Description

This disclosure relates to connectors.

Patent document 1 discloses a screw-connection type connector.

JP 2002-237348 A

Due to the structure of screw-connection connectors, it is difficult to prevent the screws from loosening, and loose screws can reduce the reliability of the connection between the male and female housings.

The present disclosure aims to provide a connector that has high connection reliability between a plug and a socket.

An example connector of the present disclosure includes:
a plug having a plug-side connection member;
a socket having a socket-side connecting member releasably connected from the first direction in a state in which the socket-side connecting member can rotate relative to the plug-side connecting member between a first position in a circumferential direction relative to a center line extending in a first direction and a second position in which the plug cannot be removed,
The plug-side connection member is
A main body portion extending along the first direction;
a first restricting member that is fixed to the main body at a position farther from the center line than the main body in a second direction intersecting the first direction, and that restricts movement of the plug relative to the socket in the first direction when the socket and the plug are connected and the socket side connection member is located at the second position;
a second restricting member that is disposed farther from the center line than the main body portion in the second direction and that is disposed movably between a third position that is farther from the socket side connecting member and closer to the first restricting member than the first restricting member in the first direction and a fourth position that is farther from the first restricting member than the third position;
a biasing member that is disposed farther from the socket side connection member than the second restricting member in the first direction and biases the second restricting member from the fourth position toward the third position,
The second restricting member is
When the socket side connection member is located at the second position, the rotation of the socket side connection member from the second position to the first position is restricted when the socket side connection member is located at the third position, and the restriction on the rotation of the socket side connection member relative to the plug side connection member is released when the socket side connection member is located at the fourth position.

According to the connector, when the socket side connection member is in the second position, the first restricting member restricts movement between the socket and the plug in the first direction, and when the second restricting member is in the third position, the second restricting member restricts rotation of the socket side connection member from the second position to the first position relative to the plug side connection member. With this configuration, a connector with high connection reliability between the socket and the plug can be realized.

An example of the present disclosure will be described below with reference to the attached drawings. In the following description, terms indicating specific directions or positions (e.g., terms including "up," "down," "right," and "left") will be used as necessary, but the use of these terms is intended to facilitate understanding of the present disclosure with reference to the drawings, and the meanings of these terms do not limit the technical scope of the present disclosure. In addition, the following description is essentially merely illustrative, and is not intended to limit the present disclosure, its applications, or its uses. Furthermore, the drawings are schematic, and the ratios of the dimensions do not necessarily correspond to reality.

As shown in FIG. 1, the connector 1 of an embodiment of the present disclosure includes a socket 10 and a plug 20 removably connected to the socket 10. A cable 2 is connected to each of the socket 10 and the plug 20. As shown in FIG. 2, the socket 10 has a socket-side connection member 30, and the plug 20 has a plug-side connection member 40. The socket-side connection member 30 is connected releasably from the first direction X in a state in which it can rotate with respect to the plug-side connection member 40 between a first position P1 (see FIG. 4) and a second position P2 in the circumferential direction with respect to the center line CL of the connector 1 extending in the first direction X. As an example, the socket-side connection member 30 is provided with a female thread 11. As an example, the plug-side connection member 40 is provided with a male thread 21 that is releasably fastened to the female thread 11 from the first direction (for example, the X direction). The female thread 11 and the male thread 21 may be omitted.

The socket 10 is provided with a housing portion 12 (see FIG. 3) that houses a socket terminal (not shown) electrically connected to the cable 2. The plug 20 is provided with a plug terminal 22 electrically connected to the cable 2, and is housed in the housing portion of the socket 10. This electrically connects the socket 10 and the plug 20. When the socket 10 and the plug 20 are connected, the space between the socket side connection member 30 and the plug side connection member 40 is sealed to prevent liquid or dust from coming into contact with the socket terminal and the plug terminal.

3, the socket 10 has a socket-side connection member 30 provided with a recess 31. As an example, the socket-side connection member 30 has a substantially cylindrical shape. As an example, the recess 31 has a substantially circular opening 32 on the end face of the socket-side connection member 30 closer to the plug-side connection member 40 in the first direction X, and accommodates the end of the plug-side connection member 40 closer to the socket-side connection member 30 in the first direction X (see FIG. 2). A cylindrical protrusion 33 extending in the first direction X is provided at the approximate center of the recess 31. A gap 34 is provided between the outer peripheral surface of the protrusion 33 and the inner surface of the recess 31 in the radial direction (hereinafter simply referred to as the radial direction) relative to the center line CL of the socket-side connection member 30. The radial direction of the socket-side connection member 30 is an example of the second direction, and is shown as the Y direction in FIG. 2, for example. A plurality of accommodation portions 12 are provided on the end face of the protrusion 33 facing the plug 20.

As shown in FIG. 4, the radial inner surface of the socket-side connection member 30 that constitutes the recess 31 is provided with a release groove 35, a first restricting groove 36, a second restricting groove 37, and a restricting wall portion 38.

The release groove 35 extends from the opening 32 along the first direction X and accommodates the restricting protrusion 53 and the second restricting leg 62 described below. The release groove 35 connects the outside of the socket side connection member 30 to the first restricting groove 36.

The first restricting groove 36 extends in the circumferential direction (hereinafter simply referred to as the circumferential direction) relative to the center line CL and accommodates the restricting protrusion 53. One circumferential end of the first restricting groove 36 is connected to the end of the release groove 35 farther from the opening 32 in the first direction X. A female thread 11 is arranged on each side of the first restricting groove 36 in the circumferential direction. A guide surface 361 is provided on the side of the first restricting groove 36 closer to the opening 32 in the first direction X. The guide surface 361 is curved and inclined in the direction away from the opening 32 in the first direction as it moves away from the release groove 35 in the circumferential direction, and guides the circumferential movement of the restricting protrusion 53. The guide surface 361 is provided at the other circumferential end thereof and has a curved surface 362 that protrudes slightly toward the opening 32 in the first direction X.

The second restricting groove 37 extends in the circumferential direction and accommodates the second restricting leg 62. The second restricting groove 37 is provided independently of the release groove 35 and the first restricting groove 36 in a region 371 that overlaps with the other circumferential end of the first restricting groove 36 at the edge of the opening 32 in the first direction X.

The restricting wall portion 38 is provided between the circumferential release groove 35 and the second restricting groove 37 at the edge of the opening 32, and restricts the movement of the second restricting leg portion 62 in the circumferential direction and in the direction from the second restricting groove 37 toward the release groove 35 when the second restricting leg portion 62 is located in the region 371. An inclined surface 381 is provided at the end of the restricting wall portion 38 closer to the opening 32 in the first direction X, which inclines in the direction approaching the center line CL in the radial direction of the socket side connecting member 30 as it moves away from the opening 32 in the first direction X.

As shown in FIG. 4, in the connector 1, when the socket side connection member 30 is located at the first position P1, the second restricting leg 62 is located at the release groove 35, and when the socket side connection member 30 is located at the second position P2 and the second restricting leg 62 is located at the third position P3 (see FIG. 6) described below, the end of the second restricting leg 62 closer to the socket side connection member 30 in the first direction X is located at the region 371. Note that in FIG. 4, members other than the socket side connection member 30 are omitted, and the restricting protrusion 53 and the second restricting leg 62 when the socket side connection member 30 is located at the first position P1 and the second position P2 are shown by dotted lines.

As shown in FIG. 5, the plug 20 has a plug-side connection member 40, a first restricting member 50, a second restricting member 60, and a biasing member 70.

The plug-side connection member 40 extends along the first direction X, and has a male thread 21 extending in the circumferential direction at the end closer to the socket-side connection member 30 in the first direction X. The plug-side connection member 40 has, as an example, a substantially cylindrical body 41 (one example of a body) and a covering portion 42 provided on the radial outside of the body 41. A recess 43 in which a plurality of plug terminals 22 are accommodated is provided on the end face of the body 41 closer to the socket-side connection member 30 in the first direction X. Each plug terminal 22 protrudes from the bottom surface of the recess 43 in the first direction X. As shown in FIG. 2, the covering portion 42 is disposed farther from the center line CL in the second direction Y than the second restricting member 60. As an example, the covering portion 42 has a substantially cylindrical shape and covers a part of the body 41, a part of the first restricting member 50, and a part of the second restricting member 60. A male screw 21 is provided on a first portion 421 that covers the main body 41 of the covering portion 42. A guide groove 44 that extends along the first direction X and accommodates a guide protrusion 63 of the second restricting member 60 (described later) is provided on a second portion 422 that covers a part of the first restricting member 50 and a part of the second restricting member 60 of the covering portion 42.

As shown in FIG. 2, the first restricting member 50 is fixed to the plug-side connecting member 40 at a position farther from the center line CL in the second direction Y than the plug-side connecting member 40. The first restricting member 50 restricts movement between the plug 20 and the socket 10 in the first direction X when the socket 10 and the plug 20 are connected and the socket-side connecting member 30 is located at the second position P2.

In this embodiment, as shown in FIG. 6, the first restricting member 50 has a first base portion 51 extending in the circumferential direction of the main body portion 41, and a first restricting leg portion 52 extending from the first base portion 51 toward the socket side connecting member 30 along the first direction X. As an example, the first restricting member 50 has a plurality of first restricting legs 52 arranged at intervals in the circumferential direction of the first base portion 51. Note that the covering portion 42 of the plug side connecting member 40 is omitted in FIG. 6.

The first base portion 51 has, as an example, a substantially annular shape extending along the outer circumferential surface of the main body portion 41. Each of the first restricting legs 52 has a substantially rectangular plate shape and is arranged so that the first direction X is the longitudinal direction. A restricting protrusion 53 is provided at the end of each of the first restricting legs 52 that is closer to the socket side connection member 30 in the first direction X. The restricting protrusion 53 extends in the radial direction (an example of the second direction) of the first base portion 51 and in a direction away from the center line CL. The restricting protrusion 53 is provided at the end that is farther from the socket side connection member 30 in the first direction X, and has a curved surface 531 that protrudes in the first direction X and in a direction away from the socket side connection member 30. The curved surface 531, together with the guide surface 361 of the first restricting groove 36, makes it easier to rotate the socket side connection member 30 relative to the plug side connection member 40.

As shown in FIG. 2, the second restricting member 60 is disposed farther from the center line CL than the plug-side connecting member 40 in the second direction Y. As shown in FIG. 6, the second restricting member 60 is configured to be movable in the first direction X between a third position P3 that is farther from the socket-side connecting member 30 and closer to the first restricting member 50 than the first restricting member 50, and a fourth position P4 that is farther from the first restricting member 50 than the third position P3.

6, the second restricting member 60 has a second base portion 61 extending in the circumferential direction of the main body portion 41, a second restricting leg portion 62 extending from the second base portion 61 along the first restricting leg portion 52 toward the socket side connection member 30, and a guide protrusion 63 extending from the second base portion 61 in the radial direction (an example of the second direction) of the main body portion 41. As an example, the second restricting member 60 has a plurality of second restricting legs 62 spaced apart in the circumferential direction of the second base portion 61.

As an example, the second base portion 61 has a substantially annular shape extending along the outer peripheral surface of the main body portion 41. Each second restricting leg portion 62 has a substantially rectangular plate shape and is arranged so that the first direction X is the longitudinal direction. The end 621 of each second restricting leg portion 62 that is closer to the socket side connection member 30 in the first direction X is arranged at a position farther from the socket side connection member 30 in the first direction X than the restricting protrusion 53, as shown in FIG. 6. Each second restricting leg portion 62 has an inclined surface 622 that faces the restricting wall portion 38 when positioned in the release groove 35, as shown in FIG. 4. The inclined surface 622 is inclined in a direction away from the restricting wall portion 38 in the circumferential direction relative to the center line CL as it moves away from the second base portion 61 in the first direction X. 5, the guide protrusion 63 has a generally L-shaped plate shape and is composed of a first portion 631 extending from the second base portion 61 in a radial direction relative to the center line CL of the main body portion 41, and a second portion 632 extending in the first direction and in a direction away from the socket 10. In this embodiment, the guide protrusion 63 is disposed between the second restricting legs 62 adjacent to each other in the circumferential direction of the second base portion 61. Also, as shown in FIG. 5, the outer end of the guide protrusion 63 in the radial direction (an example of the second direction) is disposed on approximately the same plane as the outer end of the covering portion 42 in the radial direction.

The biasing member 70 is, for example, a coil spring. The biasing member 70 is disposed farther from the socket 10 in the first direction X than the second restricting member 60, and biases the second restricting member 60 from the fourth position P4 toward the third position P3.

Next, we will explain the operation when connecting the socket 10 and the plug 20, and the operation when disconnecting the socket 10 and the plug 20.

When connecting the socket 10 and plug 20, the opening 32 of the socket side connection member 30 and the recess 43 of the body 41 of the plug side connection member 40 are brought close to each other and connected while the socket side connection member 30 is located at the first position P1 relative to the plug side connection member 40.

When the socket-side connection member 30 is connected to the plug-side connection member 40, the socket-side connection member 30 is rotated in the circumferential direction to move from the first position P1 to the second position P2. At this time, as shown in FIG. 4, the restricting protrusion 53 of the first restricting leg 52 moves along the guide surface 361 of the first restricting groove 36 to the curved surface 362. The inclined surface 622 of the tip of the second restricting leg 62 contacts the restricting wall 38, and moves over the restricting wall 38 to the region 371 of the second restricting groove 37. When the second restricting leg 62 passes over the restricting wall 38, the second restricting member 60 moves from the third position P3 toward the fourth position P4 against the biasing force of the biasing member 70 (see FIG. 6).

When the socket side connection member 30 moves to the second position P2, the first restricting groove 36 and the restricting protrusion 53 of the first restricting leg 52 restrict movement between the socket 10 and the plug 20 in the first direction X. When the socket side connection member 30 is located at the second position P2, the second restricting member 60 is urged from the fourth position P4 toward the third position P3 by the urging member 70, and the second restricting leg 62 is located in the region 371 of the second restricting groove 37. Therefore, the restricting wall 38 and the second restricting leg 62 restrict rotation of the socket side connection member 30 relative to the plug side connection member 40, and loosening of the fastening between the female thread 11 of the socket 10 and the male thread 21 of the plug 20 can be prevented. In other words, when the plug 20 is located in the second position P2, the second restricting member 60 is configured to restrict rotation of the plug 20 from the second position P2 to the first position P1 when the plug 20 is located in the third position P3, and to release the restriction on rotation of the plug 20 when the plug 20 is located in the fourth position P4.

When disconnecting the socket 10 and the plug 20, the guide protrusion 63 is operated to move the second restricting leg 62 from the third position P3 to the fourth position P4. Then, with the second restricting leg 62 in the fourth position P4, the socket side connection member 30 is rotated in the circumferential direction to move it from the second position P2 to the first position P1. This releases the restriction on movement between the socket 10 and the plug 20 in the first direction X, and by moving the socket 10 and the plug 20 in the first direction and in a direction away from each other, the connection between the socket 10 and the plug 20 is released.

The connector 1 of this embodiment has the following advantages:

In the connector 1, when the socket side connection member 30 is located at the second position P2, the first restricting member 50 restricts movement between the socket 10 and the plug 20 in the first direction X, and when the second restricting member 60 is located at the third position P3, it restricts rotation of the socket side connection member 30 from the second position P2 to the first position P1 relative to the plug side connection member 40. This configuration allows for a connector 1 with high connection reliability between the socket 10 and the plug 20.

The plug-side connection member 40 is disposed farther from the center line CL in the second direction (e.g., radial direction) than the second restricting member 60, and further has a covering portion 42 provided with a guide groove 44 extending along the first direction X. The second restricting member 60 has a second base portion 61 extending in the circumferential direction, and a guide protrusion 63 extending from the second base portion 61 in the second direction (e.g., radial direction) and accommodated in the guide groove 44. With this configuration, a connector 1 with higher connection reliability between the socket 10 and the plug 20 can be realized.

The outer end of the guide protrusion 63 in the second direction (e.g., radial direction) is disposed on approximately the same plane as the outer end of the covering portion 42 in the second direction (e.g., radial direction). This configuration improves the operability of the guide protrusion 63 while improving the usability of the connector 1.

The first restricting member 50 has a first base portion 51 extending in the circumferential direction, and a first restricting leg portion 52 extending from the first base portion 51 toward the socket side connecting member 30 along the first direction X, and having a restricting protrusion 53 provided at an end closer to the socket side connecting member 30 in the first direction X and extending in a second direction (e.g., radial direction) and in a direction away from the center line CL. The second restricting member 60 extends from the second base portion 61 toward the socket side connecting member 30 along the first restricting leg portion 52, and has a second restricting leg portion 62 whose end closer to the socket side connecting member 30 in the first direction X is disposed at a position farther from the socket side connecting member 30 in the first direction X than the restricting protrusion 53. The socket side connecting member 30 has an opening 32 on an end face closer to the plug side connecting member 40 in the first direction X, and a recess 31 for accommodating an end of the plug side connecting member 40 closer to the socket side connecting member 30 in the first direction X. On the inner surface in the second direction (e.g., radial direction) of the socket side connecting member 30 constituting the recess 31, there are provided a release groove 35 extending from the opening 32 along the first direction X and accommodating the regulating protrusion 53 and the second regulating leg 62, a first regulating groove 36 extending in the circumferential direction, one circumferential end of which is connected to the end of the release groove 35 farther from the opening 32 in the first direction X and accommodating the regulating protrusion 53, a second regulating groove 37 provided independently of the release groove 35 and the first regulating groove 36 in a region 371 which overlaps in the first direction X with the other circumferential end of the first regulating groove 36 at the edge of the opening 32 and accommodates the second regulating leg 62, and a regulating wall portion 38 provided between the circumferential release groove 35 and the second regulating groove 37 at the edge of the opening 32 and which regulates movement of the second regulating leg 62 in the circumferential direction and in the direction from the second regulating groove 37 toward the release groove 35 when the second regulating leg 62 is located in the region 371. When the socket side connection member 30 is in the first position P1, the second restricting leg 62 is in the release groove 35, and when the socket side connection member 30 is in the second position P2 and the second restricting member 60 is in the third position P3, the end of the second restricting leg 62 farther from the second base portion 61 in the first direction X is in the region 371. This configuration makes it possible to realize a connector 1 with higher connection reliability between the socket 10 and the plug 20.

The second restricting leg 62 has an inclined surface 622 that faces the restricting wall 38 when the second restricting leg 62 is positioned in the release groove 35. The inclined surface 622 is inclined in a direction away from the restricting wall 38 in the circumferential direction as it moves away from the second base portion 61 in the first direction X. This configuration allows the socket side connecting member 30 to be easily rotated from the first position P1 toward the second position P2.

The socket side connection member 30 has a plurality of second restricting legs 62, and a guide protrusion 63 is disposed between adjacent second restricting legs 62 in the circumferential direction. With this configuration, the second restricting member 60 can be easily manufactured, and therefore a connector 1 with high connection reliability between the socket 10 and the plug 20 can be easily realized.

The connector 1 can also be configured as follows:

The guide groove 44 and guide protrusion 63 of the covering portion 42 can be omitted.

The guide protrusion 63 may be configured to protrude beyond the outer end of the covering portion 42 in the second direction (e.g., the radial direction), or may be configured to be receivable within the guide groove 44.

The male thread 21 does not necessarily have to be provided on the covering portion 42, but may be provided on the main body portion 41, for example.

As shown in FIG. 7, the restricting wall portion 38 may be provided with an inclined surface 382 that faces the second restricting leg portion 62 when the second restricting leg portion 62 is positioned in the release groove 35. The inclined surface 382 is inclined in the circumferential direction away from the release groove 35 as it approaches the opening 32 in the first direction X. When the inclined surface 382 is provided on the restricting wall portion 38, the inclined surface 622 of the second restricting leg portion 62 may be omitted as shown in FIG. 8. Even in this case, the socket side connecting member 30 can be easily rotated from the first position P1 to the second position P2.

The present disclosure is not limited to the above embodiment, but can be applied to any connector configured such that when the socket-side connecting member is located in the second position, the first restricting member restricts movement between the socket and the plug in the first direction, and when the second restricting member is located in the third position, the socket-side connecting member restricts rotation from the second position to the first position relative to the plug-side connecting member.
