Description

Waterproof connector and waterproof connector assembly having the same{WATERPROOF CONNECTOR AND WATERPROOF CONNECTOR ASSEMBLY HAVING SAME}

The present invention relates to a waterproof connector and a waterproof connector assembly having the same, and more particularly, to a waterproof connector comprising a plate for accurately maintaining a gap between terminals provided inside the connector and a waterproof connector assembly having the same. .

In general, the connector assembly is a connecting component that electrically connects the power source and the device, the device and the device, and the interior of the device. This connector assembly consists of a pair that can be coupled and detached, such as a male connector and a female connector. In addition, a plurality of terminals are provided inside the connector for transmitting current and signals.

In the connector assembly, the first connector and the second connector are coupled to each other to perform electrical connection. Electrical coupling of the first connector and the second connector is achieved by combining the terminals in each interior. When the number of terminals is large and thin, it is necessary that the alignment of the terminals is constant. Also, if the coupling force and separation force are large due to the large number of terminals, use the lever.

Therefore, the terminals installed inside the connector are arranged at regular intervals to facilitate coupling of the connector and not to be easily deformed by external force. Conventionally, plates have been used to keep the distance between terminals constant.

The plate maintains the distance between the terminals at the temporary coupling position of the first connector, but when inserted with the second connector, it is inserted into the first connector to move to the full coupling position, and when the second connector is detached, to the temporary coupling position. Come back again.

However, the conventional plate serves as both a front holder for fixing the lance and a plate for aligning the terminal. Therefore, the conventional plate has a problem in that it is difficult to fix the waterproof seal because the position changes by moving inside the housing of the first connector according to the coupling state of the first connector and the second connector.

In addition, since the conventional plate is directly coupled to the housing of the connector, a locking structure for fixing the plate is formed in the housing. When a locking structure is formed in the housing, moisture may flow into the connector even if a waterproof seal is coupled from the mating connector. A gap is created. Due to this structural problem, there was a problem that it was difficult to apply a waterproof structure to the plate type connector.

In addition, when the coupling between the first connector and the second connector is released, the plate moves together with the second connector to the temporary coupling position, so that the terminal inserted in the first connector cannot be supported by the plate.

A locking jaw 17 may be formed on the partition wall 16 of the terminal insertion hole 12 ′ in which the second lance 15 is installed. The locking jaw 17 may be formed by cutting a part of the partition wall 16. The front holder 20 is hung on the locking jaw 17. In order to stably support the front holder 20, the locking jaws 17 are preferably installed in a plurality of partition walls 16 constituting the edge of the terminal insert 12. The assembly state is changed according to the shape in which the front holder 20 is hung on the locking jaw 17. A locking inclined surface 17' may be formed at the tip of the locking jaw 17 that abuts the inner space 11'. The engaging inclined surface 17 ′ serves to guide the front holder 20 in the primary assembly state over the engaging jaws 17 so that the engaging jaws 17 can be easily taken over. The assembled state will be described in detail later.

A guide protrusion 18 protrudes from the terminal insertion portion 12. The guide protrusion 18 is formed to protrude toward the inner space 11', and serves to guide the front holder 20 and the plate 30.

5 and 6, the front holder 20 is seated in the inner space 11 ′ of the second housing 11. A square plate-shaped base 21 is formed in the front holder 20. A first guide hole 21b is formed in the base 21 to correspond to a cross-sectional shape of the guide protrusion 18, and a first through hole h1 through which a terminal inserted in the second housing 11 passes. A plurality of these are formed.

Referring to FIG. 5, the front holder 20 is formed such that side walls 22 surround the base 21 and both sides are opened. The side wall 22 is composed of a front side wall 22a located on the front side and a rear side wall 22b located on the back side based on the base 21. In addition, a space is formed in the front and rear of the front holder 20 based on the base 21, respectively, and the front inner space 20a is formed by the base 21 and the front side wall 22a. The rear inner space 20b is formed by 21 and the rear side wall 22b. The rear side wall 22b is inserted into the space between the terminal insertion portion 12 and the outer wall 13 of the second housing 11.

On the base 21, a locking hole 21' is formed on the back surface of the hook hook 28 to be described later, that is, on the base 21 opposite to the direction in which the hook part 28' protrudes. A locking projection 31 ′ of the plate 30 to be described later is inserted into the locking hole 21 ′, and serves to fix the short hook 28 so as not to move. This operation will be described in detail later. Meanwhile, the locking hole 21 ′ may be formed around the short hook 29 as well as the long hook 29.

A guide portion 21a protrudes from the base 21 toward the front inner space 20a. The guide portion 21a serves to guide the plate 30 to be described later.

On both sides of the front holder 20, a part of the front side wall 22a is cut so that the elastic piece 23 is formed in a cantilever shape. The elastic piece 23 extends toward the rear side wall 22b with a fixed end of the inlet edge of the front side wall 22a. The front side wall 22a on which the elastic piece 23 is formed is formed to be partially recessed toward the front inner side space 20a so that the elastic piece 23 can be elastically deformed to the outside of the side wall 22 It is prepared. The elastic piece 23 serves to maintain the position in which the plate 30 is seated on the front holder 20 according to the coupling state of the first connector 1 and the second connector 10.

A support end 24 protrudes from the elastic piece 23 toward the front inner space 20a. The support end 24 serves to support the plate 30 when the plate 30 is seated on the front holder 20. The front holder 20 is assembled to the second housing 11 with the plate 30 seated on the support end 24. In this process, a predetermined amount of pressing force acts on the plate 30. . At this time, the support end 24 supports the plate 30 so that the elastic piece 23 is not elastically deformed even if the plate 30 is subjected to a pressing force. Accordingly, the support end 24 may be formed to have a flat surface on which the plate 30 is seated, or may be formed to be inclined upward so that the tip of the support end 24 faces the plate 30. Of course, if a pressing force of a predetermined amount or more acts on the plate 30, the elastic piece 23 is elastically deformed to the outside.

A guide end 25 may be formed at the center of the support end 24 of the elastic piece 23. The guide end 25 serves to guide the plate 30 so that it can move within the front inner space 20a of the front holder 20. Through the position of the guide end 25, the operator can visually confirm the engagement state of the front holder 20 and the plate 30.

A release inclined surface 26 is formed to be inclined upward at the tip of the elastic piece 23. When the first connector 1 and the second connector 10 are completely engaged, the plate 30 comes into contact with the base 21 of the front holder 20. At this time, when the first connector 1 is separated from the second connector 10, the plate 30 should rise while elastically deforming the elastic piece 23, but the release slope 26 is the plate 30 ) To guide and elastically deform the elastic piece 23.

A plurality of hook ends 27 are formed at the edge of the inlet of the front side wall 22a. The hook end 27 protrudes toward the front inner space 20a. The hook end 27 serves to limit movement so that the plate 30 seated in the front inner space 20a does not deviate from the front holder 20.

Referring to FIG. 6, a plurality of first supporting portions 21c and second supporting portions 21d protrude toward the rear inner space 20b in the base 21. The first and second support portions 21c and 21d serve to support the terminal by fixing the lance formed in the second housing 11 so as not to move. Like the first and second lances 14 and 15 of the second housing 11, the support part may be composed of only one type of support part or two or more types of support part as necessary.

To the base 21, a hook hook 28 and a hook hook 29 protrude toward the rear inner space 20b. The short hook 28 and the long hook 29 are formed along the edge of the base 21. The short hooks 28 and the long hooks 29 protrude from the short hooks 28' and the long hooks 29', respectively, perpendicular to the extension direction of the hook hooks 28,29. The hook portions 28' and 29' are hung on the locking jaws 17 of the second housing 11, depending on the shape of the walking, the assembled state between the second housing 11 and the front holder 20. Is changed. This will be described in detail later.

Referring to FIG. 7, the plate 30 is seated in the front inner space 20a of the front holder 20. The plate 30 is formed to have one side open with a coupling space 30' therein. The coupling space 30 ′ is surrounded by a bottom surface 31 and a wall surface 32.

The bottom surface 31 has a square plate shape corresponding to the base 21 of the front holder 20. A plurality of second through holes h2 for aligning the terminals are formed on the bottom surface 31. In addition, a locking projection 31 ′ protrudes in the direction in which the front holder 20 is coupled to the bottom surface 31. The locking projection (31') is inserted into the locking hole (21') and close to the back of the hook hook (28), the hook hook (28) is elastically deformed to escape from the locking jaw (17) It serves to prevent things. The locking protrusion 31' is formed to correspond to the position and shape where the locking hole 21' is formed. Of course, the locking projection 31 ′ may support the rear surface of the long hook 29 as well as the short hook 28, but this may need to be adjusted so as not to generate excessive coupling force or release force. .

A guide hole 31a through which the guide portion 21a of the front holder 20 and a second guide hole 31b through which the guide protrusion 18 of the second housing 11 passes are penetrated on the bottom surface 31. ) Is formed to correspond to each configuration.

Concave and concave walls 33 are formed on both sides of the plate 30. The recessed wall 33 is partially recessed to correspond to the shape of the front side wall 22a of the front holder 20.

A guide slit 34 is formed in the recess wall 33. The guide slit 34 has a support end 24 and a guide end 25 of the elastic piece 23 so that the plate 30 can move within the front inner space 20a. Therefore, the guide slit 34 is formed to correspond to the shape of the support end 24 and the guide end 25.

A pressure leg 35 is formed on the wall surface 32 adjacent to the concave wall 33. The pressure leg 35 is formed by cutting a portion of the wall surface 32 but is bent toward the coupling space 30 ′ to be elastic. When the first connector 1 is inserted into the coupling space 30 ′, the pressure leg 35 is elastically deformed in a direction opposite to the portion bent toward the coupling space 30 ′, and then the first connector ( When the 1) and the second connector 10 are completely combined, the original shape is restored again, and the elastic force generated in this process is transmitted to the worker to provide a fastening feeling. In addition, since the pressure leg 35 is bent inward, the role of returning the plate 30 to the temporary engagement state by interfering with the release protrusion 3'in the process of separating the first connector 1 Do it. At this time, since the plate 30 is hooked to the hook end 27, it is not separated from the front holder 20.

Next, a process in which the first connector 1 and the second connector 10 are combined and separated will be described.

First, the front holder 20 and the plate 30 are seated in the inner space 11 ′ of the second housing 11 in a combined state as shown in FIG. 8. Thus, the state in which the front holder 20 and the plate 30 are assembled is defined as a temporary engagement state. That is, the temporary engagement state refers to a state in which the bottom surface 31 of the plate 30 is seated on the support end 24 of the elastic piece 23.

When the assembly of the front holder 20 and the plate 30 in the temporarily coupled state is seated in the inner space 11' of the second housing 11, as shown in FIG. 12, the front holder 20 The hook hook 28 and the locking jaw 17 are prevented from being inserted. Of course, the long hook 29 may interfere with the locking jaw 17, but the operation is the same, so description is omitted.

As described above, a state in which the hook portion 28 ′ of the hook hook 28 is hung on the locking jaw 17 is referred to as a primary assembly state. Referring to FIG. 9, the front holder 20 and the plate (30) maintains a temporary bonding state.

In the primary assembly state, a terminal (not shown) is inserted into the terminal insertion hole 12'. A plurality of terminals inserted into the terminal insertion hole 12' are fixed to the first lance 14 and the second lance 15, respectively.

When the assembly of the front holder 20 and the plate 30 is pressed in the primary assembly state, the short hook 28 is guided by the locking slope 17' of the locking jaw 17 and elastically deformed. In the state, the locking jaw 17 is passed. At this time, since the locking projection 31' is not in a state to support the rear surface of the hook 20, the hook 20 is formed, the tip of the hook 22 is elastically deformed to the It is possible to go over the locking jaws 17. The front hook 20 does not deviate from the second housing 11 because the hook portion 28 ′ of the hook hook 28 is hooked to the locking jaw 17. Such a state is well illustrated in FIG. 13 and is defined as a secondary assembly state.

On the other hand, in the process of moving from the primary assembly state to the secondary assembly state, the front holder 20 is continuously inserted into the second housing 11 so that the front holder 20 and the plate 30 continue Maintain temporary bonding.

Referring to FIG. 10, in the secondary assembly state, the flow of the first lance 14 and the second lance 15 by the first support portion 21c and the second support portion 21d of the front holder 20 is performed. This prevents the terminal from being supported.

In the secondary assembly state, the first connector 1 is coupled with the second connector 10, and the terminal installation part 3 of the first connector 1 presses the plate 30 to the bottom. In the process of contacting the surface 31, the plate 30 is further inserted toward the base 21 of the front holder 20. The bottom surface 31 pushes the elastic piece 23 toward the outside of the front side wall 22a by the pressing force of the first connector 1. At the same time, the pressure leg 35 is elastically deformed by the release protrusion 3'and then restored, thereby providing a feeling of fastening to the worker. 14, the state in which the bottom surface 31 of the plate 30 is in contact with the base 21 of the front holder 20 is defined as a fully coupled state. That is, when the first connector 1 in the secondary assembly state is completely coupled with the second connector 10, the front holder 20 and the plate 30 are in a fully engaged state.

As described above, when the secondary assembly is performed, the front holder 20 is fixed to the second housing 11 and the inner space 11', and only the plate 30 is fixed to the front inner space 20a. Moves within. Therefore, even if the waterproof seal 4 of the first connector 1 is inserted into the interior of the second housing 11, the front holder 20 is always fixed in position, so that the waterproof seal 4 is stable. You can keep your seat. In addition, the outer wall 13 of the second housing 11 in contact with the waterproof seal 4 does not have a fixed structure coupled with the front holder 20, and is sealed, so that moisture can flow therein. Since there is no gap, the waterproof effect by the waterproof seal 4 can be enhanced.

In the process of transitioning from the temporary coupling state to the complete coupling state, the terminals inserted into the second connector 10 are aligned while the plate 30 descends. The plate 30 first contacts terminals inserted in the second connector 10 than the first connector 1. At this time, the terminals of the second connector 10 are first aligned by the plate 30 and then contact the terminals inserted in the first connector 1, and the lever installed in the first connector 1 When (2') is rotated, the terminals of the first connector 1 and the second connector 10 are completely combined with each other, so that the coupling between the first connector 1 and the second connector 10 is completed.

On the other hand, the locking projection (31') is in contact with the back of the hook hook 28, the hook hook (28) is elastically deformed so as not to be released from the locking jaw 17 is supported in close contact. Therefore, even if an impact such as vibration or drop occurs in the second connector 10, the front holder 20 can maintain a secondary assembly state without being separated from the second housing 11.

Conversely, the process of separating the first connector 1 from the second connector 10 will be described.

When the lever 2 ′ installed on the first connector 1 is rotated in a release direction, the terminal installation part 3 is released from contact with the bottom surface 31 of the plate 30. At this time, the release protrusion 3'formed at the front end of the terminal installation part 3 is brought into contact with the pressure leg 35 of the plate 30. When the lever 2'is rotated and a force is applied in a direction to separate the first connector 1 from the second connector 10, the release protrusion 3'is hung on the pressure leg 35. While maintaining the state, the plate 30 moves together with the first connector 1 in a direction away from the base 21. When the plate 30 moves to the edge of the inlet portion of the front side wall 22a, the wall surface 32 is hooked to the hook end 27 and cannot move any more. At this time, if the force continues to act in the direction of separating the first connector 1 from the second connector 10, the release protrusion 3'elastically deforms the pressure leg 35 and moves over the plate ( 30) because the hook end (27) can no longer move, only the first connector (1) is separated from the second connector (10).
