JPH08275358A - Coupling for cable protective cover - Google Patents

Abstract

PURPOSE: To provide a device which can surely couple cable protective covers and does not allow the cover to be decoupled even if external load works on them. CONSTITUTION: A cut 4, which is made by cutting a lock part 2 and a receiving part 3, and a through hole 5, which corresponds to the cut part 4, are provided at one end of either of cable protective covers A in a pair, which are used by providing a lock part at one end in longitudinal direction of one hand and a lock part at one end of the other hand and coupling them witch each other capably of locking and separation. Moreover, at the external surface on the side of the end of the other protective cover is a coupling pin 6 to fit in the through hole 5 projected in the position corresponding to the lock part or the receiving part 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for connecting a cable protection cover which is used by being attached to a cable so as to surround the cable in order to prevent damage to the cable due to contact with standing trees.

[0002]

2. Description of the Related Art As a cable protection cover, a receiving portion is provided at one end along a longitudinal direction of a cover main body having an arcuate cross section, and a locking portion is projected at the other end, and the locking portion is engaged with the receiving portion. There is a structure in which the cable is detachably locked and assembled so as to surround the cable, but when the cable protection cover is connected and used, the end portion of the cable protection cover is connected to a separate so-called joint material. I am trying to connect by inserting.

[0003]

In the conventional example, since the joint member is simply inserted and connected, the cover body can maintain the connected state to some extent by the elasticity of the cover, but it is easy to apply the external force. There is a risk of leaving.

The present invention was devised with the object of providing a device that does not easily come off even when an external force is applied.

[0005]

A receiving portion is provided at one end of a cover main body made of an elastic plate along a longitudinal direction, and a locking portion is provided at the other end of the cover main body, and the locking portion is separated from the receiving portion. In a cable protection cover that is assembled so as to surround the cable by being locked as much as possible, a locking portion and a receiving portion are cut off at one end of a pair of cable protection covers that are connected to each other. A cutout portion and a through hole facing the cutout portion are provided, and a connecting pin for locking the through hole is provided on the outer surface on the end side of the other one of the protective covers so as to face the locking portion or the receiving portion. Position and project.

[0006]

The cable is arranged inside the cover main body so as to separate and open the locking portion and the receiving portion of each of the pair of protective covers to be connected, and the cables are combined with the cable. After locking, align the ends of the receiving part and the locking part that are locked to each other on one protective cover with the notches provided on the end of the other protective cover, and The pair of protective covers are connected to each other by engaging the connecting pin provided on the one protective cover with the through hole provided on the other one of the protective covers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a device for connecting a cable protective cover according to the present invention. FIG. 1 is a partially cutaway side view showing a connected state, and FIG. 2 is an exploded perspective view of essential parts.

In the embodiment, a notch 4 formed by cutting off the engaging portion 2 and the receiving portion 3 and a through hole 5 facing the notch 4 are provided on one end side of the protective cover A, and another Although the connecting pin 6 that engages with the through hole of the other protective cover connected to one end side is provided, in the drawing, only one end side of the protective covers A, A to be connected is shown.

However, the protective cover A is made of an elastic synthetic resin plate, and one end along the longitudinal direction of the cover main body 1 having an arcuate cross section has a slightly grooved cross section, and the receiving portion 3 is formed. At the other end, the engaging portion 2 is provided in a bent shape having an L-shaped cross section so as to project outward from the cover body 1.

The locking portion 2 and the receiving portion 3 are arranged such that the tip end piece 2a of the locking portion 2 is arranged inside the tip end piece 3a of the receiving portion 3 and are locked, and the locking state is mainly the cover. It is maintained by utilizing the elasticity of 1.

At one end of the pair of cable protection covers A, A, which are connected to each other, a notch 4 formed by cutting out the engaging portion 2 and the receiving portion 3 as described above and the notch 4 face each other. In this way, the cover main body 1 is provided with a through hole 5, and a connecting pin 6 that engages with the through hole 5 is provided on the outer surface of the other one of the cover main bodies 1 on the end side. The protrusion is provided so as to face the receiving portion 3.

The connecting pin 6 is constructed by screwing a nut 6b onto a screw rod 6a and tightening it on the cover main body 1, and covering the screw rod protruding from the cover main body 1 with a cap 6c.

Therefore, a pair of protective covers A to be connected,
A cable C is arranged inside the cover main body 1 and combined with the cable C so that the respective locking portions 2 and the receiving portions 3 of A are separated from each other. After locking, the ends of the locking part 2 and the receiving part 3 of the one protective cover, which are locked to each other, are aligned with the notches 4 provided at the ends of the other one of the protective covers, and protected. By using the elasticity of the covers A and A to lock the connecting pin 6 in the through hole 5,
The pair of protective covers A and A are connected to each other, and further other protective covers are sequentially connected and used as necessary.

In the embodiment, the protective cover has a cylindrical shape, but it may be an elliptic cylindrical shape or a rectangular cylindrical shape.

[0015]

The present invention has the configuration described above,
A receiving part is provided at one end along the longitudinal direction of the cover main body made of an elastic plate with an arcuate cross section, and a locking part is projected at the other end, and the locking part is disengageably engaged with the receiving part. Thus, it is possible to reliably connect the cable protection cover that is assembled to the cable so as to surround the cable, and to provide a device that does not easily come off even when an external force is applied.
