Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a plug-in connecting member which is connected by inserting an end into a connector.

Problems to be Solved by the Related Art and Invention The flexible cable is connected to the connector by inserting its end into the connector until it stops. It is necessary to insert the flexible cable all the way to the inside of the connector, because if the insertion dimension is insufficient, poor contact will occur.

In the actual connection work, the flexible cable may be caught and the insertion may stop halfway. If the flexible cable stops near the inlet of the connector, it can be confirmed that the insertion is insufficient, even if it can be confirmed from the exposed state of the electrode, etc. However, there is a problem in that it is difficult to confirm that the insertion is insufficient, and there is a risk that the poor contact may be overlooked.

Means for Solving the Problems The present invention relates to a board-shaped plug-in connecting member which has a plurality of electrodes arranged side by side along its end and which is connected to the connector by inserting the end from the insertion port side. The state confirmation index is a position behind the electrode when viewed from the end of the insertion connection member itself,
With respect to each of the plurality of electrodes, a configuration is adopted in which, from the end, when the plug-in connection member is normally connected to the connector, the plug-in member is positioned to be inserted into the connector. When the plug is inserted into the connector and connected, the insertion state confirmation index faces the insertion port of the connector.

Function The position of the index with respect to the insertion opening of the connector functions as a guide indicating whether or not the insertion state is normal when the insertion connection member is inserted in the connector.

Embodiment FIG. 1 shows a flexible cable 1 which is an embodiment of a plug connecting member according to the present invention. In the figure, 2 is a flexible substrate, 3 is a plurality of printed wirings on the substrate 2, and 4 is an electrode at the end of each printed wiring 3.

Reference numeral 5 is a line as an insertion state confirmation index, which is formed at a position a from the end of the cable 1 at a dimension a so as to cross the cable 1. The dimension a is a dimension that is inserted into the connector when the cable 1 is inserted into the connector described later and is normally connected.

As shown in FIG. 2 or 3, the flexible cable 1 is inserted into the insertion port 8 of the connector 7 mounted on the printed circuit board 6 in the direction of arrow A until it stops.

When the end of the cable 1 is normally inserted into the inner part of the connector 7, it becomes as shown in FIG. 2 and the line 5 faces the insertion port 8.

When the end of the cable 1 is caught on the way and stopped, the line 5 is as shown in FIG.
I haven't arrived yet.

Therefore, by visually confirming the position of the line 5 with respect to the connector 7, it is possible to determine whether or not the cable 1 is normally connected to the connector 7. Third
In the case of the figure, it is further inserted to obtain the state shown in FIG. As a result, it is possible to guarantee that each connection unit is in a normal connection state.

Moreover, as shown in FIG.
Alternatively, the end 11a of the reinforcing plate 11 provided at the end can be used as an index. That is, the size b of the reinforcing plate 11 is set equal to the size a. As a result, when the cable 10 is normally inserted into the connector 7 as shown in FIG. 2, the end 11a of the reinforcing plate 11 faces the insertion port 8 of the connector 7 and is caught in the middle as shown in FIG. In the case of the end, the end 10a does not reach the insertion port 8. In this way, the end 11a of the reinforcing plate 11 serves as an index indicating the inserted state,
In this case, the line 5 is unnecessary.

Further, the line 5 is not limited to a flexible cable, but may be similarly applied to a printed circuit board (so-called card edge) in which electrodes are arranged at an edge portion and this portion is inserted and connected to a connector. FIG. 5 shows this example.
In the figure, 20 is a printed circuit board, 21 is an electrode, and 22 is a line as an index.

EFFECTS OF THE INVENTION According to the present invention, in the insertion connection member having a plurality of electrodes arranged side by side at the tip in the insertion direction, the insertion state confirmation index is provided at a position rearward of the electrode. It is possible to avoid the disadvantage that the electric connection state of the electrode to the connector is adversely affected by the interference with the.

That is, in the insertion member having the electrode at the tip in the insertion direction, it is possible to confirm the insertion state without adversely affecting the electrical connection between the electrode and the connector.
The reliability of the connection can be improved.

In addition, the insertion state confirmation index is a dimension corresponding to the dimension at which the insertion member is inserted into the connector when the insertion connection member is normally connected to the connector from the end for each of the plurality of electrodes. Since it has a configuration in which it is located at a distant position, it is possible to visually check the index not only when the amount of insertion of the insertion member into the connector is normal, but also when it is insufficient. You can check whether the insertion amount of the insertion connection member is sufficient or insufficient by using the position with respect to the insertion port as a guide, and even if the insertion member is inserted diagonally to the connector, an index Can be visually checked, and the inclination of the visually recognized index with respect to the connector insertion port
It is possible to confirm that the plug-in connection member is inserted into the connector at an angle.

As a result, it is possible to reliably prevent the incompletely inserted state from being overlooked, and it is possible to improve the reliability of the connection.
