Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pair of male and female connector housings equipped with a novel locking mechanism.

Conventionally, many connector housings of this type are molded from synthetic resin or the like, and have a function of preventing disconnection by the fitting contact force of a male connector and a female connector housed and mounted in each housing.

For this reason, accidents such as loosening of the connection or detachment of the housings from each other due to external force may occur.

There are also models that have a locking mechanism between the housings, but due to distortion during molding, deformation and wear due to frequent use, the locking mechanism may not function properly, resulting in incomplete locking. This has caused problems such as poor contact between the connectors and disconnection accidents between the housings.

The present invention was developed to solve the above problem, and locking between the housings is started according to the connection direction of the male and female connectors, but the lock is not retractable in the connection direction and is distantly related. It is an object of the present invention to provide a connector housing equipped with a novel locking mechanism that can achieve a complete locking mode and reliably prevent poor contact between connectors and accidents in which the housings come apart.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

To explain the structure, as shown in FIGS. 1 and 4a, a female connector housing 1 has a plurality of chambers inside for accommodating and mounting multi-pole male connectors. A plate-shaped support 4 is formed integrally with the housing 1.
As shown in FIG. 8, a hook lever 5 and a pressing rod 6 are integrally mounted on the top end along the front end side of the connector housing 1 in a horizontal manner that can swing up and down with the support 4 as a base. Molded.

In this case, in order to facilitate the vertical movement of the hook lever 5 and the pressing rod 6, the connector housing 1, the support column 4, the hook lever 5, and the pressing rod 6 are integrally molded from a flexible synthetic resin material. ing.

Further, the hook lever 5 is formed in a T-shape in which the front part of the band-shaped plate becomes wider in the left-right direction, and a guide 5a having a rectangular vertical section is horizontally protruded from the center of the bottom part. .

Further, on both bottom surfaces of the guide 5a, downward tapered surfaces 5d and 5e are formed at the same angle from the front to the rear, and a vertical surface of a wide portion that connects to the rear end of the tapered surfaces 5d and 5e. For example, the latching surfaces 5f and 5g are formed at a forward tilting angle θ that removes a large amount of the upper end from the lower end.

Further, a pressing rod 6 is formed integrally with the rear end of the hook lever 5, and when the rear end 6a of the pressing rod 6 is pressed downward, the guide 5a and the tapered surface 5d are levered using the support 4 as a fulcrum. , 5e are formed so that the tip of the hook lever swings.

Next, FIG. 2 shows a female connector housing 2, which has a recess at the front into which the front end of the female connector housing 1 can fit, and has a multi-pole female connector accommodated therein. Multiple chambers are formed for this purpose.

In addition, on the left and right positions near the front end of the external upper surface, as shown in FIG. They are each integrally formed in a parallel arrangement, leaving an air space C between them through which the guide 5a of the hook lever 5 described above can pass.

In this case, each tapered surface 3d, 3 of the double-ended body 3A, 3B
e is formed at the same angle as the tapered surfaces 5d and 5e of the hook lever 5 described above, and each tapered surface 3d
, 3e, a surface 3L3g is formed on the rear side angle φ, in which the lower end side is largely removed from the upper end.

The rear angle φ is the same as the forward tilt angle θ described above.

The above constitutes a pair of male and female connector housings.

Next, the action will be explained.

In order to connect the male and female connectors, the female connector housing 1 is connected to the female connector housing 2 as shown in FIG.
When the hook lever 5 is inserted into the front opening from the connecting direction B shown by the arrow, the guide 5a of the hook lever 5 is inserted from the beginning of the insertion.
enters the air space C between the lock bodies 3A and 3B, and at the same time taper surfaces 5d provided on the front left and right sides of the hook lever 5
, 5e move forward as shown in FIG. 5 while slidingly contacting the tapered portions 3d, 3e of the lock bodies 3A, 3B.

Due to the above-mentioned sliding contact, the hook lever 5 moves forward with the front end side lifted from the support 4 as a base point.
When the female connector housing 1 is completely inserted into the opening of the female connector housing 2, the tapered surfaces 5d and 5e of the hook lever 5 engage the locking bodies 3A and 3B.
In order to leave the top end, the hook lever 5 is simultaneously released from the state in which the front end side had been forcibly lifted just before the solenoid, and returns to the horizontal state as shown in FIGS. 7 and 8 due to elastic force.

Therefore, the hook surface 5L5g of the hook lever 5 is the lock body 3A.
, 3B engage with the surfaces 3ft3g, so that the female connector housing 1 and the female connector housing 2 are completely locked.

In addition, the locking surfaces 5f and 5g and the receiving surfaces 3ft and 3g are configured with the same angles θ and φ, and are tilted in the forward direction to deepen the engagement more than a vertical surface, so the locking condition is maintained even when external force is applied. can do.

Next, if you want to unlock the female connector housing 1 and female connector housing 2 after locking them,
When the rear end 6a of the pressing rod 6 is pressed downward, the tip of the hook lever 5 rises in an arc using the support 4 as a fulcrum, so that the lock can be released easily.

Moreover, since the support column 4, which serves as a fulcrum, is located at the center of the entire length and can easily act as a lever, the lock can be released smoothly and easily.

In the above embodiment, the hook lever 5 is provided on the female connector housing 1 side, and the lock body 3A.

3B is provided on the female connector housing 2 side, but the hook lever 5 and the support 4 may be provided on the top surface of the female connector housing 2, and the lock bodies 3A and 3B may be provided on the top surface of the conical connector 1. It can be locked and unlocked in the same way.

As explained above, in the present invention, both the hook lever and the lock body are provided with tapered surfaces that can start locking in accordance with the connection direction of the male and female connectors.
Not only can the housings fit together smoothly, but also when the two housings are fully mated, that is, when the connection between the male and female connectors is completed, the hook lever's latching surface force and the button body's holder are flat. As a result of creating a mechanism that engages the connectors in a non-retractable manner, a complete locking mode is obtained, and it is possible to reliably prevent poor contact between the connectors and accidents of disconnection between the two housings.

Further, when the engagement is to be released, the tip of the hook lever can be easily lifted up using the pillar as a fulcrum by operating the pressing rod and using the lever principle.
