Description

[Detailed Description of the Invention] The present invention relates to a split body connector that connects split bodies at split surfaces.

Protecting long bodies such as submarine cables and water pipes on the seabed - 9 Protection pipes or sinkers, etc. that fix these long bodies so that they do not move on the seabed, are manufactured in parts and are used to protect long bodies during use. The divided surfaces are connected while being fitted to the outer periphery.

Conventional split body connectors of this type require precision during manufacture and have the disadvantage of being expensive.

An object of the present invention is to provide a split body connector that is easy to manufacture and can be manufactured at low cost.

The divided body connector according to the present invention includes a connecting piece whose base is fixed to the split surface of the divided body divided by the split surface and whose distal end sides protrude to the outside so as to face each other along the split surface; It has a 7-shaped groove and a wedge portion formed at the two prongs of this groove, and the ends of the two connecting pieces accommodated in the 7-shaped groove are deformed into a Y-shape by the wedge portion and fixed to prevent removal. the 7-shaped groove of the clip is composed of a connecting piece insertion groove and a pair of branch grooves formed by splitting into two at the tip thereof, and each of the branch grooves is formed on the inclined wall surface of the wedge portion. and a parallel inclined wall surface adjacent thereto.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The drawing shows an example in which the present invention is applied as a connector for a protection pipe that protects a long body such as a submarine cable.

As shown in FIG. 1, the protective tube 1 is divided along the longitudinal direction at a dividing surface 2, and a pair of divided bodies IA and IB are formed of, for example, reinforced concrete.

A connecting tool 3 for connecting the divided bodies IA and 1B at the split surface 2 is provided at the split surface 2.

That is, the divided bodies IA, I at the location where this connector 3 is provided
A recess 4 is formed on the surface of B, and corresponding to the recess 4, each of the divided bodies IA and IB has l pairs of L-shaped connecting pieces 5,
5 is provided so that its base portions 5A, 5A sides are embedded in the respective divided bodies IA, IB, and the tip side portions 5B, 5B are made to protrude outside along the split surface 2.

A metal clip 6 is fitted into the recess 4 to connect the two divided bodies IA and IB by pinching the connecting pieces 5, 5.

A Y-shaped groove 7 is formed in this lip 6, and this Y-shaped groove 7 is formed in the lip 6.
A wedge portion 8 is formed at the two-pronged portion of the character-shaped groove 7.

The Y-shaped groove 7 is made up of a connecting piece insertion groove 7A and a pair of branch grooves 7B formed by splitting into two at the tip thereof, and each branch groove 7B is adjacent to the inclined wall surface of the wedge portion 8. It is formed by parallel inclined walls.

In such a connecting tool 3, when the split surfaces 2 of the divided bodies IA and IB are brought together, the connecting pieces 5 and 5 attached to the respective divided bodies IA and IB will also fit into the recess with their wide surfaces facing each other. It will exist in 4.

In this state, when the clip 6 is driven into the recess 4, the connecting pieces 5, 5 are pushed into the Y-shaped groove 7, and the wedge part 8 of the clip 6 is driven into the joint at the tip of the connecting piece 5.5. 5
, 5 are pushed open in a Y-shape.

In this state, the connecting pieces 5, 5 are locked so that they cannot be removed from the clip 6.

Moreover, each branch groove part 7B of the Y-shaped groove 7 is formed by the inclined wall surface of the wedge part 8 and the parallel inclined wall surface adjacent to this, so that the wedge part 8 is driven between both connecting pieces 5. When each connecting piece 5 deforms away from the wedge part 8, each branch groove part 7B
This can prevent the device from becoming free inside.

Therefore, the movement of each connecting piece 5 within each branch groove 7B can be suppressed, and each connecting piece 5 can be prevented from coming out of the clip 6.

In addition, this type of connector 3 can be used not only to connect the split surfaces of protective pipes and sinkers as described above, but also as a connector for cable cleats that clamp multiple power cables laid in trunk channels on land. It can also be used as a connector for other divided bodies.

As explained above, the split body connector according to the present invention can be connected simply by driving a clip into the connecting piece, so that the connecting work can be easily performed.

Furthermore, since this connector can be mass-produced without requiring precision, costs can be reduced compared to conventional products.

This connector uses a clip that has a Y-shaped groove and a wedge formed at the two prongs of this groove, and the Y-shaped groove is particularly divided into two at the connecting piece insertion groove and its tip. A pair of branch grooves are formed, and since these branch grooves have a structure formed by an inclined wall surface of the wedge portion and an adjacent parallel inclined wall surface, the Movement of each connecting piece can be suppressed.

Therefore, each connecting piece can be reliably prevented from coming out from the clip.
