Description

Support bar and support tube
Technical Field
The present invention relates to a support bar adapted to be wound into a support tube for supporting a rubber body and a support tube wound by the support bar.
Background
In the prior art, a tubular rubber body (e.g., cold shrink tube) needs to be expanded (i.e., the inside diameter is enlarged) to a predetermined expanded state before being installed. After being expanded to a predetermined expanded state, a support tube needs to be inserted into the rubber body to hold the rubber body in the predetermined expanded state. After the rubber body is mounted to a corresponding component, such as a terminal or cable, the support tube may be removed by pulling on one end of the support tube.
In the prior art, the support tube is typically made by coiling a support bar. In order to ensure that the support tube does not loosen, welding is required in multiple areas of the support tube. At present, the most commonly used welding scheme is ultrasonic welding or hot air welding, however, the existing welding scheme has poor stability, and excessive welding or cold welding easily occurs. If the welding is too over, the support bar is difficult to remove during use. If the false welding occurs, the support tube is easy to collapse when in use.

As shown in fig. 1 to 13, in the illustrated embodiment, the burrs 101f may be formed by cutting, and the plurality of welding areas 101 may be uniformly spaced apart along the length direction of the strip-shaped body 100. The shape of the welding area 101 is not limited to the illustrated rectangle, but may be any other suitable shape, for example, elliptical. The shape of the through hole 101h is not limited to the square shape shown in the drawing, but may be any other suitable shape, for example, a circular shape.
As shown in fig. 1 to 13, in an exemplary embodiment of the present invention, a support tube 1 is also disclosed, the support tube 1 being for supporting a rubber body. The support tube 1 includes a tube body 10a. The pipe body 10a is coiled by the support bar 10. The support bar 10 is spirally wound, and the first and second ribs 112 and 122 of the support bar 10 are engaged with the second and first grooves 121 and 111, respectively. After being coiled into the pipe body 10a, the support pipe 1 is welded at the aforementioned welding area 101.
As shown in fig. 1 to 13, in an exemplary embodiment of the present invention, welding of the support tube 1 may be achieved by integrally heating the support tube 1 by ultrasonic waves or hot air. In the process of integrally heating the support tube 1, since the surface area of the welding zone 101 is increased, the welding zone 101 of the support tube 1 absorbs heat faster than other regions of the support tube 1 than the welding zone 101, and thus the welding zone 101 of the support tube 1 melts earlier than other regions of the support tube 1 than the welding zone 101. In this way, it is ensured that the support tube 1 is melted and welded only at the welding zone 101 and not at other areas.
As shown in fig. 1 to 13, in the illustrated embodiment, the support tube 1 further includes a pull band 20 attached to one end of the support bar 10 so that the support bar 10 can be unwound by pulling the pull band 20. In this way, the support tube 1 can be extracted and removed from the rubber body by pulling the pull tape 20.
