Description

  The present invention relates to a connector having a waterproof function.

Conventionally, for example, as a technique of a connector having a waterproof function, a technique illustrated in FIGS.
As shown in FIGS. 1 to 3 of Patent Document 1, a connector 1 disclosed in Patent Document 1 is a housing having a female terminal 7 that is crimped to a terminal of a wire 6 and a waterproof plug 45 and a terminal accommodating chamber 19 inside. 2, a front holder 5 attached to the distal end side of the wall portion of the terminal accommodating chamber 19, and a packing 27 attached to the proximal end side of the wall portion of the terminal accommodating chamber 19.

  When the female terminal 7 is inserted into the terminal accommodating chamber 19 from the rear end side of the housing 2, the lance 13 is engaged with the female terminal 7. This prevents the female terminal 7 from coming off. Further, the waterproof plug 45 is brought into close contact with the inner surface of the terminal insertion hole 17. Thereby, the clearance gap between the electric wire 6 and the terminal insertion hole 17 is filled, and the water immersion to the terminal accommodating chamber 19 is prevented.

  When the connector 1 is mated with a mating connector (not shown) as a mating partner, the packing 27 attached to the wall portion of the terminal accommodating chamber 19 comes into close contact with the inner surface of the housing of the mating connector. Thereby, the clearance gap between the outer surface of the wall part of the terminal accommodating chamber 19 and the inner surface of the housing of a mating connector is filled, and the terminal accommodating chamber 19 is prevented from being flooded.

Japanese Patent Laid-Open No. 2003-45549

In the prior art, as a method for improving the waterproof performance of the connector when the connector is fitted, it is conceivable to increase the size of the packing or the waterproof plug.
When such a method is adopted and the size of the packing is increased, it is possible to increase the adhesion force when the packing is in close contact with the inner surface of the housing of the mating connector. Thereby, the clearance (clearance) between the outer surface of the wall portion of the terminal accommodating chamber and the inner surface of the housing of the mating connector can be more reliably filled to improve water tightness.
Further, when the size of the waterproof plug is increased, the adhesion force when the waterproof plug is in close contact with the inner surface of the terminal insertion hole can be increased. Thereby, the clearance gap between an electric wire and a terminal insertion hole can be filled more reliably, and watertightness can be improved.

  However, in the connector adopting the above method, since the packing attached to the wall portion of the terminal housing chamber protrudes greatly to the outside, the adhesion of the packing to the inner surface of the housing of the mating connector remains large. The mating connector must be inserted. For this reason, there has been a problem that the insertion force of the mating connector has to be increased when mated with the mating connector. For this reason, there is a problem that workability in the connector fitting work is deteriorated.

  Also, when the size of the waterproof plug is increased, the waterproof plug protrudes greatly to the outside of the electric wire, so the terminal must not be inserted into the terminal accommodating chamber while the waterproof plug is in close contact with the inner surface of the terminal insertion hole. Don't be. For this reason, in the assembly work of the connector, there has been a problem that the insertion force of the terminal has to be increased when the terminal is inserted into the terminal accommodating chamber. For this reason, there is a problem that workability in the assembly work of the connector is deteriorated.

As illustrated in FIGS. 5 and 8, when the electric wire 39 is inserted into the through hole, the space between the inner surface of the through hole and the outer surface of the electric wire 39 becomes watertight.
When the second waterproof plug 40 is fitted into the second waterproof plug fitting portion 54, the second waterproof plug 40 is formed to come into contact with the inside of the second waterproof plug fitting portion 54 in an elastically deformed state to enhance the adhesion.

When the second waterproof plug 40 is pressed and crushed in this axial direction, the second waterproof plug 40 bulges outward and bulges inward (in other words, bulges in the radial direction of the second waterproof plug 40). It is formed as a member that can be elastically deformed.
When the second waterproof plug 40 is pressed and crushed in the axial direction, the second waterproof plug 40 bulges outward and elastically deforms so as to bulge inward. In FIG. 8, it is in close contact with the inner surface of the second waterproof plug fitting portion 54, and in close contact with the outer surface of the coating of the electric wire 39 inside the second waterproof plug 40. As described above, the second waterproof plug 40 shown in FIG. 8 is in close contact with the inner surface of the outer second waterproof plug fitting portion 54 and is also in close contact with the outer surface of the coating of the electric wire 39 inside the second waterproof plug 40. Therefore, the waterproofness of the connector is maintained.

Next, the second terminal 41 will be described.
The second terminal 41 is not particularly limited, but is assumed to be a male terminal in this embodiment.
As shown in FIG. 6, the second terminal 41 is formed in a rectangular tube shape on the distal end side, and has a second terminal contact portion 58 having a plurality of contacts in contact with the first terminal contact portion 33 of the first terminal 8. And a second wire connecting portion 59 to which the terminal of the electric wire 39 is connected, and a second shell 60 provided so as to cover the second terminal contact portion 58 and the second wire connecting portion 59. Yes.

  The second shell 60 is formed in a predetermined shape by sheet metal processing a conductive metal plate. As shown in FIG. 6A, the second shell 60 includes a second terminal connection tube portion 61 formed in a rectangular tube shape as a portion connected to the first terminal 8, and a second terminal connection tube portion 61. The second electric wire crimping part 62 is provided behind and is configured to crimp the terminal part of the electric wire 39.

Here, the procedure for assembling the second connector 2 and the operation of each part will be described.
First, as illustrated in FIG. 5, the second waterproof plug 40 is attached to the outer periphery of the end of the electric wire 39. Further, the second terminal 41 is connected to the end of the electric wire 39.

  Thereafter, the second terminal 41 is inserted into the second electric wire insertion hole 53 from the rear end side of the second housing 38 and is accommodated in the second terminal accommodating chamber 52 as shown in FIG. When the second terminal 41 is accommodated in the second terminal accommodating chamber 52, the distal end side of the second terminal 41 is exposed to the second connector accommodating chamber 48.

  Then, the second waterproof plug 40 is fitted into the second waterproof plug fitting portion 54 in conjunction with the insertion of the second terminal 41 into the second terminal accommodating chamber 52. Then, the tip surface of the second waterproof plug 40 comes into contact with the second waterproof plug contact portion 55 of the second waterproof plug fitting portion 54. As a result, the second waterproof plug 40 is disposed at a predetermined position in the second waterproof plug fitting portion 54. Further, the second terminal 41 is arranged at a predetermined position in the second terminal accommodating chamber 52.

When the second waterproof plug 40 is fitted into the second waterproof plug fitting portion 54, the second waterproof plug 40 is in close contact with the inner surface of the second waterproof plug fitting portion 54 with the outer surface elastically deformed. Thereby, the clearance gap between the electric wire 39 and the inner surface of the 2nd waterproof plug fitting part 54 is filled, and the water immersion to the 2nd terminal storage chamber 52 is prevented.
Thus, the assembly work of the second connector 2 is completed.

Next, a procedure for fitting the first connector 1 and the second connector 2 and the operation of each part will be described.
First, the second connector 2 shown in FIG. 7 is inserted into the connector insertion hole 15 of the first connector 1 shown in FIG. 3 with the second hood portion 42 as the tip. Then, the tip of the second terminal 41 exposed in the second connector housing chamber 48 of the second housing 38 is guided to the terminal guide hole 30 of the spacer 5 and inserted into the first shell 36 of the first terminal 8. .

When the second connector 2 is inserted into the first connector housing chamber 17 as it is, the spacer abutting portion 51 of the second housing 38 shown in FIG. 8 becomes the tip wall of the spacer 5 shown in FIG. 26 abuts on the outer surface.
The spacer 5 with which the spacer contact portion 51 is in contact is pressed in the fitting direction of the second connector 2 (the direction indicated by the arrow D shown in FIG. 11) in conjunction with the insertion of the second connector 2.
Then, the seal member 4 that is in contact with the seal member pressing portion 29 of the spacer 5 is pressed in the fitting direction of the second connector 2. As shown in FIGS. 10 and 11, the seal member 4 mounted on the seal member mounting portion 24 is sandwiched between the rising portion of the seal member mounting portion 24 and the seal member pressing portion 29 of the spacer 5. In this state, the second connector 2 is crushed in the fitting direction.

As shown in FIG. 11, the seal member 4 crushed in the fitting direction of the second connector 2 bulges outward (in the direction indicated by the arrow E shown in FIG. 11) and inward ( It is elastically deformed so as to swell (in other words, so as to swell in the radial direction of the seal member 4) in the direction opposite to the direction indicated by the arrow E shown in FIG.
Here, as will be described later, formed on the rising portion of the seal member mounting portion 24 and the cylindrical portion 27 of the spacer 5 when the tip wall 28 of the spacer 5 is brought into contact with the tip of the first terminal accommodating portion 10. The interval between the seal member pressing portion 29 is smaller than the width of the seal member 4 in the axial direction. For this reason, the seal member 4 is easily crushed by the spacer 5 in the fitting direction of the second connector 2. For this reason, the seal member 4 is easily elastically deformed so as to bulge inwardly and outwardly.
Thereby, the outer peripheral surface of the seal member 4 is elastically deformed on the inner surface of the second hood portion 42 of the second housing 38 inserted into the first housing 3 so as to cover the outer periphery of the first terminal accommodating portion 10. In close contact. Further, the inner peripheral surface of the seal member 4 is in close contact with the outer surface of the first terminal accommodating portion 10 of the first housing 3.
Further, the thickness of the seal member 4 in the circumferential direction is larger than the height of the rising portion of the seal member mounting portion 24 and the thickness of the cylindrical portion 27 of the spacer 5 as shown in FIG. ing. For this reason, when the seal member 4 is crushed and elastically deformed so as to bulge inward and outward, the outer peripheral surface of the seal member 4 reliably adheres to the inner surface of the second hood portion 42 of the second housing 38, and The inner peripheral surface of the seal member 4 is in close contact with the outer surface of the first terminal accommodating portion 10 of the first housing 3.

When the second connector 2 is inserted in the fitting direction, the seal member 4 is further crushed in the fitting direction of the second connector 2. Then, as shown in FIGS. 10 and 11, the inner surface of the tip wall 28 of the spacer 5 comes into contact with the tip of the first terminal accommodating portion 10. At this time, as shown in FIG. 10, the engagement arm 16 of the first housing 3 and the engagement protrusion 50 of the second housing 38 are engaged, and the first connector 1 and the second connector 2 are fitted. State is maintained.
Here, when the leading end wall 28 of the spacer 5 is brought into contact with the leading end of the first terminal accommodating portion 10, the rising portion of the sealing member mounting portion 24 and the sealing member pressing portion formed on the cylindrical portion 27 of the spacer 5. The space | interval between 29 is smaller than the axial width of the seal member 4. For this reason, after the fitting of the first connector 1 and the second connector 2, the seal member 4 is held in an elastically deformed state so as to bulge outward and inward.
Accordingly, the outer peripheral surface of the seal member 4 is in close contact with the inner surface of the second housing 38 and the inner peripheral surface of the seal member 4 is maintained in close contact with the outer surface of the first terminal accommodating portion 10 of the first housing 3. Can do.
Thus, the operation for fitting the first connector 1 and the second connector 2 is completed.

As described above with reference to FIGS. 1 to 11, according to the present invention, when the seal member 5 is pressed by the spacer (first pressing member) 5, the seal member 5 is elastically deformed to cause the first housing. Since the clearance (clearance) between 3 and the spacer 5 can be filled, the inside of the housing can be reliably sealed without providing a large-sized seal member in the housing in the prior art. Since it is not necessary to provide a large-sized seal member in the housing, the insertion force for inserting the second connector 2 into the first housing 3 does not increase when the second connector 2 is fitted.
Therefore, it is possible to improve the waterproof performance of the connector while improving the workability in the connector fitting operation.

Further, according to the present invention, when the second connector 2 is fitted into the first housing 3, the spacer 5 is moved in the fitting direction of the second connector 2 by the fitting of the second connector 2, and the sealing member 4. By pressing, the seal member 4 can be elastically deformed so as to bulge in the radial direction, and the gap (clearance) between the second housing 38 and the spacer 5 can be filled.
Therefore, there is an effect that the waterproof performance of the connector can be further improved while improving the workability in the connector fitting work.

Furthermore, according to the present invention, when the seal member 4 is crushed in the fitting direction of the second connector 2, the seal member 4 is elastically deformed so as to swell larger in the radial direction. It is possible to reliably fill the clearance.
Accordingly, the waterproof performance of the connector can be further improved.

The connector according to the present invention may use Example 2 below in addition to Example 1.
Hereinafter, Example 2 will be described with reference to FIGS. 12 and 13.

The connector 70 according to the present embodiment has the same configuration and structure as the second connector 2 (see FIG. 5) described in the first embodiment except for the cap 71 (second pressing member) illustrated in FIGS. 12 and 13. I have it.
Therefore, in the present embodiment, the configuration and structure of the cap 71 will be described below, and the configuration and structure of the connector 70 other than the cap 71 will be denoted by the same reference numerals as those of the second connector 2 of the first embodiment. Is omitted.

The cap 71 corresponds to a “second pressing member” in the claims.
As shown in FIGS. 12 and 13, the cap 71 is formed in a rectangular shape and has a substantially U-shaped cross section. The cap 71 includes a cylindrical part 72 and a pressing wall 73.
The cylindrical portion 72 is formed as a portion that is attached to the outer periphery of the rear end of the housing 38. Although not particularly illustrated, for example, an engagement protrusion formed so as to be engageable with a concave engaged portion formed at a predetermined position on the rear end of the housing 38 is provided on the inner surface of the cylindrical portion 72. .

The above-described method for engaging the housing 38 and the cap 71 is an example.
In addition, although not particularly illustrated, for example, the following configuration may be used.
A portion for mounting the waterproof plug at the rear end of the housing is formed in a cylindrical shape, and a groove is provided in a spiral shape on the outer surface of the cylindrical portion. The cap is formed in a cylindrical shape that can be engaged with the rear end of the housing. And the protrusion which engages with the groove | channel formed in the rear end of the housing is helically formed in the inner surface of the cap.
Such a cap is mounted by screwing onto the cylindrical portion of the housing.

Returning to FIGS. 12 and 13, the description of the cap 71 will be continued.
The pressing wall 73 is formed so as to cover the rear end surface of the second waterproof plug 40. A through hole 74 through which the electric wire 39 is inserted is formed through the central portion of the pressing wall 73.

Here, the procedure for assembling the connector 70 and the operation of each part will be described.
First, the second waterproof plug 40 is attached to the outer periphery of the terminal of the electric wire 39. Further, the second terminal 41 is connected to the end of the electric wire 39.
Then, as shown in FIG. 12, the second terminal 41 is inserted through the second wire insertion hole 53 from the rear end side of the second housing 38 and inserted into the second terminal accommodating chamber 52.

  When the second terminal 41 is inserted into the second housing 38 as it is, the distal end surface of the second waterproof plug 40 comes into contact with the second waterproof plug contact portion 55 of the second waterproof plug fitting portion 54. . As a result, the second waterproof plug 40 is disposed at a predetermined position in the second waterproof plug fitting portion 54.

When the insertion of the second terminal 41 into the second housing 38 is continued, the second waterproof plug 40 that contacts the pressing wall 73 of the cap 71 is interlocked with the insertion of the second terminal 41, and the second terminal 41. Is inserted in the direction (indicated by the arrow F shown in FIG. 12).
Accordingly, the second waterproof plug 40 is crushed by the cap 71 in the insertion direction of the second terminal 41.

The second waterproof plug 40 crushed in the insertion direction of the second terminal 41 (the direction indicated by the arrow F shown in FIG. 12) bulges outward (in the direction indicated by the arrow G shown in FIG. 13). And bulge inward (in a direction opposite to the direction indicated by the arrow G shown in FIG. 13) (in other words, bulge in the radial direction of the second waterproof plug 40). To elastically deform.
Then, the second waterproof plug 40 is elastically deformed so as to bulge outward while the outer peripheral surface is in close contact with the inner surface of the second waterproof plug fitting portion 54 and bulges inward. Thus, the inner peripheral surface is in close contact with the outer surface of the wire 39. Thereby, the clearance gap between the inner surface of the 2nd waterproofing stopper fitting part 54 and the outer peripheral surface of the 2nd waterproofing stopper 40, and the clearance gap between the outer surface of the coating | cover of the electric wire 39, and the inner peripheral surface of the 2nd waterproofing stopper 40 are obtained. Thus, it is more reliably buried and water intrusion into the second terminal accommodating chamber 52 is more reliably prevented.
Thus, the assembly work of the second connector 2 is completed.

  The connector 70 in the present embodiment is configured to include the second waterproof plug 40 as illustrated in FIGS. 12 and 13, but is not limited to this, for example, in other embodiments illustrated in FIGS. 14 and 15. Such a configuration may be provided.

Therefore, hereinafter, the configuration and structure of the second waterproof plug 81 will be described, and the configuration and structure of the connector 80 other than the second waterproof plug 81 will be denoted by the same reference numerals as those of the connector 70 of the second embodiment, and will be described. Omitted.

As shown in FIG. 14, the second waterproof plug 81 has a second waterproof plug fitting portion whose width in the axial direction is the insertion direction of the second terminal 41 (the direction indicated by the arrow H shown in FIG. 14). It is formed larger than the width of 54. Further, the outer diameter of the second waterproof plug 81 is formed larger than the inner diameter of the second waterproof plug fitting portion 54.
As shown in FIG. 15, such a second waterproof plug 81 is fitted in the second waterproof plug fitting portion 54 and pressed in the insertion direction of the second terminal 41 by the cap 71, and is pushed in this insertion direction. It will be crushed. Then, the second waterproof plug 81 bulges outward (in the direction indicated by the arrow J shown in FIG. 15) and inward (the direction opposite to the direction indicated by the arrow J shown in FIG. 15). It is elastically deformed so as to swell (in other words, so as to swell in the radial direction of the second waterproof plug 81).
Here, the axial width of the second waterproof plug 81 is formed larger than the width of the second waterproof plug fitting portion 54 in the insertion direction of the second terminal 41. For this reason, the second waterproof plug 81 is easily crushed by the cap 71 in the insertion direction of the second terminal 41. For this reason, the second waterproof plug 81 is easily elastically deformed so as to bulge inwardly and outwardly.
Thus, the outer peripheral surface of the second waterproof plug 81 is in close contact with the inner surface of the second waterproof plug fitting portion 54 in an elastically deformed state, and the inner peripheral surface of the second waterproof plug 81 is coated on the outer surface of the covering of the electric wire 39. Is in close contact.
The outer diameter of the second waterproof plug 81 is formed larger than the inner diameter of the second waterproof plug fitting portion 54. For this reason, when the cap 71 is crushed and elastically deformed so as to bulge inwardly and outwardly, the outer peripheral surface of the second waterproof plug 81 is in close contact with the inner surface of the second waterproof plug fitting portion 54, and the second 2 The inner peripheral surface of the waterproof plug 81 is in close contact with the outer surface of the coating of the wire 39.
Thereby, the clearance gap between the inner surface of the 2nd waterproof plug fitting part 54 and the outer peripheral surface of the 2nd waterproof plug 81, and the clearance gap between the outer surface of the coating | cover of the electric wire 39, and the internal peripheral surface of the 2nd waterproof plug 31 are obtained. Thus, it is more reliably buried and water intrusion into the second terminal accommodating chamber 52 is more reliably prevented.

As described above with reference to FIGS. 12 to 15, according to the present invention, the second waterproof plug 40, 81 is pressed by pressing the second waterproof plug 40, 81 with the cap (second pressing member) 71. 81 can be elastically deformed to fill a gap (clearance) between the second housing 38 and the cap 71, so that the terminal accommodating chamber 43 can be reliably sealed without providing a large waterproof plug in the prior art. Can do. Since it is not necessary to insert a terminal fitted with a large waterproof plug into the housing, the insertion force of the terminal fitted with the waterproof plug does not increase during assembly work of the connector.
Therefore, it is possible to improve the waterproof performance of the connector while improving the workability in the assembly work of the connector.

In addition, according to the present invention, when the terminal 41 is inserted into the second terminal accommodating chamber 52, the cap 71 moves in the insertion direction of the terminal 41 and presses the second waterproof plugs 40, 81, thereby providing the second waterproof. The plugs 40 and 81 can be elastically deformed so as to bulge in the radial direction, and a gap (clearance) between the housing 38 and the cap 71 can be filled.
Therefore, there is an effect that the waterproof performance of the connector can be further improved while improving the workability in the assembly work of the connector.

Furthermore, according to the present invention, when the second waterproof plugs 40, 81 are crushed in the pressing direction, the second waterproof plugs 40, 81 are elastically deformed so as to bulge in a larger radial direction. A gap (clearance) between the housing 38 and the cap 71 can be reliably filled.
Accordingly, the waterproof performance of the connector can be further improved.

  In addition, the present invention can of course be modified in various ways within the scope not changing the gist of the present invention.

In the description of the first embodiment, the connector (first connector 1) according to the present invention is applied to a female connector, and the mating connector (second connector 2) that is a mating partner of the connector according to the present invention is a male connector.
