Description

Lever-type connector assembly {LEVER-TYPE CONNECTOR ASSEMBLY}

The present invention relates to a connector, and more particularly, to a lever type connector assembly for coupling between two connectors through a lever using the principle of a lever.

In general, a connector assembly coupled to each other is composed of a first connector and a second connector. The first connector and the second connector are coupled to each other so that terminals therein are electrically connected. In this case, as the number of terminals increases, the coupling force required for coupling the first connector and the second connector increases.

In order to generate such a large coupling force, a lever is installed on one connector, and the lever is rotated to apply the principle of a lever to facilitate coupling between the connectors. To this end, the lever is rotatably installed about the rotation axis of the first connector.

Coupling channels are formed on both side surfaces of the first connector. The coupling channel is formed such that one side thereof is opened toward the second connector and serves to guide the coupling protrusion of the second connector.

A guide channel is formed on the inner side of the lever. The guide channel serves to guide the coupling protrusion of the second connector to move along the coupling channel of the first connector. That is, when the second connector is pushed toward the inside of the first connector, the coupling protrusion of the second connector is simultaneously inserted into the guide channel of the lever and the coupling channel of the first connector. This state is defined as a temporary bonded state.

In the temporary coupling state, when the lever is rotated in a direction parallel to the outer surface of the first connector, the coupling protrusion of the second connector is guided along the coupling channel of the first connector, so that the first and second connectors It is completely combined and becomes a completely combined state.

On the other hand, in the temporary coupling state as described above, when the lever is rotated to become fully coupled, the first connector on which the lever is installed and the lever generate a fastening sound, and the first connector and the second connector are fully coupled. Is completed.

However, the prior art as described above has the following problems.

The fastening sound in the fully coupled state is generated by colliding the lever with the first connector on which the lever is installed, and even when the fastening sound occurs, there is a case where the first connector and the second connector are not completely combined. The first connector and the rotation lever generate the fastening sound. Since the rotation lever is installed in the first connector, the first connector and the rotation lever collide even if the first connector and the second connector are not completely coupled. This is because a fastening sound may occur. Accordingly, the operator hears the fastening sound during the assembly process of the first connector and the second connector and knows that the connection is complete, but there is a problem that assembly failures frequently occur due to the fact that the connection is not substantially fastened.

Republic of Korea Utility Model Registration No. 20-0467962

An object of the present invention is to solve the problems of the prior art as described above, and to provide a lever type connector assembly that generates a fastening sound only when a first connector and a second connector are coupled.

A support portion for elastically supporting the sound generating portion is formed on an outer surface of the first connector at a position corresponding to the sound generating portion, and the support portion is elastically deformed together with the sound generating portion and then restored.

The support part is formed to have elasticity in a'b' shape from the outer surface of the first connector, and a support body whose tip extends toward the second connector, and a part of the tip of the support body is a cross section of the support body. It includes a seating end that extends to an area that is relatively smaller than the width, and a seating surface is formed at the front end of the support body in a direction perpendicular to the seating end, and a part of the sound generating unit is seated and supported on the seating end and the seating surface .

The sound generating part is formed to have elasticity in a'b' shape from the outer surface of the second connector, and its tip is formed integrally with an elastic arm extending toward the first connector, and is integrally formed with the tip of the elastic arm. It includes a plate-shaped body supported by an arm and spaced apart from an outer surface of the second connector by a predetermined distance, and the rotation lever hits a lever contact surface forming the outer surface of the body to generate a fastening sound.

A raised portion protrudes from the outer surface of the body in a direction away from the outer surface of the second connector, and when the rotation lever interferes with the raised portion and the interference is released, the rotation lever hits the lever contact surface to generate a fastening sound.

The raised portion includes an inclined inclined surface formed to be inclined toward the lever contact surface from one side of the raised portion, and an engaging inclined surface formed to be inclined from a point where the guided inclined surface ends to the contacting surface of the lever.

The engaging inclined surface forms an acute angle with the lever contact surface.

That is, only when the first connector and the second connector are completely coupled, the rotation lever collides with the sound generating unit to generate a fastening sound. Accordingly, there is an effect of reducing an assembly defect between the first connector and the second connector.

In the present invention, the elastic arm is elastically deformed by the striking surface of the rotating lever that moves while pressing the inclined surface of the ridge formed in the sound generating unit, and when the interference with the inclined surface of the rotating lever is released, the deformation of the elastic arm is released and hitting. The surface collides with the lever contact surface. The striking surface can produce a larger fastening sound by adding the moment generated when the rotating lever rotates and the restoring force, which is a reaction of the force pushing the ridge while deforming the elastic arm. Therefore, there is an effect that the operator can clearly hear the fastening sound even in a noisy work environment.

In addition, since the elastic arm of the sound generating unit is deformed, the support unit is also elastically deformed to support the deformation of the elastic arm, so when the elastic arm is restored, the restoring force of the support unit is also added, so that a larger fastening sound can be produced.

A preferred embodiment of the present invention lever type connector assembly will be described with reference to the drawings.

The lever type connector assembly includes a first connector 10 and a second connector 20 and a rotation lever 30 rotatably installed on the first connector 10.

Referring to FIGS. 1 and 2, a first housing 11 is formed as an exterior of the first connector 10. The first housing 11 has an inner space 11 ′ formed to open one side thereof, and a terminal insertion portion 12 is formed in the inner space 11 ′ toward an inlet of the inner space 11 ′. A plurality of terminals (not shown) are inserted into the rear end of the first connector 10 to be seated in the terminal insertion part 12, and the second connector 20, which is a mating connector, opens the first connector 10. At one side, the terminal is coupled to the terminal insertion part 12 to be electrically connected.

Hinge protrusions 13 protrude symmetrically on both sides of the outer surface of the first housing 11. The hinge protrusion 13 is provided with a rotation lever 30 to be described later, and the rotation lever 30 is rotated using the hinge protrusion 13 as a rotation axis.

Insertion channels 14 are formed on both sides of the outer surface of the first housing 11. When the first connector 10 and the second connector 20 are coupled, the coupling protrusion 22 of the second connector 20 is inserted into the insertion channel 14.

2 and 3, a support part 15 is formed on the first housing 11. The support part 15 is formed on the outer surface of the first housing 11, and the rotation lever 30 Is formed within the radius of rotation. The sound generating part 23 of the second connector 20 to be described later is mounted on the support part 15. As the sound generating unit 23 is elastically deformed, the support unit 15 is also deformed, and when an external force causing elastic deformation to the sound generating unit 23 is released, the sound generating unit 23 and the support unit 15 At the same time, the restoring force acts. The restoring force of the support part 15 is transmitted to the sound generating part 23.

As for the support part 15, the support body 15a forms an exterior. The support body 15a is formed in an approximately'a' shape to have elasticity, and extends toward the second connector 20. As shown in FIG. 3, the support body 15a may be formed in a pair to be symmetrical to each other. However, the present invention is not limited thereto, and the designer may variously change the shape and number of the support body 15a.

A seating end 15b and a seating surface 15c are formed at the front end of the support body 15a. The seating end (15b) is formed extending from the support body (15a). A part of the sound generating unit 23 is mounted on the upper surface of the seating end 15b and supports the sound generating unit 23. It is preferable that the seating end 15b is formed relatively close to the outer surface of the first housing 11 because it can support the sound generating unit 23 more stably.

Since the force acting on the sound generating unit 23 is a combination of forces in several directions, the support body 15a needs to support the sound generating unit 23 on at least two sides. Accordingly, the front end of the support body 15a becomes a seating surface 15c. The seating surface 15c is formed in a direction perpendicular to the seating end 15b. That is, the seating surface 15c is formed to face the direction in which the tip of the support body 15a faces. The seating surface 15c supports the sound generating part 23 like the seating end 15b.

In the first housing 11, a concave inlet 16 is formed at the edge of the inner space 11'. The concave portion 16 is formed at a location corresponding to the position where the support portion 15 is formed. The concave inlet portion 16 accommodates a part of the elastic arm 23b of the sound generating portion 23. The elastic arm 23b is seated in the concave inlet 16 and supports the elastic arm 23b when an external force is applied to the elastic arm 23b.

A lever support 17 is formed adjacent to the support 15 on the outer surface of the first housing 11. The lever support 17 is formed across the first housing 11 in a coupling direction with the second connector 20. A pair of the lever support 17 may be formed, and the support 15 may be positioned therebetween. The lever support 17 is formed adjacent to the support 15 to prevent damage to the support 15 from the outside. In addition, when the first connector 10 and the second connector 20 are coupled, the rotation range of the rotation lever 30 is limited so that the sound generating unit 23 is excessive by the rotation lever 30. To prevent damage due to pressure.

The exterior of the second connector 20 is formed by a second housing 21. Although not shown in the drawings, the front portion of the second housing 21 is formed in a shape corresponding to the terminal insertion portion 12 of the first connector 10.

Engaging protrusions 22 are formed on both sides of the outer surface of the second housing 21. The coupling protrusion 22 is formed at a position corresponding to the insertion channel 14 of the first connector 10.

Referring to FIG. 4, a sound generator 23 is formed in the second housing 21. The sound generating part 23 is formed at a position corresponding to the first support part 15 formed in the first housing 11. The sound generator 23 generates a fastening sound by colliding with the rotation lever 30. The sound generating unit 23 has the body 23a and the elastic arm 23b forming an exterior thereof. On the outer surface of the body 23a, there is a lever contact surface A that collides with the rotation lever 30 to generate a fastening sound. The lever contact surface (A) is located between the raised portion 24 and the elastic arm (23b) to be described later. The elastic arm 23b is formed to have elasticity in an approximately'b' shape from the second housing 21 so that the tip of the elastic arm 23b extends toward the first connector 10. A plate-shaped body 23a is integrally formed at the front end of the elastic arm 23b, and the weight of the body 23a is supported by the elastic arm 23b. Accordingly, the body 23a is spaced apart from the outer surface of the second housing 21.

A close contact arm 23c extends toward the first connector 10 at the edge of the body 23a. The contact arm 23c is seated on the support body 15a when the first connector 10 and the second connector 20 are coupled. Specifically, the contact surface 23d formed at the front end of the contact arm 23c is in contact with the seating surface 15c, and the bottom surface of the contacting arm 23c is in contact with the seating end 15b. The contact arm (23c) is formed to correspond to the number of the support (15). In this embodiment, since two support portions 15 are formed, a pair of the contact arms 23c are also formed on both sides of the body 23a.

A raised portion 24 is formed in the body 23a. The raised portion 24 protrudes in a direction away from the outer surface of the second housing 21 between the pair of contact arms 23c. The raised portion 24 interferes with the rotation lever 30 to elastically deform the elastic arm 23b.

A guide inclined surface 24a and a locking inclined surface 24b are formed on the outer surface of the raised portion 24. The guided inclined surface 24a is formed to be inclined toward the lever contact surface A from one side of the raised portion 24. During the rotation of the rotation lever 30, the raised portion 24 is pressed by the lever body 31. At this time, the lever body 31 presses the raised portion 24 while descending on the guide inclined surface 24a and simultaneously elastically deforms the elastic arm 23b toward the support portion 15. That is, the guided inclined surface 24a serves to guide the lever body 31 so that the elastic arm 23b can be elastically deformed smoothly.

An engaging slope 24b is formed on the raised portion 24 from the point where the guide slope 24a ends to the lever contact surface A. The engaging inclined surface 24b is formed to be inclined toward the center of the raised portion 24 to form an acute angle with the lever contact surface A. This structure is formed to correspond to the shape of the edge of the hitting surface 33 of the lever body 31 to be described later, and when the rotation lever 30 is completely rotated, the edge of the hitting surface 33 is It is accommodated in the space formed by the outer surface of the body (24b) and the body (23a). The engaging inclined surface 24b provides the operator with a sense of separation in which the rotation lever 30 deviates from the raised portion 24 when the hitting surface 33 deviates from the engaging inclined surface 24b.

The rotation lever 30 includes a lever body 31 and a pair of lever arms 32. The pair of lever arms 32 are disposed to face each other, and both ends of the lever body 31 are integrally connected with each of the lever arms 32. The rotation lever 30 is rotatably fitted to the hinge protrusion 13 of the first connector 10 to provide a fastening force required when the first connector 10 and the second connector 20 are coupled.

A striking surface 33 is formed on the lever body 31. When the first connector 10 and the second connector 20 are completely coupled as shown in FIG. 1, the hitting surface 33 is a surface of the lever body 31 facing the first connector 10. It is concave and formed. The hitting surface 33 pressurizes the raised portion 24 to elastically deform the sound generating portion 23, and hits the sound generating portion 23 to generate a fastening sound.

In more detail, when the rotation lever 30 is rotated, the striking surface 33 presses the raised portion 24 and moves along the guided inclined surface 24a. When the hitting surface 33 of the lever body 31 presses the raised portion 24, the elastic arm 23b is also elastically deformed. The support body (15a) is subjected to a pressing force on both the seating end (15b) and the seating surface (15c) and is elastically deformed together with the elastic arm (23b).

When the rotation lever 30 is completely rotated, the contact of the hitting surface 33 with the guided inclined surface 24a is released, so that the hitting surface 33 and the lever contact surface A of the sound generating part 23 are When it hits, a fastening sound is generated. At this time, when the force of the lever body 31 pressing the raised portion 24 disappears, a restoring force acts on the elastic arm 23b of the sound generating portion 23 and the support body 15a of the support portion 15. do. When the restoring force of the elastic arm 23b and the support body 15a and the rotational moment of the rotation lever 30 are added, the hitting surface 33 hits the lever contact surface A of the sound generating unit 23 , It produces a relatively louder fastening sound.

The lever arm 32 is formed adjacent to the hinge protrusion 13 of the first connector 10, and the coupling channel ( 34) is formed. In more detail, the distance between the hinge protrusion 13 and the coupling channel 34 is formed so that the distance between the hinge protrusion 13 and the coupling channel 34 continuously increases from the hinge protrusion 13 to the front end of the lever arm 32. The coupling protrusion 22 of the second connector 20 is inserted into the coupling channel 34. The coupling protrusion 22 moves along the insertion channel 14 in association with the rotation of the rotation lever 30.

Next, a process of generating a fastening sound by combining the first connector 10 and the second connector 20 of the present embodiment will be described.

First, as shown in FIG. 2, the first connector 10 and the second connector 20 are arranged to face each other, and the second connector 20 is moved toward the first connector 10. At this time, the rotation lever 30 is rotatably installed on the first connector 10 with the hinge protrusion 13 as a rotation axis. The first connector 10 is in the insertion channel 14 of the first connector 10. 2 When the coupling protrusion 22 of the connector 20 is inserted and reaches the entrance of the coupling channel 34, the elastic arm 23b of the sound generator 23 is seated on the concave portion 16, and the A pair of contact arms (23c) is supported by the support body (15a). At this time, the coupling state between the first connector 10 and the second connector 20 is referred to as a temporary coupling state.

When the rotation lever 30 is rotated toward the second connector 20 in the temporary coupling state, the coupling channel 34 moves along the coupling protrusion 22 and the second connector 20 is moved to the second connector 20. It is pulled into the inner space 11' of 1 connector 10.

When the rotation lever 30 is completely rotated, the hitting surface 33 hits the lever contact surface (A) to generate a fastening sound, and the first connector 10 and the second connector 20 are completely coupled. It is in a state of complete bonding.

Meanwhile, referring to FIG. 5, the hitting surface 33 of the lever body 31 presses the upper outer surface of the raised portion 24 along the guide inclined surface 24a, and accordingly, the sound generating portion 23 ) And the support part 15 supporting the sound generating part 23 are elastically deformed together.

After the rotation of the rotation lever 30 is completed, the interference between the hitting surface 33 and the guided inclined surface 24a is released as shown in FIG. 6. Accordingly, the sound generating unit 23 and the support unit 15, which have been elastically deformed, are restored in the direction of the respective arrows shown in FIG. 6 and collide with the rotation lever 30 to generate a relatively large fastening sound.

Next, a process in which the first connector 10 and the second connector 20 of the present embodiment are released will be described.

In the fully coupled state of the first connector 10 and the second connector 20 shown in FIG. 1, when the rotation lever 30 is rotated, the first connector 10 and the second connector 20 are The coupling protrusion 22 is moved to the inlet of the coupling channel 34 while performing the coupling process in reverse.

At this time, when the striking surface 33 of the rotation lever 30 receives a force in a direction released from the interference with the locking slope 24b, the elastic arm 23b is deformed toward the support 15. When the striking surface 33 is kept in contact with the engaging slope 24b and is separated from the raised portion 24, the operator is required to engage the first connector 10 and the second connector 20. You can feel a sense of separation that is released.

Thereafter, when the coupling protrusion 22 of the second connector 20 comes out of the insertion channel 14 of the first connector 10, the first connector 10 and the second connector 20 are completely separated. .
