Description

Connector with a plurality of connectors

Technical Field

The present disclosure relates to connectors.

Background

The connector disclosed in patent document 1 includes a female housing and a male housing that can be fitted to and separated from each other. The male housing has a cover portion. A movable plate movable between an initial position and a fitting position is assembled in the cover portion. The movable plate functions as a protruding piece for protecting the male terminal part in the initial position.

The female housing has a pair of cavity towers in the width direction. Each cavity tower has a cavity for receiving a female terminal fitting. An entrance space is formed between the paired cavity towers in the width direction. The movable plate is provided with an elastic clamping piece protruding to the entering space. The elastic locking piece is locked at the male shell at the initial position and limits the movable plate to move towards the embedded position. The inner side surface (side surface facing the entrance space) facing each other of the cavity towers is formed with a releasing portion for releasing the locking state of the elastic locking piece and the male housing, and for releasing the locking state of the elastic locking piece and the male housing. The female housing is disengaged from the male housing in a state where the releasing portion has engaged the elastic engagement piece. Thus, the movable plate can return to the initial position.

Patent document 2 discloses a movable plate having a rib capable of entering a flexing space of a lance portion. The flexing action of the lance is restricted by the rib, so that the state that the sub-connector is locked by the lance is maintained. Patent document 3 discloses a movable plate having a function of a front end portion holder.

In patent documents 1 to 3, since the movable plate has a plurality of functions, the structure of the connector can be simplified as a whole, contributing to downsizing of the connector.

Detailed Description

[ Description of embodiments of the present disclosure ]

First, embodiments of the present disclosure will be described.

The connector of the present disclosure is provided with a connector,

(1) The connector 1 includes a 2 nd connector and a1 st connector which can be fitted to and separated from each other, the 1 st connector includes a cover portion, a movable plate disposed in the cover portion, and a1 st terminal including a front end portion protruding into the cover portion, the 2 nd connector includes a 2 nd housing fitted in the cover portion, and a 2 nd terminal accommodated in the 2 nd housing, the movable plate is disposed so as to be movable between a fitting position located on a rear side with respect to the cover portion and an initial position located away from the rear side to an opening side, the front end portion of the 1 st terminal is protected by the movable plate in the initial position, the movable plate is connected to the 2 nd terminal in the fitting position, the 2 nd housing includes a 2 nd lance portion which can be deformed to prevent the 2 nd terminal from coming out, a flexing space which allows the 2 nd lance portion to flex, and a locking portion which is provided in the flexing space, the movable plate includes a plate main body through which the 1 st terminal penetrates and a locking portion which protrudes from the plate main body, and is disposed so as to be locked in the position when the locking portion is disposed in the fitting position.

The movable plate has a function (protection function) of protecting the front end portion of the 1 st terminal. The protruding portion of the movable plate has a function (pull-back function) of pulling the movable plate back from the fitting position to the initial position and a function (stopper function) of being disposed in the flexing space to suppress the flexing action of the 2 nd lance portion. Therefore, the structure of the movable plate can be simplified and the movable plate can be miniaturized, compared with the case where the functions (the protection function, the pull-back function, and the stopper function) are provided at different positions of the movable plate. In particular, since the protruding portion is disposed in the deflection space of the 2 nd lance portion, the 2 nd housing is not enlarged.

(2) In the connector according to the above (1), it is preferable that the protruding portion has a plate-shaped protruding body having a plate width in a direction intersecting with a flexing direction of the 2 nd lance portion, and the protruding body is formed so as to be deflectable in the plate width direction by interference between the engaged portion and the locking portion.

Since the protruding body is deformed by the interference of the engaged portion and the locking portion in the plate width direction, the locked state of the engaged portion and the locking portion at the fitting position can be well maintained. Further, since the protruding portion is deflected in the plate width direction which is a direction intersecting the deflection direction of the 2 nd lance portion, the protruding portion is less likely to deflect in the deflection direction of the 2 nd lance portion, and the protruding portion can satisfactorily suppress the deflection operation of the 2 nd lance portion.

(3) In the connector according to the above (2), it is preferable that the projecting body has a deflection allowing portion at an intermediate portion in the board width direction, and the engaged portion has a shape projecting from an end surface in the board width direction of the projecting body.

Since the protruding portion can flex in the widthwise direction while securing the widthwise direction, the strength required for suppressing the flexing action of the 2 nd lance portion can be secured.

(4) In the connector according to the above (3), it is preferable that the projecting body has a solid pressing portion for covering the 2 nd lance portion at the fitting position at a position closer to the distal end side than the deflection allowing portion.

Since the solid pressing portion can contact the 2 nd lance portion, the bending operation of the 2 nd lance portion can be reliably suppressed.

(5) The connector according to any one of (1) to (4), preferably, the distal end surface of the protruding portion is an interference surface capable of interfering with the 2 nd lance portion which has been deformed by bending in the bending space.

If the 2 nd terminal is not inserted into the normal position in the 2 nd housing but stays at the half-insertion position, the 2 nd lance portion is deflected in the deflection space by being pushed by the 2 nd terminal staying at the half-insertion position. In contrast, according to the configuration of (5) above, the interference surface of the protruding portion interferes with the 2 nd lance portion which has been deflected in the deflection space, and further fitting of the 2 nd housing is stopped. Therefore, the occurrence of the state in which the 2 nd terminal is fitted into the cover portion while staying at the half insertion position can be avoided.

(1 St housing 15 and 1st terminal 16)

The 1 st housing 15 is made of synthetic resin, and has a square terminal housing portion 35 and a square cylindrical cover portion 36 protruding forward from the terminal housing portion 35, as shown in fig. 5. The cover 36 is larger than the terminal housing 35 by one turn. As shown in fig. 6, the terminal housing portion 35 has a plurality of male 1 st housing chambers 37 and a plurality of male 2 nd housing chambers 38 as cavities penetrating in the front-rear direction. The first housing chamber 37 on the male side is circular, and is arranged in pairs in the width direction at the left and right intermediate portions of the terminal housing portion 35. Each of the male-side 2 nd housing chambers 38 has a rectangular cross section, and a plurality of male-side 2 nd housing chambers 38 are arranged in order along the width direction and the height direction at both the left and right end portions of the terminal housing portion 35. The terminal housing portion 35 has a pair of left and right 1 st lance portions 39 on the upper surface of the inner wall of each male 1 st housing chamber 37.

Like the 2 nd terminal 14, the 1 st terminal 16 has an outer peripheral surface with a circular cross section, and constitutes a so-called coaxial terminal. The 1 st terminal 16 is connected to the end portion of the coaxial wire 40 (see fig. 4). The 1 st terminal 16 and the coaxial wire 40 have shielding layers (not shown) that suppress the influence of noise. The 1 st terminal 16 is inserted into the 1 st housing 37 on the male side from the rear in a state of being connected to the coaxial wire 40, and is locked by the 1 st lance 39, and is held in a state of being unable to come out from the 1 st housing 37 on the male side. The front end portion of the 1 st terminal 16 is arranged to protrude into the cover 36 in a state where the 1 st terminal 16 is locked to the 1 st lance 39.

As shown in fig. 6, the 1 st housing 15 has a pair of left and right holding portions 41 protruding forward (inside the cover 36) at positions above and laterally outward of the 1 st lance portions 39 on the front surface of the terminal housing 35. The holding portion 41 includes a plate-like holding body 42 that faces the plate in the lateral direction, and a forward-movement restricting portion 43 and a backward-movement restricting portion 44 that protrude from the plate surface on the left and right inner sides (the left and right center sides of the 1 st housing 15) of the holding body 42. The backward movement restricting portions 44 are provided in pairs at the upper and lower end portions of the holding portion 41. The forward limiting portions 43 are disposed in front of the backward limiting portions 44 and between the backward limiting portions 44 in the up-down direction. As shown in fig. 9, the movable plate 17 in the initial position is held so as to be sandwiched between the forward limiting portion 43 and the backward limiting portion 44 of each holding portion 41. The advance restriction portion 43 restricts the advance of the flap 17. The backward movement restricting portion 44 restricts the backward movement of the movable plate 17. When the 2 nd connector 11 and the 1 st connector 12 are fitted, the holding portions 41 are inserted into the through holes 31 of the 2 nd housing 13.

As shown in fig. 6, the cover 36 has a locking portion 45 protruding downward (inside the cover 36) from the left and right intermediate portions of the upper wall. The 2 nd housing 13 is fitted into the cover 36. When the 2 nd housing 13 is fitted into the cover 36 at a regular depth, the lock portion 45 is locked to the lock arm 29. The cover 36 has a pair of right and left guide ribs 46 protruding downward (inside the cover 36) at positions on the right and left sides of the upper wall with the lock portion 45 interposed therebetween.

(Movable plate 17)

The movable plate 17 is made of synthetic resin, and has a plate-like plate body 47 that faces the plate in the front-rear direction, as shown in fig. 5. The plate main body 47 is inserted into the cover 36. The outer edge of the plate body 47 has a shape corresponding to the inner surface of the cover 36, and is disposed on the inner surface of the cover 36 in the circumferential direction. As shown in fig. 7, a recess 48 is formed in the left and right intermediate portions of the upper edge of the plate main body 47. The bottom surface of the recess 48 is disposed at a position slightly lower than the left and right end portions of the upper edge of the plate main body 47. In a state where the plate main body 47 is inserted into the cover 36, the concave portions 48 are provided with the guide ribs 46 (see fig. 9).

The plate body 47 has a pair of right and left through holes 49 penetrating the plate thickness direction at positions on the right and left sides across the recess 48. Each through hole 49 has a rectangular shape long in the up-down direction. As shown in fig. 9, the holding portion 41 is inserted into each through hole 49.

As shown in fig. 7, the plate body 47 has a plurality of insertion holes 51, 52 penetrating in the plate thickness direction (front-rear direction). Each of the insertion holes has a circular 1 st insertion hole 51 arranged in pairs in the width direction at the left and right intermediate portions of the plate body 47, and a plurality of rectangular 2 nd insertion holes 52 arranged in alignment in the width direction and the height direction at the left and right end portions of the plate body 47. As shown in fig. 5, the tip end portion of each 1 st terminal 16 is inserted into each 1 st insertion hole 51 in a positioned state (fig. 5 shows only one 1 st terminal 16). The front end portion of each general male terminal is inserted into each 2 nd insertion hole 52 in a positioned state.

As shown in fig. 5 and 7, the movable plate 17 has a pair of right and left protection portions 53 protruding forward from the opening edge portions of the 1 st insertion holes 51 on the front surface of the plate body 47. The protection portions 53 are arranged in a plate shape having a circular arc cross section extending along the left and right sides at the lower portion of the opening edge portion of the 1 st insertion hole 51 so as to cover the distal end portions of the 1 st terminals 16 from the left and right sides.

As shown in fig. 7, the movable plate 17 has a pair of left and right protruding portions 54 protruding forward from the upper edge of the opening of each 1 st insertion hole 51 on the front surface of the plate body 47. The protruding portions 54 are disposed above the protecting portions 53 in the movable plate 17 at positions on the left and right inner sides (left and right center sides of the movable plate 17) of the through holes 49. Each of the protruding portions 54 has a plate shape with the plate surface facing in the up-down direction. As shown in fig. 7 and 8, each of the protruding portions 54 has a protruding body 55 whose outer edge is rectangular in a plan view. The projecting body 55 has a deflection allowing portion 56 extending in the front-rear direction and penetrating in the plate thickness direction (up-down direction) at the left-right intermediate portion. The rear end of the flexure tolerant portion 56 opens at the rear surface of the plate main body 47. The front portion of the protruding body 55 is a solid pressing portion 57 having a constant up-down thickness as a whole. The tip of the deflection allowing portion 56 is closed by the pressing portion 57. The front end surface of the pressing portion 57 constitutes the front end surface of the protruding portion 54 in the protruding direction, and is disposed in front of each of the protection portions 53. The front end surface of the pressing portion 57 is configured as an interference surface 58 along the left-right direction. As will be described later, the interference surface 58 can interfere with the 2 nd lance portion 21 which has been deflected in the deflection space 25 (refer to fig. 10).

As shown in fig. 7 and 8, each protruding portion 54 has a locked portion 59 protruding from the left and right inner end surfaces of the protruding body 55 (the opposing surfaces of the protruding bodies 55 of each protruding portion 54 facing each other). The engaged portion 59 is disposed in the middle of the front and rear of the protruding portion 54, which is a position overlapping the flexure allowing portion 56 in the lateral direction. As shown in fig. 1 and 8, the front surface of each engaged portion 59 is inclined rearward. The rear surfaces of the engaged portions 59 are arranged in the left-right direction. The end surfaces of the engaged portions 59 are arranged to extend in the front-rear direction between the front surface and the rear surface.

< Action of connector 10>

The movable plate 17 is assembled so as to be movable in the front-rear direction with respect to the cover 36 between the initial position and the fitting position. In the fitting position, as shown in fig. 1, the movable plate 17 is positioned on the inner side of the cover 36, and the plate body 47 is disposed in contact with or in proximity to the front surface of the terminal housing 35. In the initial position, as shown in fig. 9, the movable plate 17 is located at a position away from the inner side of the cover 36 to the opening side, and the plate main body 47 is arranged to be separated from the terminal housing 35.

As shown in fig. 9, in the initial position, the holding body 42 of the holding portion 41 is inserted into the through hole 49 of the plate body 47. Here, the forward movement restriction portion 43 is disposed so as to face the front surface of the plate main body 47 in a contact manner. Thereby restricting the movement of the flap 17 to the opening side (front side) of the cover 36. In the initial position, the backward movement restricting portion 44 is disposed so as to face the rear surface of the plate main body 47. Thereby, the movement of the movable plate 17 to the back side (rear side) of the cover 36 is also restricted. As shown in fig. 5, the front end portion of the 1 st terminal 16 penetrates the 1 st insertion hole 51 of the plate body 47, and the front end surface is exposed on the front surface side of the plate body 47.

When the 2 nd connector 11 and the 1 st connector 12 start to be fitted, the protruding portions 54 are fitted into the flexing spaces 25 of the 2 nd housing 13, and the engaged portions 59 of the protruding portions 54 interfere with the engaging portions 26. Thereby, the projection body 55 of each projection 54 is deformed by deflection in the width direction in which the deflection allowing portion 56 is narrowed. As the fitting of the 2 nd connector 11 and the 1 st connector 12 proceeds, the respective locking portions 26 pass over the respective locked portions 59, the respective projecting bodies 55 elastically return, and the respective locking portions 26 are arranged so as to face each other in contact with the rear surface (rear surface when viewed from the 1 st connector 12) of the respective locked portions 59.

During the bending deformation of the protruding bodies 55, the tip ends of the holding portions 41 enter the through holes 31 of the 2 nd housing 13, and the canceling portions 32 interfere with the advance restricting portions 43. Accordingly, the holding body 42 of each holding portion 41 is deformed by bending the front surface of the terminal housing portion 35 to the left and right outside in the through hole 49, and the locking of the plate body 47 by the retraction restricting portion 44 is released. Thereafter, the front surface of the 2 nd housing 13 (the front surface when viewed from the 2 nd connector 11, including the front surface of the wall portion 27) abuts against the front surface of the plate main body 47 (the front surface when viewed from the 1 st connector 12). The respective protruding bodies 55 are elastically restored at the same time as or slightly before the abutment of the 2 nd housing 13 against the plate body 47. Due to the further fitting, the movable plate 17 is pushed by the 2 nd housing 13 to the fitting position and retreats. The holding body 42 of each holding portion 41 is elastically restored during the retraction of the movable plate 17.

As shown in fig. 1, when the movable plate 17 reaches the fitting position, the plate main body 47 is arranged to be sandwiched between the front surface of the terminal housing 35 (front surface when viewed from the 1 st connector 12) and the front surface of the 2 nd housing 13 (front surface when viewed from the 2 nd connector 11). In the fitting position, the lock arm 29 engages the lock portion 45, and the 2 nd connector 11 and the 1 st connector 12 are held in a fitted state. In the fitting position, the distal ends of the 2 nd terminal 14 and the 1 st terminal 16 are fitted and connected to each other.

As shown in fig. 2, in a state where the pressing portion 57 of the protruding portion 54 has entered the flexing space 25, the pressing portion 57 faces the upper surface of the tip end portion (portion in front of the locking projection 24) of the lance body 23 of the 2 nd lance portion 21 so as to be able to contact therewith, and displacement of the 2 nd lance portion 21 to the flexing space 25 is suppressed. Therefore, the locking protrusion 24 of the 2 nd lance 21 is fitted into the locking recess 34, and the 2 nd terminal 14 is held in the locked state.

In contrast, if the 2 nd terminal 14 is not inserted into the 1 st housing chamber 18 on the female side to a normal depth and stays at the half insertion position, the locking projection 24 passes over the outer peripheral surface of the 2 nd terminal, and the lance body 23 of the 2 nd lance 21 protrudes obliquely upward and is disposed in the deflection space 25, as shown in fig. 10. When the fitting of the 2 nd connector 11 and the 1 st connector 12 is started in a state where the 2 nd terminal 14 is stopped at the half-inserted position, the interference surface 58 of the projection 54 abuts against the front end surface of the lance body 23, and the further fitting of the 2 nd connector 11 and the 1 st connector 12 is stopped. Therefore, the state in which the 2 nd terminal 14 is retained in the half-inserted position in the female 1 st housing chamber 18 is not changed, and the 2 nd connector 11 and the 1 st connector 12 can be prevented from being fitted.

Further, if the 2 nd connector 11 is to be fitted in an irregular posture inclined from the regular fitting posture with respect to the 1 st connector 12, the front surface of the 2 nd housing 13 (the front surface when viewed from the 2 nd connector 11) interferes with the interference surface 58 of the protruding portion 54. Further fitting of the 2 nd housing 13 in the irregular posture is stopped by interference of the 2 nd housing 13 with the interference surface 58 of the protruding portion 54. As a result, the occurrence of the situation in which the 2 nd connector 11 and the 1 st connector 12 are fitted tightly can be avoided.

When the 2 nd connector 11 and the 1 st connector 12 in the fitted state are disengaged from each other due to maintenance or the like, the locking of the lock arm 29 and the lock portion 45 is released, and the 2 nd housing 13 is moved in the disengaging direction from the inside of the cover portion 36. From the state shown in fig. 1, as the 2 nd housing 13 moves in the disengaging direction, the locking portions 26 are hooked from behind (rearward when viewed from the 1 st connector 12) and push the locked portions 59, so that the movable plate 17 moves in the disengaging direction together with the 2 nd housing 13.

During the movement of the movable plate 17 to the initial position, the respective retraction restricting portions 44 slide on the inner surfaces of the respective through holes 31, and the holding bodies 42 of the respective holding portions 41 flex laterally outward. When the movable plate 17 reaches the initial position, the holding body 42 of each holding portion 41 is elastically restored, and the plate body 47 is arranged to be sandwiched again between the forward limiting portion 43 and the backward limiting portion 44. Accordingly, the movable plate 17 is configured to be held at the initial position and to be restrained from moving. When the 2 nd housing 13 is moved in the disengaging direction, the one panel main body 47 is locked by the advance restricting portion 43, and the locking portions 26 are released from locking with the locked portions 59 in accordance with the bending deformation of the projecting main body 55 of the projecting portion 54. Therefore, the movable plate 17 can be left at the initial position to disengage the 2 nd housing 13 from the cover 36.

As described above, the movable plate 17 according to embodiment 1 is disposed so as to be movable between the fitting position on the rear side and the initial position on the opening side from the rear side with respect to the cover 36. The front end portion of the 1 st terminal 16 is protected by a movable plate 17 at an initial position, and is connected to the 2 nd terminal 14 at a fitting position, and the 2 nd housing 13 includes a 2 nd lance portion 21 which is elastically deformable and prevents the 2 nd terminal 14 from coming out, a flexing space 25 which allows the 2 nd lance portion 21 to flex, and a locking portion 26 which is provided in the flexing space 25. Further, the movable plate 17 has a plate body 47 through which the 1 st terminal 16 passes and a protruding portion 54 protruding from the plate body 47. The protruding portion 54 has a locked portion 59 that can be locked to the locking portion 26 when the fitting position is disposed in the flexing space 25 and moved from the fitting position to the initial position.

The movable plate 17 has a function (protection function) of protecting the tip end portion of the 1 st terminal 16 in the initial position. The protruding portion 54 of the movable plate 17 has a function (a pull-back function) of pulling the movable plate 17 back from the fitting position to the initial position and a function (a stopper function) of being disposed in the flexing space 25 to restrict the flexing operation of the 2 nd lance portion 21. Therefore, the structure of the movable plate 17 can be simplified, and the locking mechanism of the movable plate 17 can be made smaller than the case where the functions (the protection function, the retracting function, and the locking function) are provided at different positions of the movable plate 17. In particular, since the protruding portion 54 is disposed in the flexing space 25 of the 2 nd lance portion 21, the 2 nd housing 13 is not enlarged. As a result, the connector 10 according to embodiment 1 can set the pull-back structure of the movable plate 17 without increasing the space.

The projection 54 has a plate-like projection body 55 having a plate width in a direction intersecting the flexing direction of the 2 nd lance 21, and the projection body 55 is formed so as to be deflectable in the plate width direction by interference of the engaged portion 59 and the engaging portion 26. Since the protruding portion 54 is deflected in the plate width direction, which is a direction intersecting the deflection direction of the 2 nd lance portion 21, it is possible to form a structure that is less likely to deflect in the deflection direction of the 2 nd lance portion 21, and it is possible to satisfactorily suppress the deflection operation of the 2 nd lance portion 21.

The projecting body 55 has a deflection allowing portion 56 at the left and right intermediate portions, and the engaged portion 59 has a shape projecting from the left and right end surfaces of the projecting body 55. Therefore, since the protruding portion 54 can flex in the widthwise direction while securing the widthwise direction, the strength required for suppressing the flexing operation of the 2 nd lance portion 21 can be secured.

The protruding body 55 has a solid pressing portion 57 for covering the 2 nd lance portion 21 at the fitting position on the tip end side of the deflection allowing portion 56. Since the solid pressing portion 57 can contact the 2 nd lance portion 21, the bending operation of the 2 nd lance portion 21 can be reliably suppressed.

The tip end surface of the protruding portion 54 is an interference surface capable of interfering with the 2 nd lance portion 21 which has been deformed in the deflection space 25. If the 2 nd terminal 14 is left at the half insertion position in the 2 nd housing 13, the 2 nd lance portion 21 is pushed by the 2 nd terminal 14 and is deflected in the deflection space 25, the interference surface of the projection 54 interferes with the 2 nd lance portion 21 deflected in the deflection space 25, and further fitting of the 2 nd housing 13 is stopped. Therefore, the occurrence of the state in which the 2 nd terminal 14 is fitted into the cover portion in the state in which the 2 nd housing 13 is retained at the half insertion position can be avoided.

The above embodiment 1 of the present disclosure is to be considered as illustrative in all respects, and not restrictive.

In embodiment 1, the deflection allowing portion 56 has a shape penetrating the left and right intermediate portions of the protruding body 55 in the plate thickness direction. In contrast, according to another embodiment, the deflection allowable portion may be formed in a shape in which the left and right intermediate portions of the protrusion body are thinner than the left and right end portions and are deflectable.

In embodiment 1 described above, the 1 st terminal 16 is a coaxial terminal having a shield layer. In contrast, according to other embodiments, the 1 st terminal may be a general male terminal without a shield layer.

In embodiment 1 described above, the terminal of the 1 st connector 12 is constituted by the 1 st terminal 16 and the normal male terminal as coaxial terminals, and the terminal of the 2 nd connector 11 is constituted by the 2 nd terminal 14 and the normal female terminal as coaxial terminals. In contrast, according to another embodiment, the 1 st connector terminal may be constituted by only the 1 st terminal, and the 2 nd connector terminal may be constituted by only the 2 nd terminal.

In embodiment 1, the movable plate 17 is provided with two protruding portions 54, and each protruding portion 54 is provided with one engaged portion 59. In contrast, according to another embodiment, one or more than three protruding portions may be provided on the movable plate, and a plurality of engaged portions may be provided for each protruding portion.
