Description

Shielded connector

Technical Field

The present invention relates to a shielded connector.

Background

Conventionally, there has been proposed a shielded connector including: a terminal-equipped wire having a terminal connected to a terminal of the wire; a housing holding the terminal-equipped wire; a shield case assembled to the housing; and a waterproof plug sealing between the terminal wire and the housing. For example, in one of conventional shield connectors, a terminal-equipped wire is held by a housing, and an engaging portion provided in the housing is engaged with an engaged portion provided in a shield shell. The waterproof plug is configured to be pressed against the inner peripheral surface of the housing to seal between the housing and the electric wire (see, for example, patent document 1).

Disclosure of Invention

Technical problem to be solved by the invention

However, the housing used in the shielded connector is generally made of a resin material. A sealing member such as a waterproof plug or a gasket is configured to be in press contact with the inner peripheral surface of the housing in order to seal between the strip terminal electric wire and the housing. For example, when the shield connector configured as described above is used in a high-temperature environment, the housing itself may be deformed by an elastic force (so-called surface pressure) of the sealing member.

Taking the shielded connector described in patent document 1 as an example, since the inner peripheral surface of the housing is in press contact with the waterproof plug, a force toward the outside in the radial direction of the housing is applied to the housing by the elastic force of the waterproof plug. Therefore, the housing may be deformed to expand its diameter. If the housing is deformed in this manner, a gap is formed between the housing and the waterproof plug. That is, the hermeticity of the connector (including the shield connector) may be reduced.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a shielded connector in which a decrease in sealing performance is suppressed.

Means for solving the problems

To achieve the above object, the shield connector of the present invention is characterized by the following [1] to [4].

[1] A shielded connector is provided with:

a terminal-equipped wire to which a terminal is connected at an end of the wire;

a case having a body portion configured to have an opening and to receive the terminal-equipped wire, and a cover portion configured to be assembled to the body portion and to close the opening;

a gasket configured to seal a space between the terminal-equipped wire and the housing and a space between the body portion and the lid portion together; and

a shield case configured to be assembled to the housing so as to be in close contact with the housing,

the shield case has a cylindrical portion configured to be press-fitted into the housing.

[2] The shielded connector according to item 1 above, wherein,

the space between the terminal-equipped electric wire and the housing refers to a space between the terminal-equipped electric wire and the body portion and a space between the terminal-equipped electric wire and the cover portion.

[3] The shielded connector according to the above [1] or [2],

the gasket and the cylindrical portion of the shield case are positioned so as to sandwich at least a part of the housing in the entire circumferential direction along the radial direction of the housing.

[4] The shielded connector according to item 3 above, wherein,

a first portion of the gasket that seals the space between the terminal-equipped electric wire and the housing has a thickness greater than a second portion of the gasket other than the first portion,

the at least one portion of the housing is a portion corresponding to the first portion.

The shielded connector having the structure of [1] will be described below. The shield connector of this configuration is provided with a terminal-equipped wire, a housing, a gasket, and a shield shell. The case has a body portion in which the electric wire with the terminal is housed and a lid portion assembled so as to close an opening of the body portion, and the gasket seals between the electric wire with the terminal and the case and between the body portion and the lid portion collectively. The shield case is assembled in close contact with the housing. The shield case has a cylindrical portion into which the case is press-fitted. Thus, for example, when the shielded connector of the present configuration is used in a high-temperature environment, even if a force toward the outside in the radial direction of the housing is applied to the housing by the elastic force of the gasket, the shield shell is in close contact with the housing, and thus deformation of the housing expanding in the radial direction is suppressed. That is, the possibility of a gap being generated between the housing and the gasket is suppressed. Further, since the case is press-fitted into the cylindrical portion of the shield case, the state in which the body portion of the case is pressed against the lid portion and the lid portion is pressed against the body portion is maintained. Thereby, the assembled state of the body portion and the cover portion is appropriately maintained, and the sealing property of the shield connector is appropriately maintained. As a result, the reduction in the hermeticity of the shield connector of the present configuration is suppressed.

According to the shielded connector of the above configuration [2], since the gasket seals between the electric wires with terminals and the housing, that is, between the electric wires with terminals and the body portion, and between the electric wires with terminals and the cover portion, the housing is also excellent in sealing property when it is configured by two members of the body portion and the cover portion like the housing of this configuration.

According to the shielded connector of the above-described configuration of [3], since at least a part of the housing is sandwiched between the gasket and the cylindrical portion of the shield shell in the radial direction of the housing and over the entire circumferential region of the housing, the housing is sealed by the gasket, and deformation of the housing is suppressed by the shield shell.

The shielded connector having the structure of [4] will be described below. The portion of the gasket for sealing between the electric wire with terminal and the housing is formed to have the thickest wall in the gasket. The elastic force of the gasket is applied most to the portion of the housing corresponding to the portion of the gasket. Therefore, the portion of the case is sandwiched by the gasket and the shield case, and thus, the deformation of the case is suppressed in the same manner as in the above [2 ].

Effects of the invention

As described above, according to the present invention, it is possible to provide a shielded connector in which a decrease in sealing performance is suppressed.

The present invention has been briefly described. Further, the details of the present invention will be further clarified by reading the embodiments for carrying out the present invention described below with reference to the drawings.

Detailed Description

< embodiment >

The shielded connector 1 of the present embodiment is attached to a panel of a vehicle or the like, for example, and is connected to an inverter, a motor, and the like. Hereinafter, a shielded connector 1 according to an embodiment of the present invention will be described with reference to the drawings.

Hereinafter, for convenience of explanation, "front-back direction", "up-down direction", "width direction", "front", "back", "up", and "down" are defined as shown in fig. 1 to 10. The "front-rear direction", "width direction", and "vertical direction" are orthogonal to each other. The front-rear direction coincides with the fitting direction of the shielded connector 1 and the mating connector (not shown). The front side (side closer to the mating connector) of the shield connector 1 in the fitting direction is referred to as "front", and the side (side farther from the mating connector) of the shield connector 1 on which the fitting direction is released is referred to as "rear". Specifically, in fig. 1, the left and right directions are front and rear, respectively. Further, the radial direction of the casing 3 is simply referred to as "radial direction", and the circumferential direction of the casing 3 is simply referred to as "circumferential direction".

As shown in fig. 1 to 3, the shielded connector 1 includes a shielded shell 2, a housing 3, a gasket 4, and a terminal-equipped wire 5. The shield shell 2, the housing 3, the packing 4, and the terminal-equipped wire 5 are the shield connector 1, respectively. Further, in the example shown in fig. 1, a seal member 6 that seals between the shield connector 1 and the mating connector is provided at a front portion of the housing 3.

As shown in fig. 4 and 5, the gasket 4 includes a shaft seal portion 41 and a surface seal portion 42, the shaft seal portion 41 seals between the strip terminal electric wire 5 and the housing 3, and the surface seal portion 42 seals between the body portion 31 and the lid portion 32 of the housing 3, which will be described later.

The shaft seal portion 41 (first portion) is formed to have the largest thickness in the gasket 4. That is, the thickness of the shaft seal portion 41 is greater than the thickness of the face seal portion 42 (second portion). In the present embodiment, the thickness refers to a thickness along the radial direction of the housing 3. In the shaft seal portion 41, a plurality of hole portions 41a (3 in this example) through which the terminal-equipped electric wires 5 are inserted are provided in the axial direction. The face seal portion 42 has a substantially rectangular C-shape.

The gasket 4 has an annular shape by the shaft seal portion 41 and the surface seal portion 42, and collectively seals between the terminal-equipped wire 5 and the housing 3 and between the body portion 31 and the cover portion 32 (see fig. 5 and 6). Further, between the terminal-equipped wire 5 and the housing 3 specifically means between the terminal-equipped wire 5 and the body portion 31 and between the terminal-equipped wire 5 and the lid portion 32.

The terminal-equipped electric wire 5 has an electric wire 51 extending in the front-rear direction and a terminal 52 connected to a tip (front end portion in this example) of the electric wire 51. The terminal 52 extends in the vertical direction except for the connection portion with the electric wire 51. That is, in the present embodiment, the terminal 52 is configured to be substantially perpendicular to the wire 51. The terminal-equipped wire 5 is inserted into the hole 41a of the gasket 4 and then housed in the housing 3 (see fig. 3 and 5 to 6), as will be described later.

Although not shown, a braid is provided on the outer periphery of the electric wire 51 to suppress the intrusion of noise from the outside.

The terminal-equipped wire 5 and the gasket 4 are housed in the case 3 as described later. That is, for example, when the shield connector 1 is used in a high-temperature environment, a force directed radially outward is applied to the housing 3 by the elastic force of the gasket 4 (see arrows Y1 to Y4 in fig. 5 and 6).

In the present embodiment, since the thickness of the shaft seal portion 41 is larger than the thickness of the surface seal portion 42, the elastic force of the gasket 4 is likely to be affected particularly at a portion of the housing 3 corresponding to the shaft seal portion 41 (a sandwiched portion 30 described later).

In view of the above, the shield connector 1 of the present embodiment is configured to suppress a reduction in the sealing performance of the shield connector 1 by suppressing deformation of the housing 3 due to the elastic force of the gasket 4.

First, each element constituting the shielded connector 1 will be described below.

First, the case 3 will be explained. The housing 3 is a resin molded body made of a resin material. As shown in fig. 7, the housing 3 includes a body portion 31 that houses the terminal-equipped wire 5 and a lid portion 32 that is attached to the body portion 31. The case 3 is configured by assembling the body portion 31 and the lid portion 32 in the vertical direction.

As shown in fig. 7 and 8, the body 31 includes a housing 311, an engaging projection 312, an engaged portion 313, and a cover 314. The receiving portion 311 is open at the lower side thereof, and receives a plurality of terminal-equipped electric wires 5 (3 in this example). In the housing portion 311, a plurality of housing chambers (3 in this example) are provided corresponding to the plurality of terminal-equipped electric wires 5 to be housed.

The housing 311 is composed of a first portion 311a and a second portion 311b, the first portion 311a houses a portion of the terminal-equipped wire 5 where the gasket 4 is attached, and the second portion 311b houses the wire 51 of the terminal-equipped wire 5 located rearward of the portion where the gasket 4 (particularly the shaft seal 41) is attached.

The engaging projections 312 are provided on the wall portions in the width direction and the front of the housing portion 311 (first portion 311 a), and engage with an engaged portion 322 of the lid portion 32 described later. The engaged portion 313 is provided on a wall portion behind the housing portion 311 (second portion 311 b), and extends downward from the rear wall portion. The engaged portion 313 engages with an engagement projection (not shown) of the cover portion 32 described later.

The cover portion 314 is provided continuously with the front end portion of the wall portion above the housing portion 311, and has a substantially elliptical cylindrical shape with an opening penetrating in the front-rear direction. The front end of the cover 314 protrudes forward beyond the front end of the housing 311. A seal member 6 (see fig. 1) for sealing between the shield connector 1 and the mating connector when the shield connector is fitted is attached to the outer peripheral surface of the distal end portion of the cover portion 314.

The main body 31 is provided with a hole 315 for communicating an upper wall of the housing 311 with a lower wall of the cover 314, and the terminal 52 is inserted into the hole 315. The tip end portion of the terminal 52 (i.e., a portion connected to a terminal (not shown) of the mating connector) is inserted into the hole 315 and positioned inside the cover 314 (see fig. 2).

As shown in fig. 7, the lid portion 32 is opened upward, and when the terminal-equipped wire 5 is received in the receiving portion 311, the lid portion 32 is assembled to the body portion 31 so as to close the opening of the receiving portion 311. The lid portion 32 is constituted by a first portion 32a and a second portion 32b, the first portion 32a closing the opening of the first portion 311a of the body portion 31, and the second portion 32b closing the opening of the second portion 311b of the body portion 31.

When the lid portion 32 is assembled to the body portion 31, the first portion 311a of the body portion 31 and the first portion 32a of the lid portion 32 constitute the first part 3a of the housing 3, and the second portion 311b of the body portion 31 and the second portion 32b of the lid portion 32 constitute the second part 3b.

The first portion 3a of the housing 3 accommodates a portion of the terminal-equipped wire 5 where the gasket 4 is attached, and the second portion 3b accommodates the wire 51 of the terminal-equipped wire 5 located rearward of the portion where the gasket 4 (particularly, the shaft seal portion 41) is attached.

The cover 32 includes a rib 321, an engaged portion 322, and an engaging projection (not shown). The rib 321 is provided on the outer peripheral surface of the bottom wall of the lid portion 32 (particularly, the first portion 32 a), protrudes downward from the outer peripheral surface, and extends in the front-rear direction. The rib 321 has a substantially rectangular parallelepiped shape having a rectangular shape (see fig. 10 a) in front view. As will be described later, the rib 321 functions as a press-fitting rib when the shield case 2 is assembled to the housing 3.

The engaged portion 322 is provided on the wall portion in the width direction and the front of the cover portion 32 (particularly, the first portion 32 a), and extends upward from each wall portion. The engaged portion 322 engages with the engaging projection 312 of the body 31. The engaging protrusion is provided on a wall portion behind the cover portion 32 (particularly the second portion 32 b) and engages with the engaged portion 313 of the body portion 31.

The housing 3 has a sandwiched portion 30 sandwiched by the shield case 2 and the gasket 4 in the radial direction and over the entire circumferential region as described later. The sandwiched portion 30 is specifically a portion of the housing 3 that accommodates the shaft seal portion 41 (i.e., that is in pressing contact with the shaft seal portion 41).

The housing 3 is further provided with an elastically deformable cantilever-like lock arm 33. The lock arms 33 are provided on the wall portions in the width direction of the main body portion 31 (particularly, the first portion 311 a), and engage with engagement holes 24 of the shield case 2 described later.

The above is a description of the housing 3.

Next, the shield case 2 will be explained. The shield case 2 is made of a metal material, and suppresses intrusion of noise from the outside. The shield case 2 is assembled while sliding on the outer peripheral surface of the housing 3 from the rear of the housing 3 in the front-rear direction. Therefore, the shield case 2 has a shape corresponding to the outer peripheral shape of the housing 3.

As shown in fig. 9, the shield shell 2 has a first member 21 mounted to the first portion 3a of the housing 3 (also including the hood 314) and a second member 22 mounted to the second portion 3b of the housing 3. The first member 21 and the second member 22 are fastened and electrically connected via a fastening member 23.

The first member 21 is provided with a cylindrical portion 211 that is in close contact with the outer peripheral surface of the sandwiched portion 30 of the housing 3. The housing 3 is press-fitted into the cylindrical portion 211. The cylindrical portion 211 has a substantially rectangular cylindrical shape with a bottom that opens forward. The bottom wall 212 of the cylindrical portion 211 is provided with a hole 213. The hole 213 is sized to allow the second portion 3b of the housing 3 to be inserted therethrough. Fastening holes 214 for fastening with the second member 22 are provided at both ends of the bottom wall 212 in the width direction, respectively.

The first member 21 further has a front end portion 215 provided continuously to the front of the cylindrical portion 211. The distal end portion 215 is in close contact with the outer peripheral surface of the cover portion 314 of the housing 3. A flange portion 216 having a fastening hole 217 is provided at the front end edge of the front end portion 215. The fastening hole 217 is a hole through which a fastening member (not shown) is inserted when the shield connector 1 is fastened and fixed to a conductive member (not shown). Examples of the conductive member include a panel of a vehicle.

The second member 22 has a cylindrical portion 221 covering the periphery of the second portion 3b of the housing 3 and a flange portion 222 provided at the front end edge of the cylindrical portion 221. The cylindrical portion 221 has a substantially elliptical cylindrical shape with an opening penetrating in the front-rear direction. The flange portions 222 are provided with fastening holes 223 at positions corresponding to the fastening holes 214 of the first member 21, respectively.

The shield shell 2 needs to be electrically connected to a braid (not shown) covering the outer periphery of the electric wire 51 of the terminal-equipped electric wire 5. Therefore, a clamp ring 7 that grounds the end of the braid to the shield shell 2 is attached to the outer peripheral surface of the rear end (i.e., the cylindrical portion 221) of the shield shell 2. Thereby, the braid is electrically connected to the shield shell 2. Further, as described above, since the shield shell 2 is fastened and fixed to the conductive member (for example, a panel of a vehicle), the braid, the shield shell 2, and the conductive member are electrically connected to each other.

The shield case 2 is provided with an engagement hole 24 that engages with the lock arm 33 of the housing 3. The engagement holes 24 are provided at positions corresponding to the lock arms 33, respectively.

The above is a description of the shield case 2.

Next, a manufacturing process of the shielded connector 1 will be described. First, the seal gasket 4 is mounted on the terminal-equipped electric wire 5. As the step of attaching the gasket 4 to the terminal-equipped wire 5, the rear end of the terminal-equipped wire 5 may be inserted into the hole 41a of the gasket 4, or the terminal 52 of the wire 51 may be connected to the terminal after the wire 51 is attached to the gasket 4.

After the mat seal 4 is attached to the terminal-equipped wire 5, the terminal-equipped wire 5 and the mat seal 4 are housed in the body portion 31 of the case 3. After the terminal-equipped wire 5 and the gasket 4 are housed in the body 31, the lid 32 is assembled to the body 31 so as to close the body 31.

In the present embodiment, unlike the conventional shielded connector, the terminal 52 is configured to be substantially perpendicular to the wire 51, and therefore the housing 3 includes two members, i.e., the body 31 and the cover 32, and the cover 32 is configured to be assembled to the body 31 in the vertical direction.

In a state where the terminal-equipped wire 5 and the gasket 4 are housed in the case 3, the inner peripheral surface of the case 3 is in press contact with the gasket 4. That is, the gasket 4 seals the space between the terminal-equipped wire 5 and the housing 3 and the space between the body portion 31 and the lid portion 32 (see also fig. 5).

Then, the shield case 2 is assembled to the housing 3 by being moved in the front-rear direction from the rear of the housing 3. Specifically, the shield shell 2 is moved relative to the housing 3 so that the inner peripheral surface of the shield shell 2 slides relative to the outer peripheral surface of the housing 3. In other words, the housing 3 is press-fitted into the cylindrical portion 211 of the shield case 2.

As described above, when the shield case 2 is assembled to the housing 3, the body portion 31 and the lid portion 32 of the housing 3 are pressed in the direction of abutting against each other. This improves the sealing property between the body 31 and the lid 32.

When the shield case 2 moves to a predetermined position of the housing 3, the lock arm 33 of the housing 3 engages with the engagement hole 24 of the shield case 2. Thereby, the shielded connector 1 is obtained.

The above is a description of the manufacturing process of the shielded connector 1.

As described above, the shield shell 2 of the shield connector 1 is in close contact with the housing 3, and the shield shell 2 and the gasket 4 are located at positions where the sandwiched portion 30 of the housing 3 is sandwiched in the radial direction and over the entire circumferential region.

In other words, as shown in fig. 6 (b), the inner peripheral surface of the sandwiched portion 30 of the housing 3 is in press contact with the shaft seal portion 41 of the gasket 4, and the outer peripheral surface is in close contact with the inner peripheral surface of the shield shell 2. Thus, the shielded connector 1 has excellent waterproof property even when used in a high-temperature environment, and deformation of the housing 3 spreading radially outward is suppressed by the shield shell 2.

In the present embodiment, since the housing 3 is press-fitted into the cylindrical portion 211 of the shield shell 2, the housing 3 is pressed radially inward by the shield shell 2, and the diameter thereof is reduced. Thus, the engagement state between the engagement projection 312 of the body 31 and the engaged portion 322 of the cover 32 may be loosened (in other words, the engagement projection 312 and the engaged portion 322 may not be in an appropriate engagement state). However, when the diameter of the case 3 is reduced, the gasket 4 is pressed radially inward by the case 3, and the gasket 4 is elastically deformed as if it is crushed. Therefore, even when the engagement projection 312 and the engaged portion 322 are not in an appropriate engagement state as described above, the sealing performance of the shield connector 1 is maintained by the elastic deformation of the gasket.

In the present embodiment, since the thickness of the shaft seal portion 41 is greater than the thickness of the face seal portion 42, the elastic force of the gasket 4 is applied most to the portion of the housing 3 that is in pressing contact with the shaft seal portion 41 (i.e., the sandwiched portion 30) even when the portion is in pressing contact with the gasket 4. Therefore, at least the sandwiching portion 30 is sandwiched by the gasket 4 and the shield case 2.

< action/Effect >

The shielded connector 1 of the present embodiment includes a terminal-equipped wire 5, a housing 3, a gasket 4, and a shield shell 2. The case 3 has a body portion 31 in which the terminal-equipped wire 5 is housed and a lid portion 32 assembled so as to close an opening of the body portion 31, and the gasket 4 seals the space between the terminal-equipped wire 5 and the case 3 and the space between the body portion 31 and the lid portion 32 collectively. The shield case 2 is assembled to be in close contact with the housing 3. Thus, for example, when the shielded connector 1 is used in a high-temperature environment, for example, even if a force toward the outside in the radial direction of the housing 3 is applied to the housing 3 by the elastic force of the gasket 4, the shield shell 2 is in close contact with the housing 3, and thus deformation of the housing 3 spreading outward in the radial direction is suppressed.

Specifically, as shown in fig. 6 b, a force directed radially outward (see arrows Y3 to Y4) is applied to the housing 3 by the elastic force of the shaft seal portion 41, but the deformation of the housing 3 that expands radially outward is suppressed by the shield shell 2 even when the shield connector 1 is used in a high-temperature environment because the shield shell 2 is in close contact with the outer peripheral surface of the housing 3. That is, the possibility of a gap being generated between the housing 3 and the gasket 4 is suppressed.

In addition, since the housing 3 is press-fitted into the cylindrical portion 211 of the shield case 2, the state in which the body portion 31 is pressed against the lid portion 32 and the lid portion 32 is pressed against the body portion 31 is maintained. Thereby, the assembled state of the body portion 31 and the cover portion 32 is appropriately maintained, and the sealing property of the shield connector 1 is appropriately maintained.

Further, according to the shielded connector 1 of the present embodiment, since the gasket 4 seals between the terminal-attached electric wire 5 and the housing 3, that is, between the terminal-attached electric wire 5 and the body portion 31, and between the terminal-attached electric wire 5 and the cover portion 32, the housing is excellent in sealing property even when the housing is configured by two members of the body portion 31 and the cover portion 32 like the housing 3 of the present embodiment.

Further, according to the shield connector 1 of the present embodiment, since at least a part of the housing 3 is sandwiched by the gasket 4 and the cylindrical portion 211 of the shield shell 2 in the radial direction of the housing 3 and over the entire circumferential region of the housing 3, the housing 3 is sealed by the gasket 4, and deformation of the housing 3 is suppressed by the shield shell 2.

Further, in the shield connector 1 of the present embodiment, since the shaft seal portion 41 of the gasket 4 is configured to be the thickest among the gaskets, the elastic force of the gasket 4 is applied to the sandwiched portion 30 most in the housing 3. Therefore, the sandwiched portion 30 is sandwiched between the gasket 4 and the shield case 2, and thus deformation of the housing 3 is suppressed.

As a result, the reduction in the hermeticity of the shield connector 1 of the present embodiment is suppressed.

< other mode >

The present invention is not limited to the above embodiments, and modifications, improvements, and the like can be appropriately made. The material, shape, size, number, arrangement position, and the like of each component in the above embodiments are arbitrary as long as the present invention can be realized, and are not limited.

In the present embodiment, only the portion of the housing 3 that is in pressing contact with the shaft seal portion 41 (i.e., the sandwiched portion 30) is sandwiched between the gasket 4 and the shield shell 2, but the portion of the housing 3 that is in pressing contact with the surface seal portion 42 or the entire housing 3 may be sandwiched between the gasket 4 and the shield shell 2.

Further, as in the present embodiment, only the sandwiched portion 30 is sandwiched between the gasket 4 and the shield shell 2, whereby the reduction in the sealing property of the shield connector 1 can be suppressed, and the embodiment of the present embodiment is preferable from the viewpoint of the manufacturing cost.

As shown in fig. 10 (b), a protruding portion 321a protruding further downward from a wall portion below the rib 321 may be provided. Since the rib 321 is provided with the projecting portion 321a, when the shield case 2 is assembled to the housing 3, the projecting portion 321a is crushed to absorb relative movement (so-called rattling) between the housing 3 and the shield case 2 according to an assembly tolerance.

The protruding portions 321a may be provided to extend continuously in the extending direction of the rib (in the present example, the front-rear direction), or may be provided to be scattered in the extending direction of the rib.

Here, the features of the above-described embodiments of the shielded connector according to the present invention are briefly summarized and listed as the following [1] to [4].

[1]

A shielded connector (1) is provided with:

a terminal-equipped wire (5) to which a terminal (52) is connected at an end of a wire (51);
