Description

The present disclosure relates to connectors.

Conventionally, in a connector for connecting an electric wire such as a cable to another electric wire, an electric device, an electronic device, or the like, there has been a need to prevent the electric wire, the electric device, the electronic device, etc. from coming off or coming off from the mating connector. It has a locking mechanism (see, for example, Patent Document 1).

FIG. 9 is a sectional view showing a conventional connector.

In the figure, reference numeral 811 denotes a connector housing integrally formed of synthetic resin, comprising a terminal accommodating portion 812 for accommodating a terminal 851 connected to the end of an electric wire, and a cylinder surrounding the terminal accommodating portion 812. 813. A terminal 851 inserted from behind is accommodated inside the terminal accommodating portion 812 , and a ring-shaped sealing member 881 is attached to the outer surface of the terminal accommodating portion 812 . A lock arm 831 is formed on the upper surface of the housing 811 . The lock arm 831 is connected to the terminal housing portion 812 by a support portion 832 in the vicinity of the center in the front-rear direction, and is swingable around the support portion 832 .

As shown in the figure, when the connector is mated with the mating connector, the mating housing 911 is inserted into the cylindrical portion 813, and the terminal receiving portion 812 is inserted into the mating housing 911. A rod-shaped mating terminal 951 contacts the terminal 851 accommodated inside the terminal accommodating portion 812 . The sealing member 881 is pressed by the mating housing 911 and the terminal accommodating portion 812 to seal the space between the mating housing 911 and the terminal accommodating portion 812, and the lock recess 835 formed near the tip of the lock arm 831 It engages with a lock protrusion 935 formed on the upper surface of the mating housing 911 .

As a result, the housing 811 and the counterpart housing 911 are locked to each other, so that the mated state of the connector and the counterpart connector is reliably maintained. Further, when it is necessary to release the engagement between the connector and the mating connector, the operator presses down the operating portion 837 formed on the upper surface near the rear end of the lock arm 831 with a finger or the like. The lock can be released by swinging the lock arm 831 to release the engagement between the lock concave portion 835 and the lock convex portion 935 .

JP-A-2005-26065

However, in the conventional connector, since the lock arm 831 is merely connected to the terminal accommodating portion 812 by the support portion 832, the function as a spring for elastically swinging the lock arm 831 is not sufficiently exhibited. . Therefore, the click feeling when locking the housing 811 and the mating housing 911 and the operability when releasing the lock are insufficient. In addition, the engagement between the lock concave portion 835 and the lock convex portion 935 was not necessarily maintained reliably, and the lockability was insufficient.

Here, by solving the above-mentioned conventional problems, the click feeling and operability when fitting with the mating connector are good, the lockability is high, and the mating with the mating connector can be reliably maintained. , to provide a highly reliable, inexpensive to manufacture, and highly durable connector.

For this purpose, the connector is provided with a housing made of an insulating material and mated with a mating connector having a mating housing made of an insulating material, the housing comprising a housing body and a mating locking member of the mating housing. and a support member connected to the housing body and supporting the lock member so as to be able to swing, wherein the lock member extends in the front-rear direction that is the mating direction with the mating connector. a pair of left and right girder members, an engaging portion that connects the front ends of the left and right girder members and can be engaged with the mating lock member, and an operation portion that connects the rear ends of the left and right girder members, The member includes a spring member having a substantially L-shaped shape when viewed from the side, and the spring member is a plate member extending from directly below one beam member to directly below the other beam member, a first elastic member whose proximal end is held by a holding member connected to the housing body, extends rearward, and has a lower surface which is an inclined surface rising rearward; and a pair of left and right second elastic members connected to both left and right ends of the free end of the elastic members, extending upward, and having upper ends connected to the respective beam members .

In still another connector, the thickness of each beam member is thicker than the thickness of the base end of the first elastic member.

In still another connector, the lock member further includes a projecting piece formed in the vicinity of its rear end and projecting outward in the width direction, and the housing includes upper projections formed on both left and right sides of the lock member. and a lower protrusion, and the vertical displacement of the rear end of the locking member is stopped when the protrusion comes into contact with the upper protrusion or the lower protrusion.

The mating connector 101 is connected to an electric wire, an electric device, an electronic device, or the like (not shown).

In this embodiment, expressions indicating directions such as up, down, left, right, front, and back used to describe the configuration and operation of each part included in the connector 1 and the mating connector 101 are absolute. It is not a physical but a relative one, and it is appropriate when each part included in the connector 1 and the mating connector 101 is in the posture shown in the figure. If it changes, it should be interpreted by changing it according to the change of posture.

The mating connector 101 is integrally formed of an insulating material such as synthetic resin. and a mating terminal 151 as a second terminal.

The mating housing 111 is a tubular member that extends in the fitting direction (X-axis direction) with the connector 1 as a whole, and includes a tubular side wall portion 111b and a base end of the side wall portion 111b ( It has a bottom plate portion 111c that closes the bottom surface of the cylinder at the end in the positive direction of the X axis. A space defined by the side wall portion 111b and the bottom plate portion 111c serves as a connector accommodating cavity 113 into which a portion of the connector 1 is inserted. The connector housing cavity 113 is a space that is open on the tip side (X-axis negative direction end side), and a plurality of (two in the example shown in the figure) mating terminals 151 are arranged therein. The mating terminal 151 is a linear rod-shaped member that protrudes from the bottom plate portion 111c toward the tip side.

A lock protrusion 135 as a mating lock member projecting upward is formed on the upper surface portion 111a, which is a portion of the side wall portion 111b positioned upward (in the positive direction of the Z axis). The lock projection 135 is formed on the tip side, and includes an inclined surface 135a inclined with respect to the X axis, a top surface 135b parallel to the X axis, and a rear end side (X axis positive direction end side) of the top surface 135b. and has a vertical surface 135c parallel to the Z-axis.

The connector 1 is integrally formed of an insulating material such as synthetic resin. and terminals (not shown).

The housing 11 includes a housing body 12 and a covering portion 13 that covers the housing body 12 .

The housing body 12 includes a base portion 12b near the rear end 11r of the housing 11, a fitting portion 12c extending forward from the base portion 12b and fitted with the mating housing 111 of the mating connector 101, the housing 11 It includes a body through-hole 21 extending from the front end 11f to the rear end 11r. Although the number of main body through-holes 21 may be any number, here, only the case of two corresponding to the number of electric wires 91 will be described. Each body through-hole 21 accommodates the tip portion of each electric wire 91 and the terminal connected to the tip of each electric wire 91 . A cylindrical sealing member 81 integrally formed of resin having flexibility like rubber such as silicone rubber is fitted around the fitting portion 12c.

The cover portion 13 includes a front top plate portion 13a that covers the upper portion of the fitting portion 12c, a pair of front side plate portions 13b that cover the left and right sides of the fitting portion 12c, and a front bottom plate that covers the lower portion of the fitting portion 12c. It includes a portion 13c, a pair of rear side plate portions 13d covering left and right sides above the base portion 12b, and a rear bottom plate portion 13e covering left and right sides and below the base portion 12b. Between the inner surface of the covering portion 13 and the outer surface of the fitting portion 12c, there is formed a fitting space portion 22, which is a space that opens at the front end 11f and extends rearward (in the negative direction of the X axis). ing. The fitting space portion 22 accommodates a portion on the tip side (X-axis negative direction end side) of the mating housing 111 when the connector 1 is mated with the mating connector 101 .

A lock member 31 is accommodated in a space above the base portion 12b defined by the rear side plate portion 13d from the space above the fitting portion 12c and the front top plate portion 13a. The lock member 31 is a member for locking the lock protrusion 135 as a mating lock member of the mating connector 101 when the connector 1 is mated with the mating connector 101, and functions together with the lock protrusion 135 as a lock mechanism. do.

The lock member 31 is a member capable of swinging in the XZ plane around a portion near the middle in the front-rear direction (X-axis direction), which is the fitting direction with the mating connector 101. When viewed from above, It is a member having a square frame shape. Specifically, the lock member 31 includes a pair of left and right girder members 33 extending in the front-rear direction as the mating direction with the mating connector 101, and left and right girder members 33 extending in the left-right direction (Y-axis direction). It has a front beam member 35 that connects the front ends of the members 33 and a rear beam member 37 that extends in the left-right direction and connects the rear ends of the left and right girder members 33 . The front beam member 35 is a portion that functions as an engaging portion that engages with the lock projection 135. The front beam member 35 is formed on the tip side (the end side in the positive direction of the X axis), and has a front surface 35a parallel to the Z axis and a front surface 35a parallel to the X axis. It has a parallel bottom surface 35b and a vertical surface 35c parallel to the Z axis and formed on the rear end side (X-axis negative direction end side) of the bottom surface 35b. In addition, the rear beam member 37 functions as an operation portion that is pushed down by an operator's finger or the like when unlocking.

Further, the lock member 31 has a support member 32 that connects the left and right beam members 33 and the upper surface portion 12a of the housing body 12 and supports the lock member 31 so as to swing. The support member 32 includes a first elastic member 32a, a pair of left and right second elastic members 32b connected to the free end (X-axis negative direction end) of the first elastic member 32a, and the first elastic member 32a. A holding member 32c connected to the base end (X-axis positive direction end) and a connecting member 32d connecting the lower surface of the holding member 32c to the upper surface portion 12a of the housing body 12 are included. The upper end of the second elastic member 32b is connected to the lower surface of the girder member 33. As shown in FIG. When force is applied from the left and right girder members 33 at the time of locking or unlocking, the first elastic member 32a and the second elastic member 32b are elastically deformed and function as spring members. In the example shown in FIG. 5, the boundary between the base end of the first elastic member 32a and the holding member 32c is indicated by a dotted line 32e, and the boundary between the left and right second elastic members 32b and the beam member 33 is indicated by a dotted line 32f. is represented.

The first elastic member 32a extends in the left-right direction from directly below the left beam member 33 to directly below the right beam member 33, and extends from the holding member 32c toward the rear end 11r of the housing 11. It is a plate member. As shown in FIG. 5, in the initial state where no external force is applied, the upper surface of the first elastic member 32a is parallel to the X-axis, but the lower surface of the first elastic member 32a rises as it goes rearward. It is an inclined surface like this. Therefore, the thickness (dimension in the Z-axis direction) of the first elastic member 32a is the thickest at the proximal end and gradually decreases toward the free end. As a result, the distribution of the stress generated inside the first elastic member 32a when the force from the left and right girder members 33 is applied to the free end via the second elastic member 32b is compared to the case where the wall thickness is constant. Then it becomes more uniform. In addition, since the lower surface of the first elastic member 32a is an inclined surface that rises as it goes rearward, the distance between the lower surface and the upper surface portion 12a of the housing body 12 becomes wider as it goes rearward. The downward movable range of the free end of the elastic member 32a is widened.

On the other hand, the holding member 32c has a thickness equal to or greater than that of the proximal end of the first elastic member 32a, and most of its lower surface is connected to the upper surface portion 12a of the housing body 12 via a connecting member 32d. Therefore, the first elastic member 32a has higher rigidity than the first elastic member 32a, and when a force is applied to the free end of the first elastic member 32a, the first elastic member 32a hardly deforms and does not function as a spring member. The connecting member 32d also has a large dimension in the front-rear direction (X-axis direction) and a small dimension in the vertical direction (Z-axis direction). It does not deform and does not function as a spring member.

On the other hand, the second elastic member 32b has substantially the same shape and dimensions as the connecting member 32d when viewed from the side, but as shown in FIGS. are connected to the left and right ends of the free ends of the , and the dimensions in the width direction (Y-axis direction) of each are considerably smaller than those of the connecting member 32d. When applied, it deforms elastically and functions as a spring member.

Thus, the support member 32 includes a first elastic member 32a and a second elastic member 32b that function as spring members. As shown in FIG. 5, when viewed from the side, the spring member extends from the dotted line 32e to the dotted line 32f, that is, from the proximal end of the first elastic member 32a to the upper end of the second elastic member 32b. Since it has a letter-like shape, the spring length is long. Therefore, the deformation range of the spring member is wide, and it can be deformed flexibly. As a result, the pair of left and right girder members 33 swing in the XZ plane around the portions represented by the dotted lines 32e and 32f, which are both ends of the spring member having a substantially L shape, as fulcrums. can be done.

The thickness of the girder member 33 at the boundary between A and the second elastic member 32b indicated by the dotted line 32f is When the thickness (dimension in the Z-axis direction) is B, A<B is desirable, and 2A<B is more desirable. By defining the relationship between the thickness of the proximal end of the first elastic member 32a and the thickness of the girder member 33 at the boundary between the second elastic member 32b in this manner, the first elastic member 32a can be locked or unlocked. The member 32a and the second elastic member 32b function appropriately as spring members, and the beam member 33 can swing smoothly with both ends of the spring members as fulcrums.

A projecting piece 38 projecting outward in the width direction (Y-axis direction) is formed in the vicinity of the rear end of each beam member 33 . As shown in FIGS. 1 and 2, upper and lower protrusions 14a and 14b projecting inward in the width direction (Y-axis direction) are formed in the vicinity of the rear ends of the left and right rear side plate portions 13d. there is The vertical displacement of the rear end of the girder member 33, which is the rear end of the lock member 31, is stopped when the projecting piece 38 comes into contact with the upper projection 14a and the lower projection 14b. That is, the upper and lower ends of the range in which the rear end of the beam member 33 can be displaced in the vertical direction are defined by the contact of the projecting pieces 38 with the upper projections 14a and the lower projections 14b. Thereby, the swingable range of the girder member 33 is also defined.

Next, the operation of fitting the connector 1 and the mating connector 101 will be described.

FIG. 6 is a perspective view showing a state in which the connector and the mating connector according to the present embodiment are mated, FIG. 7 is a partial cross-sectional perspective view showing a state in which the connector and the mating connector are mated, and FIG. [Fig. 2] is a partial cross-sectional side view showing a state in which the connector and the mating connector are fitted together according to the present embodiment.

When starting the fitting operation for fitting the connector 1 and the mating connector 101, the operator controls the postures of the connector 1 and the mating connector 101 with fingers or the like so that the positions shown in FIGS. , the front end 11f of the housing 11 of the connector 1 faces the front end of the mating housing 111 of the mating connector 101. As shown in FIG. More specifically, the front end of fitting portion 12 c in housing body 12 of housing 11 is positioned to face the front end of connector receiving cavity 113 in mating housing 111 .

Subsequently, the operator moves the connector 1 relative to the mating connector 101 in the X-axis direction, and inserts the fitting portion 12c of the housing main body 12 of the housing 11 into the connector receiving cavity 113 of the mating housing 111. . Then, the upper surface portion 111 a of the side wall portion 111 b of the mating housing 111 enters between the fitting portion 12 c of the housing body 12 and the front top plate portion 13 a of the cover portion 13 . The front beam member 35 of the lock member 31 moves relatively along the upper surface portion 111a of the mating housing 111 and climbs over the lock projection 135 projecting upward from the upper surface portion 111a.

At this time, the front beam member 35 is first pushed upward by sliding toward the rear of the lock projection 135 along the inclined surface 135a of the lock projection 135 . Then, since the first elastic member 32a and the second elastic member 32b functioning as spring members are elastically deformed, the girder member 33 swings clockwise in FIG. Since the spring member has a substantially L-shaped shape and has a long spring length, it has a wide deformation range and can be deformed flexibly. In addition, since the lower surface of the first elastic member 32a is an inclined surface, the downward movable range of the free end is widened. Therefore, the girder member 33 can swing smoothly, and the front beam member 35 can rise smoothly.

Subsequently, when the operator further moves the connector 1 relative to the mating connector 101 in the X-axis direction, the fitting portion 12c of the housing main body 12 of the housing 11 moves deep inside the connector accommodating cavity 113 of the mating housing 111. , and the mating terminal 151 disposed in the connector accommodating cavity 113 enters the body through hole 21 formed in the housing body 12 and contacts the terminal accommodated in the body through hole 21. to conduct. Further, the sealing member 81 fitted to the fitting portion 12c is sandwiched and compressed between the inner peripheral surface of the side wall portion 111b of the mating housing 111 and the outer peripheral surface of the fitting portion 12c, and the inner peripheral surface of the side wall portion 111b. It seals between the peripheral surface and the outer peripheral surface of the fitting portion 12c. As a result, the connector 1 and the mating connector 101 are mated with each other.

Also, the front beam member 35 of the lock member 31 passes the inclined surface 135a and the top surface 135b of the lock projection 135 and reaches the rear end side of the top surface 135b. As a result, the first elastic member 32a and the second elastic member 32b exhibit springiness and return to the shape before deformation, so that the beam member 33 swings counterclockwise in FIG. do. Then, the front beam member 35 descends along the vertical surface 135 c of the lock projection 135 and engages with the lock projection 135 . Specifically, as shown in FIGS. 7 and 8, the vertical surface 35c of the front beam member 35 and the vertical surface 135c of the lock projection 135 are opposed to each other, and the front beam member 35 and the lock projection 135 are engaged with each other. match. Therefore, the lock member 31 and the lock projection 135 are securely locked, and the engagement between the connector 1 and the mating connector 101 is not unnecessarily released.

In this state, for example, when an external force is applied to release the engagement between the connector 1 and the mating connector 101, such as a force pulling the electric wire 91 rearward (in the negative direction of the X-axis), the front beam member 35 is pulled from the lock projection 135. , the girder member 33 cannot be displaced rearward, but the holding member 32c connected to the upper surface portion 12a of the housing body 12 via the connecting member 32d receives a rearward pulling force. It will happen. Then, the first elastic member 32a and the second elastic member 32b, which are substantially L-shaped spring members whose both ends are connected to the beam member 33 and the holding member 32c, rotate counterclockwise in FIG. As such, it deforms elastically. As a result, the girder member 33 is raised at the portion connected to the upper end of the second elastic member 32b, while the front end is not raised. It becomes difficult to cancel the combination. Therefore, even when an external force is applied to disengage the connector 1 from the mating connector 101, the locking member 31 and the locking projection 135 reliably maintain the lock. are not released.

When it is necessary to release the mating and remove the connector 1 from the mating connector 101, the operator pushes down the rear beam member 37 with a finger or the like, and the girder member 33 rotates clockwise in FIG. , and the front beam member 35 connected to its front end rises. As a result, the engagement between the front beam member 35 and the lock projection 135 is released and the lock is released. 1 can be removed from the mating connector 101 .

Further, the upper and lower ends of the range in which the rear end of the beam member 33 can be displaced in the vertical direction are defined by the protrusions 38 coming into contact with the upper protrusions 14a and the lower protrusions 14b, as described above. As a result, the swinging range of the beam member 33 is limited to a certain extent, and the deformation range of the first elastic member 32a and the second elastic member 32b, which are spring members, is also limited to a certain extent. Therefore, the first elastic member 32a and the second elastic member 32b, which are spring members, are not damaged due to excessive deformation.

Thus, in this embodiment, the connector 1 has a housing 11 made of an insulating material and is mated with a mating connector 101 having a mating housing 111 made of an insulating material. The housing 11 includes a housing body 12, a lock member 31 that locks the lock protrusion 135 of the mating housing 111, and a support member 32 that is connected to the housing body 12 and supports the lock member 31 so as to swing, The lock member 31 connects a pair of left and right girder members 33 extending in the front-rear direction, which is the fitting direction with the mating connector 101 , and front ends of the left and right girder members 33 . The support member 32 includes a member 35 and a rear beam member 37 connecting the rear ends of the left and right beam members 33, and the support member 32 includes a spring member having a substantially L-shaped shape when viewed from the side.

As a result, the click feeling and operability when fitting with the mating connector 101 are good, the lockability is high, and fitting with the mating connector 101 can be reliably maintained. Also, the reliability of the connector 1 is improved, the manufacturing cost is reduced, and the durability is improved.

The spring member has a base end held by a holding member 32c connected to the housing main body 12, and is connected to a first elastic member 32a extending rearward, and a free end of the first elastic member 32a to extend upward. and a pair of left and right second elastic members 32b whose upper ends are connected to the beam members 33. The lower surface of the first elastic member 32a is an inclined surface that rises toward the rear. . Therefore, since the thickness of the first elastic member 32a gradually decreases toward the free end, the force from the left and right beam members 33 is applied to the free end through the second elastic member 32b. The distribution of stress generated inside 32a becomes uniform. In addition, since the distance between the lower surface of the first elastic member 32a and the housing body 12 increases toward the rear, the downward movable range of the free end of the first elastic member 32a increases.

Further, the first elastic member 32a is a plate member extending from directly below one of the beam members 33 to directly below the other beam member 33, and the left and right second elastic members 32b are the first elastic members 32a. It is connected to both left and right ends of the free end. Therefore, since the first elastic member 32a and the second elastic member 32b as spring members have a long spring length from the proximal end of the first elastic member 32a to the upper end of the second elastic member 32b, the deformation range is wide and , can be flexibly deformed. Also, the pair of left and right beam members 33 can swing around the base end of the first elastic member 32a and the upper end of the second elastic member 32b as fulcrums.

Furthermore, the thickness of each beam member 33 is greater than the thickness at the proximal end of the first elastic member 32a. As a result, the first elastic member 32a and the second elastic member 32b function appropriately as spring members when locking or unlocking.

Further, the lock member 31 includes a projecting piece 38 formed in the vicinity of its rear end and projecting outward in the width direction. , and the vertical displacement of the rear end of the locking member 31 is stopped when the projecting piece 38 comes into contact with the upper projection 14a or the lower projection 14b. Therefore, the deformation range of the first elastic member 32a and the second elastic member 32b is also limited to a certain extent, so that the first elastic member 32a and the second elastic member 32b are not damaged by excessive deformation. .

It should be noted that this disclosure describes features of preferred exemplary embodiments. Various other embodiments, modifications and variations within the scope and spirit of the claims appended hereto will naturally occur to those skilled in the art upon reviewing the disclosure herein. be.

The present disclosure can be applied to connectors.
