The housing 2 is formed in a substantially rectangular parallelepiped shape, and a plurality of terminal holes 2 'are provided therein in which a terminal (not shown) is installed.

One side surface of the housing 2 is formed so that the spacer hole 3 penetrates in a direction orthogonal to the terminal hole 2 ′. The spacer hole 3 is coupled to the spacer 5 for fixing the terminal installed in the terminal hole (2 ').

Both sides of the housing 2 are provided with a rotating shaft 7 formed to protrude a predetermined amount. The rotary shaft 7 is rotatably provided with a lever 9 for fixing the connector 1 and a mating connector (not shown) coupled to the connector 1.

However, the prior art having such a configuration has the following problems.

The lever 7 is made and mounted separately on the exterior of the housing 2 of the connector 1. Therefore, a problem arises in that the number of parts constituting the connector 1 increases and the number of labors for assembling work increases, leading to a high manufacturing cost of the connector.

The lever 7 is still attached to the connector 1 even after the connector 1 and the mating connector are coupled to each other, so that the space occupied by the connector 1 is required. That is, there is a problem that a lot of obstacles in miniaturization and space utilization of the product in which the connector 1 is used.

Therefore, an object of the present invention is to solve the problems of the prior art as described above is to provide a coupling / disconnecting device for a connector that is made separately from the connector and used only when the connector is coupled and separated.

According to a feature of the present invention for achieving the object as described above, the present invention is the first housing is formed with a hook projection and the first connector constituting the appearance and the receiving portion is inserted into which the first housing is formed, the operation projection on the inner surface In the connector housing / coupling device for coupling and disconnecting the second connector constituting the appearance of the second housing,

A hook channel is provided on which the hook projection of the first housing is hooked, and is mounted on both sides of the first housing, and a mounting channel is formed. A guide channel on which a manipulation protrusion of the user is formed is formed, and an interlocking bar having an interlocking gear is elongated along a longitudinal direction on one side of the outer surface and rotatably provided on the fixture and a driving gear meshing with the interlocking gear is formed on the outer surface. It comprises a control lever for linearly moving the linkage bar through the rotational movement for the fixture.

The distance between the hook channel and the guide channel in the state where the interlocking bar is inserted into the mounting channel of the fixture in a direction away from the first housing is such that the distance between the hook protrusion and the operating protrusion when the first and second housings are completely coupled. Corresponds to the distance.

The operating lever has a handle portion having a length corresponding to the distance between the fasteners of both ends, a leg portion extending from both ends of the handle portion, and formed in a disc shape at the tip of the leg portion and fitted into the rotating protrusion formed on the fastener.

The guide channel is formed by opening one side in a direction orthogonal to the longitudinal direction of the interlocking bar.

A stopper protrudes from the end of the interlocking bar protruding from the mounting channel and corresponding to the other side of the guide channel, and hangs at an inlet edge of the mounting channel.

In the connector coupling / separation device according to the present invention, the following effects can be obtained.

First, since the coupling / separation device of the present invention has a large number of terminals and can be used in common in a connector requiring a large coupling and separation force, it is not necessary to provide a configuration for coupling / separation for each connector, thereby reducing the number of parts of the connector and assembling. The labor cost can be reduced, which reduces the manufacturing cost.

In addition, since the connector coupling / separation device in the present invention is used only when the connector is coupled and separated, the space required for installation of the connector coupled to each other is not required because the connector does not have a configuration for coupling and disconnecting the connector. Minimization and space utilization of the product in which the connector is used can be minimized.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the connector for coupling / separating device according to the present invention will be described in detail.

As shown in the figures, the coupling / separating device 10 of the embodiment of the present invention has a width between the outer surface of the first housing 42 of the first connector 40 in which a pair of fasteners 11 will be described below. It is provided at intervals of. Each of the fasteners 11 is formed with a locking portion 12 along its longitudinal direction. As shown in FIG. 2, the locking portion 12 is provided on both sides of an outer surface of the fixture 11 to form a mounting channel 13 therebetween. At this time, the engaging portion 12 is a cross-section of the 'b' shape so that the linkage bar 17 to be described below can be stably maintained in the mounting channel (13).

A hook channel 14 is formed in the fixture 11. The hook channel 14 is formed to be recessed in the surfaces facing each other of the two fasteners 11, and the hook protrusion 46 of the first housing 42 to be described below is inserted therein. To this end, the hook channel 14 is formed to extend to the edge of the fastener 11, the front end is opened so that the hook projection 46 is easily inserted.

The fasteners 11 are integrally connected to each other by the connecting portion 15. The connecting portion 15 is cylindrical in this embodiment. However, the connecting portion 15 does not necessarily have to be cylindrical, and any shape may be used as long as the fasteners 11 can be connected to each other.

The fixture 11 is provided with a rotating plate (16). The rotating plate 16 is a portion to which the gear part 23 of the operation lever 20 to be described below is rotatably coupled, and the rotating protrusion 16 'is formed to protrude. As shown in FIG. 2, the rotating plate 16 is formed in a substantially semi-circular shape, but is not limited thereto, and may have a plate shape having various shapes.

The fastener 11 is coupled to the interlocking bar 17. The interlocking bar 17 has a plate shape having a predetermined area as shown in the drawing, and is installed in the mounting channel 13 of the fixture 11 so as to be able to enter and exit by a predetermined section. The linkage bar 17 serves to pull the operation protrusion 56 formed in the second housing 52 to be described below to pull in the direction of the first housing 42.

To this end, the guide channel 18 is formed in the interlocking bar 17. The guide channel 18 is a portion to which the operation protrusion 56 of the second housing 52 is hooked. The guide channel 18 extends to the edge of the interlocking bar 17 and the tip thereof is opened so that the operation protrusion 56 is easily inserted. It is formed.

In the present embodiment, the guide channel 18 is formed to penetrate a part of the outer surface of the interlocking bar 17, but is not necessarily the surface facing the inner surface of the second housing 52 of the second connector 50. It may be formed in the form of opening only.

At this time, in the state in which the interlocking bar 17 is inserted into the mounting channel 13 of the fixture 11 in the direction away from the first housing 42 as much as possible (the state of FIG. 2), the hook channel 14 The distance between the guide channel 18 and the guide channel 18 corresponds to the distance between the hook protrusion 46 and the manipulation protrusion 56 when the first and second housings 42 and 52 are completely coupled. This is because the second housing 52 is completely pulled in the direction of the first housing 42 while the operating protrusion 56 is inserted into the guide channel 18 while the operation lever 20 to be described below is rotated. To do so.

On the outer surface of the interlocking bar 17, an interlocking gear 17 'is formed. The interlocking gear 17 ′ engages with the drive gear 25 of the operating lever 20 so that the interlocking bar 17 moves linearly by the rotation of the operating lever 20. To this end, the interlocking gear 17 'is formed to extend in a straight line along the longitudinal direction of the interlocking bar 17.

At this time, the interlocking gear 17 'is exposed to the outside through the open portion of the locking portion 12 of the fixture 11, and is engaged with the interlocking gear 17' of the operating lever 20.

A stopper 19 is formed in the linkage bar 17. The stopper 19 is for regulating the extent to which the linkage bar 17 protrudes from the mounting channel 13 of the fixture 11 toward the first housing 42, and the other side of the guide channel 18. It is formed at the tip of the interlocking bar 17 corresponding to. That is, as the stopper 19 is hooked to the inlet edge of the mounting channel 13, the protruding degree of the linkage bar 17 is restricted.

The operation lever 20 is coupled to the fixture 11. The operation lever 20 performs a relative rotation with respect to the fixture 11, and serves to linearly move the linkage bar 17. To this end, the operation lever 20 is rotatably coupled to the fixture (11).

Looking in more detail, the handle lever 21 is formed on the operation lever (20). The handle portion 21 is a bar shape having a length corresponding to the distance between the fasteners 11 at both ends, and is a portion that the operator grips substantially to rotate the operation lever 20.

Leg portions 22 extend at both ends of the operation lever 20. The leg portion 22 serves to connect the handle portion 21 and the gear portion 23 to be described below in an approximately bar shape. Since the leg part 22 is a part rotated about the rotation protrusion 16 ′, the rotation torque of the operation lever 20 is determined according to its length. That is, the longer the length of the leg portion 22, the smaller the rotational torque, so the length of the leg portion 22 is preferably formed longer, but may be appropriately designed in consideration of the overall size of the operating lever 20.

A gear portion 23 is formed at the tip of the leg portion 22. The gear portion 23 is substantially disk-shaped, and is coupled to the outer surface of the rotating plate 16 of the fasteners 11 at both ends. More precisely, the gear part 23 is provided with a rotating hole 24, and the rotating protrusion 16 ′ is fitted into the rotating hole 24, so that the gear part 23 rotates with respect to the fixture 11. It becomes possible state.

The drive gear 25 is formed on the outer circumferential surface of the gear part 23. The drive gear 25 is a portion engaged with the interlocking gear 17 'of the interlocking bar 17 and serves to transmit the rotational force of the operation lever 20 to the interlocking bar 17.

Next, the configuration of the connector to be coupled or separated using the connector for coupling / disconnecting device of the present invention.

The first connector 40 is, for example, a female connector, and the first housing 42 having a substantially hexahedron shape forms an appearance and a skeleton. A plurality of terminal through holes 44 are formed through the first housing 42. Terminal (44) is inserted into each of the terminal through-hole is installed.

Hook protrusions 46 are formed on both outer surfaces of the first housing 42. The hook protrusion 46 is a part which is hooked to the hook channel 14 of the fixture 11. The hook protrusion 46 may be a cylindrical shape in the illustrated embodiment, but may not necessarily be, and may have a square pillar shape to prevent relative rotation with the fixture 11.

The second connector 50 is a male connector, and the second housing 52 forms an appearance and a skeleton. A terminal (not shown) is installed inside the second housing 52. An accommodating part 54 into which the first connector 40 is inserted is formed at an inner end of the second housing 52. The manipulation protrusion 56 protrudes from the inner surfaces of the accommodating portion 54 facing each other. The manipulation protrusion 56 is a portion guided along the guide channel 18 of the manipulation lever 20.

In this case, guide ribs 47 and guide channels 57 are formed in the first housing 42 and the second housing 52, respectively. The guide ribs 47 and the guide channels 57 are formed to correspond to each other, and serve to guide the coupling between the first and second connectors 40 and 50.

Hereinafter will be described in detail the operation of the connector coupling / separating device according to the present invention having the configuration as described above.

In order to couple the first and second connectors 40 and 50, the fastener 11 should be mounted to the first housing 42 of the first connector 40. To this end, the hook channel 14 of the fixture 11 is hooked to the hook protrusion 46. In this case, the two fasteners 11 are positioned to face the outer surface of the first housing 42.

In this state, the first connector 40 is positioned at the entrance of the accommodating part 54 of the second connector 50. When the first connector 40 is slightly pushed into the housing 54, the linkage bar 17 is also inserted into the space between the outer surface of the first housing 42 and the inner surface of the second housing 52. do. However, in this state, only the first housing 42 enters a part of the accommodating portion 54 of the second housing 52, and the terminals are not coupled to each other.

In this process, the operation protrusion 56 of the second housing 52 is located at the entrance of the guide channel 18 of the interlocking bar 17. At this time, the guide channel 18 and the hook channel 14 are formed to the edge of the interlocking bar 17 and the fastener 11, respectively, and the front end thereof is open, so that the operation protrusion 56 and the hook protrusion 46 ) Can be easily inserted. This is shown in FIG. 6.

In this state, the handle part 21 of the manipulation lever 20 is rotated about the rotation protrusion 16 '. That is, when the operation lever 20 is rotated in the clockwise direction with reference to FIG. 6, the gear part 23 is rotated about the rotation protrusion 16 ′.

Accordingly, the drive gear 25 formed in the gear unit 23 moves while being engaged with the interlock gear 17 'formed in the interlocking bar 17 to linearly move the interlocking bar 17. More precisely, the linkage bar 17 moves upward based on FIG. 6.

In this case, since the operation protrusion 56 is inserted into the guide channel 18 of the interlocking bar 17, the second connector 50 also naturally moves toward the first connector 40. In this process, the terminals inserted into the first and second connectors 40 and 50 are electrically connected to each other.

Now, the coupling / separating device 10 of the present invention should be removed from the first and second connectors 40 and 50 coupled to each other. To this end, when the manipulation protrusion 56 is released from the guide channel 18, and at the same time, the hook protrusion 46 is drawn out of the hook channel 14, the coupling / separating device 10 is connected to the first. And second connectors 40 and 50. In this state, the coupling / separation device 10 is completely separated from the first and second housings 42 and 52.

On the other hand, it is described that the first and second connectors 40 and 50 are separated from each other using the coupling / separation device 10 of the present invention in a state in which the first and second connectors 40 and 50 are coupled to each other. do. Of course, the separation process is the reverse of the combining process described above.

That is, the operator first rotates the handle 21 of the operating lever 20 along the rotation protrusion 16 ′ in the counterclockwise direction when viewed with reference to FIG. 7. In this case, the drive gear 25 of the gear unit 23 rotates in engagement with the linkage gear 17 'of the linkage bar 17 to linearly move the linkage bar 17. In this process, the second connector 50 is moved away from the first connector 40, and the separating operation is performed. Finally, as described above, the coupling / separating device 10 is separated from the first and second housings 42 and 52 to finish.
