Abstract

The objective is to allow for an assessment of whether or not a wire cover has been mounted in the correct fitting orientation. A wire cover (13) is provided on a back face of a female connector housing (8), fitted in two fitting orientations, a first and a second, with different wire (W) drawing directions of left and right with respect to the female connector housing (8). Detection tracks (26A, 26B) are formed in the female connector housing (8), where detection probes (29A, 29B) are inserted. A detection depression (25) is formed at an opening end portion of one of the side walls of the wire cover (13), and when the wire cover (13) is mounted in the second fitting orientation, the tip of the detection probe enters the detection depression (25) without interference, while when mounted in the first fitting orientation, the tip of the detection probe (29A, 29B) abuts and interferes with the opening end portion of the wire cover (13). This allows for an assessment of the fitting orientation in which the wire cover (13) is mounted.

Description

Connector with wire cover

The present invention relates to a connector with a wire cover.

There is a request that the wires drawn from the back of the connector housing should be led out in a desired direction in a state of being bundled. In order to meet such a demand, there is one in which an electric wire cover is mounted on the back surface of the connector housing. As an example, one disclosed in Patent Document 1 below is known.

In this case, an electric wire outlet is opened in a part of the electric wire cover, and the electric wires are concentrated and led out from here. In addition, in this prior art, two types of wire cover mounting postures can be selected such that the wire outlet port faces right or left so that the lead-out direction of the wire can be selected in two directions.

JP-A-8-298160

However, with the above, the mounting orientation can be selected, but there is a risk that it will be installed in the opposite direction to the normal mounting orientation. Then, there existed a problem that it flowed to an assembly process with an incorrect mounting posture.

The present invention has been completed based on the above circumstances, and provides a connector with an electric wire cover that can easily determine whether or not an electric wire cover is attached in a regular attachment posture. Objective.

The connector with an electric wire cover of the present invention includes a connector housing having a cavity for accommodating a plurality of terminal fittings, from which a plurality of electric wires connected to the terminal fitting can be led out from the back side, and an electric wire led out from the back side of the connector housing. And a first mounting posture in which the wire outlets are formed so as to open to the outside, and the opening directions of the wire outlets are opposite to each other with respect to the rear surface of the connector housing. An electric wire cover that can be selectively attached with the second attachment posture, and the connector housing is formed with a detection path through which a detection member can be inserted through the back surface of the connector housing. The wire cover is attached to one of the first and second mounting postures on the extension line of the detection path in FIG. Sometimes interfere with the detection member and the wire cover is to, when in other one of the mounting position, characterized in that the detecting portion serving as a non-interference is provided.

According to the present invention, the wire cover can be attached to the back surface of the connector housing by changing the direction of the wire outlet according to the required specifications. In that case, it is inspected whether or not the wire cover is attached as desired. In the inspection, the detection member is inserted into the detection path of the connector housing. At that time, the detection member may or may not interfere with the detection site depending on whether the wire cover is attached in the first attachment posture or the second attachment posture. With this difference, it is possible to determine whether or not the wire cover is mounted in a desired mounting posture. Therefore, it is possible to avoid a situation in which the electric wire cover is transferred to a subsequent process with an incorrect assembly posture.

A preferred embodiment of the present invention will be described.
(1) In the connector with an electric wire cover according to the present invention, a plurality of detection paths through which the detection members are inserted are formed in the connector housing, and either the first or second attachment is provided in the detection path. It is preferable that the detection member and the wire cover interfere with each other even when in the posture.
According to such a configuration, it is possible to determine whether the wire cover is in the first mounting posture or the second mounting posture based on the detection path corresponding to the detection site. In addition, forgetting to install the electric wire cover (or holding the electric wire cover) if the detection path includes a wire cover that does not correspond to the detection part and interferes with the electric wire cover regardless of the mounting position. If there is a case where there is no specification), the detection member inserted through the detection path becomes non-interfering, so that it is possible to determine a situation such as forgetting to mount.
(2) Further, the electric wire cover opens toward the back surface of the connector housing and surrounds and accommodates the electric wire led out from the connector housing, and communicates with the inside of the cover portion while communicating with the inside of the cover portion. The wire cover includes a correction portion that protrudes from the cover portion in a direction intersecting with the fitting direction of the connector housing and corrects the lead-out direction of the wire toward the protrusion direction, and the wire cover has an opening edge of the cover portion. The detection portion may be formed by being attached to the connector housing so as to face the back surface of the connector housing, and by cutting out a part of the opening edge of the cover portion. .
As described above, if the detection part is formed at the opening edge of the cover part, the opening edge of the cover part becomes a part of interference / non-interference with the detection member. Therefore, it is possible to avoid a situation in which the cover portion is deformed even when receiving the abutting force by the detection member.

<Example>
Next, an embodiment in which the connector with electric wire cover of the present invention is embodied will be described with reference to the drawings.

FIG. 1 shows the entire female connector F according to this embodiment. The female connector F has a female connector housing 8 made of synthetic resin. As shown in FIG. 2, the female connector housing 8 is formed in a block shape that can be fitted inside a male connector (not shown). As a whole, as shown in the figure, the main body portion 8A and a lever housing portion 8B disposed on one side (the upper side in the drawing) of the main body portion 8A are integrally formed.

A plurality of cavities 9 for accommodating female terminal fittings are formed in the main body 8A. As shown in FIG. 2, the cavities 9 are arranged in parallel in the height direction and the width direction.

2, 4, and 6, the lever accommodating portion 8 B is integrally formed with a width over substantially the entire surface on the upper surface side of the main body portion 8 A, and a lever 6, which will be described later, is formed in the inside. Is incorporated in a rotatable manner. The lever accommodating portion 8B is formed in a hollow frame shape that opens rearward in the fitting direction. As shown in FIG. 4 and the like, the lever accommodating portion 8B has an introduction opening 15 for introducing the cam follower on the male connector side into the lever accommodating portion 8B. An entrance groove 16 for introducing a release rib formed on the male connector side (not shown) is also opened near the end of the lever housing portion 8B.

Next, the lever 6 will be described. The lever 6 is also integrally formed of a synthetic resin material. The lever 6 is formed in a substantially plate shape that can be accommodated in the lever accommodating portion 8B, and is rotatably attached around the rotation shaft 19 on the bottom surface in the lever accommodating portion 8B.

A locking arm 21 is formed on the periphery of the lever 6 through a slit 20 and can be bent toward the slit 20 side. As shown in FIG. 1 and the like, the locking arm 21 extends toward the side wall in the lever housing portion 8B, and the distal end of the locking arm 21 is locked to the locking projection 22 formed to protrude from the side wall in the lever housing portion 8B. It is possible. The lever 6 is held in a state in which the clockwise rotation shown in FIG. 1 is restricted by the locking arm 21 being locked to the locking projection 22. Hereinafter, the position of the lever 6 shown in FIGS. However, since the engagement margin in the thickness direction between the locking arm 21 and the locking projection 22 is small and the locking surface 22A of the locking projection 22 is a tapered surface, The release of the male connector is brought into contact with the fitting of the connector so that the lever 6 can be released. By releasing this engagement, the lever 6 is allowed to rotate. Further, when the lever 6 is in the initial position, the counterclockwise rotation shown in the figure is restricted by the peripheral portion of the lever 6 opposite to the locking arm 21 interfering with the inner wall of the lever housing portion 8B. Yes.

As shown in FIGS. 1, 4, and 6, a cam groove 23 is formed in the lever 6, and one end (entrance) of the lever 6 opens at the peripheral edge of the lever 6. As shown in FIG. 4, when the lever 6 is in the initial position, one end side of the cam groove 23 is exposed in the middle of the introduction opening 15 of the lever accommodating portion 8B. At this time, the opening (inlet) of the cam groove 23 faces forward in the fitting direction. Thus, when the male and female connectors are shallowly fitted while the lever 6 is held at the initial position, the cam follower provided on the male connector can enter the inlet of the cam groove 23.

Also, as shown in FIGS. 4 and 6, the lever 6 is formed with a deflectable lock arm 17. When the lever 6 is rotated from the initial position until the male and female connectors are properly fitted, the lock arm 17 is moved to the lever housing portion 8B at this turning position (fitting completion position). By engaging with the side, the lever 6 is releasably held at its rotational position (fitting completion position).

Mounting claws 14 for attaching the wire cover 13 to the female connector housing 8 are provided on the back side of the main body 8A at a total of six locations in the center in the width direction of the four corners, the upper edge, and the lower edge (see FIG. 6 shows only those provided on the upper side of the four corners). Each attachment claw 14 protrudes rearward in the fitting direction from the back surface of the main body 8A. The electric wire cover 13 is for correcting each electric wire W drawn from the back surface of the female connector housing 8 in a set lead-out direction.

Next, the configuration of the electric wire cover 13 will be described. The electric wire cover 13 is made of synthetic resin, and as shown in FIGS. 8 to 10, the cover portion 13A covering the electric wire W and the lead-out direction of the electric wire W are corrected. It is integrally formed from the correction part 13B to do.

The cover portion 13 A is formed in a cap shape that opens toward the back surface of the main body portion 8 A of the female connector housing 8, and can collectively accommodate a group of wires drawn from the back surface of the female connector housing 8. 13 A of cover parts are formed so that the rear surface side in the state mounted to the female connector housing 8 may bulge back, and the wire W is drawn out on one side in the width direction (left and right direction in FIGS. 8 and 9) of this bulged portion. The mouth 30 is open. In this figure, a notch is formed over a range from the top of the bulging portion of the cover portion 13A to the opening edge. Moreover, the said correction | amendment part 13B protrudes toward the outward in the fitting direction in the figure (top side of a bulging part). The correction portion 13B extends in an oblique direction with respect to the fitting direction. The electric wire W drawn out from the back surface of the female connector housing 8 is led in an oblique direction along the correction portion 13B, and is wound with tape together with the correction portion 13B.

Further, as shown in FIG. 10, mounting protrusions 24 are formed inwardly at positions corresponding to the mounting claws 14 at the opening edge of the cover portion 13A. The mounting projections 24 and the mounting claws 14 can lock the electric wire cover in either the mounting posture shown in FIG. 1 or the mounting posture shown in FIG. That is, the wire cover 13 has an attachment posture (first attachment posture) in which the correction portion 13B (drawer port 30) faces one side in the width direction (left side shown in FIG. 1) and the correction portion 13B with respect to the back surface of the female connector housing 8. It is possible to select and attach two attachment postures, that is, an attachment posture (second attachment posture) that faces the other side in the width direction (the right side shown in FIG. 4). Moreover, in the case of mounting in any mounting posture, the opening edge of the cover portion 13A is in contact with the back surface of the female connector housing 8 over almost the entire circumference.

In addition, as shown in FIG. 10, the predetermined mounting protrusion 24 is provided with a punch hole 28 in the cover portion 13A to enable these moldings.

Further, as shown in FIG. 9, a detection recess 25 (detection site) is provided at the opening edge of one of the side walls located on the long side in the cover portion 13A. The detection recess 25 is cut out at a portion of the side edge that is close to the extraction port 30 by a predetermined distance from the center in the width direction. The detection recess 25 is formed in a substantially rectangular shape, and opens toward the back side of the female connector housing 8 when the wire cover 13 is attached to the female connector housing 8.

On the other hand, as shown in FIG. 2, the front end sides of the two

detection paths

26A and 26B are opened on the fitting surface (front surface) of the female connector housing 8 to form

detection windows

27A and 27B. As shown in FIG. 3, a pair of

detection probes

29A and 29B can be inserted into both

detection paths

26A and 26B through both

detection windows

27A and 27B. Both

detection windows

27A and 27B are arranged at a height position that is substantially a boundary between the main body portion 8A of the female connector housing 8 and the lever housing portion 8B. One detection window 27A is arranged on the center line in the width direction of the female connector housing 8, and the other detection window 27B is arranged so as to be shifted from the center line in one direction in the width direction (to the right in FIG. 2) by a certain distance. ing.

As shown in FIGS. 3 and 5, both detection paths 26 A and 26 B both extend along the fitting direction, and the rear end side penetrates the back surface of the female connector housing 8. Both

detection paths

26A and 26B are formed in the female connector housing 8 so as to be sufficiently wider than the opening width of the detection window, and open to the back surface with the same opening width. When both of the

detection paths

26A and 26B are shifted from the center in the width direction to one side (eccentric side detection path 26B), as shown in FIG. 5, when the wire cover 13 is mounted in the second mounting posture, The detection recess 25 is positioned on the extension line, and the tip of the detection probe 29B enters the detection recess 25 so as not to interfere. However, as shown in FIG. 3, when the wire cover 13 is mounted in the first mounting posture, the detection probe 29 B is not in communication with the detection recess 25, so the detection probe 29 B opens the cover portion 13 A of the wire cover 13. It hits the edge and interferes.

On the other hand, as shown in FIGS. 3 and 5, the detection path 26 A, 26 B located at the center in the width direction (the center side detection path 26 A) has the electric wire cover 13 attached to either the first or second attachment. Even when mounted in a posture, the detection recess 25 is not in communication, and the tip of the detection probe 29 A interferes with the opening edge of the wire cover 13.

Both

detection probes

29A and 29B are both connected to a detection circuit provided in a detection device (not shown). Depending on whether or not the detection probes 29A and 29B protrude from the female connector housing 8, they are turned on and off. The switching means for detecting is configured. In the case of the present embodiment, it is detected as an off state when it protrudes (non-interference with the wire cover 13), and is detected as an on state when it does not protrude (a state that interferes with the wire cover 13).

Next, the function and effect of the present embodiment configured as described above will be described. The female connector selects whether the electric wire cover 13 is set to the first mounting posture or the second mounting posture according to the required specifications. When the first mounting posture shown in FIG. 1 or the like is selected, the outlet 30 and the correction portion 13B of the wire cover 13 are opposed to the back surface of the female connector housing 8 in the left-facing posture as shown in FIG. Let Then, the electric wires W drawn from the back surface of the female connector housing 8 are bundled and accommodated in the cover portion 13 A, and are drawn from the lead-out port 30. In this state, when the mounting protrusions 24 and the corresponding mounting claws 14 are locked, the wire cover 13 is mounted on the female connector housing 8 in the first mounting posture. Thus, the electric wire W drawn out from the outlet 30 is tape-wound together with the correction portion 13B, and as a result, the electric wire W is externally corrected in the illustrated diagonally rearward direction with respect to the fitting direction as shown in FIG. Derived toward

When it is selected that the electric wire cover 13 is to be mounted in the second mounting posture shown in FIG. 4, the drawer port 30 and the correction portion 13B are directed diagonally rearward as shown in FIG. And the female connector housing 8 may be attached.

Inspecting whether or not the female connector F in the state in which the electric wire cover 13 is mounted is attached in the mounting posture as per the required specifications before being brought into the fitting site with the male connector. Is made.

As shown in FIG. 3, when the wire cover 13 is mounted in the first mounting posture, the detection probes 29A and 29B are respectively connected to the

detection paths

26A and 26B through the

detection windows

27A and 27B of the female connector housing 8. It is inserted. When the wire cover 13 is in the first mounting posture, the opening edge of the cover portion 13A is located in close contact with both rear ends of the

detection paths

26A and 26B. Therefore, when both

detection probes

29A and 29B are inserted, they both strike the opening edge of the cover portion 13A (interference state). For this reason, both

detection probe

29A, 29B will be in an ON state, and, thereby, it will be determined with the detection apparatus that the electric wire cover 13 is mounted | worn with the 1st attachment attitude | position.

On the other hand, as shown in FIG. 5, when the wire cover 13 is mounted in the second mounting posture, the

detection probe

29A, 29B, which is inserted into the central detection path 26A, is the cover portion 13A. However, since the object 29B inserted into the eccentric side detection path 26B enters the detection recess 25 and enters a non-interference state, it is detected as an off state on the eccentric side. Is done. As a result, the detection device determines that the wire cover 13 is mounted in the second mounting posture.

Further, as shown in FIG. 7, in the case where the electric wire cover 13 is not installed or the electric wire cover 13 is not attached, both

detection probes

29A and 29B are protruded rearward from the female connector housing 8 (non-interference state). Both are turned off. Thus, the detection device determines that the wire cover 13 is not attached to the female connector housing 8.

As described above, according to the present embodiment, whether the wire cover 13 is in the first mounting posture or the second mounting posture due to the difference between the protruding lengths of the detection probes 29A and 29B, or even non- It is possible to reliably determine whether it is a specification for mounting. Therefore, the electric wire cover 13 does not flow to the subsequent process with an incorrect specification.

In this embodiment, the interference part of the detection probes 29A and 29B with respect to the wire cover 13 is set at the opening edge of the cover part 13A. That is, since the wire cover 13 receives the abutting force from the detection probes 29A and 29B at the opening edge of the cover portion 13A, the wire cover 13 can be protected from deformation.
