Description

  The present invention relates to a connector, specifically a USB connector that can be connected on both sides, where the connector is a concept that includes a plug and a socket that fits into the plug.

In recent years, USB (Universal Serial Bus) is widely used as a common standard for connecting peripheral devices of personal computers such as a keyboard, a mouse, and a printer. In this USB standard, a plug and a socket are defined. Generally, a plug is provided for a peripheral device to be connected to a fixing device, and a socket is provided for the fixing device. There is a connector as a concept including both a plug and a socket.
16A and 16B are side cross-sectional views showing a general USB plug (1) and a USB socket (2). The plug (1) includes a fitting (6) in the plug body (10), and a terminal plate (62) is provided on the fitting (6). In the plug body (10), a first recess (15) is formed above the fitting (6).
The socket (2) includes a first connection piece (3) in the socket body (20), and a first contact terminal (30) is provided on the first connection piece (3). A second recess (26) is formed in the socket body (20) below the first connection piece (3).
When the plug (1) is fitted into the socket (2), the fitting (6) fits into the second recess (26) and the first connection piece (3) fits into the first recess (15), respectively. (62) and the first contact terminal (30) are in contact with each other, and the plug (1) and the socket (2) can be energized. Since the fitting (6) must be correctly fitted in the second recess (26), the mark (55) is placed on one surface of the plug (1) so that the user can correctly recognize the vertical direction of the plug (1). ) Is provided.
However, since the conventional USB plug (1) must be inserted into the socket (2) with the top and bottom (front and back) aligned, for example, when the socket (2) is on the back of a fixed device such as a personal computer. May not be able to see the socket (2) and may not be inserted accurately.
Also, there are card-like plugs that are provided with circuit patterns for USB connection on both sides of the board so that they can be connected regardless of the front and back, but the holding power with the socket is weak.

In view of this point, there has been proposed a socket (2) that can be inserted with the plug (1) facing upward or downward and that maintains the holding force with the plug (1) (see Patent Document 1). 17 (a) and 17 (b) are side sectional views of the socket (2).
In the socket body (20), a second connection piece (4) is provided below the first connection piece (3), and an insulating plate (93) is sandwiched between the second connection piece (4). A second contact terminal (40) facing the first contact terminal (30) is provided. The first and second connecting pieces (3), (4) and the insulating plate (93) are urged toward the plug (1) by the springs (94), (95), (96), respectively, and the housings provided respectively. (97) (98) (99) are in contact with the stopper wall (27) in the socket body (20).
When the plug (1) is inserted from the state shown in FIG. 17 (a), the second connecting piece (4) is pushed against the spring (95) by the fitting (6) and retracts. The housing (98) of the second connection piece (4) pushes the housing (99) of the insulating plate (93) to retract. As shown in FIG. 17 (b), the first contact terminal (30) of the first connection piece (3) and the terminal plate (62) of the fitting (6) are in contact with each other so that the plug (1) and the socket (2) The space can be energized.
When the plug (1) is inserted upside down from the state shown in FIG. 17 (a), the fitting (6) pushes back the first connection piece (3). As a result, the terminal plate (62) and the second contact terminal (40) are in contact with each other, and the plug (1) and the socket (2) can be energized. That is, even if the plug (1) is inserted upside down, the plug (1) and the socket (2) can be energized.

JP 2003-217728 A

In the socket (2) shown in FIGS. 17 (a) and 17 (b), the plug (1) is resisted against the biasing force of the spring (95) while rubbing between the terminal plate (62) and the first contact terminal (30). Advance. Even in the conventional plug (1) shown in FIGS. 16 (a) and 16 (b), the terminal plate (62) and the first contact terminal (30) move forward while rubbing, so FIGS. In the plug (1) shown in FIG. 2), the biasing force (referred to as A) of the spring (95) is applied to the frictional force (referred to as B) between the terminal plate (62) and the first contact terminal (30). It is necessary to push in the plug (1) with sufficient force. Even if the plug (1) is turned upside down, the urging forces of the spring (94) and the spring (95) are equal to A in order to be inserted in the same manner.
In order to prevent the first connecting piece (3) from moving when the plug (1) is inserted, the biasing force A of the spring (94) needs to be larger than the frictional force B. Therefore, the force C required to push the plug (1) is
C = A + B> 2 × B
Therefore, in order to push in the plug (1), a force more than twice that of the previous plug (1) is required, and workability is poor.
Furthermore, since the urging force of the required spring (95) varies depending on the shape of the plug (1), it is expected that a larger insertion force will be required for the plug (1) to be securely fitted into the socket (2). The Further, there is a problem that the spring (95) cannot be confirmed visually even when the urging force of the spring (95) is insufficient and the plug (1) is not securely fitted into the socket (2). Further, since the plug (1) is always urged in the direction pushed by the spring (95), it is considered that the connection between the plug (1) and the socket (2) becomes unstable.
An object of the present invention is to provide a plug and a socket that can be connected even if the front and back sides are reversed and have good workability.

A connector into which a connecting member having a fitting is fitted,
In the connector body (10), connecting pieces (3) and (4) to be pushed by the fittings are arranged side by side and are movable in opposite directions.
A conversion mechanism is provided in the main body (10) to change the retracting operation of one connection piece (3) pushed by the fitting into the protruding operation of the other connection piece (4) from the main body (10). ing.
Further, in the connector main body (20), a connector (8) in contact with the upper or lower surface of the fitting is provided so as to be movable up and down.
The connector (8) has a base end portion having contact terminals (30) and (30) on the upper surface and the lower surface, and is formed thinner than the base end portion, and is located at the approximate center in the thickness direction of the base end portion. With a tip that
In the state where the connecting member is waiting to be inserted, the distal end portion is positioned at a height substantially equal to the upper surface or the lower surface of the fitting.

1. When the connecting member and the connector are not fitted, the connecting member is pushed by the fitting member and the one connecting piece (3) is retracted. Due to the conversion mechanism in the main body (10), the other connection piece (4) protrudes from the main body (10) and comes into contact with the fitting, so that the connection member and the connector can be energized.
That is, regardless of whether the connecting member is facing up or down, that is, the front or back, one connecting piece (3) is retracted by the fitting, and the other connecting piece (4) is projected to contact the fitting. Thereby, the plug or socket which is a connector can be connected even if the front and back are reversed, and the workability is good.
2. In the insertion waiting state of the connecting member having the fitting, the tip of the connector connector (8) is located at substantially the same height as the upper or lower surface of the fitting. When the connecting member is inserted into the connector, the tip of the connector (8) rides on the fitting, and the contact terminals (30) and (30) on the upper or lower surface of the base end of the connector (8) Touches the top or bottom surface. Energization between the connecting member and the connector becomes possible.
That is, this also allows the plug or socket as a connector to be connected even if the front and back are reversed, and the workability when inserting the plug into the socket is good.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As described above, the connector is a concept including both a plug and a socket. That is, any of the following plug (1) or socket (2) may be called a connector.
(First embodiment)
In this example, the plug (1) has a feature. Specifically, the plug (1) can be fitted into the socket even when the top and bottom of the plug (1) are turned upside down. FIG. 1 is an exploded plan view of the plug (1), and FIG. 2 is an exploded side view of the plug (1). In the plug body (10) placed on the substrate (9), there are a first connection piece (3) and a second connection piece (4) located below the first connection piece (3). The two connecting pieces (3) and (4) are slidable in the front-rear direction and move in opposite directions. A first contact terminal (30), which is an elastic body, is attached to the first connection piece (3), and a second contact terminal (40), which is an elastic body, is attached to the second connection piece (4). Flexible circuit boards (31) and (41) that are electrically connected to the board (9) are attached to the boards (30) and (40), respectively.
A pair of rotating gears (5) and (5) are provided opposite to each other on both sides of the plug body (10), and racks meshing with the rotating gear (5) on both connecting pieces (3) and (4). (32) (42) are formed. The rotating gears (5) and (5) are located between the connecting pieces (3) and (4). When one connecting piece (3) slides and retracts into the plug body (10), the rotating gear ( 5) rotates. The other connecting piece (4) slides in a direction protruding from the plug body (10) by the rotation of the rotating gear (5).

First and second guide holes (11) and (12) extending in the front-rear direction are formed on the side surface of the plug body (10), and the first guide hole (11) has a side portion of the first connection piece (3). A spring hook (33) protruding from the plug body (10) is fitted, and a spring receiver (13) is provided at the rear end of the plug body (10). A tension spring (19) is hung on the spring hook (33) and the spring receiver (13). From the side of the second connecting piece (4), a protruding piece (43) protrudes, the protruding piece (43) fits into the second guide hole (12), and the slide is guided.
On the board (9), a connection detection switch (SW1) that is turned on when pressed by any of the connection pieces (3) and (4) is arranged corresponding to the rear end of the plug body (10). Yes. When the connection detection switch (SW1) is OFF, it is determined that the plug (1) and the socket (2) are not connected, and the power supply to the contact terminals (30) and (40) is cut off.

(Mating operation)
3A, 3B, and 3C are side views showing the fitting operation of the plug (1) to the socket (2). For example, the plug (1) is provided in a USB audio device, and the socket (2) is embedded in a wall (100) of a device such as a personal computer, and the plug (1) is fitted into the fixed socket (2). The use of the plug (1) and the socket (2) is not limited to this.
The socket (2) has a known configuration, and a plate-shaped fitting (6) having a terminal (60) is provided in the socket body (20). 3 (a), 3 (b), and 3 (c), it is assumed that the fitting (6) is positioned at the upper end of the socket body (20) and the terminal (60) is disposed downward. With the plug (1) and socket (2) fitted, the terminal (60) contacts either the first contact terminal (30) or the second contact terminal (40), and the plug (1) and socket ( It becomes possible to energize between 2).

Initially, as shown in FIG. 3 (a), the first connection piece (3) is positioned in front of the second connection piece (4), and the second connection piece (4) is connected to the connection detection switch (SW1). Is pushed in.
When the plug (1) is not inserted into the socket (2), the first connection piece (3) in contact with the fitting (6) moves backward as shown in FIG. 3 (b). The first connecting piece (3) is easily retracted by the tension spring (19). The rotary gear (5) meshed with the rack (32) of the first connection piece (3) rotates to push the second connection piece (4) forward. At this time, the second connection piece (4) is disconnected from the connection detection switch (SW1). Energization to both contact terminals (30) and (40) is turned off. While the first connection piece (3) and the second connection piece (4) are sliding in opposite directions, both contact terminals (30) and (40) may be rubbed. If both contact terminals (30) and (40) are energized at this time, the signal that should flow through the socket (2) may flow to the wrong location. In order to prevent this possibility, energization to the contact terminals (30) and (40) is cut off during the sliding movement of both connection pieces (3) and (4).

As shown in FIG. 3 (c), when the insertion of the plug (1) into the socket (2) is completed, the first connection piece (3) pushes the connection detection switch (SW1), and both contact terminals (30) ( Resume energization to 40). The second connection piece (4) is located below the fitting (6), and the terminal (60) and the second contact terminal (40) are in contact with each other. Power is supplied between the plug (1) and the socket (2).
In addition, as shown in FIG. 4, even if the socket (2) is upside down with respect to FIGS. 3 (a), (b), and (c), if the plug (1) is inserted, the second connection piece (4) is pushed, the terminal (60) and the first contact terminal (30) of the first connection piece (3) are brought into contact, and energization between the plug (1) and the socket (2) becomes possible. Of course, even if the plug (1) is turned upside down, it can be inserted into the socket (2).
Further, when the plug (1) with the second connection piece (4) shown in FIG. 4 inserted in the socket (2) with the fitting (6) shown in FIG. The connection pieces (3) and (4) do not slide, but the terminal (60) and the second contact terminal (40) are in contact with each other.

Further, as shown in FIGS. 5 (a) and 5 (b), a protrusion (18) is provided at the front end inside the plug body (10), and the advanced second connection piece (4) is lifted up and the socket (2 ) Of the terminal (60) and the second contact terminal (40) may be increased. In this case, the connecting pieces (3) and (4) slide in opposite directions, and the protrusions (18) push the second connecting pieces (4) while the contact terminals (30) and (40) are facing each other. When lifted, both contact terminals (30) and (40) may be rubbed with a large frictional force, and both contact terminals (30) and (40) may be damaged. Therefore, when the contact state of both contact terminals (30) and (40) is released and the terminal (60) of the socket (2) and the second contact terminal (40) face each other, the protrusion (18) causes the second connection piece. (4) should be lifted.
Of course, the first connecting piece (3) may be pushed down by the protrusion (18).
