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.

  Furthermore, a plate-like connector such as a panel disclosed in Patent Document 3 is deformed by collision with a person having substantially the same problem as the connection locking structure for a bendable cable duct disclosed in Patent Document 2, and assembling a partition. However, there was a need for improvement.

  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 provides one concave locking body of a fitting locking body, the front end surface of which is substantially U-shaped, and both ends of the substantially U-shaped ends. Forming a fitting engagement guiding portion on the back side continuing from the guiding opening portion, a retaining locking portion on the back side continuing from the fitting locking guiding portion, and The guide port portion is formed of a soft, thin or wide mouth so that a fitting lock portion is formed on the inner side and the deformation width of the guide port portion is increased to facilitate insertion of the projecting lock body. On the contrary, by making the fitting locking portion hard or thick so that the protruding locking body is difficult to come off from the fitting locking portion on the back side, the deformation width is reduced. Since the protruding locking body is formed corresponding to the fitting locking portion,
When a plate-shaped cable duct is closed to form a cable duct of a predetermined shape, or the lid of the cable duct can be opened / closed or deployed, or a coupling connection such as a partition or partition is induced to facilitate insertion and fitting. On the contrary, it is configured to be difficult to come off by mating locking.

The present invention is configured so that an effective effect can be obtained by the above-described means, and in particular, fitting engagement for opening and closing or fitting connection such as opening and closing of a cable duct lid or fitting connection such as a partition and partition. A pair of fitting locking bodies that form a concave locking body on one side of the fitting locking body and a protruding locking body on the other side, respectively. The stationary body has a substantially U-shaped front end surface, and both ends of the substantially U-shaped are formed as guide ports, and a fitting and locking guide is formed on the back side following the guide port. The locking engagement portion is formed on the rear side of the fitting engagement guide portion, and the engagement locking portion is formed further on the rear side. In order to facilitate insertion of the shaped locking body, the guide port is made soft, thin or wide, and conversely, the fitting on the back side thereof As projecting holding member from the engaging portion is less likely to come off, the fitting engagement portion by a rigid or thick, formed by reducing its deformation width,
Further, the other protruding locking body has a protruding insertion portion formed substantially in a tapered shape so that a tip end edge portion of the protruding locking body corresponds to insertion into the guide port portion, and the protruding insertion A stepped retaining lock portion is formed on the base side of the portion so as to correspond to the retaining lock portion, and is formed to correspond to the fitting lock portion. Because
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.

  Then, when the fitting locking portion is completely held by the fitting locking portion from the temporarily held state in which the protruding locking body is restricted in the fitting locking guiding portion, the fitting locking portion and the retaining locking Because the part is hard or thick and the deformation width is small, the fitting locking part does not cause insertion displacement from the temporarily held state where the protruding locking body is regulated in the fitting locking guiding part Can be easily inserted and fitted, and when the projecting latching body is inserted and held from the retaining latching part to the fitting latching part at the back, the cable duct or partition which is the main body side of the mating latching body, Even if it is closed, it can be easily and easily closed even when it is incomplete, so that the work efficiency can be improved and the work cost can be reduced to reduce the cost.

Further, when the protruding locking body is removed from the fitting locking body from the concave locking body, the guide opening and the fitting locking guide are soft, thin or wide, The guide port portion can be greatly deformed and opened so as to be largely folded together with the fitting locking guiding portion, thereby opening the retaining locking portion, and the protruding locking body is easily detached from the fitting locking portion, The protrusion-like locking body can be pulled out with a little force, and deformation under general usage conditions does not open like this, so it is difficult to come off, and it is easy to insert from these, and conversely 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.
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, holes 3 and 3 are formed in the vicinity of the lower portions of the cable duct side surface portions 1b and 1c, and a slit 4 is formed between the both side surfaces ending with the hole portions 3 and 3 and the cable duct upper surface portion 1d. Further, the cable duct 1 that is continuous in the longitudinal direction is formed as a cable duct 1 that can be bent by forming the hole portions 3 and 3 and the slits 4 as a set with a predetermined interval.

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

  The concave locking body 5 is formed as a guide port 7 formed by changing the vertical length so that both ends of the recess are the insertion ports and the insertion portion is substantially in the shape of a receiving port, and continues from the guide port 7. On the back side, a fitting / locking guiding part 8 is formed, and on the back side continuing from the fitting / locking guiding part 8, retaining locking parts 9, 9 are formed to face each other, and further on the back side. The shape in which the fitting locking part 10 is formed and the insertion part of the guide port part 7 has a substantially receiving hole shape is such that when the concave locking body 5 and the projecting locking body 6 are fitted together, the upper part of the cable duct The concave locking body 5 and the projecting locking body 6 are opened and closed so that the substantially central portion of 1d is the center of the hinge. At that time, the inside of the cable duct 1 shown in FIG. Thus, the protruding locking body 6 when opening and closing in the above-described hinge shape follows the substantially receiving port shape of the guide port portion 7 of the concave locking body 5. It is inserted, thus to facilitate the initial insertion.

  Further, the other protruding locking body 6 is formed with a protruding insertion portion 11 having a substantially tapered end so that the leading edge of the protruding locking body 6 can be inserted into the guide port 7. On the base side of the protruding insertion portion 11, a stepped locking stopper 12 is formed so as to correspond to the locking locking portions 9, 9, and the protruding locking body 6 The fitting locking portion 10 is formed so as to substantially correspond in the 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 7 so as to rotate in a hinge shape from the approximate center of the cable duct upper surface portion 1d. From that state, a substantially tip-shaped tapered insertion portion 11 is inserted and inserted along the substantially receiving port shape of the guide port portion 7, and further inserted to the fitting engagement guide portion 8 at the back of the projection insertion portion 11. Then, the cable duct 1 is temporarily closed.

  Then, by applying force from the left and right (arrows A and A directions in the figure) of the side surfaces 1b and 1c of the cable duct from the temporarily closed locking state of the fitting locking body 2 described above, The stopper 6 reaches the fitting latching portion 10 so as to spread out the retaining latching portions 9 and 9, and is fitted and held, and since it is continuous in the longitudinal direction, it is partially fitted and held. The fitting and holding of the fitting locking portion 10 and the temporary holding and holding of the fitting and locking guide portion 8 are held in succession, and when the amount of cable is large or the wiring of the cable with a bending wrinkle is also The cable is easily closed without being obstructed by the cable, and wiring work is facilitated.

  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 deformation is small, they do not come off easily when fitted, and when they are removed as necessary, By opening so as to rip from the guide opening 7 at the tip of the soft material fitting and engaging guiding portion 8, the fitting and engaging guiding portion 8 is greatly deformed and opened. Since 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 is continuous in the longitudinal direction. It can be removed one after another.

  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 have the same length as both ends that are not formed in a substantially receiving port shape as in the above embodiment. It is used when the body 2 is inserted facing each other in the front, and an example of its use is that a conventional groove-shaped cable duct can be put on a lid so that the lid can be covered by using it. Therefore, even if there are many cables to be accommodated due to the effects described above, it is possible to provide a cover that 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.

  When the thin duct-like plate body 16 is used, at least the vicinity of the concave locking body 5 and the projecting locking body 6 is formed as a plate having a predetermined thickness in the above embodiment. However, in particular, illustration was omitted.
