Description

[Technical field]

[0001] The present disclosure relates to a connector assembly. [Background technology]

[0002] Conventionally, there is a connector assembly that includes a first connector that is fixed to a base member such as an equipment case or a vehicle body panel, and a second connector that can be connected to the first connector. In addition, there is a connector that includes a cylindrical elastic cover (see, for example, Patent Document 1). The elastic cover is made of an elastic material such as rubber, and covers the housing of the connector to improve the dust resistance of the connector. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-44303 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, some second connectors connectable to a first connector have an operating part such as a lever. The operating part is configured to be able to move the second housing of the second connector relative to the first housing of the first connector in the mating direction when operated. In such a second connector, the second housing can be mated with the first housing by operating the operating part. However, in such a second connector, the operating part cannot be operated in a state where a cylindrical elastic cover is attached to the second housing. Therefore, for example, it is necessary to attach the elastic cover after assembling the second housing to the first housing. Therefore, there is a problem of poor assembly.

[0005] An object of the present disclosure is to provide a connector assembly that is capable of achieving both high dust resistance and high ease of assembly. [Means for solving the problem]

[0006] The connector assembly disclosed herein is a connector assembly including a first connector fixed to a base member and a second connector connectable to the first connector, wherein the first connector has a first housing, and the second connector has a second housing that can be mated with the first housing by being moved relative to the first housing in a mating direction, an operating unit that is operable relative to the second housing and moves the second housing relative to the first housing in the mating direction by being operated from a non-mating position to a mating position, and a cylindrical elastic cover that covers the second housing and the operating unit, wherein the elastic cover has a cover main body having an operating opening that enables operation of the operating unit from the outside, and a lid that can close the operating opening. Effect of the Invention

[0007] The connector assembly of the present disclosure can achieve both high dust resistance and high ease of assembly. [Brief description of the drawings]

[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The connector assembly of the present disclosure comprises: [1] A connector assembly comprising a first connector fixed to a base member and a second connector connectable to the first connector, wherein the first connector has a first housing, and the second connector has a second housing that can be mated with the first housing by being moved relative to the first housing in a mating direction, an operating unit that is operably provided with respect to the second housing and moves the second housing relative to the first housing in the mating direction by being operated from a non-mating position to a mating position, and a cylindrical elastic cover that covers the second housing and the operating unit, wherein the elastic cover has a cover main body having an operating opening that enables operation of the operating unit from the outside, and a lid that can close the operating opening.

[0010] According to this configuration, the elastic cover covers the second housing and the operation unit, so that the second connector has good dust resistance. The elastic cover has a cover body having an operation port that allows the operation unit to be operated from the outside, and a lid that can close the operation port, so that, for example, the operation unit can be operated with the cover body attached to the second housing. Therefore, it is possible to achieve both high dust resistance and high ease of assembly.

[0011] [2] In the above [1], the lid may have a lid body that is pressed into the operation port to adhere to an inner surface of the operation port, and a press-in positioning portion that abuts against the second housing or the operation portion to position the lid body in a press-in direction relative to the operation port.

[0012] According to this configuration, the lid has a lid body that is press-fitted into the operation port to closely contact the inner surface of the operation port, and thus the operation port can be closed. The lid has a press-fit positioning portion that abuts against the second housing or the operation portion to position the lid body in the press-fit direction relative to the operation port, and thus the lid body can be easily and satisfactorily press-fitted into the operation port. That is, for example, in a configuration in which the lid does not have a press-fit positioning portion, there is a risk that the lid body will be inserted too far when the lid body is press-fitted into the operation port, but this risk can be avoided, and therefore the lid body can be easily and satisfactorily press-fitted into the operation port.

[0013] [3] In the above [1] or [2], the lid may have a lid body that is pressed into the operation port to adhere closely to an inner surface of the operation port, and a position shift prevention portion that abuts against the operation portion or the second housing to suppress position shifting of the elastic cover relative to the second housing in the opposite direction to the fitting direction.

[0014] According to this configuration, the lid has a lid body that is press-fitted into the operation port to closely contact the inner surface of the operation port, thereby closing the operation port. The lid has a displacement suppression part that abuts against the operation unit or the second housing to suppress displacement of the elastic cover in the direction opposite to the fitting direction relative to the second housing, thereby suppressing displacement of the elastic cover. The displacement suppression part is disposed together with the lid body after the cover body is attached to the second housing, and therefore does not get in the way when the cover body is moved relative to the second housing in the fitting direction to be attached.

[0015] [4] In any one of [1] to [3] above, the lid may be configured to be able to close the operation opening when the operation part is in the engaged position, and may be configured to be unable to close the operation opening when the operation part is in the non-engaged position.

[0016] According to this configuration, the lid is configured to be able to close the operation port when the operation unit is in the mating position, and is configured to be unable to close the operation port when the operation unit is in the non-mating position, so that incorrect assembly can be suppressed. In other words, when the lid cannot properly close the operation port, the worker can recognize that the second housing is not properly mated with the first housing. Therefore, incorrect assembly can be suppressed.

[0017] [5] In any one of the above [1] to [4], the elastic cover may have a thin hinge portion connecting the cover body and the lid. According to this configuration, the elastic cover has a thin hinge portion that connects the cover body and the lid, so that the number of parts can be reduced compared to, for example, a case in which the cover body and the lid are separate bodies.

[0018] [Details of the embodiment of the present disclosure] Specific examples of the connector assembly of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configuration may be exaggerated or simplified. In addition, the dimensional ratio of each part may differ in each drawing. In this specification, "parallel," "orthogonal," and "perfect circle" do not only mean strictly parallel, orthogonal, or perfect circle, but also include approximately parallel, orthogonal, or perfect circle within the range of the action and effect of this embodiment. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0019] (Configuration of connector assembly 11) As shown in FIG. 1, the connector assembly 11 includes a first connector 21 and a second connector 31 connectable to the first connector 21. The connector assembly 11 is provided in a vehicle. For example, the first connector 21 is fixed to an equipment case 41 serving as a base member in the vehicle. In this embodiment, the connector assembly 11 and the equipment case 41 configure a connector device C. Also, for example, there are multiple second connectors 31, and in this embodiment, the second connectors 31 are fixed to ends of four electric wires 42.

[0020] The figure also shows a first axis X, a second axis Y perpendicular to the first axis X, and a third axis Z perpendicular to the first axis X and the second axis Y. The figure also shows a fitting direction X1, which is a direction along the first axis X, and a width direction Y1, which is a direction along the second axis Y. The figure also shows an upward direction Z1 along the third axis Z, and a downward direction Z2 opposite to the upward direction Z1.

[0021] (Configuration of first connector 21) The first connector 21 has a first housing 22 and a plurality of first terminals 23 (four in this embodiment) held by the first housing 22. The first housing 22 is made of resin.

[0022] The first housing 22 has a first main body portion 22a, an engagement shaft 22b, and a flange portion 22c. The first main body portion 22a is formed in a rectangular tube shape. The first main body portion 22a holds four first terminals 23 inside. The first terminals 23 are to be electrically connected to electrical components (not shown) provided inside the device case 41. A pair of engagement shafts 22b extend outward from the first main body portion 22a along the second axis Y.

[0023] The flange portion 22c extends outward from the entire outer periphery of the first main body portion 22a in a plate shape. Fixing holes 22d are provided at four corners of the flange portion 22c. The first connector 21 is fixed to the device case 41 by bolts 43 that pass through the fixing holes 22d.

[0024] More specifically, the device case 41 has a base portion 41a protruding outward. The base portion 41a is formed in a rectangular shape larger than the flange portion 22c when viewed from the direction along the first axis X. A female screw portion (not shown) is formed at each of the four corners of a tip surface 41b of the base portion 41a. The annular side surface of the base portion 41a constitutes a contact surface 41c (described later). The first connector 21 is fixed to the device case 41 by a bolt 43 that penetrates a cylindrical collar 44 arranged inside the fixing hole 22d and is screwed into the female screw portion of the base portion 41a.

[0025] (Configuration of second connector 31) 1 and 2, the second connector 31 has a second housing 32 and a plurality of second terminals 33 (four in this embodiment) held by the second housing 32. The second connector 31 also has an operating lever 34 as an operating part, and an elastic cover 35. The second housing 32 and the operating lever 34 are made of resin. The elastic cover 35 is made of an elastic material such as rubber.

[0026] As shown in Fig. 2, the second housing 32 has a second main body portion 32a and a support shaft 32b. The second main body portion 32a is formed in a rectangular tubular shape. The second main body portion 32a is formed so as to be able to be fitted onto the outside of the first main body portion 22a (see Fig. 1). The second main body portion 32a holds four second terminals 33 inside. The second terminals 33 are connected to ends of electric wires 42.

[0027] Specifically, the electric wire 42 has a conductive core wire 42a and an insulating coating 42b that surrounds the outer periphery of the core wire 42a and has insulating properties. The second terminal 33 is electrically connected to the core wire 42a exposed at the end of the electric wire 42. The second terminal 33 is provided so as to be connectable to the first terminal 23 (see FIG. 1) in a state in which the second housing 32 is fitted into the first housing 22, more specifically, in a state in which the second main body portion 32a is fitted onto the first main body portion 22a.

[0028] The pair of support shafts 32b extend outward from the second main body portion 32a along the second axis Y (see FIG. 3). The operating lever 34 is rotatably connected to the pair of support shafts 32b and is operable.

[0029] 3, the operating lever 34 has a pair of rotating side portions 34a and a connecting portion 34b connecting the pair of rotating side portions 34a. The rotating side portion 34a has a support hole 34c. The operating lever 34 is assembled to the second housing 32 such that the connecting portion 34b is disposed in the upward direction Z1 of the second housing 32 and the support shaft 32b is inserted into the support hole 34c. As a result, the operating lever 34 is connected to the support shaft 32b so as to be rotatable from the non-engaged position (see FIGS. 1, 2, and 4) to the engaged position (see FIG. 6).

[0030] In addition, the inner surfaces of the pair of rotating side portions 34a facing each other have a guide groove 34d. The guide groove 34d is formed so that the engagement shaft 22b (see FIG. 1) of the first housing 22 can enter the guide groove 34d. The guide groove 34d extends in a curved manner so that the second housing 32 moves relative to the first housing 22 in the mating direction X1 when the operation lever 34 is operated from the non-mating position to the mating position with the engagement shaft 22b (see FIG. 1) slightly entered. That is, the operation lever 34 is configured to move the second housing 32 relative to the first housing 22 in the mating direction X1 when operated from the non-mating position to the mating position, thereby mating the second housing 32 with the first housing 22. Note that the operation lever 34 of this embodiment is set to be in a state where it protrudes more in the upward direction Z1 at the non-mating position (see FIG. 5) than at the mating position (see FIG. 7).

[0031] 1 and 2, the elastic cover 35 is formed in a cylindrical shape capable of covering the second housing 32 and the operating lever 34. The elastic cover 35 is formed so as to cover the entire second housing 32 from its end in the fitting direction X1 to its end in the opposite direction to the fitting direction X1. The elastic cover 35 is also formed so as to cover a part of the electric wire 42 leading out from the second housing 32. The elastic cover 35 is formed in a cylindrical shape so that no large gap is created between the second housing 32, the operating lever 34, and the electric wire 42.

[0032] 9, the elastic cover 35 is configured to cover the first housing 22 when the second housing 32 is fitted into the first housing 22. More specifically, the elastic cover 35 is configured to cover the entire first housing 22 exposed to the outside of the device case 41 when the second housing 32 is fitted into the first housing 22. The elastic cover 35 is configured to cover the first housing 22 as well as the bolts 43 (see FIG. 1) when the second housing 32 is fitted into the first housing 22.

[0033] As shown in Figs. 1 and 4, the elastic cover 35 has a cover body 35b having an operation port 35a that allows the operation lever 34 to be operated from the outside, and a lid 35c that can close the operation port 35a. The elastic cover 35 also has a thin hinge portion 35d that connects the cover body 35b and the lid 35c. That is, the elastic cover 35 is an integrally molded product including the cover body 35b, the lid 35c, and the hinge portion 35d. The lid 35c can be disposed at a position that can close the operation port 35a by bending the hinge portion 35d (see Fig. 9). The elastic cover 35 is attached to the second housing 32 by a part of the cover body 35b covering the second housing 32 and closely contacting the second housing 32 so as to sandwich the second housing 32.

[0034] The operation port 35a is open in the upward direction Z1 of the cover body 35b so as to expose the operation lever 34. The operation port 35a is formed in a rectangular shape. The inner surface of the operation port 35a has a plurality of protrusions 35e protruding from the entire circumferential direction.

[0035] The lid 35c has a lid body 35f that is press-fitted into the operation opening 35a and adheres closely to the inner surface of the operation opening 35a. The lid body 35f is formed in a rectangular plate shape corresponding to the operation opening 35a. The outer surface of the lid body 35f that faces the inner surface of the operation opening 35a when pressed into the operation opening 35a has a plurality of recesses 35g recessed from the entire circumferential direction. This allows the lid body 35f to be press-fitted into the operation opening 35a so that the protrusions 35e fit into the recesses 35g.

[0036] 9, the lid 35c has a press-fit positioning portion 35h that positions the lid body 35f relative to the operation opening 35a in the press-fit direction by abutting against the second housing 32. The lid 35c also has a position shift suppression portion 35j that suppresses position shift of the elastic cover 35 relative to the second housing 32 in the opposite direction to the fitting direction X1 by abutting against the operation lever 34.

[0037] Specifically, as shown in Fig. 1, the lid 35c has a tube portion 35k protruding in a rectangular tube shape from the lid main body 35f. A tip of the tube portion 35k abuts against the second housing 32 to form a press-fit positioning portion 35h that positions the lid main body 35f relative to the operation opening 35a in the press-fit direction, as shown in Fig. 9. A part of a side of the tube portion 35k abuts against the operation lever 34 arranged at the fitting position to form a position shift suppression portion 35j that suppresses position shift of the elastic cover 35 relative to the second housing 32 in the opposite direction to the fitting direction X1, as shown in Fig. 9.

[0038] The cover 35c is configured to be able to close the operation opening 35a when the operation lever 34 is in the mating position (see Figs. 7 and 9), and is configured to be unable to close the operation opening 35a when the operation lever 34 is in the non-mating position (see Fig. 5). That is, the operation lever 34 is in a state where it protrudes farther in the upward direction Z1 than in the mating position (see Fig. 7) and protrudes to the outside from the operation opening 35a at the non-mating position (see Fig. 5), and therefore the cover 35c is configured to be unable to close the operation opening 35a.

[0039] 7, the elastic cover 35 has a contact portion 35m that contacts the contact surface 41c of the device case 41 in a direction intersecting the fitting direction X1 on the entire circumference of the inner circumferential surface at the tip end in the fitting direction X1 when the second housing 32 is fitted into the first housing 22. When the second housing 32 is fitted into the first housing 22, the contact portion 35m is disposed so as to surround the entire circumference of the contact surface 41c and contacts the contact surface 41c in a direction perpendicular to the fitting direction X1, specifically, in a direction along the second axis Y and a direction along the third axis Z.

[0040] 2 and 5, the contact portion 35m has a contact protrusion 35n that protrudes to locally come into strong contact with the contact surface 41c. A plurality of the contact protrusions 35n are arranged in parallel in the fitting direction X1. When the second housing 32 is fitted into the first housing 22, the contact protrusions 35n come into localized contact with the contact surface 41c with strong pressure in a direction perpendicular to the fitting direction X1 while being crushed.

[0041] 7, the elastic cover 35 has a tip contact portion 35p at a tip in the fitting direction X1 that comes into close contact with the abutment surface 41d of the device case 41 in the fitting direction X1 when the second housing 32 is fitted into the first housing 22. The tip contact portion 35p comes into close contact with the abutment surface 41d in the fitting direction X1 when the second housing 32 is fitted into the first housing 22.

[0042] Next, the operation of the connector assembly 11 configured as above will be described. As shown in Figures 4 and 5, when connecting the second connector 31 to the first connector 21, the worker first grasps the second connector 31 and moves it relative to the first connector 21 in the mating direction X1 to bring it into a pre-mating state.

[0043] In the pre-fitting state, the operating lever 34 is disposed in a non-fitting position. In the pre-fitting state, the engaging shaft 22b (see FIG. 1) is slightly inserted into the guide groove 34d (see FIG. 3). In the pre-fitting state, the cover 35c does not close the operating opening 35a.

[0044] 6 and 7, the operator operates the operating lever 34 from the non-mating position (see FIGS. 4 and 5) to the mating position to move the second housing 32 relative to the first housing 22 in the mating direction X1. As a result, the second housing 32 is mated with the first housing 22. As a result, the second connector 31 is connected to the first connector 21, and the second terminal 33 (see FIG. 1) is connected to the first terminal 23.

[0045] 7, the contact portion 35m of the elastic cover 35 comes into contact with the contact surface 41c of the device case 41 in a direction perpendicular to the fitting direction X1. The tip contact portion 35p of the elastic cover 35 comes into contact with the abutment surface 41d of the device case 41 in the fitting direction X1.

[0046] 8 and 9, the worker presses the lid body 35f into the operation opening 35a to close the operation opening 35a with the lid 35c. As a result, the first housing 22, the second housing 32, the operation lever 34, the bolt 43, etc. are covered with the elastic cover 35. In this manner, the connection work between the first connector 21 and the second connector 31 is completed.

[0047] Next, the effects of the above embodiment will be described below. (1) The elastic cover 35 covers the second housing 32 and the operating lever 34, improving the dust resistance of the second connector 31. The elastic cover 35 has a cover body 35b having an operating opening 35a that allows the operating lever 34 to be operated from the outside, and a lid 35c that can close the operating opening 35a. Therefore, for example, the operating lever 34 can be operated with the cover body 35b attached to the second housing 32. Therefore, it is possible to achieve both high dust resistance and high ease of assembly.

[0048] (2) The lid 35c has the lid body 35f that is press-fitted into the operation opening 35a and adheres closely to the inner surface of the operation opening 35a, so that the operation opening 35a can be closed. The lid 35c has the press-fit positioning portion 35h that abuts against the second housing 32 to position the lid body 35f in the press-fit direction relative to the operation opening 35a, so that the lid body 35f can be easily and satisfactorily press-fitted into the operation opening 35a. That is, for example, in a configuration in which the lid 35c does not have the press-fit positioning portion 35h, there is a risk that the lid body 35f will be inserted too far if too much force is applied in the downward direction Z2 when the lid body 35f is press-fitted into the operation opening 35a, but this risk can be avoided. Therefore, the lid body 35f can be easily and satisfactorily press-fitted into the operation opening 35a.

[0049] (3) The lid 35c has the displacement suppression portion 35j that suppresses displacement of the elastic cover 35 relative to the second housing 32 in the opposite direction of the fitting direction X1 by abutting against the operating lever 34, thereby suppressing displacement of the elastic cover 35. In addition, the displacement suppression portion 35j is disposed together with the lid main body 35f after the cover main body 35b is attached to the second housing 32, and therefore does not get in the way when the cover main body 35b is moved relatively to the second housing 32 in the fitting direction X1 to be attached.

[0050] (4) The cover 35c is configured to be able to close the operation opening 35a when the operation lever 34 is in the mated position, and is configured to be unable to close the operation opening 35a when the operation lever 34 is in the non-mated position, so that incorrect assembly can be suppressed. In other words, when the cover 35c cannot properly close the operation opening 35a, the worker can recognize that the second housing 32 is not properly mated with the first housing 22. Therefore, incorrect assembly can be suppressed.

[0051] (5) Elastic cover 35 has thin hinge portion 35d that connects cover body 35b and lid 35c. This allows the number of parts to be reduced compared to a case in which cover body 35b and lid 35c are separate bodies.

[0052] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. In the above embodiment, the lid 35c has the press-fit positioning portion 35h that abuts against the second housing 32 to position the lid body 35f relative to the operation opening 35a in the press-fit direction, but this is not limited thereto, and the press-fit positioning portion 35h may not be included. Also, the press-fit positioning portion 35h may be configured to abut against the operation lever 34 to position the lid body 35f relative to the operation opening 35a in the press-fit direction.

[0053] In the above embodiment, the cover 35c has the misalignment suppression portion 35j that suppresses misalignment of the elastic cover 35 in the opposite direction to the fitting direction X1 by contacting the operating lever 34, but the present invention is not limited to this and may be configured not to have the misalignment suppression portion 35j. Also, the misalignment suppression portion 35j may be configured to suppress misalignment of the elastic cover 35 in the opposite direction to the fitting direction X1 by contacting a part of the second housing 32.

[0054] In the above embodiment, the lid 35c has a cylindrical portion 35k protruding from the lid body 35f in a rectangular cylindrical shape, and the press-fit positioning portion 35h and the positional deviation suppression portion 35j are provided on the cylindrical portion 35k, but this is not limited thereto and may be changed to another configuration. For example, the press-fit positioning portion 35h and the positional deviation suppression portion 35j may be configured to protrude from the lid body 35f independently.

[0055] In the above embodiment, the cover 35c is configured so as not to close the operation opening 35a when the operation lever 34 is in the non-engaged position, but this is not limited thereto, and the cover 35c may be configured so as to be able to close the operation opening 35a even when the operation lever 34 is in the non-engaged position.

[0056] In the above embodiment, the elastic cover 35 has a thin hinge portion 35d that connects the cover main body 35b and the lid 35c. However, this is not limited to this. For example, the cover main body 35b and the lid 35c may be separate bodies.

[0057] In the above embodiment, the elastic cover 35 has a contact portion 35m around the entire circumference of the inner surface at the tip end in the fitting direction X1, which contacts the contact surface 41c in a direction intersecting the fitting direction X1. However, this is not limited to this, and the elastic cover 35 may be configured not to have the contact portion 35m.

[0058] In the above embodiment, the elastic cover 35 is configured to cover the bolts 43 when the second housing 32 is fitted into the first housing 22, but this is not limiting and, for example, the elastic cover 35 may not cover the bolts 43. For example, the first connector 21 may be fixed to the device case 41 by a structure other than the bolts 43.

[0059] In the above embodiment, the elastic cover 35 has a tip contact portion 35p at its tip in the fitting direction X1, which contacts the abutment surface 41d of the device case 41 in the fitting direction X1. However, this is not limited to this, and the elastic cover 35 may be configured not to have the tip contact portion 35p.

[0060] In the above embodiment, the contact portion 35m has a contact protrusion 35n that protrudes to locally form strong contact with the contact surface 41c, but this is not limited to this, and the contact portion 35m may be configured not to have the contact protrusion 35n.

[0061] In the above embodiment, the operating lever 34 has a pair of rotational side portions 34a and a connecting portion 34b connecting the pair of rotational side portions 34a, but the present invention is not limited to this and may be changed to an operating portion having a different configuration.
