Embodiment Construction

[0015] Refer to attached Figure 1~3 , The universal joint for the submarine optical cable joint box is composed of three main components: joint 1, bushing 2, connecting sleeve 3, and three main components. The joint 1 is provided with a ball head (ball) 1-1, and the bushing 2 is set on the ball head (ball) 1-1 of the joint 1 and connected with a pin 5; on, connected with pin 6. see figure 1 and figure 2 . The bending limiter 7 is connected with the other end of the connecting sleeve 3, and the joint 1 is connected with the rigid part of the joint box. In this way, the bending limiter 7 and the splice box body 8 are connected with a universal joint through the submarine optical cable splice box, see image 3 .

[0016] The central axis of the joint 1 has a through hole 1-2 for wearing the optical cable 4, the ball head has a ball head through hole 1-3; the side of the bush 2 has a symmetrical counterbore 2-1. The joint 1 and the bushing 2 are connected by two pins 1-5,...

Abstract

The invention provides a universal joint for a submarine optical cable connector box relating to a connecting device for protecting optical cable conductors. The universal joint for a submarine optical cable connector box comprises a joint, a lining and a connecting sleeve, wherein the joint is provided with a ball joint; the lining is sleeved on the ball joint of the joint; and the connecting sleeve is sleeved on the lining. By the transition of the lining, the joint and the connecting sleeve can rotate optionally along a central axis, and the optical cable is not pulled by the generation of excessive bending. The universal joint for a submarine optical cable connector box is reasonably designed and simply structured; and the optical cables in the universal joint can be curved optionally without being bended and pulled. The structure is more suitable for the connection of rigid parts in the optical cable joint and the bending restrictor. The structure of the universal joint for a connector box provided by the invention is simple, the bending performance is good, and a whole length component of the original connector box is divided into three parts which are a bending restrictor part, a connector box steel straight part and a bending restrictor part at another end, so that the construction and maintenance are convenient.

Description

technical field [0001] The invention relates to a universal joint for a submarine optical cable splice box, which relates to a connection device for protecting the core of an optical cable. Background technique [0002] The conventional subsea optical cable splice box is connected with the rigid part of the splice box with a bend limiter, but because the integral part of the joint is very long, it is easy to tear the bend limiter or the transitional bending of the optical cable when the joint passes through the drum. . Contents of the invention [0003] The object of the present invention is to provide a kind of universal joint for submarine optical cable splice box in view of the above-mentioned deficiencies. The limiter rotates around the center axis of the joint box through a large angle. At the same time, the optical cable will not produce transitional bending and tension. [0004] The universal joint for the submarine optical cable joint box is realized by adopting...
