The present invention relates to a connector, and more particularly, to a method of coupling / detaching a connector for coupling and detaching a connector, which uses a large number of terminals.

A connector is generally one that makes electrical connections between wires. Recently, as the number of terminals used in one connector increases, a lot of force for coupling and disengaging between the connectors is increased. Levers are also used to facilitate the mating and disengaging of connectors with a large number of terminals.

Figure 1 is a perspective view of the configuration of a lever type connector according to the prior art. In general, the appearance and skeleton of the connector 1 are formed by the housing 2. 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.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and provides a method of coupling / detaching a connector by using a connector / separation device of a connector that is made separately from the connector and is used only when the connector is coupled and separated. It is.

According to a feature of the present invention for achieving the object as described above, the present invention is a first housing formed with a hook projection and the first connector constituting the appearance and the receiving portion is inserted is provided with the operation projection is provided A pair of operating levers provided with a pair of fasteners provided with a hook channel hooked to the hook protrusion and a guide channel on which the operating protrusions are guided so that the second housing combines and detaches a second connector constituting the exterior; In the method of engaging the connector using a coupling / disconnecting device of the connector is provided through the center of rotation through the hook, the step of hooking the hook channel of the fastener to the hook projection of the first connector, and the second connector Walking the operating protrusion at a position farthest from the rotation center axis among the guide channels of the operation lever, and rotating the operation lever about the rotation center axis.

It comprises a step of separating.

In separating the operation projection of the operation lever and the second connector, the operation lever is moved in the longitudinal direction of the rotational axis to rotate, and in the case of detaching the hook protrusion from the fixture, the hook protrusion is connected to the hook channel of the fixture. To be reversed

According to another feature of the invention, 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 inserted and the second housing provided with the operating projection constitutes the appearance The central axis of rotation is provided through a pair of fasteners provided with a hook channel hooked to the hook protrusion and a pair of operating levers provided with guide channels guided by the manipulation protrusion to engage and separate the second connector. A method of detaching a connector using a coupling / disconnecting device of a connector, the method comprising: hooking a hook channel of the fixture to a hook protrusion of the first connector, and guiding the manipulation protrusion of the second connector to the manipulation lever. Walking to a position closest to the rotation center axis of the channel, and rotating the operation lever about the rotation center axis to cause the operation projection to be raised. Information is moved to the farthest location from the center of rotation of the channels and separating the first connector and the second connector from the first connector and the second connector is configured to include a step of separating the fixture and the operating lever.

In inserting the operation projection of the second connector into the guide channel of the operation lever, the operation lever is moved in the longitudinal direction of the rotation center axis.

The hanger has a prismatic shape.

In the method of coupling / detaching the connector according to the present invention, the following effects can be obtained.

First, since the coupling / separation apparatus using the coupling / disconnection method 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 have a configuration for coupling / disconnection for each connector. Since the number can be reduced and the number of assembly operations can be reduced, manufacturing cost is reduced.

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 because it can be minimized.

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

As shown in the figures, a coupling / separation device to which the present invention is applied is a pair of fixtures 10 having a width equal to the width between the outer surfaces of the first housing 42 of the first connector 40 to be described below. Equipped with. The fixture 10 is integrally connected to each other by a connecting portion 12. The connecting portion 12 is cylindrical in this embodiment. However, the connecting portion 12 does not necessarily have to be cylindrical, and any shape may be used as long as the fixture 10 can be connected to each other. For reference, the connection of the fixture 10 does not necessarily need to be made by the connecting portion 12, but may be connected by the rotation center axis 16 to be described below. That is, the fixture 10 may be integrally formed on the rotation center shaft 16 to have a predetermined interval.

The fasteners 10 each have a plate shape having a predetermined area, and a hook channel 14 is formed starting from the center portion to one edge thereof. The hook channel 14 is formed to be open to both sides of the fastener 10 in the present embodiment, but need not necessarily, only the opening facing the outer surface of the first housing 42 to be described below. It can be formed.

The rotation center shaft 16 is installed through the fixture 10, and stoppers 18 are formed at both ends. The stopper 18 has a larger outer diameter than the other parts of the rotation center axis 16. At least one of the stoppers 18 should be formed separately from the center of rotation axis 16 to be coupled to the center of rotation shaft 16 by indentation. This is to enable the installation of the fixture 10 and the operation lever 20 to be described below. Of course, when the rotation center shaft 16 is a mold, both ends of the rotation center shaft 16 on which the stopper 18 is formed are partially cut in the longitudinal direction of the rotation center shaft 16 so that the stopper is elastically deformed. By varying the distance between the outer surfaces of both sides of (18), the assembly of the fixture 10 and the operation lever 20 may be made possible.

The operation lever 20 is rotatably installed on the rotation center shaft 16. The operation lever 20 is rotatably installed at each of both ends of the rotation center shaft 16. The operation lever 20 is rotated about the rotation center axis 16 in a state where the fastener 10 is engaged with the first connector 40 so that the first connector 40 and the second connector 50 are rotated. To make the association. The operation lever 20 is also possible to move in the longitudinal direction of the rotation center axis (16).

The operation lever 20 is provided with a channel portion 22 in the form of a plate. A central hole 21 is drilled at one end in the channel portion 22. The center hole 21 is a portion through which the rotation center axis 16 passes. The channel section 22 is also provided with a guide channel 24. The guide channel 24 is formed starting from one edge of the channel portion 22 to a position substantially adjacent to the other edge. At this time, the distance between the guide channel 24 and the center hole 21 is gradually changed from one end of the guide channel 24 to the other end. That is, the distance from the inlet of the guide channel 24 to the separation channel 24 to be described below is gradually closer to the center hole 21.

In the present embodiment, the guide channel 24 is formed to penetrate the channel portion 22 of the operating lever 20, but is not necessarily the second housing 52 of the second connector 50 to be described below. It may be formed in the form of opening only to the surface facing the inner surface of the).

The separation channel 24 is formed to be connected to a portion of the guide channel 24 that is relatively close to the center hole 21. One end of the separation channel 24 is connected to the guide channel 24, and the other end thereof is formed to the edge of the channel part 22. In the present embodiment, the separation channel 24 is not formed to penetrate both sides of the channel portion 22. This is because when the guide channel 24 and the separation channel 24 both open to both sides of the channel part 22, the channel part 22 is divided into two parts. Therefore, at least one guide channel 24 and the separation channel 24 should not be open to both sides of the channel portion 22. In the separation channel 24, the distance to the center hole 21 should be constant throughout the entire portion.

The handle part 28 is extended to the operation lever 20 so as to extend from one side of the channel part 22. The handle portion 28 is preferably formed to extend in the opposite direction to the channel portion 22 with the center hole 21 is formed in the center.

Restoration members 30 are provided on the rotation center shaft 16 such that the operating levers 20 on both sides are in close contact with the stopper 18 of the rotation center shaft 16, respectively. The restoration member 30 is a cylindrical coil spring is used. The restoring member 30 is located between the outer surface of the central axis of rotation 16 and the inner surface of the connecting portion 12 inside the connecting portion 12.

The connecting shaft 32 is installed to penetrate the handle portion 28 of the operation lever 20 on both sides. Stoppers 34 are formed at both ends of the connecting shaft 32 to prevent the handle portion 28 of the operating lever 20 from being detached from the connecting shaft 32. The length of the connecting shaft 32 is equal to or slightly shorter than the rotation center shaft 16. When the length of the connecting shaft 32 is shorter than the length of the rotation center shaft 16, it is preferable that the operating lever 20 is capable of some degree of elastic deformation. This is to allow the operation lever 20 to be movable in the longitudinal direction of the rotation center axis 16. In this case, the handle portion 28 does not have to rotate or move relative to the connecting shaft 32. However, when the rotation center shaft 16 and the connecting shaft 32 have the same length, the handle portion 28 of the operating lever 20 should be movable in the longitudinal direction with respect to the connecting shaft 32. Of course, in this case, the handle portion 28 does not need to be rotated relative to the connecting shaft 32.

On the other hand, the configuration of the connector to be coupled or separated by using the coupling / disconnection method for the connector 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 10. The hook protrusion 46 may have a cylindrical shape in the illustrated embodiment, but may not necessarily be, and may have a prismatic shape, most preferably a square shape, to prevent relative rotation with the fixture 10.

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 24 of the manipulation lever 20.

Hereinafter, the operation of the coupling / disconnection method of the connector according to the present invention having the configuration as described above in detail.

In the present invention, the process of joining the connectors 40 and 50 using the coupling / separation device is shown in FIGS.

In order to couple the first and second connectors 40 and 50, the fastener 10 must be mounted to the first housing 42 of the first connector 40. To this end, the hook channel 14 of the fixture 10 is hooked to the hook protrusion 46. In this case, the fasteners 10 on both sides 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 operation lever 20 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.

At this time, the operation protrusion 56 of the second housing 52 is positioned at the entrance of the guide channel 24 of the operation lever 20. In this state, the handle part 28 of the operating lever 20 is rotated about the rotation center axis 16. That is, when the manipulation lever 20 is rotated in the arrow direction shown in FIG. 5, the manipulation protrusion 56 moves along the guide channel 24.

The guide channel 24 is closer to the central axis of rotation 16 toward its separation channel 24 at its inlet. Here, since the rotation center shaft 16 is mounted to the first housing 42 of the first connector 40 together with the fixture 10,

The close proximity of the center of rotation shaft 16 and the manipulation protrusion 56 means that the first connector 40 and the second connector 50 are close to each other. That is, as shown in FIG. 6, while the operation lever 20 rotates, the first connector 40 is accommodated in the accommodating part 54 of the second connector 50, and thus the coupling between the terminals is performed. .

Now, it is necessary to remove the coupling / disengagement device from the connectors 40 and 50 coupled to each other. To this end, the operation levers 20 on both sides are pressed in a direction closer to each other along the rotation center axis 16. That is, the control lever 20 is moved along the rotational center axis 16 while overcoming the elastic force of the restoring member 30. In this state, the operation lever 20 is rotated so that the operation protrusion 56 enters the separation channel 26 from the guide channel 24. This is possible because the operating lever 20 moves along the central axis of rotation 16 and slightly falls from the inner surface of the second housing 52.

When the manipulation protrusion 56 exits the separation channel 26 by the continuous rotation of the manipulation lever 20, the coupling between the manipulation lever 20 and the second housing 52 is released. In this state, when the hook protrusion 46 of the first housing 42 moves from the hook channel 14 of the fixture 10 to the opposite direction when the insert is inserted, the hook channel 14 is reversed. The disconnect device is disconnected from the connectors 40 and 50.

On the other hand, it will be described that the connector (40, 50) to separate the connector (40, 50) using a coupling / disconnection device in a state that is coupled to each other. Of course, the separation process is the reverse of the combining process described above.

First, the fastener 10 and the channel portion 22 of the control lever 20 are inserted between the first and second housings 42 and 52. At this time, the hook protrusion 46 is positioned at the inlet of the hook channel 14 of the fixture 10, and the manipulation protrusion 56 is positioned at the outlet of the separation channel 26 of the manipulation lever 20.

The hook projection 46 is hooked to the hook channel 14 of the fixture 10, and the rotation center shaft (2) is then overcoming the elastic force of the restoring member 30. The manipulation protrusion 56 is positioned in the separation channel 26 while moving along 16). These processes may be performed at the same time, the hook operation of the fastener 10 and the hook projection 46 is made first, and then, the operation lever 20 is rotated to the operation channel 56 in the separation channel 26. It can also be located at. For reference, in the process in which the fastener 10 and the hooking protrusion 46 are hooked, the operation lever 20 is rotated in a direction of falling out between the first and second housings 42 and 52. It is good.

When the operation lever 56 is positioned in the separation channel 26 and the operation lever 20 is rotated about the rotation center axis 16 in the opposite direction as in the engagement, the operation protrusion 56 is the guide channel. Guided at 24. In the process of guiding the manipulation protrusion 56 along the guide channel 24, relative movement occurs between the first connector 40 and the second connector 50, and a separation operation is performed. When the first and second connectors 40 and 50 are separated to the state of FIG. 5 by the opposite direction rotation of the manipulation lever 20, the coupling between the terminals is separated. In this state, the operator may separate the first connector 40 from the second connector 50 by hand.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

For example, in the present embodiment, there is an operation protrusion 56 on the inner surface of the second connector 50, but the operation protrusion is located on the outer surface of the second connector 50, and the operation lever 20 is Located on the outer surface of the second connector 50 may be coupled to and separated from the first connector 40 and the second connector 50. At this time, the operation lever 20 is supported by the restoring member 30 that provides an elastic force in the center direction at both ends of the rotation center shaft 16 and stopper so as not to enter the center of the rotation center shaft 16 more than a predetermined amount ( (Not shown).
