Description

  The present invention relates to a connector provided with an electric wire cover.

In this type of connector, by attaching a cover to the rear surface of the housing in which the terminal fittings fixed to the ends of the electric wires are accommodated, the electric wire group drawn from the rear surface of the housing is accommodated and led out in a predetermined direction. (For example, refer to Patent Document 1).
Here, as means for attaching the cover, there are various types such as a slide type and a fitting type from the rear. In the following cases, the rotary type is convenient.

For example, when inspecting whether or not male and female terminal fittings respectively attached to male and female connectors are properly electrically connected, it is necessary to conduct a continuity test with both connectors fitted. The inspection pin must be inserted from the rear side and applied to the terminal fitting. At that time, if the cover is attached to the rear surface of the housing, it is necessary to remove the cover, but if it is completely removed, it is troublesome to attach again and there is a risk of losing it. It is advantageous to be able to open the rear surface while leaving it on. Such a rotation type cover has an insertion groove through which an electric wire is inserted at one end side, and the other end side is pivotally supported with respect to the housing, while the opening end side is locked to the housing. It has been common to provide a locking portion.

<Embodiment>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
In this embodiment, an ECU (Electronic Control Unit) collective connector is shown as an example. As shown in FIGS. 1 and 2, as shown in FIG. Male connectors 10 are arranged side by side, and a female connector 20 with a cover 60 is fitted to each male connector 10. A plurality of ECU cases C are installed side by side.

First, the male connector 10 will be described. The male connector 10 is a board connector mounted on a printed circuit board K (hereinafter referred to as a board K), and a plurality of male terminal fittings 12 are mounted on a male housing 11 made of synthetic resin. As shown in FIGS. 3 and 4, the male housing 11 is formed in a horizontally long shape with a fitting recess 13 opened on the front surface, and a plurality of terminals are provided on a base wall 14 which is the back wall of the fitting recess 13. The insertion holes 15 are divided into two upper and lower stages, and are formed so as to be staggered vertically.
One end of each tab-shaped male terminal fitting 12 is inserted into each terminal insertion hole 15 and protrudes in alignment with the fitting recess 13, and the other end of each male terminal fitting 12 extends from the base wall 14. It protrudes rearward, is bent at a right angle downward from a predetermined position, and is further bent at a right angle at the rear to form a connecting portion 12A.

The male connector 10 is placed at a predetermined position on the end of the board K with the fitting recess 13 facing outward, and the fixing brackets 16 mounted on both sides are soldered onto the board K. At the same time, the connection portions 12A of the male terminal fittings 12 are soldered and connected to the corresponding conductive paths on the substrate K.
Thus, the board | substrate K which mounted the male connector 10 is accommodated in ECU case C, and each male connector 10 fits and faces the window hole Ca opened on one surface of case C in connection with it.

  Next, the female connector 20 will be described. The female connector 20 includes a female housing 21 made of synthetic resin. The female housing 21 is a horizontally long shape that can be fitted into the fitting recess 13 of the male housing 11 as shown in FIGS. 3 and 5. It is formed in a block shape. In the female housing 21, as shown in FIG. 6, a plurality of cavities 22 for accommodating the female terminal fittings 30 correspond to the arrangement of the male terminal fittings 12 of the male connector 10 described above, and are divided into two upper and lower stages. It is formed in a staggered arrangement at the top and bottom.

The female terminal fitting 30 has a shape including an elastic contact piece 32 that can come into contact with the mating male terminal fitting 12 in a main body 31 that has a rectangular tube shape, and a barrel 33 provided behind the main body 31. 34 is fixed to the end of the electric wire W by caulking.
When the female terminal fitting 30 is inserted into the cavity 22 from the rear and reaches the normal position, the lance 23 provided on the bottom wall of the cavity 22 is elastically engaged with the engaging portion 36 provided on the main body 31. Stop. Further, a side-type retainer 25 is mounted on the lower surface of the female housing 21, and when the retainer 25 is pushed to the full locking position, the locking projection 26 is locked to the jaw portion 37 of the main body 31, As a result, the female terminal fitting 30 is housed in the cavity 22 while being prevented from coming off twice. The electric wire W is drawn backward from the inlet 22 </ b> A of the cavity 22. Further, on the rear surface of the female housing 21, a tester insertion port 28 for inserting the test pin Tp of the tester T is opened to the inlet 22 </ b> A of the cavity 22 at a position close to one side of the lower edge of the inlet 22 </ b> A of each cavity 22. Is formed.

A lock arm 40 is provided at the center of the upper surface of the female housing 21 in the width direction. As shown in FIG. 7, the lock arm 40 is formed so that a release operation portion 42 protrudes in the width direction at the rear end of the arm body 41 that is raised from the front edge side and then folded back. The projecting end is connected to a protective wall 43 standing on the upper surface of the female housing 21 and can be elastically displaced in the vertical direction by a so-called three-point support structure. On the arm main body 41 of the lock arm 40, a lock portion 44 that is engaged with the locked portion 16 formed on the upper surface of the fitting recess 13 of the male housing 11 is formed.
In addition, a finger hooking portion 46 is formed so as to protrude from the center portion in the width direction at the lower rear edge of the female housing 21.

A synthetic resin cover 60 is mounted on the rear surface side of the female housing 21. The cover 60 mainly functions to collect the electric wires W drawn from the rear surface of the female housing 21 and lead them out in a predetermined direction. As shown in FIG. It is formed in a long and narrow box shape that can cover the rear surface by striking.
The cover 60 is also a pivotable opening / closing type. For this reason, shafts 50 are erected from both the upper and lower surfaces of the left and right ends of the female housing 21 with the center in the width direction on the rear edge side.

  The shaft 50 is paired up and down, and also serves as a locking portion for locking the cover 60 in a closed state as will be described later. For this reason, each shaft 50 has a flat front surface (front side in FIG. 7) on the base side where the predetermined dimension of the protruding end remains, and forms a locking surface 51 (see FIG. 12). . In addition, a protruding protrusion 52 is formed at the protruding end of each shaft 50 so as to face each other on the left and right. In short, when one of the left and right upper and lower shafts 50 functions as a pivot shaft of the cover 60, the other upper and lower shafts 50 function as a locking portion that holds the cover 60 in a closed state. It has become.

  The cover 60 will be described again with reference to FIGS. In the cover 60, a corner on one side in the length direction on the ceiling surface (left side in FIG. 11) is formed obliquely. On the inclined side, an insertion groove 61 that is cut from the end surface to the center of the ceiling surface and through which the electric wire W can be inserted is formed. In other words, the side on which the insertion groove 61 is formed is the opening end 60 </ b> A of the cover 60.

At the opening end 60 </ b> A, bearing plates 64 </ b> A and 64 </ b> B are formed so as to protrude from the outer surface of the side plates 62 beyond the opening edge 63 of the cover 60. Both the bearing plates 64A and 64B are formed with a space at which the rear surface side of the female housing 21 can be sandwiched up and down, and are tightly and rotated on the shaft 50 at a position protruding the opening edge 63 by a predetermined dimension. A shaft hole 65 to be fitted is formed.
Both shaft holes 65 are formed with cutout holes 66 at the front edges of the bearing plates 64A and 64B in the protruding direction so that the retaining protrusions 52 of the shaft 50 can be fitted and released. Further, in one bearing plate 64B, a cut groove 67 reaching the base end side from the shaft hole 65 is cut. As the cutting groove 67 is cut, it is easily bent and deformed.

At the end of the cover 60 opposite to the opening end 60A, as shown in FIG. 11, the half of the end surface on the ceiling side is left and the both side plates 62 are connected, that is, the closed end 60B. On the closed end 60B side, the side plate 62 is also shortened.
On the closed end 60 </ b> B side, a locking piece 70 projects from the outer surface of the shortened both side plates 62 beyond the opening edge 63 of the cover 60. Both locking pieces 70 are also formed with a space at which the rear side of the female housing 21 can be sandwiched up and down, and the protruding ends of the locking pieces 70 are bent at right angles to the opposite side of the bearing plates 64A and 64B. A portion 71 is formed and can be locked to the locking surface 51 of the shaft 50 as shown in FIG.

Both locking pieces 70 are connected by a pressing operation unit 73. As shown in FIGS. 10 and 13, the pressing operation portion 73 slightly protrudes outward from the outer surface on the protruding end side of both locking pieces 70, and then extends toward the protruding direction of the flange portion 71. The extension ends are connected by a pressing wall 74. On the protruding end side (front side in FIG. 13) of the locking piece 70 in the pressing wall 74, the central portion in the width direction is cut off.
When the pressing wall 74 of the pressing operation portion 73 is pressed in the direction of the arrow in FIG. 13, both the locking pieces 70 can be bent and deformed so that the flange portion 71 approaches the bearing plates 64A and 64B. Further, the remaining portion of the pressing wall 74 functions to protect both the locking pieces 70, particularly the front part of the flange 71.

  An electric wire outlet 76 is formed at a substantially central portion in the length direction on the ceiling surface of the cover 60. As shown in FIG. 8, the wire outlet 76 is formed in a wide and substantially groove shape, and is formed with one side edge of the insertion groove 61, that is, a bearing plate 64 </ b> A in which the slit groove 67 is not formed. From the side edge on the side, an angle of about 60 degrees is formed with the opening edge 63, and it is formed in an oblique posture inclined toward the opening end 60A. As shown in FIG. 19, the electric wires W drawn from the rear surface of the female housing 21 are stored together in a uniform state in the electric wire outlet port 76. The center x, in other words, the center x of the wire outlet 76 is set to be offset from the center X in the width direction of the cover 60 by a predetermined dimension s. Note that the wire outlet 76 is within the width of the pressing operation portion 73 that is the maximum width portion of the cover 60.

  A finger holder 78 is formed at the center of the side plates 62 of the cover 60. As will be described later, when the cover 60 is mounted on the rear surface of the female housing 21, the finger holder 78 is positioned immediately behind the release operation portion 42 of the lock arm 40 provided on the female housing 21. As shown in FIG. 3, the front side is a concave portion 79 that is recessed from the release operation portion 42, and the rear side is a high-level portion 80.

Then, the effect | action of this embodiment is demonstrated.
On the female connector 20 side, the female terminal fitting 30 is inserted into the cavity 22 of the female housing 21 (see FIG. 6). The electric wires W drawn out to the rear surface side of the female housing 21 are almost put together. Subsequently, as shown in FIG. 13, the cover 60 is arranged in a substantially orthogonal posture on the rear surface side of the female housing 21 on the rear surface side of the female housing 21, for example, on the left side as viewed from the rear surface, while passing the wire group Wa from the opening end 60 </ b> A side. In particular, the relief hole 66 of the shaft hole 65 and the retaining protrusion 52 of the shaft 50 are arranged in the same direction.

  Subsequently, when the bearing plates 64A and 64B of the cover 60 are pushed toward the shaft 50, both the bearing plates 64A and 64B pass through the outside of the protruding end of the shaft 50 while being elastically opened, and when a predetermined amount is pushed, FIG. As shown in FIG. 4, the bearing plates 64A and 64B are restored to their original shapes while allowing the retaining projection 52 to escape into the escape hole 66, and the base side of the shaft 50 is fitted into the shaft hole 65 of the bearing plates 64A and 64B. 60 is rotatably supported. At the same time, the wire group Wa is fitted into the wire outlet 76.

  Next, the cover 60 is rotated toward the front side of FIG. 14 while the electric wire group Wa is pulled out from the electric wire outlet port 76. If it rotates even a little, the lip of the shaft hole 65 is locked to the retaining protrusion 52 and is prevented from coming off. When the opening edge 63 of the cover 60 is pivoted slightly before it hits the peripheral edge of the rear surface of the female housing 21, the collar portion 71 of the locking piece 70 hits the opposite shaft 50 and elastically deforms together with the pressing operation portion 73, and the female housing 21, the collar 71 passes through the shaft 50, and the collar 71 is locked to the locking surface 51 of the shaft 50 in a wide area as shown in FIG. To do. As a result, as shown in FIG. 15, the cover 60 is mounted and locked so as to cover the rear surface of the female housing 21.

Subsequently, a continuity test is performed. In that case, the female connector 20 to which the cover 60 is mounted as described above is fitted to the mating male connector 10 facing the window hole Ca of the ECU case C. When the female housing 21 is pushed in while deforming and deforming the lock arm 40 and is pushed in a normal amount, the lock arm 40 is restored and the lock portion 44 is locked to the rear surface of the locked portion 16 as shown in FIG. By this, it locks to a fitting state, and the corresponding male and female terminal metal fittings 12 and 30 are also connected normally.
At this time, if the finger holding part 78 of the cover 60 is held, the release operation part 42 of the lock arm 40 is not touched, so that when the lock is applied, the lock arm 40 moves back vigorously, and the locking sound A good lock feeling can be obtained.

  Next, the cover 60 is once opened. For this purpose, when the pressing operation portion 73 is pressed in the direction of the arrow in FIG. 12A, the locking piece 70 is elastically displaced as shown in FIG. The cover 60 is released from the stop surface 51 and the cover 60 is unlocked. Then, the cover 60 is rotated in the opposite direction to the above and opened. At this time, for example, as shown in FIG. 17, when the cover 60 is rotated further beyond the initial mounting posture, the retaining protrusion 52 of the shaft 50 is locked to the lip of the shaft hole 65. Therefore, the cover 60 is prevented from being removed carelessly.

  When the cover 60 is thus opened, the test pin Tp of the tester T is inserted into the tester insertion port 28 provided in communication with the cavity 22 as shown by the chain line in FIG. 6 and FIG. The inserted inspection pin Tp is guided to approach the female terminal fitting 30 along the tapered guide surface 29 formed on the bottom surface, and is pressed against and contacted with the outer surface of the insulation barrel 34. Thereby, a continuity test is normally performed.

  When the continuity test is completed, the female connector 20 is once disconnected from the mating male connector 10. For this purpose, the lock arm 40 is forcibly elastically displaced by pressing the release operation part 42 from the state shown in FIG. 16, and the locking of the lock part 44 to the locked part 16 is released. Subsequently, the female connector 20 is pulled out from the male connector 10 together with the cover 60 by pulling the cover 60 with the finger holding portion 78. Since the finger holding portion 78 has a recess 79 immediately after the release operation portion 42, it is possible to smoothly push the release operation portion 42 while sinking a finger into the recess 79, and subsequently pull the cover 60. At that time, it is possible to efficiently perform a pulling operation by placing a finger on the high-order portion 80 at the rear thereof.

  When the female connector 20 is removed in this manner, the electric wire group Wa led out from the cover 60 is aligned again and fitted into the electric wire outlet 76, and the tape 82 is wound around the electric wire outlet 76 and fixed as shown in FIG. . Accordingly, as shown in FIG. 19, it is determined that the center x of the derived wire group Wa comes to a position offset from the center X in the width direction of the cover 60 by the dimension s.

In FIG. 7, the cover 60 is turned upside down and disposed on the left side as viewed from the front on the rear surface side of the female housing 21, and the cover 60 is rotatably supported with respect to the left shaft 50 as viewed from the front. When mounted so as to be locked to the opposite shaft 50, the wire lead-out port 76 of the cover 60 protrudes in the direction opposite to the left and right, so that the wire group Wa is led out in the opposite direction to the left and right. be able to.
Similarly, the cover 60 can be opened with the female housing 21 left open to conduct a continuity test, and the wire group Wa can be taped along the wire outlet port 76 to determine the offset of the wire group Wa.

  The ECU case C is installed vertically, for example, as shown in FIG. 1, and the female connector 20 with the cover 60 is fitted to the mating male connector 10 provided facing the side surface as described above. Is done. At this time, on the female connector 20 side, the cover 60 is mounted in the reverse direction, that is, the wire group Wa is led out in the reverse direction. For example, as shown in FIG. 20 and FIG. The female connector 20 in which the wire group Wa is led out obliquely upward is provided for the upper two male connectors 10, and the female connector 20 in which the wire group Wa is led obliquely downward is provided in the lowermost male connector 10. The connector 20 is used by being assembled such that the connector 20 is fitted.

Thereafter, the female connector 20 may be removed from the ECU case C for maintenance or the like. At that time, as described above, the lock arm 40 is forcibly bent and deformed to release the lock, and then the female connector 20 is pulled out. At this time, for example, when the upper female connector 20 is removed while leaving the middle female connector 20, the electric wire group Wa led out from the middle female connector 20 is located behind the upper female connector 20 (front side in FIG. 21). Is in a state to pass.
However, since the center x of the wire group Wa is derived from a position offset from the center X in the width direction of the cover 60 by the dimension s on the left side of the figure, when the upper female connector 20 is pulled out, the middle stage The degree of interference with the wire group Wa led out from the female connector 20 is small, and the upper female connector 20 can be removed relatively smoothly.

  As described above, according to the present embodiment, the rotation type cover 60 is rotatably supported on the opening end 60A side and locked on the closing end 60B side. That is, on the closed end 60B side, since the rigidity is secured and the electric wire group Wa is prevented from being opened even if it is pulled to the side, it is difficult to release the lock, and thus the locking force of the cover 60 is increased. Can be increased.

  On the other hand, the locking of the cover 60 is released by pressing the pressing operation portion 73 to bend and deform both locking pieces 70. Here, when the female connector 20 with the horizontally long cover 60 as in the present embodiment is fitted to and detached from the mating male connector 10, the both side plates 62 of the cover 60 are often picked. . Therefore, in this embodiment, since the pressing operation unit 73 is disposed on the end surface adjacent to the side plate 62 of the cover 60, the pressing operation unit 73 is inadvertently unlikely to be touched during fitting / detaching operation. It is prevented that 73 is pressed to release the lock. Moreover, since both the locking pieces 70 can be bent and deformed by pressing the pressing operation portion 73, the releasing operation itself is simple.

In addition, the pressing operation portion 73 is provided so as to protect the locking piece 70, that is, the portion locked to the counterpart shaft 50. The stop is prevented from being inadvertently removed.
Since the cover 60 can be rotatably mounted on the rear surface of the female housing 21 in a posture opposite to the length direction, the lead-out direction of the wire group Wa can be changed with the same cover 60. it can.
