Description

[Detailed Description of the Invention] The present invention relates to a connector, and more specifically, in a connector consisting of a pair of opposing housings having locking means, the locking arm of the connector is prevented from being mated in the opposite direction, and the locking arm is This is to prevent deformation and damage.

For example, in the electrical wiring of automobiles, a connection board having a large number of electrical circuit units inside is used to simplify wiring harness connections.

FIG. 1 shows an example of such a connection board, in which a large number of connector housings 3, 3', 3'', etc. are formed on the outer surface of the connection board 10 case 2, and are connected to internal circuits (not shown). An external connector housing 9 or the like connected to the terminal of the harness W is fitted therein.

These maggots 3, 9, etc. are provided with locking means to prevent them from wobbling or deviating due to vibrations while driving the vehicle.

That is, in the illustrated case, the housing 3 is constructed as a female housing in which two partition walls 4 are used to provide three sleeve portions 5 of the same shape relative to the housing 9, and the outer circumferential wall 6
A locking pawl T having an inclined surface 8 on the upper side is provided in a protruding manner.

On the other hand, the housing 9 is configured as a male housing having a guide groove 10 for the partition wall 4, and a flexible locking arm 12 having a locking hole 13 is provided on the outer peripheral wall 11 thereof.

Therefore, electrical equipment such as the connection board 1 is often installed in a narrow space that is difficult to see from the outside, such as inside the front door of a car, on a dash board, or under a chassis.

Therefore, when fitting the housing 9, the locking arm 12 may be attached in the opposite direction to the housing 3 and left unlocked as shown in FIG. Forcibly attach/detach the locking arm 12.
There were drawbacks such as deformation and damage.

The present invention has been made in order to eliminate such drawbacks.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.
In the figure, reference numeral 14 denotes a housing provided in the case of the connection board 1, and the three housing parts 1 are separated by two partition walls 15.
6 is the same as the housing 3, but
In the present invention, one outer peripheral wall 1γ has an inclined surface 1 on the upper and lower sides.
A locking pawl 18 having a number 9 is provided protrudingly, and a stopper 21 is provided on the outer peripheral wall 20 on the opposite side.

The stopper 21 is provided with an inclined portion 22 or a curved portion at the upper portion thereof that descends toward the outer circumferential wall 20 at a position substantially symmetrical to the locking claw 18 .

Furthermore, an anti-shake wall 23 having a notch 24 is provided around the edge of the outer peripheral wall of the housing 14, facing the locking pawl 18.

Note that the upper end of the stopper 21 is connected to the anti-knock wall 23 and the road surface.
Take it.

In the above configuration, when the external connector housing 9 is fitted into the housing 14, the locking arm 12
The locking pawl 18 engages with the locking hole 13 of the holder and the two are locked.

Furthermore, since the locking claw 18 has an inclined section 19 at the top and bottom, when removing the locking claw 9, the locking arm 12 can be operated with one hand without releasing the locking arm 12 with a finger or the like.

Therefore, when trying to loosely fit the housing 9, the fourth
As shown in the figure, the tip of the locking arm 12 is at the stopper 2.
1 and is prevented from entering the inside of the no-uji puffer fish 14, so loose fitting can be prevented.

In addition, even if the male housing 9 is forcibly inserted in an oblique state when loosely fitting with Therefore, it is possible to prevent troubles such as expansion in the direction of arrow A and damage to the locking arm 12.

In addition, by providing the anti-shake wall 23 continuously on the outer circumferential wall of the housing 14, the work of attaching and removing the housing 9° 14 can be done while maintaining the correct posture, which can prevent the work from happening. .

Although the example in which the bousing 14 is provided on the teeth 2 of the connection board 1 has been described above, the same effect can be obtained when it is applied to an independent component.

As described above, the present invention provides a flexible locking arm having a locking hole on the outer peripheral wall of one of a pair of opposing housings, and a locking claw on the outer peripheral wall of the other housing. , in a connector in which the locking hole of the locking arm and the locking claw are engaged with each other and the locking claw is engaged with the outer periphery of the other door opposite to the locking claw of the other... A stopper is provided on the wall at a position approximately symmetrical to the locking pawl, the upper end of which is located on the outer circumferential wall, and has an inclined or curved portion that descends to the outer circumferential wall. To provide a connector that can be reliably attached and detached even in such a limited space without fitting with the locking arm of the connector in the opposite direction or damaging the locking arm, even by groping.
