Description

Lever-type connector assembly < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a lever-type connector assembly for coupling between two connectors using a lever.

Generally, a connector assembly is one in which a pair of connectors are coupled to each other to perform an electrical connection of terminals installed in each of them. As the number of terminals installed in the connector increases, the magnitude of the force required to perform the coupling between the connectors also increases. Therefore, a lever-type connector is used in which a plurality of terminals are installed in the connector, wherein the connectors are coupled to each other by the lever principle using levers.

FIG. 1 is a perspective view showing a configuration of a lever-type connector assembly.

For convenience, the connector on which the lever 3 is mounted is referred to as a first connector 2, and the connector coupled to the first connector 2 is referred to as a second connector 5.

The first connector 2 is coupled to a door side of the vehicle, and a plurality of terminals (not shown) are installed therein. As shown in FIG. 1, the lever 3 is rotatably installed around the rotation axis 2 'of the first connector 2. As shown in FIG. More precisely, the lever 3 is provided with a rotating hole 3a so that the rotating hole 3a is penetrated by the rotating shaft 2 '.

A coupling channel 3 'is formed on the outer surface of the lever 3. The coupling channel 3 'guides the coupling boss 5 "of the second connector 5 to be described later and guides the coupling of the first and second connectors 2, 5.

The second connector 5 is installed on the body side of the vehicle, and is more precisely engaged with the first connector 2 in a state of being fixed to a panel (not shown) of the vehicle. A plurality of terminals (not shown) to be coupled to the terminals of the first connector 2 are provided in the second connector 5 and the first connector 2 is provided in the second connector 5 An insertion space 5 'to be installed is formed. A coupling boss 5 "guided by the coupling channel 3 'is formed on the inner surface of the insertion space 5'.

When the operator first pushes the first connector 2 into the insertion space 5 'of the second connector 5, the operation of joining the first and second connectors 2, The coupling boss 5 '' of the second connector 5 is inserted into the coupling channel 3 'of the first connector 3. When the lever 3 is rotated in this state, the coupling channel 3' The engaging boss 5 "is guided to engage the first and second connectors 2, 5.

However, the above-described conventional connector assembly has the following problems.

Prior to the engagement of the first connector 2 with the second connector 5, the lever 3 must be maintained at an appropriate angle with the first connector 2. More precisely the angle of the lever 3 so that the inlet 3 '' of the coupling channel 3 'of the lever 3 faces the coupling boss 5' 'of the second connector 5, . This allows the coupling bosses 5 '' of the second connector 5 to be naturally inserted into the coupling channel 3 'in the course of coupling the first and second connectors 2, It is for this reason.

However, since the lever 3 is rotatably coupled to the first connector 2, the lever 3 can be arbitrarily rotated by an external force applied during assembly or transportation, It is necessary to adjust the angle of the lever 3 prior to assembling the first and second connectors 2 and 5, thereby complicating the operation.

In order to solve this problem, the lever 3 may be fixed to the second connector 2 through a structure such as a fixing protrusion (not shown). In this case, the first and second connectors 2 5, the lever 3 needs to be released from the first connector 2, thereby increasing the number of workpieces.

When the first connector 2 and the second connector 5 are coupled to each other in a narrow place such as between the vehicle door and the vehicle body, the engaging boss 5 '' of the second connector 5 There is a problem that it is difficult to visually confirm whether or not it is correctly inserted into the coupling channel 3 'of the lever 3.

If the lever 3 is rotated in a state in which the engaging boss 5 '' is not correctly inserted into the coupling channel 3 ', the lever 3 is moved to the second connector 5' Since the first connector 2 is rotated without being pulled toward the first connector 2, it is fixed to the first connector 2, thereby incomplete coupling occurs between the connectors.

Even if the worker senses that the first and second connectors 2, 5 are not engaged, the worker moves the lever 3 to the engagement bosses (not shown) of the second connector 5 5 '' are inserted into the coupling channel 3 'of the lever 3 and the lever 3 is rotated to connect the two connectors 2 and 5 together, the assembling work becomes very troublesome .

More precisely, the guide portion 35 'and the engaging portion 35' 'are connected to each other to form the substantially L shape. That is, when the guide protrusion 45 of the second connector 40 is hooked on the latching portion 35 '', the guide protrusion 45 is subjected to the force pulled by the lever 30 as the lever 30 is rotated . In this embodiment, the guiding portion 35 'of the guide channel 35 is formed by being inserted into the actuating plate 31, and the engaging portion 35' 'is formed through the actuating plate 31 , The guide portion 35 'may also be formed through the actuating plate 31.

A rotation slot 36 is formed in the actuating plate 31. The rotation slot 36 is a portion through which the rotation protrusion 16 of the first connector 10 is inserted and is formed through the actuating plate 31 as shown in FIG.

More precisely, the rotation slot 36 includes a seating portion 36a ', 36b' extending in a direction orthogonal to the coupling direction of the first connector 10 and the second connector 40, ', 36b' 'extending in an oblique direction from the center of rotation 36a' ', 36b' '. The seating portions 36a 'and 36b' serve to prevent the rotation of the lever 30 due to the rotation protrusion 16 being seated in the seating portions 36a 'and 36b' And the projection (16) is moved along the inside thereof to guide the rotation of the lever (30). In the present embodiment, the rotary parts 36a '' and 36b '' are formed along a straight line, but they may be curved.

The rotation slot 36 is provided with two pairs 36a and 36b on the one actuating plate 31. The two rotation slots 36a and 36b correspond to the two rotation projections 16a and 16b of the first connector 10. The two rotation slots 36a and 36b are spaced apart from each other with the guide channel 35 therebetween.

The operation plate 31 is provided with a fastening piece 37. The fastening piece 37 is a part of the fastening piece 15 of the first connector 10 which is cantilevered and is elastically deformable in a direction away from the inner surface of the first housing 11. [ That is, the fastening piece 37 is inserted into the fastening hole 15 when the lever 30 is rotated so that the first connector 10 and the second connector 40 are fully engaged, It is prevented from rotating again in the opposite direction.

The actuating plate 31 is provided with a tongue piece 38. Before the first connector 10 and the second connector 40 are engaged, the lever 30 is moved to the first connector 10 at a predetermined angle And is elastically deformable as shown in the drawing.

2, the fixed piece 38 includes a connection bridge 38a connected to the actuating plate 31 and an inner surface of the first connector 10 from the distal end of the connection bridge 38a. And a protruding portion 38b protruding in the direction of FIG. The fixed piece 38 has a substantially cantilevered shape so that the tip of the protruding portion 38b is elastically deformed toward the fixing hole 15 of the first connector 10.

That is, the projecting portion 38b of the fixed piece 38 is inserted into the fixing hole 15 of the first connector 10 so that the lever 30 can be fixed to the first connector 10 will be.

At this time, as shown in FIG. 3, the protruding portion 38b is formed so that the area of the cross section becomes smaller toward the protruding tip end. More precisely, the inclined surfaces A, A ', B and B' are formed on the outer surface of the protruding portion 38b so that the protruding portion 38b is relatively easily inserted into the fixing hole 15 of the first connector 10 And also to be able to escape. This is because the lever 30 is fixed to the first connector 10, but the force for releasing the lever 30 is not increased.

In the present embodiment, the shape of the projecting portion 38b is substantially quadrangular pyramidal. That is, all four surfaces surrounding the protruding portion 38b are inclined. This is because when the lever 30 is assembled to the first connector 10, the inclined plane A positioned at the lower end of the protrusion 38b elastically deforms the fixed piece 38, So that it can be inserted into the fixing hole 15. At the same time, the tongue piece 38 is easily elastically deformed by the inclined surface B formed on the left side of the protrusion 38b in the process of releasing the tongue of the lever 30, 15). Of course, the shape of the projecting portion 38b is not limited to a quadrangular pyramid, and may be formed in a frustum or hemisphere shape.

At this time, the tongue piece 38 and the fastening piece 37 are spaced apart from each other along the rotation path of the lever 30. This is because when the lever 30 is rotated in a state in which the protruding portion 38b of the fixed piece 38 is hooked on the fixing hole 15, the protruding portion 38b comes out of the fixing hole 15, 37) can be hooked to the fixing hole (15).

The operating plate (31) of the lever (30) is provided with a hook piece (39). The hooking piece 39 is hooked on one edge of the channel 13 of the first connector 10 to adjust the position of the lever 30. [ To this end, hooking protrusions 39 'protrude from the tip of the hooking piece 39.

The hooking piece 39 extends in a direction orthogonal to the direction in which the first connector 10 and the second connector 40 are coupled to each other and has a cantilever shape like the separation preventing piece 33, 39, a deformation space 39 '' for elastic deformation of the hooking piece 39 is formed.

Next, referring to the second connector 40, the second connector 40 is a device that is coupled with the first connector 10 to be electrically connected to each other. The skeleton of the second connector 40 includes a second housing 41, . As shown in FIG. 2, the second housing 41 has a substantially hexahedral shape and is made of an insulating material such as synthetic resin. A terminal accommodating portion 41 'is formed in the second housing 41 and a terminal (not shown) is mounted on the terminal accommodating portion 41'. At this time, the terminal accommodating portion 41 'is provided with a lance (not shown) so that the terminal is fixed by hanging.

A guide protrusion 45 is provided on the outer surface of the second housing 41. The guide protrusion 45 is inserted by the guide channel 35 of the lever 30 to guide the movement of the second connector 40 and to receive the rotational force of the lever 30, 40 can be moved in the direction of the first connector 10. The guide protrusions 45 are provided on both outer sides of the second housing 41, respectively.

A pressing piece 47 is provided on the outer surface of the second housing 41. The pushing piece 47 presses the inclined surface 31 'formed on the actuating plate 31 of the lever 30 to move the lever 30 to a rotatable position.

More precisely, the pushing piece 47 is formed in a cantilever shape on the outer surface of the second housing 41 so that the second connector 40 is inserted into the insertion space S of the first connector 10 The lever 30 is moved in a direction orthogonal to the moving direction of the second connector 40 by pressing the inclined surface 31 'of the operating plate 31 elastically. Reference numeral 47 'corresponds to a tip substantially in contact with the inclined surface 31' of the actuating plate 31.

The second housing 41 is provided with a fixed releasing portion 39. The fixing part 39 is inserted into the hooking channel 13 of the first housing 11 so that the hooking piece 39 of the lever 30 hooked to one end of the hooking channel 13 Thereby releasing the hooking piece 39 from being hooked.

More precisely, before the pushing piece 47 pushes the inclined surface 31 'of the lever 30 to move the lever 30, the fixed state of the lever 30 It will be released first.

A second terminal support (50) is inserted into the support hole (48) formed at one side of the second housing (41) to support the terminal. The second terminal support portion 50 is provided with a support protrusion 55 so that the terminal can be more firmly fixed to the terminal accommodating portion 41 'by hanging one side of the terminal. Reference numeral 52 denotes a handle.

Hereinafter, the operation of the lever-type connector assembly according to the present invention will be described in detail with reference to the drawings.

FIGS. 4 to 7 illustrate a process of assembling the first connector and the second connector, which constitute an embodiment of the present invention, in an assembly flow chart.

As a result, the first connector 10 and the second connector 40 are assembled. First, the operator assembles the lever 30 to the first connector 10. That is, the rotation protrusion 16 of the first connector 10 is inserted into the rotation slot 36 formed in the operation plate 31 of the lever 30.

At this time, the rotation protrusion 16 is seated on the seating portions 36a 'and 36b' of the rotation slot 36. [ The rotation protrusion 16 is hooked on the inner surface of the seating portions 36a 'and 36b' extending in the direction orthogonal to the coupling direction of the first connector 10 and the second connector 40, It can not be done.

At the same time, the projecting portion 38b of the tongue piece 38 formed on the lever 30 is hooked on the fixing hole 15 of the first connector 10. In this case, the lever 30 is temporarily fixed to the first connector 10 at an angle. The open end of the guide portion 35 'of the guide channel 35 of the lever 30 is directed toward the guide protrusion 45 of the second connector 40.

The hooking piece 39 of the lever 30 is hooked on one edge of the hooking channel 13 of the first connector 10. 4, the movement of the lever 30 in the left and right directions is prevented by the hooking piece 39, and the rotation of the lever 30 is prevented by the tongue piece 38. Such a state is shown in Fig.

Accordingly, even if the assembly composed of the first connector 10 and the lever 30 is transferred or stored, the lever 30 is fixed to the first connector 10 and is prevented from rotating arbitrarily due to external force .

Next, the operator assemble the second connector (40) to the first connector (10). The second connector 40 is inserted into the insertion space S of the first connector 10 and the guide protrusion 45 of the second connector 40 is inserted into the insertion space S of the first connector 10, Is inserted into the guide portion 35 'of the channel 35.

At this time, since the guide channel 35 is opened toward the guide protrusion 45 due to the tightness of the lever 30, the operator does not need to adjust the angle of the lever 30, 40 may be simply pushed toward the first connector 10.

When the guide protrusion 45 is moved along the guide channel 35, the securing portion 49 of the second connector 40 is engaged with the hook protrusion 39 of the hook piece 39 of the lever 30 39 '). This is possible because the unlocking portion 49 moves along the hooking channel 13 of the first connector 10 and pushes the hooking protrusion 39 'formed on the tip of the hooking piece 39 precisely .

The hooking protrusion 39 'of the hooking piece 39 is pressed and fixed by the unlocking portion 49 of the second connector 40. At the same time, The lever 47 comes into contact with the inclined surface 31 'of the lever 30 while moving along the direction of arrow 1 in Fig. This is shown in Fig.

In this state, when the operator further pushes the second connector 40 toward the first connector 10, the tip end of the pushing piece 47 pushes the inclined surface 31 'of the lever 30 , So that the lever 30 is moved in the direction of arrow (2) in FIG. At this time, since the lever 30 is pressed by the elastic force of the pressing piece 47, it can be moved more reliably.

In this process, the protruding portion 38b of the fixed piece 38 naturally escapes from the fixing hole 15. This is because the tongue piece 38 of the lever 38 can be relatively easily removed from the fixing hole 15 due to the inclined surface B formed on the outer surface of the fixing hole 15 in the state of being inserted into the fixing hole 15 .

When the lever 30 is moved, the rotation protrusion 16 of the first connector 10 comes out of the seating portions 36a 'and 36b' of the rotation slot 36 of the lever 30, ', 36b' ') and is rotatable. At the same time, the guide protrusion 45 of the second connector 40 moves along the guide channel 35 of the lever 30 and is positioned at the latching portion 35 ''. This is shown in FIG.

Next, the operator rotates the lever 30 to fully engage the first connector 10 and the second connector 40. More precisely, the operator presses the connecting plate 32 of the lever 30 in the direction of the arrow ③ of FIG. 6, thereby rotating the lever 30. When the lever 30 is rotated, the guide protrusion 45 of the second connector 40 hooked on the hook 35 '' of the guide channel 35 is rotated by the hook 35 ' And as a result, the second connector 40 is moved in the direction of the first connector 10. As described above, since the first connector 10 and the second connector 40 are coupled by the rotational force of the lever 30, the coupling force is reduced as compared with the direct coupling between the connectors.

When the lever 30 is fully rotated, the fastening piece 37 of the lever 30 is hooked on the fixing hole 15 of the first connector 10 so that the lever 30 can be moved back It is prevented from rotating. Therefore, the state in which the first connector 10 and the second connector 40 are coupled can be firmly maintained.

In contrast, when the first connector 10 and the second connector 40 are separated from each other, the operator rotates the lever 30 in the opposite direction to fix the fixing hole 15 of the first connector 10, So that the fastening piece 37 of the lever 30 is separated. When the lever 30 is rotated as described above, the guide protrusion 45 of the second connector 40 is received by the engaging portion 35 '' of the lever 30, Is moved in a direction away from the first connector 10.

In this state, the operator completely pulls the first connector 10 and the second connector 40 in a direction away from each other.

Finally, the operator pushes the lever 30 to the right with reference to Fig. 6 so that the lever 30 is in the state shown in Fig. That is, the lever 30 is fixed to the first connector 10 again.

It is to be understood that the invention is not limited to the disclosed embodiments, but is capable of many modifications and alterations, all of which are within the scope of the appended claims. It is self-evident.
