Description

Connector {Connector}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a connector having a protection plate for protecting a terminal in a housing.

Generally, a connector is composed of a connector housing and a terminal, and is widely used for a power supply circuit such as a washing machine, a refrigerator, or an automobile. When the above connector is used in these electric / electronic devices, since a plurality of parts can be assembled individually and then inserted into a final product, not only device manufacturing but also maintenance work can be greatly simplified.

At this time, the connector is 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 and electrically connected. That is, the connector is electrically connected or disconnected as it is attached to or detached from the mating connector.

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

In the process of joining the terminal of the connector and the mating terminal of the mating connector, since the terminal is formed to have a very long length compared with the width thereof, the terminal may be easily bent or severely damaged There is. Particularly, when a plurality of terminals are inserted into the connector housing, the coupling between the terminals becomes more difficult.

And the terminal remains exposed before the connector is engaged with the mating connector. If the terminal is exposed to the outside, the terminal tends to be damaged during storage or transportation.

Particularly, when a component such as a clip is inserted into the connector housing while the terminal is installed in the connector housing, the terminal may be damaged by carelessness of the operator.

In addition, a foreign substance may be inserted into the connector housing to interfere with the electrical connection between the terminal and the mating terminal. That is, when the two connectors are coupled with each other in a state where the foreign substance is inserted into the connector housing, electrical connection between the two terminals is not stable.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and an object of the present invention is to align the tip of a terminal in a process of coupling between two connectors.

It is another object of the present invention to prevent foreign matter from being inserted into the connector housing during the storage and transportation of the connector, and to prevent damage to the terminal.

According to an aspect of the present invention for achieving the above object, the present invention provides an electronic apparatus including a terminal mounting portion formed with an internal space into which a mating connector is inserted, and a terminal hole formed therein, A connector housing in which a fixing rib is formed so as to protrude from the terminal mounting portion toward the mating connector, and a plate coupling hole is formed in the fixing rib at a position closer to the terminal mounting portion than the mounting hole and the mounting hole; A through hole is formed in the inner space so as to be movable in the connector housing so that the tip of the terminal is selectively exposed, a coupling slit through which the fixing rib is inserted is formed in the through hole, And a protrusion protruding from the protrusion so that the protrusion and the protrusion are protruded from the coupling slit. The protrusion protrudes from the protrusion to the connector housing.

The fixing rib has a first fixing rib formed with a long hole extending in a direction in which the protection plate is coupled, A guide channel formed at one end of the first fixed rib and extending in a direction opposite to the first fixed rib, the guide channel having one end opened toward the coupling protrusion at a tip end thereof, And a second fixing rib on which a coupling hole is formed.

Wherein the connector housing is formed with a fixing hole so that an auxiliary coupling protrusion is formed at a position corresponding to the fixing hole at an edge of the protection plate so that the coupling protrusion is inserted into the plate coupling hole, A coupling protrusion is inserted to fix the protection plate to the connector housing.

A guide rib is formed on the inner surface of the connector housing so as to protrude toward the inner space. The guide rib is disposed on the protection plate, and a guide groove for guiding movement of the protection plate is formed.

A handle portion is formed on a surface of the protection plate opposite to a surface facing the terminal mounting portion.

In the present invention, since the protective plate aligns the terminal positions in the process of coupling the mating connector to the inside of the connector housing, the coupling between the terminals can be accurately performed. Therefore, it is possible to prevent an external force from being applied to the terminal.

In the present invention, the protection plate selectively shields the inner space of the connector housing to protect the terminal before the mating connector is coupled. Therefore, since the foreign matter is prevented from being inserted into the inside of the connector housing, the operational reliability of the connector is improved.

Particularly, in the present invention, a protective cover inserted into the connector housing is formed with a peeling projection, and a connector channel is formed in the connector housing so that the peeling projection is hooked. Accordingly, since the protection plate is prevented from being separated from the connector housing before the mating connector is coupled into the connector housing, the workability is improved.

Hereinafter, preferred embodiments of the connector according to the present invention having the above-described structure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of a connector according to a preferred embodiment of the present invention. Fig. 2 is a perspective view of a protection plate constituting an embodiment of the present invention. Fig. 3a and Fig. An example of the essential part is shown in a partial cross-sectional perspective view.

As shown in these drawings, the external appearance and skeleton of the connector 10 are formed by the connector housing 20. The connector housing 20 is formed in a substantially hexahedral shape and is made of an insulating material such as synthetic resin.

An internal space 21 is formed in the connector housing 20. The inner space 21 is formed such that one side thereof is opened in a direction in which a mating connector (not shown) is inserted. The mating connector is inserted into the inner space 21.

The terminal space (22) is formed in the inner space (21). The terminal mounting portion 22 allows a terminal (not shown) to be inserted into the internal space 21 and to maintain a fixed state.

A plurality of terminal holes 22 'are formed in the terminal mounting portion 22. The terminal hole 22 'is formed to pass through the connector housing 20 in the front-rear direction. A terminal is inserted into the terminal hole 22 '.

The terminal mounting portion 22 is formed with a fixed rib 23. The fixing ribs 23 are formed to protrude toward the mating connector. More specifically, the fixing ribs 23 are formed to protrude from the terminal mounting portion 22 toward the protection plate 40, which will be described below. The fixed ribs 23 are spaced apart from each other by a predetermined distance, and a pair of the fixed ribs 23 are formed side by side. The fixing ribs 23 are formed in a substantially plate shape. The fixing ribs 23 serve to assemble or fix the protection plate 40 to the connector housing 20.

The fixed rib 23 includes a first fixed rib 24 and a second fixed rib 26. The first fixing ribs 24 extend toward the protection plate 40. The first fixing ribs 24 are inserted into the first fitting slits 44a of the protection plate 40 to be described below.

The first fixing rib (24) is formed with a gluing channel (25). The gashing channel 26 is a portion where the gashing projection 45 of the protection plate 40 to be described below is hooked. 3A, the protrusion 45 of the protection plate 40 is hooked on the glued-attaching channel 25 so that the protection plate 40 is assemble to the connector housing 11. As shown in FIG. The glued-attaching channel 25 is elongated in a direction in which the protection plate 40 is coupled. This is to make the gobulation projection 45 movable in the process of joining the protection plate 40 to the fixed rib 23.

The first fixing ribs 24 are formed with guide slits 25 '. The guide slit 25 'is formed to extend from the tip of the first fixing rib 24 toward the gob alignment channel 25. The guide slit 25 'is formed so as to be recessed at a position facing the gob-shaped projection 45. The guide slit 25 'serves to guide the gashup projection 45 to smoothly engage the gashup channel 25.

The second fixing ribs 26 extend in a direction perpendicular to the direction in which the first fixing ribs 24 extend. That is, the second fixing ribs 26 extend from opposite ends of the first fixing ribs 25 in opposite directions. The second fixing ribs 26 are portions to be inserted into the second fitting slits 44b of the protection plate 40.

A guide channel (27) is formed in the second fixed rib (26). The guide channel (27) is formed to open at one side toward the tip of the second fixing rib (26). The guide channel 27 is formed to extend from the distal end of the second fixing rib 26 toward the terminal mounting portion 22. The guide channel 27 serves to guide the protection plate 40 to be moved to the terminal mounting portion 22 when the protection plate 40 is inserted into the internal space 21. [ The coupling protrusion 46a formed on the protection plate 40 is positioned in the guide channel 27. [

The plate fixing hole 28 is formed through the second fixing rib 26. The plate coupling hole 28 is formed at a position adjacent to the guide channel 27. The plate coupling hole 28 is formed at a position nearer to the gobal alignment channel 25 with respect to the terminal mounting portion 22. The plate engaging hole 28 is selectively engaged with the first engaging projection 45 of the protection plate 40. That is, as shown in FIG. 3B, the coupling protrusion 46a of the protection plate 40 is hooked on the plate coupling hole 28, so that the protection plate 40 aligns the position of the terminal.

The connector housing 20 has a fixing hole 29 formed therein. The pair of fixing holes 29 are formed to be spaced apart from each other by a predetermined distance. The fixing hole 29 is hooked on the auxiliary engaging projection 47 of the protection plate 40 to be described below. That is, the coupling protrusion 46a of the protection plate 40 is engaged with the plate coupling hole 28, and the auxiliary coupling protrusion 47 is engaged with the fixing hole 29, And is fixed to the housing 20.

A guide rib 30 is formed in the connector housing 20. The guide ribs 30 are formed to protrude from the inner surface of the connector housing 20 toward the inner space 21. The guide ribs 30 are elongated in the coupling direction of the mating connector. That is, the guide ribs 30 extend from the opening of the inner space 21 to the terminal mounting portion 22. The guide ribs 30 are inserted into the guide grooves 50 of the protection plate 40 in the inner space 21. A plurality of guide ribs 30 may be formed according to design conditions.

The connector housing (20) is provided with a protection plate (40). The protective plate 40 is formed in a substantially plate shape and has a shape corresponding to the cross section of the inner space 21. [ The protection plate 40 is formed of an insulating material in the same manner as the connector housing 20, and is elastically deformable due to its material and shape. The protection plate 40 moves from the internal space 21 toward the terminal mounting portion 22. The protection plate 40 serves to align the position of the terminal and to prevent foreign matter from flowing into the interior space 21.

A plurality of through holes 42 are formed in the protection plate 40. The through hole 42 is formed so as to pass through a position corresponding to the terminal hole 22 'of the connector housing 20. The through holes 42 are formed in a number corresponding to the number of the terminals, through which the terminals of the terminals selectively pass.

A coupling slit 43 is formed in the protection plate 40. The engaging slit 43 is composed of a first engaging slit 44a and a second engaging slit 44b. The first engaging slit 44a and the second engaging slit 44b are formed to correspond to the first fixing ribs 24 and the second fixing ribs 26, respectively. The first engaging slit 44a and the second engaging slit 44b are portions into which the first fixing ribs 24 and the second fixing ribs 25 are inserted, respectively.

The protective plate 40 is formed with a protrusion 45 for protrusion so as to be positioned on the first engagement slit 44a. The gashup projection (45) is a portion inserted into the gashing channel (25). 3A, the protective plate 40 is assembled to the connector housing 20 by inserting the protrusion 45 into the gluing channel 25. As shown in FIG.

A coupling protrusion 46a is formed on the protection plate 40 so as to be positioned at the second coupling slit 46a. The coupling protrusion 46a is formed at a position corresponding to the plate coupling hole 28. [ The engaging projection 46a is a portion to be inserted into the plate engaging hole 28. [ That is, as shown in FIG. 3B, the coupling protrusion 46a is engaged with the plate coupling hole 28, so that the protection plate 40 is fixed to the connector housing 20.

An auxiliary coupling protrusion (47) protrudes from the edge of the protection plate (40). The auxiliary coupling protrusion 47 is a portion inserted into the fixing hole 29. The auxiliary coupling protrusion 47 is formed at a position corresponding to the fixing hole 29. The auxiliary coupling protrusion 47 is inserted into the fixing hole 29 at the same time that the coupling protrusion 46a is inserted into the plate coupling hole 28 so that the protection plate 40 is inserted into the connector housing 20 .

A deformation slit 48 is formed in the protection plate 40. The deformed slit 48 is formed at a position adjacent to the second engaging slit 44b. The deformed slit 48 is elongated in a direction parallel to the longitudinal direction of the second engaging slit 44b. The deformed slit 48 provides a space for elastic deformation of the periphery of the engaging projection 46a when the protection plate 40 is moved toward the terminal mounting portion 22 by the mating connector.

A handle 49 is formed on a surface of the protection plate 40 opposite to the surface facing the terminal mounting portion 22. [ The handle 49 is formed to protrude from the protection plate 40. The handle 49 is a portion gripped by an operator and pulls the hand grip 49 from the connector housing 20 in a direction in which the protection plate 40 is detached.

A guide groove 50 is formed in the protection plate 40. The guide groove 50 is formed at a position corresponding to the guide rib 30. In the guide groove 50, the guide ribs 30 are positioned to guide the movement of the protection plate 40.

Hereinafter, a method of assembling the connector housing and the protection plate according to the present invention will be described in detail with reference to the drawings.

FIG. 4A is a perspective view showing a state where a protection plate is assembled to a connector housing according to the present invention, and FIG. 4B is a perspective view showing a state where a protection plate is fixed to a connector housing according to the present invention.

The operator assists the protection plate 40 to the connector housing 20 before the connector 10 and the mating connector are coupled to each other. That is, the protection plate 40 is gripped and inserted into the internal space 21 of the connector housing 20.

When the protection plate 40 is inserted into the inner space 21, the guide ribs 30 are positioned in the guide groove 50 to guide the movement of the protection plate 40.

When the protection plate 40 is inserted into the inner space 21, the first and second fixing ribs 24 and 26 are inserted into the first and second coupling slits 44a and 44b, respectively, And the engaging projection 46 is inserted into the guide channel 27. At the same time, the engaging projection 46a is positioned in the guide channel 27. [ 4A, the protection plate 40 is assembled to the connector housing 20. As shown in FIG. At this time, only a part of the tip of the terminal protrudes from the auxiliary plate 40.

The auxiliary projecting plate 45 is located on the coagulation channel 25 so that the auxiliary plate 40 is prevented from being separated from the connector housing 20 in the direction of the arrow A shown in FIG.

Then, the mating connector is coupled to the connector (10). That is, the operator pushes the mating connector into the interior space 21. At this time, the gobal projection 45 is moved along the gobal alignment channel 25 and the engaging projection 46a is moved along the guide channel 27 so that the protection plate 40 is guided by the terminal mounting portion 22 .

When the mating connector starts to be coupled to the connector 10, the protection plate 40 is guided by the guide ribs 30 and is moved to the terminal mounting portion 21. Accordingly, the protection plate 40 can be moved smoothly without any clearance or twisting in the process of moving toward the inner space 21 of the connector housing 20.

At the same time, when the protection plate 40 is moved toward the inner space 21, the terminals are relatively protruded. That is, the tip of the terminal completely passes through the through hole 42 of the protection plate 40 and protrudes toward the mating connector. Accordingly, the terminal and the mating terminal (not shown) of the mating connector can be electrically connected to each other.

At this time, the coupling of the terminal and the mating terminal is made easier by the protection plate 40. [ Since the respective terminals pass through the through holes 42 of the corresponding protection plate 40, they are coupled to the terminals of the mating connector in an aligned state.

When the protection plate 40 is in close contact with the terminal mounting portion 22, the coupling protrusion 46a of the protection plate 40 is inserted into the plate coupling hole 28, Is inserted into the fixing hole (29). Such a state is well illustrated in FIG. 4B.

In other words, the abutment projection 45 of the protection plate 40 is hooked to the cooperating channel 25 before the mating connector (not shown) is coupled to the connector 10, 40 from separating. In addition, since the protection plate 40 shields the internal space 21 and protects the terminal before the mating connector is coupled, foreign matter is prevented from being introduced into the internal space 21. When the mating connector is inserted into the internal space 21, the coupling protrusion 46a is engaged with the plate coupling hole 28 to align the terminal.

At this time, the deformation slit 48 of the protection plate 40 is elastically deformed in the direction of narrowing the width, and is again restored to a circular shape when the engaging projection 46a is inserted into the plate engaging hole 28. [

Next, a process of separating the protection plate 40 from the connector housing 20 will be described. The operator inserts a tool such as a jig (not shown) into the inside of the connector housing 20 to detach the coupling protrusion 46a of the protective plate 40 from the plate coupling hole 28. At this time, since the deformation slit 48 is formed in the protection plate 40, the coupling protrusion 46a can be smoothly separated from the plate coupling hole 28.

At the same time, the operator grips the handle 29 of the protection plate 40 and pulls the protection plate 40 in a direction in which the protection plate 40 is separated from the connector housing 20. [ In this case, the protection plate 40 is separated from the connector housing 20 smoothly.

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