Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a circuit housed in a housing to an external device, and in particular, does not apply excessive force to a connector in the housing fitted to the connector. Moreover, the present invention relates to a connector that can be easily attached and detached.

[0002]

2. Description of the Related Art FIGS. 3 and 4 show examples of a conventional connector for connecting a circuit in a housing to another device. A board-side connector 5 is fixed to a printed board 4 in the housing 1 shown in FIG. The cord 3 for connecting the circuit of the printed circuit board 4 to another device is connected to the connector 6.

[0005] The connector 6 is inserted into the hole 1 a of the housing 1 and fitted to the board-side connector 5 of the printed circuit board 4. When the connector 6 is detached from the board-side connector 5, the lock between the connector 6 and the board-side connector 5 is released by pressing the lock release knob 6a, and the connector 6 can be removed.

The conventional connector described with reference to FIGS. 3 and 4 protrudes greatly from the housing, and is subjected to external pressure. A twist or an inclination easily occurs, and as a result, a stress may be applied to the printed circuit board via the board-side connector 5 and the printed circuit board may be damaged.

A conventional connector shown in FIGS. 5 and 6 will be described. A board-side connector 5 is fixed to a printed board 4 in a housing 1 and is used to connect a circuit on the printed board 4 to another device. Are connected to the connector 6.

The connector 6 is inserted into the hole 1 b of the housing 1 and fitted to the board-side connector 5 of the printed circuit board 4. Hole 1
The b is provided with a recess for operating the lock release knob 6a, and the connector 6 is inserted deep into the housing 1.

When disconnecting the connector 6 from the board-side connector 5, the lock between the connector 6 and the board-side connector 5 is released by putting a finger into the recess of the hole 1 b and pressing the lock release knob 6 a to release the connector 6. Can be.

[0008]

The conventional connectors shown in FIGS. 5 and 6 are hardly subjected to external pressure and have a low possibility of damaging the printed circuit board. However, when the connector is detached from the connector on the board side, the connector is provided in the recess of the hole 1b. It is necessary to insert a finger to push the lock release knob 6a, and there is a problem that it is difficult to remove the connector.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a connector which is free from the possibility of external pressure being applied to a printed board or the like via a board-side connector and which is easy to attach and detach. To provide.

[0010]

A connector according to the present invention comprises:
A connector for connecting a circuit housed in the housing to an external device is connected, inserted into a hole of the housing, and fitted to a connector arranged inside the device. The peripheral edge of the hole of the housing is brought close to the periphery of the connector, and the connector is provided with a stopper that contacts the peripheral edge of the hole.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A connector according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a use state of a connector according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a use state of the connector.

A board-side connector 5 is fixed to a printed board 4 in the housing 1 shown in FIG. The cord 3 for connecting the circuit of the printed circuit board 4 to another device is connected to the connector 2.

The connector 2 is inserted into the hole 1 a of the housing 1 and fitted to the board-side connector 5 of the printed circuit board 4. The hole 1 a of the housing 1 is slightly larger than the outer circumference of the connector 2.
The clearance between the connector and the connector 2 is small. To release the connector 2 from the board-side connector 5, the lock release knob 2a
By pressing, the lock between the connector 2 and the board-side connector 5 is released, and the connector 2 can be removed.

The triangular stoppers 2b, 2b,... Provided on the four sides of the connector 2 are provided with holes 1a of the housing 1 when the connector 2 is fitted to the board side connector 5.
Abut or close to the edge of Therefore, even when an external pressure is applied to the connector 2, the stoppers 2b, 2b,... Are not pressed or contacted with the housing 1 but twisted or tilted, and stress may be applied to the printed circuit board 4 via the board-side connector 5. There is no.

In addition, the connector 2 can be made to protrude from the housing so that the lock release knob 2a is released to release the lock of the connector 2, so that the connector 2 can be easily attached and detached.

Although the embodiment is constructed as described above, the invention is not limited to this. For example, the connector may be formed in a triangular shape or a cylindrical shape instead of a square shape.

The shape of the stopper is not triangular,
Any shape having a surface in contact with the housing may be used.

Further, instead of forming the stopper integrally with the outer surface of the connector, the stopper may be fixed to the outer surface of the connector by press-fitting or bonding.

[0019]

According to the connector of the present invention, the stopper provided on the connector abuts or approaches the edge of the hole of the housing, so that the stopper is pressed against the housing even when external pressure is applied to the connector. There is no twisting or tilting alone, and there is no possibility that stress will be applied to the printed circuit board via the board-side connector.

Moreover, the connector can be largely protruded from the housing so that the lock release knob for releasing the lock of the connector comes out, so that the connector can be easily attached and detached.
