[Industrial applications]

 The present invention relates to a connector for connecting a board and a board or a board and a cable by a receptacle-side connection section and a plug-side connection section.

[0002]

[Prior Art]

 FIG. 5 is a side view showing a conventional example of this type of connector, which connects substrates to each other. In the figure, 1 and 2 are substrates, 3 is a receptacle-side connection portion provided on the substrate 1, and 4 is a plug-side connection portion provided on the substrate 2. Reference numerals 5 and 6 are plastic-type housings for covering the connecting portion 3 and the connecting portion 4, respectively.

FIG. 6 is an enlarged side view of an essential part showing only the connecting portion 3 and the connecting portion 4. Both the connecting portion 3 and the connecting portion 4 are made of metal, and the connecting portion 3 has a metal spring. The spring portion 3a is provided with a pressing force depending on the property.

FIG. 7 is a side view showing a connection state of the conventional example, and FIG. 8 is an enlarged side view of essential parts showing a connection state of the connection portions 3 and 4. As shown in the figure, in the conventional example, the contact point is secured by a point or a line by pressing the spring portion 3a, and the connection state is maintained by sandwiching the connecting portion 4 on the plug side by the pressing force of the spring portion 3a. ..

[Problems to be solved by the device]

 However, according to the conventional technique with the above-mentioned configuration, a certain amount of stroke is required because the force of the metal spring is used to secure the contact and holding force of the connector, and therefore, a certain amount of stroke is required, and when connecting the receptacle side and the plug side. There is a limit to reducing the distance. Therefore, there is a problem that an unnecessary height is generated between the substrate and the substrate or between the substrate and the cable, which limits the realization of a small and thin device.

In view of the above problems, the present invention provides a structure that can secure the contact and holding force of the connector without requiring a long stroke, and reduces the distance at the time of connecting the receptacle side and the plug side. The purpose is to realize a smaller and thinner electronic device.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention secures the contact by the pressure from the inside of the contact and holds the pressure.

That is, according to the present invention, in a connector for connecting a board and a board or a board and a cable by means of a connection portion on the receptacle side and a connection portion on the plug side, the connection portion on the receptacle side is embedded in the board and the tip is inward. A protruding hook portion is provided, a press-fitting portion made of conductive rubber is provided at least at the tip of the plug-side connecting portion, and the press-fitting portion is provided on the base side of the press-fitting portion of the connecting portion when the connector is connected. In the state of being press-fitted, a locking portion that abuts on and hooks inside the hook portion on the receptacle side is formed to project.

[0009]

[Action]

 With the above configuration, according to the present invention, when the plug-side connecting portion is inserted into the receptacle-side connecting portion, the press-fitting portion of the plug-side connecting portion made of conductive rubber is compressed and the receptacle-side connecting portion is compressed. It is possible to secure continuity at the contact by pressing. Then, if the press-fitting part of the plug-side connecting part is pressed in until the locking part of the plug-side connecting part enters into the receptacle-side hook part, the force of the press-fitting part trying to restore will cause it to move inside the receptacle-side hook part. The locking portion on the plug side abuts and catches, so that this connection state can be secured.

[0010]

【Example】

 Embodiments will be described below with reference to the drawings. FIG. 1 is a side view showing an embodiment of the present invention, which is a board-to-board connection. In the figure, 1 and 2 are substrates, 10 is a receptacle-side connection portion provided on the substrate 1, and 11 is a plug-side connection portion provided on the substrate 2. Reference numerals 12 and 13 denote plastic-based housings for covering the connection portion 10 and the connection portion 11, respectively.

FIG. 2 is an enlarged side view of an essential part showing only the connecting portion 10 and the connecting portion 11. Here, first, the connection portion 10 on the receptacle side is made of metal and is mounted in the substrate 1 so as to be embedded therein, and a hook portion 10a protruding inward is provided at the tip thereof.

On the other hand, the plug-side connecting portion 11 has a press-fitting portion 11a formed of a conductive rubber at its tip, and the press-fitting portion 11a is press-fitted at the root side of the press-fitting portion 11a when the connector is connected. Then, a locking portion 11b that abuts on and hooks on the inside of the receptacle-side hook portion 10a is formed in a protruding manner.

In this embodiment, the hook portion 10a and the locking portion 11b are made of metal in order to secure more reliable conduction.

FIG. 3 is a side view showing a connection state of the embodiment, and FIG. 4 is an enlarged side view of a main part showing a connection state of the connection portion 10 and the connection portion 11. As shown in the figure, according to the present invention, when the plug-side connecting portion 11 is inserted into the receptacle-side connecting portion 10, the press-fitting portion 11a of the plug-side connecting portion 11 made of conductive rubber is compressed. The connection is secured by pressing against the receptacle-side connecting portion 10 and surface contact of the tip surface of the press-fitting portion.

Then, when the press-fitting portion 11a of the plug-side connecting portion 11 is press-fitted until the locking portion 11b of the plug-side connecting portion 11 enters the inside of the receptacle-side hook portion 10a, the press-fitting portion 11a that is about to be restored is pressed. By the force of, the plug-side locking portion 11b abuts on the inside of the receptacle-side hook portion 10a to be caught, and this connection state is secured.

[0016]

[Effect of the device]

 As described in detail above, according to the present invention, in a connector that connects a board and a board or a board and a cable by a connection portion on the receptacle side and a connection portion on the plug side, the connection portion on the receptacle side is embedded in the board, and A hook part protruding inward is provided at the tip, and a press-fitting part made of conductive rubber is provided at least at the tip of the plug-side connecting part, and at the base side of the press-fitting part of the connecting part, When the connector is connected, since the press-fitting portion is press-fitted, the locking portion that abuts and hooks inside the hook portion on the receptacle side is formed so that the contact is secured by the pressure from the inside of the connection portion on the receptacle side. Can hold pressure.

This makes it possible to secure the contact and holding force of the connector without requiring much stroke, reduce the distance between the receptacle side and the plug side, and realize various electronic devices in a small size and thin shape. There is an effect of doing.

Furthermore, according to the present invention, since the receptacle-side connection portion is embedded in the substrate, the distance between the receptacle-side and plug-side connections can be further reduced, and various electronic devices can be made smaller and thinner. It has the effect of being realized.
