Description

[Detailed description of the invention] The present invention has a half-split elliptical cylindrical synthetic resin cover main body with engaging pieces provided oppositely on the outer edges of the divided parts, and the divided parts are expanded through these engaging pieces. Regarding the connector cover that is attached to the wire joint,
In particular, the present invention is characterized in that it can be used flexibly even if the wire diameters of the main wire and branch wires on the draw-out side vary in thickness and thickness.

Conventionally known connector covers of this type can only be used for wires with a fixed diameter, and it is necessary to prepare a wide variety of sizes that match the wire diameter, resulting in high manufacturing costs. It was necessary to be extremely careful not to use it incorrectly, and there were also various problems, such as having to carry various sizes of equipment at all times during construction work.

The present invention was made to provide a connector cover that eliminates such conventional problems, and the elliptical cylinder body is divided in half to allow expansion. A holding cylinder for the main electric wire is extended on one side, and holding cylinders for the main electric wire and branch line on the drawer side are arranged vertically on the other side, and a thin wall part is provided around the outside end of the holding cylinder on the drawer side. At the same time, a lid piece is provided in the lower half of the outer end of the holding cylinder, and the lid piece is formed into segments according to the dividing positions of the cover body, and the inner wall of the cover body is provided with a lid piece located on both left and right sides of the storage part. A plurality of protrusions are provided on the inner wall of each holding cylinder to serve as a stopper for the electric wire joint and a support for the electric wire, and a plurality of protrusions are provided on the inner wall of each holding cylinder to form a gripping portion for clamping the electric wire.

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

In the figure, 1 is a cover body made by dividing an elliptical cylindrical body made of a semi-rigid synthetic resin having elasticity such as polyethylene resin into halves in a straight line in the longitudinal direction at one edge on the long diameter side. The cover main body 1 has engaging pieces 3a and 3b arranged opposite to each other on the outer edge of the divided portion 2. One of the engagement pieces 3a is provided with a protrusion 4a having a downward hook at the tip at the center of the inner side, and the other engagement piece 3b is provided with an upward hook at the tip at the bottom of the inner side. A protrusion 4b is formed which detachably engages with the protrusion 4a.

Inside the cover body 1, a compression sleeve E was attached to the conductor wire D which was exposed by peeling off the insulation coating C of the main wire A and the branch wire B, approximately at the center in the longitudinal direction, and was tightened and fixed. A housing part 5 for housing the wire joint part F is provided, and a holding tube 7 for the main wire A is provided on one of the right and left sides of the housing part 5 through a tapered part 6, and a holding cylinder 7 for the main wire A on the draw-out side is provided on the other side. and branch line B
The holding cylinders 8 and 9 are positioned one above the other and are connected to each other in a continuous manner. Further, a groove-shaped thin wall portion 10 is provided around the outer end of the holding cylinders 8 and 9 on the drawer side, and a dividing portion 2 of the cover body 1 is provided at the outer end of the holding cylinder 9.
Lid pieces 11a and 11b are formed by dividing the lid pieces 11a and 11b.

Furthermore, two triangular protrusions are provided on the inner wall of the cover body 1 on the left and right sides of the accommodating portion 5 to form stoppers 12, 12 for preventing movement of the wire joint F and the compression sleeve E. , trapezoidal protrusions are provided on the outside of these stoppers 12, 12, respectively, to support the electric wires 13, 1.
form 3. Furthermore, each holding cylinder 7, 8, 9
A plurality of protrusions are provided on the inner wall of each wire at equal intervals in the circumferential direction to form a grip portion 14 that contacts the peripheral surfaces of the main wire A and the branch wire B.

Next, the use of the connector cover of the present invention formed as described above will be explained. First, FIGS. 7 and 8 show an example of use for a wire joint F where a main wire A and a branch wire B are joined.
The cover main body 1 disengages the protrusions 4a and 4b and spreads the engagement pieces 3a and 3b in the front-rear direction to open the dividing portion 2, and connects the electric wire joint F provided to the overhead electric wire through the gap. If the engaging pieces 3a and 3b are aligned with the electric wire joint part F housed in the housing part 5, and the protrusions 4a and 4b are pressed and engaged with each other,
As shown in FIG. 8, the wire joint F is prevented from sliding at both ends of the compression sleeve E by stoppers 12, 12 provided on both left and right sides of the housing portion 5, and the wire main line A is prevented from sliding by the support portion 13 and the holding cylinder. It is held and further the holding cylinder 7
The branch line B is held by a gripping part 14 made up of a plurality of protrusions provided therein, and the branch wire B is pulled out from the holding cylinder 8 while being supported by the supporting part 13 and is inserted into the holding cylinder 8. Since it is firmly held by the provided gripping part 14, it will not slide or rotate during use. Further, since the holding tube 9 which is not used and the electric wire is not pulled out is closed by the cover pieces 11a and 11b, rainwater, dust, etc. do not enter the holding tube 9.

Figures 9 and 10 show an example of use in a wire joint F in which a compression sleeve E is applied with the conductor D of a branch line B in contact with the exposed part of the conductor D provided midway through the main wire A. In this case, on the draw-out side, the branch wire B is pulled out from the holding tube 8, and the main wire A
The lid pieces 11a and 11b can be pushed out from the inside to the outside and pulled out for use without forming a gap.

In addition, Figures 11 and 12 also show examples of how to draw out the main wire A and branch line B from the drawer side, but the wires shown in this figure are smaller than those shown in Figures 9 and 10. This shows how to use the main line A when it has a large diameter. That is, in such a case, the holding cylinder 8,
Cut off the tip of 9 at the thin wall part 10 and make the lid piece 11
A and 11b are eliminated so that a main wire A having the same size as the inner diameter of the holding cylinder 9 can be pulled out.

As explained above, the connector cover of the present invention holds the main wire on one of the left and right sides of the accommodating part that accommodates the wire joint, and has a holding cylinder on the other side for pulling out the main wire and the branch wire. At the same time, the lower half of the outer end of this holding cylinder can be opened and closed with a lid piece.For example, when pulling out only one branch line, it can be pulled out from a holding cylinder that does not have a lid piece and a lid piece is provided. The holding tube should be used with it closed, and if the branch line and the main wire are being pulled out, and the main wire has a slightly small diameter, there will be no gap when the cover piece is pushed outward. If the main wire has a relatively large diameter, it can be used in a variety of ways, such as by cutting off the cover piece at the thinner part located on the outside of the holding cylinder. It can be used whether there is one or two electric wires on the draw-out side, and it can also be used even if the diameter of the wires to be drawn out is different.

Therefore, it is easy to use because it is flexible and can be used without having to prepare everything that matches the wire diameter, there is no need to worry about selecting the wrong size, and manufacturing costs can be reduced by reducing the product size. There is a practical benefit to being able to do this.
