According to the present invention, a lever (20) is rotationally installed in a first connector (10), and a second connector (30) coupled to the first connector (10) performs electrical connection. Provided is a stop protrusion (42) which slows the rotation of the lever (20) in the second connector (30) during rotation in a direction of rotating directions of the lever (20), which separates the first connector (10) and the second connector (30). The stop protrusion (42) is formed at one end of a connection part (44) which is elastically deformable. An interworking guide face (43) and a hanging face (43) are formed on opposite sides in the stop protrusion (42). The interworking guide face (43), having a certain slope with respect to a moving direction of a hanging part (29), guides the hanging part (29) with the stop protrusion (42) moving backward when the hanging part (29) moves. The hanging face (43) perpendicular to the moving direction of the hanging part (29) is hung in the stop protrusion (42) to prevent rotation of the lever (20) when the hanging part (29) moves. Terminals (15, 16) of the first connector (10) separate from a terminal (36) of the second connector (30) after a delay after a first interlock terminal (19) and a second interlock terminal (39) separate, which prevents spark generation.

Description

[0001]

The present invention relates to a connector assembly, and more particularly, to a connector assembly having an interlock terminal for preventing a spark from occurring in a terminal that is energized when a connector is detached.

A connector for electrical connection is used at a voltage as low as 12 volts. Recently, an electric vehicle has begun to be mass-produced, and it is widely used at a high voltage of several hundred volts. Connectors used at high voltages are relatively large in size compared to connectors used at low voltages. Thus, there is a problem in that the size of each connector or the connector assembly to which they are coupled increases.

Further, there is a problem that sparks are generated when terminals that are energized by being coupled with each other while being used at a high voltage are separated. Such a spark causes deformation of the housing, which forms the outer appearance and skeleton of the connector, and causes a fire even in severe cases.

To overcome this, an interlock terminal is used which provides a signal to cause the energization through the terminal to be terminated before the connection between terminals for energization is disconnected.

However, if the separation of the connectors from the connector assembly is performed at a high speed, the terminal for energizing is disconnected in a very short time after the separation between the interlock terminals, so that the interlock terminal can not function effectively.

 In order to solve such a problem, the rotation of the lever is advanced in a multi-step manner as described in the following prior art documents, so that a constant delay time is ensured after the interlock terminal is separated, . However, in the prior art document, there is a problem that the number of parts is increased and the structure is increased, for example, by providing a lever latch for restricting the operation of the lever to the connector on which the lever is installed.

As shown in the drawings, the connector assembly of the embodiment of the present invention includes a first connector 10 and a second connector 30. The first connector 10 and the second connector 30 are coupled to each other to perform an electrical connection.

The first housing 12 forms an outer appearance and a skeleton of the first connector 10. The first housing 12 is made of an insulating synthetic resin. A first terminal installation space (14) is formed through the inside of the first housing (12). A first terminal (15) is installed in the first terminal installation space (14). The first terminal installation space (14) corresponding to the tip of the first terminal (15) has a connection terminal (16). The connection terminal 16 is a both-end receptacle terminal, and the first terminal 15 is inserted at one end and the second terminal 36 of the second connector 30 is inserted at the other end, And is electrically connected. However, the first terminal 15 and the second terminal 36 may be directly coupled and electrically connected.

On both outer surfaces of the first housing 12, a projection slot 17 is formed long. The protrusion slot 17 is formed to be open to the front end of the first housing 12. An engaging projection 38 of the second connector 30, which will be described below, is inserted and guided in the projection slot 17. [

A rotation center shaft 18 protrudes from both sides of the outer surface of the first housing 12 adjacent to the end of the protrusion slot 17. The rotation center shaft 18 is provided with a lever 20 to be described below. The rotation center shaft 18 serves as a rotation center of the lever 20. [

Meanwhile, a first interlock terminal 19 is installed in the first housing 12. The first interlock terminal 19 is engaged with and disengaged from the second interlock terminal 39 of the second connector 30 to be described below and the combination of the first connector 10 and the second connector 30 Thereby providing a signal for separation.

The lever 20 acts as a lever and transmits a force for engagement and disengagement of the first connector 10 and the second connector 30. [ The lever 20 includes a lever mounting plate 24 provided at both ends of the lever handle 22. The lever mounting plate 24 is seated on both outer surfaces of the first housing 12 with a predetermined shape. A rotation hole 26 is formed in the lever mounting plate 24 so that the rotation center shaft 18 of the first housing 12 is positioned.

The lever mounting plate 24 also has an interlocking slot 28 formed therein. The interlocking slot 28 is a portion where the interlocking projection 38 of the second connector to be described below is guided and moved. The distance of the interlocking slot 28 from the rotating through hole 26 gradually becomes shorter from the entrance of the interlocking slot 28 to the inner side.

The lever mounting plate 24 of the lever 20 has hook portions 29, respectively. The hooking portions 29 protrude from one side of the lever mounting plate 24. The hook portion 29 is hooked on the stop protrusion 42 which will be described later in the process of separating the first connector 10 and the second connector 30 from each other. When the lever 20 is engaged with the first connector 10 and the second connector 30, the lever 20 can be rotated without being guided by the interlocking guide surface 43 of the stopper 42 do.

The second housing (32) forms an outer appearance and a skeleton of the second connector (30). The second housing 32 is also made of an insulating synthetic resin. The second terminal seating space 34 is formed by passing through the second housing 32 forward and backward. A second terminal (36) is installed in the second terminal seating space (34). The second terminal 36 is electrically connected to and separated from the terminals 15, 16 in the first connector 10.

Interlocking protrusions 38 protrude from outer surfaces of both sides of the second housing 32. The interlocking protrusion 38 is guided along the interlocking slot 28 of the lever 20 so that the second connector 30 and the first connector 10 are moved toward and away from each other.

A second interlock terminal 39, which can be engaged with the first interlock terminal 19, is installed in the second housing 32. So that the engagement of the second interlock terminal 39 and the first interlock terminal 19 is released before the second terminal 36 is separated from the terminals 15 and 16 of the first connector 10. [ .

On the outer surface of the second housing 32, a mounting plate 40 is provided. The mounting plate 40 has a plurality of fastening holes (not shown) adjacent to the corner for mounting the second connector 30 to the fixing portion.

The mounting plate (40) has a stop projection (42). The interlocking guide surface 43 and the back surface 43 'of the stop protrusion 42 are opposite to each other. The interlocking guide surface 43 has a predetermined inclination so that the hooking portion 29 of the lever 20 is guided to elastically deform the connection portion 44 formed with the stop protrusion 42. The interlocking guide surface 43 is formed to have a predetermined inclination with respect to the moving direction of the hook 29 when the lever 20 is rotated.

 The hooking surface 43 'is formed on the opposite side of the interlocking guide surface 43 and is formed to be perpendicular to the moving direction of the hooking portion 29 when the lever 20 is rotated. The hooking surface 43 'is provided on the rear surface of the hook 20 so as to temporarily block the rotation of the lever 20 when the lever 20 is rotated for separating the first connector 10 and the second connector 30 from each other. So that the portion 29 is hooked.

The stop projection 42 is connected to the mounting plate 40 via a connecting portion 44. Of course, the stop protrusion 42 may be directly connected to the second housing 32 through the connection portion 44. [ The connecting portion 44 is formed in a cantilever shape and has the stop projection 42 at its tip end. And a release lever 46 is provided to connect the connection portions 44 on both sides. The release lever 46 connects the stop projections 42 on both sides so that the stop projections 42 on both sides are simultaneously operated. In this embodiment, the release lever 46 has a U-shape. At one side of the release lever 46, there is a release handle 48, which allows the release lever 46 to be easily operated by an operator.

Hereinafter, the connector assembly according to the present invention will be described in detail.

In order to allow the first connector 10 and the second connector 30 to be coupled with each other, the lever 20 mounted on the first connector 10 is in a state shown in FIG. 6, 17 and the inlet of the interlocking slot 28 coincide with each other. In this state, the first connector 10 and the second connector 30 are opposed to each other, and the interlocking protrusion 38 of the second connector 30 is inserted into the protrusion slot 17 and the interlocking slot 28 Enter.

The lever 20 is rotated in the direction of arrow A in FIG. 6 in a state in which the interlocking projection 38 enters the protrusion slot 17 and the interlocking slot 28. As the interlocking protrusion 38 moves along the interlocking slot 28, the first connector 10 is engaged with the second connector 30 by the lever 20, . In this process, the latching portion 29 of the lever 20 moves along the interlocking guide surface 43 of the stop protrusion 42, as shown in FIG. When the hooking portion 29 is guided along the interlocking guide surface 43, the stopping projection 42 is pushed by the hooking portion 29. In other words, the connection portion 44 and the release lever 46 are elastically deformed, so that the stop projection 42 does not interfere with the rotation of the lever 20.

The lever 20 is continuously rotated so that when the interlocking projection 38 comes to the end of the interlocking slot 28 as shown in FIG. 8, the first connector 10 and the second connector 10 The connection of the connector 30 is completed.

7, the second terminal 36 and the first connection terminal 16 start to be engaged, and the hook portion 29 of the lever 20 is engaged with the stop protrusion 42 The first interlock terminal 19 and the second interlock terminal 39 are coupled to each other. When the first and second interlock terminals 19 and 39 are coupled to each other, power is supplied from the first terminal 15 through the first connection terminal 16 and the second connection terminal 36, .

When the first connector 10 and the second connector 30 are electrically coupled to each other while the first connector 10 and the second connector 30 are electrically connected to each other, The generation of sparks between the second terminal 36 and the first connection terminal 16 is prevented.

The coupling protrusion 38 of the second connector 30 is inserted into the interlocking slot 28 of the lever 20 when the lever 20 is rotated in a direction opposite to that when the lever 20 is engaged with the connector 10, As a result, the coupling between the first connector 10 and the second connector 30 begins to separate.

The first interlock terminal 19 and the second interlock terminal 39 are connected to each other before the lever 20 is rotated so that the latching portion 29 is hooked on the stop projection 42, Are separated. The state in which the first interlock terminal 19 and the second interlock terminal 39 are separated can also be seen in FIG. However, the coupling between the second terminal 36 and the first connection terminal 16 is not yet separated as can be seen in FIG.

The hook portion 29 of the lever 20 is hooked to one side of the second connector 30 immediately after the first interlock terminal 19 and the second interlock terminal 39 are separated. That is, the latching portion 29 of the lever 20 is hooked on the stop protrusion 42 of the second connector 30, so that the lever 20 can not rotate any more. The stop protrusion 42 must be retracted from the hook 29 to allow the lever 20 to rotate further. This can be accomplished by the operator by operating the release lever 46. That is, the operator can press the release knob 48 so that the stop projection 42 is separated from the hook portion 29 of the lever 20 and retracted. A predetermined period of time must be delayed in order for an operator to operate the release knob 48 to cause the release lever 46 to be elastically deformed.

At this time, since the separation between the first interlock terminal 19 and the second interlock terminal 39 has already been performed, the second terminal 36 and the first connection terminal 16, The energization through the first terminal 15 is stopped. In this state, energization through the terminals 36, 16, 15 is interrupted, but these terminals 36, 16, 15 are still coupled as shown in Fig.

When the stop protrusion 42 is retracted and the lever 20 is continuously rotated, the interlocking protrusion 38 moves toward the inlet of the interlocking slot 28, so that the first and second connectors 10, (30) are gradually separated from each other. In this process, the coupling between the second terminal 36 and the first connection terminal 16 is separated. Since the energization is already stopped, no spark is generated.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.

For reference, in the illustrated embodiment, the first terminal 15 and the first connection terminal 16 are installed in the first connector 10 at the same time, , And the second terminal (36) of the second connector (30).

The stop protrusion 42 is formed on one side of the second housing 32 of the second connector 30 and is in the mounting plate 40 in the second housing 32 in this embodiment.

Also, the connection portions 44 are connected to each other by the release lever 46 in the illustrated embodiment, but this is not necessarily so. That is, the connecting portion 44 may not be connected by the release lever 46 but may be configured to be elastically deformed by the operation of the operator.

In the illustrated embodiment, when the connector (10, 30) is engaged in the rotation direction of the lever (20), the hook portion (29) passes the stop projection (42) while elastically deforming the connector The stopper 42 engages with the stopper 42 so that the worker artificially moves the stopper 42 back to advance the rotation of the lever 20. However, the hook 29 may be always hooked on the stop protrusion 42 so that the operator may artificially retract the stop protrusion 42.

Of course, when the connectors 10, 30 are detached, the latching portions 29 are always hooked on the stop protrusions 42 so that the levers 20 can be manually operated so that the lever 20 is rotated further. .
