Definitions
- the present invention relates to a connector and a connector assembly provided with a connection detecting function.
- a known connector provided with a connection detecting function is constructed such that one of two connector housings connectable with each other includes a lock arm for locking the two connector housings in their connected state, a slider displaceable between an initial position and a detecting position, and spring members for accumulating spring forces for biasing the slider toward the detecting position as the connection of the two connector housings progresses (for example, Japanese Unexamined Patent Publication No. H10-50408).
- the lock arm is resiliently deformed to hold the slider at the initial position.
- the lock arm resiliently returns to permit a displacement of the slider to a connecting position, whereby the slider is displaced to the detecting position by the biasing forces of the spring members. If the connecting operation should be completed with the two connector housings partly connected, the two connector housings are separated by the biasing forces of the spring members.
- the spring members are provided at the opposite left and right sides of the lock arm in the above connector, it is necessary to ensure spaces exclusively used to arrange the spring members. Thus, it has been unavoidable to enlarge the connector as a whole.
- the present invention was developed in view of the above problem and an object thereof is to miniaturize a connector.
- a connector comprising:
- the area of the space between the connection circumferential surface of the connector housing and the lock arm where the receptacle does not enter is a dead space. Since the spring member is at least partly accommodated in the dead space in the present invention, it is not necessary to provide a space exclusively-used to arrange the spring member and the connector can be miniaturized as a whole.
- the lock arm when positioned in the first position, the lock arm is resiliently deformed.
- the lock arm when positioned in the second position, the lock arm is resiliently at least partly restored.
- a connector comprising:

Since the spring member is accommodated in the dead space in the above embodiment, it is not necessary to provide a space exclusively used to arrange the spring member and the connector can be miniaturized as a whole.
- the lock arm can undergo a seesaw-like resilient deformation.
- an area of the lock arm corresponding to the accommodation space is displaced in a direction toward the connection circumferential surface of the connector housing in the process of connecting the two connector housings.
- an escaping portion capable of accommodating a part of the biasing member is formed in a surface of the lock arm at least partly substantially facing the accommodation space.
- the lock arm can undergo a seesaw-like resilient deformation, an area of the lock arm corresponding to the accommodation space is displaced in a direction toward the connection circumferential surface of the first connector housing in the process of connecting the two connector housings, and an escaping portion capable of accommodating a part of the spring member is formed in a surface of the lock arm facing the accommodation space.
- the escaping portion capable of accommodating a part of the spring member is formed in the surface of the lock arm facing the accommodation space, a large volume of the accommodation space can be ensured even if the accommodation space becomes smaller as the lock arm is resiliently deformed. Therefore, the spring member can be enlarged, which can, in turn, improve the reliability of a connection detecting function.
- the movable member is held at the initial position by a semi-locking construction to prevent the movable member from moving towards or to the detecting position unless a specified for or grater is applied to the movable member.

Abstract
Description
- The present invention relates to a connector and a connector assembly provided with a connection detecting function.
- A known connector provided with a connection detecting function is constructed such that one of two connector housings connectable with each other includes a lock arm for locking the two connector housings in their connected state, a slider displaceable between an initial position and a detecting position, and spring members for accumulating spring forces for biasing the slider toward the detecting position as the connection of the two connector housings progresses (for example, Japanese Unexamined Patent Publication No. H10-50408).
- During the connection of the two connector housings, the lock arm is resiliently deformed to hold the slider at the initial position. When the two connector housings are properly connected, the lock arm resiliently returns to permit a displacement of the slider to a connecting position, whereby the slider is displaced to the detecting position by the biasing forces of the spring members. If the connecting operation should be completed with the two connector housings partly connected, the two connector housings are separated by the biasing forces of the spring members.
- Since the spring members are provided at the opposite left and right sides of the lock arm in the above connector, it is necessary to ensure spaces exclusively used to arrange the spring members. Thus, it has been unavoidable to enlarge the connector as a whole.
- The present invention was developed in view of the above problem and an object thereof is to miniaturize a connector.
- This object is solved according to the invention by the features of the independent claims. Preferred embodiments of the invention are subject of the dependent claims.
- According to the invention, there is provided a connector, comprising:
- a connector housing connectable with a mating connector housing of a mating connector,
- a lock arm provided in or on the connector housing and engageable with the mating connector housing to lock the two connector housings in their properly connected state,
- a movable member provided in or on the connector housing and displaceable between an initial position and a detecting position,
- at least one biasing member provided in or on the connector housing for accumulating-a biasing force to bias the movable member toward the detecting position as the connection of the two connector housings progresses,

- out of the space between the connection circumferential surface of the connector housing and the lock arm, an area where the receptacle does not enter serves as an accommodation space for at least partly accommodating the biasing member.
- The area of the space between the connection circumferential surface of the connector housing and the lock arm where the receptacle does not enter is a dead space. Since the spring member is at least partly accommodated in the dead space in the present invention, it is not necessary to provide a space exclusively-used to arrange the spring member and the connector can be miniaturized as a whole.
- According to a preferred embodiment of the invention, when positioned in the first position, the lock arm is resiliently deformed.
- Preferably, when positioned in the second position, the lock arm is resiliently at least partly restored.
- According to a preferred embodiment of the invention, there is further provided a connector, comprising:

wherein: - the lock arm is resiliently deformed to hold the slider at the initial position while the two connector housings are being connected,
- the lock arm is resiliently restored to permit a displacement of the slider to a connecting position and the slider is displaced to the detecting position by the biasing force of the spring member when the two connector housings reach the properly connected state,
- a space for permitting the entrance of a receptacle of the second connector housing is defined between a connection circumferential surface of the first connector housing and the lock arm, and
- out of the space between the connection circumferential surface of the first connector housing and the lock arm, an area where the receptacle does not enter serves as an accommodation space for accommodating the spring member.
- The area of the space between the connection circumferential surface of the first connector housing and the lock arm where the receptacle does not enter is a dead space. Since the spring member is accommodated in the dead space in the above embodiment, it is not necessary to provide a space exclusively used to arrange the spring member and the connector can be miniaturized as a whole.
- Preferably, the lock arm can undergo a seesaw-like resilient deformation.
- Further preferably, an area of the lock arm corresponding to the accommodation space is displaced in a direction toward the connection circumferential surface of the connector housing in the process of connecting the two connector housings.
- Still further preferably, an escaping portion capable of accommodating a part of the biasing member is formed in a surface of the lock arm at least partly substantially facing the accommodation space.
- Most preferably, the lock arm can undergo a seesaw-like resilient deformation,
an area of the lock arm corresponding to the accommodation space is displaced in a direction toward the connection circumferential surface of the first connector housing in the process of connecting the two connector housings, and
an escaping portion capable of accommodating a part of the spring member is formed in a surface of the lock arm facing the accommodation space. - Since the escaping portion capable of accommodating a part of the spring member is formed in the surface of the lock arm facing the accommodation space, a large volume of the accommodation space can be ensured even if the accommodation space becomes smaller as the lock arm is resiliently deformed. Therefore, the spring member can be enlarged, which can, in turn, improve the reliability of a connection detecting function.

Thelock arm 15 preferably is, as a whole, in the form of a long plate extending substantially in forward and backward directions (directions substantially parallel with a connecting direction CD of the twoconnector housings 10, 60) and alock projection 16 is formed to project downward (direction substantially toward the connectioncircumferential surface 14 of the housing main body 11) from or near the front end. At an intermediate position of thelock arm 15 preferably slightly behind its longitudinal center, one or more, preferably a pair of lateral (left and right)leg portions 17 extend downward (direction substantially toward the connectioncircumferential surface 14 of the housing main body 11) from the (preferably opposite) lateral (left and/or right) edge(s). The bottom ends of theleg portions 17 are substantially continuous with the connectioncircumferential surface 14. In other words, thelock arm 15 is supported on the connectioncircumferential surface 14 of the housingmain body 11 at bothleg portions 17, and a clearance for permitting the at least partial entrance of thereceptacle 62 is defined between the connectioncircumferential surface 14 and the inward (lower) surface of thelock arm 15. Although being in such a posture substantially parallel with the connection circumferential surface 14 (substantially parallel with the connecting direction CD of the twoconnector housings 10, 60) in a free state, the lock arm undergoes such a resilient displacement as to take a posture inclined upward toward the front (or away from the housing main body 11) with theleg portions 17 as supporting, points in the connecting process. In other words, thelock arm 15 is capable of undergoing seesaw-like displacements. - The
receptacle 62 is at least partly inserted only in an area of the clearance between the lock-arm 15 and the connectioncircumferential surface 14 before theleg portions 17, and an area of this clearance behind theleg portions 17 serves as anaccommodation space 18 for at least partly accommodating the spring member 50 (as the preferred biasing member) to be described later. In an area of the lower surface (surface facing the connection circumferential surface 14) of thelock arm 15 corresponding to theaccommodation space 18 behind theleg portions 17 is formed an escapingportion 19 preferably arcuate when viewed in forward and backward directions (see e.g. FIG. 7). The curvature of the arc of this escapingportion 19 preferably is substantially equal to that of the outer circumference of thespring member 50. - A first area (preferably a substantially upper-half area) of the tubular
fitting portion 12 serves as a coveringportion 20 for at least partly covering thelock arm 15, theslider 30 and/or thespring member 50 from outside (from above, left and/or right). A space above thelock arm 15 in the inner space of the coveringportion 20 serves as aslider space 21 for at least partly accommodating theslider 30. A substantiallystraight guide groove 22 extending substantially in forward and backward directions (or substantially in the connecting direction CD) is formed in each of the inner surfaces of the lateral (left and right) walls of theslider space 21, and a pair of lateral (left and right) receivingportions 23 are formed on the outer (ceiling) surface of theslider space 21. Afront wall 24 is formed at the front end of theslider space 21, and the rear end of the upper plate forming theslider space 21 serves as a front-stop portion 25. Further, one or more, preferably a pair ofsemi-locking projections 26 are formed at the lateral (left and/or right) edge(s) of the connectioncircumferential surface 14. Thesemi-locking projections 26 are formed such that the locking function is released when a force exceeding a specified (predetermined or predeterminable) force is applied thereto. - The
slider 30 is made e.g. of a synthetic resin and includes amain portion 31 preferably substantially in the form of a rectangular plate narrow and long in forward and backward directions (or substantially in the connecting direction CD) as a whole, and aspring holding portion 32 substantially continuous with the rear end of themain portion 31. Themain portion 31 is at least partly mounted or mountable into thefirst connector housing 10 with the plate surface thereof oriented in a direction substantially parallel with the lock arm 15 (horizontal direction or substantially parallel to the connecting direction CD). One or more, preferably a pair ofguide ribs 33 narrow and long substantially in forward and backward directions are formed on the (preferably opposite) lateral (left and/or right) surface(s) of themain portion 31; one or more, preferably a pair of lateral (left and/or right) retainingprojections 34 are formed on the lateral (upper) surface of themain portion 31; and adisplacement restricting portion 35 projecting substantially inward or downward is formed at or near the front end of themain portion 31. An unlockingportion 36 capable of undergoing such a displacement as to resiliently incline with respect to themain portion 31 is formed at or near the rear end of themain portion 31. - The
spring holding portion 32 includes one or more, preferably a pair ofthick side walls 37 extending inward or downward from or near the rear end of themain portion 31, aframe portion 38 preferably substantially U-shaped in front view and extending further forward from the front ends of theopposite side walls 37, and arear wall 39 connecting the rear ends of theside walls 37. A space having an open bottom end and surrounded by theopposite side walls 37, theframe portion 38 and therear wall 39 serves as aspring accommodating portion 40 for accommodating thespring member 50. Thespring accommodating portion 40 is open at lateral (upper and bottom) sides, and the inner surfaces of the left and right walls preferably have the substantially same curvature as the arcuate escapingportion 19 of thelock arm 15 and are substantially concentric with the escapingportion 19 with theslider 30 assembled into thefirst connector housing 10. A penetratingspace 41 penetrating substantially in forward and backward directions-(or substantially in the connecting direction CD) is formed between thespring accommodating portion 40 and the unlockingportion 36. Thespring holding portion 32 is also formed with one or more, preferably a pair of lateral (left and/or right)semi-locking pieces 42 in the form of cantilevers extending forward. - At least one
spring member 50 and at least onespring receiving body 51 are at least partly accommodated in thespring accommodating portion 40. Thespring member 50 preferably is a compression coil spring and is brought or bringable into contact with therear wall 39 from front with the longitudinal axis thereof oriented substantially along forward and backward directions (directions substantially parallel with the connecting direction CD of the twoconnector housings spring receiving body 51 is comprised of a fitting/holdingportion 52 connected to, preferably at least partly fitted into a front end portion of thespring member 50 from front, awidened wall 53 formed at the front end of the fitting/holdingportion 52 and having a larger outer diameter than the fitting/holdingportion 52, and apressable projection 54 projecting substantially forward from a lateral portion, preferably a substantially upper-half area, of the front end surface of the widenedwall 53. An area of the front surface of the widenedwall 53 where thepressable projection 54 is not formed serves as acontact surface 55 which is brought or bringable substantially into contact with afront wall 43 of theframe portion 38 substantially from behind. At this time, thespring member 50 preferably is resiliently compressed along longitudinal direction. It should be understood that even though in the present embodiment thespring member 50 as the preferred biasing member is a coil spring, any other biasing member such as a resilient block (e.g. made of rubber or the like) may be used according to the invention. - The
second connector housing 60 is made e.g. of a synthetic resin and includes a substantially block-shapedterminal holding portion 61 for holding one or more maleterminal fittings 65 and thereceptade 62 projecting substantially forward or along the connecting direction CD from theterminal holding portion 61. One ormore tabs 66 at the leading ends of the respective male terminal fitting(s) 65 project forward from the front end surface of theterminal holding portion 61 and at least partly surrounded by thereceptacle 62. The (preferably lateral or upper end of the) front edge of thereceptacle 62 serves as apressing portion 63, and alock protrusion 64 is formed on the (preferably upper) outer surface of thereceptacle 62. Next, functions of this embodiment are described. - The
slider 30 preferably having thespring member 50 and thespring receiving body 51 assembled therewith is assembled into theslider space 21 preferably substantially from behind thefirst connector housing 10. Upon assembling, the one ormore guide ribs 33 are at least partly fitted into the respective one ormore guide grooves 22 while a part of theslider 30 behind theleg portions 17 of thelock arm 15 is inserted into the penetratingspace 41. When theslider 30 is pushed to a front-most initial position, the front end surface of the unlockingportion 36 comes substantially into abutment against the front-stop portion 25 of the tubularfitting portion 12 to stop theslider 30 at its front end position, and thesemi-locking pieces 42 are engaged with thesemi-locking projections 26 to prevent theslider 30 from returning backward. As a result, theslider 30 is held substantially at the initial position IP (FIG. 2). - With the slider held at the initial position IP, the
spring accommodating portion 40, thespring member 50 and thespring receiving body 51 are or can be at least partly accommodated into theaccommodation space 18, wherein the upper opening of thespring accommodating portion 40 is at least partly covered by the area of thelock arm 15 where the escapingportion 19 is formed and the bottom opening thereof is at least partly closed by the area of the outer circumferential surface of the housing main-body 11 located behind thefront retainer 13. While thelock arm 15 is substantially not resiliently deformed, a clearance for permitting the inclining displacement of thelock arm 15 for unlocking is defined between the lower surface of the escapingportion 19 and the outer (upper) surface of thespring member 50. - Since the
lock arm 15 is located at a position lower or more inwardly than themain portion 31 of theslider 30 while thelock arm 15 is substantially not resiliently deformed, theslider 30 can be slid backward (toward the detecting position). Similarly, while thelock arm 15 is substantially not resiliently deformed, the lower surface of the unlockingportion 36 of theslider 30 is in contact with the outer (upper) surface of the rear end of thelock arm 15 or substantially opposed (or facing) thereto with a slight clearance therebetween. - In this state, the first and
second connector housings receptacle 62 of thesecond connector housing 60 is at least partly fitted into the tubular space S of thefirst connector housing 10. As thereceptacle 62 is fitted, thepressing portion 63 at the front end of thereceptacle 62 comes substantially into contact with the front end surface of thepressable projection 54 of thespring receiving body 51 as shown in FIG. 2. Preferably almost simultaneously, thelock arm 15 is inclined or deflected to bring its front part outward or upward (or away from the thereceptacle 62 at least partly inserted into the housing main body 11) as thelock projection 16 moves onto the lock protrusion 64 (see FIG. 3), whereby the front end of thelock arm 15 comes substantially into engagement with thedisplacement preventing portion 35 at the front end of theslider 30 substantially from inside and/or behind. This engagement temporarily locks or prevents theslider 30 from sliding backward (toward the detecting position DP). At this time, a part (upper end) of thespring member 50 enters the escapingportion 19. - Thereafter, as the connection of the two
connector housings spring receiving body 51 pushed by thereceptacle 62 moves backward with theslider 30 kept prevented from displacing backward by thelock arm 15 as shown in FIG. 3. Accordingly, thespring member 50 is resiliently compressed and such a biasing force as to extend thespring member 50 in forward and backward directions (or substantially along the connecting direction CD) is accumulated in thespring member 50. This biasing force acts as a force to push thesecond connector housing 60 backward (separating direction) with respect to thefirst connector housing 10 and, simultaneously, acts as a force to press theslider 30 toward the rear side of the first connector housing 10 (toward the detecting position DP) with respect to the twoconnector housings - When the two
connector housings lock projection 16 passes thelock protrusion 64 as shown in FIG. 4, whereby thelock arm 15 is resiliently at least partly restored to engage thelock projection 16 with thelock protrusion 64. As a result, the twoconnector housings lock arm 15 is resiliently at least partly restored, thelock arm 15 is disengaged from thedisplacement preventing portion 35. Then, thesemi-locking pieces 42 and thesemi-locking projections 26 are disengaged from each other by the biasing force accumulated in the spring member 50 (which exceeds the specified (predetermined or predeterminable) force to be applied to thesemi-locking pieces 42 to release their locking function), whereby theslider 30 is slid backward to reach the detecting position DP (see FIG. 4). That the twoconnector housings slider 30 to the detecting position DP. - Different from the above, if the connecting operation of the two
connector housings spring receiving body 51 pushes thereceptacle 62 back by the biasing force accumulated in the resiliently compressedspring member 50 as shown in FIG. 3, whereby the twoconnector housings connector housings connector housings - Upon separating the two
connector housings slider 30 is slid to the initial position IP in front while resiliently compressing thespring member 50 and the unlockingportion 36 is pressed down at this position. Then, the rear end of thelock arm 15 is pressed down by the unlockingportion 36 and thelock arm 15 is inclined to disengage thelock projection 16 from thelock protrusion 64. Upon the disengagement of thelock projection 16 from thelock protrusion 64, the twoconnector housings spring member 50 as theslider 30 is slid to the initial position IP. - As described above, according to this embodiment, the space S for permitting the at least partial entrance of the
receptacle 62 of thesecond connector housing 60 is defined between the connectioncircumferential surface 14 of thefirst connector housing 10 and thelock arm 15 and, out of the space S between the connectioncircumferential surface 14 of thefirst connector housing 10 and thelock arm 15, the area where thereceptacle 62 does not enter serves as theaccommodation space 18 for at least partly accommodating thespring member 50. Thisaccommodation space 18 is a dead space because thereceptacle 62 does not enter. Since thespring member 50 is at least partly accommodated in the dead space in this way, it is not necessary to provide a space exclusively used to arrange thespring member 50. As a result, the connector can be miniaturized as a whole. - The
lock arm 15 can undergo a seesaw-like resilient deformation and the area of thelock arm 15 corresponding to theaccommodation space 18 is displaced in the direction toward the connectioncircumferential surface 14 of thefirst connector housing 10 in the process of connecting the twoconnector housings portion 19 for accommodating a part of thespring member 50 is formed in the surface of thelock arm 15 substantially facing theaccommodation space 18. Since the escapingportion 19 is formed in the surface of thelock arm 15 facing theaccommodation space 18 in this way, a large volume of theaccommodation space 18 can be advantageously ensured even if theaccommodation space 18 becomes smaller as thelock arm 15 is resiliently deformed. Therefore, thespring member 50 can be enlarged, which can, in turn, improve the reliability of the connection detecting function. - Accordingly, to miniaturize a connector, a space S for permitting the at least partial entrance of a
receptacle 62 of asecond connector housing 60 is defined between a connectioncircumferential surface 14 of afirst connector housing 10 and alock arm 15. Out of the space S between the connectioncircumferential surface 14 of thefirst connector housing 10 and thelock arm 15, an area (accommodation space 18) where thereceptacle 62 does not enter is a dead space S.A spring member 50 as a preferred biasing member is at least partly accommodated into this dead space S. Thus, it is not necessary to provide a space exclusively used to arrange thespring member 50 and a connector can be miniaturized as a whole. - The present invention is not limited to the above described and illustrated embodiment. For example, the following embodiments are also embraced by the technical scope of the present invention as defined by the claims. Beside the following embodiments, various changes can be made without departing from the scope and spirit of the present invention as defined by the claims.
- (1) Although only one spring member is provided in the foregoing embodiment, a plurality of spring members may be provided according to the present invention.
- (2) Although the area of the lock arm facing the accommodation space is locally recessed to form the escaping portion in the foregoing embodiment, such a locally recessed escaping portion may be not provided according to the present invention.
- (3) Although the escaping portion has an arcuate cross section in the foregoing embodiment, it may have an elliptic, oblong, rectangular, trapezoidal or triangular cross section other than the arcuate cross section.
