Mode for Carrying Out the Invention

[0010] Embodiment Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the invention according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are essential as means for solving the problems. For the sake of clarity of explanation, the following description and drawings have been appropriately omitted and simplified. In each drawing, the same elements are denoted by the same reference numerals, and duplicate explanations are omitted as necessary.

[0011] (Explanation of the connector removed by the connector removal jig according to the embodiment) FIG. 1 is a schematic view of a first component and a second component coupled by a connector according to an embodiment. With reference to FIG. 1, the connector removed by the connector removal jig according to the embodiment will be described.

[0012] The connector according to the embodiment is used, for example, in a bellows that connects the door of a hatchback door of a vehicle and the vehicle body. The wiring of the drive recorder installed on the hatchback door is passed through the bellows to improve the appearance and prevent it from being pinched when the door is closed. When wiring, the connectors at both ends of the bellows are removed, but since there are several locks at different positions and it is difficult to release them by pressing them simultaneously. Usually, a pick tool with an L-shaped tip is used to release the locks one by one, and the difference in release is held down with a finger or an object so that it does not return.

[0013] <x As shown in FIG., the connector according to the embodiment includes a first component 101, a second component 102, a connector 103, and an engaging portion 104. <x <x

[0014] <x The first component is a bellows through which wiring is passed. For example, the first component is made of an elastic material such as rubber and can be deformed according to the opening and closing of the door. <x <x

[0015] <x The second component is a vehicle door, particularly a hatchback door or the vehicle body. The second component is made of metal and does not deform. <x

[0016] The connector 103 is attached to the first component 101. The connector 103 is made of metal or the like and does not deform easily. The connector 103 has multiple engaging portions 104 that engage with the second component 102. The number of engaging portions 104 is, for example, 3 or 4. Since the connector 103 is elliptical, track-shaped, or circular, the engaging portions 104 are provided at multiple locations along the circumference of the connector.

[0017] The engaging portion 104 is preferably formed by a claw that passes through a hole in the second component 102. By pressing the claw, the engaging portion deforms and the engagement is released from the hole. By deforming all of the multiple engaging portions, the connector 103 is released from the second component 102.

[0018] (Description of the connector removal tool according to the embodiment) Figure 2 is a side view of the connector removal tool according to the embodiment. Figure 3 is a top view of the connector removal tool according to the embodiment. Figure 4 is a cross-sectional view of the head of the connector removal tool according to the embodiment. Figure 5 is a first side view of the wedge of the connector removal tool according to the embodiment. Figure 6 is a top view of the wedge of the connector removal tool according to the embodiment. Figure 7 is a second side view of the wedge of the connector removal tool according to the embodiment. Figure 8 is a first side view of the wedge of the connector removal tool according to the embodiment. Figure 9 is a cross-sectional view taken along line IX-IX in Figure 8. Figure 10 is a top view of the wedge of the connector removal tool according to the embodiment. Figure 11 is a second side view of the wedge of the connector removal tool according to the embodiment. The connector removal tool according to the embodiment will be described with reference to Figures 2 to 11.

[0019] As shown in Figures 2 and 3, the connector removal tool 200 comprises a body 201, a head 202, and a wedge 203.

[0020] The abdomen 201 is stretchable in one direction. The abdomen 201 is made of plastic or similar material and is flexible. The abdomen 201 can form a ring. The abdomen 201 has a flattened cross-section perpendicular to one direction; that is, the abdomen 201 has a flat portion. Furthermore, the abdomen 201 has multiple protrusions 205 projecting from its bellows-like flattened shape in one direction.

[0021] The head portion 202 is provided at one end of the abdomen portion 201. The head portion 202 includes an annular portion 204, which includes a retaining portion 401 and a claw portion 402, as shown in Figure 4(a). The other end of the abdomen portion 201 passes through the annular portion 204. The retaining portion 401 is elastic. The claw portion 402 engages with one of the projections 205 of the abdomen portion 201. The abdomen portion 201 is locked in place by the retaining portion 401, and the size of the ring is determined.

[0022] As shown in Figure 4(b), when the retaining portion 401 is pushed up, the claw portion 402 detaches from the projection 205 of the abdomen 201, and the size of the ring formed by the abdomen 201 changes.

[0023] Multiple wedges 203 are attached to the abdomen 201. When viewed from above, the wedge directions of the multiple wedges 203 face inward towards the ring. That is, the multiple wedges 203 face in the same direction from one side of the abdomen. As shown in Figures 5, 6, and 7, the wedge 203 has an annular portion 501 into which the abdomen 201 is inserted.

[0024] The annular portion 501 of the wedge 203 is provided with a protrusion 901, as shown in Figure 9, which is the IX-IX section in Figure 8. As shown in Figures 11 and 12, this protrusion 901 is located at the center of the wedge 203 and engages with the projection 205 of the abdominal portion 201. The engagement of the protrusion 901 with the projection 205 of the abdominal portion 201 locks the wedge 203 in place.

[0025] The above configuration provides a connector removal tool that can remove multiple engagement parts at once.

[0026] (Description of the connector removal method according to the embodiment) Figure 12 is a side view showing the connection between the connector and the second component according to the embodiment. Figure 13 is a top view of the connector according to the embodiment. Figure 14 is a side view showing preparation for applying the connector removal tool to the connection between the connector and the second component according to the embodiment. Figure 15 is a top view showing preparation for applying the connector removal tool to the connection between the connector and the second component according to the embodiment. Figure 16 is a side view showing the connector removal tool being applied to the connection between the connector and the second component according to the embodiment. Figure 17 is a top view showing the connector removal tool being applied to the connection between the connector and the second component according to the embodiment. Figure 18 is a side view showing the connection between the connector and the second component being released according to the embodiment. The connector removal method according to the embodiment will be described with reference to Figures 12 to 18.

[0027] As shown in Figure 12, the connector 103 and the second component 102 according to this embodiment are connected by a claw-shaped engaging portion 104. As shown in Figure 13, the connector 103 includes the engaging portion 104. The engaging portion 104 is inserted into the second component 102, and the second component 102 is connected to the connector 103.

[0028] As shown in Figure 14, prepare to apply the connector removal tool 200 to release this connection. As shown in Figure 15, wrap the abdomen 201 around the connector 103. At this time, align the engagement portion 104 and the wedge 203. The wrapped abdomen 201 is then inserted into the annular portion of the head 202 and prepared to be tightened.

[0029] In this case, as shown in Figure 16, it is preferable that the head 202 has a recess 202a on either the top surface 1501 or the side surface 1502 where the operator's fingers can be placed. The presence of the recess makes it easier to hold the head 202 with one hand and pass the abdomen 201 through the head 202 with the other hand.

[0030] As shown in Figures 16 and 17, when the abdomen 201 is pulled, the loop of the abdomen 201 becomes smaller. At this time, if there is a grooved surface 202b on the lower surface 1601 of the head 202, it will hold down the second part 102 and not move, making it easier to pull the abdomen 201. A grooved surface may also be provided on the upper surface 1602 of the head 202 so that a finger can grip it. When the loop is narrowed, the wedge 203 comes into contact with the engaging part 104 and disengages from the second part 102. One of the multiple wedges 203 is driven into one of the multiple engaging parts 104, disengaging from the connector 103.

[0031] As shown in Figure 18, when the connector 103 is pulled upward away from the second component 102, the connector 103 detaches from the second component 102.

[0032] Thus, a connector removal method is provided that allows multiple engagement parts to be removed at once.

[0033] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. [Explanation of symbols]
