portion 5b. The clamp board 4 also has a recess 4a for accommodating the base 3 and guiding its sliding movement.
and the hose nipples 5b, 5.
b, ... and tubes 7, 7, ... fitted therein.
Clamp holes 4b, 4b, . . . are bored through which the . . . are inserted. The head 9a of the screw 9 for tightening is rotatably arranged between the joint plates 3a and 3b in a non-removal state, and the driver hole 9b of the head 9a is inserted through the through hole of the joint plate 3a. to expose the screw 9 to the outside.
is screwed into the clamp board 4 through the through hole of the joint plate 3b, and the tip of the screw 9 protruding from the clamp board 4 is equipped with a tapered diameter expanding rod 11a for expanding the inner diameter of the end of the tube 7. Nut 11 is screwed on. Therefore, by rotating the tightening screw 9, the base plate 3 and the clamp plate 4 can be moved closer to each other or separated from each other as shown in FIGS. …
The tubes 7, 7 fitted into the clamp holes 4b,
4b, . . . and the tapered portion 5c of the hose nipple portion 5b, each tube is firmly clamped at once.

On the other hand, like the male connector 1, the female connector 2 includes a base 13 to which a pair of joint plates 13a, 13b are fixed, and a clamp board 14 installed thereon, and a fixing screw 16, which fixes the pair of joint plates 13a, 13b. 16 to clamp and fix the clamping stepped portions of the female connecting pipes 15, 15, . The hose nipple part 15b is installed opposite to the hole bored in the joint plate 13a on the joint surface side with the male connector 1.
3b and protrudes to the opposite side through which the tube 7 is inserted into the hose nipple portion 15b.
It forms c.

Furthermore, the clamp board 14 is formed with a recess 14a for accommodating the base 13 and guiding its sliding, and the hose nipple parts 15b, 15b,
. . . and clamp holes 14b, 14b, . . . through which the tubes 7, 7, . The base plate 13 is provided with a tightening screw 19 similar to that of the male connector, which is screwed into the clamp disc 14, and the tip of the screw 19 protruding from the clamp disc 14 is provided with a tapered diameter expanding rod 21a. A retaining nut 21 is screwed on.

The above-mentioned male connector 1 and female connector 2 are joined by screwing the joining ring 12 rotatably attached around the clamp disc 4 of the male connector 1 to the outer periphery of the clamp disc 14 of the female connector 2. However, any fastening means for fastening both the clamp plates 4 and 14 and joining the joint surfaces of the bases 3 and 13 to each other can be employed.

In order to connect tubes together using a connector having such a configuration, first, as shown in FIG. 2, the male connector 1 and the female connector 2 are separated, and the base 3, 13
The clamp discs 4 and 14 are separated from each other to widen the gap between the tapered parts 5c and 15c of the hose nipple parts 5b and 15b and the clamp holes 4b and 14b, and in this state, the hoses 7 and 7 are inserted into the hose nipple parts 5b and 15b. wear. At this time, it may be difficult to insert the tubes 7, 7 due to variations in the inner diameter of the tubes 7, 7 made of synthetic resin or a decrease in hardness due to temperature changes. It is only necessary to once expand the inner diameter of the part with the tapered diameter expanding rods 11a, 21a protruding from the clamp discs 4, 14, and then insert it into the hose nut pull parts 5b, 15b, and this work can be done without preparing any separate tools. This can be done extremely easily and quickly with a small amount of force. After that, by rotating the screws 9 and 19, the bases 3 and 13 and the clamp plates 4 and 14 are fastened together.
Tapered portion 5c of hose nipple portion 5b, 15b,
15c and the inner edges of the clamp holes 4b and 14b clamp the tube.

Thereafter, by positioning the male and female connectors 1 and 2 using appropriate guides, joining the joining plates 3a and 13a to each other, and screwing the joining ring 12, the male and female connecting pipes of the male connector 1 and the female connector 2 are connected. 5 and 15 are connected to each other, and the tubes fitted therein communicate with each other.

The above tube is attached to the hose nipple part 5b, 15b.
To remove the tube, separate the male and female connectors 1 and 2 as shown in Figure 2, separate the bases 3 and 13 from the clamp plates 4 and 14 using screws 9 and 19, and pull the tube in this state. Bye.

As described above, according to the multi-tube relay connector of the present invention, the tips of the screws that connect the base and the clamp board in the male and female connectors to and from each other are made to protrude from the clamp board, and the inner diameter of the end of the tube is expanded at the tips. Since a diameter expanding rod is attached to the tube, the inner diameter of the end of the tube can be expanded without using a separate tool by press-fitting the tube into the diameter expanding rod before inserting the tube into the hose nipple. This makes it possible to easily and quickly insert the tube into the hose nipple with a small amount of force, and since the diameter expansion rod is located on the same side as the hose nipple, it is easy to expand the diameter of the tube and insert it into the hose nipple. Wearing can be done extremely easily as a series of movements.
