Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector capable of coping with the erroneous insertion of a sub-housing at low cost. <P>SOLUTION: When sub-housings 20, 20a are housed in a housing chamber 11 of a frame 10, not only the regular housing 20 but also the other housing is housed in the housing chamber. When fitted to a mate side male connector M together with the frame 10, and when the inserted connector is the regular sub-housing 20, a discrimination rib 28 of a discrimination part 26 matches with a detection groove 73 of a detection part 70 of the male connector M, and the fitting of both connectors F, M is allowed. When the other connector 20a is erroneously inserted, the discrimination rib 28 of a discrimination part 26 does not match with a detection groove 73, and the fitting of both connectors F, M is restricted by touching the surface of the detection part 70. By this, the erroneous insertion of the sub-housing is prevented. Since the correctness of the sub-housing is determined not between the frame and itself but between the mate connector and itself, the frame can be standardized to a common frame. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a split connector in which a plurality of sub-housings are inserted into a frame.

The split connector includes a frame in which a plurality of storage chambers are arranged side by side, and each sub-housing with terminal fittings is inserted into each of the storage chambers so that each frame is fitted with a mating connector (for example, , See Patent Document 1).
On the other hand, in such a divided connector, for example, when the grade is different even in the same vehicle type, a plurality of types of sub-housings having different numbers of poles and types of terminal fittings are selectively inserted into one accommodation chamber. It may be used like this.

In such a case, it is necessary to detect whether or not the selected sub-housing is properly inserted. In the case of a regular sub-housing, the sub-housing side is usually provided with ribs at different positions on the outer surface on the sub-housing side, while the frame side is provided with a relief groove at the corresponding position of the mouth of the storage chamber. In the case of other sub-housings, the ribs are allowed to move into the escape groove, and in the case of other sub-housings, the ribs abut against the rim of the storage chamber and the insertion is restricted, thereby detecting the correctness of the sub-housing. Are known.
JP-A-6-119955

However, in the above-described method, it is necessary to form a dedicated frame with a different position of the relief groove every time the combination of the sub-housings is different, which leads to high costs including manufacturing costs and management costs. There was a problem.
The present invention has been completed based on the above circumstances, and an object thereof is to make it possible to prevent the erroneous insertion of the sub-housing in the split connector at a low cost.

  As means for achieving the above-mentioned object, the invention of claim 1 is characterized in that a sub-housing with terminal fittings is inserted into each of the housing chambers in a frame provided with a plurality of housing chambers. A split connector adapted to be mated with a mating connector, wherein a plurality of types of sub-housings having different numbers of poles and types of terminal fittings are selectively inserted into at least one housing chamber In the sub-housing to be selectively inserted, different types of identification portions are provided for each type, while in the corresponding storage chamber, all types of sub-housings can be inserted, and on the mating connector side, Detection unit that allows fitting of both connectors without interference with the identification part of one sub-housing, and restricts fitting of both connectors by interfering with the identification part of the other sub-housing. Characterized in place where the structure is provided.

According to a second aspect of the present invention, in the one according to the first aspect, either one of the identification unit and the detection unit is provided with a rib along the fitting direction of both connectors, and the other is the It is characterized in that a groove is provided that allows the rib to slide and allow advancement along the fitting direction.
The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the identification part and the detection part are engageable from the initial state of the fitting operation of both connectors. Have

<Invention of Claim 1>
When the sub-housing is selectively inserted into the housing chamber of the frame, both the regular sub-housing and the other types are once accommodated in the housing chamber. After that, when the frame is mated with the mating connector, if the inserted sub-housing is a genuine one, the mating of both connectors is allowed without the identification portion interfering with the sensing portion of the mating connector. . On the other hand, if it is not a regular sub-housing, the identification part interferes with the detection part and the fitting of both connectors is restricted. This prevents erroneous insertion of the sub-housing.
Since the detection of the correctness of the sub-housing is performed not with the frame but with the mating connector, the frame can be shared with a single frame. However, on the mating connector side, it is necessary to form multiple types with different detection unit shapes and installation positions, but on the mating connector side, if the number of poles and terminal fittings are different, the shape of the connector itself is changed. If it is necessary to change the formation mode of the detection unit at that time, it will not be a new burden. As a result, since the frame can be shared, the cost can be reduced.

<Invention of Claim 2>
When the regular sub-housing is inserted, the two connectors are fitted straightly while the rib is in sliding contact with the mating groove. In other words, the two connectors can be fitted without being twisted, and the terminal metal fitting can be prevented from being bent.
<Invention of Claim 3>
When a sub-housing other than a regular one is inserted, the identification unit interferes with the detection unit at the initial time when both connectors are fitted, and the fitting is restricted. Misinsertion is useful at an early stage of the mating operation. On the other hand, when the regular sub-housing is inserted, the function of preventing twisting is exhibited from the early stage of fitting.

<Embodiment>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In this embodiment, as shown in FIG. 1, the female connector F and the male connector M which are mutually fitted are provided. The female connector F corresponds to the split connector of the present application, and the male connector M corresponds to the mating connector of the present application. The female connector F is fitted with the assisting force of the lever 53.
In the following, the connectors F and M will be described with the fitting surface side as the front.

The female connector F includes a frame 10 made of synthetic resin. As shown in FIGS. 2 to 5, the frame 10 is formed in a horizontally-long block shape as a whole, and two storage chambers 11, 12 are formed in the inside with a partition portion 13 interposed therebetween. Has been. The left side when viewed from the front is a relatively large large storage chamber 11 (hereinafter referred to as a large storage chamber 11), and the right side is a relatively narrow small storage chamber 12 (hereinafter referred to as a small storage chamber 12). Yes.
Front openings 15 are formed on the front surfaces of the storage chambers 11 and 12 so as to pass through the relatively thin front wall 14, and the rear walls of the storage chambers 11 and 12 have a relatively thick rear wall. A rear opening 17 is formed through 16. The rear opening 17 is slightly wider than the front opening 15.

Each of the large storage chamber 11 and the small storage chamber 12 of the frame 10 has a female-side large sub-housing 20 (hereinafter referred to as a large sub-housing 20) and a small sub-housing 30 (hereinafter referred to as a small sub-housing 30). It is inserted from behind and can be accommodated.
As shown in FIG. 6A, the large sub-housing 20 is formed in a relatively wide block shape corresponding to the large accommodating chamber 11, and is, for example, a relatively large female terminal fitting (not shown). In the following, a total of 14 cavities 21 in which large female terminals are accommodated are formed in two upper and lower stages. On the other hand, the small sub-housing 30 is formed in a relatively narrow block shape corresponding to the small accommodating chamber 12, as shown in FIG. A total of 24 cavities 31 in which three small female terminals are accommodated are formed in three upper and lower stages.

  Furthermore, in this embodiment, instead of the large sub-housing 20 (hereinafter referred to as the first large sub-housing 20), the large accommodating chamber 11 of the frame 10 is replaced with another large sub-housing 20a (hereinafter referred to as the second large sub-housing 20a). ) Can be accommodated selectively. As shown in FIG. 6C, the second large sub-housing 20a has the same outer shape as the first large sub-housing 20, but the type and number of female terminal fittings to be mounted are different. A total of 27 cavities 31 in which female terminals are accommodated are formed in three upper and lower stages. Each of the sub-housings 20, 20a and 30 is made of a synthetic resin.

  The left and right side edges of the front surfaces of the large sub-housings 20 and 20a and the small sub-housing 30 are formed with stepped portions 23 and 33 that are recessed rearward by a predetermined dimension, and the lower surface is directed in the front-rear direction toward the left and right ends. Guide ribs 24 and 34 and lock projections 25 and 35 are formed at the center. On the other hand, in both storage chambers 11 and 12 of the frame 10, guide grooves 18 facing in the front-rear direction are formed on the left and right sides of the bottom surface, and a lock arm 19 that can be bent and deformed in the center is formed.

Therefore, the first large sub-housing 20 and the second large sub-housing 20a are inserted from the rear into the large accommodating chamber 11 with the guide ribs 24 along the guide grooves 18 and the lock arms 19 being bent and deformed. The stepped portion 23 of the large storage chamber 11 hits the back side of the left and right mouth edges of the front opening 15 of the large storage chamber 11, so that the front surface is stopped in front with the front opening being flush with the front opening 15. Is prevented from coming off by being elastically locked to the lock arm 19.
The small sub-housing 30 is also inserted into the small accommodating chamber 12 from the rear in the same manner as described above, and is stopped in front with the front face flush with the front opening 15 of the small accommodating chamber 12. To prevent it from coming off.

Identification parts 26, 26a, and 36 are formed on the left and right sides of each of the sub-housings 20, 20a, and 30 to identify the type. Specifically, the identification portions 26, 26 a and 36 are formed at a position slightly inward from the step portions 23 and 33 on the left and right sides of the sub-housings 20, 20 a and 30 and at a central height position.
The identification portions 26, 26 a and 36 are formed by projecting identification ribs 28 and 38 in an outward horizontal posture on the surfaces of the vertically oriented substrates 27 and 37. The discriminating is performed depending on whether the discriminating ribs 28 and 38 are projected from the upper, middle or lower positions.

The identification portion 26 of the first large sub-housing 20 shown in FIG. 6A has a shape in which an identification rib 28 is raised at the center height position of the substrate 27, while the second large sub-housing shown in FIG. The identification part 26 a of the housing 20 a has a shape in which an identification rib 28 is raised at a lower position of the substrate 27. Further, the identification portion 36 of the small sub-housing 30 shown in FIG.
As shown in FIG. 1, the identification portion 36 of the small sub-housing 30 is formed to have a shorter depth than the identification portion 26 (26a) of the large sub-housing 20 (20a) due to the mounting position of the retainer. Yes.

Further, the structure of the frame 10 will be described. As shown in FIGS. 3 and 4, a rear opening 17 of the large storage chamber 11 and a rear opening 17 of the small storage chamber 12 are formed on the rear surface of the frame 10 with the rear wall 16 therebetween. Has been.
Insertion into the left side edge of the rear opening 17 of the large storage chamber 11 as seen from the rear surface is such that the left identification portions 26 and 26a of the large sub-housings 20 and 20a as viewed from the rear surface can be inserted. The hole 41 is formed so as to cut out the rear wall 16. In addition, an insertion hole 41 through which the right identification portion 36 viewed from the back surface formed in the small sub-housing 30 can be inserted in the right side edge viewed from the back surface of the rear opening 17 of the small storage chamber 12. Similarly, it is formed so as to cut out the rear wall 16.
A large side housing 20, a right side edge viewed from the rear side of the rear opening 17 in the large storage chamber 11, and a left side edge viewed from the rear surface in the rear opening 17 of the small storage chamber 12, respectively, An escape groove 43 is formed in the side wall 20 so as to cut out the inner surface of the side wall. The front surfaces of both escape grooves 43 are dead ends.

  On the front surface of the frame 10, an insertion window is inserted through a front wall 14 positioned between the front opening 15 of the large storage chamber 11 and the small storage chamber 12, specifically, a detection unit 70 provided on the male connector M side described later. A hole 45 is formed. This insertion window hole 45 is basically formed in a vertically long rectangle having a height comparable to the height of the front opening 15 of both storage chambers 11 and 12. From the left and right side edges of the insertion window hole 45, a pair of upper and lower protrusions 46 extending rearward are formed so as to face each other, and the rearward extension ends of the protrusions 46 are connected to the rear wall 16. Has been.

The distance between the protrusions 46 paired up and down is formed substantially equal to the height dimension of the substrates 27 and 37 in the identification portions 26, 26 a and 36 provided in the sub-housings 20, 20 a and 30. In addition, a stopper 47 that abuts the substrates 27 and 37 of the identification portions 26, 26 a and 36 is formed at the front end portion of the protrusion 46 that forms a pair in the vertical direction. The opposing surfaces of both stoppers 47 are formed flush with the left and right side edges of the insertion window hole 45.
As described above, when the sub-housings 20, 20a and 30 are inserted into the corresponding storage chambers 11 and 12, the identification portions 26, 26a and 36 on the partitioning portion 13 side have the substrates 27 and 37 protruding vertically. When the sub-housings 20, 20 a, and 30 are stopped in advance through the spaces between the strips 46, the substrates 27 and 37 abut against the stopper 47 in a flush state. Therefore, the identification ribs 28 and 38 in the respective identification portions 26, 26 a and 36 come to positions protruding from the opposing surface of the stopper 47 in the left-right direction.
In other words, the area between the upper and lower ridges 46 on the left and right side edges of the insertion window hole 45 is the identification area 49, and the identification section 26 is located at any of the upper, middle, and lower positions in each identification area 49. , 26a and 36 face the identification ribs 28 and 38.

A lever mounting groove 51 is formed on the upper and lower walls of the frame 10, and a detailed description is omitted, but a lever 53 having a cam groove 54 is rotatably accommodated about a shaft 55. Yes. On the outer peripheral surface of the frame 10, a rib 57 for preventing twisting facing in the front-rear direction and the fitting groove 58 are formed at appropriate positions.
In the following, the first female connector F is inserted into the large storage chamber 11 of the frame 10 and the second female housing is inserted into the large storage chamber 11 with the second large sub housing 20a inserted therein. It is distinguished as a connector Fa.

The male connector M is a PCB connector used by being attached to a printed circuit board, and two types of a first male connector M shown in FIG. 8 and a second male connector Ma shown in FIG. 9 are prepared. . The first male connector M is used corresponding to the first female connector F in which the first large sub-housing 20 is inserted into the large accommodating chamber 11 of the frame 10 described above.
The first male connector M includes a housing 60 made of a synthetic resin, and has a shape in which a hood portion 62 capable of fitting the above-described frame 10 inside is provided on the front surface of a base wall 61. On the inner peripheral surface of the hood portion 62, a fitting groove 63 and a rib 64 are formed, which are aligned with the rib 57 and the fitting groove 58 for preventing the twisting of the frame 10, respectively. Further, follower pins 65 are provided on the upper and lower inner peripheral surfaces of the housing 60 so as to be engaged with the cam grooves 54 of the lever 53 attached to the frame 10.

  L-shaped tab-shaped male terminal fittings 66, 67 are attached to the housing 60 so as to penetrate the base wall 61, and one end of the housing 60 projects into the hood portion 62. The other end protruding to is connected to a conductive path of a printed circuit board (not shown). In the first male connector M, as shown in FIG. 8, a relatively large male terminal fitting 66 (hereinafter referred to as a large male terminal 66) is provided in a relatively wide area on the right side as viewed from the front in the hood portion 62. A relatively small male terminal fitting 67 (hereinafter referred to as a small male terminal 67) is mounted in an array corresponding to the cavity 21 of the first large sub-housing 20 and is relatively narrow on the left side. The housing 30 is mounted in an arrangement corresponding to the cavity 31.

As shown in FIG. 1, a detection unit 70 for detecting erroneous insertion is slightly behind the front edge of the hood unit 62 at a position between the left and right regions in the hood unit 62. It is formed in the shape of a cantilever so as to protrude toward the position where it enters. Specifically, as will be described later, when the male and female connectors are properly fitted, the setting is such that the tip of the detection unit 70 hits the rear wall 16 of the frame 10.
The basic cross-sectional shape of the detection unit 70 is a shape aligned with the insertion window hole 45 provided on the front surface of the frame 10 described above. In particular, the left and right side edges of the wide portion at the center height position are detection areas 72 that face the left and right identification areas 49 of the insertion window hole 45. More specifically, the left and right detection areas 72 are formed with detection grooves 73 that allow the identification ribs 28 and 38 to be inserted through the entire length at any of the upper, middle, and lower positions.

  In the detection unit 70 of the first male connector M, as shown in FIG. 8, the detection position 72 on the right side as viewed from the front corresponds to the position of the identification rib 28 of the first large sub-housing 20 and the center height position. The detection groove 73 is cut. On the other hand, in the detection region 72 on the left side, a detection groove 73 is cut at a lower position corresponding to the position of the identification rib 38 of the small sub-housing 30.

The second male connector Ma is used in correspondence with the second female connector Fa in the form in which the second large sub-housing 20a is inserted into the large accommodating chamber 11 of the frame 10 described above. Compared to M, the mounting configuration of the male terminal fitting is different from the shape of the detection unit 70a.
In the second male connector Ma, as shown in FIG. 9, a small male terminal 67 is provided in the cavity of the second large sub-housing 20a in a relatively wide area on the right side as viewed from the front in the hood portion 62 of the housing 60a. The small male terminals 67 are mounted in the arrangement corresponding to the cavities 31 of the small sub-housing 30 in the relatively narrow region on the left side as in the case of the first male connector M. .
About the detection part 70a, the detection groove | channel 73 is cut | disconnected in the lower position corresponding to the position of the identification rib 28 of the 2nd large subhousing 20a in the detection area 72 of the right side seen from the front. In the left detection region 72, a detection groove 73 is also cut at the lower position.

  The housings 60 and 60a of the first and second male connectors M and Ma described above are formed by insert molding using the male terminal fittings 66 and 67 as inserts, or the male terminal fittings 66 and 67 are attached by press fitting. In any case, each housing 60, 60a is individually molded in a separate mold. Each housing 60, 60a is attached to a printed circuit board as described above, and is attached to a wall surface of a device such as an ECU (Electronic Control Unit).

Then, the effect | action of this embodiment is demonstrated. In the normal usage, the first female connector F is fitted to the first male connector M, and the second female connector Fa is fitted to the second male connector Ma.
First, the case where the first and second male and female connectors F and M are fitted will be described. As shown in FIG. 7, the upper and lower levers 53 are attached to the frame 10 in a posture at the rotation start end and temporarily locked. As shown in FIG. 10, the first female connector F is accommodated by accommodating the first large sub-housing 20 in the large accommodating chamber 11 of the frame 10 and the small sub-housing 30 in the small accommodating chamber 12. Assembled. In this case, in the left identification area 49 as viewed from the front, the identification rib 28 of the first large sub-housing 20 faces the central height position, while in the right identification area 49, the small sub-housing is located in the lower position. Thirty identification ribs 38 face.

The first female connector F assembled in this manner is fitted to the first male connector M. The first female connector F is pushed in while sliding the rib 57 and the fitting groove 58 into the mating fitting groove 63 and the rib 64. At the same time, the detection unit 70 of the first male connector M enters the insertion window hole 45 of the frame 10. Here, a detection groove 73 is formed in the detection unit 70 at the center height position in the detection region 72 on the right side as viewed from the front, and in the lower position in the detection region 72 on the left side. Since the detection groove 73 is cut at a position corresponding to the height position of the identification ribs 28 and 38, the identification ribs 28 and 38 of both the sub-housings 20 and 30 pass through the detection groove 73 as shown in FIG. While continuing to be fitted.
When the predetermined amount is fitted, the follower pin 65 enters the inlet of the cam groove 54 and the temporary locking of the lever 53 is released. Therefore, when the lever 53 is subsequently rotated, the first female connector F is caused by the cam action. Is attracted to the first male connector M. When normal fitting is reached, the lever 53 is permanently locked, and the male and female connectors F and M are locked in the fitted state accordingly.

  When fitting the second male and female connectors Fa and Ma, the second large sub-housing 20a is accommodated in the large accommodating chamber 11 of the frame 10 in place of the first large sub-housing 20, so that the second The female connector Fa is assembled. In this case, as shown in FIG. 12, the identification ribs 28 of the second large sub-housing 20a and the identification ribs 38 of the small sub-housing 30 face the lower positions of both the left and right identification regions 49.

  When the second female connector Fa assembled in this way is fitted to the second male connector Ma, the detecting portion 70a of the second male connector Ma is similarly inserted into the insertion window hole 45 of the frame 10. In this detection unit 70a, a detection groove 73 is formed at the lower position of both the left and right detection areas 72. In other words, a position corresponding to the height position of the identification ribs 28 and 38 facing the identification area 49. Since the detection groove 73 is cut, the identification ribs 28 and 38 of both the sub-housings 20a and 30 are continuously fitted while being inserted through the detection groove 73 as shown in FIG. Similarly, normal operation is achieved by operating the lever 53.

Here, in assembling the second female connector Fa, the first large sub-housing 20 may be erroneously accommodated in the large accommodating chamber 11 of the frame 10. In that case, the first female connector F is substantially assembled. In that case, in particular, since the identification rib 28 of the first large sub-housing 20 faces the central height position of the identification area 49 on the left side when viewed from the front, it is fitted to the mating second male connector Ma. When the detection portion 70 enters the insertion window hole 45, the identification rib 28 of the first large sub-housing 20 is located above the detection groove 73 in the corresponding detection region 72, as shown in FIGS. A further contact is restricted by hitting the surface.
As a result, the second female connector Fa is not properly assembled, that is, the second large sub-housing 20a should be accommodated in the large accommodating chamber 11 of the frame 10, but the first large sub-housing 20 is erroneously accommodated. Is detected.

  When the second large sub-housing 20a is mistakenly accommodated in the large accommodating chamber 11 of the frame 10 when the first female connector F is assembled, the identification rib 28 of the second large sub-housing 20a and the first male connector M Since the position of the detection groove 73 of the detection unit 70 does not correspond, the identification rib 28 of the second large sub-housing 20a hits the lower surface of the detection groove 73 in the corresponding detection region 72, and the fitting is similarly restricted. Is done. With this, it is detected that the second large sub-housing 20a has been mistakenly accommodated in the large accommodating chamber 11 of the frame 10 where the first large sub-housing 20 should be accommodated.

  As described above, according to the present embodiment, whether or not the regular sub-housing 20 or 20a is properly accommodated in the large accommodating chamber 11 of the frame 10 is detected not with the frame 10 but with the opponent male. Since the detection is performed between the detection units 70 and 70a provided in the connectors M and Ma, the frame 10 can be shared by a single unit. Of course, the mating male connectors M and Ma need to be provided with detecting portions 70 and 70a in which the positions of the detection grooves 73 are different, but on the male connectors M and Ma sides, the number of poles and the types of male terminal fittings are different. If they are different, it is necessary to change the shape and the like of the housings 60 and 60a themselves. Therefore, if the shapes of the detection units 70 and 70a are changed at the same time, there will be no new burden. As a result, since the frame 10 can be shared, it is possible to cope with the low cost.

  When the regular sub-housings 20, 20a, and 30 are inserted, the male and female connectors are fitted straightly while the identification ribs 28 and 38 are in sliding contact with the detection grooves 73 of the other detection portions 70 and 70a. In other words, the two connectors can be fitted without being twisted, and in particular, it is possible to prevent the female connector from abutting against the male terminal fittings 66 and 67 protruding into the hood portion 62 to cause bending deformation.

  Further, the identification parts 26, 26a and 36 of the sub-housings 20, 20a and 30 housed in the frame 10 and the detection parts 70 and 70a provided on the mating male connectors M and Ma are fitted with male and female connectors. Engage relatively early. If a sub-housing other than a regular one is inserted, for example, further fitting is restricted before the temporary locking of the lever 53 is released, so that the forced fitting is continued as the lever 53 rotates. It is prevented. On the other hand, when the regular sub-housing is inserted, the function of preventing twisting can be exhibited from the early stage of fitting.
