BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a complete fitting connector for use in automobiles and the like, in which a pin side connector and a socket side connector are fitted to each other to obtain an electrical connection.

[0002]

2. Description of the Related Art A conventional connector is shown in FIGS.
As shown in FIG. 0 (B) and FIG. 11, in an automobile assembly line or the like, an operator fits a connector having a cable harness. This connector is a pin side connector 21 incorporating a plurality of conductive pin contacts 18.
And a plurality of socket side connectors 23, 24, 25 incorporating a plurality of conductive socket contacts 19. The pin side connector 21 is provided with fitting holes 21a, 21b, 21c for fitting the plurality of socket side connectors 23, 24, 25 in a one-to-one manner on one mating surface thereof. Contact portions 18a of the pin contacts 18 are provided in these fitting holes 21a, 21b, 21c.

A double lock bar 22 is provided on the upper surface of the pin side connector 21. Double lock bar 22
There are formed a pair of locking portions 26a, 26b that lock one-to-one with the pair of locking portions 27a, 27b formed in the fitting holes 21a, 21b, 21c. Further, when the socket side connectors 23, 24, 25 are fitted to the pin side connector 21 in the double lock bar 22, the socket side connectors 23, 24, 25 are fitted in the fitting holes 21a, 21b, 21c.
A plurality of locking portions 28, 2 which are locked in the state of being fitted to the
9 and 30 are formed. Bands 31 connected to the upper surface of the pin side connector 21 are provided on both sides of the double lock bar 22. The band 31 has elasticity so that the double lock bar 22 can be pushed in the upper surface direction of the pin side connector 21 or returned to its original position. A cable 32 is connected to the socket contact 19.

As shown in FIG. 11, when the socket side connectors 23, 24, 25 are fitted into the fitting holes 21a, 21b, 21c, respectively, and then the double lock bar 22 is pushed down, the double lock bar 22 is pushed. The locking portions 26a and 26b and the locking portions 27a and 27b of the pin side connector 21 are locked to each other. Thus, the double lock bar 22 is connected to the pin side connector 2
When locked to No. 1, it is in a completely fitted state as shown in FIG. At this time, the locking portions 28, 29, 30 of the double lock bar
Is the locking portions 30a, 30b, 3 of the socket side connector 25.
It is inserted into a recess formed in the rear part of 0c to prevent the socket side connectors 23, 24, 25 from being pulled out.

However, as shown in FIG. 12, when the connector is half-fitted, the locking portions 28, 2 of the double lock bar 22 are connected.
Any one of 9 and 30 hits the upper part of the corresponding portion of any of the locking portions 30a, 30b and 30c of the socket side connector 25. Therefore, the locking portion 28 of the double lock bar 22,
29, 30 and the locking portion 27 inside the pin side connector 21
The double lock bar 22 cannot be pushed down to the position where a and 27b are locked. In such a half-fitted state, the pin side connector 21 and the socket side connector 2
Although not completely locked with 3, 24 and 25, there is a part where the pin contact 18 and the socket contact 19 are electrically connected. In this way, when the connector is half-fitted, the state is completely different from the fully-fitted state, so that the worker can detect the incompletely-fitted state if he is careful.

[0006]

However, in practice, a worker may misunderstand an incompletely fitted state and incorporate a half-fitted connector into a product such as an automobile as a fully-fitted connector as it is. There are many cases. Moreover, since there is a provisional electrical connection even with half-fitting as described above, it is impossible to detect this even if an electrical continuity test or the like is performed at this point. Then, after the product is put on the market, the pin side connector 21 and the socket side connectors 23, 24, 2 are subject to vibrations or the like.
5 is disconnected and electrical connection is lost, and the product loses the function of the electrical system.

In addition, in the case of the above-mentioned connector,
Since stress is applied to the thin band 31 when the double lock bar 22 is pushed down, the band 3 is repeatedly used.
1 is often damaged. Further, since the double lock bar 22 is integrated with the pin side connector 21, it is difficult to distinguish the locked state of the double lock bar 22. Further, when mating, the pin side connector 21 is replaced with the socket side connectors 23, 2
There are many problems such as the extra work of pushing down the double lock bar 22 as well as inserting into the connector 4 and 25. Therefore, the problem of the invention consists of the pin side connector and the socket side connector. It is intended to improve the certainty of fitting, workability, and durability against repeated use in a connector.

[0008]

According to the present invention, there is provided a connector having a conductive contact and a mating connector having a conductive mating contact in contact with the contact. In a complete fitting connector for mating the mating connectors with each other to obtain electrical contact, the connector includes a plate slidable in the fitting / disengaging direction, and a spring urging the plate in the disengaging direction. The mating connector has a lock lever that slides the plate in the fitting direction, the lock lever has an abutting portion that abuts the plate in the fitting direction, and the connector when fully fitted. And a second engaging portion that engages with the first engaging portion formed in 1.

Further, according to the present invention, the lock lever is bent while abutting on the connector at the time of fitting operation, and the second locking portion is locked to the first locking portion at the time of complete fitting. Then, the complete fitting connector is obtained which is restored to release the abutting portion from the abutting state against the plate.

Further, according to the present invention, the repulsive force of the spring when the contact and the mating contact are in full contact is set to be larger than the pulling force of the mating connector in the complete contact state. A fully mated connector is obtained.

[0011]

When the mating connector and the mating connector are inserted into the connector, the plate provided on the connector abuts against the abutment portion of the lock lever of the mating connector, and the plate is pushed by the mating connector and slides while receiving the repulsive force of the spring. . If the mating operation is stopped while the mating is still performed, the repulsive force of the spring separates the connector from the mating connector.
However, when it is inserted until it is completely fitted, the second locking part on the lock lever of the mating connector engages with the first locking part of the connector, and the plate comes off from the abutting part of the lock lever. Return to the original position and complete mating condition is achieved.

[0012]

1 (A) and 1 (B) show an embodiment of a completely mating connector of the present invention. FIG. 1A and FIG.
Referring to (B), the complete fitting connector has a pin side connector (connector) 1 and a socket side connector (counterpart connector) 2. The pin side connector 1 is shown in FIG.
As shown in FIGS. 2A and 2B, the pin side insulator 11 and the conductive pin contact 18 incorporated in the pin side insulator 11 are included. The pin-side insulator 11 has a large fitting hole 1b formed in the one fitting surface 1a. The socket side connector 2 is fitted in the fitting hole 1b. Pin side insulator 11
A plate 3 slidable in the fitting / removing direction and a pair of coil springs 4 are incorporated therein.

Further, one plate portion (top plate portion) of the pair of plate portions of the pin side insulator 11 which extends in the fitting hole 1b at right angles to the fitting surface 1a and parallel to the fitting direction.
A pair of guide frames 1c are formed on the. Guide frame 1c
Extend in the mating direction. A guide groove 1d is formed on each of the facing surfaces of these guide frames 1c. An accommodation hole 1e for accommodating the pair of coil springs 4 is formed in a rear portion of the top plate portion where the guide frame 1c is formed. The coil spring 4 is provided with a shaft portion 1f in each of the accommodation holes 1e in parallel with the fitting surface 1a. The winding portion 4a in the central portion of the coil spring 4 is fitted to the shaft portion 1f.

The plate 3 has a pair of arm pieces 3a which are parallel to each other and a connecting portion 3b which connects one end sides of the arm pieces 3a. A guide piece 3c is formed at an intermediate portion of the arm piece 3a so as to cut and raise the arm pieces 3a and fit into the guide groove 1d of the guide frame 1c. Further, a hooking piece 3d cut and raised so as to engage with one end of the coil spring 4 is formed at a connecting portion between the arm piece 3a and the connecting portion 3b. Further, a locking piece 9 that locks with a plate locking portion 11a formed at the bottom of the accommodation hole 1e of the pin side insulator 11 is formed in the central portion of the connecting portion 3b. The locking piece 9 is constantly urged toward the fitting surface 1a by the pair of coil springs 4 to prevent the plate 3 from coming out of the pin side insulator 11. The manner in which the coil spring 4 and the plate 3 are installed on the pin side insulator 11 is also shown in detail in FIG.

A first locking portion 6 projecting toward the fitting hole 1b is formed in the top plate inside portion of the pin side insulator 11 between the guide frames 1c. The first locking portion 6 is located near the fitting surface 1a. On the other hand, the socket side connector 2 shown in FIGS. 1 (B), 3 (A) and 3 (B) is a socket side insulator 12 and a plurality of conductive sockets incorporated in the socket side insulator 12. And a contact 19. The socket contacts 19a are in contact with the contact portions 18a of the plurality of pin contacts 18 arranged in the fitting holes 1b of the pin side insulator 11 in a one-to-one correspondence.
And a holding portion 19b connected to these socket portions 19a
And a connection portion 19c. The holding portion 19b is held by the socket-side insulator 12, and the connection portion 19c is connected to the cable 32 into which the socket-side insulator 12 is introduced. In addition, the pin contact 18 has a holding portion 18b, which is provided continuously with the contact portion 18a, and a terminal portion 18c. The holding portion 18b is held by the socket-side insulator 12, and the terminal portion 18c extends outside the socket-side insulator 12 and is connected to a board (not shown) such as a printed circuit board by soldering.

The socket side insulator 12 is formed with a lock bar 10 which can be pushed down on the upper surface corresponding to the guard frame 1c when fitted. On the upper surface of the lock bar 10, a second locking portion 5 that engages with the first locking portion 6 of the pin side insulator 12 at an intermediate portion in the fitting direction, and the second locking portion 5 is provided.
An abutting portion 8 that engages with the tip end portion 7 of the plate 3 is formed on the surface opposite to the locking portion 5 of FIG. That is, the lock lever 10 is connected to the top plate portion 12a including the upper surface of the socket-side insulator 12, and has an elastic restoring force such that the lock lever 10 can be pushed in a direction parallel to the fitting surface 2a.

Next, the fitting operation of the above-described complete fitting connector will be described. The mating surface 1a of the pin side connector 1 and the mating surface 2a of the socket side connector 2 are opposed to each other, and the mating hole 1b
Insert the socket side connector 2 into and fit them. At this time, since the second locking portion 5 has an inclined surface, when the lock lever 10 is inserted with a little strong force, the lock lever 10 is slightly bent downward to start the insertion. If the insertion is continued in this state, the second locking portion 5 provided on the lock lever 10 advances to the second locking portion 6. In this state, the abutting portion 8 formed on the lower side of the tip of the lock lever 1 has the arm piece 3a.
The plate 3 starts to slide in the fitting direction, as shown in FIG.

As the socket side connector 2 is further inserted in the fitting direction, the first locking portion 5 is locked by the second locking portion 6 and the lock bar 10 bent downward is itself. The spring property returns to the original state, and the tip end portion 7 of the arm piece 3a comes off the abutting portion 8. Then, the plate 3 returns to its original position by the repulsive force of the coil spring 4, and the connector is moved to the position shown in FIG.
The completely fitted state is as shown in (A) and FIG. 4 (B).

When the connector in the fitted state is to be disengaged, the lock bar 10 is manually depressed as shown in FIG. Then, the second locking portion 5 is disengaged from the first locking portion 6 of the pin side connector, so that the socket side connector 2 is pulled out from the pin side connector 1. At this time, the plate 3 is bent by pressing the lock bar 10,
If it is set within the range of elastic deformation, it will elastically return to the original state after complete detachment, so there is no problem.

If the fitting operation is stopped before such a complete fitting state is achieved, then FIGS. 7 (A) and 7 (B)
The semi-fitted state is as shown in. That is, the tip portion 7 of the arm piece 3 a remains in a state of abutting against the abutting portion 8 of the lock bar 10. Moreover, since the repulsive force of the coil spring 4 pushes back the plate 3, the entire socket side connector 2 is pushed back in the disengagement direction, separated from the pin side connector 1, and is in a completely unfit state.

That is, according to the present invention, the pin side connector 1 and the socket side connector 2 which constitute the connector are
It will only take one of two states: complete separation or complete mating.

By the way, the coil spring 4 having the above structure
Is set as shown in FIG. In FIG.
a: Complete fitting state, b ₁ ; Complete contact state between pin side contact 18 and socket side contact 19 (state of contact withdrawing force value), b ₂ ; Contact start state between pin side contact 18 and socket side contact 19 (Condition with possibility of conduction), c; b shows the repulsive force of the coil spring 4 at point ₁ .

That is, the repulsive force of the coil spring 4 in the state where the pin side contact 18 and the socket side contact 19 are in complete contact is defined as c, and the withdrawal force of the socket side connector 2 in the complete contact state (force in the complete contact state) When c is d, c> d. In other words, even when the pin contact 18 and the socket contact 19 are in the complete contact state, the second locking portion 5 of the lock bar 10 is completely fitted to the first locking portion 6 of the pin side connector 1. If the combined state is not achieved, the force of the coil spring 4 restores the state in which there is no electrical connection in which the coil spring 4 is not fitted at all.

[0024]

According to the present invention, since the pin side connector and the socket side connector constituting the connector can take only one of two states, that is, they are completely separated or completely fitted, The condition of half-fitting disappears. The lock bar is pushed down when it is inserted, but it has durability against repeated use because there is no thin band. Further, since it is not necessary to manually operate the lock lever at the time of fitting, workability is improved.
