Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable sealing method and apparatus.

Conventionally, in this type of method and apparatus, as shown in FIGS. 1 and 2, the cable seal 2 is attached to the side wall of the housing 10 so that the inner diameter of the hole 3 is smaller than the outer diameter of the cable 1. However, since the outer diameter tolerance of the cable 1 usually varies by ±10%, it is difficult to insert the cable with an outer diameter close to the upper limit. In particular, the cable 1 is inserted through the trap cable seal 2 as shown in FIG. 2 to glue 6
When moving to the side, the adhesive 6 applied to the outer periphery of the cable l is squeezed off at the end of the cable seal 2, so that an effective adhesive area cannot be obtained. On the other hand, for cables that are close to the lower limit of the outer diameter tolerance, the cable seal 2 tends to move relative to the cable 1 (and even if adhesive is used, it has the disadvantage of poor workability and problems with sealing performance). Ta.

The present invention aims to eliminate such conventional drawbacks and provide a cable sealing method and device with good sealing properties and high workability. A lip is provided inside the insertion hole to protrude along its inner circumference, and a tapered part is provided at one end of the cable seal, the inner diameter of which gradually increases from the cable insertion hole toward the outside. By inserting a cable into the hole and applying adhesive to the outer periphery of the cable at a predetermined position at the front of the tapered part of the cable, slide the cable seal along the cable to the side where the adhesive is applied. The adhesive is relatively introduced into the tapered portion to adhere the cable and cable seal to each other.

An embodiment of the present invention will be described below with reference to the drawings.

That is, in FIGS. 6 and 7, the cable seal 2
has a cable insertion hole 3 for inserting the cable 1 on one axis, and a lip 4.4 that absorbs variations in the outer diameter of the pair of cables 1 is provided along the inner circumference in the insertion hole. hand,
They are protruded at predetermined intervals. Further, one end of the cable seal 2 is provided with a tapered portion 5 whose inner diameter gradually increases toward the outside of the cable insertion hole 3.

In the above configuration, the cable seal 2 is attached to the cable 1
It is installed as follows.

That is, the cable 1 is inserted into the cable insertion hole 3 of the cable seal 20, and then the adhesive 6 is applied to the outer periphery of the cable at a predetermined position on the front side of the tapered part 5 of the cable 1, and the cable is inserted as shown in FIG. By sliding the seal 2 along the cable 1 toward the side where the adhesive 6 is applied, the adhesive is relatively introduced into the cable insertion hole 3 through the tapered portion 5, thereby causing the cable 1 and the cable seal 2 to be separated from each other. is glued to.

As described above, this invention includes a lip protruding inside the cable insertion hole of the cable cool along its inner periphery, and a lip extending gradually outward from the cable insertion hole at one end of the cable seal. A tapered part with an increasing inner diameter is provided, and adhesive is applied to the outer periphery of the cable at a predetermined position at the front of the tapered part of the cable, and the cable seal is slid along the cable toward the adhesive-applied side. The adhesive is relatively guided into the cable insertion hole through the tapered part and adhered to the cable and cable seal, resulting in extremely good sealing performance and increased tensile strength of the cable against the cable seal, making it easier to operate. My sex is as high as my elbow. Further, since variations in the outer diameter of the cable are absorbed by the lip, there is an advantage that uniform sealing performance can be obtained.
