Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a high voltage lead wire clamper for gripping a high voltage lead wire and holding the high voltage lead wire at a predetermined spatial distance from other members.

[0002]

[Prior art]

 Conventionally, in the high voltage lead wire connected to the anode cap of the CRT tube of the OA equipment or the like, the routing of the high voltage lead wire is limited due to restrictions such as the shape of the OA equipment and the mounting position of the CRT tube, and other members are used. Insulation performance may not be guaranteed due to contact or proximity, and in order to secure a spatial distance from other members, a ring-shaped gripping part that grips the lead wire as shown in Fig. 2 (a) is used. The formed clamper is used to prevent the high voltage lead wire from approaching other members within a certain distance. In this case, as shown in Fig. 2 (c), it may not be possible to ensure a certain distance depending on the shape of other members or the skill of the mounting work. There is a problem such as using the clamper together.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above conventional problems, and provides a high-voltage lead wire clamper that can secure a predetermined space distance regardless of the shape of an adjacent mating member and the skill of mounting work. It is an object.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, it is formed into a hemispherical shape symmetrically with a flexible insulating resin, and is flexibly connected at one end, and has a locking hole and a locking claw at each of the symmetrically positioned other ends. Along with the formation of the high-voltage lead wire in the center of the hemisphere, a notch introduction part is formed at the same angle from the outer periphery of the insertion hole in the same direction, and the locking hole and the locking claw are engaged. Then, a high voltage lead wire was fitted and held through the introduction part.

[0005]

[Action]

 According to the above configuration, one end of the hemisphere is birefringently bent so that it can be bent symmetrically, and one of the other ends symmetrically located has a locking claw and the other has a locking hole. The insertion hole for inserting the high-voltage lead wire in the core and the high-voltage lead wire clamper, which has a notch at a predetermined angle in the same direction from the outer periphery of the insertion hole, are bent to bend the locking claw and the locking hole. By engaging them, fitting them into the predetermined part of the high-voltage lead wire from the introduction part and gripping them in the insertion hole, it is possible to secure the space distance between the high-voltage lead wire and the adjacent member to be at least the radius of the sphere, The high-voltage lead wire can be reliably supported regardless of the skill of the work of mounting the high-voltage lead wire clamper or the shape of the adjacent members.

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a side view of an essential part showing a mounting state of a high voltage lead wire clamper of the present invention and an exploded plan view of the high voltage lead wire clamper. As shown in FIG. 1A, a CRT tube 1 such as an OA device is shown. When the high voltage lead wire 3 drawn out from the anode cap 2 is close to the protruding portion of the housing 4, the high voltage lead wire clamper 5 of the present invention is inserted into the portion of the high voltage lead wire 3 close to the protruding portion. By gripping, a space distance equal to or larger than the radius of the high voltage lead wire clamper 5 can be secured between the high voltage lead wire 3 and the protruding portion.

The high-voltage lead wire clamper 5 is molded from a flexible resin such as polypropylene resin, and has a hemispherical shape with one end bendably connected to the connection end 6 as shown in FIG. 1B. A locking claw 7 is formed on one side of the other end at a symmetrical position, and a locking hole 8 is formed on the other side, and an insertion hole 9 for inserting the high-voltage lead wire 3 is formed in the center of the hemisphere and both hemispheres from the outer periphery of the insertion hole 9. The introduction portion 10 is formed by cutting out a spherical surface at a predetermined angle in the same direction, and the locking claw 7 is inserted into the bending locking hole 8 at the connecting end 6 and locked to form a spherical shape.

In this state, the high voltage lead wire 3 is inserted from the introduction portion 10 across the high voltage lead wire 3, so that the high voltage lead wire 3 is held at the center of the spherical high voltage lead wire clamper 5. Further, a second hole 11 having the same diameter as the insertion hole 9 is formed below the insertion hole 9 so as to be overlapped at a predetermined interval, and the introduction portion 10 having a predetermined angle is formed from the second hole 11 by When the high-voltage lead wire 3 is inserted, while passing through the second hole 11 and applying force, the high-voltage lead wire 3 is passed over the projection 12 formed by the insertion hole 9 and the second hole 11 to enter the insertion hole 9, and a voltage higher than that of the projection 12 is applied. The lead wire 3 can be held so as not to fall off.

[0009]

[Effect of device]

 As described above, according to the present invention, when the high voltage lead wire is held at a certain space distance from other members, the high voltage lead wire clamper spherically assembled at a predetermined position of the high voltage lead wire. By mounting and gripping, it is possible to secure a predetermined space distance regardless of the skill of the mounting work.
