Description

Connector and connector assembly {Connector and connector assembly having the same}

The present invention relates to connectors and connector assemblies.

A connector is made by installing one or more terminals of conductive material in a housing of insulating material. The connector may form one assembly by being combined with the counterpart connector, and may perform electrical connection. To make an electrical connection between connectors, the terminals must be coupled to each other.

In the coupling of the connectors, the connectors must move in a straight line in a direction in which the connectors get closer to each other as much as the coupling length at which the terminals are coupled, and additionally, a distance for coupling between the housings of each terminal is required before coupling the terminals. However, when the connectors constituting the connector assembly are to be coupled to each other in a narrow space, although the coupling length between the terminals can be provided, the distance and space for coupling between the housings and the space for the operator's work are not properly secured. There are cases where it doesn't. In this case, there is a problem in that the operation of coupling the connectors to each other becomes very cumbersome and complicated.

And, when the operator couples the connectors to be coupled to each other, the connectors are placed on a straight line and tried to be combined, but there is a problem in that a lot of deviation occurs depending on the skill level of the operator. If the connectors coupled to each other are not coupled in a straight line, excessive force is applied to the housing or terminal, and in severe cases, damage may occur.

Hereinafter, the use of the connector and connector assembly according to the present invention having the above configuration will be described in detail.

In the present invention, the first connector 10 and the second connector 30 may be coupled to each other in a state where the first guide cap 20 and the second guide cap 40 are positioned to face each other. However, the connector assembly of the present invention can be usefully utilized when the first connector 10 and the second connector 30 do not come close to each other on a straight line and are coupled at a predetermined inclination angle.

That is, as shown in FIG. 9, the direction of arrow A, which is the direction in which the first connector 10 moves, and the direction of arrow A', which is the direction in which the second connector 30 moves, are not on a straight line. The extension line may have a predetermined angle.

The first connector 10 and the second connector 30 are adjacent to each other so that the first guide cap 20 and the second guide cap 40 can be coupled to each other. At this time, the coupling boss 42 may be inserted into the coupling hole 22 and coupled first. At the same time as this combination, some of the first positioning ribs 24 and the second positioning ribs 44 may also be adjacent to each other. As shown in FIG. 9, the first positioning rib 24 and the second positioning rib 44 are adjacent to each other so that the relative rotation between the first guide cap 20 and the second guide cap 40 occurs. This can be prevented from happening arbitrarily beyond a certain point. Any relative rotation angle between the first guide cap 20 and the second guide cap 40, provided that the distance between the first positioning ribs 24 is narrower than that in the illustrated embodiment. can be reduced that much.

As such, when the first positioning rib 24 and the second positioning rib 44 are in contact with each other, the relative rotation between the first guide cap 20 and the second guide cap 40 is increased by a certain force or more. , that is, it can be caused by the force applied by the operator.

As shown in FIG. 9 , after the first connector 10 and the second connector 30 are coupled in an inclined state, the operator attaches the first guide cap 20 of the first connector 10 to the coupling. By rotating the boss 42 as the center, the state of FIG. 11 can be achieved. In the state of FIG. 11 , the front end of the terminal installation portion 14 of the first connector faces the second inner space 36 of the terminal installation portion 34 of the second connector 30 .

11, when the operator moves the first terminal installation part 14 of the first connector 10 in the direction of arrow B, the first terminal installation part 14 moves the second terminal installation part 14 of the second connector 30. While entering the second inner space 36 of the terminal installation part 34, the terminals of the first connector 10 and the second connector 30 can be coupled. Such a state is shown in FIG. 4 .

Meanwhile, when the first connector 10 and the second connector 30 are relatively rotated around the coupling boss 42, the guide bar 46 may move along the guide channel 28. . As the guide bar 46 moves along the guide channel 28 in this way, the relative rotation between the first connector 10 and the second connector 30 can be accurately guided.

During this operation, the first terminal installation part 14 may be fixed at different positions within the first housing 12 . First, in a state before the first connector 10 and the second connector 30 are coupled, the front part of the first terminal installation part 14 should not protrude from the guide box part 26. This is to prevent the first terminal installation part 14 from interfering with rotation between the first guide cap 20 and the second guide cap 40 . In this state, as can be seen in FIG. 8 or 10, the first coupling protrusion 17 is hooked to the first coupling hole 29, and the second coupling protrusion 18 is the guide box portion 26 ) is hung at the rear end of the

Then, when the first terminal installation part 14 moves relatively forward from the first connector 10 and enters the second inner space 36 of the second terminal installation part 34 of the second connector 30 3, the first coupling protrusion 17 may be coupled to the second coupling hole 38 of the second connector 30. The second coupling protrusion 18 becomes hooked on the first coupling hole 29 of the first connector 10 .

Next, separating the first connector 10 and the second connector 30 from each other will be described. First, the first terminal installation part 14 protrudes from the rear of the first housing 12. To this end, the coupling lever 16 is elastically deformed by pressing the coupling lever 16 in the direction of the arrow C shown in FIG. 3 . When the coupling lever 16 is pressed in the direction of the arrow C, the first coupling protrusion 17 is separated from the second coupling hole 38, and the second coupling projection 18 is the first coupling hole 29 ) is separated from Accordingly, the first terminal installation part 14 can protrude to the rear of the first housing 12 and move.

In this state, the first connector 10 and the second connector 30 are combined with the coupling boss 42 and the coupling hole 22, and the first positioning rib 24 and the second positioning rib (44) are coupled by interlocking. When a worker applies force to each of the connectors 10 and 30 in a direction in which the first connector 10 and the second connector 30 are separated, the first connector 10 and the second connector 30 are separated. can
