[Industrial applications]

The present invention relates to a retaining structure for an insertion plug that is inserted and connected to a plug receiver.

In recent years, for example, news communication has been performed in which an in-vehicle video transmission radio station is mounted on a vehicle, moved to an arbitrary place, and the device is taken out of the vehicle or transmitted in an in-vehicle state according to the local situation. At that time, it is necessary to promptly place the devices in the transmitting state, the connection cord between the devices can be easily inserted and removed, and it is necessary that the connection cords do not naturally come off after the connection.

However, in many cases, the on-board equipment is configured by combining consumer equipment for economic reasons. Among the connection cords, when the power cord is for consumer use, for example, a two-pole or ground-type two-pole plug is generally used at the end. in use. These plugs can be locked after they are inserted because they are easily removed from the plug receptacle (outlet) due to vibrations, etc. while the car is moving. There is a demand for a retaining structure that can be applied to a plug of a sword.

[Conventional technology]

Conventionally, when the plug of the power cord is not a hook type or a retaining type, for example, a grounding type 2-pole plug, after inserting it into the plug receiver, for example, tie it with wire or attach an adhesive tape and pull it out. I have stopped.

[Problems to be solved by the device]

However, according to the above retaining method, it is troublesome and time consuming to prevent retaining with a wire or an adhesive tape, and there is a problem that economical efficiency is poor because it cannot be repeatedly used depending on the removal.

In view of the above problems, the present invention can be locked after inserting the insertion plug, and can be easily unlocked and inserted, and can be applied to insertion plugs with different insertion heights. It is intended to provide a retaining structure.

[Means for solving the problem]

In order to achieve the above-mentioned object, in the retaining structure of the insertion plug of the present invention, the spring metal wire is bent in a U shape and both ends thereof are used as mounting feet, and the U bent portion is formed into a hook shape. Bending: A pressing spring having an engaging portion that engages with the insertion plug; and a support bolt having a through hole through which the mounting foot is inserted in the shaft center and a push screw screwed to the side surface of the bolt head. In the state where the attachment foot is inserted into and removed from the through hole of the support bolt that is detachably fixed to both sides of the plug receiver, and the engaging portion of the pressing spring presses the insertion plug in the spring, The pressure spring is configured to be locked with a push screw.

[Action]

A metal wire for spring is bent in a U shape, both ends of which are used as mounting legs, and a U-shaped bent portion is formed as a hook-shaped bent engaging portion, and a through hole is formed and a push screw is provided. It is composed of a support bolt, and the support bolt is detachably fixed to both sides of the insertion plug so that the mounting foot of the presser spring can be inserted into and removed from the through hole freely, and the engaging part can spring the insertion plug into the spring. The push plug can be locked while it is pressed to prevent the plug from coming off.

Also, according to the height of the insertion plug, loosen the push screw, adjust the holding spring in and out, and lock it again,
It can accommodate plugs with different insertion heights.

Furthermore, since the presser spring has a spring property, it can be pushed and bent to the side by hand while it is locked, the engaging part can be disengaged to facilitate the insertion plug, and a push screw is provided on the bolt head. Since the threaded portion of the bolt can be freely attached and detached by a nut or the like, it can be easily fixed at any position.

〔Example〕

Hereinafter, the gist of the present invention will be described in detail with reference to the embodiments shown in the drawings.

The retaining structure of the insertion plug is as shown in FIGS. 1 (a) and 1 (b), a side view of a main part and a plan view thereof.
And a support bolt 2 for holding and fixing the pressing spring 1.

The presser spring 1 is made by bending a metal wire rod for spring into a U-shape and using both ends thereof as the mounting legs 1a, and further the U-shaped bent portions are both mounting legs 1a.
It is provided with an engaging portion 1b which is bent into a hooked shape slightly smaller than a right angle with respect to a plane including and is hooked on the upper surface (the upper surface of the cord drawing portion in the figure) of the insertion plug 3 described later. Furthermore, the central portion of the U-shaped bent portion of the engaging portion 1b is recessed in a curved shape by allowing the cord 3a to escape so as to sufficiently engage with the upper surface of the insertion plug 3.

The support bolt 2 has a hexagonal bolt head 2a at its end as shown in a part of FIG.
2b and a bolt head 2a side face is formed with a screw hole 2a-1 toward the axial center, and a push screw 21 screwed into the screw hole 2a-1, for example, a hexagon socket set screw, and a washer 22, A spring washer 23 and a hexagon nut 24 are provided and configured.

The plug 3 is inserted into and removed from the plug receiver 4 mounted on the plug receiver 5 (a mount for collectively mounting the plurality of plug receivers 4) mounted on the mounting plate 6. The mounting plate 6 is provided with burrow holes 5a on both sides of the plug receiver 4 (see FIG. 2), and is inserted into the burrow hole 5a with the support bolt 2 and screwed with hexagonal nuts 24 via washers 22 and spring washers 23. .

In order to prevent the insertion plug 3 inserted into the plug receiver 4 from coming off with the pressing spring 1, the mounting foot 1a is inserted into the through hole 2b of the support bolt 2, and the upper surface of the insertion plug 3 is spring-loaded with the engaging portion 1b. The pressing spring 1 is locked and fixed by the pressing screw 21 in the pressed and engaged state.

When inserting and removing the insertion plug 3, the pressing spring 1 is pushed and bent sideways.

It should be noted that in the embodiment described above, since there are a plurality of plug receivers, they are collectively attached to the plug receiving base, but the plug receiving base may be omitted and the plug receiving bases may be directly attached.
In that case, the wire diameter of the pressing spring is made slightly thin so that the bent engaging portion can be easily removed without plastic deformation.

In this way, using a holding spring and a support bolt with a push screw, the holding spring in which the support bolt is detachably fixed to both sides of the insertion plug is used while the engaging portion is engaged with the upper surface of the insertion plug. By locking, the insertion plug can be locked so that it will not come off via the pressing spring, and it can be bent and bent sideways while the pressing spring is fixed to the support bolt to easily insert and remove the insertion plug. it can. Also, since the height can be adjusted according to the height of the insertion plug / plug receiver by loosening the push screw and inserting / removing the pressing spring, it can be applied to insertion plugs with various different insertion heights. it can.

[Effect of device]

As described above in detail, according to the present invention, the locking work is easier than the conventional wire or adhesive, and the insertion plug can be easily inserted / removed by a simple operation of pushing and bending the pressing spring. . Moreover, it can be applied to plug-in plugs / plug receivers with various insertion heights to reliably prevent disconnection. For example, it can be applied to prevent disconnection of the power cord of a vehicle-mounted video transmission radio station to shorten the device layout. It has an extremely useful effect in practice such that it can be performed in time.
