Description

Lever type connector {LEVER TYPE CONNECTOR}

The present invention relates to a lever-type connector, and more particularly, when assembling a main housing and a mating housing by rotation of a lever, a plurality of guide holes are made through the lever and guide protrusions are formed in the main housing to correspond to each of the guide holes. By doing so, it increases the binding force of the lever in the state that the main housing and the mating housing are bound, and prevents eccentric coupling between the main housing and the mating housing by configuring a plurality of support binding parts of the main housing to the mating housing, and the trajectory of each guide hole. It relates to a lever-type connector to further improve the restraining force of the lever by preventing the arbitrary separation of the corresponding guide protrusion by differently.

In recent years, as carbon energy is gradually depleted and interest in the environment is increasing, public attention has been focused on hybrid and electric vehicles worldwide, including the United States, Europe, Japan, and Korea.

In the case of a hybrid vehicle or an electric vehicle, a high voltage/high current is used compared to a general vehicle, and thus an electric device for stably supplying and distributing power supplied from the outside of the vehicle to parts inside the vehicle is required.

In addition, many parts are manufactured in the form of modules for electronic control of vehicles, and the use of wires or communication lines to which a connector is connected to transmit a current or electric signal has rapidly increased.

Such a connector is used to electrically connect parts of a vehicle, and is subjected to various safety inspections so as not to cause electrical defects when mounted on parts of a vehicle.

In addition, a conventional connector includes a female housing and a male housing that are detachable from each other, and further includes a connector position assurance (CPA) member to prevent the female housing and the male housing from being separated from each other. When the female housing and the male housing are combined, the CPA is coupled to the unlocking button to prevent the unlocking button of the female housing from being pressed, and is provided to be separated from the unlocking button when the female housing and male housing are separated.

However, in order to separate the male housing from the female housing, such a conventional connector must first slide the CPA and then press the unlocking release button to separate the female housing from the male housing, so the operation of the CPA and the unlocking button is fixed. In addition to this inconvenience, since the CPA is inserted into the lock release button, the gripping space of the CPA is narrow, making it difficult to operate.

In order to solve this problem, recently, a lever-type vehicle connector has been proposed in order to reduce a working space for coupling and detaching the female housing and the male housing, and to increase the workability of the coupling and detachment.

1 to 7, the lever-type connector 10 according to an embodiment of the present invention includes a lever 40, an elastic coupling part 100, a main coupling holding part 200, and a sub-binding holding part ( 300).

After assembling the main housing 20 and the mating housing 30, the lever 40 serves to bind the assembled state of the main housing 20 and the mating housing 30.

In particular, the main housing 20 is formed to protrude fastening protrusions 26 on both outer side surfaces or both inner side surfaces. In addition, a part of the mating housing 30 is assembled by being axially inserted into the main housing 20. Of course, the main housing 20 and the counter housing 30 can be deformed into various shapes.

In addition, the lever 40 passes through the fastening hole 46 to insert the fastening protrusion 26 of the main housing 20. Thus, the lever 40 is rotatable based on the fastening protrusion 26. At this time, the lever 40 includes a grip portion 42 that can be held by hand for rotation, and a rotation portion 44 extending from both sides of the grip portion 42 and passing through the fastening holes 46, respectively. Of course, the grip portion 42 and the rotation portion 44 can be deformed into various shapes.

In particular, for the assembly direction of the lever 40, the shape of the fastening protrusions 26 protruding from both sides of the main housing 20 may be different. In this case, the corresponding fastening holes 46 are also different.

When a part of the mating housing 30 is inserted into the main housing 20, the fastening protrusion 26 is provided on the main housing 20 so as to be exposed to the outside of the mating housing 30, or inside the mating housing 30. It may be provided in the main housing 20 so as to be located.

On the other hand, the elastic coupling part 100, after a part of the mating housing 30 is inserted into the main housing 20, while rotating the lever 40, the mating housing 30 is moved to the main housing 20 by elastic deformation force. It plays a role of elastically pressing the side.

In addition, the main binding holding unit 200 is interlocked with the operation of the elastic binding unit 100, serves to keep the mating housing 30 bound to the main housing 20, and the lever 40 It serves to support the mating housing 30 in a direction opposite to the direction in which the elastic restoring force is generated.

The sub-binding holding unit 300 is interlocked with the operation of the main binding holding unit 200 and serves to increase the binding force of the mating housing 30 to the main housing 20, and generates an elastic restoring force of the lever 40. It serves to support the mating housing 30 in a direction opposite to the direction.

In detail, the elastic coupling part 100 includes a support rib 110 and an elastic rib 120.

The support rib 110 is provided outside or inside the mating housing 30. For convenience, the support ribs 110 are provided on one inner side or both inner sides of the mating housing 30. At this time, the support rib 110 may be made of a hard material, or may be made of a soft material capable of elastically deformable by an external force greater than or equal to a set force.

In addition, the elastic rib 120 is extended so as to be elastically deformable from the lever 40, in particular, the corresponding rotating part 44, and the lever 40 is rotated for assembling the mating housing 30 and the main housing 20. At the time, it is moved along the support rib 110 and is supported by the support rib 110. At this time, the elastic rib 120 presses the support rib 110 in one direction, so that the contact surface of the assembled mating housing 30 and the main housing 20 is in close contact, and the lever 40 is arbitrarily rotated in the opposite direction. By preventing this, the assembly state of the main housing 20 and the mating housing 30 can be maintained.

Accordingly, when the support rib 110 is elastically deformable, the elastic deformability of the elastic rib 120 is greater than the elastic deformability of the support rib 110.

In addition, the support rib 110 has a first inclined end 112 formed at the end in the axial direction, and the elastic rib 120 has a second inclined end 122 at the end so as to be symmetrical with the first inclined end 112 To form.

So, when the lever 40 is initially rotated for assembling the mating housing 30 and the main housing 20, the first inclined end 112 and the second inclined end 122 are interviewed. Thereafter, when the lever 40 is further rotated, the elastic rib 120 is moved in the lateral direction of the support rib 110 in an elastically deformed state. In particular, the elastic rib 120 forms a bent portion 124 at a portion adjacent to the rotation portion 44. Thus, in a state in which the lever 40 is completely rotated in contact with the mating housing 30, the force that the bent portion 124 pushes the support rib 110 in one direction is maximized.

Thereby, the lever 40 is prevented from rotating in the opposite direction.

At this time, the elasticity of the elastic rib 120 decreases when a long time elapses. Thus, the lever 40 can be arbitrarily rotated in the opposite direction.

To prevent this, a main binding holding unit 200 and a sub binding holding unit 300 are provided.

The main binding holding unit 200 includes a main guide protrusion 210 and a main receiving binding tool 220.

The main guide protrusion 210 is formed to protrude from the circumferential surface or the inner surface of the mating housing 30. For convenience, the main guide protrusion 210 is shown to protrude from the inner surface of the counter housing 30. The main guide protrusion 210 can be deformed into various shapes.

The main receiving and fastening tool 220 is formed on the lever 40 that rotates with respect to the fastening protrusion 26 and serves to accommodate the corresponding main guide protrusion 210. So, the main receiving fastening tool 220 is made of a hole or groove shape.

At this time, when the lever 40 is completely rotated so that the elastic rib 120 is pushed in the lateral direction from one side of the support rib 110, the main guide protrusion 210 is the main housing ( 20) and the mating housing (30). Thus, the mating housing 30 and the main housing 20 are prevented from being assembled eccentrically.

In particular, the main receiving and fastening unit 220, the first main receiving area 230 and the second main receiving area in which the curvature of the trajectory is different based on a point in time when the elastic deformation force of the elastic bonding unit 100 increases by more than a set value. It is divided into 240.

In detail, when the first inclined end 112 and the second inclined end 122 are interviewed, the main guide protrusion 210 is positioned at the entrance side of the first main receiving area 230 of the main receiving fastening tool 220. do.

At this time, the main guide protrusion 210 moves the main receiving fastening unit 220 while the position is fixed, but for convenience, the main guide protrusion 210 will be described as moving along the trajectory of the main receiving fastening unit 220.

When the end-side edge of the elastic rib 120 gradually moves in the lateral direction of the support rib 110, the main guide protrusion 210 gradually moves into the first main receiving area 230.

When the bent portion 124 of the elastic rib 120 contacts the first inclined end 112 of the support rib 110, the main guide protrusion 210 is the first main receiving area 230 and the second main receiving area It is located at the connection part of (240).

Thereafter, when the bent portion 124 is positioned in the side direction of the support rib 110, the main guide protrusion 210 is a second main receiving area 240 having a trajectory different from that of the first main receiving area 230. ).

As the trajectories of the first main receiving area 230 and the second main receiving area 240 are different, the main guide protrusion 210 located in the second main receiving area 240 is arbitrarily selected as the first main receiving area. It is prevented from being moved to 230.

In addition, the sub-binding holding unit 300 includes a sub-guide protrusion 310 and a sub-receiving binding tool 320.

The sub-guide protrusion 310 is formed to protrude from the circumferential surface or the inner surface of the mating housing 30. For convenience, the sub-guide protrusion 310 is shown to protrude from the inner surface of the mating housing 30.

In addition, the sub-receiving fastening tool 320 is formed on the lever 40 that rotates with respect to the fastening protrusion 26 and serves to accommodate the corresponding sub-guide protrusion 310. So, the sub-receiving binding tool 320 is made of a hole or groove shape.

At this time, when the lever 40 is completely rotated so that the elastic rib 120 is pushed in the lateral direction from one side of the support rib 110, the sub-guide protrusion 310 is a relative housing ( 30) and the main housing (20). Thus, the mating housing 30 and the main housing 20 are prevented from being assembled eccentrically.

In particular, the sub-receiving fastening sphere 320 has a first sub-receiving region 330 and a second sub-receiving region that vary the curvature of the trajectory based on a point in time when the elastic deformation force of the elastic binding unit 100 increases by more than a set value. It is divided into 340.

In detail, when the first inclined end 112 and the second inclined end 122 are interviewed, the sub-guide protrusion 310 is positioned at the entrance side of the first sub-receiving area 330 of the sub-receiving fastener 320. do.

Likewise, the sub-guide protrusion 310 moves the sub-receiving fastener 320 while the position is fixed, but for convenience, it will be described that the sub-guide protrusion 310 moves along the trajectory of the sub-receiving fastener 320.

When the end-side edge of the elastic rib 120 gradually moves in the lateral direction of the support rib 110, the sub-guide protrusion 310 gradually moves into the first main receiving area 230.

When the bent part 124 contacts the first inclined end 112 of the support rib 110, the sub-guide protrusion 310 is a connection part between the first sub-receiving region 330 and the second sub-receiving region 340 Will be located in.

Thereafter, when the bent portion 124 is positioned in the lateral direction of the support rib 110, the sub-guide protrusion 310 is a second sub-receiving area 340 having a trajectory different from that of the first sub-receiving area 330. ).

As the trajectories of the first sub-receiving region 330 and the second sub-receiving region 340 are different, the sub-guide protrusion 310 located in the second sub-receiving region 340 is arbitrarily selected as the first sub-receiving region. It is prevented from being moved to 330.

That is, in the state in which the main housing 20 and the mating housing 30 are assembled, when the lever 40 is fully rotated in the locking direction, the elastic rib 120 that presses the support rib 110 in the lateral direction, the main accommodation The main guide protrusion 210 moved to the second main receiving area 240 of the binding tool 220, and the sub guide protruding part 310 moved to the second sub receiving area 340 of the sub receiving fastening unit 320 By this, the lever 40 is prevented from being arbitrarily moved in the unlocking direction.

Thus, the main housing 20 and the mating housing 30 are firmly maintained in an assembled state and maintained in a correctly assembled state while eccentricity is prevented.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only illustrative, and those of ordinary skill in the field to which the technology pertains, various modifications and other equivalent embodiments are possible.
