Description of the Related Art Conventionally, as a mechanism for reducing the operation force of a mating operation or a pulling-out operation with respect to a mating connector, a type in which the structure of a conductive contact itself is devised, or a method of mating or unmating, is employed. Other types are known in which an external force is applied by an additional operation other than the above.

[0003]

Among the above-mentioned conventional connectors, those in which the structure of the contact is devised are less effective even though the structure of the contact is complicated. About 1/2 to 1/4),
Further, the type in which an external force is applied requires a secondary operation other than the fitting and withdrawing, and has a problem that the operation is complicated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector which has a relatively simple structure, uses a normal contact as it is, and does not require any secondary operation other than the fitting and removing operations. It is another object of the present invention to provide a connector capable of reducing the removal operation force.

The third insulator is regulated to move relative to the mating connector during the mating operation with respect to the mating connector, and the amount of movement of the third insulator in the mating direction after the second insulator is mated with the mating connector is determined. Also the first
The connector is characterized in that the first insulator is pushed in the fitting direction by the link by reducing the amount of movement of the insulator in the fitting direction.

Further, according to the present invention, the first insulator is provided in the second insulator and in the second insulator.
Are sequentially incorporated in the third insulator so as to be movable in the fitting direction with respect to the mating connector, and a first pin is protruded from a side surface of the first insulator, and The insulator 2 is formed with a long groove through which the first pin movably penetrates in a certain range in the fitting direction with the mating connector, and a second pin is protrudingly provided on a side surface of the insulator. The insulator has a third pin protruding therefrom. The link has, at one end thereof, a long hole in the longitudinal direction of the link for movably receiving the second pin, and the other end has the third pin. A long hole in the longitudinal direction of the link for movably receiving
Further, pin receiving holes for rotatably receiving the first pin are respectively formed between the two long holes, and a distance between the second pin and the first pin on the link is equal to a distance between the second pin and the second pin. A connector is obtained, wherein the connector is arranged to be smaller than the distance between the third pin.

Further, according to the present invention, the lock member engages with and disengages from the engaging portion of the mating connector in a direction perpendicular to the fitting direction with the mating connector. The third insulator is provided so as to be movable, and the third insulator is moved with respect to the second insulator in the fitting direction with the mating connector.
The connector is characterized in that it is configured to be restrained by the insulator in the engagement state with the engagement receiving portion of the mating connector.

[0008]

According to the present invention, when the second insulator is fitted to the mating connector to the predetermined position during the mating operation with the mating connector, the third insulator is further pushed into the mating connector to the predetermined position. The movement reduces the amount of movement of pushing the first insulator in the fitting direction via the link. Therefore, the principle of leverage acts on the link by the relative movement between the third insulator and the second insulator, and the first insulator can be pushed in the fitting direction with a small force.

Further, during the fitting operation to the mating connector, after the second insulator has been fitted to the mating connector to the predetermined position, the third insulator is further relatively moved and pushed into the mating connector to the predetermined position. When,
The link rotates about the second pin, the third pin acts as a point of force, the second pin acts as a fulcrum, and the first pin acts as a point of action. You can push it. The value obtained by dividing the distance L between the second pin and the third pin on the link by the distance between the second pin and the first pin is the leverage magnification.

Further, at the time of the fitting operation to the mating connector, after the second insulator has been fitted to the mating connector to a predetermined position, the third insulator is further moved relatively and pushed into the mating connector to the predetermined position. When,
A third insulator restrains the lock member and holds the engagement state with the engagement portion of the mating connector.

Referring to FIGS. 1 to 4, the connector 1 on the cable side can be freely fitted and removed from a receptacle 21 as a mating connector in the direction of arrow I shown in FIGS. The connector 1 includes a first insulator 2 having a plurality of conductive contacts 3 and a mating connector 21.
A second insulator 5 having a lock member 6 for preventing the connector 7 from coming off in the fitting direction, and a third insulator 7 which is gripped by hand at the time of fitting to and withdrawing from the mating connector 21.
And The three first, second, and third insulators 2, 5, and 7 are connected to each other by a link 15, and are regulated so as to relatively move in a fixed relationship in the fitting direction.

The first insulator 2 is incorporated in the second insulator 5. Further, the second insulator 5 is incorporated in the third insulator 7. That is, the first, second, and third insulators 2, 5, and 7 are sequentially incorporated in a nesting manner so as to be relatively movable in the fitting direction with respect to the mating connector 21.
The first insulator 2 is formed in a substantially rectangular parallelepiped shape. A first pin 8 protrudes from one side surface of the first insulator 2.

The second insulator 5 has a box shape for receiving the first insulator 2 and has a mating connector 21.
And an opening 9 for receiving the contact 3 and connecting the contact 3. The second insulator 5 is formed with a long groove 10 for movably penetrating the first pin 8 within a certain range in the fitting direction with the mating connector 21, and the second pin 11 is provided in a protruding manner. I have. The lock member 6 is pivotally attached to the first insulator 2 by a shaft 26 at an end in a pull-out direction from the mating connector 21 so as to form a part of both right and left side walls of the second insulator 5. The lock member 6 is urged by the spring 12 so as to be always upright. In the upright state, the engagement portion 13 engages with the concave engagement receiving portion 22 formed on the mating connector 21,
The engaging portion 13 and the engaging receiving portion 22 are detached from each other in the outwardly inclined state.

The third insulator 7 has a box shape for receiving the second insulator 5 and has a third pin 14 protruding from an inner facing portion thereof.

The link 15 is provided inside the third insulator 7 and includes first, second, and third pins 8, 11, and 1.
4 are engaged with each other one by one. That is, link 15
A long hole 16 along the longitudinal direction for receiving the second pin 11 movably at one end, a long hole 17 along the longitudinal direction for movably receiving the third pin 14 at the other end, and A pin receiving hole 18 for rotatably receiving the first pin 8 is provided between the elongated holes 16 and 17. The distance l between the second pin 11 and the first pin 8 on the link 15 is smaller than the distance L between the second pin 11 and the third pin 14, 1 pin 8, 2nd pin 1
The first and third pins 14 are arranged.

FIGS. 5A and 5B are explanatory views of the fitting operation of the connector. The fitting operation of the connector will be described with reference to FIGS. 5 (A) and 5 (B). Now, the third insulator 7 of the connector 1 is grasped, and the distal end of the mating connector 21 is inserted into the opening 9. When the lock member 6 is pushed in such a manner as to be inserted into the second connector 5, the lock member 6 is pushed by the side surface of the mating connector 21 and tilts outward to receive the mating connector 21 in the second insulator 5. The second insulator 5
When the lock member 6 is fitted to the mating connector 21 to a predetermined position, the lock member 6 stands up by the force of the spring 12. At this time, the engagement portion 13 of the lock member 6 engages with the engagement receiving portion 22 of the mating connector 21 as shown in FIG. At this time, the contact 3 of the connector 1 has not been connected to the contact 30 of the mating connector 21 yet. From this state, when the third insulator 7 is further pushed into the mating connector 21 side, as shown in FIG.
Moves relative to the second insulator 5, and the link 15 rotates about the pin 11. By this rotation, the first insulator 2 is pushed out through the pin 8 in the direction of fitting to the mating connector 21, and the contact 3
Are connected to the contacts 30 of the mating connector 21.

In this operation, the third pin 14 is moved to the power point,
This is performed by leverage with the pin 11 as a fulcrum and the first pin 8 as a point of action. In this case, the second on the link 15
The value obtained by dividing the distance L between the first pin 11 and the third pin 14 by the distance 1 between the second pin 11 and the first pin 8 is the leverage magnification. Note that, as shown in FIGS. 5A and 5B, the movement amount b of the insulator 7 at this time is larger than the movement amount a of the insulator 2. When the third insulator 7 is pushed to the predetermined position, the third insulator 7 follows the outer surface of the lock member 6 and prevents the lock member 6 from tilting, that is, unlocking. Unless the third insulator 7 is pulled down, the connector 1 cannot be removed from the mating connector 21.

When the connector 1 is detached from the mating connector 21, the third insulator 7 is pulled down in the withdrawing direction, whereby the lock member 6 is released, and at the same time, the first insulator is actuated by leverage via the link 15. 2 is pulled down and detached from the mating connector 21, and then the second insulator 5 is detached from the mating connector 21. This operation is also performed lightly by leverage.

[0020]

As described above, according to the present invention,
A first insulator provided with a contact, a second insulator having a lock member for preventing the mating connector from coming off in a mating direction, and a third insulator gripping by hand during the mating and unmating operation with the mating connector These three insulators are connected to each other by a link, and are regulated so as to relatively move in a fixed relationship in a fitting direction.
From the amount of movement of the third insulator in the fitting direction after the second insulator is fitted to the mating connector,
Since the amount of movement of the first insulator in the fitting direction is reduced, and the first insulator is pushed in the fitting direction by the link, a normal contact having a relatively simple structure can be used. It can be used as it is, and without secondary operations other than mating and unmating operations,
The operating force for fitting and removing can be reduced.

Also, the first insulator is incorporated in the second insulator, and the second insulator is incorporated in the third insulator so as to be movable in the fitting direction with respect to the mating connector. In the second insulator, a long groove is formed in the second insulator so that the first pin can be movably penetrated in a certain range in a fitting direction with the mating connector, and a second groove is formed on the side surface. A second pin is protruded, a third pin is protruded on the third insulator, and a link has a longitudinal slot at one end side for receiving the second pin movably. A long hole in the longitudinal direction of the link for movably receiving the third pin is formed at the end side, and a pin receiving hole for rotatably receiving the first pin is formed between both long holes, and the second hole on the link is formed. The pin and the first The distance l between the second pin and the third pin is smaller than the distance L between the second pin and the third pin so that the principle of leverage is applied. It is possible to provide a compact connector that is extremely small and has a relatively simple structure.

Further, a locking member is provided movably in a direction orthogonal to a fitting direction to the mating connector in order to engage and disengage with the engaging portion of the mating connector.
When the third insulator is moved in the direction of fitting to the mating connector with respect to the insulator, the third insulator restrains the lock member in an engagement state with the engagement receiving portion of the mating connector. With such a configuration, there is an effect that the operation of restraining and releasing the lock member is interlocked with the operation of fitting and removing the connector, and can be smoothly performed.
