Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a holder for attaching a cylindrical core to the signal line by passing it through the signal line, and at the same time fixing the cylindrical core to the signal line.

[Conventional technology]

In order to prevent noise induced in reciprocating signal lines that connect devices of digital equipment, a cylindrical core is passed through the signal line and attached to the signal line.

A split cylindrical core is usually used for the signal line after the connector device. Cover the signal wire with two split core pieces (for example, a semi-cylindrical core piece, a plate-like core piece with a semicircular central groove, etc.) and butt them together using a case-like holder, a binding cord, a tightening fitting, etc. It was held in a cylindrical core.

[Problem that the invention attempts to solve]

The above-mentioned cylindrical core cannot be easily fixed to the signal line, and movement of the core may cause defects such as chips on the exposed part of the core, which may cover the signal line. It needed to be fixed. Another problem was that fixing the core to a wall made rewiring the signal lines extremely troublesome.

An object of the present invention is to provide a holder that allows a cylindrical core to be easily and quickly passed through a signal line and held therein, and at the same time can be fixed to the signal line.

[Means for solving problems]

The holder for a cylindrical core according to the present invention is intended to solve the above-mentioned problems.The holder for a cylindrical core according to the present invention is designed to solve the above-mentioned problems. A strap with a plurality of engagement teeth is provided on one outer surface of the peripheral wall that faces each other with the cut surface sandwiched between the walls, which are divided into two parts with a part left thin, and the other outer surface is provided with a strap with a plurality of engagement teeth inside. A retaining ring is provided, and a claw portion consisting of a core engaging piece extending inwardly of the cylinder and a signal line retaining claw extending toward the center of the through hole is provided on the inner circumferential surface of the through hole in the side wall. do.

〔Example〕

Examples will be described below.

The holder 1 is made of flexible resin, and has a shape in which a lower box 2 and an upper box 3 are connected by a hinge part 4 as shown in FIG. A hollow cylindrical body consisting of a side wall 6 and a side wall 6 is cut into approximately two equal parts by cutting with a thick cutter, leaving a part of the peripheral wall 5 thin as a hinge part 4. The lower box 2 has a depth dimension in which the through hole 21 of the side wall 6 is semicircular, and the upper box 3 has a depth dimension in which the through hole 31 in the side wall 6 is arcuate, smaller than the semicircle. Only the peripheral wall 5 connected to the hinge part 4 has approximately the same height dimension as the lower box 2.

A locking ring 7 having locking teeth (not shown) inside is provided on the outer surface of the peripheral wall 5 of the lower box 2 close to the cut edge, and a plurality of locking teeth are provided on the outer surface of the peripheral wall 5 of the upper box 3. A strap 8 having a shape 81 is provided corresponding to the locking ring 7 of the lower box 2.

A core engaging piece 91 extending horizontally inward and a signal line locking claw 92 extending upward are located at the center (bottom in the figure) of the inner peripheral surfaces of the through hole of the upper box 2 and the lower box 3. A claw portion 9 (a total of four wedge-shaped claw portions in the figure) is provided.

FIG. 2 shows a state in which two equally divided core pieces of the cylindrical core 10 are fitted into the lower box 2 and the upper box 3 in the holder 1. The axial dimension of the cylindrical core 10 is slightly smaller than the inner dimension of the holder 1 (in this case, the inner dimension of the long side of the lower box 2), and the dividing surface of the core piece is approximately aligned with the opening end surface of the lower box 2. For example, the outer peripheral surface of the core may be either cylindrical or prismatic, and the diameter of the central through-hole of the core may be at least equal to the diameter of the through-hole of the side wall 6 of the holder 1. In the case of the cylindrical core 10 shown in FIG.
is brought into contact with the end surface of the core piece, the core piece is pushed into the lower box 2 (upper box 3) and stored, and the core engaging piece 91 is engaged with the inner circumferential surface of the core center hole (groove).
Therefore, there is no need to worry about the core piece coming off from the holder 1. Pass the signal wire 11 of the required thickness through the central groove of this core piece (for example, inside the lower box 2), cover the upper box 3, and insert the strap 8 through the locking ring 7 and pull it down (see Figure 3). By meshing and tightening the mating teeth 81 with the locking teeth in the locking ring 7, the core pieces are butted against each other and the cylindrical core 10 is held, and the signal wire locking claws 92 of the claw portion 9 are engaged with the outer surface of the signal wire 11. The signal line 11 is held in elastic contact with the signal line 11 .

FIG. 4 shows another structural example of the claw portion 9 as a partially enlarged view of section A in FIG. This claw part 9 is made individually from a resin material that is more flexible than the holder 1, and includes a core engagement piece 93 with a semicylindrical bulge at the top end, and a plurality of claws arranged in a stepped manner on the outer surface. It consists of a formed signal line locking pawl 94 and an L-shaped mounting plate 95. The mounting plate 95 is attached to the holder 1 by inserting the legs of the mounting plate 95 into mounting holes previously provided in the side wall 6 of the holder 1 (indicated by chain lines in FIG. 4). This core engaging piece 93 has the advantage that it can be stored in the lower box 2 (upper box 3) simply by pressing the core piece. The signal line locking claw 94 can be made larger in height than the locking claw 92 shown in FIG. Since it faces outward, it has the advantage of being able to grip the signal line 11 more reliably.

[Effect of idea]

As explained above, according to the present invention, it is possible to provide a holder that allows a cylindrical core made of two divided core pieces to be easily and quickly passed through a signal line and held therein, and at the same time is fixed to the signal line.
