Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ζ connector equipped with a locking mechanism for confirming the complete insertion and fitting state of a socket connector to a pin connector.

``Background'' The second conductor is connected to the pin connector to which the first conductor is attached.
The socket connector with the conductor wires inserted is mated,
A connector is used in which the first and second contacts of the first and second conductive wires are electrically connected to each other by this fitting.

Fig. 1 shows a cross-sectional view of the configuration of the pin connector 11 and the socket connector 12, and Fig. 2 shows the fitted state of the connector. It is in the form of In this scene complete lock, there is a protrusion 13 formed on the upper plate surface of the pin connector 11 on the side opposite to the opening surface, and a protrusion 13 on the insertion side of the connector 12 that is inserted from the opening surface of the pin connector 11. The engaging piece 14 formed on the upper plate surface of the end portion elastically engages with the engaging piece 14 as shown in FIG. 2 when fitted.

Similarly, the configurations shown in FIGS. 3 and 4, respectively, are of a type called an inner cantilever type lock of this type of connector that has been used in the past. In this cantilever lock, there is a protrusion 13 formed on the upper plate surface of the opening side of the connector 11, and a retaining piece 13 formed on the upper plate surface of the socket connector 12 inserted from this opening surface. The piece 14 is configured to be elastically engaged with the piece 14.

For example, connectors of this type used in vehicles have been significantly miniaturized as the number of wiring has increased. However, with such a connector, it is still difficult to check whether a complete connection has been made or not by checking the clicking sensation or the click when the protruding piece 13 and the engaging piece 14 are engaged, as shown in FIGS. 1 to 4 during installation. This is done by wearing sweat.

Confirmation based on this click feeling or attachment sound generally becomes less clear as the connector becomes smaller.

In addition, since this type of conventionally used connector utilizes the elasticity of the material, the elastic force may stop the fitting during the fitting process, resulting in incomplete fitting. On the other hand, it has been proven that these methods of confirming the connection using a click feel or sound are not completely reliable, as they are highly dependent on the environmental conditions in which the judge is placed, even from an ergonomic point of view. ing.

The present invention solves the above-mentioned difficulties in such connectors, especially in this type of connector that requires miniaturization, and makes it possible to easily confirm that the socket connector has been completely inserted into the bin connector. In addition, the present invention provides a connector which can be constructed in an integrated and compact manner without requiring any special parts, and which has a robust structure.

"Summary of the Invention" A connector to which this invention is applied has a configuration in which a bin connector and a socket connector are removably fitted together, and when the fitting is done, the first connector attached to the bin connector is
The first contact of the conductor and the corresponding one of the second 4KfJ contacts attached to the socket connector are electrically connected, respectively. In addition, in this invention, when the bin connector, the lid, and the socket connector are properly fitted, the through hole is formed so that the first plate surface of the bin connector and the second plate surface of the socket connector, which are opposite to each other, are separated by 1 m. It is formed.

On the other hand, a lock piece is rotatably attached to one end of the pin or socket connector. When the lock piece is rotated, a protrusion is formed opposite to the first plate surface, and when the lock piece is rotated to its terminal position when the Binkoi lid and the Sogetsu connector are properly fitted, , the protrusion is configured to be inserted into the through hole.

Therefore, in this invention, the lock piece is rotated to the terminal position only when the sogeto connector is completely attached to the bin connector in a properly fitted state, and the protrusion of the lock piece is inserted into the through hole of the first and second pins. It should be possible to lock the connector by installing it through the board surface.

"Example" Hereinafter, the locking mechanism of the connector of the present invention will be explained in detail based on the example using the drawings.

FIG. 5 is a perspective view showing the construction of an embodiment of the connector locking mechanism of the present invention. The bin connector 11 is made of, for example, a synthetic resin material and is formed into a substantially rectangular cylindrical shape.

The bin connector 11 has a first conductor 13-1.1.3-2.
A first cog tact (not shown) is provided at the end of the first conductive wire located inside the bin connector 1.

The socket connector 12, which is inserted and fitted from the cylindrical opening side of the bottle connector 11, is similarly formed, for example, from synthetic resin into a substantially rectangular parallelepiped shape. A second conductor 1.4-1.14-2 extends through the socket connector 12, the end of which is located within the socket connector 1. A second contact can be made.

When the connector 12 is fitted to the bin connector 1, the first contact of the first conductor 13-1, 13-2 is connected! . . . and second conductive wire 14-1. ．． The corresponding ones of the second contacts of 14-2 are respectively fitted and connected, and the first
conductor 13-1, 13-2 and second conductor 14-'1.
1.4-2 are electrically connected to each other.

The first plate surfaces 21 of the pin connector 11 that face each other when the pin connector 11 and the socket connector 12 are fitted together.
and within the second plate surface 22 of the socket connector 12,
Through holes are formed through the first and second plate surfaces 21 and 22.

That is, the first hole 23 is inserted into the tenth plate 21 of the pin connector 11.
is formed, and a second hole 24 is formed in the second plate surface 22 of the socket connector 12. The first hole 23 is formed through the first plate surface 21, and the second hole 24 is formed through the second plate surface 21.
2 to a predetermined depth. First and second holes 23
．． 24 is formed in almost the same shape, and the pin connector 1
1, the first and second holes 23, 24 are configured to overlap in a normal mated state in which the socket connector 12 is fully attached to the socket connector 12.

A locking piece 25 is rotatably attached to either the pin connector 11 or the socket connector 12, which is the pin connector 11 in the embodiment.

That is, in the embodiment, the lock piece 25 is rotatably attached to one edge of the pin connector 11 in the longitudinal direction around the hinge portion 26 . Hinge portion 26 of lock piece 25
The end portion in the direction away from the plate surface is bent in the direction of the first plate surface 21 at right angles to the plate surface, and an engaging pawl 27 is formed at the bent end portion. A protrusion 28 is formed on the lock piece 25 so as to protrude from a plate surface that faces the first plate surface 21 of the pin connector 11 in a rotated state.

This protrusion 28 has a cross-sectional shape of the first and second holes 23°24.
It is said to be similar in shape to, but slightly smaller in shape. Further, the protrusion length of the protrusion 28 is set to be slightly shorter than the depth of the through hole formed when the first and second holes 23 and 24 overlap. The distance between the side edge of the pin connector 11 to which the O22 piece 25 is rotatably attached and the inner surface of the bent part of the lock piece 25 is slightly larger than the width of the first plate surface 21 in the direction perpendicular to the connector attachment/detachment direction. It is set large and can be locked by rotation. Further, as the lock piece 250 rotates, a retaining groove 31 is formed in one plate i/7730 of the pin connector 11 facing the bent portion of the lock piece 25 over the entire length in the connector attachment/detachment direction. This retaining groove 31 may be formed in a part of the connector in the attachment/detachment direction.

In this invention, when the pin connector 11 and the socket connector 2 are properly fitted, the first and second holes 2
3.24 are overlapped. In this state, the lock 1125 can be rotated around the hinge portion 26 to its final position, and the rotation of the r-socket 425 causes the protrusion 28 to be formed by overlapping the first and second holes 23 and 24. be inserted into the through hole.

By this insertion, the protrusion 28 passes through the second plate 1nj2 of the pin connector 11 and is inserted into the second hole 24 formed in the second plate i/ii 22 of the socket connector 12. , the connector J2 is locked with the pin connector 11 by the protrusion 28. In this case, the lock piece 25 is rotated to the end position 1] and the lock piece 25 is engaged. The mating claw 27 engages with the engagement groove 31 of the pin connector 11, and the pin connector 11 and the socket connector are completely locked.

If the socket connector 12 is not completely attached to the pin connector 11 and is not properly fitted, the first hole 23 and the second hole 24 will be misaligned. Therefore, in this state, the hole diameter of the through hole is effectively reduced, and even if the lock piece 25 is rotated, the protrusion 28 is not inserted into the through hole. It is not possible to lock with.

As described above, in the connector locking mechanism of the present invention, the lock piece 25 cannot be completely rotated unless the pin connector 11 and the socket connector 12 are in a proper mating state, which prevents incomplete mating accidents. can be confirmed.

The pin connectors 11 and connectors 12 are significantly miniaturized by integral molding, and can be easily manufactured with high dimensional accuracy, ensuring complete locking when properly mated. An action is taken.

In the embodiment, a structure in which the lock piece is attached to the bottle connector is described in 1, but a structure in which the lock piece is attached to the socket I/connector is also possible.

As explained in detail above, according to the present invention, it is possible to easily create a device with a significantly reduced shape with high precision, and to easily maintain the proper mating state of a socket connector to a bin connector. A connector locking mechanism that can be checked can be provided.
