[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a structure for mounting a terminal to a connector cover in a lever-coupled connector device for coupling a connector utilizing the leverage of an arm.

[0002]

2. Description of the Related Art A connector device of this kind has an advantage that a multi-pole connector can be connected with a small force because the leverage of an arm is used. The general structure thereof is known, for example, in Japanese Patent Application Laid-Open No. 4-56084, and is roughly as follows.

That is, for example, a large number of male terminals are arranged in a fixed-side male connector housing, and a large number of female terminals are arranged in an insertion-side connector housing. An arm for performing the "lever action" is rotatably provided on the connector housing on the insertion side, and a cover provided with an engaging projection for engaging with the arm is mounted on the insertion side connector housing. By rotating the arm in a state where the arm is engaged with the engagement protrusion provided on the cover, the cover and, by extension, the connector housing on the insertion side are pushed down by the "lever action" of the arm, and the two connectors are connected. Is performed.

In this type of connector device,
In order to detect whether or not both connectors are securely connected, a configuration is provided in which a pair of detection terminals are provided on a side surface of a cover, and a short bar for short-circuiting between the detection terminals is provided on the arm. When the arm is moved to the position where the two connectors are completely connected,
The shorting bar of the arm causes a short circuit between the two detection terminals, thereby detecting the connection of the connector.

FIG. 13 shows a configuration for attaching a detection terminal to a cover in such a connector device.
And FIG. 14 are known. This is cover 1
A pair of terminal insertion holes 2 are formed at the rear end of the terminal, and the detection terminal 3 is inserted into the terminal insertion hole 2 from behind. A locking recess 2a is provided in the terminal insertion hole 2.
Are formed, and the detection terminal 3 is provided with a locking piece 3a which is engaged with the locking recess 2a. The locking piece 3a of the detection terminal 3 inserted into the terminal insertion hole 2 engages with the locking recess 2a of the terminal insertion hole 2 to prevent the terminal 3 from falling off.

[0006]

However, in the above-described structure for preventing the detection terminal 3 from coming off, which is called a terminal lance, the engagement between the locking piece 3a and the engaging recess 2a may be released from the outside. Because it is difficult, the terminal 3 once inserted cannot be taken out for, for example, maintenance or the like.
Could be bent and lead to damage to Terminal 3.

In order to avoid such difficulties in maintenance, a storage recess for storing the detection terminal is formed in the cover, and a lid closing the storage recess in a state in which the detection terminal is stored is provided with a hinge portion. A configuration conceivably provided integrally with the cover via the cover is conceivable. With this configuration, if the lid is opened, the detection terminal can be taken out without damaging it, so that the maintenance should be extremely simple.

However, this configuration has a problem that the mounting of the detection terminal becomes difficult and the assemblability deteriorates. That is, in the configuration employing the terminal lance as shown in FIG. 13, the user holds the cover with one hand, picks up the electric wire 4 with the other hand, and simply inserts the detection terminal 3 into the terminal insertion hole 2 of the cover 1 later. The terminal does not fall out even if you release your hand on the way. However, in the structure in which the detection terminal is stored in the storage recess, even if the detection terminal is stored in the storage recess by holding the cover with one hand and picking up the electric wire with the other hand, the wire is picked because the entire storage recess is open. If the hand is released, the weight of the wire will cause the detection terminal to easily come off the storage recess. Therefore, it is necessary to store the detection terminal in the storage recess, hold down the detection terminal with fingers so as not to fall off, and close the lid to fix the detection terminal.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is therefore an object of the present invention to provide a connector which is easy to remove a detection terminal once installed, has excellent maintenance workability, and is excellent in assemblability. An object of the present invention is to provide a structure for attaching a terminal to a cover.

[0010]

According to the present invention, a terminal mounting structure for a connector cover is provided by rotatably providing an arm to one connector housing and pressing down the cover over the other connector housing by the arm. While coupling the two connectors, in which the cover holds a detection terminal for detecting that the arm is at the coupling position, a moderating protrusion for engaging and holding the arm on the side of the cover is provided, A storage recess for holding the detection terminal is formed adjacent to the moderation protrusion, and a lid body for covering and fixing the detection terminal housed in the storage recess is integrally provided via a hinge portion. Is connected to the lower part of the moderating projection so that the tip of the detection terminal projects below the moderating projection, and Characterized in was constituting the tip of the detection terminals and formed flat band so as to obliquely inserted into the lower region of the detent projection.

[0011]

When mounting the detection terminal on the cover, the following operation is performed. Since the storage recess is connected to the lower portion of the moderating protrusion and the lower region of the moderating protrusion is formed flat, the tip of the detection terminal can be obliquely inserted into the lower region of the moderating protrusion. . Then, the detection terminal is obliquely inserted into the storage recess so that the tip is located in the lower region of the moderation protrusion, and the detection terminal is rotated with the end of the moderation protrusion on the storage recess side serving as a fulcrum. The terminal is housed in the housing recess, and the terminal is temporarily held while being in contact with the moderation protrusion. For this reason, even if the hand is released from the detection terminal in this state, the terminal does not come off from the storage recess, and the work of closing the lid, covering the detection terminal, and fixing it here can be easily performed. become able to.

When the detection terminal is detached for maintenance or the like, the terminal can be taken out without damaging the cover by opening the lid, thereby facilitating the maintenance work.

[0013]

As described above, according to the present invention, the detection terminal can be temporarily held in the storage recess by using the moderating projection, so that the assembling property is excellent, and the detection terminal can be easily removed after being attached. This has the effect of excellent maintenance workability.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The overall structure is shown in FIG. 12, and a male terminal (not shown) is provided in the fixed-side connector housing 11, and this is held by the retainer 12. A female terminal (not shown) is provided in the connector housing 13 on the insertion side.
Is held at. Above the fixed side connector housing 11, a bipedal arm 15 is provided rotatably around a bearing hole 15a. The distal end of the arm 15 is continuous in a bridge shape, and a U-shaped short bar 16 is provided between the distal ends through the bridge 15b.

A cover 17 is provided on the connector housing 13 on the insertion side. This is configured to cover a group of electric wires (not shown) connected to the female terminal of the connector housing 13 so that the group of electric wires is led out horizontally from the right side in FIG. 12 and the upper surface on the front side is obliquely downward. Inclined and tapered. Engagement pieces 18 having two engagement holes 18a are provided on both right and left sides of the cover 17 so as to project downward, and engage with engagement projections 19 provided on the side of the insertion side connector housing 13. It is supposed to. Further, two guide projections 20 are provided downward on both right and left sides of the lower surface of the cover 17, respectively, and are inserted into receiving holes 21 formed on the upper surface of the insertion-side connector housing 13. Thereby, the position of the wire group in the cover 17 is regulated, and the expansion deformation of the cover 17 is prevented.

A pair of cam projections 22 project laterally at the center of the side of the cover 17. This is because when the connector on the insertion side is inserted into the connector on the fixed side with the cover 17 attached, the two cam grooves 23 formed near the base of the arm 15 are engaged. When the arm 15 is rotated in the mating state, the connector housing 13 on the insertion side is pushed down, so that the two connectors can be completely connected. The situation is as illustrated in FIG. First, as shown in FIG.
The insertion side connector housing 13 to which the cover 17 is attached is fixed to the fixed side connector housing 1
Address to 1. Then, the cam projection 22 enters into the cam groove 23 of the arm 15 as shown in FIG. Therefore,
When the arm 15 is rotated in the direction of the arrow, the cam projection 22 is introduced into the cam groove 23, and is pushed by the edge of the cam groove 23, so that the cam projection 22 and the entire cover 17 are strongly pushed down. As a result, the insertion-side connector housing 13 is pushed down by the cover 17, and the female terminal group provided here and the male terminal group provided in the fixed-side connector housing 11 are connected. Then, when the state shown in FIG. 2D is reached via the state shown in FIG. 2C, both terminal groups are completely connected.

On the other hand, as shown in FIG. 1, a moderating projection 24 for holding the arm 15 at a completely connected position is provided on the left and right side surfaces near the rear of the cover 17, and is provided below the moderating projection 24. The region (region on the insertion-side connector housing 13 side) is formed flat. The moderating protrusion 24 has a triangular pyramid shape in which the amount of protrusion increases as it goes downward and tapers toward the tip. When the arm 15 is rotated from the state shown in FIG. The contact portion 16a of the short bar 16 provided on the arm 15 climbs over from above to below while elastically expanding.
5 is held at the lock position shown in FIG. In this state, two detection terminals 2 to be described later are used.
6 is short-circuited by the short bar 16, and based on this, the connection detection state of the connector can be detected by a connection detection circuit (not shown).

Further, a portion of the cover 17 near the rear end of the upper surface is
A protection ridge 25 of the book protrudes. This prevents the wires and the like from being caught on the arm 15 by being located behind the arm 15 at the lock position, and extends in the same direction as the direction in which the wires of the connector are led out, and also functions as a reinforcing rib of the cover 17. .

Now, in order to detect that the arm 15 is in the locked position, a pair of detection terminals 26 are attached to the cover 17, and the attachment structure will be described in detail below.
Near the rear ends of the right and left sides of the cover 17, thick portions 27 bulging in steps are respectively formed, and the detection terminals 26 and the electric wires 40 connected to the detection terminals 26 are formed on the upper surfaces thereof.
The storage recesses 28 each have a shape capable of storing a part of the storage recesses. The storage recess 28 extends in the front-rear direction, and has a leading end open to a flat area immediately below the moderation protrusion 24 of the cover 17.

A lid 30 is integrally formed on each of the thick portions 27 through two self-hinge portions 29, and the cover 30 is bent by bending the self-hinge portion 29. Can be put on the storage recessed portion 28. A sub-storage recess 31 having a shape capable of housing the detection terminal 26 is also formed on the side of the lid 30 that is mated with the storage recess 28 (the upper surface in the state of FIG. 5). Storage recess 28 of part 27
When the cover 30 is placed in a state in which the detection terminal 26 is stored in the sub-recess 31, a part of the detection terminal 26 is also stored in the sub storage recess 31. The cover 30
An engagement protrusion 32 is formed on the lid 30 in order to maintain a state in which the cover is placed on the upper surface of the thick portion 27.

Next, a procedure for attaching the detection terminal 26 to the cover 17 in the above configuration will be described. First, the detection terminal 26 to which the electric wire 40 is attached is picked up by a finger, and is inserted into the storage recess 28 of the thick portion 27 from the tip. At this time, the distal end of the storage recess 28 is
4 is open so as to be continuous with the flat area below
As shown in (1), the tip of the detection terminal 26 can be inserted into the flat area so as to project obliquely. Then, as shown by an arrow in FIG.
6 is in contact with the lower surface of the moderating projection 24, and the detection terminal 26 rotates counterclockwise in the drawing around the distal end of the storage recess 28, so that the rear half of the terminal 26 has a thick portion 27. , And is stored here. In this state, the tip of the detection terminal 26 comes into contact with the lower surface of the moderating projection 24 and the electric wire 4
Since the resin coating of No. 0 is press-fitted while being compressed, the detection terminal 26 is temporarily locked in the storage recess 28, and the detection terminal 26 does not fall even if the finger is released therefrom. Then, the cover 30 is pinched and the self-hinge portion 29 is bent, the cover 30 is put on the upper surface of the storage recess 28, and the engaging projection 32 is pressed so as to engage with a predetermined engaging portion. Thereby, the cover 3 is held in a state where a part of the detection terminal 26 is housed in the sub housing recess 31 of the cover 30.
0 is fixed.

In this state, as shown in FIG. 7, the detection terminal 26 is housed in the space formed by the housing recess 28 and the sub-housing recess 31, and in particular, the retaining protrusion 26a protruding from the detection terminal 26. And the storage recesses 28 and 31
By engaging with the depressions 28a, 31a formed in succession to the above, a reliable retaining state is achieved (see FIG. 5).

When the detection terminal 26 is attached in this way, to remove it for repair or inspection, for example, the cover 30 is first grasped with fingers and raised. Then, the engagement protrusion 32 of the lid 30 and the engagement recess 33
And the self-hinge part 29 is bent to cover 3
0 can be released. As a result, the detection terminal 26 is in an exposed state. For example, if the electric wire 40 is picked up and raised in the direction in which the detection terminal 26 is taken out,
The detection terminal 26 can be easily taken out. Even if the detection terminal 26 is taken out in this manner, the detection terminal 26 will not be damaged at all. Therefore, if the work is performed again according to the above-described mounting procedure, the detection terminal 26 can be easily mounted.

As described above, according to the configuration of the present embodiment, when the detection terminal 26 is attached to the cover 17, the detection terminal 26 is inserted into the storage recess 28 using the moderating projection 24.
Can be in a temporarily locked state. For this reason, the finger can be separated from the detection terminal 26 and the electric wire 40, and the assembling work becomes extremely simple. In addition, once the detection terminal 26 is removed, the lid 30 may simply be opened, and the detection terminal 26 is not damaged. Will be able to

In the present embodiment, two protection ridges 25 are provided near the rear end of the upper surface of the cover 17 so that the protection ridge 25 is located immediately behind the arm 15 as shown in FIG. Accordingly, it is possible to prevent the electric wires and the like from being caught on the arm 15 at the lock position. If this protection ridge 25 is not provided, for example, when this connector device is incorporated in a vehicle, the arm 1
When the wiring harness is routed after the connector 5 is set to the lock position and the connection of the connector is completed, there is a possibility that a part of the electric wire is hooked on the arm 15 and the lock by the arm 15 is released. is there. Further, for example, when the electric wire of the wire harness is pulled after the connection of the connector device, a force is applied to the rear end of the cover 17 from the electric wire so as to turn the cover from below, and the cover 1
7 may be damaged. On the other hand, since the above-mentioned protection projection 25 is formed at the rear end of the cover 17 so as to extend in the same direction as the direction in which the electric wire is led out, this not only functions as a hook preventing rib for the electric wire but also ,
In the present embodiment, the cover 17 also functions as a reinforcing rib, and damage to the cover 17 can be effectively prevented.

The present invention is not limited to the embodiment described above and shown in the drawings, but can be implemented with various modifications without departing from the scope of the invention.
