Description

Technical Field

[0001] The present invention relates to a dust-proof cover for a connector and a dust-proof structure of a connector.

Background Art

[0002] When dust adheres to the terminals inside a connector connected to the end of a wire harness, there is a possibility of poor contact when connecting to other devices. Therefore, until connecting to other devices, the connector is covered with a dust-proof cover to prevent the adhesion of dust and the like.

[0003] Conventional dust-proof measures for connectors are to cover the connector with a bag body and then wind the periphery of the bag body with a slit tape so that the connector does not fall out of the bag body. However, when transporting a wire harness equipped with a connector covered with a bag body, the slit tape may peel off, resulting in a decrease in dust-proof performance. Also, when removing the bag body from the connector, the slit tape may adhere to the operator's gloves or the like. Therefore, there is a need for a dust-proof cover that can be easily removed while dust-proofing the connector.

[0004] Patent Document 1 discloses a dust-proof protective cover that is placed on an attachment member connected to a main member and removed during use. The dust-proof protective cover is formed of a bag with one end open, and an adhesive tape with a release paper attached to the inner surface of the open end thereof is attached. A notch is provided at one side end of the open end, and the notch extends from the upper end beyond the lower end position of the adhesive tape to the side end. Then, the bag is placed on the attachment member from the open end, passed through the connection portion of the attachment member to the main member through the notch where the adhesive tape is not attached, and in this state, the release paper is peeled off and the open end is closed with an adhesive. When removing, when the bag is pulled in the outward direction, the bag is torn and removed through the notch where the above connection portion is exposed. Also, the bag of Patent Document 1 is formed into a bag with one end open by folding a rectangular resin sheet in half and heat-sealing both sides thereof to form a closed portion.

[0005] [Patent Document 1] Japanese Patent Publication No. 2000-21489 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, in the protective cover described in Patent Document 1, both sides of the resin sheet are heat-sealed to form a closed section, and the opening is further closed using adhesive tape, resulting in multiple joining means and a complex structure.

[0007] This invention has been made in view of the problems of the prior art. The object of this invention is to provide a dust cover for a connector and a dust cover structure for a connector that can provide dust protection with a simple structure. [Means for solving the problem]

[0008] A dust cover for a connector according to a first aspect of the present invention is a cover that is fitted to cover a connector and protect the connector from dust. The dust cover for a connector comprises a bag having an opening, and the connector is housed inside the bag to cover the entire connector. The opening of the bag is provided around the wires connected to the connector, and a part of the bag is joined with only one type of joint, so that when the connector is housed inside the bag, the width of the opening located around the wires is smaller than the width of the connector.

[0009] A dustproof connector structure according to a second aspect of the present invention comprises a connector to which electric wires are connected, and a dustproof connector cover according to the first aspect, which is fitted to cover the connector and protect the connector from dust. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a dustproof cover for a connector and a dustproof structure for a connector that can implement dustproof measures with a simple structure. [Brief explanation of the drawing]

[Figure 5] This is a schematic plan view showing a dust cover for a connector according to the fifth embodiment. [Figure 6] This is a schematic plan view showing a dust cover for a connector according to the sixth embodiment. [Modes for carrying out the invention]

[0012] The dust cover for the connector and the dustproof structure of the connector according to this embodiment will be described in detail below with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0013] The dust cover for connectors in this embodiment is a cover that is attached to a connector to which electric wires are connected, and protects the connector from dust. Such a connector can be, for example, a connector connected to the end of a wire harness.

[0014] The dust-proof cover for the connector is made of a flexible sheet and has a bag body with an opening on one side. The material of the sheet constituting the bag body is not particularly limited, and for example, resins such as polyolefin or polyvinyl chloride, or paper can be used. The sheet may be transparent, translucent, or opaque. However, it is preferable that the sheet constituting the bag body is transparent so that the state of the connector can be visually confirmed after covering the connector with the dust-proof cover for the connector.

[0015] When the dust-proof cover for the connector is attached to the connector, the connector is housed inside the bag body, and an opening of the bag body is provided around the electric wire connected to the connector. At this time, by joining a part of the bag body with only one type of joint part, the width of the opening located around the electric wire is smaller than the width of the connector in the state where the connector is housed inside the bag body. Hereinafter, the dust-proof cover for the connector of each embodiment will be described in detail.

[0016] [First Embodiment] As shown in FIG. 1A, the dust-proof cover 1 for the connector of the present embodiment has a bag body 2 that is substantially rectangular in plan view. The bag body 2 is substantially rectangular and includes a front surface sheet 3 and a back surface sheet 4 that are substantially the same size. A closed bottom portion 5 is provided at the upper end in the longitudinal direction (Y direction) of the bag body 2, and an opening 6 is provided at the lower end.

[0017] As will be described later, the bag body 2 is formed by folding a single rectangular sheet in half, and the front surface sheet 3 and the back surface sheet 4 are formed by overlapping the upper side and the lower side of the rectangular sheet. And the folded-back portion of the rectangular sheet is the bottom portion 5.

[0018] At one end 21 on the left side and the other end 22 on the right side in the width direction (X direction) of the bag body 2, a first joint portion 11 is continuously provided from the bottom portion 5 of the bag body 2 toward the opening 6. The first joint portion 11 is a portion formed by joining the front sheet 3 and the back sheet 4. The joining method of the front sheet 3 and the back sheet 4 is not particularly limited and can be performed by heat welding or an adhesive.

[0019] The first joint portion 11 has a first joint portion 111 on one end side near one end 21 of the bag body 2 and a second joint portion 112 on the other end side near the other end 22 of the bag body 2. There is a portion where the front sheet 3 and the back sheet 4 are not joined between the first joint portion 111 on one end side and one end 21, and there is also a portion where the front sheet 3 and the back sheet 4 are not joined between the second joint portion 112 on the other end side and the other end 22.

[0020] The first joint portion 111 on one end side and the second joint portion 112 on the other end side extend substantially parallel from the bottom portion 5 of the bag body 2 toward the opening 6. Therefore, the one end 21 and the other end 22 of the bag body are in a closed state by the first joint portion 111 on one end side and the second joint portion 112 on the other end side. And the distance between the first joint portion 111 on one end side and the second joint portion 112 on the other end side is larger than the width W2 of the connector 300.

[0021] On the bag body 2, a second joint portion 12 is provided so as to continuously reduce the diameter from the opening side end portions 113, 114 of the first joint portion 11 toward the opening 6. The second joint portion 12 is also a portion formed by joining the front sheet 3 and the back sheet 4. The joining method of the front sheet 3 and the back sheet 4 is not particularly limited and can be performed by heat welding or an adhesive. However, the joining methods of the first joint portion 11 and the second joint portion 12 are the same.

[0022] The second joint 12 has a second joint 121 on one end side, located near one end 21 of the bag body 2, and a second joint 122 on the other end side, located near the other end 22 of the bag body 2. Between the second joint 121 on one end side and the one end 21, there is a portion where the surface sheet 3 and the back sheet 4 are not joined, and between the second joint 122 on the other end side and the other end 22, there is also a portion where the surface sheet 3 and the back sheet 4 are not joined.

[0023] Furthermore, the second joint portion 121 at one end extends from the opening end 113 of the first joint portion 111 at one end toward the opening 6, inclined toward the other end (to the right on the X-axis). Similarly, the second joint portion 122 at the other end extends from the opening end 114 of the first joint portion 112 at the other end, inclined toward the one end (to the left on the X-axis) toward the opening 6. As a result, the second joint portion 121 at one end and the second joint portion 122 at the other end gradually approach the opening 6 from the opening ends 113 and 114 of the first joint portion 111. Consequently, the second joint portion 122 continuously decreases in diameter from the opening ends 113 and 114 of the first joint portion 111 toward the opening 6.

[0024] An opening 6 is formed between the open end 123 of the second joint 121 at one end and the open end 124 of the second joint 122 at the other end. In the width direction of the bag body 2, the distance between the open end 123 of the second joint 121 at one end and the open end 124 of the second joint 122 at the other end is smaller than the width W2 of the connector 300. The open end 123 of the second joint 121 at one end and the open end 124 of the second joint 122 at the other end are located near the electric wire 301 connected to the connector 300. Therefore, the opening 6 of the bag body 2 is provided around the electric wire 301.

[0025] In the connector dust cover 1, a closed space is formed by the surface sheet 3, the back sheet 4, and the first joint portion 11 and the second joint portion 12. Furthermore, the connector 300 and a portion of the electric wire 301 are housed inside this closed space. As a result, the connector 300 is protected from dust by the connector dust cover 1, which prevents dust and other debris from adhering to the inside of the connector 300. In addition, with the connector 300 housed inside the connector dust cover 1, the width W1 of the opening 6 located around the electric wire 301 is smaller than the width W2 of the connector 300. Therefore, when transporting a wire harness equipped with the connector 300 covered by the connector dust cover 1, it is possible to prevent the connector dust cover 1 from falling off the connector 300.

[0026] Then, when the wire harness equipped with the connector covered by the connector dust cover 1 is transported and installed in a vehicle or the like, the connector dust cover 1 is removed from the connector 300. When removing the connector dust cover 1, for example, a worker grasps the vicinity of the bottom 5 of the connector dust cover 1 and pulls it up, causing the connector 300 to come into contact with the second joint 12. Further pulling up the connector dust cover 1 causes the second joint 12 to break, and the surface sheet 3 and back sheet 4 to tear apart. After that, the connector dust cover 1 can be removed from the connector 300 by pulling it up even further.

[0027] Next, the manufacturing method of the dust cover 1 for the connector of this embodiment will be described. First, a rectangular sheet 20 is prepared as shown in Figure 1B. Then, the lower half of the rectangular sheet 20 is placed on the lower surface of the connector 300, and the rectangular sheet 20 is folded in half, and the upper edge 23 and lower edge 24 of the rectangular sheet 20 are overlapped as shown in Figure 1C.

[0028] Next, a first joint 11 and a second joint 12 are formed on the folded rectangular sheet 20. If the first joint 11 and the second joint 12 consist of heat-sealed portions formed by heat-welding the rectangular sheet 20, the first joint 11 and the second joint 12 can be formed by clamping the outer surface of the folded rectangular sheet 20 and heating and melting it. Heating and melting the rectangular sheet 20 can be done, for example, using a heat sealer or a hand sealer. Alternatively, if the first joint 11 and the second joint 12 consist of an adhesive, the first joint 11 and the second joint 12 can be formed by applying a liquid adhesive to the inner surface of the folded rectangular sheet 20 and then allowing it to harden. The adhesive can be applied, for example, using a glue gun. Through such a simple process, a dust cover 1 for connectors can be manufactured.

[0029] As described above, the dust cover 1 for the connector of this embodiment has a surface sheet 3 and a back sheet 4 joined at a first joint 11 and a second joint 12, and furthermore, the first joint 11 and the second joint 12 are formed using only one method. Therefore, dust protection measures for the connector 300 can be implemented with a simple structure while suppressing the generation of waste from the dust cover 1 for the connector.

[0030] [Second Embodiment] Next, the dust cover 1A for the connector according to the second embodiment will be described in detail with reference to the drawings. In the following description, the same reference numerals are used for components identical to those in the first embodiment, and redundant descriptions are omitted.

[0031] As shown in Figures 2A to 2C, the dust cover 1A for the connector in this embodiment comprises a bag-like body 2 that is substantially rectangular when viewed from above. The bag-like body 2 comprises a surface sheet 3 and a back sheet 4 that are substantially rectangular in shape and of substantially the same size.

[0032] The upper end of the bag body 2 in the longitudinal direction (Y direction) is provided with a closed bottom 5, and the lower end is provided with an opening 6. The entire left end 21 and the entire right end 22 of the bag body 2 in the width direction (X direction) are also closed, so the bag body 2 as a whole is a bottomed cylindrical shape. Near the opening 6 of the bag body 2, there is an open end 61 on the side of the one end 21 in the width direction of the bag body 2, and an open end 62 on the side of the other end 22.

[0033] Then, the connector 300 and a portion of the electric wire 301 are housed inside the bag body 2. In this state, the open end 61 on the one end 21 side is folded inward toward the other end 22, on the inside of the surface sheet 3 and the back sheet 4. Similarly, the open end 62 on the other end 22 side is also folded inward toward the one end 21, on the inside of the surface sheet 3 and the back sheet 4.

[0034] The open end 61 on one end 21 and the open end 62 on the other end 22 are joined to each other by a joint 10. Furthermore, the inner surfaces of the surface sheet 3 and the back sheet 4 facing the joint between the open end 61 on one end 21 and the open end 62 on the other end 22 are also joined by the joint 10. In other words, the open end 61 on one end 21 and the open end 62 on the other end 22, as well as the surface sheet 3 and the back sheet 4, are joined by a single joint 10. In Figure 2A, the joint 10 is provided between multiple electric wires 301.

[0035] The method of joining the open ends 61, 62 and the surface sheet 3 and back sheet 4 is not particularly limited and can be done by heat welding or adhesive. However, as will be described later, when manufacturing the dust cover 1A for the connector, it is preferable to first join the open ends 61, 62 and then join the surface sheet 3 and back sheet 4. For this reason, it is preferable to use an adhesive for joining these parts.

[0036] In the connector dust cover 1A, a closed space is formed by the surface sheet 3, the back sheet 4, and the joint 10. Furthermore, the connector 300 and a portion of the electric wire 301 are housed inside this closed space. Therefore, since the connector 300 is protected from dust by the connector dust cover 1A, it is possible to suppress the accumulation of dust and other debris inside the connector 300. In addition, with the connector 300 housed inside the connector dust cover 1A, the width W1 of the opening 6 located around the electric wire 301 is smaller than the width W2 of the connector 300. Furthermore, the opening ends 61, 62 and the joint 10 that connects the surface sheet 3 and the back sheet 4 are provided between multiple electric wires 301. Therefore, when transporting a wire harness equipped with a connector 300 covered by the connector dust cover 1A, it is possible to suppress the connector dust cover 1A from falling off the connector 300.

[0037] To remove the connector dust cover 1A, for example, an operator can grasp the vicinity of the bottom 5 of the connector dust cover 1A and pull it up, causing the connector 300 and the joint 10 to come into contact. Furthermore, by pulling up the connector dust cover 1A, the joint 10 breaks, the open end 61 on one end 21 and the open end 62 on the other end 22 separate, and the surface sheet 3 and the back sheet 4 also separate, widening the opening 6. After that, by pulling up the connector dust cover 1A further, the connector dust cover 1A can be removed from the connector 300.

[0038] Next, the manufacturing method of the dust cover 1A for connectors of this embodiment will be described. First, as shown in Figure 2B, a bottomed cylindrical bag body 2 is prepared in which the entire bottom 5 of the surface sheet 3 and the back sheet 4, the entire one end 21, and the entire other end 22 are closed. At this time, an opening 6 is provided at the entire lower end of the bag body 2.

[0039] Next, as shown in Figure 2C, the connector 300 and a portion of the electric wire 301 are housed inside the bag 2. In this state, the open end 61 on one end 21 is folded inward toward the other end 22, towards the inside of the surface sheet 3 and the back sheet 4. Furthermore, the open end 62 on the other end 22 is also folded inward toward the one end 21, towards the inside of the surface sheet 3 and the back sheet 4. Then, the open end 61 on one end 21 and the open end 62 on the other end 22 are joined together.

[0040] Subsequently, as shown in Figure 2A, the joint portion 10 can be formed by joining the joint portion between the open end 61 on one end 21 and the open end 62 on the other end 22 with the inner surface of the surface sheet 3 and the inner surface of the back sheet 4 facing the joint portion. Through this simple process, the dust cover 1A for the connector can be manufactured.

[0041] As described above, the dust cover 1A for the connector in this embodiment has a front sheet 3 and a back sheet 4 joined at a joint 10, and the joint 10 is formed using only one method. Therefore, dust protection for the connector 300 can be implemented with a simple structure while suppressing the generation of waste from the dust cover 1A for the connector.

[0042] [Third Embodiment] Next, the dust cover 1B for the connector according to the third embodiment will be described in detail with reference to the drawings.

[0043] As shown in Figure 3, the dust cover 1B for the connector in this embodiment includes a bag-like body 2 that is substantially rectangular when viewed from above. The bag-like body 2 is substantially rectangular and includes a front sheet 3 and a back sheet 4 that are substantially the same size.

[0044] The upper end of the bag body 2 in the longitudinal direction (Y direction) is provided with a closed bottom 5, and the lower end is provided with an opening 6. The entire left end 21 and the entire right end 22 of the bag body 2 in the width direction (X direction) are also closed, so the bag body 2 as a whole is a bottomed cylindrical shape.

[0045] The connector 300 and a portion of the electric wire 301 are housed inside the bag body 2, and the connector 300 is positioned towards one end 21 in the width direction of the bag body 2. In this state, a third joint portion 13 is provided on the other end 22 in the width direction of the bag body 2 of the connector 300. The third joint portion 13 is a portion formed by joining the surface sheet 3 and the back sheet 4. The method of joining the surface sheet 3 and the back sheet 4 is not particularly limited and can be done by heat welding or adhesive.

[0046] The third joint 13 may be provided along the entire other end 22 side of the connector 300, or, as shown in Figure 3, it may be provided only near the center in the longitudinal direction (Y direction) of the other end 22 side of the connector 300. The distance between one end 21 of the bag body 2 and the third joint 13 is greater than the width W2 of the connector 300.

[0047] The bag body 2 has a connector 300 positioned towards one end 21 in the width direction of the bag body 2, and a fourth joint 14 is provided on the other end 22 in the width direction of the electric wire 301. The fourth joint 14 is also a part formed by joining the surface sheet 3 and the back sheet 4. The method of joining the surface sheet 3 and the back sheet 4 is not particularly limited and can be done by heat welding or adhesive. However, the joining method for the third joint 13 and the fourth joint 14 is the same.

[0048] An opening 6 is formed between one end 21 of the bag body 2 in the width direction and the fourth joint 14. In the width direction of the bag body 2, the distance between one end 21 of the bag body 2 and the fourth joint 14 is smaller than the width W2 of the connector 300. Note that one end 21 of the bag body 2 and the fourth joint 14 are located in the vicinity of the electric wire 301 connected to the connector 300. Therefore, the opening 6 of the bag body 2 is provided around the electric wire 301.

[0049] In the connector dust cover 1B, a closed space is formed by the surface sheet 3, the back sheet 4, and the fourth joint 14. Furthermore, the connector 300 and a portion of the electric wire 301 are housed inside this closed space. As a result, the connector 300 is protected from dust by the connector dust cover 1B, preventing dust and other debris from adhering to the inside of the connector 300. Also, with the connector 300 housed inside the connector dust cover 1B, the width W1 of the opening 6 of the bag body 2 is smaller than the width W2 of the connector 300. Therefore, when transporting a wire harness equipped with the connector 300 covered by the connector dust cover 1B, it is possible to prevent the connector dust cover 1B from falling off the connector 300. In addition, by providing the third joint 13, the connector 300 is held between one end 21 of the bag body 2 and the third joint 13, making it difficult for the connector 300 to move inside the bag body 2, and allowing the connector 300 to be held in a stable state.

[0050] To remove the connector dust cover 1B, for example, an operator can grasp the vicinity of the bottom 5 of the connector dust cover 1B and pull it up, causing the connector 300 to come into contact with the fourth joint 14. Further pulling up the connector dust cover 1B causes the fourth joint 14 to break, separating the surface sheet 3 and the back sheet 4, and widening the opening 6. Subsequently, by pulling up the connector dust cover 1B further, the connector dust cover 1B can be removed from the connector 300.

[0051] Next, the manufacturing method of the dust cover 1B for connectors of this embodiment will be described. First, as shown in Figure 2B, a bottomed cylindrical bag body 2 is prepared in which the entire bottom 5 of the surface sheet 3 and the back sheet 4, the entire one end 21, and the entire other end 22 are closed. At this time, an opening 6 is provided at the entire lower end of the bag body 2.

[0052] Next, as shown in Figure 2C, the connector 300 and a portion of the electric wire 301 are housed inside the bag 2. Then, as shown in Figure 3, the connector 300 is moved towards one end 21 in the width direction of the bag 2, and a third joint portion 13 is formed on the other end 22 in the width direction of the bag 2 of the connector 300. The method of joining the surface sheet 3 and the back sheet 4 is not particularly limited and can be done by heat welding or adhesive.

[0053] Then, a fourth joint portion 14 is formed on the other end 22 side in the width direction of the bag body 2 of the electric wire 301. Through this simple process, the dust cover 1B for the connector can be manufactured.

[0054] As described above, the dust cover 1B for the connector in this embodiment has a surface sheet 3 and a back sheet 4 joined at a third joint 13 and a fourth joint 14, and furthermore, the third joint 13 and the fourth joint 14 are formed using only one method. Therefore, dust protection measures for the connector 300 can be implemented with a simple structure while suppressing the generation of waste from the dust cover 1B for the connector.

[0055] In Figure 3, the dust cover 1B for the connector has the connector 300 positioned towards one end 21 in the width direction of the bag body 2. However, the embodiment is not limited to this one. Alternatively, the connector 300 may be positioned towards the other end 22 in the width direction of the bag body 2, and then a third joint portion 13 may be provided on the end 21 in the width direction of the bag body 2 of the connector 300, and a fourth joint portion 14 may be provided on the end 21 in the width direction of the bag body 2 of the electric wire 301.

[0056] [Fourth Embodiment] Next, the dust cover 1C for the connector according to the fourth embodiment will be described in detail with reference to the drawings.

[0057] As shown in Figure 4, the connector dust cover 1C of this embodiment is an embodiment in which the third joint portion 13 is not provided in the connector dust cover 1B of the third embodiment, and only the fourth joint portion 14 is provided as the joint portion 10. In other words, in the connector dust cover 1C, with the connector 300 positioned at one end 21 in the width direction (X direction) of the bag body 2, the joint portion 10 is formed on the other end 22 side of the width direction of the bag body 2 on the electric wire 301.

[0058] As with the dust cover 1B for connectors described above, by providing a third joint 13, the connector 300 is held between one end 21 of the bag body 2 and the third joint 13, making it difficult for the connector 300 to move inside the bag body 2 and allowing the connector 300 to be held stably. However, even with the dust cover 1C for connectors, a closed space is formed by the surface sheet 3, the back sheet 4 and the joint 10, and the connector 300 and a part of the electric wire 301 are housed inside this closed space, with an opening 6 formed between one end 21 of the bag body 2 and the joint 10. Furthermore, in the width direction of the bag body 2, the distance between one end 21 of the bag body 2 and the joint 10 is smaller than the width W2 of the connector 300.

[0059] Therefore, since the connector 300 is protected from dust by the connector dust cover 1C, it is possible to suppress the accumulation of dust and other debris inside the connector 300. Furthermore, since the connector dust cover 1C forms only one joint 10, dust protection for the connector 300 can be implemented with a simpler structure compared to the connector dust cover 1B.

[0060] [Fifth Embodiment] Next, the dust cover 1D for the connector according to the fifth embodiment will be described in detail with reference to the drawings.

[0061] As shown in Figure 5, the dust cover 1D for the connector in this embodiment includes a bag-like body 2 that is substantially rectangular when viewed from above. The bag-like body 2 is substantially rectangular and includes a front sheet 3 and a back sheet 4 that are substantially the same size.

[0062] The upper end of the bag body 2 in the longitudinal direction (Y direction) is provided with a closed bottom 5, and the lower end is provided with an opening 6. The entire left end 21 and the entire right end 22 of the bag body 2 in the width direction (X direction) are also closed, so the bag body 2 as a whole is a bottomed cylindrical shape.

[0063] The connector 300 and a portion of the electric wire 301 are then housed inside the bag 2. In this state, two joints 10 are provided on both the one end 21 and the other end 22 of the bag 2 in the width direction of the electric wire 301. The joints 10 are formed by joining the surface sheet 3 and the back sheet 4. The method of joining the surface sheet 3 and the back sheet 4 is not particularly limited and can be done by heat welding or adhesive. The joining method is the same for both the joints 10 on the one end 21 and the other end 22.

[0064] An opening 6 is formed between the joint 10 on one end 21 and the joint 10 on the other end 22 in the width direction of the bag body 2. The distance between the joint 10 on one end 21 and the joint 10 on the other end 22 in the width direction of the bag body 2 is smaller than the width W2 of the connector 300. The joint 10 on one end 21 and the joint 10 on the other end 22 are located near the electric wire 301 connected to the connector 300. Therefore, the opening 6 of the bag body 2 is provided around the electric wire 301.

[0065] In the connector dust cover 1D, a closed space is formed by the surface sheet 3, the back sheet 4, and the two joints 10. Furthermore, the connector 300 and a portion of the electric wire 301 are housed inside this closed space. As a result, the connector 300 is protected from dust by the connector dust cover 1D, which prevents dust and other debris from adhering to the inside of the connector 300. In addition, with the connector 300 housed inside the connector dust cover 1D, the width W1 of the opening 6 located around the electric wire 301 is smaller than the width W2 of the connector 300. Therefore, when transporting a wire harness equipped with the connector 300 covered by the connector dust cover 1D, it is possible to prevent the connector dust cover 1D from falling off the connector 300.

[0066] To remove the connector dust cover 1D, for example, an operator can grasp the vicinity of the bottom 5 of the connector dust cover 1D and pull it up, causing the connector 300 and the joint 10 to come into contact. Further pulling up the connector dust cover 1D causes the joint 10 to break, separating the surface sheet 3 and the back sheet 4, and widening the opening 6. Subsequently, by pulling up the connector dust cover 1D further, the connector dust cover 1D can be removed from the connector 300.

[0067] Next, the manufacturing method of the dust cover 1D for the connector of this embodiment will be described. First, as shown in Figure 2B, a bottomed cylindrical bag body 2 is prepared in which the entire bottom 5 of the surface sheet 3 and the back sheet 4, the entire one end 21, and the entire other end 22 are closed. At this time, an opening 6 is provided at the entire lower end of the bag body 2.

[0068] Next, as shown in Figure 2C, the connector 300 and a portion of the electric wire 301 are housed inside the bag 2. Then, as shown in Figure 5, two joints 10 are formed on one end 21 and the other end 22 of the electric wire 301 in the width direction of the bag 2. The method of joining the surface sheet 3 and the back sheet 4 is not particularly limited and can be done by heat welding or adhesive. Through such a simple process, the dust cover 1D for the connector can be manufactured.

[0069] As described above, the dust cover 1D for the connector in this embodiment has a front sheet 3 and a back sheet 4 joined at a joint 10, and the joint 10 is formed using only one method. Therefore, dust protection for the connector 300 can be implemented with a simple structure while suppressing the generation of waste from the dust cover 1D for the connector.

[0070] [Sixth Embodiment] Next, the dust cover 1E for the connector according to the sixth embodiment will be described in detail with reference to the drawings.

[0071] As shown in Figure 6, the dust cover 1E for the connector in this embodiment includes a bag-like body 2 that is roughly rectangular when viewed from above. The bag-like body 2 is roughly rectangular and includes a front sheet 3 and a back sheet 4 that are roughly the same size.

[0072] The upper end of the bag body 2 in the longitudinal direction (Y direction) is provided with a closed bottom 5, and the lower end is provided with an opening 6. The entire left end 21 and the entire right end 22 of the bag body 2 in the width direction (X direction) are also closed, so the bag body 2 as a whole is a bottomed cylindrical shape. As shown in Figure 2C, near the opening 6 of the bag body 2, there is an open end 61 on the side of the end 21 in the width direction of the bag body 2, and an open end 62 on the side of the other end 22. Also, near the bottom 5 of the bag body 2, there is a bottom end 51 on the side of the end 21 in the width direction of the bag body 2, and a bottom end 52 on the side of the other end 22.

[0073] The connector 300 and a portion of the electric wire 301 are housed inside the bag body 2. In this state, the open end 62 on the other end 22 side of the surface sheet 3 of the bag body 2 is bent toward the center of the surface sheet 3. Furthermore, the bottom end 51 on the one end 21 side of the surface sheet 3 of the bag body 2 is bent toward the center of the surface sheet 3. At least a portion of the open end 62 and the bottom end 51 are laminated. The laminated portion of the open end 62 and the bottom end 51 and the surface sheet 3 opposite the laminated portion are joined by a single joint 10. The position of the joint 10 is not particularly limited, but for example, it can be on the diagonal between the open end 62 and the bottom end 51 of the surface sheet 3.

[0074] The method of joining the open end 62, the bottom end 51, and the surface sheet 3 is not particularly limited and can be done by heat welding or adhesive.

[0075] In the connector dust cover 1E, a closed space is formed by the surface sheet 3, the back sheet 4, and the joint 10. Furthermore, the connector 300 and a portion of the electric wire 301 are housed inside this closed space. As a result, the connector 300 is protected from dust by the connector dust cover 1E, which prevents dust and other debris from adhering to the inside of the connector 300. In addition, with the connector 300 housed inside the connector dust cover 1E, the width W1 of the opening 6 located around the electric wire 301 is smaller than the width W2 of the connector 300. Therefore, when transporting a wire harness equipped with the connector 300 covered by the connector dust cover 1E, it is possible to prevent the connector dust cover 1E from falling off the connector 300.

[0076] To remove the connector dust cover 1E, the worker grasps the joint 10 and pulls it up, causing the joint 10 to break and separating the open end 62 and the bottom end 51. This causes the folded surface sheet 3 and back sheet 4 to return to a roughly rectangular shape, widening the opening 6. After that, the worker grasps the vicinity of the bottom 5 of the connector dust cover 1E and pulls it up, allowing the connector dust cover 1E to be removed from the connector 300.

[0077] Next, the manufacturing method of the dust cover 1E for connectors of this embodiment will be described. First, as shown in Figure 2B, a bottomed cylindrical bag body 2 is prepared in which the entire bottom 5 of the surface sheet 3 and the back sheet 4, the entire one end 21, and the entire other end 22 are closed. At this time, an opening 6 is provided at the entire lower end of the bag body 2.

[0078] Next, as shown in Figure 2C, the connector 300 and a portion of the electric wire 301 are housed inside the bag 2. Then, the open end 62 on the other end 22 of the bag 2 is folded toward the center of the surface sheet 3. Furthermore, the bottom end 51 on one end 21 of the bag 2 is folded toward the center of the surface sheet 3. At this time, the open end 62 and the bottom end 51 are at least partially overlapped.

[0079] Then, the laminated portions of the open end 62 and the bottom end 51 are joined to the surface sheet 3 facing the laminated portion to form a joint 10. The method of joining the open end 62, the bottom end 51 and the surface sheet 3 is not particularly limited and can be done by heat welding or adhesive. Through such a simple process, a dust cover 1E for connectors can be manufactured.

[0080] As described above, the dust cover 1E for the connector in this embodiment has the opening end 62, the bottom end 51, and the surface sheet 3 joined at the joint 10, and furthermore, the joint 10 is formed by only one method. Therefore, dust protection measures for the connector 300 can be implemented with a simple structure while suppressing the generation of waste from the dust cover 1E for the connector.

[0081] In the dust cover 1E for the connector shown in Figure 6, the open end 62 on the other end 22 side and the bottom end 51 on the one end 21 side are joined together. However, the embodiment is not limited to this one, and the open end 61 on the one end 21 side and the bottom end 52 on the other end 22 side may be joined together instead.

[0082] As described in the first to sixth embodiments above, the connector dust covers 1, 1A, 1B, 1C, 1D, and 1E are covers that are fitted to cover the connector 300 and protect it from dust. The connector dust cover comprises a bag body 2 having an opening 6. The connector dust cover also houses the connector 300 inside the bag body 2, covering the entire connector, and the opening 6 of the bag body 2 is provided around the electric wire 301 connected to the connector 300. By joining a part of the bag body 2 with only one type of joint 10, the width W1 of the opening 6 located around the electric wire 301 is smaller than the width W2 of the connector 300 when the connector 300 is housed inside the bag body 2.

[0083] The dustproof covers for connectors 1, 1A, 1B, 1C, 1D, and 1E protect the connector 300 from dust by joining a portion of the bag body 2 with only one type of joint 10. Therefore, dustproof measures for the connector 300 can be implemented with a simple structure using the dustproof covers for connectors 1, 1A, 1B, 1C, 1D, and 1E. In other words, the protective cover in Patent Document 1 has multiple joining means because both sides of the resin sheet are heat-sealed to form a closed section, and the opening is further closed with adhesive tape. However, in the dustproof cover for connectors of this embodiment, a portion of the bag body 2 is joined with only one type of joint 10, resulting in a simple structure. Therefore, the manufacturing time of the dustproof cover for connectors can be shortened, and the time required to remove the dustproof cover for connectors can also be shortened. Furthermore, because only one type of joint 10 is formed on the bag body 2, the equipment for forming the joint 10 can be simplified, and the control of the equipment can be made easier. In addition, because the equipment can be simplified, it becomes easier to maintain consistent quality for the dustproof cover for connectors. As a result, the cost of dustproofing connector 300 can be reduced.

[0084] In the dustproof covers for connectors 1, 1A, 1B, 1C, 1D, and 1E, the joint portion 10 may be made of a heat-sealed portion formed by heat-welding a part of the bag body 2, or of an adhesive.

[0085] In the protective cover described in Patent Document 1, after covering the attached member with a bag, the release paper is peeled off and the opening is sealed with adhesive, resulting in the release paper becoming waste. Furthermore, conventional dust covers used slit tape, which generated waste of tape and the core material around which the tape was wound. However, in the dust cover for connectors of this embodiment, the joint 10 can be constructed with a heat-welded joint or adhesive, thus reducing waste. Moreover, by constructing the joint 10 with a heat-welded joint or adhesive, concerns such as tape peeling off during transport are eliminated, and the dust cover can be easily removed from the connector. In addition, slit tape may become excessively softened in high-temperature environments and adhere to workers, but this can be suppressed by constructing the joint 10 with a heat-welded joint.

[0086] In the dustproof covers for connectors 1, 1A, 1B, 1C, and 1D, the width W1 of the opening 6 located around the electric wire 301 may be smaller than the width W2 of the connector 300 by joining the front sheet 3 and back sheet 4 of the bag body 2 at the joint 10. With this configuration, dustproofing measures for the connector 300 can be implemented with a simple structure.

[0087] In the dust cover 1 for the connector, the joint portion 10 may include a first joint portion 11 provided at both ends in the width direction of the bag body 2, extending from the bottom 5 toward the opening, and a second joint portion 12 provided so as to continuously decrease in diameter from the opening-side ends 113, 114 of the first joint portion 11 toward the opening 6. With such a configuration, dust protection measures for the connector 300 can be implemented with a simple structure.

[0088] In the dust cover 1A for the connector, both opening ends 61 and 62 in the width direction of the bag body 2 may be folded inward towards the inside of the surface sheet 3 and the back sheet 4, and both opening ends 61 and 62 may be joined to the surface sheet 3 and the back sheet 4 at the joint 10. With this configuration, dust protection for the connector 300 can be provided with a simple structure.

[0089] In the dust cover 1B for the connector, the joint portion 10 may include a third joint portion 13 provided on the other end 22 of the bag body 2 in the width direction of the connector 300, and a fourth joint portion 14 provided on the other end 22 of the bag body 2 in the width direction of the electric wire 301, with the connector 300 positioned against one end 21 of the bag body 2 in the width direction. With this configuration, dust protection for the connector 300 can be provided with a simple structure.

[0090] In the dust cover 1C for the connector, the connector 300 may be positioned close to one end 21 in the width direction of the bag body 2, and a joint portion 10 may be formed on the other end 22 in the width direction of the electric wire 301. With this configuration, dust protection for the connector 300 can be provided with a simple structure.

[0091] In the dust cover 1D for the connector, joint portions 10 may be formed on both the one end 21 and the other end 22 in the width direction of the bag body 2 on the electric wire 301. With such a configuration, dust protection measures for the connector 300 can be implemented with a simple structure.

[0092] In the dust cover 1E for the connector, by joining one of the opening ends 61, 62 of the surface sheet 3 of the bag body 2 to the surface sheet 3 with a joint 10, the width W1 of the opening 6 located around the electric wire 301 may be smaller than the width W2 of the connector 300. With this configuration, dust protection for the connector 300 can be provided with a simple structure.

[0093] The dustproof structure of the connector 300 according to this embodiment includes a connector 300 to which an electric wire 301 is connected, and dustproof connector covers 1, 1A, 1B, 1C, 1D, 1E that are fitted to cover the connector 300 and protect it from dust. By using the dustproof connector covers of this embodiment, dustproof measures for the connector 300 can be implemented with a simple structure.

[0094] Furthermore, the dust cover for the connector in this embodiment may be any combination of the configurations from the first to sixth embodiments. Also, a bag with a gusset may be used as the bag body 2.

[0095] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment. [Explanation of Symbols]
