Description

  The present invention relates to a fitting locking structure that prevents fitting locking from being removed and facilitates fitting insertion and removal when connecting and connecting connectors such as opening / closing or partitioning of a lid of a cable duct. About.

  A conventional cable duct having a configuration in which a cable is stored in a plate-shaped cable duct and then closed in a predetermined shape is a wiring duct. The wiring duct is a cord-wire such as a covered electric wire in the plate-shaped duct body 1. Is inserted and wired, and the lid is closed after the insertion and wiring, and the wiring duct is closed by engaging with the substantially hook-shaped engaging portions at the tips of the third male protrusion 6e and the fourth female protrusion 6f. The plate-shaped duct body 1 has been proposed to be used as a wiring duct. (For example, see Patent Document 1)

  Further, there is a connection locking structure for closing a bendable cable duct filed by the applicant of the present application. When the cable duct is formed as a cable duct having a predetermined shape by closing the plate-shaped cable duct, It is an object that can be easily stopped, and can be opened and closed by a concave locking body and a projecting locking body, and the concave locking body abuts and locks against one of the tip portions. And forming a hook-like tip locking portion on the other side, forming a guide holding portion on the back side thereof, and forming the tip length of the tip locking portion disposed inside the cable duct slightly shorter, Also, the embodiment is disclosed and proposed in which a base end locking part is formed on both the upper and lower sides of the base end side of the protruding locking body at the other end and a guide part is formed on the front end side. (For example, see Patent Document 2)

  Further, there is a plate-like connector such as a panel filed by the applicant of the present application, and the connector has a concave locking body and a projecting engagement substantially similar to the connection locking structure for closing the bendable cable duct. Fitting and coupling by a coupling tool which is a coupling locking body having a structure in which a stationary body is formed, and a generally known mushroom-shaped projection and a concave portion having a narrowed portion on the front side corresponding to the projection. Disclosed and proposed in examples such as temporary partitioning and partitioning. (For example, see Patent Document 3)

  Furthermore, the generally known fitting locking structure has a mushroom-shaped protrusion and a recess having a narrowed portion on the front side corresponding to the protrusion, and the mushroom-shaped protrusion is fitted in the recess. In many cable ducts that are locked and fitted at the constriction at the front end of the recess, and in the conventional cable duct, a cover is fitted and closed in the cable duct housing. In addition, many hooks and hooks are used and well known.

  JP 2001-37039 A   Japanese Patent Application No. 2007-065796   Japanese Patent Application No. 2007-232059

  In the connection structure of the conventional wiring duct described in Patent Document 1 described above, the wiring duct is closed by locking with the hook-shaped locking portions at the tips of the third male protrusion 6e and the fourth female protrusion 6f. In the locking structure, the substantially hook-shaped locking surfaces at the tips of the third male protrusion 6e and the fourth female protrusion 6f are abutted and locked with each other by flat surfaces. Depending on the strain direction, the lock can be easily removed.For example, if a relatively thick cable with many bends is stored, the cable may come into contact with the upper lid, and the lid will come off due to the contact. However, it was weak against such a force in the direction of removing from the inside, and a response was required.

  In addition, a cable having such a locking structure is effective when a cable with a relatively small amount of storage and a lid of a wiring duct is opened and closed relatively frequently. There was a need for a lid that could not be easily opened due to some distortion.On the other hand, it was difficult to close the lid when the lid of the wiring duct was closed. There is a demand for a locking structure having a contradictory function, which is bad and therefore easy to close and difficult to remove the lid.

  Further, the bendable cable duct of Patent Document 2 has an abutment locking portion on one side of the concave locking body and a hook-shaped tip locking portion on the other side, and a guide holding portion on the back side thereof. Because it is formed on the distal end side, if the cable duct itself is deformed excessively, the deformation on the distal end side increases due to the length of the guide holding part on the back side (the length from the base end to the tip of the guide holding part). The deformation of the abutment locking portion and the distal end locking portion at the tip may be increased and come off, and the guide portion on the tip side of the projecting locking body at the other end opens the guide holding portion by the above deformation. In addition, there is a need for an improvement that acts in the direction as well, and that the possibility of disengagement increases as the deformation of the abutment engaging portion and the distal end engaging portion at the tip increases, and that it does not easily disengage even when greatly deformed.

Further, the connecting member of the plate-like body such as the panel of Patent Document 3 is substantially the same as the connection locking structure of the bendable cable duct of Patent Document 2, and there is a problem that the fitting locking is easily released when greatly deformed. For example, when an object or a person hits the cable duct and deforms, or when the partition is assembled , the cable duct may be greatly deformed and come off.

  In addition, in the generally known fitting locking structure described above, a fitting locking structure having a mushroom-like protruding portion and a concave portion corresponding to the protruding portion that are commonly used can be bent. Even if it is used for a cable duct, it does not easily come off, but conversely, it is difficult to fit, making the cable storage work and closing the cable duct complicated and easy to fit. If the concave portion was formed loosely, it could not be used because it easily detached due to the amount of cable storage and distortion of the cable duct.

  And, in particular, the operation of wiring and closing the lid by fitting the lid to the cable duct which is long and continuous in the longitudinal direction and having a fitting lock structure as described above is difficult to fit. Therefore, storing the cable and closing the lid is cumbersome and time consuming, and the cost is high.In addition, when the cable is stored in a large amount, the cable becomes obstructive and the lid is difficult to close. Due to the inefficiency, there are many commercially available products that can be fitted relatively loosely. Therefore, there were cases where the lid was detached and dropped off, and there was a demand for a contradictory effect that the lid was easy to close and difficult to remove. .

As a means for effectively achieving the above-mentioned problems, the present invention has a concave locking body having a substantially U-shaped end surface on one side of the fitting locking body and a shape in which the tip end bulges on the other side. A projecting locking body is formed, and the concave locking body includes a fitting locking portion, a retaining locking portion, a fitting locking guiding portion, and a guide opening at the tip of the opening. Each of the locking engagement portions is formed so as to protrude from each other at a predetermined position in a substantially U shape and narrowed between the engagement locking portions. And the locking engagement portion are formed such that the deformation is smaller than that of the guide opening portion and the engagement locking guiding portion, and the protruding locking body has a protruding insertion portion formed in a substantially tip tapered shape. In addition, the base side of the projecting insertion portion is formed with a stepped retaining locking portion so as to have the bulging shape, and the retaining locking portion of the fitting locking portion prevents the projecting locking body from being removed. Locking part Since the formed such that Hamagogakaritome in sandwiched form,
When closing a plate-shaped cable duct to form a cable duct of a predetermined shape, opening / closing and unfolding the cable duct lid, or connecting connection such as a partition or partition, etc. When it is necessary to remove it, it will work easily.

The present invention is configured so that an effective effect can be obtained by the above-described means, and particularly on one side of a fitting locking body for opening / closing or fitting connection such as opening / closing or partitioning and partitioning of a cable duct lid. a recessed retaining body shaped end surface substantially U tip portion on the other side at the set of the Hamagogakari stop member projecting stoppers were respectively formed in a shape bulging, the concave engaging The body is formed with a fitting locking portion, a retaining locking portion, a fitting locking guiding portion, and a guide opening at the tip of the opening from the innermost end of the substantially U-shape, The locking portion is formed so as to protrude at a predetermined position in a substantially U-shape so as to face each other, and the space therebetween is narrowed, and the fitting locking portion and the retaining locking portion are connected to the guide port portion. and formed so as to deform than the fitting engagement guiding portion is reduced, while the protruding engagement Tometai is above bulged shape ahead Part is so easy insertion into the induction port portion, the base portion side of the projecting-like insert portion so as to correspond engagement with the retaining engagement portion to form a protrusion insertion portion in a substantially distal tapered, stepped to form a retaining engagement portion of the shaped urging the said bulged shape, retaining engagement portion of the fitting engagement portion is fitted a retaining engagement portion of the projecting holding member to the holding shape Since it is formed so as to lock together
In use, when engaging and locking the concave locking body and the projecting locking body, such as when the cable duct is housed in a cable duct and closed, or when connecting or connecting partitions or partitions, etc., the concave locking body Since the guide opening part and the fitting engagement guiding part are soft, thin, or wide, the protruding engagement body can be easily inserted and temporarily held from the induction opening part to the fitting engagement guiding part.

And, when the fitting locking part is completely fitted and held from the temporary holding state in which the protruding locking body is restricted in the above-described fitting locking guiding part, When the projecting latch is inserted further from the regulated temporary holding state, it can be easily inserted and fitted into the mating latching portion without causing insertion displacement, and the projecting latch can be retained. When inserting and locking from the locking part to the fitting locking part at the back, the retaining locking part fits and locks the retaining locking part of the projecting locking body in a pinched manner, Even if there is a deformation in the cable duct or partition and partition etc. on the main body side of the fitting locking body, it will not easily come off, so it is easy and easy to close even in an incomplete state, improving work efficiency However, the cost is reduced by reducing the work cost.

Further, when the projecting latching body is removed from the concave latching body, the guiding port portion and the fitting locking guiding portion are soft, thin, or wide, so that the guiding port portion together with the fitting locking guiding portion larger turn over so is largely deformed can be opened, become the extreme also open to transform a result retaining engagement portion as turning, easily disconnected projecting locking member from Hamagogakari stop portion, projecting the engaging member can be the pull a little force, but deformation at typical usage, easily disengaged so that no opening as turning as described above, easy to insert fitting these reasons, also On the contrary, when it is hard to come off and it is necessary to remove it , it is possible to obtain a conflicting effect that it can be easily removed by deforming with will .
Therefore, the present invention has a practically significant effect.

  An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, 1 is a cable duct, and the cable duct 1 is a hollow body continuous in the longitudinal direction formed by bending an end surface into a substantially square shape. A fitting locking body 2 is provided at the center of the rectangular cable duct lower surface portion 1a, the cable duct side surface portions 1b and 1c are formed on the left and right sides thereof, and the cable duct upper surface portion 1d is formed on the upper side thereof.

Then, in the cable duct 1 continuous in the longitudinal direction, holes 3 and 3 are formed in the vicinity of the lower portions of the cable duct side surface portions 1b and 1c, and the cable duct upper surface portion is formed from both side surfaces terminating at the hole portions 3 and 3. A slit 4 is formed during the period 1d, and the hole portions 3 and 3 and the slit 4 are formed as a set and continuously formed at a predetermined interval, whereby the bendable cable duct 1 is obtained.

In addition, as shown in FIG. 2, the fitting locking body 2 is formed with a pair of fitting locking bodies 2 at both end edges of the cable duct lower surface portions 1a and 1a that open and close substantially at the center. A concave locking body 5 and a protruding locking body 6 are formed on the other edge side and the fitting locking body 2 is formed.

Then, the concave locking body 5 is formed by changing the vertical length so that both insertion ends of the concave shaped ends serve as insertion holes, and the insertion portion is substantially shaped like a receiving hole. Next, the engagement locking guide portion 8 is formed on the back side, and the locking engagement portions 9 and 9 are protruded on the back side continuing from the engagement locking guide portion 8 so as to face each other, and the space therebetween is narrowed. formed such, further forms a fitting engagement portion 10 on its inner side, and the shape of the insertion portion of the induction port portion 7 is substantially receptacle shape, recessed retaining body 5 and the projecting holding member 6 Is engaged and locked, the concave locking body 5 and the projecting locking body 6 are opened and closed so that the substantially central portion of the cable duct upper surface portion 1d is the center of the hinge. At that time, the cable duct 1 shown in FIG. The inner side of the hinge is slightly shorter and is formed in a substantially receiving hole shape, so that the direction of rotation of the hinge is Jogakaritometai 6 is easily inserted in a substantially socket-shaped induction port portion 7, thus initial insertion is easily induced.

Further, the other protruding locking body 6 is formed with a protruding insertion part 11 having a substantially tapered tip so that the leading edge of the protruding locking body 6 can be easily inserted into the guide port 7. At the same time, a stepped retaining portion 12 is formed so that the base side of the protruding insertion portion 11 is engaged with the narrowed portion where the retaining portions 9 and 9 protrude. projecting shaped locking member 6 to the stopper portion 10 is formed so as to be engaging in a fitted state.

  Thus, in the extrusion molding of the cable duct 1 having the above-described shape shown in FIG. 3, the cable duct 1 represents an end surface shape in the state of being extruded by an extrusion molding machine, and is slightly opened with the fitting and locking body 2 separated. Extrusion-molded in a substantially trapezoidal shape of the plate-like body in the state of being.

  Here, regarding the material of the cable duct 1 to be extruded, a thermoplastic elastomer in which an olefin rubber (EPR, EPDM) is finely dispersed in a matrix of a soft or hard olefin resin (PP, PE) having deformation recovery ability. Thus, this thermoplastic elastomer is selected in consideration of recoverability by elastic deformation and flexibility characteristics with a predetermined hardness.

And when it is set as the cable duct which can be bent, as shown in FIG. 4, the cable duct lower surface parts 1a and 1a are bent and opened, and the cable duct upper surface part 1d and the cable duct side surface parts 1b and 1c are substantially flat. In this state, as shown in FIG. 5, the hole portions 3 and 3 and the slit 4 are made into one set, and the opening of the hole and the slit are formed by a press machine or the like, and a similar pattern is formed at a predetermined interval in the longitudinal direction. The cable duct 1 having a substantially trapezoidal shape that is formed by being held or extruded is not formed with a hole or slit by a press machine or the like as described above, and the cable duct 1 is in an extruded state as it is. Used as a straight cable duct and selected for each application.
In the figure, reference numeral 13 denotes a V-shaped groove for forming a hollow body that is bent into a substantially quadrangular shape at the end surface. The V-shaped groove 13 is bent from the V-groove 13 to form a hollow body having a substantially quadrangular shape at the end surface.

Thus, when the cable 14 is stored in the cable duct 1, as shown in FIG. 6, with the cable duct 1 turned upside down, the fitting latch 2 is opened wide to store the cable 14, Next, the concave latching body 5 and the projecting latching body 6 of the fitting latching body 2 are brought into contact with the substantially receiving port-shaped guide port part 7 so as to be pivoted from the substantially center of the cable duct upper surface part 1d, From this state, the projecting insertion portion 11 is inserted from the left and right facing directions (in the direction of arrows A and A in the figure) along the substantially receiving port shape of the guiding port portion 7 and further to the fitting engagement guiding portion 8 at the back. The cable duct 1 is inserted and brought into a temporarily closed state in the connection fitting state.

And by applying force from the facing direction of the left and right (arrow A, A direction in the figure) of the cable duct side surface portions 1b and 1c from the temporarily closed connection fitting state of the fitting locking body 2 described above, The projecting locking body 6 is fitted and held in the fitting locking portion 10 so as to spread the retaining locking portions 9 and 9 and is held in the holding shape by the retaining locking portions 9 and 9. Since the fitting and locking body 2 is continuous in the longitudinal direction in this state, when a part of the fitting and locking body 2 is held and the force is applied as it is, the provisional lock of the fitting and locking guiding portion 8 is temporary. It is fitted and locked one after another from the holding to the fitting locking part 10, and when the amount of the cable is large or the wiring of the cable with the bending hook is fitted from the temporarily closed state without being disturbed by the cable. It is easily closed to the locked state, and wiring work becomes easy.

Further, the engagement state of the engagement locking body 2 is such that the engagement engagement guiding portion 8 of the concave engagement body 5 is formed of a thin or soft material, so that deformation is easy to insert, and the back portion thereof. The locking stoppers 9 and 9 and the fitting locking part 10 are made of a thick or hard material so that the deformation is small and does not come off easily when fitted. Since the deformation of 8 is large, it is difficult to deform on the retaining locking portions 9 and 9 and the fitting locking portion 10 side, that is, the fitting locking guiding portion 8 on the tip side and the fitting locking portion 10 side are the same deformation. When the deformation is applied to the fitting engagement guiding portion 8 on the distal end side, it is deformed so as to open from the back end on the fitting engagement portion 10 side. easily disengaged by opening, changing a deformation ratio from this that, also when removing, if necessary, by utilizing the deformation, thin or soft material By opening as turning large induction port portion 7 of the tip of Hamagogakari stop guiding portion 8, to open it deforms greatly Hamagogakari stop guidance unit 8 opens also retaining locking portion 9, 9 about it The retaining latching portion 12 of the projecting latching body 6 can be easily detached from the retaining latching portions 9, 9, and can be easily removed from the state, and since it is continuous in the longitudinal direction, one after another. It can be removed at once.

  Then, the bendable cable duct 1 that has been wired can be bent by being attached to a movable mechanism such as an industrial arm robot while the cable 14 is housed in the cable duct 1 as shown in FIG. use.

  Further, the hole portions 3 and 3 near the lower portions of the cable duct side surface portions 1b and 1c are formed in order to prevent the occurrence of cracks due to bending when the slit 4 is formed by a press or the like. There is no particular concern, and even if it does not form, it will not be immediately affected.

Further, as shown in FIG. 8, the insertion portions of the guide port portions 7 at both ends of the concave locking body 5 are not formed in a substantially receiving port shape as in the above embodiment, but have the same length at both ends. It is used when the concave locking body 5 and the projecting locking body 6 of the body 2 are inserted in a straight line facing each other, and the usage example is such that a conventional grooved cable duct is covered with a lid. What is to be attached is raised, and it is easy to insert and fit the cover so that the cover can be covered. Even if there are a lot of cables to be stored, the cover cannot be easily removed.

  In addition, in the embodiment as the tubular duct 15 shown in FIGS. 9 and 10, the plate-shaped or sheet-shaped plate-shaped duct body 16 has a concave locking body 5 and the other edge side on one end edge side of both end edges. In the state of a flat plate provided with a projecting locking body 6, it is integrally formed by extrusion as in the above embodiment, and the fitting state of the fitting locking body 2 is the same as that in the above embodiment. It is used by being fitted and locked in substantially the same manner, and the plate-like duct body 16 is used so that it can be flexibly bent by changing from a plate-like shape to a sheet-like shape, and a conventional conductive material. By adopting the plate-like duct body 16 as a cable duct, a cable duct capable of blocking noise from outside can be selected and used depending on each application.

In the case where the plate-like duct body 16 is formed into a thin sheet shape , at least the vicinity of the concave locking body 5 and the protruding locking body 6 is formed as a plate shape having a predetermined thickness in the above-described embodiment. The illustration is omitted.

In yet another embodiment, as shown in FIG. 11, it is used for connecting connections such as partitions or partitions, and the side edges provided at the end edges of the partitions 17 are connected to the partitions 17. A concave locking body 5 and a protruding locking body 6 are provided at the distal ends of the connecting bodies 18 and 18 , and the partitions 17 and 17 are connected by connecting the concave locking body 5 and the protruding locking body 6.

Then, the side edge part connection body 18 of this partition 17 is each provided in the both-sides edge part of the plate-shaped body 19 used for a partition or a partition, and as shown in FIG. A concave locking body 5 is formed at the tip, and a projecting locking body 6 is formed at the tip of the other side edge connecting body 18, respectively , and the retaining locking portion of the concave locking body 5 is the same as in the above embodiment. 9 and 9, the stepped locking stopper 12 of the protruding locking body 6 is fitted and locked in a sandwiched manner, so that the required amount of the partition 17 protrudes from the concave locking body 5. Each is connected by the locking body 6 and provided with a leg 20 for self-supporting at the end of the connection, and used as a partition or a partition.

In addition, as described above, the side edge linking body 18 is connected to the side edge linking body 18 having substantially the same shape as that shown in the example of Japanese Patent Application No. 2007-232059 filed by the applicant of the present application. The stop body 5 or the projecting locking body 6 is provided, and the side edge connecting body 18 is provided on both side edges of the plate-like body 19 to be used for connection. By forming the portion 10 with a thicker or hard material, even when a large force is applied when used as a partition or a partition , the deformation of the fitting engagement guiding portion 8 on the distal end side is great, so Deformation does not occur on the engaging portions 9 and 9 and the fitting engaging portion 10 side, and therefore the deformation on the fitting engaging portion 10 side is small. There is no disconnection, and the locking stoppers 9 and 9 lock the locking stopper 12 in a pinched manner. Without departing more fitting locking by, connected in series such as partition or Patishon, as a connecting member for fitting the holding it can particularly effectively used.

Each connecting side edges connecting body 18 provided on the plate-like body 19 is connected connected substantially similarly fitted locking and that of the embodiments described above, also removed are similarly when removing Therefore, it can be connected and removed .
