Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a core holder for preventing induced noise, which uses a split cylindrical core attached to a signal line connecting electronic devices.

[Conventional technology]

2. Description of the Related Art Conventionally, signal lines connecting devices such as electronic devices have been installed by covering a cylindrical magnetic core in order to prevent induction noise caused by discharge of static electricity charged in the human body. A split cylindrical core is usually used in conjunction with a signal line extending from a connector device attached to an electronic device. For example, two divided core pieces each having a semi-circular cross section and a central groove in the flat center thereof are placed facing each other, and the signal line is passed through the center hole formed by the core pieces. In this state, the cores were maintained in their assembled state by tightening them using narrow clamping metal fittings.

[Problem that the invention attempts to solve]

In the conventional tightening fittings as described above, when the claws at the tips of the tightening fittings are hooked to the ridges of the two divided cores and fixed, it is necessary to spread the arms of the tightening fittings. Therefore, there were problems in that not only was it difficult to attach the tightening fittings, but additional means were required to attach the core tightened with the tightening fittings to the mounting board for signal lines and the like.

[Means for solving problems]

In the holder for the core for preventing induced noise according to the present invention, the two-part core is combined to form a center hole through which the signal line passes, and then the two-part case is combined into a core holder. Constructed to hold combined cores. In this core holder, each of the two core cases made of resin is housed with the groove side for forming the center hole facing the open side of the case. Fix the core in the case with the core fixing claws provided. The core cases, each with a core fixed in this way, are combined so that the grooves of the cores meet to form a center hole, and the core cases, which are divided into two by elastic claws provided on the outer wall of the core case, are combined into one body. The combination is fixed to form a core holder. A part of the core case is further provided with fixing means for fixing the holder to an external fixing member.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In FIG. 1, reference numeral 1 designates one of the two core cases, which is molded from resin and has a box shape as a whole, and has a space for housing the core 10 shown in FIG. 3. The longitudinal side walls 3 and 4 of this case 1 are provided with a semicircular notch 3' having a diameter approximately equal to the hole diameter formed when the two cores are combined, and a third
When the core 10 shown in the figure is stored, the hook 5 that fits into the hook groove 11 formed at the edge of the groove 12 of the core moves toward the space of the case 1 so that the core is fixed in the space. It is extended and provided. Also case 1
A push spring 6 is provided at the bottom to elastically urge the housed core toward the hook 5. core 1
0 first attaches one of the hooking grooves 11 at both ends to the hooking claw 5.
Then, using the elasticity of the case 1 made of resin, the other side wall is pushed out and the hook hook is hooked into the hook groove 11 on the other side. In this case, since the push spring 6 presses the core 10 toward the hook 5, the core 10 is held in a stable state within the case.

FIG. 2 shows the other case 2 which is matched with the one case shown in FIG. 1, and the other core is housed in the space with a structure similar to that of the first case. By assembling these pair of cases 1 and 2 facing each other, the cores housed in each case are combined.In this case, by inserting the signal line into the groove 12, the cores can be combined. The hole (not shown) formed by the two grooves 12 is made to penetrate through the hole (not shown).

A combination of elastic claws 8 and hooks 9 is used as a device for holding the two-part core case that has been combined in this manner. As an application of the present invention, one of the two core cases is provided with elastic claws 8 on both sides of the side wall of the case, and when the cases are combined, the elastic claws 8 are attached to the corresponding hooks 9 provided on the outer wall of the other case. It is formed so that it can be caught.

Further, the case 2 is provided with a mounting protrusion 13 for attaching the holder to the fixed member, and the holder can be fixed to the fixed member by passing a mounting screw through a hole formed therein. The attachment protrusion 13 may be provided on the case 1 or may be provided on both cases 1 and 2.

[Effect of idea]

According to the core holder of the present invention, it is possible to elastically position and hold the two-split core in each of the two-split cases forming the holder so that its storage position does not move, by simply fitting the core into the case. By simply snapping the pair of cases together, the signal line can be passed through the hole in the core that is formed as a result, and the holder itself can be fixed. Effects such as being able to fix the holder to the fixing member extremely easily can be obtained by this means.
