FIG. FIG. 6 is an explanatory view showing the resin component 3.

  As shown in FIGS. 5 and 6, the resin component 3 includes a main body 10, a magnetic body pressing piece 21, a support shaft 31, a bearing portion 32, a retaining portion 33, an engaging portion 41, and an engaged portion 46. It has a prepared structure.

  A storage chamber 11 is formed inside the main body 10, and the divided magnetic body 5 is stored in the storage chamber 11 (see FIG. 2). In addition, two notches 13 and 13 are formed in the main body portion 10.

  The magnetic body pressing piece 21 is a leaf spring-like one extending from the main body 10 and slightly extends toward the storage chamber 11, whereby the divided magnetic body 5 is stored in the storage chamber 11. The magnetic body pressing piece 21 has a structure that presses the divided magnetic body 5 with elastic deformation.

  The support shaft 31 and the bearing portion 32 are provided in the other resin component 3 while the support shaft 31 provided in one resin component 3 is inserted into the bearing portion 32 provided in the other resin component 3. The support shaft 31 is inserted into a bearing portion 32 provided on one resin component 3, thereby connecting the two resin components 3 and 3.

  The retaining portion 33 is a leaf spring that extends from the main body portion 10. A retaining protrusion 34 is formed on the outer surface of the retaining portion 33, and when the retaining force 34 receives an external force, the retaining portion 33 is elastically deformed to be retained. 34 is configured to be retracted inside the main body 10. The function of the retaining portion 33 will be described in detail later.

  The engaging portion 41 and the engaged portion 46 engage the engaging portion 41 provided in one resin component 3 with the engaged portion 46 provided in the other resin component 3, and the other resin By engaging the engaging part 41 provided in the part 3 with the engaged part 46 provided in one resin part 3, the two resin parts 3 and 3 connected in an openable / closable state are closed. It is to be fixed.

  The engaging portion 41 includes a folded portion 42 formed in a substantially U shape. That is, as shown in FIG. 5B, the folded portion 42 is a base portion 42a that protrudes rightward in the drawing from the engaged portion 46, and is bent downward from the right end of the drawing of the base portion 42a and extends downward in the drawing. Part 42b, a descending part 42b bent from the lower end in the figure and extending to the right in the figure, and an ascending part 42d bent from the right end in the figure in the transverse part 42c and extending obliquely upward to the right. The overall shape is substantially U-shaped.

  Further, a support portion 43 projects from an intermediate portion of the folded portion 42 (near the upper end of the ascending portion 42d in FIG. 5B), and an operation is performed at the tip of the support portion 43 (the right end in FIG. 5B). A portion 44 is formed. The folding portion 42 is elastically deformed when a pressing force is applied from the operation portion 44 side toward the support portion 43 side, and the upper end of the ascending portion 42d approaches the upper end of the descending portion 42b along with this elastic deformation. When the pressing force is no longer applied, the elastic deformation is restored and the folded portion 42 returns to its original form.

  Furthermore, a stepped engagement step 45 is formed at the tip of the folded portion 42 (the upper end of the ascending portion 42d in FIG. 5B). Further, the width W1 of the support portion 43 is narrower than the width W2 of the folded portion 42 (see FIG. 6).

  The engaged portion 46 is formed with a storage portion 47 having an internal space in which the folded portion 42 can be stored when the engagement portion 41 is engaged. Two collar portions 48 are formed at opposing positions on the inner space side of the storage portion 47. Further, as shown in FIG. 6, the width W3 of the internal space of the storage portion 47 is wider than the width W2 of the folded portion 42. Further, in the internal space of the storage portion 47, the width W4 between the two flange portions 48, 48 is narrower than the width W2 of the folded portion 42 and wider than the width W1 of the support portion 43. .

  Next, a method of connecting the two resin parts 3 and 3 as described above will be described with reference to FIG. FIGS. 7A, 7B, and 7C are explanatory diagrams of a method of connecting two resin parts 3 and 3 according to the present embodiment.

  First, as shown in FIG. 7A, the user faces the support shaft 31 of one resin component 3 to the retaining portion 33 of the other resin component 3, and the support shaft 31 of the other resin component 3 The two resin parts 3 and 3 are arranged so as to face the retaining part 33 of the resin part 3.

  The support shaft 31 of one resin component 3 and the retaining portion 33 of the other resin component 3 are in contact with each other, and the support shaft 31 of the other resin component 3 and the retaining portion 33 of one resin component 3 are in contact with each other. When the resin parts 3 and 3 are brought close to each other and the support shaft 31 is pressed against the retaining protrusion 34 of the retaining portion 33, both retaining portions 33 are arranged in the inner direction of the main body portion 10 as shown in FIG. Retracted in the (Z direction).

  In this state, the user relatively moves one resin component 3 in the left direction (X direction) in the drawing and the other resin component 3 in the right direction (Y direction) in the drawing, thereby 31 is inserted into the other bearing portion 32, and the other support shaft 31 is inserted into the one bearing portion 32.

  Then, when the support shaft 31 reaches a position over the retaining protrusion 34, as shown in FIG. 7C, the shape of the retaining portion 33 that has been elastically deformed is restored, and the retaining protrusion 34 is restored to its original position. Return to. As a result, both the support shafts 31 are sandwiched between the retaining protrusion 34 and the bearing portion 32 and are held so as not to come out of the bearing portion 32.

  When the two resin parts 3 and 3 are connected via the support shaft 31 and the bearing portion 32 in this way, the resin parts 3 and 3 can be opened and closed with the two support shafts 31 and 31 as the rotation center. Will be linked.

  Next, a method for attaching the cable attaching tool 1 to the cable and a method for removing it from the cable will be described.

  When the cable mounting tool 1 is mounted on the cable, first, the cable mounting tool 1 is opened, and the cable is inserted into the magnetic grooves 7 and 7 on the inner peripheral side of the divided magnetic bodies 5 and 5. Inserted into the cable with two resin parts 3 and 3 in that state.

  At this time, the engaging portion 41 of the one resin component 3 is elastically deformed by the folding portion 42 coming into contact with the two flange portions 48, 48 of the engaged portion 46 of the other resin component 3, and the support portion When 43 passes between the two collar portions 48, 48, it enters the storage portion 47 of the engaged portion 46. Similarly, the engaging portion 41 of the other resin component 3 is elastically deformed and supported by the folded portion 42 being in contact with the two flange portions 48 and 48 of the engaged portion 46 of the other resin component 3. The part 43 enters the storage part 47 of the engaged part 46 by passing between the two flange parts 48, 48. Thereafter, when both engaging portions 41 enter a predetermined position in the internal space of the storage portion 47 of the engaged portion 46, both folded portions 42 that have been elastically deformed are restored. As a result, both the engaging step portions 45 engage with the two flange portions 48 and 48, respectively, and are locked.

  When the folded portion 42 enters the storage portion 47 in this way, as shown in FIG. 3B, the folded portion 42 provided on one resin component 3 (the folded portion 42R on the right side in FIG. 3B). ) Is in contact with a part 49 (49R) of the storage portion 47 (the storage portion 47R on the right side in FIG. 3B) provided in the other resin component 3 on the left side (FIG. 3). The displacement in the direction of the arrow P shown in 3 (b) is regulated. Similarly, the folded portion 42 provided on the other resin component 3 (the folded portion 42L on the left side in FIG. 3B) also has a storage portion 47 (FIG. 3B) in which the descending portion 42b is provided on the one resin component 3. 3 (b) is in contact with a portion 49 (49L) of the storage portion 47L on the left side, and therefore the displacement to the right (in the direction of arrow Q shown in FIG. 3B) is restricted. .

  Moreover, contrary to the above, the folded portion 42 (folded portion 42R on the right side in FIG. 3B) provided on one resin component 3 is moved to the right (arrow Q shown in FIG. 3B). The folded portion 42 (folded portion 42L on the left side in FIG. 3B) provided on the other resin component 3 is moved to the left (arrow shown in FIG. 3B). When it is likely to be displaced in the (P direction), the portions 49 (49R, 49L) of the two storage portions 47 (47R, 47L) come into contact with each other, whereby the displacement of the folded portion 42 as described above is caused. regulate.

  That is, one of the storage portions 47 (the storage portion 47L shown in FIG. 3B) regulates the movement of the folded portion 42 (the folded portion 42L shown in FIG. 3B) on the inner side and the other on the outer side. The movement of the storage portion 47 (the storage portion 47R shown in FIG. 3B) is restricted, and the other storage portion 47 (the storage portion 47R shown in FIG. 3B) is folded inside (see FIG. 3B). 3 (b) restricts the movement of the folded portion 42R) and restricts the movement of one of the storage portions 47 (the storage portion 47L shown in FIG. 3 (b)) on the outside, whereby the resin component 3 3 has a structure that is extremely difficult to displace in both the left and right directions (both directions of arrows P and Q shown in FIG. 3B).

  Therefore, with the structure as described above, the two resin parts 3 in the locked state can be suppressed because the two engaging parts 41, 41 and the two engaged parts 46, 46 can be prevented from shifting in the horizontal direction in the figure. The rattling of 3 can be prevented. Further, even if an unexpected external force is applied to the resin parts 3 and 3 in the locked state, the resin parts 3 and 3 are not displaced, so that both support portions 43 can pass between the two flange portions 48 and 48. There is no possibility that the lock is inadvertently released due to the displacement to the position.

  On the other hand, when the cable mounting tool 1 mounted on the cable in such a procedure is removed from the cable, the two operation units 44 and 44 are pressed with a finger in the opposite direction in the same direction as the axial direction of the cable. To do. Then, as both engaging portions 41 are elastically deformed, both engaging step portions 45 are separated from the two hook portions 48, 48 engaged, and the engagement is released.

  In this way, the engagement of both the engagement step portions 45 is released, and both the support portions 43 are displaced to a position where they can pass between the two flange portions 48, 48, so that the two resin parts 3 and 3 are in an unlockable state that can be freely opened and closed. Thereafter, the cable mounting tool 1 can be removed from the cable by opening the two resin parts 3 and 3 to open the cable mounting tool 1.

  In the case of the cable mounting tool 1 as described above, when the user intends to change from the locked state to the unlocked state, the user presses the two operating portions 44 and 44 with his / her fingers and simultaneously presses the two engaging portions. The two engagements by the portions 41 and 41 and the two engaged portions 46 and 46 can be released simultaneously. Therefore, for example, even when the cable mounting tool 1 is removed from the cable by groping, the work of removing the cable mounting tool 1 can be easily performed as compared with the conventional product.

  Further, in the case of such a cable mounting tool 1, the structure of the lock mechanism composed of the two engaging portions 41, 41 and the two engaged portions 46, 46 can be obtained even when the cable mounting tool 1 is rotated 180 degrees. It becomes the same structure. Therefore, when attaching the cable mounting tool 1 to the cable, even if the attaching direction is reversed by 180 degrees, no difference appears in the opening / closing operation method, and the same operation method can be used to change from the closed state to the open state. .

  Therefore, with such a cable mounting tool 1, the opening / closing operation can be performed without being aware of the direction in which the cable mounting tool 1 is attached, and compared with the case where the lock mechanism is not 180-degree rotationally symmetric. It is possible to make it easier to perform the opening and closing operation.

  Moreover, according to the cable mounting tool 1, a pair of divided magnetic bodies are formed by the two resin parts 3 and 3 having the same shape. Therefore, when manufacturing a pair of divided magnetic body cases, only the resin component 3 needs to be manufactured. Therefore, a mold for molding the resin component 3 may be prepared.
