Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector in which contacts to which lead wires are connected are accommodated and locked within a connector housing.

In conventional connectors, a lance is provided protruding from the contact and this lance is engaged with a protrusion of the connector housing, or a lance is provided protruding from the inner surface of the connector housing and this lance is engaged with the protrusion of the connector housing. The contacts are locked to the connector housing by any means of partial engagement.

In order to lock the contact in the connector housing in this way, it is necessary to insert the contact into the connector/) housing to the specified position, but the contact may not be inserted to the specified position, and in this case, external force is applied to the contact. There was a drawback that the contacts would fall off from the connector housing when

In order to improve this problem, a connector as shown in FIG. 1 has been proposed.

This connector has a cylindrical connector housing 1,
The inside of this connector housing 1 is partitioned by a partition plate 2 to form a plurality of contact accommodation chambers 3.

Contacts 5 to which lead wires 4 are connected are inserted and housed in these contact housing chambers 3 from the open end 6 on the lead wire extraction side, and each contact 5 is housed by a contact locking device consisting of a lance, a protrusion, etc. (not shown). Locked inside room 3.

Further, a stopper 7 having a protrusion 7a that is inserted into each contact storage chamber 3 and presses the contact 5 is fitted into the lead wire pull-out side open end 6 to prevent the contact 5 from falling off.

This stopper T is locked to the connector housing 1 by a stopper locking device consisting of a recess (not shown) provided in the connector housing 1 and a protrusion 8 provided on the side surface of this stopper 7.

However, in a connector having such a structure, since the connector housing 1 and the stopper I are separate parts, there is a drawback that the number of parts increases and the cost increases.

In addition, in such a connector, in order to insert the stopper I into the connector housing 1, it is necessary to align each lead wire 4, and in this state, it is necessary to insert the stopper I having a plurality of protrusions 7a. However, there is a disadvantage that the insertion work becomes frequent.

An object of the present invention is to provide a connector that can reduce the number of parts and also allows easy insertion of a stopper without aligning lead wires.

The connector of the present invention has a stopper rotatably supported via a hinge on the side surface of the connector housing, the stopper has a stopper blade inserted into a contact chamber in the connector coupling, and the stopper The blade is characterized in that when the blade is inserted into the contact chamber and positioned, it can come into contact with any part of the rear part of the contact in the normal position, and the blade is inserted into the contact chamber of the stopper blade. If the contact has not yet reached its normal position when inserted, the rotational movement of this stopper blade pushes the contact to its normal position, and also prevents the contact in its normal position from retreating. It is something.

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

FIG. 2 shows a first embodiment of the connector according to the present invention.

The connector of this embodiment has a cylindrical connector housing 1, and the inside of this connector housing 1 is partitioned by a partition plate 2 to form a plurality of contact accommodation chambers 3.

Contacts 5 to which lead wires 4 are connected are inserted into the contact housing chambers 3 from the opening end 6 on the lead wire extraction side and housed therein, and each contact 5 is locked into the contact housing chamber by a contact locking device consisting of a lance and a protrusion (not shown). Locked within 3.

A part of the side wall of the connector housing 1 is omitted to form an opening 8 on the open end 6 side on the lead wire extraction side.

A stopper 9 is provided to close the opening 8, and the stopper 9 is rotatably supported by a hinge 10 at the end of the connector housing 1 near the center.

The stopper 9 has a plurality of stopper blades 9A adjacent to the side wall of the connector housing 1 and the partition plate 2 parallel thereto, which can be inserted into the contact housing chamber 3.

Each stopper blade 9A is positioned in the contact housing chamber 3, and its end surface 9D is positioned at any rear part of the contact 5 in its normal position, for example, the A part of the contact 5 shown in FIG. Contact 5 shown in Figure 3
It is provided so that it can come into contact with the 0B section, etc.

A hook plate 9B is provided on both sides of the stopper 9, and a recess 9C of the hook plate 9B is engaged with a protrusion 11 on the side surface of the connector housing 1, so that the stopper 9 is locked.

That is, the hook plate 9B, the recess 9C, and the protrusion 11 together constitute a stopper lock.

Next, the procedure for assembling such a connector will be explained.

When the contacts 5 with the lead wires 4 are inserted into each contact storage chamber 3 from the open end 6 side of the lead wire pull-out side and pushed into a predetermined position, each contact 5 is locked into contact by a contact locking device (not shown). It is locked inside the storage chamber 3.

Next, the stopper 9 is rotated as shown by the arrow to insert each stopper blade 9A into the corresponding contact housing chamber 3.

In this state, if the contact 5 has reached the normal position and is not locked, the rear part of the contact 5 is pushed by the end surface 9D of the stopper blade 9A due to the rotational insertion operation of the stopper blade 9A, and the contact 5 is It is further pushed into the contact storage chamber 3, reaches the normal position, and is locked.

The stopper 9 is locked to the connector housing 1 by a stopper locking device, and is fixed so as not to be opened except when necessary.

Since the stopper blade 9A is inserted at a position closer to the contact, the stopper blade 9A can be easily inserted without aligning the lead wires 4.

Even if the contacts 5 are not locked due to a failure of the contact locking device, the stopper blade 9A is present at the rear of each contact 5 to prevent the contacts 5 from moving back, so that the contacts can be prevented from falling off. can.

FIG. 4 shows a second embodiment of the connector according to the present invention.

In the connector of this embodiment, the stopper blade 9A is lengthened so that it can be inserted into the upper and lower contact housing chambers 3 in common, and a stopper blade insertion slit 12 is provided in the horizontal partition plate 2 accordingly.

FIG. 5 shows a third embodiment of the connector according to the present invention.

In this embodiment, the connector housing 1 is not opened at the position of the stopper 9, but instead a stopper blade insertion slit 13 is provided in the connector housing 1.

In addition, the connector housing 1 has a temporary stopper 1 for the stopper 9.
There are 4.

By providing the temporary stopper 14 in this way, the stopper 9 will not be bent before the contact 5 is inserted, and the contact 5 can be inserted efficiently.

FIG. 6 shows a fourth embodiment of the connector according to the present invention.

In this embodiment, the temporary stopper 14 is formed of a plastic piece, one end of this plastic piece is integrally connected to the stopper 9, the other end is integrally connected to the connector housing 1, and after the contact 5 is inserted, The temporary fixing can be released by cutting or removing this plastic piece.

As explained above, in the connector according to the present invention, a stopper is rotatably provided on the side surface of the connector housing near the opening end on the lead wire extraction side, and the stopper blade of this stopper is inserted into the contact accommodation chamber from the side surface of the connector housing. Since the stopper blade is inserted into the stopper blade, the stopper blade can be easily inserted without aligning the lead wires, and the efficiency of the assembly work can be improved.

Further, according to the present invention, if the contacts have not yet reached their normal positions when the stopper blade is inserted, the contacts can be pushed to the normal position and locked by the insertion operation of the stopper blade.

Furthermore, when the stopper blade is located at a required position in the contact housing chamber, it is possible to prevent the contact from retreating and to prevent the contact from falling out of the connector housing.
