Description

TECHNICAL FIELD

[0001] The present application relates to a support strip suitable for being coiled into a support tube for supporting a rubber body and a support tube coiled from the support strip. BACKGROUND

[0002] In the prior art, a tubular rubber body (for example, a cold shrink tube) needs to be expanded (that is, the inner diameter is enlarged) to a predetermined expansion state before installation. After being expanded to the predetermined expansion state, a support tube needs to be inserted into the rubber body to maintain the rubber body in the predetermined expansion state. After the rubber body is installed on a corresponding part, such as a terminal or a cable, the support tube can be removed by pulling one end of the support tube.

[0077] like Figures 1 to 13 As shown, in an exemplary embodiment of the present invention, a support tube 1 is also disclosed, which is used to support a rubber body.

[0078] like Figures 1 to 13As shown, in one exemplary embodiment of the present application, the welding of the support tube 1 can be achieved by integral heating of the support tube 1 by ultrasonic waves or hot air. During the integral heating of 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 other than the welding zone 101, and thus the welding zone 101 of the support tube 1 melts first than other regions of the support tube 1 other than the welding zone 101. In this way, it is possible to ensure that the support tube 1 is melted and welded only at the welding zone 101, and not at other regions.

[0079] As shown, in the illustrated embodiment, the support tube 1 further comprises a pull strap 20 attached to one end of the support strip 10, so that the coiling of the support strip 10 can be released by pulling the pull strap 20. In this way, it is possible to extract and remove the support tube 1 from the rubber body by pulling the pull strap 20. Figures 1 to 13
