Description

CONNECTOR AND CONNECTOR ASSEMBLY INCLUDING THE SAME}

The present invention relates to a connector, and more particularly, to a connector and a connector assembly including the same in which a pair of connectors are coupled to each other to perform electrical connection of wires.

In general, the connector is composed of a connector housing and a terminal, and is widely used in power circuits such as washing machines, refrigerators, or automobiles. The use of the connector in these electrical and electronic devices can assemble a plurality of parts separately and then insert them into the final product, which has the advantage of greatly simplifying maintenance work as well as device manufacturing.

In this case, the connectors are electrically connected to each other by being coupled with the mating connector. More specifically, as the two connectors are coupled, the terminal provided in the connector housing and the mating terminal provided in the mating connector housing are in contact with each other to be electrically connected. That is, the connector is electrically connected or released as it is detached from the mating connector.

However, the prior art as described above has the following problems.

The terminal remains exposed until the connector is engaged with the mating connector. This is to facilitate the coupling with the mating terminal in the process of mating the mating connector.

However, if the terminal is kept exposed to the outside in this way, there is a problem that the terminal is easily damaged during the storage or transport process. That is, in the state in which the terminal is exposed, another external object, for example, another terminal or an electric wire may collide with the terminal to act as an external force. In this case, there is a problem in that the terminal is damaged or bent, making it difficult to couple with the mating connector.

 In addition, when the terminal remains exposed to the outside, foreign matter such as dust may be inserted into the connector housing. In this case, there is a problem that the electrical connection between the terminal and the relative terminal is not made correctly. That is, if two connectors are coupled in a state in which foreign matter is inserted into the connector housing, the connection between the two terminals may be incomplete.

Accordingly, an object of the present invention is to solve the problems described above, and to provide a connector and a connector assembly including the same with minimized exposure of the terminal.

In addition, another object of the present invention is to adjust the exposure state of the terminal according to the coupling state of the connector and the mating connector.

According to a feature of the present invention for achieving the above object, a connector housing to form an appearance and a skeleton, the movable slot is formed on a part of the outer surface; And a terminal coupling part inserted into an inner space of the connector housing and moving along the moving slot in the inner space, wherein the inside of the connector housing is partitioned into a moving space and a coupling space by a protective plate. The protective plate is formed with at least one through hole to selectively penetrate the terminal coupled to the terminal coupling portion.

The terminal coupling portion, the hooking jaw guided by the movable slot is formed on the outer surface, the inclined surface is inclined downward in the insertion direction on the hooking jaw.

At least one locking protrusion is formed to protrude in a direction facing each other on the inner surface of the movable slot to selectively hang the hooking jaw.

The protective plate is formed at a front end portion based on the movable slot such that the terminal is exposed or unexposed as the terminal coupling portion is reciprocated along the movable slot.

The movement space is a space in which the terminal coupling portion is inserted and moved along the movement slot, and the coupling space is a space in which a part of the mating connector is inserted to be electrically coupled with the terminal.

According to another feature of the invention, the present invention is the connector; And a mating connector electrically coupled to the connector, wherein the mating connector is elastically deformable and has a mating lever formed at a position corresponding to the hanging jaw; A coupling slot formed through the center of the coupling lever and hooked to the hook jaw; And a release portion extending from the front end of the coupling lever and bent upwardly inclined.

According to the connector assembly of the present invention having such a configuration, when the hanger jaw of the terminal coupling portion is guided to the moving slot of the connector housing, the terminal coupling portion can move in the connector housing. If this connector is not coupled with the mating connector, the terminal coupling portion is moved backward to minimize the exposure of the terminal by the protection plate. On the other hand, when the connector is engaged with the mating connector, the terminal coupling portion is moved forward to sufficiently expose the terminal through the through hole of the protective plate.

Therefore, even when the connector is not coupled with the mating connector, the exposure of the terminal can be minimized to prevent foreign substances such as dust from being inserted, and the terminal can be prevented from being damaged or bent by an external force.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the connector and a connector assembly including the same according to the present invention as described above will be described in more detail.

1 is a schematic perspective view showing a configuration of a connector according to the present invention and a connector assembly including the same, FIG. 2 is a cross-sectional exploded perspective view showing the main components of the connector of FIG. The connector housing of is shown in partial plan view.

As shown in these figures, the connector assembly consists of a connector 10 and a mating connector 40 coupled thereto. In the present embodiment, the shape of the connector 10 and the mating connector 40 is not necessarily limited thereto, and many modifications are possible.

The connector 10 is composed of a connector housing 20 forming an appearance and a skeleton, and a terminal coupling portion 30 inserted into an inner space of the connector housing 20.

The connector housing 20 is formed in a substantially oval cross section. A moving slot 22 is formed on the upper surface of the connector housing 20. The movable slot 22 may be formed to have a width corresponding to the width of the hooking jaw 32 so that the hooking jaw 32 described below can be inserted through and guided stably. In the movable slot 22, as shown in Figure 3, a pair of engaging projections 24 are formed on the inner surface. The locking protrusion 24 is formed to protrude in a direction facing each other. That is, the locking protrusions 24 are formed to protrude at positions corresponding to each other. The locking protrusion 24 serves to fix both ends of the hooking jaw 32 to be fixed so that the terminal coupling part 30 does not move arbitrarily in the state of moving forward. In the illustrated embodiment, but described as having a pair of engaging projections 24 on the inner surface of the movable slot 22, but not necessarily, the length of the movable slot 22 or the size of the hanger 32 or other environment That is, two or more pairs may be configured depending on the length of the terminal 36. For example, when the length of the terminal 36 is longer than that shown in the drawing, the lengths of the movable slot 22 and the hooking jaw 32 should be correspondingly formed, and the hooking protrusion 24 is hooked. The jaw 32 should be formed to be fixed to the rear end and the front end of the movable slot 22, respectively.

In addition, the connector housing 20 is provided with a protective plate 26 for partitioning the connector housing 20 in the lateral direction. At this time, the protective plate 26 is preferably formed on the front end side of the connector housing 20 on the basis of the movable slot (22). Through holes 28 are formed in the protective plate 26. The through hole 28 is a portion through which the front end of the terminal 36 is selectively passed, and is formed in a number corresponding to the number of terminals 36. In the present embodiment, it will be described that a total of three through-holes 28 are formed side by side. In addition, the connector housing 20 has a moving space S which is inserted in the terminal coupling portion 30 and moved in the front and rear directions at the rear end of the connector housing 20, and the front end of the connector housing 20. The mating connector 40 is partially inserted to form a coupling space N that is electrically connected to the connector 10.

At least one terminal 36 is coupled to the terminal coupling part 30 and is formed in a shape corresponding to the moving space S of the connector housing 20. In this embodiment, the cross section is formed into an approximately elliptical shape. However, any shape may be used as long as it can be moved in the moving space S of the connector housing 20. Hanging jaw 32 is formed on the outer surface of the terminal coupling portion 30 to protrude. The hooking jaw 32 is inserted into the movable slot 22 when the terminal coupling portion 30 is inserted into the connector housing 20. Accordingly, the terminal coupling portion 30 is moved to the front and rear in accordance with the guide of the moving slot 22 in the moving space (S) of the connector housing 20. As described above, in the state in which the terminal coupling part 30 is inserted into the connector housing 20, the hooking jaw 32 is engaged with the coupling lever 42 of the mating connector 40 described below. The hanger 32 is formed with an inclined surface 34 to be inclined downward in the direction in which the coupling lever 42 is coupled. The inclined surface 34 serves to guide the coupling lever 42 to be easily coupled to the hanging jaw 32.

The mating connector 40 is formed in a substantially elliptical cross section of the housing, as in the shape of the coupling space (N). A mating terminal (not shown) is installed through the mating connector 40. The mating terminal is inserted into the terminal 36 coupled to the terminal coupling portion 30 is made an electrical connection.

A coupling lever 42 is provided on an outer surface of the mating connector 40. The coupling lever 42 extends in parallel in the distal direction of the mating connector 40 and is provided at a position corresponding to the hooking jaw 32. In addition, the coupling lever 42 may be elastically deformed. A coupling slot 44 is formed through the center of the coupling lever 24. The coupling slot 44 is a part which is connected to the hanging jaw 32 when the connector 10 and the mating connector 40 are coupled to each other. In addition, a release portion 46 is formed to be bent upwardly inclined upwardly in the direction in which the coupling lever 42 is coupled to the connector 20. The release part 46 serves to allow the coupling slot 44 to be easily detached from the hanger 32 while the coupling lever 42 is elastically deformed by a user pushing.

Hereinafter, the operation of the connector and the connector assembly including the same according to the present invention having the configuration as described above will be described with reference to the drawings.

4A is a side cross-sectional view showing a state in which a connector and a mating connector are separated according to an embodiment of the present invention, and FIG. 4B is a side cross-sectional view showing a state in which the terminal coupling portion of the connector is moved forward in FIG. 4A. 4c is a side cross-sectional view of the state in which the connector and the mating connector are coupled in FIG. 4b.

First, the user inserts the terminal 36 into the moving space S of the connector housing 20 in a state in which the terminal 36 is coupled to the terminal coupling part 30. At this time, the hooking jaw 32 of the terminal coupling portion 30 is inserted into the moving slot 22 of the connector housing 20.

First, the connector 10 is not coupled with the mating connector 40. In this case, the user maintains a state where the hooking jaw 32 of the terminal coupling part 30 is located at the rear end of the moving slot 22. Accordingly, the terminal coupling part 30 is located at the rear end of the connector housing 20 relatively in the moving space S, so that the terminal 36 coupled to the terminal coupling part 30 is the moving space. It is located in (S). This is because the terminal 36 is not exposed to the outside by the protective plate 26 of the connector housing 20, foreign matter is not inserted into the terminal 36 does not occur. In addition, even when the connector 10 is not coupled with the mating connector 40 while the connector 10 is stored or transported by another external force, for example, another terminal or an electric wire is inserted into the coupling space N. The protective plate 26 can prevent the collision with the terminal 36.

Next, the connector 10 and the mating connector 40 is to be coupled. In this case, as shown in FIG. 4B, the user pushes the terminal coupling part 30 in the direction of arrow A such that the terminal coupling part 30 is positioned at the front end of the moving space S. FIG. At this time, the hooking jaw 32 of the terminal coupling portion 30 is sufficiently pushed so that both ends are fixed to the engaging projection 24 formed on the inner surface of the movable slot 22. This is to assist the user when the coupling lever 42 of the mating connector 40, the hooking jaw 32 is not pushed to provide a convenience to the user and can be stably coupled. Accordingly, the terminal 36 coupled to the terminal coupling portion 30 passes through the through hole 28 of the protective plate 26 to be exposed to the coupling space N.

In this state, as shown in FIG. 4C, the connector 10 and the mating connector 40 are coupled. The coupling method starts inserting the distal end of the mating connector 40 into the coupling space (N) of the connector 10. Then, the distal end of the mating connector 40 is inserted and the lower end of the release portion 46 of the mating connector 40 is in contact with the inclined surface 34 of the hanger 32. At this time, the coupling lever 42 of the mating connector 40 is elastically deformed and the lower end of the release portion 46 is slid along the inclined surface 34. When the front end of the mating connector 40 is completely inserted into the coupling space (N), the lower end of the release portion 46 is extended to the rear end of the upper end of the hanger (32). That is, the hooking jaw 32 is seated in the coupling slot 44 of the coupling lever 42, and eventually the terminal 36 is electrically coupled with the mating terminal (not shown). As such, since the hooking jaw 32 is fixed by the locking protrusion 24, the user can easily couple the connector 10 and the mating connector 40.

Again, when the connector 10 and the mating connector 40 need to be separated from each other, the user pushes the release part 46 in the direction of arrow B, as shown in FIG. 4C. Then, when the coupling lever 42 is elastically deformed and the release part 46 is released from the hooking jaw 32 and the connector 10 and the mating connector 40 are separated, the terminal 36 and the mating terminal are also removed. Are separated together. Accordingly, in order to protect the terminal 36 coupled to the connector 10 from foreign matter and external force, as shown in FIG. 4A, the terminal coupling portion 30 is moved backwards so that the coupling space N is located. The terminal 36 which has been exposed to is positioned in the moving space S.

As such, even when the connector and the mating connector are separated, the terminal of the connector can be safely protected from foreign matter and external force.

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.
