[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to the lever principle of lever.
More particularly, the present invention relates to a lever type connector in which a connector housing is connected side by side and integrally.

[0002]

2. Description of the Related Art In recent years, there has been provided a multiple connector type of a lever type connector in which a plurality of connector housings are arranged side by side and integrated. For example, a double connector is
Specifically, the configuration was as shown in FIG. here,
The male connector housings 1 are arranged in parallel on the left and right and are integrally connected. Each male connector housing 1 has a lever support shaft 2 protruding from both left and right side surfaces thereof. A gate-shaped lever 3 having a cam groove is mounted on the lever support shaft 2 so as to be rotatable so as to straddle the connector housing 1, and when the lever 3 is rotated, the lever 3 is supported by the lever. Outer walls 4 are provided integrally with the male connector housing 1 on both sides of the lever 3 so as to prevent the lever 2 from coming off the shaft 2.

[0003]

The lever 3 is mounted on the connector housing 1 by fitting the bearing hole 3a of the lever 3 into the lever support shaft 2 of the connector housing 1 in the process of assembling the connector. When the lever 3 is fitted to the lever support shaft 2, the leg portion of the lever 3 expands by the protrusion dimension of the lever support shaft 2, so that the outer wall portion 4 is also pushed outward by being pushed by this.

However, in the conventional configuration, since the outer wall portions 4 are provided on both left and right sides of each male connector housing 1, the two outer wall portions 4 allow the bending deformation between the connector housings 1. There is a problem in that the connector housings 1 are arranged side by side with a gap therebetween, and the dimension in the direction in which the two connector housings 1 are arranged generally becomes large.

The present invention has been made in view of the above circumstances, and aims to reduce the size of a lever-type connector in which connector housings are connected side by side in the direction in which the connector housings are arranged.

[0006]

In order to achieve the above object, a lever-type connector according to the present invention has a connector housing having levers connected side by side in a horizontal direction, and inserted between adjacent levers after being mounted. The present invention is characterized in that the provided regulating plate is provided (the invention of claim 1). in this case,
The regulating plate may be removable from between the levers (the invention of claim 2).

[0007]

The procedure for assembling the lever-type connector according to the first aspect is as follows. In order to mount the lever on the connector housing, the bearing hole is fitted to the lever support shaft while slightly extending the lower end of the lever so as to straddle the connector housing. After the levers have been mounted on all the connector housings in this way, a regulating plate is inserted between adjacent levers to prevent the levers from coming off the lever support shaft.

As described above, since the regulating plate for regulating the detachment of the lever after the lever is mounted is provided, there is no need to provide an outer wall portion between the adjacent connector housings as in the prior art, and the deflection of the lever is allowed. It is only necessary to have a gap. Therefore, the two connector housings can be arranged closer to each other by the thickness of the two outer wall portions than in the conventional case.

According to the second aspect of the invention, for example, when a part of the lever is damaged and only the lever needs to be replaced, the regulating plate is removed and the lower end of the lever is slightly widened while the lever supporting shaft is extended. Can be removed from.

[0010]

As described above, according to the lever-type connector of the first aspect, since the release of the lever can be restricted by the restricting plate, the outer wall portion between the connector housings, which is conventionally required, is omitted. This has the effect of reducing the size in the arrangement direction.

Further, according to the lever-type connector of the second aspect, the restriction plate for restricting disengagement of the lever is made detachable, so that the operation such as replacement of the lever can be easily performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the lever-type connector of this embodiment has two male connector housings 1.
A male connector housing body 12 is provided, in which the right and left 1, 11 are arranged side by side and integrated, and is configured as a double type so that each can be connected to the female connector 13.

The female connector 13 has a well-known configuration including a rectangular parallelepiped female connector housing 14 and a number of female terminals disposed in the female connector housing 14.
A cover 15 is integrally attached to an upper portion of the female connector housing 14, and two cam projections 16 are provided coaxially at substantially the center of the left and right side walls.

On the other hand, the male connector housing body 12 has a configuration in which the two male connector housings 11 are connected side by side via the connecting portion 17 as described above, and each connector housing 11 can accommodate the female connector housing 14. A rectangular female connector storage chamber 18 is provided. A large number of male terminal storage chambers 19 are provided below the female connector storage chamber 18, and the tips of male terminals (not shown) arranged in the male terminal storage chamber 19 are arranged in parallel in the female connector storage chamber 18. It protrudes in a state. The connecting portion 17 is provided at each of the connector housings 11 at the back (lower portion in FIG. 2) and the bottom portion (lower portion in FIG. 3) of the male connector housing body 12.
And the upper part and the front part are open in a groove shape.

Lever support shafts 20, 20 are coaxially protruded from the left and right side walls of each male connector housing 11, and a two-leg type lever 21 is mounted on each of the lever support shafts 20, as shown in FIG. It is provided so as to straddle the male connector housing 11. This lever 21 has its legs 2
A bearing hole 22 formed in 1 a is fitted to and attached to the lever support shaft 20, and is rotatable with respect to the male connector housing 11. Each leg 21a
Has an arc-shaped cam groove 23 centered on the bearing hole 22 and an insertion groove 24 formed on the inner surface from the right edge of the leg to the right end of the cam groove 23. A cam projection 16 provided on the connector housing 14 enters the cam groove 23 through the insertion groove 24 and engages with the cam groove 23.

Outer walls 25 are integrally provided on the left and right side walls of the male connector housing body 12, respectively.
The legs 21 a of each lever 21 are sandwiched between the left and right side walls of the male connector housing 11. Therefore, the gap between the outer wall 25 and the side wall of the male connector housing 11 is set to be substantially equal to or slightly larger than the thickness of the leg 21a of the lever 21.

On the other hand, as shown in FIG. 3, the outer wall portion 25 as described above is provided on the right side wall of the left male connector housing 11 and the left side wall portion of the right male connector housing 11. It is not provided, and the side walls are in a state of facing each other. When the lever 21 is mounted on each connector housing 11, the distance X between the bearing housing 22 and the lever support shaft 2 is set between the levers 21.
The value is set such that a gap having a dimension larger than the margin for zero is generated. That is, the value is set to satisfy the following expression.

X = 2y + x0 x0> y0 where: X: distance between opposed side walls of each connector housing 11 y: thickness of leg 21a of lever 21 x0: each lever mounted on each connector housing 11 A gap dimension y0 between the bearings 21 is an allowance between the bearing hole 22 of the lever 21 and the lever support shaft 20.

The male connector housing body 12
A holding groove 12a is continuously formed in a portion of the connecting portion 17 corresponding to the gap between the levers 21, and the regulating plate 26 is detachable so as to fill the gap between the levers 21 here. It is press-fitted. The thickness of the regulating plate 26 is set slightly smaller than the gap x0 between the levers 21 mounted on the connector housings 11, and when the leg 21a of the lever 21 is bent, the thickness of the regulating plate 26 is reduced. Therefore, the amount of deflection of the lever 21 can be suppressed to a value smaller than the margin y0 between the bearing hole 22 and the lever support shaft 20.

Next, the operation of mounting the lever 21 on the male connector housing 11 will be described. First, one of the two levers 21 is attached to, for example, the right male connector housing 11. To do this, hold the lever 21 in hand, straddle the connector housing 11 from above, place its legs 21 a on the side wall of the male connector housing 11, and press the lower end against the lever support shaft 20. When the lever 21 is strongly pushed down from this state, the legs 21a, 21a of the lever 21 are bent and deformed so as to be pushed and spread by the lever support shafts 20, 20. If the lever 21 is continuously pressed downward in this state, the lever support shaft 20 is fitted into the bearing hole 22 and the lever 21 is rotatably attached to the male connector housing 11. In the process of assembling the right lever 21 described above, the left leg 21 a of the lever 21 can be flexed and deformed freely, but the right leg 21 a hits the inner surface of the outer wall 25 of the connector housing 11. Attached while flexing and deforming outward.

Next, the remaining lever 21 is mounted on the left connector housing 11 in the same manner as described above. After installation,
When the regulating plate 26 is attached to the holding groove 12a provided in the connecting portion 17 of the male connector housing body 12, the lever 2
1 is completed. When the second lever 21 is mounted, the right leg 21a bends outward and deforms. However, as described above, the gap dimension x0 between the levers 21 mounted on each connector housing 11 is determined by the lever. Since the engagement margin y0 between the bearing hole 22 of the lever 21 and the lever support shaft 20 is set to be larger, the necessary bending deformation of the lever 21 is allowed, and the lever support shaft 20 fits into the bearing hole 22.

In the state where the regulating plate 26 is attached to the male connector housing body 12 as described above, if the lever 21 is rotated, the leg 21a is
Leg 21a is restricted by the restricting plate 2
Since further deformation is prevented by hitting 6, the bending deformation of the lever 21 to the extent that it comes off the lever support shaft 20 is reliably prevented, and the lever 21 is prevented from falling off.

In order to remove the lever 21 for replacement or the like, for example, the control plate 26 is pulled out from the male connector housing body 12 and then the leg 21a of the lever 21 is removed.
May be bent to extract the lever support shaft 20 from the bearing hole 22.

As described above, in this embodiment, after the lever 21 is mounted, the restriction plate 26 is inserted between the male connector housings 11 to restrict the lever 21 from coming off. There is no need to provide outer wall portions on both left and right sides of the eleventh embodiment. Accordingly, the size of the male connector housing body 12 in the direction in which the male connector housing body 12 is arranged can be reduced and the size can be reduced, as compared with the conventional case, because the two outer wall portions can be omitted. Further, a regulating plate 2 for regulating the lever 21 from coming off.
6 is detachable, so that the lever 2
1 can be exchanged. Note that the regulating plate 26 is not limited to be provided in a removable manner, and may be attached in a non-removable manner by, for example, press-fitting or bonding, and the intended operation and effect of the present invention can be obtained in this case as well.

In the above embodiment, the regulating plate 26 is held by engaging with the holding groove 12a. However, the rotation of the lever 21 is simply performed between the male connector housings 11 without providing the holding groove 12a. It may just be inserted into the press fit to the extent allowable. Of course, such a configuration is included in the concept of “inserting between adjacent one sides of the lever” in the claims of the present application.

In the above embodiment, the cam projection 16 is provided on the female connector housing 14 of the female connector 13.
However, the present invention is not limited to this, and may be configured to protrude from the cover 15 of the female connector 13, and the configuration is also included in the concept of “cam protrusion protruding from the connector housing side” according to the present invention. Further, it is needless to say that the male and female terminals may be arranged in a reverse relationship to the above embodiment.
