DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

The connector device with a latch of the present invention is shown in FIG.
As shown in FIG. 3, the connector 1 is provided with a slip-out prevention latch and a latch receiving side connector 2.

The connector 1 with a slip-out preventing latch is a male connector to be inserted into the latch receiving side connector 2. The connector body 3 of the connector 1 with the detachment prevention latch has a detachment prevention latch 4 and a retainer 5 which is paired with the latch 4 to fix the connectors to each other. The latch 4 is formed so as to be inclined so as to protrude outward in the width direction from the body portion of the connector main body 3 in the direction opposite to the insertion direction (shown by a white arrow), and is like a hook. The retainer 5 is provided on the body of the connector body 3 so as to be protruded outward in the width direction at a predetermined interval from the latch 4, and extends linearly in the vertical direction. As the connector 1 with the detachment prevention latch, the same connector as the conventional one can be used.

As shown in FIG. 2, the connector 1 with the slip-out preventing latch has a substantially rectangular column shape with the width A of the connector body 3 and the height B, and the latch 4 is positioned outside the width A of the connector body 3. Out. The distance between the latch 4 and the retainer 5 is C. Further, a modular jack 6 is provided on the front side in the insertion direction, and a terminal to which the twisted pair 7 can be connected is provided on the back side (not shown) as shown in FIG. The connector 1 with the slip-out prevention latch is used for an information outlet.

The latch receiving side connector 2 is a female connector into which the connector 1 with a slip-prevention latch is inserted. As shown in FIG. 3, a plate 8 having a predetermined wall thickness C is provided with an opening 9. Is. The opening 9 is formed to have a width A that is substantially the same as that of the connector main body 3 so that the connector 1 with a latch can be inserted therein and that the connector 4 can be held in contact with the latch 4 to be suppressed. In this embodiment, the opening 9 is cut out at the upper end of the plate 8, so that the latch receiving side connector 2 has a U-shape. The height of the opening 9 is larger than the height B of the connector body 3. Along the both side edges of the opening 9, a latch retainer 10 continuous with the opening 9 is formed on one surface D of the plate 8 by increasing the thickness thereof. The surface D on which the latch retainer 10 is formed is the back surface when the surface E facing the connector 1 with the latch is the front surface. The latch retainer 10 is formed only on the upper portion of the opening 9. At the lower end of the latch retainer 10, a slope 11 inclined outward in the width direction is formed. The latch receiving side connector 2 is used by being fixed to an integrated wiring board or a connection box of the wiring system.

Next, the operation of the embodiment will be described.

FIG. 1A shows how the connectors are connected to each other. The connector 1 with the detachment prevention latch is inserted into the opening 9 of the latch receiving side connector 2 from the direction of the white arrow. While the connector body 3 is passing through the opening 9 of the latch receiving side connector 2, the latch 4 is biased inward in the width direction. FIG. 1B shows a state in which the connection has been completed. After passing through the opening 9, the latch 4 is released on the back side of the opening 9 and returns to its original shape to restrict the movement of the connector body 3 in the direction opposite to the insertion. The latch 4 forms a pair with the retainer 5 to sandwich the latch receiving side connector 2 from the front and back sides,
This secures the connectors to each other. In this way, the connector device with the latch is in a state where it cannot be pulled out. Further, in the present invention, since the slope 11 at the lower end of the latch retainer 10 contacts the latch 4, the upward movement of the connector body 3 is restricted.

In the connector device with a latch according to the present invention, when the connected connectors are to be detached from each other, as shown in FIG.
As shown in (a), the connector body 3 is moved upward. At this time, the latch 4 is guided by the latch retainer 10 while being gradually biased inward in the width direction by the slope 11. As shown in FIG. 4B, when the latch 4 reaches the latch retainer 10, the latch 4 is urged to the width A of the opening 9. Since the latch retainer 10 is continuous with the opening 9, it can be pulled out in the opposite direction to the insertion direction.

Here, when the force Fd for moving the connector body 3 upward is less than the force Fp for urging the latch 4, the upward movement of the connector body 3 is restricted by the latch 4 and the connector body 3 cannot be extracted. The connection is maintained in the state. When the force Fd is greater than or equal to the force Fp, the latch 4 is biased by the latch retainer 10 and is ready for extraction. The force Fp required for detaching the connector can be changed by changing the angle of the slope 11. The steeper the angle of the slope 11, the greater the force Fp and the more difficult it is to remove the connector.

As shown in FIG. 5, a modular jack 12 having a cord can be connected to the modular jack 6 formed in the connector 1 with a latch. Since the direction for inserting / removing the modular plug 12 and the direction for removing the connector are different, the force for removing the connector is unlikely to be generated even if the modular plug 12 is inserted / removed.

Next, another embodiment will be described.

As shown in FIG. 6, the connector device with a latch comprises a connector 61 with a slip-out preventing latch and a latch receiving side connector 62. Unlike the previous embodiment,
The connector 61 with the detachment prevention latch is a female connector, and the latch receiving side connector 62 is a male connector.
That is, the connector 61 with the slip-out prevention latch is the plate 8 provided with the opening 9 having the width A.
Reference numeral 2 denotes a connector body 3, which has a substantially prismatic shape with a width A and a height B, and has a terminal to which a modular jack 6 can be connected on the front side in the insertion direction and a twisted pair 7 can be connected on the rear side.

The upper portion of the opening 9 of the connector 61 with the slip-out preventing latch is open and is larger than the height B of the connector body 3. Latches 6 are provided on the back surface D of the plate 8 on both side edges of the opening 9.
3 are provided. The latch 63 has a predetermined height in the depth direction with respect to the plate 8 and the slope 64 inclined inward in the width direction is formed at the tip of the latch 63. Sticks out.

The latch receiving-side connector 62 has a recess 65 formed in the body of the connector body 3. Dent 65
Is provided at a position where it engages with the latch 63 when the connectors are connected to each other. A slope 66 is formed at the lower end of the recess 65 and is continuous with the body. A presser 67 is provided at a predetermined distance from the recess 65 to form a pair with the latch 63 and fix the connectors to each other.

When the connectors are connected to each other, the latch receiving side connector 62 is inserted into the opening 9 of the connector 61 with the removal preventing latch in the direction of the white arrow. The tip of the connector body 3 contacts the slope 64 of the latch 63, and the latch 63 is biased outward in the width direction. This latch 63 has a recess 6
The connector body 3 is released at 5 to return to its original shape, and restricts the movement of the connector body 3 in the direction opposite to the insertion. The presser 67 restricts the latch receiving side connector 62 from further entering.
This secures the connectors to each other. In this way, the connector device with the latch is in a state where it cannot be pulled out.

When removing the connected connectors,
As shown in FIG. 6B, the connector body 3 is moved upward. At this time, the latch 63 is gradually biased outward in the width direction by the slope 66. When the connector body 3 moves above the latch 63, the connector body 3 is ready to be pulled out in the opposite direction to the insertion direction.

In the connected state, the latch 63 and the recess 6
By the engagement with 5 and the function of the presser 67, the connectors are fixed to each other. At this time, the latch 63 is in contact with the slope 66 of the recess 65, and when a force is applied in the direction of detaching the connector, the slope 66 tries to urge the latch 63 and a repulsive force is exerted. If the force is small, the connector cannot be removed.

[0028]

The present invention exhibits the following excellent effects.

(1) When disconnecting the connectors, a tool or the like is not required, and the connectors can be easily pulled out. Therefore, the work is significantly facilitated and the work time is shortened.

(2) When the direction in which the twisted pair is attached and the direction in which the connector is pulled out are the same, the direction in which the connector is removed is different, so that no load is applied to the twisted pair.

(3) In the connected state, pulling is prevented by the action of the latch, the connected state can be reliably maintained, and when the connectors are detached from each other, the latch can be biased and pulled out only by sliding the connectors. There is an advantage that the removing direction is different from the pulling direction.
