DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pull-out tab of an L-shaped electrical connector and a connector device having the same.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. 10-12323 discloses a connector of this type which can be easily detached. As shown in FIG. 6 of the accompanying drawings, this connector has a tubular portion 52 in which an external conductor 51 is fitted with a mating connector, and an extending portion 53 extending at right angles to the tubular portion 52. The cable C is held by the extension 53. Therefore, the cable C extends in a direction substantially perpendicular to the fitting direction A of the tubular portion 52 with the mating connector.

When the connector is detached from the mating connector, the tubular portion 52 may be pinched and pulled up in the direction opposite to the direction A. However, for small connectors,
It is not easy to pinch the tubular portion 52. Of course, it is not preferable to pick up the cable C and lift it up. Therefore, in the connector of FIG. 6, a handle 54 is provided above the connector.

[0004] The handle 54 has a narrow band shape, and one end is provided on the outer periphery of the cylindrical portion 52 and fixed by a fixing portion 55.
The other end can be locked with an inverted U-shaped locking portion 56 provided on the extension portion 53. The handle 54 is set to be longer than the distance between the fixing portion 55 and the locking portion 56, and has a projecting protrusion 57 for locking at the other end.

When the connector is disconnected, the handle 54 is gripped and lifted in the direction of arrow B. Handle 54 is overhang 5
7 is bent upward until it locks with the locking portion 56, and it becomes easy to pinch. If you pull up further in this state,
The connector is detached from the mating connector.

[0006]

In the connector shown in FIG. 6, the size of the connector is increased by providing the handle and the members (fixed portion and locking portion) for providing the handle. . This goes against the demand for a low profile connector. Further, the handle and the like complicate the structure and increase the cost. Moreover, the danger of the user pulling the cable directly cannot be avoided.

The present invention solves these problems, has no effect on the height of the connector without complicating the connector, has no risk of the cable being pulled, and has a simple structure and is easy to manufacture. An object of the present invention is to provide a tab that can be attached to an existing connector and a connector device having the same.

[0008]

According to the present invention, there is provided a tubular member for fitting with a mating connector and an extension for holding a cable extending in a direction substantially perpendicular to the axis of the tubular portion. The present invention relates to a pull-out tab for detaching an L-shaped electrical connector having a protrusion from a mating connector and a connector device having the same.

According to the present invention, in the drawing tab of the L-shaped electrical connector, a hole having a peripheral edge portion for engaging with a tubular portion of the L-shaped electrical connector is formed in the flexible band-shaped member.

[0013]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to FIG.
An embodiment of the present invention will be described based on the above.

FIG. 1A is a plan view showing a pull-out tab of the L-type electrical connector, and FIG. 1B is a front view when the tab is attached to the connector. In FIG. 1 (B),
The connector 1 has a tubular portion 2 for fitting with a mating connector C, and an extending portion 4 for holding a cable 3. In the present embodiment, the connector is an example of a coaxial connector, and the tubular portion 2 and the extending portion 4 form an external conductor. The cable 3 has a center conductor connected to a terminal inside the connector, and this terminal is connected to a corresponding terminal of a mating connector. However, this point is not the gist of the present invention. Detailed description is omitted.
A peripheral groove 2A is formed on the lower outer surface of the cylindrical portion 2 of the present embodiment. This is because the cylindrical portion 2 forms an annular portion protruding radially inward in order to ensure the contact with the mating connector, so that a circumferential groove is formed on the outer surface,
Many connectors have this circumferential groove.

In the present embodiment, the pull-out tab 10 is
As shown in FIG. 1A, it is formed by punching a high-strength band-shaped member such as a metal sheet or a plastic sheet.

The pull-out tab 10 has a hole 11 formed at one end thereof.
It is suitable for fitting into the cylindrical portion 2 of the above. Of course,
The inner diameter is such that even if the peripheral portion 11A is larger than the outer diameter of the cylindrical portion 2 and is loosely fitted, and if the outer diameter is slightly smaller than this outer diameter, the peripheral portion 11A is elastically deformed and the cylindrical portion 2A is deformed. It may fit tightly. In the illustrated example, an example in which the peripheral portion 11A is loosely fitted to the tubular portion 2 is shown. The peripheral edge 11A is provided with two locking projections 12 that protrude radially inward. This locking projection 12
Enters into and engages with the circumferential groove 2A of the tubular portion 2 of the connector.

The pull-out tab 10 has a knob 13 at the other end.
Is provided. In this example, the knob 13 has a circular shape. However, the present invention is not limited to this, and the width of the band-shaped member may be simply extended.

Further, a window 14 is formed at an intermediate position of the pull-out tab 10, particularly at a position close to the hole 11. The shape of the window portion 14 is not limited to the rectangular shape shown in the drawing, but it is essential that the extension portion 4 of the connector can be penetrated.
The portion between the window 14 and the hole 11 forms the action portion 15.

FIG. 1 shows a drawing tab 10 having such a structure.
As can be seen in (B), first, the window 1 from the cable 3 side.
4 is inserted through the cable 3 and then
The peripheral edge 11A of the hole 11 is the peripheral groove 2 of the cylindrical portion 2 of the connector.
Set so that it is located at A.

The window portion 14 is provided relatively large so that the window portion 14 of the tab can be pushed open and inserted into the cable 3 through the tubular portion side.
By incorporating in this way, it is possible to easily attach to an existing connector.

When the pull-out tab 10 is not used, the portion from the window portion 14 to the knob portion 13 comes into contact with the cable 3 as shown in a state P shown by a two-dot chain line so as to fit in the housing space of the connector. So that it is located almost horizontally.
This means that, in this state, the height of the connector device does not increase even if the pull-out tab is incorporated, and the portion located above and in contact with the cable 3 covers the cable. This means that there is no danger of picking the cable easily.

When the connector is disconnected, the pull-out tab 1
The pull-out tab 10 is pulled upward so as to change the state from the state P to the state Q by gripping the knob 13 of 0. Then, the action portion 15 of the pull-out tab 10 comes into contact with the extension 4 of the connector 10 from below, and applies an upward pulling force to the extension 4. The portion where the force acts is preferably closer to the axis of the connector because the connector is pulled upward without giving the connector an inclination. Further, since the extension portion 4 is made strong, it can sufficiently withstand the pulling force.

Next, a modified example of the present invention will be described.
The embodiment of FIG. 2 differs from that of FIG. 1 in that the positions of the hole and the window are interchanged and that no locking projection is provided on the periphery of the hole. In such a state, FIG.
As shown in (B), when the cable 3 is passed through the window 14, the knob 13 is located on the side where the cable is absent. By doing so, the knob 13 can be easily picked. in this case,
When the knob 13 is pulled up, the peripheral portion mainly on the left side with respect to the hole 11 lifts the connector, and this forms the action portion 15. Since the periphery of the window 14 is located above the cable 3, it is possible to prevent the cable from being carelessly picked, as in the case of FIG.

The embodiment of FIG. 3 differs from that of FIG. 1 in that there is no window. In this case, when the pull-out tab is not used, the knob 13 is located below the cable,
When used, the knob 1 is slightly rotated around the hole 11 and
3 is pulled out of the cable and raised. The lifting force is transmitted by the peripheral edge 11 </ b> A of the hole 11.

In the embodiment of FIG. 4, a hole 11 is provided at the center and knobs 13 are provided at both ends, and the window 1 is located between them.
4 are formed. Cable is in one of the windows 1
4, when the tab is not used, one half from the hole 11 is located on the cable side, and the other half is located on a straight side extending horizontally without the cable. At the time of pulling up the connector, as shown by the two-dot chain line in FIG.
By doing so, it is possible to pull up strongly, and the pulling force acts straight upward without causing a force to tilt the connector.

Further, in the embodiment of FIG. 5A, two knobs 13 are provided continuously at the center, and the hole 1 is provided at one end.
1 and a window portion 14 is formed on the other end side. This figure 5
Is used by being bent at the center position X. That is, in the bent state, the hole 11 engages with the cylindrical portion 2 of the connector as shown in FIG.
Through the cable. By doing so, the hole 1
The connector is pulled up by the peripheral edge of the window and the peripheral edge of the window.

[0027]

As described above, according to the present invention, since the pull-out tab is formed by processing the strip-shaped member and has a very simple shape, it can be formed at a very low cost. Also, since the connector itself does not require any additional means, it can be immediately attached to an existing connector. Further, the height of the connector device does not increase even if the pull-out tab is incorporated into the connector. In addition, if a part of the pull-out tab is positioned above the cable, there is no danger that the cable is directly picked up and pulled up.
