Description

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

Conventionally, a relay connector as shown in FIG. 1 has been known.

This relay connector 1 is composed of a male connector 3 and a female connector 4, which are connected and detached by a joining ring 2.

The male connector 3 has a plurality of connecting pipes 7, 7 . ...
The plug pipe part 8 of the connecting pipe 7 is made to protrude from the joint surface of the base plate 5, and the hose nipple part 9 of the connecting pipe 7 is made to protrude to the other side, and the hose nipple part 9 is stepped. Tapered part 1 with line 11 as a sharp edge
0, and a joining ring 2 having a female thread 12 is rotatably attached to the base 5.

Further, the female connector 4 has socket holes 14, 14, 14, 14, 14, 14, 24, 32, 32, 42, 42, 34, 32, 34, 34, 34, 34, 34 . A connecting pipe 1 is provided with a socket pipe part 16 and a hose nipple part 17 which are bored into the socket hole 14 and connected to the plug pipe part 8.
5, and attach the male connector 3 to the hose nipple part 17.
Similarly to the above case, a tapered part 18 is formed with the dashed line 19 as a sharp edge, and a male screw 20 is provided on the outer peripheral surface of the base 13 to screw into the connecting ring 2 and connect the male and female connectors 3 and 4. It is set up.

The hose nipple parts 9 and 17 in such conventional relay connectors have a tapered part 10.18 with a sharp edge formed by the dashed line 11.19, so when the tube 21 is inserted into the tapered part 10.18, the sharp edge Although it can bite into the inner surface of the elastically contracting tube 21 and strengthen the connection between the two, an extremely large force is required to pull out the tube 21 from the hose nipples 9 and 17, resulting in poor workability. If the elastic contraction force of the tube 21 decreases as the tube 21 ages, the sharp edges of the inner surface of the tube 21 will not be sufficiently wedged, and there is a risk that the tube 21 may easily come off from the hose nipple portions 9, 17.

In order to solve this problem, it is possible to consider measures such as providing a tapered part with a chamfered dotted line in the hose nipple part, and clamping the tube fitted into the tapered part between the tapered part and the tapered part using a clamp nut. However, in a multi-tube relay connector as shown in Fig. 1, the clamp nut must be tightened for each hose nipple, so the work of inserting and removing the tube 21 is complicated in proportion to the number of hose nipples. become

The present invention addresses the above-mentioned conventional problems, and provides a multi-tube relay connector in which, when the connector is separated, tubes can be easily attached to and detached from each hose nipple portion with a small force, and each hose nipple portion The purpose of this is to automatically tighten all the tubes when the connector is connected with tubes fitted to the tubes so that they do not easily come off from the hose nipple.

In order to achieve the above object, the multi-tube relay connector of the present invention is composed of a male connector and a female connector that connect and separate from each other, and a large number of connections that are connected to each other by joining the two connectors on the joining surface of the base of both connectors. Each tube is provided,
The hose nipple portions of the connecting pipes are made to protrude to the other surface of the base, and a tapered portion is formed at the rear end with a chamfered dashed line for fitting the tube to these hose nipple portions, and a male connector and A clamp board having a large number of clamp holes for sandwiching the tubes fitted in each of the hose nipple parts between the base of the female connector and the tapered part thereof is attached so as to be removable and detachable, and both clamp boards are provided with: These clamp discs are fastened to each other to join the joint surfaces of both bases to each other, and at the same time, a fastening means is provided that presses the inner surface of the clamp hole in each clamp disc to the tube fitted into the tapered part of the connecting pipe. It consists of
