The present disclosure relates to a connector.
Conventionally, a connector described in Japanese Patent Laid-Open Publication No. 2019-145208 (Patent Document 1 below) is known as a connector for accommodating a terminal-equipped wire in which a terminal is connected to a core wire exposed from an end of a wire. This connector is provided with a terminal including a terminal body and a slide portion, a connector housing including a cavity for accommodating the terminal and a rear holder to be locked to the rear end of the terminal. With the slide portion held at a complete locking position with respect to the terminal body, an upper contact portion of the slide portion comes into contact with an upper connecting piece of the terminal body from above and presses the upper connecting piece downward and a lower contact portion of the slide portion comes into contact with a lower connecting piece of the terminal body from below and presses the lower connecting piece upward. In this way, the core wire is vertically sandwiched by the upper and lower connecting pieces and the wire and the terminal are electrically connected.
The above connector is a non-waterproof connector. If an attempt is made to make this connector waterproof, the above connector housing is first used as an inner housing, an outer housing disposed on an outer peripheral side of the inner housing is provided, and the inner housing is surrounded and accommodated by the outer housing and the rear holder. Moreover, it is thought to mount a one-piece rubber plug into a rear end part of the inner housing, thereby making the wire inserted into a wire insertion hole waterproof, and mount a rubber ring between the rear holder and the outer housing, thereby making the inside of the rear holder and the inside of the outer housing waterproof. As just described, two parts need to be made waterproof, and the number of components increases since the one-piece rubber plug and the rubber ring are necessary.
The present disclosure is directed to a connector with a wire including a core wire, a terminal connected to the core wire, an inner housing including a terminal accommodating portion accommodating the terminal inside, an outer housing including a housing accommodating portion accommodating the inner housing inside, a rear holder for holding the inner housing in a state accommodated in the housing accommodating portion by being assembled with the outer housing, and a one-piece sealing portion mounted in the rear holder, the rear holder including a wire insertion hole, the wire being inserted through the wire insertion hole, and the one-piece sealing portion including an inner sealing portion for sealing the wire inserted through the wire insertion hole and an outer sealing portion for sealing between the rear holder and the outer housing, the inner sealing portion and the outer sealing portion being constituted by one member.
According to the present disclosure, since the inner sealing portion and the outer sealing portion are constituted by one member, the inner housing can be made waterproof without increasing the number of components.
First, embodiments of the present disclosure are listed and described.
(1) The connector of the present disclosure is provided with a wire including a core wire, a terminal connected to the core wire, an inner housing including a terminal accommodating portion accommodating the terminal inside, an outer housing including a housing accommodating portion accommodating the inner housing inside, a rear holder for holding the inner housing in a state accommodated in the housing accommodating portion by being assembled with the outer housing, and a one-piece sealing portion mounted in the rear holder, the rear holder including a wire insertion hole, the wire being inserted through the wire insertion hole, and the one-piece sealing portion including an inner sealing portion for sealing the wire inserted through the wire insertion hole and an outer sealing portion for sealing between the rear holder and the outer housing, the inner sealing portion and the outer sealing portion being constituted by one member.
Since the wire inserted through the wire insertion hole is sealed by the inner sealing portion of the one-piece sealing portion and sealing is provided between the rear holder and the outer housing by the outer sealing portion of the one-piece sealing portion, the inner housing can be made waterproof. At that time, since the inner sealing portion and the outer sealing portion are constituted by one member, the number of components can be reduced.
(2) Preferably, the one-piece sealing portion and the rear holder are constituted by one member.
Since the one-piece sealing portion needs not be mounted in the rear holder, the number of mounting steps can be reduced. For example, the one-piece sealing portion and the rear holder may be constituted by one member by forming the one-piece sealing portion in the rear holder by two-color molding.
(3) Preferably, the outer housing includes a seal accommodating portion for accommodating the outer sealing portion in a sealing state inside, and inside of the housing accommodating portion and that of the seal accommodating portion communicate.
Since the inside of the housing accommodating portion and that of the seal accommodating portion communicate, the housing accommodating portion and the seal accommodating portion are easily integrally molded.
(4) Preferably, the rear holder includes a holder receptacle to be externally fit to a rear part of the inner housing and a seal attaching portion disposed behind the holder receptacle, the one-piece sealing portion being attached to the seal attaching portion.
The inner housing can be made waterproof by the one-piece sealing portion attached to the seal attaching portion with the holder receptacle fit to the rear part of the inner housing.
(5) Preferably, the seal attaching portion is provided continuously behind the holder receptacle, the housing accommodating portion includes a rear housing accommodating portion for accommodating the holder receptacle, and the outer housing includes a rear receptacle composed of the rear housing accommodating portion and the seal accommodating portion.
Since the rear housing accommodating portion and the seal accommodating portion are constituted as the rear receptacle, the configuration of the outer housing can be simplified.
(6) Preferably, the rear holder includes a protection wall to be fit to an outer peripheral side of the rear receptacle, and the protection wall includes a through hole for exposing a part of the outer sealing portion to outside before the protection wall is fit to the rear receptacle.
For example, when the one-piece sealing portion is attached to the seal attaching portion by two-color molding, liquid rubber serving as a raw material of the one-piece sealing portion may be injected to the seal attaching portion using the through hole.
(7) Preferably, the rear receptacle includes a lock protrusion for holding the rear holder in a state mounted on the rear receptacle by being locked to an inner wall of the through hole.
The rear holder can be held in the state mounted on the rear receptacle by locking the lock protrusion to the inner wall of the through hole.
(8) Preferably, the outer housing includes a front receptacle open forward, and the front receptacle extends forward to a front end of the housing accommodating portion after extending radially outward from a front end of the rear receptacle.
For example, when a mating housing and the outer housing are connected, the mating housing may be fit to an inner peripheral side of the front receptacle.
A specific example of a connector 10 of the present disclosure is described below with reference to the drawings. Note that the present disclosure is not limited to these illustrations, but is represented by claims and intended to include all changes in the scope of claims and in the meaning and scope of equivalents.
As shown in
The wire W is provided with a core wire W1 and an insulation coating W2 made of insulating synthetic resin and surrounding the outer peripheral surface of the core wire W1. The insulation coating W2 is stripped in an end part of the wire W to expose the core wire W1. The core wire W1 is a so-called single core wire constituted by one metal wire. Note that the core wire W1 may be a stranded wire formed by twisting a plurality of metal thin wires. An arbitrary metal such as copper, copper alloy, aluminum or aluminum alloy can be appropriately selected as a metal for constituting the core wire W1 if necessary. The core wire W1 of this embodiment is made of copper or copper alloy.
The terminal 50 is a female terminal and provided with a terminal body 51 made of metal and a slide portion 52 relatively slidable with respect to the terminal body 51. The terminal body 51 is formed into a predetermined shape by a known method such as press-working, cutting or casting. An arbitrary metal such as copper, copper alloy, aluminum, aluminum alloy or stainless steel can be appropriately selected as a metal for constituting the terminal body 51 if necessary. The terminal body 51 of this embodiment is made of copper or copper alloy. A plating layer may be formed on the surface of the terminal body 51. An arbitrary metal such as tin, nickel or silver can be appropriately selected as a metal for constituting the plating layer if necessary. Tin plating is applied to the terminal body 51 of this embodiment.
As shown in
A resiliently deformable resilient contact piece 51E is disposed on a side wall of the connecting tube portion 51A. The male terminal inserted into the connecting tube portion 51A contacts the resilient contact piece 51E. Further, a locking lance 53 made of metal and formed by cutting and raising a part of the connecting tube portion 51A is provided on a front end part of the upper wall of the connecting tube portion 51A.
The upper connecting piece 51C is formed to be resiliently deformable in the vertical direction with a rear end part of the upper wall of the base portion 51B as a fulcrum. The lower connecting piece 51D is formed to be resiliently deformable in the vertical direction with a rear end part of the lower wall of the base portion 51B as a fulcrum. The upper and lower connecting pieces 51C, 51D are formed to have substantially the same length in the front-rear direction.
The terminal body 51 is further provided with a terminal window portion 51F open upward at a position behind the connecting tube portion 51A and in front of the base portion 51B. A front end part of the core wire W1 can be detected through the terminal window portion 51F with the core wire W1 disposed in a space between the upper and lower connecting pieces 51C, 51D. Being detectable means being visually confirmable by a worker from outside, means being detectable by a camera (not shown) from outside and also means the electrical detection of the front end part of the core wire W1 by inserting a probe (not shown) from outside.
The slide portion 52 is in the form of a rectangular tube extending in the front-rear direction. The slide portion 52 is formed by a known method such as cutting, casting or press-working if necessary. An arbitrary metal such as copper, copper alloy, aluminum, aluminum alloy or stainless steel can be appropriately selected as a metal for constituting the slide portion 52 if necessary. The slide portion 52 of this embodiment is made of copper or copper alloy. A plating layer may be formed on the surface of the slide portion 52. An arbitrary metal such as tin, nickel or silver can be appropriately selected as a metal for constituting the plating layer if necessary. Tin plating is applied to the slide portion 52 of this embodiment.
The slide portion 52 is so formed to have a cross-sectional shape, which is the same as or somewhat larger than that of a region of the terminal body 51 where the upper and lower connecting pieces 51C, 51D are provided. In this way, the slide portion 52 is externally fittable to the region of the terminal body 51 where the upper and lower connecting pieces 51C, 51D are provided.
An upper contact portion 52A projecting downward is provided on the lower surface of the upper wall of the slide portion 52. A lower contact portion 52B projecting upward is provided on the upper surface of the lower wall of the slide portion 52.
The slide portion 52 is slidable between a temporary locking position (not shown) and a complete locking position (position of the slide portion 52 in
With the slide portion 52 held at the complete locking position with respect to the terminal body 51, the upper contact portion 52A presses the upper connecting piece 51C from above, whereby the upper connecting piece 51C is resiliently deformed downward. Further, the lower contact portion 52A presses the lower connecting piece 51D from below, whereby the lower connecting piece 51D is resiliently deformed upward. In this way, in a state where the core wire W1 is disposed to extend in the front-rear direction in the space between the upper and lower connecting pieces 51C, 51D and the slide portion 52 is held at the complete locking position with respect to the terminal body 51, the core wire W1 is sandwiched in the vertical direction by the resiliently deformed upper and lower connecting pieces 51C, 51D. That is, the upper connecting piece 51C contacts the core wire W1 pressed downward by the upper contact portion 52A from above and the lower connecting piece 51D contacts the core wire W1 pressed upward by the lower contact portion 52B from below.
A front part of the upper connecting piece 51C projects downward, a rear part of the lower connecting piece 51D projects upward, and these projecting parts are shifted in the front-rear direction. Thus, the core wire W1 is held in a state bent in the vertical direction. In this way, the core wire W1 and the terminal 50 are electrically connected, and the terminal 50 is firmly held retained against rearward pulling of the wire W.
As shown in
The unillustrated male terminal is insertable into the cavity 21A from front. As shown in
With the terminal 50 accommodated in the cavity 21A, a connector window portion 21B is formed at a position of the terminal accommodating portion 21 corresponding to the terminal window portion 51F of the terminal 50. The terminal window portion 51F communicates with outside through this connector window portion 21B. The terminal window portion 51F of the terminal 50 is detectable through the connector window portion 21B. In this way, the front end part of the core wire W1 is detectable from outside through the connector window portion 21B and the terminal window portion 51F.
As shown in
Temporary locking portions 24 projecting outward are provided at positions near rear end parts of both left and right side walls of the inner housing 20, and complete locking portions 25 are provided at positions forward of the temporary locking portions 24.

The one-piece sealing portion 70 is made of rubber and includes, as shown in
The inner sealing portion 71 seals the wires W inserted through the wire insertion holes 65. As shown in
The outer housing 30 is made of insulating synthetic resin and, as shown in
The inside of the housing accommodating portion 31 and that of the seal accommodating portion 32 communicate. A dimension in the front-rear direction of the housing accommodating portion 31 is larger than that of the seal accommodating portion 32 and about three times as large as that of the seal accommodating portion 32. A vertical dimension of the seal accommodating portion 32 is larger than that of the housing accommodating portion 31 as shown in
The outer sealing portion 72 of the one-piece sealing portion 70 is accommodated in a sealing state inside the seal accommodating portion 32. The housing accommodating portion 31 includes a rear housing accommodating portion 31B for accommodating the holder receptacle 61A. The rear receptacle 34 is composed of the rear housing accommodating portion 31B and the seal accommodating portion 32.
As shown in
The front receptacle 33 extends forward to the front end of the housing accommodating portion 31 after extending radially outward from the front end of the rear receptacle 34. The sealing ring 40 is mounted on the outer peripheral surface of the housing accommodating portion 31. A mating receptacle (not shown) of a mating housing is insertable into between the outer peripheral surface of the housing accommodating portion 31 and the inner peripheral surface of the front receptacle 33, and sealing is provided between the mating housing and the outer housing 30 by sandwiching the sealing ring 40 between the inner peripheral surface of the mating receptacle and the outer peripheral surface of the housing accommodating portion 31.
Next, an example of an assembling process of the connector 10 of this embodiment is described. The assembling process of the connector 10 is not limited to the one described below.
By a known method, the terminal bodies 51 and the slide portions 52 are formed. The slide portion 52 is assembled with the terminal body 51 from behind and the slide portion 52 is held at the temporary locking position. In this way, the terminal 50 is obtained.
By injection-molding the synthetic resin, the inner housing 20, the outer housing 30 and the rear holder 60 are formed. The terminals 50 are inserted into the cavities 21A of the inner housing 20 from behind. Liquid rubber serving as a raw material of the one-piece sealing portion 70 is injected into the rear holder 60, thereby integrally forming the rear holder 60 and the one-piece sealing portion 70 by two-color molding. In this way, the inner sealing portion 71 and the outer sealing portion 72 are constituted by one member. This leads to a reduction in the number of components and a reduction in the number of operation steps since a mounting step of the one-piece sealing portion 70 is eliminated.
The rear holder 60 is assembled with the rear end part of the inner housing 20 from behind. Then, front end parts of the lock receiving portions 64 of the rear holder 60 come into contact with the temporary locking portions 24 of the inner housing 20 from behind, and the lock receiving portions 64 are expanded and deformed. If the rear holder 60 is pushed further forward, the lock receiving portions 64 are restored and the lock receiving portions 64 are resiliently locked to the temporary locking portions 24 of the inner housing 20. In this way, the rear holder 60 is held at the temporary locking position with respect to the inner housing 20. In this state, the holder receptacle 61A of the rear holder 60 is disposed at a position separated rearward from the rear end of the inner housing 20.
The wire W is inserted through the wire insertion hole 65 of the rear holder 60 from behind, and the insulation coating W2 is stripped in an end part of the wire W, whereby the core wire W1 of a predetermined length is exposed.
If the wire W is pushed further forward, the front end part of the core wire W1 is introduced into the slide portion 52 through a rear end part of the slide portion 52. If the wire W is pushed further forward, the front end part of the core wire W1 enters the terminal body 51 and reaches the space between the upper and lower connecting pieces 51C, 51D.
By detecting the front end part of the core wire W1 in the terminal window portion 51F visible through the connector window portion 21B visually or by a probe or the like, it can be confirmed that the core wire W1 has reached a predetermined position. In a state where the slide portion 52 is held at the temporary locking position with respect to the terminal body 51 and the rear holder 60 is held at the temporary locking position with respect to the inner housing 20, the interval between the upper and lower connecting pieces 51C, 51D is set to be larger than the outer diameter of the core wire W1. Thus, when the core wire W1 is inserted into the inner housing 20, the core wire W1 does not receive a large friction force from the upper and lower connecting pieces 51C, 51D. Thus, an insertion force in inserting the wire W into the inner housing 20 can be reduced.
Subsequently, if the slide portion 52 is slid forward using a jig (not shown), the slide portion 52 is held at the complete locking position with respect to the terminal body 51. With the slide portion 52 held at the complete locking position with respect to the terminal body 51, the upper contact portion 52A of the slide portion 52 comes into contact with the upper connecting piece 51C of the terminal body 51 from above and presses the upper connecting piece 51C downward. Further, the lower contact portion 52B of the slide portion 52 comes into contact with the lower connecting piece 51D of the terminal body 51 from below and presses the lower connecting piece 51D upward. In this way, the core wire W1 is vertically sandwiched by the upper and lower connecting pieces 51C, 51D.
Subsequently, the rear holder 60 is pushed further forward with respect to the inner housing 20. Then, the front end parts of the lock receiving portions 64 of the rear holder 60 ride on the complete locking portions 25 to be expanded and deformed. If the rear holder 60 is pushed further forward, the lock receiving portions 64 of the rear holder 60 are restored and resiliently locked to the complete locking portions 25 of the inner housing 20. In this way, the rear holder 60 is held at the complete locking position with respect to the inner housing 20. In this state, the holder receptacle 61A of the rear holder 60 is externally fit to the rear part of the inner housing 20 and the inner housing 20 and the rear holder 60 are integrally configured.
Subsequently, the rear holder 60 is mounted on the outer housing 30 from behind, whereby the inner housing 20 is accommodated into the housing accommodating portion 31. The protection wall 63 of the rear holder 60 is expanded and deformed and rides on the lock protrusions 34A of the outer housing 30. If the rear holder 60 is pushed further forward, the protection wall 63 is restored and the lock protrusions 34 are resiliently locked to the inner walls of the through holes 63A. In this way, the rear holder 60 is held in a state mounted on the outer housing 30. In this state, the outer sealing portion 72 of the one-piece sealing portion 70 is accommodated inside the seal accommodating portion 32 and the outer peripheral lips 72A are held in close contact with the inner peripheral surface of the seal accommodating portion 32. Further, the steps 61D of the holder receptacle 61A are locked to the rear end parts 52C of the slide portions 52 from behind, whereby the terminals 50 are held while being prevented from coming out rearward. Further, the inner housing 20 is made waterproof by the one-piece sealing portion 70.
The connector 10 of the present disclosure is provided with the wires W including the core wires W1, the terminals 50 connected to the core wires W1, the inner housing 20 including the terminal accommodating portion 21 accommodating the terminals 50 inside, the outer housing 30 including the housing accommodating portion 31 accommodating the inner housing 20 inside, the rear holder 60 for holding the inner housing 20 in the state accommodated in the housing accommodating portion 31 by being assembled with the outer housing 30, and the one-piece sealing portion 70 mounted in the rear holder 60. The rear holder 60 includes the wire insertion holes 65, through which the wires W are inserted. The one-piece sealing portion 70 includes the inner sealing portion 71 for sealing the wires W inserted through the wire insertion holes 65 and the outer sealing portion 72 for sealing between the rear holder 60 and the outer housing 30. The inner sealing portion 71 and the outer sealing portion 72 are constituted by one member.
Since the wires W inserted through the wire insertion holes 65 are sealed by the inner sealing portion 71 of the one-piece sealing portion 70 and sealing is provided between the rear holder 60 and the outer housing 30 by the outer sealing portion 72 of the one-piece sealing portion 70, the inner housing 20 can be made waterproof. At that time, since the inner sealing portion 71 and the outer sealing portion 72 are constituted by one member, the number of components can be reduced.
Preferably, the one-piece sealing portion 70 and the rear holder 60 are constituted by one member.
Since the one-piece sealing portion 70 needs not be mounted into the rear holder 60, the number of mounting steps can be reduced. For example, the one-piece sealing portion 70 and the rear holder 60 may be constituted into one member by two-color molding.
Preferably, the outer housing 30 includes the seal accommodating portion 32 for accommodating the outer sealing portion 72 in the sealing state inside, and the inside of the housing accommodating portion 31 and that of the seal accommodating portion 32 communicate.
Since the inside of the housing accommodating portion 31 and that of the seal accommodating portion 32 communicate, the housing accommodating portion 31 and the seal accommodating portion 32 are easily integrally molded.
Preferably, the rear holder 60 includes the holder receptacle 61A to be externally fit to the rear part of the inner housing 20 and the seal attaching portion 61B disposed behind the holder receptacle 61A and having the one-piece sealing portion 70 attached thereto.
With the holder receptacle 61A fit to the rear part of the inner housing 20, the inner housing 20 can be made waterproof by the one-piece sealing portion 70 attached to the seal attaching portion 61B.
Preferably, the seal attaching portion 61B is provided continuously behind the holder receptacle 61A, the housing accommodating portion 31 includes the rear housing accommodating portion 31B for accommodating the holder receptacle 61A, and the outer housing 30 includes the rear receptacle 34 constituted by the rear housing accommodating portion 31B and the seal accommodating portion 32.
Since the rear housing accommodating portion 31B and the seal accommodating portion 32 are constituted as the rear receptacle 34, the configuration of the outer housing 30 can be simplified.
Preferably, the rear holder 60 includes the protection wall 63 to be fit to the outer peripheral side of the rear receptacle 34, and the protection wall 63 includes the through holes 63A for exposing parts of the outer sealing portion 72 to outside before the protection wall 63 is fit to the rear receptacle 34.
For example, when the one-piece sealing portion 70 is formed on the seal attaching portion 61B by two-color molding, the liquid rubber serving as the raw material of the one-piece sealing portion 70 may be injected to the seal attaching portion 61B using the through holes 63A.
Preferably, the rear receptacle 34 includes the lock protrusions 34A for holding the rear holder 60 in the state mounted on the rear receptacle 34 by being locked to the inner walls of the through holes 63A.
By locking the lock protrusions 34A to the inner walls of the through holes 63A, the rear holder 60 can be held in the state mounted on the rear receptacle 34.
Preferably, the outer housing 30 includes the front receptacle 33 open forward, and the front receptacle 33 extends forward to the front end of the housing accommodating portion 31 after extending radially outward from the front end of the rear receptacle 34.
For example, when the mating housing and the outer housing 30 are connected, the mating housing may be fit to an inner peripheral side of the front receptacle 33.
(1) Although the one-piece sealing portion 70 and the rear holder 60 are constituted by one member in the above embodiment, the one-piece sealing portion 70 and the rear holder 60 may be separately formed and the one-piece sealing portion 70 may be assembled with the rear holder 60.
(2) Although the inside of the housing accommodating portion 31 and that of the seal accommodating portion 32 communicate via the inside of the rear housing accommodating portion 31B in the above embodiment, the inside of the housing accommodating portion 31 and that of the seal accommodating portion 32 may directly communicate.
(3) Although the rear holder 60 includes the holder receptacle 61A in the above embodiment, a rear holder may include no holder receptacle. In that case, rearward movements of the terminals 50 may be suppressed by the front end of the seal attaching portion 61B.
(4) Although the seal attaching portion 61B is composed of the pair of upper and lower attachment walls 61E in the above embodiment, a pair of attachment walls may be provided on left and right sides.
(5) Although the rear receptacle 34 is composed of the rear housing accommodating portion 31B and the seal accommodating portion 32 in the above embodiment, a rear receptacle may be composed only of a seal accommodating portion.
(6) Although the protection wall 63 is externally fit to both the rear housing accommodating portion 31B and the seal accommodating portion 32 in the above embodiment, a protection wall needs only to be provided at least on the outer peripheral side of the one-piece sealing portion 70 and may be externally fit to only the seal accommodating portion 32.
(7) Although the pair of left and right through holes 63A are provided in both side surfaces of the protection wall 63 in the above embodiment, a pair of upper and lower through holes may be provided in both upper and lower surfaces of a protection wall.
(8) Although the lock protrusions 34A are provided on the surface of the rear receptacle 34 in the above embodiment, lock protrusions may be provided on tip parts of releasable lock arms and the lock protrusions may be fit into the through holes 63A from outside.
