Description

[Technical Field]

[0001] The present invention relates to a connector cover that is attached to a connector that connects harnesses (electric wires) together. [Background technology]

[0002] In equipment where water-carrying pipes and harnesses are installed close to each other, such as water treatment equipment and dialysis equipment, the connectors connecting the harnesses must be covered to prevent them from getting wet. Conventional methods for preventing the connectors from getting wet include covering them with a plastic bag and sealing the opening with a vinyl tie, or covering the male and female connectors with vinyl chloride or other materials shaped to resemble the connectors.

[0003] However, during maintenance and inspection, the process of removing the plastic bag from the connector, then replacing it and sealing it with a vinyl tie is cumbersome and time-consuming. While various connector covers that can be attached and detached during maintenance and inspection are known, the method of covering each male and female connector with a vinyl chloride connector cover shaped like the connector requires wiring before assembling the connector, which is time-consuming.

[0004] For example, Patent Document 1 discloses a drip-proof cover that is attached to a power distributor of an internal combustion engine such as an automobile engine to protect cable connection terminals from water intrusion, salt damage, and the like.

[0005] Patent Document 2 discloses a connector cover that includes a cover body, a cover lid, and a hinge or the like that connects them. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 2-89774 [Patent Document 2] Japanese Patent Publication No. 2022-127242 Summary of the Invention [Problem to be solved by the invention]

[0007] Generally, when assembling a water treatment device or dialysis device, if a cover is to be attached to a connector, the attachment work is often performed after the male / female connection work of the harness connector is completed. Therefore, a cover that can be attached over the harness and connector is easy to work with. Furthermore, it is even better if the cover is designed to be easily attached and removed during regular or irregular maintenance inspections after the device has started operating.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a connector cover that can be easily attached to and detached from a connector that connects harnesses together. [Means for solving the problem]

[0009] In order to solve the above problems, the connector cover according to the present invention comprises: A connector cover to be attached to a connector that connects harnesses together, a first cover member having a recess at an opening end for bundling the plurality of harnesses and guiding them from the inside of the cover to the outside of the cover; and a second cover member fitted to the first cover member, The second cover member is characterized by having a holding mechanism for holding the harness along the outer surface of the cover.

[0010] The connector cover of the present invention can easily protect the connector of a device with a harness already connected to it. In particular, the connector cover has a structure in which the first cover member and the second cover member are fitted together to hold the harness along the outer surface of the cover, allowing for a neat and tidy harness layout. Furthermore, by passing the control harness through the harness retaining tube of the second cover, the second cover always faces upward relative to the first cover, providing better protection against liquids from above.

[0011] In the connector cover of the present invention, it is preferable that the outer cover surface of the opening end of the first cover member is fitted with the inner cover surface of the opening end of the second cover member. By configuring the connector to be covered by fitting the two cover members together, the processing of the cover members can be simplified, and manufacturing can be performed using a method such as dip molding, which requires inexpensive molds, thereby enabling low-cost manufacturing. Furthermore, by storing the first cover member in the second cover member, paired storage can be achieved and the storage volume can be reduced.

[0012] In the connector cover of the present invention, it is preferable that a recess provided on the surface of one of the first and second cover members is fitted with a protrusion provided on the surface of the other cover member, thereby restricting the mating length and installation orientation. By restricting the mating length by fitting the recess and protrusion, it is possible to prevent the mating state from becoming too deep or too shallow. Furthermore, by providing the recess and protrusion on the first cover and the second cover in one location, the installation orientation can be restricted.

[0013] In the connector cover of the present invention, it is preferable that a through hole be provided in the outer surface of the first cover member, and a raised portion be formed around the through hole that is raised from the outer surface. The provision of the through hole prevents moisture from accumulating inside the cover, and the provision of the raised portion improves the ease of attaching and detaching the cover, for example by allowing the cover member to be pinched with fingers when attaching or detaching the cover attached to the connector.

[0014] In the connector cover of the present invention, it is preferable that at least a portion of the first cover member and the second cover member be transparent or translucent. By using transparent or translucent cover members, not only can the state of the connector be easily visually confirmed from the outside when the cover is attached, but also, in cases where connectors are color-coded by type to prevent operational errors, connector types can be easily identified by their appearance, for example, by numbering, even when the cover is attached.

[0015] In the connector cover of the present invention, the first and second cover members are preferably made of polyvinyl chloride. By forming the cover members from polyvinyl chloride, the insulation and transparency of the cover can be ensured. Furthermore, by using polyvinyl chloride, the cover can be flexibly deformed when attached and detached, improving workability during maintenance. [Effects of the Invention]

[0016] According to the connector cover of the present invention, it is possible to provide a cover that can be easily attached to and detached from a connector at low manufacturing costs. [Brief explanation of the drawings]

[0017] [Figure 1] 1 is a perspective view of a connector cover according to an embodiment of the present invention. [Figure 2] 2A and 2B are perspective views showing the connector cover of FIG. 1 before and after it is attached to the connector, in which (A) shows the state before attachment and (B) shows the state after attachment. [Figure 3] 10A and 10B are front and rear perspective views of a connector cover according to another embodiment of the present invention being attached to a connector, where FIG. 10A shows the state before attachment and FIG. DETAILED DESCRIPTION OF THE INVENTION

[0018] A preferred embodiment of the present invention will be described below with reference to the drawings. The dashed lines and two-dot chain lines in the drawings indicate the internal structure of the cover, which can be seen from the outside of the cover if the cover member is made of a transparent or translucent material.

[0019] FIG. 1 is a perspective view of a connector cover 1 according to one embodiment of the present invention. In the first cover member 1a, a recess 3 is formed at the opening end 2a for bundling harnesses and guiding them from the inside to the outside of the cover, a rounded protrusion 4 like a sphere is formed on the outer surface, and a raised portion 5 is formed on the bottom surface opposite the opening end 2a, with a through-hole 6 in the raised portion 5. When attaching or detaching the connector cover 1, pinching the raised portion 5 with the fingers makes it easy to remove the first cover member 1a. Furthermore, moisture is discharged to the outside of the cover through the through-hole 6, preventing moisture from building up inside the cover.

[0020] The second cover member 1b has a harness holding tube 7 for holding the harness along the outer surface of the cover, and a recess 8 formed on its inner surface into which the protrusion 4 can be fitted. By pushing the first cover member 1a all the way into the second cover member 1b along the same direction as the position of the protrusion 4 of the first cover member 1a and the recess 8 of the second cover member 1b, the first cover member 1a and the second cover member 1b can be paired and stored, and the storage volume can be reduced at the same time.

[0021] 2A and 2B are perspective views of the first cover member 1a and the second cover member 1b, with (A) showing the state before the cover is attached to the connector 9 and (B) showing the state after the cover is attached. In FIG. 2A, the control panel side harness 10a is inserted into the harness holding tube 7 and extends upward, and the device side harness 10 passes through the connector 9 and is guided by the recess 3 from inside the cover to outside the cover, extending downward. When the open end 2b of the second cover member 1b is fitted onto the outer surface of the open end 2a of the first cover member 1a so as to cover the connector 9 that connects multiple harnesses 10 together and is then slid, the protrusion 4 is fitted into the recess as shown in FIG. 2B, and the fitting length of the first cover member 1a and the second cover member 1b is restricted.

[0022] In addition, in Figure 2(A), there is one protrusion 4 on the second cover member 1b and one recess 8 on the first cover member 1a so that the harness retaining tube 7 on the second cover member 1b and the recess 3 on the first cover member 1a match, thereby regulating the installation orientation of the first cover member 1a and the second cover member 1b.

[0023] 2(B), the connector cover 1 attached to the connector 9 is positioned so that the second cover member 1b is always on the upper side and the first cover member 1a is on the lower side along the control panel side harness 10a that extends vertically so as to pass through the harness holding tube 7 and the recess 3, so that the wiring state after the cover is attached looks neat and tidy. In addition, the control panel side harness 10a is guided by the harness holding tube 7 and the recess 3 and is shaped to rise toward the inside of the cover, so that even if rainwater or the like adhering to the control panel side harness 10a trickles down to the vicinity of the connector cover 1, it is possible to prevent water from entering the inside of the cover.

[0024] When the cover member is made of a relatively hard resin material, the recess 3 needs to be processed to have a concave shape. However, when the cover member is made of a soft material such as polyvinyl chloride resin, the recess 3 can be formed by taking advantage of the fact that when the connector cover 1 is attached to the connector 9 and harness 10, the cover member that abuts against the harness 10 becomes partially concave.

[0025] A slit or gap extending in the longitudinal direction is provided on the circumferential surface of the harness holding tube 7, allowing the control panel side harness 10a, which has already been wired, to be passed through the tube. If the harness holding tube 7 is made of a soft material such as polyvinyl chloride resin, a slit can be provided instead of a gap, and the gap can be closed after the control panel side harness 10a has been passed through the tube.

[0026] 3A and 3B are perspective views of a connector cover 11 according to another embodiment of the present invention, in which (A) shows the state before the cover is attached to the connector 19 and (B) shows the state after the cover is attached. Compared to FIG. 2, the number of harnesses included in the bundle of harnesses 10 is greater, and therefore the size of the connector 19 that connects more harnesses together is also larger.

[0027] The harness holding tube 17 and the recess 13 are provided at the corners of the second cover member 11b, and the space at the corners can be used to compactly accommodate a large number of harnesses. [Industrial Applicability]

[0028] The connector cover of the present invention can be widely used to prevent liquid from spilling on devices in which water-flowing pipes and electrical wiring are installed in close proximity, as it can easily cover the connectors from above even when the male and female connectors of the harness are connected.
