CROSS REFERENCE TO RELATED APPLICATIONS
This application is based on and claims priority under 35 U.S.C. ยง 119 to Japanese Patent Application No. JP2017-130996 filed Jul. 4, 2017, the contents of which are incorporated herein in their entirety by reference.
BACKGROUND OF THE INVENTION
This invention relates to a connector mateable with and removable from a mating connector by rotation of a lever.
Referring to FIGS. 31 and 32, JP-A 2008-204718 (Patent Document 1) discloses a connector 900 comprising a housing 910 and a lever 920. The housing 910 is provided with a lever accommodating portion 912 and a bearing 914, or a pivot 914. The lever accommodating portion 912 partially accommodates the lever 920. The pivot 914 is positioned inside the lever accommodating portion 912. The lever 920 is supported by the pivot 914 so as to be rotatable around the pivot 914. The connector 900 is mateable with and removable from a mating connector 950 along an up-down direction, or along a Z-direction, by operation of the lever 920.
SUMMARY OF THE INVENTION
In an assembly process of a connector having a lever similar to the connector 900 of Patent Document 1, the lever is pushed into a lever accommodating portion while an outer wall of a housing is pushed outward, so that the lever is attached into the housing. Accordingly, in order to easily attach the lever into the housing, it is preferable that the outer wall of the housing is deformable. However, because the lever is easily detached from the housing, it is unfavorable that the outer wall of the housing is excessively deformable after the lever is attached into the housing.
It is therefore an object of the present invention to provide a connector having a structure which enables a lever to be easily attached into a housing in an assembly process of the connector and which prevents the lever from being easily detached from the housing after the attachment of the lever into the housing.
One aspect of the present invention provides a connector comprising a housing and a lever. The connector is mateable with and removable from a mating connector along a first direction by operation of the lever. The housing has an inner portion, an outer portion, at least one coupling portion, a pivot, a first portion and a second portion. The outer portion is provided with at least one outer coupled portion. In a second direction perpendicular to the first direction, the outer portion is positioned away from the inner portion while being positioned outward beyond the inner portion. The housing has a lever accommodating portion between the outer portion and the inner portion in the second direction. The lever accommodating portion partially accommodates the lever. The pivot is positioned inside the lever accommodating portion. The pivot supports the lever so that the lever is rotatable. The inner portion is provided with at least one inner coupled portion. In the second direction, each of the first portion and the second portion is positioned away from the outer portion while being positioned inward beyond the outer portion. The at least one coupling portion couples the at least one outer coupled portion and the at least one inner coupled portion with each other. The at least one coupling portion has a bridge portion which is elastically deformable. In the second direction, the bridge portion is positioned away from the outer portion while being positioned inward beyond the outer portion. The bridge portion is sandwiched between the first portion and the second portion in a plane perpendicular to the second direction. The first portion is a through hole.
In the connector of the present invention, the inner portion and the outer portion are coupled by the coupling portion. Additionally, in the second direction, each of the bridge portion, the first portion and the second portion is positioned away from the outer portion while being positioned inward beyond the outer portion. Furthermore, the bridge portion of the coupling portion is sandwiched between the first portion and the second portion in the plane perpendicular to the second direction. Accordingly, the outer portion is allowed to be deformed outward in the second direction by utilizing deformation of the bridge portion, while the outer portion is prevented from being excessively deformed. Thus, the lever is easily attached into the housing in an assembly process of the connector, while the lever is prevented from being easily detached from the housing after being attached into the housing.

As shown in FIGS. 1 to 4, the lever 500 of the present embodiment is attached to the housing 150. A specific method of attaching the lever 500 to the housing 150 will be described later.
As shown in FIGS. 24 and 25, the lever 500 of the present embodiment has an arm 540 and two pinion portions 505. In the lever 500 shown in FIG. 24, the arm 540 has a substantially U-shape when viewed along the up-down direction, and the pinion portions 505 are provided on front ends, respectively, of the arm 540.
As shown in FIGS. 24 and 25, each of the pinion portions 505 of the present embodiment has an outer circumference portion 530, a bearing (bearing hole, pivot receiving portion) 510, a pivot guide portion 520 and teeth 535.
As shown in FIGS. 24 and 25, the outer circumference portion 530 of the present embodiment defines an outer circumference of the pinion portion 505 in a direction perpendicular to the right-left direction.
As shown in FIGS. 24 and 25, the bearing 510 of the present embodiment is recessed in the right-left direction, or in the second direction. More specifically, the bearing 510 of the present embodiment has a center axis parallel to the right-left direction and is recessed outward in the right-left direction. The center axes of the two bearings 510 of the pinion portions 505 are coincident with each other. The bearing 510 is positioned away from the outer circumference portion 530 in the direction perpendicular to the right-left direction, or to the second direction. The bearing 510 receives the pivot 210 of the first housing 200 of the housing 150. More specifically, the bearings 510 of the pinion portions 505 of the lever 500 correspond to the pivots 210, respectively, of the first housing 200 of the housing 150, and each of the bearings 510 receives the corresponding pivot 210.

The pivot guide portion 520 has a guide surface 522 which intersects with the plane perpendicular to the right-left direction, or a plane perpendicular to the second direction. More specifically, the guide surface 522 of the pivot guide portion 520 illustrated in FIG. 24 is sloped upward and inward in the right-left direction.
Referring to FIGS. 4, 6 and 14 to 16, each of the sliders 620 of the present embodiment has a plate-like shape which extends in the front-rear direction and which is perpendicular to the right-left direction. Each of the sliders 620 has a rack 621 and three cam ditches (not shown). The sliders 620 are accommodated in the slider accommodating portions 420, respectively, of the second housing 300. The sliders 620 correspond to the pinion portions 505, respectively, of the lever 500. The rack 621 of each of the sliders 620 is meshed with the teeth 535 of the corresponding pinion portion 505 of the lever 500 to convert a rotational movement of the lever 500 into a movement of each of the sliders 620 in the front-rear direction. The cam ditches of the slider 620 are configured to receive three of the cam protrusions 710 of the mating connector 700 when the connector 100 and the mating connector 700 are mated with each other.
As shown in FIGS. 1 to 3, the cover 650 of the present embodiment has an opening 652 at its rear end. The cover 650 is positioned upward of the housing 150 in the up-down direction. The cover 650 is attached to the housing 150.
A method of attaching the lever 500 to the housing 150 is described below.
Referring to FIGS. 24 to 29, first, the lever 500 is positioned relative to the housing 150 so that each of the bearings 510 of the pinion portions 505 of the lever 500 and the corresponding pivot 210 of the first housing 200 of the housing 150 are arranged on a single axis parallel to the up-down direction. Meanwhile, the lever 500 and the housing 150 are in a state shown in each of FIGS. 26 and 27. After that, when the lever 500 is moved downward relative to the housing 150, the lever 500 and the housing 1500 are in a state shown in each of FIGS. 28 and 29.
Meanwhile, as shown in FIG. 29, the guide surface 522 of the pivot guide portion 520 of each of the pinion portions 505 of the lever 500 is brought into contact with the corresponding pivot 210 of the first housing 200 of the housing 150 in the up-down direction.
When the lever 500 is further moved downward under this state, each of the pinion portions 505 of the lever 500 is pushed outward in the right-left direction by the corresponding pivot 210. Meanwhile, the arm 540 of the lever 500 is deformed so as to have an increased distance between the front ends of the arm 540 in the right-left direction. Also meanwhile, the outer main 352 of each of the outer portions 340 of the second housing 300 of the housing 150 is deformed outward in the right-left direction. As the outer main 352 of each of the outer portions 340 is deformed outward in the right-left direction, an inner end of each of the outer side portions 350 in the front-rear direction is moved outward in the right-left direction, so that the lower end of each of the bridge portions 364 is moved outward in the right-left direction.
As described above, the bridge portion 364 of the coupling portion 360 of the second housing 300 is sandwiched between the first portion 370 and the second portion 380 in the plane perpendicular to the right-left direction, or to the second direction. Accordingly, the bridge portion 364 of the present embodiment is more elastically deformable outward in the right-left direction in comparison with an assumption where the bridge portion 364 be rigidly coupled with the second housing 300 in the plane perpendicular to the right-left direction. Thus, the lever 500 is easily inserted into the housing 150. Especially, in a case where the second portion 380 is the through hole, the bridge portion 364 is still more elastically deformable outward in the right-left direction in comparison with an assumption where a thickness dimension of the second portion 380 be smaller than the thickness dimension of the bridge portion 364 in the right-left direction. Thus, the lever 500 is still easily inserted into the housing 150.
After that, when the lever 500 is still further moved downward so that a lower end of the bearing 510 of each of the pinion portions 505 of the lever 500 is positioned at a position same as a position of a lower end of the corresponding pivot 210 in the up-down direction, the bearing 510 of each of the pinion portions 505 of the lever 500 accommodates the corresponding pivot 210. Meanwhile, the arm 540 of the lever 500 restores its original shape while the outer mains 352 of the outer portions 340 of the second housing 300 of the housing 150 restore their original shapes. Specifically, the lever 500 and the housing 150 are relatively positioned as shown in FIG. 4.
As described above, the guide surface 522 of each of the pivot guide portions 520 of the lever 500 is sloped inward in the right-left direction. Specifically, in the right-left direction, a travel distance, by which each of the pinion portions 505 of the lever 500 is required to be moved when the lever 500 is tried to be removed from the housing 150 after the attachment of the lever 500 to the housing 150, is greater than a travel distance by which each of the pinion portions 505 of the lever 500 is required to be moved when the lever 500 begins to be inserted into the housing 150. Accordingly, in the connector 100 of the present embodiment, the lever 500 is hardly removed from the housing 150 after the lever 500 is attached to the housing 150.
Referring to FIGS. 1, 4, 9 and 29, since the lever 500 is attached to the housing 150 as described above, the pivots 210 support the lever 500 so that the lever 500 is rotatable. More specifically, the lever 500 is rotatable from a second position to a third portion through a first position. Similarly, the lever 500 is rotatable from the third position to the second position through the first position.
The structure of the housing 150 is not limited thereto. For example, the housing 150 can be modified as described below.
Referring to FIG. 30, a housing 150A according to a modification of the present invention is made of insulator. Specifically, the housing 150A of the present embodiment has a first housing 200 and a second housing 300A. The first housing 200 of the present modification is similar to the first housing 200 of the aforementioned embodiment. Accordingly, detail explanation thereabout is omitted.
Referring to FIG. 30, the second housing 300A of the present modification has a top plate portion 310, two inner portions 320, two outer portions 340A, four coupling portions 360, two first portions 370, four second portions 380, four connecting portions 390, four linking portions 395, side walls 430, 440, two lever accommodating portions 400 and two slider accommodating portions 420. The components of the second housing 300A except for the outer portions 340A are similar to the components of the second housing 300 of the aforementioned embodiment. Accordingly, detail explanation thereabout is omitted.
As shown in FIG. 30, each of the outer portions 340A of the present modification has two outer side portions 350A and an outer main 352A. In addition, each of the outer portions 340A of the present modification is provided with a ditch 344. Except that the outer portion 340A of the present modification is provided with the ditch 344, the outer portion 340A of the present modification has a structure similar to that of the outer portion 340 of the aforementioned embodiment. Accordingly, detail explanation about components of the outer portion 340A other than the ditch 344 is omitted.
As shown in FIG. 30, the ditch 344 of the present modification extends so as to intersect with the up-down direction, or the first direction. More specifically, the ditch 344 extends in the front-rear direction and traverses the outer main 352A to reach each of the outer side portions 350A. The ditch 344 pierces the outer portion 340A in the right-left direction, or in the second direction. Referring to FIGS. 2, 23 and 30, the ditch 344 is positioned between a mating end 152 and a pivot 210 in the up-down direction, or in the first direction. More specifically, the ditch 344 is positioned between an upper end and a lower end of each of the outer side portions 350A in the up-down direction.
Referring to FIG. 30, when a lever 500 is attached to the housing 150A in an assembly process of a connector (not shown) into which the housing 150A of the present modification is assembled, an upper part of the outer portion 340A which is above the ditch 344 can be more deformed outward in the right-left direction than that of the housing 150 of the aforementioned embodiment. Accordingly, it is easily to attach the lever 500 to the housing 150A.
Although the specific explanation about the present invention is made above referring to the embodiments, the present invention is not limited thereto and is susceptible to various modifications and alternative forms.
Although the outer portion 340, 340A of the present embodiments has the four outer coupled portions 342, the present invention is not limited thereto. Specifically, it is sufficient that the outer portion 340, 340A is provided with at least one outer coupled portion 342.
