Description

Technical Field

[0001] The present invention relates to a connector. Background Art

[0002] In the past, connectors having detection components for detecting the mating state of the connector are known, such as those described in the following patent documents 1 to 4. The connector described in the following patent document 1 can press the detection component into the detection position below the locking arm when the male connector and the female connector are fully mated. In this way, it can be known that the connector is fully mated. In the stage before the male connector and the female connector are fully mated, even if the detection component is to be pressed into the detection position, it abuts against the locking arm that is elastically deformed downward and cannot be pressed in. In this way, it can be known that the connector is in an incompletely mated state. The detection component of the connector described in the following patent document 4 is mounted on the locking arm in a manner that allows it to be elastically deformed integrally with the locking arm. The height position of the locking arm is arranged at a relatively high position so that the detection component does not contact the housing when the locking arm is elastically deformed downward.

[0004] However, in the connector of the above structure, in order to separate the mated connectors, the detection member is moved backward from the detection position, and the lock arm is elastically deformed downward to release the lock. If the detection member is to be installed in a manner that elastically deforms together with the lock arm, if the height position of the lock arm is not raised, the detection member moving backward contacts the housing, and sometimes it is difficult to elastically deform the lock arm. Therefore, there is a desire to easily release the lock of the lock arm.

[0005] Therefore, an object of the present invention is to provide a connector that can easily release the lock of a lock arm. Solutions to Solve Problems

[0006] The connector of the present invention comprises: a shell; an elastically deformable locking arm, which is arranged on the shell and is locked with a locking portion arranged on the mating connector in a mating state with the mating connector; and a detection member, which is installed on the locking arm in a manner that can move between a first position and a second position, and is allowed to move from the first position to the second position in the mating state, the shell having an opposing surface, the opposing surface being opposed to the locking arm, forming a bending space between the opposing surface and the locking arm, the opposing surface having a recess, and when the locking arm is elastically deformed during the mating process with the mating connector when the detection member is arranged in the first position, the detection member enters the recess.

[0007] According to the present invention, it is possible to provide a connector in which the lock of the lock arm can be easily released. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. (1) The connector of the present invention comprises: a housing; an elastically deformable locking arm provided on the housing, and locked with a locking portion provided on the mating connector in a mating state with the mating connector; and a detection member, mounted on the locking arm in a manner that allows movement between a first position and a second position, and allowed to move from the first position to the second position in the mating state, the housing having an opposing surface, the opposing surface opposing the locking arm, forming a bending space between the opposing surface and the locking arm, the opposing surface having a recess, and the detecting member entering the recess when the locking arm is elastically deformed during the mating process with the mating connector when the detecting member is arranged in the first position. According to such a structure, when the connector in the mating state is separated, the locking arm is elastically deformed after the detecting member is moved from the second position to the first position. At this time, the detecting member arranged in the first position is displaced with the elastic deformation of the locking arm and enters the recess of the opposing surface. Therefore, even if the height position of the locking arm is not raised, the detection member can prevent the locking arm from being difficult to be elastically deformed, and the locking of the locking arm can be easily released. (2) Alternatively, in the connector described in (1) above, the recess has a movement limiting surface, and the movement limiting surface is located forward of the detection member in the state of entering the recess in the direction of movement from the first position to the second position. According to such a structure, when the locking arm is in the elastically deformed state, even if the detection member is to be pressed from the first position to the second position, the detection member collides with the movement limiting surface and cannot move. Because the movement limiting surface that limits the movement of the detection member from the first position to the second position is provided in the recess, the housing can be miniaturized compared to the case where the movement limiting surface is provided in a position different from the recess. (3) Alternatively, in the connector described in (1) or (2) above, the detection member has a locking portion, the locking portion is locked with at least one of the locking arm and the housing at the second position, and when the detection member enters the recess, the locking portion is located behind the movement limiting surface in the direction of movement from the first position to the second position. According to such a structure, the locking portion has the function of locking with at least one of the locking arm and the housing at the second position, and the function of contacting with the movement limiting surface to prevent the detection member from moving from the first position to the second position. Therefore, compared with a case where these functions are provided at different locations, the detection member can be miniaturized. (4) Alternatively, in any one of the connectors described in (1) to (3), there is a stopper, the stopper being locked with a terminal part received in a terminal receiving chamber of the housing, the housing being provided with a stopper mounting portion communicating with the terminal receiving chamber, and when the direction in which the locking arm is elastically deformed is taken as the up-down direction, the formation range of the recess in the up-down direction of the housing is limited to the formation range of the stopper mounting portion in the up-down direction of the housing. According to such a structure, in the housing having the stopper mounting portion, the recess can be formed without increasing the size in the up-down direction, so that the housing can be prevented from being enlarged.

[0010] [Details of Embodiments of the Invention] Specific examples of the connector of the present invention are described below with reference to the drawings. The present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0011] [Implementation Method 1] like Figure 1 As shown, the connector 10 includes a housing 20 that can be mated with the cover 12 of the other connector 11, and a detection member 50 that detects the mating state with the other connector 11. The housing 20 contains terminal parts (not shown). The housing 20 is provided with a locking arm 22 that can be elastically deformed. Figure 2 As shown, the lock arm 22 is locked with the lock portion 13 provided on the mating connector 11 , so that the connector 10 and the mating connector 11 are held in the mating state.

[0012] In the following description of the connector 10, the front side in the mating direction with the mating connector 11 is referred to as the front side, and the side provided with the locking arm 22 is referred to as the upper side. The left-right direction is based on the left-right direction when the connector 10 is viewed from the front side. In each figure, the positive direction side of the X axis represents the front side, the negative direction side of the X axis represents the rear side, the positive direction side of the Y axis represents the upper side, the negative direction side of the Y axis represents the lower side, the positive direction side of the Z axis represents the left side, and the negative direction side of the Z axis represents the right side. These directions are not necessarily consistent with the directions of the connector 10 when it is mounted on a vehicle or the like.

[0013] The housing 14 of the mating connector 11 is made of synthetic resin. The cover 12 of the mating connector 11 is in the shape of a square tube. The housing 14 of the mating connector 11 holds a mating terminal part 15 (see Fig.12 The other terminal part 15 is made of conductive metal and has a protrusion protruding into the cover part 12. The other terminal part 15 is connected to the substrate 100. Figure 2 As shown, the locking portion 13 protrudes toward the inner side of the cover portion 12 .

[0014] The housing 20 is made of synthetic resin, such as Figure 3 As shown, the housing body 21 and the locking arm 22 are provided. The housing body 21 has a plurality of terminal storage chambers 23 on the left and right sides of the locking arm 22. Terminal parts not shown are stored in each terminal storage chamber 23. The terminal parts are electrically connected to the other terminal parts 15 when the connector 10 and the other connector 11 are mated. The terminal parts are connected to the terminal end of the electric wire not shown.

[0015] like Figure 1 and Fig.15 As shown in FIG. 1 , a stopper 24 is installed in the housing 20. The stopper 24 is locked with the terminal parts stored in each terminal storage chamber 23 to prevent the terminal parts from falling off. The stopper 24 includes a fall-off prevention portion 24A and a stopper locking portion 24B. The fall-off prevention portion 24A protrudes into the terminal storage chamber 23 (see FIG. 1 ). Figure 5 The stopper locking portion 24B is locked with the left and right side surfaces of the housing 20 .

[0016] like Figure 1 As shown in FIG. 1 , the stopper 24 is mounted to a stopper mounting portion 25 provided on the housing 20. The stopper mounting portion 25 communicates with the terminal storage chamber 23. The stopper mounting portion 25 is provided from the lower surface of the housing 20 to the left and right side surfaces of the housing 20. The formation range of the stopper mounting portion 25 in the vertical direction of the housing 20 is from the height position of the upper end of the stopper locking portion 24B to the lower surface of the housing 20. In other words, the formation range of the stopper mounting portion 25 is a portion of the housing 20 that is recessed for mounting the stopper 24.

[0017] like Figure 3As shown, a recessed portion 26 is formed in the left-right central portion of the upper surface of the housing body 21. The recessed portion 26 is provided below the locking arm 22. The recessed portion 26 is a portion between the left and right side surfaces 27 and above the bottom surface 28. The bottom surface 28 of the recessed portion 26 is an opposing surface that is opposed to the locking arm 22. The bottom surface 28 of the recessed portion 26 is arranged at a position one level lower than the upper surfaces of the left and right end portions of the housing body 21. A bending space 29 for the locking arm 22 is formed between the bottom surface 28 of the recessed portion 26 and the locking arm 22. A recessed portion 31 is provided on the bottom surface 28 of the recessed portion 26. The recessed portion 31 will be described in detail later.

[0018] like Figure 2 As shown, the lock arm 22 includes a base end portion 32, an arm portion 33, and an operating portion 34. The base end portion 32 stands up from the front end portion of the bottom surface 28 of the recessed portion 26. The arm portion 33 extends rearward from the base end portion 32. The operating portion 34 is provided at the rear end portion of the arm portion 33. The lock arm 22 can be elastically deformed in the up-down direction with the base end portion 32 as a fulcrum.

[0019] The arm portion 33 has a locking protrusion 35. The locking protrusion 35 protrudes upward from the front and rear middle portion of the arm portion 33. The locking protrusion 35 is locked with the locking portion 13 of the counterpart connector 11. An entry portion 36 is formed below the locking protrusion 35. When the detection member 50 is located at the second position, the restriction protrusion 56 enters the entry portion 36. A locking hole 37 is formed behind the locking protrusion 35 in the arm portion 33.

[0020] The operating portion 34 is arranged at a position higher than the locking protrusion 35. Figure 4 As shown, the operating portion 34 is in the shape of a square plate extending over the entire width of the lock arm 22 .

[0021] like Figure 4 As shown, the housing 20 has a first locking protrusion 38 and a second locking protrusion 39. The first locking protrusion 38 has a function of keeping the detection member 50 at a first position relative to the housing 20. The second locking protrusion 39 has a function of keeping the detection member 50 at a second position relative to the housing 20.

[0022] like Figure 4 As shown, the first locking protrusion 38 is provided on the operating portion 34 of the locking arm 22. The first locking protrusion 38 is arranged behind the second locking protrusion 39. The first locking protrusion 38 protrudes outward from the left side and the right side of the operating portion 34 in the left-right direction. Figure 5 As shown, the first locking protrusion 38 is located above the second locking protrusion 39 .

[0023] like Figure 4 As shown, the second locking protrusion 39 is provided on the housing body 21. The second locking protrusion 39 protrudes from the left and right side surfaces 27 of the recessed portion 26 inward in the left-right direction.

[0024] like Figure 2 As shown, the detection member 50 is mounted on the locking arm 22 in a manner that it can move from a first position to a second position. Figure 2 In FIG. 1 , the detection member 50 disposed at the first position is indicated by a two-dot chain line. When the detection member 50 is mated with the mating connector 11, movement from the first position to the second position is allowed.

[0025] The detection member 50 is made of synthetic resin, such as Figure 6 and Figure 7 As shown in FIG. 1 , the rear end of the base 51 is provided with an extension portion 52, and the side surfaces are provided with a first stop portion 53 and a second stop portion 54. The left and right surfaces of the base 51 are provided with protrusions 55 protruding outward. By pressing the rear surface of the base 51 forward, the detection member 50 moves from the first position to the second position. Figure 7 As shown, the base 51 has a cutout 58, and a vertical wall 45 described later can enter the cutout 58 from below. The cutout 58 is provided on the inner side of the left and right second locking portions 54 in the left and right direction.

[0026] The extension portion 52 extends forward from the left-right center of the base portion 51. The extension portion 52 can be elastically deformed in the vertical direction with the rear end side as a fulcrum. A limiting protrusion 56 is provided at the front end of the extension portion 52. When the detection member 50 is arranged in the second position, the limiting protrusion 56 enters the entry portion 36 (refer to Figure 2 ).

[0027] like Figure 6 As shown, the first stopper 53 and the second stopper 54 extend forward from the left and right ends of the base 51. The front end of the second stopper 54 is located forward of the front end of the first stopper 53. The second stopper 54 is arranged one level outside the first stopper 53 in the left-right direction.

[0028] like Figure 8 As shown, when the detection member 50 is mounted on the lock arm 22, the left and right first stopper portions 53 are in contact with or close to the left and right surfaces of the operating portion 34. When the detection member 50 is mounted on the lock arm 22, the left and right second stopper portions 54 are in contact with or close to the left and right side surfaces 27 of the recessed portion 26.

[0029] like Figure 8 and Fig. 9 As shown, when the detection member 50 is mounted on the lock arm 22, the upper surfaces of the first stopper 53 and the protrusion 55 are arranged at substantially the same height as the upper surface of the operating portion 34 of the lock arm 22. The upper surface of the first stopper 53 and the upper surface of the protrusion 55 can abut against a finger together with the upper surface of the operating portion 34.

[0030] like Fig.10 As shown, when viewed from the left and right directions, the first stopper 53 and the second stopper 54 are rectangular frame-shaped. A rectangular stopper hole 57 is formed in the first stopper 53 and the second stopper 54 and penetrates in the left and right directions. The first stopper 53 and the second stopper 54 can be elastically deformed in the left and right directions with the rear end side as a fulcrum.

[0031] Before the connector 10 and the mating connector 11 are mated, Fig.12 As shown, the detection member 50 is inserted into the flexure space 29 of the housing 20 from the rear and assembled in the first position. During the assembly process, the left and right first stop portions 53 contact the first stop protrusions 38 and elastically deform outward in the left and right directions. When the detection member 50 reaches the first position, as shown in FIG. Fig.10 As shown, the front end of the first stop portion 53 passes over the first stop protrusion 38, is displaced inward in the left-right direction by elastic force, and is stopped by the first stop protrusion 38. As a result, the movement of the detection member 50 to the rear is restricted. When the detection member 50 is configured in the first position, the front end of the second stop portion 54 and the rear surface of the second stop protrusion 39 are staggered in the front-to-back direction. In addition, in the first position, the limiting protrusion 56 of the extension portion 52 enters the locking hole 37 and is located behind the locking protrusion 35. As a result, the movement of the detection member 50 to the front is restricted. In this way, the detection member 50 is maintained in the first position.

[0032] When the connector 10 and the mating connector 11 are in the mating state, as shown in FIG. Figure 2 As shown in FIG. 1 , when the detection member 50 is pressed from the rear, it moves from the first position to the second position. When the detection member 50 is configured in the second position, as shown in FIG. Fig.11 As shown, the second locking protrusion 39 is embedded in the locking hole 57 of the second locking portion 54. As a result, the movement of the detection member 50 to the rear is restricted. When the detection member 50 is arranged in the second position, the limiting protrusion 56 enters the entry portion 36. Because there is no space in front of the entry portion 36, the movement of the detection member 50 to the front is restricted. In this way, the detection member 50 is maintained in the second position.

[0033] like Fig.13As shown, the housing 20 has a recess 31, and when the detection member 50 is arranged in the first position, when the lock arm 22 is elastically deformed during the mating process with the mating connector 11, the detection member 50 enters the recess 31. The recess 31 is a portion that is recessed downward from the bottom surface 28 of the recess 26. The recess 31 is formed in the range from the bottom surface 28 of the recess 26 to the lower surface of the housing 20 in the vertical direction of the housing 20. The formation range of the recess 31 is limited to the formation range of the stopper mounting portion 25 in the vertical direction. The recess 31 has a front wall 43 and a bottom wall 44. An inclined surface 46 is provided on the upper portion of the front wall 43 of the recess 31.

[0034] like Figure 5 As shown, the recess 31 has a first recess 41 located in the center in the left-right direction and second recesses 42 located on the left and right sides of the first recess 41. A vertical wall 45 is provided between the first recess 41 and the second recess 42. The upper surfaces of the left and right vertical walls 45 constitute the bottom surface 28 of the recess 26.

[0035] like Fig.14 As shown, the extension 52 of the detection member 50 enters the first recess 41. The extension 52 of the detection member 50 entering the first recess 41 contacts or approaches the upper end of the front wall 43, and the lower end of the detection member 50 contacts or approaches the bottom wall 44. In the first recess 41, the bottom wall 44 continues to the rear end of the housing 20.

[0036] like Figure 5 As shown, the second recess 42 is formed between the standing wall 45 and the wall surface 47 of the housing body 21. The wall surface 47 of the housing body 21 is continuous downward from the left and right side surfaces 27 of the recess 26. In other words, the upper portion of the wall surface 47 of the housing body 21 constitutes the left and right side surfaces 27 of the recess 26.

[0037] like Fig.13 As shown, a part of the second locking portion 54 enters the second recess 42. In the second recess 42, the bottom wall 44 is located forward of the rear end of the housing 20. When the lock arm 22 is elastically deformed, the base 51 enters the open portion behind the bottom wall 44.

[0038] like Fig.13 As shown, the recess 31 has a movement limiting surface 48, and the movement limiting surface 48 is located in front of the detection member 50 in the state of entering the recess 31 in the moving direction from the first position to the second position. The movement limiting surface 48 is provided at the lower part of the front wall 43 of the second recess 42. The movement limiting surface 48 is perpendicular to the moving direction (front-rear direction) of the detection member 50.

[0039] Next, an example of the operation of completely fitting the connector 10 and the mating connector 11 will be described. Fig.12As shown in FIG. 1 , the housing 20 is inserted into the cover 12 of the other connector 11 and is engaged with the other connector 11. When the housing 20 is engaged with the other connector 11, as shown in FIG. Fig.13 and Fig.14 As shown, the locking protrusion 35 contacts the locking portion 13, and the locking arm 22 elastically deforms downward (toward the flexure space 29). In conjunction with the elastic deformation of the locking arm 22, the detection member 50 also shifts downward. The detection member 50 enters the recess 31. Specifically, the extension portion 52 enters the first recess 41, and the left and right second stop portions 54 respectively enter the left and right second recesses 42. In addition, the vertical wall 45 enters the notch 58.

[0040] When the detection member 50 enters the recessed portion 31, the second stopper 54 is located behind the moving direction of the movement limiting surface 48. When the detection member 50 is pressed forward in this state, the lower end of the front surface of the second stopper 54 contacts the movement limiting surface 48. In addition, the limiting protrusion 56 contacts the locking protrusion 35. Thus, the movement of the detection member 50 from the first position to the second position is restricted.

[0041] Then, when mating with the other connector 11, as shown in FIG. Figure 2 As shown, the connector 10 is inserted into the cover 12 of the other connector 11 at a regular depth, and the connector 10 and the other connector 11 are in a mating state. At this time, the detection member 50 is configured in the first position shown by the double-dotted line. The locking arm 22 elastically recovers when mating with the other connector 11, and the locking protrusion 35 shifts upward and is locked with the locking portion 13. As a result, the connector 10 and the other connector 11 are maintained in a mating state. By shifting the locking protrusion 35 upward, the detection member 50 is in a state that can move to the second position.

[0042] At this time, when the detection member 50 is pressed forward, Fig.11 As shown in FIG. 1 , the front end of the second stopper 54 elastically passes over the second stopper protrusion 39, and the detection member 50 reaches the second position. The second stopper protrusion 39 is embedded in the stopper hole 57 of the second stopper 54, and the movement of the detection member 50 to the first position is restricted. Figure 2 As shown, the restricting protrusion 56 enters the entry portion 36. As a result, the downward elastic deformation of the lock arm 22 is restricted. Through the above, the operation of fitting the connector 10 and the mating connector 11 is completed.

[0043] Next, an example of the operation of removing the mating connector 10 and the mating connector 11 is described. First, the detection member 50 is moved from the second position to the first position. Specifically, the left and right protrusions 55 of the detection member 50 are pinched with fingers and pulled backward to move the detection member 50 backward. In this way, the locking arm 22 can be released.

[0044] Next, the operating portion 34 of the locking arm 22 is pressed downward to elastically deform the locking arm 22 downward. At this time, since the finger can be pressed against the wide surface formed by the upper surface of the operating portion 34 of the locking arm 22, the upper surfaces of the left and right first stop portions 53, and the upper surface of the protrusion 55, the pressing operation of the operating portion 34 can be easily performed. In conjunction with the elastic deformation of the locking arm 22, the detection member 50 is also displaced downward, and the detection member 50 enters the recess 31. In the case where the recess 31 is not provided, it is necessary to raise the height position of the locking arm 22, but by providing the recess 31, the height position of the locking arm 22 can also be not raised. Thus, even if the height position of the locking arm 22 is not raised, the detection member 50 can be prevented from hindering the downward displacement of the locking arm 22. By the locking arm 22 being displaced downward, the locking protrusion 35 is displaced downward, and the connector 10 can move backward. The connector 10 is pulled backward to be removed from the counterpart connector 11. Through the above, the work of removing the connector 10 and the mating connector 11 in the completely fitted state is completed.

[0045] Next, the function and effect of the embodiment constructed as described above are described. The connector 10 includes a housing 20, an elastically deformable locking arm 22, and a detection member 50. The locking arm 22 is provided on the housing 20. The locking arm 22 is locked with the locking portion 13 provided on the other connector 11 in the mating state with the other connector 11. The detection member 50 is mounted on the locking arm 22 in a manner that it can move between a first position and a second position. The detection member 50 is allowed to move from the first position to the second position in the mating state. The housing 20 has a bottom surface 28 of a recessed portion 26, and the bottom surface 28 is opposite to the locking arm 22, and a flexure space 29 is formed between the locking arm 22. The bottom surface 28 of the recessed portion 26 has a recess 31, and when the detection member 50 is arranged in the first position, when the locking arm 22 is elastically deformed during the mating process with the other connector 11, the detection member 50 enters the recess 31.

[0046] According to this structure, when the connector 10 in the mating state is separated, the detection member 50 is moved from the second position to the first position to elastically deform the lock arm 22. At this time, the detection member 50 arranged in the first position is displaced along with the elastic deformation of the lock arm 22 and enters the concave portion 31 of the opposite surface. Therefore, the detection member 50 can prevent the lock arm 22 from being difficult to elastically deform, and the lock arm 22 can be easily unlocked.

[0047] The recess 31 has a movement limiting surface 48. The movement limiting surface 48 is located in front of the detection member 50 in the state of entering the recess 31 in the moving direction from the first position to the second position. According to this structure, when the locking arm 22 is elastically deformed, even if the detection member 50 is to be pressed from the first position to the second position, the detection member 50 abuts against the movement limiting surface 48 and cannot move. Because the movement limiting surface 48 that limits the movement of the detection member 50 from the first position to the second position is provided in the recess 31, the housing 20 can be miniaturized compared to the case where the movement limiting surface 48 is provided at a position different from the recess 31.

[0048] The detection member 50 has a second stopper 54. The second stopper 54 is stopped with the housing 20 at the second position. When the detection member 50 enters the recess 31, the second stopper 54 is located behind the moving direction of the movement limiting surface 48. According to this structure, the second stopper 54 has the function of being stopped with the housing 20 at the second position, and the function of contacting with the movement limiting surface 48 to prevent the detection member 50 from moving from the first position to the second position. Therefore, compared with the case where these functions are provided at different positions, the detection member 50 can be miniaturized.

[0049] The housing 20 is provided with a stopper mounting portion 25 communicating with the terminal storage chamber 23. The formation range of the recess 31 in the vertical direction of the housing 20 is limited to the formation range of the stopper mounting portion 25 in the vertical direction of the housing 20. According to this structure, in the housing 20 having the stopper mounting portion 25, the recess 31 can be formed without increasing the vertical dimension, so that the housing 20 can be prevented from being enlarged.

[0050] [Other embodiments of the present invention] The embodiments disclosed this time should be considered as illustrative in all aspects and not restrictive. In the above-described embodiment, the movement restricting surface 48 is provided in the second recessed portion 42 . However, as another embodiment, the movement restricting surface may be provided in the first recessed portion 41 . In the above-described embodiment, the movement restricting surface 48 is provided in the recessed portion 31 . However, as another embodiment, the movement restricting surface may be provided at a location other than the recessed portion. In the above embodiment, the second locking portion 54 of the detection member 50 contacts the movement restricting surface 48 . However, in another embodiment, a portion of the detection member other than the second locking portion may contact the movement restricting surface. In the above embodiment, the formation range of the recessed portion 31 in the vertical direction of the housing 20 is limited to the formation range of the stopper mounting portion 25 in the vertical direction of the housing 20, but as other embodiments, the formation range of the recessed portion may not be limited to the formation range of the stopper mounting portion 25. In addition, the connector may not have a stopper. In the above embodiment, the second locking portion 54 is locked with the housing 20 at the second position, but as another embodiment, the second locking portion may be locked with the lock arm at the second position. In this case, the second locking protrusion may be provided on the lock arm. Description of Reference Numerals
