Description

  The present invention relates to a connector device, and more specifically, includes a connecting member and a connected member to which the connecting member is connected. The connecting member is attached to and detached from the connected member, and the connecting member and the connected member are locked. And the unlocking is performed by pressing and pulling out the connecting member with respect to the connected member, and the connecting member is provided with an unlocking operation unit for unlocking the connecting member with respect to the connected member. The present invention relates to a pull type connector device.

  FIG. 13 schematically shows a configuration example of the push-pull type connector device 1. In the figure, reference numeral 10 denotes a connecting member, and reference numeral 20 denotes a connected member 20 to which the connecting member 10 is connected. FIG. 13 shows a state in which the connecting member 10 and the connected member 20 are connected, and the insertion portion 11 protruding forward from the front end of the connecting member 10 is inserted into the fitting hole 21 of the connecting member 20. Yes. The cross-sectional shapes of the insertion portion 11 and the fitting hole 21 are generally circular or rectangular, but are not limited thereto.

  FIG. 14A shows only the connection member 10 of the connector device 1 shown in FIG. One or a plurality of claws 12 protrude from the outer peripheral surface 11 a of the insertion portion 11. These claws 12 can be projected and retracted with respect to the outer peripheral surface 11a, and are urged in a direction protruding from the outer peripheral surface by a mechanism (not shown). As shown in FIG. 14A, the claw 12 has a wedge shape when viewed from the side, and is shaped so that the protruding dimension increases from the front to the rear of the connection member 10.

On the other hand, the inner surface 21a of the fitting hole 21 of the connected member 20 is connected to the insertion portion 11 of the connecting member 10 in a state where the connecting member 10 and the connected member 20 are connected as shown in FIG. A recess 22 is formed in which the constructed claw 12 is locked.

  The connection member 10 includes a sleeve-like operation member (lock release operation unit) 13 on the outer periphery thereof. The operating member 13 can slide in a certain range along the longitudinal direction of the connecting member 10 (connecting direction of the connector device) on the outer peripheral portion of the connecting member 10. The operation member 13 is related to the movement of the claw 12, and as shown in FIG. 14B, the operation member 13 is placed on the proximal end side of the connection member 10 (that is, in a direction opposite to the insertion portion 11). ) By sliding, the claw 12 biased in the protruding direction as described above can be drawn toward the outer peripheral surface 11a. Such a mechanism is well known and will not be described in detail here.

  The case where the connecting member 10 having the above configuration is connected to the connected member 20 will be described. The connecting member 10 is normally in the state shown in FIG. 14A, and the claw 12 protrudes greatly from the outer peripheral surface 11 a of the insertion portion 11. The connecting member 10 in this state is opposed to the fitting hole 21 of the connected member 20 to be joined, and then the connecting member 10 is pressed toward the connected member 20. By this operation, the insertion portion 11 is inserted into the fitting hole 21. In the middle of this insertion operation, the protruding claw 12 comes into contact with the periphery of the entrance of the fitting hole 21, but the claw 12 is wedge-shaped and can be projected and retracted, so that the claw 12 is inserted as the connecting member 10 is inserted. 12 is gradually pushed into the insertion portion 11, and thus the insertion operation is not hindered by the claw 12.

  In this way, when connecting the connecting member 10 to the connected member 20, the connecting member 10 may be inserted by holding the operating member 13. As described above, the operation member 13 forcibly pulls the claw 12 when it is slid to the proximal end side of the connection member 10, but the claw 12 due to external force when positioned on the distal end side. It is because it does not prevent the pull-in.

  At a position where the insertion portion 11 is inserted into the fitting hole 21 with a predetermined size and the connecting member 10 and the connected member 20 are correctly connected, the claw 12 reaches the recess 22 formed in the fitting hole 21. Therefore, it protrudes outward by the biasing force described above. The projecting claw 12 enters and locks into the recess 22 to lock the connecting member 10 with respect to the connected member 20.

  Thus, when removing the connecting member 10 from the state where the connecting member 10 and the connected member 20 are connected, the connecting member 10 may be pulled out of the connected member 20 by holding the operation member 13. In the initial stage of this operation, since the claw 12 is locked in the recess 22, only the operation member 13 slides on the connection member 10 to the proximal end side. Thereby, the nail | claw 12 is drawn toward the inside of the insertion part 11, and the latching | locking of the nail | claw 12 and the recess 22 is released. If the connection member 10 is further pulled in the pulling direction by holding the operation member 13 from here, the connection member 10 is detached from the connected member 20.

  As described above, the push-pull type connector device as described above is well known, but as another example of the push-pull type connector device, there is Patent Document 1, for example.

Japanese Utility Model Publication No. 45-11753

  As described above, the push-pull type connector device is connected by simply pushing the connecting member 10 into the connected member 20, and the connection is securely locked. On the other hand, when releasing the connection, the operation member of the connecting member 10 is used. The connector device is a very convenient connector device in that the lock can be released simply by pulling out the connecting member 10 with 13 and the connecting member 10 can be detached from the connected member 20.

  However, on the other hand, since the connecting member 10 is detached from the connected member 20 only by pulling the connecting member 10 in the pulling direction by holding the operation member 13, there is a concern that the connection of the connector device is unintentionally disconnected. . A connector device simply realizes a structural connection, for example whether it is an electrical connector device to transmit electrical signals, an optical connector device to transmit optical signals, or a fluid connector device to connect fluid flow Whether it is a mechanical connector device or other connector device, it is responsible for the transmission of some physical material, signal, energy, or force from one transmission path to the other. Thus, the unintentional disconnection of the connector device can sometimes have serious consequences.

  The present invention has been made in view of the above circumstances, and can be easily and reliably locked, and can be surely prevented from unintentional unlocking, that is, unintentional disconnection of the connector device. An object of the present invention is to provide a connector device.

  The present invention has been made in view of the above circumstances, and includes a connecting member and a connected member to which the connecting member is connected. The connecting member is attached to and detached from the connected member, and the connecting member and the connected member are provided. The locking and unlocking of the connecting member is performed by pressing and pulling out the connecting member with respect to the connected member, and the connecting member includes a lock releasing operation unit for unlocking the connecting member with respect to the connected member. In the push-pull type connector device device, the unlocking operation unit is movable in a direction in which the pressing / pulling operation is performed, and the unlocking operation is performed in a state where the connecting member and the connected member are connected. It is provided with a movement preventing means for preventing the movement of the part in the unlocking direction.

  According to the present invention, in the push-pull type connector device that can prevent the unlocking operation portion from moving in the unlocking direction by the movement preventing means, and that is easy to insert and remove, the connecting member is not intended. Can be prevented from coming off the connected member.

The said movement prevention means can be comprised separately from a connection member and a to-be-connected member, and can be comprised as a movement prevention member made detachable with respect to a connection member and / or a to-be-connected member.
With this configuration, the apparatus according to the present invention can be configured very simply.

The unlocking operation portion is formed in a sleeve shape having an outer peripheral surface as an operation surface, and the movement preventing member is engaged with an end surface in the unlocking direction of the unlocking operation portion to move the unlocking operation portion. It can be set as the structure provided with the movement prevention engaging part to block.
In this configuration, various forms can be adopted as the movement preventing member provided with the movement preventing engaging portion.

The movement preventing member is preferably made of an elastic material and configured in a substantially C shape when viewed in the axial direction of the connector device.
Thereby, the movement preventing member is easily attached to and detached from the connecting member and / or the connected member.
Here, “substantially C-shaped” means that it is a thin plate-like member or a cylindrical member having a certain length in the axial direction, when viewed from the axial direction of the member. It means that the cross section is not connected to the whole ring, and a part thereof is notched. Therefore, the cross-sectional shape of the substantial part (the part that is not cut) does not necessarily have an arc shape, and the substantial part may be, for example, a part of a rectangle or a part of another polygon.

The connecting member has a flange portion protruding in a radial direction at a position spaced from an end surface of the movement preventing member in the unlocking direction, and the movement preventing engaging portion is arranged in the unlocking direction of the movement preventing member. It can be set as the structure engaged with the cyclic | annular space | gap part formed between the end surface and this flange part.
In this case, it is possible to make the movement preventing engagement portion extremely simple by using the flange provided in the connection member.

It is convenient if the movement preventing member is configured to cover at least a part of the sleeve-like unlocking operation portion over its entire length.
In this configuration, since most of the lock release operation part is hidden by the movement preventing member, there is an advantage that access to the movement preventing member itself can be prevented.

The connected member has a flange portion protruding in a radial direction of the connected member, and the movement preventing member includes a flange formed on the connected member and an end face of the unlocking operation portion in the unlocking direction. You may make it provide so that it may engage.
It is also possible to adopt a configuration in which the flange portion is formed on the connected member in this way and one end of the movement preventing member is locked to the flange.

The movement preventing member is conveniently provided with a knob portion extending in a direction orthogonal to the connector device connection direction.
In this case, the movement preventing member can be easily removed from the connecting member and / or the connected member.

  The connector device according to the present invention can also be applied to medical equipment. The medical device may be a heart pump (blood pump), for example, and can greatly contribute to prevention of a serious accident such as unintentional connector disconnection.

  According to the present invention, in the push-pull type connector device that can prevent the unlocking operation portion from moving in the unlocking direction by the movement preventing means, and that is easy to insert and remove, the connecting member is not intended. Can be prevented from coming off the connected member.

(A) And (b) is a figure which shows the connection member of the conventional connector apparatus.

  FIG. 1 shows a connector device 1A according to a first embodiment of the present invention. The connector device 1A is a push-pull type connector device, and is roughly composed of a connecting member 10A, a connected member 20A to which the connecting member 10A is connected, and a movement preventing member (movement preventing means) 30A described later. Composed. The connecting member 10 </ b> A is configured at one end of the line 40. The connected member 20A is also configured at one end of a line not shown. The line 40 transmits any physical substance, signal, energy, etc., such as a fluid conduit, an electric signal cable, and an optical cable, and is not particularly limited. For example, the line 40 does not flow a substance or a signal inside, but may be a simple solid bar or wire. In that case, the connector device 1A functions as a structural connection of such solid bars or wires.

  Although omitted in the drawing, it goes without saying that the internal structures of the connecting member 10A and the connected member 20A are configured according to those transmitted by the line 40. That is, for example, when the line 40 is a conduit that allows fluid to pass through, the internal structure of both the members 10A and 20A is configured to reliably transmit the fluid from one to the other without leakage. For example, when the line 40 is an electric signal cable, the internal structure of both members 10A and 20A includes an electric terminal.

  The configuration of the connecting member 10A and the connected member 20A is basically the same as that of the connecting member 10 and the connected member 20 described above with reference to FIGS. The insertion portion 11 protruding forward from the front end of the connecting member 10A is inserted into the fitting hole 21 of the connecting member 20A. The cross-sectional shapes of the insertion portion 11 and the fitting hole 21 are generally circular or rectangular, but are not limited thereto. Furthermore, the cross-sectional shapes of the connecting member 10A and the connected member 20A are not limited.

  A flange portion 14 protruding in the radial direction is formed on the proximal end side of the operation member 13 in the connecting member 10A. As a result, an annular gap 15 is formed between the proximal end surface 13 b of the operation member 13 and the front surface 14 a of the flange 14.

  A movement preventing member 30A is attached to the outer periphery of the connecting member 10A. As shown in FIGS. 2 and 3, the movement preventing member 30 </ b> A includes a main body portion 31 provided on the connecting member 10 </ b> A so as to cover substantially the entire operation member (unlock operation portion) 13, and the main body portion 31. And a protruding knob 38. The movement preventing member 30A is entirely composed of a resin rich in elasticity. More specifically, as the resin in that case, an ABS resin or a nylon resin having an appropriate viscosity is preferable.

  As shown in FIGS. 2 and 3, the main body 31 as a whole has a C-shaped cross section in which a part of a wall portion constituting the cylindrical body is cut out by a predetermined width along the axial direction of the cylindrical body. Yes. Combined with this shape and the characteristics of the material constituting the main body 31, the main body 31 can be elastically deformed so that the C-shaped opening 32 is opened. Therefore, the movement preventing member 30A is detachable from the connecting member 10 as shown in FIGS. The length in the axial direction of the main body 31 is substantially the same as the length in the axial direction of the operating member 13 of the connecting member 10, and more specifically, slightly longer than the operating member 13. It is preferable that the C-shaped main body 31 is set so that the inner surface thereof is in close contact with the outer surface of the sleeve-like operation member 13 when the movement preventing member 30A is attached to the connecting member 10A. .

  As shown in FIG. 1, flanges 33 and 34 projecting inward in the radial direction of the main body portion are formed at both ends of the main body portion 31. The distance between the inner surface 33a of the flange portion 33 on the distal end side and the inner surface 34a of the flange portion (moving engagement engaging portion) 34 on the proximal end side is substantially equal to the axial length of the operating member 13, and therefore this movement In a state where the prevention member 30A is attached to the connecting member 10A, the distal end side end surface 13a of the operation member 13 is in contact with the inner surface 33a, and the proximal end side end surface 13b of the operation member 13 is in contact with the inner surface 34a. Become.

  The width of the flange 34 on the base end side (dimension in the axial direction of the main body) is equal to the width of the annular gap 15, and specifically, it is preferably slightly smaller than the width of the annular gap 15. Although the width of the flange portion 33 on the distal end side is not particularly defined, it is preferable that the width of the flange portion 34 is approximately the same as that of the flange portion 34 from the viewpoint of symmetry of the rigidity of the entire main body portion 31. The inwardly protruding dimensions of the flange parts 33 and 34 are such that the protruding ends of the flange parts 33 and 34 do not contact the constituent parts of the connecting member 10 so that the main body part 31 does not float from the operation member 13. Should be set.

  The opening width of the opening portion 32 of the main body portion 31 should not exceed the diameter of the main body portion 31 having a C shape at the maximum. If this is the case, the main body 31 will easily come off the connecting member 10. From this point of view, it is preferable that the width of the opening 32 be as narrow as possible. On the other hand, from the viewpoint of detachability and visibility of the operation member 13, it is preferable that the opening has a certain size. . Further, the detachability of the movement preventing member 30A acts as rigidity (deformability) of the main body 31, that is, the elasticity of the resin constituting the main body, the thickness of the main body, and in this case, resists deformation. Therefore, the opening width of the opening 32 is appropriately set in consideration of these conditions. In general, if the opening width of the opening 32 is expressed by the central angle in the cross section of the main body 31, it will be an angle of about 90 ° or narrower as shown in the illustrated example.

  As can be seen from FIGS. 2 and 3, the knob portion 38 is formed so as to protrude radially outward of the main body portion from the back side of the main body portion 31. The knob portion 38 is pinched with a finger when the operator of the connector device handles the movement preventing member 30A, particularly when removing the movement preventing member 30A from the connecting member 10.

  Although the knob portion 38 according to the illustrated example is formed integrally with the main body portion 31, the knob portion 38 may be formed separately and joined to the main body portion 31.

  The operation of the connector device 1A according to the first embodiment of the present invention configured as described above will be described below.

  In the connector device 1A, the movement preventing member 30A is not provided in a state before being connected. Therefore, the operation at the time of connection of the connector device 1A and the action of each member are the same as those shown in FIGS. 13 and 14 and described in paragraphs [0006] to [0008].

  When the connecting member 10A and the connected member 20A are connected to each other and locked, the movement preventing member 30A is attached to the connecting member 10A as shown in FIG. At this time, as shown in FIG. 1, the movement preventing member 30 </ b> A can be removed so that the main body 31 covers the operation member 13 of the connecting member 10 </ b> A. In this state, the base end side flange portion 34 of the main body portion 31 is fitted into the annular gap portion 15.

  In order to attach the movement preventing member 30A in this way, after the opening 32 of the main body 31 of the movement preventing member 30A is brought close to the outer surface of the operation member 13 to be attached, the entire movement preventing member 30A is moved to the operation member 13. Just push it in lightly. Although the opening width of the opening portion 32 is smaller than the diameter of the operation member 13, the main body portion 31 can be elastically deformed, so that the main body portion 31 is deformed and the opening portion 32 is opened by this pushing operation, and the main body portion 31 is the operation member. 13 is mounted on.

  Thus, the state in which the movement preventing member 30A is attached to the operation member 13 is the normal use state of the connector device 1A. In this state, most of the operation member 13 is covered with the movement preventing member 30, and the operation member 13 is substantially hidden by the main body 31 of the movement preventing member 30A. Therefore, the operation member 13 is not intended. Operation is prevented. A part of the operation member 13 is seen from the opening 32 of the movement preventing member 30A. Therefore, it is not impossible to access the operation member 13 at this part. However, even if a force in the unlocking direction is applied to the operation member 13, as can be seen from FIG. 1, the proximal end surface 13 b of the operation member 13 is in contact with the inner surface 34 a of the flange 34 on the proximal end side. And since the collar part 34 is engaging with the said annular clearance part 15, the operation member 13 does not move to a lock release direction.

  On the other hand, when the connector device 1A is intentionally removed, first, the movement preventing member 30A is removed from the connecting member 10. For this purpose, the knob portion 38 of the movement preventing member 30A may be picked and pulled outward in the radial direction of the connecting member 10A. The movement preventing member 30 </ b> A is elastically deformed so as to increase in diameter from the opening 32 of the main body 31 and is detached from the connection member 10 </ b> A. Thereafter, the connecting member 10 </ b> A may be pulled out of the non-connecting member 20 </ b> A while pulling down the operation member 13 in the unlocking direction, as in the conventional general push-pull type connector device 1 described above.

  As described above, according to the above-described push-pull type connector device 1A, the connection member 10A and the connected member 20A can be easily connected and locked, while the movement preventing member 30A is provided with the operation member. 13 prevents the operation member 13 from moving unintentionally, the connector device is unlocked, and the accident that the connecting member 10A comes out of the connected member 20A is reliably prevented. it can.

  Furthermore, in the thing of the said embodiment, since the movement prevention member 30A becomes a form which covers most parts of the operation member 13, the access itself to the operation member 13 can also be restrict | limited largely, In addition, presence of the movement prevention member 30A itself Can be appealed to the operator's vision. Furthermore, if the color of the movement preventing member 30A is different from that of the connecting member 10A, the visual effect increases.

  When the movement preventing member 30A, which is a separate member from the connecting member 10A and the connected member 20A, is hung from the connecting member 10A or the connected member 20A or the line 40 using a string or the like, when removed from the connecting member 10A Can be prevented from being lost.

  If the entire connecting member 10A including the operation member 13 is circular in cross section as in the illustrated example, the inner surface of the main body 31 of the movement preventing member 30A is also cylindrical, so that the operation member 13 is It is also possible to configure so that it can rotate on the connecting member 10A. In the case of such a configuration, the movement preventing member 30A can be rotated by holding the knob portion 38, thereby bringing the knob portion 38 to a desired position.

  FIG. 4 shows a connector device 1B according to a second embodiment of the present invention. In the following embodiments including this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The configuration of the connecting member 10B is the same as that of the connecting member 10A shown in the first embodiment. On the other hand, the connected member 20B is not configured at the end of the cable like the connecting member 10B, but is configured on the front surface 91a of the casing 91 of the specific device 90. Other configurations are the same as those of the connector device 1A according to the first embodiment. Therefore, the same effect as the connector device 1A can be obtained in the connector device 1B according to this embodiment.

  5 and 6 show a connector device 1C according to a third embodiment of the present invention. In this embodiment, as can be seen from FIG. 6, a flange portion 41 protruding in the radial direction is formed at the distal end portion of the connected member 20 </ b> C. On the other hand, the connection member 10 </ b> C in the present embodiment does not include an element corresponding to the flange portion 14 formed in the connection members 10 </ b> A and 10 </ b> B in the first embodiment and the second embodiment.

  In the present embodiment, the movement preventing member 30C is provided so as to extend from the operation member 13 of the connecting member 10C to the flange portion 41 as shown in FIG. For this reason, in the state of FIG. 5, the point which the one collar part 34 of the movement prevention member 30C is latched by the base end side end surface 13b of the operation member 13 is the same as the said movement prevention members 30A and 30B in previous embodiment. However, the other flange 33 of the movement preventing member 30 </ b> C is engaged with the flange 41, not the operation member 13. The other configuration of the movement preventing member 30C is the same as that of the movement preventing members 30A and 30B.

  In the connector device 1C according to the third embodiment, like the above embodiment, the movement preventing member 30C can surely prevent the operation member 13 from being moved in the unlocking direction unintentionally. In the thing of the 1st and 2nd embodiment, the movement to the unlocking direction of the operation member 13 was blocked | prevented because the collar part 34 of the base end part of a movement prevention member was interposed in the annular gap | interval part 15. FIG. Instead, in the third embodiment, the flange portion 33 of the movement preventing member 30C is locked to the flange portion 41 of the connected member 20C, thereby preventing the operation member 13 from moving in the unlocking direction. .

  7 and 8 show a connector device 1D according to a fourth embodiment of the present invention. The present embodiment has a simple configuration as compared with those of the first to third embodiments. Both figures show only the connecting member 10D and the movement preventing member 30D among the components of the connector device 1D. The configuration of the connection member 10D is the same as the connection members 10A and 10B of the connector device according to the first and second embodiments.

  In the fourth embodiment, the movement preventing member 30 </ b> D includes a C-shaped main body portion 31 and a knob portion 38 extending from the book interior 31. However, the overall size of the main body 31 in the connector device axial direction is extremely smaller than that of the above embodiment, and the width corresponding to the annular gap 15 (in other words, the main body in the first embodiment). Only the same width as the base end side flange portion 34 of the portion 31). Accordingly, in this case, the main body portion 31 has a plate shape as a whole, and the knob portion 38 extending from the main body portion 31 is also formed in the same plate surface as the main body portion 31.

  The basic usage of the connector device 1D according to the fourth embodiment is the same as that of the first to third examples already described. However, the main body portion 31 of the movement preventing member 30D of the connector device 1D according to the present embodiment is fitted into the annular gap portion 15 as shown in FIG. 7, and the operation member 13 is moved as in the first to third embodiments. Do not cover. That is, in the present embodiment, the entire main body 31 of the movement preventing member 30D serves as a movement preventing engagement part.

  In the connector device 1D according to the present embodiment, since the movement preventing member 30D does not surround the operation member 13 at all, there is no effect of reducing the opportunity of access to the operation member 13 itself. Even if a force in the unlocking direction is applied unintentionally, the movement preventing member 30D reliably prevents the operation member 13 from moving. Therefore, unintentional detachment of the connector device can be surely prevented by this connector device 1D.

  9 and 10 show a fifth embodiment of the present invention. The fifth embodiment is an example in which the present invention is applied to an L-shaped connector device in which a connecting member 10E or a line 40 extending from the connecting member 10E is bent in an L shape.

  In this case, the main body 31 of the movement preventing member 30E is configured in an L-shaped tube as a whole so as to follow the shape of the L-shaped connector device. An opening 32 is formed in the main body 31 along the length direction thereof. The opening 32 is formed so as to run inside the L-shaped bent portion. On the inner surface of one end of the main body 31, more precisely, the end close to the operation member 13, a flange portion (movement preventing engagement portion) 35 protruding inward in the radial direction is formed. The flange 35 is dimensioned so that it can be fitted into the annular groove 15 of the connecting member 10E. On the inner surface of the other end portion of the main body portion 31, a flange portion 36 that protrudes inward in the radial direction is also formed. When the movement preventing member 30E is attached to the connection member 10E and the line 40, the flange 36 narrows the gap with the line 40 and suppresses rattling, and reduces the overall rigidity of the movement preventing member 30E. Secure.

  Further, the movement preventing member 30E in this embodiment does not include a knob portion extending outward. Instead, slight concave portions 37 are formed on the outer surface of the main body portion 31 at two opposed positions where the main body portion 31 can be gripped with a thumb and another finger, for example.

  In order to attach the movement preventing member 30E according to this embodiment to the L-shaped connector device, as shown in FIG. 10, the movement preventing member 30E is placed on an extension line of the line 40 with the opening 32 facing the connecting member 10E. The movement preventing member 30E is slid on the line 40 in the direction of the arrow in the figure (in this case, the downward arrow direction) from that position so as to cover the line 40. The final state is a state in which the flange 35 enters the annular gap 15.

  In the connector device 1E according to the present embodiment, even when an unintended unlocking force is applied to the operation member 13, the movement of the operation member 13 is provided so that the collar portion 35 is locked to the annular gap portion 15. Therefore, the operation member 13 does not move. Therefore, in this embodiment, the present invention can be easily applied to an L-shaped connector device, and unintentional disconnection of the connector device can be reliably prevented.

  In the connector device 1E according to the fifth embodiment, since a part of the movement preventing member 30E is provided for the line 40, the line 40 is protected by the movement preventing member 30E at that portion.

  Next, FIGS. 11A to 11C show a connector device 1F according to a sixth embodiment of the present invention. In the present embodiment, the connecting direction of the connecting member 10F and the extending direction of the line 40 do not coincide with each other, and the so-called L-shape that forms a substantially right angle (the illustrated example is slightly offset from the right angle). It is the same as the connector device 1E according to the fifth embodiment in that it is a connector device. However, in the connector device 1F of the present embodiment, the connecting member 10F and the line 40 themselves constituting the connector device are each linear, while the line 40 is located on the side of the connecting member 10F and the connecting direction of the connecting member 10F. Is connected at an angle.

  The line 40 is connected to the connection member 10F in the region of the operation member 13 of the connection member 10F. For this reason, as seen in the figure, the operation member 13 has a notch 13c so that the operation member 13 and the line 40 do not interfere with each other. The notch 13c has an elongated shape so that the operation member 13 can slide between the lock position and the lock release position.

  The rear end (the end opposite to the connection end) of the connection member 10F is terminated with a flange portion 14, and an annular gap portion 15 is formed between the front surface 14a of the flange and the proximal end surface 13a of the operation member 13. Is formed.

  As shown in FIG. 11A, the movement preventing member 30F of the connector device in the present embodiment is provided by being supported by a line 40 as a whole. The movement preventing member 30F extends the knob portion 38 of the movement preventing member 30D of the connector device 1D according to the fourth embodiment shown in FIGS. It has a shape in which a mounting portion 39 having an open cylindrical shape in which a part of the surface is cut off in the longitudinal direction is provided. As can be seen from FIG. 11A, the movement preventing member 30 </ b> F is used in a state where the attachment portion 39 is attached to the line 40.

  FIG. 11A shows a state in which the movement preventing member 30 </ b> F is functioning, and a C-shaped main body portion 31 extending from the attachment portion 39 is engaged in the annular gap portion 15. In this case, the C-shaped opening 32 of the C-shaped main body 31 is located on the side opposite to the side on which the mounting portion 39 is mounted.

  An inner diameter of the mounting portion 39 having an opening side surface extending in the longitudinal direction and having a cylindrical shape as a whole is set smaller than an outer diameter of the line 40 in a free state. Further, since the movement preventing member 30F has elasticity, the movement preventing member 30F can remain on the line 40 by the gripping force obtained by the configuration and properties of the mounting portion 39.

  In the state of FIG. 11, the movement of the operation member 13 in the unlocking direction is prevented by the main body portion 31 engaged with the annular gap portion 15. Therefore, in the present embodiment, the main body portion 31 constitutes a movement preventing engagement portion.

  When the connector device 1F is intentionally removed, first, the movement preventing member 30F is moved in the direction indicated by the downward arrow as shown by a chain line in FIG. In that case, the mounting portion 39 is slid on the line 40. As a result, the C-shaped main body 31 is detached from the annular gap 15.

  Thereafter, as shown by a solid line in FIG. 11B, the attachment portion 39 is pulled in a direction orthogonal to the line 40, and the movement preventing member 30 </ b> F is removed from the line 40. When the attachment part 30 is detached from the line 40, the line 40 passes through the opening 39 a of the attachment part 39.

  After that, as shown in FIG. 11 (c), the operation member 13 can be moved in the unlocking direction, and then the operation member 13 is pulled out in the anti-connection direction (the same as the unlocking direction) The connecting member 10F can be pulled out from a connected member (not shown).

  In the above description, the state shown in FIG. 11B, that is, after the main body portion 31 is detached from the annular gap portion 15, the movement preventing member 30F is removed from the line 40, and then the operation member 13 is operated. However, the operation member 13 may be operated when the state indicated by the chain line in FIG. In that case, the movement preventing member 30F remains on the line 40, which is advantageous in view of the loss of the movement preventing member 30F.

  FIG. 12 shows an example in which the connector device according to the present invention is applied to a blood pump (heart pump). In the figure, reference numeral 100 denotes a blood pump. The blood pump 100 is used for maintaining blood circulation, for example, during open heart surgery. To explain only the outline of the blood pump 100, a casing 101, a drive unit 102, and a rotational force generated by the drive unit 102 are used. And an impeller 104 attached to the output shaft 103. A suction port 105 is formed in the upper part of the casing, and a discharge port 106 is formed in the upper side. The impeller 104 is rotated by the driving force of the drive unit 102, and the blood flowing in from the suction port 105 is sent out to the discharge port 106 through the impeller 104.

  The connector device according to the present invention is applied to the suction port 105 and the discharge port 106 of the blood pump (heart pump) 100 configured as described above. In other words, the suction port 105 and the discharge port 106 are connected to the connection member 10G and the connection member 10H having the same configuration as the connection member 10A configuring the connector device 1A according to the first embodiment. The connection member 10G is configured at the end of the blood return line 107, and the connection member 10H is configured at the start of the blood feed line 108.

  A recess 22 is formed on the inner surface of the suction port 105 in the vicinity of the opening, and the claw 12 of the insertion portion 11 of the connection member 10G is locked. A recess 22 is formed in which the claw 12 of the insertion portion 11 of the connecting member 10H is locked. That is, in this case, the vicinity of the suction port 105 and the vicinity of the suction port 106 constitute the connected members 20G and 20H of the connector device, respectively.

  The operations of these connector devices 1G and 1H are basically the same as those described in the first embodiment or the second embodiment. If one connector apparatus 1H comprised in the said discharge port 106 is demonstrated, the state of illustration is a connection state of the connector apparatus 1H so that it may be clear. The insertion portion 11 of the connection member 10H is inserted into the fitting hole 21 of the connected member 20H, and the claw 12 protruding from the outer surface 11a of the insertion portion 11 is engaged with the recess 22 on the inner surface of the fitting hole. Thereby, the connecting member 10H is connected to the connected member 20H in a locked state. The operation member 13 of the connecting member 10H is provided with a movement preventing member 30H. The flange portion 34 on the flange portion 14 side of the movement preventing member 30H is fitted in the annular gap portion 15. Therefore, even if the operation member 13 is unintentionally given a force to move the operation member 13 in the unlocking direction, the operation member 13 is prevented from moving.

  To remove the connecting member 10H from the connected member 20H (ie, the discharge port 106), the movement preventing member 30H is removed from the connecting member 10H, and then the operating member 13 is slid in the direction of the flange portion 14. As a result, the claw 12 moves inward, and the engagement between the claw 14 and the recess 22 is released (unlocked). If the connecting member 10H is further pulled in the pulling direction while holding the operation member 13, the connecting member 10H is detached from the blood pump 100.

  Therefore, when the connection member 10H is intended to be removed with a clear intention, it is unexpected that the connection member 10H is disconnected from the connected member 20H (discharge port 106), that is, the blood feed line 108 is disconnected from the blood pump 100. Absent. The same applies to the connector device 10G related to the blood return line 107. In such devices as blood pumps, unintentional disconnection of the line leads to a serious accident and is not allowed. According to the present invention, such an accident can be reliably prevented by extremely simple means.
